【０００１】
【発明の属する技術分野】
本発明は、携帯容易に化粧料を収納する気密化粧料容器に関し、とりわけ化粧皿を収納する容器本体に蓋体が開閉自在に蝶着され、蓋体の裏側に設けたパッキン材が化粧皿の周縁部上面に圧接されるようになった気密化粧料容器に関する。
【０００２】
【従来の技術】
一般に、化粧料の携帯用にコンパクト等の化粧料容器が用いられるが、該化粧料容器は化粧料を詰めた化粧皿を容器本体に設けると共に、該容器本体の後端部に開閉自在に蓋体を蝶着し、該蓋体で容器本体上側を覆うようになっている。そして、容器本体と蓋体との前端部間に設けられるフック機構で蓋体の閉止状態が保持され、かつ、該フック機構を解除するための操作部が容器本体の前端部から突出されるのが一般的な構造となっている。
【０００３】
ところで、この種の化粧料容器では化粧皿の気密性を保持するにあたって、例えば実公平６−２５８５号公報に開示されるように蓋体の裏側にパッキン材を設け、蓋体を閉止した際に該パッキン材が化粧皿の周縁部上面に圧接されるようになっている。しかしながら、かかる従来の気密化粧料容器にあっては、パッキン材による気密保持精度を高く維持するために、蓋体と容器本体との蝶着部分に高い精度が要求される。
【０００４】
そこで、蓋体の蝶着部分の精度に影響されることなく化粧皿内の気密性を十分に確保することができる化粧料容器が、特開平８−１９１７１２号公報として本出願人により提案されている。即ち、該化粧料容器は、容器本体に回転自在に支持した回転枠に化粧皿を収納し、該回転枠および上記蓋体に互いに係合可能な係合突起を設けて、これら係合突起を介して回転枠の周縁部を蓋体に直接係止させるようになっている。このように回転枠と蓋体とを直接係止することにより、蓋体の蝶着部分に関係なくパッキン材と化粧皿の周縁部上面との気密精度を高く保持できる。また、上記回転枠には操作部としての操作ボタンを一体に設けると共に、当該回転枠を係合突起の係止方向に回転付勢する付勢手段を設けてあり、上記操作ボタンを操作して回転枠を付勢手段の付勢力に抗して回転することにより、該回転枠の係合突起と蓋体の係合突起との係合を離脱できるようになっている。
【０００５】
【発明が解決しようとする課題】
しかしながら、かかる従来の気密化粧料容器にあっては、回転枠に化粧皿を収納する際、回転枠の内側面に突設したダボと、化粧皿の外側面に凹設した係合凹部とを互いに係合させる等して、これら回転枠と化粧皿とが一体に回転されるようになっている。このため、回転枠および蓋体に設けた係合突起の係合を離脱させるために、操作ボタンを操作して回転枠を回転する場合には、化粧皿も一緒に回転されることになる。すると、該化粧皿はこれの周縁部上面に圧接されているパッキン材と擦れつつ相対回転されるため、該パッキン材が損傷を受けやすくなってその耐久性が低下されてしまう。また、上記回転枠と共に回転する化粧皿には化粧料が詰められているため、これら化粧皿および化粧料によって回転部分の重量が増大される。このため、回転枠を回転する際には、上記化粧皿とパッキン材とが圧接状態で擦れるときの摺動抵抗と合わせて、上記操作ボタンの操作が著しく重くなり、延いては、蓋体の開動操作性が悪化してしまうという課題があった。
【０００６】
そこで、本発明はかかる従来の課題に鑑みて、容器本体と蓋体の蝶着部分の精度に関係なく化粧皿内の気密性を高く保持しつつパッキン材の耐久性を向上し、かつ、操作ボタンの操作力を軽くして操作性を向上するようにした気密化粧料容器を提供することを目的とする。
【０００７】
【課題を解決するための手段】
かかる目的を達成するために請求項１に示す本発明の気密化粧料容器は、化粧皿を設けた容器本体と、該容器本体に開閉自在に蝶着される蓋体とを備え、該蓋体の裏側に設けたパッキン材が該蓋体の閉止状態で該化粧皿の周縁部上面に圧接されて、該化粧皿の内方を気密状態に保持するようになった気密化粧料容器において、上記容器本体から一体に上記化粧皿を取り付ける支持部を設ける一方、該支持部の外側に回転自在にリング状フックピースを設け、該リング状フックピースを一方向に回転付勢する付勢手段を設けると共に、上記容器本体に形成した開口部から突設されて該リング状フックピースに該付勢手段の付勢力に抗して回転力を付与する操作部を設け、かつ、該リング状フックピースの外側周方向に適宜間隔をもって複数の第１係合突起を突設すると共に、上記蓋体にこれの閉止状態で該第１係合突起にそれぞれ係合される複数の第２係合突起を設ける構成とする。
【０００８】
