つた。《Prior art and its problems》 Conventionally, this type of cushioning material and cushioning materials have cylindrical mutually independent air chambers, that is,
It is common to have a large number of cushion chambers. However, in such a cushion material, if an excessive load is applied to the cushion chamber from above and below, the wall defining the cushion chamber will break, and the air inside will escape. Therefore, the cushion chamber no longer exists in this part, and this part loses its cushioning properties. Therefore,
When packaging and transporting fragile items using this cushion material, if a large load is applied to a certain part and the cushion chamber in that part is damaged,
There was a risk that the packaged item would be damaged by the load that was then applied again to that part.

る。 The present invention was developed in view of the above-mentioned problems, and its purpose is that even if an excessive load is applied to one cushion chamber and its wall is damaged, the air in that cushion chamber will be drained from the adjacent cushion. To provide a cushion material which has excellent cushioning properties and does not allow air to escape by simply expanding in communication with a chamber.

A sheet having a large number of parallel partition legs between two sheets is integrally formed from a soft synthetic resin, and a plurality of heat sealing lines extending in a direction intersecting the partition legs are attached to the upper and lower sheets. By welding them to each other, a large number of cushion chambers filled with air are formed in each section defined by the upper and lower sheets, the adjacent partition legs, and the seal line, and each cushion chamber is filled with air. The partition leg has a lower breaking strength than the upper and lower sheets, and when an excessive load is applied to each cushion chamber from above and below, the partition leg breaks and the area divided by the seal line is damaged by other adjacent cushion chambers. It is characterized by being in communication with the
《実施例》
以下に本考案の好適な実施例について添付図面
を参照にして説明する。<<Embodiments>> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
本考案の包装用緩衝材１は軟質なポリエチレン
のような合成樹脂から形成され、上下２枚の軟質
合成樹脂製シート２，３の間に多数の平行な仕切
脚４−４が一体的に形成されている。 The packaging cushioning material 1 of the present invention is made of a soft synthetic resin such as polyethylene, and a large number of parallel partition legs 4-4 are integrally formed between two upper and lower soft synthetic resin sheets 2 and 3. has been done.

することはない。 A plurality of heat-sealing lines 5-5 are provided in parallel and at equal intervals in a direction intersecting, preferably perpendicular to, the partition leg 4-4, and the two upper and lower sheets 2 and 3 are integrally welded. are doing. As a result, an airtight cushion chamber 6 is formed in which each section defined by the upper and lower sheets 2, 3, the adjacent partition leg 4-4, and the adjacent seal line 5-5 is filled with air. . In this way, a large number of cushion chambers 6 are arranged side by side between the seal lines 5-5 via the partition legs 4-4. Here, the partition leg 4-4 of each cushion chamber 6 has a lower breaking strength than the upper and lower sheets 2, 3 by making its wall thickness thinner than that of the ventilation sheets 2, 3. The partition leg 4 is made to break when an excessive load is applied to each cushion chamber 6 from above and below. When this partition leg 4 breaks, this broken cushion chamber 6 communicates with the adjacent cushion chamber 6 to become a sealed cushion chamber twice the size, and the air in the broken cushion chamber 6 is dissipated to the outside. There's nothing to do.

直交する方向に施してやる。 In order to mold the above-mentioned cushion material, a molten soft thermoplastic synthetic resin is extruded from a long and narrow ladder-like die, which is formed by connecting a pair of relatively long slits close to each other with a large number of short and small slits. , the two upper and lower sheets 2, 3 and a large number of partition legs 4-4 therebetween are integrally molded at the same time. Next, a plurality of heat-sealing lines 5-5 are applied in a direction perpendicular to the partition legs 4-4 while forcing air between the upper and lower sheets 2 and 3.

ものとなる。 The heat sealing line 5 serves as a folding line when the cushion material 1 is bent. When the sealing line 5 is formed in a direction perpendicular to the partition leg 4, as shown in FIG. The cushion material 1 is suitable for packaging tubular bodies such as fluorescent tubes. Furthermore, if the seal line 5 is formed in a direction diagonal to the partition leg 4, the cushion material 1 becomes suitable for wrapping bulky items such as fruits, as shown in FIG. . Furthermore, if a large number of heat-sealing lines 5 are arranged in a staggered manner in a direction perpendicular to the partition legs, the heat-sealing lines 5 may be It is similar to the first embodiment in that it is easy to bend along the ridgeline, but since the cushion chamber is located in about half of the ridgeline, the ridgeline can be better protected.
