【０００１】
【発明の属する技術分野】
本発明は、口紅などの棒状化粧料の繰り出しと収納とを行なうための棒状化粧料容器に関する。
【０００２】
【従来の技術】
従来より、この種の棒状化粧料容器としては、例えば、実開昭５６−６０５０７や実開昭５８−８６０１８、実開昭５８−８８９１３号公報などに記載のものが知られている。これらの棒状化粧料容器は、本体部の側面に操作部を有し、この操作部を本体部の長手方向にスライド操作すると、この操作部の動きに従って、本体部内部に収納された棒状化粧料が本体部内部で昇降する。さらに、これらの棒状化粧料容器では、上記した操作部と、本体部上部の開口部に設けられた蓋体とが接続されており、この操作部のスライドする動作によって、上記開口部を蓋体が開閉するようになっている。したがって、片手で棒状化粧料容器を保持して上記操作部をスライド操作することによって、棒状化粧料の本体部内での昇降動作と蓋体の開閉動作とを同時に行なうことができ、ワンタッチで棒状化粧料の繰り出しおよび収納を行なうことができるという、使用感に優れた棒状化粧料容器を実現している。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記した構成の各棒状化粧料容器では、棒状化粧料を繰り出して塗布するという目的のために棒状化粧料容器に要求される性能を達成するために、操作部のスライド動作を棒状化粧料に伝える機構が複雑化してしまうという問題があった。すなわち、棒状化粧料、例えば口紅などは、その使用の際に、所定量を容器から繰り出して、唇などの使用部位に押し当てて塗布を行なう。したがって、容器から繰り出される棒状化粧料は、繰り出された任意の位置において、上方から垂直に力が加えられた場合にも停止状態を保つことが要求される。操作部のスライド動作を棒状化粧料に伝える機構において、このように、棒状化粧料を、上方から加えられる力に対抗して任意の位置で停止可能とするには、従来は棒状化粧料容器内の構造の複雑化を伴っていた。
【０００４】
上記した従来知られる棒状化粧料容器の内、実開昭５６−６０５０７や実開昭５８−８８９１３号公報で示された構成では、棒状化粧料を保持する保持部材に対して操作部のスライド動作を伝える機構において、上方から加えられる力に対抗して任意の位置で棒状化粧料を停止させる構造を実現するために、上記操作部と上記保持部材とを、ベルト状の弾性部材の両端部にそれぞれ接続することで両者を連結し、このベルト状の弾性部材の中程を棒状化粧料容器の底部で湾曲させて、１８０度向きを変える状態で、上記ベルト状の弾性部材を棒状化粧料容器中に配設するという構成を採っている。このような構成とすれば、上記湾曲部に生じる抵抗（摩擦力）によって、棒状化粧料を保持する保持部材を、本体部中の任意の位置で、上方から加えられる力に対抗して停止させることが可能となる。しかし、このような構成では、ベルト状の部材として充分な強度と可撓性とを備える部材を選択し、このベルト状の部材との間で所定の摩擦力を生じる形状のベルト摺動溝を設計して本体部内に設ける必要があり、棒状化粧料容器内の構造が複雑化していた。
【０００５】
実開昭５８−８６０１８号公報で示された構成では、本体部に沿ってスライドする力が加えられる操作部と、棒状化粧料を保持する保持部とが、直接接続されており、操作部と保持部とは略一体となってスライドするため、上記したような構造の複雑化はない。しかしながら、このような構成では、保持部材を任意の位置で上方から加えられる力に対抗して停止させる構造を有していないため、棒状化粧料の塗布時には棒状化粧料が容器内に押し戻されてしまい、操作部を所定の位置で保持するための力を加える必要があり、化粧料として使い勝手の悪いものとなってしまう。保持部材が、上方から加えられる力に対抗して任意の位置で停止可能とするために、棒状化粧料を含む内部構造の外周部に、本体部の内壁を常時押圧する構造を設け、これによってスライドする上記内部構造と本体部内壁との間に所定の摩擦力を生じさせる構成も考えられるが、このような構成とすると、棒状化粧料を繰り出す操作を行なう際にもこの摩擦力の影響を受けてしまい、操作勝手の低下を招くという問題を生じる。
【０００６】
上述したように、操作部をスライド操作するワンタッチタイプの化粧料容器の他に、棒状化粧料容器としては、棒状化粧料を収納する収納筒に対して、棒状化粧料を保持する保持部材とカム機構によって係合する回転筒を回転させて、棒状化粧料を繰り出すタイプの容器がよく知られている。このような棒状化粧料容器では、上記カム機構を構成する螺旋溝の形状などにより、繰り出した棒状化粧料を任意の位置で保持することが可能となっている。しかしながら、このようなタイプの棒状化粧料容器では、上記収納筒に対して上記回転筒を回転させる動作を要するため、ワンタッチで棒状化粧料を繰り出すことができず操作性が不十分であり、また、本体部に対して棒状化粧料が回転しながら繰り出されるため、繰り出された棒状化粧料が非所望の向きとなるおそれがある。さらに、操作性を向上させるために、棒状化粧料の繰り出し動作と蓋体の開閉動作とを連動させようとすると、上記した螺旋溝を有するカム機構に蓋体を開閉するための機構を組み込む必要があり、構造が複雑化してしまうという問題を生じる。
【０００７】
本発明は、こうした問題を解決し、ワンタッチ式の棒状化粧料容器において、構造を複雑化することなく、容器から繰り出された棒状化粧料を、任意の位置で上方から加えられる力に対抗して停止可能とすることを目的としてなされ、次の構成を採った。
【０００８】
【課題を解決するための手段およびその作用・効果】
本発明の棒状化粧料容器は、棒状化粧料を昇降自在に収納する棒状化粧容器であって、
前記棒状化粧料を保持する保持部材と、
前記棒状化粧料を保持する前記保持部材を収納すると共に、一端が開口部として開口され、他端が閉じた筒状の収納孔を内部に形成し、該収納孔を形成する壁面の一部に線状を成す長穴を有する本体部と、
前記本体部の外面上に、前記長穴に沿ってスライド自在に取り付けられた操作部と、
前記操作部と前記保持部材とを前記長穴を介して連結し、前記操作部のスライドする動きに応じて前記保持部材を前記本体部内で移動させる連結部材と、
前記操作部に外力が加わっていない場合には所定の抵抗を生じて、前記本体部内での前記保持部材の移動を妨げ、前記操作部に外力が加わった場合には前記抵抗を緩和あるいは解除して、前記本体部における前記収納孔内での前記保持部材の移動を可能とする抵抗発生部材と
を備えることを要旨とする。
【０００９】
以上のように構成された本発明の棒状化粧料容器は、本体部における収納孔を形成する壁面の一部に線状を成して形成された長穴に沿ってスライド自在に取り付けられた操作部において、外力が加わらない状態となると、所定の抵抗が生じて、前記本体部内での前記保持部材の移動が妨げられる。前記操作部に外力が加わると、前記抵抗が緩和あるいは解除されて、前記本体部における前記収納孔内で、棒状化粧料を保持する保持部材が移動可能となって、棒状化粧料が昇降する。
【００１０】
このような棒状化粧料容器によれば、操作部に外力が加わらないときには、所定の抵抗によって、前記本端部内での前記保持部材の移動が妨げられるので、棒状化粧料を保持する保持部材を任意の位置で係止させることができる。したがって、任意の位置まで繰り出した棒状化粧料を、唇など目的の場所に押圧して塗布しても、棒状化粧料が棒状化粧料容器内に押し戻されることがない。さらに、このように保持部材を係止させる抵抗は、操作部に外力が加わるとき、すなわち、棒状化粧料を昇降させるために操作部をスライドさせるときには緩和あるいは解除されるため、操作部をスライドさせるときに、保持部材を係止させる抵抗の影響を受けることがなく、棒状化粧料の昇降をスムーズに行なうことができる。
【００１１】
本発明の棒状化粧料容器において、
前記抵抗発生部材は、
前記操作部に対して加えられる外力に対抗する方向に働く押圧力を、前記操作部に対して付与するバネを備え、
前記操作部に対して外力が加えられないときには、前記バネから前記操作部に対して働く前記押圧力によって、前記操作部を前記本体部に係合させて、前記収納構内の任意の位置で前記保持部材を係止させ、
前記操作部に対して外力が加えられたときには、前記バネから加えられる前記押圧力に対抗して働く前記外力によって、前記操作部と前記本体部との係合を解除する
構成も好適である。
【００１２】
このような構成とすれば、操作部材に外力が加えられないときには前記操作部を前記本体部に係合させ、前記操作部に対して外力他加えられるときには前記操作部と前記本体部との係合を解除する構成を、バネという簡単な部材を設けることで実現することができる。
【００１３】
また、本発明の棒状化粧料容器において、
棒状化粧料の少なくとも先端部を収納し、前記収納孔内に収納されるスリーブをさらに備え、
前記操作部がスライドする動きによって、前記保持部材に加えて前記スリーブを前記収納孔内でスライドさせ、少なくとも前記スリーブが前記開口部に達するまでは該スリーブを前記棒状化粧料に先行して繰り出し、最終的には前記スリーブおよび前記開口部から棒状化粧料の先端部を突出させる位置まで繰り出す
こととしてもよい。
【００１４】
このような構成とすれば、棒状化粧料が本体部に収納されているときには、棒状化粧料の少なくとも先端部は前記スリーブに収納されているため、携帯時などに棒状化粧料容器に衝撃が加わっても、棒状化粧料容器内で棒状化粧料の先端部が損傷を受けてしまうことがない。また、少なくとも前記スリーブが前記開口部に達するまでは該スリーブによって棒状化粧料の先端が保護されるため、棒状化粧料の先端が本体部およびその開口部によって損傷を受けてしまうことがない。
【００１５】
このような棒状化粧料容器において、
第１案内部と第２案内部とをさらに備え、
前記第１案内部は、
前記本体部および前記スリーブの内の一方に形成された係合部と、
前記本体部および前記スリーブの内の他方に形成され、前記係合部を係合させると共に、前記他方の長手方向に沿って形成される直線部と、該直線部に連続して形成されるカム部とからなる係合受け部とを備え、
前記操作部がスライドする動きによって、前記係合部を前記係合受け部の前記直線部に沿って摺動させることで、前記スリーブを前記長手方向にスライドさせて繰り出し、その後、前記係合部を前記カム部に導いて前記スリーブを所定の方向に回転させた後、前記係合部を前記カム部の端部で係止させることによって、その動きを規制すると共に、
前記第２案内部は、
前記スリーブの回転と共に前記スリーブの動きが規制された後、前記操作部の動きに従って、前記保持部材をスライドさせるように構成された
こととしてもよい。
【００１６】
このような棒状化粧料容器によれば、前記連結部材を介して伝えられた前記操作部のスライドする動きは、前記第１案内部のために前記スリーブを動かし、前記スリーブの動きが規制された後は、前記第２案内部のために前記保持部材をスライドさせる。従って、まずスリーブをスライドさせ、その後保持部をスライドさせることによって、最終的にスリーブおよび本体部の開口部から棒状化粧料を繰り出すことができる。ここで、上記係合受け部の長手方向の長さを所定の長さに設定することによって、少なくとも前記スリーブが前記開口部に達するまでは該スリーブを前記棒状化粧料に先行して繰り出す動作を実現することができる。
【００１７】
さらに、本発明の棒状化粧料容器において、
前記連結部材は、前記操作部と前記保持部材とを一体的に連結し、スライドする前記操作部と一体的に前記保持部材を前記収納孔内で移動させる
構成も好適である。
【００１８】
このような構成とすれば、操作部をスライドさせる方向と、棒状化粧料が昇降する方向とが一致するため、棒状化粧料の繰り出し動作の際の使用感が向上する。また、前記操作部と前記保持部材とを一体的に連結することによって、前記連結部材の構成を簡素化することができる。
【００１９】
また、本発明の棒状化粧料容器は、
前記本体部における前記開口部の周辺部において、所定の軸支部によって軸支され、該開口部を開閉自在な蓋体をさらに備え、
