Description

【０００１】
【発明の属する技術分野】
本発明は、棒状化粧料を容器から出没可能とする棒状化粧料繰出容器に関する。
【０００２】
【従来の技術】
従来、棒状化粧料を把持する芯チャックが、これを収容する筒容器内で、螺合機構及び回転止め機構に従って進退可能とされて、棒状化粧料が筒容器の先端から出没可能とされる棒状化粧料繰出容器が市場に供されている。
【０００３】
この種の棒状化粧料繰出容器としては、円筒形状の筒容器と、棒状化粧料を把持し筒容器内に進退可能に内挿される芯チャックと、内周面に螺旋溝が形成され筒容器の後部側に内挿されて当該筒容器に相対回転自在に装着されると共に芯チャックの後部側が内挿される螺子筒と、を具備し、この螺子筒の螺旋溝に、芯チャックの後部側に突設されている螺合突起が係合することで螺合機構が構成されると共に、筒容器内の芯チャックの進退範囲に軸線方向に沿って形成される進退溝に、当該芯チャックの棒状化粧料を把持する部分が係合することで、芯チャックの進退案内機構及び回転止め機構が構成され、筒容器と螺子筒とが相対回転されると、上記螺合機構、進退案内機構及び回転止め機構に従って芯チャックが進退し、当該芯チャックに把持されている棒状化粧料が筒容器の先端から出没する棒状化粧料繰出容器が知られている（例えば、特許文献１参照）。

【０００５】
【発明が解決しようとする課題】
しかしながら、上記棒状化粧料繰出容器にあっては、筒容器と螺子筒との相対回転時に、回転止めとして機能している芯チャックに回転トルクが伝達されるため、これに把持されている棒状化粧料に捩れ力が作用し、当該棒状化粧料が破損する虞がある。
【０００６】
本発明は、このような課題を解決するために成されたものであり、棒状化粧料の破損が防止されると共に小型化が図れる棒状化粧料繰出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】
本発明による棒状化粧料繰出容器は、棒状化粧料を把持する芯チャックが、これを収容する筒容器内で、螺合機構及び回転止め機構に従って進退可能とされて、棒状化粧料が筒容器の先端から出没可能とされる棒状化粧料繰出容器において、芯チャックは、棒状化粧料を把持するチャック部と、このチャック部の後端から軸線方向に沿って延びる軸体部と、を具備し、この軸体部が、回転止め機構を構成し筒容器に回転不能に係合する係合部を備えると共に、チャック部を回転可能に連結することを特徴としている。
【０００８】
このような棒状化粧料繰出容器によれば、螺合機構及び回転止め機構に従って筒容器内の芯チャックが進退する際に生じ、回転止め機構を構成する芯チャックの軸体部に作用する回転トルクは、この軸体部と棒状化粧料を把持するチャック部とが回転可能に連結されていることから、チャック部に伝達されることは無い。
【０００９】
ここで、上記棒状化粧料繰出容器の機能を十分に発揮する好適な構成としては、具体的には、筒容器には、筒内の後部側に、内周面に螺合突起を備える螺子筒が相対回転自在に装着され、芯チャックの軸体部は螺子筒に内挿され、その外周面に螺子筒の螺合突起に係合する螺旋溝を備えると共に係合部としての凹設溝を軸線方向に沿って備え、筒容器は、その内周面のチャック部の後退限位置と螺子筒の先端との間に、軸体部の凹設溝に係合する係合片を具備し、螺子筒の螺合突起及び軸体部の螺旋溝が螺合機構を構成すると共に、筒容器の係合片及び軸体部の凹設溝が回転止め機構を構成するものが挙げられる。
【００１０】
また、チャック部は、棒状化粧料を把持する複数の把持片を備え、この把持片の外径が、螺子筒の外径より大とされると共に、筒容器内は、螺子筒が装着される領域の内径に対して把持片が進退する領域の内径が大とされ、軸体部の凹設溝は、軸体部の先端から軸線方向に沿って所定位置迄凹設されると共に把持片の前進時に係合片が突き当たる後端面が把持片の前進限ストッパーとされ、筒容器は、棒状化粧料が出没する先端の開口から把持片の後退限迄の範囲が、把持片の移動を可能とする孔形状とされているのが好ましい。
【００１１】
このように、把持片の前進限として機能すべく、軸体部の凹設溝が当該軸体部の先端から軸線方向に沿って所定位置迄しか凹設されていないと、当該軸体部を筒容器の先端の開口から挿入することは、軸体部の後端が筒容器内の途中に設けられている係合片に突き当たることから不可とされる。従って、軸体部を、筒容器の後端の開口から挿入していくことになるが、この時、大径の棒状化粧料に適用すべく、把持片の外径が螺子筒の外径より大とされると共に、筒容器内の螺子筒が装着される領域の内径に対して把持片が進退する領域の内径が大とされていることから、把持片を先端に備える軸体部を筒容器の後端の開口から挿入していくことは不可とされる。しかしながら、本発明では、前述したように、把持片を備えるチャック部と軸体部とが回転可能に連結されていることから、組立前は各々別体であり、加えて、筒容器の棒状化粧料が出没する先端の開口から把持片の後退限迄の範囲が、把持片の移動を可能とする孔形状とされていることから、チャック部を筒容器の先端の開口から挿入していき、軸体部を筒容器の後端の開口から挿入していき、これらを回転可能に連結する組み立てを行うことで、上記構成の棒状化粧料繰出容器が得られることになる。
【００１２】
ここで、筒容器内には、把持片の後退限位置と螺子筒の先端との間に、把持片が進退する領域の内径及び螺子筒が装着される領域の内径より小とされる中間領域が設定され、この中間領域に、凹設溝に係合する係合片が突設されていると、筒容器内の把持片が進退する領域と、この領域に連続し当該領域の内径よりその内径が小とされる中間領域との境界部に形成される内周段部が、把持片の後退限ストッパーとして機能するため、当該構成を採用するのが好ましい。
【００１３】
【発明の実施の形態】
以下、本発明による棒状化粧料繰出容器の好適な実施形態について図１〜図９を参照しながら説明する。図１は、本発明の実施形態に係る棒状化粧料繰出容器を示す外観図、図２〜図４は、棒状化粧料繰出容器の各矢視図、図５及び図６は、棒状化粧料カートリッジを示す各図、図７は、棒状化粧料カートリッジの分解斜視図であり、本実施形態の棒状化粧料繰出容器は、例えば、アイライナー、アイブロー、リップライナー等の棒状化粧料を収容し、使用者が必要に応じて適宜出没可能とする棒状化粧料繰出容器である。
【００１４】
図１に示すように、棒状化粧料繰出容器１は、全体形状が筆記具の如き細長い丸棒状（スティック状）を成し良好な外観を呈するもので、図６に示す棒状化粧料Ｍを収容する棒状化粧料カートリッジ２を、図２に示すように、カートリッジ収容容器３の先端側（図示左側）に着脱可能に備えている。
