<p>A refillable dispenser (2) and refill cartridge (48) is described for dispensing a product through a pumping mechanism that draws product from the cartridge (48). Product is pumped upwards from the refill cartridge (48) through a connector tube (12), across a one-way check valve (16) into a collecting chamber (14) from which it is dispensed through a one-way monitoring valve (22) and exits a nozzle. Flow is initiated by compression of a domed elastomeric wall (18) covering the collecting chamber (14).</p> |
