PLUNGER FOR PLUMBING FIXTURES

摘要

An improved plunger having a true arch configuration and defining an interior cavity provides a body having a convexly dome shaped upper portion and a rectilinear truncated conic shaped bottom portion that defines a bottom orifice. Axial downward pressure exerted or a handle communicating with a handle attachment carried by the dome shaped upper portion causes the body to collapse to forcefully expel contents of the interior cavity outwardly through the bottom orifice and into a pipe or plumbing fixture. A flexible resiliently deformable exterior lip circumscribing the bottom orifice prevents leakage and the truncated conic shape of the bottom portion fluidically seals a toilet siphon jet to prevent loss of plunger pressure when removing clogs and obstructions.

主权项

1. A forcibly collapsible plunger comprising:
a resiliently deformable body having a closed top portion, and a lower portion defining a bottom orifice; the top portion of the body and the lower portion of the body interconnected to one another along adjacent edge portions to define an interior cavity communicating with the bottom orifice; the top portion of the body defines a first cavity having a first volume; the lower portion of the body defines a second cavity having a second volume, and wherein the second volume is less than the first volume; a resiliently deformable exterior lip circumscribes the bottom orifice and bottom portion sidewalls extend generally upwardly and outwardly from the resiliently deformable exterior lip to interconnect with a bottom edge of the body top portion wherein the first cavity and the second cavity form the interior cavity; and axial downward pressure exerted on the resiliently deformable body causes the top portion of the resiliently deformable body to be forcible collapsed downwardly into the second cavity which responsively forcibly expels contents of the interior cavity through the bottom orifice.
