Waste container with displaceable panel closure

A container having walls and an open end defined by edge portions of said walls comprising:

• a moveable rear wall having a peripheral frame mounted on said container adjacent to said edge portions so as to sealably engage and disengage said edge portions;
• and
• an adjustable door stop assembly including a first stop blade fixedly positioned on said peripheral frame and a second stop blade removably fastened to said first stop blade wherein;
• (i) when said moveable rear wall is arranged in a first sealed engagement with said edge portions, said second stop blade engages said edge portions;
• and
• (ii) when said second stop blade is unfastened and removed from said first stop blade and then said moveable rear wall is arranged in a second sealed engagement with said edge portions, said first stop blade engages said edge portions.

A pressure release assembly for use on a container comprising:

• a vent panel sized so as to be mounted within a wall of said container so as to allow for air flow communication with an interior volume;
• a cover plate arranged in spaced relation to said vent panel so as to define an enclosed void space therebetween;
• and
• a flapper assembly including a flapper-plate pivotally mounted on said wall of said container so as to define an entrance into said void space wherein when a differential in air pressure exists between said interior volume and the ambient environment outside of the container, said flapper-plate pivots between a closed and substantially sealed first position and an open second position.

A container including a plurality of sidewalls, a bottom wall, and a top wall wherein at least one of said walls is movable, and wherein all of said walls are arranged so as to enclose and define a volume, further including a pressure release assembly comprising:

• a vent panel positioned within one of said sidewalls so as to allow for air flow communication with said volume;
• a cover plate positioned on said one of said sidewalls in spaced relation to said vent panel so as to define an enclosed void space therebetween;
• and
• a flapper assembly including a flapper-plate pivotally mounted on said one of said sidewalls, between said cover plate and said one of said sidewalls so as to define an entrance into said void space wherein when a differential in air pressure exists between said volume and the ambient environment outside of the container, said flapper-plate pivots between a closed and substantially sealed first position and an open second position.
