ABSTRACT:
An apparatus for holding a flexible, collapsible trash liner. A rigid upward vented trash receptacle receives a flexible, collapsible, trash liner and includes along the side walls of the upward vented trash receptacle a plurality of axially aligned and peripherily positioned hollow tubes which are interior to or part of (molded into) the vented trash receptacle's internal walls and open at both ends which terminate approximately 1" interior to the top and bottom of the upward vented trash receptacle. The hollow tubes allow ambient air to be drawn from the top of the tubes to the bottom of the tubes to reduce the vacuum created in the vacant space immediately below the flexible, collapsible trash liner as it is removed from the upward vented trash receptacle and thus facilitate removal of the flexible, collapsible trash liner. At the same time the upward vented trash receptable will contain leakage of most trash or other material even if the flexible collapsible trash liner breaks as well as most trash or other material without a flexible, collapsible trash liner installed. Since the top portion of the installed flexible, collapsible trash liner is normally just loosely folded over the upper rim of the upward vented trash receptacle, notches placed in the upper rim of the receptacle assist the vented tubes and allow some of the air trapped between the flexible, collapsible trash liner and the interior of the upward vented trash receptacle to more freely escape as the flexible, collapsible trash liner is filled with most trash or other material. A lid is provided for closing the top opening of the upward vented trash receptacle.
