Abstract (en)
[origin: WO8702011A1] 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. To open the pack the edge region (6) is gripped at the fold (3) and pulled away from the edge region (6') while releasing the seal in the region of the joining strip (7).
