A latch is usable for latching and automatically unlatching a lid operative to close a bin of a waste container. The latch includes a release weight that is moveable responsive to gravity from a first position to a second position to cause the latch to disengage from a release mechanism when the latch is rotated to one or more angular positions in a dump angular orientation. The latch and release mechanism are held in latched engagement when release slide bolts and latch slide bolts are engaged in extended positions. Movement of the release weight causes the latch slide bolts to move to retracted positions to enable disengagement of the release slide bolts and latch slide bolts. A release knob is operative responsive to manual movement in two different directions to enable the latch and release slide bolts to disengage.

A latch is usable to latch and automatically unlatch a lid of a waste container. The latch includes a release weight that moves responsive to gravity in a housing from a first position to a second position to cause the latch to disengage from a release receptacle when the latch and the waste container are oriented in a dump angle orientation. The latch includes a rotary damper in the housing that controls movement of the release weight in the housing such that an amount of time for the release weight to move responsive to gravity from the first position to the second position is slower than the amount of time the release weight would move responsive to gravity from the first position to the second position in the housing absent the effect of the rotary damper on the release weight.

A retention arrangement for releasably securing a closure against a fixed body is provided. The retention arrangement includes a housing defining a mouth configured to receive a striker and defining a longitudinal axis, and at least one retention element configured to selectively retain the striker within the mouth, and movable between an open position and a closed position. The retention element is resiliently biased towards the closed position. The retention element is configured to open upon displacement due to the striker along the longitudinal axis in a first direction, and to close upon complete insertion of the striker within the mouth. The retention element is configured for rotation about at least two non-parallel axes so as to direct the striker towards the mouth.

Disclosed is a novel lock that includes a lock housing, lock cavity, a spring, a load plate, one or more pins, a post receiver and a post. The spring engages the lock cavity and load plate, securing the pins in place within a pin recess of the post receiver. The lock housing includes housing extensions to engage a case to lock the case in a closed configuration. The post receiver includes a pin guide with angled surfaces defining a travel path for the pins. The travel path, upon receiving input (e.g., a magnetic force and/or rotation) causes the pins to move up and out in response to force applied when a head region of the post pushes the pins apart.
