Description

本願発明は、例えばアイブロー、アイライナー、アイシャドー又はリップライナー等の細径化され、且つ非常に柔軟な棒状化粧料を出没自在に収容してなる棒状化粧料容器に関するものである。 The present invention relates to a bar-shaped cosmetic container that is made of a thin and extremely flexible bar-shaped cosmetic such as an eyebrow, eyeliner, eye shadow, or lip liner, and that can be retracted and retracted.

従来より、例えば上記各種棒状化粧料を出没自在に軸筒内に収容してなる棒状化粧料容器は、棒状化粧料を固持する昇降筒をネジ機構を利用して軸筒内で昇降させることによって、該昇降筒に固持される棒状化粧料を軸筒内外に出没させるものが一般的である。 Conventionally, for example, a bar-shaped cosmetic container in which the various bar-shaped cosmetics are housed in a shaft cylinder so as to be able to appear and retract is obtained by moving a lifting cylinder holding the bar-shaped cosmetic material up and down in the shaft cylinder using a screw mechanism. In general, the bar-shaped cosmetics fixed to the elevating cylinder are made to appear and disappear in and out of the shaft cylinder.

しかしながら、リップライナー等の棒状化粧料は、細部まで正確に塗布可能なように細径化されており、近年流行の艶のあるリップグロスに合わせて化粧料が処方されているので、棒状の化粧料自体が非常に柔軟なものとなっている。そのため、該棒状化粧料容器の製造にあたっては、芯チャックを内装した棒状化粧料収容体に溶融した化粧料を直接充填して固化させている。従って、一旦棒状化粧料収容体より突出させた棒状化粧料を再度棒状化粧料収容体内に没入させようとすると、その柔軟さ故に該棒状化粧料が棒状化粧料収容体の内壁面と擦れて破断等を起こすおそれがある。すなわち、このような棒状化粧料では、一旦棒状化粧料収容体から棒状化粧料を突出させた後は、該棒状化粧料を棒状化粧料収容体内に没入させることを予定しておらず、使用後はそのままキャップを装着するものとしている。ところが、棒状化粧料収容体の先端より棒状化粧料を突出させたままの状態であると、その突出長によっては、キャップを装着した際にキャップの内側がその突出した棒状化粧料の先端に当接して、キャップを確実に装着することができず、また無理矢理キャップを装着してしまうと該棒状化粧料の先端がキャップにより潰れてしまうことで、キャップが固着し、また棒状化粧料が漏出して他所を汚損するおそれがある。 However, stick-shaped cosmetics such as lip liners have been reduced in diameter so that they can be applied precisely to the details, and cosmetics are formulated according to the glossy lip gloss that has become popular in recent years. The fee itself is very flexible. For this reason, when manufacturing the bar-shaped cosmetic container, the melted cosmetic is directly filled and solidified in a bar-shaped cosmetic container with a core chuck. Therefore, when the bar-shaped cosmetic once protruded from the bar-shaped cosmetic container is intended to be immersed again in the bar-shaped cosmetic container, the bar-shaped cosmetic rubs against the inner wall surface of the bar-shaped cosmetic container and breaks due to its flexibility. There is a risk of causing this. That is, in such a bar-shaped cosmetic, once the bar-shaped cosmetic is protruded from the bar-shaped cosmetic container, it is not planned to be immersed in the bar-shaped cosmetic container, and after use Is supposed to wear a cap as it is. However, if the stick-shaped cosmetic is left protruding from the tip of the stick-shaped cosmetic container, depending on the protruding length, the inner side of the cap may contact the tip of the protruding stick-shaped cosmetic when the cap is attached. The cap cannot be securely attached, and if the cap is forcibly attached, the tip of the bar-shaped cosmetic material is crushed by the cap, so that the cap is fixed and the bar-shaped cosmetic material leaks out. May contaminate other places.

更に、棒状化粧料容器は通常小さな鞄に入れて持ち運ぶので、その全長は短いほど有利であるが、使用時おいて棒状化粧料容器の全長があまりに短いと指により確実に保持できず、正確な塗布作業を行えないものである。
特開平８−３５３号 Furthermore, since the stick-shaped cosmetic container is usually carried in a small bag, it is advantageous that its overall length is short. However, if the full length of the stick-shaped cosmetic container is too short in use, it cannot be held securely with fingers, and accurate. Application work cannot be performed.
JP-A-8-353

解決しようとする問題点は、非常に柔軟な棒状化粧料を保持した棒状化粧料容器においても、非使用時においてはキャップを確実に装着することができるようにするとともに、その容器自体の全長を短縮化する一方、使用時においてはその全長を適正な長さとして、棒状化粧料の正確な塗布作業ができるようにするものである。 The problem to be solved is that even in a stick-shaped cosmetic container holding a very flexible stick-shaped cosmetic, the cap can be securely attached when not in use, and the total length of the container itself is reduced. On the other hand, when used, the entire length is set to an appropriate length so that the bar-shaped cosmetic can be accurately applied.

そのために、棒状化粧料容器は、棒状化粧料を突出可能に保持する棒状化粧料収容体自体を出没自在とするとともに、更に該棒状化粧料収容体に保持される棒状化粧料を突出可能にしてなるものである。 For this purpose, the stick-shaped cosmetic container allows the stick-shaped cosmetic container itself that can hold the stick-shaped cosmetic so as to protrude, and allows the stick-shaped cosmetic held by the stick-shaped cosmetic container to protrude. It will be.

