Abstract

The present toilet and sink drain plunger seals either around or in a toilet or sink drain hole despite the hole's size, configuration and location. The plunger includes an elongated upstanding handle connected to the top of a depending, preferably frusto-conical, open bottomed bellows in the sidewalls of which are formed a vertically stacked series of interconnected horizontal pleats. The plunger further includes a series of toilet drain hole seals connected to each other and to the bottom of the bellows to form a unitary whole depending below the bellows. The seals are of progressively smaller size from the uppermost to the lowermost and all feature inwardly and downwardly curved sealing surfaces. The seals are rings or doughnuts molded into the plunger body. The bottommost seal bears a short vertical small diameter annular wall depending therefrom and which acts both as a seal and a seat for the plunger. The entire plunger can be formed in a single plastic molding operation or, if desired, in separate molding operations for the handle and remainer of the plunger. The plunger is efficient, light in weight, inexpensive and durable.
