ABSTRACT:
A reusable sealing cap for bottles of the type having a flat radially extending circular flange on the neck of the bottle spaced below the top edge of the mouth of the bottle. The reusable cap is removeably received on the open mouth of the bottle and partially surrounds the upper neck portion of the bottle. The cap member carries a resilient seal which fits over the open mouth of the bottle to sealably enclose the open mouth of the bottle. A movable spring wire lever member is pivotally mounted on the cap and bent in a configuration to form a flange engaging portion to be slidably received and biased beneath the circular flange in the sealing position and a pair of laterally opposed arcuate portions which create spring tension to create a compressive force between the cap and the circular flange sufficient to compress the resilient seal and effect a liquid tight seal on the open mouth of the bottle when the flange engaging portion is biased beneath the circular flange. The lever configuration includes a pair of smaller arcuate portions cooperative with the lateral arcuate portions to provide additional compressive force in the sealing position. The lateral arcuate portions also serve as a finger receiving handle for carrying the bottle.
