Definitions

  • the present invention relates to a removable cover, in particular for Beverage cans or other food-containing cans with which the Protect the surface of the can lid from dirt before opening can be.
  • Food and beverage cans are often 2 or 3 piece metal cans crimped lid.
  • the food or drink packed in such cans are in many cases consumed straight from the can after opening. this applies especially for beverage cans with a pull tab.
  • Using the pull tab creates an opening in the can lid through which the beverage is removed, and very often through direct drinking.
  • the mouth of the consumer comes here in contact with the lid surface.
  • part of the Tear tab pushed into the inside of the can, where it is washed by the drink. It is therefore almost inevitable that impurities on the lid in the drink and also come into contact with the mouth of the drinker when drinking directly.
  • Tolerance is waning as hygiene awareness increases in society towards this state; it is therefore both from the need of the individual also with regard to future legal regulations to expect that one Lids exposed to contamination are no longer accepted.
  • covers are those which are shrunk onto the sealed can. For this it is necessary that already filled can to an additional operation with heating subject, with a considerable amount of mechanical effort must be driven. In addition, not all drinks or foods can tolerate such Heat treatment. Both solutions also have another disadvantage together: Covering a beverage lid in the beverage bottling company is over hygienic view always questionable, because in such companies a very high Air humidity and the associated high bacterial load. In all rooms that are not atmospherically separated from the bottling plant, everyone forms Surface of any object, but especially on a relatively cool surface Surfaces, immediately a film of moisture that contains microorganisms.
  • the object of the present invention is to provide lids for in Cans to be used in the food sector with a cover as Hygiene protections are provided, the cover being simple, without additional Effort such as the use of additional machines or operations in the bottling plant and without the risk of additional microbial contamination between the lid and Cover can be applied and causes little waste.
  • the lids for which the present invention is suitable are preferably lids with Flanged edge and the shape is not limited, provided that it is compared to the Have the lid mirror at least slightly rolled up the flanged edge.
  • the lid material can be metal, e.g. Aluminum or steel, but the invention is not limited to lids made of certain materials. Conveniently they have Lid also a channel running around the lid mirror, also as a "core" referred to the outside on the so-called core slope in the curl transforms. Beverage can lids are often designed in this way.
  • a can lid is proposed as claimed in claim 1. At least this is the lid mirror of the contour following the lid on the outside with a plastically deformable material covered, at least up to the area of the core and possibly up to Area in which the raised edge of the lid merges with the curl or its forms the highest point, is sufficient and is attached to the lid there.
  • the cover is sufficient the lid mirror up to the raised area, which is in the curl passes, possibly up to their highest point. If the lid has a gutter, that's enough the cover beyond the lid mirror at least into the area of Core, preferably down to the area between the core and the curl, the so-called Core slope, in. It preferably follows the contour of the core over its bottom away to a height that is at or above the level of the lid level.
  • the cover is not to the highest point the roll-on is sufficient, but ends below it, as this complicates the Closing the can be avoided.
  • the cover is preferably connected to the lid in its outer region.
  • the connection can, for example, by gluing with an adhesive or Sealing with the help of a sealing wax or welding, depending on used material.
  • the attachment only outside the Cover mirror takes place, for example by ring-shaped sealing in the area below the curl, but preferably in the area of the core, if there is one is present, and very particularly preferably in its outer area within the core slope (i.e. in the area between the core and the curl) at a height that exceeds the level of the lid mirror.
  • Such an embodiment has the advantage that when removing the cover from the center of the cover mirror (e.g.
  • Glue or seal so that the connection between the Cover and the lid can be easily removed, e.g. with only weak Sealing power to seal. This can be used to prevent residues of the The cover remains in the area of the gutter or the edge of the flange.
  • the Cover made of the plastically deformable material, as already mentioned, in the area of the cover mirror a tear-off tab, which is integrally connected to the cover or can be glued, sealed or otherwise applied. So that the Tear open and tear off cover particularly cheaply.
  • This tear tab is related to its shape is not limited, but care must be taken that it follows. Do not apply the cover on the lid over the roller or even the Flared edge extends. Because in such a case she would clinch and / or flanging detected by the corresponding roles of the capping head and be damaged or destroyed; in the worst case, even the flaring process be affected. Therefore, the tab preferably has a shape that does not have the Lid mirror protrudes; if necessary, it can also be folded in the cover mirror lie.
  • the tear-off tab can be attached centrally to the cover mirror; However, it is preferred that it is arranged asymmetrically near the core, since during the tear-off process in this case the force is introduced at a point where the mechanical Voltage becomes very large, so that the detaching process can take place particularly easily. If, on the other hand, the tab is applied centrally on the cover mirror, this is the case with Detaching process results in a rotationally symmetrical force distribution, that is, a clear one "more stable" configuration, in which the force applied to the attachment between cover and lid acts, acts evenly in all places, although for the purposes of Invention is sufficient, but not particularly cheap.
  • the plastically deformable material should preferably be so stable that it Withstands the forces required to remove the film from the lid.
  • a tear-resistant thin, flat material is expedient used, e.g. a thin film made of a metal like aluminum, a plastic or a natural material. Mixtures of these can of course also be used Materials or a film laminated from various such materials are used become.
  • the thickness of the film is advantageously chosen depending on the material, it can e.g. are in the range of 20 to 500 ⁇ m.
  • This Material can be of natural origin or synthetic. Are suitable for example naturally occurring polymers such as cellulose or polymers of substances occurring in nature.
  • the plastically deformable material can be preformed, for example deep drawn and then applied to the lid and then glued or sealed become.
  • the invention is not limited to such a manufacturing process; the Material could also be shaped in other ways and on the lid be applied.
  • the lid according to the invention can in the filling and closing process as a uncovered lids can be used. This means that the invention is realized without the machines used for filling and closing would have to be replaced or supplemented with additional machines.
  • Figure 1 shows an embodiment of the invention as a sectional drawing. You can see that Part of a cover 4 with a curl belonging to the flange, one encircling core 2 and a cover mirror 3.
  • the cover consists of a thin film 5, which the contour of the lid from the lid mirror over the core up in follows the area of rolling and has a tear-off tab 6.
  • the place of Attachment 7 is represented by a circle. It is in this configuration in the beginning of the roll-up area.
  • the attachment can, however, on any Location of the core, in the area between the core and the curl (core slope) and on the Rolling up to its highest point can be realized.
  • Figure 2 shows another embodiment of the invention, it is also one Sectional drawing of part of the lid according to the invention, the state is shown, which when lifting the cover 5 by means of the tear-off tab 6 sets, just before the cover comes off the lid.
  • this Design is the location of the attachment 7 in the core slope, however above the level of the lid mirror 3.
