Abstract

An animal-resistant system for a profiled plastic container has a lid hinged to the container and a latch mechanism having a plurality of radially extending latching pins supported by the lid. A rotary handle actuates the latching pins radially to engage pin receiving holes at the top edge of the container. The cam actuates the latching pins radially outward against biasing to engage the top edge and when the handle is rotated, the cam releases the latching pins to be biased inwardly to release the lid for opening to an open position. Collection equipment can engage lifting bars and remotely actuate the latch mechanism through a release linkage to the cam. An internal safety release can be incorporated into the cam to disable the cam and permit the latching pins to bias to the unlatched position.

Description

FIELD OF THE INVENTION

[0001] The invention relates to animal resistant trash containers or bins and lids and latching mechanisms for such bins which are operable by humans but resistant to operation by non-human animals. More particularly, a plastic lid is fit with a pin-latch arrangement for coupling with the periphery of the top of a plastic bin. BACKGROUND OF THE INVENTION

[0002] Many containers or bins are now available for the receipt of consumer waste and trash. Of particular concern is food waste which can unfavorably attract pests and potentially dangerous animals such as bears. Typically metal bins are used which combine rugged structures with openings and rigid lids fit with, or otherwise having, concealed latches.

[0003] To date, plastic bins have been avoided due to the ease with which a bear can crush the main receiving structure of the bin and, as a result, dislodge or otherwise bypass the lid entirely.

[0004] Further, while providing animal resistant access, automate...
