Abstract: A vented trash container with a manifold of air channels which is capable of distributing air throughout the entire container. The vented trash container is capable of eliminating vacuum between walls of the container and a liner. The manifold in the container comprises a plurality of air channels and an air distributing means. The manifold forms a network of the air channels so as to provide air distribution throughout the entire container and enhance reliability of the air distribution. The vented trash container with the manifold can be cast form a single piece of a material to form an integrated seamless unit and easily manufactured by a single injection molding process.

Abstract: A vacuum release device for assisting removal of plastic bags from containers is disclosed. The device is a channel made from non-porous materials. The channel has multiple segments and is capable of being attached to both the sidewall and the bottom wall of a container. As the channel is attached to the walls of the container, an air conduit is formed to provide air conduction in the container. The attachment methods comprises mechanical, chemical, and adhesive. The channel has openings at the container's bottom wall and at the corner between the container's sidewall and bottom wall. The unique structure of the channel protects the openings from being blocked by a plastic liner.
