Abstract
A hinge-lid pack for cigarettes or the like. It is a common problem in hinge-lid packs comprising a pack part (10) and a lid (11) articulated on a rear panel (13) of the pack part (10), to reliably lock the lid (11) in an accurate closed position. This problem particularly appears in hinge-lid packs with rounded or bevelled longitudinal edges (27, 28). To ensure the precise closed position of the lid (11), material thickenings are formed in the region of the inner side of a lid front panel (17). In closed position, these thickenings exert an increased closing pressure on upper portions of a collar (23), particularly of a collar front panel (24). This closing pressure loads the lid (11) in the closed position.
Claims4
A hinge-lid pack, with rounded or bevelled longitudinal edges (27, 28), comprising a pack part (10) and a lid (11) articulated on a rear panel (13) of the pack part (10), and including a collar (23) which is arranged in the pack part (10) and partially projects therefrom and which is surrounded, in a closed position, in the region of a collar front panel (24) and collar side panels (25, 26) by a lid front panel (17) and lid side panels (19, 20) characterized in that the lid front panel (17) is provided at its inner side with at least one material thickening which, in the closed position of the lid (11), abuts the collar front panel (24) and creates an increased closing pressure;
- wherein the thickening at the inner side of the lid front panel (17) is located at a distance from a free lid edge (30) of said lid front panel (17), directly adjacent to a lid top panel (21);
- wherein the thickening abuts the collar front panel (24) in the region of lateral legs or webs (33, 34) of the collar front panel (24);
- wherein the thickening is formed from an inner lid tab (35) at the inner side of the lid front panel (17), by means of a local two-ply design of the inner lid tab (35);
- and
- wherein folding tabs (36, 37) which are attached to the inner lid tab (35) are folded between the inner lid tab (35) and the lid front panel (17) in order to form the thickenings.
A hinge-lid pack, with rounded or bevelled longitudinal edges (27, 28), comprising a pack part (10) and a lid (11) articulated on a rear panel (13) of the pack part (10), and including a collar (23) which is arranged in the pack part (10) and partially projects therefrom and which is surrounded, in a closed position, in the region of a collar front panel (24) and collar side panels (25, 26) by a lid front panel (17) and lid side panels (19, 20), characterized in that the lid front panel (17) is provided at its inner side with at least one material thickening which, in the closed position of the lid (11), abuts the collar front panel (24) and creates an increased closing pressure;
- wherein the thickening at the inner side of the lid front panel (17) is located at a distance from a free lid edge (30) of said lid front panel (17), directly adjacent to a lid top panel (21);
- wherein the thickening abuts the collar front panel (24) in the region of lateral legs or webs (33, 34) of the collar front panel (24);
- wherein the thickening is formed from an inner lid tab (35) at the inner side of the lid front panel (17), by means of a local two-ply design of the inner lid tab (35);
- and
- wherein two thickenings are arranged at the inner side of the lid front panel (17) in lateral regions which are directed towards the lid top panel (21), such that, in the closed position of the lid (11), said thickenings abut upper or free end portions of the webs (33, 34) of the collar front panel (24).
