Abstract:
1. A method for eliminating air pockets and billowing when installing an empty flexible trash can liner in a trash receptacle and drawing the empty liner tight against the interior surfaces of the receptacle in a full open position, comprising the steps of: providing a trash receptacle having an outer base member with a bottom end adapted to be supported on a support surface and a peripheral side wall extending upwardly therefrom circumscribing a lower chamber and terminating in an open top end, an inner receptacle movably disposed in said outer base member having a bottom wall and a peripheral side wall extending upwardly therefrom circumscribing an upper chamber and terminating in an open top end having a rim, and one-way valve means disposed between said upper chamber and said lower chamber for conducting air from said upper chamber; placing an empty flexible trash can liner in said upper chamber and fitting its open end over said rim; and moving said inner receptacle relative to said outer base member to increase the volume of said lower chamber relative to the volume of said upper chamber to extract air trapped between exterior surfaces of the empty liner and interior surfaces of said upper chamber and create a vacuum therebetween sufficient to eliminate air pockets and billowing and draw the empty liner against said interior surfaces in a full open position.