【００１５】
この棒状化粧料繰出容器１は、棒状化粧料カートリッジ２の外筒を成すカートリッジ筒６とカートリッジ収容容器３との相対回転に従って当該棒状化粧料カートリッジ２内の芯チャック７に把持されている棒状化粧料Ｍを先端から繰り出して塗布し得るもので、この棒状化粧料カートリッジ２の中程から後端迄の部分が中具２０を介してカートリッジ収容容器３内に収容され、この棒状化粧料カートリッジ２の中具２０から突出する部分及び中具２０のカートリッジ収容容器３から突出する部分が、図１及び図２に示すように、着脱可能なキャップ９により覆われると共に、カートリッジ収容容器３の後端の開口が、着脱可能な尾栓１０により閉じられている。
【００１６】
ここで、この実施形態で用いられる棒状化粧料Ｍは、図２に示すように、径の大きい（太い）棒状化粧料であり（詳しくは後述）、当該棒状化粧料繰出容器１は、この大径の棒状化粧料Ｍを収容し繰り出すのに最適な構造とされている。
【００１７】
カートリッジ収容容器３は、両端が開放されて成る円筒形状に構成されている。このカートリッジ収容容器３は、筒内の略中間位置が、中央に貫通孔を有する中仕切３ａで仕切られ、この中仕切３ａより先端側の筒内に、棒状化粧料カートリッジ２の後部を収容する空間が画成されている。
【００１８】
中仕切３ａには、周縁の４等配の位置に、先端及び後端の開口へ向けて延びる段付きの縦リブ３ｂが各々設けられている。この縦リブ３ｂは、中具２０の後端面を突き当てる下段の縦リブ３ｘと、棒状化粧料カートリッジ２の後述する螺子筒８を回転不能に連結する上段の縦リブ３ｙと、を備え、この上段の縦リブ３ｙは、下段の縦リブ３ｘより中仕切３ａ側に凹まされていると共にその凹まされている先端面が周方向に６０°で傾斜する傾斜面３ｃとされている。なお、中仕切３ａの他方側にも、棒状化粧料カートリッジ２と同様な構成のカートリッジを装着可能とすべく、上記縦リブ３ｂと同様な形状の縦リブが突設されている。
【００１９】
また、カートリッジ収容容器３は、先端の開口端に、筒内の内径より多少大きく形成され、中具２０の環状鍔部２０ａを収容する段孔３ｄを備えると共に、この段孔３ｄより軸線方向後端側の近傍位置に、中具２０を装着するための環状溝部３ｅを備えている。
【００２０】
中具２０は、例えば合成樹脂等の可撓性材で成形され、略円筒状に構成されている。
【００２１】
この中具２０は、カートリッジ収容容器３に内挿され、後端面がカートリッジ収容容器３の下段の縦リブ３ｘに当接し、全長の１／３程度先端からの外周位置に形成される環状鍔部２０ａが、カートリッジ収容容器３の段孔３ｄに突き当てられて収容されると共に、環状鍔部２０ａから後端へ所定長の外周位置に形成される環状突部２０ｂが、カートリッジ収容容器３の環状溝部３ｅに係合されることで、カートリッジ収容容器３に装着されている。
【００２２】
このカートリッジ収容容器３に装着されている中具２０は、環状突部２０ｂと後端との間に、スリットを螺旋状に切り欠いて成る切欠孔２０ｄを備えている。この中具２０は、切欠孔２０ｄを含む後部側が、当該切欠孔２０ｄにより軸線方向に伸縮可能とされて緩衝性を有し、後端側が先端側へ押圧されると、切欠孔２０ｄが先端側へ圧縮されて当該切欠孔２０ｄを含む後部側が先端側へ移動する。
【００２３】
また、中具２０には、後端寄りの内周面に、棒状化粧料カートリッジ２の外筒を成すカートリッジ筒６を相対回転自在且つ着脱可能に装着するための環状突部２０ｃが形成されている。
【００２４】
棒状化粧料カートリッジ２は、図５〜図７に示すように、段付円筒形状のカートリッジ筒６と、図６及び図７に示すように、カートリッジ筒６内に収容されて軸線方向に延在し先端に棒状化粧料Ｍを把持して進退する芯チャック７と、カートリッジ筒６内の後部側に収容されて芯チャック７と螺合する円筒形状の螺子筒８と、を備えている。これらのカートリッジ筒６、芯チャック７及び螺子筒８は、棒状化粧料Ｍを進退させる進退機構として機能する（詳しくは後述）。
【００２５】
カートリッジ筒６は、図２に示すように、上記中具２０から突出する先端側の摘み部としての大径部６ａと、図５〜図７に示すように、この大径部６ａの後端に外周段部６ｂを介し外周面が小径とされて連続する小径部６ｃと、備えている。
【００２６】
このカートリッジ筒６は、図２に示すように、その小径部６ｃが中具２０を介してカートリッジ収容容器３に内挿され、外周段部６ｂが中具２０の先端面に突き当てられ、後端寄りの外周面に形成される環状溝部６ｄが、中具２０の後端寄りの環状突部２０ｃに係合されることで、中具２０を介してカートリッジ収容容器３に相対回転自在且つ着脱可能に装着されている。
【００２７】
カートリッジ筒６は、図６及び図７に示すように、その内周面の中程に中間領域６ｊを備え、先端から中間領域６ｊの先端迄の範囲が、棒状化粧料Ｍ及びこれを把持する把持片７ｄを収容すると共にこれらが進退する進退孔６ｉとされ、中間領域６ｊの後端から筒後端迄が、螺子筒８を収容する螺子筒収容孔６ｋとされている。
【００２８】
進退孔６ｉは、図３及び図７に示すように、棒状化粧料Ｍが進退する棒状化粧料孔６ｍと、この棒状化粧料孔６ｍの外周面に連設され、芯チャック７の把持片７ｄが進退する進退溝６ｎと、を備えている。
【００２９】
棒状化粧料孔６ｍは、棒状化粧料Ｍの形状に対応する円形形状とされ、進退溝６ｎは、把持片７ｄの形状に対応する形状とされ、この進退溝６ｎは、図７に示すように、カートリッジ筒６の先端の開口から棒状化粧料孔６ｍの全長に亘って設けられている。
【００３０】
螺子筒収容孔６ｋは、略円形形状とされ、その内径が、進退孔６ｉの外径に比して小さくされている。この螺子筒収容孔６ｋには、図６及び図７に示すように、後端寄りの位置に、螺子筒８を相対回転自在且つ軸線方向移動不能に装着するための環状溝部６ｈが形成されている。
【００３１】
中間領域６ｊは、進退孔６ｉの後端に内周段部６ｘを介し内周が小径とされて連続すると共に、螺子筒収容孔６ｋの先端に内周段部６ｙを介し内周が小径とされて連続する構成とされている。この中間領域６ｊと進退孔６ｉとの境界部の内周段部６ｘは、芯チャック７の把持片７ｄ（基部７ｃ）の後退限ストッパーとして設定されている。
【００３２】
特に、この中間領域６ｊには、芯チャック７の進退機構の一部である回転止め機構及び進退案内機構を構成する係合片６ｐが設けられている。この係合片６ｐは、図６に示すように、中間領域６ｊの後端寄りの内周位置で軸線を挟む１８０°対称位置に突設されている。
