Abstract

<P>PROBLEM TO BE SOLVED: To prevent a stick-shaped cosmetic container body from being broken with simple structure even if the rotary operation of an axial cylinder is excessively performed in projecting/retracting a stick-shaped cosmetic, and also to warn a user against the excessive operation. <P>SOLUTION: A chuck shaft 19 to be slid in a front and rear direction with the rotation of a screw piece 14 is composed of a chuck part 20; a male thread part 25; and a spring part 27 arranged between them. A distance between the most front end screw thread and the most rear end screw thread in the male thread part is set to be a little longer than the slidable distance in the front and rear direction of the chuck part. Thus, even if the shaft cylinder is excessively rotated, disengagement between the screw piece and the male thread part, and re-engagement involving click sound caused by the repulsive force of the spring part are repeated. <P>COPYRIGHT: (C)2008,JPO&INPIT

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た棒状化粧料を出没自在に収容する棒状化粧料容器に関する。   The present invention relates to a bar-shaped cosmetic container that removably accommodates a bar-shaped cosmetic having a reduced diameter, such as an eyebrow, eyeliner, eye shadow, or lip liner.

従来より、例えば上記各種棒状化粧料を出没自在に収容する棒状化粧料容器は、棒状化粧料を保持する芯チャックをネジ機構を利用して容器本体内で前後方向に摺動して、棒状化粧料を棒状化粧料容器内外に出没させるものである。   2. Description of the Related Art Conventionally, for example, a rod-shaped cosmetic container that accommodates the above-described various bar-shaped cosmetics in a retractable manner is a rod-shaped cosmetic by sliding a core chuck holding the rod-shaped cosmetic in the container body in the front-rear direction using a screw mechanism. The material is made to appear in and out of the stick-shaped cosmetic container.

例えば、該棒状化粧料容器は、内壁面に案内溝を溝設する芯筒、ネジ駒を固持する軸筒、及び棒状化粧料を保持するとともに芯チャックと一体となり、その外周面にネジ駒と噛合するネジ部を螺設する押棒から構成するものとした上で、押棒と一体となる芯チャック部の外周面にストッパーリングを装着するとともに、該押棒の後端縁にはストッパーを配設してなるものである。そして該棒状化粧料容器において、軸筒を回転させることで軸筒内で固持されるネジ駒も共回りして、該ネジ駒と噛合する押棒が棒状化粧料容器内を前後方向に摺動することで、該押棒と一体となる芯チャック部に保持された棒状化粧料が芯筒の開口部より出没するものである（特許文献１参照）。   For example, the stick-shaped cosmetic container has a core cylinder having a guide groove on the inner wall surface, a shaft cylinder that holds the screw piece, and a stick-shaped cosmetic that is integrated with the core chuck and has a screw piece on the outer peripheral surface thereof. The engaging screw part is composed of a push rod that is screwed, and a stopper ring is attached to the outer peripheral surface of the core chuck portion that is integral with the push rod, and a stopper is disposed on the rear edge of the push rod. It will be. Then, in the bar-shaped cosmetic container, the screw piece fixed in the shaft cylinder is rotated together by rotating the shaft cylinder, and the push bar engaged with the screw piece slides in the front-rear direction in the bar-shaped cosmetic container. As a result, the bar-shaped cosmetic material held by the core chuck unit integral with the push bar appears and disappears from the opening of the core cylinder (see Patent Document 1).

ところで、上記棒状化粧料容器では、棒状化粧料の出没操作時に、軸筒を過剰に回転させることで押棒が前後方向に摺動しすぎて押棒とネジ駒との噛合が解離し、棒状化粧料の出没操作が行えなくなることを防止するために、上記押棒と一体となる芯チャック部の外周面にはストッパーリングが、又、押棒の後端縁にはストッパーがそれぞれ配設されており、後方への摺動時には該ストッパーリングがネジ駒と係止し、前方への摺動時にはストッパーがネジ駒と係止することで、過剰な軸筒の回転による両者の噛合の解離を防止している。
ところで、この棒状化粧料容器におけるストッパーリングは、押棒とは別体である芯チャック部の外周に周設される係止溝内にＯリングを保持することにより構成されてなるものであるが、該係止溝内に保持されるＯリングは弾性体であって容易に変形しうるので、棒状化粧料の出没操作時に押棒の表面との摩擦により捩れやすく、また互いに噛合するネジ駒と押棒との間に噛み込まれやすいものである。そのため一旦該Ｏリングが変形又はネジ駒と押棒との間に噛み込まれてしまうと、両者の噛合が阻害され、軸筒による棒状化粧料の出没操作を行えなくなる恐れがある。またＯリング自体は芯チャック部とは別体であるので部品点数が増加するとともに、製造工程が複雑となって作業性が低下してしまうので、棒状化粧料容器の製造コストの上昇を招来するものである。 By the way, in the bar-shaped cosmetic container, when the bar-shaped cosmetic is moved in and out, the shaft is excessively rotated so that the push bar slides too much in the front-rear direction, and the engagement between the push bar and the screw piece is dissociated. A stopper ring is provided on the outer peripheral surface of the core chuck unit integrated with the push rod, and a stopper is provided on the rear end edge of the push rod. The stopper ring locks with the screw piece when sliding to the front, and the stopper locks with the screw piece when sliding forward to prevent disengagement of the two due to excessive rotation of the shaft cylinder. .
By the way, the stopper ring in this bar-shaped cosmetic container is configured by holding an O-ring in a locking groove provided around the outer periphery of the core chuck part which is a separate body from the push bar. Since the O-ring held in the locking groove is an elastic body and can be easily deformed, it is easy to twist due to friction with the surface of the push bar when the stick-shaped cosmetic is moved in and out, and the screw piece and the push bar that mesh with each other. It is easy to be bitten between. For this reason, once the O-ring is deformed or is bitten between the screw piece and the push rod, the engagement between the O-ring is hindered, and there is a possibility that the bar cosmetics cannot be moved in and out by the shaft tube. Further, since the O-ring itself is separate from the core chuck portion, the number of parts increases, and the manufacturing process becomes complicated and the workability is lowered, leading to an increase in the manufacturing cost of the bar-shaped cosmetic container. Is.

