Description

【０００１】
【産業上の利用分野】
本発明は、口紅、マニキュア、ファンデーション等の液状化粧料を収納し、それらを僅かづつ押し出すように先端部から注出して使用することのできる長筒状の液状化粧料注出容器に関するものである。
【０００２】
【従来の技術】
口紅やマニキュア等の液状化粧料を収納し、押し出し機構によってその液状化粧料を先端部である塗布部分から押し出すように注出し、唇等に塗布することのできる液状化粧料注出容器として、例えば、特開平７─２６５１２３号に開示のものがある。
【０００３】
この液状化粧料注出容器は、その押し出し機構を、雄螺子部と雌螺子部とで構成し、雄螺子部を回転させることによって雌螺子部を前方に移動させ、その前方移動によって液状化粧料を押し出して注出するものである。
【０００４】
この従来の液状化粧料注出容器にあって、雄螺子部の回転は、その後端部で、外筒より僅かに後方に突出した摘み部を、指先で回転させることによって達成するものとしており、またこの従来技術においては、小径の雄螺子部と、それより太径の雌螺子部の周壁との間に無用の空間が存在している。
【０００５】
さらに、当該従来技術にあっては、その後端部で、注出容器の軸心に位置する雄螺子部に設けた爪片と、雄螺子部の外周に位置する軸受け筒に設けた係止凹部とでラチェット機構を構成し、摘み部が一方向にのみ回転するように設定している。
【０００６】
【発明が解決しようとする課題】
この従来技術においては、前記した如く、液状化粧料の押し出し注出操作を、外筒より僅かに後方に突出した摘み部を指先で回転させることによって達成するものとしているので、注出操作が行い難いという問題がある。
【０００７】
摘み部分を単に長く設定し、外筒から大きく突出させて摘み易くすれば問題が解決するという提案もあるが、それでは容器全体の長さを無用に大きくするだけであり、持ち運びに便利なようにコンパクト化が要求されるこの種の容器としては賢明な解決策とはならない。
【０００８】
また、この従来技術にあっては、そのラチェット機構を、注出容器の軸心部に位置する雄螺子部とその外周に位置する軸受け筒に、爪片と係止凹部を設けることによってラチェット機構を構成するものとしているので、爪片および係止凹部ともに、その大きさが制限され、よってラチェット機構の機械的強度に問題が残ると共に、寸法上の厳しい規制のため当該ラチェット機構の成形がし難いものとなっている。
【０００９】
そこで、本発明は、上記した従来技術における問題点を解消すべく創案さたもので、容器の外形寸法を増大させることなく、操作のし易い摘み部分を形成し、また機械的に安定したラチェット機構を容易に構成することを技術的課題とし、もって円滑で良好な注出操作を得ると共に、機能が機械的に安定した容器を容易に成形することを目的とする。
【００１０】
【課題を解決するための手段】
上記技術的課題を解決する本発明の内、請求項１記載の発明の手段は、前端部に塗布部材を固定組付けし、略前半部分である太径部の後端から略後半部分である小径部を段差を介して一体連設し、この小径部の後端部に外方に突出する弾片状の爪片を設けた筒本体を有すること、この筒本体の小径部に回動自在に外装組付きすると共に、内周面後端部に、周方向に一定間隔で複数形成され、筒本体の爪片とでラチェット機構を構成する係止凹部を設けた有底筒状の外筒を有すること、筒本体の略後半部分に回動自在に内装組付きすると共に、後端部が外筒の後端部に固定組付きする棒螺子状の雄螺子部材を有すること、筒本体の略後半部分と雄螺子部材との間に摺接して嵌挿して、筒本体に回動不能かつ摺動自在に内装組付きし、雄螺子部材と螺合組付きする筒状の雌螺子部材を有すること、筒本体の太径部内に密に摺動自在に組付くと共に、雌螺子部材の先端部に固定組付きする中皿を有すること、中皿と塗布部材と筒本体とで形成される空間内に液状化粧料を収納する構成とすること、にある。
【００１１】
請求項２記載の発明は、請求項１記載の発明に、爪片を設けた筒本体の小径部の後端部に、割り溝状の一対の縦割り部を設けた、ことを加えたものである。
【００１２】
請求項３記載の発明は、請求項１記載の発明に、筒本体の小径部の後端部に、コの字状の切欠きを設けることにより、爪片を横向きの舌片状に設けた、ことを加えたものである。
【００１３】
請求項４記載の発明は、請求項３記載の発明に、縦割り部を、爪片を形成するコの字状の切欠きの縦部分に共用した、ことを加えたものである。
【００１４】
請求項５記載の発明は、請求項１記載の発明に、外筒の底壁上面に、中央に歯車状の係合軸を、そして係合軸から放射状に複数の係合片をそれぞれ突設し、雄螺子部材の後端部を筒状にして、後端開口部を係合軸が回動不能に嵌入係合する係合穴とすると共に、後端面に係合片が係合する複数の係合溝を設けた、ことを加えたものである。
【００１５】
【作用】
筒本体を固定した状態で外筒を回転させると、外筒の後端部に後端部が固定組付けされた雄螺子部材が一緒に回転し、これによって、雄螺子部材に螺合組付けされると共に筒本体に回動不能かつ摺動自在に内装組付けされた雌螺子部材が前進移動して、先端部に固定組付けした中皿を前方に押し出し、この中皿の前進移動によって、中皿と塗布部材と筒本体とで構成される空間内に収納されている液状化粧料を、塗布部材の先端部から押圧注出する。
【００１６】
筒本体の小径部の後端部に設けた爪片は、外筒の後端部に設けた係止凹部とでラチェット機構を構成しているので、雄螺子部材は筒本体に対して、液状化粧料を注出する方向にだけ回転し、逆方向には回転しないので、液状化粧料を押圧注出させながら前進した中皿が後退変位することはなく、このため中皿は常にに液状化粧料を注出できる位置に保持されていることになる。
【００１７】
筒本体の爪片と組合さってラチェット機構を構成する外筒の係止凹部は複数設けられており、爪片が係合凹部を乗り越える度に、回動抵抗が急激に増大するので、外筒の回転操作は、自然と一定回転量の間歇回転となり、このため液状化粧料の定量注出が容易となる。
【００１８】
