Description

【０００１】
【発明の属する技術分野】
本発明は、口紅，リップクリーム，チック等の棒状化粧料を容器から繰り出して使用する棒状化粧料容器に関するものである。
【０００２】
【従来の技術】
最近、口紅等の棒状化粧料の繰り出し容器として、その組立工程を簡素化したものが、特開平８−２７５８２２号公報に提案されている。この棒状化粧料繰り出し容器は、図７に示すように、棒状化粧料３０の下端部を保持する保持筒３１と、この保持筒３１を上下動自在に内装するガイド筒３２と、このガイド筒３２に回動自在に外嵌し内周面に浅くて細かいローレットらせん溝３３ａを刻設したスリーブ３３（図８参照）と、上記ガイド筒３２の下部を止着する外筒３４と、この外筒３４に冠着するキャップ３５とを備えており、保持筒３１の外周面に突設したら合部３１ａを、ガイド筒３２に穿設したガイド溝３２ａに挿通して横側方に突出させることにより、スリーブ３３のローレットらせん溝３３ａにら合させている。図７において、３２ｂはガイド筒３２の下部外周面に形成した複数の凹部であり、スリーブ３３の下部内周面に形成した複数の凸部３３ｂに係合している。このものを使用する場合には、スリーブ３３と外筒３４とを相対回動させることにより、外筒３４に止着したガイド筒３２とスリーブ３３とを相対回動させ、この相対回動に伴い、保持筒３１を昇降させることを行う。これにより、ガイド筒３２の上端開口部から棒状化粧料３０を繰り出したり、繰り下げたりすることができる。このものでは、組立時に、保持筒３１のら合部３１ａとスリーブ３３のローレットらせん溝３３ａとを位置合わせすることなく、保持筒３１を内装したガイド筒３２にスリーブ３３を外嵌させるだけで、上記ら合部３１ａとローレットらせん溝３３ａとをら合させることができ、組立が簡単である。
【０００３】
【発明が解決しようとする課題】
しかしながら、このものは、保持筒３１とガイド筒３２とスリーブ３３と外筒３４とを備えており、部品点数が多く、在庫管理等の管理面が煩雑になる。しかも、組立時において、保持筒３１のら合部３１ａをガイド筒３２のガイド溝３２ａに係合する際に、保持筒３１を無理に撓ませなければならず、保持筒３１，ガイド筒３２が破損しやすい。また、ガイド筒３２の凹部３２ｂにスリーブ３３の凸部３３ｂを係合させる際に、スリーブ３３を無理に撓ませなければならず、ガイド筒３２，スリーブ３３が破損しやすい。
【０００４】
本発明は、このような事情に鑑みなされたもので、部品点数が少なく、組立時に破損することのない棒状化粧料容器の提供をその目的とする。
【０００５】
【課題を解決するための手段】
上記の目的を達成するため、本発明の棒状化粧料容器は、棒状化粧料保持用の繰出筒と、この繰出筒が繰出自在に収容される内筒と、この内筒に相対回動自在に外嵌される回動操作用の外筒とを備え、上記繰出筒の周壁部分に、その下端面から延びる切欠き部を形成し、上記周壁部分の下部外周面にガイド突部を突設し、上記ガイド突部の外周面にらせん溝を刻設し、上記内筒の周壁部分に、その下端面から延びるように、上記ガイド突部が挿通状に係合して外部に突出する縦穴を左右一対に形成し、上記内筒の周壁部分の、上記左右一対の縦穴に挟まれた部分を弾性片として、この弾性片の下部外周面に突部を突設し、上記外筒の内周面に、上記ガイド突部のらせん溝にら合するらせん溝を刻設するとともに、この刻設されたらせん溝の下側に環状凹部を形成し、この環状凹部の内周面に、上下方向に延びる多数の筋状突部を外筒の周方向に等間隔をあけて突設し、上記内筒の突部の外周面を上記各筋状突部の内周面に周方向に回動自在に摺接させたという構成をとる。
【０００６】
すなわち、本発明の棒状化粧料容器は、棒状化粧料保持用の繰出筒と、この繰出筒が繰出自在に収容される内筒と、この内筒に相対回動自在に外嵌される回動操作用の外筒とを備えている。そして、上記繰出筒の周壁部分に、その下端面から延びる切欠き部を形成し、上記周壁部分の下部外周面に、外周面にらせん溝を刻設したガイド突部を突設している。また、上記内筒の周壁部分に、その下端面から延びるように、上記ガイド突部が挿通状に係合して外部に突出する縦穴を形成し、上記内筒の周壁部分の下部外周面に突部を突設している。また、上記外筒の内周面に、上記ガイド突部のらせん溝にら合するらせん溝を刻設し、上記内筒の突部に回動自在に係合する環状凹部を形成している。このものでは、外筒を内筒に対して相対回動させると、相対回動する内筒に繰出筒が連れ回りし、この連れ回りにより、繰出筒のガイド突部が外筒のらせん溝にら合しながら、このらせん溝に沿って上下移動し、繰出筒が昇降する（繰り出されたり、繰り下げられたりする）。この昇降に際し、繰出筒の周壁部分に、その下端面から延びる切欠き部を形成しているため、ガイド突部のらせん溝と内筒のらせん溝とのら合が弾圧状に行われ、上記ガイド突部の外周面と内筒の内周面の間にがたつきが生じず、スムーズに回動する。