Abstract

A dispenser comprising a rotating member and a holding member. The rotating member includes a first portion and a second portion. The first portion has an outer surface and a cylindrical inner surface defining a diameter. The second portion has an outer surface and a cylindrical inner surface defining a diameter. The diameter of the cylindrical inner surface of the second portion is greater than the diameter of the cylindrical inner surface of the first portion. A plurality of ribs extends radially inwardly from the cylindrical inner surface of the second portion. The holding member is located radially outwardly of the first portion. The holding member has an inner surface and an outer surface.

First claim

That which is claimed is:

1. A dispenser comprising:
a rotating member including a first portion and a second portion, the first portion having an outer surface and a cylindrical inner surface defining a diameter, the second portion having an outer surface and a cylindrical inner surface defining a diameter, wherein the diameter of the cylindrical inner surface of the second portion is greater than the diameter of the cylindrical inner surface of the first portion, a plurality of ribs extending radially inwardly from the cylindrical inner surface of the second portion, each of the ribs defining a free radially inward edge; and
a holding member located radially outwardly of the first portion, the holding member having an inner surface and an outer surface.

2. The dispenser of claim 1 , wherein the free radially inward edges define a diameter equal to the diameter of the cylindrical inner surface of the first portion.

3. The dispenser of claim 1 , wherein the holding member is configured to allow the holding member to rotate relative to the rotating member and to allow the holding member to frictionally engage the rotating member upon radially inward force applied to the holding member.

4. The dispenser of claim 1 , wherein the outer surface of the holding member includes a plurality of indentions.

5. The dispenser of claim 1 , wherein the rotating member has an upset protruding radially outwardly from the outer surface of the first portion, the holding member located longitudinally between the upset and the second portion.

6. The dispenser of claim 5 , wherein the upset includes a chamfered surface and an annular flat surface.

7. The dispenser of claim 5 , wherein the upset defines a diameter greater than a diameter defined by the inner surface of the holding member.

8. The dispenser of claim 7 , wherein the upset is circumferentially continuous.

9. The dispenser of claim 7 , wherein the first portion of the rotating member defines a slot extending longitudinally through the upset.

10. The dispenser of claim 1 , wherein the holding member includes a radially outwardly extending flange at an end.

11. The dispenser of claim 1 , wherein the rotating member includes a third portion located laterally between the first portion and the second portion, the third portion having a conical outer surface, and wherein each rib extends to an inner surface of the third portion.

12. The dispenser of claim 1 , wherein the rotating member has a first end defined at the first portion and a second end defined at the second portion, and each rib has a terminal edge located a distance from the second end.

13. A dispenser comprising:
a rotating member including a first portion having an outer surface and a cylindrical inner surface defining a diameter, a second portion having an outer surface and a cylindrical inner surface defining a diameter, the diameter of the cylindrical inner surface of the second portion is greater than the diameter of the cylindrical inner surface of the first portion, a third portion having a conical outer surface and an inner surface, a plurality of ribs extends radially inwardly from inner surfaces of the second and third portions; and
a roll of wrap located radially outwardly of the outer surface of the second portion.

14. The dispenser of claim 13 , wherein the plurality of ribs has radially inward edges defining a diameter equal to the diameter of cylindrical inner surface of the first portion.

15. The dispenser of claim 14 further comprises a holding member located radially outwardly of the first portion.

16. The dispenser of claim 15 , wherein the rotating member has an upset extending radially outward from the outer surface of the first portion, the holding member located longitudinally between the upset and the second portion.

17. A method of assembling a wrap dispenser comprising the steps of:
providing a rotating member including a first portion and a second portion, the first portion having an outer surface and a cylindrical inner surface defining a diameter, the second portion having an outer surface and a cylindrical inner surface defining a diameter, wherein the diameter of the cylindrical inner surface of the second portion is greater than the diameter of the cylindrical inner surface of the first portion, a plurality of ribs extending radially inwardly from the cylindrical inner surface of the second portion, each of the ribs defining a free radially inward edge;
providing a holding member having an inner surface, an outer surface, and an opening; and
inserting the first portion of the rotating member through the opening of the holding member.

18. The method of claim 17 , wherein the first portion of the rotating member has an upset extending radially outwardly from the outer surface of the first portion and the upset has a diameter greater than the diameter of the inner surface of the holding member, and wherein the step of inserting the first portion of the rotating member through the opening of the holding member includes sliding the holding member over the upset.

19. The method of claim 18 , wherein the upset is circumferentially continuous, and wherein the step of sliding the holding member over the upset includes stretching the holding member radially outwardly as the holding member slides over the upset.

20. The method of claim 18 , wherein the first portion of the rotating member defines a slot extending axially through the upset, and wherein the step of sliding the holding member over the upset includes compressing the upset radially inwardly as the holding member slides over the upset.
