Abstract
A vacuum-release waste receptacle designed to prevent vacuum adherence of a plastic liner disposed within the present receptacle upon removal of the liner. The present invention provides a waste receptacle including a plurality of air baffles formed on the inner sidewalls of the receptacle and projecting inwardly into the interior space of the receptacle and to its bottom wall. The air baffles are fabricated to a predetermined dimension, which is calculated to provide an indentation of sufficient depth in the filled plastic liner to create air conduits between the plastic liner, the air baffles, and the inner surface of the receptacle. The air conduits permit the ingress of atmospheric air into the receptacle providing for vacuum-release of the plastic liner upon its removal. Various alternative embodiments of the present waste receptacle are disclosed featuring different configurations of the air baffles.
