Abstract
An improved applicator device is disclosed for applying an applicator material such as a liquid or a flowable solid to a surface. The device comprises a material container and a surface applicator for applying the applicator material to the surface. A valve having a valve element is interposed between the material container and the surface applicator to permit the flow of applicator material to the surface applicator when the valve element is in an open position and to inhibit the flow of applicator material to the surface applicator when the valve element is in a closed position. The valve includes a valve closure having an internal closure cavity with a first end being connected to the material container and with a second end defining a surface applicator opening therein. The valve element has a distal end portion which extends through the applicator opening of the valve closure when the valve element is biased into the closed position. The surface applicator comprises the distal end portion of the valve element cooperating with the applicator opening when the distal end portion of the valve element is pressed against the surface thereby forming an annular opening for the flow of…
