Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition cushioning material suitable for accommodating articles such as bottles and cans in which food and drink are enclosed in a gift wrapping box and the like, and a method for producing the same. Relates to a packaging box in which is disposed.

[0002]

2. Description of the Related Art In general, when transporting and storing articles such as bottles and cans, it has been conventionally used for the purpose of preventing breakage of such articles from being made of a resin box or a corrugated cardboard box. Are manufactured and fixed, fixed by upper and lower pats (there are styrene foam and pulp mold as materials), and use of a partition cushioning material as seen in assorted packaging boxes for gifts. . However, in the above-mentioned measures, there is a dislike that the cost is relatively high, and there is a possibility that the buffering effect and the fixing stability may be insufficient for the transportation of relatively heavy beverage bottles which are easily broken. Was.

[0003] In the above-mentioned measures, styrofoam has a problem in the treatment after use (dust treatment), and also has difficulty in packaging (aesthetics) and in taking in and out of articles. Said,
The partitioning cushioning material used for gift wrapping boxes and the like has a function of partitioning a predetermined number of articles of the same type or different types by arranging them in a plurality of rows and / or a plurality of rows, and a function of mitigating an impact on them. Is required. Conventionally, as a buffer material of this kind, a pulp mold (soft mold) made of pulp or waste paper in addition to a resin (A-PET, PP filler foamed styrene foam with calcium carbonate, polyvinyl chloride, etc.) Is used.

[0004] A comparison between a resin partition cushioning material and a pulp mold material shows that when the resin material breaks due to a difference in material, the wound becomes sharp and the injury is likely to occur. The product made of pulp mold does not have such a drawback, and the product made of pulp mold has a higher buffering capacity than the resin product, and is suitable for storage of fruits and vegetables because of its excellent permeability and moisture absorption. It has the advantages of being able to use waste paper, having high recycling efficiency, being easy to process after use, and being environmentally friendly.

[0005]

Therefore, in transporting and storing articles such as bottles and cans, it is recommended to use a pulp mold partition cushion.
The conventional partition buffer has the following problems. That is, FIGS. 13 to 15 show a general pulp mold partitioning cushioning material 100 conventionally used for gift packaging boxes and the like. In the illustrated example, the partition cushion 1
00 is, for example, half a dozen beer bottles 200 (6
Book), which is used to be housed in a packaging box 5 composed of a box body 5A and a lid box 5B, and has six rows of recesses corresponding to approximately half a circumference (semicircular cross section) of the small bottle 200. .. Are arranged side by side.

[0006] Each of the peripheral support portions 110 has an uneven buffer portion 112 having a height difference in a direction perpendicular to the peripheral side portion of the small bottle 200 at a portion supporting the lower half of the small bottle 200 (FIG. 11). Along the upper and lower sides of the small bottle 200, and the portion supporting the upper portion of the small bottle 200 also has an uneven buffer portion 114 having a height difference in a direction perpendicular to the peripheral side portion of the small bottle 200 and a mouth receiving portion. 116 are provided.

However, in the conventional partition cushioning material 100 having the above-described structure, the article (small bottle 200) is supported in a posture in which the article (small bottle 200) is laid sideways (flat posture). In addition, the transportation and storage costs are somewhat inconvenient, and the transportation and storage costs are increased. When the number of articles is large, the length of the article becomes longer in the horizontal and vertical directions. It is easy to bend and the fixing stability of the article may be impaired.Since it supports only half a circumference of the article, the cushioning effect in the radial direction of the article may be insufficient, and the cushion in the height direction of the article may be insufficient. There is a problem that the effect may not be sufficiently obtained.

The volume ratio of the partitioning cushioning material is generally defined. However, in the case of the pulp mold, the draft angle at the time of releasing from the mold is considerably larger than that of the resin. Therefore, depending on the required volume ratio, there may be a case where it is not possible to produce a partition buffer material having a desired volume ratio with a conventional type in which the shape does not change between molding and use. Therefore, there is a demand for a new type of partition cushioning material that can meet the above demand. Depending on the stored articles, there is a case where it is required to further increase the buffer capacity than the current state.

There is also a need for easy handling, easy deployment in a packaging box, and improvement in the stability of the packaging box without using additional fixing means. The present invention has been made in view of the problems described above,
The purpose is to reduce the installation plane area, reduce the transportation cost and storage cost, and obtain the structural strength that can withstand even if the total weight of the article is large, as well as the necessary and sufficient fixing stability and A buffer effect is obtained, and it is easy to manufacture and handle, a desired volume ratio is obtained, and at the same time, it is easy to deploy in a packaging box, and the fixing stability to the packaging box is improved without using a separate fixing means. The present invention is to provide a new type of cushioning material for a partition, a method of manufacturing the same, and a packaging box in which the same is arranged.
