A rigid suitcase includes first and second shells defining a first storage volume, the outer surface of the first shell including a recess, and an auxiliary container defining a second storage volume, physically separate from the first storage volume, and adapted to be moved between an inserted state in which the auxiliary container is at last partially housed in the recess and a removed state, in which the auxiliary container is completely extracted from the recess. The rigid suitcase further includes guide members operable to guide the auxiliary container as it moves from the inserted state to the removed state and vice versa, and removable attachment members operable between the first shell and the auxiliary container and adapted to be actuated between an attached state, in which the auxiliary container cannot be removed from the recess and a released condition in which the auxiliary container can be removed.

1. A rigid suitcase comprising: a first shell and a second shell which are hinged to each other and have outer surfaces and inner surfaces respectively, wherein said inner surfaces face each other to define a first storage volume, the outer surface of said first shell comprising a recess projecting into said first storage volume and delimited by a bottom wall and side walls of the outer surface of the first shell;an auxiliary container defining a second storage volume that is physically separate from said first storage volume, said auxiliary container being adapted to be moved between an inserted state, in which the auxiliary container is at least partially housed in said recess and a removed state, in which the auxiliary container is completely extracted from said recess;guide members operable between said recess and said auxiliary container and designed to guide said auxiliary container as the auxiliary container moves from the inserted state to the removed state and from the removed state to the inserted state;removable attachment members operable between said first shell and said auxiliary container and adapted to be actuated between an attached state, in which the auxiliary container cannot be removed from said guide members and a released condition in which the auxiliary container may be removed from said guide members;wherein said bottom wall of the outer surface of said first shell in which said recess is formed is concave with a concavity facing toward the exterior of the first storage volume, so that a central portion of the bottom wall is farther from a rear wall of the auxiliary container than peripheral portions of the bottom wall, orwherein the rear wall of said auxiliary container facing said recess is concave with a concavity facing toward the exterior of the second storage volume, so that a central portion of the rear wall is farther from the bottom wall than peripheral portions of the rear wall. 2. The rigid suitcase as claimed in claim 1, wherein said side walls of the outer surface extend from said bottom wall; said auxiliary container comprising at least one portion made of a rigid material which, in its inserted state, faces the bottom wall and extends between the side walls of the recess. 3. The rigid suitcase as claimed in claim 2, wherein said guide members comprise substantially rectilinear projections integral with at least one side wall of the recess or with the auxiliary container, and slidably engage grooves integral with the auxiliary container or integral with at least one side wall of the recess. 4. The rigid suitcase as claimed in claim 3, wherein each projection is parallel to its respective groove and is inclined to an ideal line perpendicular to a base side wall of the recess by 1° to 10°. 5. The rigid suitcase as claimed in claim 3, wherein said projections comprise at least one wing integral with said first shell and said grooves comprise at least one channel formed in said auxiliary container; said wing engaging said channel in said inserted state of the auxiliary container. 6. The rigid suitcase as claimed in claim 3, wherein said projections or said grooves are integral with or formed in said rigid portion of said auxiliary container. 7. The rigid suitcase as claimed in claim 6, wherein said removable attachment members comprise an anchor element having respective slots for receiving and holding a portion of the sliding clip of the zipper of the two shells and a portion of the sliding clip of the zipper of the auxiliary container; said anchor element being placed on the outer surface of the first shell. 8. The suitcase as claimed in claim 7, wherein said anchor element has a pushbutton for simultaneous release of the sliding clips from the slots. 9. The rigid suitcase as claimed in claim 2, wherein said bottom wall has a rounded ogival shape, where the apex of the ogive is located substantially at the center of the bottom wall and is connected to the peripheral edges of the bottom wall by continuously tapering curved surfaces. 10. The rigid suitcase as claimed in claim 9, wherein the camber of said concavity ranges from 2 mm to 8 mm. 11. The suitcase as claimed in claim 1, wherein said outer surface of said first shell in which said recess is formed comprises a stiffening rib. 12. The suitcase as claimed in claim 11, wherein said rib comprises a groove formed directly on said bottom wall of the recess; said groove comprising a bottom wall which is offset from and parallel to the bottom wall of the recess. 13. The rigid suitcase as claimed in claim 1, wherein said first and second shells are adapted to be attached to each other by means of a zipper having at least one sliding clip for closing and opening the zipper and providing access to said first storage volume; said auxiliary container comprising at least one zipper having at least one closing and opening sliding clip to provide access to said second storage volume. 14. The rigid suitcase as claimed in claim 1, wherein said first storage compartment has at least three times the capacity of the second storage volume. 15. A rigid suitcase comprising: a first shell and a second shell which are hinged to each other and have outer surfaces and inner surfaces respectively, wherein said inner surfaces face each other to define a first storage volume, the outer surface of said first shell comprising a recess projecting into said first storage volume;an auxiliary container defining a second storage volume that is physically separate from said first storage volume, said auxiliary container being adapted to be moved between an inserted state, in which the auxiliary container is at least partially housed in said recess and a removed state, in which the auxiliary container is completely extracted from said recess;guide members operable between said recess and said auxiliary container and designed to guide said auxiliary container as it moves from the inserted state to the removed state and from the removed state to the inserted state;said guide members comprising substantially rectilinear projections which are joined to at least one side wall of the recess or to the auxiliary container and that slidably engage grooves joined to the auxiliary container or to at least one side wall of the recess;wherein said projections are not parallel, and said projections converge to an ideal point external to a perimeter defined by the suitcase. 16. The rigid suitcase as claimed in claim 15, wherein a distance between the projections as measured at a portion of the recess opposite to a base side wall is greater than the distance between the projections as measured near the base side wall of the recess.