筒本体を固定しての外筒の回転操作は、外筒が筒本体の後半部分である小径部に外装組付けされていることから、きわめて行い易いものとなる。
【００１９】
雌螺子部材を、内周面に螺条を刻設した単純な細長筒状としたので、雄螺子部材と雌螺子部材との組合せ物の外径を小さくすることが可能となり、これにより筒本体の小径部の径寸法を充分に小さく設定することができ、容器の外径寸法を増大させることなく、外筒の外嵌組付けを可能としている。
【００２０】
ラチェット機構を、最も径寸法の大きな外筒と、この外筒を外装組付けした筒本体の小径部との間に形成したので、ラチェット機構の構成部分に対する寸法上の規制が大幅に緩和され、これによりラチェット機構の成形が容易となると共に機械的な安定度を高めることができ、また操作力の作用部分である外筒を一方の機能部分としているので、ラチェット機構で発生する抵抗力が、各部分の組付きを劣化させる方向に作用することがなく、各構成部分の組付き状態を強固に安定して維持できる。
【００２１】
請求項２において、筒本体の小径部の後半部に一対の縦割り部を設けたので、この小径部の後半部の拡径方向への弾性変形がし易くなり、これにより小径部に対する雄螺子部材の挿入組付けが容易となる。
【００２２】
請求項３において、コの字状の切欠きを設けることにより、爪片を横向きの舌片状に設けたので、爪片に充分な弾性を付与することができ、これにより機械的に安定したラチェット機能を発揮すると共に、外筒のスムーズな回転操作を得ることができ、さらに爪片の係合凹部乗り越え時の衝撃を、確かな触感として感得することができる。
【００２３】
請求項４において、同じ切欠き構造部分である縦割り部とコの字状の切欠きとを、縦割り部をコの字状の切欠きの縦部分に共用したので、筒本体の小径部に成形される切欠き構造部分を少なくすることができ、これにより切欠き構造部分を成形することによる小径部の機械的強度の低下を最小限度に抑えることができると共に、小径部の構造の複雑化を抑えることができる。
【００２４】
請求項５において、外筒に対する雄螺子部材の不動な組付きを、係合軸と係合穴との嵌入係合だけではなく、放射方向に延びる係合片と係合溝との係合により達成しているので、略その径範囲の全域で組付きを達成維持することになり、これにより組付き力が中央部だけに集中することがなく、周囲部分にも分散するので、外筒と雄螺子部材との組付きを強力で安定したものとする。
【００２５】
【実施例】
本発明の一実施例を、図１〜図５に示す。
この実施例は、液状の口紅を収納する合成樹脂製の液状化粧料注出容器で、筒本体１、外筒２、雄螺子部材３、雌螺子部材４および中皿５を主な部材として構成している。
【００２６】
筒本体１は、前端部に塗布部材６を固定組付けし、ほぼその前半部分である太径の太径部７の後端から、ほぼその後半部分である小径の小径部８を、段差を介して一体的に連設した長筒状であり、そして小径部８のほぼ後半部分に軸方向に沿って一対の縦割り部１１を形成し、この縦割り部１１により二分された小径部８のそれぞれに、コの字状の切欠きを設けることにより、先端を外方に突出させた横向きの舌片状の爪片１０を設けている。
【００２７】
塗布部材６は、その中心部に液状化粧料２５が通過する通路２３を有すると共に、その先端部に通路２３を通過した液状化粧料２５が滲み出るようにして注出される部分で、かつ唇に直接接触する部分である塗布片２２を有する。
【００２８】
外筒２は、筒本体１の小径部８に回動自在に外装組付きする有底筒状であり、その外径は筒本体１の太径部７と同一に設定しており、これによって太径部７と外筒２との境界部分に段差が形成されることなく、滑らかに連続する外表面を形成し、またその内周面の後半部には、筒本体１の爪片１０とでラチェット機構を構成する複数（図４図示実施例では、六個）の係合凹部９が、周方向に沿って等間隔に設けられている。
【００２９】
また、この外筒２が小径部８に外装組付きすることによって、一対の縦割り部１１を設けることにより拡径方向に弾性変形し易くなり、雄螺子部材３の挿入組付けを容易に達成できるようにしている小径部８の後半部の拡径方向への変形を強制的に阻止し、これにより小径部８の後半部と雄螺子部材３の下端部との組付き状態を安定して維持する。
【００３０】
さらに、この外筒２の底壁の中心部から、雄螺子部材３の後端部に嵌入して固定組付きする歯車状の係合軸１５を突設すると共に、その中心部から径方向に、同じく雄螺子部材３の後端面に係合する四つの係合片１６を等中心角毎に突条設している。
【００３１】
係止凹部９と爪片１０とで構成されるラチェット機構（図４および図６参照）は、爪片１０が係合凹部９に係合した状態で、乗越え部１２の時計回り側端部である係止部１３に突き当たって乗り越え不能となるので、筒本体１に対して外筒２は逆方向に回転することができないことになる。
【００３２】
ラチェット機構は、図４に示した構造に限定されることはなく、例えば、図６に示すように、爪片１０を形成するコの字状の切欠きの縦部分を縦割り部１１と共用させた構造としても良く、この場合には、小径部８の後半部に形成される切欠きが少なくなるので、切欠きを設けることによる小径部８の機械的強度の低下を小さくすることができると共に、小径部８の後半部の構造の簡略化を得ることができる。
【００３３】
雄螺子部材３は、筒本体１内のほぼ後半部分に、小径部８より僅かに長い範囲にわたって回動自在に内装組付けされると共に、外筒２の後端部に、その後端部が固定組付けされており、外筒２との固定組付けは、筒状に成形された後端部の後端開口部に形成した歯車状の係合穴１７に外筒２の係合軸１５を係合させた状態で嵌入組付けし、さらに外鍔を一体設して幅広に構成した後端面に放射状に複数（図５図示実施例の場合、八個）の係合溝１８を形成し、この係合溝１８に外筒２の係合片１６を係合させることによって達成している。
【００３４】
雌螺子部材４は、内周面に螺条を刻設した単純な細長円筒形状をしていて、この雌螺子部材４と筒本体１との回動不能かつ摺動自在な組付き（図３参照）は、雌螺子部材４の外周面に軸方向に沿って刻設された一対の縦長溝１９に対する、筒本体１の小径部８内周面に軸方向に沿って突条設された一対の縦長片１４の係合により達成している。
