Abstract

A liquid applicator is provided which is particularly useful in applying preoperative surgical scrubs or paints to skin. The article is provided with an inner layer of flexible porous material and an outer layer of open cell foam sponge material. The flexible, porous layer regulates the flow of liquid therethrough to provide acceptable wetting of the foam sponge while preventing dripping therefrom. The applicator includes a means of maintaining atmospheric pressure within the applicator while the liquid is being dispersed.