このように、本発明の棒状化粧料容器は、繰出筒と内筒と外筒とで構成されているため、部品点数が少なく、在庫管理等の管理面が簡素化するうえ、径が細くなってスリム化が可能になる。しかも、内筒の周壁部分に穿設する縦穴を利用し、これを下端面から延ばしているため、内筒の周壁部分が撓みやすくなる。また、繰出筒の周壁部分に、その下端面から延びる切欠き部を形成しているため、繰出筒の周壁部分も撓みやすくなる。したがって、組立時において、内筒を外筒に挿通する際に、内筒が撓みやすく、また、繰出筒を内筒に挿通する際に、繰出筒が撓みやすく、繰出筒，内筒や外筒が長期にわたって破損しない。
【０００７】
また、本発明では、上記内筒の突部の外周面を外筒の環状凹部の内周面に摺接させたため、内筒の外周面と外筒の内周面との間にがたつきが生じず、スムーズに回動する。
【０００８】
【発明の実施の形態】
つぎに、本発明の実施の形態を図面にもとづいて詳しく説明する。
【０００９】
【実施例】
図１は本発明の棒状化粧料容器の一実施の形態を示している。この棒状化粧料容器は、図２に示すように、棒状化粧料５が保持されるＡＢＳ樹脂（アクリロニトリルブタジエンスチレン共重合体）製の中皿（繰出筒）１と、この中皿１が繰り出し自在に収容されるＡＢＳ樹脂製のスリーブ２（内筒）と、このスリーブ２に相対回転自在に外嵌されるＡＢＳ樹脂製の袴（回動操作用の外筒）３と、この袴３に冠着されるＡＢＳ樹脂製のキャップ４と、上記袴３の下端開口部に貼着される紙製，アルミニウム製等のラベル６とからなる。
【００１０】
より詳しく説明すると、上記中皿１は円筒状に形成されており、図３に示すように、その上部に、棒状化粧料５を支受する仕切り板１２が設けられている。上記中皿１の周壁部分のうち、上記仕切り板１２より上側部分が大径に形成されているとともに、下側部分が小径に形成されており、これら両部分の間に、内・下向き傾斜面に形成された段部１ａが設けられている。上記小径周壁部分（上記仕切り板１２より下側部分）には、相対峙する位置に、一対の切欠き溝１３が上記小径周壁部分の下端面から垂直に立ち上げ形成されており、これら両切欠き溝１３で挟まれた部分が弾性片１４に形成されている。これら両弾性片１４には、その中央部分の下部外周面に、縦長形状（長方形の４隅が１／４円弧状に切欠かれている）の薄肉湾曲板体からなる一対のガイド突部１１が突設されており、これら両ガイド突部１１の表面には、後述する袴３のらせん溝１７にら合する複数本のらせん溝１０が刻設されている。このような両ガイド突部１１は、上記各弾性片１４の作用により、袴３のらせん溝１７に弾圧状にら合している。
【００１１】
上記スリーブ２は円筒状に形成されており、図４に示すように、その外周面の上側部分が大径に形成されているとともに、下側部分が小径に形成されている。また、上記スリーブ２の内周面は、その上側部分が大径に形成されているとともに、下側部分が小径に形成されており、両部分の間に、上記中皿１の段部１ａに抜け落ち防止状に係合する段部２ａが設けられている。また、上記スリーブ２の周壁部分のうち、小径周壁部分（上記段部２ａの下側部分）には、相対峙する位置に、その下端面から垂直に延びて上記段部２ａ近傍に至る一対の縦穴１５が形成されており、これら一対の縦穴１５で挟まれた部分が弾性片２１に形成されている。このような両縦穴１５には、上記ガイド突部１１が挿通状に係合し両縦穴１５の外部に突出している。また、これら両縦穴１５には、その左右両側部の外周面に、後述する袴３の環状凹凸面１８に回動自在に係合する突部１６が突設されている。これら４つの突部１６は、スリーブ２が袴３の上方に引き抜かれるのを防止している。
【００１２】
上記袴３は円筒状に形成されており、その上端面で、上記スリーブ２の外周面大径部２ｂを載置している。また、上記袴３には、図５に示すように、その内周面に、上記両ガイド突部１１のらせん溝１０にら合する多数のらせん溝１７が刻設されている。上記らせん溝１７は、３１．７５ｍｍの間に３０条の右ねじを設けたものである。このようならせん溝１７の下部に、多数の筋状突部１８ａが等間隔をあけて垂直に突設された環状凹凸面１８が形成されており、上記各筋状突部１８ａの内周面が上記スリーブ２の各突部１６の外周面に摺接している。図において、１９は上記袴３の上側小径部の外周面に突設された突部であり、後述のキャップ４の凹部２０に着脱自在に係合する。
【００１３】
上記キャップ４は、図６に示すように、有天円筒状に形成されており、上記袴３の突部１９に対応する内周面の部分に、上記袴３の突部１９に着脱自在に係合する凹部２０が形成されている。また、上記ラベル６は、円盤状に形成されており、上記袴３の下端開口部を蓋している。
【００１４】