前記操作部のスライド操作により、前記棒状化粧料より先に繰り出される前記スリーブの先端部で、前記蓋体を押圧して開かせる
こととしてもよい。
【００２０】
このような場合には、棒状化粧料よりも先行して本体部の開口部に達するスリーブによって蓋体が押し開けられるため、前記操作部に対する所定の操作を行なうだけで、棒状化粧料の繰り出しと共に蓋体を開ける操作も同時に行なうことができる。また、棒状化粧料の先端部が蓋体によって損傷を受けてしまうこともない。
【００２１】
さらに、このような棒状化粧料容器において、
前記蓋体は、前記軸支部に第１突起を備え、
前記スリーブは、上端部において前記第１突起と係合可能な第２突起を備え、
前記操作部のスライド操作により前記スリーブが下降する際に、前記第２突起が前記第１突起と係合することによって前記軸支部を回動させ、前記蓋体を前記開口部において閉状態とする
こととしてもよい。
【００２２】
このような場合には、下降するスリーブが備える第２突起が、蓋体が備える第１突起と係合することによって、前記蓋体の前記軸支部が回動し、前記蓋体が閉状態となるため、前記操作部をスライドさせる操作を行なうだけで、棒状化粧料の収納と共に蓋体を閉じる操作も同時に行なうことができる。
【００２３】
また、本発明の棒状化粧料容器は、
前記棒状化粧料の少なくとも先端部を収納し、前記収納孔内に収納されるスリーブと、
前記本体部における前記開口部の周辺部において、所定の軸支部によって軸支され、該開口部を開閉自在な蓋体と、
前記スリーブがスライドする動きに応じて動く可動部材とをさらに備え、
前記蓋体は、前記可動部材と係合する連携部を有し、前記スリーブがスライドして前記収納孔内に収納されるときには、前記可動部材と前記連携部との係合関係によって、前記蓋体が前記開口部において閉状態となる
こととしてもよい。
【００２４】
このような構成によれば、前記スリーブがスライドして前記収納孔内に収納されるときには、前記スリーブがスライドする動きに応じて動く可動部材と、前記蓋体が有する連携部との係合関係によって、前記蓋体が前記開口部において閉状態となるため、前記操作部をスライドさせる操作を行なうだけで、棒状化粧料の収納と共に蓋体を閉じる操作も同時に行なうことができる。なお、前記スリーブがスライドする動きに応じて動く可動部材によって、蓋体を閉じる動作に加えて、蓋体を開ける動作も行なうこととしてもよい。
【００２５】
【発明の実施の形態】
以上説明した本発明の構成・作用を一層明らかにするために、以下本発明の実施の形態を実施例に基づき説明する。以下に説明する実施例では、本発明の棒状化粧料容器として、棒状化粧料である口紅を収納する口紅容器を挙げる。
【００２６】
図１は、口紅Ｋを出没自在に収納する口紅容器１０の外観を示し、図１（Ａ）、（Ｂ）、（Ｃ）は、正面、背面および側面をそれぞれ示す外観図であり、図１（Ｄ）は口紅Ｋを繰り出した状態の側面を示す外観図である。また、図２は、図１（Ｂ）の２−２線に沿った拡大断面図である。図３は、口紅容器１０の一部の分解斜視図であり、図４は、口紅容器１０を構成する部材の内、図３に示さなかった部材の斜視図である。最初に、図１ないし図４に基づいて、口紅容器１０の構成の概略について説明し、続いて口紅容器１０において繰り出した口紅Ｋを任意の位置で保持するための機構について説明し、その後、口紅容器１０において口紅Ｋの繰り出しを実現する構造とその動作について説明する。
【００２７】
口紅容器１０は、図１ないし図４に示すように、収納孔２０ａを有する筒状の本体部２０と、本体部２０に取り付けられた蓋体３０と、収納孔２０ａ内にスライド可能に収納されたスリーブ４０と、スリーブ４０内に内装され口紅Ｋを保持する保持部５０と、口紅Ｋの繰り出しおよび収納のために外部から加えられる操作力を受ける操作部６４を有する操作部材６２とを備えている。また、口紅容器１０は、これらの部材の構造によって実現される機構として、口紅容器１０から繰り出した口紅Ｋを任意の位置で保持するための保持機構と、口紅Ｋの繰り出し動作に関わる昇降機構と、口紅Ｋを口紅容器１０内に収納する際に自動的に蓋体３０を閉じるための蓋閉じ機構とをさらに備えている。本実施例の口紅容器１０では、上記操作部６４を本体部２０に対してスライドさせることによって、口紅Ｋの繰り出しおよび収納を行なうことができる。
【００２８】
上記本体部２０は、その長手方向に収納孔２０ａを形成しており、この収納孔２０ａを略対称に形成する一対の枠体２１ａおよび２１ｂを超音波溶接法により接合して構成されている。図３には枠体２１ｂを、図４には枠体２１ａを示した。なお、本体部２０は、超音波溶接法で接合するほか、接着剤で接合など他の方法で接合することとしてもよい。本体部２０が備える収納孔２０ａは、その一端は閉じた形状となって本体部２０の底面を形成している。また、収納孔２０ａの他端は開口部２２において開口している。以後、本実施例の口紅容器１０において、開口部２２側を上方向、反対側を下方向と呼ぶことにする。
【００２９】
本体部２０は、開口部２２の周辺部が傾斜した形状に形成されている。開口部２２の近傍であって枠体２１ａと２１ｂとのつなぎ目の位置において、傾斜面の下部側には後述する蓋体３０の開閉に関わる軸３１ｂが設けられている。さらに、本体部２０の側部には、上記した軸３１ｂの近傍から本体部２０の底面付近にわたって、すなわち本体部２０の長手方向に沿って、係合板８２が配設されている（図３参照）。係合板８２は、その内側（収納孔２０ａに向く側）に凹凸面８４を備えている。図５は、係合板８２の外観を表わす説明図である。図５（Ａ）は、係合板８２を凹凸面８４側から見た様子を表わし、図５（Ｂ）は、図５（Ａ）における矢印Ｂ側から係合板８２を見た様子を表わす。図５に示すように、係合板８２は、凹凸面８４において、本体部２０の長手方向と垂直な向きの細かい線状の凸構造を上端部から下端部まで形成している。ここで係合板８２は、接着剤によって枠体２１ｂに接着されている。この係合板８２は、既述した保持機構に関わるものであり、保持機構については後に詳しく説明する。また、本体部２０を構成する枠体２１ａにおいて、収納孔２０ａの内壁には第１突子７４が形成されている（図４参照）。この第１突子７４は、収納孔２０ａ内でスライドするスリーブ４０を導き、あるいはこのスリーブ４０の動きを規制するために働き、既述した昇降機構に関わるものであり、詳しい説明は後述する。
【００３０】
蓋体３０は、上記開口部２２を開閉する部材である。蓋体３０は、貫通孔を備えた突起部３１ａを周辺部の所定位置に有し、この突起部３１ａの貫通孔に既述した軸３１ｂを嵌合させることによってヒンジ３１を形成している。蓋体３０は、このヒンジ３１によって支持されることで開口部２２を開閉自在となっている。この蓋体３０は、後述するように口紅Ｋの繰り出し時にはスリーブ４０の先端部によって押し開けられる。また、ヒンジ３１は蓋体３０の開閉動作時には所定の抵抗が生じる様に形成されているため、指で蓋体３０に対して開き方向へ力を加えることによって、この蓋体３０を自由な角度に開いて係止させることもできる。
【００３１】
蓋体３０の内側には環状凸部３２が形成されており、この環状凸部３２は、蓋体３０が閉じられたときには開口部２２の内側に嵌まり込む。また、上記突起部３１ａは、その端部に第３突子３４を備えている。この第３突子３４は、スリーブ４０が備える後述する第４突子４２と共に、既述した蓋閉じ機構に関わるものであり、後に詳しく説明する。
【００３２】
スリーブ４０は、収納孔２０ａ内においてその上下方向に摺動自在に収納されており、その内部には、口紅Ｋを保持する保持部５０を同じく上下方向に摺動可能に収納している。このスリーブ４０は、保持部５０に保持された口紅Ｋの全長を収納可能な長さを有している。また、スリーブ４０および口紅Ｋの上端面は傾斜しており、この傾斜面は開口部２２における傾斜面と略平行に形成されている。スリーブ４０、保持部５０および口紅Ｋの横断面は、いずれも略円形を成している。ここで、スリーブ４０において傾斜した上端面付近の所定の位置には、上記蓋閉じ機構に関わる第４突子４２が設けられている（図２，図３参照）。保持部５０は、口紅Ｋを下方より支持しており、口紅Ｋの下端部が嵌合されている。
【００３３】
図６は、スリーブ４０を異なる３方向から見た外観を示し、図７は、スリーブ４０から保持部５０と操作部材６２とを取り外した様子を表わす分解斜視図であり、図８は、操作部材６２における異なる２方向からの側面の様子を表わす説明図である。なお、図８（Ｂ）は、図８（Ａ）における矢印Ｂの方向から操作部材６２を見た様子を表わす。スリーブ４０には、カム溝７２とガイド溝７８とが形成されており、保持部５０には、操作部材６２が係合する係合穴５２が設けられている。操作部材６２は、口紅Ｋを繰り出すために外部から加えられる力を受けるための操作部６４と、上述した係合穴５２に貫通して係合する第２突子６６とを備えている。ここで、操作部材６２は、上記操作部６４と第２突子６６とを連結する領域がＵ字状に折れ曲がって形成されており、このＵ字状の構造において所定の弾性を実現し、バネ部６８を形成している。また、操作部材６２は、操作部６４の裏側に、本体部２０が備える既述した係合板８２を挟み込んでこれと係合する凹部６５を形成している。操作部材６２において、この凹部６５を形成する表面の内、係合板８２の凹凸面８４と当接する側の面には、３つの係合突起６７が形成されている。上記したカム溝７２、ガイド溝７８、係合穴５２および第２突子６６等の構造は、口紅Ｋの繰り出しの動作に関わるものであり、詳しい説明は後述する。また、バネ部６８および係合突起６７は、口紅容器１０から繰り出された口紅Ｋを任意の位置で係止させる動作に関するものであり、これについても詳しい説明は後述する。
【００３４】
つぎに、口紅容器１０において繰り出した口紅Ｋを任意の位置で保持するための機構である保持機構について説明する。この保持機構は、既述した係合板８２と、操作部材６２と、保持部５０とによって実現される。まず、口紅Ｋを保持する保持部５０が任意の位置で係止するときの保持機構の動作について説明し、続いて、口紅Ｋを繰り出しあるいは収納しようとして、口紅Ｋを保持する保持部５０係止状態を解除するときの保持機構の動作について説明する。
【００３５】
図９は、上記保持機構を構成する操作部材６２と係合板８２との係合関係を模式的に表わす説明図である。図９（Ａ）は、保持部５０が任意の位置で係止するときの状態を表わし、図９（Ｂ）は、保持部５０の係止状態が解除されたときの状態を表わす。操作部材６２は、既述したように、第２突子６６を保持部５０の係合穴５２に貫通させることによって保持部５０内と係合しており、Ｕ字型のバネ部６８を構成する部分を保持部５０の下部領域内に収納された状態で、口紅容器１０内に配設される（図２、図７参照）。このとき、バネ部６８において、操作部６４と第２突子６６とを互いに遠ざけようとする方向（図９（Ａ）の矢印の方向）の力を生じるように、操作部材６２は口紅容器１０内に配設される。
【００３６】
操作部材６２のバネ部６８においてこのような力が生じると、操作部材６２の凹部６５を形成する面であって、３つの係合突起６７を有する面が、本体部２０に取り付けられた係合板８２の凹凸面８４に向かって押圧される。従って、３つの係合突起６７と凹凸面８４上に形成された凹凸構造とが係合する。そのため、口紅Ｋに上下方向の外力が加えられても、３つの係合突起６７と凹凸面８４上の凹凸構造との係合関係によって、操作部材６２が係合板８２に対して所定の位置で係止しているため、口紅Ｋが上記外力によって移動することがない。
【００３７】
口紅Ｋの繰り出しあるいは収納を行なう際には、使用者は、口紅容器Ｋを保持しながら、操作部６４を本体部２０の外壁に沿ってスライドさせる。このような操作を行なうと、操作部６４では、本体部２０の外壁に沿って上下方向に働く力と共に、操作部６４を本体部２０に対して垂直に押圧する力が働く（図９（Ｂ）の矢印の方向）。操作部６４を本体部２０に対して垂直に押圧するこのような力は、バネ部６８によって生じる操作部６４と第２突子６６とを遠ざけようとする力とは逆向きの力であり、これによって、既述した係合板の凹凸面８４と、３つの係合突起６７との間の係合状態が解除される。従って、口紅Ｋを保持する保持部５０が所定の位置で係止された状態が解除され、保持部５０は、係合穴５２を介して連結された操作部６４のスライド動作に従って上下動し、これによって口紅Ｋが昇降する。
