ABSTRACT:
A spring latch, hinge and boss assembly for closure members generally on containers such as compacts for powder and other cosmetics includes, spaced hinge elements on one peripheral side of the closure or cover member and base member to permit pivotal movement of the closure or cover member from open to closed position and vice versa relative to the base member and a boss member disposed between the hinge elements so that a force must be exerted on the closure member during closing movement. The materials of the boss member are harder than the material for the closure member and the base member. The boss member is constructed with a designed resistance to closing and to opening of the closure member relative to the base member. Alternatively and selectively and even though made of a harder material the boss can be designed so that in assembled position it can be rigid and non-yielding or can flex depending on the materials selected for the closure member, base member and boss and the shape of the boss member. The closing and opening movement of the closure member produces and audible clicking sound under coaction with the boss member.
