ABSTRACT:
A blow-molded plastic container base and cover portions formed of double wall construction are hinged together for movement between open and closed positions with respect to one another. A latch assembly is provided for positively locking the cover portion in a closed disposition. The latch assembly includes an elongated bolt means slidably mounted within a trough-shaped groove in the front of the cover portion. The cover and base further include formed portions which matingly engage with one another upon closing of the cover and which include aligned locking apertures. Upon closing of the cover portion, the bolt means may be slid axially into the aforesaid apertures to positively lock the cover and base together. The bolt means further includes a detent means extending radially outward and which may be rotated into a cut-out portion in the trough-shaped groove when the bolt is engaged within the locking apertures. The detent means thereby serves to axially lock the bolt into a fixed position when the cover is locked to the base portion of the container.
