Description

  The present invention relates to a packaging member for transporting a packaged body having various shapes, such as medical equipment, various precision machine parts, semiconductor products, glass products, and the like. It is a cushioning material for interposing between the transport containers and protecting the package body from external forces such as impacts, and packing the package body consisting of various products and parts whose shape and dimensions are not particularly determined, The present invention relates to a universal air cushioning material that is suitably used when transporting in different environments over a long period of time.

  Conventionally, foamed polystyrene products are used for packing regular-sized mass-produced products. However, as packing materials or cushioning materials for a wide range of applications, newspapers, cloth, chip-like foamed polystyrene, bubble film, etc. It was useful because it could be used regardless of shape.

  However, in each of the above-mentioned cushioning members, for example, a molded product of polystyrene foam is used corresponding to each product. Therefore, after use, it is not possible to change applications other than disposal, and versatility. Even in chip-like foam polystyrene, bubble sheets (air caps) and newspapers and cloths that are excellent in the case of final disposal as waste, it becomes a considerable amount, from the viewpoint of global environmental protection and energy saving in recent years, It is a problem that cannot be overlooked easily.

Therefore, recently, a bag-like air cushioning material (for example, a bag-like air cushioning material provided with an air inlet having a special check valve function at one end thereof is formed into a bag-like shape by heat-sealing the outer edges of the two synthetic resin films. ), And an air mat-like cushioning material (for example, see Patent Literature 2) comprising a plurality of small air chambers provided with a linear or dotted welding wire inside the bag-like cushioning material. Already widely used as a bag-like air cushioning material made of a thin film synthetic resin in which an air pressure of 3 Kpa / cm ^{2 to 5} Kpa / cm ² is enclosed. This bag-like air cushioning material has excellent properties as a protective packaging for various parts and products while maintaining versatility as a packaging material, as a gap filling material for general goods, and as a cushioning material for materials. In addition, it is folded into a sheet shape when not in use, the storage space is compact, the disposal process is easy, and the convenience is excellent.

  However, the synthetic resin bag-like air cushioning material has excellent characteristics as described above as a substitute for chip-shaped foamed polystyrene and bubble sheets for cargoes consisting of various types of parts and products having various shapes. However, it is difficult to stably package precision parts with a specific shape with a square or polygonal outer shape, glass products that are vulnerable to impact, or easily damaged cylindrical or columnar cargo, etc. When transporting under conditions, there is some concern about its reliability, and in order to wipe it off, a larger amount of bag-like air cushioning material will be used, resulting in an increase in the size of the transport container. In order to compensate for various gaps between the product to be transported and the packaging container, the bag-like air cushioning material is desirably individually compact, and the air to be sealed is also at a relatively low pressure. It has been requested is. Therefore, when transporting and storing for a long time in an area where the temperature changes drastically, for example, in a cold region, the air pressure of the bag-like air cushioning material decreases, or conversely, the bag-like air cushioning material bursts in a high-temperature zone. New problems have arisen, such as the loss of function as a cushioning material.

Therefore, recently, many air cushioning materials have been proposed in which cargo such as precision parts is completely wrapped with an air cushioning material and interposed between the transport containers and exhibit a stable cushioning function.
As an example, a synthetic resin air cushioning material having a plurality of elongated air chambers extending in the lateral direction is folded by folding the elongated air chamber into a cylindrical shape and its partial welded portion. Is provided with an air cushioning material (see, for example, Patent Document 3) that covers the entire packaged body with the air chamber, and an air chamber called a vesicle that is continuous in the left-right direction. A wound-type air cushioning material (see, for example, Patent Document 4) in which a step is formed at the boundary between the portion and both end portions has been proposed. In the former, the packaged material is completely wrapped by the cushioning material, and in the latter, There has been proposed an air cushioning material that wraps while supporting the periphery of an object to be packed by a stepped portion, or is sandwiched from the left and right in some cases.
Japanese Examined Patent Publication No. 7-117171 (pages 1 to 3, FIG. 2) Japanese Utility Model Publication No. 6-37149 (pages 1 to 5, FIG. 4) JP 2003-137352 A (pages 1-8, FIGS. 1-15) Japanese Patent Laid-Open No. 2003-63567 (Pages 1-7, FIGS. 1-7)
