本発明は合成樹脂製のチューブ容器に関する。
【０００２】
【従来の技術】
従来、胴部上端から肩部を介して口頸部を起立し、該口頸部にキャップを螺合させ、又胴部下端を板状に挟着させてシールした合成樹脂製チューブ容器が広く用いられている。
【０００３】
【発明が解決しようとする課題】
上記口頸部は胴部に比して著しく小外径であり、又肩部も上部小外径のテーパ状であるため、チューブ容器は容量に比して長くなる欠点があった。
【０００４】
本発明チューブ容器は上記キャップ螺合用口頸部に代えて、胴部上端面をほぼ平板状に低高の頂板で閉塞し、該頂板中央部に設けた注出孔を、肉薄ヒンジを介して頂板に付設した蓋板が有する栓で開閉するよう設けることで、チューブ容器の小外径部分を除去し、もってチューブ容器の容量を変えることなく、その全体長さを短かく形成できるよう設けたものである。
【０００５】
【課題を解決するための手段】
溶融した樹脂をシートに形成し、該シートを円盤状に打抜き、該打抜き円盤をチューブ容器体の胴部形成用スリーブの上端面へ嵌合溶着させて、該スリーブ上端面を閉塞する円盤部分を圧縮成形してチューブ容器体の頭部を形成するサッチャー方式のチューブ容器成形方法により、
上記頭部７を、中心部に注出孔２を有する円形頂板３の外周から係合短筒４を垂下すると共に、該係合短筒下端から外向きフランジ状壁５を介して、フランジ状壁の外縁から上記スリーブ１の上端部内面へ溶着させて接合短筒６を垂下する、ほぼ平板状の低高に形成し、
上記係合短筒４外面へ嵌合させた縦筒部12下端から上記フランジ状壁５上面へ載置させて外方張出し板13を突設したリング状部11と、上記注出孔２へ嵌合させた栓16を頂壁17中央部から、又上記縦筒部12外面へ下端部を嵌合させた短周壁18を頂壁17外周部から、それぞれ垂設して設けた蓋板15とを、張出し板13外縁の一部と短周壁18の下端一部とを肉薄ヒンジ20で連結させて設け、
上記頭部７とリング状部11とを着脱不能に一体的に接合させた。
【０００６】
【発明の実施の形態】
以下図面について説明すると、１はチューブ容器の胴部形成用スリーブで該スリーブの上端は注出孔２付きの頂板３を有する頭部７で閉塞している。該頭部は中心部に注出孔２を有する円形頂板３の外周から係合短筒４を垂下すると共に、該係合短筒下端から外向きフランジ状壁５を介して、上記スリーブの上端内面へ溶着させて接合短筒６を垂下している。
【０００７】
該頭部はいわゆるサッチャー方式（特公昭38-23485号）により形成する。該サッチャー方式を簡単に説明すると、溶融した樹脂をシート状としてこれを円盤状に打抜き、胴部形成用スリーブの上端面へ、該上端面を閉塞させて溶着し、次にその溶着させた円盤部分を圧縮成形してチューブの頭部を形成するものである。
【０００８】
上記頭部とは別に、肉薄ヒンジを介してリング状部11と蓋板15とを一体成形した部材を成形しておき、そのリング状部を既述係合短筒４外面へ嵌合させると共に外向きフランジ状壁５上へ載置させて、超音波接着等して一体的に成形し、蓋板15に設けた栓を注出孔２へ着脱自在に嵌合させる。
【０００９】
リング状部11は、図１と図３とが示すように係合短筒４外面へ嵌合させた縦筒部12下端から、既述外向きフランジ状壁５上面へ載置させて外方張出し板13を突設して形成する。
【００１０】
蓋板15は、注出孔２へ嵌合させた筒状の栓16を頂壁17中央部から、又その頂壁外周部から、既述縦筒部12外面へ下端部を嵌合させて短周壁18を、それぞれ垂設している。
【００１１】

【００１２】
尚スリーブ下端の閉塞は通常行っているようにスリーブ内への収納物充填後、そのスリーブ下端を挟着して板状にシールする。
【００１３】
【発明の効果】
本発明は既述構成とするものであり、チューブ容器のスリーブ上端へ付設する頭部７を、ほぼ平板状の低高に形成したから、又蓋板15も該蓋板の頂壁17下面から垂下する栓16を頭部の頂板に穿設した注出孔２へ嵌合させ、かつ蓋板頂壁の外周から垂下する短周壁18を頭部７の頂板３外周部へ嵌合させたリング状部11の縦筒部12外面へ嵌合させるから、該蓋板頂壁17の位置も低くすることが出来、よって胴部上端から肩部を介して口頸部を起立し、かつ該口頸部へキャップを螺合させる従来例に比べて容量を変えることなく、容器の長さを短かくすることが出来る。
【００１４】
又その頭部７は、注出孔２を有する円形頂板３外周から係合短筒４を垂下すると共に該係合短筒下端から外向きフランジ状壁５を介してスリーブの上端部内面へ溶着させた接合短筒６を垂設して形成するから、肉薄ヒンジ20を介して蓋板15を付設したリング状部11の縦筒部12を上記係合短筒４外面へ嵌合させ、かつその縦筒部下端から突設した外方張出し板13を、外向きフランジ状壁５上面へ載置させた状態で、頭部７とリング状部11とを超音波接着等して一体に接合することが容易であり、更にそのように形成したから、肉薄ヒンジ20を中心とする蓋板15の回動で栓16注出孔２に着脱でき、その開閉蓋が便利である。
