Container cleaner

1. A container cleaner comprising:

a body having a fluid inlet;

a fluid passage in communication with the fluid inlet and extending within the body; and

a nozzle assembly comprising:

a spray head having a first opening connected to the body and in fluid communication with the fluid passage, and a second opening;

a plunger protruding through the second opening and moveable between a first position and a second position;

a stem extending from the plunger, the stem comprising a base portion; and

a stopper having an opening therein and configured to receive the at least a portion of the stem therethrough,

wherein the base portion is configured to receive fluid pressure from within the fluid inlet, and in response to receiving the fluid pressure, form a seal with the stopper between the spray head and the body without using a biasing member; and

wherein the plunger operatively moves to the second position in response to receiving mechanical pressure that is greater than the fluid pressure received by the base portion.

2. The container cleaner of claim 1 , wherein the body comprises a base.

3. The container cleaner of claim 1 , wherein the nozzle assembly includes a threaded portion engaged with a threaded portion of the body.

4. The container cleaner of claim 1 further comprising an o-ring positioned between the spray head and the body.

5. The container cleaner of claim 1 , wherein the area of the stopper opening is less than 0.5 square inches.

6. The container cleaner of claim 5 , wherein the area of the stopper opening is 0.2 square inches.

7. The container cleaner of claim 1 further comprising one or more fins protruding from an exterior surface of the body.

8. A container cleaner comprising:

a body having an exterior wall and including a fluid inlet;

a fluid passage in communication with the fluid inlet and extending within the body; and

a nozzle assembly comprising:

a spray head connected to the body and in fluid communication with the fluid passage, the spray head including an opening;

a plunger protruding through the opening at a distal end of the spray head and moveable between a first position and a second position;

a base portion protruding from the plunger;

a stopper having an opening therein and configured to receive a portion of the plunger; and

at least one aperture in the spray head, wherein the aperture is arranged at an angle between 90 degrees and 180 degrees with respect to the exterior wall of the body,

wherein the fluid inlet operatively receives a pressurized fluid and wherein the base portion receives pressure from the fluid to bias the plunger in the first position without using a spring; and

wherein the plunger operatively moves to the second position in response to receiving mechanical pressure that is greater than the pressure of the pressurized fluid received by the base portion.

9. The container cleaner of claim 8 , wherein the at least one aperture is arranged at an angle of 160 degrees with respect to the exterior wall of the body.

10. The container cleaner of claim 8 , wherein the stopper is positioned to seal the connection between the spray head and the body.

11. The container cleaner of claim 8 , wherein the stopper has an L-shaped cross-sectional shape.

12. The container cleaner of claim 8 , wherein the container cleaner includes four apertures in the spray head.

13. The container cleaner of claim 8 , wherein the plunger is capable of forming a seal with the opening in the spray head when the plunger is in first position.

14. The container cleaner of claim 8 further comprising a slot in the exterior wall of the body configured to receive an o-ring therein.

15. The container cleaner of claim 1 , wherein the spray head does not include a biasing member that exerts pressure on the base portion.

16. The container cleaner of claim 1 , wherein at least a portion of the plunger is configured to extend from spray head in the first position.

17. The container cleaner of claim 16 , wherein the plunger is further configured to displace the base portion in response to at least the portion of the plunger receiving pressure.

18. A container cleaner comprising:

a body comprising a fluid passage formed therethrough; and

a nozzle assembly comprising:

a spray head engagedly connected to the body and in fluid communication with the fluid passage, the spray head comprising:

a first opening proximal to the fluid passage and a second opening distal to the fluid passage;

a cavity disposed between the first opening and the second opening;

a plunger at least partially disposed through the cavity;

a base portion extending from the plunger; and

a stopper disposed between the cavity and the fluid passage, the stopper comprising an aperture configured to receive a portion of the plunger;

wherein, in response to fluid pressure, the base portion forms a seal with the stopper without a spring biasing the base portion; and

wherein the plunger operatively brakes the seal between the base portion and the stopper in response to receiving mechanical pressure that is greater than the fluid pressure received by the base portion.

19. The container cleaner of claim 18 , wherein at least a portion of the plunger extends from the second opening when the base portion forms a seal with the stopper.

20. The container cleaner of claim 19 , wherein at least the portion of the plunger is translatable about an axis of the container cleaner and wherein translation of the plunger breaks the seal.
