Description

【０００１】
【発明の属する技術分野】
本発明は、蓋体を容器本体に蝶番ピンなしでヒンジ連結することができるコンパクト容器に関するものである。
【０００２】
【従来の技術】
一般に、ファンデーション等の化粧料を収容して携帯するコンパクト容器としては、容器本体に、化粧料が充填された中皿が収容され、この容器本体の後端部に、下面に鏡が貼着された蓋体が開閉自在にヒンジ連結されたものが用いられている。このようなコンパクト容器として、例えば、図１７に示すようなものがある。このコンパクト容器は、容器本体４６の後端部に切欠凹部４７が形成され、この切欠凹部４７に、蓋体４８の裏面後端から垂下する連結片４９が配設されている。そして、この連結片４９は、図１８に示すように、上記切欠凹部４７の左右側面の軸穴（図では隠れて見えない）と連結片４９の先端の貫通穴５０に蝶番ピン５１を嵌挿することにより容器本体４６にヒンジ連結されている。
【０００３】
【発明が解決しようとする課題】
ところが、上記コンパクト容器では、容器本体４６と蓋体４８を蝶番ピン５１を用いてヒンジ連結しているため、連結片４９に貫通穴５０を穿設するとともに、切欠凹部４７にも軸穴を穿設する必要がある。このため、穴開けのために金型が複雑になるという問題がある。しかも、上記蝶番ピン５１を貫通穴５０および軸穴に嵌挿させて蓋体４８を取り付ける組付け作業に非常に手間がかかり、コストアップになるという問題もある。
【０００４】
そこで、蝶番ピンを使用しないで蓋体をヒンジ連結させるものとして、例えば、実願平２−１２７６９９号公報（実開平４−８３１０６号公報）に示すコンパクト容器が提案されている。このものは、図１９に示すように、プラスチック製で、上面に中皿（図示せず）を収容するための収容部３３を有する容器本体３１と、裏面に鏡３２ａが貼着された蓋体３２とで構成されている。上記容器本体３１の後端面には、切欠部３４が形成されており、この切欠部３４の相対向する両側面に上端側が開放した縦溝３５が形成されている。上記蓋体３２の裏面後端には、上記切欠部３４に取り付けられる連結片３６が垂設され、この連結片３６の左右両側面には、上記縦溝３５に摺動自在に嵌合する回転軸部３７が突設されている。３８は上記切欠部３４の奥面に横設された突条であり、この突条３８を囲うように略Ｕ字状の切抜部４０が上記切欠部３４の奥面部に形成され、この切抜部４０の内側が弾性片４１になっている。上記突条３８は、上記切欠部３４に連結片３６を取り付けた際に、閉蓋状態で連結片３６の前面に形成された抜け止め凹部３９内に入り込むように嵌合し、連結片３６が上方に抜けないように抜け止めされるようになっている。なお、上記容器本体３１の前端面に形成された切欠凹部４２の奥面に形成された係合突起４３と、上記蓋体３２の前端部に形成された係合爪４４との係合により閉蓋状態が保持される。また、上記切欠凹部４２に進退自在に取り付けられた操作片４５を押圧することによりワンタッチで開蓋するようになっている。
【０００５】
上記コンパクト容器において、蓋体３２を取り付ける場合には、まず蓋体３２を容器本体３１の上方に位置させ、回転軸部３７を縦溝３５の上端部に位置合わせする。この状態で、連結片３６を切欠部３４の下側に押し込むと、連結片３６の下端が突条３８に当接した状態になる。この状態からさらに連結片３６を下側に押すと、切欠部３４の弾性片４１を前側に反らせながら連結片３６が突条３８を乗り越えてその下側に位置し、かつ回転軸部３７が縦溝３５の下端に位置した状態になり、蓋体３２が容器本体３１に取り付けられる。また、蓋体３２を容器本体３１から取り外す場合には、上記とは逆に、蓋体３２を上方に持ち上げ、回転軸部３７を縦溝３５に沿って上方に移動させると、連結片３６が弾性片４１を前側に反らせながら突条３８を乗り越えて、回転軸部３７が縦溝３５の上端から抜けて蓋体３２が容器本体３１から取り外されるようになっている。
【０００６】
