CIERRE DE ENVASE CONTAINER CLOSURE
DESCRIPCIÓNDESCRIPTION
Campo de la invenciónField of the Invention
La invención se refiere a un cierre de envase, donde el envase dispone de un orificio de salida, que comunica el interior del envase con el exterior, y donde el cierre es del tipo que es apto para ser montado en el orificio de salida y hacer un cierre estanco con el orificio de salida. El cierre comprende una primera parte hinchable y una segunda parte apta para fijarse en el orificio de salida.The invention relates to a container closure, where the container has an outlet opening, which communicates the inside of the package with the outside, and where the closure is of the type that is suitable for being mounted in the exit hole and making a tight seal with the outlet hole. The closure comprises a first inflatable part and a second part suitable for fixing in the outlet opening.
Estado de la técnicaState of the art
Es habitual el uso de envases, en multitud de ocasiones, para contener cualquier tipo de productos. Los envases son, por tanto, aptos para ser llenados o vaciados de algún producto, por lo que presentan siempre un orificio de salida, de dimensiones adecuadas al producto a contener. Frecuentemente es conveniente poder cerrar el orificio de salida de estos envases, para lo cual se cuenta con un cierre o tapón. Son conocidos los tapones de envases, que sirven para cerrar un envase de una manera estanca, de tal manera que se impide el paso del aire o de cualquier otro gas desde el interior del envase al exteπor, en el caso de hallarse el interior a una presión superior a la existente en el exterior, y viceversa, en el caso de hallarse el interior a una presión inferior a la existente en el exterior. Toda clase de bebidas, con o sin gas, productos de higiene personal (champús, jabones líquidos, colonias, cremas para el cuidado de la piel, etc.), productos de limpieza del hogar (detergentes líquidos, suavizantes de ropa, etc.), incluso algunos envases de pelotas de tenis, son ejemplos de los envases citados anteriormente.It is common to use containers, in many occasions, to contain any type of products. The containers are, therefore, suitable to be filled or emptied of some product, so they always have an exit hole, of adequate dimensions to the product to be contained. Frequently it is convenient to be able to close the outlet opening of these containers, for which there is a closure or cap. Container caps are known, which serve to close a container in a sealed manner, in such a way that the passage of air or any other gas from the interior of the container to the extensor is prevented, if the interior is located at a pressure higher than that existing outside, and vice versa, if the interior is at a pressure lower than that existing outside. All kinds of drinks, with or without gas, personal hygiene products (shampoos, liquid soaps, colognes, skin care creams, etc.), household cleaning products (liquid detergents, fabric softeners, etc.) , even some containers of tennis balls, are examples of the aforementioned containers.
Son conocidos los cierres o tapones de envase que incluyen un elemento adicional que signifique un atractivo adicional para la compra del producto, concretamente que comprenden una primera parte hinchable y una segunda parte apta para fijarse en el orificio de salida del envase, y que, cuando el cierre o tapón está montado en el orificio de salida, el interior de dicha primera parte hinchable está en comunicación con el interior del envase. Estos tapones han sido descritos en el documento ES U9900951 , publicado el 16.9.99, y que se incorpora en la presente por referencia.Container closures or caps are known which include an additional element that means an additional attraction for the purchase of the product, specifically comprising a first inflatable part and a suitable second part. to be fixed in the exit hole of the container, and that, when the closure or cap is mounted in the exit hole, the interior of said first inflatable part is in communication with the interior of the container. These plugs have been described in document ES U9900951, published on 16.9.99, and which is incorporated herein by reference.
-En estos tapones, en el caso de un envase que contenga un líquido gasificado, usualmente una bebida refrescante, la primera parte hinchable se hinchará gracias a la sobrepresión generada por el gas que se desprende del líquido al ser agitado el envase, lo que constituye un claro efecto de reclamo y un atractivo adi- cional para la venta del producto. Posteriormente se puede deshinchar la primera parte hinchable, bien dejando transcurrir un tiempo para que el gas se reabsorba y/o se escape hacia el exterior, en el caso de no ser el cierre absolutamente estanco, o bien simplemente separando el tapón del recipiente y permitiendo una salida más rápida del gas acumulado en el interior de la primera parte hinchable. En el caso de que el envase sea elástico se puede producir otro efecto, consistente en que al apretar el envase, por ejemplo con la mano, éste cede a la presión exterior, deformándose, y se produce una sobrepresión interior que hará hincharse la primera parte hinchable del tapón. Asimismo ocurrirá el efecto contrario: si una vez hinchada la primera parte hinchable del tapón, se mantiene la deformación y se deja transcurrir un tiempo para que la sobrepresión existente en el interior del envase se reduzca, debido a una salida del gas contenido en el interior del envase hacia el exterior, y posteriormente se libera rápidamente la presión exterior, por ejemplo abriendo la mano, permitiendo que el envase adquiera su forma original, se crea una depresión en el interior del envase que tiende a succionar la primera parte hinchable del tapón hacia el interior del envase.-In these caps, in the case of a container containing a gasified liquid, usually a refreshing drink, the first inflatable part will swell thanks to the overpressure generated by the gas that is released from the liquid when the container is agitated, which constitutes a clear claim effect and an additional appeal for the sale of the product. Subsequently, the first inflatable part can be deflated, either allowing time for the gas to be reabsorbed and / or to escape to the outside, in the case of not being the absolutely tight seal, or simply by separating the cap from the container and allowing a faster exit of the accumulated gas inside the first inflatable part. In the event that the package is elastic, another effect can occur, consisting in that when the container is squeezed, for example by hand, it yields to the external pressure, deforming, and an internal overpressure occurs that will swell the first part inflatable cap. The opposite effect will also occur: if once the first inflatable part of the cap is swollen, the deformation is maintained and time is allowed for the overpressure inside the package to be reduced, due to an outlet of the gas contained inside from the container to the outside, and subsequently the external pressure is quickly released, for example by opening the hand, allowing the container to acquire its original shape, a depression is created inside the container that tends to suck the first inflatable part of the plug towards The inside of the container.
Estos efectos, combinados con primeras partes hinchables que sean de formas y colores atractivos, representan un reclamo de venta para el producto usuario del invento.These effects, combined with inflatable first parts that are of attractive shapes and colors, represent a sales claim for the product user of the invention.
