JP3003200U - Dunnage - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a dunnage that is easy to be used repeatedly without increasing the volume considerably even when stacked in large numbers when not in use. Further, the present invention provides a dunnage that is easy to mold, has high strength, is highly versatile, and can reduce the amount of dust generated. A dunnage formed by arranging a hemispherical shape having a convex surface and a concave surface and a flat upper surface and a truncated cone shape at an appropriate interval on a resin hard plate that is easy to mold.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dunnage for preventing cargo from collapsing after being loaded on a truck, a container, a freight car, or the like.

[0002]

[Prior art]

 Conventionally, air dunnage (airbags), empty pallets, foam cushioning materials, wood, etc. have been used as dunnage to fill the gaps in cargo. The air dunnage and empty pallets are returned to the shipper for repeated use, but others are disposable.

[0003]

[Problems to be solved by the device]

 The conventional one has the following drawbacks. Since foamed cushioning materials, wood, etc. are disposable, there is a problem of waste treatment. The air dunnage is small when returned and is very good for repeated use, but it takes time to inflate and deflate, and it must have an inflator. Empty pallets do not shrink when returned.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention suitably employs a resin hard plate (1) which is easy to mold, a hemispherical shape (2) or a truncated cone shape (3) having a convex upper surface and a concave rear surface with a flat upper portion. The dunnage is formed by arranging with a certain interval and molding.

[0005]

[Action]

 A hemispherical shape (2) with a convex front surface and a concave back surface and a flat top surface (3) is arranged on a resin hard plate (1) that is easy to mold at an appropriate interval, and the molded dunnage is used. Use one or several sheets between the walls of the truck and the cargo and between the cargo, or between the cargo so that their surfaces face each other. The thickness, which is the height of the protrusion times the number of sheets, fills the space. After the end of use, a large number of sheets are stacked, but since the irregularities of the hard plate fit together, the plate thickness is added to the height of the first convex portion, and the volume does not increase significantly.

[0006]

【Example】

 A hemispherical shape (2) or a truncated cone shape (3) having a convex front surface and a concave rear surface and an upper flat surface is arranged on a resin hard plate (1), which is easy to mold, at an appropriate interval to mold. The size and spacing of the uneven hemispherical shape (2) or frustoconical shape (3) with a flat upper part is determined by the size of the contact surface of the cargo and its shape. The material and thickness of the resin hard plate (1) are determined according to the required strength and hardness. As a processing method, a resin hard plate is generally pressed or pressure molded, but there is also a method of simultaneously molding the plate by rotational molding, RIM molding or the like. The unevenness is generally arranged in a zigzag pattern on the plane, but when it is desired to fold it and use it, it is arranged in a grid pattern. If the size of the unevenness is not limited to one type in one dunnage, and the large and small unevennesses are combined and arranged, the height can be adjusted when several sheets are stacked as shown in FIG. It will be easier. A hole for draining water is provided at the tip of the unevenness so that water does not collect even when placed outdoors. It is also possible to use the holes to fix the surfaces with a wire or the like so that they will not be displaced when the surfaces are stacked and used. The edges of the plate and the protrusion should be sufficiently rounded (R) to prevent damage to the cargo.

[0007]

EFFECTS OF THE INVENTION The dunnage of the present invention is piled up for storage and transportation, but its volume is very small and it is easy to organize and store. Since it is returned to the shipping source and used repeatedly, logistics costs can be reduced. Since the dunnage of the present invention is easy to use repeatedly, it can reduce the generation of dust and save resources. The dunnage of the present invention can be used for several heights by combining different sizes of unevenness in one sheet without increasing the number of different heights.
