I claim:

1. An adapter tool for paper rolls that do not have inner cardboard tubes, comprising:

a hollow cylinder having a first end and a second end opposite the first end with a generally uniform diameter opening therebetween; and

a spiral on the exterior surface of the hollow cylinder between the first end and the second end, wherein the first end is adapted to be pushed into a central opening of a paper roll that does not have an inner cardboard tube, and the insert is able to be rotated by the second end until substantially all of the insert is located inside the central opening of the paper roll.

2. The adapter tool of claim 1, wherein the hollow

cylinder has a length of at least approximately 4 inches between the first end and the second end, and the paper roll is a toilet paper roll without an inner cardboard tube.

3. The adapter tool of claim 1, wherein the first end has a chamfered edge, and the second end has an enlarged base having an outer diameter greater than the outer diameter of the hollow cylinder.

4. The adapter tool of claim 3, wherein the chamfered edge has an angle of approximately 30 degrees.

5. The adapter tool of claim 1, wherein the spiral

includes: a spiral cut groove.

6. The adapter tool of claim 5, wherein the spiral cut groove includes: a cut approximately .063 inches deep.

7. The adapter tool of claim 6, wherein the spiral cut groove includes: a width of approximately 0.125 inches.

8. The adapter tool of claim 5, wherein the spiral

includes: an approximately 1 inch spiral pitch.

9. The adapter tool of claim 1, wherein the spiral

includes: a spiral raised rib.

10. The adapter tool of claim 9, wherein the spiral raised rib includes: a height of approximately 0.3 inches.

11. The adapter tool of claim 9, wherein the spiral raised rib includes: a thickness of approximately 0.125 inches.

12. The adapter tool of claim 1, wherein the hollow

cylinder has a length of at least approximately 6 inches between the first end and the second end, and the paper roll is a paper towel roll without an inner cardboard tube.

13. The adapter tool of claim 12, wherein the spiral includes: a spiral cut groove approximately .063 inches deep.

14. The adapter tool of claim 13 , wherein the spiral cut groove includes: a width of approximately 0.125 inches.

15. The adapter tool of claim 13, wherein the spiral cut groove includes: an approximately 1 inch spiral pitch.

16. The adapter tool of claim 12, wherein the spiral includes: a spiral raised rib.

17. The adapter tool of claim 16, wherein the spiral raised rib includes: a height of approximately 0.3 inches.

18. The adapter tool of claim 16, wherein the spiral raised rib includes: a thickness of approximately 0.125 inches.

19. A method of mounting paper rolls that do not have inner cardboard tubes, on paper dispensers, comprising the steps of:

providing a paper roll with a central opening that does not have an inner cardboard tube, the roll being selected from a toilet paper roll and a paper towel roll;

providing a rigid hollow cylinder having a tip end with a chamfered edge and an opposite end with an enlarged base; providing a spiral on an exterior surface of the cylinder between the tip end and the base;

pushing and rotating the tip end of the base into the central opening of the paper roll with the enlarged base until the cylinder is substantially inside the central opening of the paper roll, and the enlarged base abuts against a side surface of the paper roll.

20. The method of claim 19, further comprising the steps of:

providing the spiral as a spiral groove or spiral raised rib; and

providing the spiral with an approximately 1.00 inch spiral pitch.

21. The adapter tool of claim 3, wherein the cylinder is formed from plastic.

22. The adapter tool of claim 3, wherein the cylinder is formed from wood.

23. The adapter tool of claim 3, wherein the cylinder is formed from metal.

24. The adapter tool of claim 3, wherein the hollow cylinder includes an outer diameter of approximately 1.250 inches.

25. The adapter tool of claim 24, wherein the generally uniform diameter opening through the hollow cylinder has an inner diameter of approximately 1.00 inches.

26. The adapter tool of claim 2, wherein the hollow tube includes 4 winds of spiral, each wind approximately one inch apart from one another.

27. The adapter tool of claim 12, wherein the hollow tube includes 6 winds of spiral, each wind approximately one inch apart from one another.

28. The method of claim 20, further comprising the steps of:

providing a toilet paper roll and the paper roll; and providing the cylinder with approximately 4 winds of the spiral.

29. The method of claim 28, wherein the rotating step includes the step of:

rotating the cylinder approximately 4 turns to be fully inserted into the toilet paper roll.

30. The method of claim 20, further comprising the steps of:

providing a paper towel roll as the paper roll; and providing the cylinder with approximately 6 winds of the spiral.

31. The method of claim 30, wherein rotating step includes the step of:

rotating the cylinder approximately 6 turns to be fully inserted into the paper towel roll.
