<p>For a packaging (1), consistant of an internal bag (2) containing for example a product preserved under vacuum, of an external container and of a small frame with integral lid (6) made of plastic material, an improved sticking system is described, which renders both said bag and the external container integral with the small frame itself. The adoption is envisaged of reliefs on the lower wall of the flange (10) of the small frame, and of branched fins (30) arranged in the peripheral groove (12) of said small frame, into which the edge of the external container is inserted, in order to increase the surface area for adhesion, promote the distribution of the glue and to create barriers to the passage of air for the purpose of improving the hermetic sealing of the lid during the use of the packaging. The upper edge of the external container can also have a differently shaped configuration in order to improve adhesion.</p> |
