Patent attributes
A rigid hinged-lid packet for tobacco products appears as container (3) with an open end (4), and a lid (5) hinged to the container (3) so as to rotate between positions in which the open end (4) is open and closed, also a stiffening frame (15) projecting from the open end (4) and presenting two side pieces (19) destined to enter into contact with the insides of two respective flank faces (13) of the lid (5) when the packet is closed. To retain the lid (5) more firmly in the closed position, the inside of each flank face (13) is fashioned with a freely projecting tongue (52) bent inwards in such a manner that when the lid (5) is returned to the closed position, the tongue (52) will locate in an opening (55) afforded by a slit (54) formed in the corresponding side piece (19) of the frame (15).
