Abstract
An apparatus for extracting the contents from a refill pouch comprises a holding member for holding the pouch with its extraction port facing downward, and a pump attached to the extraction port of the pouch. The pump has a pump body defining a housing space having an inlet opening and an outlet opening, an inlet-side valve which communicates with the extraction port to open and close the inlet opening so that the contents can be introduced into the housing space from the pouch, and an outlet-side valve to open and close the outlet opening so that the contents in the housing space can be discharged through a nozzle that communicates with the outlet-side valve. The pump wall portion is constituted by a resiliently compressible, restorable and flexible material so that the contents in the housing space can be extracted through the nozzle by manually squeezing the pump wall portion thereby pressurizing the housing space.
