Japanese Patent JPH063360
Kind Code:
U
Abstract:
A variable-weight playball whose outer casing (10) is formed of liquid-impervious, flexible material, having closable port (14) therein. Confined within the casing (10) is a compressible body (11) having the same configuration which depends on whether the ball is spherical or in some other shape. The body is formed of low-density, open-cell, flexible foam plastic material having sponge-like properties. To impart heft to the ball, water is introduced through the port (14) into the body and absorbed thereby, the port then being closed to retain the water. To thereafter lighten the ball, the port is opened and the ball is squeezed to discharge water through the port until the ball has the desired reduced weight, after which the port is closed. The casing may be contoured, printed or otherwise arranged so that the ball simulates the head of a humanoid or animal-like character having a mouth. The port (26) of the casing is integrated with the mouth of the character so that when water is added to the ball, it is seemingly introduced through the mouth.
