Abstract

A film dispenser includes a holding member including a first end and a second end joined to the first end, the holding member defining a longitudinal axis extending from the first end to the second end, the second end defining a brake portion and a slot defined by the brake portion, the slot including a first slot portion extending in a circumferential direction across a width of the brake portion and second and third slot portions extending across a length of the brake portion, the second and third slot portions distal from each other on opposing sides of the brake portion, the slot further including fourth and fifth slot portions angled with respect to the second and third slot portions, respectively, the fourth and fifth slot portions extending in a circumferential direction, the fourth and fifth slot portions of the slot intersecting the second and third slot portions, respectively.

First claim

That which is claimed is:

1. A film dispenser comprising a holding member, the holding member comprising:
a first end; and
a second end joined to the first end, the holding member defining a longitudinal axis extending from the first end to the second end, the second end defining:
a brake portion; and
a slot defined by the brake portion, the slot comprising a first slot portion extending in a circumferential direction across a width of the brake portion and a second slot portion and a third slot portion extending across a length of the brake portion, the second slot portion and the third slot portion distal from each other on opposing sides of the brake portion, the slot further comprising a fourth slot portion angled with respect to the second slot portion and a fifth slot portion angled with respect to the third slot portion, the fourth slot portion and the fifth slot portion extending in a circumferential direction, the fourth slot portion of the slot intersecting the second slot portion of the slot and the fifth slot portion of the slot intersecting the third slot portion of the slot.

2. The film dispenser of claim 1 , wherein the first end of the holding member comprises an exterior holding surface having a constant radius of curvature about the full circumference of the holding member.

3. The film dispenser of claim 1 , wherein the first end of the holding member comprises a handle and defines an interior holding surface and wherein the interior holding surface is curved and has a radius of curvature that is not concentric with the longitudinal axis.

4. The film dispenser of claim 1 , wherein the first end of the holding member comprises a blend extending along the circumference of a central hole of the holding member.

5. The film dispenser of claim 1 , wherein the first end of the holding member defines a chamfered region extending from an edge of a central hole of the holding member.

6. The film dispenser of claim 1 , wherein each of the fourth slot portion and the fifth slot portion of the slot is straight.

7. The film dispenser of claim 1 , wherein the fourth slot portion is angled at 90 degrees with respect to the second slot portion and the fifth slot portion is angled at 90 degrees with respect to the third slot portion.

8. The film dispenser of claim 1 , wherein the fourth slot portion of the slot begins at an end point of the second slot portion of the slot and the fifth slot portion of the slot begins at an end point of the third slot portion of the slot.

9. The film dispenser of claim 1 , further comprising a rotating member comprising a first end and a second end, the rotating member defining an axis of rotation that extends from the first end to the second end, the longitudinal axis of the holding member aligned with the axis of rotation of the rotating member; wherein the first end of the holding member comprises an inside extremity and a distance from the inside extremity of the first end of the holding member to the snap measured in direction that is parallel to the longitudinal axis of the holding member is greater than an overall length of the rotating member measured in direction that is parallel to the axis of rotation of the rotating member, the rotating member able to fit between the snap and the inside extremity of the first end of the holding member.

10. The film dispenser of claim 1 , further comprising a rotating member comprising a first end and a second end, the rotating member defining an axis of rotation that extends from the first end to the second end, the longitudinal axis of the holding member aligned with the axis of rotation of the rotating member.

11. The film dispenser of claim 10 , wherein the rotating member further comprises a plurality of ribs on an exterior surface, each of the plurality of ribs defining a semi-circular shape in a cross-section taken along a radial direction of the rotating member.

12. The film dispenser of claim 11 , wherein the snap has a ramp surface angled from the longitudinal axis and configured to provide a camming motion to the snap as the holding member is inserted into the rotating member.

13. The film dispenser of claim 1 , wherein the holding member further comprises a snap proximate to an outside extremity of the second end of the holding member, the defining a slot.

14. The film dispenser of claim 1 , wherein the holding member further comprises a connecting portion extending radially inward from the brake portion towards the longitudinal axis.

15. The film dispenser of claim 1 , a rotating member having a first end and a second end, the rotating member defining an axis of rotation that extends from the first end to the second end, the longitudinal axis of the holding member aligned with the axis of rotation of the rotating member.

16. A method of braking a film dispenser, the method comprising:
holding the film dispenser by gripping a holding member of the film dispenser, the holding member comprising a first end, a second end, and a brake portion, the holding member defining a longitudinal axis that extends from the first end to the second of the holding member;
dispensing film from a film roll of the film dispenser by rotating the film roll about the second end of the holding member; and
braking the film dispenser by pressing the brake portion of the holding member to at least indirectly engage the brake portion with the film roll to increase a tension in the film being dispensed, the brake portion comprising a width and a length, the brake portion defined in the second end of the holding member by a slot, the slot comprising a first slot portion extending in a circumferential direction across the width of the brake portion and a second slot portion and a third slot portion extending across the length of the brake portion, the first slot portion and the second slot portion of the slot distal from each other on opposing sides of the brake portion, the slot further comprising a fourth slot portion and a fifth slot portion extending in a circumferential direction, the fourth slot portion of the slot intersecting the second slot portion of the slot and the fifth slot portion of the slot intersecting the third slot portion of the slot.

17. The method of claim 16 , wherein an edge of each of the fourth slot portion and the fifth slot portion of the slot is straight.

18. The method of claim 17 , wherein the first end of the holding member defines a chamfered region extending from an edge of a central hole of the holding member, the method further comprising contacting the chamfered region with a hand of the user.

19. The method of claim 16 , wherein the film dispenser further comprises a rotating member comprising a first end and a second end, the rotating member defining an axis of rotation that extends from the first end to the second end, the longitudinal axis of the holding member aligned with the axis of rotation of the rotating member.

20. The method of claim 19 , further comprising positioning the rotating member between a snap and the first end of the holding member.

21. A method of assembling a film dispenser, the method comprising:
inserting a first holding member of the film dispenser into a film roll of the film dispenser by pushing the first holding member into a first end of the film roll, the first holding member comprising a first brake portion comprising a width and a length, the first brake portion defined in the first holding member by a first slot, the first slot comprising a first slot portion extending in a cir
