[0001]

[Industrial applications]

 The present invention relates to an article partition holding member, and more particularly to an article partition holding member used for protecting various articles during storage and transportation.

[0002]

[Prior art]

 For general industrial parts, automobile parts, home electric appliances parts, OA equipment parts, etc., it is necessary to prevent the surface of the parts from being scratched during the storage and transportation process, both in terms of product value and function. There are many things that cannot be done. Conventionally, such parts are stored and packed one by one in vinyl bags, expanded polyethylene storage bags equipped with a surface protection function, etc. Insert one part into each square of the partition member, or use a molded resin holding member made of foamed resin that is split-molded according to the shape of the part, and use the mold holding member to insert the parts one by one. This is done by holding the coating.

[Problems to be solved by the device]

 The partition holding of the parts by the partition member is convenient for storing and transporting a large number of parts as one aggregate, but the size of the girder shape of the partition member cannot be changed or its change is possible. Requires disassembly and reassembly, and lacks the large degree of freedom for storable parts.

For this reason, conventionally, it is necessary to prepare a dedicated partition member for each component, and when handling a wide variety of components, it is necessary to prepare partition members of numerous sizes and in the shape of a double girder. However, its handling becomes complicated, which hinders the rationalization of inventory management. Further, since the mold holding member is also dedicated to each part, there is the same problem as in the case of the partition member described above. The present invention has been made in view of the above-mentioned problems, and is excellent in flexibility with respect to the size of a storable component (article), and easily and reliably protects large and small articles in an intact state. It is an object of the present invention to provide an article partition holding member that can be held.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the article partition holding member according to the present invention has a trapezoidal shape or a triangular shape repeatedly bent when viewed from the side, and each trapezoidal or triangular valley is an article. Is defined by an accordion structure capable of expanding and contracting in a direction in which a space between both side walls of the article receiving space increases and decreases.

Further, the article partition holding member according to the present invention is constituted by a multilayer structure of a soft material having a surface protecting function and a strength holding material having higher rigidity and flexibility than the soft material described above. You may

[Work]

 According to the above-described configuration, the article partition holding member expands and contracts in the direction in which the space between both side walls of the article receiving space increases or decreases, thereby changing the inner volume of each article receiving space, and the change in the inner volume causes each article to be changed. It is possible to store large and small items in the receiving space, and it is possible to partition and hold large and small items in each item receiving space.

[0008]

【Example】

 Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 3 show an embodiment of an article partition holding member according to the present invention. The article partition holding member 1 has a shape that is repeatedly bent into a trapezoidal shape when viewed in a side view, and each trapezoidal valley defines an article receiving space 2 that individually receives an article G, and an article receiving space. The accordion structure is capable of expanding and contracting in the direction in which the distance between the two side walls increases or decreases, that is, in the left-right direction when viewed in the figure.

The article partition holding member 1 includes a surface protection sheet 3 made of a soft material having a surface protection function such as expanded polyethylene, cross-linked expanded polyethylene, expanded polypropylene, expanded polyurethane, and non-woven fabric, expanded polystyrene, non-expanded polystyrene, It is composed of a two-layer structure including a strength retaining sheet 4 made of a strength retaining material having higher rigidity and flexibility than the soft material such as non-foaming or low foaming polypropylene and non-foaming vinyl chloride. The material forming the surface protection sheet 3 may have a density of 0.025 to 0.05 g / cm ² and a thickness of about 1.0 to 3.0 mm. Further, the purpose of the strength holding by the strength holding sheet 4 is to prevent the articles G put in the article receiving space 2 from moving or being biased in the transportation process.

The surface protection sheet 3 and the strength holding sheet 4 are bonded to each other by using a hot melt adhesive in the case of bonding different materials, or in the case of the same material bonding such as polypropylene-based bonding. It may be performed by adhesion by melting. In the case of foamed polypropylene, there are combinations of low magnification and high magnification. In this case, since the article partition holding member 1 is made of a single resin, the surface protection sheet 3 and the strength holding sheet 4 are collected in a composite state. Can be effectively reused.

Also in the case of different materials, if the expanded polystyrene sheet and the crosslinked expanded polypropylene sheet are combined, both sheets can be easily peeled off by adhesion with a weak adhesive agent. The sheets can be easily separated and collected for reuse. When the article partition holding member 1 has a two-layer structure of the surface protection sheet 3 and the strength holding sheet 4, the article partition holding member 1 is formed so that the surface protection sheet 3 forms a valley surface layer that defines the article receiving space 2. Bending is performed.

As shown in FIGS. 1 to 3, as the article partition holding member 1 expands and contracts in a direction in which the distance between both side walls of the article receiving space 2 increases and decreases, the inner volume of each article receiving space 2 changes. However, due to this change in the internal volume, the size of the article G that can be placed in each article receiving space 2 changes. As a result, the article partition holding member 1 holds each article in the space 2 and holds articles G of various sizes.

As an example, the article partition holding member 1 having the accordion structure as described above uses a normal vacuum forming machine and a forming die to vacuum a tapered concave-convex box body as shown in FIG. It can be obtained by molding and cutting with a nichrome wire heater or the like along the line indicated by symbol C in FIG. Further, although not shown in particular, it is also possible to insert the laminated original sheet between the molds and manufacture it by thermocompression molding.

FIG. 5 shows another embodiment of the article partition holding member according to the present invention. The article partition holding member 1 in this embodiment has a three-layer structure in which the surface protection sheets 3 are joined to both sides of the strength holding sheet 4, and the lower opening troughs are received in addition to the upper troughs. It is supposed to be space 2. 6 to 8 each show an example of combined use of the article partition holding member 1 having a three-layer structure. As shown in the drawings, the article G can be held without waste of space in any case. Understand that

In the above-described embodiment, the article partition holding member 1 has a trapezoidal shape when viewed from the side, and the article partition holding member 1 according to the present invention is bent. The side surface shape is not limited to the trapezoidal shape, and may be a trapezoidal shape and a triangular repeating shape as shown in FIG. 9 or a triangular shape as shown in FIG. Good.

[0016]

[Effect of device]

 As can be understood from the above description, according to the article partition holding member of the present invention, the content of each article receiving space is expanded by expanding and contracting the article partition holding member in the direction in which the space between both side walls of the article receiving space increases or decreases. Since the product changes, it is highly flexible with respect to the size of the articles that can be stored in each article receiving space, and it is possible to easily and reliably hold a variety of small and large articles in the intact state. This eliminates the need to manufacture partition members for each part, and promotes cost reductions for holding product partitions and rationalization of inventory management.

Further, since the article partition holding member is composed of a multilayer structure of a soft material having a surface protection function and a strength holding material having higher rigidity and flexibility than the soft material, it is necessary. Good product partition holding strength is ensured, and the stored products are safely partitioned and held with the surface protected.
