Abstract: 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.
