ABSTRACT:
A reusable closure device which is especially intended for use on conventional 18.9 liter plastic bottles in common use for supplying bottled drinking water. The device includes a plastic cap with a replaceable resilient seal. A pair of levers are mounted on the cap for pivoting movement between a first position which allows the cap to be placed on or removed from the bottle and a second position in which cam surfaces on the proximal ends of the levers engage a groove in the neck of the bottle to press the cap down on the bottle. The levers are approximately L-shaped and legs of the levers containing their distal ends interengage in the second position to form a carrying handle. At the present time, the abovementioned bottles are provided with non-reusable heat-shrink plastic caps which are discarded by users resulting in environmental waste. The present invention eliminates this waste.
