【発明の詳細な説明】 本発明はエーロゾル容器の改良に関し、特に製
品を散布用ガス（推進剤ガス）から隔離して保持
する為の製品袋を有する型のエーロゾル容器に関
する。
通常のエーロゾル容器に於ては、その上端に上
端カール部により形成された25.4mm直径の開口が
設けられ、この開口中に通常の型の散布弁の弁カ
ツプが取付けられるが、別に作られた製品袋が用
いられる場合には、上記弁カツプを上記袋に対し
てシールすることが必要になる。しかし上記袋の
直径が38.1mm程の大きさであるのに対して上記開
口の直径は25.4mmであるに過ぎないから、上記開
口中に通される袋の部分を「ひだ寄せ」する、即
ち、多数のひだを有する形に縮めることを要する
のは明らかであるが、この様なひだ寄せは不整で
あり、よつて、弁カツプと上端カール部との間に
ある袋の部分の厚さは一倍乃至三倍の間に変化
し、この結果、上端カール部または弁カツプに対
する袋のシールが極めて不確実になる。
本発明に於ては、袋が作られているプラスチツ
ク材料の容易な可成形性が利用される。即ち、上
端カール部と弁カツプとの間に置かれる袋の部分
を、可流動にして可接合な温度に加熱することに
より、この部分が実質的に均等な厚さを有する一
体の層にされる。
さらに本発明に於ては、上端カール部が成形型
の一方の型面として用いられ、弁カツプが他方の
型面として用いられて、上端カール部と弁カツプ
との間に置かれたひだ寄せされた袋の部分に圧力
が加えられる。
またさらに、弁カツプは熱伝達手段として用い
られ、この際弁カツプが、上端カール部中に置か
れる前に加熱されるか、または弁カツプが上端カ
ール中に置かれた後に上記カツプに加熱器が作用

以下、添付図面に従つて本発明の実施例を説明
する。
第１図は、通常のエーロゾル容器１０を示し、
容器１０は、缶（容器体）１１及び袋１２を有す
る。
缶１１は、通常の構造であり得るが、図示に於
ては、三体構造であり、本体１３、底端板１４及
び上端板１５を有し、上端板１５は通常のドーム
形をなし、上方及び外方に曲げられた上端カール
部１７により形成された開口１６を有する。
上記缶１１は約68.2mm程度の直径を有し、開口
１６は25.4mmの直径を有し、袋１２は、本体１３
中に一杯になる如き直径を必ずしも有しないが、
第１図に示す如く、25.4mm以上の直径を必らず有
する。従つて、袋１２の上端部が開口１６中を通
過し得る様にする為には、上記上端部を、第１及
び４図に示す如く、「ひだ寄せ」することが必要
である。
袋１２は適当なプラスチツク材料から作られ、
プラスチツクフイルムの積層（ラミネーシヨン）
からも作られ得る。上記ひだ寄せは行わざるを得
ず、この結果、袋１２のひだ寄せされた部分は、
第４図に示す如く、場所により一倍乃至三倍の厚
さになる。
第２図は通常の散布弁の弁カツプ１８を示し、
弁カツプ１８は底２０、円筒形の本体壁２１及び
フランジ（カール部）２２を有し、本体壁２１
は、開口１６中を通る袋１２を介して開口１６中
に密に嵌合する直径を有する。弁カツプ１８は袋
１２の上端部を容器のカール部１７に対して堅く
押付けるのであるが、それにも拘らず、カール部
１７と袋１２との間及び、弁カツプ１８と袋１２
との間に漏洩通路が残されることは明らかであ
る。
袋１２は、積層フイルム製である場合に於て
も、サーモプラスチツク材料で作られているか
ら、加熱されると、自己接合し得るばかりでなく
容易に成形され得る状態になる。従つて、本発明
に於ては、袋１２のひだ寄せされた部分が弁カツ
プ１８と上端カール部１７との間に於て、上記上
端カール部１７と弁カツプ１８とを成形型の二部
分として用いて成形されるが、この際、プラスチ
ツク材料を容易に流動し得る（即ち、成形され得
る）ばかりでなく、自己接合し得る既知の温度に
加熱することが必要とされる。
上記袋の所要の加熱は、弁カツプ１８を加熱す
ることにより行われ得る。第２図中には、弁カツ
プを開口１６中に挿入する前に上記カツプを加熱
する為の加熱手段２３が示されている。図示に於
ては、上記加熱手段は火焔型であるが、誘導加熱
を始めとする他の通常の型の加熱手段も用いられ
得る。
さて第６図には弁カツプ１８とゝもに加熱器２
４が示され、加熱器２４は伝熱体２５の形に作ら
れ、伝熱体２５は弁カツプ１８内に坐してフラン
ジ２２と密接し得る形を有する。図示の加熱器２
４は、電気抵抗加熱体２６を有するが、他の型の
加熱体も用いられ得る。
さて第５図に示す如く、上端カール部１７と弁
カツプ１８との間に置かれた袋１２のひだ寄せさ
れた部分に適当な成形及び熱が加えられると、袋
の上記部分は、流動及び自己接合し、よつて、周
辺全体にわたつて実質的に同じ厚さを有する均等
な一体構造の形になる。袋１２のこの成形及び接
合された部分は、２７として示され、容器体１１
及び弁カツプ１８に対して必要なシールを与える
ばかりでなく、弁カツプと袋との間または袋と上
端カール部との間に何らのシール剤を用いる必要
も無くする役をする。
この様にカール部１７と弁カツプ１８とを成形
型の二つの部分として用い、袋１２の上部を可成
形及び可接合温度に加熱することのみにより、袋
の材料が均等に分布されると同時に、弁カツプと
カール部との間に適当なシール層が形成され得

弁カツプがカール部上に完全に置かれ、袋の上
部の成形が行われた後に、弁カツプは、その本体
壁２１を半径方向外方に膨張して、成形された袋