そこで、軸筒と先筒とからなる化粧料容器本体と、該先筒の開口部に対して脱着自在となるキャップから構成され、
該化粧料容器本体内には、棒状化粧料を突出可能に収容する棒状化粧料収容体、該棒状化粧料収容体を先筒の開口部より出没自在とする収容体出没機構、及び棒状化粧料を前記棒状化粧料収容体より突出させてなる棒状化粧料突出機構を内装し、
該化粧料容器本体は、離脱不能であって且つ相互に回転可能となる回転嵌合部を持って一体となる先筒と軸筒からなり、該先筒の後端側内周面には前後方向に案内溝を溝設するものであり、
該棒状化粧料収容体は、筒状の芯筒と、該芯筒内で棒状化粧料を保持する芯チャックからなり、
収容体出没機構はネジ筒と回転筒と回止筒とからなり、該ネジ筒は内周面に螺旋状のネジ溝をネジ筒の先端縁に至らない範囲で刻設し、該回転筒は、前記ネジ溝に遊嵌する係合突起を外周に設けるとともに、該係合突起の前方には回止筒の後端縁を係止する鍔部を周設し、又、その内周面にはラチェット機構を構成する可動カムのローレットと噛合するローレットを設けてなり、該回止筒は、先筒の内周面に前後方向に溝設する案内溝に遊嵌、案内される係止突起を外周面に突設するものであって、前記回転筒と回止筒とは離脱不能且つ相互に個別回転可能に結合され、
該棒状化粧料突出機構は、ネジ軸とラチェット機構とスリーブとからなり、該ネジ軸はその外周面に雄ネジ部を螺設してなり、該ラチェット機構は固定カムと可動カム及び回転筒内において可動カムを固定カム側へ押勢するスプリングとからなって、可動カムの回転方向を、収容体出没機構によって棒状化粧料収容体を先筒の開口部より突出させるために必要となる軸筒の回転方向のみに規制し、該スリーブは、その内周面に前記ネジ軸の外周面に螺設された雄ネジ部に螺合する雌ネジ部を配設してなり、
軸筒と離脱不能且つ相互に個別回転不能に結合されたネジ筒のネジ溝に回転筒の係合突起を遊嵌して一体とした上で、該回転筒とネジ軸とを離脱不能且つ相互に個別回転不能に結合するとともに、該回転筒の内部に設けたローレットに可動カムの外周に存するローレットを噛合させ、回転筒内に設けたスプリングの弾撥力によって、回止筒と係合して回転不能である固定カムに対して可動カムを、棒状化粧料収容体を先筒の開口部より突出させるために必要となる軸筒の回転方向と同方向へのみ回転可能に規制し、又、該回転筒と離脱不能且つ相互に個別回転可能に結合された回止筒は、その前方側において前記芯筒の後端側と離脱不能且つ相互に個別回転不能に結合され、更に、スリーブの先端側においてスリーブと芯チャックとを離脱不能且つ相互に個別回転不能となるよう一体とすることにより、軸筒の回転によるネジ筒の回転によって回転筒を軸筒内において前後方向に摺動可能とし、当該回転筒の摺動によって棒状化粧料収容体を先筒の開口部より出没自在とするとともに、該棒状化粧料収容体が先筒の開口部より突出した状態で更に同方向へ軸筒を回転させることによって、回転筒の回転によるネジ軸の回転によってスリーブを前方へ摺動させて、該スリーブと一体となる芯チャックの前進によって棒状化粧料を芯筒より突出させてなるものである。Therefore, it is composed of a cosmetic container body composed of a shaft tube and a tip tube, and a cap that is detachable with respect to the opening of the tip tube,
In the cosmetic container main body, a rod-shaped cosmetic container that accommodates the rod-shaped cosmetic so as to protrude, a container body retracting mechanism that allows the rod-shaped cosmetic container to protrude and retract from the opening of the front tube, and the rod-shaped cosmetic A stick-shaped cosmetic protrusion mechanism that protrudes from the stick-shaped cosmetic container,
The cosmetic container body is composed of a front tube and a shaft tube that are integral with a rotation fitting portion that cannot be detached and can rotate with respect to each other. Guide grooves in the direction,
The rod-shaped cosmetic container comprises a cylindrical core tube and a core chuck for holding the rod-shaped cosmetic material in the core tube,
The container retracting mechanism is composed of a screw cylinder, a rotating cylinder, and a rotation cylinder, and the screw cylinder is provided with a spiral thread groove on the inner peripheral surface within a range not reaching the tip edge of the screw cylinder. In addition, an engagement protrusion that loosely fits in the screw groove is provided on the outer periphery, and a collar portion that locks the rear end edge of the stop cylinder is provided in front of the engagement protrusion, and an inner peripheral surface thereof is provided. Is provided with a knurling that meshes with the knurling of the movable cam constituting the ratchet mechanism, and the locking cylinder is loosely fitted and guided in a guide groove provided in the front-rear direction on the inner peripheral surface of the front cylinder. Projecting on the outer peripheral surface, and the rotating cylinder and the non-rotating cylinder are coupled to each other so that they cannot be detached and can be individually rotated.
The bar-shaped cosmetic material protruding mechanism includes a screw shaft, a ratchet mechanism, and a sleeve, and the screw shaft has a male thread portion screwed on an outer peripheral surface thereof. The ratchet mechanism includes a fixed cam, a movable cam, and a rotating cylinder. And a spring that urges the movable cam toward the fixed cam side, and the shaft cylinder that is necessary for projecting the bar-shaped cosmetic container from the opening of the front cylinder by the container retracting mechanism in the rotating direction of the movable cam The sleeve is provided with a female screw portion that is threadedly engaged with a male screw portion that is screwed on the outer peripheral surface of the screw shaft, on the inner peripheral surface of the sleeve,
An engaging projection of a rotating cylinder is loosely fitted into a thread groove of a screw cylinder that is coupled to the shaft cylinder so that it cannot be separated and cannot be individually rotated, and then the rotating cylinder and the screw shaft cannot be separated from each other. The knurls provided on the outer periphery of the movable cam are meshed with the knurls provided inside the rotary cylinder, and are engaged with the stop cylinder by the elastic force of the spring provided in the rotary cylinder. The movable cam is restricted so as to be rotatable only in the same direction as the rotation direction of the shaft cylinder, which is necessary for the stick-shaped cosmetic container to protrude from the opening of the front cylinder. The rotating cylinder coupled to the rotating cylinder so as not to be separated and capable of being individually rotated is coupled to the rear end side of the core cylinder on the front side thereof so as not to be separated from each other and so as not to be individually rotatable. The sleeve and core chuck cannot be detached on the tip side. In addition, by making them integral with each other so that they cannot be individually rotated, the rotating cylinder can be slid back and forth in the axial cylinder by the rotation of the screw cylinder by the rotation of the axial cylinder. By making the container freely projecting and retracting from the opening of the front tube, and rotating the shaft tube in the same direction with the stick-shaped cosmetic container projecting from the opening of the front tube, the screw by rotation of the rotating tube The sleeve is slid forward by the rotation of the shaft, and the bar-shaped cosmetic is protruded from the core cylinder by the advancement of the core chuck integrated with the sleeve.