También es posible la comercialización directa de un tapón de este tipo. Simplemente la venta de un envase elástico con un tapón de este tipo y, opcional- mente, la venta de unas pastillas que desprendan un gas al entrar en contacto con algún líquido de uso doméstico común, como pastillas efervescentes en agua, pue- den asimismo representar un juguete comercializable sin necesidad de acompañar forzosamente, como reclamo de venta, a otro producto.Direct marketing of such a plug is also possible. Simply the sale of an elastic container with a cap of this type and, optionally, the sale of tablets that give off a gas when coming into contact with a liquid of common household use, such as effervescent tablets in water, can They also represent a marketable toy without necessarily accompanying, as a sales claim, another product.
Estos tapones se pueden suministrar directamente montados en el envase o bien se pueden suministrar como un tapón adicional al tapón convencional, en cuyo caso el usuario final puede montar uno u otro tapón a voluntad. En este último caso es ventajoso si se suministran ambos tapones unidos entre sí, lo que facilita y abarata el suministro del segundo tapón y reduce el riesgo de extravío de uno de los tapones por parte del usuario.These plugs can be supplied directly mounted on the container or they can be supplied as an additional cap to the conventional cap, in which case the end user can mount one or the other cap at will. In the latter case, it is advantageous if both caps are connected together, which facilitates and reduces the supply of the second plug and reduces the risk of loss of one of the caps by the user.
Los envases disponen usualmente de una parte cilindrica, llamada el cuello del envase, y suelen contener líquidos, como por ejemplo las botellas convencionales. Aunque no por ello hay que descartar aplicaciones a otros envases, como, por ejemplo, las latas de bebidas, o los envases tipo tetra-brik.The containers usually have a cylindrical part, called the neck of the container, and usually contain liquids, such as conventional bottles. Although not for this reason, applications to other packages, such as beverage cans, or tetra-brik-type containers, must be discarded.
Estos tapones comprenden una primera parte hinchable, con un extremo abierto, y una segunda parte, con un orificio, donde la primera parte hinchable pue- de fijarse a la segunda parte, de una manera estanca y por diversas formas (pegado, soldado, mediante un dispositivo elástico, como una arandela elástica, por biin- yección, etc.).These plugs comprise a first inflatable part, with an open end, and a second part, with a hole, where the first inflatable part can be fixed to the second part, in a sealed manner and by various forms (glued, welded, by an elastic device, such as an elastic washer, by bijection, etc.).
Cuando estos tapones sustituyen totalmente al tapón convencional es necesario dotar al tapón de una tapa de cierre que cierre el orificio del extremo superior de la segunda parte. La función que debe cumplir esta tapa es la de retener la primera parte hinchable en el interior del tapón, o del envase, durante el envasado, distribución y comercialización. En el caso que el envase contenga un líquido con gas, se debe tener en cuenta que la tapa sí deberá soportar la presión del gas, que se transmitirá a través de la primera parte hinchable. Por otro lado la tapa de cierre debe ser fácilmente extraible por el usuario, mediante una operación manual. En el caso de segundas partes metálicas, se puede diseñar una tapa de cierre similar a los cierres de las latas de refrescos, donde una anilla permite estirar con el dedo de una lengüeta que cierra la lata. En el caso de segundas partes de plástico, se pueden diseñar tapas de cierre pretroqueladas. Sin embargo, estos tapones conocidos presentan algunos inconvenientes.When these plugs completely replace the conventional cap, it is necessary to provide the cap with a closure cap that closes the hole at the upper end of the second part. The function that this cover must fulfill is that of retaining the first inflatable part inside the cap, or of the container, during packaging, distribution and commercialization. In the case that the container contains a liquid with gas, it should be taken into account that the lid must withstand the pressure of the gas, which will be transmitted through the first inflatable part. On the other hand, the closing cover must be easily removable by the user, by manual operation. In the case of second metal parts, a closing lid similar to the closures of the soda cans can be designed, where a ring allows a tongue to close the can with its finger. In the case of second plastic parts, pre-locked closure caps can be designed. However, these known plugs have some drawbacks.
Así, existe el riesgo de que el líquido contenido en el envase entre en el interior de primera parte hinchable. Además, la primera parte hinchable se deshincha rápida- mente al abrir el envase, ya que la sobrepresión existente en el mismo y que hace que se mantenga hinchada la primera parte hinchable se pierde al abrir el envase.Thus, there is a risk that the liquid contained in the package enters inside the first inflatable part. In addition, the first inflatable part quickly deflates- mind when opening the container, since the overpressure existing in it and which keeps the first inflatable part swollen is lost when the container is opened.
Por otro lado, la energía acumulada en el interior de la primera parte hinchable (en forma de gas a presión) puede ser utilizada para conseguir determina- dos efectos que incrementen el atractivo del tapón.On the other hand, the energy accumulated inside the first inflatable part (in the form of pressurized gas) can be used to achieve certain effects that increase the attractiveness of the plug.
Sumario de la invenciónSummary of the invention
La invención tiene por objeto superar estos inconvenientes. Esta finalidad se consigue mediante un cierre o tapón de envase del tipo Indicado al principio caracterizado porque comprende unos medios de separación aptos para impedir el paso de un líquido contenido en dicho interior de dicho envase a dicha parte hinchable. Ello se puede conseguir, por ejemplo, al hacer que los medios de separación comprendan un filtro semipermeable, apto para permitir el paso de gases y para impedir el paso de líquidos. Otro ejemplo de realización se obtiene cuando los medios de separación comprenden un tabique estanco. En cualquiera de estos casos se consigue que el líquido contenido en el envase no entre en el interior de la primera parte hinchable.The object of the invention is to overcome these drawbacks. This purpose is achieved by a container closure or cap of the type indicated at the beginning characterized in that it comprises separation means suitable to prevent the passage of a liquid contained in said interior of said container to said inflatable part. This can be achieved, for example, by making the separation means comprise a semipermeable filter, suitable to allow the passage of gases and to prevent the passage of liquids. Another embodiment is obtained when the separation means comprise a sealed partition. In any of these cases it is achieved that the liquid contained in the package does not enter inside the first inflatable part.
