Description

  The present invention relates to a water-absorbing heat-insulating sheet and a container with a sheet, and more particularly to a technique suitable for insulating a container for containing beverages and foods or preventing moisture such as condensation from dripping on the side of the container.

  Conventionally, most beverage containers used for beer and other beverages that are favored in a cold state are aluminum cans with high thermal conductivity. Thus, when it is refrigerated by making it an aluminum can with high heat conductivity, the merit that it can cool efficiently is acquired. On the other hand, after taking out from the refrigerator, there is a demerit that the beer in the can is heated quickly by the heat transmitted from the indoor air or the hand holding the can, until the user finishes drinking beer and beverages There was a problem that the taste of beer and cold drinks was impaired.

  In addition, in canned beverages such as beer that are kept cold, when they are taken out of the refrigerated case and come into contact with outside air, the surface of the can container surface is often lower than the dew point temperature of the outside air, so condensation often occurs. Particularly in the summer, the temperature difference between the surface of the can container and the outside air temperature is large and the relative humidity is high, so that in most cases, the dew condensation phenomenon occurs and many water droplets adhere to the surface of the can. For this reason, the hand holding the can gets wet due to water droplets of condensation, or the table on which the can is placed gets wet, and further, the wrapping paper is infiltrated by condensation and causes damage or deformation of the wrapping paper. There was also a problem.

  In addition, for cans of beverage containers used for other beverages such as tea, coffee, tea, etc., which are preferred in the hot state, the majority are made of metal with high thermal conductivity, and when heating, The merit that it can be heated efficiently is obtained. On the other hand, it is too hot to be gripped directly by hand, or after taking it out of the heat storage, the coffee in the can cools rapidly due to the heat transmitted from the indoor air or the hand holding the can, and the user makes tea. There is a problem that the texture of the hot beverage is impaired before the beverage is finished.

  Various ideas have been made to prevent such inconvenience. For example, if you wrap a heat shield or insulation sheet around the outer periphery of a container such as a can and grasp the container through the wrapped part, you can drink the contents even if the container is too hot or too cold (Patent Document 1, Patent Document 2).

  Also in paper cup containers as beverages such as coffee, soup, miso soup and soup, noodles such as ramen, yakisoba and udon, or cooked food containers that are heated and eaten with a microwave oven such as pilaf and gratin. Insulating measures are taken to protect the fingers gripping the container from the heat of the contents during eating and drinking. For example, a method in which a heat-insulating foam plastic sheet is provided around a cup is known.

  Furthermore, although this method is excellent in heat insulation when containing a container such as hot water, the foamed plastic sheet becomes very hot when heated in a microwave oven. In the microwave heating, the contents are heated and the cup container and the surrounding foamed plastic sheet are also heated. Further, it is considered that the foamed plastic sheet is in contact with the cup-shaped container, so that the heat is not easily cooled.

  In this way, the method of using foamed resin as the material makes it difficult to print beautifully on the surface, has high calorie burn, has problems in incineration and disposal, and further raises consumers' environmental awareness. Due to the accompanying changes in consumption behavior, there are demands for easily disposable and easily incinerated containers and heat insulating sheets instead of foamed resins.

Furthermore, there are foods that require a so-called hot water draining operation, such as fried noodles, tsukemen, spaghetti, etc., when the hot water once poured is discarded.
Conventionally, heat-insulating materials such as expanded polystyrene resin have been widely used as materials for containers poured with hot water. However, in recent years, paper containers have been used instead of plastics for the purpose of environmental friendliness and material cost reduction. Has been used (Patent Document 3). When the paper container is made of a single layer of paper, the heat insulating property is inferior to that of the foamed plastic container.

  However, since the heat insulating sheets described in Patent Documents 1 and 2 are relatively thin, heat insulation is not sufficient. As a result, containers with hot beverages are often too hot to hold comfortably. In addition, the outer surface of a container containing a cold drink often has moisture, which makes it difficult to hold the container and wets the hand or table of the person holding it. In addition, since the heat insulation performance is insufficient, there is a problem that the cold drink is likely to be warm and the hot drink is quickly cooled.

