A cosmetic case comprises a lid (10) and a base comprising a tray (12) and a base outer (shell 15). The lid (10) is connected to the base by a hinge. The hinge comprises a torsion biasing assembly (1) having relatively rotatable parts (2, 3) which interfit to retain a torsion element (4), so that relative rotation of the parts changes the strain in the torsion element. The tray (12) is connected to the lid (10) by the hinge and the base outer shell (15) is fitted to the cosmetic case by being attached to the tray (12). The base outer shell (15) preferably comprises a stop to prevent the lid or base from dis-engaging from the torsion biasing assembly. |
