Abstract
An applicator is adapted to be mounted on a hollow piston stem of a manually reciprocable pump dispenser for applying a cleaning liquid to a fibrous article such as fabric, rug or carpet or the like from a container of liquid to which the dispenser is mounted. The applicator has a domed outer convex rigid wall with at least one discharge port in communication with the discharge passage of the piston stem, and an outer surface of the domed wall is textured for rubbing the cleaning liquid into the fibers article during a cleaning operation. An overcap is connected to a side wall of the applicator by a hinge permitting the overcap to cover the outer surface of the domed wall when not in use. And, a container closure may be provided in telescoping relationship to the applicator which is rotatable about its central axis between lock and unlock positions.
