Hand dispenser for stretch wrap

Abstract

A hand dispenser for stretch film. The stretch film from the hand dispenser is dispensed by using one hand from a person. The hand dispenser comprises a handle with prongs, a collar with a flange and a notched cylinder with flexible sections, and a foam sleeve for a cushion grip. The handle prongs are inserted into the extended core of the roll. The film is wound around one end of the extended core.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a one handed dispenser showing a handle 12. The handle 12 in a preferred embodiment being molded. The handle 12 having a top flange 14 and a bottom flange 16. An additional flange 18 at the opposite end of the handle 12 is used to lock the film core in place once it has been inserted onto the prongs 50 and 52. The dispenser 10 has a molded collar 40 consisting of a notched cylinder 30 with a flange 42. The dispenser 10 has a foam sleeve 20 for a cushion grip which fits over the handle 12 and extends beyond the top flange 14 of the handle 12. The molded collar 40 fits over the extended core 60 so that the notched cylinder 30 is recessed beneath the foam sleeve 20 and rests against the top flange 14 of the handle 12. The sleeve 20 fits snugly over the notched cylinder 30. The snug fit compresses the notched cylinder 30 enough to act as a slight brake against the extended core 60 without additional pressure. If desired, additional pressure applied to the handle at this point forces the notched cylinder 30 to compress against the extended core 60 of the roll of film resting against the top flange 14 of the handle 12 thereby acting as a further brake by increasing the friction between the notched cylinder 30 and the extended core 60. This will increase the tension of the film as it unwinds. Handle prongs 50 and 52 are inserted into the extended core 60. A film (not shown in FIG. 1) is wound around one end of the extended core 60. The collar 40 has a flange 42 to keep the hand off the edge of the roll as it unwinds.

FIG. 2 shows the collar 40 having a notched cylinder 30 and a flange 42.

FIG. 3 shows the handle 12 which has the handle prongs 50 and 52. The notched cylinder portion 30 of the collar 40 is inserted into the foam sleeve 20 with the flange 42 showing above the top of the foam sleeve 20.

FIG. 4 shows a roll of film 100 wound onto one end of an extended core 60.

FIG. 5 shows the roll of film 100 attached to the handle 12 with the collar 40 in place and the flange 42 separating the foam sleeve 20 on the handle from the roll of film 100.

Claims

2. The hand dispenser of claim 1 wherein said stretch film is dispensed by using one hand

3. The hand dispenser of claim 1 wherein said handle prongs are inserted into an extended core of a roll.

4. The hand dispenser of claim 1 wherein film is wound around an extended core.

5. The hand dispenser of claim 1 wherein said collar comprises a flange which keeps a person's hand off a roll of film as it unwinds.

6. The hand dispenser of claim 1 wherein said collar comprises a notched cylinder with flexible sections attached to said flange.

7. The hand dispenser of claim 6 wherein said notched cylinder has flexible sections which fit over an extended core of a roll.

8. The hand dispenser of claim 7 wherein said flexible sections of said notched cylinder are used as a brake if needed by applying slight pressure on said sleeve which fits over said flexible sections of said notched cylinder.

9. The hand dispenser of claim 7 wherein said sleeve is a foam sleeve for a cushion grip which fits over said handle as well as said flexible sections of said notched cylinder which is part of said collar.

10. The hand dispenser of claim 1 wherein said sleeve fits snuggly over a notched cylinder, and said snug fit compresses said notched cylinder enough to act as a brake against the extended core without additional pressure.

11. The hand dispenser of claim 1 wherein a roll of stretch wrap film is slid over said prongs at front of said dispenser and a roll of film is snapped in place.

12. The hand dispenser of claim 1 wherein no additional tension is needed to activate a films holding power.

13. The hand dispenser of claim 1 wherein said dispenser works on narrow films, of no more than five inches.

14. The hand dispenser of claim 1 wherein said collar has a notched cylindrical portion with flexible sections.

15. The hand dispenser of claim 1 wherein with adjustable pressure from the fore finger through the foam sleeve and collar at top portion of said handle closest to where roll of film is wound provides additional breaking action.

16. The hand dispenser of claim 1 wherein said handle is reusable.

17. The hand dispenser of claim 1 wherein said handle is easily removed from said dispenser by squeezing together said two prongs at one end of said handle and pulling said handle out of said core.

18. The hand dispenser of claim 1 wherein said dispenser has a manually operable braking system that is adjustable to permit application of braking tension over a wide range.

19. The hand dispenser of claim 1 wherein tension in film is controllable during a wrapping process.

20. The hand dispenser of claim 1 wherein said dispenser provides good balance and facilitates application of film under substantially uniform tension across the full width of said film for a uniform wrap.
