【０００１】
【発明の属する技術分野】
この発明は、アイライナー、アイブロー、アイシャドウ及び口紅等の細径でしかも揮発成分を有する棒状化粧料を収容する化粧料容器に関する。
【０００２】
【従来の技術】
従来、アイライナー、アイブロー、アイシャドウ及び口紅等の細径で、しかも揮発成分を有する棒状化粧料を収容する化粧料容器において、この化粧料容器内に収容する棒状化粧料を、上記軸筒を回動自在に保持する芯筒先端の開口部から出没させるにあたっては、軸筒を回動させることで、この軸筒内において一体に固持されたネジ駒に対して、その表面に螺設されたネジを噛合させる押棒を前進或は後退させて行う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、上記従来のように、軸筒の回動により、この軸筒内において一体に固持されたネジ駒に対して、その表面に螺設されたネジを噛合させる押棒を前進或は後退させて棒状化粧料を出没させてなるものの場合、その構造上芯筒内壁面全体には、例えば棒状化粧料を保持する受皿体が上記押棒の回動に合わせて回動することなく芯筒内を前進或は後退するように回り止め溝が配設されることとなり、このとき軸筒が容易に回動して化粧料容器内に収容する棒状化粧料が不用意に軸筒に保持される芯筒先端の開口部より突出して他所への汚損等が発生することを防止できるように、軸筒に対してスライド抵抗を与えようとすると、上記棒状化粧料を保持する受皿体の回動方向或は前進或は後退するスライド方向に弾性体を配置せざるを得なくなり、製造工程が複雑となる上に、棒状化粧料が不用意に軸筒に保持される芯筒先端の開口部より突出して他所への汚損等の発生に確実に防止することができないという欠点がある。
【０００４】
更に、化粧料容器内に収容されている棒状化粧料が、アイライナー、アイブロー、アイシャドウ及び口紅等の細径でしかも揮発成分を有するものである場合には、化粧料容器内での気密性を確保する必要があるが、芯筒内壁面全体には、例えば棒状化粧料を保持する受皿体が上記押棒の回動に合わせて回動することなく芯筒内を前進或は後退するように回り止め溝が配設されているため十分な気密性の維持を確保することができず、化粧料自体の品質の低下を招いてしまうという問題がある。
【０００５】
また、棒状化粧料を保持する受皿体と一体となる軸筒の回動に対して、この軸筒内に固持するネジ駒に噛合すると共に、その回動に合わせて前進或は後退する押棒においては、軸筒の過剰な回動により押棒がネジ駒との噛合範囲を超えて前進或は後退しすぎて、押棒表面に螺設されるネジとネジ駒との噛合が解離し、受皿体に保持される棒状化粧料の化粧料容器に対する出没操作が不能となってしまうことを防止するために、上記押棒に対して過剰な前進或は後退を防止するストッパーが設けられているが、このストッパーは通常押棒において過剰な前進或は後退のいずれか一方を防止するためにしか設けられていないため、その目的以外の操作、すなわち軸筒の回動により押棒が過剰に後退或は前進してしまうと、軸筒内に固持されるネジ駒と、押棒表面に螺設されるネジとネジ駒との噛合が解離し、受皿体に保持される棒状化粧料の化粧料容器に対する出没操作が不能となる問題もある。
【０００６】
そこで、この発明は上記従来のものの持つ欠点を改善するものであり、簡単な構造により、軸筒の回動によって不用意に棒状化粧料が化粧料容器内から突出して他所を汚損することを防止するためのスライド抵抗の付与及び、化粧料容器内での気密性を十分な確保と共に、棒状化粧料の出没操作に対しての破損の発生を阻止することができるようにするものである。
【０００７】
【課題を解決するための手段】
そのために、芯筒に対して回動自在に保持される軸筒並びに、上記芯筒内に、後端縁にストッパーを配設した上、その外表面にネジを螺設する押棒及び棒状化粧料を保持する芯チャック部、及びその芯チャック部の後端外周に周設する係止溝内にＯリングを保持してなるストッパーリングを一体に構成し、上記芯筒の前方内壁面に軸方向に案内溝を溝設すると共に、この案内溝内に棒状化粧料を保持する芯チャック部を遊嵌し軸筒内において一体に固持されるネジ駒の回動により、上記軸筒内に固持され押棒のネジと噛合うネジ駒の回動により、芯チャック部内に保持される棒状化粧料を、芯筒の先端の開口部より出没自在とし、該芯筒先端に嵌着するキャップを、弾性を有する内キャップにより、上記芯筒先端の開口部を閉塞するように一体に嵌着してなるものである。
【０００８】
【発明の実施の形態】
