Disposable swab article
This invention relates to disposable swab articles and other like packages comprising an applicator package having distal ends and having a foam applicator pad and a backing member adjacent thereto. The backing member has at least one reservoir and being formed of a relatively rigid, flat sheet material and a formed material for containing the contents of the reservoir therebetween. The flat sheet material has a slit or weakened portion in the surface of the material and the slit or weakened portion is transversely disposed of the flat sheet material, so that the slit or weakened portion is ruptured upon forcing the distal ends toward each other about the slit or weakened portion. The contents of the reservoir are thereby released into the foam applicator pad upon pressure deforming the formed material containing the reservoir.
