ABSTRACT:
A lid made of a syntheticresin and swingable like a cover for a book to open or close the opening of a container. A leg or legs of desired length extending rearwardly from the rear end of a lid plate renders the lid plate capable of maintaining a desired open position, and moving automatically into its open and closed positions. Such capabilities of the lid plate depend on the force created by a flat surface carrying a hinge base to urge the free end of the leg upwardly, the elasticity of a hinge and the hinge base, and the distance defined between the hinge and the free end of the leg which has been moved. The lid is particularly suitable for a compact for a cosmetic, or the like.
