Description

【０００１】
【発明が属する技術分野】
この発明は、化粧料、特にコーンシーラー、アイシャドウ、アイブロー、マスカラ等の液体化粧料に使用される液体化粧料容器の構造に関する。
【０００２】
【従来の技術】
従来、化粧料、特にコーンシーラー、アイシャドウ、アイブロー、マスカラ等の液体化粧料に使用される液体化粧料容器において、当該液体化粧料容器の容器本体内に貯留する液体化粧料を塗布するために使用する塗布体を一体に内装するキャップは、当該容器本体に一体となるよう構成され、外表面に雄ネジを配設する筒状の雄ネジ部と、当該キャップ内に内設される雌ネジ部とを螺合させることにより、当該容器本体と一体となるものである。そして、この容器本体とキャップとを一体とする容器本体の雄ネジ部は、使用に際してキャップに一体に内装される塗布体に余分に付着した液体化粧料を拭えるようにシゴキ等が必要であることから、容器本体に一体に形成された口筒部に対して、雄ネジ体、シゴキ体等の複数の部品をカバー体を該口筒部にカシメて固定することにより構成されているものが一般的である。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来の液体化粧料容器の雄ネジ部は、容器本体に一体に形成された口筒部に対して、雄ネジ体、シゴキ体等の複数の部品をカバー体を該口筒部にカシメて固定するだけのものであるから、この雄ネジ部に対して一体となるキャップを反復して開け閉めすることで繰り返し大きな負荷が加わると、該口筒部のカシメにおいて緩みが生じやすく、当該雄ネジ部を構成する複数の部品を一体にカシメて固定している力が失われやすいという欠点を有するものである。このため、液体化粧料を塗布する際に、容器本体内に貯留する液体化粧料が僅かでも当該雄ネジ部に付着し、この雄ネジ部に付着した液体化粧料が乾燥固化したり、またキャップを当該雄ネジ部に締め込む際に当該キャップの雌ネジ部が雄ネジ部の終端に達しているにもかかわらず、更に強く締め込むことでキャップの雌ネジ部と該雄ネジ部とが互いにそのネジを噛み込みながら変形すること等によりキャップと雄ネジ部とが一体に固着してしまうと、再度キャップを取り外そうとしても、キャップは容器本体の雄ネジ部と共に一体となって共回りしてしまい、最終的にはキャップを取り外すことができなくなるというおそれがある。
【０００４】
そこで、上記従来の液体化粧料容器に対して、上記キャップを螺合させる雄ネジ部を、容器本体の口筒部に対して、カバー体である金属リングにより、雄ネジ体である筒部材及びシゴキ部材を固定してなるものであって、該筒部材には、互いに対向して位置するように一対の係止脚部を設けると共に、口筒部の上部部分に、平坦面からなる係止部を互いに周方向に１８０度離間して設けてなるものであって、該筒部材の係止脚部を口筒部の上部部分の係止部に係合させた上で、金属リングを口筒部の上部部分を含めシゴキ部材と筒部材に被せ、その金属リングの下端を口筒部の上部部分の下方に巻き付けるようにカシメてなるものが提案されている（特開平９−３０８５２４号）。
【０００５】
上記特開平９−３０８５２４号の場合は、確かにキャップが螺合する雄ネジ部を構成する筒部材は、口筒部の上部部分に互いに周方向に１８０度離間して設けてなる平坦面からなる係止部に対して、該筒部材の係止脚部を口筒部の上部部分の係止部に係合させた上で金属リングを被せて固定するものであるので、付着した液体化粧料の乾燥固化や過剰な締め込みによるネジの噛み込みよりキャップと雄ネジ部とが一体に固着してしまっても、キャップに大きな荷重をかけることで、上記筒部材の係止脚部と口筒部の上部部分の係止部との係合によってこのキャップに係る大きな荷重を受けることとなるので、両者が共回りすることはなく、キャップと雄ネジ部を構成する筒部材との固着を確実に解いて、キャップを容器本体の雄ネジ部から取り外すことができるものである。
