Abstract
The sponge has a flat washing surface and a round back. It is shaped so as to minimize the bending of the fingers when gripping it, thus facilitating its use by people with arthritic or crippled hands. The sponge also has a notch for a finger to fit into. This makes the sponge easier to grip and control, and allows the application of greater scrubbing pressure to a small area by applying finger pressure against a thin section of sponge material at the end of the notch. This facilitates washing crevices of the body and other difficult-to-reach surfaces. Although the sponge can be used for a wide variety of washing jobs, it is especially useful as a bath sponge. Preferably, the sponge is made of fully-reticulated polyurethane foam, and is formed by compressing a thick sheet of foam against a plate with a shaped hole or cavity in it, and slicing off the protruding mass of material.
