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 therebetween. A hollow vertical hollow spout tapers upwardly and outwardly from the disc and has an open lower end coincident with the second opening. The spout has an upper open end defining a first slot therein, the upper end being smaller in area than the lower end. A hollow member is disposed within the spout with an upper open end coincident with the upper end of the spout, the member extending downwardly and inwardly from the upper end of the spout to a lower end horizontally aligned with the lower end of the spout. The lower end of the member has a second slot smaller in area than that of the first slot.
