ABSTRACT:
A hinge (16) pivotally connects a lid (14) to a body (12) of a container (10) for releasably holding the cover (14) at both open and closed positions. The hinge (16) has a pair of hinge leaves (22, 22A) and a boss (48) extending from one leaf (22) forms an outer cam surface having a pair of relatively flat cam portions (50, 52) on opposed sides of a high point (54) of the cam. The other leaf (22A) has a lip (42A) extending therefrom with the inner surface of the lip (42A) riding along the outer surface of the cam formed by the one leaf (22) to define a cam follower which forms a latch member. A high portion (54) of the cam by contacting the lip (42A) restrains movement of the cover (14) at both the open and closed positions thereof until an opening force of a predetermined magnitude is exerted against the cover (14) for moving the lip ( 42A) over the high portion (54) of the cam. The hinge (16) may be formed of identical hinge leaves (22, 22A) thereby to simplify the manufacture and assembly of the hinge (16).
