Abstract

Claims (40)

1. A temporary door assembly kit, comprising:

a receptacle;

at least one zipper;

at least one partition strap, comprising:

a first hook portion configured to engage a sheet of material; and

a second hook portion connected to the first hook portion by an intermediate portion of the strap, the second hook portion configured to support a rolled up portion of a sheet of material,

wherein the first hook portion is constructed to pierce the sheet of material; and

a cutter configured to pierce and cut a sheet of material, comprising:

a handle;

at least one puncture finger extending from the handle, the at least one puncture finger having a piercing end configured pierce a sheet of material; and

at least one blade between the piercing end of at least one puncture finger and the handle, wherein the at least one puncture finger is oriented to define a cutting region between the at least one puncture finger and the handle, wherein the at least one blade is recessed in the cutting region and wherein the at least one puncture finger includes an angled guide surface that guides a sheet of material to be cut toward the cutting region.

2. The temporary door assembly kit of claim 1 , wherein the receptacle comprises a container for storing the at least one zipper and the cutter.

3. The temporary door assembly kit of claim 2 , wherein the receptacle comprises a resealable container.

4. The temporary door assembly kit of claim 2 , wherein the receptacle comprises one selected from the group consisting of a cardboard box, a paper box, a plastic container, a canvas bag, a plastic bag and a cloth bag.

5. The temporary door assembly kit of claim 2 , wherein the container is compartmentalized, such that each of the at least one zipper, the cutter, and the at least one partition strap can be separated within the container.

6. The temporary door assembly kit of claim 1 , wherein the at least one zipper and the cutter are enclosed within the receptacle.

7. The temporary door assembly kit of claim 6 , wherein the receptacle is compartmentalized, such that each of the at least one zipper and the cutter can be separated within the receptacle.

8. The temporary door assembly kit of claim 1 , wherein the at least one zipper comprises first and second flanges each having first and second teeth portions that can be meshed together or separated via a zipper pull.

9. The temporary door assembly kit of claim 8 , wherein a pre-applied adhesive material is disposed on each of the first and second flanges of the at least one zipper.

10. The temporary door assembly kit of claim 9 , wherein the at least one zipper further comprises a protective liner adhered to the pre-applied adhesive material disposed on each of the first and second flanges.

11. The temporary door assembly kit of claim 1 , wherein the at least one zipper comprises a first zipper and a second zipper, the first and second zippers each comprising first and second flanges each having first and second teeth portions that can be meshed together or separated via a zipper pull.

12. The temporary door assembly kit of claim 11 , wherein a pre-applied adhesive material is disposed on each of the first and second flanges of the first and second zippers.

13. The temporary door assembly kit of claim 1 , further comprising a sheet of material.

14. The temporary door assembly kit of claim 13 , wherein the sheet of material is provided within the receptacle.

15. The temporary door assembly kit of claim 1 , further comprising a roll of tape.

16. The temporary door assembly kit of claim 15 , wherein the roll of tape is provided within the receptacle.

17. The temporary door assembly kit of claim 1 ,

wherein the first hook portion lies on a first plane, and

wherein the first hook portion comprises a first portion and a second portion bent about a midpoint, and wherein the second portion of the first hook portion is positioned at an offset angle relative to the first plane.

18. The temporary door assembly kit of claim 17 , wherein the at least one partition strap comprises a first partition strap and a second partition strap.

19. The temporary door assembly kit of claim 18 , wherein the first and second partition straps are provided within the receptacle.

20. The temporary door assembly kit of claim 17 , wherein concave portions of the first and second hook portions face one another.

21. The temporary door assembly kit of claim 17 , wherein the second hook portion has a first radius of curvature, and the first hook portion has a second radius of curvature, wherein the first radius of curvature is greater than the second radius of curvature.

22. The temporary door assembly kit of claim 21 , wherein the second radius of curvature ranges between 1/16 of an inch and ⅝ of an inch.

23. The temporary door assembly kit of claim 21 , wherein the first radius of curvature ranges between 1½ inches and 3¼ inches.

24. The temporary door assembly kit of claim 17 , wherein a first end portion of the strap curves outward from the first hook portion.

25. The temporary door assembly kit of claim 24 , wherein the first end portion of the strap has a third radius of curvature greater than a first radius of curvature of the second hook portion and a second radius of curvature of the first hook portion.

26. The temporary door assembly kit of claim 25 , wherein the third radius of curvature ranges between 3½ inches and 6 inches.

27. The temporary door assembly kit of claim 17 , wherein the second portion of the first hook portion extends linearly at the offset angle relative to the first plane toward a first end of the second hook portion lying in the first plane on the same side of the intermediate portion.

28. The temporary door assembly kit of claim 1 , wherein the at least one puncture finger comprises a first puncture finger and a second puncture finger, and wherein first puncture finger and the second puncture finger comprise first and second blades between the piercing ends of the first and second puncture fingers and the handle that are constructed and arranged to cut two parallel incisions in the sheet of material.
