Abstract
A waste paper receptacle/compactor employing a container section and a lid section. Suspended within the container section is an expandable liner with a cylinder supported inside of the liner at the top thereof. The cylinder serves as a staging area for placement of spent and crumpled paper towels. The cylinder works in conjunction with a piston which extends down from the lid section. The liner is biased to contract circumferentially. In such manner, when a used desires to discard spent and crumpled paper towels, that user opens the lid section and inserts the towel into the staging area and allows lid section to close thereon. The piston drives the paper towel down into the liner below the cylinder. The inwardly direction bias of the liner prevents the towels from opening or flowering in the container section. A loop is provided at the top of the liner providing a handle for extracting a full liner from the container section. Pulling on the loop to extract a full liner results in an automatic closure of the open end of the liner.