しかしながら、上記コンパクト容器では、蓋体３２を取り付けたときの連結片３６の位置決めと抜け止めを、弾性片４１に設けられた突条３８によって行うため、上記連結片３６に弾性片４１の弾性力を上回る力が働くと、蓋体３２が容易に容器本体３１から外れてしまうという問題がある。しかも、縦溝３５が上方に開放し、蓋体３２は容器本体１の上側から取り付けるようになっていることから、蓋体３２の回動角度にかかわらず、たとえ閉蓋状態であっても、連結片３６に上方向の力が加わると、回転軸部３７は縦溝３５に沿って上方に移動して蓋体３２が外れるため、誤ってコンパクト容器を床面に落下させた場合等、不用意に蓋体３２が容器本体３１から外れやすいという問題がある。また、容器本体３１に弾性片４１を形成するためにＵ字状の切抜部４０を設けなければならず、それだけ構造が複雑になり、それに伴い成形金型も非常に複雑なものになるため、製造コストが高くなるという問題もある。しかも、上記弾性片４１は曲がりやすいため、この部分から容器が破損しやすいという問題もある。さらに、上記コンパクト容器では、連結片３６が突条３８を乗り越えてその下側に位置決めされた状態では、上記突条３８は連結片３６の上側に位置するだけであり、蓋体３２の回動が規制されない。したがって、回動途中で蓋体３２から手指を離すと蓋体３２は倒れてしまうため、使用中に蓋体３２の裏面に貼着された鏡３２ａを覗く際には、蓋体３２を常に手指で把持しておかなければならず、使い勝手が悪いという問題もある。
【０００７】
本発明は、このような事情に鑑みなされたもので、蓋体を蝶番ピンなしでヒンジ連結することができるうえ、構造が簡単で安価に作製でき、しかも、蓋体を所望の角度で保持することができて使い勝手のよいコンパクト容器の提供をその目的とする。
【０００８】
【課題を解決するための手段】
上記の目的を達成するため、本発明の請求項１にかかるコンパクト容器は、上面に収容部が凹設された容器本体と、この容器本体の上面を蓋する蓋体とを備え、上記容器本体の後端面に切欠部を形成し、この切欠部の相対向する両内側面にそれぞれ均一幅の縦溝を設け、この縦溝の下端側を開放し、上記蓋体の後端に上記切欠部に収まる大きさの連結片を設けるとともに、この連結片の左右両側面に上記縦溝内を摺動しその上端に回動自在に嵌合する回転軸部を突設し、上記切欠部の奥面に、上記回転軸部が上記縦溝の上端に位置した状態で上記連結片と係合してこの連結片を上記切欠部内に位置決めするとともに上記連結片を支受する位置決め凸部を形成し、上記切欠部の奥面の、位置決め凸部の上側に位置する部分に、蓋体が回動する際に連結片と摺接して回動を規制する摺接部を形成し、上記切欠部の奥面部と対面する上記連結片の面に閉蓋状態で上記摺接部が収まる凹部を形成し、蓋体を開いた状態で上記回転軸部を上記縦溝に嵌挿させることにより蓋体を容器本体にヒンジ連結させるようにしたことを特徴とするものである。
【０００９】
また、本発明の請求項２にかかるコンパクト容器は、上面に収容部が凹設された容器本体と、この容器本体の上面を蓋する蓋体とを備え、上記容器本体の後端面に切欠部を形成し、この切欠部の相対向する両内側面にそれぞれ縦溝を設け、この縦溝の下端側を開放し、上記蓋体の後端に上記切欠部に収まる大きさの連結片を設けるとともに、この連結片の左右両側面に上記縦溝内を摺動しその上端に回動自在に嵌合する回転軸部を突設し、上記切欠部の奥面に、上記回転軸部が上記縦溝の上端に位置した状態で上記連結片と係合してこの連結片を上記切欠部内に位置決めする位置決め凸部を形成し、上記切欠部の奥面の、位置決め凸部の上側に位置する部分に、蓋体が回動する際に連結片と摺接して回動を規制する摺接部を形成し、上記切欠部の奥面部と対面する上記連結片の面に閉蓋状態で上記摺接部が収まる凹部を形成し、蓋体を開いた状態で上記回転軸部を上記縦溝に嵌挿させることにより蓋体を容器本体にヒンジ連結させるようにしたコンパクト容器であって、切欠部の左右両内側面の上側部に、上記縦溝の上端部を中心とした上向きの弧状に段落ち形成された弧状段落ち部が形成され、上記連結片の左右両側面の下側部に、回転軸部が上記縦溝の上端に位置して回動する際上記弧状段落ち部と嵌合して摺接する弧状段部が形成されていることを特徴とするものである。
【００１０】
