ABSTRACT:
A grip demoisturizing device for a sports racquet, or the like, has a normally closed tubular container containing a moisture absorbing powder and a self-closing, elastically yielding flap valve for admitting the grip into the container. A described embodiment has an apertured tubular partition located coaxially within the container and spaced therefrom by apertured discs, with powder being stored in an annular region and the diameter of the partition being chosen so as to provide a "pump" and "swab" action to provide an additional measure of neatness in dispensing the powder onto the grip.
