接着方法に関し、発泡体とフイルムとの材質の組
合せによつて熱接着が不可能なものに対しても、
接着剤等を用いず容易に接着できる方法を提供し

従来、熱可塑性樹脂発泡体とフイルムを接着す
るには、熱接着により発泡体とフイルムとを直接
融着一体化する方法が用いられており、能率的で
接着強度も大きく、接着剤を使用しない為に衛生
的にも優れるなど好適な方法として広く採用され
ている。
ところが、発泡体とフイルムの材質によつて
は、熱接着が困難であつたり全く下可能な場合が
ある。例えば、ポリスチレン発泡体に対してポリ
プロピレンフイルムやポリエチレンフイルムを熱
接着することは従来不可能とされており、これら
熱接着困難な素材の組合せの場合には、接着剤を
介在させたり、熱接着可能な素材との積層フイル
ムとして発泡体に熱接着するなど、非常に面倒で
改善が望まれていた。
そこでこの発明方法においては、上記接着剤等
は全く使用せず、発泡体とフイルムとを直接容易
に接着できる方法を開発したものであり、その方
法は熱可塑性樹脂発泡体にフイルムを重ね、フイ
ルム側から多数のピン状或いは偏平な薄板状をな
す突起状加熱片を押し当て、該加熱片にて発泡体
に加熱片形状に沿う凹部を溶融形成すると同時に
該凹部内にフイルムを押入して上記凹部の内面形
状に沿つた押入部を形成し、該押入部と凹部とが
密着係合することによつて、発泡体とフイルムと
が接合されるようにしたことを特徴としている。
次いでこの発明の実施態様について図を参照し
ながら以下に例示する。
１は発泡ポリスチレン等の熱可塑性樹脂発泡体
であり、２はポリプロピレン等のフイルムであつ
て、両者は通常の熱接着方法では接着が困難な素
材の組合せである。
３が突起状加熱片であり、先端がピン状をなし
ていて、多数の加熱片３が背後の基盤３０等に取
付けてあり、多数の加熱片３が同時に発泡体１と
フイルム２の上面に降下できるようにしてあり、
また各加熱片３はヒータ等にて加熱されているも
のとする。
上記のごとき加熱片３を使用して発泡体１とフ
イルム２とを接着するには、先ず発泡体１の上面
にフイルム２を重ねて載置しておく（第１図参
照）。
次いで基盤３０の下面に突出する多数の加熱片
３０を降下させてフイルム２の上面に押し当て、
フイルム２を通して発泡体１を押圧することによ
つて発泡体１を加熱溶融せしめ、発泡体１に加熱
片３の突起形状に沿う凹部１０を陥入形成する。
このとき発泡体１上面のフイルム２が突起状加熱
片３０にて上記凹部１０内へ押し込まれ、フイル
ム２の当該個所に加熱片３形状即ち凹部１０の内
面形状に沿つた押入部２０が形成され、この押入
部２０と凹部１０とが密着係合することによつて
両者間に接合力が生じ、発泡体１とフイルム２が
接着されることになる（第２図参照）。
従つて、発泡体１とフイルム２とは加熱片３に
て加熱されて互いに溶融接着するのではなく、発
泡体１に形成される凹部１０とフイルム２に形成
される押入部２０とによる一種の強制嵌合力によ
つて互いに接合されるのである。
なお上記実施例のごとく多数の加熱片３を板状
の基盤３０に取付け、全体を一斉に上下動させる
方法のほか、多数の加熱片３を回転ローラ３１の
外周に取付け、該ローラーを重ね合せた発泡体１
とフイルム２の上面で回転させることにより、多
数の加熱片３を順次フイルム２上に押し当て連続
的に発泡体１とフイルム２を接着していくように
すれば、非常に能率的に作業ができ好適である
（第５図参照）。
また加熱片３はフイルム２および発泡体１に直
角に押し当てるだけでなく、加熱片３を斜め方向
からフイルム２および発泡体１に押し当てるよう
にすれば、フイルム２の押入部２０と発泡体１の
凹部１０との嵌合力が一層強く抜脱し難くなり、
接着力の向上を図れ好適である（第６図参照）。
加熱片３の形状としても、単なるピン状のもの
のほか、扁平な薄板状のものを使用すれば、第７
図に示す細長い溝状の凹部１０あるいは押入部２
０となり、さらに上記薄板状の加熱片３が「く」
の字状に曲がつたものを使用すれば、第８図に示
す「く」の字溝状の凹部１０等が形成される。
上記のごとき接着方法を用いるのに好適な発泡
体１とフイルム２の素材としては、互いに熱接着
が困難な素材の組合せが好ましく、例えばポリス
チレン発泡体に対してポリプロピレンフイルム、
ポリエチレンフイルムあるいはポリエステルフイ
ルムなどを接着する場合が挙げられる。
なお加熱片３をフイルム２上面より発泡体１に
押し当てるので、フイルム２の耐熱温度は発泡体
１より高いほうが望ましく、加熱片３の加熱温度
は発泡体１の軟化温度程度にしておくのが好適な
実施であり、例えポリスチレン発泡体の場合100
℃±20゜程度である。
以上のごとく構成されたこの発明方法によれ

当てて形成する発泡体１の凹部１０とフイルム２
の押入部２０とによる一種の嵌合力によつて両者

溶融接着できない材質からなる発泡体１とフイル
ム２との組合せに対しても、容易に接着すること
ができる。しかも接着剤や溶剤を使用するもので
はないから、作業性も良く、食品包装容器等に用

特に作業工程としては、加熱片３の押し当てだ
