Abstract A disposable liquid applicator is provided in which the liquid to be dispensed is carried within a prescored container. Absorbent material is fastened to the container overlying the prescored portion. The container and the absorbent material cooperate to cause the liquid to be dispensed into the absorbent material when the container is bent away from the prescored portion and about itself.
