ABSTRACT:
A fountain applicator includes a flexible polyurethane foam head having cemented to its top face a frangible film to which is cemented along its border an upwardly directed liquid reservoir having a bottom opening and divided into a pair of compartments by a pair of medial panel walls converging downwardly to a transverse apex. The film may be ruptured selectively by controlled pressing the film against the apex by pressing in the sponge head. In another form the medial conveying walls are united and a central opening is formed in the film which need not be frangible and has a passageway between the sponge head and the film extending between the opening and the edge of the reservoir. A flexible band extends along the passageway and has its inner end folded under and joined to the border of the opening by pressure sensitive adhesive.