この発明を実施するにあたって、芯筒の前方内壁面に軸方向に溝設される案内溝は上記芯筒の前方内壁面にしかなく、また軸筒内に固持されるネジ駒と噛合して前後に進退自在となる押棒及び棒状化粧料を保持してなる芯チャック部と一体のストッパーリングの係止溝内に保持するＯリングが芯筒の内壁面に密接するので、軸筒の回動に対してのスライド抵抗を与えることができると共に、気密性を十分に確保することができる上、棒状化粧料を保持する芯チャック部と一体の押棒の外表面に螺設するネジがネジ駒のネジと噛合し、その軸筒内に固持されたネジ駒のネジ駒両端面に対して、押棒が前進する時には押棒の後端縁に配設するストッパーが、反対に押棒が後退する時には化粧料保持体を構成する芯チャック部のストッパーリングが当接、係止するものとなるので、軸筒を過剰に回動しても押棒自体はそれ以上前進或は後退することができなくなることから、軸筒内に固持されるネジ駒と押棒表面に螺設されるネジとの噛合が解離して、芯チャック部に保持される棒状化粧料の化粧料容器に対する出没操作の安全性が確保できなくなることを防止できる。なお、上記案内溝はひとつの溝でもよいが、断面十字状あるいは適宜対向して複数設けることにより芯チャック部の摺動を円滑に行うことができる。
【０００９】
更に、上記棒状化粧料を収容する軸筒を回動自在に装着してなる芯筒先端に嵌着するキャップを、弾性を有する内キャップにより、上記芯筒先端の開口部を閉塞するように一体に嵌着してなるものとし、棒状化粧料容器のみならず、化粧料容器内に収容する棒状化粧料が出没する芯筒の先端の開口部を完全に閉塞することができるので、化粧料容器として使用していない場合は、キャップの内キャップが芯筒の先端に弾性をもって一体嵌着され、化粧料容器内の気密性を確実に確保することができる上、化粧料の消耗にしたがい、Ｏリングも前進するので気密部分を化粧料に対して有効に作用できる。
【００１０】
【実施例】
この発明を図に示す実施例により更に説明する。図１において示されるのは、この発明の実施例である棒状化粧料容器（１）であり、この棒状化粧料容器（１）は、先端にキャップ（１９）を嵌着する芯筒（６）に対して回動自在に保持され、後端に通気孔（５）を有する軸筒（２）及び、上記軸筒（２）を回動自在に保持する芯筒（６）内において、押棒（１１）の後端縁にストッパー（１２）とスリット割（２２）を配設した上、その外表面にネジ（１３）を螺設する押棒（１１）及び棒状化粧料（１５）を保持する芯チャック部（１４）、更に芯チャック部（１４）の後端外周に周設する係止溝（１７）内にＯリング（１８）を保持してストッパーリング（１６）を一体に構成して化粧料保持体（１０）としてなるものである。なお、押棒（１１）後端に軸方向にスリットを入れてスリット割（２２）を形成し、作動時、ストッパー（１２）の摺動を円滑に行うことができる。
【００１１】
そして、上記棒状化粧料容器（１）を構成する芯筒（６）の前方内壁面（８’）において軸方向互いに対向するように断面十字状の案内溝（９）を溝設すると共に、この案内溝（９）内に棒状化粧料（１５）を保持する芯チャック部（１４）を摺動自在に遊嵌することで、ストッパーリング（１６）の係止溝（１７）内に保持するＯリング（１８）を芯筒（６）の内壁面（８）に密接させつつ軸筒（２）内に固持されるネジ駒（３）の回動により、上記ネジ駒（３）のネジ溝（４）と外表面に螺設するネジ（１３）との噛合により進退自在となる押棒（１１）と一体の芯チャック部（１４）内に保持される棒状化粧料（１５）を、芯筒（６）の先端の開口部（７）より出没自在としてなるものである。
【００１２】
この発明の実施例である棒状化粧料容器（１）は以上の構成を具えるので、軸筒（２）の回動により、この回動する軸筒（２）内に固持されるネジ駒（３）と噛合する化粧料保持体（１０）を構成する押棒（１１）と一体に成形され、棒状化粧料（１５）を保持する芯チャック部（１４）の回転を抑止し、円滑な化粧料保持体（１０）の前進或は後退を案内する芯筒（６）の内壁面（８）に十字状に溝設される案内溝（９）は、上記芯筒（６）の前方内壁面（８’）にのみ設け、ストッパーリング（１６）と重なることがないので密封状態が保持され、また軸筒（２）内に固持されるネジ駒（３）と噛合して前後に進退自在となる押棒（１１）及び棒状化粧料（１５）を保持してなる芯チャック部（１４）と共に一体に成形されるストッパーリング（１６）の係止溝（１７）内に保持するＯリング（１８）が、芯筒（６）の案内溝（９）より後方部分の内壁面（８）に常に密接しているので、まず不用意な軸筒（２）の回動による容器（１）内からの棒状化粧料（１５）の突出により生じる他所への汚損等を防止するため、軸筒（２）の回動に対して適当なスライド抵抗を与えることができると共に、上記ストッパーリング（１６）の係止溝（１７）内に保持するＯリング（１８）は化粧料保持体（１０）の前後方向へのスライドに対しても常に芯筒（６）の内壁面（８）へ密接しているものとなるので、軸筒（２）の後端に穿設される通気孔（５）の存在にも関わらず、上記棒状化粧料容器（１）内の気密性を十分に確保することができる。
【００１３】