【００３３】
螺子筒８は、図７に示すように、円筒形状を成す軸部８ｘと、この軸部８ｘの後端に外周段部８ｚを介し外周面が大径とされて連続する円筒形状のギヤ部８ｙとを、例えば合成樹脂等の可撓性材で一体成形して成る。
【００３４】
この螺子筒８は、図６及び図７に示すように、その内周面の先端寄りの位置に、芯チャック７の進退機構の一部である螺合機構を構成する螺合突起８ａを、軸線を挟む１８０°対称位置に各々備えている。
【００３５】
また、螺子筒８には、図７に示すように、軸部８ｘのギア部８ｙ寄りの位置で軸線を挟む１８０°対称位置に、弾性係合部８ｅ，８ｅが各々設けられている。この弾性係合部８ｅは、螺子筒８の軸部８ｘの周壁に穿設されるコの字状割溝８ｆにより形成され、成形材である合成樹脂等の可撓性に従って板バネの役割を果たす半島部８ｇと、この半島部８ｇの外周面から突出する係合突部８ｈと、を備えている。
【００３６】
また、螺子筒８には、ギヤ部８ｙの外周面に、８等配の位置で軸線方向に沿って延びる縦リブ８ｂが設けられている。この縦リブ８ｂは、山形を成すと共に、その後端面に、図６及び図７に示すように、上端面から下端面に向けて４５°の下り勾配で傾斜する傾斜面８ｄを備えている。
【００３７】
この螺子筒８は、図６に示すように、カートリッジ筒６の螺子筒収容孔６ｋに内挿され、外周段部８ｚがカートリッジ筒６の後端面に突き当てられ、半島部８ｇの係合突部８ｈがカートリッジ筒６の後端内周面６ｒに当接し（図７参照）、軸部８ｘの弾性係合部８ｅ寄りの外周位置に形成される環状突部８ｃが、カートリッジ筒６の環状溝部６ｈに係合されることで、カートリッジ筒６に相対回転自在且つ軸線方向移動不能に装着されている。
【００３８】
この螺子筒８の係合突部８ｈは、板バネを成す半島部８ｇの弾発力により付勢されてカートリッジ筒６の後端内周面６ｒに当接していることから、カートリッジ筒６との間に回転抵抗を発生する。
【００３９】
また、この状態で、螺子筒８は、図２に示すように、その各縦リブ８ｂが、カートリッジ収容容器３の上段の縦リブ３ｙ，３ｙ同士間に位置して回転方向に係合し、カートリッジ収容容器３に回転不能且つ軸線方向に移動可能に連結されている。
【００４０】
すなわち、カートリッジ収容容器３と螺子筒８とは回転不能且つ軸線方向に移動可能に連結され、カートリッジ筒６は、これらのカートリッジ収容容器３及び螺子筒８に対して相対回転自在に連結されている。
【００４１】
芯チャック７は、図６及び図７に示すように、棒状化粧料Ｍの基端部を把持するチャック部７ａと、このチャック部７ａの後端に連続し軸線方向に延在する芯チャック軸（軸体部）７ｂと、を備え、特に本実施形態では、これらのチャック部７ａと芯チャック軸７ｂとが別部品とされて、相対回転自在に連結されている。
【００４２】
図６に示すように、カートリッジ筒６の進退孔６ｉに内挿されるチャック部７ａは、図６及び図７に示すように、棒状化粧料Ｍの基端部が突き当てられる基部７ｃと、棒状化粧料Ｍの基端部を把持する把持片７ｄと、基部７ｃの後端面に連設されて突出する係合筒部７ｅとを、例えば合成樹脂等の可撓性材で一体成形して成る。
【００４３】
基部７ｃは、円形形状の棒状化粧料Ｍに略合致する円形形状の厚板に構成されている。
【００４４】
把持片７ｄは、図３及び図７に示すように、基部７ｃの四等配の外周位置に、先端側に向かって突出するように設けられている。これら四個の把持片７ｄは、図３に示すように、その内周面に、軸方向に沿って延びる突状７ｆを備え、この突状７ｆを各々有する四個の把持片７ｄが、棒状化粧料Ｍの回転方向の移動を阻止しつつ当該棒状化粧料Ｍを把持する。
【００４５】
そして、上記カートリッジ筒６の棒状化粧料孔６ｍは、円形形状の棒状化粧料Ｍの外周面に近接するように形成され、進退溝６ｎは、把持片７ｄの外周面に近接するように形成されている。このように、棒状化粧料孔６ｍ、進退溝６ｎを、棒状化粧料Ｍ、把持片７ｄに近接して形成することで、例えば落下等により作用する外力をカートリッジ筒６全体で受け止めることが可能とされ、棒状化粧料Ｍの折損の防止が図られている。
【００４６】
また、チャック部７ａの係合筒部７ｅは、図６に示すように、その内周の後端位置に、芯チャック軸７ｂを回転自在に装着するための環状溝部７ｇを備えている。
【００４７】
芯チャック軸７ｂは、図７に示すように、先端に小径軸７ｒを備え、図６に示すように、この小径軸７ｒがチャック部７ａの係合筒部７ｅに内挿され、小径軸７ｒの外周に形成される環状突部７ｈが、係合筒部７ｅの環状溝部７ｇに係合することで、当該芯チャック軸７ｂに対してチャック部７ａが回転自在に装着されている。
【００４８】
芯チャック軸７ｂは、図７に示すように、その先端近傍から後端に亘って、螺合機構を構成する螺旋溝７ｍを備えると共に、その先端から後端近傍に亘って、回転止め機構及び進退案内機構を構成する凹設溝（係合部）７ｎを、図４及び図６に示すように、軸線を挟む１８０°対称位置に各々備えている。
【００４９】
この芯チャック軸７ｂは、図６に示すように、螺子筒８に内挿され、螺旋溝７ｍが、螺子筒８の螺合突起８ａに係合されると共に、凹設溝７ｎが、カートリッジ筒６の中間領域６ｊの係合片６ｐに係合されている。この凹設溝７ｎは、図７に示すように、係合片６ｐが突き当たる後端面７ｑが芯チャック７（把持片７ｄ）の前進限ストッパーとして設定されている。
【００５０】
このような構成を有する棒状化粧料繰出容器１を組み立てる場合には、先ず、棒状化粧料カートリッジ２をユニットとして組み立てる。
【００５１】
ここで、前述のように、芯チャック軸７ｂの凹設溝７ｎは、把持片７ｄの前進限ストッパーとして機能すべく、芯チャック軸７ｂの先端から軸線方向に沿って所定位置迄しか凹設されていない（後端面まで達していない）ことから、当該芯チャック軸７ｂをカートリッジ筒６の先端の開口から挿入することは、芯チャック軸７ｂの後端面がカートリッジ筒６内途中の中間領域６ｊに設けられている係合片６ｐに突き当たることから不可である。
【００５２】
従って、芯チャック軸７ｂをカートリッジ筒６の後端の開口から挿入していくことになるが、この時、大径の棒状化粧料Ｍに適用すべく、チャック部７ａの把持片７ｄの外径が螺子筒８の外径より大にされると共に、カートリッジ筒６の螺子筒収容孔６ｋの内径に対して進退孔６ｉ（棒状化粧料孔６ｍ＋進退溝６ｎ）の内径が大とされていることから、把持片７ｄを先端に備える芯チャック軸７ｂをカートリッジ筒６の後端の開口から挿入していくことは不可とされる。
【００５３】
