66239-1213 IMPROVED TOILET BOWL PLUNGER ABSTRACT OF THE DISCLOSURE The plunger includes an elongated knurled handle, a base sealing member having a central aperture extending there- through, and a multi-pleated bellows preferably releasably connec- ted to the bottom of the handle and preferably permanently connected to the top of the base sealing member. Preferably, the bellows and base sealing member are generally cylindrical and of rubber, plastic or the like. They may be integral. The sealing member may have an upper bowl sealing rim with a collapsable top wall adapted to receive the bellows, and a small diameter lower sealing ring, with depending skirt. Preferably, the transverse bellows pleats increase in diameter from the bellows top to bottom and may be arranged in sets for improved seating. The handle top can be removable and the handle can contain a central cavity extending longitudinally therethrough, which cavity can, if desired, be threaded to receive a garden hose. Thus, the handle top when unscrewed can act as a vacuum relief valve. The handle top can also include a padded transverse grip. The device is highly efficient and durable and is adapted for use in a variety of applications.
