WATER-ACTIVATING PARTICLE CASING WITH ANNULAR FLOAT
Disclosed is a water-activating particle casing with an annular float, said casing having openings to allow washing water to flow in and out from said casing and contact the water-activating particles contained therein, thereby increasing the cleaning capability of the washing water circulating in a washing vessel. The annular float is of closed cell rubber, surrounding the body of said casing, thereby permitting said casing to float and ride on the swirling circulation of washing water in the washing vessel. Thus, the water-avtivating particles can be effectively exposed to circulating washing water to permit their surface activities to be used to their limit in washing.
