【発明の詳細な説明】
【０００１】
【発明の属する技術分野】この発明は、目薬や化粧品等
の小型偏平容器の製造に際して射出成形されたプリフォ
ームと、そのプリフォームから製造された細口の小型偏
平容器に関するものである。
【０００２】
【発明が解決しようとする課題】射出成形したプリフォ
ームを延伸又は延伸無しでブロー成形して、胴部が薄肉
の偏平容器を製造する場合には、プリフォームの胴部の
前後面側と左右面側との肉厚を加減し、それにより胴部
の熱容量に差を持たせている。この肉厚の加減には胴部
外側を長円形や平行面等に形成したり、或いは射出コア
に偏平コアを採用して、胴部の内側対向面を平行面に形
成するなどして行われるが、肉厚設定の容易性から、そ
の殆どは偏平コアにより胴部肉厚の加減を行っている。
【０００３】しかしながら、目薬、化粧品等の細口の小
型偏平容器では、プリフォームの内径も小さく制限され
るので、そこに採用される射出コアも必然的に小径のも
のとなり、そのような射出コアの両側面を平らに形成す
ることは、内部に冷却路が二重に設けられていることか
ら極めて難しく、このため偏平コアによりプリフォーム
の胴部肉厚を加減して製造できる小型偏平容器には限界
があった。
【０００４】この発明は、上記事情から考えられたもの
であって、その目的は、偏平コアによる肉厚加減の限界
を、ステップアップ成形した胴部の外側を減肉成形し
て、偏平成形に不可欠な肉厚差（熱容量差）を持たせる
ことにより解決でき、またブロー成形による胴部の偏平
化に際しても偏肉が生じ難く、薄肉で肉厚分布が整った
細口の小型偏平容器を製造することができる新たなプリ
フォームと、そのプリフォームにより製造された小型偏
平容器とを提供することにある。
【０００５】
【課題を解決するための手段】上記目的によるこの発明
の小型偏平容器用プリフォームは、内径が真円で小さく
制限された小型偏平容器用のプリフォームであって、ネ
ック部と胴部との境から胴部をネック部よりも大径にス
テップアウト形成し、そのステップアウトの下側から胴
部外側を長円形等に減肉形成して、胴部の前後面側と左
右面側との肉厚に差を持たせるとともに、ステップアウ
ト部をネック部下側に円板状に残設してなる、というも
のである。
【０００６】またこの発明の小型偏平容器は、上記小型
偏平容器用プリフォームをブロー成形して製造された細
口の小型偏平容器であって、ネック部下側に円板状のス
テップアウト部を有し、そのステップアウト部の下縁に
連続して胴部を薄肉に偏平形成してなる、というもので
ある。
【０００７】
【発明の実施の形態】図１は、この発明の小型偏平容器
用プリフォームの１実施形態を示すもので、プリフォー
ム１は通常容器のプリフォームと同様に、ポリエチレン
テレフタレート（ＰＥＴ）などのポリエステル樹脂、ポ
リプロピレン（ＰＰ）、ポリカーボネート（ＰＣ）、ポ
リエチレン（ＰＥ）などにより、ネック部１１と胴部１
２とを射出成形により一体形成した有底のものからな
る。
【０００８】このプリフォーム１は、全体の高さが３０
mmで、その高さの約１／３を占めるネック部１１のねじ
山１１ａを含む外径は８．８mm、内径は射出コアの抜き
勾配の設定のために、ネック部１１の開口から底部１３
に向けて若干縮径されているが真円で、その直径は開口
で４．５mmに小さく制限されたものからなる。
【０００９】また胴部１２は、ネック部１１との境から
ネック部１１よりも大径（１４．２mm）にステップアウ
トして厚肉形成され、そのステップアウトの下側から胴
部１２の外側を長円形に減肉形成して、真円の内側との
関連により胴部１２の前後面側１２ａを厚肉（２．６m
m）に左右面側１２ｂを徐々に薄肉（２．０mm）に形成
してある。また胴部外側の減肉形成によりネック部１１
下側にステップアウト部１４が円板状に残設されてい
る。
【００１０】このようなプリフォーム１では、ステップ
アウトにより胴部１２の肉厚を自由に設定でき、その設
定時の肉厚を胴部の最大肉厚として、胴部外側を長円形
又は図は省略するが平行面に形成することで、前後面側
１２ａと左右面側１２ｂとの肉厚に差を持たせることが
できるため、胴部１２の肉厚加減がネック部１１の投影
面内に制限されず、ネック部１１の外径を上回る範囲で
の肉厚設定が可能となるので、内径が小さく制限された
細口の小型偏平容器でも容易に成形することができる。
【００１１】図２は、上記プリフォーム１から製造され
た目薬用の細口の小型偏平容器であって、この小型偏平
容器２は、ねじ山２１ａを外周囲に有するネック部２１
と、そのネック部２１の下側に一体成形した円板状のス
テップアウト部２４と、そのステップアウト部２４の下
縁から前後面側２２ａ及び底部２３をフラット面に、左
右面側２２ｂを円弧状に延伸ブローして偏平に形成した
薄肉の胴部２２とからなる。
【００１２】このような小型偏平容器２は、射出成形後
の高熱離型によりステップアウト部１４から胴部１２が
加熱された状態にある上記プリフォーム１を、ブロー金
型３の偏平キャビティ４にセットし、図では省略する
が、通常容器の延伸ブロー成形と同様にネック部１１を
保持して、胴部１２を延伸ロッドとエアブローとによ
り、偏平キャビティ一杯に延伸ブローすることで容易に
成形することができる。
【００１３】この際、プリフォーム１は、図３に示すよ
うに、厚肉に形成された胴部１２の前後面側１２ａ，１
２ａが、偏平キャビティ４の幅狭の方の型面に向けて位
置するようセットし、これにより薄肉の左右面側１２
ｂ，１２ｂを、図４に示すように、幅広の方の型面に臨
ませるのが好ましい。これは膨張倍率の差から前後面側
１２ａ，１２ａが先に型面に接して冷却されても、厚肉
の前後面側１２ａ，１２ａの方が熱容量が大きく、型面
に接した後も充分な熱量が確保されて左右方向ににも伸
展するからで、これにより薄肉の左右面側１２ｂ，１２
ｂの伸展も抵抗なく行われて、胴部全体が均一薄肉の偏
平胴部に成形されるからである。
【００１４】また胴部１２は、ネック部１１との境に形
成した円板状のステップアウト部１４によって充分な熱
量が確保されていることから、その下縁から周囲に均等
に拡張するようになる。従来の小型偏平容器では、胴部
１２をネック部１１との境から直接に延伸膨張している
ので、その境が曲面に形成されて裾長となりやすく、こ
のためネック部２１と胴部２２との境をくっきりと形成
することが困難であったが、この発明による小型偏平容
器２では、図２に示すように、ネック部２１の立ち上が
りが円形面のステップアウト部２４からとなって形状が
整い、また肩部の仕上がり状態も良好な太鼓形の小型偏
平容器２となる。
