Abstract

A cigarette pack in the form of a sealing pack consisting of an inner pack and an outer pack in the form of a hinge-lid box. An opening aid of the inner pack is provided with a removal opening which is formed as an open recess as a result of punching during the production of a blank for the inner pack, in particular in the region of a continuous material web. Said removal opening, which is free right from the start, is closed by a closure tab which is able to be opened and closed multiple times on account of a corresponding glue connection. The closure tab is preferably connected permanently to the inside of a lid front wall of the outer pack by means of an actuating tab.

First claim

What is claimed is:

1. A pack for cigarettes ( 10 ) or other smoking articles having an outer pack ( 25 ), in the form of a hinge-lid pack with a box part ( 26 ) and lid ( 27 ), and having an inner pack in the form of a sealing block with a blank ( 12 ) of material which surrounds a cigarette group, wherein the inner pack ( 11 ) comprises an opening aid ( 18 ) in an end-face region of an inner front wall ( 13 ) of the inner pack ( 11 ) and at least in a part of a region of an inner end wall ( 17 ), wherein the opening aid ( 18 ) comprises a closure means in the form of a closure tab ( 20 ) which is produced from a separate blank and which is arranged on the outside of the inner pack ( 11 ) and is fastened on the inner pack ( 11 ) by means of releasable adhesion and for opening the inner pack ( 11 ) is pulled at least in part away from the inner pack ( 11 ) and, as a result, exposes a removal opening ( 19 ) at least in part, wherein:
the inner pack ( 11 ) comprises a removal opening ( 19 ) as a free opening, the removal opening ( 19 ) being produced during production of the inner pack ( 11 );
b) the closure tab ( 20 ) covers the removal opening ( 19 ) completely and on all sides in a closed position, with an overlapping edge or overlapping strip ( 21 , 22 , 23 ) which extends all around the removal opening ( 19 );
c) the closure tab ( 20 ) is free of adhesives in the region of the removal opening ( 19 ), wherein the adhesive-free region of the closure tab ( 20 ) is slightly greater than the region of the removal opening ( 19 ) and runs all around and surrounds the removal opening ( 19 );
d) the closure tab ( 20 ) comprises a glue-free actuating tab ( 24 ) in a region adjacent to the inner front wall ( 13 ) in the closed position; and
e) the means of releasable adhesion are strips of releasable adhesive located on the closure tab ( 20 ) in regions directly adjacent to the adhesive-free region of the closure tab ( 20 ).

2. The pack as claimed in claim 1 , wherein to create the open removal opening ( 19 ) a blank ( 12 ) or a material web ( 36 ) for producing the blank ( 12 ) is provided with the removal opening ( 19 ), wherein an opening lug ( 35 ) is completely removed or remains part of the blank ( 12 ) by means of an edge-side connection and as a result of folding over is moved out of the region of the removal opening ( 19 ).

3. The pack as claimed in claim 2 , wherein the opening lug ( 35 ), which is connected to the blank ( 12 ), is folded against a wall of the inner pack ( 11 ), against an inside of an inner rear wall ( 14 ), wherein the opening lug ( 35 ) is fixed in the fold position.

4. The pack as claimed in claim 1 , wherein the means for releasable adhesion are glue fields applied to the overlapping edge or overlapping strip ( 21 , 22 , 23 ) on the inside of the closure tab ( 20 ) for connection of the closure tab ( 20 ) to the inner pack ( 11 ), and comprise regions of varying intensity or strength of adhesion, in such a manner that, when the closure tab ( 20 ) is actuated, the closure tab ( 20 ) includes a bonding zone in the form of a transverse strip ( 22 ) with a degree of bonding, then a longitudinal strip ( 21 ) with a degree of bonding stronger than the degree of bonding of the transverse strip ( 22 ), and then an anchoring strip ( 23 ) also with a degree of bonding stronger than the degree of bonding of the transverse strip ( 22 ).

5. The pack as claimed in claim 1 , wherein the closure tab ( 20 ) or an actuating tab thereof ( 24 ) is connected permanently to the inside of a lid front wall ( 31 ) of the outer pack ( 25 ).

6. The pack as claimed in claim 5 , wherein the closure tab ( 20 ) or the actuating tab thereof ( 24 ) is connected permanently to the inside of the lid front wall ( 31 ) of the outer pack ( 25 ) by means of a glue strip ( 32 ) and/or glue dots ( 41 ) on an outside of the actuating tab ( 24 ).