そのため、使用に際しては、先筒を持って軸筒を回転させると、該軸筒とその内部で一体に共回りするネジ筒の回転により回転筒が化粧料容器本体内を前進するので、先筒の内周面の案内溝に係止突起を遊嵌するとともに、回転筒と離脱不能に結合された回止筒、及び該回止筒と離脱不能に結合された芯筒が前進することとなる。又、同時に回転筒と離脱不能に結合されたネジ軸も前進し、該ネジ軸と螺合して一体となるスリーブ並びに、該スリーブと一体となる芯チャックもそれぞれ同時に前進することとなる。その結果、棒状化粧料収容体全体が同方向へ前進することから、先軸の開口部より棒状化粧料収容体が突出する。そして、該回転筒の係合突起がネジ筒のネジ溝先端に至ると、軸筒と回転筒とは共回りすることとなるが、その際、回転筒と一体となる回止筒は先筒の案内溝に遊嵌していることから回転せず、回転筒のみが回転することとなる。そこで、更に軸筒を回転させると、該回転筒の回転はネジ軸に伝達される。即ち、ネジ軸と回転軸とは一体に共回りするものである。従って、ネジ軸が回転することで、該ネジ軸の外周面に螺設される雄ネジ部と螺合する雌ネジ部をその内周面に配設するスリーブは前進する。その結果、スリーブと一体となっている芯筒内の芯チャックが前進し、棒状化粧料は芯筒の開口部より突出するものとなる。 Therefore, in use, when the shaft cylinder is rotated by holding the tip cylinder, the rotating cylinder advances in the cosmetic container body by the rotation of the screw cylinder that rotates integrally with the shaft cylinder and the inside thereof. The locking projection is loosely fitted in the guide groove on the inner peripheral surface of the inner cylinder, the rotation cylinder coupled to the rotation cylinder so as not to be detached, and the core cylinder coupled to the rotation cylinder so as not to be separated move forward. . At the same time, the screw shaft, which is coupled to the rotating cylinder so as not to be detached, advances, and the sleeve integrated with the screw shaft and the core chuck integrated with the sleeve also advance simultaneously. As a result, since the whole stick-shaped cosmetic container advances in the same direction, the stick-shaped cosmetic container projects from the opening of the front shaft. When the engaging projection of the rotating cylinder reaches the tip of the thread groove of the screw cylinder, the shaft cylinder and the rotating cylinder rotate together. At this time, the rotating cylinder integrated with the rotating cylinder is the leading cylinder. Since it is loosely fitted in the guide groove, only the rotating cylinder rotates without rotating. Therefore, when the shaft cylinder is further rotated, the rotation of the rotating cylinder is transmitted to the screw shaft. That is, the screw shaft and the rotating shaft rotate together. Accordingly, when the screw shaft is rotated, the sleeve in which the female screw portion screwed with the male screw portion screwed on the outer peripheral surface of the screw shaft is moved forward is advanced. As a result, the core chuck in the core cylinder integrated with the sleeve advances, and the bar-shaped cosmetic protrudes from the opening of the core cylinder.

また、使用後は、軸筒を逆回転させることで回転筒はネジ筒のネジ溝に沿って後退するものとなり、該回転筒と離脱不能に結合する回止筒、更に該回止筒と離脱不能に結合する棒状化粧料収容体の芯筒、並びに該回転筒と離脱不能に結合しているネジ軸、更には棒状化粧料収容体の芯チャックと一体となり、該ネジ軸と螺合して一体となるスリーブもそれぞれ後退することとなるので、棒状化粧料収容体は化粧料容器本体内に没入するものとなる。なお、回転筒とネジ軸との間にはネジ軸の回転を一方向にのみ許容するラチェット機構が介在しているので、過剰に軸筒を逆回転させようとしてもネジ軸は回転することはないので、棒状化粧料を保持する芯チャックと一体となるスリーブは後退することはなく、棒状化粧料が芯チャックと共に芯筒内に後退することでの破損を防止できる。 In addition, after use, by rotating the shaft cylinder in the reverse direction, the rotating cylinder moves backward along the thread groove of the screw cylinder. A core cylinder of the rod-shaped cosmetic container that is impossiblely coupled, a screw shaft that is undetachably coupled to the rotating cylinder, and a core chuck of the rod-shaped cosmetic container, and are screwed into the screw shaft. Since the integral sleeves are also retracted, the stick-shaped cosmetic container is immersed in the cosmetic container body. Note that a ratchet mechanism that allows rotation of the screw shaft in only one direction is interposed between the rotating tube and the screw shaft, so that the screw shaft does not rotate even if the shaft tube is rotated in the reverse direction excessively. Therefore, the sleeve integrated with the core chuck holding the bar-shaped cosmetic material does not move backward, and damage due to the bar-shaped cosmetic material moving back together with the core chuck into the core cylinder can be prevented.

本願発明は、細径化され、且つ非常に柔軟な棒状化粧料を棒状化粧料容器より円滑に出没させるとともに、その塗布も確実に行うことができるという優れた効果を有する。 The invention of this application has an excellent effect that the diameter-reduced and very flexible bar-shaped cosmetic can be made to appear and disappear more smoothly than the bar-shaped cosmetic container, and the application can be performed reliably.

