Abstract
本発明の目的は、レーザー溶接をはじめ、熱溶融によって密封をする飲料・食品用容器等の密封型容器について、口部と蓋の構造を工夫することにより、高い夾雑物適性を付与することである。そして密封性を高く、また容器胴体と蓋との接合強度を高くすることを目的とする。
【解決手段】
本発明に係る密封容器は、口部を有する容器胴体と、前記口部を閉じたときに自己にひずみを生じさせ、該ひずみを緩和する応力によって前記容器胴体に対して加圧状態の密着部分を生じさせ、且つ、該密着部分が封じ目となる可塑性材料で形成された蓋とを有し、前記密着部分が熱融着されていることを特徴とする。
【選択図】 図1
Description
図1に第1実施形態に係る密封容器の概略図を示した。(a)は、容器胴体に口部を装着したときの口部付近の縦断面概略図、(b)はA方向から見た外観概観図、(c)はB方向から見た蓋の斜視概観図である。第1実施形態に係る密封容器100では、容器胴体1の口部9の外壁に口部9の縁5と平行に環状のリブ6を設け、蓋3の縁7にリブ6と密着部分4を形成する環状のリング8を設け、口部9の外壁のうち、リブ6よりも口部の縁5側に環状の凸起2を設け、蓋3の内壁のうち、蓋3の縁7に設けたリング8との間隔が、口部9に設けた環状の凸起2とリブ6との間隔よりもわずかに長い間隔となる箇所に、環状の凹陥11を設けている。そして、リブ6とリング8との密着部分4が熱融着されている。
図2に第2実施形態に係る密封容器の概略図を示した。容器胴体に口部を装着したときの口部付近の縦断面概略図を示している。第2形態に係る密封容器200では、容器胴体1の口部9の外壁に口部の縁5と平行に環状のリブ6を設け、蓋3の縁7にリブ6と密着部分4を形成する環状のリング8を設け、口部9の外壁のうち、リブ6よりも口部9の縁5側に環状の凹陥15を設け、蓋3の内壁のうち、蓋3の縁7に設けたリング8との間隔が、口部9に設けた環状の凹陥15とリブ6との間隔よりもわずかに長い間隔となる箇所に、環状の凸起16を設けている。そして、リブ6とリング8との密着部分4が熱融着されている。第2実施形態と第1実施形態とは、凸起と凹陥の関係が逆となっている点の差異がある。
図3に第3実施形態に係る密封容器の概略図を示した。容器胴体に口部を装着したときの口部付近の縦断面概略図を示している。第3実施形態に係る密封容器300では、蓋3の内壁面と口部9の縁5との当接面19を設け、口部9の外壁に口部9の縁5と平行に環状の凹陥17を設けている。また、蓋3の内壁面には、環状の凸起18を設けている。さらに、蓋3の内壁のうち、当接面19との間隔が、口部9の縁5と口部9に設けた環状の凹陥17との間隔よりも、わずかに短い間隔となる箇所に、環状の凸起18を設けている。そして、容器胴体1の外壁に設けた環状の凹陥17と、蓋3の内壁に設けた環状の18凸起との密着部分4が熱融着されている。
図4に第4実施形態に係る密封容器の概略図を示した。容器胴体に口部を装着したときの口部付近の縦断面概略図を示している。第4実施形態に係る密封容器400では、蓋3が容器胴体1の口部9の縁5の表裏面を挟む湾曲部20を有し、湾曲部20と容器胴体1との密着部分4が熱融着されている。
