Abstract
A container (10) includes a base portion (11) having a cover (12) attached thereto by a hinge assembly (13). Plates (25, 26) extend outwardly from the base portion (11) and together with arms (27, 28) extending outwardly from the cover (12) carry a latch mechanism (34) to maintain the cover (12) in an open position. The latch mechanism (34) includes complementary lock barbs (35, 38) on a plate (26) and an arm (28), each lock barb (35, 38) having a camming surface (36, 39) and a lock surface (37, 40). As the cover (12) is rotated, the camming surface (39) of the lock barb (38) rides over the camming surface (36) of the lock barb (35) until the lock surfaces (37, 40) engage each other.
