Abstract
An improved bite valve for use in personal hydration devices and other water dispensing systems. The valve has a flexible conduit sealed at an end by a cap. Fluid is blocked from flowing out of the conduit by the cap. The cap provides a fluid seal as a ring around an exterior surface of the conduit. Biting an end of the conduit, near the cap, radially separates the conduit from the cap, permitting fluid to flow into a person's mouth. The configuration of the valve permits a larger valve opening, and correspondingly improved fluid flow through the valve. A positive stop mechanism, to prevent undesired fluid flow, may also be provided in a valve.