Un ejemplo de estos filtros semipermeables pueden ser los filtros micróni- eos, como puede ser el filtro de microfibra de borosilicato con acabado tridimensional, comercializado bajo la marca registrada de ULTRAIR. En general, debe tenerse en cuenta que lo que se desea evitar es la entrada de elevadas cantidades de líquido en la primera parte hinchable. Este líquido, si después retorna al envase, puede causar un efecto desagradable para el consumidor. Asimismo puede ser molesto en el caso de una rotura de la primera parte hinchable, lo que, mediante un adecuado diseño puede ser minimizado, pero no puede ser controlado que dicha rotura sea causada por agentes externos. También debe tenerse en cuenta que el paso de muy pequeñas cantidades de líquido, así como el paso de vapor que posteriormente se condense en la primera parte hinchable, no resulta perjudicial para la in- vención, por lo que estas situaciones deben entenderse que están cubiertas por la presente invención, y que un filtro semipermeable que incluya el paso de vapor, e incluso de pequeñas cantidades de líquido debe considerarse incluido dentro de lo que, en la presente solicitud, se ha denominado filtro semipermeable. Preferentemente el cierre de envase comprende una válvula de retención o antirretorno. Esta válvula permite el paso del gas hacia el interior de la parte hinchable pero impide el paso del gas en sentido contrario. Ello permite que la primera parte hinchable permanezca hinchada al abrir el envase. De esta manera el efecto conseguido es de mucha mayor duración.An example of these semipermeable filters can be micronomic filters, such as the three-dimensional borosilicate microfiber filter, marketed under the ULTRAIR trademark. In general, it should be taken into account that what you want to avoid is the entry of high amounts of liquid into the first inflatable part. This liquid, if later returned to the container, can cause an unpleasant effect for the consumer. It can also be annoying in the case of a rupture of the first inflatable part, which, by means of a suitable design can be minimized, but it cannot be controlled that said rupture is caused by external agents. It should also be borne in mind that the passage of very small amounts of liquid, as well as the passage of steam that subsequently condenses on the first inflatable part, is not detrimental to the invention, so these situations should be understood to be covered by the present invention, and that a semipermeable filter that includes the passage of steam, and even of small amounts of liquid should be considered included in what, in the present application, has been called a semipermeable filter. Preferably, the container closure comprises a check or non-return valve. This valve allows the passage of the gas into the inflatable part but prevents the passage of the gas in the opposite direction. This allows the first inflatable part to remain swollen when opening the container. In this way the effect achieved is much longer.
Otra forma preferente de realización de la invención se obtiene al hacer que el tapó de envase disponga de por lo menos un orificio de salida de gas, que permita una salida del gas acumulado en el interior de la primera parte hinchable. Como se verá a continuación, esta salida del gas puede ser empleada para conseguir diversos efectos, gracias a la energía (en forma de gas a presión) acumulada en el interior de la primera parte hinchable. Este orificio u orificios de salida de gas pueden sustituir a la válvula antirretorno. El gas pasa del Interior del envase a la primera parte hinchable a través del orificio de salida de gas y se hincha la primera parte hinchable. A continuación se abre el envase y la primera parte hinchable se va deshinchando lentamente y se consigue cualquiera de los efectos que se describirán a continuación. Para ello este orificio u orificios de salida de gas deben ser pequeños, para que la primera parte hinchable se deshinche lentamente. Ello puede provocar que el hinchado de la primera parte hinchable sea más lento. Para evitarlo, se puede dotar al cierre de envase tanto de una válvula antirretorno, que permita un hinchado rápido, como de un orificio u orificios de salida de gas, que permitan un vaciado lento.Another preferred embodiment of the invention is obtained by making the container cover have at least one gas outlet opening, which allows an accumulated gas outlet inside the first inflatable part. As will be seen below, this gas outlet can be used to achieve various effects, thanks to the energy (in the form of pressurized gas) accumulated inside the first inflatable part. This orifice or gas outlet orifices can replace the non-return valve. The gas passes from the Interior of the container to the first inflatable part through the gas outlet orifice and the first inflatable part is swollen. The container is then opened and the first inflatable part slowly deflates and any of the effects described below are achieved. For this, this orifice or gas outlet holes must be small, so that the first inflatable part slowly deflates. This may cause the swelling of the first inflatable part to be slower. To avoid this, the container closure can be provided with both a non-return valve, which allows rapid inflation, as well as a gas outlet orifice, which allows slow emptying.
La energía acumulada en la primera parte hinchable puede ser empleada para hacer que el cierre de envase, una vez llena la primera parte hinchable y sacado el cierre del envase, gire sobre sí mismo. Para ello se debe dotar al cierre de envase de unos medios de giro que aprovechen el gas acumulado en la primera parte hinchable. Estos medios de giro pueden ser, por ejemplo, el propio orificio u orificios de salida de gas, que pueden estar dispuestos de tal manera que generen un par de fuerzas respecto de un eje de giro, que usualmente coincidirá substan- cialmente con un eje vertical que define el cuello del envase. De esta manera, al depositar el cierre de envase, con la primera parte hinchable hinchada, sobre una superficie (preferentemente lisa y horizontal), el par de fuerzas generado por las corrientes de gas salientes a través de los orificios de salida de gas tenderá a hacer girar el cierre de envase sobre sí mismo, alrededor de un eje de giro. Otra posible forma de emplear la energía del gas acumulado consiste en dotar al cierre de envase de unos medios de traslación que aprovechan el gas acumulado en la primera parte hinchable para desplazar el cierre de envase. Preferentemente ello se consigue mediante el o los orificios de salida de gas, que pre- sentan una geometría que establece una fuerza resultante con una componente horizontal mayor que cero. Esta componente horizontal tenderá a trasladar el cierre de envase a lo largo de una superficie sobre la que se deposite el cierre de envase con la primera parte hinchable hinchada. Lógicamente, es posible combinar los efectos de giro y de traslación. Las fuerzas generadas por la salida del gas acumulado son pequeñas, por lo que es interesante reducir al máximo el rozamiento entre el cierre de envase y la superficie sobre la que se apoya. En este sentido es interesante dotar al cierre de envase