Abstract
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').

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
Package for packing pieces of goods, especially subdivided or subdividable packing goods having an at least approximately even surface area, with a wrapper made of one piece of flat foldable packing material and having at least two strip-shaped doubling areas, each being formed by two strip-shaped areas of the packing material connected with each other at the surface of the packing material generally facing the packing goods, to form a strip-shaped sealing zone, so that each doubling area shows an outer free edge, whereby the wrapper is opened by severing the sealing of the sealing zone of at least one of the doubling areas, characterized in that the wrapper includes two spaced strip-shaped doubling areas (2,3) at said at least approximately even surface area, that a predetermined break line (4) of the packing material is arranged in one strip-shaped packing material of each strip-shaped doubling area (2,3) within and along its strip-shaped sealing zone, and that a tearing up zone (18) of the wrapper is provided laterally defined by said break lines in said two doubling areas.
Claim 2
Dependent Claim
177 words
Package for packing pieces of goods, especially subdivided or subdividable packing goods having an at least approximately even surface area, with a wrapper made of one piece of flat foldable packing material and having at least two strip-shaped doubling areas, each being formed by two strip-shaped areas of the packing material connected with each other at the surface of the packing material generally facing the packing goods, to form a strip-shaped sealing zone, so that each doubling area shows an outer free edge, whereby the wrapper is opened by severing the sealing of the sealing zone of at least one of the doubling areas, characterized in that the wrapper includes two spaced strip-shaped doubling areas (2,3) at said at least approximately even surface area, that a predetermined break line (4) of the packing material is arranged in one strip-shaped packing material of each strip-shaped doubling area (2,3) within and along its strip-shaped sealing zone, and that a tearing up zone (18) of the wrapper is provided laterally defined by said break lines in said two doubling areas.
Claim 3
Dependent Claim
31 words
Package according to claim 1 characterized in that both doubling areas (2,3) are arranged in the vicinity of two opposing edges (14,15) of the approximately even surface area of the package.
Claim 4
Dependent Claim
35 words
Package according to claim 1, characterized in that the doubling areas (2,3) are respectively folded over in the direction away from the center of the tearing up zone and toward the surface of the package.
Claim 5
Dependent Claim
45 words
Package according to claim 3, characterized in that the layers of packing material of the folded doubling areas lying on the surface of the package are connected at least over a part of their surface with the surface of the package through gluing or sealing.
Claim 6
Dependent Claim
98 words
Package according to claim 1 characterized in that the package is a tubular bag with a longitudinal sealing seam (8, 8') and two transverse sealing seams (9, 9') defining the fins (10, 10') of the package wherein the both doubling areas (2,3) laterally enclosing the tearing up zone (18, 21) extend parallel to the longitudinal sealing seam (8, 8') and cross the sealing zone (12, 12') of at least one of the transverse sealing seams (9,9') and wherein the tearing up zone ends at the free edge (11, 11') of at least one of the fins (10, 10').
Claim 7
Dependent Claim
62 words
Package according to claim 5, characterized in that at one fin (10, 10') of the package at its free edge (11,11') the tearing up zone is ending the sealing zone (12, 12') of the transverse sealing seam (9, 9') does not approach the free fin edge (11, 11') at least in the area between the ends of both doubling area (2, 3).
Claim 8
Dependent Claim
45 words
Package according to claim 1, characterized in that the doubling areas (2,3) which include predetermined break lines (4) in the packing material for defining lateral boundaries of the tearing up zone (18) are constituted by folds of packing material at the surface of the package.
