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.

1. An apparatus for extracting contents from a refill pouch, comprising: a holding member for holding a refill pouch with its extraction port facing downward; and a pump attached to the extraction port of the pouch, the pump comprising 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 and acts to open and close the inlet opening so that the contents can be introduced into the housing space from the pouch, an outlet-side valve which acts to open and close the outlet opening so that the contents in the housing space can be discharged, a nozzle that communicates with the outlet-side valve for discharging the contents contained in the housing space when the outlet-side valve is open, a support shaft inserted into the housing space and having an upper cylindrical portion and a lower cylindrical portion, the upper cylindrical portion being provided with the inlet-side valve and the lower cylindrical portion being provided with the outlet-side valve, and the pump body having a pump wall portion constituted by a resiliently compressible, restorable and flexible material so that the contents in the housing space can be extracted through the nozzle by compressing the pump wall portion thereby pressurizing the housing space, wherein the inlet-side valve comprises a ball valve having a ball on the housing space side, and the outlet-side valve comprises a valve stem having a valve element which engages with a valve seat of the outlet opening, a spring which urges the valve stem in such direction to press the valve element to the valve seat, and a knob that is connected to the valve stem and that extends outside of the nozzle to enable manual movement of the valve stem from outside the pump. 2. An apparatus for extracting contents from a refill pouch, comprising: a holding member for holding a refill pouch that has an extraction port at a bottom portion of the pouch; and a pump attachable to the extraction port of the pouch for extracting the contents from the pouch, the pump having a pump body that defines a housing space having an inlet opening and an outlet opening, an inlet-side valve that communicates with the extraction ort and that opens and closes the inlet opening so that the contents in the pouch can be introduced into the housing space, an outlet-side valve that opens and closes the outlet opening so that the contents in the housing space can be discharged through the outlet opening, a support shaft disposed in the housing space and having at each end portion thereof a connection portion that connects the support shaft to the pump body, one connection portion being provided with the inlet-side valve and the other connection portion being provided with the outlet-side valve, and the pump body having a wail portion that is made of resiliently compressible material and that is configured to be manually grasped and squeezed in a sidewise direction of the pump body to contract the pump body and pressurize the contents in the housing space to thereby discharge the contents through the outlet opening and that expands to its original shape when the squeezing is discontinued to create a vacuum suction in the housing space to suck contents from the pouch through the inlet opening into the housing space, wherein the other connection portion has a tubular shape, and the outlet-side valve comprises a valve stem movable into and out of engagement with a valve seat to close and open the outlet opening, a spring that urges the valve stem into engagement with the valve seat when the pump body is not being squeezed, the valve stem and the spring being disposed inside the other tubular connection portion, and a manually graspable knob that is connected to the valve stern and that extends outside the pump body to enable manual movement of the valve stem from outside the pump body.