しかしながら、本実施形態では、前述したように、把持片７ｄを備えるチャック部７ａと芯チャック軸７ｂとが回転可能に連結されていることから、組立前は各々別体であり、加えて、カートリッジ筒６の棒状化粧料Ｍが出没する先端の開口から把持片７ｄの後退限迄の範囲（進退孔６ｉの形成範囲）が、把持片７ｄの移動を可能とする孔形状とされている。
【００５４】
従って、チャック部７ａを、その後端側の係合筒部７ｅ側から、把持片７ｄとカートリッジ筒６の進退溝６ｎとが合うようにして、カートリッジ筒６の先端の開口へ挿入していく一方で、芯チャック軸７ｂを螺子筒８に係合（螺合）してから、芯チャック軸７ｂ及び螺子筒８を、その先端側の小径軸７ｒ側から、凹設溝７ｎとカートリッジ筒６の係合片６ｐとが合うようにして、カートリッジ筒６の後端の開口へ挿入していき、カートリッジ筒６の後端面に螺子筒８の外周段部８ｚを突き当てることで、カートリッジ筒６の環状溝部６ｈに螺子筒８の環状突部８ｃが係合し、カートリッジ筒６に、芯チャック軸７ｄを係合した螺子筒８が相対回転自在且つ軸線方向移動不能に装着され、この状態で、チャック部７ａの係合筒部７ｅを芯チャック軸７ａの小径軸７ｒに押し込むことで、係合筒部７ｅの環状溝部７ｇと小径軸７ｒの環状突部７ｈとが係合し、チャック部７ａと芯チャック軸７ｂとが相対回転自在に連結される。
【００５５】
次いで、棒状化粧料Ｍを、その基端部側からカートリッジ筒６の先端の開口へ挿入し芯チャック７のチャック部７ａに把持させることで、棒状化粧料カートリッジ２が得られる。
【００５６】
このように、チャック部７ａと芯チャック軸７ｂとが相対回転自在に連結され組立前は別体であるという構成から、太径の棒状化粧料Ｍを収容する棒状化粧料カートリッジ２が容易に得られるようになっている。
【００５７】
次いで、中具２０を、その後端側からカートリッジ収容容器３の先端の開口へ内挿し、環状鍔部２０ａをカートリッジ収容容器３の段孔３ｄに突き当てることで、環状突部２０ｂがカートリッジ収容容器３の環状溝部３ｅに係合し、中具２０がカートリッジ収容容器３に装着される。
【００５８】
次いで、棒状化粧料カートリッジ２を、その後端側から、中具２０を介してカートリッジ収容容器３の先端の開口へ内挿し、カートリッジ筒６の外周段部６ｂを中具２０の先端面に突き当てることで、カートリッジ筒６の環状溝部６ｄが中具２０の環状突部２０ｃに係合し、カートリッジ筒６が中具２０を介してカートリッジ収容容器３に相対回転自在且つ着脱可能に装着されると共に、螺子筒８の各縦リブ８ｂがカートリッジ収容容器３の上段の縦リブ３ｙに係合し、螺子筒８がカートリッジ収容容器３に回転不能に連結され、これにより、棒状化粧料繰出容器１が得られる。
【００５９】
このように、本実施形態においては、棒状化粧料カートリッジ２がユニットとして組み立てられてからカートリッジ収容容器３に装着されるため、棒状化粧料繰出容器１の組み立てが容易とされ、製造コストの低減が図られている。
【００６０】
ここで、上記棒状化粧料繰出容器１を例えば床等に落下させる等すると衝撃的外力が容器１に加わるが、棒状化粧料カートリッジ２に対しては、合成樹脂等で形成される中具２０の可撓性が作用すると共に、中具２０の切欠孔２０ｄが圧縮されて軸線方向及び回転方向に移動可能とする緩衝性が作用し、落下等による衝撃が緩和されて棒状化粧料カートリッジ２側には殆ど伝達されず、従って、外力が芯チャック７に伝わることは無く、芯チャック７のチャック部７ａに把持されている棒状化粧料Ｍが抜け落ちたり、破損することが防止されている。
【００６１】
次に、このような棒状化粧料繰出容器１により棒状化粧料Ｍを塗布する場合について説明する。この場合には、カートリッジ筒６のカートリッジ収容容器３及び中具２０から露出する大径部６ａを摘むと共にカートリッジ収容容器３を摘み、これらを相対回転する。ここでは、カートリッジ収容容器３を回転するとして説明する。
【００６２】
すると、カートリッジ収容容器３の上段の縦リブ３ｙと螺子筒８の各縦リブ８ｂが回転方向に係合しているため、螺子筒８がカートリッジ収容容器３と共に一体に回転する。この時、カートリッジ収容容器３は、これに回転不能に連結されている螺子筒８の係合突部８ｈとカートリッジ筒６との間の回転抵抗に抗して回転される。
【００６３】
この時、螺子筒８の螺合突起８ａに係合している螺旋溝７ｍを有する芯チャック７は、その凹設溝７ｎが、カートリッジ筒６の回転止め機構及び進退案内機構としての係合片６ｐに回転不能且つ軸線方向移動可能に係合しているため、カートリッジ筒６内を前進し、棒状化粧料Ｍはカートリッジ筒６の先端から繰り出される。
【００６４】
この前進時にあっては、芯チャック７の凹設溝７ｎには係合片６ｐによる回転トルクが作用するが、当該凹設溝７ｎを有する芯チャック軸７ｂに対して、棒状化粧料Ｍを把持する把持片７ｄが設けられているチャック部７ａが、回転可能に連結されているため、この回転トルクは、連結部分で遮断されチャック部７ａに伝達されることは無く、棒状化粧料Ｍの破損が防止されている。
【００６５】
そして、棒状化粧料Ｍが所望長さに繰り出されたら、カートリッジ収容容器３とカートリッジ筒６との相対回転を停止する。すると、カートリッジ収容容器３に回転不能に連結されている螺子筒８の係合突部８ｈとカートリッジ筒６との間に生じている回転抵抗に従って、カートリッジ収容容器３とカートリッジ筒６とは所定の係合状態に維持される。
【００６６】
従って、この状態で、使用者は、カートリッジ収容容器３を持って棒状化粧料Ｍを塗布すれば良い。この時、塗布面から棒状化粧料Ｍ、回転止め機構を介して、カートリッジ筒６へ外力が作用するが、当該カートリッジ筒６の回転は、上記回転抵抗により阻止される。
【００６７】
ここで、カートリッジ収容容器３とカートリッジ筒６とをさらに相対回転すると、前進する芯チャック軸７ｂの凹設溝７ｎの後端面７ｑが、カートリッジ筒６の係合片６ｐの後端面に突き当たり、これにより、芯チャック７は前進限に達しそれ以上の前進が阻止され最大限に繰り出されたことになる。
【００６８】
この状態で、さらに相対回転を継続すると、芯チャック７が前進しようとしてカートリッジ筒６が当該芯チャック７に押圧され、カートリッジ筒６が前方へ移動しようとし、このカートリッジ筒６に対して係合している中具２０の後端側を介して、中具２０の切欠孔２０ｄが先端側へ圧縮される。
【００６９】