de por lo menos una faldilla que rebordee los medios de giro y/o los medios de traslación de manera que permitan la creación de un cojín de aire en la parte inferior del cierre de envase, de una manera similar al cojín de aire de los hover- craft. En los cierres de envase del tipo de rosca, las propias paredes laterales del cierre (las que contienen la rosca) pueden hacer la función de faldillas. Sin embargo estas paredes laterales son de elevado grosor y, por tanto, no son flexibles. Además, es frecuente que queden unas pequeñas irregularidades en el borde inferior, correspondientes a los puntos de anclaje de la anilla de garantía. Por ello puede ser deseable añadir una faldilla de un material muy elástico y ligero, que sea capaz de cerrar adecuadamente el espacio comprendido entre el cierre de envase y la superficie sobre la que se ha depositado el cierre, a fin de mejorar el efecto del cojín de aire. Preferentemente la faldilla tiene por lo menos un orificio lateral. Este orificio u orificios laterales puede sustituir y/o colaborar con el o los orificios de salida de gas en el desplazamiento o giro del cierre de envase. Preferentemente la faldilla tiene el perímetro lo más grande posible, a fin de maximizar el tamaño del cojín de aire. Por el mismo motivo, los orificios laterales estarían bastante alejados del eje de giro, por lo que el par que generarían sería máximo.The energy accumulated in the first inflatable part can be used to make the container closure, once the first inflatable part is filled and the container closure removed, rotate on itself. For this, the closing of the container must be provided with turning means that take advantage of the gas accumulated in the first inflatable part. These turning means can be, for example, the gas orifice itself, which can be arranged in such a way that they generate a pair of forces with respect to an axis of rotation, which usually will substantially coincide with a vertical axis. which defines the neck of the container. Thus, by depositing the container closure, with the first inflatable part swollen, on a surface (preferably smooth and horizontal), the torque generated by the outgoing gas streams through the gas outlet orifices will tend to rotate the container closure on itself, around an axis of rotation. Another possible way to use the energy of the accumulated gas is to provide the closure of the container with means of translation that take advantage of the accumulated gas in the first inflatable part to move the container closure. This is preferably achieved by means of the gas outlet orifices, which have a geometry that establishes a resulting force with a horizontal component greater than zero. This horizontal component will tend to move the container closure along a surface on which the container closure is deposited with the first swollen inflatable part. Logically, it is possible to combine the effects of rotation and translation. The forces generated by the outlet of the accumulated gas are small, so it is interesting to minimize the friction between the container closure and the surface on which it rests. In this sense it is interesting to provide the container closure with at least one skirt that bends the turning means and / or the translation means so as to allow the creation of an air cushion at the bottom of the container closure, of a similar way to the hovercraft air cushion. In thread type container closures, the side walls of the closure itself (those containing the thread) can act as skirts. However, these side walls are thick and therefore not flexible. In addition, it is common for small irregularities to remain at the lower edge, corresponding to the anchor points of the warranty ring. Therefore, it may be desirable to add a skirt of a very elastic and lightweight material, which is capable of properly closing the space between the container closure and the surface on which the closure has been deposited, in order to improve the effect of the cushion of air. Preferably the skirt has at least one side hole. This hole or side holes can replace and / or collaborate with the gas outlet orifice in the movement or rotation of the container closure. Preferably the skirt has the largest possible perimeter, in order to maximize the size of the air cushion. For the same reason, the side holes would be quite far from the axis of rotation, so the torque they would generate would be maximum.
En determinados casos, puede ser interesante que, aparte de evitar que el líquido no entre en la primera parte hinchable, evitar asimismo que el gas del interior del envase entre en la primera parte hinchable. En estos casos es necesario prever una forma alternativa de hinchar la primera parte hinchable. Para ello se puede dotar al cierre de envase de un orificio de entrada que permite introducir un gas en dicha parte superior hinchable. Este orificio de entrada es independiente del orificio de salida del envase, y no está comunicado con él. De esta manera, entre la primera parte hinchable y el orificio de salida del envase hay un tabique totalmente estanco, como ya se ha indicado anteriormente, y ni el líquido ni el gas del envase pueden pasar a la primera parte hinchable. Un ejemplo de forma de realización se obtiene al hacer que la segunda parte del cierre de envase sea un cierre totalmente convencional, por ejemplo un tapón de rosca de bebida refrescante. La parte supe- rior de este cierre está cerrada por un tabique estanco. Sobre este cierre convencional, que hace la función de la segunda parte, se monta una primera parte hinchable, que puede comprender, asimismo, los restantes elementos opcionales de la presente invención, como la válvula antirretorno, los medios de giro, los medios de traslación, etc. Preferentemente el orificio de entrada presenta un tubo de acceso por lo menos parcialmente flexible.In certain cases, it may be interesting that, apart from preventing the liquid from entering the first inflatable part, it also prevents the gas inside the package from entering the first inflatable part. In these cases it is necessary provide an alternative way to swell the first inflatable part. To this end, the container closure can be provided with an inlet opening that allows a gas to be introduced into said inflatable upper part. This inlet opening is independent of the outlet opening of the container, and is not communicated with it. Thus, between the first inflatable part and the outlet opening of the container there is a completely sealed partition, as already indicated above, and neither the liquid nor the gas in the container can pass to the first inflatable part. An exemplary embodiment is obtained by making the second part of the container closure a completely conventional closure, for example a screw cap of refreshing beverage. The upper part of this closure is closed by a sealed partition. On this conventional closure, which acts as the second part, a first inflatable part is mounted, which may also comprise the other optional elements of the present invention, such as the non-return valve, the turning means, the translation means , etc. Preferably, the inlet port has an at least partially flexible access tube.
