Trash container lid system

Abstract

A trash container lid system for placement on top of large industrial trash bins of the type utilized in hotels, apartment houses, etc., in which a lid section counterweighted in the rear portion thereof is slidably and rotatably coupled to a trash bin via a roller in the mid portion of the lid section in a track on the top of the side edges of the trash bin and a roller in the rearward bottom portion of the lid section trapped in an arcuate downwardly extending track so that by sliding the lid to the rear the back track automatically raises the front of the lid section for the deposit of trash therein and upon inverting the trash bin, the lid section automatically falls completely open.