また、請求項２に示す本発明の気密化粧料容器は、化粧皿を設けた容器本体と、該容器本体に開閉自在に蝶着される蓋体と、該容器本体と該蓋体との間に配置され該容器本体に開閉自在に蝶着される中蓋とを備え、該中蓋の裏側に設けたパッキン材が該中蓋の閉止状態で該化粧皿の周縁部上面に圧接されて、該化粧皿の内方を気密状態に保持するようになった気密化粧料容器において、上記容器本体から一体に上記化粧皿を取り付ける支持部を設ける一方、該支持部の外側に回転自在にリング状フックピースを設け、該リング状フックピースを一方向に回転付勢する付勢手段を設けると共に、上記容器本体に形成した開口部から突設されて該リング状フックピースに該付勢手段の付勢力に抗して回転力を付与する操作部を設け、かつ、該リング状フックピースの外周に第１係合突起を設けると共に、上記蓋体にこれの閉止状態で該第１係合突起に係合される第２係合突起を設け、かつ、上記リング状フックピースの外側周方向に適宜間隔をもって複数の第３係合突起を突設すると共に、上記中蓋にこれの閉止状態で該第３係合突起にそれぞれ係合される複数の第４係合突起を設ける構成とする。
【０００９】
以上の構成により本発明の気密化粧料容器の作用を以下述べると、請求項１では容器本体から一体に設けた支持部の外側にリング状フックピースが回転自在に設けられており、蓋体の閉止時には、該蓋体に設けた第２係合突起が上記リング状フックピースに設けた第１係合突起に係合することで蓋体の閉止状態が保持され、この閉止状態で上記支持部に取り付けた化粧皿の周縁部上面に蓋体の裏側に設けたパッキン材が圧接して、該化粧皿内方が気密状態に保持される。
【００１０】
このとき、上記第１係合突起はリング状フックピースの外周に適宜間隔をもって複数が突設され、それぞれの第１係合突起に上記第２係合突起が係合されることにより、これら複数の係合部分によってパッキン材が化粧皿に圧接される状態を保持することができる。従って、上記第１，第２係合突起の係合のみによって化粧皿の気密保持を行うことができるため、容器本体と蓋体との蝶着部分の精度が化粧皿の密閉に影響することはなく、該蝶着部分の構成および組付け作業を簡単化することができる。
【００１１】
そして、容器本体の開口部から突設する操作部を操作してリング状フックピースを付勢手段に抗して回転することにより、上記第１係合突起と上記第２係合突起との係合状態を離脱して蓋体を開動可能状態とし、この状態で蓋体を手で開けることにより化粧皿の開口部を開放することができる。
【００１２】
このとき、該化粧皿は容器本体から一体に設けた支持部に取り付けられる一方、上記リング状フックピースは該支持部の外側に回転自在に設けられるため、化粧皿は容器本体側に固定された状態でリング状フックピースのみが単独で回転されることになる。従って、蓋体を開動するために操作部を操作してリング状フックピースを回転する場合に、化粧皿とこれの周縁部上面に圧接する上記パッキン材との擦れを無くすことができ、延いては、該パッキン材が損傷されるのを防止してこれの耐久性を向上することができる。
【００１３】
また、化粧皿とパッキン材との相対回転による摺動抵抗が無くなると共に、リング状フックピースの回転に化粧皿が伴われないことから回転部分を軽量化できるため、操作部の操作力を大幅に低減して蓋体の開動操作性を著しく向上することができる。
【００１４】
また、請求項２では、中蓋を設けた気密化粧料容器に本発明を適用したもので、該中蓋の裏側に化粧皿の周縁部上面に圧接されるパッキン材が設けられるようになっている。該気密化粧料容器では、リング状フックピースの外周に設けた第１係合突起と、蓋体に設けた第２係合突起との係合状態で、該蓋体の閉止状態が保持されると共に、上記リング状フックピースの外周に設けた複数の第３係合突起と、上記中蓋に設けた複数の第４係合突起との係合状態で、該中蓋の閉止状態が保持される。そして、蓋体および中蓋の閉止状態から操作部を操作してリング状フックピースを付勢手段の付勢力に抗して回転することにより、第１係合突起と第２係合突起との係合、および第３係合突起と第４係合突起との係合がそれぞれ離脱されて、蓋体および中蓋を開動可能状態とすることができる。上記中蓋の閉止状態では、上記支持部に取り付けた化粧皿の内方が中蓋の裏側に設けたパッキン材により気密状態に保持される。
【００１５】
このとき、上記第３係合突起はリング状フックピースの外周に適宜間隔をもって複数が突設され、それぞれの第３係合突起に中蓋に設けた上記第４係合突起が係合されるため、これら第３，第４係合突起の係合のみによって化粧皿の気密保持を行うことができる。従って、中蓋や蓋体の蝶着部分の精度が化粧皿の密閉に影響することはなく、該蝶着部分の構成および組付け作業を簡単化することができる。
【００１６】
