Flip-top packet, particularly for cigarettes
First Claim
1. A flip-top cigarette packet made of cardboard and having a front wall, rear wall and side walls, a hinged lid pivotably adjoining the top of the rear wall, and a collar which partly projects upwardly out of the packet in an upper region of the front wall and of the side walls and which is surrounded by the hinged lid in the closed position of the packet, said packet characterized:
- in that a front wall (29) of the collar (28) has a central vertical fold line (33);
in that two continuation fold lines (35,
36) in the packet front wall (13) respectively extend from the bottom end of the vertical fold line (33) at the top edge (34) of the front wall (13) to bottom corners (37,
38) of the front wall (13) of the packet (10);
in that supplementary fold lines (40,
41) in the collar front wall (29) adjoin the bottom end of the vertical fold line (33) and extend toward the bottom corners (37,
38) in alignment with the continuation fold lines (35,
36) of the packet front wall (13);
in that all of the fold lines (33;
35, 36;
40
41) are pre-shaped grooves on the inside of the packet front wall (13) and collar front wall (29); and
in that fold lines are formed only in said packet front wall (13) and said collar front wall (29), said packet rear wall (15) and said hinged lid being free of fold lines, whereby squeezing pressure applied to said side walls causes only said packet front wall (13) and said collar front wall (29) to be outwardly deformed to form an enlarged approximately V-shaped opening to facilitate removal of a cigarette from a full packet, and whereby the packet returns to an un-deformed state upon release of the squeezing pressure.

Abstract
For the easier removal of the contents, particularly of cigarettes (32), of a flip-top packet, fold lines are pre-shaped (central fold line 33, continuation fold lines 35, 36) in the region of a front wall (13) and of a collar front wall (29) in a manner such that by application of pressure via side walls (21) the front wall (13) with the collar front wall, when the flip-top packet is open, are brought into a position which is V-shaped in cross-section.
