Abstract
Abstract A wastebasket includes a container and a lid which is mounted on the container. The container is formed with an opening providing access to the container's interior. The lid is pivotable about a pivot axis to cover and at least partially uncover the container opening. The pivot axis divides the lid into a forward portion and a rearward portion which are respectively disposed on opposite forward and rearward sides of a vertical plane encompassing the pivot axis when the lid is in a position covering the container opening. The forward portion of the lid has a greater cross-sectional area than the rearward portion, and the rearward portion has a greater weight than the forward portion. The lid is pivotable between a first position, where the lid substantially covers the container opening, and a second position, where the forward portion of the lid is disposed inwardly of the container and uncovers at least a portion of the container opening.
