Description

The present invention relates to a storage bag that is convenient for storing waste such as paper waste in one place.

Conventionally, many bags in which a paper string is configured as a mesh have been proposed. For example, there are shopping bags, undressing baskets, vegetable baskets, etc. that are made of a container with a mesh and formed into a predetermined shape using a material that can be easily disassembled in the soil, and are firmly manufactured to be used repeatedly (for example, Patent Document 1). reference.).

In addition, as a baggage carrying bag, it is a bag with rhombus meshes made of woven cotton, synthetic fiber, etc., and when it is empty, it is light and easy to carry without being bulky. There is a shopping bag that can be used (for example, see Patent Document 2).

There are backs formed by knitting a large number of leathers and the like in a mesh shape, which has good shape retention, and the mesh portion is flexible and is not easily deformed (see, for example, Patent Document 3).

There is a mesh-like container in which a mesh state is arranged on the outer periphery, a lid is attached to the upper part, a reinforcing material is attached to the side, and a rotating body is attached to the lower part (see, for example, Patent Document 4).

There is a shopping basket and a waste basket made of a polyoxymethylene striate or a copolymer thereof (for example, see Patent Document 5).

There is an unfolded handbag net bag in which a string is passed along the outer periphery of a circular or polygonal material having a mesh on the front surface and a ring is attached to the bag (for example, see Patent Document 6).

There is a newspaper storage bag that is a paper bag and includes a string for binding newspaper (for example, refer to Patent Document 7).

Since the conventional net bag described above is firmly manufactured to be used repeatedly, it is not intended for recycling but for permanent use, and its durability and cost were high. . For this reason, it has not been considered to use a large amount of material and to manufacture with the minimum necessary material. In addition, the newspaper storage bag is provided with a string for binding newspaper, but this string must be reattached inside or outside the paper bag, and since it is a bag, foreign matter is mixed inside. It was difficult to understand.

The present invention is intended to solve the problem of such a conventional configuration, and provides a throwaway (disposable) type storage bag that can be easily handled at low cost.

In order to achieve the above object, the present invention is formed by knitting a box-shaped bag body having an open upper portion into a net shape, and a plurality of strings that can be bound to opposite sides at the upper end of the bag body. A storage bag comprising an extended paper string is provided.

The second means for solving the problem is to provide a storage bag in which the net is in the form of a mesh composed of warp and weft, and the crossing portion is connected through one thread between the other threads.

Further, a third means for solving the problem is to provide a storage bag in which the bag body is formed so as to open upward and gussets are formed at the four corners.

The present invention is suitable for treating a large number of paper scraps to be disposed of, such as crushing old decorative boxes of various sizes, such as papers, especially confectionery boxes, to form net bags without having to align the shapes. Since they can be stacked, and they have a bag-like binding string, they can be easily bundled and arranged, and the packaging workability can be remarkably improved.

Furthermore, since it is a mesh, it is lightweight and can be easily found even if foreign matter is mixed.

Since the net bags are all made of paper, the entire packaging can be recycled as paper, and can be recycled as resource waste as it is, which can also be expected to reduce the environmental burden. In addition, since the paper thread is used, there is an effect that the manufacturing cost can be reduced. Considering these things, it can be expected to be regarded as one of the ecological measures while reusing resources.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The box-shaped net bag body shown in FIG. 1 is formed by alternately knitting warp yarns 1 and weft yarns 2, and a cube whose upper part is opened, and a plurality of strings 3 and 4 that can be bound to each other are extended on the upper part of the bag body. FIG. 2 shows an inverted triangular gusset 5 formed at the four corners of the side surface of the cube.

The base paper constituting the present invention can maintain the tensile strength necessary for the paper string by adjusting the raw material so that 70% or more of the raw paper is coniferous kraft pulp. Moreover, waste paper pulp can also be mix | blended in the range which does not impair intensity | strength.

The base paper constituting the present invention may be a single-layer paper composed of 100 percent of softwood kraft pulp or a mixed paper of a plurality of pulp components, and may be a two- to three-layered laminated paper.

Further, the above-mentioned base paper is slit into a winding, cut into a tape shape, set into a twisting machine and twisted to be processed into a paper string. It is preferable to twist some of the paper strings used in the present invention, but one may be used from the viewpoint of cost.

The net yarn constituting the present invention is made of recyclable paper, and a twisted cord, a plain weave cord, and the like are suitable. In addition, in order to obtain a high strength paper string, an enhancer that can enter the same recycling process as paper may be kneaded or sprayed on the paper string, and the thickness of the paper string is not particularly limited. The diameter is preferably 1 to 10 mm from the viewpoint of ease of handling. In order to produce the storage body having the mesh of the present invention using the above-described paper string, a knit net is knitted into a knotted or non-knotted net by a normal net manufacturing technique using a knitting netting machine.

The mesh is a mesh formed by the warp 1 and the weft 2 in FIG. 1, or is knitted in a rhombus as shown in FIG. 3, and the crossing portion is made of paper by passing the other yarn between one yarn as shown in FIG. Reinforce with recyclable glue. Further, as shown in FIG. 7, knots that do not come apart from each other are formed, or further glued to the intersection with a strong and hard-to-remove glue.

The size of the mesh is preferably 1 to 100 mm on a side. If the mesh is too large, small papers may fall. If the mesh is made smaller than necessary, the cost is too high. It is necessary to keep it to the minimum necessary.

The gusset 5 in FIG. 2 requires gussets when not utilizing the elasticity of the mesh, and is composed of four corners on the side of the mesh bag body, with an inverted triangle of 2 to 30 mm at the top and 0 mm at the bottom. To do. This gusset is used to easily fold the upper part of the net bag to the outside of the upper part of the container when the mesh bag body is used in contact with the container as shown in FIG.

When the net bag body is used at home, it is preferable that the bottom face is a cube of newspaper newspaper size (270 mm × 200 mm), and the size is changed according to the application.

The binding strings 3 and 4 in FIG. 1 are formed by extending a plurality of strings that can be bound to each other on opposite sides of the upper end of the bag body. The length of the cable tie 3 in FIG. 1 is 100 mm or more. The length 4 in FIG. 1 is 135 mm or more. The number of the binding ties 3 and 4 is preferably 2 to 6 on one side.

As the method of using the net bag body, since the shape of the net bag body is flexible, as shown in FIG. 5, for example, the net bag body is attached to an empty container such as an old newspaper stocker, and the upper part of the net bag body is attached. Fold it outside the top of the container. Moreover, since the binding strings 3 and 4 hang down, it is desirable to temporarily fix with the adhesive tape. If the paper is made fine, there is no risk of falling out of the mesh if it is normal paper. However, if necessary, large papers are placed on the bottom, small papers in the middle, and large papers on the top. It is possible to prevent detachment, and it is easy to tie with a tie and facilitate packaging.
