ABSTRACT:
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.
