A rigid pack of substantially parallelepiped appearance for tobacco products appears as a container (5) with an open top end (6), surmounted by a lid (7) hinged to the container ( 5) and rotatable between positions in which the top end (6) is open and closed. The pack (1) presents four lateral faces (17, 18, 19), and two end faces (12, 16) disposed mutually parallel and perpendicular to the lateral faces (17, 18, 19); at least one of the six faces (12, 16, 17, 18, 19) presents a raised portion (22) with an outwardly directed convex profile obtained by plastically deforming at least one panel (43, 44) of a blank ( 31) before the blank is folded around the tobacco products to fashion the pack (1).

What is claimed is: 1. A pack of rigid type for tobacco products, presenting lateral faces (17, 18, 19) and end faces (12, 16) and comprising a wrapper (4) composed of a container (5) with an open top end (6), and a lid (7) by which the open top end is closed, characterized in that at least one fac
What is claimed is: 1. A pack of rigid type for tobacco products, presenting lateral faces (17, 18, 19) and end faces (12, 16) and comprising a wrapper (4) composed of a container (5) with an open top end (6), and a lid (7) by which the open top end is closed, characterized in that at least one face ( 12, 16, 17, 18, 19) of the pack (1) presents at least one raised portion (22) with an outwardly directed convex profile, the raised portion (22) occupying an area of the respective face (12, 16, 17, 18, 19) coinciding both with the container (5) and with the lid (7). 2. A pack as in claim 1, wherein the raised portion (22 ) occupies a substantially central area of the respective face (12, 16, 17, 18, 19), excluding the parts adjacent to the edges of the selfsame face. 3. A pack as in claim 1, wherein the raised portion (22 ) occupies a substantially central area of the respective face (12, 16, 17, 18, 19) and extends at least in part to meet the edge of the selfsame face. 4. A pack as in claim 1, wherein the raised portion (22 ) is presented by the lateral faces (17, 18). 5. A pack as in claim 1, wherein the raised portion (22 ) is presented by each one of the faces (12, 16, 17, 18, 19). 6. A pack as in claim 1, wherein the raised portion (22 ) presents a substantially flat central portion (56). 7. A pack as in claim 1, wherein the raised portion (22 ) presents a surrounding fillet (57) by way of which the central portion (56) is joined to the corresponding face (12, 16, 17, 18, 19) of the pack (1). 8. A pack as in claim 7, wherein the fillet (57) comprises rectilinear segments interconnected by curved segments. 9. A pack as in claim 8, wherein the fillet (57) comprises rectilinear segments connected one to the next by sharp corners. 10. A pack as in claim 1, wherein the wrapper (4) presents bevelled longitudinal corner edges (26). 11. A pack as in claim 1, wherein the wrapper (4) presents rounded longitudinal corner edges (25). 12. A pack as in claim 1, wherein the wrapper (4) presents a band (27) of curved section extending along each of the longitudinal corner edges and disposed with the concave face directed inwards, by which a relative central part (28) of one lateral face (17, 18, 19) is joined to an adjacent lateral face (17, 18, 19) along a sharp corner edge (29). 13. A pack as in claim 1, presenting a substantially parallelepiped appearance with a lid (7) hinged to the container (5) and rotatable thus between positions in which the top end ( 6) is open and closed, wherein the wrapper (4) presents four longitudinal corner edges (58) defining four lateral faces ( 17, 18, 19) disposed in mutually parallel pairs, and two end faces (12, 16) disposed mutually parallel and perpendicular to the lateral faces (17, 18, 19). 14. A pack as in claim 13, comprising a frame (21) fixed to the container (5), projecting in part from the open top end (6) so as to interact with and stabilize the lid (7) when occupying the closed position, and presenting at least one raised portion with a convex profile projecting outward from the pack (1). 15. A pack as in claim 14, wherein the raised portion of the frame (21) is positioned in full frontal contact with an inside surface of a raised portion (22) presented by a lateral face ( 17, 19) of the pack (1). 16. A pack as in claim 1, wherein the tobacco products consist in a plurality of packets of cigarettes (2), and the pack (1) is a carton (3). 17. A pack as in claim 1, wherein the tobacco products consist in a group of cigarettes, and the pack (1) is a cigarette packet (2). 18. A method of manufacturing packs of rigid type as in claim 1 obtainable departing from a flat diecut blank (31) presenting a plurality of longitudinal crease lines (35) and a plurality of transverse crease lines (36 . . .41) combining with the longitudinal crease lines (35) to define a plurality of panels ( 43, 44) coinciding singly or in overlapping association with the faces (12, 16, 17, 18, 19) of the pack (1), characterized in that it comprises the steps of advancing the blanks (31) along a predetermined conveying line ( 30) through a forming station (32), and deforming at least one of the panels (43, 44) plastically at the forming station (32) in such a way as to generate a raised portion (22). 19. A method as in claim 18, wherein the step of advancing the blanks (31) through the forming station (32) is a continuous operation. 20. A method as in claim 18, wherein the step of advancing the blanks (31) through the forming station (32) includes a pause at the selfsame station (32). 21. A method as in claim 19, wherein the plastic deformation step is implemented through the agency of a pair of rollers (45) operating in concert, contrarotating about axes (46) transverse to the conveying line (30) and located on opposite sides of the selfsame line (30), including at least a first roller (45) of which the cylindrical surface (47) presents at least one projection (48) functioning as a die such as will produce the raised portion (22). 22. A method as in claim 21, wherein the second roller ( 45) of the pair is embodied in resilient material. 23. A method as in claim 21, wherein the second roller ( 45) of the pair presents a cylindrical surface (47) affording at least one recess (49) functioning as a bottom die matched to the die of the first roller. 24. A method as in claim 20, wherein the plastic deformation step is implemented through the agency of a pair of tools (50) consisting in a punch (51) and a counter (52) operating in concert, invested with reciprocating motion relative to the conveying line (30) and located on opposite sides of the selfsame line ( 30), including at least a first tool (50) furnished with a projection (54) functioning as a die such as will produce the raised portion (22). 25. A method as in claim 22, wherein the second tool ( 52) of the pair (50) is embodied in resilient material. 26. A method as in claim 24, wherein the second tool ( 52) of the pair (50) presents a surface offered to the opposite tool (51) furnished with at least one recess (55) functioning as a bottom die matched to the die of the first tool. 27. A method as in claim 19, wherein the conveying line ( 30) carrying the blanks (31) and the forming station (32 ) are an integral part of a machine (34) by which the packs ( 1) are manufactured.