また、上記化粧皿は容器本体から一体に設けた支持部に取り付けられ、かつ、上記リング状フックピースは該支持部の外側に回転自在に設けられるため、上記請求項１の構成と同様にリング状フックピースは単独で回転されることになる。従って、化粧皿と中蓋に設けた上記パッキン材との擦れを無くして、該パッキン材の耐久性を向上することができると共に、化粧皿とパッキン材との摺動抵抗を無くし、かつ、リング状フックピースの回転に伴う回転部分を軽量化できるため、操作部の操作力を大幅に低減して蓋体の開動操作性を著しく向上することができる。
【００１７】
【発明の実施の形態】
以下、本発明の実施形態を添付図面を参照して詳細に説明する。図１から図５は本発明の気密化粧料容器の第１実施形態を示し、図１は蓋体を半開した状態の斜視図、図２は蓋体を全開した状態の平面図、図３は図２中Ａ−Ａ線に対応する蓋体を閉止した状態の断面図、図４は図２中Ｂ−Ｂ線に対応する蓋体を閉止した状態の要部拡大断面図、図５は図２中Ｃ−Ｃ線に対応する蓋体を閉止した状態の要部拡大断面図である。
【００１８】
図１，図２に示すように本実施形態の気密化粧料容器１０は、容器本体１２と、該容器本体１２の後端部に蝶番１４を介して蝶着される蓋体１６とを備える。容器本体１２は周縁部が側壁１２ａによって囲まれた皿状を成しており、該側壁１２ａ内には容器本体１２の上側を覆うようにして中枠１８が嵌着される。蝶番１４は容器本体１２の後端部中央に形成される凹部１４ａに、蓋体１６の後端部中央に形成される凸部１４ｂが嵌合され、これら凹部１４ａと凸部１４ｂとに跨がって両側から蝶番ピン１４ｃを挿入することにより構成される。中枠１８は容器本体１２の上面を覆う被覆板１８ａと、容器本体１２の側壁１２ａの内周に嵌合される周壁１８ｂとを備え、図３に示すように該周壁１８ｂの外周には凸条１８ｃが形成される。そして、上記被覆板１８ａの周縁部が上記側壁１２ａの上端に載置されると共に、上記凸条１８ｃが上記側壁１２ａの内周に形成された凹条１２ｂに係合されることにより、中枠１８が容器本体１２に抜け止めされた状態で固定される。
【００１９】
上記容器本体１２の中心部から左側に片寄った位置に、該容器本体１２の底面１２ｃから一体に環状の支持部２０が突設され、該支持部２０に化粧料を詰め込むための化粧皿２２が収納される。該支持部２０は円形の筒状として形成される一方、上記化粧皿２２は周縁部に幅狭のフランジ２２ａを形成した深皿状に形成される。そして、支持部２０の内側に化粧皿２２が密接嵌合されるが、このとき、化粧皿２２の外周に形成した凹部２２ｂを、支持部２０の内周に形成したダボ２０ａに係合して化粧皿２２が抜け止めされる。また、上記支持部２０の上端には化粧皿２２のフランジ２２ａを係合する環状の段差部２０ｂが形成され、該段差部２０ｂに該フランジ２２ａが嵌合されることにより、該フランジ２２ａと支持部２０の上端とが面一に構成される。
【００２０】
上記中枠１８の被覆板１８ａには、上記支持部２０の上端部を嵌合する円形開口部１８ｄが形成されると共に、該円形開口部１８ｄに並設されて右側に片寄った位置に化粧具収納部１９が凹設される。また、上記円形開口部１８ｄの周縁部には、周方向に等間隔をもって配置されて正三角形の各頂点を構成するように小開口部１８ｅが３箇所形成されると共に、これら小開口部１８ｅは後述する第２係合突起３２および支柱３２ａが挿入可能な大きさに形成される。一方、上記蓋体１６の裏側１６ａには、上記化粧皿２２に対応する位置に環状凹部１６ｂが凹設され、該環状凹部１６ｂにパッキン材２４が嵌着されると共に、上記化粧具収納部１９に対応する位置に矩形状凹部１６ｃが凹設され、該矩形状凹部１６ｃに化粧鏡２６が嵌着される。上記パッキン材２４の周縁部には連続した環状のシール突起２４ａが形成され、蓋体１６の閉止状態で該シール突起２４ａの先端部が上記化粧皿２２のフランジ２２ａ上面に圧接されるようになっている。
【００２１】
筒状に形成された上記支持部２０の外周には、リング状フックピース２８が回転自在に密接嵌合される。該リング状フックピース２８の外周には、上記中枠１８に形成した小開口部１８ｅの形成位置に対応して３個の第１係合突起３０が周方向に等間隔に突設される。一方、上記蓋体１６の裏側１６ａには、上記パッキン材２４を囲うようにして上記第１係合突起３０にそれぞれ対応する位置に３本の支柱３２ａを突設し、これら支柱３２ａの先端部にはパッキン材２４を指向する側にそれぞれ第２係合突起３２が突設される。そして、上記支柱３２ａは蓋体１６の閉止時に上記小開口部１８ｅから挿入され、図４に示すように該蓋体１６が完全に閉止された状態で、第２係合突起３２は第１係合突起３０を乗り越えて互いに係合される。
