Abstract

(57) [Summary] [Purpose] To provide a cushioning material for packaging that is not likely to generate harmful gases even when incinerated and has an excellent cushioning effect. [Structure] The first device is a molded piece 1 that is made of melted waste paper as the main raw material and is shaped like a plate or a short string and has a curved surface. The third idea is that a large number of the molded pieces 1 are partially glued together to form a molded main body 3 having a desired shape.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a pollution-free packaging material that can replace packaging cushioning materials made of styrofoam resin. This relates to shock absorbers.

0002

[Conventional technology]

As a cushioning material for packaging, foamed polystyrene resin can be molded into the desired shape. However, Styrofoam resin releases harmful gases when it is incinerated. I have a big problem. To solve this problem, we use dissolved waste paper. Attention has been focused on so-called paper mud moldings as the main raw material, but compared to conventional paper mud moldings, This cushioning material for packaging uses dissolved waste paper as its main raw material and has a shape that corresponds to the shape of non-packaged items. Since it is formed into a shape, the cushioning effect will be lost unless it is made fairly thick and flexible. It was inadequate.

0003

[Problem that the idea aims to solve]

What this invention attempts to solve is to solve the above-mentioned problems and to solve the problem of incineration disposal. We use cushioning materials for packaging that have excellent cushioning effects and do not pose the risk of generating harmful gases even when It is about providing.

0004

[Means to solve the problem]

The packaging cushioning material of the present invention, which solves the above-mentioned problems, mainly contains dissolved waste paper. The raw material is a molded piece that is plate-like or short string-like and has a curved surface, and this molded piece is A large number of pieces are packaged in a bag, and a large number of the molded pieces are partially glued together. The main body is molded into the desired shape.

[0005]

[Effect]

This kind of packaging cushioning material is used for packaging boxes, containers, etc. and the items to be packaged stored in them. The material of each molded piece has its own elasticity and curved surface. The restoring force generated when the molded pieces are compressed reduces the impact on the packaged item.

[0006]

【Example】

Next, the present invention will be explained in more detail with reference to illustrated embodiments. Figures 1 to 3 show examples of the first invention, and 1 is the basic molding of the invention. The molded small piece 1 is a so-called paper mud molded product whose main raw material is melted waste paper. As shown in Figure 1, it is shaped like a plate with a curved surface like a molded potato chip. or formed into a short string shape with a curved surface as shown in Figure 2 or Figure 3. The material itself has elasticity and is flexible at least in the longitudinal direction. When pressure is applied to each molded piece 1 from the outside and it bends, its restoring force acts. It is a thing. Items configured in this way are useful when storing items in packaging boxes, containers, etc. , a loose piece is interposed between the packaging material such as a packaging box or container and the packaged object, and each molding Due to the elasticity of the material of the small piece 1 itself and when each molded piece 1 having a curved surface is compressed, The resulting restoring force alleviates the impact on the packaged items.

[0007] Next, Fig. 4 shows an embodiment of the second invention, in which a board is made of waste paper melt as the main raw material. A molded piece 1 as shown in FIGS. 1 to 3, which is in the form of a piece or a short string and has a curved surface. Pack a large number of items in paper bags, water-soluble polyvinyl alcohol, and other non-polluting or relatively harmful gases. As an aggregate placed in a bag 2 made of plastic film etc. that does not cause be. Items configured in this way are useful when storing items in packaging boxes, containers, etc. , if there are any items left in the bag 2 between the packaging material such as a packaging box or container and the packaged item. The elasticity of the material of each molded piece 1 and each molded piece having a curved surface The restoring force generated when the small piece 1 is compressed reduces the impact on the packaged item.

[0008] Fig. 5 shows an embodiment of the third invention, in which a board is made of waste paper melt as the main raw material. A large number of molded pieces 1 having a strip or short string shape and a curved surface are partially attached to the adhesive part 4. of the required shape and has an uneven part 5 corresponding to the surface shape of the packaged object. It is listed as molding main body 3. Items configured in this way are useful when storing items in packaging boxes, containers, etc. , the molded body 3 is placed between the packaging material such as a packaging box or container and the object to be packaged. The material of each molded piece 1 itself is the elasticity of The restoring force of the main body 3 alleviates the impact on the packaged item.

[0009] Thus, a molded small piece 1 as shown in FIG. 1, which is a representative example of the first invention, is manufactured. To do this, waste paper such as old newspapers is dissolved in water and a water-soluble glue is added to form a thin plate. This is then molded into a desired shape with a curved surface in an appropriate moisture-absorbing state. Since it only needs to be cut and dried, it can be provided at low cost.

0010 Furthermore, each of the above-mentioned packaging cushioning materials can be disposed of by incineration after use. Molded small piece 1 made of melted waste paper as the main raw material and shaped like a plate or short string and having a curved surface does not emit harmful gases when incinerated, so there is no need for landfill disposal, and it is useful for pollution prevention. The effect is extremely large.

[0011]

[Effect of the idea]

As explained above, this invention eliminates the risk of generating harmful gases even when incinerated. It has excellent buffering effect, and is inexpensive because it is made from waste paper. It combines the advantages it can provide and solves the problems of conventional packaging cushioning materials of this type. There are some things that have extremely great practical value.