【００３８】
なお、保持機構によって実現される保持部５０を係止させる力は、本体部２０から繰り出した口紅Ｋを唇に押圧して塗布する際に、保持部５０を下方に押し戻す方向に働く力に対抗して、口紅Ｋが所定量繰り出された位置で保持部５０を係止させた状態を維持するのに充分なものであればよい。保持部５０を係止させるためのこのような力を実現可能であって、口紅Ｋを昇降させるために操作部６４に加えられる力で容易にこの係合状態が解除されるように、凹凸面８４上の凹凸構造の形状や係合突起６７の大きさ、あるいはバネ部６８の構造を設定すればよい。
【００３９】
次に、口紅容器１０において口紅Ｋの繰り出しを実現するための昇降機構について説明する。昇降機構は、操作部６４および第２突子６６を備える操作部材６２と、カム溝７２およびガイド溝７８を備えるスリーブ４０と、第１突子７４を備える枠体２１ｂと、係合穴５２を備える保持部５０等によって実現される。昇降機構は、操作部６４に加えられた操作力をスリーブ４０および保持部５０に伝えることによって、スリーブ４０と口紅Ｋを保持する保持部５０とを収納孔２０ａ内において昇降させる。以下、昇降機構を構成する各部材の構造と、口紅Ｋの繰り出し操作時における動作について説明する。
【００４０】
操作部６４は、口紅Ｋを出没させるために指による操作を行なう対象となる部材である。この操作部６４は、本体部２０の側部において長手方向に形成された操作溝２０ｄ（図３および４参照）に沿ってスライド可能に配設されている。操作溝２０ｄは、枠体２１ａおよび２１ｂのつなぎ目において、ヒンジ３１側の側面に設けられている。
【００４１】
また、この操作部６４を備える操作部材６２は、既述したように、端部に設けられた第２突子６６において保持部５０に接続しているため、操作部材６２と保持部５０とは一体となって移動し、操作部６４をスライドさせることによって口紅Ｋを昇降させることができる。口紅Ｋが口紅容器１０内に完全に収納されているときには、操作部６４は操作溝２０ｄの下端部に位置し（図１の（Ｂ）および（Ｃ）に示す位置）、その操作部６４を操作溝２０ｄの上端部（図１の（Ｄ）に示す位置）に向かって摺動させるにつれて口紅Ｋが繰り出される。このように第２突子６６によって保持部５０に接続する操作部材６２は、口紅容器１０においては、保持部５０と一体になった状態で、バネ部６８から第２突子６６までの構造が、スリーブ４０内に収納される。
【００４２】
既述したように、スリーブ４０にはカム溝７２とガイド溝７８とが形成されている。ガイド溝７８は、スリーブ４０の長手方向に形成された孔構造であり、その下端部において略直角に曲がる水平部７８ａを形成している（図６参照）。スリーブ４０内に、上述したように、保持部５０および操作部材６２の一部（第２突子６６からバネ部６８までの構造）を内装したときには、操作部材６２の残りの領域は、このガイド溝７８を貫通してスリーブ４０外に突出する。以下、操作部材６２においてガイド溝７８と係合する場所であって、操作部６４とバネ部６８とを接続する領域を、係合軸６９と呼ぶ（図８参照）。
【００４３】
ここで、上記係合軸６９が、ガイド溝７８の水平部７８ａと係合しているときには、操作部６４の動きは、保持部５０に加えてスリーブ４０にも伝達される。したがってこのような場合には、操作部６４を下端側から上端側に向かってスライドさせると、この動きに応じてスリーブ４０と保持部５０とが一体となって上昇する。従って、スリーブ４０内の口紅Ｋはスリーブ４０と共に移動し、スリーブ４０に対して相対的に移動することがない。また、スリーブ４０が所定の位置に係止した状態で、操作部材６２の係合軸６９が水平部７８ａから開放されると、保持部５０は係止したスリーブ４０内を摺動して上昇するようになる。従って、スリーブ４０内の口紅Ｋは、スリーブ４０に対して相対的に上昇する。
【００４４】
また、スリーブ４０において、ガイド溝７８の下端部には、切れ込み部７８ｃが設けられている（図６（Ａ）参照）。この切れ込み部７８ｃは、口紅容器１０の組み立ての際に、係合穴５２において操作部材６２と接続する保持部５０をスリーブ４０内に収納する動作を可能にする。すなわち、操作部材６２と一体となった保持部５０をスリーブ４０内に押し込むと、操作部材６２の係合軸６９は、切れ込み部７８ｃに導かれてガイド溝７８にはまり込む。
【００４５】
スリーブ４０においてガイド溝７８とともに設けられたカム溝７２は、スリーブ４０の長手方向に形成された直線部７２ｂと、直線部７２ｂの下端部において一方向（隣接するガイド溝７８から離れる方向）に屈曲するカム部７２ａとからなる（図３，図７参照）。このカム溝７２は、枠体２１ａが備える既述した第１突子７４（図４参照）と係合する。操作部６４の動きが、操作部材６２とガイド溝７８の水平部７８ａとが係合することによってスリーブ４０に伝えられたときには、スリーブ４０は、カム溝７２において第１突子７４と係合する位置を移動させながら収納孔２０ａ内を昇降する。スリーブ４０が上昇し、第１突子７４の係合位置が直線部７２ｂからカム部７２ａに移行すると、スリーブ４０はカム部７２ａの形状に従ってその屈曲方向にわずかに回転する。第１突子７４がカム部７２ａの端部に達してその端部で係止すると、スリーブ４０の上昇もまた停止する。このカム部７２ａは、スリーブ４０を上記したように回転させることによって、操作部材６２の係合軸６９をガイド溝７８の水平部７８ａから開放し、この係合軸６９を、ガイド溝７８の長手方向に沿って移動可能にすると共に、スリーブ４０を所定の位置で係止させるための構造である。
【００４６】
以下に、操作部６４を操作して口紅Ｋを繰り出す際の昇降機構の動作について説明する。図１０は口紅Ｋの繰り出し操作の際の昇降機構の動作を説明する説明図である。図１０は、第１突子７４とカム溝７２との係合および係合軸６９とガイド溝７８との係合の状態を示すと共に、各状態でのスリーブ４０および化粧料Ｋの繰り出しの状態と操作部６４の位置とを表わす。なお図１０においては、スリーブ４０の回転する様子を平面的な移動に置き換えて表わした。
【００４７】
いま、蓋体３０が閉じて、口紅Ｋが本体部１２０内に完全に収納されている状態にあるとする（図１（Ｂ）の状態）。この状態では、操作部６４が操作溝２０ｄの下端に位置し、また、本体部内壁に形成された第１突子７４は、スリーブ４０のカム溝７２の上端部に係合し、さらに操作部材６２の係合軸６９は、スリーブ１４０に形成されたガイド溝７８の下端部に設けられた水平部７８ａに係合している（図１０（Ａ）の状態）。
【００４８】
この状態から、操作部６４を指で操作して上方へスライドさせると、操作部材６２全体が、保持部５０と一体となって上昇する。操作部材６２の係合軸６９は、スリーブ４０に形成されたガイド溝７８の水平部７８ａに係合しているため、上記操作部材６２と保持部５０とに加え、スリーブ４０も一体となって上昇する。操作部６４を所定量スライドさせると、上昇したスリーブ４０の先端部が蓋体３０の環状凸部３２に当接する。さらに操作部６４を上方にスライドさせると、スリーブ４０の先端部は、蓋体３０を押し開けて環状凸部３２を越えて上昇し、開口部２２から本体部２０外に繰り出される。
【００４９】
このように操作部６４を上方へスライドさせると、第１突子７４は、カム溝７２の直線部７２ｂに沿って直線部７２ｂの下方に導かれ、やがて、カム溝７２の下端部に形成されたカム部７２ａに達する。このカム部７２ａは既述した所定の方向に屈曲しているため、第１突子７４がカム部７２ａ内を導かれるときスリーブ４０はわずかに回転する。このスリーブ４０のわずかな回転により、操作部材６２の係合軸６９は、ガイド溝７８の水平部７８ａから開放される（図１０（Ｂ）の状態）。
【００５０】
この後さらに操作部６４を上方にスライドさせると、本体部２０の内壁面に形成された第１突子７４は、スリーブ４０に形成されたカム溝７２の下端部に係合しているため、スリーブ４０は係止した状態を保つ。ここで操作部材６２の係合軸６９は水平部７８ａから開放されているため、操作部６４がスライドする動きによって、操作部材６２と接続する保持部５０だけが上昇を続ける。これにより、保持部５０と一体の口紅Ｋが上昇し（図１０では口紅Ｋと保持部５０とを併せてＫと表示している）、口紅Ｋの上端部が開口部２２およびスリーブ４０の先端部から繰り出される（図１０（Ｃ）の状態、図１（Ｄ）を参照）。この状態において、口紅Ｋの使用が可能になる。
【００５１】
逆に、口紅Ｋが開口部２２およびスリーブ４０の先端部から繰り出された状態において操作部６４を下方へスライドさせると、上記の説明とは逆の過程を経る。すなわち、口紅Ｋおよび保持部５０が下降してスリーブ４０内に収納され、その後スリーブ４０も本体部２０内部に完全に収納される。ここで、スリーブ４０が本体部２０内に収納されるときには、既述した蓋閉じ機構によって蓋体３０を閉じる動作が行なわれる。
【００５２】
以下に、口紅Ｋを口紅容器１０内に収納するときに実行される蓋閉じ機構について説明する。蓋閉じ機構は、蓋体３０およびスリーブ４０等によって実現される。既述したように、蓋体３０には第３突子３４が設けられ、スリーブ４０には第４突子４２が設けられている。操作部６４を操作溝２０ｄに沿って下方にスライドさせ、口紅Ｋを収納する動作を行なうと、口紅Ｋを収納したスリーブ４０が本体部２０内に収納されるときに、スリーブ４０に備えられた第４突子４２が、蓋体３０の第３突子３４に係合し、第３突子３４には下方向の力が働く。第３突子３４にこのような力が働くと、蓋体３０において、本体部２０に設けられた軸３１ｂに嵌合する部分が支点として、第３突子３４が力点として働き、蓋体３０は開口部２２を閉じる方向に回動する。口紅Ｋを収納するスリーブ４０が完全に本体部２０内に収納された後、蓋体３０が本体部２０の上端部に当接して蓋体３０が閉じられると、口紅容器１０は最初の状態（図１（Ａ）ないし（Ｃ）の状態）に戻る。
【００５３】
以上のように構成された本実施例の口紅容器１０によれば、片手で操作部６４を操作することによって、ワンタッチで口紅Ｋを使用可能な状態に準備できると共に、所望の位置まで繰り出した口紅Ｋを、直接に唇上に塗布する動作を行なっても、口紅Ｋが口紅容器１０内に押し戻されてしまうことがない。すなわち、操作部６４に対して操作力が加えられていないときには、操作部材６２が係合板８２に係合するため、上下方向に加えられる力に対抗して、口紅Ｋを保持する保持部５０を任意の位置で保持することができる。したがって、口紅を塗布する動作に関する使用勝手を向上させることができる。
【００５４】
このような口紅Ｋの保持に関わる操作部材６２と係合板８２との係合関係は、口紅Ｋが昇降する方向とは垂直な方向に働く力であって、操作部６４を口紅容器１０の外壁に向かって押圧する力によって解除される。口紅Ｋを昇降させるときには、指を操作部６４に押圧してこの操作部６４をスライドさせるため、このような力が働く。したがって、操作部６４をスライドさせて口紅Ｋを昇降させる際には、操作部材６２と係合板８２との係合関係の影響を受けることがなく、口紅Ｋの昇降をスムーズに行なうことができる。
【００５５】
また、上記した口紅Ｋを任意の位置で保持するための保持機構は、操作部６４を備える操作部材６２と、本体部２０に取り付けられた係合板８２との間の係合関係によって実現されるため、保持機構を設けることによって、口紅容器１０全体の構造が複雑化してしまうことがない。特に本実施例では、操作部６４を有する操作部材６２を保持部５０に固着して、両者を一体で昇降させる構成としており、このように簡単な構成によって、操作部６４の動きが保持部５０に伝達可能となっている。
【００５６】
