Pinch Economic Umbra Soap Pump

Unlike conventional soap pumps, this innovative design requires pinching part 2 to dispense soap. When squeezed, the high-elasticity rubber in part 2 inflates again, drawing soap from part 1 through an internal valve. The resulting volume change and pressure cause part 1's thin plastic to shrink. For refills, simply tear the top of part 1 and utilize the built-in hanger for easy carrying.
