Abstract
A bite valve () comprises an outer barrel () of low-friction, soft but durable, laterally-compressible material and a rigid axially moveable inner stem (). Closing the valve urges the distal face of a stem-mounted gasket () distally against the sharpened tubular proximal end of a barrel-embedded flanged rigid sleeve () through which fluid passes. The stem is continually urged distally by captive compression spring () which pushes proximally against sleeve () and distally against a cap () mounted on the stem's distal end. When a user bites the barrel's indented exterior bite zone (), two opposing sides of a conical surface () inside the barrel contact and slidably urge the stem proximally, pulling the gasket away from the sleeve end, thereby opening the valve. After drinking, a user releases their bite, allowing the spring to again move the stem distally, pushing the gasket back into a (default) sealing condition pressed against the sleeve's sharpened proximal end.