本実施例の口紅容器１０では、保持機構において係合板８２に操作部材６２を係合させる力（操作部材６２が有する３つの係合突起６７を、係合板８２の凹凸面８４に押圧する力）は、操作部材６２のバネ部６８が示す弾力によって実現している。したがって、操作部材６２は、既述したＵ字型のバネ部６８を形成したときに、このバネ部６８が充分な弾性を示すことが可能となる樹脂などの部材によって形成すればよい。また、本体部２０，蓋体３０，スリーブ４０，保持部５０は、上述した動作を実現するために充分な強度を有する部材、例えば金属や樹脂等によって形成すればよい。
【００５７】
ここで、本実施例の口紅容器１０では、操作部材６２の一端に操作部６４を設け、他端に保持部５０と係合する第２突子６６を設けて、操作部６４と口紅Ｋを保持する保持部５０とが一体となって昇降する構成としたが、操作部６４と保持部５０の間にベルトなど他の部材を介在させることとしてもよい。すなわち、操作部６４の動きを保持部５０に伝達して、操作部６４がスライドする動きに応じて保持部５０を昇降させる機構は、異なる機構であっても構わない。このような場合にも、上記実施例と同様の保持機構を設けることによって、口紅容器から繰り出した口紅を塗布する際に、口紅が口紅容器内に押し戻されてしまうのを防ぐことができる。
【００５８】
なお、本実施例では、操作部６４と一体で形成された操作部材６２の一部をＵ字型に形成して、バネ部６８とすることによって、上記した押圧力を実現しているが、他の構成によってこの押圧力を得ることとしてもよい。他の構成の一例として、上記実施例の操作部材６２に代えて用いることができる操作部材１６２の構成を図１１に示す。図１１の操作部材１６２において、上記実施例の操作部材６２と共通する構成については同じ番号を付して説明は省略する。図１１の操作部材１６２は、操作部６４を有する第１部材１６１と、第２突子６６を有する第２部材１６３の二つの部材に分かれており、これら第１部材１６１と第２部材１６３の間には、コイルバネからなるバネ部１６８が配設されている。このような操作部材１６２を、操作部材６２に代えて口紅容器１０の所定の位置に組み込むと、第２突子６６と係合する保持部５０の係合穴５２と、凹部６５と係合する係合板８２との位置関係とによって、バネ部１６８において所定の弾性力が生じ、第１部材１６１の３つの係合突起６７は、係合板８２の凹凸面８４に向かって押圧される。
【００５９】
また、本実施例では、昇降機構を実現するために、本体部２０の内壁面側に第１突子７４を、スリーブ４０側にカム溝７２を設け、両者の係合関係によってスリーブ４０の動きを規制したが、これらの係合関係において、両者の凹凸を逆に形成することとしてもよい。すなわち、本体部２０の内壁面側に突子を設け、スリーブ４０側にこの突子と係合するカム溝を設けることとしてもよい。このような構成の口紅容器を口紅容器１１０として以下に説明する。口紅容器１１０において、口紅容器１０と共通する部材には同じ番号を付し、詳しい説明は省略する。口紅容器１１０は、既述した口紅容器１０と同様の枠体２１ｂ，保持部５０および操作部材６２を有する。また、第１突子７４に代えてカム溝１７２を有する枠体１２１ａと、カム溝７２に代えて第１突子１７４を有するスリーブ１４０を備えている。枠体１２１ａの構成を図１２に示し、保持部５０および操作部材６２をスリーブ１４０からはずした様子を表わす分解斜視図を図１３に示す。
【００６０】
枠体１２１ａの内壁に形成されたカム溝１７２は、スリーブ１４０に形成された第１突子１７４が係合する。操作部６４の動きが係合軸６９を介してスリーブ１４０に伝えられたときには、スリーブ１４０は、第１突子１７４をカム溝１７２に沿って摺動させながら収納孔２０ａ内を昇降する。カム溝１７２は、収納孔２０ａの長手方向に形成された直線部１７２ｂと、直線部１７２ｂの上端部において一方向（ヒンジ１３１側）に屈曲するカム部１７２ａとからなる（図１２参照）。スリーブ１４０が上昇し、第１突子１７４の係合位置が直線部１７２ｂからカム部１７２ａに移行すると、スリーブ１４０はカム部１７２ａの形状に従ってその屈曲方向にわずかに回転する。第１突子１７４がカム部１７２ａの端部に達してその端部で係止すると、スリーブ１４０の上昇もまた停止する。このカム部１７２ａは、スリーブ１４０を回転させることによって、既述した実施例と同様に係合軸６９を水平部７８ａから開放し、この係合軸６９をガイド溝７８に沿ってスライド可能にすると共に、スリーブ１４０を所定の位置で係止させる。
【００６１】
以上説明した口紅容器１１０においても、既述した実施例の口紅容器１０と同様に口紅の繰り出し動作を実現することができ、操作部材６２と係合板８２との間の係合関係によって実現される保持機構を備えることによって、繰り出した口紅を塗布する動作を行なう際に、口紅が口紅容器１１０内に押し戻されるのを防ぐことができる。
【００６２】
また、既述した実施例では、蓋体３０に第３突子３４を設け、スリーブ４０に第４突子４２を設けて、スリーブ４０が本体部２０内に収納されるときに両者を係合させることによって、口紅Ｋの収納時に蓋体３０を閉じる動作を同時に行なっているため、口紅の繰り出し，塗布，収納という一連の動作を行なう際の操作性が向上し、これらの動作をワンタッチで（片手で口紅容器を保持しつつ指一本の操作で）行なうことが可能となっている。ここで、蓋体３０の開閉に関わる機構を他の構成によって実現することとしてもよい。例えば、スリーブが所定の位置に移動するまではスリーブと一体で昇降する所定の部材を設け、この所定の部材と蓋体とを接続してこの部材によって蓋体を開閉することとしてもよい。すなわち、口紅がスリーブを超えて繰り出されるまでは上記所定の部材はスリーブと共に昇降する構成とし、スリーブの上昇と共にこの所定の部材によって蓋体を押圧して開状態とし、また、スリーブの下降と共にこの所定の部材によって蓋体を引き下げて閉状態とする。このような構成とすることによって、上記実施例と同様に、操作部をスライドさせる動作によって、蓋体を有する口紅容器からの口紅の繰り出しおよび収納をワンタッチで行なうことが可能となる。
【００６３】
既述した実施例の口紅容器では、保持部は皿状の形状を有しており、口紅Ｋをその下端部から支え、この保持部に口紅Ｋの下端部を嵌合することによって口紅Ｋを保持部に対して固定しているが、保持部は他の形状を有するものであっても構わない。例えば、円形の枠組として形成された保持部によって、口紅Ｋの下部においてその側面を挟み込んで支えることとしても良く、口紅Ｋを固定可能であって、操作部の動きを伝える部材と接続可能であれば良い。
【００６４】
また、上記実施例では、口紅容器の開口部において別体の蓋体を取り付け、上昇するスリーブによってこの蓋体を押し開ける構成としたが、蓋体を廃止して、操作部材の端部をシャッタとして構成してもよい。このような場合には、操作部のスライド操作に伴ってシャッタが開口部を開閉するため、別部材からなる蓋体が不要となる。
【００６５】
上記実施例で蓋体と本体部との接続部位に設けられたヒンジにおいて、蓋体に対して閉じ方向へばね力を付勢する構成を加えることとしても良い。このような構成とすれば、実施例における蓋閉じ機構を設けることなく、口紅Ｋの繰り出しから収納までをワンタッチで行なうことが可能となる。この場合には、ベルトの構成として、上記したばね力のストレスに対向する強度を備え、耐久性に優れた弾性材料を用いることが望ましい。
【００６６】
既述した実施例では口紅Ｋを収納する口紅容器の構成について説明したが、上記説明した構成の容器には口紅以外の棒状化粧料を収納することもできる。例えば、アイシャドやリップクリーム、ファンデーション（コンシーラ等顔色の補正用のものや化粧下地を含む）等、棒状に形成可能な化粧料であれば適用可能である。これらの棒状化粧料を収納した場合にも、ワンタッチで化粧料を出没させ、任意の位置まで繰り出した化粧料を、目的の箇所に押圧して塗布することができる。
【００６７】
以上本発明の実施例について説明したが、本発明はこうした実施例に何等限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々なる様態で実施し得ることは勿論である。

BACKGROUND OF THE INVENTION
The present invention relates to a bar-shaped cosmetic container for feeding and storing a bar-shaped cosmetic such as lipstick.
[0002]
[Prior art]
Conventionally, as this type of stick-shaped cosmetic container, for example, those described in Japanese Utility Model Laid-Open Nos. 56-60507, 58-86018, and 58-88913 are known. These bar-shaped cosmetic containers have an operation unit on the side surface of the main body, and when the operation unit is slid in the longitudinal direction of the main body, the bar-shaped cosmetic stored inside the main body follows the movement of the operation unit. Moves up and down inside the main body. Further, in these bar-shaped cosmetic containers, the above-described operation unit is connected to a lid provided in the opening at the top of the main body, and the opening is closed by the sliding operation of the operation unit. Is designed to open and close. Therefore, by holding the stick-shaped cosmetic container with one hand and sliding the operation unit, the lifting and lowering operation of the stick-shaped cosmetic in the main body and the opening / closing operation of the lid can be performed simultaneously. This realizes a stick-shaped cosmetic container excellent in feeling of use that allows the material to be fed and stored.
[0003]
[Problems to be solved by the invention]
