Rigid package for tobaco articles

A rigid package for tobacco articles (3);

• the package (1) comprising a first container (2) for housing the tobacco articles (3), and a second container (4) for housing the first container (2) in sliding manner, so as to enable the first container (2) to slide, with respect to the second container (4), between a closed position, in which the first container (2) is fully inserted inside the second container (4), and an open position, in which part of the first container (2) is extracted from the second container (4);
• each container (2;
• 4) being substantially parallelepiped-shaped, and comprising two, respectively bottom and top, end walls (5, 6;
• 13, 14), and a lateral surface (7;
• 15) bounded by the end walls (5, 6;
• 13, 14) and defined by substantially parallel, opposite major lateral walls (8;
• 16), and by at least one minor lateral wall (9;
• 17) separated from the major lateral walls (8;
• 16) by corresponding longitudinal edges (10;
• 18);
• the package (1) being characterized in that the major lateral walls (8, 16) of both the containers (2, 4) are curved walls having the same concavity and the same radius of curvature (R), which is constant along the whole extension of each major lateral wall (8;
• 16).
