【発明の属する技術分野】
本発明は、弧回動開閉自在でかつ取外し自在な容器の蓋体着脱構造に関するものである。
【０００２】
【従来の技術】
従来、容器の蓋体着脱構造は、容器本体の肩部材の後部にヒンジ部を設け、このヒンジ部に溝付きの鉤状係止部を形成し、蓋体のヒンジピンをこの鉤状係止部の溝内に弧回動自在に枢支していた。しかもこの鉤状係止部の溝内にヒンジピンを導く導通路を鉤状係止部の前方より斜め後部下方に向けて傾斜させているか又は後方より斜め前部下方に向けて傾斜させて、蓋体のヒンジピンをこの導通路に沿わせ取外し自在としていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来のこの種の容器の蓋体着脱構造にあっては、蓋体の取外しが導通路に沿って簡単にできる利点はあったが、蓋体の離脱時のみに限らず蓋体を弧回動に開閉する際に、全く予期せず勝手に蓋体のヒンジピンが導通路に沿って移動し、鉤状係止部の溝内より離脱してしまうという問題点があった。
【０００４】
そこで、本発明は、このような従来の容器の蓋体着脱構造が有していた課題を解決するために、蓋体の弧回動開閉並びに着脱の操作が容易かつ確実に行われると共に簡単な構造にして組立作業も極めて容易に行うことを目的とした容器の蓋体着脱構造を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明の容器の蓋体着脱構造は、ヒンジ部９には、ヒンジピン１１を介して蓋体(７)を弧回動開閉自在に枢支する溝１２付きの鉤状係止部１３と、左、右側壁部１５、１５と、鉤状係止部１３の前面にあってヒンジピン１１の前方離脱を防ぐ前壁部１６とが一体的に設けられ、
鉤状係止部１３と前壁部１６との間が、ヒンジピン１１を鉤状係止部１３の溝１２内に導通する挿通部１４とされ、前壁部１６と、左、右側壁部１５、１５と、鉤状係止部１３の下部後壁部とによって、下端が開口した止め板摺動用空間部１８が形成され、
左、右側壁部１５、１５の外側がそれぞれ左、右下段部２０、２０とされ、左、右下段部２０、２０にそれぞれ上下に貫通したバネ用孔２１、２１が穿設され、鉤状係止部１３の下部後壁部に後端開口２３が穿設され、
ヒンジ部９には、鉤状係止部１３の溝１２内に装着したヒンジピン１１が挿通部１４の上端挿通口１９から抜け出ることを規制する上下動自在の止め板２４と、止め板２４を押し上げる止め板用バネ２５とが設けられ、
止め板２４は、止め板摺動用空間部１８内を上下動する垂直壁部２６と、この垂直壁部２６の上端より前方に延びた水平壁部２７と、この水平壁部の前方上端より上方に延び、挿通部１４の上端挿通口１９を閉鎖するように前壁部１６に沿って設けられる止め壁部２８と、止め板摺動用空間部１８内から後端開口２３へ突出した指掛け部２９とが一体形成されたものであり、
止め板用バネ２５の端部は、バネ用孔２１、２１を形成する側壁に係止され、止め板２４を止め板用バネ２５に抗して押し下げると、挿通部１４の上端挿通口１９が開放されて、蓋体７のヒンジピン１１を取り外すことができるとする構成としている。
