摘要： Described is a packet for tobacco products, having a longitudinal axis (A) of main extension and four side walls (2, 3, 4, 5), which define a front wall (2), a rear wall (3) and a pair of sides (4, 5), a bottom wall (6) and a top wall (7); each side wall (4, 5) is joined to the front wall (2) and to the rear wall (3) by respective connecting edges (8, 9, 10, 11); along each of the above-mentioned connecting edges (8, 9, 10, 11) there is at least one corner wall (17) which has a transversal dimension variable along a direction parallel to the longitudinal axis (A) and is defined by respective side edges (18) which extend diverging from at least one first shared vertex (19), provided along the edge (8, 9, 10, 11) of the packet (1), and converging at least on a second shared vertex (20), also provided along the same edge (8, 9, 10, 11); the side edges (18) define for each side wall (2, 3, 4, 5), at least limited to the above-mentioned portion touched by the side edges (18) of the corner walls (17) and between these side edges (18), a deformation which extends towards the outside of the edge of the packet (1) in such a way as to keep substantially constant the perimeter extension of each transversal section of the packet (1) executed transversely to the longitudinal axis (A).