更に、棒状化粧料（１５）を保持する芯チャック部（１４）と一体の押棒（１１）の外表面に螺設するネジ（１３）が噛合してなる軸筒（２）内に固持されたネジ駒（３）のネジ駒両端面（３’）（３”）に対して、上記軸筒（２）の回動によりこの軸筒（２）内に固持されるネジ駒（３）に噛合する押棒（１１）が棒状化粧料（１５）を芯筒（６）の開口部（７）より突出させるため、前進する時には押棒（１１）の後端縁に配設するストッパー（１２）が、反対に棒状化粧料（１５）を化粧料容器（１）内に収容ために押棒（１１）が後退する時には化粧料保持体（１０）を構成するストッパーリング（１６）が、上記ネジ駒（３）の後端面（３”）又は前端面（３’）にそれぞれ当接、係止するものとなるので、この発明の実施例である化粧料容器（１）内に収容されている棒状化粧料（１５）の出没操作を行うにあたって、軸筒（２）を過剰に回動してしまっても、この軸筒（２）内に固持されるネジ駒（３）と噛合する押棒（１１）自体はそのネジ駒（３）の両端面（３’）（３”）との当接位置以上は前進或は後退することができなくなり、軸筒（２）内に固持されるネジ駒（３）のネジ溝（４）と、押棒（１１）表面に螺設されるネジ（１３）との噛合が解離してしまい、芯チャック部（１４）に保持される棒状化粧料（１５）の化粧料容器（１）を構成する芯筒（６）の開口部（７）に対する出没操作が行えなくなるという不具合を防止する、すなわち容器の安全性を確保できるものである。なお、押棒（１１）のストッパー（１２）がネジ駒（３）の後端面（３”）に当接する位置において、ストッパーリング（１６）が位置する案内溝（９）内に芯筒内ストッパー（２３）を突設することにより、押棒（１１）のストッパー（１２）がネジ駒（３）の後端面（３”）に当接すると同時に、ストッパーリング（１６）が芯筒内ストッパー（２３）に当接して、より確実に安全性を確保できる。
【００１４】
また、上記実施例の化棒状化粧料容器（１）を構成する芯筒（６）の先端の開口部（７）に対して嵌着されるキャップ（１９）は弾性を有する内キャップ（２０）を内設することで、上記芯筒（６）先端の開口部（７）を確実に閉塞するように一体に嵌着しようとするものである。そのため、この内キャップ（２０）を有するキャップ（１９）は、使用していない場合は、キャップ（１９）の内キャップ（２０）が芯筒（６）先端の開口部（７）に対して弾性をもって一体に嵌着されるものとなるので、ストッパーリング（１６）の係止溝（１７）内に保持するＯリング（１８）の芯筒（６）の内壁面（８）への密接と共に、化粧料容器（１）内の気密性を確実に確保することができるものとなる。
【００１５】
【発明の効果】
以上のとおり、棒状化粧料を芯筒の先端の開口部から出没させるにあたって、後端縁にストッパーを配設する押棒とこの押棒と一体の芯チャック部のストッパーリングの係止溝内にＯリングを保持させ、また上記棒状化粧料を収容する軸筒を回動自在に装着してなる芯筒先端に嵌着するキャップに弾性を有する内キャップを設けることで、まず容器内に収容する棒状化粧料の出没操作に当たって、上記棒状化粧料の出没操作が不能となってしまうことを防止できると共に、常に芯筒の内壁面に当接するストッパーリングのＯリング及び出没する棒状化粧料を保持する芯チャック部の案内をする案内溝を最小限とし、更に化粧料容器内の気密性は確実に維持できるものとなり、揮発成分を有する化粧料の品質の低下を防ぐこともできるという優れた効果を有するものである。

BACKGROUND OF THE INVENTION
The present invention relates to a cosmetic container that contains a rod-shaped cosmetic having a small diameter and having a volatile component, such as an eyeliner, eyebrow, eyeshadow, and lipstick.
[0002]
[Prior art]
Conventionally, in a cosmetic container containing a rod-shaped cosmetic having a small diameter and having a volatile component, such as an eyeliner, eyebrow, eyeshadow, and lipstick, the rod-shaped cosmetic stored in the cosmetic container is replaced with the shaft cylinder. When protruding and retracting from the opening at the tip of the core cylinder that is rotatably held, the shaft cylinder is rotated so that the screw piece fixed integrally in the shaft cylinder is screwed on the surface thereof. In general, the push rod for engaging the screw is moved forward or backward.