【００３５】
中皿５は、高いシール性を発揮する軟質材料により一体成形されており、隔壁で上下に区画された前部筒２０と後部筒２１とから構成されていて、筒本体１の太径部７内に密に摺動自在に組付き、その後部筒２１が雌螺子部材４の先端部に強固に嵌合組付きする。
【００３６】
なお、この前部筒２０、筒本体１の太径部７、および塗布部材６との間に形成される空間に、液状化粧料２５を収納するものとしており、また塗布部材６を保護する等の目的で、当該塗布部材６を覆う形態のキャップ２４を設けている。
【００３７】
【発明の効果】
本発明は、上記した構成となっているので、以下に示す効果を奏する。
筒本体のほぼ後半部分を構成する小径部という長い範囲にわたって外筒を外装組付けし、この長くて掴み易い外筒を摘み部として回転させることによって液状化粧料を注出させるので、注出操作を容易に行うことができる。
【００３８】
雌螺子部材を、内周面に螺条を刻設した単純な細長円筒形状としたので、この雌螺子部材と雄螺子部材との組合せ物の外径を充分に小さくすることができ、これにより筒本体の小径部の外径を、容器全体の外径を増大させることなく、外筒を外嵌組付けすることができる程度の値に小さくすることができ、もって容器の外径寸法を増大させることなく、容器外面に好適な注出操作機能部分を形成する外筒を位置させることができる。
【００３９】
ラチェット機構を、径寸法の大きな外筒と筒本体の小径部との間に形成したので、比較的余裕のある成形スペースを得ることができ、これにより成形上の寸法規制の緩和を得ることができると共に、機械的に充分な強度に設計することができ、もってその成形が容易であると共に、安定したかつ円滑なラチェット機能を得ることができる。
【００４０】
請求項２記載の発明にあっては、筒本体の小径部に対する雄螺子部材の挿入組付けを安全で簡単なものとすることができ、もって容器全体の組立て作業の容易化を得ることができる。
【００４１】
請求項３記載の発明にあっては、ラチェット機構を構成する爪片に好適な弾力を確実にかつ安全に付与することができ、これにより円滑で確実なラチェット機能を得ることができ、もって円滑な注出操作を得ることができる。
【００４２】
請求項４記載の発明にあっては、筒本体の小径部に成形される切欠きを少なくすることができるので、切欠きを設けることによる小径部の機械的強度の低下を抑えることができ、もって小径部に大きな機械的強度の低下を引き起こすことなく、円滑なラチェット機能を得ることができる。
【００４３】
請求項５記載の発明にあっては、外筒と雄螺子部材との不動な結合を、中心部分だけではなく、径範囲の略全域で達成するので、外筒と雄螺子部材との強固で安定した結合を達成維持することができ、もって安定した液状化粧料の注出動作を得ることができる。

The engagement groove is provided.
[0015]
[Action]
When the outer cylinder is rotated while the cylinder body is fixed, the male screw member whose rear end is fixedly assembled to the rear end of the outer cylinder rotates together, thereby screwing and assembling to the male screw member. In addition, the female screw member that is internally mounted so as to be unrotatable and slidable on the cylinder body moves forward, pushes out the intermediate plate fixedly assembled to the tip, and forward movement of this intermediate plate, The liquid cosmetic contained in the space formed by the inner dish, the application member, and the cylinder body is pressed out from the tip of the application member.
[0016]
The claw piece provided at the rear end portion of the small-diameter portion of the cylinder main body constitutes a ratchet mechanism with the locking recess provided at the rear end portion of the outer cylinder, so that the male screw member is liquid with respect to the cylinder main body. Since it rotates only in the direction of dispensing cosmetics and does not rotate in the opposite direction, the inner plate that has advanced while the liquid cosmetic is pressed and dispensed does not move backward, so the inner plate is always in liquid makeup. It will be held in a position where it can be dispensed.
[0017]
