Abstract

A dispenser includes a rotating member including a first end and a second end, the rotating member having an inner surface and defining an axis of rotation that extends from the first end to the second end; a holding member having an inner surface, an outer holding surface, and a collar at a first end of the holding member, the inner surface enclosing an engaging portion of the rotating member; and a cap attached to the first end of the rotating member and holding the holding member, the collar of the holding member positioned at least partially directly between an end surface at the first end of the rotating member and a stop surface of the cap.

First claim

That which is claimed is:

1. A dispenser comprising:
a rotating member including a first end and a second end, the rotating member having an inner surface and defining an axis of rotation that extends from the first end to the second end;
a holding member having an inner surface, an outer holding surface, and a collar at a first end of the holding member, the inner surface enclosing an engaging portion of the rotating member; and
a cap attached to the first end of the rotating member and holding the holding member, the collar of the holding member positioned at least partially directly between an end surface at the first end of the rotating member and a stop surface of the cap, the cap configured to rotate relative to the holding member.

2. The dispenser of claim 1 , wherein the cap includes an outer circumferential wall and an inner circumferential wall, the cap enclosing a portion of the holding member between the outer circumferential wall and the inner circumferential wall.

3. The dispenser of claim 2 , wherein the cap includes a shoulder between the stop surface and an outer surface of the inner circumferential wall.

4. The dispenser of claim 1 , further comprising wrap rolled around the rotating member, the cap and the wrap capturing the holding member on the rotating member.

5. The dispenser of claim 1 , wherein
the collar defines an inner surface and wherein the inner surface of the collar is slidable against the end surface of the rotating member as the rotating member rotates relative to the holding member, and
the collar defines an outer surface and the outer surface of the collar is slidable against the end surface of the cap as the cap rotates with the rotating member relative to the holding member.

6. The dispenser of claim 1 , wherein:
the rotating member has a cylindrical shape;
the holding member has a cylindrical shape; and
the collar defines a continuous unbroken circle.

7. The dispenser of claim 1 , wherein:
the inner surface of the holding member defines a first diameter;
the collar defines an opening having a second diameter; and
an outer surface of the rotating member defines a third diameter, wherein the third diameter of the rotating member is greater than the second diameter of the collar and less than the first diameter of the holding member.

8. The dispenser of claim 1 , wherein the collar extends radially inward from the inner surface of the holding member.

9. The dispenser of claim 1 , wherein the first end of the rotating member is axially between an end surface at an inner end of the cap and the stop surface of the cap.

10. The dispenser of claim 1 , wherein:
the holding member includes a flange at a second end of the holding member; and
a flange surface of the flange abuts wrap rolled around the rotating member.

11. The dispenser of claim 1 , wherein the cap is rotationally fixed relative to the rotating member.

12. A method of assembling a wrap dispenser comprising:
enclosing an engaging portion of a rotating member with a holding member; and
attaching a cap proximate to a first end of the rotating member by contacting an insertion portion of the cap to an inner surface of the rotating member with a collar of the holding member positioned at least partially directly between an end surface at the first end of the rotating member and a stop surface of the cap, the cap configured to rotate relative to the holding member.

13. The method of claim 12 , wherein attaching the cap includes enclosing a portion of the holding member between an outer circumferential wall and an inner circumferential wall, the cap preventing removal of the holding member from the rotating member over the first end of the rotating member.

14. The method of claim 12 , wherein attaching the cap includes capturing the holding member to the engaging portion of the rotating member between the cap and a roll of wrap positioned on a roll-holding portion of the rotating member.

15. The method of claim 12 , wherein the collar defines an inner surface and wherein the inner surface of the collar is slidable against the end surface of the rotating member as the rotating member rotates relative to the holding member.

16. The method of claim 12 , wherein:
the holding member includes the collar at a first end of the holding member;
the holding member includes a flange at a second end of the holding member; and
enclosing an engaging portion of the rotating member includes positioning a flange surface of the flange adjacent to a roll of wrap positioned on a roll-holding portion of the rotating member.

17. The method of claim 12 , wherein the cap is rotationally fixed relative to the rotating member.

18. A method of dispensing wrap from a roll using a dispenser, the method comprising:
gripping onto an outer holding surface of a holding member of the dispenser, the holding member enclosing an engaging portion of a rotating member of the dispenser, the dispenser further including:
wrap wrapped around a roll-holding portion of the rotating member, and
a cap attached to the first end of the rotating member and holding the holding member with a collar of the holding member positioned at least partially directly between an end surface at the first end of the rotating member and a stop surface of the cap, the cap configured to rotate relative to the holding member; and

dispensing the wrap by rotating the rotating member relative to the holding member.

19. The method of claim 18 , wherein the cap includes an outer circumferential wall and an inner circumferential wall, the cap enclosing a portion of the holding member between the outer circumferential wall and the inner circumferential wall.

20. The method of claim 18 , further comprising applying pressure onto the holding member to increase the tension in the wrap being dispensed.

21. The method of claim 20 , wherein applying pressure onto the holding member includes compressing the holding member to engage the rotating member, and wherein compressing the holding member includes increasing the resistance to rotation of the rotating member and tension in the wrap by increasing the friction between the rotating member and the holding member.

22. The method of claim 18 , further comprising slidably positioning the holding member on the rotating member to engage an inner surface of the collar with the end surface of the rotating member, wherein engaging the inner surface of the collar with the end surface of the rotating member increases the resistance to rotation of the rotating member and tension in the wrap by increasing the friction between the rotating member and the holding member.

23. The method of claim 18 , wherein the cap is rotationally fixed relative to the rotating member.
