Definitions

  • containers for drinks whether made of metal or paper, have opening devices which al­low holes of different shapes to be made in their lids. Sometimes this hole is used to pour the liquid into a clean cup, or to suck the drink through a straw. In most cases, the hole in the lid is used to drink the contents of the container resting one's lips directly on the lid.
  • This behaviour entails a serious health hazard in view of the many times the container is handled from the time it is manufactured until it is used by the cus­tomer.
  • the same drawback from a hygienic point of view occurs for other products, edible or otherwise, of which the original state of hygiene should be main­tained intact when pouring the product through preformed holes or made with any suitable instrument.
  • the purpose of this invention is to overcome this draw­back by means of a device for hygienic protection al­lowing the user, for example, to rest his lips on a clean surface, sterilised at the origin.
  • a protective layer wider than the hole through which the liquid passes is ap­plied on top of the lid of the drink container.
  • the protective layer according to the invention may be ap­plied to the lids of containers having either a pull-­off or thrust-type opening device.
  • said protective layer is applied over the lid, but it is possible to alter the described embodiment so as to apply a layer under the lid, which would become a sur­face for resting one's lips on and a working surface for pouring out the liquid.
  • removal of the protective layer may be associated with the operation for opening the hole through which the liquid passes; in other solutions, it is possible to prepare the hole through which the liquid passes under the protective layer on the lid of the container.
  • the protective layer may be applied to the lid of the con­tainer before this is fastened onto the actual con­tainer, thus reducing the manufacturing costs.
  • the protective layer may be double: in this case it may be applied even only just before the user himself opens the con­tainer: thus the upper layer will be removed and the upper surface of the underlying layer will act either as a surface for the contents of the container to flow over or as a place to rest one's lips if the contents consist of a drink.
  • Figure 1 shown the lid of a metal container equipped with a thin plate with cut edges and which can be torn off the container to create an opening by means of a pulling ring of a type already known; said thin plate with the cut edges is covered by a protective layer larger than the shape of said plate, and which is removed together with the plate.
  • Figure 2 shows, from below, the plate with the cut edges after its removal together with the protective layer.
  • Figure 3 shows the lid of the container after both said plate and the protective layer have been removed.
  • Figure 4 is a par­tial axial cross-section of the side wall, the lid of the container and the protective layer applied on top of the latter, before the container is opened.
  • Figure 5 refers to a second variant, in which the protective layer is applied to the whole lid, which may be opened in any suitable manner after removal of the protective layer; in particular, there is nothing to prevent there being a through hole in the lid of the container under the protective laye.
  • Figure 6 refers to a third variant of embodiment, ac­cording to which the container is a prism-shaped con­tainer made of waterproofed cardboard.
  • Figure 7 is a fourth variant of embodiment, applicable specifically to extruded aluminium containers and figure 8 is a partial axial cross-section of the con­tainer illustrated in figure 7.
  • Figure 9 shows in perspective a further form of embodi­ment of the invention, while figure 10 is an axial cross-section of the container shown in figure 9.
  • Figure 11 is similar to the previous figure, but refers to the container-opening phase.
  • Figures 12 and 13 show the container, seen from above, before and after it is opened.
  • 10 indicates a metal disk used to form the lid of a container for a drink.
  • the rim 11 of the disk 10 When it is applied to the top of the container, the rim 11 of the disk 10 will be folded over so that it forms a tight seam on the upper rim of the cylindrical wall 12, as shown in figure 4.
  • the disk 10 has an elongated tab 20, defined by an outline 21, cut into the disk 10 for a fraction of its thickness, so that it may be pulled away in order to create an elongated opening 22 with a shape corresponding to that of the tab 20, in order to pour out the drink.
  • a pulling ring 23 when this ring us pulled upwards, the tab 20 is gradually torn away from the disk 10 along its cut outline 21, opening the hole 22.
  • This system is known and is commonly used.
  • a protective layer 30, larger than the tab 20, is applied on top of the tab 20 having the cut outline.
  • Said protective layer may ex­tend over the whole area of the disk 10, although a circumferential extension of about 60 degrees is felt to give the user's lips sufficient hygienic protection.
  • the solution illustrated in figures 1 to 4 is par­ticularly effective, since it is possible to remove in a single operation, by pulling on the ring 23, both the tab 20 opening the lid of the container and the protec­tive layer 30 protecting that part of the lid where the user is to rest his lips.
