ABSTRACT:
A rub-on applicator for rubbing liquid onto a surface to be coated. The applicator includes a flexible compressible bottle containing the liquid to be dispensed. The mouth of the bottle is covered by a thin flexible molded diaphragm sealed to the lip of the bottle. The diaphragm is formed with a small, centrally located, permanently open hole. In one embodiment, the diaphragm normally projects concavely under suction forces into the bottle, but is sufficiently flexible that by squeezing and compressing the bottle, the diaphragm will be forced by compression of fluid in the bottle to project convexly outward of the bottle with a broadly rounded outer surface, so that by turning the bottle upside down and squeezing the bottle, liquid within the bottle is forced therefrom onto to a surface to be coated. Since the hole in the diaphragm is permanently open, when the applicator is upright with the diaphragm in its normally inwardly projecting position, any liquid on the outer surface of the diapraghm will flow through the hole into the bottle.