すなわち、本発明の請求項１にかかるコンパクト容器は、容器本体の切欠部に形成した均一幅の縦溝に、連結片の回転軸部を嵌挿させることにより、容器本体と蓋体をヒンジ連結するようにしているため、蝶番ピンが不要になる。また、上記縦溝の下端側を開放し、蓋体を下方から取り付けるようにしたことから、閉蓋状態ではたとえ外力が加わっても蓋体は外れない。したがって、誤ってコンパクト容器を床面に落下させた場合にも、従来のように不用意に蓋体が容器本体から外れるようなことがない。さらに、連結片は位置決め凸部と係合することにより切欠部内に位置決めされるとともに支受されるようになっており、容器本体には弾性片が設けられていないため、構造が簡単で、それに伴い成形金型も簡単なものですむため、製造コストが安くなる。しかも、曲がりやすく破損しやすい弾性片がないことから、容器自体が丈夫になる。さらに、容器本体への蓋体の取り付けは、蓋体を開けた状態で回転軸部を均一幅の縦溝に嵌挿させることにより容易に行えることから、組付けに手間がかからず、量産性がよく、一層コストが安くなる。そのうえ、このコンパクト容器では、蓋体が回動する際に連結片と摺接して回動を規制する摺接部が設けられているため、回動途中で蓋体から手指を離しても蓋体は倒れず、どの角度でもそのままの姿勢が保持されるため、使用中に蓋体の裏面の鏡を覗く際にも、蓋体を手指で把持する必要がなく、使い勝手が良い。
【００１１】
また、本発明の請求項２にかかるコンパクト容器は、切欠部の左右両内側面に弧状段落ち部を形成し、上記連結片の左右両側面に、回転軸部が上記縦溝の上端に位置して回動する際上記弧状段落ち部と嵌合して摺接する弧状段部を形成したため、蓋体の回動中に弧状段落ち部と弧状段部とが嵌合していることにより、連結片が抜け止めされ、上記嵌合が外れる角度まで蓋体を開蓋させなければ、回転軸部が縦溝から外れないため、開蓋操作中も蓋体が容易に外れなくなる。しかも、上記弧状段落ち部と弧状段部との摺接による摩擦によっても蓋体の回動が規制されてヒンジ部が確実に緊締されることから、使用中に蓋体の裏面に貼着された鏡を覗く際に、多少の振動等が加わっても蓋体が倒れず、使い勝手がよい。
【００１２】
【発明の実施の形態】
つぎに、本発明の実施の形態を図面にもとづいて詳細に説明する。
【００１３】
図１は、本発明のコンパクト容器の一実施形態を示している。このコンパクト容器は、プラスチック製で、上面に中皿（図示せず）を収容する収容部３が凹設された容器本体１と、この容器本体１の後端部にヒンジ連結され、その下面に鏡２ａが貼着された蓋体２とを備えている。
【００１４】
上記容器本体１には、その後端部に、切欠部４が形成されており、この切欠部４の相対向する両内側面に均一幅の縦溝５が形成され、この縦溝５の下端側が開放されている。一方、上記蓋体２の後端の上面には、上記切欠部４に取り付けられる連結片６が垂下され、この連結片６の左右両側面には、上記縦溝５に嵌挿されその上端に回動自在に嵌合する回転軸部７が突設されている。
【００１５】
８は上記切欠部４の奥面に横設された位置決め凸部であり、上記回転軸部７が縦溝５の上端に位置した状態で連結片６と係合し、上記連結片６を切欠部４内に位置決めするとともに上記連結片６を支受するようになっている。また、上記位置決め凸部８の上側の部分には、連結片６が位置決めされて蓋体２が回動する際に、連結片６と摺接して回動を規制する摺接リブ１２が形成されている。一方、上記連結片６には、その前面に凹部９が形成され、閉蓋状態で、上記凹部９内に上記摺接リブ１２が収まるようになっている。図において、１０は蓋体２の前端下面に垂下された係合爪であり、容器本体１の前面に形成された切欠凹部１ａ内の被係合部１１と係合して閉蓋状態を保持するようになっている。
【００１６】
より詳しく説明すると、上記容器本体１は、図２〜図６に示すように、平面視で略四角形に形成され、上面に中皿を収容する収容部３が凹設されている。この収容部３の開口縁の左右両側と前側は、外向きに傾斜する傾斜面３ａに形成されている。この容器本体１の後端部には、切欠部４が切り欠き形成されており、この切欠部４の両内側面に、下側に開放する均一幅の縦溝５が形成されている。また、上記切欠部４の奥面には、位置決め凸部８が横設され、この位置決め凸部８の上側には、図７に示すように、薄板状の摺接リブ１２が一体的に形成されている。この摺接リブ１２の分だけ、容器本体１の収容部３の後壁が厚くなり、容器本体１自体の強度も向上するようになっている。さらに、上記切欠部４の両内側面の上側部には、上記縦溝５の上端部を中心として上向きの弧状を描きこの弧状の上側部分が段落ち形成された弧状段落ち部１５が形成されている。そして、この容器本体１の前面には、切欠凹部１ａが形成され、蓋体２の係合爪１０と係合する被係合部１１が形成されている。図２および図３および図５において、１９は中皿を取り外すときに細棒等を差し込む小孔である。
