本考案はプラスチック発泡線状体からなる包装用発泡プ
ラスチック緩衝材に関するものである。[Detailed Description of the Invention] The present invention relates to a foamed plastic cushioning material for packaging made of a plastic foam linear body.
一般にプラスチック発泡体は軽量であると共に優れた緩
衝性を有し且つ安価であるため該発泡体を網状にしたも
のが果物等の包装材料として好適なものとされ、現在大
量に使用されているものである。In general, plastic foam is lightweight, has excellent cushioning properties, and is inexpensive, so mesh-like foam is suitable as a packaging material for fruits, etc., and is currently used in large quantities. It is.
而して網状プラスチック発泡体は通常プラスチック例え

泡体にスリットを設けこれに張力を加えながら加熱して
該スリットト部を開口せしめて網状体を得ているもので
ある。Reticulated plastic foam is usually made by extruding a mixture of plastic, such as polyethylene, mixed with a blowing agent into a reticulated shape using a special die, or by creating slits in a sheet-shaped foam and applying tension to it. The net-like body is obtained by heating the net while opening the slit portions.
然しなからこのようにして得た網状体における網目の占
める面積は、発泡体の面積に対し、２〜３倍程度であり
、それ以上にすることは困難であった。However, the area occupied by the mesh in the net-like body thus obtained is about 2 to 3 times the area of the foam, and it has been difficult to increase the area more than that.
又網状体は十分な緩衝性を有せず、これの改良が要望さ
れていたものであった。Furthermore, the net-like body does not have sufficient cushioning properties, and there has been a demand for improvement in this.
本考案はかかる要望に応じ鋭意研究を行った結果優れた
緩衝性を有する簾状発泡プラスチック緩衝材を見出した
ものである。The present invention was created by conducting extensive research in response to such requests, and as a result of which a screen-shaped foamed plastic cushioning material with excellent cushioning properties was discovered.
即ち本考案は断面円形状又はこれに類似した形状を有す
るプラスチック発泡線状体を蛇行させて簾状体に形成し
たものである。That is, in the present invention, a plastic foam linear body having a circular cross section or a similar shape is meandered to form a screen-like body.
本考案を図面にもとづき詳細に説明すると、第１図に示
す如く、直径３〜２５ｍｍ好ましくは５〜１５ｍｍのプ
ラスチック発泡線状体例えば密度０．１ｇ ／ｃｃ以下
の架橋プラスチック発泡体１をダイスから押出しつつ、
その溶融点以上の温度においてこれを適宜の間隔例えば
５〜２５ｍｍを設けて蛇行状２．２’、２“・・・・・
・に折曲げ、冷却することにより所望の譲状に形成し得
るものである。To explain the present invention in detail based on the drawings, as shown in Fig. 1, a plastic foam linear body 1 having a diameter of 3 to 25 mm, preferably 5 to 15 mm, for example, a crosslinked plastic foam 1 having a density of 0.1 g/cc or less is produced from a die. While extruding
At a temperature above its melting point, it is formed into a serpentine shape 2.2', 2"...
- It can be formed into a desired yield shape by bending and cooling.
又本考案緩衝材において発泡体１は第２図に示す如く内
部がよく発泡したプラスチック３の外側に高密度の発泡
体或は無発泡のシース４が被覆されているものを使用す
ることもある。In the cushioning material of the present invention, the foam 1 may be a plastic 3 whose interior is well-foamed and covered with a high-density foam or non-foamed sheath 4 as shown in Fig. 2. .
又パイプ状の発泡体も使用できる。A pipe-shaped foam can also be used.
このように本考案緩衝材は平板状を呈するため特に開口
の狭く奥行の深い間隙部の詰物として有効である。As described above, since the cushioning material of the present invention has a flat plate shape, it is particularly effective as a filler for narrow and deep gaps.
又、その折曲部を自由に調整することにより発泡体相互
の間隔を如何ようにすることができ、適用せんとする製
品に応じた簾状体を容易にうろことが出来る。In addition, by freely adjusting the bent portions, the spacing between the foam bodies can be set in any desired manner, and it is possible to easily form a screen-like body according to the product to which it is applied.
例えば機械的強度に優れたものを得んとする場合には、
その間隔を狭くすればよく、材料費をより安価にする場
合には該間隔を広くすればよい。For example, if you want to obtain something with excellent mechanical strength,
The interval may be narrowed, and if the material cost is to be lowered, the interval may be widened.
又本考案緩衝材は断面円形状の発泡体からなるため表面
が湾曲し発泡体シートにスリットを入れてつくる断面平
滑状発泡体からなる緩衝材に比して優れた緩衝性を有す
るものである。In addition, since the cushioning material of the present invention is made of a foam with a circular cross section, the surface is curved, and it has superior cushioning properties compared to a cushioning material made of a foam with a smooth cross section, which is made by cutting slits in a foam sheet. .
又本考案緩衝材は第３図に示す如く、その折曲部の開口
端部を熱融着５，５′することにより形状保持性を著し
く向上せしめることが出来る。Further, as shown in FIG. 3, the cushioning material of the present invention can significantly improve its shape retention by heat-sealing the open ends of the bent portions 5, 5'.
なお本考案緩衝材を果物その他の包装材料として使用す
る場合には、該緩衝材を手で延伸しその内部に適応面を
装着せしめればよい。When the cushioning material of the present invention is used as a packaging material for fruits or other items, the cushioning material may be stretched by hand and an adaptable surface may be attached inside the cushioning material.
以上詳述した如く本考案緩衝材によれば簡単な操作によ
り所望の大きさの網目を有する簾状体をうるため果物そ
の他の包装材料に極めて有用なものである。As described in detail above, the cushioning material of the present invention is extremely useful for packaging materials for fruits and other fruits because it can produce a screen-like structure having a mesh of a desired size by a simple operation.
