ABSTRACT:
The drawings disclose a closure mechanism for an ashtray and the like, including a pivotal cover member and a "U" shaped leaf spring, the cover member having detent projections formed on a portion thereof for cooperation with the spring. The spring exerts a force on the detent projections to retain the cover member in its closed position. The detent projections force the spring outwardly while the cover member is pivoted through a predetermined angle until the detent projections are pivoted over-center, after which the spring retains the cover member in its open position.