図１乃至図７に示す１は、本願発明の実施例における使い捨ての棒状化粧料容器である。該棒状化粧料容器１は、先筒４と該先筒４に対して回転自在に取り付けられる軸筒１３とからなる化粧料容器本体３と、該化粧料容器本体３の先筒４前端の開口部５に対して脱着自在となるキャップ２とから構成されるものである。（なお、本明細書においては、化粧料容器本体３の先筒４の開口部５方向を前もしくは先、軸筒１３の方向を後として方向を指示する。） Reference numeral 1 shown in FIGS. 1 to 7 denotes a disposable bar-shaped cosmetic container according to an embodiment of the present invention. The bar-shaped cosmetic container 1 includes a cosmetic container body 3 including a front tube 4 and a shaft tube 13 that is rotatably attached to the front tube 4, and an opening at the front end of the front tube 4 of the cosmetic container body 3. The cap 2 is detachable from the portion 5. (In this specification, the direction is indicated with the direction of the opening 5 of the front tube 4 of the cosmetic container body 3 as the front or front and the direction of the shaft tube 13 as the rear.)

該先筒４は、外周面に径外方向に突出する係止縁６を略中央に周設すると共に、その後端近傍外周には，軸筒１３（後述する。）の内周面略中央に配設する係止凸部１５と嵌合して、離脱不能であって且つ相互に回転可能となる回転嵌合部１００を形成する係止凹部７が周設され、さらに該先筒４の内周面には、回止筒３３（後述する。）の外周面に突設する係止突起３８を先筒４の前後方向に摺動自在に遊嵌してなる案内溝９が、後端縁８より前方に向かって溝設されている。また、該係止突起３８からそれぞれ９０度回転した位置に，摩擦弾性体１０が対向して配設されている。そして該摩擦弾性体１０は，軸筒１３側へ弾性をもって拡開するように形成される弾性片１１と，該弾性片１１の表面に，軸筒１３の内周面１４に当接するように一体に突設された摩擦突起１２からなるものである。そのため、先筒４の摩擦弾性体１０の摩擦突起１２が常時確実に軸筒１３の内周面１４に当接するので、軸筒１３を回転させると、軸筒１３の内周面１４と先筒４の摩擦弾性体１０の摩擦突起１２との間で摩擦が生じ、節度ある操作感が生まれるようになる。
一方、軸筒１３は、一端を封止した略円筒形状であって、その内周面１４略中央では、上述のように先筒４の外周面の係止凹部７と嵌合して、離脱不能であって且つ相互に回転可能となる回転嵌合部１００を形成する係止凸部１５が突設され、又，後述するように，その内底部近傍の内壁面には，内装するネジ筒１８（後述する。）の外周面の係止凹部２１と嵌合して、離脱不能であって且つ同期して回転する（すなわち相互に個別回転不能となる）固定嵌合部１０１を形成する係止凸部１６が形成されるとともに、ネジ筒１８のローレット２２と噛合して共回りしてなる固定噛合部１０２を形成するローレット１７が配設されているものである。
以上より、前記化粧料容器本体３をなす先筒４と軸筒１３とは、先筒４の外周面に周設される係止縁６を軸筒１３の前端縁に、先筒４の後端縁８を軸筒１３の内周面に周設した段部１４’にそれぞれ係止するとともに、先筒４の外周面の係止凹部７と軸筒１３の内周面１４の略中央の係止凸部１５とを嵌合させることで、離脱不能であって且つ相互に回転可能となる回転嵌合部１００を形成して一体となるものである。The front tube 4 is provided with a locking edge 6 projecting radially outward on the outer peripheral surface at a substantially central position, and at the outer periphery in the vicinity of the rear end thereof at a substantially central position on the inner peripheral surface of a shaft tube 13 (described later). A locking recess 7 is formed around the front tube 4 so as to be fitted with the locking protrusion 15 to be disposed and to form a rotation fitting portion 100 that cannot be detached and can rotate with each other. On the peripheral surface, there is a guide groove 9 formed by loosely fitting a locking projection 38 projecting on the outer peripheral surface of the stop cylinder 33 (described later) in the front-rear direction of the front cylinder 4. A groove is formed forward from 8. In addition, the friction elastic body 10 is disposed so as to face each other at a position rotated 90 degrees from the locking projection 38. The friction elastic body 10 is integrated with an elastic piece 11 formed so as to expand elastically toward the shaft tube 13 side, and an inner surface 14 of the shaft tube 13 on the surface of the elastic piece 11. It consists of the friction protrusion 12 protrudingly provided on the surface. Therefore, since the friction projection 12 of the friction elastic body 10 of the front tube 4 always reliably contacts the inner peripheral surface 14 of the shaft tube 13, when the shaft tube 13 is rotated, the inner peripheral surface 14 and the front tube of the shaft tube 13 are rotated. Friction is generated between the frictional elastic bodies 10 and the friction projections 12 of the frictional body 10, and a moderate operational feeling is born.
On the other hand, the shaft tube 13 has a substantially cylindrical shape with one end sealed. At the center of the inner peripheral surface 14, the shaft tube 13 is engaged with the engaging recess 7 on the outer peripheral surface of the front tube 4 as described above, and is detached. A locking projection 15 that forms a rotation fitting portion 100 that is impossible and can rotate with respect to each other protrudes from the inner wall surface in the vicinity of the inner bottom, as will be described later. 18 (described later) is engaged with a locking recess 21 on the outer peripheral surface to form a fixed fitting portion 101 that cannot be detached and rotates synchronously (that is, cannot be individually rotated). A stop ridge 16 is formed, and a knurl 17 is provided that forms a fixed engagement portion 102 that meshes with the knurl 22 of the screw cylinder 18 and rotates together.
As described above, the front tube 4 and the shaft tube 13 forming the cosmetic container body 3 are configured such that the locking edge 6 provided around the outer peripheral surface of the front tube 4 is the front end edge of the shaft tube 13 and the rear tube 4 The end edge 8 is engaged with a stepped portion 14 ′ provided around the inner peripheral surface of the shaft tube 13, and the engagement recess 7 on the outer peripheral surface of the front tube 4 and the substantially central portion of the inner peripheral surface 14 of the shaft tube 13. By fitting the locking projection 15, a rotation fitting portion 100 that cannot be detached and can rotate with each other is formed and integrated.

