Abstract: The container (1) comprises two half-shells (3a, 3b). On the edges of the half-shells (3a, 3b) at least one male coupling element (15b) and at least two female coupling elements (15a) are formed. The half-shells (3a, 3b) can be plugged together in an arbitrary manner to form containers (1) or other structures, in that male coupling elements (15b) are engaged in gaps (17) between two adjacent female coupling elements (15a).
