Patent ID: 6886807

Claim:
A bite valve for drinking liquids from a hydration system, said bite valve comprising: a hollow deformable impervious body having a receiving opening fluidically connectable to an outlet of the hydration system for receiving liquids and a dispensing opening adapted to selectively dispense received liquids; a resilient piston positioned within said hollow deformable body, said resilient piston comprising a plug normally blocking said dispensing opening, and a resilient bifurcated member having longitudinal dimension and lateral dimension, adapted to shorten its initial predetermined longitudinal dimension when a lateral force is exerted on its lateral dimension, and regain its initial longitudinal dimension when the lateral force is not exerted; a restraining member is provided inside the body, limiting the biting portion of the valve to a portion near the dispensing opening, thus facilitating better performance of the valve, whereby when a lateral force is exerted on said resilient bifurcated member the piston is retracted inwardly thus allowing liquid to flow through said dispensing opening.
