Description

【発明の詳細な説明】
【０００１】
【発明の属する技術分野】この発明は、ボトルの首部に
吊り具を備えた延伸吹込成形によるボトルに関するもの
である。
【０００２】プリフォームの射出成形時に首部のねじよ
り下側の側面から下方に縦長の把手把を一体形成し、そ
のプリフォームの首部基端から底部を延伸吹込成形によ
り薄肉に形成したボトルの把手とすることは既に公知と
なっている。
【０００３】
【発明が解決しようとする課題】この従来の把手は強度
を持たせるために肉厚であり、またボトルの成形樹脂が
ポリエチレンテレフタレートの場合には、射出成形され
たままなので固さを有するが衝撃強度に劣り、内容物を
充填した状態で棚などから床に落下したときに、把手が
破損することがある。またポリプロピレンの場合には可
撓性を有することから落下により破損することはない
が、把手としての固さに問題があり、ポリエチレン等に
より別個に成形した把手を取り付けるようにしている。
【０００４】この発明は、上記従来の課題を解決するた
めに考えられたものであって、その目的は、ボトル首部
の下側に偏平で横長の折曲自在な吊り具を一体に設ける
ことにより、比較的大型のボトルであっても吊り持ちし
易い新たな構成の延伸吹込成形による吊り具付きボトル
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
は、プリフォームの射出成形時に、首部のねじより下側
に形成したサポートリングの片側面に偏平で側方に長い
吊り具を一体形成し、その吊り具より下位の首部基端か
ら底部を延伸吹込成形により薄肉に形成したポリエチレ
ンテレフタレートによるボトルであって、上記吊り具
を、上記サポートリングに一体形成した横幅の広い接続
片と、接続片の自由端に該接続片よりも幅広に形成した
環状の指掛けとから構成し、その接続片の途中の肉厚を
幅方向に形成した狭窄部により薄減して、指掛け側を狭
窄部から上下に折曲可能となすとともに、該狭窄部によ
り樹脂の分子配向を行ってなる、というものである。
【０００６】また上記吊り具によりボトルを支持して注
ぎ易いように、吊り具と反対側のボトル底部に指掛け用
の切欠部を有することを特徴とするものでもある。
【０００７】上記ポリエチレンテレフタレートによるボ
トルでは、吊り具が射出成形されたままであっても、狭
窄部による樹脂の分子配向によって、その狭窄部より指
掛け側が可撓性を有するようになり、これにより曲げ強
度及び衝撃強度が増して薄肉でありながら欠け難いもの
となる。
【０００８】
【発明の実施の形態】図中１はポリエチレンテレフタレ
ートによるボトルで、射出成形されたままの首部２の基
端から胴部３及び底部４を延伸吹込成形により薄肉に形
成したものからなる。
【０００９】５は吊り具で、首部２のねじより下側に形
成したサポートリング６の片側面に、偏平で側方に長く
一体に突出形成されている。この吊り具５は、サポート
リング６に一体形成した横幅の広い接続片５１と、接続
片５１の自由端に該接続片５１よりも幅広に形成した環
状の指掛け５２とから構成されている。また指掛け５２
の面内に形成された指先挿入穴５３の周縁は、上下突出
した凸縁５４により補強されているとともに、掛け止め
た指先に負担がかからないようにしてある。
【００１０】上記接続片５１は、途中の肉厚が幅方向に
形成した狭窄部５５により薄減されており、その狭窄部