しかし何より、ストッパーリングやストッパーによって、過剰な軸筒の回転による押棒とネジ駒との噛合の解離を防止しようとしていることから、該ストッパーリング等によって押棒の前後方向への摺動が停止させられた際に、軸筒を回転させている使用者がその手応えを感じてそれ以上の軸筒の回転操作を控えればよいが、手応えを感じないあるいは手応えを感じてもあえて過剰に軸筒を回転させると、その棒状化粧料容器の出没機構そのものが損壊されるおそれがあった。
特開平９−２７６０４１号 But above all, the stopper ring or stopper tries to prevent the disengagement of the push rod and screw piece due to excessive rotation of the shaft cylinder, so that the slide of the push rod in the front-rear direction is stopped by the stopper ring or the like. If the user who is rotating the shaft feels the response and refrains from further rotation of the shaft, the shaft can be overloaded. When it is rotated, there is a possibility that the appearance mechanism itself of the stick-shaped cosmetic container itself is damaged.
JP-A-9-276041

解決しようとする問題点は、簡単な構造として、棒状化粧料の出没操作時に軸筒を過剰に回転させることがあっても出没機構を損壊することがなく、逆に、ネジ駒と押棒との噛合が一旦解離しても、迅速且つ確実に、しかも容易に両者の噛合を回復させるとともに、その製造コストの低減を図ることである。   The problem to be solved is that, as a simple structure, even if the shaft tube is rotated excessively during the operation of intruding the bar-shaped cosmetic, the intrusion mechanism is not damaged. Even if the meshing is once dissociated, both the meshing can be quickly and surely and easily recovered, and the manufacturing cost can be reduced.

そこで、相互に個別回転可能に一体となる先筒と軸筒とからなる容器本体と、該容器本体内において先筒の開口部より棒状化粧料を出没させてなるネジ駒及びチャック軸とから構成され、
該先筒は、内周面前後方向に案内溝を有し、
該軸筒は、その内周面にチャック軸の雄ネジ部と噛合する雌ネジ部が螺設されるネジ駒を一体に固持し、
該チャック軸は、チャック部、雄ネジ部、及びそれらの間に一体に形成されるバネ部からなり、該チャック部は、その前端縁において棒状化粧料を把持するとともに、その側面に、前記先筒の内周面に設けられた案内溝に遊嵌する突条縁が設けられ、更に、その後端縁には径外方向に突出する鍔部が周設され、該雄ネジ部は、前記ネジ駒の雌ネジ部と噛合し、該バネ部は、上記チャック部と雄ネジ部との間において、該容器本体前後方向に伸縮自在に形成され、
軸筒と同期するネジ駒の回転並びに突条縁の案内溝への遊嵌による、チャック部の容器本体内での前後方向の摺動を、該容器本体内の前後に設けられた２個のストッパーに対するチャック部の鍔部の係止によって規制するとともに、その摺動可能距離よりも、前記雄ネジ部の最先端ネジ山と最後端ネジ山との距離を若干長く設定することにより、
軸筒の過剰回転操作によって、ネジ駒の雌ネジ部とチャック軸の雄ネジ部との噛合が解離することがあっても、前記バネ部の弾撥力によって、両ネジ部が再噛合するものである。 Therefore, a container main body composed of a front tube and a shaft tube which are integrally rotatable with each other, a screw piece and a chuck shaft in which a bar-shaped cosmetic material is projected and retracted from the opening of the front tube in the container main body. And
The leading tube has a guide groove in the longitudinal direction of the inner peripheral surface,
The shaft tube integrally holds a screw piece having a female screw portion that meshes with a male screw portion of the chuck shaft on its inner peripheral surface,
The chuck shaft includes a chuck portion, a male screw portion, and a spring portion integrally formed therebetween, and the chuck portion grips a bar-shaped cosmetic material at a front end edge thereof, A protruding edge that is loosely fitted in a guide groove provided on the inner peripheral surface of the cylinder is provided, and a flange that protrudes radially outward is provided around the rear end edge. Meshing with the female screw portion of the piece, the spring portion is formed between the chuck portion and the male screw portion so as to be extendable in the longitudinal direction of the container body,
Two stoppers provided on the front and rear sides of the container main body for sliding the chuck part in the front-rear direction in the container main body by rotating the screw piece synchronized with the shaft tube and loosely fitting the protrusions into the guide grooves. By restricting the hook portion of the chuck portion against the restriction, and by setting the distance between the most distal thread and the rearmost thread of the male screw portion slightly longer than the slidable distance,
Even if the internal thread part of the screw piece and the male thread part of the chuck shaft are disengaged due to the excessive rotation operation of the shaft cylinder, both screw parts are re-engaged by the elastic force of the spring part. is there.