However, in each of the bar-shaped cosmetic containers having the above-described configuration, in order to achieve the performance required for the bar-shaped cosmetic container for the purpose of paying out and applying the bar-shaped cosmetic, the sliding operation of the operation unit is performed as a bar-shaped cosmetic. There was a problem that the mechanism to convey to was complicated. That is, a stick-shaped cosmetic material such as lipstick is applied by feeding a predetermined amount from a container and pressing it against a use site such as a lip. Therefore, the bar-shaped cosmetics fed out from the container are required to maintain a stopped state even when a force is applied vertically from above at an arbitrary position where the bar-shaped cosmetics are fed out. In the mechanism for transmitting the sliding motion of the operation unit to the bar-shaped cosmetic, the bar-shaped cosmetic can be stopped at an arbitrary position against the force applied from above. It was accompanied by a complicated structure.
[0004]
Among the above-described conventionally known stick-shaped cosmetic containers, in the configuration shown in Japanese Utility Model Laid-Open No. 56-60507 and Japanese Utility Model Laid-Open No. 58-88913, the sliding motion of the operation unit with respect to the holding member holding the stick-shaped cosmetic material. In order to realize a structure in which the bar-shaped cosmetic is stopped at an arbitrary position against the force applied from above, the operation unit and the holding member are attached to both ends of the belt-shaped elastic member. The belt-shaped elastic member is connected to the belt-shaped elastic member by bending the middle of the belt-shaped elastic member at the bottom of the bar-shaped cosmetic container and changing the direction by 180 degrees. It is configured to be arranged inside. With such a configuration, the holding member that holds the bar-shaped cosmetic is stopped at an arbitrary position in the main body against the force applied from above by the resistance (frictional force) generated in the curved portion. It becomes possible. However, in such a configuration, a member having sufficient strength and flexibility is selected as a belt-shaped member, and a belt sliding groove having a shape that generates a predetermined frictional force with the belt-shaped member is formed. It was necessary to design and provide in a main-body part, and the structure in a stick-shaped cosmetic container was complicated.
[0005]
In the configuration shown in Japanese Utility Model Laid-Open No. 58-86018, the operation unit to which a sliding force is applied along the main body unit and the holding unit for holding the bar-shaped cosmetic are directly connected to each other. Since the slider slides substantially integrally with the holding portion, the structure is not complicated as described above. However, in such a configuration, since the holding member does not have a structure to stop the force against the force applied from above at an arbitrary position, the stick-shaped cosmetic is pushed back into the container when the stick-shaped cosmetic is applied. Therefore, it is necessary to apply a force for holding the operation unit at a predetermined position, which is inconvenient as a cosmetic. In order to allow the holding member to stop at any position against the force applied from above, a structure that constantly presses the inner wall of the main body portion is provided on the outer peripheral portion of the internal structure including the bar-shaped cosmetic, thereby Although a configuration in which a predetermined frictional force is generated between the sliding internal structure and the inner wall of the main body portion is conceivable, such a configuration also affects the influence of this frictional force when performing an operation of feeding the bar-shaped cosmetic. This causes a problem that the operation is reduced.
[0006]
As described above, in addition to the one-touch type cosmetic container that slides the operation unit, the stick-shaped cosmetic container includes a holding member and a cam for holding the stick-shaped cosmetic with respect to a storage cylinder that stores the stick-shaped cosmetic. A container of a type that rotates a rotating cylinder engaged by a mechanism and feeds a stick-shaped cosmetic is well known. In such a bar-shaped cosmetic container, it is possible to hold the fed-out bar-shaped cosmetic at an arbitrary position due to the shape of the spiral groove constituting the cam mechanism. However, in this type of bar-shaped cosmetic container, since the operation of rotating the rotating cylinder with respect to the storage cylinder is required, the bar-shaped cosmetic cannot be delivered with one touch, and the operability is insufficient. Since the bar-shaped cosmetic is fed out while rotating with respect to the main body, the fed-out bar cosmetic may be in an undesired direction. Furthermore, in order to improve the operability, when trying to link the feeding operation of the bar-shaped cosmetic and the opening / closing operation of the lid body, it is necessary to incorporate a mechanism for opening / closing the lid body into the cam mechanism having the spiral groove described above. There arises a problem that the structure becomes complicated.
[0007]
The present invention solves such problems, and in a one-touch type bar-shaped cosmetic container, without complicating the structure, the bar-shaped cosmetic fed out from the container is opposed to the force applied from above at an arbitrary position. It was made for the purpose of making it possible to stop, and the following configuration was adopted.