しかし、雄ネジ部を構成する筒部材及びシゴキ部材を容器本体の口筒部に対して固定するにあたっては、従来の液体化粧料容器と同様に、金属リングの下端を口筒部の上部部分の下方に巻き付けるように単にカシメて固定しているだけなので、金属リングを容器本体の口筒部に対して固定する力は従来と変わらず、付着した液体化粧料の乾燥固化によるキャップと金属リング自体との固着や、反復してキャップの過剰な締め込みが行われることにより生じる筒部材のねじ部とキャップとが噛み込むことによる強固な固着を解くために、その固着したキャップを介して当該金属リングの口筒部の上部部分の下方に対するカシメに直接的又は間接的に過大な荷重が加わると、金属リングの下端を口筒部の上部部分の下方に巻き付けるようにカシメている部分に緩みが発生すると共に、次第に筒部材の係止脚部と口筒部の上部部分の係止部との係合にも変形が生じて、筒部材の係止脚部と口筒部の上部部分の係止部との係合にも緩みが生じるものとなる。従って、金属リングによる容器本体の口筒部に対する筒部材及びシゴキ部材の固定が不十分となって緩みが生じると、上記雄ネジ部を構成する筒部材及びシゴキ部材間にガタが生じ、キャップの脱着を円滑に行うことができない上、液体化粧料の漏出等の不具合を招いてしまうこともある。
【０００６】
そこで、この発明は上記従来のものの有する問題を解決するものであり、キャップを脱着する化粧料容器本体の雄ネジ部において、この雄ネジ部を構成する各部品を確実に固定し、キャップと該雄ネジ部との固着を防ぎつつ円滑且つ確実ななキャップの脱着を確保することができるようにする。
【０００７】
【課題を解決するための手段】
そのために、内部に液体化粧料を貯留すると共に、その上部に内部に連通する孔部を有する雄ネジ部を付設する化粧料容器本体と、該化粧料容器本体内部に貯留する液体化粧料を塗布するために使用する塗布体を一体に内装し、該化粧料容器本体の上部に付設する雄ネジ部に対して、その内側に配設される雌ネジ体を以て螺合させることで化粧料容器本体と一体になるキャップからなり、
当該化粧料容器本体の上部においてキャップを螺合させるため付設する雄ネジ部は、カバー体、雄ネジ体、シゴキ体及び化粧料容器本体の上部に一体に形成される口筒部から構成され、
該雄ネジ部を構成するカバー体は中空円筒体であって、その上端には、中央を開口し、該開口部の周縁を例えば、多角形係合部又は半径外方向に向かう係合凹部等の係合部としてなる蓋部が設けられるとともに、下端は開口した上、下端縁から係止凹リブを上方向に設けてなるものであり、
該雄ネジ部を構成する雄ネジ体は、外表面に雄ネジを螺設するとともにカバー体の開口部を貫通する中空のネジ体円筒部の下端に、前記カバー体の蓋部下面と当接するフランジを有するものであって、このフランジ上に上記カバー体の開口部周縁に設けられる例えば、多角形係合部又は半径外方向に向かう係合凹部等の係合部と係合する例えば多角形被係合部又は半径外方向に突出して設けられる係合凸部等の被係合部を設けてなるものであり、
該雄ネジ部を構成するシゴキ体は、前記雄ネジ体のネジ体円筒部に下側から挿嵌する中空の円筒部の下端にフランジを有するとともに、当該円筒部内部に舌片状のシゴキを配置してなるものであり、
該雄ネジ部を構成し、化粧料容器本体に一体に形成される口筒部は、化粧料容器本体内に連通するように孔部を有する円筒状であって、該円筒状の口筒部上部において、前記雄ネジ体及びシゴキ体の各フランジを上面において係止する径大部を設けると共に、上記カバー体の係止凹リブと係合する係止凸リブを該径大部下縁に下方向に向けて突出するように設けてなるものであって、
ネジ体円筒部がカバー体の下側より蓋部の開口部を貫通して上方へ突出するとともに、フランジ上に設ける被係合部が該開口部周縁に設ける係合部と係合する雄ネジ体と、円筒部が該雄ネジ体のネジ体円筒部の下側から挿嵌されたシゴキ体とが、化粧料容器本体に一体に形成される口筒部上部の径大部の上面によってその各フランジを係止されるとともに、下端縁に設けられた係止凹リブが口筒部の径大部下縁に設けられた係止凸リブに嵌合して係止されつつ、該径大部下縁に対してその下端をカシメられるカバー体により、化粧料容器本体に形成される口筒部と一体となって、上記雄ネジ部を構成してなるものである。
【０００８】
また、内部に液体化粧料を貯留すると共に、その上部に内部に連通する孔部を有する雄ネジ部を付設する化粧料容器本体と、当該化粧料容器本体内部に貯留する液体化粧料を塗布するために使用する塗布体を一体に内装し、当該化粧料容器本体の上部に付設する雄ネジ部に対して、その内側に配設される雌ネジ体を以て螺合させることで化粧料容器本体と一体になるキャップからなり、