すると、螺子筒８を含む棒状化粧料カートリッジ２が、中具２０の切欠孔２０ｄの圧縮分、先端側へ移動すると共に、カートリッジ収容容器３の上段の縦リブ３ｙの傾斜面３ｃが、螺子筒８の縦リブ８ｂの傾斜面８ｄを先端側へ押し出し、これにより、縦リブ３ｙ，８ｂ同士の係合状態が解除されて、カートリッジ収容容器３の回転が螺子筒８に対して遮断される。このように、カートリッジ収容容器３の上段の縦リブ３ｙ、螺子筒８の縦リブ８ｂに各々設けた傾斜面３ｃ，８ｄが、トルクリミッターとしての役割を果たしている。
【００７０】
また、縦リブ３ｙ，８ｂ同士の係合が解除された状態で、相対回転を停止すると、中具２０の切欠孔２０ｄの圧縮中止による弾性力が中具２０の後部側に生じ、棒状化粧料カートリッジ２が後端側へ移動され、螺子筒８の縦リブ８ｂとカートリッジ収容容器３の縦リブ３ｙとが係合状態に復帰する。
【００７１】
そして、塗布が終わったら、使用者が、カートリッジ収容容器３とカートリッジ筒６とを上記とは逆方向に相対回転することで、棒状化粧料Ｍはカートリッジ筒６内に引き込まれる。
【００７２】
この時、前進時の場合と同様に、芯チャック７の凹設溝７ｎに係合片６ｐから作用する回転トルクは、芯チャック軸７ｂとチャック部７ａとが回転可能に連結されているため、当該連結部分で遮断されてチャック部７ａに伝達されることは無く、棒状化粧料Ｍの破損が防止されている。
【００７３】
ここで、上記棒状化粧料カートリッジ２にあっては、カートリッジ収容容器３を持って当該棒状化粧料カートリッジ２を所定の力で軸線方向に引っ張ると、カートリッジ筒６の環状溝部６ｄが中具２０の環状突部２０ｃから離脱し、棒状化粧料カートリッジ２がカートリッジ収容容器３から抜脱可能とされるため、消耗等により棒状化粧料Ｍを交換する必要が生じた場合には、このように棒状化粧料カートリッジ２をカートリッジ収容容器３から抜脱し、交換用（新規）の棒状化粧料カートリッジ２を上記と同様にしてカートリッジ収容容器３に装着すれば良く、利便性、実用性の向上が図られている。また、このように棒状化粧料カートリッジ２がカートリッジ収容容器３から抜脱可能とされているため、抜脱した棒状化粧料カートリッジ２を持って塗布することや、この棒状化粧料カートリッジ２を棒状化粧料繰出容器として、カートリッジ筒６と螺子筒８後端のギヤ部８ｙとを摘んで相対回転することで棒状化粧料Ｍを進退させることも可能であり、汎用性、利便性、実用性の向上がさらに図られている。
【００７４】
以上説明したように、本実施形態においては、芯チャック７の回転止め機構の構成部が凹設溝７ｎとされて芯チャック軸７ｂに設けられると共に、この芯チャック軸７ｂと棒状化粧料Ｍを把持するチャック部７ａとが相対回転自在に連結されているため、螺合機構及び回転止め機構に従って芯チャック７が進退する際に生じ凹設溝７ｎに作用する回転トルクは、チャック部７ａに伝達されることは無く、従って、棒状化粧料Ｍの破損を防止することが可能とされている。
【００７５】
また、把持片７ｄが回転止め機構を構成していないため、当該把持片７ｄを薄肉化及び短尺化することが可能とされ、棒状化粧料繰出容器１を小型化するのが可能とされている。
【００７６】
以上、本発明をその実施形態に基づき具体的に説明したが、本発明は上記実施形態に限定されるものではなく、例えば、上記実施形態においては、横断面が円形形状の棒状化粧料Ｍに対する適用を述べているが、横断面が例えば楕円形状の棒状化粧料に対しても適用可能である。
【００７７】
また、上記実施形態においては、組立の容易性、棒状化粧料Ｍの交換等を考慮し最も好ましい形態として、棒状化粧料カートリッジ２を、カートリッジ収容容器３に対して着脱可能としているが、抜脱不能に固定するようにしても勿論良い。
【００７８】
また、棒状化粧料繰出容器の構成は、上記実施形態のものに限定されるものではなく、例えば、略円筒形状を成し後部側の周壁に軸線方向に沿う長孔を有する筒容器と、棒状化粧料を把持し筒容器内に進退可能に内挿される芯チャックと、内周面に螺旋溝が形成され筒容器の後部側に上記長孔を覆うように外挿されて当該筒容器に回転自在に装着される螺子筒と、を具備し、筒容器の長孔に、芯チャックの後部側に突設されている螺合突起が遊嵌して係合することで芯チャックの進退案内機構及び回転止め機構が構成され、この螺合突起の先端が螺子筒の螺旋溝に係合することで螺合機構が構成され、筒容器と螺子筒とが相対回転されると、上記螺合機構、進退案内機構及び回転止め機構に従って芯チャックが進退し、当該芯チャックに把持されている棒状化粧料が筒容器の先端から出没する棒状化粧料繰出容器に対しても適用可能である。
【００７９】
【発明の効果】
本発明による棒状化粧料繰出容器は、螺合機構及び回転止め機構に従って筒容器内の芯チャックが進退する際に生じ、回転止め機構を構成する芯チャックの軸体部に作用する回転トルクを、この軸体部と棒状化粧料を把持するチャック部とを回転可能に連結することで、チャック部に伝達しないように構成したものであるから、棒状化粧料の破損を防止することが可能になると共に、チャック部の薄肉化及び短尺化が可能とされ繰出容器の小型化を図ることが可能となる。

[0005]
[Problems to be solved by the invention]
However, in the above-described rod-shaped cosmetic material feeding container, when the cylindrical container and the screw cylinder are rotated relative to each other, the rotational torque is transmitted to the core chuck functioning as a rotation stopper. There is a possibility that the torsional force acts on the cosmetic and the stick-shaped cosmetic is damaged.
[0006]
The present invention has been made to solve such a problem, and an object of the present invention is to provide a stick-shaped cosmetic material feeding container that can prevent the stick-shaped cosmetic material from being damaged and can be reduced in size.