  Furthermore, since such a heat insulating sheet covers the entire outer surface of the container, all the prints are hidden and the advertisement part cannot be seen. In particular, for certain products such as canned coffee, it is not preferable that the purchaser is often obsessed with the brand logo, and the outer surface of the can is not visible. In order to cope with such a state, transparent heat insulating sheets have been made, but generally they are made of conductive materials as raw materials, and since the conductive materials are in close contact with containers, The effectiveness of is almost lost. On the other hand, since the heat insulating sheet exhibiting a sufficient heat insulating effect is too bulky, there is a problem that it takes up a small storage space such as a convenience store or cannot be stored in a vending machine.

The present invention has been made in view of the above circumstances, and intends to achieve the following object.
1. It is possible to provide a water-absorbing and heat-insulating sheet capable of absorbing moisture such as condensation and sufficient heat insulation, and a beverage container provided with the same.
2. Exhibit sufficient adiabatic water absorption effect without impairing design.
3. To achieve both thickness reduction and heat insulation performance.
4). Suppress the volume increase as a container and have little effect.
5). Stimulates euphoria and has excellent functionality.

The water-absorbing heat insulating sheet of the present invention has a pasting portion and a folding portion that is connected to the pasting portion and folded.
The said subject was solved by at least one part consisting of a foamable paper material.
In this invention, it is preferable that the length which extended the said folding part folded is set longer than the said affixing part.
The present invention can include a lid that is attached to the pasting portion and covers the folded folded portion.
Further, in the present invention, it is possible to adopt means in which the folding part and the lid part are made of the foamable paper material of a single sheet and are attached to the attaching part.
The pasting portion has a back surface to which the water-absorbing heat insulating sheet is pasted and a surface to which the folding portion and the lid portion are pasted, and a base end of the folding portion is pasted to the surface of the pasting portion. In addition, it is possible to cover the folded portion where the tip of the lid portion is detachably attached to the surface of the attaching portion so as to be peeled off.
The water absorption heat insulation sheet of this invention can have a printing display part.
In the container with a sheet of the present invention, the water-absorbing heat insulating sheet according to any one of the above can be attached to the side surface.
Moreover, it is preferable that the container with a sheet | seat of this invention is made into the length which the said folding part and the said cover part make a round of the said side surface, when the said water absorption heat insulation sheet is expanded.
The container with a sheet of the present invention can be a beverage can.

The water-absorbing heat insulating sheet of the present invention has a pasting portion and a folding portion that is connected to the pasting portion and folded.
At least a part of it is made of foamable paper, which has sufficient heat insulation properties. When affixed to a container, the container is held by insulating the fingers it holds regardless of the temperature inside the container. It becomes possible. At the same time, the foamable paper material is hygroscopic and water-absorbing, so it can absorb condensation on the surface of the container or moisture dripping on the surface when it is attached to the container. It is possible to prevent these moisture from dripping.

Here, the foamable paper material has a high porosity of about 69% or more and a density in the range of about 0.3 to 0.01 g / cm ³ , more preferably a density of 0.25 to 0.05 g / cm. ^This means a sheet-like paper material in the range of ³ . Since the basis weight depends on the thickness dimension of the sheet-like paper material, the density is important in the present invention. If the density of the paper material is higher than the above range, it is not preferable because the amount of air contained is small and may not exhibit sufficient heat insulation. If the density of the paper material is lower than the above range, the sheet This is not preferable because the strength of the film cannot be maintained, and it may break during the manufacturing process such as printing or during use.

  In the present invention, the display area formed on the side surface of the container when folded and attached to the side surface of the container by setting the length of the folded folded part to be longer than that of the pasting part. Is not hidden more than necessary, and the design on the side of the container is not hindered. Also, by sticking to the side of the container and extending the folded part, it is possible to cover a wider part of the side of the container than the pasted area. In the case of a low-temperature container, it is possible to exhibit water absorption in a wide region.

  The present invention has a lid portion that is attached to the affixing portion and covers the folded portion that is folded, so that the folding portion can be expanded for the first time by opening the lid portion. Therefore, when the water-absorbing heat insulating sheet is attached to the side surface of the container, even if the container is stored in a vending machine or the like, it is possible to prevent the folding part from being inadvertently expanded. In addition, when the folding part is extended, a surface different from the surface (outer side surface) of the lid part can be presented, so information such as advertisements, recipes, explanations, or whales can be displayed as a display part (printing display part) Provided on the back side (inner side surface) of the folding part and the lid part, in the state where the folding part is folded and stored, the display part is concealed, and the display part is visible only after the container purchaser opens the lid part. State.

