Abstract: A disposable plunger has a force cup and a handle removably coupled to the force cup. One end of a pliable, waterproof sleeve is sealed to the force cup and is coiled to form an annulus. Following coupling of the handle to the force cup the sleeve may be uncoiled so as to encircle a selected length of the handle. When the force cup and a portion of the handle are immersed in liquid, the sleeve prevents the liquid from contaminating the handle. When the need for the plunger has ended, the handle may be uncoupled from the force cup and the latter discarded together with the sleeve.