Para evitar que la primera parte hinchable se hinche una vez montado el cierre de envase sobre el envase, por ejemplo en el caso de envases con bebidas que contengan gas (por ejemplo anhídrido carbónico, como las bebidas refrescantes, vinos espumosos, etc.), es necesario disponer de algún elemento que lo evite. En algunos casos puede ser suficiente con dotar al cierre de envase con una tapa de cierre apta para tapar el orificio del extremo superior de la segunda parte. Preferentemente esta tapa de cierre es apta para separarse del cierre con una operación manual. En otros casos puede ser recomendable que disponga de un precinto que impida el paso del gas del interior del envase al interior de la primera parte hincha- ble. Este precinto puede sustituir a la tapa de cierre, o puede ser complementario a la misma. Ventajosamente este precinto está situado en la parte interior del cierre de envase y, por tanto, es ventajoso que el precinto se saque o rompa de una forma automática. En este sentido se puede incluir un dispositivo auxiliar de cierre que perfore el precinto en el instante final de la operación de cierre del envase en el proceso de fabricación. El dispositivo auxiliar de cierre comprende un punzón (o tantos punzones como orificios de paso de gas tenga el cierre de envase) que desgarra el precinto y, simultáneamente, tapa la zona desgarrada, de manera que se mantiene la estanqueidad y, por tanto, la primera parte hinchable no se hincha. Al iniciar la apertura del envase, el punzón deja de hacer un cierre estanco, y el gas acumulado en el envase pasa rápidamente a la primera parte hinchable. De esta manera se aprovecha óptimamente el gas acumulado en el envase y que, en condi- dones normales, es evacuado al exterior. Es frecuente que los envases con tapón de rosca para bebidas carbónicas tengan tanto el filete de rosca del tapón como el filete de rosca del cuello del envase con unas discontinuidades, que tiene por objeto facilitar la evacuación del gas acumulado en el interior del envase. En el caso de un cierre de envase de acuerdo con la invención, es recomendable que la rosca no disponga de estas discontinuidades, ya que precisamente lo que interesa es que el gas acumulado pase al interior de la primera parte hinchable y no que salga al exterior.To prevent the first inflatable part from swelling once the container closure is mounted on the container, for example in the case of containers with beverages containing gas (for example carbon dioxide, such as soft drinks, sparkling wines, etc.), It is necessary to have some element to avoid it. In some cases it may be sufficient to provide the closure of the container with a closure lid suitable for covering the hole of the upper end of the second part. Preferably, this closure lid is suitable for separating from the closure with a manual operation. In other cases it may be advisable to have a seal that prevents the passage of gas from inside the container into the first inflatable part. This seal may replace the closure cap, or it may be complementary thereto. Advantageously, this seal is located inside the container closure and, therefore, it is advantageous for the seal to be removed or broken automatically. In this sense, an auxiliary closing device can be included that pierces the seal at the final moment of the closing operation of the container in the manufacturing process. The auxiliary closing device comprises a punch (or as many punches as gas passage holes have the container closure) that tears the seal and, simultaneously, covers the torn area, so that maintains tightness and, therefore, the first inflatable part does not swell. When opening the container, the punch stops making a tight seal, and the gas accumulated in the container quickly passes to the first inflatable part. In this way the gas accumulated in the container is optimally used and, under normal conditions, is evacuated to the outside. It is common for containers with screw caps for carbonated beverages to have both the screw thread of the cap and the thread fillet of the neck of the container with discontinuities, which is intended to facilitate the evacuation of the accumulated gas inside the container. In the case of a container closure according to the invention, it is recommended that the thread does not have these discontinuities, since precisely what is of interest is that the accumulated gas passes inside the first inflatable part and not out .
Otra forma de conseguir una apertura automática del precinto se puede conseguir, por ejemplo, incluyendo un dispositivo de rasgado que adopta una posi- ción de rasgado durante la apertura de dicho cierre de envase y una posición plegada durante el cierre de dicho envase. En este caso, el dispositivo de rasgado puede incluir una lámina cortante o perforante inclinada de tal manera que, al cerrar el cierre, el movimiento relativo entre la lámina y el precinto es con un ángulo tal que la lámina queda doblada sin cortar o perforar el precinto. Sin embargo, al abrir el cierre, el extremo cortante o perforante de la lámina tiende a desgarrar el precinto, consiguiéndose el mismo efecto que en el caso anterior.Another way of achieving an automatic opening of the seal can be achieved, for example, by including a tearing device that adopts a tearing position during the opening of said container closure and a folded position during the closure of said container. In this case, the tearing device can include an inclined cutting or perforating sheet such that, when closing the closure, the relative movement between the sheet and the seal is at an angle such that the sheet is bent without cutting or perforating the seal. However, when opening the closure, the cutting or piercing end of the sheet tends to tear the seal, achieving the same effect as in the previous case.
Tanto el dispositivo auxiliar de cierre como el dispositivo de rasgado pueden ser unas piezas independientes que se intercalan entre el cuello del envase y el cierre de envase, como pueden ser parte del cuello del envase, lo que requiere la fabricación de envases específicamente de acuerdo con la invención. La elección de una u otra alternativa es indiferente desde el punto de vista de la invención.Both the auxiliary closing device and the tearing device can be independent pieces that are sandwiched between the neck of the container and the container closure, as they can be part of the neck of the container, which requires the manufacture of packages specifically in accordance with the invention. The choice of one or the other alternative is indifferent from the point of view of the invention.
Otra forma de incrementar el efecto comercial del cierre de envase de acuerdo con la invención consiste en incluir por lo menos un elemento arrojadizo apto para ser expulsado del cierre de envase al hincharse la primera parte hincha- ble. Este elemento arrojadizo puede ser cualquiera que sea compatible con la invención. Así, puede ser un pequeño obsequio, o también puede ser un objeto u objetos cuya función sea conseguir un efecto vistoso, como fragmentos de papel o de materiales plásticos o metálicos ("confeti", serpentinas, etc.). Ventajosamente la primera parte hinchable es apta para alojarse, en estado deshinchado, en el interior del cuello del envase o en el interior de dicho cierre de envase.Another way of increasing the commercial effect of the container closure according to the invention is to include at least one throwing element suitable for being ejected from the container closure when the first inflatable part swells. This throwing element may be any that is compatible with the invention. Thus, it can be a small gift, or it can also be an object or objects whose function is to achieve a colorful effect, such as fragments of paper or plastic or metal materials ("confetti", streamers, etc.). Advantageously, the first inflatable part is suitable to be housed, in a deflated state, inside the neck of the container or inside said container closure.
El cierre de envase puede substituir al tapón de cierre convencional o puede ser suministrado unido con el tapón de cierre convencional.The container closure may replace the conventional closure cap or may be supplied together with the conventional closure cap.
También es ventajoso incluir un dispositivo apto para generar sonidos con el paso del gas.It is also advantageous to include a device capable of generating sounds with the passage of gas.
Finalmente es asimismo posible combinar la presente invención con una pluralidad de las alternativas descritas en el documento ES U9900951 , citado ante- riormente.Finally, it is also possible to combine the present invention with a plurality of the alternatives described in ES U9900951, cited above.