【００２２】
また、図２に示すように上記リング状フックピース２８の外側には、前方右側から容器本体１２の前面中央部に向かって傾斜する操作部３４が一体に突設される。該操作部３４の先端部には弧状部分３４ａが形成され、図５に示すように該弧状部分３４ａを容器本体１２の側壁１２ａ前面の中央部に形成した開口部１２ｄから外方に突出させてある。このとき、上記開口部１２ｄに位置する上記中枠１８の周壁１８ｂには、該開口部１２ｄの形状に沿った切欠き部１８ｆが形成されている。更に、上記リング状フックピース２８の外側には、前方左側に付勢手段としての板ばね３６が一体に突設され、該板ばね３６の先端部右側を容器本体１２から突設した係止ピン３８に係止させてある。この状態で、上記リング状フックピース２８の図２中反時計回り方向の回転に対して、該リング状フックピース２８に戻し方向（図中時計回り方向）の回転付勢力を付与するようになっている。
【００２３】
以上の構成により本実施形態の気密化粧料容器１０は、図２に示すようにリング状フックピース２８は、自然状態では同図中破線に示すように板ばね３６により図中時計回り方向に戻された初期位置にあり、該リング状フックピース２８から突設する操作部３４は、先端の弧状部分３４ａが容器本体１２の開口部１２ｄから突設されている。また、リング状フックピース２８の上記初期位置では、中枠１８の小開口部１８ｅの直下に第１係合突起３０が位置している。そして、蓋体１６が閉止された状態では第２係合突起３２が第１係合突起３０に係合して、該蓋体１６の閉止状態が保持されると共に、パッキン材２４のシール突起２４ａが化粧皿２２のフランジ２２ａ上面に圧接されて、該化粧皿２２の内方が気密状態に密閉保持される。
【００２４】
次に、閉止状態にある上記蓋体１６を開放する際には、操作部３４の弧状部分３４ａを容器本体１２内方に向かって押すことにより、該操作部３４は押圧方向Ｐ（図２参照）に対して傾斜されているため、リング状フックピース２８は板ばね３６の付勢力に抗して反時計回り方向に回転する。すると、上記リング状フックピース２８に伴って第１係合突起３０が同方向に移動して第２係合突起３２との係合状態が離脱され、この状態で蓋体１６を手動で押し開けることができる。このとき、化粧皿２２のフランジ２２ａに圧接していたシール突起２４ａのスプリングバックにより蓋体１６が若干開かれるため、蓋体１６の開動が容易になる。そして、蓋体１６を開いた後に上記弧状部分３４ａから手を放してこれの押圧を解除することにより、リング状フックピース２８は板ばね３６の付勢力で時計回り方向に回転して初期位置に復帰される。この状態で蓋体１６を手動で閉止することにより、蓋体１６に設けた支柱３２ａが中枠１８の小開口部１８ｅから挿入され、該支柱３２ａ先端部の第２係合突起３２が上記第１係合突起３０に係合される。
【００２５】
ここで、上記蓋体１６の閉止状態は上記第１係合突起３０と第２係合突起３２との係合によって保持されるが、第１係合突起３０が化粧皿２２の周縁部を取り囲むように等間隔に３箇所配置されている。従って、３箇所配置された上記第１，第２係合突起３０，３２の係合のみによって、パッキン材２４が化粧皿２２に圧接された状態を保持して気密性を保持することができる。特に、本実施形態では、第１係合突起３０が等間隔に配置されるため、パッキン材２４を化粧皿１８の全周に略均等に圧接させることができる。このため、蓋体１６を容器本体１２に開閉自在に取り付ける蝶番１４の精度が、上記化粧皿１８の気密保持に影響されなくなり、延いては、該蝶番１４に高い精度が要求されなくなって、蝶番１４部分の構成および組付け作業を簡単化することができる。
【００２６】
ところで、上記化粧皿２２は容器本体１２から一体に設けた支持部２０に収納され、かつ、上記リング状フックピース２８は該支持部２０の外側に回転自在に設けられるため、化粧皿２２は容器本体１２側に固定された状態でリング状フックピース２８のみが単独で回転されることになる。従って、蓋体１６を開動するために操作部３４を操作してリング状フックピース２８を回転した場合にも、化粧皿２２は定位置で静止されて該化粧皿２２と、これのフランジ２２ａに圧接されたパッキン材２４との相対回転を防止することができる。このため、これら化粧皿２２とパッキン材２４との回転方向の擦れを無くすことができ、延いては、該パッキン材２４のシール突起２４ａが損傷されるのを防止して、該パッキン材２４の耐久性を向上することができる。
【００２７】
