Definitions

• the present invention relates to a rigid container for tobacco articles .
• the present invention is particularly advantageous for use in the manufacture of packets of cigarettes, and more specifically to rigid, hinged-lid packets, to which reference is made in the following description purely by way of example.
• Conventional rigid hinged-lid packets are normally in the form of a rectangular-section parallelepiped, and comprise two, respectively top and bottom, end walls,- and a lateral surface bounded by the end walls and defined by two, respectively front and rear, major lateral walls, and by two minor lateral walls .
• Each minor lateral wall is connected to both the major lateral walls at two sharp square longitudinal edges, and each end wall is connected to the lateral walls at four sharp square transverse edges .
• Rigid packets of the above type have several drawbacks by being unanato ical in shape, and by causing rapid wear of any clothing fabrics with which they come into contact .
• a rigid, substantially parallelepiped-shaped container for tobacco articles comprising two end walls, and a lateral surface bounded by the end walls and defined by two, respectively front and rear, major lateral walls, and by two minor lateral walls; at least one lateral wall having an outwardly convex profile, and being connected to the adjacent lateral walls along respective longitudinal edges; the- container being characterized in that said longitudinal edges are rounded edges .
• a rigid, substantially parallelepiped-shaped container for tobacco articles comprising two end walls, and a lateral surface bounded by the end walls and defined by two, respectively front and rear, major lateral walls, and by two minor lateral walls,- at least one lateral wall having an outwardly convex profile, and being connected to the end walls along respective transverse edges,- the container being characterized in that said transverse edges are rounded edges .
• a rigid, substantially parallelepiped-shaped container for tobacco articles comprising two end walls, and a lateral surface bounded by the end walls and defined by two, respectively front and rear, major lateral walls, and by two minor lateral walls; at least one end wall having an outwardly convex profile, and being connected to the corresponding lateral walls along respective transverse edges; the container being characterized in that said transverse edges are rounded edges .

• Number 1 in Figures 1 to 14 indicates as a whole different packets of cigarettes defining respective embodiments of the rigid container for tobacco articles according to the present invention.
• Each packet 1 contains an orderly group of cigarettes wrapped in a sheet of foil wrapping material (not shown for the sake of simplicity) .
• Each packet 1 comprises a cup-shaped bottom container 2 having an open top end 3; and a cup-shaped top lid 4 hinged to container 2 along a hinge 5 to rotate, with respect to container 2, between an open and a closed position respectively opening and closing end 3.
• lid 4 imparts to packet 1 a substantially rectangular parallelepiped shape defined by a lateral surface 6, and by two facing, respectively top and bottom, end walls 7 and 8, which are flat, identical and parallel and bound lateral surface 6.
• Lateral surface 6 comprises two parallel, facing, flat minor lateral walls 9; and two flat, facing major lateral walls 10 and 11 crosswise to minor lateral walls 9. More specifically, one major lateral wall 10 defines a front wall of packet 1, and the other major lateral wall 11 defines a rear wall of packet 1.
• Packet 1 also comprises a collar 12, which is folded into a U and glued inside cup-shaped container 2 so as to project partly outwards of end 3 and engage a corresponding inner surface of lid 4 when lid 4 is- in said closed position.
• transverse edges 13 are defined between minor lateral walls 9 and major lateral walls 10, 11; and eight transverse edges 14, perpendicular to longitudinal edges 13, are defined between end walls 7, 8 and lateral walls 9, 10, 11. More specifically, the eight transverse edges 14 are divided into four minor transverse edges 14, i.e. bounding minor lateral walls 9, and four major transverse edges 14, i.e. bounding major lateral walls 10, 11.
• each major lateral wall 10, 11 has an outwardly convex profile, is connected to each minor lateral wall 9 along a respective longitudinal edge 13, and forms, with each minor lateral wall 9, a respective substantially obtuse dihedral angle. More specifically, each longitudinal edge 13 is a rounded edge for seamlessly connecting the corresponding major lateral wall 10, 11 to the corresponding minor lateral wall 9 with no sharp edges.
