Vacuum-release waste receptacle

A vacuum-release waste receptacle for use in combination with a trash bag, said receptacle comprising:

• a plurality of sidewalls, each with an upper edge and an interior surface, and a bottom wall attached to said plurality of sidewalls such that said bottom wall and said plurality of sidewalls define an interior space, wherein said upper edges define an opening in communication with said interior space;
• and
• an air baffle comprising a generally L-shaped structure formed on said interior surface of at least one of said sidewalls and projecting inwardly into said interior space to a predetermined dimension to form an air conduit between the trash bag and said at least one sidewall, when the liner is positioned in said interior space, that is in fluid communication with said upper opening to provide pressure equalization within said receptacle.

A vacuum-release waste receptacle for use in combination with a trash liner, said receptacle comprising:

• a plurality of sidewalls, each with an upper edge and an interior surface, and a bottom wall attached to said plurality of sidewalls such that said bottom wall and said plurality of sidewalls define an interior space, wherein said upper edges define an opening in communication with said interior space;
• and
• vacuum-releasing means for pressure equalization within said receptacle including an air baffle formed on said interior surface of at least one of said sidewalls and projecting inwardly to a predetermined dimension forming an air conduit between the liner and said interior surface in fluid communication with said upper opening for the ingress of atmospheric air.

A vacuum-release waste receptacle for use in combination with a trash can liner, said receptacle comprising:

• a generally cylindrical sidewall having an upper edge and an interior surface, and a bottom wall attached to said sidewall so that said bottom wall and said sidewall define an interior space, wherein said upper edge defines an opening in communication with said interior space;
• and
• an air baffle formed on said interior surface of said sidewall and projecting inwardly into said interior space so as to form an air conduit between the liner and said sidewall, when the liner is positioned in said interior space, that is in fluid communication with said opening.

A method of providing pressure equalization for vacuum-release of a plastic liner disposed within a waste receptacle having an interior surface and a plurality of air baffles provided on said interior surface, said method comprising the steps of:

• positioning said liner within said receptacle in contact with said air baffles;
• and
• filling said liner with waste materials such that said liner is drawn across said air baffles under tension producing air conduits adjacent said air baffles in fluid communication with the atmospheric air.
