Description
このように鋭利な形状で凝固した排斥樹脂は、振動や衝撃が加えられると脱落しやすいことから、溶着部を備えた製品の使用環境や輸送環境を汚損する問題がある。また、電子部品等の精密部品を収納した内部空間を備えた製品の場合には、内部に脱落した排斥樹脂の衝突によって、精密部品が損傷される問題がある。また脱落しなくても、鋭利な部分が製品の外部に露出することは、美観を損ねる問題がある。
図1は本発明の実施の形態1である樹脂溶着体を示す部分断面図である。樹脂溶着体として有底円筒状のケースと蓋体で形成される密封容器1を例にして説明する。密封容器1の蓋体2はレーザ光に対して透過性を有する樹脂部品であり、有底円筒状のケース3は前記レーザ光に対して吸収性を有する樹脂部品である。両樹脂部品が接触して形成された接触部21が溶着されて接合部4を形成している。接合部4は、ケース3に設けられた環状のリブ(第2環状突起)5の先端部と蓋体2との間に存在し、溶着時にレーザ加熱によって一旦溶融し、再度凝固した箇所である。リブ5は、ケース3の外周に沿って内周側に環状に設けられており、その外周側には蓋体2とケース3の最外周の第1環状突起22との嵌合により形成された閉空間6が設けられている。
当然ながら、実施の形態として挙げた密閉容器1は本発明の樹脂溶着体の一例に過ぎない。接合部4は環状である必要はなく、必要に応じて、線状あるいは点状など任意の形状が選択できる。また、閉空間6の形状も接合部4(又は接触部21)の形状に合わせて任意に選択することができる。ただし、閉空間6の内壁の一部に接触部21の一端部又は接合部4の端部が露出している必要がある。
図4は実施の形態2である樹脂溶着体を示す部分断面図である。実施の形態1との相違点は、接触部21から排斥された樹脂を収納する閉空間を有していないことである。リブ(第2環状突起)5の内周側には、蓋体2に設けられた第4環状突起10が嵌合されているため、接触部21からの排斥樹脂7は、リブ5の外周側にはみ出し、閉空間が設けられていないため、ケース3の外周面に露出している。この排斥樹脂7の露出面は全部または一部が所定の形状に成形されている。なお、24は接触部21の外周側の端部に面してケース3に形成された排斥樹脂7の溜め部である。
このように排斥された溶融樹脂は鋭利ではない所定の形状に成形されている為、振動や衝撃に対する脱落の危険が低減できる。ここで、概閉空間14の容積は排斥樹脂7の体積と同程度に設定することが望ましい。概閉空間14の容積が排斥樹脂7の体積よりも過大であれば、排斥樹脂7は概閉空間14の中で自由に成長でき、鋭利な形状への成長を抑制する効果が減少する。一方、過小であれば鋳型A1と蓋体2あるいはケース3との間に存在するわずかな隙間に排斥樹脂7が侵入し、結果として鋭利な形状に至る。
