Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a cardboard packing structure applied to packing packed articles such as compressors.

[Prior Art] Generally, for example, when a relatively heavy packaged product such as a compressor is stacked and stored in an outer box of a cardboard for collective packaging, the weight of the upper packaged product is usually added to the lower packaged product. The vertical compressive load must be supported inside the package to prevent

Conventionally, in this type of cardboard packing, a partition plate made of wood, styrofoam, cardboard, etc. is used as a support structure for supporting the vertical compressive load of the packaged product, and this partition plate is used in a cardboard outer box. There is a configuration in which the packaged items are stacked on top of each other so that the packaged items are packaged so as to receive a vertical compressive load.

However, in such a conventional partition board used for corrugated cardboard packaging, one having a shape composed of hollow columns (30) as shown in FIG. 9 or a framework in a cross beam shape as shown in FIG. Although the shape and the like composed of the assembled partition (40) are used, none of them supports the compressive load, and the current situation is to simply limit the vertical movement of the packaged item.

[Problems to be solved by the invention] For this reason, for example, in the case where the partition plate is formed of wood or Styrofoam, not only is it costly to process the waste material after unpacking, but especially in the case of wood. If the transport or storage is continued for a long period of time, the moisture contained in the wood may impregnate the outer box of the cardboard or the pad member of the other cardboard, and the strength of the cardboard may be reduced.
In order to prevent this, a wood drying treatment step is required in advance, resulting in high cost.

In addition, if the partition plate with the shape shown in Fig. 9 and Fig. 10 is made of Styrofoam or one thin cardboard, sufficient compression strength cannot be obtained, and the compression load due to the weight of the packaged item is not obtained. Not only can not support the stacking and become unstable in stacking, but especially in the case of the shape of the hollow column (30) as shown in FIG. There was a problem that became.

The present invention has been made under the circumstances described above, and its purpose is to devise a partitioning plate that is interposed in order to support a vertical compressive load in a package in the package. Another object of the present invention is to provide a corrugated cardboard packaging structure that enables inexpensive and stable stacking.

[Means for Solving Problems] In order to solve the above-mentioned problems, the present invention has a cardboard outer box in which a large number of packaged items are stacked and housed through a partition plate and the partition In a cardboard packing structure in which a plate is placed on top of the packaged product and the packaged product is subjected to a vertical compression load, the partition plate is an outer frame, and each package is packaged in the outer frame. It is constructed by integrally forming a frame with a plurality of posts that are horizontally arranged in parallel with each other in contact with the protruding upper part of the article, and the outer frame and the posts are formed by a plurality of corrugated cardboard members bonded together. A cushioning material is provided on the lower end surface of each outer frame and column to prevent damage to the packaged product and displacement of the packaged product during transportation.

[Operation] That is, according to the present invention, with the above configuration,
An outer partition formed by bonding a plurality of cardboard members together with a pillar to form a middle partition plate, and the pillars are laterally integrated with the outer frame so that the pillars are in contact with and juxtaposed with the protruding upper portion of the packaged product. Therefore, it is possible to improve the compressive strength of the middle partition plate by the thickness of the outer frame and the pillars, and to increase the contact area of the upper and lower surfaces and the end surface with the mating material. Not only can it be carried out, but also the assembling work at the time of packing and the waste material disposal work after unpacking can be performed without trouble.
