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】
【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。
【０００６】
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。
【０００７】
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れたもので、容器の外形寸法を増大させることなく、摘み機能部分を操作し易い大きさおよび配置とすることを技術的課題とし、もって液状内容液の円滑で正確な注出を達成すると共に、外観体裁の良い容器を得ることを目的とする。
【０００８】
【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内面に、周方向に一定間隔で複数の係止凹部を形成した長筒状の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、外筒の後端部に固定組付きする後端部分に、筒本体の係止凹部とでラチェット機構を構成する爪片を有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。
【０００９】
請求項２記載の発明は、請求項１記載の発明に、内面に係合凹部を形成した筒本体の小径部の後半分に、係合凹部としても機能する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。
【００１０】
請求項３記載の発明は、請求項１記載の発明に、雄螺子部材の爪片を設けた後端部を筒状とし、こ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形成した、ことを加えたものである。
【００１１】
請求項４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。
【００１２】
【作用】
筒本体を固定した状態で、この筒本体の後半部分に位置している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。
【００１３】
雄螺子部材の爪片は、筒本体の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。
【００１４】
雄螺子部材の爪片と組合さってラチェット機構を構成する筒本体の係止凹部は複数設けられており、爪片が係止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。
【００１５】
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可能となり、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。
【００１６】
請求項２において、筒本体の小径部の後半分に一対の縦割り部を設けたので、この小径部の後半分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り、また縦割り部の凹部構造をそのまま係合凹部として機能させることができるので、係合凹部を形成する小径部内周面部分の構造の簡略化に役立つ。
【００１７】
請求項３において、雄螺子部材の後端部を筒状とし、この筒状部にコの字状の切欠きを設けて横向きの舌片状の弾片を形成し、この弾片を爪片としたので、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、外筒の円滑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。
【００１８】
請求項４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。
【００１９】
【実施例】
本発明の一実施例を、図１〜図４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。
【００２０】
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間のそれぞれに等間隔に二つの係止凹部９を設け、一対の縦割り部１１を係止凹部９として機能させることにより、六つの係止凹部９機能部分を形成している。
【００２１】
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。
【００２２】
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することができている。
【００２３】
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し、これにより雄螺子部材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の後半部分の拡径方向への変形を強制的に阻止し、この縦割り部１１を安定して係止凹部９として機能することができるようにしている。
【００２４】
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係合片１６を等間隔で四本設けている。
【００２５】
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いて、外筒２との固定組付けは、爪片１０を設けた後半部を筒状に構成し、この筒状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を係合することによって達成している。
【００２６】
この雄螺子部材３の筒状となった後半部には、コの字状の切欠きを設けることにより横向き舌片状の一対の爪片１０が設けられており、筒本体１の係止凹部９とでラチェット機構を構成し、雄螺子部材３を時計回り方向へ回転させると一対の爪片１０が、その自由端を内方に弾性変位させて乗越え部１２を乗り越えて次の係止凹部９に侵入係止位置する。
【００２７】
なお、雄螺子部材３を逆方向に回転しようとしても、乗越え部１２の時計回り側部分が、爪片１０の乗り越えが不可能な係止部１３となっているので、この係止部１３に対する爪片１０の突き当たりにより、雄螺子部材３の逆方向への回転は不能となる。
【００２８】
雌螺子部材４は、内周面に螺条を刻設した単純な細長筒状をしていて、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。
【００２９】
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。
【００３０】
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。
【００３１】
【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、その長くて掴み易い外筒を回転させることによって液状化粧料を注出させることとしているので、注出操作を円滑にかつ容易に行うことができる。
【００３２】
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、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、もって容器の外径を増大させることなく、容器外面に注出操作機能部分である外筒を位置させることができる。
【００３３】
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ると共に、複雑となり勝ちなラチェット機構の構造を簡単化させることができる。
【００３４】
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、もって液状化粧料の円滑な注出動作を得ることができる。
【００３５】
請求項４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。