そのため、使用者が棒状化粧料を容器本体の先筒の開口部より突出させる方向へ軸筒を回転させた場合、チャック部の鍔部が容器本体内の前方のストッパーと係止するに至ると、チャック部はそれ以上前進できず、棒状化粧料がそれ以上容器本体より突出することはなくなる。ところが、不注意等によりさらに軸筒を同方向へ回転させてしまうと、チャック部の前後方向への摺動可能距離よりも、雄ネジ部の最先端ネジ山と最後端ネジ山との距離の方が若干長いことから、チャック軸のバネ部を圧縮しつつ、チャック軸の雄ネジ部が前進し、チャック軸の雄ネジ部とネジ駒の雌ネジ部との噛合が解離する。しかし、次の瞬間、圧縮されたバネ部の弾撥力によりチャック軸の雄ネジ部は容器本体後端側に押し戻され、ネジ駒の雌ネジ部とチャック軸の雄ネジ部とは再噛合する。この再噛合に際してクリック音が発生することから、使用者に対する過剰回転であることの警告となる。又、仮に同方向への軸筒の回転が繰り返されても、チャック軸の雄ネジ部の前進、同雄ネジ部とネジ駒の雌ネジ部の噛合の解離及び、両者の再噛合が繰り返されるだけで、ネジ駒及びチャック軸からなる棒状化粧料の出没機構自体に対して余分な負荷がかかることはなく、該出没機構の損壊を防止できるものである。   Therefore, when the user rotates the shaft tube in a direction in which the stick-shaped cosmetic is protruded from the opening of the front tube of the container body, the collar portion of the chuck portion is locked with the front stopper in the container body. The chuck portion cannot advance any further, and the stick-shaped cosmetic material does not protrude from the container body any more. However, if the shaft cylinder is further rotated in the same direction due to carelessness, etc., the distance between the leading edge thread of the male thread and the rearmost thread will be greater than the slidable distance in the longitudinal direction of the chuck. Since the length is slightly longer, the male screw portion of the chuck shaft advances while compressing the spring portion of the chuck shaft, and the engagement between the male screw portion of the chuck shaft and the female screw portion of the screw piece is dissociated. However, at the next moment, the male screw portion of the chuck shaft is pushed back to the rear end side of the container body by the elastic force of the compressed spring portion, and the female screw portion of the screw piece and the male screw portion of the chuck shaft are reengaged. Since a click sound is generated at the time of re-engagement, it is a warning that the user is over-rotating. Even if the rotation of the shaft cylinder in the same direction is repeated, the advancement of the male screw portion of the chuck shaft, the disengagement of the engagement between the male screw portion and the female screw portion of the screw piece, and the re-engagement of both are repeated. Thus, an extra load is not applied to the bar-shaped cosmetic in / out mechanism itself composed of the screw piece and the chuck shaft, and damage to the in / out mechanism can be prevented.

また、使用者が棒状化粧料を容器本体の先筒の開口部内に没入させるため軸筒を逆に回転させた場合、チャック部の鍔部が容器本体内の後方のストッパーと係止するに至ると、チャック部はそれ以上後退できず、棒状化粧料がそれ以上容器本体内に後退することはなくなる。ところが、不注意等によりさらに軸筒を同方向へ回転させてしまうと、チャック部の前後方向への摺動可能距離よりも、雄ネジ部の最先端ネジ山と最後端ネジ山との距離の方が若干長いことから、チャック軸のバネ部を引張しつつ、チャック軸の雄ネジ部が後退し、チャック軸の雄ネジ部とネジ駒の雌ネジ部との噛合が解離する。しかし、次の瞬間、引張されたバネ部の弾撥力によりチャック軸の雄ネジ部は容器本体前端側に引き戻され、ネジ駒の雌ネジ部とチャック軸の雄ネジ部とは再噛合する。この再噛合に際してクリック音が発せられることや、出没機構自体の損壊を防止できることは、前述の場合と同様である。   Further, when the user rotates the shaft cylinder in reverse to immerse the rod-shaped cosmetic into the opening of the front tube of the container main body, the collar portion of the chuck portion is locked with the rear stopper in the container main body. Then, the chuck portion cannot be further retracted, and the stick-shaped cosmetic material is not further retracted into the container body. However, if the shaft cylinder is further rotated in the same direction due to carelessness, etc., the distance between the leading edge thread of the male thread and the rearmost thread will be greater than the slidable distance in the longitudinal direction of the chuck. Since the length is slightly longer, the male screw portion of the chuck shaft is retracted while pulling the spring portion of the chuck shaft, and the engagement between the male screw portion of the chuck shaft and the female screw portion of the screw piece is dissociated. However, at the next moment, the male screw portion of the chuck shaft is pulled back to the front end side of the container body by the elastic force of the tensioned spring portion, and the female screw portion of the screw piece and the male screw portion of the chuck shaft are reengaged. As in the case described above, a clicking sound is generated at the time of re-engagement and damage to the retracting mechanism itself can be prevented.

本願発明は、簡単な構造により、棒状化粧料の出没操作時において軸筒を過剰に回転させることがあっても、その過剰な軸筒の回転によって軸筒に固持されるネジ駒の雌ネジ部と棒状化粧料を保持するチャック軸の雄ネジ部との螺合を一旦解離させた上、両者の噛合を迅速且つ確実に、しかも容易に復活させることで、ネジ駒とチャック軸からなる出没機構の損壊を防止して継続して当該棒状化粧料容器を使用しうるようにするとともに、部品点数の削減及び製造作業の簡易化により製造コストの抑制を図ることができる優れた効果を有する。   The present invention has a simple structure, and even if the shaft tube is excessively rotated at the time of the appearance operation of the bar-shaped cosmetic, the female screw portion of the screw piece fixed to the shaft tube by the excessive rotation of the shaft tube Once the threaded engagement with the male threaded portion of the chuck shaft holding the bar-shaped cosmetic is once dissociated, the meshing of both can be quickly, reliably and easily revived so that While preventing the breakage and making it possible to continuously use the stick-shaped cosmetic container, it has an excellent effect of reducing the manufacturing cost by reducing the number of parts and simplifying the manufacturing work.

図１乃至図４に示す１は、本願発明の実施例における棒状化粧料容器であり、先端に開口部４を有する先筒３、該先筒３に対して回転自在に取り付けられる軸筒１２とからなる容器本体２内には、先筒３の開口部４より棒状化粧料２８を出没させてなるチャック軸１９と、軸筒１２内周面に一体に固持され、該チャック軸１９を構成する雄ネジ部２５と螺合するネジ駒１４とが内挿されている。（なお、本明細書においては、容器本体２の先筒３の開口部４方向を前もしくは先、軸筒１２の方向を後として方向を指示する。）   1 to 4 is a stick-shaped cosmetic container according to an embodiment of the present invention, a front tube 3 having an opening 4 at the tip, and a shaft tube 12 rotatably attached to the front tube 3. In the container body 2, the chuck shaft 19 in which the bar-shaped cosmetic 28 is projected and retracted from the opening 4 of the front tube 3 and the inner peripheral surface of the shaft tube 12 are integrally fixed to constitute the chuck shaft 19. A screw piece 14 to be screwed with the male screw portion 25 is inserted. (In the present specification, the direction is indicated with the direction of the opening 4 of the front tube 3 of the container body 2 as the front or the front and the direction of the shaft tube 12 as the rear.)