このような棒状化粧料容器を、つぎのようにして組み立てることができる。すなわち、まず、袴３の上端開口部にスリーブ２の下端開口部を対面させた状態で袴３の上方にスリーブ２を配置し、ついで、スリーブ２を袴３側に押し込む。これにより、スリーブ２の弾性片２１が内方に撓みながらスリーブ２の各突部１６が袴３の内周面に当接して袴３内を通り、上記各突部１６が袴３の環状凹凸面１８に係合する。つぎに、スリーブ２の上方に中皿１を配置し、スリーブ２の両縦穴１５に中皿１の両ガイド突部１１を位置決めし、その状態で、中皿１をスリーブ２側に押し込む。これにより、中皿１の弾性片１４が内方に撓みながら両ガイド突部１１がスリーブ２の内周面に当接してスリーブ２内を通り、スリーブ２の縦穴１５に係合する。と同時に、両ガイド突部１１が両縦穴１５から外部に突出し、両ガイド突部１１のらせん溝１０と袴３のらせん溝１７がら合する。そののち、袴３の上側小径部にキャップ４を冠着する。このようにして組み立てたのち袴３の下端開口部にラベル６を貼着して蓋することを行う。なお、このようなラベル６の貼着は、上記組み立て作業の最初に行ってもよいし、途中に行ってもよい。
【００１５】
このようにして組み立てられた棒状化粧料容器は、袴３がスリーブ２に対して相対回動自在になっており、両者２，３を相対回動させると、スリーブ２に連れ回りする中皿１が縦穴１５内を上下移動する。これにより、中皿１がスリーブ２内を昇降する。このとき、中皿１の両ガイド突部１１が袴３のらせん溝１７に弾圧状にら合し、かつ、スリーブ２の両突部１６が袴３の環状凹凸面１８の筋状突部１８ａの内周面に摺接しているため、中皿１の両ガイド突部１１と袴３の内周面の間、およびスリーブ２の両突部１６と袴３の内周面の間に、がたつきがなくなり、スムーズに相対回動する。そして、不使用時には、中皿１を下降させ、その状態でキャップ４を袴３の上側小径部に冠着させておく。また、使用時には、キャップ４を取り外し、袴３をスリーブ２に対して相対的に回動させる。これにより、中皿１が袴３と連れ回りして上昇し、棒状化粧料５がスリーブ２の上端開口から突出して使用可能状態になる。
【００１６】
このように、上記実施の形態では、棒状化粧料容器が、中皿１とスリーブ２と袴３とキャップ４とからなるため、部品点数が少なく、在庫管理等の管理面が簡素化するうえ、外径が小さくなり、棒状化粧料容器がスリム化する。しかも、中皿１の周壁部分に形成した弾性片１４にガイド突部１１を形成し、スリーブ２の周壁部分に形成した弾性片２１に突部１６を形成しているため、組立時に、中皿１をスリーブ２に押し込み、また、スリーブ２を袴３に押し込んでも、弾性片１４，２１が撓み、中皿１，スリーブ２，袴３が損傷することがなく、また、回動時にがたつくこともない。
【００１７】
【発明の効果】
以上のように、本発明の棒状化粧料容器によれば、繰出筒と内筒と外筒とで構成されているため、部品点数が少なく、在庫管理等の管理面が簡素化するうえ、径が細くなってスリム化が可能になる。しかも、内筒の周壁部分に穿設する縦穴を利用し、これを下端面から延ばしているため、内筒の周壁部分が撓みやすくなる。また、繰出筒の周壁部分に、その下端面から延びる切欠き部を形成しているため、繰出筒の周壁部分も撓みやすくなる。したがって、組立時において、内筒を外筒に挿通する際に、内筒が撓みやすく、また、繰出筒を内筒に挿通する際に、繰出筒が撓みやすく、繰出筒，内筒や外筒が長期にわたって破損しない。また、本発明では、上記内筒の突部の外周面を外筒の環状凹部の内周面に摺接させたため、内筒の外周面と外筒の内周面との間にがたつきが生じず、スムーズに回動する。

Recently, as a feeding container for stick-shaped cosmetics such as lipstick, a simplified assembly process has been proposed in Japanese Patent Laid-Open No. 8-275822. As shown in FIG. 7, the stick-shaped cosmetic material delivery container includes a holding cylinder 31 that holds the lower end portion of the stick-shaped cosmetic material 30, a guide cylinder 32 that houses the holding cylinder 31 in a vertically movable manner, and the guide cylinder 32. And a sleeve 33 (see FIG. 8) in which a shallow and fine knurled spiral groove 33a is engraved on the inner peripheral surface, and an outer cylinder 34 for fixing the lower portion of the guide cylinder 32, and the outer cylinder. 