Abstract

A film dispenser includes a holding member and a rotating member, the holding member including a first end including a handle, the handle including a plurality of lobes and a plurality of web portions, each web portion extending between a pair of adjacent lobes of the plurality of lobes; and a second end defining a brake portion defined by a slot, the holding member defining a longitudinal axis that extends from the first end to the second end, the slot including a first portion extending in a circumferential direction across a full width of the brake portion and two opposing portions extending at an angle from the first portion; each of the plurality of web portions extending outward beyond an outermost edge of the rotating member relative to the longitudinal axis.

First claim

That which is claimed is:

1. A film dispenser comprising:
a holding member comprising:
a first end comprising a handle, the handle comprising a plurality of lobes and a plurality of web portions, each web portion extending between a pair of adjacent lobes of the plurality of lobes; and
a second end defining a brake portion defined by a slot, the holding member defining a longitudinal axis that extends from the first end to the second end, the slot comprising a first portion extending in a circumferential direction across a full width of the brake portion and two opposing portions extending at an angle from the first portion; and

a rotating member, each of the plurality of web portions extending outward beyond an outermost edge of the rotating member relative to the longitudinal axis.

2. The film dispenser of claim 1 , wherein each of the plurality of lobes extends outward in a radial direction and is positioned between an outside extremity and an inside extremity of the holding member along a direction of the longitudinal axis.

3. The film dispenser of claim 2 , wherein each of the plurality of lobes extends outward beyond an outermost edge of the rotating member relative to the longitudinal axis.

4. The film dispenser of claim 2 , wherein the handle comprises four lobes.

5. The film dispenser of claim 1 , wherein the web portions together define a round shape.

6. The film dispenser of claim 5 , wherein the round shape defined by the web portions is concentric with the longitudinal axis.

7. The film dispenser of claim 1 , wherein a center of the brake portion is positioned circumferentially between a pair of adjacent lobes of the plurality of lobes relative to the longitudinal axis.

8. The film dispenser of claim 1 , further comprising a connecting portion extending radially inward from the brake portion, wherein the connecting portion is located toward an interior of the holding member along the longitudinal axis and away from an outside extremity of the first end of the holding member, the connecting portion extending in a plane that is angled with respect to the longitudinal axis of the holding member.

9. The film dispenser of claim 8 , wherein the holding member further comprises an interior holding surface comprising a concave surface facing the longitudinal axis of the holding member.

10. The film dispenser of claim 1 , wherein the holding member further comprises a plurality of stops extending from a one of the first end and the second end and configured to prevent movement of a one of a film roll and a rotating member of the film dispenser past an intersection of the first end and the second end of the holding member.

11. The film dispenser of claim 10 , wherein opposing stops of the plurality of stops define a stop diameter, the stop diameter being greater than a one of an inner diameter of the film roll and a diameter of a central hole of the rotating member.

12. A film dispenser comprising:
a holding member comprising:
a first end comprising a handle, the handle comprising a plurality of lobes and a plurality of web portions, each web portion extending between a pair of adjacent lobes of the plurality of lobes;
a second end defining a brake portion defining a slot, the holding member defining a longitudinal axis that extends from the first end to the second end; and
a connecting portion extending radially inward from the brake portion; and

a rotating member, each of the plurality of web portions extending outward beyond an outermost edge of the rotating member relative to the longitudinal axis.

13. The film dispenser of claim 12 , wherein each of the plurality of lobes extends outward in a radial direction relative to the longitudinal axis of the holding member, the plurality of lobes defining an exterior holding surface comprising a handle edge defined by an intersection between the exterior holding surface and an inside extremity of the holding member, a distance in a radial direction from the longitudinal axis of the holding member to the handle edge being greater at a radial centerline of each lobe than at a position between radial centerlines of adjacent lobes.

14. The film dispenser of claim 12 , wherein a center of the brake portion is positioned circumferentially between a pair of adjacent lobes of the plurality of lobes relative to the longitudinal axis.

15. The film dispenser of claim 12 , wherein a quantity of lobes is equal to a quantity of web portions.

16. The film dispenser of claim 12 , wherein the rotating member comprises an annular flange, the web portions together defining a circular edge that is concentric with the longitudinal axis, a diameter of the circular edge substantially equal to or greater than an outer diameter of the annular flange of the rotating member.

17. The film dispenser of claim 12 , further comprising a film roll, the film roll comprising a first end and a second end, the first end defining an opening, at least a portion of the holding member positioned inside the opening.

18. A method of dispensing material from a film roll, the method comprising:
holding onto an interior holding surface and an exterior holding surface of a first holding member with a first hand, the first holding member comprising:
a first end comprising the interior holding surface, a plurality of lobes and a plurality of web portions, each web portion extending between a pair of adjacent lobes of the plurality of lobes, the plurality of lobes and the plurality of web portions defining the exterior holding surface; and
a second end comprising a brake portion;
wherein the second end of the first holding member is inserted into a first rotating member inserted into an opening defined in the first end of the film roll, each of the plurality of web portions extending outward beyond an outermost edge of the first rotating member relative to a longitudinal axis of the first holding member;

holding onto an interior holding surface and an exterior holding surface of a second holding member with a second hand, the second holding member comprising:
a first end comprising the interior holding surface of the second holding member, a plurality of lobes and a plurality of web portions, each web portion of the second holding member extending between a pair of adjacent lobes of the plurality of lobes of the second holding member, the plurality of lobes of the second holding member and the plurality of web portions of the second holding member defining the exterior holding surface of the second holding member; and
a second end comprising a brake portion;
wherein the second end of the second holding member is inserted into a second rotating member inserted into an opening defined in the second end of the film roll, each of the plurality of web portions of the second holding member extending outward beyond an outermost edge of the second rotating member relative to a longitudinal axis of the second holding member;

dispensing the material by rotating the film roll relative to the first holding member and the second holding member; and
pressing onto the brake portion of one of the first holding member and the second holding member such that the brake portion brakes movement of the one of the first holding member and the second holding member into the corresponding rotating member to increase tension in or stretch the material being dispensed.

19. The method of claim 18 , wherein pressing onto the brake portion of the one of the first holding member and the second holding member comprises contacting the respective rotating
