Abstract
【解決手段】本発明の密封容器の製造方法は、レーザー溶接法によって、内容物を充填した容器胴体と該容器胴体の口部に装着された蓋とを溶着して気密状態とした密封容器の製造方法において、前記容器胴体の口部に予熱された前記蓋を載せた状態で、前記容器胴体をレーザー照射領域に入れる配置工程と、前記蓋と前記容器胴体との溶着予定箇所に対してレーザー光を照射して、前記蓋と前記容器胴体とを溶着し、容器の密封を行なう溶着工程を有することを特徴とする。
【選択図】図2
Description
サンプルNo.1,2,3,4では、専用に作製したPETボトル胴体及びPET製の蓋を使用した。また、蓋とボトル胴体との溶着予定箇所の蓋側に、市販の808nmの吸光度が約60%の黒色インクを塗布した。サンプルNo.1では蓋を予熱せず、蓋温度は15℃であった。サンプルNo.2,3,4では、蓋温度を30℃、50℃、60℃に予熱した。そして、容器を自転させながら、容器の側面から溶着予定箇所に向けた0.8J/mm2のレーザー照射によって溶接を行い、密封容器を作製した。
サンプルNo.5,6,7では、市販の200mlスチール缶胴体と専用に製作したPET製の蓋を使用した。また、蓋と缶胴体との溶着予定箇所の蓋側に、熱可塑性のシール剤(90℃以上で粘着性発現)を塗布した。サンプルNo.5では蓋を予熱せず、蓋温度は15℃であった。サンプルNo.6では、蓋を缶胴体の口部に載せた後、蓋と缶胴体の全体を温風で加熱して蓋を60℃に予熱した。サンプルNo.7では、蓋を缶胴体の口部に載せた後、蓋を温風で加熱して蓋を60℃に予熱した。そして、容器を自転させながら、容器の側面から溶着予定箇所に向けた0.8J/mm2のレーザー照射によって溶接を行い、密封容器を作製した。
作製した密封容器の底に孔を設け、その孔から0.15MPaの圧縮空気を注入し、蓋のシール性が維持されるか否かで密封性の有無を評価した。各10個のサンプルのうちシール性が全て維持された場合を密封性ありとし、各10個のサンプルのうち1個でもシール性が維持されなかった場合を密封性なしとした。
(サンプルa)
PETボトル胴体の口部に、直径27mm厚さ1mmのPET板を、口部の端部とPET板の表面が重なるように置いた。次に、そのPET板の上に、幅20mm厚さ0.35mmの短冊形のPETシートIIを、PET板の表面とPETシートIIの表面が重なるように置いた。なお、PETシートIIは、PETボトル胴体に相当する。次に、幅20mm厚さ0.35mmの短冊形のPETシートIの表面に、黒色インクを幅1mm長さ10mmで直線状に塗布した。次に、このPETシートIを、先のPETシートIIの上に、PETシートIIの表面とPETシートIの黒色インクが塗布された側の表面とが重なるように置いた。なお、PETシートIは、PET製の蓋に相当する。次に、PETボトル胴体の上方からPET板全体を包含する領域に向けた0.8J/mm2のレーザー照射によって溶接を行い、サンプルaの溶接シートを作製した。ここで、黒色インクを塗布した場所が溶着箇所となった。
(サンプルb)
インクを塗布したPETシートIをPETシートIIの上に置く前に、温風で加熱して30℃に予熱した以外はサンプルaと同様の方法でサンプルbの溶接シートを作製した。
(サンプルc)
PETシートIを予熱する温度を、30℃から50℃に変更した以外は、サンプルbと同様の方法でサンプルcの溶接シートを作製した。
(サンプルd)
PETシートIを予熱する温度を、30℃から60℃に変更した以外は、サンプルbと同様の方法でサンプルdの溶接シートを作製した。
(サンプルe)
PETシートIIを幅10mmの短冊形のスチール缶片に変更し、黒色インクをシール剤に変更した以外はサンプルаと同様の方法でサンプルeの溶接シートを作製した。ここで、シール剤を塗布した場所が溶着箇所となった。なお、スチール缶片は、スチール缶胴体に相当する。
(サンプルf)
シール剤を塗布したPETシートIをスチール缶片の上に置いた後に、上方からPETシートIに温風を当てて、PETシートIを加熱して60℃に予熱した以外はサンプルeと同様の方法でサンプルfの溶接シートを作製した。
作製した溶接シートについて、島津製作所製オートグラフAG−10kNDで引張試験を行った。溶接シートの一方であるPETシートIと他方であるPETシートII又はスチール缶片を、シートの主面上で、黒色インク又はシール剤を塗布した直線ラインに対して垂直方向に互いに反対方向に引っ張り、剪断強度を測定し、予熱が有意に機能するか検証した。
