DETAILED DESCRIPTION OF THE INVENTION

With reference to the illustrated drawings, the present utility model refers to a “SAFETY AND PROTECTION SEAL ARRANGEMENT FOR FOODSTUFF AND BEVERAGE PACKING” and, more particularly, refers to a heat-shrinkable seal (1) applied to the opening or mouthpiece (B) of a packing (E), preferably for prompt consumption foodstuff.

According to the present utility model, heat-shrinkable seal (1) comprises a tubular portion (2) of heat-shrinkable material, sized such as to entirely or partially involve the packing, more precisely mouthpiece (B) of the packing, which tubular portion (2), after being positioned around the packing, is heat-shrinked defining a top collar (3) flat and parallel to cap (T) of packing (E), defining an annular support surface for the welding (4) of a disk-shaped seal (5).

The heat-shrinkable material from which tubular band (2) is made is preferably of the PVC-, PET-, BOPP-, Nylon-type or the like, being it provided with or without a ribbon (6) to aid in extracting seal (1), or further with a partially perforated line acting in the same way as the ribbon.

The top closing disk (5) can be made from several materials, depending on the welding (4) operation, which can be through heat or a self-adhesive substrate applied to collar (3) formed on band (2) after the heat-shrinking thereof around packing (E); the preferred materials applied to disk (5) are cellulose, aluminum, BOPP, PVC, Polystyrene or the like.

Both band (2) and disk (5) may be made as two- or more-layered laminate substrates.

The present heat-shrinkable seal can easily be incorporated to the productive process of any canned product, wherein, advantageously, the constructive features thereof permit that the same be applied to any type of packing enclosure, be it a double-seamed (R), screw-capped, aluminum-capped can or the like, where the cost added to the final product is negligible and the benefit to the consumer is immediate.