また、このように蓋体１６の開動操作時に、化粧皿２２とパッキン材２４との相対回転が防止されることにより、これら化粧皿２２とパッキン材２４との間に摺動抵抗が発生しないと共に、リング状フックピース２８は化粧料を詰めた化粧皿２２を伴わずに単独で回転されるため、リング状フックピース２８の回転に伴う回転部分を軽量化することができる。従って、蓋体１６を開放するときの操作部３４の操作力が大幅に低減され、延いては蓋体１６の開動操作性を著しく向上することができる。
【００２８】
本実施形態にあっては上記リング状フックピース２８の外周に３個の第１係合突起３０を形成した場合を開示したが、この３個に限ることなく複数個の第１係合突起３０をリング状フックピース２８の外周に等間隔に形成すればよい。勿論、該第１係合突起３０の数および位置に応じて、第２係合突起３２および小開口部１８ｅの数および位置が設定される。
【００２９】
図６から図９は本発明の第２実施形態を示し、図６は蓋体を半開した状態の斜視図、図７は蓋体を全開した状態の平面図、図８は作動状態を示す図７に対応する平面図、図９は蓋体を閉止した状態の中央断面図である。この実施形態では化粧具収納部を廃止して化粧皿２２を容器本体１２の中央部に配置すると共に、操作部をリング状フックピース２８から分離して別体として構成した点が上記実施形態と主に異なり、本実施形態は上記第１実施形態と同一構成部分に同一符号を付して重複する説明を省略して述べる。
【００３０】
即ち、この実施形態の気密化粧料容器１０ａは、図６，図７に示すように化粧皿２２を取り付ける支持部２０を容器本体１２の中央部に一体に設け、該支持部２０の上端部を中枠１８の円形開口部１８ｄに嵌合してある。そして、上記支持部２０の外側に回転自在に設けたリング状フックピース２８の外周には、上記実施形態と同様に３個の第１係合突起３０が周方向に等間隔に突設される。また、上記支持部２０に嵌合支持された上記化粧皿２２のフランジ２２ａ上面には、蓋体１６の裏側１６ａに設けたパッキン材２４のシール突起２４ａが、該蓋体１６の閉止状態で圧接される。蓋体１６の閉止状態では、蓋体１６に支柱３２ａを介して設けられた第２係合突起３２が、上記中枠１８の小開口部１８ｅから挿入されて上記第１係合突起３０にそれぞれ係合される。そして、上記リング状フックピース２８は、これから一体に突設される板ばね３６によって図中時計回り方向の付勢力が付与される。
【００３１】
上記リング状フックピース２８の外周には、これが図７に示す初期位置にある状態で前方（図中下方）側に、一対の傾斜片４０，４２が周方向に所定間隔を設けて突設され、これら傾斜片４０，４２を操作部としてのプッシュピース４４で押圧することにより、リング状フックピース２８を反時計回り方向に回転させるようになっている。上記傾斜片４０，４２はそれぞれの図中左側に斜面４０ａ，４２ａが形成され、これら斜面４０ａ，４２ａを上記プッシュピース４４で押圧するようになっている。該プッシュピース４４は容器本体１２の内方に二股となるコ字状に形成され、その中央部外側に形成された弧状部分４４ａが、容器本体１２の側壁１２ａ前面に形成した開口部１２ｄから外方に突出されると共に、二股状両端部４４ｂ，４４ｃは上記斜面４０ａ，４２ａに当接される。また、図９に示すように上記プッシュピース４４の中央部下側には係止部４４ｄが後方に突出され、該係止部４４ｄが容器本体１２の底面１２ｃに形成した凹部１２ｅに係合されることにより、該プッシュピース４４の抜け止めが行われる。
【００３２】
従って、この第２実施形態にあっては図７に示すように蓋体１６を開放してプッシュピース４４から手を離した自然状態では、リング状フックピース２８が板ばね３６の付勢力で初期位置に設定されており、第１係合突起３０は中枠１８の被覆板１８ａに形成した小開口部１８ｅの直下に位置している。この状態で蓋体１６を閉止することにより、該蓋体１６から支柱３２ａを介して突設された第２係合突起３２は、上記小開口部１８ｅから挿入されて上記第１係合突起３０に係合される。この係合状態で図９に示すように蓋体１６の閉止状態が保持され、この閉止状態で蓋体１６の裏側１６ａのパッキン材２４のシール突起２４ａが化粧皿２２のフランジ２２ａ上面に圧接されて、該化粧皿２２内の気密状態が保持される。このとき、上記第１，第２係合突起３０，３２の係合部は、上記化粧皿２２の周縁部に等間隔に複数（３箇所）配置されているため、蓋体１６の蝶番１４の精度にかかわりなく上記パッキン材２４の圧接力を保持することができる。
【００３３】
