Abstract

A bundle of packing material includes at least two strips of packing material folded into a compact configuration. The strips of packing material include a top strip having a length dimension between first and second end portions and a central portion between the first end portion and the second end portion, and a bottom strip having a length dimension between first and second end portions and a central portion between the first end portion and the second end portion. The central portion of the top strip overlays the central portion of the bottom strip and the length dimension of the top strip is oriented orthogonal to the length dimension of the bottom strip. The first and second end portions of top strip are folded over the central portions, and the first and second end portions of the bottom strip are folded over the central portions.

First claim

1 . A bundle of packing material, comprising:
at least two strips of packing material folded into a compact bundle, including
a top strip of packing material having a length dimension with first and second end portions and a central portion between the first end portion and the second end portion, and
a bottom strip of packing material having a length dimension with first and second end portions and a central portion between the first end portion and the second end portion;
where the central portion of the top strip overlays the central portion of the bottom strip and the length dimension of the top strip is oriented orthogonal to the length dimension of the bottom strip, the first and second end portions of top strip are folded over the central portion of the top strip, and the first and second end portions of the bottom strip are folded over the central portion of the bottom strip.

2 . A bundle as set forth in claim 1 , where the central portion of the top strip has a top side and a bottom side opposite the top side, and the first and second end portions of the top strip are folded over the top side of the top strip, and the first and second end portions of the bottom strip are folded over a top side of the central portion of the top strip.

3 . A bundle as set forth in claim 1 , where one of the first end portion and the second end portion of the top strip are folded over one of the first end portion and the second end portion of the bottom strip.

4 . A bundle as set forth in claim 1 , where the first end portions and the second end portions of the top strip and the bottom strip are interleaved.

5 . A bundle as set forth in claim 1 , further comprising a restraining member to temporarily secure the strips of packing material in the bundled configuration.

6 . A bundle as set forth in claim 5 , where the restraining member is a strap.

7 . A bundle as set forth in claim 1 , where the strips of packing material are made at least partially of paper.

8 . A bundle as set forth in claim 1 , where the strips of packing material include randomly-crumpled paper.

9 . A bundle as set forth in claim 1 , where the strips of packing material are selected based on one or more of the following factors: (a) a width dimension of the strip of packing material relative to a width of a respective side wall of a container; (b) insulating properties of the strip of packing material; and (c) cushioning properties of the packing material.

10 . A method of making a bundle of packing material from two strips of packing material, comprising the steps of:
providing two strips of packing material, including
a top strip of packing material having a length dimension with first and second end portions and a central portion between the first end portion and the second end portion, and
a bottom strip of packing material having a length dimension with first and second end portions and a central portion between the first end portion and the second end portion;
placing the central portion of the top strip over the central portion of the bottom strip such that the length dimension of the top strip is orthogonal to the length dimension of the bottom strip; folding the first end portion and the second end portion of top strip over the central portion of the top strip; and folding the first end portion and the second end portion of the bottom strip over the central portion of the bottom strip.

11 . A method as set forth in claim 10 , after the folding steps, further comprising the step of applying a restraining member to temporarily secure the strips of packing material in a bundled configuration.

12 . A method as set forth in claim 10 , where the folding steps include interleaving the first end portions and the second end portions of the top strip and the bottom strip.

13 . A method as set forth in claim 10 , where the providing step includes selecting strips of packing material made at least partially of paper.

14 . A method as set forth in claim 10 , where the providing step includes selecting strips of packing material that include randomly-crumpled paper.

15 . A method as set forth in claim 10 , where the providing step includes selecting strips of packing material based on one or more of the following factors: (a) a width dimension of the strip of packing material relative to a width of a respective side wall of a container; (b) insulating properties of the strip of packing material; and (c) cushioning properties of the packing material.

16 . A method of using a bundle of packing material as set forth in claim 1 , comprising the following steps:
providing a rectangular packing container with an open top side and a closed bottom side opposite the top side; placing the bundle of packing material in the packing container with a bottom side of the central section of the bottom strip against an inner surface of the bottom side of the packing container; unfolding the first end portions and the second end portions of the top strip and the bottom strip against respective side walls of the packing container.

17 . A method as set forth in claim 16 , further comprising the step of releasing the bundle from a temporary restraining member.

18 . A method as set forth in claim 16 , further comprising the step of placing an article to be packed on a top side of the central section of the top strip, and folding respective first end portions and second end portions of the top strip and the bottom strip over the article, and closing the open top side of the packing container.

19 . An insulating strip of dunnage, comprising:
one or more crumpled interior sheets; and one or more cover sheets wrapped around the interior sheets and sealed at the edges.

20 . An insulating strip as set forth in claim 19 , where at least one of the interior sheets is randomly crumpled, and the cover sheet extends beyond the crumpled interior sheets in all directions.