En la Figura 1 se muestra un cierre de envase apto para ser montado en el orificio de salida roscado habitual de una pluralidad de botellas. El cierre tiene una primera parte hinchable 1 y una segunda parte 3 apta para fijarse en el orificio de salida-de la botella. El cierre presenta una junta de estanqueidad 5 que facilita el cierre estanco de la botella. Adicionalmente el cierre dispone de unos medios de separación 7 que impiden el paso del líquido contenido en la botella a la primera parte hinchable 1. En este caso los medios de separación 7 son un filtro semiper- meable 8 de ULTRAIR, del tipo indicado anteriormente. La primera parte hinchable 1 está unida a la segunda parte 3 a lo largo de un paso de comunicación 9 por cualquier medio convencional conocido, como pueden ser adhesivado, termosolda- do, fijado mediante dispositivos elásticos, inyectado por biinyección.A container closure suitable for being mounted in the usual threaded outlet port of a plurality of bottles is shown in Figure 1. The closure has a first inflatable part 1 and a second part 3 suitable to be fixed in the outlet hole of the bottle. The closure has a seal 5 that facilitates the tight closure of the bottle. Additionally, the closure has separation means 7 that prevent the passage of the liquid contained in the bottle to the first inflatable part 1. In this case the separation means 7 is a semipermeable filter 8 of ULTRAIR, of the type indicated above. The first inflatable part 1 is connected to the second part 3 along a communication passage 9 by any known conventional means, such as they can be adhesive, heat-welded, fixed by elastic devices, injected by bijection.
El cierre de la Figura 1 dispone, adicionalmente, de una válvula de retención o antirretorno 11. De esta manera el gas a presión acumulado en el interior del envase pasa a través del filtro semipermeable 8 y a través de la válvula antirretorno 11 hinchando la primera parte hinchable 1. A continuación es posible sacar el cierre del envase y la primera parte hinchable 1 permanece hinchada gracias a que la válvula antirretorno 11 impide la salida del gas. En la Figura 2 se muestra otro cierre de envase de acuerdo con la invención. En este caso la segunda parte 3 dispone de dos orificios de salida de gas 13, que en el presente ejemplo se han mostrado como incorporados en un componente adicional pero que podrían estar integrados directamente en la segunda parte 3. En este caso la primera parte hinchable 1 se hincha gracias al gas que pasa tanto por la válvula antirretorno 11 como por los orificios de salida de gas 13. En este caso se ha dispuesto que el filtro semipermeable 8 esté por encima de la válvula antirretorno 11 y de los orificios de salida de gas 13 evitando así la entrada de líquido en la primera parte hinchable 1.The closure of Figure 1 additionally has a non-return or check valve 11. In this way the gas under pressure accumulated inside the container passes through the semipermeable filter 8 and through the non-return valve 11 swelling the first part inflatable 1. It is then possible to remove the closure of the container and the first inflatable part 1 remains swollen thanks to the non-return valve 11 preventing the gas from escaping. Another container closure according to the invention is shown in Figure 2. In this case the second part 3 has two gas outlet holes 13, which in the present example have been shown as being incorporated in an additional component but which could be integrated directly in the second part 3. In this case the first inflatable part 1 swells thanks to the gas that passes through both the non-return valve 11 and through the gas outlet orifices 13. In this case it has been arranged that the semipermeable filter 8 is above the non-return valve 11 and the outlet orifices of gas 13 thus preventing the entry of liquid into the first inflatable part 1.
Una vez hinchada la primera parte hinchable 1 se puede sacar el cierre del envase, tras lo cual la primera parte hinchable 1 se irá deshinchando lentamente al salir el gas a través de los orificios de salida de gas 13. Ambos orificios de salida de gas 13 están dispuestos de tal manera que la salida del gas se realiza en sentidos opuestos, creando así un par de fuerzas que tiende a hacer girar al cierre. De esta manera los orificios de salida de gas 13 hacen la función de medios de giro. Adicionalmente, si se coloca el cierre sobre una superficie substancialmente lisa y horizontal, el gas evacuado a través de los orificios de salida de gas 13 genera una ligera sobrepresión en el espacio 15 comprendido entre el interior del cierre y dicha superficie. Esta sobrepresión tiende a elevar el cierre por encima de la superficie, reduciendo así el rozamiento y facilitando el giro del cierre. En este sentido puede ser ventajoso añadirle al cierre unas faldillas 17 flexibles que mejoran la estanquei- dad del espacio 15 y por tanto incrementan el efecto del cojín de aire que se forma en el interior del espacio 15. La existencia de la válvula antirretorno 11 no es imprescindible para la invención reflejada en la figura 2, ya que la primera parte hinchable 1 podría hincharse recibiendo el gas únicamente a través de los orificios de salida de gas 13. Sin embargo los orificios de salida de gas 13 deben ser pequeños para evitar que la salida de gas sea demasiado rápida. Ello puede provocar que el llenado de la pri- mera parte hinchable 1 también excesivamente lento, lo que podría mejorarse mediante la adición de la válvula antirretorno 11.Once the first inflatable part 1 is swollen, the container closure can be removed, after which the first inflatable part 1 will slowly deflate when the gas exits through the gas exit holes 13. Both gas exit holes 13 they are arranged in such a way that the gas outlet is carried out in opposite directions, thus creating a pair of forces that tends to rotate the closure. This The gas outlet orifices 13 act as a means of rotation. Additionally, if the closure is placed on a substantially smooth and horizontal surface, the gas evacuated through the gas outlet orifices 13 generates a slight overpressure in the space 15 between the interior of the closure and said surface. This overpressure tends to raise the closure above the surface, thereby reducing friction and facilitating the rotation of the closure. In this sense it can be advantageous to add flexible skirts 17 to the closure that improve the tightness of the space 15 and therefore increase the effect of the air cushion that is formed inside the space 15. The existence of the non-return valve 11 does not it is essential for the invention reflected in Figure 2, since the first inflatable part 1 could swell by receiving the gas only through the gas outlet holes 13. However the gas outlet holes 13 must be small to prevent the gas outlet is too fast. This can cause the first inflatable part 1 to be filled too excessively slowly, which could be improved by adding the non-return valve 11.
