ABSTRACT:
A rigid pack for tobacco products comprises an outer wrapper (3) furnished with a container (4) presenting an open top (5), surmounted by a lid (6) hinged to the container (4) and rotatable between a position in which the open top (5) is exposed and a position, interacting with a frame (20) anchored to the open top (5), in which the open top is closed, the tobacco products being enveloped by an inner wrapper (19). The pack (1) presents four lateral faces (16, 17, 18) arranged in two parallel pairs, also a top end face (15) and a bottom end face (11) disposed transversely to the lateral faces (16, 17, 18), which define a front, a back and two flanks. At least one of the lateral faces (16, 17, 18) presents a deformation referable to at least one bend line (21), coinciding with a crease line (3) impressed previously on the blank from which the pack is fashioned, and obtained by subjecting the flank faces (18) to compression in such a way that the bend line (21) is forced into relief.