該先筒３は、外周面に段部となる係止縁５を周設すると共に、その後方には、軸筒１２（後述する。）の内周面に周設する係止凹縁１３と嵌合して、離脱不能であって且つ相互に個別回転可能となる回転嵌合部２９を形成する係止凸縁６が円周方向に周設されている。また該先筒３の内部には、先筒３の開口部４よりチャック部２０に保持する棒状化粧料２８を出没させてなるチャック軸１９（後述する。）が内挿される摺動孔７が前後方向に穿設されている。そして該摺動孔７の前方側は、チャック軸１９のチャック部２０の外径と略同一の内径を有する小径部８に、又、後方側はチャック軸１９に周設される第１鍔部２３及び第２鍔部２４の外径と略同一の内径を有する大径部９となっている。さらに該小径部８と大径部９との境界においては段部１０が形成されている。その上、先筒３の摺動孔７の小径部８の内周面には、チャック軸１９（後述する。）のチャック部２０の外周面に互いに対向するように配設された４本の突条縁２１が遊嵌し、該チャック部２０を容器本体２前後方向に案内してなる案内溝１１が形成されている。   The front tube 3 has a locking edge 5 that is a stepped portion on the outer peripheral surface, and a locking concave edge 13 that is provided on the inner peripheral surface of the shaft tube 12 (described later) on the rear side. Locking convex edges 6 that form a rotation fitting portion 29 that can be fitted and cannot be separated and can be individually rotated are circumferentially provided. Further, inside the front tube 3, there is a slide hole 7 into which a chuck shaft 19 (described later) into which a bar-shaped cosmetic material 28 held in the chuck unit 20 is projected and retracted from the opening 4 of the front tube 3 is inserted. It is drilled in the front-rear direction. The front side of the sliding hole 7 is a small diameter portion 8 having an inner diameter substantially the same as the outer diameter of the chuck portion 20 of the chuck shaft 19, and the rear side is a first flange portion provided around the chuck shaft 19. The large-diameter portion 9 has an inner diameter substantially the same as the outer diameter of the second flange portion 23 and the second flange portion 24. Further, a step portion 10 is formed at the boundary between the small diameter portion 8 and the large diameter portion 9. In addition, four inner circumferential surfaces of the small diameter portion 8 of the sliding hole 7 of the front tube 3 are arranged so as to face the outer circumferential surface of the chuck portion 20 of the chuck shaft 19 (described later). The protrusion edge 21 is loosely fitted, and a guide groove 11 formed by guiding the chuck portion 20 in the front-rear direction of the container body 2 is formed.

該軸筒１２は、一端を封止した円筒形状であって、その内周面の前端縁近傍では、先筒３の外周面の係止凸縁６と嵌合して、離脱不能であって且つ相互に個別回転可能となる回転嵌合部２９を形成する係止凹縁１３が円周方向に周設されている。また軸筒１２の内周面の略中央には、チャック軸１９（後述する。）の雄ネジ部２５と噛合する、前方へ向かって左螺旋状の雌ネジ部１５がその内周面に螺設されるネジ駒１４が一体に固持されている。なお、該ネジ駒１４は中空の円筒状であり、その内周の後端側略半分にだけ前述の雌ネジ部１５が螺設されているものである。そして、その前端縁１６が先筒３の後端縁に当接するとともに、該先筒３に設けられた摺動孔７の径大部よりも僅かに径内方向に突出するように設定されている。このように、ネジ駒１４の内周面に螺設される雌ネジ部１５の長さは、チャック軸１９の雄ネジ部２５の長さに比して著しく短く、またチャック軸１９の雄ネジ部２５が最大限摺動した際には、ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５との噛合が解離しうるようになっている。なお、ネジ駒１４の雌ネジ部１５における両端の歯部１７の厚さは、それ以外の歯部１７と比べて薄くなっている。   The shaft cylinder 12 has a cylindrical shape with one end sealed, and in the vicinity of the front end edge of the inner peripheral surface thereof, the shaft cylinder 12 is fitted with the locking convex edge 6 of the outer peripheral surface of the front tube 3 and cannot be detached. In addition, a locking concave edge 13 forming a rotation fitting portion 29 that can be individually rotated with each other is provided in the circumferential direction. Further, at the approximate center of the inner peripheral surface of the shaft cylinder 12, a female screw portion 15 having a left-hand spiral shape that meshes with a male screw portion 25 of a chuck shaft 19 (described later) is threaded on the inner peripheral surface. The provided screw piece 14 is fixed integrally. The screw piece 14 has a hollow cylindrical shape, and the above-described female screw portion 15 is screwed only in a substantially half of the rear end side of the inner periphery thereof. The front end edge 16 abuts on the rear end edge of the front tube 3 and is set so as to protrude slightly radially inward from the large diameter portion of the sliding hole 7 provided in the front tube 3. Yes. As described above, the length of the female screw portion 15 screwed to the inner peripheral surface of the screw piece 14 is remarkably shorter than the length of the male screw portion 25 of the chuck shaft 19, and the male screw of the chuck shaft 19. When the portion 25 slides to the maximum extent, the engagement between the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19 can be dissociated. Note that the thickness of the tooth portions 17 at both ends of the female screw portion 15 of the screw piece 14 is smaller than that of the other tooth portions 17.

以上より、前記容器本体２をなす先筒３と軸筒１２とは、先筒３の外周面に段部となる係止縁５に対して軸筒１２の前端縁１８を係止するとともに、先筒３の外周面の係止凸縁６と軸筒１２の内周面の係止凹縁１３とを嵌合させることで、離脱不能であって且つ相互に個別回転可能となる回転嵌合部２９を形成して一体となるものである。   As described above, the front tube 3 and the shaft tube 12 forming the container body 2 lock the front end edge 18 of the shaft tube 12 with respect to the locking edge 5 that is a stepped portion on the outer peripheral surface of the front tube 3. Rotation fitting that cannot be detached and can be individually rotated by engaging the engaging convex edge 6 on the outer peripheral surface of the front tube 3 and the engaging concave edge 13 on the inner peripheral surface of the shaft tube 12. The part 29 is formed and integrated.

