Abstract
Description
内容物を収納した容器本体の開口部に蓋体を溶着するべく、前記蓋体を前記開口部に押し付けるための押圧端部を先端に有するシールヘッドであって、
前記押圧端部の少なくとも一部が、前記開口部の径方向内側と径方向外側との間で断面輪郭の曲率半径が異なる不均等凸部として形成されている点にある。
内容物を収納した容器本体と、シールヘッドによって同容器本体の開口部に溶着された蓋体とを備え、
前記溶着によって前記開口部に形成されたシール溝部の少なくとも一部が、前記開口部の径方向内側と径方向外側との間で断面輪郭の曲率半径が異なる不均等溝部とされている点にある。
(ポーション容器の概略構成)
図1は本発明に係るシールヘッドによって作製されたポーション容器の一例を示しており、この図1のポーション容器1は、液体状などの内容物Cを収納した有底で樹脂製の容器本体2と、同容器本体2の開口部を密閉状に閉じる樹脂製の蓋体9とを備え、容器本体2の少なくとも一部は外力によって容易に変形されるように構成されている。
図2は、上記のポーション容器1と組み合わせて用いることで、ポーション容器1から排出された内容物Cを他の液体Lなどと容易に混合することの可能なボトル10の一例と、ボトル10にセットされたポーション容器1とを示している。
容器支持部13は、円筒部12Aの上方内部空間とボトル本体11の内部空間とを連通させるべく上下に延びた開口部14に向かって次第に低くなる傾斜面13Aを備えている。
図4に示すように、容器本体2の側壁部4は、底面3に向かって次第に縮径化される筒状体によって構成されており、フランジ5の裏面から底面3に向かって延出した基端部4Aと、底面3からフランジ5に向かって延出された先端部4Cと、これら基端部4Aと先端部4Cとを接続する中間部4Bとを備える。
図1及び図6に示すように、容器本体2と蓋体9とを封止している環状シール部6は、全周に亘って、フランジ面5Aの幅の全体が面状に溶着された形態ではなく、フランジ面5Aの幅の一部を占めるライン状に溶着された形態を呈している。
尚、本明細書において島状部とは、蓋体9がフランジ面5Aに対して意図的に部分的に溶着されずに、周囲の溶着された部位の内部に島状に残された部位を指す。
三角シール部6Tは、フランジ面5Aにおける被係合凹部5Bの径方向内側に相当する領域に沿って設けられており、全体として環状シール部6の径方向内側に向かって突出した左右対称な二等辺三角形状を呈している。
他方、二等辺三角形の径方向外側の底辺に相当する1辺は、逆向き環状シール部6Aの両端を連結するように直線状に延びた補助分離シール部6Bとされている。
〈1〉径方向内側の部位が径方向外側の部位に比べて急な角度で底面3向きに窪むシール力不均等溝を、逆向き環状シール部6Aのみでなく補助分離シール部6Bにも適用した形態や、環状シール部6の全周において適用した形態で実施することも可能である。この場合は、シールヘッド30の環状突起31Aにおける該当箇所を、径方向内側の部位が径方向外側の部位よりも小さな曲率半径を有する左右非対称の特殊な断面形状としておくことが必要である。
