A VALVE AND A PUMP-ACTION DISPENSER DEVICE HAVING SUCH A VALVE

摘要

A valve (45) for controlling the flow of fluid material across the valve comprises a male valve member or projection (44) and a female valve member or recess (42) for receiving the projection. A flow path (77, 88) for the fluid material is defined through the projection (44) or between the projection (44) and the recess (42). The valve also includes a deformable means (90) associated with one of the projection and the recess and which is movable from a first position in which it engages the other of the projection and recess to close off the flow path and a second position in which it is spaced from the other of the projection or recess and the flow path is opened. More than one flow path through the valve may be defined so that the valve can control the flow of fluid materials from two different sources. The valve (45) is particularly suited for use as a pre-compression outlet valve in a pump-action dispenser device (10).
