Device for applying liquid materials to the skin, said device having a liquid container, a poromeric plastic applicator head, and a diaphragm spring, and an impervious sleeve holding the applicator in said device. The applicator head fits over the impervious sleeve. The diaphragm spring provides a liquid tight seal between the impervious sleeve and the liquid container and also allows movement of the sleeve and 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. |