Asimismo, en la Figura 2 se ha representado que los orificios de salida de gas 13 tienen un primer tramo vertical descendente y un segundo tramo horizontal, siendo estos segundos tramos los que discurren en sentidos opuestos para cada orificio de salida de gas 13. Sin embargo son posibles múltiples geometrías alternativas. Así por ejemplo, se podría hacer que los orificios de salida de gas 13 fuesen unos conductos rectos pero inclinados respecto del eje de giro, que usualmente coincidirá con el eje definido por la rosca del cierre y del cuello del envase.Likewise, in Figure 2 it has been shown that the gas outlet orifices 13 have a first downward vertical section and a second horizontal section, these second sections being those that run in opposite directions for each gas outlet orifice 13. However Multiple alternative geometries are possible. Thus, for example, the gas outlet orifices 13 could be made to be straight but inclined conduits with respect to the axis of rotation, which will usually coincide with the axis defined by the thread of the closure and the neck of the container.
En la figura 3 se muestra otro ejemplo de realización, en el que la primera parte hinchable 1 queda atrapada entre las paredes del paso de comunicación 9 y un componente adicional que dispone de un orificio de salida de gas 13. El cierre dispone asimismo de un filtro semipermeable 8 y dispone también de un precinto 19. Este precinto 19 tapa el paso de comunicación 9 y permite evitar que la primera parte hinchable 1 se hinche ante del momento deseado, como por ejemplo durante la etapa de llenado y cerrado de la botella en la fábrica o durante el transporte. Para que se hinche la primera parte hinchable 1 , debe retirarse o rasgarse el precinto 19. Ello puede ser realizado manualmente (abriendo el cierre, sacando el precinto 19 y volviendo a poner el cierre en la botella) o bien puede conseguirse de una forma automática, como se describirá a continuación.Figure 3 shows another embodiment, in which the first inflatable part 1 is trapped between the walls of the communication passage 9 and an additional component that has a gas outlet orifice 13. The closure also has a semipermeable filter 8 and also has a seal 19. This seal 19 covers the communication passage 9 and makes it possible to prevent the first inflatable part 1 from swelling at the desired time, such as during the filling and closing stage of the bottle in Factory or during transportation. In order for the first inflatable part 1 to swell, the seal 19 must be removed or torn. This can be done manually (by opening the closure, removing the seal 19 and putting the closure back in the bottle) or it can be achieved automatically, as will be described below.
Una forma de realizar el rasgado del precinto 19 automáticamente puede conseguirse, por ejemplo, mediante un dispositivo el mostrado en la figura 7. El cuello de la botella dispone en su punto medio de un punzón 21 y de una junta de estanqueidad adicional 23 soportados por unos brazos 25 que lo unen al cuello de la botella, conformando un dispositivo auxiliar de cierre 26. Este dispositivo auxiliar de cierre 26 puede ser una parte integral de la botella o puede ser una pieza adicional que queda alojada en el cuello de la botella por cualquier medio conocido, por ejemplo por alguno de los descritos en el documento ES U9900951. De esta manera al cerrar la botella con el cierre durante el proceso de fabricación en la planta embotelladora, el cierre se empieza a enroscar sobre el cuello de la botella con el precinto 19 intacto, por lo que no se hincha la primera parte hinchable 1. En el instante final de cerrado de la botella, es decir en el límite de carrera del cierre, el punzón 21 perfora el precinto 19 alojándose en el orificio de salida de gas 13. Prácticamente en el mismo instante la junta de estanqueidad adicional 23 cierra herméticamente la zona del precinto 19 perforada, por lo que se alcanza un cierre estanco del cierre. En el momento de abrir la botella, al inicio del desenroscado del cierre se establece rápidamente una comunicación fluida a través del precinto 19 rasgado y del orificio de salida de gas 13. De esta manera se aprovecha de una forma óptima la sobrepresión existente en la botella, que sirve para llenar la primera parte hinchable 1 en lugar de escaparse hacia el exterior, como sucede habitualmente. Ello se puede optimizar eligiendo adecuadamente los materiales y grosores de las dos juntas de estanqueidad 5 y 23. En la figura 4 se aprecia como en la parte superior del cierre hay una tapaOne way of automatically tearing the seal 19 can be achieved, for example, by means of a device shown in Figure 7. The neck of the bottle has at its midpoint a punch 21 and an additional seal 23 supported by arms 25 that connect it to the neck of the bottle, forming an auxiliary closing device 26. This auxiliary closing device 26 can be an integral part of the bottle or it can be an additional piece that is housed in the neck of the bottle by any known means, for example by any of those described in document ES U9900951. In this way, when the bottle is closed with the closure during the manufacturing process in the bottling plant, the closure begins to screw on the neck of the bottle with the seal 19 intact, so that the first inflatable part 1 does not swell. At the final closing moment of the bottle, that is to say in the limit of the closing stroke, the punch 21 pierces the seal 19 being housed in the gas outlet orifice 13. Practically at the same instant the additional sealing gasket 23 closes tightly the area of the perforated seal 19, whereby a tight seal closure is reached. At the time of opening the bottle, at the beginning of unscrewing the closure, fluid communication is quickly established through the torn seal 19 and the gas outlet orifice 13. In this way the overpressure existing in the bottle is optimally utilized. , which serves to fill the first inflatable part 1 instead of escaping outwards, as usually happens. This can be optimized by suitably choosing the materials and thicknesses of the two sealing gaskets 5 and 23. In Figure 4 it can be seen that in the upper part of the closure there is a cover
25 que cierra el paso de comunicación 9 de manera que durante el transporte y almacenamiento de la botella, la primera parte hinchable 1 queda alojada en el interior del paso de comunicación 9 y el orificio que comunica el paso de comunicación 9 con el exterior queda cerrado mediante la tapa 25. Adicionalmente en la figura 4 se puede observar que es posible añadir unos orificios laterales 27 en la faldilla 17 que colaboren o substituyan el efecto de giro o traslación que pueden ser realizados por los orificios de salida de gas 13. Es decir, por ejemplo en el caso de que se desee que el cierre gire, es posible disponer los orificios de salida de gas 3 de manera que realicen un par de fuerzas, como ya se ha descrito anteriormente y, adicionalmente, que haya unos orificios laterales 27 que realicen asimismo un par de fuerzas que incremente el efecto de giro. Alternativamente se puede hacer que los orificios de salida de gas 13 no realicen ningún "efecto especial", y que el par de fuerzas sea realizado únicamente por los orificios laterales 27.25 which closes the communication passage 9 so that during transport and storage of the bottle, the first inflatable part 1 is housed inside the communication passage 9 and the hole communicating the communication passage 9 with the outside is closed by means of the cover 25. Additionally, in figure 4 it can be seen that it is possible to add lateral holes 27 in the skirt 17 that collaborate or replace the rotation or translation effect that can be performed by the gas outlet holes 13. That is , for example, in the event that the closure is desired to rotate, it is possible to arrange the gas outlet orifices 3 so as to make a pair of forces, as already described above and, additionally, that there are lateral holes 27 that also make a pair of forces that increase the turning effect. Alternatively, it is possible for the gas outlet orifices 13 to have no "special effect", and for the torque to be made only by the side orifices 27.