そして、閉止状態にある上記蓋体１６を開放する際には、図８に示すようにプッシュピース４４が容器本体１２から突出する弧状部分４４ａを押し込むことにより、該プッシュピース４４は全体的に後方（容器本体１２内方）に移動して二股状両端部４４ｂ，４４ｃが、リング状フックピース２８から突出する傾斜片４０，４２の斜面４０ａ，４２ａを押圧する。すると、上記傾斜片４０，４２は図中右方に逃げて、リング状フックピース２０が板ばね３６の付勢力に抗して反時計回り方向に回転され、これによって第１係合突起３０と第２係合突起３２の係合状態が離脱されるため、蓋体１６を手動で開けることができる。そして、蓋体１６を開放した後にプッシュピース４４の押圧を解除することにより、リング状フックピース２８は板ばね３６の付勢力で時計回り方向に回転して図７に示した初期位置に復帰されると共に、上記傾斜片４０，４２の斜面４０ａ，４２ａでプッシュピース４４を押し出して、弧状部分４４ａは容器本体１２から突出した初期状態に戻される。
【００３４】
従って、この実施形態にあっても容器本体１２に一体に設けられた支持部２０に化粧皿２２を取り付け、かつ、該支持部２０の外側にリング状フックピース２８を回転自在に設けてあるため、プッシュピース４４を操作して蓋体１６を開ける際にはリング状フックピース２８のみが単独で回転する。このため、化粧皿２２とパッキン材２４との相対回転がなくなって、該パッキン材２４の耐久性を向上できると共に、この相対回転がなくなることによりパッキン材２４との間に摺動抵抗が発生するのを防止し、かつ、リング状フックピース２０の回転に伴う回転部分が軽量化されて、プッシュピース４４の操作性を向上することができる。
【００３５】
図１０，図１１は本発明の第３実施形態を示し、図１０は蓋体および中蓋を全開した状態の平面図、図１１は蓋体および中蓋を閉止した状態の中央断面図である。この実施形態では上記第２実施形態の気密化粧料容器に中蓋を追加し、該中蓋によって化粧皿２２を気密に閉止した点が上記実施形態と主に異なり、本実施形態を上記第１，第２実施形態と同一構成部分に同一符号を付して重複する説明を省略して述べる。
【００３６】
即ち、この実施形態の気密化粧料容器１０ｂは、容器本体１２の後方端部に蝶番１４を介して蓋体１６が開閉自在に蝶着されると共に、容器本体１２に嵌着された中枠１８の被覆板１８ａの左方端部に、副蝶番５０を介して中蓋５２が開閉自在に蝶着される。副蝶番５０は中蓋５２の左端部中央から突設される凸部５０ａが、上記被覆板１８ａから対峙して突設される一対の軸受部５０ｂ間に嵌合されると共に、凸部５０ａの両側に突設されるピン５０ｃが、両側の軸受部５０ｂに挿入されることにより構成される。また、容器本体１２の底面１２ｃの中央部には筒状の支持部２０が一体に突設され、該支持部２０に化粧皿２２が嵌着されると共に、該支持部２０の外周にリング状フックピース２８が回転自在に取り付けられる。上記中蓋５２の裏側５２ａに、上記化粧皿２２を覆うようにパッキン材２４が嵌着される。該パッキン材２４には化粧皿２２の周縁部に対応する位置に同心円状の二重シール突起２４ｂが突設され、中蓋５２の閉止状態で該二重シール突起２４ｂが化粧皿２２のフランジ２２ａ上面に圧接されて、該化粧皿２２内が気密状態に保持される。

上記リング状フックピース２８の外周には、前方部分に１個の第１係合突起３０が突設されると共に、該第１係合突起３０の形成位置を避けて周方向に等間隔に３箇の第３係合突起５４が突設される。そして、容器本体１２の上面を覆う上記中枠１８の被覆板１８ａには、上記第１係合突起３０および上記第３係合突起５４に対応する位置にそれぞれ小開口部１８ｅが形成される。一方、上記蓋体１６の裏側１６ａの前方部分には、上記第１係合突起３０に対応した位置に支柱３２ａを介して第２係合突起３２が突設されると共に、上記中蓋５２の裏側５２ａには、上記パッキン材２４の周縁部で上記第３係合突起５４に対応した位置に支柱５６ａを介して第４係合突起５６が突設される。また、上記リング状フックピース２８の後方右側には、該リング状フックピース２０に時計回り方向の付勢力を付与するための板ばね３６が突設され、該板ばね３６の先端部は容器本体１２から突設されるピン３８に係止される。
【００３８】
また、上記リング状フックピース２８の外周の前方には、上記第２実施形態と同様に一対の傾斜片４０，４２が第１係合突起３０を挟んで対峙して突設されると共に、コ字状のプッシュピース４４の二股状両端部４４ｂ，４４ｃが傾斜片４０，４２の斜面４０ａ，４２ａに当接され、該プッシュピース４４の弧状部分４４ａが容器本体１２の開口部１２ｄから外方に突出されている。この実施形態では蓋体１６および中蓋５２の閉止状態では、これら蓋体１６と中蓋５２との間にパフ５８を収納するスペースＳが設けられている。
【００３９】
