My invention is a reusable cup which takes the form of an annular bracelet or wristlet. 

This would be made of injection-moulded plastic (like normal 'throwaway' plastic cups). 

This design can be conveniently slipped on one's wrist (by opening the gap a little) and worn under a shirt cuff when empty, so that it�s always available. 

A bigger variant could be worn on one's ankle.

It would be slipped off and the annulus filled with beverage. Two such bracelet cups might be nested so that the outer acted as insulation for the liquid-filled inner. A lip is provided to enable easier drinking.

This design would be stable and unlikely easily to be knocked over in use. It would also fit existing cup holders.

To clean the cup after use, a string is attached through another lip in the base (not shown). This allows the cup to be whirled around (outside) in order to drive all liquid from the cup and air dry it for reuse.

It could be cheaply manufactured and carry a variety of sponsors' messages (perhaps printed on the inside surface of a transparent cup). Such messages could help to form communities, like those created by the use of charity wristbands. The cup could even be decorated and worn as a form of anti-adornment 'statement' jewellery in support of good causes such as environmental protection.
