ABSTRACT:
A disposable self-contained liquid applicator having a rupturable membrane for sealing a container for liquids, an absorbent applicator overlying the membrane for receiving the liquid from the container when the membrane is ruptured, and a member underlying the membrane for producing a rupturing surface and for penetrating the membrane upon actuation by a force applied to the outside of the applicator. The member underlying the membrane includes two integral planar sections inclined from each other and intersecting to define a bending line and at least one serrated slit formed in at least one of the sections along the bending line under the rupturable membrane. The serrated slit has teeth-like edges in the plane of at least one of the sections for forming the rupturing surface and for penetrating the membrane when the edges are moved outwardly against the membrane. The planar sections having outer flange portions extending away from the container which are manually movable downwardly and inwardly toward the container for producing the teeth-like edges from the plane of the sections and for moving the edges outwardly against the membrane.