当該化粧料容器本体の上部においてキャップを螺合させるため付設する雄ネジ部は、カバー体、雄ネジ体、シゴキ体及び化粧料容器本体の上部に一体に形成される口筒部から構成され、
該雄ネジ部を構成するカバー体は多角形筒体であって、その上端には、中央に開口部を設けた蓋部が設けられるとともに、下端は開口してなるものであり、
該雄ネジ部を構成するネジ体は、外表面に雄ネジを螺設するとともにカバー体の開口部を貫通する中空のネジ体円筒部の下端にフランジを有するものであって、このフランジの外周縁を上記多角形筒体であるカバー体の内壁面と係合する同形状の多角形被係合部とするものであり、
該雄ネジ部を構成するシゴキ体は、前記雄ネジ体のネジ体円筒部に下側から挿嵌する中空の円筒部の下端にフランジを有するとともに、当該円筒部内部に舌片状のシゴキを配置してなるものであり、
該雄ネジ部を構成し、化粧料容器本体に一体に形成される口筒部は、化粧料容器本体内に連通するように孔部を有する筒状であって、該筒状の口筒部上部において、外側へ肉厚となって、前記雄ネジ体及びシゴキ体の各フランジを上面において係止するとともに、前記多角形筒体であるカバー体の内壁面と係合する同形状の多角形被係合部を形成してなるものであって、
ネジ体円筒部がカバー体の下側より蓋部の開口部を貫通して上方へ突出するとともに、フランジに設ける多角形被係合部が該カバー体の多角形状の内壁面と係合する雄ネジ体と、円筒部が雄ネジ体のネジ体円筒部の下側から挿嵌されたシゴキ体とが、化粧料容器本体に一体に形成される口筒部上部の外側へ肉厚となった多角形被係合部の上面によってその各フランジを係止されるとともに、該多角形被係合部とその内壁面とが係合しつつ、該多角形被係合部下縁に対してその下端をカシメられるカバー体により、化粧料容器本体に形成される口筒部と一体となって、上記雄ネジ部を構成してなるものである。
【０００９】
【発明の実施の形態】
この発明の実施において、化粧料容器本体の雄ネジ部おいて、カバー体と雄ネジ体は、カバー体の開口部周縁に設けられる、例えば多角形係合部又は半径外方向に向かう係合凹部等の係合部と、ネジ体のフランジ上に設ける例えば多角形被係合部又は半径外方向に突出して設けられる係合凸部等の被係合部とを係合させることで一体となるものであり、更にカバー体は雄ネジ体とシゴキ体を覆いつつ、口筒部の径大部下縁にカバー体の下端縁をカシメて、該カバー体の下端縁に設けられた係止凹リブを口筒部の径大部下縁に設けられた係止凸リブに係合させるものであるので、キャップと雄ネジ部を構成する雄ネジ体とが、液体化粧料の乾燥固化やネジ部の噛み合いによる変形によって固着した時に、このキャップと雄ネジ部との固着を解くべくキャップに対して大きな荷重をかけても、化粧料容器本体の雄ネジ部をシゴキ体と共に構成するカバー体、雄ネジ体及び化粧料容器本体に形成される口筒部とは、互いにカバー体の係合部と雄ネジ体の被係合部との係合及びカバー体の下端縁の係止凹リブと口筒部の径大部下縁に設けられる係止凸リブとの係合により、一体に強固に固定されているので、キャップを介しての大きな荷重を化粧料容器本体のシゴキ体を除く雄ネジ部全体で受けることができるものとなるので、キャップと雄ネジ体は共回りすることはなく、化粧料容器本体の雄ネジ部とキャップの固着を確実に解き、しかもカバー体のカシメ部分に対する過大な荷重の負荷を防止して、円滑にキャップを脱着することができる。
【００１０】
また、化粧料容器本体の雄ネジ部を構成するカバー体、雄ネジ体のフランジ及び化粧料容器本体に一体に形成される口筒部上部を同形状である多角形形状とした上で、化粧料容器本体に一体に形成される口筒部上部の外側へ肉厚となった口筒部上部の多角形被係合部上面に対して係止される雄ネジ体及びシゴキ体が、カバー体の内壁面を口筒部上部の多角形被係合部に係合させつつ、該多角形被係合部下縁に対してカシメて雄ネジ部を構成するものとすることで、キャップと雄ネジ部を構成するネジ体とが液体化粧料の乾燥固化やネジ部の噛み合いによる変形によって固着した時に、このキャップと雄ネジ部との固着を解くべくキャップに対して大きな荷重をかけても、この大きな荷重を化粧料容器本体のシゴキ体を除く雄ネジ部全体によって受けるものとなるので、キャップと雄ネジ体は共回りすることはなく、化粧料容器本体の雄ネジ部とキャップの固着を確実に解き、しかもカバー体のカシメ部分に対する過大な荷重の負荷を防止して、円滑にキャップを脱着することができる。
