Liquid dispenser and cleaner

1. A dispenser for applying a cleaning liquid to a fibrous article such as fabric, carpet, or rug, from a container of the liquid, comprising a manually actuated pump having a hollow piston stem defining a discharge passage, an applicator mounted on said piston stem for reciprocation together therewith, said applicator comprising a domed outer rigid wall having at least one discharge port in communication with said discharge passage to permit the liquid to flow on to an outer surface of said wall upon reciprocation of said applicator, and said domed outer wall having a textured outer surface for rubbing the liquid into the fibers of the article during a cleaning operation, wherein said applicator has a cylindrical sidewall connected to said domed wall, and an overcap hinged to said sidewall and pivotable in a first direction for covering said domed wall in a condition of non-use of the dispenser, said overcap being pivotable in a second opposite direction for substantially exposing said applicator to enable said applicator to contact the fibrous article without intereference from said overcap, and wherein lock means is provided for locking the actuator in a condition of non-use of the dispenser, the applicator having a depending cylindrical sidewall in telescoping relation to an upstanding cylindrical skirt of the lock means, axially extending rib and groove means acting between the sidewall and the skirt for locking and unlocking the applicator relative to the skirt upon applicator rotation about a central axis thereof.

2. The dispenser according to claim 1 , wherein the overcap is connected to the sidewall by an over-the-center hinge for maintaining the overcap in an uncovered position during use of the dispenser, and for maintaining the overcap covered over the domed wall during non-use.

3. The dispenser according to claim 1 , wherein said domed outer wall is provided with a plurality of spaced hemispherical projections comprising said textured surface.

4. An adaptor for applying a cleaning liquid to a fibrous article such as fabric, rug or carpet from a container of the liquid, comprising an applicator adapted to be mounted on a hollow piston stem of a manually reciprocable pump dispenser, the applicator having a domed outer convex rigid wall having at least one open discharge port for directing liquid to an outer surface of said domed wall, said outer surface being textured for rubbing liquid into the fibers of the article during use, the applicator having a cylindrical side wall to which the domed wall is connected, and an overcap connected to the sidewall by a hinge permitting the overcap to be pivoted in a first direction to cover the outer surface of the domed wall during non-use, said overcap being pivotable in a second opposite direction for substantially exposing said applicator to enable said applicator to contact the fibrous article without intereference from said overcap, wherein the hinge comprises an over-the-center hinge capable of maintaining the overcap in open and closed positions relative to the domed outer surface, said adaptor further comprising a container closure in telescoping relationship to the applicator for relative reciprocating movement, the applicator being rotatable about a central axis thereof, lock means acting between the applicator and the closure preventing movement of the applicator toward the closure in at least one selected rotary position of the applicator, wherein the lock means comprises an axial rib on one of the applicator and the closure and an axial groove on the other of the applicator and the closure, the rib providing a stop preventing the movement in the one rotary position.

5. The adaptor according to claim 4 , wherein the textured outer surface comprises a plurality of spaced hemispherical projections.