En las figuras se ha mostrado siempre soluciones en las que los orificios de salida de gas 13 y/o los orificios laterales 27 realizan pares de fuerza. Sin embargo también es posible realizar los orificios de salida de gas 13 y/o los orificios laterales 27 con unas geometrías que, en lugar de realizar un par de fuerzas, realicen una fuerza resultante que tienda a desplazar el cierre configurando así unos medios de translación. Evidentemente es también posible conseguir efectos combinados.The figures have always shown solutions in which the gas outlet orifices 13 and / or the side orifices 27 make torques. However, it is also possible to make the gas outlet orifices 13 and / or the side orifices 27 with geometries that, instead of making a couple of forces, make a resulting force that tends to move the closure thus configuring translation means . Obviously it is also possible to achieve combined effects.
Los orificios laterales 27 pueden estar dispuestos tanto en las faldillas 17 como directamente en la pared lateral exterior del cierre. En la figura 5 se aprecia otra forma de realización de la invención. En este caso la segunda parte 3 presenta un tabique estanco 29 que separa totalmente el interior de la botella de la primera parte hinchable 1. En este caso la segunda parte 3 cierra la botella de un modo convencional. La segunda parte 3 dispone en su parte superior de un tramo roscado 31 sobre el que puede montarse la primera parte hinchable 1. En este caso la primera parte hinchable 1 presenta una geometría y unos componentes muy similares a la totalidad del cierre de los ejemplos anteriores. La segunda parte 3 dispone además de un orificio de entrada 33 que permite introducir un gas, a través de un tubo de acceso 35 hasta el interior de la primera parte hinchable 1. El tubo de acceso 35 es preferiblemente flexible y permite un hinchado manual de la primera parte hinchable 1. El tubo de acceso 35 está preferentemente protegido adecuadamente para evitar que llegue al usuario sucio o deteriorado.The side holes 27 may be arranged both on the skirts 17 and directly on the outer side wall of the closure. Another embodiment of the invention can be seen in Figure 5. In this case the second part 3 has a sealed partition 29 that completely separates the inside of the bottle from the first inflatable part 1. In this case the second part 3 closes the bottle in a conventional manner. The second part 3 has in its upper part a threaded section 31 on which the first inflatable part 1 can be mounted. In this case the first inflatable part 1 has a geometry and components very similar to the entire closure of the previous examples. . The second part 3 also has an inlet port 33 which allows a gas to be introduced, through an access tube 35 to the inside of the first inflatable part 1. The access tube 35 is preferably flexible and allows manual inflation of the first inflatable part 1. The access tube 35 is preferably adequately protected to prevent it from reaching the dirty or damaged user.
En la figura 6 se muestra un cierre de envase de acuerdo con la invención con la primera parte hinchable 1 replegada en el paso de comunicación 9 y con la tapa 25 cerrada. Adicionalmente hay un elemento arrojadizo 37 representado esquemáticamente, que en la práctica, puede ser una pluralidad de objetos como pequeños obsequios, fragmentos de papel o de materiales plásticos o metálicos ("confeti", serpentinas, etc.). En la figura 8 se muestra un ejemplo de dispositivo de rasgado 39 del precinto 19. En este caso se ha representado que el dispositivo de rasgado 39 es una pieza independiente que se fija en el interior del cuello de botella por cualquier medio conocido, pero podría ser asimismo una parte integral del cuello de botella, co- mo en el caso del dispositivo auxiliar de cierre 26. El dispositivo de rasgado 39 presenta por lo menos una lengüeta 41 flexible (en el ejemplo mostrado en la figura 8 hay dos lengüetas 41). En este caso, al cerrar el cierre sobre el cuello de botella, las lengüetas 41 están orientadas de tal manera que el precinto 19 tiende a apretarlas hacia abajo, siendo el movimiento del precinto 19 en el sentido de rotación que va del punto de unión de las lengüetas 41 con la estructura de soporte del dispositivo de rasgado 39 al extremo libre de las lengüetas 41. Sin embargo, al abrir la botella, el movimiento es en sentido contrario por lo que el extremo libre de las lengüetas 41 tiende a clavarse en el precinto 19 y/o a rasgarlo estableciéndose la comunicación fluida entre el interior del envase y la primera parte hinchable 1. Even- tualmente es posible aumentar esta tendencia a clavarse a base de introducir algunas rugosidades o irregularidades en el precinto 19. A container closure according to the invention is shown in Figure 6 with the first inflatable part 1 folded in the communication passage 9 and with the lid 25 closed. Additionally there is a thrown element 37 schematically represented, which in practice, can be a plurality of objects such as small gifts, fragments of paper or plastic or metal materials ("confetti", streamers, etc.). An example of a tearing device 39 of the seal 19 is shown in Figure 8. In this case it has been shown that the tearing device 39 is an independent part that is fixed inside the bottleneck by any known means, but could being also an integral part of the bottleneck, as in the case of the auxiliary closing device 26. The tearing device 39 has at least one flexible tongue 41 (in the example shown in Figure 8 there are two tabs 41) . In this case, when closing the closure on the bottleneck, the tabs 41 are oriented such that the seal 19 tends to tighten them down, the movement of the seal 19 being in the direction of rotation that goes from the point of attachment of the tabs 41 with the support structure of the tearing device 39 at the free end of the tabs 41. However, when opening the bottle, the movement is in the opposite direction so that the free end of the tabs 41 tends to dig into the seal 19 and / or tear it by establishing the fluid communication between the inside of the container and the first inflatable part 1. It is possible to increase this tendency to stick by introducing some roughnesses or irregularities in the seal 19.
