ABSTRACT:
A bite valve for delivering liquid to the mouth of an individual includes a hollow body portion and a deformable closure connected to the body portion. A plurality of spaced slits are formed in the deformable closure. A portion of the deformable closure between the slits changes shape when the bite valve is subjected to opposed compressive forces. This causes the portion of the deformable closure to change shape and the slits to open and form a plurality of openings allowing liquid flow through the deformable closure.
