This object is achieved by a protective cover for the hygiene protection of food packaging elements, comprising the features of claim 1.

The invention has for its further object to provide a beverage can with a protective cover as a hygiene protection, so that when opening the beverage can contamination of the can contents is avoided and the risk for a user with bacteria, viruses or other adhering to the beverage can impurities when drinking in contact avoided or greatly reduced.

The above object is achieved by a beverage can with a protective cover as a hygiene protection, it comprises features of claim 4.

The protective cover according to the invention serves for hygiene protection of a packaging element for food. According to a possible embodiment, the protective cover consists of a first film layer and a second film layer. The first film layer and the second film layer are both detachably connected to each other. The first film layer is provided with an adhesive layer for permanently attaching the protective cover to the packaging element. The first film layer further carries an adhesive layer, via which the second film layer is detachably connected to the first film layer. The adhesive layer itself contains a germ-free and food-not influencing surface.

According to a possible embodiment of the invention, the adhesive layer itself may contain a food-grade and highly volatile disinfectant. As a result, the germ-free and the food non-influencing surface of the adhesive layer is provided.

This has the advantage that, after detachment of the second film layer, the adhesive layer remains on the first film layer, and a substantially germ-free surface is then made available by the rapidly evaporating disinfectant. With this germ-free surface then the food can be brought into contact in the container. The packaging element for the food is thus germ-free, regardless of the previously prevailing storage and transport conditions for the packaged food.

The disinfectant is embedded in the adhesive layer, which volatilizes after removal of the second film layer. Thereby, taste deterioration of the food with which the packaging member comes in contact can be avoided. Preferably, the disinfectant is a volatile and tasteless alcohol.

The beverage can according to the invention is provided with a protective cover as a hygiene protection. The beverage can comprises a lid and a wall adjoining the lid. The lid has an opening mechanism in which when opening the beverage can a part of the lid dips into the liquid and releases a drinking opening. The protective cover consists of a first foil layer and a second foil layer. The protective cover is in one piece and can be permanently connected to the lid in the area around the drinking opening and in an area of the wall with an adhesive layer of the first film layer. An adhesive layer releasably connecting the first film layer to the second film layer contains a germ-free surface that does not affect the food.

The first film layer carries the adhesive layer, via which the second film layer is detachably connected to the first film layer. The adhesive layer contains a suitable and easily volatile disinfectant for the beverage in the beverage can. The one-piece protective cover on the beverage can has the advantage that the area (lid and wall area) of the beverage can is covered by the protective cover, which is covered when drinking from the beverage can with the mouth of a user. The area covered by the protective cover essentially corresponds to the generally accepted mouth size of an adult human being. After detachment of the second film layer, the disinfectant evaporates or volatilizes, resulting in a substantially germ-free and non-food-influencing surface of the first film layer. Thus it can be guaranteed that the surface of the first film layer is germ-free irrespective of the storage and transport conditions. The rate of volatilization of the disinfectant should preferably be within 0.5 - 2 seconds, so that there is no long wait for a user to drink from the beverage can.

When opening the beverage can, a part of the lid of the beverage can dips into the drink. In order to facilitate the separation of the first film layer in the region of the drinking opening, the first film layer around the drinking opening is provided with a perforation. When opening the beverage can by means of the opening mechanism, the predetermined breaking points of the first film layer tear and the part of the lid dips into the liquid with the first film layer.

The protective cover can be designed such that it surrounds the drinking opening in the lid of the beverage can in the form of a sector. The protective cover is so flexible that it extends from the lid of the beverage can on an upper edge of the beverage can on the wall of the beverage can and all over the whole area.

The one-piece protective cover on the lid of the beverage can and the wall of the beverage can is dimensioned such that the mouth of a user comes to rest on the adhesive layer of the first film layer after detached second film layer and when using the beverage can.

Film intended to reduce the risk of adverse effects on food (drinks) to reduce or completely eliminate.

The protective cover according to the invention fully meets the requirements for hygiene in the manufacture, treatment and marketing of Food (Food Hygiene Regulation - LMHV). It is therefore an adverse effect: a disgusting or other impairment of the proper hygienic condition of the drink, such as microorganisms, contaminants, weathering, odors, temperatures, gases, vapors, smoke, aerosols, animal pests, human and animal excretions and waste , Wastewater, cleaning agents, pesticides, veterinary drugs, biocidal products or inappropriate treatment and preparation processes excluded or at least significantly reduced.

The invention has for its object to provide a protective cover for the hygiene protection of packaging elements for food, so that when opening the packaging for the food contamination of the food in the package is avoided.