34 and a cap 35 which is attached to the outer periphery of the holding cylinder 31. When the projection 31a is inserted into the guide groove 32a drilled in the guide cylinder 32, it protrudes laterally. The sleeve 33 is engaged with the knurled spiral groove 33a. In FIG. 7, reference numeral 32 b denotes a plurality of concave portions formed on the lower outer peripheral surface of the guide cylinder 32 and engages with a plurality of convex portions 33 b formed on the lower inner peripheral surface of the sleeve 33. When this is used, the sleeve 33 and the outer cylinder 34 are rotated relative to each other, whereby the guide cylinder 32 and the sleeve 33 fixed to the outer cylinder 34 are rotated relative to each other. Then, the holding cylinder 31 is moved up and down. Thereby, the bar-shaped cosmetic 30 can be fed out or lowered from the upper end opening of the guide tube 32. In this case, at the time of assembling, the sleeve 33 is fitted on the guide cylinder 32 in which the holding cylinder 31 is housed without aligning the joint portion 31a of the holding cylinder 31 and the knurled spiral groove 33a of the sleeve 33. The fitting portion 31a and the knurled spiral groove 33a can be joined together, and assembly is easy.
[0003]
[Problems to be solved by the invention]
However, this is provided with the holding cylinder 31, the guide cylinder 32, the sleeve 33, and the outer cylinder 34, so that the number of parts is large and the management side such as inventory management becomes complicated. In addition, when assembling the engaging portion 31a of the holding cylinder 31 with the guide groove 32a of the guide cylinder 32, the holding cylinder 31 must be bent forcibly. Easy to break. Further, when the convex portion 33b of the sleeve 33 is engaged with the concave portion 32b of the guide tube 32, the sleeve 33 must be forcibly bent, and the guide tube 32 and the sleeve 33 are easily damaged.
