ABSTRACT:
A closure dispensing device or valve and method which may be applied to a liquid container. The preferred closure device includes a channel body with an extending channel portion. The channel portion has an internal channel with an exit port. The exit port may include a circular seat into which an O-ring may be placed. A spring seal mechanism is placed in tension over the channel portion, the spring seal mechanism having a flat surface for engaging and sealing against the O-ring. To actuate the dispenser, the user moves the leg of the pivoted "U" spring away from the O-ring and allows liquid to pass therebetween. When the user releases the leg, the spring tension provided by the pivoted "U" spring restores the seal between the flat surface of the leg and the O-ring.
