Abstract

PURPOSE:To provide a cushioning material free from harmful gas, easy to incinerate for disposal, reusable for recycling of discarded papers and easy to vary the cushioning action by a method wherein the paper cylinder consisting of discarded papers are cut into pieces of a suitable length and a lidded paper-made case or bag is packed with the cut paper cylinder pieces in a randomly orienting manner. CONSTITUTION:Paper cylinders are cut into pieces of a suitable length and a liner paper-made case 2 with a lid 3 is packed with such cut paper cylinder pieces 1 in a randomly orienting manner by loose arrangement, adhesive attachment or compression molding by a die using adhesive. The cut paper cylinder piece 1 varies in elasticity (cushioning action) and rigidity with the number of times that the paper is wound to form the cylinder and the inside diameter and length of the cylinder. Since there are differences in the elasticity (cushioning action) and the rigidity between the outer peripheral and longitudinal directions of the cylinder, the cut paper cylinder pieces are attached together in a randomly orienting manner to permit the action of cushioning material to be varied. Since discarded papers are used, the cushioning material is economical to manufacture, easy to incinerate for disposal, free from harmful gases and reusable as another material for recycling supply.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material that can be used as a core material for packaging and soundproofing materials.

[0002]

2. Description of the Related Art Conventionally, when articles are transported and stored, a cushioning material is incorporated in a packaging container to fix the articles to be stored,
I try to absorb the shock from the outside. As such a cushioning material, generally, a plastic foam such as styrofoam is often used.

[0003]

Although the conventional plastic cushioning material has various advantages such as light weight, high cushioning effect, and good appearance, like other plastic products, There were numerous difficulties in processing after use. That is, the cushioning material is discarded after transportation and storage (after the load is released) without being reused, but the plastic cushioning material is not only flame-retardant, Once started to burn, the temperature becomes extremely high, which shortens the useful life of the refuse incinerator and produces toxic gases such as chlorine and cyan, which causes pollution. On the other hand, recently, there is a cushioning material that uses paper such as cardboard paper, but since recycled paper is used, it costs much to manufacture the base paper material,
In addition, since it has a typical cross-sectional shape (mountain shape of flute), it has a drawback that it is difficult to easily change elasticity (cushioning property).

Since the present invention uses waste paper as a material, during the incineration process after use, it is possible to reduce the service life of the incinerator due to high temperature combustion, such as a plastic cushioning material, and to generate toxic gases such as chlorine and cyan. It can be incinerated easily without it. It can also be recycled as waste paper material after use. Furthermore, the present invention directly uses recycled paper, and can be manufactured at a lower cost than other paper cushioning materials such as cardboard paper using recycled paper. Further, since it has a wrapping paper structure or a spiral twisted paper structure, it is also possible to provide a cushioning material whose elasticity (buffering property) can be easily changed by changing the number of paper windings or the spiral diameter. is there.

[0005]

Therefore, according to the present invention, a wrapping paper cut piece obtained by cutting a wrapping paper cylinder made of waste paper into an appropriate length is attached to a paper box or bag having a lid with an adhesive. Are bonded and packed so that they face in random directions, and a paper box or bag with a lid is installed in the mold, and a paper cylinder made of waste paper is placed in the appropriate length. The wrapping paper cut pieces obtained by cutting into pieces are packed so as to be oriented in random directions, adhered with an adhesive, and compression-molded. This is a means for solving the problem.
Further, the present invention is a twisted paper cut piece obtained by cutting a spiral twisted paper formed by spirally forming a twisted paper made of waste paper, is an adhesive agent in a paper box or bag with a lid, and these are randomly oriented. It is made by adhering so as to face and packed, and twisted paper cut pieces made by cutting spiral twisted paper formed by forming twisted paper made of waste paper into a spiral shape are bonded and oriented in random directions A paper box or bag having a packed lid is mounted in a mold and compression-molded, which serves as a means for solving the problem. Further, according to the present invention, a plurality of spiral twisted papers formed by spirally forming a twisted paper made of waste paper are arranged side by side on a wrapping paper glued to the peripheral portion, and adhesively formed in the lengthwise direction of the same burning paper. It is made of paper and is used as a means for solving the problems.

[0006]

Since the present invention is a cushioning material having a paper-wrapping tube structure or a spiral twisted paper structure, it has high elasticity (cushioning property) also in the cylinder outer peripheral direction or in that direction, while it has high rigidity in the cylinder longitudinal direction. Its elasticity (cushioning property) and rigidity can be adjusted by the number of windings of the paper, the inner diameter of the cylinder and the cylinder length, and the elasticity and rigidity can be adjusted by the size of the spiral diameter and the number of spirals. In addition, in the case of the wrapping paper structure as described above, since the elasticity (cushioning property) and the rigidity have directionality, by arranging or adhering the cut piece of the wrapping paper to the tan dam, an appropriate elasticity (cushioning property) and A cushioning material having rigidity can be obtained. Furthermore, since this wrapping paper cut piece is cut into an appropriate length in the form of pellets, an arbitrary shape can be obtained by a compression molding die with a die. In addition, since the spiral twisted paper is randomly oriented and joined, it has appropriate elasticity (buffering properties) and rigidity, and even if it is wrapped as it is as a spring-shaped cushioning material, it has excellent cushioning properties. There is.