[0003]
[Problems to be solved by the invention]
However, as in the prior art, the push rod for engaging the screw screwed on the surface of the screw piece fixed integrally in the shaft cylinder is moved forward or backward by the rotation of the shaft cylinder. In the case where the bar-shaped cosmetic is made to appear and disappear, the entire inner wall surface of the core cylinder is structurally moved forward in the core cylinder without rotating, for example, the tray body holding the bar-shaped cosmetic according to the rotation of the push bar. Alternatively, a non-rotating groove is disposed so as to retreat, and at this time, the shaft cylinder easily rotates, and the core cylinder in which the rod-shaped cosmetic material accommodated in the cosmetic container is inadvertently held by the shaft cylinder If the slide resistance is applied to the shaft tube so that it can be prevented from projecting from the opening at the tip and causing contamination to other places, the rotating direction of the tray body holding the bar-shaped cosmetic material or An elastic body must be placed in the sliding direction to move forward or backward The manufacturing process is complicated, and the stick-shaped cosmetics are inadvertently protruded from the opening at the tip of the core cylinder held by the shaft cylinder, and it is impossible to reliably prevent the occurrence of contamination to other places. There is.
[0004]
Furthermore, when the stick-shaped cosmetic contained in the cosmetic container has a small diameter and a volatile component such as an eyeliner, eyebrow, eyeshadow and lipstick, the airtightness in the cosmetic container However, on the entire inner wall surface of the core cylinder, for example, the tray body holding the bar-shaped cosmetic is moved forward or backward in the core cylinder without rotating in accordance with the rotation of the push bar. Since the anti-rotation groove is provided, sufficient airtightness cannot be maintained, and there is a problem that the quality of the cosmetic itself is deteriorated.