  Further, in the present invention, the folding portion and the lid portion are made of the foamable paper material of a sheet, and are attached to the attaching portion, so that the folding portion and the lid portion are most By elongating, the length of the foamable paper material can be effectively applied. For example, on the side surface of the container, the entire periphery can be covered with the foamable paper material. In addition, since the water-absorbing and heat-insulating sheet can be formed simply by folding and attaching the folded portion and the lid portion of the sheet to the attaching portion, the manufacturing process is reduced and the manufacturing cost is reduced. be able to.

  The pasting portion has a back surface to which the water-absorbing heat insulating sheet is pasted and a surface to which the folding portion and the lid portion are pasted, and a base end of the folding portion is pasted to the surface of the pasting portion. In addition to covering the folded part, the tip of the lid part being detachably attached to the surface of the attaching part and being folded, a display area can be provided in addition to the attached part and expanded. By re-adhering the tip of the lid and the extended tip of the folded part, it becomes easy for the water-absorbing and heat-insulating sheet to cover the entire circumference of the container side and not to be detached from the side of the container.

  Since the water-absorbing heat insulating sheet of the present invention has the print display section, it can display information different from the side surface of the container to be pasted, and make this information visible. Thereby, compared with the display amount of only the container side surface, the amount of information to be displayed can be significantly increased.

  The container with a sheet of the present invention can be easily gripped by hand even when storing high-temperature contents with excellent heat insulation, by adhering the water-absorbing heat-insulating sheet described above to the side surface. In addition, it is possible to prevent water droplets of dew condensation or spilled spills from dripping down to the bottom even when hot water having excellent water absorption and low temperature is stored. At the same time, it is possible to display a large amount of information compared to the area of the side surface without impairing the design of the side surface of the container. This can also be achieved without increasing the volume of the container more than necessary.

  In the container with a sheet of the present invention, when the water-absorbing and heat-insulating sheet is expanded, the folding part and the lid part have a length that makes a round of the side surface, so that the water-absorbing and heat-insulating sheet covers the entire circumference of the container side surface. Therefore, it is possible to improve stability when the container is held by hand, and moisture does not hang down to the bottom.

  The container with a sheet of the present invention is a can for beverages, and thus exhibits heat insulation performance, water absorption performance, and display function without disturbing the design of the side of the can corresponding to hot beverages or cool beverages. It becomes possible.

  According to the present invention, in a state where the area of the container is folded and reduced, the design of the container side surface is not hindered, and the heat insulation performance, the water absorption performance, and the display function are exhibited. It is possible to provide an effect that it is possible to provide a water-absorbing and heat-insulating sheet and a container with the water-absorbing and heat-insulating sheet, which can be provided with drooping, whales, and the like as display areas to exhibit emanating properties.

It is a water-absorbing heat insulating sheet.

  As shown in FIGS. 1 to 3, the water-absorbing heat insulating sheet 10 according to the present embodiment includes a pasting portion 11, a folding portion 12 that is connected to the pasting portion 11 and folded, and a lid portion 13 that covers the folding portion 12. And having.

As shown in FIG. 4, the affixing portion 11 is made of a foamable paper material, and contains air 112 inside the foaming portion 111, which is in a so-called faint state and has thermal conductivity. It is low.
Here, the foamable paper material has a high porosity of about 69% or more and a density in the range of about 0.3 to 0.01 g / cm ³ , more preferably a density of 0.25 to 0.05 g / cm. ^This means a sheet-like paper material in the range of ³ . If the density of the paper material is higher than the above range, it is not preferable because the amount of air contained is small and may not exhibit sufficient heat insulation and water absorption, and the density of the paper material is lower than the above range. In addition, the strength cannot be maintained, and it is not preferable because it may break during the manufacturing process such as printing or at the time of use.

In addition, the thickness dimension in a foamable paper material shall be the range of about 0.35-1.0 mm, More preferably, it can be set to about 0.5-0.75 mm. In this case, the basis weight is about 100 to 150 g / m ² , but what is important for heat insulation and water absorption is the density, and the basis weight has an appropriate numerical range depending on the thickness dimension set according to the use state. It is possible to change. Examples of such foamable paper materials include Watlite (registered trademark) manufactured by Oji Specialty Paper Co., Ltd.