[0007]
[Means for Solving the Problems]
In the stick-shaped cosmetic material feeding container according to the present invention, the core chuck for gripping the stick-shaped cosmetic material can be advanced and retracted according to the screwing mechanism and the rotation stopping mechanism in the cylindrical container for accommodating the stick-shaped cosmetic material. In the rod-shaped cosmetic material feeding container capable of appearing and retracting from the front end, the core chuck includes a chuck portion for gripping the rod-shaped cosmetic material, and a shaft portion extending along the axial direction from the rear end of the chuck portion, The shaft portion includes an engaging portion that constitutes a rotation stopping mechanism and non-rotatably engages with the cylindrical container, and connects the chuck portion rotatably.
[0008]
According to such a rod-shaped cosmetic material feeding container, when the core chuck in the cylindrical container advances and retreats according to the screwing mechanism and the rotation stopping mechanism, the rotation torque acting on the shaft body of the core chuck constituting the rotation stopping mechanism is provided. Is not transmitted to the chuck because the shaft and the chuck for gripping the stick-shaped cosmetic are rotatably connected.
[0009]
Here, as a preferable configuration for sufficiently exhibiting the function of the rod-shaped cosmetic material feeding container, specifically, a cylindrical container has a screw cylinder provided with a screwing projection on an inner peripheral surface on a rear side inside the cylinder. Are mounted to be rotatable relative to each other, the shaft portion of the core chuck is inserted into the screw tube, and has a spiral groove on its outer peripheral surface for engaging with the screwing projection of the screw tube, and a concave groove as an engaging portion. Along the axial direction, the cylindrical container has an engagement piece that engages with the recessed groove of the shaft body portion between the retreat limit position of the chuck portion on the inner peripheral surface and the tip of the screw cylinder, The screwing projection of the screw cylinder and the spiral groove of the shaft portion constitute a screwing mechanism, and the engaging piece of the cylindrical container and the concave groove of the shaft portion constitute a rotation stopping mechanism.
[0010]
Further, the chuck portion includes a plurality of gripping pieces for gripping the rod-shaped cosmetic, the outer diameter of the gripping piece is larger than the outer diameter of the screw tube, and the screw tube is mounted in the tube container. The inner diameter of the area where the gripping piece advances and retreats is made larger than the inner diameter of the area, and the concave groove of the shaft body is recessed from the tip of the shaft body to a predetermined position along the axial direction and the gripping piece is formed. The rear end face against which the engaging piece abuts during forward movement is a stopper for limiting the advancement of the gripping piece, and the cylindrical container is capable of moving the gripping piece in a range from the opening at the tip where the rod-shaped cosmetic material appears and retracts to the retreat limit of the gripping piece. It is preferable that the holes have a hole shape.
[0011]
In this way, if the recessed groove of the shaft portion is recessed only up to a predetermined position along the axial direction from the tip of the shaft portion to function as the advance limit of the gripping piece, the shaft portion is removed. Insertion from the opening at the front end of the cylindrical container is not possible because the rear end of the shaft portion abuts an engaging piece provided in the middle of the cylindrical container. Therefore, the shaft portion is inserted from the opening at the rear end of the cylindrical container. At this time, the outer diameter of the gripping piece is larger than the outer diameter of the screw cylinder in order to apply the large-diameter rod-shaped cosmetic. Since the inner diameter of the area in which the gripping piece advances and retreats is larger than the inner diameter of the area in which the screw cylinder is mounted in the cylindrical container, the shaft body portion provided with the gripping piece at the tip end has a cylindrical shape. It is not allowed to insert through the opening at the rear end of the container. However, in the present invention, as described above, since the chuck portion having the holding piece and the shaft portion are rotatably connected to each other, they are separate bodies before assembly, and in addition, the rod-shaped makeup of the cylindrical container is additionally required. Since the range from the opening at the tip where the material appears and retracts to the retreat limit of the gripping piece is a hole shape that allows the gripping piece to move, the chuck part is inserted from the opening at the tip of the cylindrical container, By inserting the shaft portion from the opening at the rear end of the cylindrical container and assembling them so as to be rotatable, the rod-shaped cosmetic dispensing container having the above configuration is obtained.
[0012]
Here, in the cylindrical container, between the retreat limit position of the gripping piece and the tip of the screw cylinder, an intermediate area smaller than the inner diameter of the area where the gripping piece advances and retreats and the inner diameter of the area where the screw cylinder is mounted. Is set in this intermediate area, if an engaging piece that engages with the concave groove is protrudingly provided, an area where the gripping piece in the cylindrical container advances and retreats, and the area that is continuous with the area and has an inner diameter of the area. Since the inner peripheral step formed at the boundary with the intermediate region having a small inner diameter functions as a stopper for retreating the gripping piece, it is preferable to adopt this configuration.

As shown in FIG. 6, the engagement cylindrical portion 7e of the chuck portion 7a is provided with an annular groove portion 7g at the rear end position on the inner periphery thereof for rotatably mounting the core chuck shaft 7b.
[0047]
As shown in FIG. 7, the core chuck shaft 7b has a small-diameter shaft 7r at the tip thereof. As shown in FIG. 6, the small-diameter shaft 7r is inserted into the engagement cylinder 7e of the chuck portion 7a. The annular projection 7h formed on the outer periphery of the cylindrical member 7 engages with the annular groove 7g of the engagement cylinder 7e, whereby the chuck portion 7a is rotatably mounted on the core chuck shaft 7b.
[0048]
As shown in FIG. 7, the core chuck shaft 7b includes a spiral groove 7m forming a screwing mechanism from the vicinity of the front end to the rear end thereof. As shown in FIG. 4 and FIG. 6, concave grooves (engaging portions) 7n constituting the reciprocating guide mechanism are provided at 180 ° symmetrical positions with respect to the axis.
[0049]
As shown in FIG. 6, the core chuck shaft 7b is inserted into the screw tube 8, the spiral groove 7m is engaged with the screwing projection 8a of the screw tube 8, and the concave groove 7n is inserted into the cartridge tube. 6 are engaged with the engagement pieces 6p of the intermediate region 6j. As shown in FIG. 7, the recessed groove 7n has a rear end face 7q against which the engagement piece 6p abuts set as a forward end stopper of the core chuck 7 (gripping piece 7d).
[0050]
When assembling the stick-shaped cosmetic supply container 1 having such a configuration, first, the stick-shaped cosmetic cartridge 2 is assembled as a unit.
[0051]
Here, as described above, the concave groove 7n of the core chuck shaft 7b is recessed only to a predetermined position along the axial direction from the tip of the core chuck shaft 7b in order to function as a stopper for advancing the gripping piece 7d. Since the core chuck shaft 7b does not reach the rear end surface, the insertion of the core chuck shaft 7b from the opening at the front end of the cartridge cylinder 6 prevents the rear end surface of the core chuck shaft 7b from being inserted into the intermediate region 6j on the way in the cartridge cylinder 6. This is not possible because it comes into contact with the provided engaging piece 6p.