一方、チャック軸１９は、棒状化粧料２８を把持してなるチャック部２０、軸筒１２の内周面に固持されるネジ駒１４の雌ネジ部１５と噛合する雄ネジ部２５、及びそれらの間に一体に形成されるバネ部２７が直列状になって構成されるものである。
そして、該チャック部２０は、外周面に互いに対向するように４本の突条縁２１が配設され、その前端縁近傍には棒状化粧料２８を把持する把持孔２２が穿設されている。この４本の突条縁２１は、先筒３の摺動孔７の小径部８の内周面に設けられた案内溝１１に遊嵌され、ネジ駒１４の回転に伴うチャック軸１９の供回りを防止している。一方、チャック部２０の後端には、径外方向に突出するものであって、チャック軸１９の前進時には摺動孔７内に設けられた段部１０と当接して係止する第１鍔部２３が前側に、又、チャック軸１９の後退時にはネジ駒１４の前端縁１６と当接して係止する第２鍔部２４が後ろ側に、それぞれ形成されている。すなわち、第１鍔部２３を係止する段部１０は前方のストッパーとして、又、同じく第２鍔部２４を係止するネジ駒１４の前端縁１６は後方のストッパーとなっている。更に、第１鍔部２３と第２鍔部２４の２個の鍔部を形成することにより、チャック部２０の前後方向への摺動可能距離を規制する際、鍔部の厚みではなく、その両鍔部２３，２４の設置距離を調整することにより、その摺動可能距離を調整することができる。
また該雄ネジ部２５は、軸筒１２の内周面に固持されるネジ駒１４の内周面に螺設される雌ネジ部１５と噛合できるように前方へ向かって左螺旋状であって、その最先端のネジ山と最後端のネジ山との間隔は、先筒３と軸筒１２とを一体として、先筒３内の段部１０と軸筒１２内に固持されたネジ駒１４の前端縁１６との距離から、第１鍔部２３と第２鍔部２４との距離を減じた距離（例えば、約２４ｍｍ）よりも若干長め（例えば、約０．５ｍｍ）となっている。すなわち、チャック部２０は、ストッパーとなる段部１０と第１鍔部２３との係止位置と、同じくストッパーとなるネジ駒１４の前端縁１６と第２鍔部２４との係止位置との間のみを前後に摺動することから、雄ネジ部２５の最先端と最後端の各ネジ山間の距離はそのチャック部２０の摺動可能距離（例えば約２４ｍｍ）よりも若干長く（例えば約０．５ｍｍ）設定されていることとなる。なお、雄ネジ部２５の両端の歯部２６は、ネジ駒１４の雌ネジ部１５と同様に、それ以外の部分に比べて薄歯となっている。
更に該バネ部２７は、上記チャック部２０と雄ネジ部２５との間に、容器本体前後方向に曲折して蛇腹状に形成され、該容器本体前後方向に伸縮自在となるものである。 On the other hand, the chuck shaft 19 includes a chuck portion 20 that grips the bar-shaped cosmetic 28, a male screw portion 25 that meshes with the female screw portion 15 of the screw piece 14 that is fixed to the inner peripheral surface of the shaft cylinder 12, and those The spring part 27 integrally formed therebetween is configured in series.
The chuck portion 20 is provided with four protruding rims 21 so as to face each other on the outer peripheral surface, and a gripping hole 22 for gripping the bar-shaped cosmetic material 28 is formed in the vicinity of the front end edge. . The four protruding rims 21 are loosely fitted in the guide grooves 11 provided on the inner peripheral surface of the small diameter portion 8 of the sliding hole 7 of the front tube 3, and the chuck shaft 19 is provided along with the rotation of the screw piece 14. Prevents turning around. On the other hand, the rear end of the chuck portion 20 protrudes outward in the radial direction. When the chuck shaft 19 moves forward, the first hook is brought into contact with and locked to the step portion 10 provided in the slide hole 7. A second collar 24 is formed on the front side, and on the rear side, when the chuck shaft 19 is retracted, the second flange 24 is brought into contact with the front end edge 16 of the screw piece 14 and locked. That is, the step portion 10 that locks the first flange portion 23 serves as a front stopper, and the front edge 16 of the screw piece 14 that similarly locks the second flange portion 24 serves as a rear stopper. Furthermore, when the slidable distance in the front-rear direction of the chuck portion 20 is restricted by forming the two flange portions of the first flange portion 23 and the second flange portion 24, not the thickness of the flange portion, The slidable distance can be adjusted by adjusting the installation distance between the two flange portions 23 and 24.
Further, the male screw portion 25 has a left spiral shape toward the front so as to be able to mesh with a female screw portion 15 screwed on the inner peripheral surface of the screw piece 14 fixed to the inner peripheral surface of the shaft cylinder 12. The distance between the most advanced thread and the last thread is such that the tip tube 3 and the shaft tube 12 are integrated, and the stepped portion 10 in the tip tube 3 and the screw piece 14 held in the shaft tube 12 are fixed. It is slightly longer (for example, about 0.5 mm) than the distance (for example, about 24 mm) obtained by subtracting the distance between the first flange portion 23 and the second flange portion 24 from the distance to the front edge 16. That is, the chuck portion 20 includes a locking position between the step portion 10 serving as a stopper and the first flange portion 23, and a locking position between the front end edge 16 of the screw piece 14 also serving as a stopper and the second flange portion 24. The distance between the leading edge of the male screw portion 25 and the rearmost screw thread is slightly longer than the slidable distance (for example, about 24 mm) of the chuck portion 20 (for example, about 0). .5 mm) is set. In addition, the tooth part 26 of the both ends of the external thread part 25 has a thin tooth | gear compared with the other part similarly to the internal thread part 15 of the screw piece 14. As shown in FIG.
Further, the spring portion 27 is bent in the front-rear direction of the container main body between the chuck portion 20 and the male screw portion 25, and is formed in a bellows shape so that it can expand and contract in the front-rear direction of the container main body.

