Abstract
The specification discloses a loose-fill packing material comprising a plurality of individual packing elements, and a method of making such packing elements. Each packing element comprises at least two paper rings which are connected to each other at their outer surfaces. Each ring comprises a strip of paper which is rolled lengthwise upon itself. The rolls are fabricated by rolling sheets of paper to form elongated paper rolls having cylindrical outer surfaces and by then attaching pairs of elongated paper rolls together at their outer surfaces along their lengths. Individual packing elements are then cut from the pairs of elongated paper rolls.
Claims18
A loose-fill packing material of low bulk density in which the packing material comprises a plurality of individual packing elements, each individual packing element comprising:
- two paper rings;
- each ring formed of a separate strip of paper which is rolled lengthwise upon itself about a central axis forming multilayers with a cylindrical outer surface;
- and
- connecting means interconnecting the two rings along their outer surfaces.
A loose-fill packing material of low bulk density in which the packing material comprises a plurality of individual packing elements, each individual packing element comprising:
- two coreless paper rings;
- each ring including a separate strip of paper which is rolled lengthwise upon itself about a central axis forming a multilayer ring with cylindrical inner and outer surfaces;
- the coreless paper rings abutting each other along their outer surfaces;
- and
- adhesive along the outer surfaces securing the outer surfaces together to form the shape of a figure eight.