[0004]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a stick-shaped cosmetic container that has a small number of parts and is not damaged during assembly.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, a stick-shaped cosmetic container according to the present invention comprises a feeding cylinder for holding a stick-shaped cosmetic material, an inner cylinder in which the feeding cylinder is accommodated so as to be freely fed, and a relative rotation with respect to the inner cylinder. An outer tube for turning operation that is externally fitted, a notch extending from the lower end surface is formed in the peripheral wall portion of the feeding cylinder, and a guide protrusion is provided on the lower outer peripheral surface of the peripheral wall portion. A helical groove is formed on the outer peripheral surface of the guide protrusion, and a vertical hole is formed in the peripheral wall portion of the inner cylinder so that the guide protrusion engages in an insertion shape and protrudes to the outside so as to extend from the lower end surface thereof. A pair of left and right formed, a portion of the peripheral wall portion of the inner cylinder sandwiched between the pair of left and right vertical holes is used as an elastic piece, and a protrusion is provided on the lower outer peripheral surface of the elastic piece, and the inner periphery of the outer cylinder the surface, while engraved spiral groove et if the spiral groove of the guide protrusions, under this engraved by spiral grooves To form an annular recess, the inner peripheral surface of the annular recess, a number of streaky projections extending in the vertical direction in the circumferential direction of the outer cylinder and at equal intervals projected outer circumference of the projection of the inner cylinder A configuration is adopted in which the surface is slidably contacted with the inner peripheral surface of each of the streaky projections in the circumferential direction .
[0006]
That is, the bar-shaped cosmetic container of the present invention includes a feeding cylinder for holding a bar-shaped cosmetic, an inner cylinder in which the feeding cylinder is housed so as to be freely fed, and a rotation that is externally fitted to the inner cylinder so as to be relatively rotatable. And an outer cylinder for operation. And the notch part extended from the lower end surface is formed in the surrounding wall part of the said delivery cylinder, and the guide protrusion which cut the spiral groove in the outer peripheral surface is protrudingly provided in the lower outer peripheral surface of the said surrounding wall part. In addition, a vertical hole is formed in the peripheral wall portion of the inner cylinder so as to extend from the lower end surface of the inner cylinder so that the guide protrusion is inserted and protrudes to the outside. Protrusions are protruding. In addition, a spiral groove that engages with the spiral groove of the guide protrusion is formed on the inner peripheral surface of the outer cylinder, and an annular recess that pivotably engages with the protrusion of the inner cylinder is formed. . In this case, when the outer cylinder is rotated relative to the inner cylinder, the feeding cylinder is rotated with the relatively rotating inner cylinder, so that the guide protrusion of the feeding cylinder moves into the spiral groove of the outer cylinder. While moving up and down, it moves up and down along the spiral groove, and the feeding cylinder moves up and down (drawn and lowered). At the time of this up and down, the notch extending from the lower end surface is formed in the peripheral wall portion of the feeding cylinder, so that the helical groove of the guide protrusion and the helical groove of the inner cylinder are elastically pressed, No backlash occurs between the outer peripheral surface of the guide projection and the inner peripheral surface of the inner cylinder, and the guide projection rotates smoothly. Thus, since the stick-shaped cosmetic container of the present invention is composed of the feeding cylinder, the inner cylinder, and the outer cylinder, the number of parts is small, the management surface such as inventory management is simplified, and the diameter is reduced. And slimming becomes possible. And since the vertical hole drilled in the surrounding wall part of an inner cylinder is utilized and this is extended from the lower end surface, the surrounding wall part of an inner cylinder becomes easy to bend. Moreover, since the notch part extended from the lower end surface is formed in the surrounding wall part of a delivery cylinder, the surrounding wall part of a delivery cylinder also becomes easy to bend. Therefore, at the time of assembly, when inserting the inner cylinder into the outer cylinder, the inner cylinder is easily bent, and when inserting the feeding cylinder into the inner cylinder, the feeding cylinder is easily bent, and the feeding cylinder, the inner cylinder, and the outer cylinder. Will not break for a long time.
[0007]
Further, in the present invention, backlash between the outer peripheral surface of the projecting portion of the inner tube due to brought into sliding contact with the inner peripheral surface of the annular recess of the outer cylinder, an outer peripheral surface and the inner peripheral surface of the outer cylinder of the inner cylinder There is no sticking and it rotates smoothly.

