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. In another version, the areas (23', 24') where the material is folded in two are produced by cutting the edges of folds (23, 24) previously formed in the packing material; the wrapper is then opened by peeling off the seals of these folded areas (23', 24').