チャック軸１９は以上のように構成されるので、使用者が容器本体２の先筒３の開口部４より棒状化粧料２８を出没させるために行う軸筒１２の回転操作において、軸筒１２を過剰に回転させることで次のように機能するものである。
即ち、使用者は棒状化粧料２８を容器本体２の先筒３の開口部４より突出させるために、軸筒１２を右回転させるが、軸筒１２を右回転し続けると、チャック軸１９の第１鍔部２３が先筒３内の摺動孔７に設けられた段部１０に突き当り、チャック部２０はそれ以上前進できなくなる。その際、使用者が不注意などにより更に軸筒１２を右回転させてしまうと、後述するようにバネ部２７が圧縮されることにより、前記ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５との噛合が解離することとなる。すなわち、前述したようにチャック軸１９の雄ネジ部２５の最先端と最後端の各ネジ山間の距離が、先筒３内の段部１０と軸筒１２内に固持されたネジ駒１４の前端縁１６との距離から第１鍔部２３と第２鍔部２４との距離を減じた距離、すなわち、ストッパーとなる段部１０とネジ駒１４の前端縁１６にそれぞれ係止する第１鍔部２３及び第２鍔部２４により、前後方向への摺動を規制されるチャック部２０の摺動可能距離よりも若干長めに設定されていることから、軸筒１２の更なる右回転、すなわちネジ駒１４の更なる右回転により、チャック軸１９は更に前進しようとする。ところが、チャック軸１９の第１鍔部２３が先筒３内の摺動孔７内に形成される段部１０と当接して係止されているので、チャック軸１９全体としては前進できないこととなる。そのため、結果的にチャック軸１９のバネ部２７を圧縮しつつ、チャック軸１９の雄ネジ部２５だけが前進し、ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５との噛合が一旦解離することとなる。しかし、次の瞬間、圧縮されたバネ部２７の弾撥力によりチャック軸１９の雄ネジ部２５は容器本体２後端側に押し戻され、ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５とは再び噛合することとなる。その際、ネジ駒１４の雌ネジ部１５及びチャック軸１９の雄ネジ部２５の両端の歯部１７、２６は薄歯となっているので、再噛合後の回転始動が円滑となる。 Since the chuck shaft 19 is configured as described above, in the rotation operation of the shaft tube 12 performed by the user to make the rod-shaped cosmetic 28 appear and disappear from the opening 4 of the front tube 3 of the container body 2, the shaft tube 12 is moved. It functions as follows by rotating it excessively.
That is, the user rotates the shaft cylinder 12 in the right direction so that the stick-shaped cosmetic 28 protrudes from the opening 4 of the front tube 3 of the container body 2. The first flange 23 hits the stepped portion 10 provided in the sliding hole 7 in the front tube 3, and the chuck portion 20 cannot advance any further. At this time, if the user further rotates the shaft cylinder 12 to the right due to carelessness or the like, the spring portion 27 is compressed as will be described later, whereby the female screw portion 15 of the screw piece 14 and the chuck shaft 19 are compressed. The engagement with the male screw portion 25 is dissociated. That is, as described above, the distance between the leading end and the rearmost thread of the male threaded portion 25 of the chuck shaft 19 is such that the front end of the screw piece 14 held in the stepped portion 10 in the front tube 3 and the shaft tube 12 is secured. The distance obtained by subtracting the distance between the first collar 23 and the second collar 24 from the distance from the edge 16, that is, the first collar engaged with the step 10 serving as a stopper and the front edge 16 of the screw piece 14 respectively. 23 and the second flange 24 are set to be slightly longer than the slidable distance of the chuck portion 20 that is restricted from sliding in the front-rear direction. By further clockwise rotation of the piece 14, the chuck shaft 19 tries to advance further. However, since the first flange portion 23 of the chuck shaft 19 is in contact with and locked with the step portion 10 formed in the sliding hole 7 in the front tube 3, the chuck shaft 19 as a whole cannot advance. Become. Therefore, as a result, while compressing the spring portion 27 of the chuck shaft 19, only the male screw portion 25 of the chuck shaft 19 moves forward, and the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19 are engaged. Will once dissociate. However, at the next moment, the male threaded portion 25 of the chuck shaft 19 is pushed back to the rear end side of the container body 2 by the elastic force of the compressed spring portion 27, and the female threaded portion 15 of the screw piece 14 and the male threaded portion of the chuck shaft 19. It will mesh with the screw portion 25 again. At that time, since the tooth portions 17 and 26 at both ends of the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19 are thin teeth, the rotation start after re-meshing becomes smooth.

