は、耐水性を付与することもできる。The sheet material is formed in a gate shape by bending the connecting pieces at the hinge portion. Two sheet materials formed in this gate shape are used. First, a cool storage material or a freshness-retaining material, an ethylene absorbing material, and an odor absorbing material are provided in the trapezoidal space on the back side of the connecting piece in which ventilation holes of the sheet material are formed. (Deodorant), etc., and then one sheet material is attached to the three inner wall surfaces of the box first, and then the other sheet material is housed in the box and then the other sheet material is attached to the inner wall surface of the box. When both sheet materials are accommodated in the box while being attached to the remaining three surfaces of the box, a cushion material layer formed of the sheet material formed in the inner box shape is formed between the inner wall surface of the box and the accommodated article. With this, the contained article can be isolated from the cold storage material and the like, the contained article can be prevented from freezing damage, and the contents can be well protected. And, the sheet material formed in the inner box shape does not have a risk that the connecting pieces constituting the sheet material come into contact with the inner wall surface of the box to cause a positional deviation, and are formed on the periphery of each connecting piece. By the inclined surface portion, an air chamber is formed between the inner wall surface of the box and each connecting piece, and it is possible to improve the heat insulating body, and at the same time, the joint portions of the sheet-shaped sheet materials are in close contact with each other, The cardboard box is reinforced. Further, by attaching a foamed sheet to the inner surface of the corrugated cardboard box, the heat insulation can be imparted with water resistance.

設けられたものである。The sheet material 1 is made of polystyrene foam having a density of 0.1 g / cm 3 , and is composed of three connecting pieces 4, 5 and 6 which are connected by hinges 2 and 3 so that they can be bent at right angles, and the whole is rectangular. Are formed integrally using, for example, a vacuum forming method. The periphery of each of the connecting pieces 4 to 6 is formed into an inclined surface portion 7, 8 and 9 which is inclined at 45 °. Due to the existence of the inclined surface portions 7 to 9, the outer surfaces of the connecting pieces 4 to 6 are flush with each other. Certain recesses 11, 12, 13 are provided. The hinge portions 2 and 3 are formed with the valley portions of the connecting inclined surface portions 7a and 8a and the connecting inclined surface portions 8a and 9a of the opposing portions of the adjacent connecting pieces 4 and 5 and the connecting pieces 5 and 6, respectively. , A plurality of vent holes 14, 14, 14, ... With a diameter of 10 mm are provided in one or more of the connecting pieces 4, 5, 6.
以上の構成によれば、シート材１はヒンジ部2,3によ

動かないようにすることも可能である。Therefore, if two sheet materials 1 bent in a gate shape as shown in FIG. 3 are used, the connecting pieces 4 to 6 are brought into contact with the inner wall surfaces of the carton box to form the inner box state. A buffer material to be attached can be configured. And sheet material 1
Since the connecting pieces 4 to 6 are provided with the recessed portions 11 to 13, when the sheet material 1 is mounted in the cardboard box 15 (see FIG. 4), the inner wall surfaces of the box and the connecting pieces 4 are connected. The air chambers capable of accommodating the cold storage agent, the ethylene adsorbent, the deodorant, etc. are formed by the recesses 11 to 13 between the
Further, the respective joint portions of the two sheet materials 1 are in close contact with each other by the inclined surface portions 7 to 9 inclined at 45 °. In addition, the vacuum forming portion may be formed in an uneven shape according to the article to be housed in the box so that the article does not move.

強できる。The present invention is as described above, and an inner box-shaped cushioning material that can be attached to the inner wall surface of a corrugated cardboard box is formed by folding a foamed sheet material into a gate shape and using two of these folded sheet materials. Therefore, there is no concern that the cushioning material will be stably displaced in the attached state, and the contained articles can be effectively protected from an external impact, and there is no concern that the article accommodation work will be hindered. . Further, since the peripheral edge of each continuous piece is formed on the inclined surface portion inclined at 45 °, when each connecting piece is brought into contact with each inner wall surface of the box, an air chamber is formed between the both, and the sheet material is formed. Combined with the fact that it is made of resin foam with closed cells (closed cell ratio is 65% or more), the heat insulation is further improved, and the joints between the sheet materials mounted inside the box are Can closely fit and reinforce cardboard boxes.

点と相俟って、その実用的価値は極めて多大である。In addition, since the stored article and the food freshness-keeping material such as the cold storage agent and the ethylene absorbent are separated by the cushioning material, it is possible to avoid the frost damage and the deterioration. Furthermore, since this cushioning material can be flattened at all times and has excellent water resistance and metering properties made of a resin foam sheet, it is extremely convenient for storage and transportation, and it is possible to use a vacuum forming method or the like. Combined with the fact that it can be manufactured at low cost, its practical value is extremely large.