【００１１】
【実施例】
この発明を図に示す実施例により更に説明する。（５２）はこの発明の実施例である液体化粧料容器であり、この液体化粧料容器（５２）は、その内部において、例えばコーンシーラー、アイシャドウ、アイブロー、マスカラ等の液体化粧料を貯留する化粧料容器本体（１）とキャップ（２５）とから構成される。
【００１２】
そして、図３は第１実施例の要部たる、化粧料容器本体（１）上部に付設される雄ネジ部（２）の分解斜視図であり、当該雄ネジ部（２）はカバー体（３）、雄ネジ体（４）、シゴキ体（５）及び化粧料容器本体（１）の上部に一体となって形成されている口筒部（６）とから構成されている。そして、カバー体（３）は中空の円筒体であって、その上部には、中央部分を正八角形に開口して開口部（７）とした蓋部（８）が設けられ、この蓋部（８）の開口部（７）端縁は正八角形の係合部（９）となっている。又、カバー体（３）の下部は開放された上、下端縁には１８０度対象の位置に２個、それぞれ上方向への係止凹リブ（１０）が設けられている。次に、雄ネジ体（４）は、前記カバー体（３）の蓋部（８）に設けられた開口部（７）を貫通する中空のネジ体円筒部（１１）の下方に、前記カバー体（３）の蓋部（８）に設けられた開口部（７）によって形成された正八角形の係合部（９）と間隙を有することなく係合する、外縁が正八角形状の被係合部（１２）が設けられ、更にその下方に、カバー体（３）の蓋部（８）下面とその上面が当接し、又、口筒部（６）上部の径大部（２１）上面とその下面が当接するフランジ（１３）が設けられている。又、ネジ体円筒部（１１）の外表面には雄ネジ（１４）が螺設されている。そして、ネジ体円筒部（１１）内部には、シゴキ体（５）の円筒部（１７）を係止する係止段部（１５）が設けられ、又、フランジ（１３）の下面には、同じくシゴキ体（５）のフランジ（１８）を係止するフランジ係止段部（１６）が設けられる。次に、シゴキ体（５）は、前記雄ネジ体（４）のネジ体円筒部（１１）内に下側から挿嵌される中空の円筒部（１７）の下方に、前記カバー体（３）のフランジ（１３）に設けられたフランジ係止段部（１６）に係合するとともに、その下面が口筒部（６）上部の径大部（２１）上面と当接するフランジ（１８）が設けられる。そして、中空の円筒部（１７）内部には、舌片状のシゴキ（１９）が設けられている。次に、口筒部（６）は化粧料容器本体（１）上部に円筒状に一体に形成され、化粧料容器本体（１）内部に連通する孔部（２０）を有するとともに、口筒部（６）上部に径大部（２１）が設けられている。そして、該径大部（２１）下縁には、前記カバー体（３）の下端縁に２個設けられた上方向への係止凹リブ（１０）とそれぞれ係合する２個の係止凸リブ（２２）が下方向へ突出して設けられる。
【００１３】
この発明の第１実施例の要部ため雄ネジ部（２）は以上のように構成されるので、その組み立てに当たっては、第１に、シゴキ体（５）の円筒部（１７）を、雄ネジ体（４）のネジ体円筒部（１１）に下側から挿嵌し、雄ネジ体（４）のフランジ（１３）下面に設けられたフランジ係止段部（１６）に、シゴキ体（５）のフランジ（１８）を係合させて係止する。第２に、これら一体となった雄ネジ体（４）とシゴキ体（５）を口筒部（６）の径大部（２１）上面に載置した上、それら雄ネジ体（４）とシゴキ体（５）の上方からカバー体（３）を、その開口部（７）を雄ネジ体（４）のネジ体円筒部（１１）に貫通させて設置する。そしてその際、カバー体（３）の蓋部（８）に設けられた開口部（７）によって形成された正八角形の係合部（９）と、雄ネジ体（４）に設けられた外縁が正八角形状の被係合部（１２）とを間隙を有することなく係合させる。又、同時に、カバー体（３）の下端縁に設けられた２個の係止凹リブ（１０）が、口筒部（６）の径大部（２１）下縁に設けられた２個の係止凸リブ（２２）にそれぞれ重ね合うように、位置を調整する。第３に、該カバー体（３）の係止凹リブ（１０）部分を除く下端を、口筒部（６）の径大部（２１）下縁に対してカシメてカシメ部（２３）が形成され、それぞれ重なり合う前記２個の係止凸リブ（２２）と２個の係止凹リブ（１０）とをそれぞれ係合させる。以上により、化粧料容器本体（１）の上部に付設される雄ネジ部（２）が形成される。