従って、この第３実施形態にあっては図１０に示すように蓋体１６を開放してプッシュピース４４から手を離した自然状態では、リング状フックピース２８が板ばね３６の付勢力で初期位置となっており、第１係合突起３０および第３係合突起５４は、中枠１８の被覆板１８ａにそれぞれ対応して形成した小開口部１８ｅの直下に位置している。この状態でまず中蓋５２を閉止することにより、該中蓋５２から支柱５６ａを介して突設された第４係合突起５６は、上記小開口部１８ｅから挿入されて上記第３係合突起５４に係合される。次に、蓋体１６を閉止することにより、該蓋体１６から支柱３２ａを介して突設された第２係合突起３２は、上記小開口部１８ｅから挿入されて上記第１係合突起３０に係合される。このように第３係合突起５４と第４係合突起５６および第１係合突起３０と第２係合突起３２がそれぞれ係合された状態で、図１１に示すように中蓋５２および蓋体１６の閉止状態が保持される。そして、上記中蓋５２が閉止されることにより、該中蓋５２の裏側５２ａに設けたパッキン材２４の二重シール突起２４ｂが、化粧皿２２のフランジ２２ａ上面に圧接されて、該化粧皿２２内の気密状態が保持される。このとき、上記第３，第４係合突起５４，５６の係合部は、上記化粧皿２２の周縁部に複数（３箇所）配置されているため、副蝶番５０や蝶番１４の精度にかかわりなく上記パッキン材２４の圧接力を保持することができる。
【００４０】
そして、閉止状態にある上記蓋体１６および上記中蓋５２を開放する際には、容器本体１２から突出するプッシュピース４４の弧状部分４４ａを押し込むことにより、該プッシュピース４４は後方に移動して二股状両端部４４ｂ，４４ｃで傾斜片４０，４２の斜面４０ａ，４２ａを押圧して、リング状フックピース２８を板ばね３６の付勢力に抗して反時計回り方向に回転させる。すると、リング状フックピース２８に形成した第１係合突起３０および第３係合突起５４は移動して、第２係合突起３２および第４係合突起５６との係合状態が離脱され、蓋体１６および中蓋５２が開動可能状態となり、この状態でまず蓋体１６を手で開いた後、次に中蓋５２を手で開けることができる。このとき、化粧皿２２のフランジ２２ａに圧接していた二重シール突起２４ｂのスプリングバックが作用して、中蓋５２の開動が容易になる。そして、上記蓋体１６および上記中蓋５２を開いた後にプッシュピース４４の押圧を解除することにより、リング状フックピース２８は板ばね３６の付勢力で時計回り方向に回転して図１０に示した初期位置に復帰されると共に、上記傾斜片４０，４２の斜面４０ａ，４２ａでプッシュピース４４を押し出して、弧状部分４４ａは容器本体１２から突出した初期状態に戻される。
【００４１】
この実施形態にあっても、容器本体１２に一体に設けられた支持部２０に化粧皿２２を取り付け、かつ、該支持部２０の外側にリング状フックピース２８を回転自在に設けてあるため、リング状フックピース２８のみが単独で回転し、化粧皿２２とパッキン材２４との相対回転がなくなって該パッキン材２４の耐久性を向上できると共に、この相対回転がなくなることによりパッキン材２４との摺動抵抗が発生せず、かつ、リング状フックピース２８の回転に伴う回転部分が軽量化されてプッシュピース４４の操作性を著しく向上することができる。
【００４２】
図１２，図１３は操作部の他の実施形態を示し、図１２は操作部を示す要部平面図、図１３は操作部の作動状態を示す要部平面図で、この実施形態を上記各実施形態と同一構成部分に同一符号を付して重複する説明を省略して述べる。
【００４３】
即ち、この実施形態では上記第２，第３実施形態と同様に、操作部としてリング状フックピース２８から分離されたプッシュピース６０を用いたもので、図１２に示すように該プッシュピース６０は、容器本体１２の側壁１２ａ前面に形成された開口部１２ｄから外方に突出する操作板６０ａと、該操作板６０ａの左端部から一体に突出されて、容器本体１２の底面１２ｃにピン６２を介して回動可能に枢支される支持片６０ｂと、上記操作板６０ａの右端部から屈曲部６０ｃを介して折り曲げ可能に突出される押圧片６０ｄとを備えて構成される。一方、リング状フックピース２８には上記押圧片６０ｄの先端部を係止する係止板２８ａが突設され、該リング状フックピース２８の初期位置では図１２に示すように上記操作片６０ａは、これの前面が容器本体１２の前面と平行となるように開口部１２ｄから突出され、かつ、上記押圧片６０ｄは先端部が右方に傾斜された状態で、該先端部が上記係止板２８ａに当接される。
【００４４】
