JPH0924973A - Cushion material for packing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a cushion material for packing which is inexpensive and has low pollution by constituting a cushion part of wood chips and forming the cushion material to provide flexibility between the cushion parts so that the cushion parts are at desired positions. SOLUTION: Thin synthetic resin pieces 1, 2 having airtightness and flexibility are overlaid vertically and wood chips 3 are put between the thin pieces 1, 2 together with air. The thin pieces 1, 2 are fused approximately at the center in a lengthwise direction of the pieces 1, 2 to divide the wood chips 3 by the fused part, thereby providing cushion parts 5, 5. Alternatively, a space between the thin pieces 1, 2 is deaerated to seal the wood chips 3 in a vacuum state, providing a cushion part 5. Then the wood chips 3 are divided between the thin pieces 1, 2, and the cushion parts 5, 5 are formed so that they can stand with a partition as a fold line. Such a cushion material serves as a cushion due to elasticity of the wood chips 3 and has little influence to environments at the time of disposal. In addition, adjustment of an air amount between the thin pieces 1, 2 can adjust elasticity of the cushion material.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-pollution packing cushioning material which is used by being interposed between an article and a packaging container in order to protect the article from vibration, impact, etc. during transportation.

[0002]

2. Description of the Related Art Conventionally, a cushioning material for packing is made by molding foamed polystyrene corresponding to the shape of an article to be transported.
It is generally known that a plurality of synthetic resin films are adhered to each other and a large number of air bulges are formed between the films, and a corrugated cardboard is bent.

[0003]

Most of conventional packing cushion materials are made of synthetic resin. Therefore, there is a problem that petroleum is consumed in the manufacturing process and that it is polluted in the disposal. Further, the one using corrugated cardboard has a problem that it is not preferable as a one-time disposable cushioning material for packaging because the corrugated cardboard is used to make paper.

In view of the above, according to the first to fifth aspects of the present invention, attention is paid to the fact that the wood chips produced during logging, lumbering, etc. have elasticity, and the use of wood chips as the cushioning material reduces the manufacturing cost. It is an object of the present invention to provide a cushioning material for packaging which is low and has low pollution.

[0005]

In order to achieve the above-mentioned object, in the invention according to claim 1 of the present invention, the cushion portion is made of wood chips so that the cushion portion has a desired positional relationship. In addition, it is characterized in that the cushion portions are formed so as to have a bendability.

According to a second aspect of the present invention, the wood chips are sealed between the thin pieces having airtightness and betability to form a cushion portion, and the wood chips are divided between the thin pieces as necessary. However, it is characterized in that the cushion portion is formed so that it can be undulated by using the dividing line as a folding line.

The invention according to claim 3 is characterized in that the wood chips are deaerated between the thin pieces and sealed in a vacuum state to form a cushion portion.

According to a fourth aspect of the present invention, one side surface is formed into a substantially flat shape and the other side surface is formed with irregularities, the convex portion is a cushion portion formed of wood chips, and the concave portion is bendable or cuttable. It is characterized by having done.

According to a fifth aspect of the present invention, the wood chips forming the convex portion are formed by binding and solidifying.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION In the embodiment of the invention shown in FIGS. 1 and 2, square-shaped synthetic resin thin flakes 1 and 2 having airtightness and betability are vertically polymerized, and the thin flakes 1, Between the two, wood chips 3 are put together with air. The upper and lower thin pieces 1 and 2 are fused along the lateral direction at approximately the center of the thin pieces 1 and 2 in the longitudinal direction, and the wood chips 3 are divided by the fused portions 4 to form cushion portions 5 and 5. .

An embodiment of the invention shown in FIG. 3 will be described. For simplification of explanation, the same reference numerals are used for the portions having the same functions as those shown in FIGS. The wood chips 3 are sealed in a vacuum state between the thin pieces 1 and 2. Since other configurations are similar to those of the embodiment of the invention shown in FIGS. 1 and 2, the description thereof will be omitted. The elasticity of the cushion portion 5 is determined by the ratio of the air and the wood chips 3 sealed between the thin pieces 1 and 2.

[0012]

EXAMPLE In the example of the embodiment of the invention shown in FIGS. 1 to 3, as shown in FIG. 4, it is bent at a dividing line to abut on a corner portion of a transported article 9 to protect it.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the invention shown in FIGS. 5 to 8 will be described. An upper surface is opened, and an upper end edge of a container 6 made of a thin piece having a trapezoidal vertical cross section is continuously provided, and the continuously provided portion 7 is formed so as to be bendable. It does not matter whether the container 6 is made of paper or synthetic resin, but it is preferably made of paper from the viewpoint of low pollution. The wood waste 3 is contained in the container 6. The wood chips 3 may be bound and solidified with a paste. Slice 8
Is attached to the continuous portion 7 so as to cover the upper opening of the container 6. The thin piece 8 may be made of paper or synthetic resin as long as it has a bendability, but it is preferably thick paper or corrugated paper from the viewpoint of low pollution.

[0014]

EXAMPLE As shown in FIGS. 7 and 8, when used, it is cut into a desired shape along the continuous portion 7 and used.

[0015]

EFFECT OF THE INVENTION Since the present invention is formed by putting wood chips between the thin pieces having a watertight and airtight property, the elasticity of the wood chips serves as a cushioning material, and it has low pollution at the time of disposal. effective. In addition, the elasticity of the cushion material can be adjusted by adjusting the amount of air between the thin pieces. Further, there is an effect that the weight is light and the cushioning property is good.

Further, since one side surface is made flat and the other side surface is made uneven, and the convex portion is formed on the cushion portion made of wood chips, the continuous portion is bent or the continuous portion is formed. There is an effect that it can be cut into a desired shape and can be applied to any shape.
