Abstract: A lid for closing containers includes an at least two-layered composite assembly. A layer facing the container seals against a container edge and forms an opening by layer separation, for removing contents. The layers have a continuous construction without weakening lines. The layer facing the container is made mainly of a plastic having an intrinsic tearing resistance being lower in the region of the opening than its adhesion to the layer facing away from the container in a remaining region and an adhesion to the container edge being greater at least in the region of an opening aid than to the other layer. The plastic adheres so strongly to the outer layer in the region of the opening that a region corresponding to the opening is torn out upon opening and a remaining layer of the lid facing the container continues to adhere to the container edge by sealing action.

Abstract: Method for the production of a compound foil as an endless strip, the compound foil to be processed in the form of rectangular blanks covering a width of the endless strip characterized in that two different foil strips, of which a first strip contains an aluminum foil (4) or a paper are drawn through a lamination machine with tractive forces to overcome friction losses in the machine, these tractive forces producing different elongations in said two different foil strips, that one of the endless strips is provided at one side surface with a binding agent over a connecting surface, which consists of several partial areas (3, 13) separated from each other, that the two strips are connected to each other while the both strips being elastically stretched to different elongations as the strips are drawn through the lamination machine whereby after the two foil strips coming back again to their non-stretched starting state, that surfaces of the blanks each have one central area and two margin areas (9, 12) borderi

Abstract: In an easy-to-open chocolate package, the wrapper has two areas (2, 3,23', 24') where the packing material is folded in two, made of two layers of packing material sealed together by their inner side, lying on an essentially even upper surface of the wrapper and laterally enclosing a tearing up zone (18, 26) of the wrapper, so that when the package is torn open the wrapper is opened up in these areas. In an embodiment as a cylindrical bag, the tearing up zones (18, 26) extend until the free edge (11, 11') of a fin (10, 10') by which the tearing up zone (18, 26) is held when tearing the package open. These areas (2, 3) where the packing material is folded in two preferably take the form of folds, one flank of which is provided with a break line (4) of the packing material, along which the material is torn when the package is opened.

Abstract: Gas-sealed pack for receiving pieces of a material such as chocolate tablettes. It consists of an envelope (9) of a flat and foldable material, having two edge regions (6, 6') inside which is located a detachable joining strip (7) to provide a sealed closure, preferably by cold sealing. These edge regions are folded back onto the upper surface of the envelope (9). The outside of the edge region (6'), which is applied to the top surface of the envelope (9), is linked at least on part of its surface with the surface of the envelope (9) preferably by means of a hot melting adhesive. The other edge region (6), which is not connected to the upper surface of the envelope (9), does not extend as far as the joining strip (7). A fold (3) is preferably arranged on this edge. The inner surfaces of the envelope are joined by cold sealing. Thus the pack is preferably designed in a tubular shape.