[0007]
Therefore, the present invention was devised to solve the above-mentioned problems in the prior art, and it is technically intended to make the size and position of the knob function portion easy to operate without increasing the outer dimensions of the container. An object is to achieve a smooth and accurate dispensing of the liquid content liquid and to obtain a container having a good appearance.
[0008]
[Means for Solving the Problems]
Among the present invention for solving the above technical problems, the means of the invention according to claim 1 is that the applicator member is fixedly assembled to the front end portion, and is from the rear end of the large-diameter portion which is the substantially first half portion to the substantially second half portion. A small-diameter portion is integrally connected via a step, and an inner surface of the rear-end portion of the small-diameter portion has an elongated cylindrical main body formed with a plurality of locking recesses at regular intervals in the circumferential direction. Having a bottomed cylindrical outer cylinder that is rotatably attached to the small-diameter portion, and is rotatably attached to the inner half of the cylinder main body and fixedly attached to the rear end of the outer cylinder. It has a rod screw-like male screw member having a claw piece that constitutes a ratchet mechanism at the rear end portion with a locking recess of the tube main body, and is in sliding contact between the substantially latter half portion of the tube main body and the male screw member. It has a cylindrical female screw member that is inserted and attached to the cylinder body so that it cannot rotate and is slidable, and is screwed into the male screw member. Rukoto, the grapple freely tightly slidable within the large-diameter portion of the tube body, to have the inner plate that with fixed set on the tip portion of the female screw member, formed by the inner plate and the coating member and the cylindrical body The present invention is configured to store the liquid cosmetic in the space .
[0009]
A second aspect of the invention is the same as that of the first aspect of the invention, wherein the rear half of the small-diameter portion of the cylinder body having an engagement recess formed on the inner surface has a pair of split groove-like vertical split portions that also function as the engagement recess. Is added to that.
[0010]

The rear end portion of the male screw member is formed into a cylindrical shape, and the rear end opening is formed as an engagement hole into which the engagement shaft is non-rotatably fitted and engaged, and a plurality of engagement pieces are engaged with the rear end surface. The engagement groove is provided.
[0012]
[Action]
When the outer cylinder located in the second half of the cylinder body is rotated with the cylinder body fixed, the male screw member with the rear end fixedly assembled to the rear end of the outer cylinder rotates together. As a result, the female screw member that is screwed and assembled to the male screw member and that is internally mounted in the cylinder main body so as not to be rotatable and slidable moves forward, and the inner plate fixedly assembled to the tip portion is moved. The liquid cosmetics stored in the space formed by the inner plate, the application member, and the cylinder main body are pressed out from the tip of the application member by pushing forward and moving the inner plate forward.
[0013]
Since the claw piece of the male screw member constitutes a ratchet mechanism with the locking recess of the cylinder body, the male screw member rotates only in the direction in which the liquid cosmetic is poured with respect to the cylinder body, and in the reverse direction. Therefore, the intermediate dish that has been moved forward while the liquid cosmetic is pressed and dispensed does not move backward, so that the intermediate dish is always held at a position where the liquid cosmetic can be dispensed.

The members can be easily inserted and assembled, and the concave structure of the vertically split portion can be used as it is as an engaging concave portion, which is useful for simplifying the structure of the inner peripheral surface portion of the small diameter portion forming the engaging concave portion.
[0017]
4. The rear end portion of the male screw member is formed into a cylindrical shape, and a U-shaped notch is provided in the cylindrical portion to form a lateral tongue-shaped bullet piece. As a result, sufficient elasticity can be imparted to the claw piece, thereby exhibiting a mechanically stable ratchet function, smooth rotation operation of the outer cylinder, and further engagement of the claw piece The impact when getting over the recess can be felt as a reliable tactile sensation.
[0018]
5. The fixed assembly of the male screw member to the outer cylinder according to claim 4, not only by fitting engagement between the engagement shaft and the engagement hole, but also by engagement between the engagement piece extending in the radial direction and the engagement groove. Since it has been achieved, assembly will be achieved and maintained in almost the entire diameter range, so that the assembly force will not be concentrated only in the central part, but will also be dispersed in the surrounding part. Assume that the assembly with the male screw member is strong and stable.