[0008]
[Means for solving the problems and their functions and effects]
The bar-shaped cosmetic container of the present invention is a bar-shaped cosmetic container that stores the bar-shaped cosmetic so as to be movable up and down,
A holding member for holding the bar-shaped cosmetic;
The holding member for holding the stick-shaped cosmetic is stored, and a cylindrical storage hole having one end opened as an opening and the other end closed is formed inside, and part of a wall surface forming the storage hole A main body having a long hole in a linear shape;
On the outer surface of the main body part, an operation part slidably attached along the elongated hole;
A connecting member that connects the operating portion and the holding member through the elongated hole, and moves the holding member within the main body according to the sliding movement of the operating portion;
When an external force is not applied to the operation portion, a predetermined resistance is generated to prevent the holding member from moving within the main body, and when an external force is applied to the operation portion, the resistance is relaxed or released. A resistance generating member that enables movement of the holding member within the housing hole in the main body portion;
It is a summary to provide.
[0009]
The bar-shaped cosmetic container of the present invention configured as described above is an operation that is slidably attached along a long hole formed in a linear shape on a part of the wall surface forming the storage hole in the main body. When the external force is not applied to the part, a predetermined resistance is generated, and the movement of the holding member in the main body is prevented. When an external force is applied to the operation portion, the resistance is relaxed or released, and the holding member that holds the bar-shaped cosmetic material can move within the housing hole in the main body portion, and the bar-shaped cosmetic material moves up and down.
[0010]
According to such a bar-shaped cosmetic container, when no external force is applied to the operation portion, the predetermined member prevents the movement of the holding member within the main end portion. It can be locked at any position. Therefore, even if the bar-shaped cosmetic material fed to an arbitrary position is pressed and applied to a target place such as a lip, the bar-shaped cosmetic material is not pushed back into the bar-shaped cosmetic material container. Further, the resistance to lock the holding member in this way is relaxed or released when an external force is applied to the operation unit, that is, when the operation unit is slid to raise or lower the bar-shaped cosmetic, so that the operation unit is slid. Sometimes, the bar-shaped cosmetic can be smoothly moved up and down without being affected by the resistance of locking the holding member.

Moreover, the lipstick container 10 includes, as a mechanism realized by the structure of these members, a holding mechanism for holding the lipstick K fed out from the lipstick container 10 at an arbitrary position, and an elevating mechanism related to the feeding operation of the lipstick K. And a lid closing mechanism for automatically closing the lid 30 when the lipstick K is stored in the lipstick container 10. In the lipstick container 10 of the present embodiment, the lipstick K can be fed and stored by sliding the operation portion 64 with respect to the main body portion 20.
[0028]
The main body 20 has a storage hole 20a formed in the longitudinal direction thereof, and is configured by joining a pair of frames 21a and 21b that form the storage hole 20a substantially symmetrically by an ultrasonic welding method. 3 shows the frame body 21b, and FIG. 4 shows the frame body 21a. In addition, the main-body part 20 is good also as joining by other methods, such as joining with an adhesive agent, besides joining by an ultrasonic welding method. The storage hole 20 a included in the main body 20 has a closed shape at one end and forms the bottom surface of the main body 20. Further, the other end of the storage hole 20 a is opened at the opening 22. Hereinafter, in the lipstick container 10 of the present embodiment, the opening 22 side is referred to as the upward direction, and the opposite side is referred to as the downward direction.
[0029]
The main body 20 is formed in a shape in which the periphery of the opening 22 is inclined. In the vicinity of the opening 22 and at the joint between the frames 21a and 21b, a shaft 31b for opening and closing the lid 30 described later is provided on the lower side of the inclined surface. Further, an engaging plate 82 is disposed on the side portion of the main body portion 20 from the vicinity of the shaft 31b to the vicinity of the bottom surface of the main body portion 20, that is, along the longitudinal direction of the main body portion 20 (see FIG. 3). ). The engagement plate 82 has an uneven surface 84 on the inner side (side facing the storage hole 20a). FIG. 5 is an explanatory view showing the appearance of the engagement plate 82. 5A shows a state where the engagement plate 82 is viewed from the concave and convex surface 84 side, and FIG. 5B illustrates a state where the engagement plate 82 is viewed from the arrow B side in FIG. 5A. As shown in FIG. 5, the engagement plate 82 forms a fine line-shaped convex structure in the concavo-convex surface 84 in a direction perpendicular to the longitudinal direction of the main body 20 from the upper end to the lower end. Here, the engagement plate 82 is bonded to the frame body 21b with an adhesive. The engaging plate 82 is related to the holding mechanism described above, and the holding mechanism will be described in detail later. Further, in the frame body 21a constituting the main body 20, a first protrusion 74 is formed on the inner wall of the storage hole 20a (see FIG. 4). The first protrusion 74 serves to guide the sleeve 40 that slides in the storage hole 20a or to restrict the movement of the sleeve 40, and relates to the lifting mechanism described above, and will be described in detail later.
[0030]
The lid 30 is a member that opens and closes the opening 22. The lid 30 has a protrusion 31a having a through hole at a predetermined position on the periphery, and the hinge 31 is formed by fitting the shaft 31b described above into the through hole of the protrusion 31a. The lid 30 is supported by the hinge 31 so that the opening 22 can be opened and closed. As will be described later, the lid 30 is pushed open by the tip of the sleeve 40 when the lipstick K is extended. Further, since the hinge 31 is formed so as to generate a predetermined resistance when the lid 30 is opened and closed, the lid 30 can be freely angled by applying a force to the lid 30 with the finger in the opening direction. It can also be opened and locked.
[0031]
An annular convex portion 32 is formed inside the lid body 30, and the annular convex portion 32 fits inside the opening portion 22 when the lid body 30 is closed. The protrusion 31a includes a third protrusion 34 at an end thereof. The third protrusion 34 is related to the lid closing mechanism described above together with a later-described fourth protrusion 42 included in the sleeve 40, and will be described in detail later.
[0032]
The sleeve 40 is accommodated in the accommodation hole 20a so as to be slidable in the vertical direction, and a holding portion 50 for holding the lipstick K is accommodated therein so as to be slidable in the vertical direction. The sleeve 40 has a length that can accommodate the entire length of the lipstick K held by the holding portion 50. Further, the upper end surfaces of the sleeve 40 and the lipstick K are inclined, and this inclined surface is formed substantially parallel to the inclined surface in the opening 22. The cross sections of the sleeve 40, the holding part 50, and the lipstick K are all substantially circular. Here, a fourth protrusion 42 related to the lid closing mechanism is provided at a predetermined position near the upper end surface inclined in the sleeve 40 (see FIGS. 2 and 3). The holding | maintenance part 50 is supporting the lipstick K from the downward direction, and the lower end part of the lipstick K is fitted.
[0033]
FIG. 6 shows an appearance of the sleeve 40 as viewed from three different directions, FIG. 7 is an exploded perspective view showing a state in which the holding portion 50 and the operation member 62 are removed from the sleeve 40, and FIG. FIG. 62 is an explanatory diagram showing the appearance of side surfaces from two different directions in 62. FIG. 8B shows a state where the operation member 62 is viewed from the direction of arrow B in FIG. The sleeve 40 is formed with a cam groove 72 and a guide groove 78, and the holding portion 50 is provided with an engagement hole 52 with which the operation member 62 is engaged. The operation member 62 includes an operation portion 64 for receiving a force applied from the outside in order to feed out the lipstick K, and a second protrusion 66 that penetrates and engages with the engagement hole 52 described above. Here, the operating member 62 is formed by bending a region connecting the operating portion 64 and the second protrusion 66 into a U-shape, and achieves a predetermined elasticity in the U-shaped structure, and a spring. A portion 68 is formed. Further, the operation member 62 has a concave portion 65 that is sandwiched between the engagement plate 82 provided in the main body portion 20 and is engaged with the operation member 64 on the back side of the operation portion 64. In the operation member 62, three engagement protrusions 67 are formed on the surface of the operation member 62 that is in contact with the concavo-convex surface 84 of the engagement plate 82 among the surfaces that form the recess 65. The structures of the cam groove 72, the guide groove 78, the engagement hole 52, the second protrusion 66, and the like described above are related to the operation of extending the lipstick K, and will be described in detail later. Further, the spring portion 68 and the engagement protrusion 67 relate to an operation of locking the lipstick K fed out from the lipstick container 10 at an arbitrary position, and a detailed description thereof will be described later.
[0034]
Next, a holding mechanism that is a mechanism for holding the lipstick K fed out in the lipstick container 10 at an arbitrary position will be described. This holding mechanism is realized by the engagement plate 82, the operation member 62, and the holding unit 50 described above. First, the operation of the holding mechanism when the holding unit 50 that holds the lipstick K is locked at an arbitrary position will be described, and then the holding unit 50 that holds the lipstick K in order to feed or store the lipstick K is locked. The operation of the holding mechanism when releasing the state will be described.
[0035]
FIG. 9 is an explanatory view schematically showing the engagement relationship between the operation member 62 and the engagement plate 82 constituting the holding mechanism. 9A shows a state when the holding unit 50 is locked at an arbitrary position, and FIG. 9B shows a state when the holding state of the holding unit 50 is released. As described above, the operation member 62 is engaged with the inside of the holding portion 50 by passing the second protrusion 66 through the engaging hole 52 of the holding portion 50, and constitutes a U-shaped spring portion 68. In a state where the portion to be stored is housed in the lower region of the holding unit 50, it is disposed in the lipstick container 10 (see FIGS. 2 and 7). At this time, in the spring portion 68, the operation member 62 is placed in the lipstick container 10 so as to generate a force in a direction (in the direction of the arrow in FIG. 9A) to move the operation portion 64 and the second protrusion 66 away from each other. It is arranged in the inside.
[0036]
When such a force is generated in the spring portion 68 of the operation member 62, the surface that forms the recess 65 of the operation member 62 and that has the three engagement protrusions 67 is the engagement plate attached to the main body portion 20. It is pressed toward the uneven surface 84 of 82. Accordingly, the three engaging protrusions 67 engage with the concavo-convex structure formed on the concavo-convex surface 84. Therefore, even when an external force in the vertical direction is applied to the lipstick K, the operation member 62 is positioned at a predetermined position with respect to the engagement plate 82 due to the engagement relationship between the three engagement protrusions 67 and the uneven structure on the uneven surface 84. Since it is locked, the lipstick K is not moved by the external force.