【００１４】
この結果、第１に、前記２対の係止凸リブ（２２）と係止凹リブ（１０）とが係合することにより、カバー体（３）は化粧料容器本体（１）と一体となった口筒部（６）に対して、雄ネジ体（４）のネジ体円筒部（１１）外表面に螺設された雄ネジ（１４）の正・逆両回転方向（以下、単に回転方向と言う。）に対して回転不能に固定されることとなる。第２に、雄ネジ体（４）に設けられた外縁が正八角形状の被係合部（１２）と、カバー体（３）の蓋部（８）に設けられた開口部（７）によって形成された正八角形の係合部（９）とが係合することにより、雄ネジ体（４）はカバー体（３）に対して、雄ネジ（１４）の回転方向に対して回転不能に固定されることとなる。又、その被係合部（１２）と係合部（９）との係合に際して、その両者が隙間なく係合するため、被係合部（１２）がカバー体（３）の蓋部（８）に設けられた開口部（７）に対するスペーサーを兼用することとなり、開口しているネジ体円筒部（１１）部分を除き、カバー体（３１）の開口部（７）を閉塞することとなる。
【００１５】
一方、化粧料容器本体（１）内部に貯留される液体化粧料を塗布するための塗布体（２４）を一体に有するキャップ（２５）は、その内壁面に、前記雄ネジ体（４）のネジ体円筒部（１１）外表面に螺設された雄ネジ（１４）に螺合する雌ネジ（２６）が螺設されている。これによってキャップ（２５）は、その一体となった塗布体（２４）を雄ネジ体（４）のネジ体円筒部（１１）、シゴキ体（５）の円筒部（１７）及びシゴキ（１９）、更には口筒部（６）の孔部（２０）にそれぞれ貫通させることによって、塗布体（２４）を化粧料容器本体（１）内部へ到達させつつ、前記雌ネジ（２６）が雄ネジ体（４）のネジ体円筒部（１１）外表面に螺設された雄ネジ（１４）に螺合して化粧料容器本体（１）と着脱自在に一体となっている。
【００１６】
このため例えば、キャップ（２５）内壁面に設けられた雌ネジ（２６）と、雄ネジ体（４）のネジ体円筒部（１１）外表面に螺設された雄ネジ（１４）とを強く固着し過ぎたり、あるいはその両者間に化粧料等が付着することによって、その両者の螺合の解除に強度の回転力を加える必要が生じた場合、そのキャップ（２５）に加えられた強度の回転力が、キャップ（２５）と直接、あるいは固着等した化粧料等を介して接するカバー体（３）に伝達されても、カバー体（３）は化粧料容器本体（１）と一体となった口筒部（６）に対して、雄ネジ体（４）のネジ体円筒部（１１）外表面に螺設された雄ネジ（１４）の回転方向に対して回転不能に固定されているため、キャップ（２５）の回転に供回りすることがない。そのため、カバー体（３）がキャップ（２５）の回転に供回りしようとすることによって生ずるカシメ部（２３）の緩みや、場合によっては供回りによってカシメ部（２３）に加わる不要な荷重により、カシメ部（２３）が変形する等して生ずるより大きなカシメ部（２３）の緩みは、発生する余地がなく、当該化粧料容器の使用に伴う雄ネジ部（２）のガタつきの発生を防止することができる。又、その際、キャップ（２５）と雄ネジ体（４）との供回りは、以下の通りカバー体（３）を介して当然防止される。すなわち、化粧料容器本体（１）と一体となった口筒部（６）に対してカバー体（３）が、前述の通り雄ネジ（１４）の回転方向に対して回転不能に固定され、更に、当該カバー体（３）の蓋部（８）に設けられた開口部（７）によって形成された正八角形の係合部（９）と雄ネジ体（４）に設けられた外縁が正八角形状の被係合部（１２）とが係合することにより、雄ネジ体（４）は雄ネジ（１４）の回転方向に対して回転不能に固定されているからである。
【００１７】
