Abstract

A device for removing an obstruction from a pipe or toilet generally includes a handle portion and a flexible head portion having a plurality of grooves. The flexible head portion is configured for insertion into a pipe. The flexible head portion is configured by shape and/or size to allow water from the pipe or toilet to move over the flexible head portion between the flexible head portion and the pipe or drain wall while the plunger is manipulated in the pipe or toilet. Using the handle portion, the flexible head portion can be moved along the inner wall of the pipe to move a column of liquid to effect the removal of the obstruction. If the intervals between the grooves are in contact with the pipe wall, water may still pass between the flexible head portion and the pipe through the grooves. A storage case for the device is provided.

Claims

1. A device for removing an obstruction from a pipe comprising:

a flexible head portion having a first end and a second end and operatively arranged for insertion into said pipe, said flexible head portion configured to allow said liquid to pass between the outer surface of said flexible head portion and the wall of said pipe for moving a column of liquid within said pipe;

a plurality of longitudinal grooves extending along the length of said flexible head portion; and

,

a handle portion attached to said second end.

2. The device as recited in claim 1 wherein said flexible head portion has a substantially rounded cross-sectional shape, wherein the diameter of said substantially rounded cross-sectional shape is smaller than the diameter of the cross-section of said pipe.

3. The device as recited in claim 1 wherein said flexible head portion is shaped to taper toward said first end.

4. The device as recited in claim 1 wherein said first end is flat.

5. The device as recited in claim 1 wherein said first end is concave.

6. The device as recited in claim 1 wherein said plurality of grooves extend from said first end to said second end.

7. The device as recited in claim 1 wherein said flexible head portion has a substantially multi-pointed cross-sectional shape.

8. The device as recited in claim 1 wherein said flexible head portion has a substantially clover-leaf cross-sectional shape.

9. The device as recited in claim 1 wherein said handle portion is detachably securable to said flexible head portion.

10. The device as recited in claim 1 wherein said flexible head portion comprises a smooth outer surface.

11. The device as recited in claim 10 wherein said smooth outer surface is hydrophobic.

12. The device as recited in claim 11 wherein said smooth outer surface is TEFLON®

.

13. The device as recited in claim 1 wherein said flexible head portion is capable of expansion and contraction.

14. The device as recited in claim 1 wherein said flexible head is formed from a material selected from the group consisting of rubber, foam, and plastic.

15. A method of removing an obstruction from a pipe comprising:

inserting a plunging device comprising a handle portion and a flexible head portion having a plurality of grooves into said pipe; and

,

moving said plunger-type device to cause movement of said flexible head portion within said pipe such that a column of liquid therein is moved between the outer surface of said flexible head portion and said pipe.

16. The method of removing an obstruction from a pipe as recited in claim 15 wherein said flexible head portion has a first end, wherein said first end is concave in shape.

17. The method of removing an obstruction from a pipe as recited in claim 15 wherein said flexible head portion is tapered.

18. An assembly comprising:

a device for removing an obstruction from a pipe, said device including;

a flexible head portion having a first end and a second end and operatively arranged for insertion into said pipe, said flexible head portion configured to allow said liquid to pass between the outer surface of said flexible head portion and the wall of said pipe for moving a column of liquid within said pipe;

a plurality of longitudinal grooves extending along the length of said flexible head portion; and

,

a handle portion attached to said second end; and

,

a storage case sized to receive and store said device.

19. The assembly as recited in claim 18 wherein said storage case is tubular in shape.

20. The assembly as recited in claim 18 wherein said storage case is rectangular in shape.