そして、上記先筒４と軸筒１３からなる化粧料容器本体３内には、棒状化粧料７５を突出可能に収容する棒状化粧料収容体６７を、軸筒１３の回転により先筒４の開口部５より出没させる収容体出没機構イ、及び軸筒１３の回転により棒状化粧料収容体６７内に収容される棒状化粧料７５を該棒状化粧料収容体６７の芯筒６８の開口部６８’より突出させてなる棒状化粧料突出機構ロを内装するものである。 And in the cosmetic container main body 3 which consists of the said front cylinder 4 and the axial cylinder 13, the rod-shaped cosmetics accommodating body 67 which accommodates the rod-shaped cosmetic 75 so that protrusion is possible is carried out, and the opening of the front cylinder 4 is carried out by rotation of the axial cylinder 13. An opening 68 ′ of a core cylinder 68 of the rod-shaped cosmetic container 67, which is caused to protrude and retract from the portion 5, and a rod-shaped cosmetic 75 accommodated in the rod-shaped cosmetic container 67 by the rotation of the shaft cylinder 13. A rod-shaped cosmetic material protruding mechanism B that is further protruded is provided.

上記収容体出没機構イは、軸筒１３内において、内周面にネジ溝１９を刻設するネジ筒１８と、該ネジ筒１８のネジ溝１９に係合する係合突起２５を対向するように後端に配置する回転筒２３と、外周面に先筒４の内周面の案内溝９に遊嵌する係止突起３８を突設する回止筒３３とからなるものである。 The housing projecting / retracting mechanism (a) is configured so that, in the shaft cylinder 13, the screw cylinder 18 that engraves the screw groove 19 on the inner peripheral surface thereof and the engagement protrusion 25 that engages with the screw groove 19 of the screw cylinder 18 face each other. The rotating cylinder 23 is arranged at the rear end, and the rotation cylinder 33 is provided with a locking projection 38 projectingly fitted in the guide groove 9 on the inner peripheral surface of the front cylinder 4 on the outer peripheral surface.

ここで該ネジ筒１８は、その内周面の対向する位置において２条の左螺旋状（後方側から見て）のネジ溝１９が刻設されている。そしてネジ溝１９の後端側はネジ筒１８の後端縁に達し、先端側はネジ筒１８の先端縁には達していないものの、各ネジ溝１９の後端と先端とは１８０度回転した位置に設けられる。その上、その先端側終端には、その螺旋の進行方向側に向かって円周方向に沿って切り欠き溝２０を溝設するものである。又、ネジ筒１８の外周面においては，軸筒１３の後端側の内周面１４に周設する係止凸部１６と嵌合して、離脱不能であって且つ同期して回転する（すなわち相互に個別回転不能）固定嵌合部１０１を形成してなる係止凹部２１と、軸筒１３の更に後端側の内周面１４に配設されるローレット１７と噛合して共回りする固定噛合部１０２を形成してなるローレット２２を，それぞれ配設してなるものである。
そして該回転筒２３は径小部２４と径大部２６とからなり、該径小部２４では、その後端縁にネジ筒１８の内周面に刻設されるネジ溝１９に係合する係合突起２５が対向するように配設される。また、該径大部２６では、その外周面後端において、径外方向に突出し、回止筒３３の後端縁３４を係止する鍔部２７を周設するとともに、回止筒３３の内周面と当接するＯリング２９を着装する係止溝２８を円周方向に溝設し、更に回止筒３３の後端近傍の内周面に設けられた係止凹部４０と嵌合して、離脱不能であって且つ相互に回転可能となる回転嵌合部１０３を形成する係止凸部３０を配設するものである。
また、径大部２６内部にはネジ軸４１（後述する。）の係止凸部４３と嵌合して、離脱不能であって且つ同期して回転する（すなわち相互に個別回転不能）固定嵌合部１０４を形成する係止凹部３１が配設されるとともに、該径大部２６の前端縁内周面にはラチェット機構４６（後述する。）を構成する可動カム４９の外周面に配設するローレット５０と噛合して一体に共回りする固定噛合部１０５を形成するローレット３２が配設されている。
そのため、該ネジ筒１８のネジ溝１９に係合する係合突起２５を有する回転筒２３は、軸筒１３を右回転させることによってネジ筒１８のネジ溝１９の傾斜面１９ａに案内されて前進する。そして、軸筒１３を約３分の２回転させると、回転筒２３の係合突起２５が該ネジ溝１９の先端に至ることから、それ以上の軸筒１３の回転によっても回転筒２３はそれ以上前進せず、逆に、ネジ溝１９に設けられた切り欠き溝２０に嵌合して固持されるものとなる。その結果、軸筒１３を更に回転させることで棒状化粧料突出機構ロを作動させることができる。また、先筒４の開口部５より突出している棒状化粧料収容体６７が先筒４内方向へ押勢されても、回転筒２３の係合突起２５とネジ溝１９の切り欠き溝２０とが嵌合しているので、回転筒２３の係合突起２５がネジ筒１８のネジ溝１９に沿って逆回転して先筒４内に没入することを防止できるものとなる（図６参照）。
その上、回止筒３３は、略円筒状であって、その後端縁３４は回転筒２３の鍔部２７に当接し、前端縁３５は芯筒６８の内周面に突設される係止周縁６９の後面に当接している。そして該回止筒３３は、その前端縁３５近傍の外周面において芯筒６８の内周面の係止凹部７１と嵌合して、離脱不能であって且つ同期して回転する（すなわち相互に個別回転不能）固定嵌合部１０６を形成する係止凸部３６及び、該芯筒６８の後端内周面に配設するローレット７０と噛合して一体に共回りする固定噛合部１０７を形成するローレット３７を配設するとともに、先筒４の内周面に軸方向に刻設される案内溝９に遊嵌する係止突起３８が突設されている。また回止筒３３の後端側内周面においては、後述するラチェット機構４６をなす固定カム４７の基部４７ａ側面に形成する凹凸部５１に係合して該固定カム４７を固持してなる凹凸部３９を配設するとともに、回転筒２３の径大部２６の外周面に突設する係止凸部３０と、離脱不能であって且つ相互に回転可能となる回転嵌合部１０３を形成する係止凹部４０を、更にその後端側に配設してなるものである。

