ABSTRACT:
A fluid container and dispenser including an elastomeric reservoir and a dispensing tube connected thereto and a valve to either allow or inhibit fluid flow into or out of the reservoir. One embodiment includes an elongate tube with a hole in one side and an elastomeric sleeve surrounding a portion of the tube. A sliding valve element is mounted in the tube to close the hole. The valve element is mounted on a second, smaller tube which slides within the first-mentioned tube. The sleeve is filled by sliding the valve element away from the hole and injecting fluid under pressure into the sleeve to expand it. The valve then is slid to its closed position. The combined first-mentioned and second tubes together form a straw to withdraw fluid from a secondary container into which fluid may be dispensed.