一方、使用者が棒状化粧料２８を容器本体２の先筒３の開口部４より没入させるために軸筒１２を左回転させた場合、軸筒１２を左回転し続けると、チャック軸１９の第２鍔部２４が軸筒１２内に固持されるネジ駒１４の前端縁１６に突き当り、チャック部２０はそれ以上後退できなくなる。その際、使用者が不注意などにより更に軸筒１２を左回転させてしまうと、後述するようにバネ部２７が引張されることにより、前記ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５との噛合が解離することとなる。すなわち、前述したように、チャック軸１９の雄ネジ部２５の最先端と最後端の各ネジ山間の距離が、先筒３内の段部１０と軸筒１２内に固持されたネジ駒１４の前端縁１６との距離から第１鍔部２３と第２鍔部２４との距離を減じた距離よりも若干長めに設定されていることから、軸筒１２の更なる左回転、すなわちネジ駒１４の更なる左回転により、チャック軸１９は更に後退しようとする。ところが、チャック軸１９の第２鍔部２４がネジ駒１４の前端縁１６に当接して係止されているので、チャック軸１９全体としては後退できないこととなる。そのため、結果的にチャック軸１９のバネ部２７が引張され、チャック軸１９の雄ネジ部２５だけが後退し、ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５との噛合が一旦解離することとなる。しかし次の瞬間、引張されたバネ部２７の収縮力によりチャック軸１９の雄ネジ部２５は容器本体２前端側に引き戻され、ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５とは再び噛合することとなる。その際、ネジ駒１４の雌ネジ部１５及びチャック軸１９の雄ネジ部２５の両端の歯部１７、２６が薄歯となっているので、再噛合後の回転始動が円滑となる。   On the other hand, when the user rotates the shaft cylinder 12 counterclockwise in order to immerse the rod-shaped cosmetic 28 from the opening 4 of the tip cylinder 3 of the container body 2, if the shaft cylinder 12 continues to rotate counterclockwise, the chuck shaft 19 The second flange 24 hits the front end edge 16 of the screw piece 14 held in the shaft cylinder 12, and the chuck portion 20 can no longer be retracted. At this time, if the user further rotates the shaft cylinder 12 counterclockwise due to carelessness or the like, the spring portion 27 is pulled as will be described later, whereby the female screw portion 15 of the screw piece 14 and the chuck shaft 19 are pulled. The engagement with the male screw portion 25 is dissociated. That is, as described above, the distance between the leading end of the male threaded portion 25 of the chuck shaft 19 and the thread at the rearmost end is such that the stepped portion 10 in the front tube 3 and the screw piece 14 held in the shaft tube 12 are fixed. Since it is set slightly longer than the distance obtained by subtracting the distance between the first flange portion 23 and the second flange portion 24 from the distance from the front edge 16, the shaft cylinder 12 is further rotated counterclockwise, that is, the screw piece 14. Due to the further left rotation of the chuck shaft 19, the chuck shaft 19 tries to move backward further. However, since the second flange 24 of the chuck shaft 19 is in contact with and locked to the front end edge 16 of the screw piece 14, the chuck shaft 19 as a whole cannot be retracted. Therefore, as a result, the spring portion 27 of the chuck shaft 19 is pulled, only the male screw portion 25 of the chuck shaft 19 is retracted, and the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19 are engaged. Once dissociated. However, at the next moment, the male screw portion 25 of the chuck shaft 19 is pulled back to the front end side of the container body 2 by the contraction force of the tensioned spring portion 27, and the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19. Will mesh again. At that time, since the tooth portions 17 and 26 at both ends of the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19 are thin teeth, the rotation start after re-meshing becomes smooth.

以上より、図３に示すように、本願発明の実施例である棒状化粧料容器１を構成する先筒３と軸筒１２からなる容器本体２とチャック軸１９とは次のようにして一体となる。即ち、チャック軸１９のチャック部２０が把持する棒状化粧料２８の出没に際して、チャック軸１９の前進時には第１鍔部２３が摺動孔７内の段部１０と当接し、後退時には第２鍔部２４がネジ駒１４の前端縁１６と当接してバネ部２７を伸縮自在としてなるように、チャック軸１９の雄ネジ部２５と軸筒１２に固持されるネジ駒１４の雌ネジ部１５とを噛合させた上、先筒３の係止凸縁６と軸筒１２の係止凹縁１３とにより回転嵌合部２９を形成して一体とするものである。   From the above, as shown in FIG. 3, the container body 2 and the chuck shaft 19 including the tip tube 3 and the shaft tube 12 constituting the bar-shaped cosmetic container 1 according to the embodiment of the present invention are integrated as follows. Become. That is, when the bar-shaped cosmetic material 28 gripped by the chuck portion 20 of the chuck shaft 19 moves in and out, the first flange portion 23 contacts the step portion 10 in the sliding hole 7 when the chuck shaft 19 moves forward, and the second flange when the chuck shaft 19 moves backward. The male screw portion 25 of the chuck shaft 19 and the female screw portion 15 of the screw piece 14 fixed to the shaft cylinder 12 so that the portion 24 abuts on the front end edge 16 of the screw piece 14 and the spring portion 27 can be expanded and contracted. In addition, the rotation fitting portion 29 is formed integrally with the locking convex edge 6 of the front tube 3 and the locking concave edge 13 of the shaft tube 12.

そこで、本願発明の実施例における棒状化粧料容器１は上記のように構成されるので、使用者は次のようにして棒状化粧料容器１を使用するものである。
まず、使用に際しては、容器本体２の先筒３を持って軸筒１２を右回転させると、該軸筒１２の内周面において固持されるネジ駒１４は軸筒１２と一体に共回りする。そのため、該ネジ駒１４の内側面に螺設される雌ネジ部１５と噛合する雄ネジ部２５を有するチャック軸１９は、突条縁２１が先筒３の案内溝１１に遊嵌していることから回転せず、前進する。その結果、容器本体２内でチャック軸１９のチャック部２０に保持される棒状化粧料２８は容器本体２の先筒３の開口部４より突出する。なお、この軸筒１２の回転による棒状化粧料２８の突出操作は、チャック軸１９が容器本体２の先筒３の摺動孔７内を前進して、該摺動孔７内に形成される段部１０とチャック軸１９の第１鍔部２３とが当接するまで行うことができる。 Then, since the stick-shaped cosmetic container 1 in the Example of this invention is comprised as mentioned above, a user uses the stick-shaped cosmetic container 1 as follows.
First, in use, when the shaft cylinder 12 is rotated clockwise while holding the front tube 3 of the container body 2, the screw piece 14 held on the inner peripheral surface of the shaft cylinder 12 rotates together with the shaft cylinder 12. . Therefore, the chuck shaft 19 having the male screw portion 25 that meshes with the female screw portion 15 that is screwed on the inner side surface of the screw piece 14 has a protruding edge 21 loosely fitted in the guide groove 11 of the front tube 3. Therefore, it moves forward without rotating. As a result, the rod-shaped cosmetic material 28 held by the chuck portion 20 of the chuck shaft 19 in the container body 2 protrudes from the opening 4 of the front tube 3 of the container body 2. The protruding operation of the bar-shaped cosmetic material 28 by the rotation of the shaft cylinder 12 is formed in the sliding hole 7 as the chuck shaft 19 advances in the sliding hole 7 of the front cylinder 3 of the container body 2. This can be performed until the stepped portion 10 and the first flange portion 23 of the chuck shaft 19 come into contact with each other.

