  • Patent number: 4696412
    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.