【００１７】
上記蓋体２は、図８〜図１１に示すように、上記容器本体１と同じく平面視で略四角形に形成されている。この蓋体２は、下面に凹部１３ａが形成され、この凹部１３ａの奥面（蓋体２の下面）に、鏡２ａが貼着されている。そして、この蓋体２の後端部には、上記切欠部４に収まる連結片６が垂設されている。この連結片６の左右両側面に、上記切欠部４の縦溝５に嵌合する回転軸部７が突設され、さらに、この連結片６の左右両側面の上記回転軸部７の上側の部分に、上記回転軸部７を中心に上向きの弧状を描き、回転軸部７が上記縦溝５の上端に位置して回動する際上記弧状段落ち部１５と嵌合して摺接する弧状段部１４が形成されている。また、上記連結片６の前面には、閉蓋状態で上記切欠部４の摺接リブ１２が収まる凹部９が凹設されている。そして、この連結片６は、その下端が凸面部１８に形成されている。一方、この容器本体１の前端部の下面には、上記容器本体１の被係合部１１と係合する係合爪１０が垂設されている。
【００１８】
上記構成のコンパクト容器において、容器本体１に蓋体２を取り付ける場合には、図１２に示すように、まず、容器本体１の後側に蓋体２を起立させた状態で配設し、切欠部４の縦溝５の下側の開口部に連結片６の回転軸部７を位置合わせする。ついで、蓋体２を上方にスライドさせて回転軸部７を均一幅の縦溝５に嵌挿させ、さらに連結片６を押し込むと、図１３に示すように、連結片６の凸面部１８が位置決め凸部８を乗り越えて係合する。この状態で回転軸部７が縦溝５の上端位置で回動自在に嵌合するようになっている。つぎに、蓋体２を前方に回動させると、図１４に示すように、連結片６の凸面部１８が上記摺接リブ１２と摺接しながら蓋体２が前方に回動し、このとき、その摩擦力により蓋体２の回動が規制され、回動途中で蓋体２から手指を離しても蓋体２は倒れずにそのままの姿勢が保持されるようになっている。しかも、この回動の際、上記切欠部４の両内側面の弧状段落ち部１５と、連結片６の左右両側面の弧状段部１４が嵌合し、蓋体２の抜け止めをする。また、上記弧状段落ち部１５と弧状段部１４の摺接摩擦によっても回動が規制されるようになっている。さらに蓋体２を回動させて、図１５に示すように、前端部の係合爪１０と被係合部１１とを係合させることにより閉蓋される。この閉蓋状態では、連結片６の凹部９内に摺接リブ１２が収まり、閉蓋の際の妨げにならないようになっている。
【００１９】
一方、このコンパクト容器を開蓋させる場合には、まず、蓋体２の前端部の係合爪１０と、容器本体１の切欠凹部１ａに手指を掛け、蓋体２を上方に少し引き上げ、被係合部１１と係合爪１０の係合を解除する。ついで、蓋体２を所望の角度まで後方に回動させて開蓋させる。この開蓋動作の際、蓋体２の開蓋角度が小さいうちは、上記弧状段落ち部１５と弧状段部１４との摺接部分が大きいことから、開蓋抵抗が大きく、開蓋角度が大きくなるにしたがって上記弧状段落ち部１５と弧状段部１４の摺接部分が少なくなって開蓋抵抗がしだいに小さくなる。これにより、誤って係合爪１０と被係合部１１の係合が外れた際に、開蓋角度が小さいうちは開蓋抵抗が大きいことから、それ以上開蓋するのを防ぎ、実際に使用の際の開蓋操作の際は、開蓋抵抗が開蓋角度が大きくなるにしたがって開蓋抵抗が小さくなることから、スムーズに開蓋できるようになっている。また、開蓋状態では、図１６に示すように、連結片６の左右両側面の弧状段部１４の後端部１４ａが容器本体の後端部と当接することにより当たり止めされるようになっている。
【００２０】
