Abstract
A liquid dispensing pouch in which a support, a liquid impregnated pad, permeable membrane and cover layer are peripherally joined in a layered arrangement by adhesive or heat seal means. The layers are coextensive and the impregnated pad is contoured to provide enhanced liquid-holding capabilities. The liquid is dispensed by peeling off the cover layer and bringing the membrane surface into contact with the skin.
