ABSTRACT:
A self-closing push-pull top for a bottle includes a threaded collar adapted to engage a threaded bottle neck. A hollow stem extends from the threaded collar and engages a cylindrical guide aperture of a cap. The cap is slidable along the hollow stem about the guide aperture to a first position in which the hollow stem and the cap are positioned with respect to one another to prevent fluid flow from the bottle. The cap is further slidable along the hollow stem about the guide aperture to a second position in which the hollow stem and the cap are positioned to allow fluid flow therethrough. A biasing member is provided for biasing the cap in the first position. Since the cap is biased in this first position, it normally remains closed. Upon application of working pressure, the biasing member deforms to allow the cap to slide to the second position in which fluid may be dispensed from the bottle. Once the working pressure is removed, the biasing member urges the cap back to the first position thereby closing the top to prevent further fluid flow from the bottle.