  Similarly, both the folding portion 12 and the lid portion 13 are made of foamable paper material. The folding part 12 and the lid part 13 are formed by folding a sheet of foamed paper of equal width into multiple pieces in the folding direction according to ruled lines (folding lines) extending in the width direction. Yes. Specifically, as shown in FIG. 3, the folding part 12 and the lid part 13 are in a state in which the lid part 13, the folding part 12 a, the folding part 12 b, and the folding part 12 c are successively connected in the length direction from the right. Is formed.

  The length of the lid portion 13 in the folding direction is set to be larger than the lengths of the folding portion 12a, the folding portion 12b, and the folding portion 12c in the folding direction. When the folding part 12 and the lid part 13 are folded, the lid part 13 is set so as to cover the folding part 12 so that the surface of the folding part 12 cannot be seen from the outside as shown in FIG. .

  The folding portion 12 and the lid portion 13 are pasted by a laminating portion 14 provided near the boundary between the folding portion 12 and the lid portion 13, specifically, at the base end portion of the folding portion 12 a adjacent to the lid portion 13. It is connected to the surface of the attaching part 11. The bonding portion 14 is provided over the entire length in the width direction of the folding portion 12a, and is provided over the entire length in the width direction that is the right end portion of the bonding portion 11 in the drawing.

  An adhesive portion 16 is provided on the distal end side of the lid portion 13 to adhere the distal end of the lid portion 13 covering the folding portion 12 to the attaching portion 11. The adhesive part 16 can be re-sealed and re-adhered by an easy peeling part 15 described later. Moreover, the adhesion part 16 is located in the inner surface side facing the bonding part 11 surface, when the folding part 12 and the cover part 13 are folded. When the folding part 12 and the lid part 13 are stretched and expanded, the inner surface of the lid part 13 provided with the adhesion part 16 faces the same outward direction as the surface of the affixing part 11 provided with the bonding part 14. Position.

The tip of the lid 13 covering the folding portion 12 can be re-sealed at the end in the width direction, which is the end on the opposite side of the attaching portion 14 in the attaching portion 11, that is, the left end of the attaching portion 11 in the drawing. An easy peeling part 15 for bonding is provided. The easy peeling portion 15 is obtained by performing surface treatment such as varnish application on the surface of the foamable paper material.
In the lid portion 13, an easily peelable portion 16 b similar to the easily peelable portion 15 is formed at a position closer to the base end than the adhesive portion 16. The easy peeling portion 16b is for preventing the adhesive from sticking out to the folding portion 12 side when the adhesive protrudes and is folded in the adhesive application process to be the bonding portion 16.

  As shown in FIG. 4, a paste portion 11 a is formed on the entire surface of the pasting portion 11 so that the water-absorbing and heat insulating sheet 10 can be pasted on a container C or the like described later. In a state before being attached to the container C, as shown in FIGS. 1 to 3, the entire surface of the glue portion 11a can be covered with the release paper 10a.

  A display unit (print display unit) 17 is formed on the surface of the pasting unit 11, the front and back surfaces of the folding unit 12, and the front and back surfaces of the lid unit 13 by means of printing or the like. It can be an area for display. In FIG. 3, the display unit 17 is shown only on the inner surface of the lid 13 and the folding unit 12c. However, this is an example, and the arrangement of the display unit 17 is not limited to this configuration.

  As shown in FIG. 1, the water-absorbing and heat insulating sheet 10 of the present embodiment has the folding portion 12 folded and covered with the lid portion 13, and the adhesive portion 16 is adhered to the easily peelable portion 15. The front end of this is bonded to the bonding portion 11 and the folding portion 12 is concealed by the lid portion 13. The release paper 10a can be attached to the glue part 11a.

In this state, as shown in FIG. 5, the release paper 10 a can be peeled off and the water-absorbing heat insulating sheet 10 can be attached to the side surface of the container C.
Next, as shown in FIG. 2, the bonding portion 16 is peeled from the easy peeling portion 15, and the tip of the lid portion 13 is separated from the bonding portion 11. Then, the folding part 12 opens from the folded state.

