PUMP FOR DISPENSING FLUIDS

摘要

A pump (300) for dispensing a fluid product from a product container (200), comprises a unitary pump body (500) defining an axis and comprising a pump chamber (510), a pump inlet (502) and a pump outlet (504). The pump chamber (510) is collapsible over an axially directed pumping stroke from an initial condition to a collapsed condition and is biased to return to its initial condition in a return stroke. An axially compressible spring (400) is arranged to at least partially support the pump body (500) during its collapse.
