Abstract

A system and a tool for clearing an obstructed pipe or drain is presented. The system comprises the tool and a housing. The tool comprises a plunger and a protective sleeve with a closed end. The plunger comprises a dowel shaped flexible portion and a dowel shaped rigid handle portion, the distal end of the rigid handle portion being fixedly attached to the proximate end of the flexible portion by a connection device. The protective sleeve is comprised of a water soluble material that is configured to conform to the shape of the dowel shaped flexible portion and at least a portion of the dowel shaped rigid handle portion when the flexible portion is inserted therein, the water soluble material being chemically formulated and mechanically formed to maintain watertight integrity when submerged in water. The housing is configured to store the plunger and the protective sleeve when not in use.

Claims (33)

1. A pipe clearing system comprising:

a plunger;

a protective sleeve with an open end and a closed end; and

a housing configured to store the plunger and the protective sleeve when not in use,

wherein the plunger comprises a dowel shaped, non-rotatable flexible portion with a proximate end and a distal end and a dowel shaped rigid handle portion with a proximate end and a distal end and a length therein between, the distal end of the rigid handle portion being fixedly attached to the proximate end of the flexible portion by a connection device, and

wherein further the protective sleeve is comprised of a water soluble material that is configured to conform to the shape of the dowel shaped flexible portion and at least a portion of the dowel shaped rigid handle portion when the flexible portion is inserted therein, the water soluble material being chemically formulated and mechanically formed to maintain watertight integrity for at least 15 seconds when submerged in water.

2. The pipe clearing system of claim 1 , wherein the connection device is a screw like groove-and-land connector.

3. The pipe clearing system of claim 1 , wherein the rigid handle portion comprises a gas vent with an inlet and an outlet.

4. The pipe clearing system of claim 1 , wherein one of a width or a diameter of the rigid handle portion varies along its length.

5. The pipe clearing system of claim 4 , further comprises a slidable ring with an inside diameter circumscribing the rigid handle portion, wherein the inside diameter of the slideable ring is smaller than the diameter of the rigid handle portion at least one location along its length.

6. The pipe clearing system of claim 5 , wherein the slidable ring freely slides along the length of the rigid handle portion between its proximate end and the at least one location along its length where the inside diameter of the slideable ring is smaller than the diameter of the rigid handle portion.

7. The pipe clearing system of claim 5 , wherein the inlet of the gas vent is located on the distal side of the at least one location along the length of the rigid handle portion.

8. The pipe clearing system of claim 1 , wherein the housing is defined by a wall with an interior surface, an exterior surface, a top edge, and a bottom edge, the wall having protrusion perpendicularly affixed thereto proximate the top edge, wherein further the protrusion removably couples to the protective sleeve when not in use.

9. The pipe clearing tool of claim 1 , wherein the diameter of the rigid handle is uniform along its entire length.

10. The pipe clearing tool of claim 1 , wherein the diameter of the plunger is uniform along its entire length.

11. A pipe clearing tool comprising:

a protective sleeve with an open end and a closed end; and

a plunger removably inserted into the protective sleeve,

wherein the plunger comprises a dowel shaped flexible portion with a proximate end and a distal end and a dowel shaped rigid handle portion with a proximate end and a distal end and a length therein between, the distal end of the rigid handle portion being fixedly attached to the proximate end of the flexible portion by a connection device, and

wherein further the protective sleeve is comprised of a water soluble material that conforms to the shape of the dowel shaped flexible portion and at least a portion of the rigid handle portion when the flexible portion is inserted therein, the water soluble material being chemically formulated and mechanically formed to maintain its watertight integrity for at least 15 seconds when submerged in water.

12. The pipe clearing tool of claim 11 , wherein the protective sleeve comprises a perforated tab extending above the open end, a perforation in the perforated tab being configured to adjacently couple the plunger and the protective sleeve via one of a hook or peg.

13. The pipe clearing tool of claim 11 , further comprising an elastomeric ring circumscribing the ridged handle portion and slideable along its length, the elastomeric ring having an inside diameter when relaxed.

14. The pipe clearing tool of claim 13 , wherein the proximate end of the rigid handle includes circumferential notch with an upper lip and a lower lip that is sized to releasably capture and hold the elastomeric ring at its inside diameter.

15. The pipe clearing tool of claim 11 , wherein the diameter of the rigid handle portion is not uniform from its distal end to the connection device.

16. The pipe clearing tool of claim 11 , wherein the diameter of the rigid portion decreases from its proximate end to the connection device.

17. A pipe clearing tool comprising:

a protective sleeve with an open end and a closed end; and

a plunger removably inserted into the protective sleeve,

wherein the plunger comprises a dowel shaped flexible portion with a proximate end and a distal end and a dowel shaped rigid handle portion with a proximate end and a distal end and a length therein between, the distal end of the rigid handle portion being fixedly attached to the proximate end of the flexible portion by a connection device and the proximate end of the rigid handle portion having a crossbar attached thereto with two projecting ends, and

wherein further the protective sleeve is comprised of a water soluble material that is configured to conform to the shape of the dowel shaped flexible portion and at least a portion of the rigid handle portion when the flexible portion is inserted therein, the water soluble material being chemically formulated and mechanically formed to maintain its watertight integrity for at least 15 seconds when submerged in water.

18. The pipe clearing tool of claim 17 , wherein the protective sleeve is comprised of a soluble polymer.

19. The pipe clearing tool of claim 18 , wherein the protective sleeve includes two diametrically opposed support holes penetrating the protective sleeve near its proximal end, each commensurate in position with one of the projecting ends of the crossbar.

20. The pipe clearing tool of claim 19 , wherein a thickness of the protective sleeve is greater along a lower length portion of the protective sleeve than the rest of the protective sleeve.
