Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaging container, and more particularly, to a packaging container that protects a package from an impact applied to the container by holding the package to be separated from the wall of the container.
[0002]
[Prior art]
Conventionally, boxes made of foamed polystyrene or corrugated cardboard boxes with corner pads are used as packaging for transporting and storing ceramics, glass products, electrical / electronic equipment, precision machinery parts, and other sensitive items. Alternatively, a box is filled with a rose-shaped cushioning material or a sachet filled with the cushioning material. However, the foamed plastic used for such packaging has a problem in disposal after use.
[0003]
For this reason, efforts are being made to reduce the amount of packaging material used and to facilitate disposal and incineration. As one manifestation, so-called “hammock packaging” has been proposed and partially put into practical use (see Patent Documents 1 to 4). For example, as shown in FIGS. 10 and 11, “hammock packaging” means that a package J100 is sandwiched from above and below by a pair of supports J10 in which an elastic sheet J12 is stretched on a plate-like frame, and the entire container J20 is stored. It is a packaging form in which the article to be packaged J100 is held in the space inside the storage container J20 while being separated from the wall of the storage container J20.

(Other embodiments)
In the above-described embodiment, a flat sheet is used as the elastic sheet 12. However, the present invention is not limited thereto, and an embossed sheet can be used. When the embossed molded sheet is used as an elastic sheet, it is easy to follow the shape of the packaged object, and the buffer holding capacity can be increased. The embossed molded sheet is obtained by embossing a plastic film to form a large number of protrusions, or a flat plastic film bonded to one or both surfaces of a plastic film having the protrusions.
[0037]
In addition, as shown in FIG. 7, a cushioning material 90 may be installed at the end inside the storage container 20. Thereby, even when the packaged object 100 with unevenness is stored in the guide groove 21 at the end, the packaged object 100 can be prevented from directly touching the inner wall surface of the storage container 20. As the cushioning material 90, a bag-like container that is filled with air and inflated can be used. In this case, it is preferable that the cushioning material 90 is installed in the storage container 20 in a state where the air is removed, and air can be sealed after the installation so as to have an appropriate buffering action.
[0038]
Moreover, in the storage container 20 of the said embodiment, although the several pair of guide groove 21 was provided, the number of the guide grooves 21 can be changed as needed. For example, as shown in FIG. 8, a pair of guide grooves 21 can be formed on the inner wall surface of the storage container 20 by using the middle frame 23 in which one slit 23 b is formed between two protrusions 23 a. it can.
[0039]
Moreover, in the said embodiment, although the inner frame 23 and the outer case 24 which comprise the storage container 20 were comprised separately, not only this but the guide groove 21 should just be formed in the inner wall of the storage container 20. FIG. For example, as shown in FIG. 9, a guide is provided on the inner wall of the storage container 20, whereby the guide groove 21 can be formed.
[0040]
Moreover, the storage container 20 of the said embodiment can be provided with a lid on the upper surface of the storage container 20 as necessary. Furthermore, the bottom surface of the storage container 20 of the above embodiment can be omitted if unnecessary.
[0041]
Moreover, when the packaged item 100 is relatively light, the guide groove 21 may be stored in a horizontal state.
[0042]
In the above-described embodiment, the holding cartridge 10 is folded in two. However, the number of folding may be increased as necessary, such as tri-folding.
[0043]
Further, in the configuration in which the bottom surface of the middle frame 23 does not exist, the four corners that connect the side surfaces of the middle frame 23 may not be in a fixed state but may be freely rotatable around the connection portion. Thereby, the middle frame 23 can be easily folded when not in use. Even in such a configuration, if the middle frame 23 is arranged inside the outer box 24, the middle frame 23 is fixed by the outer box 24.