[0005]
In addition, with respect to the rotation of the shaft tube integrated with the saucer body holding the bar-shaped cosmetic material, the push rod that meshes with the screw piece fixed in the shaft tube and moves forward or backward in accordance with the rotation. The push rod moves forward or backward beyond the engagement range with the screw piece due to excessive rotation of the shaft cylinder, and the engagement between the screw screwed on the surface of the push rod and the screw piece is dissociated, and the tray body A stopper for preventing excessive advance or retreat of the push bar is provided in order to prevent the bar-shaped cosmetic to be held from appearing and retracting with respect to the cosmetic container. Is usually provided only to prevent either excessive advancement or retraction of the push rod, so that the push rod is excessively retracted or advanced by an operation other than that purpose, that is, rotation of the shaft cylinder. And a screw that is held inside the barrel If, dissociated engagement between the screw and the screw piece which is screwed to the push rod surface, there is also infested operation becomes impossible problem for cosmetic container of the stick-shaped cosmetic material held in the pan body.
[0006]
Therefore, the present invention improves the above-mentioned disadvantages of the conventional one, and prevents the stick-shaped cosmetic material from inadvertently protruding from the cosmetic container due to the rotation of the shaft tube and defaced elsewhere. It is possible to prevent the occurrence of breakage of the stick-shaped cosmetic material from appearing and moving, while providing sufficient sliding resistance and ensuring airtightness in the cosmetic container.
[0007]
[Means for Solving the Problems]
Therefore, a shaft cylinder that is rotatably held with respect to the core cylinder, and a push bar and a rod-shaped cosmetic material in which a stopper is disposed at the rear end edge in the core cylinder and a screw is screwed on the outer surface thereof. And a stopper ring formed by holding an O-ring in a locking groove provided around the rear end outer periphery of the core chuck portion, and integrally formed on the front inner wall surface of the core cylinder in the axial direction The guide groove is formed in the guide groove, and the core chuck portion holding the rod-shaped cosmetic is loosely fitted in the guide groove, and the push rod is fixed in the shaft cylinder by the rotation of the screw piece fixed integrally in the shaft cylinder. By rotating the screw piece that meshes with the screw, the rod-shaped cosmetic material held in the core chuck portion can be made to appear and disappear from the opening at the tip of the core tube, and the cap fitted to the tip of the core tube has an elastic inner Use a cap to close the opening at the tip of the core tube. It is made to fit in.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
In carrying out the present invention, the guide groove formed in the axial direction on the front inner wall surface of the core tube is only on the front inner wall surface of the core tube, and is engaged with the screw piece fixed in the shaft tube. The O-ring held in the locking groove of the stopper ring integral with the core chuck portion holding the push rod and the rod-shaped cosmetic material that can be moved forward and backward is in close contact with the inner wall surface of the core tube, so that the shaft tube can be rotated. In addition to providing a sliding resistance, the airtightness can be sufficiently secured, and the screw that is screwed on the outer surface of the push bar integrated with the core chuck portion that holds the bar-shaped cosmetic is the screw of the screw piece. When the push bar moves forward with respect to both end faces of the screw piece that is engaged and held in the shaft cylinder, the stopper disposed on the rear edge of the push bar is opposite, and when the push bar moves backward, the cosmetic holder is The stopper ring of the core chuck part Since the push rod itself can no longer be moved forward or backward even if the shaft tube is excessively rotated, the screw piece and the push rod surface held in the shaft tube cannot be moved. It can be prevented that the engagement with the screw to be screwed is dissociated and the safety of the protruding and retracting operation of the bar-shaped cosmetic held on the core chuck portion with respect to the cosmetic container cannot be secured. Although the guide groove may be a single groove, the core chuck portion can be smoothly slid by providing a plurality of cross-shaped cross sections or a plurality of the guide grooves appropriately facing each other.