[0037]
When the lipstick K is extended or stored, the user slides the operation unit 64 along the outer wall of the main body 20 while holding the lipstick container K. When such an operation is performed, in the operation unit 64, a force that works in the vertical direction along the outer wall of the main body unit 20 and a force that presses the operation unit 64 perpendicularly to the main body unit 20 work (FIG. 9B). ) Arrow direction). Such a force that presses the operation portion 64 perpendicularly to the main body portion 20 is a force that is opposite to the force that causes the operation portion 64 and the second protrusion 66 generated by the spring portion 68 to move away from each other. Thereby, the engagement state between the uneven surface 84 of the engagement plate and the three engagement protrusions 67 described above is released. Therefore, the state in which the holding portion 50 holding the lipstick K is locked at a predetermined position is released, and the holding portion 50 moves up and down according to the slide operation of the operation portion 64 connected through the engagement hole 52, As a result, the lipstick K moves up and down.
[0038]
The force that holds the holding part 50 realized by the holding mechanism is opposed to the force that works in the direction of pushing the holding part 50 downward when the lipstick K fed from the main body part 20 is pressed against the lips and applied. And what is necessary is just enough to maintain the state which hold | maintained the holding | maintenance part 50 in the position where the lipstick K was let out the predetermined amount. Such a force for locking the holding portion 50 can be realized, and the engagement surface can be easily released by the force applied to the operation portion 64 to raise and lower the lipstick K. What is necessary is just to set the shape of the uneven structure on 84, the magnitude | size of the engagement protrusion 67, or the structure of the spring part 68. FIG.
[0039]
Next, an elevating mechanism for realizing the delivery of the lipstick K in the lipstick container 10 will be described. The elevating mechanism includes an operation member 62 including an operation portion 64 and a second protrusion 66, a sleeve 40 including a cam groove 72 and a guide groove 78, a frame body 21b including a first protrusion 74, and an engagement hole 52. This is realized by the holding unit 50 or the like provided. The elevating mechanism moves the sleeve 40 and the holding unit 50 holding the lipstick K up and down in the storage hole 20a by transmitting the operating force applied to the operating unit 64 to the sleeve 40 and the holding unit 50. Hereinafter, the structure of each member constituting the elevating mechanism and the operation during the feeding operation of the lipstick K will be described.
[0040]
The operation unit 64 is a member to be operated with a finger to cause the lipstick K to appear and disappear. The operation portion 64 is slidably disposed along an operation groove 20 d (see FIGS. 3 and 4) formed in the longitudinal direction on the side portion of the main body portion 20. The operation groove 20d is provided on the side surface on the hinge 31 side at the joint between the frame bodies 21a and 21b.
[0041]
Further, as described above, the operation member 62 including the operation unit 64 is connected to the holding unit 50 at the second protrusion 66 provided at the end, and therefore, the operation member 62 and the holding unit 50 are different from each other. The lipstick K can be moved up and down by moving together and sliding the operation unit 64. When the lipstick K is completely stored in the lipstick container 10, the operation portion 64 is located at the lower end portion of the operation groove 20 d (the position shown in FIGS. 1B and 1C). The lipstick K is fed out as it slides toward the upper end of the operation groove 20d (the position shown in FIG. 1D). As described above, the operation member 62 connected to the holding portion 50 by the second protrusion 66 has a structure from the spring portion 68 to the second protrusion 66 in the state where the operation member 62 is integrated with the holding portion 50 in the lipstick container 10. And stored in the sleeve 40.
[0042]
As described above, the sleeve 40 has the cam groove 72 and the guide. Groove 7 8 are formed. The guide groove 78 has a hole structure formed in the longitudinal direction of the sleeve 40, and forms a horizontal portion 78a that bends at a substantially right angle at the lower end thereof (see FIG. 6). As described above, when a part of the holding portion 50 and the operation member 62 (a structure from the second protrusion 66 to the spring portion 68) is housed in the sleeve 40, the remaining area of the operation member 62 is guided by this guide. It protrudes out of the sleeve 40 through the groove 78. Hereinafter, a region where the operation member 62 is engaged with the guide groove 78 and connecting the operation portion 64 and the spring portion 68 is referred to as an engagement shaft 69 (see FIG. 8).
[0043]
Here, when the engagement shaft 69 is engaged with the horizontal portion 78 a of the guide groove 78, the movement of the operation portion 64 is transmitted to the sleeve 40 in addition to the holding portion 50. Therefore, in such a case, when the operation unit 64 is slid from the lower end side toward the upper end side, the sleeve 40 and the holding unit 50 are integrally raised in accordance with this movement. Therefore, the lipstick K in the sleeve 40 moves with the sleeve 40 and does not move relative to the sleeve 40. Further, when the engagement shaft 69 of the operation member 62 is released from the horizontal portion 78a in a state where the sleeve 40 is locked at a predetermined position, the holding portion 50 is slid and raised within the locked sleeve 40. It becomes like this. Accordingly, the lipstick K in the sleeve 40 rises relative to the sleeve 40.
[0044]
In the sleeve 40, a notch 78c is provided at the lower end of the guide groove 78 (see FIG. 6A). The notch 78 c enables the operation of accommodating the holding portion 50 connected to the operation member 62 in the engagement hole 52 in the sleeve 40 when the lipstick container 10 is assembled. That is, when the holding portion 50 integrated with the operation member 62 is pushed into the sleeve 40, the engagement shaft 69 of the operation member 62 is guided to the notch portion 78 c and fits into the guide groove 78.
[0045]
The cam groove 72 provided with the guide groove 78 in the sleeve 40 is bent in one direction (a direction away from the adjacent guide groove 78) at the lower end portion of the linear portion 72b and the linear portion 72b formed in the longitudinal direction of the sleeve 40. Cam portion 72a (see FIGS. 3 and 7). The cam groove 72 engages with the first protrusion 74 (see FIG. 4) described above included in the frame body 21a. When the movement of the operation portion 64 is transmitted to the sleeve 40 by the engagement between the operation member 62 and the horizontal portion 78 a of the guide groove 78, the sleeve 40 engages with the first protrusion 74 in the cam groove 72. The inside of the storage hole 20a is moved up and down while moving the position. When the sleeve 40 is raised and the engagement position of the first protrusion 74 is shifted from the straight portion 72b to the cam portion 72a, the sleeve 40 slightly rotates in the bending direction according to the shape of the cam portion 72a. When the first protrusion 74 reaches the end of the cam portion 72a and is locked at that end, the rise of the sleeve 40 also stops. The cam portion 72 a rotates the sleeve 40 as described above to release the engagement shaft 69 of the operation member 62 from the horizontal portion 78 a of the guide groove 78, and the engagement shaft 69 is moved to the longitudinal direction of the guide groove 78. This is a structure for allowing movement along the direction and locking the sleeve 40 at a predetermined position.
[0046]
Below, operation | movement of the raising / lowering mechanism at the time of operating the operation part 64 and paying out the lipstick K is demonstrated. FIG. 10 is an explanatory diagram for explaining the operation of the lifting mechanism when the lipstick K is fed out. FIG. 10 shows the state of engagement between the first protrusion 74 and the cam groove 72 and the state of engagement between the engagement shaft 69 and the guide groove 78, and the state in which the sleeve 40 and the cosmetic K are fed out in each state. And the position of the operation unit 64. In FIG. 10, the state in which the sleeve 40 rotates is replaced with a planar movement.
[0047]
Now, it is assumed that the lid 30 is closed and the lipstick K is completely stored in the main body 120 (state shown in FIG. 1B). In this state, the operation portion 64 is located at the lower end of the operation groove 20d, and the first protrusion 74 formed on the inner wall of the main body portion engages with the upper end portion of the cam groove 72 of the sleeve 40, and further, the operation member The engaging shaft 69 of 62 is engaged with a horizontal portion 78a provided at the lower end portion of the guide groove 78 formed in the sleeve 140 (state shown in FIG. 10A).
[0048]
From this state, when the operation unit 64 is operated with a finger and slid upward, the entire operation member 62 rises integrally with the holding unit 50. Since the engagement shaft 69 of the operation member 62 is engaged with the horizontal portion 78 a of the guide groove 78 formed in the sleeve 40, the sleeve 40 is integrated with the operation member 62 and the holding portion 50. To rise. When the operation portion 64 is slid by a predetermined amount, the tip of the raised sleeve 40 comes into contact with the annular convex portion 32 of the lid 30. When the operation portion 64 is further slid upward, the distal end portion of the sleeve 40 pushes open the lid body 30 and rises beyond the annular convex portion 32 and is fed out of the main body portion 20 from the opening portion 22.
[0049]
When the operating portion 64 is slid upward in this way, the first protrusion 74 is guided below the straight portion 72 b along the straight portion 72 b of the cam groove 72 and eventually formed at the lower end portion of the cam groove 72. Reaches the cam portion 72a. Since the cam portion 72a is bent in the predetermined direction described above, the sleeve 40 slightly rotates when the first protrusion 74 is guided in the cam portion 72a. By the slight rotation of the sleeve 40, the engagement shaft 69 of the operation member 62 is released from the horizontal portion 78a of the guide groove 78 (state shown in FIG. 10B).
[0050]
Thereafter, when the operation portion 64 is further slid upward, the first protrusion 74 formed on the inner wall surface of the main body portion 20 is engaged with the lower end portion of the cam groove 72 formed in the sleeve 40. The sleeve 40 remains locked. Here, since the engaging shaft 69 of the operation member 62 is released from the horizontal portion 78a, only the holding portion 50 connected to the operation member 62 continues to rise by the movement of the operation portion 64 sliding. As a result, the lipstick K integral with the holding portion 50 rises (in FIG. 10, the lipstick K and the holding portion 50 are collectively indicated as K), and the upper end portion of the lipstick K is the tip of the opening 22 and the sleeve 40. (See the state of FIG. 10C, see FIG. 1D). In this state, the lipstick K can be used.
[0051]
On the contrary, if the operation part 64 is slid downward in the state where the lipstick K is drawn out from the opening part 22 and the tip part of the sleeve 40, the process reverse to the above description is performed. That is, the lipstick K and the holding portion 50 are lowered and stored in the sleeve 40, and then the sleeve 40 is also completely stored in the main body portion 20. Here, when the sleeve 40 is housed in the main body 20, the operation of closing the lid 30 is performed by the lid closing mechanism described above.