一方、容器本体１から蓋体２を取り外す場合には、上記と逆に、まず、蓋体２を略９０度程度まで開蓋させて上記弧状段落ち部１５と弧状段部１４の嵌合を解除し（図１３参照）、この状態で蓋体２を下方に向かって容器本体１から引き離すように力を加えると、位置決め凸部８と連結片６との係合が解除され、回転軸部７が均一幅の縦溝５から抜けて、蓋体２は容器本体１から容易に取り外される。
【００２１】
このように、上記コンパクト容器では、閉蓋状態ではたとえ外力が加わっても蓋体２は外れない。また、容器本体１には弾性片が設けられていないため、構造が簡単になる。しかも、曲がりやすく破損しやすい弾性片がないうえ、摺接リブ１２による補強効果と相まって、容器自体が丈夫になる。さらに、回動途中で蓋体２から手指を離してもそのままの姿勢が保持される。また、蓋体２の回動中に弧状段落ち部１５と弧状段部１４とが嵌合して連結片６が抜け止めされているため、上記嵌合が外れる角度まで蓋体２を開蓋させなければ、回転軸部７が縦溝５から外れないため、開蓋操作中も蓋体が容易に外れなくなる。しかも、上記弧状段落ち部１５と弧状段部１４との摺接による摩擦によっても蓋体２の回動が規制されてることから、多少の振動等が加わっても蓋体が倒れず、使い勝手がよい。しかも、蓋体２を着脱する場合には、蓋体２を起こして開蓋状態にしてから回転軸部７を均一幅の縦溝５に嵌挿させることにより容易に着脱することができる。このため、容器本体１から蓋体２だけを取り外して、手鏡として携帯することができ、蓋体２もしくは容器本体１の一方を失ったり破損したりしても、交換することができる。さらに、上記容器本体１の収容部３の周縁に傾斜面３ａを形成したことから、中皿を収容する場合にガイドとなって収容しやすい。
【００２２】
【発明の効果】
以上のように、本発明の請求項１にかかるコンパクト容器によれば、容器本体の切欠部に形成した均一幅の縦溝に、連結片の回転軸部を嵌挿させることにより、容器本体と蓋体をヒンジ連結するようにしているため、蝶番ピンが不要になる。また、上記縦溝の下端側を開放し、蓋体を下方から取り付けるようにしたことから、閉蓋状態ではたとえ外力が加わっても蓋体は外れない。したがって、誤ってコンパクト容器を床面に落下させた場合にも、従来のように不用意に蓋体が容器本体から外れるようなことがない。さらに、連結片は位置決め凸部と係合することにより切欠部内に位置決めされるとともに支受されるようになっており、容器本体には弾性片が設けられていないため、構造が簡単で、それに伴い成形金型も簡単なものですむため、製造コストが安くなる。しかも、曲がりやすく破損しやすい弾性片がないことから、容器自体が丈夫になる。さらに、容器本体への蓋体の取り付けは、蓋体を開けた状態で回転軸部を均一幅の縦溝に嵌挿させることにより容易に行えることから、組付けに手間がかからず、量産性がよく、一層コストが安くなる。そのうえ、このコンパクト容器では、蓋体が回動する際に連結片と摺接して回動を規制する摺接部が設けられているため、回動途中で蓋体から手指を離しても蓋体は倒れず、どの角度でもそのままの姿勢が保持されるため、使用中に蓋体の裏面の鏡を覗く際にも、蓋体を手指で把持する必要がなく、使い勝手が良い。
【００２３】
また、本発明の請求項２にかかるコンパクト容器によれば、切欠部の左右両内側面に弧状段落ち部を形成し、上記連結片の左右両側面に、回転軸部が上記縦溝の上端に位置して回動する際上記弧状段落ち部と嵌合して摺接する弧状段部を形成したため、蓋体の回動中に弧状段落ち部と弧状段部とが嵌合していることにより、連結片が抜け止めされ、上記嵌合が外れる角度まで蓋体を開蓋させなければ、回転軸部が縦溝から外れないため、開蓋操作中も蓋体が容易に外れなくなる。しかも、上記弧状段落ち部と弧状段部との摺接による摩擦によっても蓋体の回動が規制されてヒンジ部が確実に緊締されることから、使用中に蓋体の裏面に貼着された鏡を覗く際に、多少の振動等が加わっても蓋体が倒れず、使い勝手がよい。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a compact container capable of hinge-connecting a lid to a container body without a hinge pin.