Next, as shown in FIG. 3, the front end of the lid portion 13 is opened to a state further separated from the bonding portion 11. Then, the folding part 12 is opened from the folded state, and the folded part is further extended.
Then, the folding part 12 and the cover part 13 can be made into the state extended to the dimension larger in an opening direction than the sticking part 11, and was extended | stretched straightly. Compared to the area of the bonded portion 11 in the folded state as described above, the expanded area of the water-absorbing and heat-insulating sheet 10 is used for heat insulation and water absorption during gripping.

  In order to manufacture the water-absorbing heat insulating sheet 10 of the present embodiment, a sheet of foamable paper material serving as a folding portion 12 and a lid portion 13 that are continuous in the width direction on which predetermined characters and designs are printed is supplied. A varnish or the like is applied to the region that becomes the easy peeling portion 16b with a coater or the like in the direction, the folding portion 12 and the lid portion 13 are folded from the ruled line, and then an adhesive that becomes the bonding portion 16 is applied. At the same time, a sheet of foamable paper material sheet to be the pasting part 11 continuous in the width direction on which predetermined characters and designs are printed is supplied, and the paste part 11a is formed on the entire back surface, and then attached to the release paper 10a. Then, a varnish or the like is applied to the surface of the surface to be the easily peelable portion 15 with a coater or the like in the width direction. Thereafter, an adhesive material to be the bonding portion 14 is applied, and the sheet is bonded to the folded sheet 12 to be the folded portion 12 and the lid portion 13 and cut to have a predetermined width dimension. Thus, the water-absorbing heat insulating sheet 10 in a state of being attached to the release paper 10a is completed.

  In addition, the water-absorbing and heat-insulating sheet 10 can also be used as an advertising label by printing the display portion 17 aimed at the eye catching effect and information disclosure on the surface of the water-absorbing and heat-insulating sheet 10, particularly the outer surface of the lid portion 13. is there. In that case, it can also be set as the structure which provided the non-foaming layer used as a coating layer in the outer side surface of the cover part 13, and this makes it possible to raise the smoothness of a surface further and to perform high-definition printing. The printing effect can be enhanced.

  As shown in FIG. 5, the container with sheet C of the present embodiment is a beverage can container of a type having a substantially uniform diameter over the entire length in the axial direction, and a water-absorbing and heat-insulating sheet 10 folded on the side surface is attached. It has been.

  In this state, the container with a sheet C has almost no change in volume and outer shape due to the adhered water-absorbing and heat-insulating sheet 10, and therefore, similar to the container C without adhering the water-absorbing and heat-insulating sheet 10, stores such as convenience stores, or It can be sold in vending machines.

  In the container C with a sheet, when the water-absorbing and heat insulating sheet 10 is stretched as described above, the water-absorbing and heat insulating sheet 10 goes around the body of the container C as shown in FIG. And the front-end | tip part of the folding part 12c extended from the circumferential direction opposite side can be made to contact the adhesion part 16 which faced the radial direction outer side of the container C from the further outer side. Since the folding part 12c is not provided with an easy peeling part, the bonding part 16 and the folding part 12c are bonded relatively firmly. Thereby, the state where the water absorption heat insulation sheet 10 was fixed in the state which circled the circumference | surroundings of the container trunk | drum can be maintained.

  Assume that the sheet-equipped container C is, for example, an aluminum can with high thermal conductivity, and cool beer and other cold drinks are stored. In this case, even after taking out the container C with the sheet from the refrigerator, the side of the container C is covered with the stretched water-absorbing heat insulating sheet 10, so that the beer in the can is heated by the heat transmitted from the indoor air or the hand holding the can. It is possible to prevent the flavor of beer and beverages from being impaired before the user finishes drinking beer and beverages.

  Further, in the container C with a sheet, which is a can that contains beer or the like and is kept cool, the relative humidity is high and the temperature difference between the surface of the container C and the outside air temperature is large. Even when the surface of the container C having a lower temperature is taken out from the refrigerated case and is exposed to the outside air to cause dew condensation, and a large number of water droplets adhere to the surface of the container C, the side of the container C is stretched by the stretched water-absorbing heat insulating sheet 10. By covering, water droplets and the like of dew condensation can be absorbed by this water-absorbing heat insulating sheet 10 on the entire circumference of the container C. For this reason, the hand holding the container C is prevented from getting wet due to water droplets of condensation, the table on which the container C is placed is prevented from getting wet, and the wrapping paper packaging the container C due to condensation is infiltrated. It is possible to prevent the wrapping paper from being damaged or deformed.

