The box (1) has a main body (8) comprising two adjacent profiled and joined longitudinal walls (2, 2') along adjacent edges. Profiles (4, 4') partially form the longitudinal walls, which are connected with each other by a bar that is made of a flexible material e.g. film. The bar forms a hinge (5), and is compounded with the profiles in a single-piece. The profiles form a composite profile (6) together with the hinge. The profiles comprise a hollow structure with an inner wall (7) and outer wall (7'). The hinge forms continuation of the profiles or inner wall and outer wall of the profiles. |