Next, the intermediate plate 1 is disposed above the sleeve 2, the guide projections 11 of the intermediate plate 1 are positioned in the vertical holes 15 of the sleeve 2, and the intermediate plate 1 is pushed into the sleeve 2 in this state. As a result, while the elastic piece 14 of the inner tray 1 bends inward, both guide projections 11 abut against the inner peripheral surface of the sleeve 2, pass through the sleeve 2, and engage with the vertical hole 15 of the sleeve 2. At the same time, both guide protrusions 11 protrude outward from both vertical holes 15, and the spiral groove 10 of both guide protrusions 11 and the spiral groove 17 of the flange 3 are joined. After that, the cap 4 is attached to the upper small diameter portion of the heel 3. After assembling in this way, the label 6 is attached to the lower end opening of the bowl 3 and covered. In addition, such a sticking of the label 6 may be performed at the beginning of the assembly work or may be performed in the middle.
[0015]
The rod-shaped cosmetic container assembled in this way has the basket 3 rotatable relative to the sleeve 2, and when the two 2 and 3 are rotated relative to each other, the inner tray 1 that rotates with the sleeve 2. Moves up and down in the vertical hole 15. Thereby, the inner tray 1 moves up and down in the sleeve 2. At this time, both guide protrusions 11 of the inner plate 1 are elastically engaged with the spiral groove 17 of the flange 3, and both protrusions 16 of the sleeve 2 are streaky protrusions 18 a of the annular uneven surface 18 of the flange 3. Between the two guide projections 11 of the inner tray 1 and the inner peripheral surface of the flange 3, and between the both protrusions 16 of the sleeve 2 and the inner peripheral surface of the flange 3. There is no rattling and the relative rotation is smooth. Then, when not in use, the inner tray 1 is lowered, and the cap 4 is put on the upper small diameter portion of the basket 3 in this state. In use, the cap 4 is removed, and the collar 3 is rotated relative to the sleeve 2. As a result, the inner plate 1 is lifted up with the basket 3, and the bar-shaped cosmetic 5 protrudes from the upper end opening of the sleeve 2 and becomes ready for use.
[0016]
Thus, in the above embodiment, since the stick-shaped cosmetic container is composed of the inner tray 1, the sleeve 2, the basket 3, and the cap 4, the number of parts is small, and management aspects such as inventory management are simplified. The outer diameter is reduced, and the stick-shaped cosmetic container is slimmed. Moreover, since the guide protrusion 11 is formed on the elastic piece 14 formed on the peripheral wall portion of the inner tray 1 and the protrusion 16 is formed on the elastic piece 21 formed on the peripheral wall portion of the sleeve 2, Even if 1 is pushed into the sleeve 2 and the sleeve 2 is pushed into the flange 3, the elastic pieces 14 and 21 are not bent, the inner plate 1, the sleeve 2 and the flange 3 are not damaged, and may be rattled when rotating. Absent.

【The invention's effect】
As described above, according to the stick-shaped cosmetic container of the present invention, since it is composed of the feeding cylinder, the inner cylinder, and the outer cylinder, the number of parts is small, the management surface such as inventory management is simplified, and the diameter Can be made slimmer. And since the vertical hole drilled in the surrounding wall part of an inner cylinder is utilized and this is extended from the lower end surface, the surrounding wall part of an inner cylinder becomes easy to bend. Moreover, since the notch part extended from the lower end surface is formed in the surrounding wall part of a delivery cylinder, the surrounding wall part of a delivery cylinder also becomes easy to bend. Therefore, at the time of assembly, when inserting the inner cylinder into the outer cylinder, the inner cylinder is easily bent, and when inserting the feeding cylinder into the inner cylinder, the feeding cylinder is easily bent, and the feeding cylinder, the inner cylinder, and the outer cylinder. Will not break for a long time. Further, in the present invention, backlash between the outer peripheral surface of the projecting portion of the inner tube due to brought into sliding contact with the inner peripheral surface of the annular recess of the outer cylinder, an outer peripheral surface and the inner peripheral surface of the outer cylinder of the inner cylinder There is no sticking and it rotates smoothly.
