DISPENSER PUMP

摘要

This invention relates to pump-action nozzle devices methods of making the same. The nozzle devices of the invention comprises a body which defines an internal chamber (700) having an inlet through which fluid may be drawn into said chamber and an outlet through which fluid present in the chamber may be expelled from the nozzle. The inlet comprises an inlet valve and the outlet comprises an outlet valve. Fluid is dispensed from the nozzle devices by applying pressure to a first rigid portion (602a) of the body which causes a second portion (2504) of the body of the device to be resiliently deformed o r displaced so as to enable the chamber to be compressed and fluid present therein to be dispensed. In preferred embodiments, the actuator provides a rigid actuator surface that an operator can apply a pressure to.
