Summary for Patent: 6,536,975

Title: Liquid applicator with opposed wings
Abstract:A liquid applicator for applying a desired liquid to a surface includes an elongated closed ampule formed of a frangible material containing the desired liquid; a flexible elongated hollow body having axially opposed open and closed ends and presenting a central longitudinal axis, the body defining an internal chamber which is adapted to receive the ampule; and a porous element sealed to the body and closing off the open end thereof so that liquid flows through the element when the ampule is fractured. The body includes a pair of diametrically opposed wings projecting therefrom which form gripping members that are spaced from the body and supported for pivoting movement relative thereto. The body also may include structure for fracturing the ampule, the structure being interposed between the body and the gripping members. Upon squeezing the gripping members toward one another, the structure flexes the body inwardly to exert a fracturing force against the ampule. The body also includes a flange protruding from the body at the open end thereof upon which the porous element is supported.
