Description
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。
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。
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。

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。

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。
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。
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。
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。
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。
形成した狭窄部55により薄減されており、その狭窄部
55から指掛け52を上下に折曲できるようにしてあ
る。また狭窄部55により射出成形時に樹脂の分子配向
が生じて指掛け側が可撓性を有するようにしてある。
射出成形される。成形は首部12のサポートリング16
に接続して、吊り具5の偏平なキャビティ15を首部1
2の成形型31と、胴部13及び底部14の成形型32
のパーティング面に形成し、サポートリング16から溶
融樹脂を射出充填することで容易に行いうる。
5に充填された樹脂は、キャビティの上下面から突出形
成した突条により流量が制限された通路、即ちキャビテ
ィ内の狭窄部15aにより絞られて指掛け側に強制的に
流入するようになり、その際に樹脂の分子が樹脂の流れ
方向に配向される。
ル1がポリエチレンテレフタレートによるものであって

肉の狭窄部55が疲労により千切れることはない。な
お、狭窄部55を設けずに成形したものにあっては、肉
厚が1.5mm程度であっても固く折り曲げが困難であ