[0002]
[Prior art]
In general, as a compact container for carrying cosmetics such as a foundation, a medium plate filled with cosmetics is housed in a container body, and a mirror is attached to the rear end of the container body on the lower surface. A lid is hinged so as to be openable and closable. As such a compact container, for example, there is a container as shown in FIG. In this compact container, a notch concave portion 47 is formed at the rear end of the container body 46, and a connecting piece 49 hanging from the rear rear end of the lid 48 is provided in the notch concave portion 47. Then, as shown in FIG. 18, the hinge pin 51 is inserted into the axial holes (hidden and invisible in the drawing) on the left and right side surfaces of the notch recess 47 and the through hole 50 at the tip of the coupling piece 49. By doing so, it is hingedly connected to the container body 46.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned compact container, since the container body 46 and the lid 48 are hingedly connected using the hinge pin 51, the connecting piece 49 is provided with the through hole 50 and the cutout recess 47 is provided with the axial hole. Need to be set up. For this reason, there is a problem that the mold is complicated due to the perforation. In addition, there is also a problem that the assembling work of fitting the hinge pin 51 into the through-hole 50 and the shaft hole and attaching the lid 48 is extremely troublesome, resulting in an increase in cost.
[0004]
Therefore, a compact container disclosed in Japanese Utility Model Application Laid-Open No. 2-127699 (Japanese Utility Model Application Laid-Open No. 4-83106) has been proposed as one in which the lid is hinged without using a hinge pin. As shown in FIG. 19, this is made of plastic and has a container body 31 having an accommodation portion 33 for accommodating an inner plate (not shown) on the upper surface, and a lid body having a mirror 32a attached to the back surface. 32. A notch 34 is formed in the rear end surface of the container body 31, and a vertical groove 35 whose upper end is open is formed on both opposing side surfaces of the notch 34. At the rear end of the back surface of the lid 32, a connecting piece 36 attached to the notch 34 is vertically provided. On both left and right side faces of the connecting piece 36, a rotary fitting slidably fitted to the vertical groove 35 is provided. A shaft portion 37 is protruded. Reference numeral 38 denotes a ridge provided laterally on the inner surface of the notch 34. A substantially U-shaped cutout 40 is formed on the inner surface of the notch 34 so as to surround the ridge 38. The inside of 40 is an elastic piece 41. When the connecting piece 36 is attached to the notch 34, the ridge 38 fits into a retaining recess 39 formed on the front surface of the connecting piece 36 in a closed state, and the connecting piece 36 is fitted. It is designed to prevent it from falling out. The lid 32 is closed by the engagement of an engagement projection 43 formed on the inner surface of the notch recess 42 formed on the front end surface of the container body 31 and an engagement claw 44 formed on the front end of the lid 32. The lid state is maintained. In addition, the cover is opened with one touch by pressing an operation piece 45 attached to the notch recess 42 so as to be able to move forward and backward.