以上のように、本願発明の実施例における棒状化粧料容器１は構成されるので、使用者は次のようにして上記棒状化粧料容器１を使用に供するものである。
まず、化粧料容器本体３内部の密閉性を保持するため該化粧料容器本体３をなす先筒４の開口部５を閉塞するように装着されているキャップ２は、引張することで該化粧料容器本体３の先筒４から脱離し、その開口部５は開口する。
次に、先筒４を持って、軸筒１３を右方向に回転させると、化粧料容器本体３内において該軸筒１３と一体となるネジ筒１８が右回転する。その結果、該ネジ筒１８のネジ溝１９に係合突起２５を遊嵌する回転筒２３は傾斜面１９ａに押勢されて前進し、最終的に該回転筒２３の係合突起２５はネジ溝１９先端の切り欠き溝２０に嵌合するものとなる。このとき、ネジ溝１９の先端はネジ筒１８の先端縁に至っていないことから、ネジ溝１９先端の切り欠き溝２０に嵌合した係合突起２５を有する回転筒２３は、それ以上前進することができなくなる。そして、該回転筒２３の前進に伴って、後端縁を鍔部２７に係止しつつ回転筒２３と一体となる回止筒３３は、その外周面に突設する係止突起３８を先筒４の内周面に刻設する案内溝９内に遊嵌しつつ前進することとなる。そして、該回止筒３３の前進に伴って、回止筒３３と一体となる芯筒６８も前進する。
又、この回転筒２３及び回止筒３３の前進に伴って、回転筒と固定嵌合部１０４により一体となるネジ軸４１と、該ネジ軸４１と雄ネジ部４２及び雌ネジ部６１により螺合して一体となるスリーブ６０と、該スリーブ６０とジョイント６３を介して一体となる芯チャック７２もそれぞれ同時に前進することとなる。その結果、棒状化粧料収容体６７が一体として先筒４の開口部５より突出して固持される。
このとき、回転筒２３の係合突起２５は、ネジ筒１８のネジ溝１９先端の円周方向に設けられた切り欠き溝２０に嵌合しているので、逆に棒状化粧料収容体６７に対して前方からの圧力が作用しても、先筒４の開口部５より突出した棒状化粧料収容体６７が、化粧料容器本体３内へ押し戻されることはない。
その上で、更に軸筒１３を右回転させると、回転筒２３の係合突起２５が、ネジ筒１８の先端縁には至っていないネジ溝１９の切り欠き溝２０に嵌合しているので、回転筒２３の係合突起２５が切り欠き溝２０における傾斜面２０ａにより押勢されるものの、ネジ溝１９自体がそれ以上存在しないことから、軸筒１３と一体となるネジ筒１８と回転筒２３とは共回りすることとなる。このとき、回転筒２３との間で相互に個別回転可能である回転嵌合部１０３によって一体となる回止筒３３は、その先端側に設けられた係止突起３８が先筒４の内周面の案内溝９に遊嵌されているので回転することはなく、回転筒２３だけが該回転嵌合部１０３の摩擦及び回止筒３３の内周面に当接するＯリング２９の摩擦に抗して回転するものとなる。
一方、この回転筒２３の回転は、相互に個別回転不能とする固定嵌合部１０４とともに、径大部２６内において回転筒２３のローレット３２とラチェット機構４６の可動カム４９のローレット５０との噛合により形成される固定噛合部１０５及び、該ラチェット機構４６の可動カム４９内周面のローレット５９とネジ軸４１のローレット４４との噛合により形成される固定噛合部１０８を介して、ネジ軸４１に伝達されるものとなる。ところで、ラチェット機構４６は、回止筒３３内に固持される固定カム４７と、回転筒２３の径大部２６内において該径大部２６との間でスプリング４８を保持する可動カム４９とから構成されているが、該固定カム４７と可動カム４９とは、固定カム４７側に設けられた、後方側から見た際の軸筒１３の回転方向に向くとともに、後方側に向けて立ち上がる斜面５３とその斜面５３に連続する垂直面５４からなるラチェット歯５２と、可動カム４９側に設けられた、前記固定カム４７側における斜面５３に密着する斜面５７と垂直面５８とからなるラチェット歯５６とが互いに噛合しているものである。しかも、可動カム４９はスプリング４８の弾撥力によって前方へ押勢されていることから、軸筒１３を右回転させることで回転筒２３を介して可動カム４９を右方向へ回転させると、該可動カム４９のラチェット歯５６の斜面５７は、回転しない回止筒３３内に固持される固定カム４７のラチェット歯５２の斜面５３によって後方へ向けて押勢されて該斜面５３を乗り越え、その乗り越えた瞬間に前記スプリング４８の弾撥力によって、次のラチェット歯５２と噛合することとなる。即ち、可動カム４９は固定カム４７に対して前後方向への移動を繰り返しながら一方方向へのみ回転（本実施例では後方側から見て右回転）できることになる。そのため、該可動カム４９の内周面のローレット５９と噛合するネジ軸４１のローレット４４により共回りするように形成される固定噛合部１０８を介して、ネジ軸４１は右方向に回転する。
その結果、ネジ軸４１の外周面に螺設される雄ネジ部４２に螺合する雌ネジ部６１を内周面に配設するスリーブ６０は前進し、更には、ジョイント６３を介して一体に連結される棒状化粧料収容体６７内の芯チャック７２が前進するので、該芯チャック７２に保持される棒状化粧料７５は棒状化粧料収容体６７をなす芯筒６８の開口部６８’より突出するものとなる。As mentioned above, since the stick-shaped cosmetic container 1 in the Example of this invention is comprised, a user uses the said stick-shaped cosmetic container 1 for use as follows.
First, the cap 2 mounted so as to close the opening 5 of the tip tube 4 constituting the cosmetic container main body 3 in order to maintain the hermeticity inside the cosmetic container main body 3 is pulled to pull the cosmetic The container body 3 is detached from the front tube 4 and the opening 5 is opened.
Next, when the shaft tube 13 is rotated rightward with the leading tube 4, the screw tube 18 integrated with the shaft tube 13 rotates clockwise in the cosmetic container body 3. As a result, the rotary cylinder 23 in which the engagement protrusion 25 is loosely fitted in the screw groove 19 of the screw cylinder 18 moves forward while being pushed by the inclined surface 19a, and finally the engagement protrusion 25 of the rotary cylinder 23 becomes the screw groove. 19 is fitted into the notch groove 20 at the tip. At this time, since the tip of the screw groove 19 does not reach the tip edge of the screw cylinder 18, the rotary cylinder 23 having the engagement protrusion 25 fitted to the notch groove 20 at the tip of the screw groove 19 advances further. Can not be. As the rotary cylinder 23 moves forward, the stop cylinder 33 integrated with the rotary cylinder 23 while locking the rear end edge to the flange portion 27 has a locking projection 38 protruding from the outer peripheral surface thereof. It advances while loosely fitting in the guide groove 9 carved in the inner peripheral surface of the cylinder 4. Then, as the rotation cylinder 33 advances, the core cylinder 68 integrated with the rotation cylinder 33 also advances.
Further, as the rotary cylinder 23 and the stop cylinder 33 move forward, the screw shaft 41 integrated by the rotary cylinder and the fixed fitting portion 104, and the screw shaft 41, the male screw portion 42, and the female screw portion 61 are screwed. The integrated sleeve 60 and the core chuck 72 integrated with the sleeve 60 and the joint 63 also advance simultaneously. As a result, the stick-shaped cosmetic container 67 is integrally protruded and fixed from the opening 5 of the front tube 4.
At this time, the engagement protrusion 25 of the rotating cylinder 23 is fitted in the notch groove 20 provided in the circumferential direction at the tip of the screw groove 19 of the screw cylinder 18, so that the bar-shaped cosmetic container 67 is conversely arranged. On the other hand, even if pressure from the front acts, the bar-shaped cosmetic container 67 protruding from the opening 5 of the front tube 4 is not pushed back into the cosmetic container body 3.
Then, when the shaft cylinder 13 is further rotated to the right, the engagement protrusion 25 of the rotating cylinder 23 is fitted into the notch groove 20 of the screw groove 19 that does not reach the tip edge of the screw cylinder 18. Although the engagement protrusion 25 of the rotary cylinder 23 is urged by the inclined surface 20a in the notch groove 20, there is no further screw groove 19 itself, so that the screw cylinder 18 and the rotary cylinder 23 integrated with the shaft cylinder 13 are present. And will be co-rotating. At this time, the rotation cylinder 33 integrated with the rotation fitting portion 103 that can be individually rotated with the rotation cylinder 23 has a locking projection 38 provided on the tip side thereof so that the inner periphery of the front cylinder 4 is provided. Since it is loosely fitted in the guide groove 9 on the surface, it does not rotate, and only the rotary cylinder 23 resists the friction of the rotary fitting portion 103 and the friction of the O-ring 29 that contacts the inner peripheral surface of the stop cylinder 33. And rotate.
On the other hand, the rotation of the rotating cylinder 23 meshes with the knurled portion 32 of the rotating cylinder 23 and the knurled 50 of the movable cam 49 of the ratchet mechanism 46 in the large-diameter portion 26 together with the fixed fitting portions 104 that cannot mutually rotate. The screw shaft 41 is fixed to the screw shaft 41 via the fixed engagement portion 105 formed by the engagement between the knurling 59 of the inner periphery of the movable cam 49 of the ratchet mechanism 46 and the knurling 44 of the screw shaft 41. Will be communicated. By the way, the ratchet mechanism 46 includes a fixed cam 47 that is held in the rotation cylinder 33 and a movable cam 49 that holds a spring 48 between the large diameter part 26 in the large diameter part 26 of the rotary cylinder 23. Although it is configured, the fixed cam 47 and the movable cam 49 are inclined surfaces that are provided on the fixed cam 47 side and face the rotation direction of the shaft tube 13 when viewed from the rear side and rise toward the rear side. 53, a ratchet tooth 52 comprising a vertical surface 54 continuous with the slope 53, and a ratchet tooth 56 comprising a slope 57 and a vertical surface 58, which are provided on the movable cam 49 side and are in close contact with the slope 53 on the fixed cam 47 side. Are meshed with each other. Moreover, since the movable cam 49 is urged forward by the elastic force of the spring 48, when the movable cam 49 is rotated to the right via the rotating cylinder 23 by rotating the shaft cylinder 13 to the right, The inclined surface 57 of the ratchet tooth 56 of the movable cam 49 is pushed backward by the inclined surface 53 of the ratchet tooth 52 of the fixed cam 47 fixed in the non-rotating stop cylinder 33 to get over the inclined surface 53. At the moment, the next ratchet teeth 52 are engaged by the elastic force of the spring 48. That is, the movable cam 49 can rotate only in one direction while repeating the movement in the front-rear direction with respect to the fixed cam 47 (in this embodiment, it can rotate rightward when viewed from the rear side). Therefore, the screw shaft 41 rotates in the right direction via the fixed engagement portion 108 formed so as to rotate together with the knurling 44 of the screw shaft 41 meshing with the knurling 59 on the inner peripheral surface of the movable cam 49.
As a result, the sleeve 60 in which the female screw portion 61 screwed to the male screw portion 42 screwed to the outer peripheral surface of the screw shaft 41 is advanced on the inner peripheral surface is advanced, and further, the sleeve 60 is integrally formed via the joint 63. Since the core chuck 72 in the bar-shaped cosmetic container 67 to be connected advances, the bar-shaped cosmetic 75 held by the core chuck 72 protrudes from the opening 68 ′ of the core cylinder 68 that forms the bar-shaped cosmetic container 67. To be.

