Abstract

A cigarette pack, having an inner pack for pack contents, in particular for a group of cigarettes, and having an outer pack, preferably in the form of a hinge/lid pack, wherein the inner pack which preferably directly encases the pack contents has lateral walls made of cardboard, which are formed by overlapping lateral tabs of a blank for the inner pack. The invention is characterized in that end corner tabs, which are arranged on both sides of a lid wall of the inner pack, have a respective substantially V-shaped design, and in that each of the end corner tabs is arranged between inner lateral tabs and outer lateral tabs of the lateral walls of the inner pack.

First claim

What is claimed is:

1. A method for producing cigarette packs ( 10 ) comprising:
stamping a blank ( 33 ) for an inner pack ( 12 ) made of thin cardboard into a pocket ( 61 ) of a folding turret ( 60 ) during partial folding of the blank ( 33 ), the inner pack ( 12 ) having a front wall ( 36 ), an end wall ( 37 ), a rear wall ( 39 ), a bottom wall ( 48 ), inner lateral tabs ( 51 ) extending from the rear wall ( 39 ), bottom corner tabs ( 54 ) extending from the inner lateral tabs ( 51 ), end corner tabs ( 55 ) extending from the end wall ( 37 ), and outer lateral tabs ( 52 , 53 ) extending from the front wall ( 36 );
folding the inner lateral tabs ( 51 ) in a region of lateral walls ( 50 ) of the inner pack ( 12 ) and the bottom corner tabs ( 54 ) of the inner pack ( 12 ), the lateral walls ( 50 ) being formed by overlapping of the inner and outer lateral tabs ( 51 , 52 , 53 );
introducing a group of cigarettes ( 11 ) into the partially folded blank ( 33 );
folding the front wall ( 36 ) of the inner pack ( 12 ) onto the group of cigarettes ( 11 );
folding the end corner tabs ( 55 ) of the inner pack ( 12 ), which are arranged on both sides of the end wall ( 37 ) of the inner pack ( 12 ) and are connected thereto, into the inner lateral tabs ( 51 ) of the lateral walls ( 50 );
folding the outer lateral tabs ( 52 , 53 ) onto the end corner tabs ( 55 ) and the inner lateral tabs ( 51 ); and
ejecting the partially finished inner pack ( 12 ) from the pocket ( 61 ) of the folding turret ( 60 ) in conjunction with the folding of the front wall ( 36 ) of the inner pack ( 12 ), wherein the end corner tabs ( 55 ) are folded by folding devices ( 68 ) arranged fixed in an ejection station of the folding turret ( 60 ) into the respective plane of the lateral wall ( 50 ) of the inner pack ( 12 ).

2. The method as claimed in claim 1 , further comprising providing the inner pack ( 12 ) with a closure label ( 42 ) in a region of a label folding station ( 81 ), wherein the inner pack ( 12 ) facing transversely to a transport direction along an upright conveyor section ( 75 ) and having an exposed end wall ( 37 ) is transported in the transport direction facing sideways along the upright conveyor section ( 75 ), and the closure label ( 42 ) is positioned initially against the exposed end wall ( 37 ) and is then folded by means of a folding device ( 82 ) in the region of the rear wall ( 39 ) and the front wall ( 36 ).

3. The method as claimed in claim 2 , wherein the inner pack ( 12 ) has an access opening ( 35 ) in the region of the end wall ( 37 ) and the adjoining front wall ( 36 ) of the inner pack ( 12 ), wherein the closure label ( 42 ) is positioned on the inner pack ( 12 ) in such a way that the access opening ( 35 ) is closed.

4. The method as claimed in claim 2 , wherein the closure label ( 42 ) is positioned on the inner pack ( 12 ) in the label folding station ( 81 ) by means of the folding device ( 82 ), whereas the inner pack ( 12 ) is conveyed continuously in the transport direction, wherein the folding device ( 82 ) is moved together with the pack ( 12 ) in the transport direction also is moved transversely to the transport direction, in order to fold the closure label ( 42 ) against the rear wall ( 39 ) and the front wall ( 36 ).

5. The method as claimed in claim 2 , further comprising feeding the inner pack ( 12 ) with the closure label ( 42 ) positioned thereon to an outer pack folding turret ( 84 ) for the production of the outer pack ( 13 ), wherein a blank ( 30 ) for the outer pack ( 13 ) is stamped into a pocket of the outer pack folding turret ( 84 ) and is partially folded, and wherein the inner pack ( 12 ) with the closure label ( 42 ) is introduced into the outer pack ( 13 ) as pack contents, and a front wall, lateral walls, and a lid of the outer pack ( 13 ) are then formed by folding the blank ( 30 ) for the outer pack ( 13 ).