[0005]
When the lid 32 is attached to the compact container, first, the lid 32 is positioned above the container body 31, and the rotation shaft 37 is aligned with the upper end of the vertical groove 35. In this state, when the connecting piece 36 is pushed below the notch 34, the lower end of the connecting piece 36 comes into contact with the ridge 38. When the connecting piece 36 is further pushed downward from this state, the connecting piece 36 rides over the ridge 38 and is positioned below the ridge 38 while the elastic piece 41 of the notch 34 is warped forward. The lid 32 is attached to the container body 31 in a state of being located at the lower end of the groove 35. When removing the lid 32 from the container body 31, the lid 32 is lifted upward and the rotating shaft 37 is moved upward along the vertical groove 35, and the connecting piece 36 is disengaged. The rotating shaft 37 comes off from the upper end of the vertical groove 35 and the lid 32 is detached from the container body 31 while the elastic piece 41 gets over the ridge 38 while warping the elastic piece 41 to the front side.
[0006]
However, in the above-mentioned compact container, since the positioning and the retaining of the connecting piece 36 when the lid 32 is attached are performed by the ridge 38 provided on the elastic piece 41, the elastic force of the elastic piece 41 is applied to the connecting piece 36. If a force greater than the above is applied, there is a problem that the lid 32 easily comes off the container body 31. Moreover, since the vertical groove 35 is opened upward and the lid 32 is attached from above the container body 1, regardless of the rotation angle of the lid 32, even if the lid is in the closed state, When an upward force is applied to the connecting piece 36, the rotating shaft 37 moves upward along the vertical groove 35 and the lid 32 comes off, so that if the compact container is dropped on the floor by mistake, There is a problem that the lid 32 is easily detached from the container body 31. In addition, a U-shaped cutout 40 must be provided in order to form the elastic piece 41 in the container main body 31, which complicates the structure and the molding die becomes extremely complicated. There is also a problem that the manufacturing cost increases. In addition, since the elastic piece 41 is easily bent, there is a problem that the container is easily damaged from this portion. Further, in the above-described compact container, when the connecting piece 36 is positioned over the protruding piece 38 over the protruding piece 38, the protruding piece 38 is only located above the connecting piece 36, and the rotation of the lid 32 is performed. Is not regulated. Therefore, when the user releases his / her finger from the lid 32 during the rotation, the lid 32 falls down. When looking into the mirror 32a attached to the back of the lid 32 during use, the lid 32 is always There is also a problem that it is inconvenient to use.

Further, an arc-shaped stepped-down portion 15 is formed in an upper portion of both inner side surfaces of the cutout portion 4 with an upward arc drawn around the upper end of the vertical groove 5 and the upper portion of the arc-shaped step is formed. ing. A cutout recess 1 a is formed on the front surface of the container body 1, and an engaged portion 11 that engages with the engaging claw 10 of the lid 2 is formed. In FIGS. 2, 3 and 5, reference numeral 19 denotes a small hole into which a thin rod or the like is inserted when the inner plate is removed.
[0017]
As shown in FIGS. 8 to 11, the lid 2 is formed in a substantially quadrangular shape in plan view similarly to the container body 1. A concave portion 13a is formed on the lower surface of the lid 2, and a mirror 2a is attached to the inner surface of the concave portion 13a (the lower surface of the lid 2). At the rear end of the lid 2, a connecting piece 6 that fits in the cutout 4 is vertically provided. On both left and right sides of the connecting piece 6, a rotating shaft portion 7 that fits into the vertical groove 5 of the cutout portion 4 is provided in a protruding manner. In this portion, an arc is drawn upward with the rotation shaft 7 as a center. When the rotation shaft 7 is positioned at the upper end of the vertical groove 5 and rotates, the arc is fitted with the arc-shaped step-down portion 15 and slidably contacts. A step 14 is formed. A recess 9 is provided on the front surface of the connecting piece 6 so that the sliding contact rib 12 of the cutout 4 can be accommodated in a closed state.

On the other hand, an engaging claw 10 that engages with the engaged portion 11 of the container body 1 is vertically provided on the lower surface of the front end of the container body 1.
