Abstract
Abstract A waste container has top opening closed by a lid member. A pair of arms is pivotally mounted on opposed ends of the container. The lid member is pivoted relative to its rear edge to the upper ends of the arms. The arms are of a length and so mounted to the container ends that the lid can be moved between a closed position and an open position with the front edge of the lid sliding along the upper edges of the container ends. A pair of springs connected between each arm and the container assists pivotal movement of the arms relative to the container during sliding movement of the lid across the container opening. When the container is inverted for emptying, the lid pivots relative to the arms to facilitate discharge of waste from the container.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
288 words
A waste container having a pair of arms extending upwardly from pivotal connections on opposed container end walls, each pivotal connection comprising a frusto-conical mounting member fixed to the respective end wall and a pivot stud extending from the frustum surface of the mounting member to receive the respective arm so that it is spaced from the container end wall, hinge means pivotally connecting upper ends of the arms to a rear edge of a curved lid which closes at least two thirds of the area forming the container opening as defined by the upper curved edges of the end walls and upper edges of front and rear walls, a rear closure panel closing the remaining rear portion of the container opening, the length of the arms and location of the mounting members therefore being so arranged that the rear edge of the lid is raised relative to a front edge of the rear closure panel to permit the lid to be pivoted rearwardly about the pivot studs, guide means on the front, outer edges of the lid which engage and slide along the curved upper edges of the end walls during opening and closing movement of the lid, stop means on the container end walls to limit relative pivotal movement of the arms, and biasing means on each end of the container, each said biasing means comprising a pair of compression springs disposed end to end in a housing pivoted at one end to a respective end wall, an operating rod extending through an opening in the other end of the housing and pivotally connected to a respective arm, and abutment means connected to the operating rod and disposed between the adjacent ends of the compression springs.