図４は、この発明の第２の実施例の要部たる、化粧料容器本体（１）上部に付設される雄ネジ部（２’）の分解斜視図であり、前記図３に示す第１実施例の要部とは、シゴキ体（５）及び口筒部（６）の形状は同一である。この実施例におけるカバー体（２７）は中空の円筒体であって、その上部には、１８０度対象の位置に半径外方向へそれぞれ切り欠いた２個の係合凹部（２８）を有する円形の開口部（２９）を中央部分に有する蓋部（３０）が設けられる。又、カバー体（２７）の下部は開放された上、下端縁には１８０度対象の位置に２個、それぞれ上方向への係止凹リブ（３１）が設けられ、それ以外の下端縁は、口筒部（６）の径大部（２１）下縁に対してカシメられるカシメ部（３２）となる。次に、雄ネジ体（３３）は、前記カバー体（２７）の蓋部（３０）に設けられた開口部（２９）を貫通する中空のネジ体円筒部（３４）の下方に、前記カバー体（２７）の蓋部（３０）に設けられた開口部（２９）及び係合凹部（２８）に隙間なく係合する、円形のスペーサー（３５）及びそれに付随して１８０度対象の位置に半径外方向へそれぞれ突出する係合凸部（３６）が設けられ、更にその下方に、カバー体（２７）の蓋部（３０）下面とその上面が当接し、又、口筒部（６）上部の径大部（２１）上面とその下面が当接するフランジ（３７）が設けられている。又、ネジ体円筒部（３４）の外表面には雄ネジ（３８）が螺設されている。そして、ネジ体円筒部（３４）内部には、前記第１実施例と同様に、シゴキ体（５）の円筒部（１７）を係止する係止段部（１５）が設けられ、又、フランジ（３７）の下面には、同じくシゴキ体（５）のフランジ（１８）を係止するフランジ係止段部が設けられる（図２の番号１６を参照）。
【００１８】
この発明の第２実施例の要部たる雄ネジ部（２’）は以上のように構成されるので、その組み立てに当たっても、前記第１実施例と同様に組み立てることができる。そして、第１実施例の場合と同様に、例えば、キャップ（２５）内壁面に設けられた雌ネジ（２６）と、雄ネジ体（３３）のネジ体円筒部（３４）外表面に螺設された雄ネジ（３８）とを強く固着し過ぎたり、あるいはその両者間に化粧料等が付着することによって、その両者の螺合の解除に強度の回転力を加える必要が生じた場合、そのキャップ（２５）に加えられた強度の回転力が、キャップ（２５）と直接、あるいは固着等した化粧料等を介して接するカバー体（２７）に伝達されても、カバー体（２７）は化粧料容器本体（１）と一体となった口筒部（６）に対して、前記２対の係止凸リブ（２２）と係止凹リブ（３１）とが係合することにより、雄ネジ体（３３）のネジ体円筒部（３４）外表面に螺設された雄ネジ（３８）の回転方向に対して回転不能に固定されているため、キャップ（２５）の回転に供回りすることがない。そのため、カバー体（２７）がキャップ（２５）の回転に供回りしようとすることによって生ずるカシメ部（３２）の緩みや、場合によっては供回りによってカシメ部（３２）に加わる不要な荷重により、カシメ部（３２）が変形する等して生ずるより大きなカシメ部（３２）の緩みは、発生する余地がなく、当該化粧料容器の使用に伴う雄ネジ部（２’）のガタつきの発生を防止することができる。又、その際、キャップ（２５）と雄ネジ体（３３）との供回りは、以下の通りカバー体（２７）を介して当然防止される。すなわち、化粧料容器本体（１）と一体となった口筒部（６）に対してカバー体（２７）が、前述の通り雄ネジ（３８）の回転方向に対して回転不能に固定され、更に、当該カバー体（２７）の蓋部（３０）に設けられた２個の係合凹部（２８）と、雄ネジ体（３３）のスペーサー（３５）に付随して設けられた２個の係合凸部（３６）とがそれぞれ係合することにより、雄ネジ体（３３）は雄ネジ（３８）の回転方向に対して回転不能に固定されているからである。、
【００１９】
