ABSTRACT:
A cap for detachably enclosing an upper open end of a hollow vertical disposable container with liquid therein employs a flat horizontal disc having first and second openings disposed in spaced apart positions therein. The first opening is a pin hole. The second opening is relatively large. The disc has a peripheral socket adapted to engage the periphery of the upper end of the container in such manner that liquid cannot flow out. A hollow vertical hollow spout tapers upwardly from the disc with an open lower end coincident with the second opening. An open upper of the spout is smaller in area than its lower end. A member is disposed within the spout with an upper open end coincident with the upper end of the spout and extends downwardly and inwardly from the upper end of the spout. A lower end of the spout has at least one hole therein. The lower end of the member is disposed intermediate the upper and lower ends of the spout:
the disc, spout and member constituting a single integral unit which when positioned in place on the container will not exhibit any substantial leakage of liquid when the liquid in the container surges therein because of sudden movement of the container or when the container is disposed horizontally on its side:
