Abstract

(57) [Summary] (Modified) [Purpose] A packaging method in which impact-resistant cellulose wadding is used in place of conventional packaging materials and at the same time environmental problems are not caused when the packaging materials are discarded. A pressure-sensitive copying paper reel 1 is wrapped in a circumferential or spiral shape by a wrapping material 2, and the wrapping material 2 extends in a radial direction so as to extend beyond an end edge portion 3 and partially cover an end surface 5 of the reel. As indicated by the inner reference numeral 4, it is bent with respect to the end surface 5 of the reel.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved packaging method for protecting a paper reel, and more specifically, a cylindrical material such as pressure-sensitive copying paper.

[0002]

European Patent Application No. 88310778.2 (Publication No. 0276174) discloses a process and apparatus for protective packaging of pressure sensitive paper rolls and rolls of such material to be packaged. In particular, it is proposed that such a reel be laminated with a foamable packaging material and a synthetic plastic film material in a sheet form and wound on a reel. The foamable packaging material is polyolefin foamable packaging material and the synthetic plastic film is polyethylene. Alternatively, it is preferable to use a stretched film of polyvinyl chloride. Although the packaging method described in the above patent application is effective for proper protection of the pressure-sensitive paper reel, the polyolefin foam sheet or polyurethane foam sheet currently used for such packaging is removed by the user from the reel. When disposing
It is known to cause environmental problems.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging method capable of protecting the above-mentioned problems from a carbonless paper reel or another cylindrical object by using a cushioning material.

[0004]

SUMMARY OF THE INVENTION To achieve the above objectives, there is provided a method of packaging cylinders for impact resistance with cellulosic cots. The cylinder consists of a pressure sensitive material reel, such as carbonless copy paper, and the batting is usually wrapped around the cylinder or reel in a circumferential or spiral fashion.

The padding is optional, but a paper sheet made of stretchable paper such as crepe paper is applied to one side or both sides. The present packaging may use a film such as a stretched film. The film is then overlaid or inserted between the cellulose swatches.

The wadding and film cover the end surface beyond each edge of the reel so that it can cover a portion of the end surface of the reel, thereby protecting the edge.

Paper slugs are made up of, for example, 8 layers of 22.5 gm ² unbleached recycled tissue paper laminated with 40 gm ² paper sheets and starch size adhesive and have a width of 330 mm. A suitable padding is Papierfabrik Hed, D-5419, Germany.
Available from wigsthal. The other cotton wrap mentioned above
Using 45 gm ² paper sheets, such as pseudo-embossed sulfuric acid paper, and 25 gm ² unbleached tissue paper, which is laminated in four layers by embossing with a circular pattern of about 8 mm hatch pattern with 5 cm intervals in length and width. I do not care. This wadding is British CW7 3QJ
Jiffy in Industrial Estate, Winsford, Cheshire
Available from Packaging.

A suitable stretched film is a 460 mm wide 30 micron unpigmented polyethylene film, which is British BS17.
DRGP located in 3LN Carsons Road, Mengotsfield, Bristol
Available from lastic Films. The present invention includes a cylinder, such as a pressure sensitive copy paper reel, which is packaged for impact resistance, the wrapping material comprising a cellulose wrap wrapped around the cylinder.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1 by reference numeral (13), a pressure-sensitive copying paper reel (1) is wrapped with a packaging material (2) in a circumferential direction or in a spiral shape, and the packaging material is Radially inward so as to partially cover the reel end surface (5) beyond the edge (3)
As shown in (4), it is bent with respect to the end surface (5) of the reel.

FIG. 2 shows a paper roll (1) according to the invention.
The first packaging mode is shown in which the cellulose bottling (6) and the stretched film (7) are alternately laminated and packaged. FIG. 3 shows a second packaging mode in which a reel is wrapped with a cellulose wadding (8) in layers of a stretched film (9).

The stuffing layers (6) and (8) shown in FIGS. 2 and 3 are adhered to the paper surface layer (11) on one side as shown in FIG. 4 or both sides as shown in FIG. To the paper surface layer (12). During the spiral wrapping, crepe paper with some stretchability is used on the paper surface (11) and the paper surface (12) to provide a change in elongation.