図６は、この発明の第３の実施例の要部たる、化粧料容器本体（１’）上部に付設される雄ネジ部（２”）の分解斜視図であり、前記図３に示す第１実施例とは、シゴキ体（５）の形状は同一である。この実施例におけるカバー体（３９）は中空の正八角形の筒体（４０）であって、その上部には、中央部分を円形に開口して開口部（４１）とした蓋部（４２）が設けられている。又、カバー体（３９）の下部は開放されている。次に、雄ネジ体（４３）は、前記カバー体（３９）の蓋部（４２）に設けられた開口部（４１）を貫通する中空のネジ体円筒部（４４）の下方に、前記カバー体（３９）の蓋部（４２）に設けられた開口部（４１）に隙間無く装着されるスペーサー（４５）が設けられ、更にその下方に、カバー体（３９）の蓋部（４２）下面とその上面が当接し、又、口筒部（４８）上部の正八角形被係合部（５０）上面とその下面が当接するとともに、その外縁が正八角形状となって、前記カバー体（３９）の正八角形状の筒体（４０）と係合するフランジ（４６）が設けられている。又、ネジ体円筒部（４４）の外表面には雄ネジ（４７）が螺設されている。そして、ネジ体円筒部（４４）内部には、前記第１実施例と同様に、シゴキ体（５）の円筒部（１７）を係止する係止段部（１５）が設けられ、又、フランジ（４６）の下面には、同じくシゴキ体（５）のフランジ（１８）を係止するフランジ係止段部（１６）が設けられる。次に、口筒部（４８）は化粧料容器本体（１’）上部に筒状に一体に形成され、化粧料容器本体（１’）内部に連通する孔部（４９）を有するとともに、口筒部（４８）上部に外側へ肉厚となって、前記カバー体（３９）の正八角形状の筒体（４０）内壁面と係合する正八角形被係合部（５０）が設けられている。

[Technical field to which the invention belongs]
The present invention relates to a structure of a liquid cosmetic container used for cosmetics, particularly liquid cosmetics such as corn sealers, eye shadows, eyebrows, and mascaras.
[0002]
[Prior art]
Conventionally, in a liquid cosmetic container used for cosmetics, particularly liquid cosmetics such as corn sealer, eye shadow, eyebrow, mascara, etc., in order to apply the liquid cosmetic stored in the container body of the liquid cosmetic container The cap that integrally coats the application body to be used is configured to be integrated with the container body, and has a cylindrical male screw portion that has a male screw on the outer surface, and a female screw that is provided inside the cap. By screwing the part together, the container body is integrated. The male thread portion of the container main body in which the container main body and the cap are integrated requires a squeeze or the like so as to wipe off the liquid cosmetics that are excessively attached to the application body that is integrated with the cap in use. Therefore, what is constituted by caulking and fixing a plurality of parts such as a male screw body and a shigoki body to the mouth tube portion with respect to the mouth tube portion formed integrally with the container main body. It is common.