また、使用後には、先筒４を持って、軸筒１３を逆回転（本実施例では左回転）させると、まず回転筒２３の係合突起２５とネジ筒１８のネジ溝１９先端の切り込み溝２０との嵌合が解除される。
そしてさらに軸筒１３を逆回転させることによって、該軸筒１３と一体となるネジ筒１８のネジ溝１９が、遊嵌して一体となる回転筒２３の係合突起２５を案内しつつ回転することとなるので、回転筒２３は化粧料容器本体３内を後退する。このとき、回転筒２３と回止筒３３とは離脱不能である回転嵌合部１０３によって一体となるとともに、回止筒３３と棒状化粧料収容体６７の芯筒６８も固定嵌合部１０６によって一体となっている。又、同時に、回転筒２３と固定嵌合部１０４により一体となるネジ軸４１は、雄ネジ部４２及び雌ネジ部６１の螺合によりスリーブ６０と一体となり、更に該スリーブ６０は、ジョイント６３を介して芯チャック７２と一体となっている。その結果、前記回転筒２３の後退に伴って回止筒３３とともに、棒状化粧料収容体６７全体が化粧料容器本体３内を後退する。その結果、棒状化粧料収容体６７は迅速に化粧料容器本体３内に没入するものとなる。After use, when the shaft cylinder 13 is rotated in the reverse direction (left rotation in this embodiment) by holding the leading cylinder 4, first, the engagement protrusion 25 of the rotating cylinder 23 and the tip of the thread groove 19 of the screw cylinder 18 are cut. The fitting with the groove 20 is released.
Then, by further rotating the shaft tube 13 in the reverse direction, the screw groove 19 of the screw tube 18 integrated with the shaft tube 13 rotates while guiding the engagement protrusion 25 of the rotary tube 23 integrated by loose fitting. Therefore, the rotary cylinder 23 moves backward in the cosmetic container body 3. At this time, the rotating cylinder 23 and the rotating cylinder 33 are integrated by the rotation fitting part 103 that cannot be detached, and the rotating cylinder 33 and the core cylinder 68 of the bar-shaped cosmetic container 67 are also fixed by the fixed fitting part 106. It is united. At the same time, the screw shaft 41 integrated by the rotating cylinder 23 and the fixed fitting portion 104 is integrated with the sleeve 60 by the screwing of the male screw portion 42 and the female screw portion 61, and the sleeve 60 further connects the joint 63. Via the core chuck 72. As a result, along with the retraction of the rotating cylinder 23, the entire stick-shaped cosmetic container 67 retreats inside the cosmetic container body 3 together with the rotation cylinder 33. As a result, the stick-shaped cosmetic container 67 quickly immerses in the cosmetic container body 3.

