Abstract

A fluid tank assembly for use with a vacuum cleaner includes a tank and a spray nozzle interconnected with the tank by a tube. The assembly is adapted to be mounted on a suction nozzle of the vacuum cleaner.

Claims

1. A fluid tank assembly, comprising:

a tank having a main body and first and second side walls adapted to matingly engage a first main surface and first and second side surfaces, respectively, of a vacuum cleaner nozzle;

a manually operable spray nozzle mounted on a second main surface of the vacuum cleaner nozzle opposite the first main surface; and

means for interconnecting the tank and the spray nozzle such that fluid stored in the tank is delivered through the interconnecting means and the spray nozzle.

2. The fluid tank assembly of claim 1, wherein the interconnecting means comprises a tube.

3. The fluid tank assembly of claim 1, wherein the tank includes a fill opening and a cap removably disposed in the fill opening.

4. The fluid tank assembly of claim 1, wherein the spray nozzle includes a trigger which is reciprocable to pump fluid out of the spray nozzle.

5. The fluid tank assembly of claim 1, wherein the side walls of the tank include inner surfaces in contact with the first and second side surfaces that diverge away from one another toward an inlet end of the vacuum cleaner nozzle.

6. A fluid tank assembly, comprising:

a tank having a main body and first and second side walls adapted to matingly engage a first main surface and first and second side surfaces, respectively, of a vacuum cleaner nozzle wherein the side walls of the tank include inner surfaces in contact with the first and second side surfaces that diverge away from one another toward an inlet end of the vacuum cleaner nozzle;

a manually operable spray nozzle mounted on a second main surface of the vacuum cleaner nozzle opposite the first main surface; and

a tube interconnecting the tank and the spray nozzle such that fluid stored in the tank is delivered through the interconnecting means and the spray nozzle.

7. The fluid tank assembly of claim 6, wherein the spray nozzle includes a trigger which is reciprocable to pump fluid out of the spray nozzle.

8. The fluid tank assembly of claim 7, wherein the tank includes a fill opening and a cap removably disposed in the fill opening.

9. The fluid tank assembly of claim 6, wherein the side walls of the tank are undercut to accommodate flanges of the side surfaces of the vacuum cleaner nozzle.