[0052]
Therefore, the core chuck shaft 7b is inserted from the opening at the rear end of the cartridge cylinder 6. At this time, the outer diameter of the gripping piece 7d of the chuck portion 7a is applied in order to apply the large-diameter rod-shaped cosmetic M. Is larger than the outer diameter of the screw cylinder 8 and the inner diameter of the advance / retreat hole 6i (the rod-shaped cosmetic material hole 6m + the advance / retreat groove 6n) is larger than the inner diameter of the screw cylinder housing hole 6k of the cartridge cylinder 6. Therefore, it is impossible to insert the core chuck shaft 7b having the gripping piece 7d at the front end from the opening at the rear end of the cartridge cylinder 6.
[0053]
However, in the present embodiment, as described above, the chuck portion 7a having the gripping piece 7d and the core chuck shaft 7b are rotatably connected to each other. The range from the opening at the tip of the cylinder 6 where the rod-shaped cosmetic material M appears and disappears to the retreat limit of the gripping piece 7d (the range of formation of the retreating hole 6i) is a hole shape that allows the gripping piece 7d to move.
[0054]
Therefore, the chuck portion 7a is inserted into the opening at the front end of the cartridge cylinder 6 from the side of the engagement cylinder portion 7e on the rear end side such that the gripping piece 7d and the advance / retreat groove 6n of the cartridge cylinder 6 are aligned. Then, after the core chuck shaft 7b is engaged (screwed) with the screw cylinder 8, the core chuck shaft 7b and the screw cylinder 8 are connected to the recessed groove 7n and the cartridge cylinder 6 from the small-diameter shaft 7r on the distal end side. The cartridge tube 6 is inserted into the opening at the rear end of the cartridge tube 6 so that the engagement piece 6p is fitted, and the outer peripheral step 8z of the screw tube 8 is brought into contact with the rear end surface of the cartridge tube 6. The annular projection 8c of the screw cylinder 8 is engaged with the annular groove 6h, and the screw cylinder 8 engaged with the core chuck shaft 7d is mounted on the cartridge cylinder 6 so as to be relatively rotatable and immovable in the axial direction. The engagement cylinder 7e of the chuck 7a is By pushing into the small diameter shaft 7r of the shaft 7a, the annular groove 7g of the engagement cylinder portion 7e and the annular projection 7h of the small diameter shaft 7r are engaged, and the chuck portion 7a and the core chuck shaft 7b are relatively rotatably connected. Is done.
[0055]
Next, the rod-shaped cosmetic cartridge 2 is obtained by inserting the rod-shaped cosmetic material M into the opening at the distal end of the cartridge tube 6 from the base end side and holding the chuck portion 7a of the core chuck 7.
[0056]
As described above, since the chuck portion 7a and the core chuck shaft 7b are connected to each other so as to be rotatable relative to each other and are separate bodies before assembly, the rod-shaped cosmetic cartridge 2 containing the large-diameter rod-shaped cosmetic M can be easily obtained. It is supposed to be.
[0057]
Next, the middle tool 20 is inserted into the opening at the tip of the cartridge housing container 3 from the rear end side, and the annular flange portion 20a is brought into contact with the step hole 3d of the cartridge housing container 3, so that the annular projection portion 20b is inserted into the cartridge housing container 3. The inner tool 20 is attached to the cartridge container 3 by engaging with the annular groove 3e of the third cartridge 3.
[0058]
Next, the stick-shaped cosmetic cartridge 2 is inserted from the rear end side into the opening at the distal end of the cartridge container 3 via the middle member 20, and the outer peripheral step 6 b of the cartridge cylinder 6 is abutted against the leading end surface of the middle member 20. As a result, the annular groove 6d of the cartridge cylinder 6 is engaged with the annular projection 20c of the middle tool 20, and the cartridge cylinder 6 is relatively rotatably and detachably mounted on the cartridge accommodating container 3 via the middle tool 20. Each of the vertical ribs 8b of the screw cylinder 8 is engaged with the upper vertical rib 3y of the cartridge storage container 3, and the screw cylinder 8 is non-rotatably connected to the cartridge storage container 3, so that the stick-shaped cosmetic feed container 1 is can get.
[0059]
As described above, in the present embodiment, since the rod-shaped cosmetic cartridge 2 is assembled as a unit and then attached to the cartridge accommodating container 3, the assembly of the rod-shaped cosmetic feeding container 1 is facilitated, and the manufacturing cost is reduced. It is planned.
[0060]
Here, when the rod-shaped cosmetic material feeding container 1 is dropped on, for example, a floor or the like, an impact external force is applied to the container 1. However, for the rod-shaped cosmetic cartridge 2, the inner tool 20 made of synthetic resin or the like is used. In addition to the flexibility, the notch 20d of the inner tool 20 is compressed to provide a cushioning property that allows the axial movement and the rotation of the notch 20d. Is hardly transmitted, so that no external force is transmitted to the core chuck 7, and the stick-shaped cosmetic M held by the chuck portion 7 a of the core chuck 7 is prevented from falling off or being damaged.
[0061]
Next, a case where the stick-shaped cosmetic material M is applied by the stick-shaped cosmetic material feeding container 1 will be described. In this case, the large diameter portion 6a exposed from the cartridge housing container 3 and the middle tool 20 of the cartridge cylinder 6 is picked, and the cartridge housing container 3 is picked up, and these are relatively rotated. Here, description will be made assuming that the cartridge housing container 3 is rotated.
[0062]
Then, since the upper vertical ribs 3y of the cartridge container 3 and the respective vertical ribs 8b of the screw tube 8 are engaged in the rotational direction, the screw tube 8 rotates integrally with the cartridge container 3. At this time, the cartridge container 3 is rotated against the rotational resistance between the engaging projection 8h of the screw cylinder 8 and the cartridge cylinder 6 which are non-rotatably connected thereto.
[0063]
At this time, in the core chuck 7 having the spiral groove 7m engaged with the screwing projection 8a of the screw cylinder 8, the recessed groove 7n has an engagement piece as a rotation stopping mechanism and an advance / retreat guide mechanism of the cartridge cylinder 6. Since it is engaged with 6p so as to be non-rotatable and axially movable, the rod-shaped cosmetic material M is advanced from the front end of the cartridge tube 6, and advances in the cartridge tube 6.
[0064]
At the time of this forward movement, the rotating torque by the engagement piece 6p acts on the concave groove 7n of the core chuck 7, but the rod-shaped cosmetic M is gripped by the core chuck shaft 7b having the concave groove 7n. Since the chuck portion 7a provided with the gripping piece 7d to be rotatably connected is rotatably connected, this rotational torque is interrupted at the connection portion and is not transmitted to the chuck portion 7a. Has been prevented.
[0065]
Then, when the stick-shaped cosmetic M is fed out to a desired length, the relative rotation between the cartridge housing container 3 and the cartridge tube 6 is stopped. Then, according to the rotational resistance generated between the engaging projection 8h of the screw cylinder 8 non-rotatably connected to the cartridge housing container 3 and the cartridge housing 6, the cartridge housing container 3 and the cartridge housing 6 are brought into a predetermined position. The engagement state is maintained.