There are multiple locking recesses on the outer cylinder that form a ratchet mechanism in combination with the claw piece of the cylinder body, and the rotation resistance increases rapidly each time the claw piece gets over the engagement recess. The rotation operation is a natural and intermittent rotation, which facilitates the quantitative dispensing of the liquid cosmetic.
[0018]
The rotating operation of the outer cylinder with the cylinder body fixed is extremely easy because the outer cylinder is externally assembled to the small-diameter portion that is the latter half of the cylinder body.
[0019]
Since the female screw member has a simple elongated cylindrical shape in which a thread is engraved on the inner peripheral surface, it becomes possible to reduce the outer diameter of the combination of the male screw member and the female screw member. The diameter of the small-diameter portion can be set sufficiently small, and the outer cylinder can be externally assembled without increasing the outer diameter of the container.

[0021]
In Claim 2, since a pair of vertically split portions are provided in the rear half of the small diameter portion of the cylinder body, the latter half of the small diameter portion is easily elastically deformed in the diameter increasing direction, thereby the male screw for the small diameter portion. The members can be easily inserted and assembled.
[0022]
In claim 3, by providing a U-shaped notch, the claw piece is provided in the shape of a lateral tongue piece, so that sufficient elasticity can be imparted to the claw piece, thereby making it mechanically stable. While exhibiting the ratchet function, it is possible to obtain a smooth rotation operation of the outer cylinder, and it is possible to feel the impact when the claw piece gets over the engaging recess as a reliable tactile sensation.
[0023]
In Claim 4, since the vertically-divided portion and the U-shaped notch that are the same notch structure portion are shared by the vertically-divided portion of the U-shaped notch, the small-diameter portion of the cylinder body It is possible to reduce the number of notch structure parts formed in the mold, thereby minimizing the decrease in mechanical strength of the small diameter part due to molding of the notch structure part, and the complexity of the structure of the small diameter part. Can be suppressed.
[0024]
6. The fixed assembly of the male screw member to the outer cylinder according to claim 5, in addition to the engagement engagement between the engagement shaft and the engagement hole, and the engagement between the engagement piece extending in the radial direction and the engagement groove.
