SPECIFICATION Abstract The cap is made from rubber or plastic material which has elastic properties. The sizes and configuration are determined by each type of container, thus providing a liquid and air seal. (See Fig. 1, Fig. 2, and Fig. 3 which illustrate three examples, but are not limited thereto.) The cap in- corporates a special valve. This joystick valve provides ac- cess to the contents through a spout, vent lever (joystick), in the "open" position (see Fig. 4). When the valve is in the "closed" position, the contents will be trapped within the vessel (see Fig. 5). The valve is of a ball or disc con- struction. The ball or disc is an integral part of the joy- stick, which also incorporates means of closing the vent. Both seat and vent are part of the cap.
