Description

【考案の詳細な説明】 本考案は二軸延伸される合戒樹脂製壜成形用中間素材に
係る。
射出成形された合成樹脂の有底管状の中間素材を、二軸
延伸ブロー底形して得た合威樹脂製肉薄壜は、その二軸
延伸により機械的強度が高く、且つその他の物性もよく
、炭酸飲料等の内圧の増大する液体及びその他種々の液
体の収容が可能である。
ところで、上述のように中間素材を二軸延伸ブロー成形
する場合、中間素材の底部があまり延伸されず、成形後
の肉薄壜の底が厚くなってしまうのが普通であり、この
ように厚くなった底は、機械的強度その他の物性が悪い
。
底が平坦乃至中央部でやや上昇した通常の形状の壜では
、第４図に示すように、管状中間素材１の底部２を球面
状にすると、底の延伸状態がよいとされているが、それ
でも、第５図に示すように、壜Ａの底Ｂに十分な延伸が
得られず、コーナ一部分では、逆に薄くなり過ぎる傾向
となる。
本案は斯る従来の欠点を除去しようとするものである。
以下、第１図乃至第３図に示す実施例について説明する
。
第１図は、本案による管状中間素材の全体を、第２図は
、その底部を拡大して示している。
図示の管状中間素材１は、飽和ポリエステル樹脂の射出
成形により得たものであり、有底管状をなし、その口部
３は二軸延伸させないために完成形状となっている。
而して、その底部２は、内外面共に胴部４とストレート
に連続する球面α、βとしており、特に、外球面βの曲
率中心点０１より内球面αの曲率中心点０２を少し上方
へずらし、従って、底部２の肉厚を中心に向い次第に薄
くなるように形成している。
また、底部２内面においては、中心部２１の小面積を平
坦にしている。
これは、底部２外面の中心部２１に射出成形のゲートを
位置させるためであり、その場合のカツテングによる肉
厚の極端な変化を防止し、且つ強度の低下を阻止するた
めである。
上述の中間素材を口部３以外において二軸延伸ブロー底
形すると、その当初、エアーの吹込によって底部２の最
も肉薄の中心部１１周辺から二軸延伸され、次第に肉厚
の厚いところへと波及する。
その結果、従来あまり延伸されない底部でも胴部と同程
度の延伸倍率に十分延伸させることができ、第３図に示
すように、壜Ａの底Ｂは肉薄の最良の状態となり、機械
的強度その他の物性が向上する。
また、底Ｂのコーナ一部分で薄くなり過ぎることがない
。
本案によれば、底の肉厚を中心に向い次第に薄く形成し
たので、二輪延伸ブロー成形に際して、底の中心部周辺
から延伸が始まり、これが他へと波及するため、底も十
分に肉薄に二輪延伸され、底が良好に肉薄となって機械
的強度その他の物性の向上された壜が得られる。
また、壜の底のコーナ一部分が薄くなり過ぎることもな
い。
加えて、底部２内面において、中心部２１の小面積部分
を平坦にしているので、底部２外面の中心部にゲートを
位置させて射出成形してもカツテングによる肉厚の極端
な変化を防止でき、中心部の強度の低下を阻止でき、底
部２外面の中心部にゲートを位置させた最良の射出成形
が何等の支障もなく行えて、歩留を向上できる。
しかも、底を十分延伸させるための何等の装置も必要な
く、且つ材料が低減され、頗る経済的である。