  • the protective layer is also applied to the seamed wall 32: when the tab 20 and the protective layer 30 are applied, the latter will tear along its seamed edge 32, freeing an area of seamed edge which is protected from a hygienic point of view.
  • the protective layer may be made of various materials: a thin layer of synthetic material or plastic-coated paper may be sufficient to protect the portion of the lid in question if the tab 20 is connected to the pull­ing ring 23 and is removed together with the protective layer 30.
  • the protective layer 30 may also be made of a thin layer of metal or of an equally strong material: in this case it may be applied to the disk by light brazing or using suitable adhesives and, if so, be con­nected to the pulling ring 23.
  • the disk 10 may have, right from the start, the opening 22 which will be covered by the protective layer 30, in which case the latter will also function as a seal.
  • the area 31 underlying the protective layer 30 will have a far greater extension than the area of the opening 22.
  • the opening in the lid is made using a pressure device, rather than a pull-off device as shown in the figure, the protective layer will be fitted with a flap to be pulled.
  • the container has at least its top part and obviously the whole lid 61 covered by a protective hood 62, preferably made of synthetic material, and which has to be torn off before opening the lid, which may be done in any traditional manner.
  • a protective hood 62 preferably made of synthetic material, and which has to be torn off before opening the lid, which may be done in any traditional manner.
  • the hygienic protection ex­tends as far as the upper edge of the container.
  • the protective layer may extend over the whole surface of the container.
  • the container 70 is made preferably of plastic-­coated cardboard, and has a prism shape.
  • a protec­tive layer is applied, of the stick-on type or glued with a suitable adhesive. It covers partly the edge be­tween the lid 71 and the the side 72.
  • said protective layer covers parts of both the lid 71 and the side 72.
  • the lid On the lid 71, under the area covered by the protective layer 73, the lid has an opening 74, which is freed when the protective layer is removed.
  • the container is clearly made of extruded aluminium. This justifies the bulging outline 81 connecting the cylindrical side-wall 83 to the flat bottom 82.
  • the protective layer 84 is applied in a similar manner to the container 70 of figure 6, and takes in part of the side surface 83 and part of the surface of the lid 82, as well as a portion of the edge between the two.
  • the hole 85 which is freed when the protec­tive layer 84 is removed, may be preformed in the lid 82.
  • the type of adhesive used to connect the protective layer to the outer surface of the container is particularly important.
  • the adhesive must be of the thin-layer type, and capable of withstanding high shear stresses on its plane, but easily removable by peeling, that is to say by pulling away the protective layer in a direction perpendicular to the surface to which it is applied.
  • the container 100 of figure 9 has a protective layer 110, for example of a rectangular shape, the under sur­face of which is self-adhesive, so that it may be ap­plied, even directly by the user, to the container 100.
  • a protective layer 110 for example of a rectangular shape, the under sur­face of which is self-adhesive, so that it may be ap­plied, even directly by the user, to the container 100.
  • it is applied partly to the lid 111 and partly to the side surface 112 of the container, so as to cover the edge 113.
  • the part 121 of the protective layer 110 applied to the lid 111 covers the area of the opening 122, represented by the dashed line.
  • the protective layer 110 is formed by two sheets, 210 and 211, the lower one being preferably equipped with an opening 213, shaped ap­proximately like the outline of the opening 122 in the lid 111.
  • the upper sheet 211 has no cuts or openings of any kind in it.
  • the two sheets are held together by a thin layer of adhesive which allows them to be easily separated by the user, freeing the undoubtedly clean upper surface of the lower sheet.
  • the presence of the opening 213 above the future opening 122 in the lid means that it is possible to remove the upper sheet 211 by removing the segment of lid corresponding to the opening 213 by means, for example, of the pulling ring 123.
  • removal of the upper sheet 211 may be achieved by preparing on it a narrow protruding edge for gripping it, not shown in the figure but easily made. If the container does not have a preformed opening but has to be holed, for example with a pointed object, then the bottom sheet 210 will not require a preformed opening 213.
  • the protective layer is applied by the manufacturer, it can be equipped with one or more seals to guarantee its integrity. If the protective layer is applied by the user before use, the seal may be applied to the packaging in which the protective layer is supplied.