[0003]
[Problems to be solved by the invention]
However, the male thread portion of the conventional liquid cosmetic container is a cover body with a plurality of parts, such as a male thread body and a scabbard body, in the mouth tube section formed integrally with the container body. Since it is only caulking and fixing, when a large load is repeatedly applied by repeatedly opening and closing the cap integrated with this male screw part, loosening is likely to occur in the caulking of the mouth tube part, This has a drawback that the force of caulking and fixing a plurality of parts constituting the male screw portion is easily lost. For this reason, when the liquid cosmetic is applied, even a small amount of the liquid cosmetic stored in the container body adheres to the male screw part, and the liquid cosmetic attached to the male screw part dries and solidifies, or the cap Even if the female threaded portion of the cap reaches the end of the male threaded portion when tightening into the male threaded portion, the female threaded portion of the cap and the male threaded portion can be If the cap and male screw part are fixed together by deformation while the screw is being bitten, etc., the cap will rotate together with the male screw part of the container body even if the cap is removed again. As a result, the cap may not be removed in the end.
[0004]
Therefore, a male screw part for screwing the cap into the conventional liquid cosmetic container is formed of a cylindrical member that is a male screw body by a metal ring that is a cover body with respect to the mouth tube part of the container body, and The squeaker member is fixed, and the cylindrical member is provided with a pair of locking leg portions so as to be opposed to each other, and the upper portion of the mouth tube portion is locked with a flat surface. Parts are provided 180 degrees apart from each other in the circumferential direction, and after engaging the locking legs of the cylindrical member with the locking parts of the upper part of the mouth tube part, the metal ring is opened. It has been proposed to cover a squeeze member and a cylindrical member including the upper part of the cylindrical part and crimp the lower end of the metal ring below the upper part of the mouth cylindrical part (Japanese Patent Laid-Open No. 9-308524). .
[0005]
In the case of the above-mentioned Japanese Patent Laid-Open No. 9-308524, the cylindrical member that constitutes the male thread part to which the cap is surely screwed is formed from a flat surface that is provided 180 degrees apart in the circumferential direction from the upper part of the mouth cylinder part. Since the locking leg portion of the tubular member is engaged with the locking portion of the upper portion of the mouth tube portion and fixed with a metal ring, the attached liquid makeup Even if the cap and the male screw part are fixed together due to the screw being solidified or excessively tightened, a large load is applied to the cap, so that Since a large load related to this cap is received by engagement with the locking portion of the upper portion of the cylindrical portion, both of them do not rotate together, and the cap and the cylindrical member constituting the male screw portion are fixed. Unscrew securely and remove the cap from the male thread of the container body. It is those that can be removed.
However, in fixing the cylindrical member and the squeeze member constituting the male screw portion to the mouth tube portion of the container body, the lower end of the metal ring is connected to the upper portion of the mouth tube portion as in the conventional liquid cosmetic container. Since it is simply crimped and fixed so as to be wound downward, the force for fixing the metal ring to the mouth tube portion of the container body is the same as before, and the cap and metal ring itself by drying and solidifying the adhering liquid cosmetics In order to release the strong fixation caused by the screwing of the cylindrical member and the cap, which occurs when the cap is repeatedly tightened excessively and repeatedly, the metal is passed through the fixed cap. When an excessive load is applied directly or indirectly to the caulking of the upper part of the mouth part of the ring, the lower end of the metal ring is caulked to be wound below the upper part of the mouth part. And the engagement between the locking leg portion of the tubular member and the engaging portion of the upper portion of the mouth tube portion is also gradually deformed, and the locking leg portion and the mouth tube portion of the tube member are gradually deformed. The looseness also occurs in the engagement of the upper portion with the locking portion. Therefore, when the cylindrical member and the squeeze member are not sufficiently fixed to the mouth tube part of the container main body by the metal ring, looseness occurs, and a backlash occurs between the cylindrical member and the squeeze member constituting the male screw part. Desorption cannot be performed smoothly, and problems such as leakage of liquid cosmetics may occur.
[0006]
Therefore, the present invention solves the above-described problems of the conventional ones, and in the male screw portion of the cosmetic container body to which the cap is attached and detached, each component constituting the male screw portion is securely fixed, and the cap and the It is possible to ensure a smooth and reliable attachment / detachment of the cap while preventing the fixation with the male screw portion.
