Abstract

Abstract Inner wrappings (20) for cigarette groups (21) or the like, as part of the pack, should be as effectively sealed against aroma and moisture losses as possible. For this purpose, side tabs (34, 35) for forming side walls (27, 28) are connected to one another in a sealed manner in the region of overlapping strips (37, 38), to form a bonding strip (36). The bonding strip (36) extends over part of the height or length of the inner wrapping (20), so that an opening flap (29) can be freed from the inner wrapping (20).

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 288 words
Cuboid pack for cigarettes, with an outer wrapping consisting of thin cardboard, and having an inner wrapping surrounding a cigarette group, comprising: (a) an inner wrapping (20) made out of a tinfoil blank; (b) the inner wrapping (20) being provided with a pull-off opening flap (29) which extends in an upper region of a longitudinal front wall (23), in a front sub-region of an upper end wall (26) and in an upper, front sub-region of narrow side walls (27, 28) of the inner wrapping (20); (c) in the narrow side walls (27, 28) of the inner wrapping (20), each side wall comprising side tabs (34, 35) bonded to one another along overlapping strips (37, 38) of the side tabs only up to an unbonded portion (39) adjacent to the opening flap, to form a sealed bonding strip (36) preventing aroma and moisture losses; (d) the overlapping strips (37, 38) being bonded to one another in a fin-fold along their inner faces turned towards one another; (e) in the region of the opening flap (29), the overlapping strips (37, 38) lying with their inner faces against each other, in the unbonded portion (39); (f) each bonding strip (36), together with its adjacent unbonded portion (39), being folded around until it comes up against a corresponding one of the side walls (27, 28); and (g) a transverse connecting cut (42) in each front side tab adjoining a transverse punching (40) in the front wall (23), each connecting cut delimiting the opening flap (29) in each of the front side tabs (35) in front of the overlapping strips (37, 38), so that the overlapping strips extend uninterrupted over the longitudinal length of the inner wrapping (20) below said opening flap (29).
Claim 2
Dependent Claim 288 words
Cuboid pack for cigarettes, with an outer wrapping consisting of thin cardboard, and having an inner wrapping surrounding a cigarette group, comprising: (a) an inner wrapping (20) made out of a tinfoil blank; (b) the inner wrapping (20) being provided with a pull-off opening flap (29) which extends in an upper region of a longitudinal front wall (23), in a front sub-region of an upper end wall (26) and in an upper, front sub-region of narrow side walls (27, 28) of the inner wrapping (20); (c) in the narrow side walls (27, 28) of the inner wrapping (20), each side wall comprising side tabs (34, 35) bonded to one another along overlapping strips (37, 38) of the side tabs only up to an unbonded portion (39) adjacent to the opening flap, to form a sealed bonding strip (36) preventing aroma and moisture losses; (d) the overlapping strips (37, 38) being bonded to one another in a fin-fold along their inner faces turned towards one another; (e) in the region of the opening flap (29), the overlapping strips (37, 38) lying with their inner faces against each other, in the unbonded portion (39); (f) each bonding strip (36), together with its adjacent unbonded portion (39), being folded around until it comes up against a corresponding one of the side walls (27, 28); and (g) a transverse connecting cut (42) in each front side tab adjoining a transverse punching (40) in the front wall (23), each connecting cut delimiting the opening flap (29) in each of the front side tabs (35) in front of the overlapping strips (37, 38), so that the overlapping strips extend uninterrupted over the longitudinal length of the inner wrapping (20) below said opening flap (29).
Claim 3
Dependent Claim 274 words
Cuboid pack for cigarettes, with an outer wrapping consisting of thin cardboard, and having an inner wrapping surrounding a cigarette group, comprising: (a) an inner wrapping (20) made out of a tinfoil blank; (b) the inner wrapping (20) being provided with a pull-off opening flap (29) which extends in an upper region of a longitudinal front wall (23), in a front sub-region of an upper end wall (26) and in an upper, front sub-region of narrow side walls (27, 28) of the inner wrapping (20); (c) in the narrow side walls (27, 28) of the inner wrapping (20), each side wall comprising side tabs (34, 35) bonded to one another along overlapping strips (37, 38) of the side tabs including a region above the lowermost point of the opening flap (29), to form a sealed bonding strip (36) preventing aroma and moisture losses; (d) the overlapping strips (37, 38) being bonded to one another in a fin-fold along their inner faces turned towards one another; (e) each bonding strip (36) being folded around until it comes up against a corresponding one of the side walls (27, 28); and a connecting cut (42) in each front side tab adjoining a transverse punching (40) in the front wall (23), each connecting cut delimiting the opening flap (29) in each of the front side tabs (35) in front of the overlapping strips (37, 38), so that the overlapping strips extend uninterrupted over the longitudinal length of the inner wrapping (20) below said opening flap (29), wherein each connecting cut (42) is directed obliquely upwards from the transverse punching in the direction of the upper end wall (26).