[0009]
Further, a cap that is fitted to the tip of the core cylinder that is rotatably mounted with the shaft cylinder that houses the bar-shaped cosmetic is integrated so as to close the opening at the tip of the core cylinder with an elastic inner cap. It is possible to completely close not only the bar-shaped cosmetic container but also the opening at the tip of the core cylinder in which the bar-shaped cosmetic accommodated in the cosmetic container appears and disappears. When the cap is not used, the inner cap of the cap is elastically and integrally fitted to the tip of the core tube, so that airtightness in the cosmetic container can be reliably ensured, and the cosmetic is consumed according to O Since the ring also moves forward, the airtight part can effectively act on the cosmetic.
[0010]
【Example】
The present invention will be further described with reference to the embodiments shown in the drawings. FIG. 1 shows a stick-shaped cosmetic container (1) according to an embodiment of the present invention. The stick-shaped cosmetic container (1) has a core cylinder (6) in which a cap (19) is fitted at the tip. In the shaft cylinder (2) having a vent hole (5) at the rear end and the core cylinder (6) holding the shaft cylinder (2) in a rotatable manner. 11) A stopper (12) and a slit split (22) are arranged on the rear end edge, and a push rod (11) for screwing a screw (13) on its outer surface and a core for holding a bar-shaped cosmetic (15) The stopper ring (16) is constructed integrally by holding the O-ring (18) in the chuck groove (14) and the locking groove (17) provided around the outer periphery of the rear end of the core chuck part (14). As a material holder (10). The slit (22) is formed by making a slit in the axial direction at the rear end of the push rod (11), and the stopper (12) can be smoothly slid during operation.
[0011]
Then, a guide groove (9) having a cross-shaped cross section is formed in the front inner wall surface (8 ′) of the core cylinder (6) constituting the rod-shaped cosmetic container (1) so as to face each other in the axial direction. The core chuck portion (14) that holds the bar-shaped cosmetic material (15) in the guide groove (9) is slidably loosely fitted, so that it is held in the locking groove (17) of the stopper ring (16). By rotating the screw piece (3) fixed in the shaft cylinder (2) while bringing the ring (18) into close contact with the inner wall surface (8) of the core cylinder (6), 4) and a rod-shaped cosmetic material (15) held in a core chuck portion (14) integrated with a push rod (11) which can be moved forward and backward by meshing with a screw (13) screwed on the outer surface, It can be made to appear and disappear from the opening (7) at the tip of 6).
[0012]
Since the stick-shaped cosmetic container (1) according to the embodiment of the present invention has the above-described configuration, the screw piece (in the rotating barrel (2) is held by the pivot (2). 3) Smooth cosmetic that is molded integrally with the push rod (11) that constitutes the cosmetic holder (10) that meshes with 3) and suppresses the rotation of the core chuck portion (14) that holds the stick cosmetic (15). A guide groove (9) formed in a cross-like shape on the inner wall surface (8) of the core tube (6) for guiding the holding body (10) to advance or retreat is provided on the front inner wall surface ( 8 ') and is not overlapped with the stopper ring (16), so that the sealed state is maintained, and the screw piece (3) held in the shaft cylinder (2) is engaged and can be moved forward and backward. Stopper which is integrally formed with the core chuck portion (14) which holds the push rod (11) and the bar-shaped cosmetic (15).

In addition, the cap (19) fitted to the opening (7) at the tip of the core tube (6) constituting the chemical rod-shaped cosmetic container (1) of the above embodiment is an inner cap (20) having elasticity. Is intended to be integrally fitted so as to reliably close the opening (7) at the tip of the core tube (6). Therefore, when the cap (19) having the inner cap (20) is not used, the inner cap (20) of the cap (19) is elastic with respect to the opening (7) at the tip of the core tube (6). So that the O-ring (18) held in the locking groove (17) of the stopper ring (16) is closely attached to the inner wall surface (8) of the core tube (6). The airtightness in the cosmetic container (1) can be reliably ensured.
