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, the holding member configured to rotate relative to the rotating member, and a cap attached to the first end of the rotating member and retaining the holding member on the rotating 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, an end gap between the end surface and the stop surface providing clearance for the collar.

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, the holding member configured to rotate relative to the rotating member; and
a cap attached to the first end of the rotating member and retaining the holding member on the rotating 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 within an end gap defined between the end surface and the stop surface providing clearance for the collar.

2. The dispenser of claim 1 , wherein the cap defines a rim portion, a shoulder portion, and an insertion portion, the shoulder portion positioned between the rim portion and the insertion portion.

3. The dispenser of claim 2 , wherein the insertion portion of the cap is positioned within the rotating member and frictionally engages the inner surface of the rotating member, the cap rotationally fixed to the rotating member.

4. The dispenser of claim 3 , wherein the shoulder portion is configured to limit how far the insertion portion is inserted into the rotating member.

5. The dispenser of claim 2 , wherein the stop surface is defined by the rim portion of the cap, the shoulder portion sized to maintain the end gap between the stop surface and the end surface of the rotating member.

6. The dispenser of claim 2 , wherein the rim portion has an outer rim diameter, the shoulder portion has an outer shoulder diameter, and the insertion portion has an outer insertion portion diameter, the outer shoulder diameter sized to be larger than the outer insertion portion diameter but smaller than the outer rim diameter.

7. The dispenser of claim 1 , wherein the rotating member comprises a roll of wrap disposed on the rotating member between the second end of the rotating member and the engaging portion of the rotating member, and interference between the collar and the first end of the rotating member prevents contact between the holding member and the roll of wrap.

8. The dispenser of claim 1 , wherein the inner surface of the holding member defines a protuberance extending radially inwardly from the inner surface towards the engaging portion of the rotating member.

9. The dispenser of claim 8 , wherein the protuberance is a circumferential rib.

10. The dispenser of claim 8 , wherein the protuberance is defined proximate the collar.

11. The dispenser of claim 1 , wherein the cap comprises an inner circumferential wall positioned within the first end of the rotating member, the inner circumferential wall having an outer surface defining a vertical rib extending radially outwardly from the outer surface.

12. A method of assembling a wrap dispenser comprising:
sliding a holding member onto the engaging portion of a rotating member; and
inserting an insertion portion of a cap through a collar of the holding member and into a first end of the rotating member, the insertion portion frictionally engaging an inner surface of the rotating member, at least a portion of the collar retained between an end surface at the first end of the rotating member and a stop surface of a rim of the cap.

13. The method of claim 12 , wherein the insertion portion comprises an inner circumferential wall defining an outer surface, the outer surface defining a vertical rib extending outwardly from the outer surface, the vertical rib resisting withdrawal of the insertion portion from the first end of the rotating member after inserting the insertion portion into the first end of the rotating member.

14. The method of claim 12 , wherein the insertion portion of the cap is inserted into the rotating member until a shoulder portion of the cap rests against the end surface of the first end of the rotating member.

15. The method of claim 12 , wherein the holding member has a protuberance defined by an inner surface of the holding member, the protuberance configured to align the holding member on the engaging portion of the rotating member.

16. The method of claim 15 , wherein the protuberance is a circumferential rib extending radially inwardly from the inner surface of the holding member.

17. 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, interference between the collar and the first end of the rotating member preventing contact between the roll of wrap and the second end of the holding 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, an end gap between the end surface and the stop surface providing clearance for the collar; and

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

19. The method of claim 18 , wherein the cap has a shoulder portion which maintains the end gap.

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.
