Abstract
A self closing squeeze valve comprising a resilient and deformable valve body having a cavity into which a wafer made of closed cell foam with a smooth surface is permanently inserted, causing a normal state of blockage and seal. Lips are provided across the opposing broad surfaces of the cavity, aligned normal to the direction of flow through the valve, to augment sealing by the wafer. Manual pressure on the valve body causes both components to deform to form a passage allowing flow through the valve.
