ABSTRACT:
In hinge-lid packs comprising a pack part (12) and a lid (13) hinged to a pack rear panel (15) it is difficult to ensure a precise closed position of the lid (13). This is particularly the case in hinge-lid packs with rounded longitudinal edges (10, 11). To create an additional closing force, outwardly directed deformations, particularly convexities (38), are formed in the free portion of collar side panels (28, 29) of a collar (26). These convexities abut the inner sides of the lid side panels (17) with an increased friction and thus create an increased closing force. The deformation of the collar side panels (28, 29) is a result of longitudinal collar edges (30, 31) diverging towards the free edge. As a result, there is a strain of material which effects the deformation of the collar side panels (28, 29). A further or alternative closing aid is provided in the form of an upright or inclined cut (39) arranged in the region of the collar side panels (28, 29). As a result of the convexity (38), this cut (39) forms a projecting retaining edge which also abuts the inner side of the pack side panels (28, 29) and creates an increased closing force. Moreover, the pack or the blank has a special design, such that rounded contours at the ends of the blanks fit into one another and can be severed from a piece of material without any waste.