なお、この軸筒１３の逆回転（本実施例においては左回転）によって、回転筒２３の係合突起２５がネジ筒１８のネジ溝１９後端に至った後、更に軸筒１３を逆回転させようとしても、回転筒２３とネジ軸４１との間に介在するラチェット機構４６によって、その回転が防止される。すなわち、該ラチェット機構４６を構成する固定カム４７は、その凹凸部５１が回止筒３３の凹凸部３９と係合し、更にその回止筒３３はその先端側に設けられた係止突起３８が先筒４の案内溝９に遊嵌していることから、回転作動しないものである。しかし、上述のように固定カム４７のラチェット歯５２の斜面５３と、可動カム４９のラチェット歯５６の斜面５７とが対向して噛合していることから、可動カム４９が右回転する場合には、固定カム４７に対して可動カム４９がスプリング４８の圧縮、伸長を伴いながら回転しうることとなる。それに対して可動カム４９が逆回転（本実施例においては左回転）しようとする場合には、固定カム４７のラチェット歯５２の垂直面５４と可動カム４９の垂直面５８とが当接することから、固定カム４７によって規制されることとなり、可動カム４９の逆回転（本実施例においては左回転）は不能となる。その結果、軸筒１３を逆回転（本実施例においては左回転）させても、ネジ筒１８によって回転筒２３が後退することができる以上には回転筒２３を回転することができないこととなる。そのため、棒状化粧料収容体６７の芯筒６８において棒状化粧料７５を保持する芯チャック７２がネジ軸４１の逆回転によって後退することはなく、該棒状化粧料７５の芯筒６８内への没入に伴う棒状化粧料７５の破損を防止できるものである。 The shaft cylinder 13 is further rotated in the reverse direction after the engaging protrusion 25 of the rotating cylinder 23 reaches the rear end of the screw groove 19 of the screw cylinder 18 by the reverse rotation of the shaft cylinder 13 (left rotation in this embodiment). Even if it tries to make it, the rotation is prevented by the ratchet mechanism 46 interposed between the rotary cylinder 23 and the screw shaft 41. That is, the fixed cam 47 constituting the ratchet mechanism 46 has its concavo-convex portion 51 engaged with the concavo-convex portion 39 of the stop cylinder 33, and the stop cylinder 33 is further provided with a locking projection 38 provided on the tip side thereof. Is loosely fitted in the guide groove 9 of the front tube 4 and therefore does not rotate. However, since the inclined surface 53 of the ratchet teeth 52 of the fixed cam 47 and the inclined surface 57 of the ratchet teeth 56 of the movable cam 49 are engaged with each other as described above, when the movable cam 49 rotates to the right. The movable cam 49 can rotate with respect to the fixed cam 47 while the compression and extension of the spring 48 are involved. On the other hand, when the movable cam 49 tries to rotate in the reverse direction (left rotation in this embodiment), the vertical surface 54 of the ratchet teeth 52 of the fixed cam 47 and the vertical surface 58 of the movable cam 49 come into contact with each other. Therefore, the fixed cam 47 restricts the reverse movement of the movable cam 49 (left rotation in this embodiment). As a result, even if the shaft cylinder 13 is rotated in the reverse direction (left rotation in this embodiment), the rotating cylinder 23 cannot be rotated more than the rotating cylinder 23 can be retracted by the screw cylinder 18. . Therefore, the core chuck 72 that holds the bar-shaped cosmetic 75 in the core cylinder 68 of the bar-shaped cosmetic container 67 is not retracted by the reverse rotation of the screw shaft 41, and the bar-shaped cosmetic 75 is immersed in the core cylinder 68. It is possible to prevent damage to the bar-shaped cosmetic material 75 due to the above.