[0052]
Hereinafter, a lid closing mechanism executed when the lipstick K is stored in the lipstick container 10 will be described. The lid closing mechanism is realized by the lid 30 and the sleeve 40 or the like. As described above, the lid 30 is provided with the third protrusion 34, and the sleeve 40 is provided with the fourth protrusion 42. When the operation portion 64 is slid downward along the operation groove 20d to store the lipstick K, the sleeve 40 is provided when the sleeve 40 storing the lipstick K is stored in the main body portion 20. The fourth protrusion 42 engages with the third protrusion 34 of the lid 30, and a downward force acts on the third protrusion 34. When such a force is applied to the third protrusion 34, a portion of the lid 30 that fits the shaft 31 b provided in the main body 20 serves as a fulcrum, and the third protrusion 34 serves as a force point. Rotates in a direction to close the opening 22. After the sleeve 40 for storing the lipstick K is completely stored in the main body 20, when the lid 30 is brought into contact with the upper end of the main body 20 and the lid 30 is closed, the lipstick container 10 is in the initial state ( 1 (A) to (C).
[0053]
According to the lipstick container 10 of the present embodiment configured as described above, the lipstick K can be prepared in a state where it can be used with one touch by operating the operation unit 64 with one hand, and the lipstick that has been fed to a desired position. Even if the operation of applying K directly on the lips is performed, the lipstick K is not pushed back into the lipstick container 10. That is, when the operating force is not applied to the operating portion 64, the operating member 62 engages with the engagement plate 82. Therefore, the holding portion 50 that holds the lipstick K against the force applied in the vertical direction is provided. It can be held at any position. Therefore, it is possible to improve usability regarding the operation of applying lipstick.
[0054]
The engagement relationship between the operation member 62 and the engagement plate 82 related to the holding of the lipstick K is a force acting in a direction perpendicular to the direction in which the lipstick K moves up and down, and the operation portion 64 is connected to the outer wall of the lipstick container 10. It is released by the force of pressing toward When the lipstick K is moved up and down, such a force works because the finger is pressed against the operation unit 64 to slide the operation unit 64. Therefore, when the operation unit 64 is slid to raise and lower the lipstick K, the lipstick K can be raised and lowered smoothly without being affected by the engagement relationship between the operation member 62 and the engagement plate 82.
[0055]
Further, the holding mechanism for holding the lipstick K at an arbitrary position is realized by an engagement relationship between the operation member 62 including the operation unit 64 and the engagement plate 82 attached to the main body unit 20. Therefore, providing the holding mechanism does not complicate the structure of the lipstick container 10 as a whole. In particular, in the present embodiment, the operation member 62 having the operation unit 64 is fixed to the holding unit 50 and the both are integrally moved up and down. With such a simple configuration, the movement of the operation unit 64 causes the holding unit 50 to move. Can be communicated to.
[0056]
In the lipstick container 10 of the present embodiment, a force for engaging the operation member 62 with the engagement plate 82 in the holding mechanism (a force for pressing the three engagement protrusions 67 of the operation member 62 against the uneven surface 84 of the engagement plate 82). Is realized by the elasticity shown by the spring portion 68 of the operation member 62. Therefore, the operation member 62 may be formed of a member such as a resin that enables the spring portion 68 to exhibit sufficient elasticity when the U-shaped spring portion 68 described above is formed. The main body 20, the lid 30, the sleeve 40, and the holding part 50 may be formed of a member having sufficient strength for realizing the above-described operation, such as metal or resin.
[0057]
Here, in the lipstick container 10 of the present embodiment, the operation member 64 is provided at one end of the operation member 62, the second protrusion 66 that engages the holding portion 50 is provided at the other end, and the operation portion 64 and the lipstick K are attached. Although the holding unit 50 to be held is moved up and down integrally, another member such as a belt may be interposed between the operation unit 64 and the holding unit 50. That is, the mechanism that transmits the movement of the operation unit 64 to the holding unit 50 and raises and lowers the holding unit 50 according to the movement of the operation unit 64 may be different. Even in such a case, by providing a holding mechanism similar to that in the above embodiment, it is possible to prevent the lipstick from being pushed back into the lipstick container when the lipstick fed out from the lipstick container is applied.
[0058]
In this embodiment, a part of the operation member 62 formed integrally with the operation unit 64 is formed in a U shape to form the spring unit 68, thereby realizing the pressing force described above. The pressing force may be obtained by another configuration. As another example of the configuration, FIG. 11 shows a configuration of an operation member 162 that can be used in place of the operation member 62 of the above embodiment. In the operation member 162 in FIG. 11, the same reference numerals are given to configurations common to the operation member 62 of the above embodiment, and the description thereof is omitted. The operation member 162 shown in FIG. 11 is divided into two members, a first member 161 having an operation portion 64 and a second member 163 having a second protrusion 66, and the first member 161 and the second member 163 are separated from each other. A spring portion 168 made of a coil spring is disposed between them. When such an operation member 162 is incorporated in a predetermined position of the lipstick container 10 instead of the operation member 62, the engagement hole 52 of the holding portion 50 that engages with the second protrusion 66 and the recess 65 are engaged. Depending on the positional relationship with the engagement plate 82, a predetermined elastic force is generated in the spring portion 168, and the three engagement protrusions 67 of the first member 161 are pressed toward the uneven surface 84 of the engagement plate 82.
[0059]
Further, in this embodiment, in order to realize the lifting mechanism, the first protrusion 74 is provided on the inner wall surface side of the main body 20 and the cam groove 72 is provided on the sleeve 40 side. However, it is also possible to form the concavities and convexities in the opposite relationship in these engagement relationships. That is, a protrusion may be provided on the inner wall surface side of the main body 20 and a cam groove that engages with the protrusion may be provided on the sleeve 40 side. The lipstick container having such a configuration will be described below as the lipstick container 110. In the lipstick container 110, the same number is attached | subjected to the member which is common in the lipstick container 10, and detailed description is abbreviate | omitted. The lipstick container 110 has the same frame body 21b, holding part 50, and operation member 62 as the lipstick container 10 described above. Further, a frame body 121 a having a cam groove 172 instead of the first protrusion 74 and a sleeve 140 having a first protrusion 174 instead of the cam groove 72 are provided. FIG. 12 shows the configuration of the frame 121a, and FIG. 13 shows an exploded perspective view showing a state in which the holding unit 50 and the operation member 62 are removed from the sleeve 140.
[0060]
The cam groove 172 formed on the inner wall of the frame body 121a engages with the first protrusion 174 formed on the sleeve 140. When the movement of the operation portion 64 is transmitted to the sleeve 140 via the engagement shaft 69, the sleeve 140 moves up and down in the storage hole 20 a while sliding the first protrusion 174 along the cam groove 172. The cam groove 172 includes a straight portion 172b formed in the longitudinal direction of the storage hole 20a, and a cam portion 172a bent in one direction (on the hinge 131 side) at the upper end of the straight portion 172b (see FIG. 12). When the sleeve 140 is raised and the engagement position of the first protrusion 174 is shifted from the straight portion 172b to the cam portion 172a, the sleeve 140 is slightly rotated in the bending direction according to the shape of the cam portion 172a. When the first protrusion 174 reaches the end of the cam portion 172a and is locked at the end, the rise of the sleeve 140 also stops. The cam portion 172 a rotates the sleeve 140 to release the engagement shaft 69 from the horizontal portion 78 a as in the above-described embodiment, and enables the engagement shaft 69 to slide along the guide groove 78. At the same time, the sleeve 140 is locked at a predetermined position.
[0061]
In the lipstick container 110 described above, the lipstick feeding operation can be realized in the same manner as the lipstick container 10 of the embodiment described above, and is realized by the engagement relationship between the operation member 62 and the engagement plate 82. By providing the holding mechanism, it is possible to prevent the lipstick from being pushed back into the lipstick container 110 when performing the operation of applying the fed lipstick.
[0062]
In the above-described embodiment, the third protrusion 34 is provided on the lid 30 and the fourth protrusion 42 is provided on the sleeve 40, and both are engaged when the sleeve 40 is stored in the main body 20. As a result, the lid 30 is closed at the same time when the lipstick K is stored, thereby improving the operability when performing a series of operations such as feeding out, applying, and storing the lipstick. This can be done with a single finger while holding the lipstick container with one hand. Here, the mechanism related to the opening and closing of the lid 30 may be realized by another configuration. For example, a predetermined member that moves up and down integrally with the sleeve may be provided until the sleeve moves to a predetermined position, and the predetermined member and the lid may be connected to open and close the lid. That is, the predetermined member moves up and down together with the sleeve until the lipstick is fed out beyond the sleeve, and the lid is pressed by the predetermined member to open when the sleeve is lifted. The lid is pulled down by a predetermined member to be in a closed state. By adopting such a configuration, it is possible to feed and store the lipstick from the lipstick container having the lid with one touch by the operation of sliding the operation unit, as in the above embodiment.
[0063]
In the lipstick container of the embodiment described above, the holding part has a dish-like shape, supports the lipstick K from its lower end part, and fits the lower end part of the lipstick K to this holding part to hold the lipstick K. Although it is fixed to the holding part, the holding part may have other shapes. For example, the holding part formed as a circular frame may support the lipstick K by sandwiching its side face at the bottom, and the lipstick K can be fixed and connected to a member that conveys the movement of the operation part. It ’s fine.
[0064]
In the above embodiment, a separate lid is attached to the opening of the lipstick container, and the lid is pushed open by the rising sleeve. However, the lid is abolished and the end of the operation member is moved to the shutter. You may comprise as. In such a case, since the shutter opens and closes the opening in accordance with the slide operation of the operation unit, a lid made of a separate member becomes unnecessary.
[0065]
In the above-described embodiment, the hinge provided at the connection portion between the lid and the main body may be configured to bias the spring force in the closing direction with respect to the lid. With such a configuration, it is possible to carry out the lipstick K from feeding to storing with one touch without providing the lid closing mechanism in the embodiment. In this case, it is desirable to use an elastic material having a strength that opposes the stress of the spring force described above and excellent in durability as a configuration of the belt.
[0066]
In the embodiment described above, the configuration of the lipstick container for storing the lipstick K has been described. However, a stick-shaped cosmetic other than the lipstick can be stored in the container having the above-described configuration. For example, cosmetics that can be formed into a stick shape, such as eye shadows, lip balms, and foundations (including facial colors such as concealers and makeup bases) are applicable. Even when these bar-shaped cosmetics are stored, the cosmetics can be made to appear and disappear with one touch, and the cosmetics fed to an arbitrary position can be pressed and applied to a target location.
[0067]
Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.