そして、このように棒状化粧料２８を突出させるため軸筒１２を右回転させ続けると、最終的にチャック軸１９の第１鍔部２３と先筒３の摺動孔７内に形成される段部１０とが当接し、チャック部２０は前進できなくなる。
このような状態で使用者が不注意などにより軸筒１２を更に右回転させてしまうと、前述したように、チャック軸１９のバネ部２７を圧縮しつつ、チャック軸１９の雄ネジ部２５だけが前進し、ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５との噛合が一旦解離することとなるが、次の瞬間には該圧縮されたバネ部２７の弾撥力によりチャック軸１９の雄ネジ部２５は容器本体２後端側に押し戻され、ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５とは再噛合し、その際、クリック音を発することとなる。
使用者はこのクリック音により、それ以上の右回転が過剰であることを認識することができ、不必要な右回転を停止し、もしくは逆に軸筒１２を左回転させることとなる。 Then, if the shaft cylinder 12 is continuously rotated to the right in order to protrude the bar-shaped cosmetic material 28 in this way, the step finally formed in the first flange portion 23 of the chuck shaft 19 and the sliding hole 7 of the front tube 3 is formed. The part 10 comes into contact with the chuck part 20, and the chuck part 20 cannot move forward.
If the user rotates the shaft cylinder 12 further to the right due to carelessness in such a state, only the male screw portion 25 of the chuck shaft 19 is compressed while compressing the spring portion 27 of the chuck shaft 19 as described above. Is advanced, and the engagement between the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19 is once dissociated, but at the next moment, due to the elastic force of the compressed spring portion 27. The male screw portion 25 of the chuck shaft 19 is pushed back to the rear end side of the container body 2, and the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19 are reengaged, and at this time, a clicking sound is generated. It becomes.
With this click sound, the user can recognize that the right rotation is excessive and stops the unnecessary right rotation or conversely rotates the shaft cylinder 12 counterclockwise.

一方使用後においては、先筒３を持って軸筒１２を左回転させると、該軸筒１２の内周面において固持されるネジ駒１４も一体に共回りする。そのため、該ネジ駒１４の内側面に螺設される雌ネジ部１５と噛合する雄ネジ部２５を有するチャック軸１９は、突条縁２１が先筒３の案内溝１１に遊嵌していることから回転せず、後退する。その結果、容器本体２外に突出していた棒状化粧料２８は容器本体２の先筒３の開口部４より没入する。なお、この軸筒１２の回転による棒状化粧料２８の没入操作は、チャック軸１９が容器本体２の先筒３の摺動孔７内を後退して、該軸筒１２内に固持されるネジ駒１４の前端縁１６とチャック軸１９の第２鍔部２４とが当接するまで行うことができる。   On the other hand, after use, when the shaft cylinder 12 is rotated counterclockwise with the leading cylinder 3, the screw piece 14 held on the inner peripheral surface of the shaft cylinder 12 also rotates together. Therefore, the chuck shaft 19 having the male screw portion 25 that meshes with the female screw portion 15 that is screwed on the inner side surface of the screw piece 14 has a protruding edge 21 loosely fitted in the guide groove 11 of the front tube 3. It does n’t rotate and moves backwards. As a result, the stick-shaped cosmetic 28 protruding outside the container body 2 is immersed from the opening 4 of the front tube 3 of the container body 2. The operation of immersing the rod-shaped cosmetic material 28 by the rotation of the shaft cylinder 12 is a screw that the chuck shaft 19 moves backward in the sliding hole 7 of the front tube 3 of the container body 2 and is held in the shaft cylinder 12. This can be done until the front edge 16 of the piece 14 and the second flange 24 of the chuck shaft 19 abut.

そして、このように棒状化粧料２８を没入させるため軸筒１２を左回転させ続けると、最終的にチャック軸１９の第２鍔部２４と軸筒１２内に固持されるネジ駒１４の前端縁１６とが当接することで、チャック部２０は後退できなくなる。
このような状態で使用者が不注意などにより軸筒１２を更に左回転させてしまうと、前述したように、チャック軸１９のバネ部２７を引張しつつ、チャック軸１９の雄ネジ部２５だけが後退し、ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５との噛合が一旦解離することとなるが、次の瞬間には該引張されたバネ部２７の収縮力によりチャック軸１９の雄ネジ部２５は容器本体２前端側に引き戻され、ネジ駒１４の雌ネジ部１５とチャック軸１９の雄ネジ部２５とは再噛合し、その際、クリック音を発することとなる。
使用者はこのクリック音により、それ以上の左回転が過剰であることを認識することができ、不必要な左回転を停止し、もしくは逆に軸筒１２を右回転させることとなる。 If the shaft cylinder 12 is continuously rotated counterclockwise to immerse the rod-shaped cosmetic 28 in this way, the front end edge of the screw piece 14 that is finally held in the shaft cylinder 12 and the second collar portion 24 of the chuck shaft 19 The chuck portion 20 cannot be moved backward due to the contact with 16.
If the user rotates the shaft cylinder 12 further counterclockwise due to carelessness or the like in this state, only the male screw portion 25 of the chuck shaft 19 is pulled while pulling the spring portion 27 of the chuck shaft 19 as described above. Is retracted, and the engagement of the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19 is once dissociated, but at the next moment, the chucking force is caused by the contraction force of the tensioned spring portion 27. The male screw portion 25 of the shaft 19 is pulled back to the front end side of the container body 2, and the female screw portion 15 of the screw piece 14 and the male screw portion 25 of the chuck shaft 19 are reengaged, and at this time, a click sound is generated. .
The user can recognize that the left rotation is excessive by this click sound, and stops the unnecessary left rotation or conversely rotates the shaft cylinder 12 to the right.