[0018]
When the lid 2 is attached to the container main body 1 in the compact container having the above configuration, as shown in FIG. The rotation shaft 7 of the connecting piece 6 is aligned with the lower opening of the vertical groove 5 of the portion 4. Then, the cover 2 is slid upward to fit the rotary shaft 7 into the longitudinal groove 5 having a uniform width, and furthermore, the connecting piece 6 is pushed in. As shown in FIG. It engages over the positioning projection 8. In this state, the rotating shaft 7 is rotatably fitted at the upper end position of the vertical groove 5. Next, when the cover 2 is rotated forward, as shown in FIG. 14, the cover 2 rotates forward while the convex surface portion 18 of the connecting piece 6 is in sliding contact with the sliding contact rib 12. The rotation of the lid 2 is regulated by the frictional force, so that even if the user releases his / her finger from the lid 2 during the rotation, the lid 2 does not fall down and is kept in the same posture. In addition, at the time of this rotation, the arc-shaped stepped portions 15 on both inner side surfaces of the cutout portion 4 and the arc-shaped stepped portions 14 on both right and left side surfaces of the connecting piece 6 are fitted to prevent the lid 2 from coming off. Further, the rotation is also restricted by the sliding friction between the arc-shaped stepped portion 15 and the arc-shaped stepped portion 14. Further, the cover 2 is closed by rotating the lid 2 to engage the engaging claw 10 at the front end with the engaged portion 11 as shown in FIG. In this closed state, the sliding contact rib 12 is accommodated in the concave portion 9 of the connecting piece 6 so as not to hinder the closing operation.

On the other hand, when opening the lid of the compact container, first, fingers are placed on the engaging claw 10 at the front end of the lid 2 and the notch 1a of the container body 1, and the lid 2 is slightly lifted upward to cover the lid. The engagement between the engagement portion 11 and the engagement claw 10 is released. Next, the lid 2 is rotated backward to a desired angle to open the lid. During this opening operation, while the opening angle of the lid 2 is small, the sliding contact between the arc-shaped stepped portion 15 and the arc-shaped step portion 14 is large, so that the opening resistance is large and the opening angle is small. As the size increases, the sliding contact portion between the arc-shaped stepped portion 15 and the arc-shaped stepped portion 14 decreases, and the lid opening resistance gradually decreases. Thereby, when the engaging claw 10 is disengaged from the engaged portion 11 by mistake, since the lid opening resistance is large while the lid opening angle is small, it is prevented that the lid is further opened, and At the time of the opening operation at the time of use, since the opening resistance decreases as the opening angle increases, the opening can be smoothly performed. Further, in the open state, as shown in FIG. 16, the rear ends 14a of the arc-shaped steps 14 on the right and left sides of the connecting piece 6 come into contact with the rear end of the container main body so as to be stopped. ing.
[0020]
On the other hand, when removing the lid 2 from the container body 1, on the contrary, first, the lid 2 is opened to about 90 degrees to fit the arc-shaped stepped portion 15 and the arc-shaped step 14. When the lid 2 is released (see FIG. 13) and a force is applied to pull the lid 2 downward and away from the container body 1 in this state, the engagement between the positioning projection 8 and the connecting piece 6 is released, and the rotation shaft portion is released. The cover 2 is easily removed from the container body 1 when the 7 comes out of the longitudinal groove 5 having a uniform width .
[0021]
Thus, in the above-mentioned compact container, the lid 2 does not come off even when an external force is applied in the closed state. Further, since no elastic piece is provided on the container body 1, the structure is simplified. In addition, there is no elastic piece that is easily bent and damaged, and the container itself becomes strong in combination with the reinforcing effect of the sliding contact rib 12. Furthermore, even if the finger is released from the lid 2 during the rotation, the posture is maintained as it is. Also, since the arc-shaped stepped portion 15 and the arc-shaped stepped portion 14 are fitted during the rotation of the lid 2 to prevent the connection piece 6 from coming off, the lid 2 is opened until the fitting is released. Otherwise, the rotating shaft 7 does not come off the vertical groove 5, so that the lid does not come off easily even during the opening operation. In addition, since the rotation of the lid 2 is also restricted by the friction caused by the sliding contact between the arc-shaped stepped portion 15 and the arc-shaped stepped portion 14, the lid does not fall down even if some vibration or the like is applied, and the usability is improved. Good. Moreover, when attaching and detaching the cover 2, the cover 2 can be easily attached and detached by raising the cover 2 to open the cover, and then inserting the rotating shaft portion 7 into the vertical groove 5 having a uniform width . For this reason, it is possible to remove only the lid 2 from the container body 1 and carry it as a hand mirror, and even if one of the lid 2 or the container body 1 is lost or damaged, it can be replaced. Further, since the inclined surface 3a is formed on the peripheral edge of the storage portion 3 of the container body 1, it becomes easy to store the inner plate as a guide when storing the inner plate.