• Each major lateral wall 10, 11 comprises a flat central portion 15 ,- and two precreased lateral bands 16 , each curving with its concavity facing inwards to connect central portion 15 to the corresponding minor lateral wall 9, and to form with minor lateral wall 9 a respective substantially obtuse dihedral angle.
• Each lateral band 16 is precreased by a number of longitudinal crease lines 17 imparting to lateral band 16 a relatively wide curve, i.e. with a relatively large curve radius Rl.
• Each rounded longitudinal edge 13 is defined by a number of longitudinal crease lines 18 imparting to rounded longitudinal edge 13 a relatively tight curve, i.e. with a relatively small curve radius R2.
• the ratio between curve radius Rl and curve radius R2 is therefore greater than l.
• both lateral bands 16 and rounded longitudinal edges 13 may vary in curvature, i.e. may have varying respective curve radii Rl and R2.
• curve radius Rl of the lateral bands is at any rate over 4 mm.
• the curve radius Rl of lateral bands 16 varies and tends to decrease slightly towards longitudinal edges 13, while radius R2 is substantially constant.
• radius Rl ranges between 25 mm and 50 mm, and radius R2 between 1 mm and 3 mm, with a radius Rl to R2 ratio of no less than 8.
• Longitudinal crease lines 17 of lateral bands 16 are spaced relatively far apart to impart relatively large curve radius Rl to lateral bands 16, while longitudinal crease lines 18 of rounded longitudinal edges 13 are relatively close together to impart relatively small curve radius R2 to rounded longitudinal edges 13.
• Each end wall 7, 8 is substantially rectangular, and has rounded corners with curve radii Rl and R2 to adapt to the outwardly convex profile of major lateral walls 10, 11.
• collar 12 is connected to an inner surface of front wall 10 and to an inner surface of each minor lateral wall 9, which it matches in shape, including the rounding of longitudinal edges 13 adjacent to front wall 10.
• packet 1 in Figures 1 to 7 is formed from a corresponding flat, substantially elongated rectangular blank 19, the parts of which are indicated, where possible, using the same reference numbers, with superscripts, as for the corresponding parts of packet 1.
• Each blank 19 (which has a central longitudinal axis 20) comprises longitudinal crease lines 18; and a number of transverse crease lines 21 defining, between longitudinal crease lines 18, a panel 10' forming a top portion of front wall 10 (and in particular the portion forming part of lid 4), a panel 7' forming top end wall 7, a panel 11' forming rear wall 11, a panel 8' forming bottom end wall 8, and a panel 10" forming a bottom portion of front wall 10 (and in particular the portion forming part of container 2) .
• Each panel 10', 10", 11' has two lateral wings 9' and 9" located on opposite sides of relative panel 10', 10", 11' and separated from relative panel 10', 10", 11' by longitudinal crease lines 18.
• Panel 10 ' has a reinforcing flap 22; and each wing 9', 9" of panel 11' has substantially rectangular longitudinal appendixes 23 located at opposite ends of wing 9', 9" and aligned longitudinally with each other.
• each packet 1 When forming each packet 1, the two lateral wings 9' and the two lateral wings 9" are superimposed and glued together to define respective minor lateral walls 9 of packet 1,- and each longitudinal appendix 23 is folded squarely with respect to relative lateral wing 9 ' or 9" , and is superimposed on and glued to an inner surface of a relative panel 7 ' or 8 ' to define an inner portion of a relative end wall 7 or 8 of packet 1 respectively.
• transverse crease lines 21 are weaker than longitudinal crease lines 17 and 18 (also referred to as secondary crease lines) on account of transverse crease lines 21 defining sharp transverse edges 14, whereas longitudinal crease lines 17 and 18 serve to curve lateral bands 16 and rounded longitudinal edges 13 respectively with no sharp edges .
• packet 1 of cigarettes as described above produces little wear of clothing fabrics coming into contact with packet 1, and at the same time is highly anatomically shaped for easy handling.
• the highly anatomical shape is made possible by curve radii Rl and R2, and more specifically by curve radius Rl being larger than curve radius R2.
