Abstract:

Device for applying liquid materials to the skin, said device having a liquid container, a poromeric plastic applicator head, and a diaphragm spring holding the applicator in said device. The diaphragm spring provides a liquid tight seal between the poromeric applicator head and the liquid container and also allows movement of the poromeric applicator head in a vertical direction to create a pressure within the liquid container and provide force to aid in moving the liquid through the poromeric applicator head to its outer surface. The poromeric applicator head is also provided with a capillary pressure compensating valve to maintain substantially equal pressure within and without the dispensing container.
