A refillable dispenser and refill cartridge is described for dispensing a product through a pumping mechanism that draws product from the cartridge. Product is pumped upwards from the refill cartridge through a connector tube, across a one-way check valve into a collecting chamber from which it is dispensed through a one-way monitoring valve and exits a nozzle. Flow is initiated by compression of a domed elastomeric wall covering the collecting chamber.

[ What is claimed is:] [1.] A refillable pump dispenser comprising:(i) a container having a first and second end storing a pumpable product;(ii) a pump means for drawing the product from the container and dispensing same, the pump means being positioned over the first end of the container and comprising:(a) a connector tube with upper and lower ends, the lower end of the connector tube having a sharpened mouth which traverses a longitudinal axis of the connector tube at an acute angle;(b) a collecting chamber for receiving product drawn upward from the connector tube;(c) a one-way check valve interposed between the upper end of the connector tube and the collecting chamber;(d) an elastomeric wall at least partially positioned over and communicating with the collecting chamber, the elastomeric wall being resiliently pressable thereby compressing the collecting chamber;(e) a dispensing member communicating with the collecting chamber having an exit orifice through which product can flow outward;(f) a one-way monitoring valve downstream from the collecting chamber controlling the outward flow through the dispensing member; and(g) a refill cartridge positioned within the container, the cartridge having a dispensing end communicating with the connector tube and through which product is drawn, the refill cartridge comprising a collapsible pouch having annular fitment across a dispensing opening of the pouch for securing walls of the pouch thereto, the annular fitment including a cone receptacle extending upward from a top surface of the annular fitment, the cone receptacle having a central recess with sidewalls configured in a taper ranging from 0.5.degree. to 5.degree., and a frangible septum stretching across a full bore of the central recess along the taper to seal contents of the pouch.
