Apparatus with at least one replaceable receptacle element and a base with elevating means for raising the at least one replaceable receptacle element

Abstract

An apparatus has a base having a side that defines an interior space, and a periphery that defines an aperture above the interior space. A bowl element has a rim and is shaped to fit into the interior space such that the rim abuts the periphery. A lever mechanism has a lever, a fulcrum having an aperture, a pair of ears on opposite sides of the aperture, pins extending from each of the pair of ears into the lever for pivotally mounting the lever on the fulcrum, and an attachment element for attaching the fulcrum to the base. The lever has a proximal end adapted to abut the bowl element, and a distal end opposite the proximal end.

1 . A method for using an apparatus for placing and raising at least one removable and replaceable receptacle bowl element or liner, the method comprising:
 placing a bowl element with a rim, an underside, an interior surface, at least one side wall, and an exterior shape, in a base having at least one side with an exterior and an inside, a bottom, a top having a periphery and an aperture, an interior space, and an elevating means for raising the bowl element from the base;   inserting the underside of the bowl element through the aperture at the top of the base and the underside of the bowl element is located within the inside of the base;   supporting, at least in part, the rim of the bowl element by the periphery of the top of the base;   contacting the rim, underside, or at least one side wall of the bowl element; and   raising, with an elevating means, the bowl element from the base.