[0066]
Therefore, in this state, the user may hold the cartridge container 3 and apply the stick-shaped cosmetic M. At this time, an external force acts on the cartridge cylinder 6 from the application surface via the rod-shaped cosmetic M and the rotation stopping mechanism, but the rotation of the cartridge cylinder 6 is prevented by the rotation resistance.
[0067]
Here, when the cartridge container 3 and the cartridge cylinder 6 are further rotated relative to each other, the rear end face 7q of the recessed groove 7n of the advancing core chuck shaft 7b abuts against the rear end face of the engagement piece 6p of the cartridge cylinder 6, and As a result, the lead chuck 7 reaches the forward limit, and further advance is prevented, and the lead is extended to the maximum.
[0068]
In this state, when the relative rotation is further continued, the cartridge chuck 6 is pressed by the core chuck 7 to move forward, and the cartridge cylinder 6 tries to move forward, and engages with the cartridge cylinder 6. The notch 20d of the middle tool 20 is compressed toward the front end side via the rear end side of the middle tool 20 that is in use.
[0069]
Then, the rod-shaped cosmetic cartridge 2 including the screw tube 8 is moved toward the distal end by the amount of the compression of the notch hole 20d of the middle tool 20, and the inclined surface 3c of the vertical rib 3y at the upper stage of the cartridge container 3 is moved to the screw tube. 8, the inclined surface 8d of the vertical rib 8b is pushed out to the tip end side, whereby the engagement state between the vertical ribs 3y and 8b is released, and the rotation of the cartridge container 3 is shut off with respect to the screw cylinder 8. In this manner, the inclined ribs 3c and 8d provided on the upper vertical rib 3y of the cartridge container 3 and the vertical rib 8b of the screw cylinder 8 serve as a torque limiter.
[0070]
Further, when the relative rotation is stopped in a state where the engagement between the vertical ribs 3y and 8b is released, an elastic force due to the stoppage of the compression of the notch hole 20d of the middle tool 20 is generated on the rear side of the middle tool 20, and the rod-shaped cosmetic material The cartridge 2 is moved to the rear end side, and the vertical rib 8b of the screw cylinder 8 and the vertical rib 3y of the cartridge container 3 return to the engaged state.
[0071]
When the application is completed, the user rotates the cartridge container 3 and the cartridge tube 6 relatively in the opposite direction to the above, so that the stick-shaped cosmetic M is drawn into the cartridge tube 6.
[0072]
At this time, as in the case of the forward movement, the rotational torque acting on the concave groove 7n of the lead chuck 7 from the engagement piece 6p is because the lead chuck shaft 7b and the chuck portion 7a are rotatably connected. It is not interrupted at the connection portion and is not transmitted to the chuck portion 7a, and the damage of the stick-shaped cosmetic M is prevented.
[0073]
Here, in the rod-shaped cosmetic cartridge 2, when the rod-shaped cosmetic cartridge 2 is pulled in the axial direction with a predetermined force while holding the cartridge storage container 3, the annular groove 6d of the cartridge cylinder 6 is Since the rod-shaped cosmetic cartridge 2 is detached from the annular projection 20c and can be withdrawn from the cartridge accommodating container 3, when the rod-shaped cosmetic M needs to be replaced due to exhaustion or the like, the rod-shaped cosmetic M is thus replaced. The cosmetic cartridge 2 may be withdrawn from the cartridge container 3 and the replacement (new) rod-shaped cosmetic cartridge 2 may be mounted on the cartridge container 3 in the same manner as described above, thereby improving convenience and practicality. I have. Further, since the stick-shaped cosmetic cartridge 2 is detachable from the cartridge accommodating container 3 in this manner, the stick-shaped cosmetic cartridge 2 that has been pulled out can be applied by holding the stick-shaped cosmetic cartridge 2 or the stick-shaped cosmetic cartridge 2 can be removed. It is also possible to advance and retreat the stick-shaped cosmetic M by picking up the cartridge tube 6 and the gear portion 8y at the rear end of the screw tube 8 as a feed-out container, and improving the versatility, convenience and practicality. Is further planned.
[0074]
As described above, in the present embodiment, a component of the rotation stopping mechanism of the core chuck 7 is provided as a recessed groove 7n on the core chuck shaft 7b, and the core chuck shaft 7b and the rod-shaped cosmetic M are combined. Since the chuck 7a to be gripped is connected to the chuck 7a so as to be relatively rotatable, the rotational torque acting on the recessed groove 7n generated when the core chuck 7 advances and retreats according to the screwing mechanism and the rotation stopping mechanism is transmitted to the chuck 7a. Therefore, it is possible to prevent the bar-shaped cosmetic M from being damaged.
[0075]
In addition, since the gripping piece 7d does not constitute a rotation stopping mechanism, it is possible to make the gripping piece 7d thinner and shorter, and to reduce the size of the stick-shaped cosmetic feeding container 1. .
[0076]
As described above, the present invention has been specifically described based on the embodiment. However, the present invention is not limited to the above embodiment. For example, in the above embodiment, the cross-sectional shape Although the application is described, it is also applicable to a bar-shaped cosmetic having a cross section of, for example, an elliptical shape.
[0077]
In the above-described embodiment, the stick-shaped cosmetic cartridge 2 is made detachable from the cartridge accommodating container 3 as the most preferable form in consideration of ease of assembly, replacement of the stick-shaped cosmetic M, and the like. Of course, it is also good to fix it to impossible.
[0078]
The configuration of the stick-shaped cosmetic feeding container is not limited to the above-described embodiment, and includes, for example, a cylindrical container having a substantially cylindrical shape and having a long hole along the axial direction in a peripheral wall on the rear side, and a rod-shaped container. A core chuck that holds the cosmetic and is inserted into the cylindrical container so as to be able to advance and retreat, and a spiral groove is formed on the inner peripheral surface, and is inserted outside the cylindrical container at the rear side so as to cover the elongated hole and is rotated by the cylindrical container. A screw cylinder that is freely mounted, and a screwing projection projecting from the rear side of the core chuck is loosely fitted into and engaged with the long hole of the cylindrical container. And a rotation stopping mechanism, and a tip of the screwing projection is engaged with a spiral groove of the screw cylinder to form a screwing mechanism. When the cylinder container and the screw cylinder are relatively rotated, the screwing mechanism is formed. The lead chuck advances and retreats according to the advance / retreat guide mechanism and the rotation stopping mechanism, and is held by the lead chuck. It is in the stick-shaped cosmetic material and is also applicable to the stick-shaped cosmetic material feeding container infested from the tip of the cylindrical vessel.
[0079]
【The invention's effect】
The stick-shaped cosmetic feeding container according to the present invention is generated when the core chuck in the cylindrical container advances and retreats according to the screwing mechanism and the rotation stopping mechanism, and generates a rotating torque acting on the shaft body of the core chuck constituting the rotation stopping mechanism. By rotatably connecting the shaft portion and the chuck portion for gripping the rod-shaped cosmetic material, the shaft member portion is configured not to be transmitted to the chuck portion, so that damage to the rod-shaped cosmetic material can be prevented. At the same time, the chuck portion can be made thinner and shorter, and the feeding container can be reduced in size.
