The folding box according to claim 3, wherein said polygonal prism has a square cross-section, and said plurality of polygonal sectors are mutually identical prisms whose cross-section is a small equilateral rectangular triangle wherein the hypotenuse of each corresponds to a junction fold with a respective face of said single-piece foldable structure. 5. The folding box according to claim 4, wherein said plurality polygonal sectors are connected in pairs by a fold to form each time, in said stable, unfolded position of said single-piece foldable structure, a prism whose cross-section is a large equilateral rectangular triangle whose surface is double said small equilateral rectangular triangles, said two thus formed large triangles being contiguous with each other at two said edges in said stable, unfolded position. 6. Box according to claim 1, wherein said single-piece foldable structure extends, in said flat, folded position parallel to said base plane, in a direction parallel to said longitudinal direction with which said folding crease forms an angle of 45°. 7. The folding box according to claim 2, wherein said polygonal prism forms the framework of a rectangular parallelepiped whose base is formed by said base and whose cover is formed by a flap comprised in said at least one packaging band. 8. The folding box according to claim 1, wherein said at least one packaging band includes, at both ends thereof in said longitudinal direction, two closing flaps arranged to move into superposition on each other when said at least one packaging band is in said folded position surrounding said single-piece foldable structure in the stable, unfolded position of said single-piece foldable structure, said two closing flaps including mutually complementary locking means to ensure said at least one packaging band is held in position wound around said single-piece foldable structure. 9. The folding box according to claim 1, wherein said at least two bearing faces comprised in said single-piece foldable structure define together, in said stable, unfolded position of said single-piece foldable structure, a plane edge surface arranged to act as support for a flap comprised in said at least one packaging band. 10. The folding box according to claim 2, wherein said at least one cross support includes a stop surface arranged to cooperate with one end of a flexible arm fixed to one of said two opposite faces to that carrying said at least one cross support, so as to hold said flexible arm in a buttress position between said two opposite faces in said stable, unfolded position of said single-piece foldable structure, to prevent said two opposite faces moving closer to each other. 11. The folding box according to claim 1, wherein said two opposite faces comprised in said single-piece foldable structure each include, aligned when said single-piece foldable structure is in its stable, unfolded position thereof, at least one cut-out portion for housing a cross member, arranged for receiving said cross member for the reception of an object, said cross member having a length at least equal to an external space of said two opposite faces carrying said cross member housing at least one cut-out portion. 12.
