ABSTRACT:
This invention relates to an integrally molded captive cap assembly including a threaded base for attachment to a container and a lead tube which projects into a hollow cap which is pivotally connected to the base. An integrally molded pair of spring members are disposed between the cap and the base and have end portions pivotally connected to the base and to the cap. The spring members bias the cap toward one of two positions. When the cap is in a closed position, the spring members bias the cap toward the closed position and when the cap is opened past an intermediate position, the spring members bias the cap toward an open position.