  Similarly, when the sheet-equipped container C is made of a metal can having high thermal conductivity and used for other hot beverages such as tea, coffee, tea, etc., in which a hot state is preferred, water-absorbing and heat-insulating The sheet 10 is stretched to cover the entire circumference of the container C with the water-absorbing heat-insulating sheet 10 whose area is larger than that of the folded state. After being taken out of the heat storage, the hot beverage in the container C is rapidly cooled by the heat transmitted from the hand holding the room air or the container C, and the beverage is consumed until the user finishes drinking the beverage such as tea. It becomes possible to reduce that the texture of this is impaired.

The container C with a sheet according to the present embodiment can be folded and affixed with the water-absorbing and heat-insulating sheet 10 without impairing the design of the surface of the container C, and is stretched to place the water-absorbing and heat-insulating sheet 10 on the outer periphery of the container C. By fixing in a wound state and exhibiting heat insulation in the entire covered area, if the container is grasped through this wound portion, the contents can be drunk even if the container is too hot or too cold. At the same time, it is possible to prevent moisture from being absorbed and dripping down to the bottom of the container C when water droplets of dew condensation, spilled spills, etc. hang down.
Therefore, heat insulation and water absorption can be exhibited simultaneously.

  Furthermore, when it is set as the storefront display state which stuck the water-absorbing heat insulation sheet 10 folded, since the water-absorption heat insulation sheet 10 has covered only a part of the container C for drinks, it is goods other than the part to which the water absorption heat insulation sheet 10 has adhered. If the logo / catch copy is printed, the beverage container C can be promoted without concealing it, and additional sales promotion without impairing the design can be performed.

  In the water-absorbing heat insulating sheet 10 of the present embodiment, the folding portion 12 is folded in three, but the state is not limited as long as the folding portion 12 is folded and covered with the lid portion 13. It is also possible to increase from a state without the folding part 12 to a state where a large number of folding parts 12 of about 10 pieces are connected in the folding direction. Moreover, according to the dimension of the circumferential direction of the container C, the dimension of the bending direction can be set so that it can fix and make a round. Or the folding part 12 can also be set as the structure affixed on the affixing part 11 as a foaming paper material different from the cover part 13. FIG.

Furthermore, in the water-absorbing heat insulating sheet 10 of the present embodiment, the affixing portion 1, the folding portion 12, and the lid portion 13 have uniform width direction dimensions. However, as shown in FIG. The bent pieces 12e and 12d can be connected to each other. The connecting position of the folded pieces 12e and 12d may be any of the folding parts 12a to 12c.
Thereby, the area of the display part 17 provided in the folding part 12 can be increased, the amount of display information to be displayed on the display part 17 can be increased, and, for example, information with high shooting characteristics such as a lottery is printed. Moreover, by making the display unit 17 inside the folding, it is possible to reliably conceal the display information formed on the internal display unit 17 before opening.

Furthermore, the folded part such as the folded part 12e located on the lower side in the width direction is formed as a contour shape larger than the entire bottom part of the container C, and the shape is set so as to reach the bottom part of the container C. It can also be laid on the bottom of the container C to make it like a coaster. Thereby, it becomes possible to prevent the liquid dripping to the bottom part of the container C.
Further, the container C may be a screw cap type having a reduced diameter of the drinking mouth.

Hereinafter, 2nd Embodiment of the water absorption heat insulation sheet | seat and container with a sheet | seat based on this invention is described based on drawing.
FIG. 8 is a perspective view showing the container with a sheet in the present embodiment. In this embodiment, the difference from the first embodiment described above is the point related to the use of the container, and the other first embodiment described above. The same reference numerals are given to the configurations corresponding to the forms, and the description thereof is omitted.

  The container C1 with a sheet in this embodiment is a cooked food that is heated and eaten with the container in a microwave, such as beverages such as coffee, soup, miso soup, and soup, ramen, fried noodles, udon, or pilaf, gratin. The folded water-absorbing heat insulating sheet 10 is affixed to the side surface of the container C1 so as to be stretched in the circumferential direction.
