The vacuum storage container of claim 21 wherein said pump is attached to said receptacle along with a power supply and a switch interposed between said power supply and said pump, wherein an openable lid is coupled to said receptacle, said openable lid adapted to close said receptacle to substantially enclose said interior space, wherein a lever is pivotably attached to said receptacle, said lever adapted to be pivotable between an open position where said lid can be opened and a closed position where said lid is held closed, said lever adapted to actuate said switch when said lever is pivoted to said closed position.
23. The vacuum storage container of claim 22 wherein said lid is hingedly attached to said receptacle; and
wherein a gasket is interposed between a perimeter of said lid and a rim of said receptacle, said gasket adapted to be compressed somewhat and substantially preclude air migration therethrough.
24. The vacuum storage container of claim 23 wherein said lever includes a clamp pivotably attached to said lever, said clamp having a knob at an end thereof most distant from said lever, said knob adapted to engage a portion of said lid spaced from where said lid is pivotably attached to said receptacle with said knob adapted to apply a closing force upon said lid when said lever is pivoted toward said closed position.
25. The vacuum storage container of claim 22 wherein said power supply includes at least one battery, and wherein said pump is coupled to a control system including a pressure sensor adapted to sense pressure within said substantially enclosed interior space, said control system adapted to deactivate said pump when a desirably low pressure is sensed within said interior space.
26. The vacuum storage container of claim 21 wherein said valve of said bleed port includes a flexible structure with a surface overlying said entry of said bleed port; and
wherein said entry of said bleed port is surrounded by a seal, said seal adapted to be compressed when said flexible structure of said valve abuts said seal.