そして、図外の蓋体または蓋体および中蓋を開放する際には、上記プッシュピース６０の操作片６０ａを押圧することにより、該操作片６０ａは図１３に示すように、支持片６０ｂを枢支するピン６２を中心に反時計回り方向に回動されると共に、押圧片６０ｄは屈曲部６０ｃが開かれつつ先端部で係止板２８ａを押圧し、これによってリング状フックピース２８は板ばね３６の付勢力に抗して反時計回り方向に回転される。このリング状フックピース２８の回転状態で図外の蓋体または蓋体および中蓋は上記各実施形態に示したように開動可能状態となり、これら蓋体または中蓋を開いた後に上記操作片６０ａの押圧を解除することにより、上記板ばね３６の付勢力でリング状フックピース２８は時計回り方向に回転して初期位置に復帰されると共に、係止板２８ａで押圧片６０ｄを押し戻して、操作片６０ａの前面が容器本体１２の前面と平行となるように該操作片６０ａを外方に突出させた初期状態になる。
【００４５】
従って、この実施形態のプッシュピース６０は、操作片６０ａを力点、支持片６０ｂのピン６２を支点、押圧片６０ｄの先端部を作用点とした「てこの原理」により、操作片６０ａに入力する押圧力を増大してリング状フックピース２８に伝達することができるため、蓋体または中蓋を開ける際の操作力をより小さくして操作部の操作性を更に向上することができる。勿論、この実施形態のプッシュピース６０を、上記各実施形態の気密化粧料容器１０，１０ａ，１０ｂに用いても良いことはいうまでもない。
【００４６】
【発明の効果】
以上説明したように本発明の請求項１に示す気密化粧料容器にあっては、蓋体に設けた第２係合突起がリング状フックピースに設けた第１係合突起に係合することで蓋体の閉止状態が保持され、この閉止状態で蓋体に設けたパッキン材が支持部に取り付けた化粧皿の周縁部上面に圧接して該化粧皿を気密状態に保持することができる。
【００４７】
また、上記第１係合突起はリング状フックピースの外周に適宜間隔をもって複数が突設されているため、第１係合突起と上記第２係合突起との複数の係合部分によって、パッキン材が化粧皿に圧接される状態を保持することができる。従って、容器本体と蓋体との蝶着部分の精度が化粧皿の密閉に影響することがなく、該蝶着部分の構成および組付け作業を簡単化することができる。
【００４８】
更に、上記リング状フックピースは容器本体から一体に設けた支持部の外側に回転自在に設けられるため、蓋体を開動するために操作部を操作して該リング状フックピースを回転する場合に、上記支持部に取り付けた化粧皿の回転を伴うことなく該リング状フックピースのみを単独で回転させることができる。従って、化粧皿は固定された状態でリング状フックピースのみが回転されるため、該化粧皿とこれの周縁部上面に圧接する上記パッキン材との擦れを無くすことができ、延いては、該パッキン材が損傷されるのを防止してこれの耐久性を向上することができる。
【００４９】
また、化粧皿とパッキン材との相対回転による摺動抵抗が無くなると共に、リング状フックピースの回転に化粧皿が伴わずに回転部分を軽量化できるため、操作部の操作力を大幅に低減して蓋体の開動操作性を著しく向上することができる。
【００５０】
また、本発明の請求項２に示す気密化粧料容器にあっては、中蓋を設けた気密化粧料容器に本発明を適用したもので、リング状フックピースの外周に設けた第１係合突起と、蓋体に設けた第２係合突起との係合状態で該蓋体の閉止状態を保持できると共に、上記リング状フックピースの外周に設けた複数の第３係合突起と、上記中蓋に設けた複数の第４係合突起との係合状態で該中蓋の閉止状態を保持することができる。そして、該中蓋の閉止状態で、中蓋の裏側に設けたパッキン材が、支持部に取り付けた化粧皿の周縁部上面に圧接されて、該化粧皿内の気密状態を保持することができる。
【００５１】
このとき、上記第３係合突起はリング状フックピースの外周に適宜間隔をもって複数が設けられ、それぞれの第３係合突起と上記第４係合突起との係合のみによって上記パッキン材の圧接状態を保持できる。このため、中蓋を設けた場合にあっても中蓋や蓋体の蝶着部分の精度に影響されることなく化粧皿の気密保持を行うことができ、該蝶着部分の構成および組付け作業を簡単化することができる。
【００５２】
また、上記リング状フックピースは容器本体から一体に設けた支持部の外側に回転自在に設けられるため、操作部を操作して該リング状フックピースを回転する場合に、該リング状フックピースは該支持部に取り付けられた化粧皿の回転を伴うことなく単独で回転されることになる。従って、化粧皿と中蓋に設けた上記パッキン材との擦れを無くして、該パッキン材の耐久性を向上することができると共に、化粧皿とパッキン材との摺動抵抗を無くし、かつ、リング状フックピースの回転に伴う回転部分を軽量化できることにより、操作部の操作力を大幅に低減して、蓋体の開動操作性を著しく向上することができるという各種優れた効果を奏する。
