本発明は、口紅を初めとする各種棒状外用剤組成物の容器に関する。また本発明は、棒状外用剤組成物容器と棒状外用剤組成物とを備えた棒状外用剤組成物製品に関する。 TECHNICAL FIELD The present invention relates to a container for various stick-shaped external preparation compositions such as lipstick. The present invention also relates to a rod-shaped topical composition product comprising a rod-shaped topical composition container and a rod-shaped topical composition.

口紅を初めとする各種の棒状外用剤組成物の容器である棒状外用剤組成物容器として、従来、棒状外用剤組成物の下端域を保持する保持体を昇降させる昇降機構を備えた容器が知られている。また、昇降機構として、占有する空間が狭いという省スペース性に優れた２重螺旋機構が知られており、棒状外用剤組成物容器の昇降機構として２重螺旋機構が採用されることも多くなっている（特許文献１参照）。２重螺旋機構とは、昇降基部と、該昇降基部と螺合する第１昇降部と、該第１昇降部と螺合する第２昇降部とを備え、昇降基部をその軸回りに回転させることで、昇降基部の下端と第２昇降部の上端との間を拡縮可能な機構である。 Conventionally, as a stick-shaped external composition container, which is a container for various stick-shaped external composition such as lipstick, there is known a container equipped with an elevating mechanism for moving up and down a holder that holds the lower end region of the stick-shaped external composition. It is In addition, as a lifting mechanism, a double spiral mechanism is known, which is excellent in space saving in that it occupies a narrow space. (see Patent Document 1). The double helix mechanism includes an elevating base, a first elevating part screwed with the elevating base, and a second elevating part screwed with the first elevating part, and rotates the elevating base around its axis. Thus, it is a mechanism that can expand and contract between the lower end of the lifting base and the upper end of the second lifting section.

しかしながら、本発明者らは、昇降機構として２重螺旋機構を備える棒状外用剤組成物容器や棒状外用剤組成物製品は、それらを動かしたときに異音が生じる場合があること、特に棒状外用剤組成物容器や棒状外用剤組成物製品を、正立状態から倒立させたり、倒立状態から正立させたり、あるいは上下に動かしたときに、何かと何かとが擦れる際に生じるような異音が生じる場合があることを見出した。斯かる異音の発生は、棒状外用剤組成物製品の高級感を損なわせたり、消費者等に、内部の部品が破損していないにも拘わらずに破損していると誤認させる等、製品の品質や状態について誤認を与える恐れがある。 However, the present inventors have found that a rod-shaped topical composition container and a rod-shaped topical composition product having a double spiral mechanism as an elevating mechanism may generate abnormal sounds when moved. When the drug composition container or the rod-shaped topical drug composition product is turned from an upright position to an upright position, or moved up and down, there is an abnormal noise that occurs when something rubs against something. I found that there is a case. The occurrence of such abnormal noise impairs the high-class appearance of the rod-shaped external composition product, and misleads consumers, etc., that internal parts are damaged even though they are not damaged. There is a risk of giving false recognition about the quality and condition of the product.

したがって本発明の解決課題は、従来技術が有する課題を解決することにある。 Therefore, the problem to be solved by the present invention is to solve the problem of the prior art.

本発明者らは、上記異音の発生を原因及び抑制方法について鋭意研究した結果、異音の発生の原因が、２重螺旋機構において、昇降基部の下端と第２昇降部の上端との間の距離が最大の状態と該距離が最小の状態との間の中間状態において、第１昇降部が、昇降基部及び第２昇降部に対して軸回りに回転しながら移動することにあることを知見し、また第１昇降部が回転しながら移動することを抑制することで、異音の発生を抑制できることを見出した。第１昇降部の回転及び移動を抑制する方法としては、昇降機構に高粘度油やワックス等を供給することが考えられるが、その場合、昇降させる操作を軽い力でスムーズに行えないことや、昇降動作の繰り返しや長期保存の間に高粘度油やワックスが偏在することによって、異音の抑制効果が短期間しか維持されないことも見出した。
本発明は、斯かる知見に基づきなされたものである。 The inventors of the present invention conducted intensive research on the cause of the noise and how to suppress it. in an intermediate state between the state where the distance of In addition, the inventors have found that the occurrence of abnormal noise can be suppressed by suppressing the movement of the first elevating unit while rotating. As a method for suppressing the rotation and movement of the first elevating unit, it is conceivable to supply high-viscosity oil, wax, etc. to the elevating mechanism. We also found that the effect of suppressing abnormal noise is maintained only for a short period of time due to uneven distribution of high-viscosity oil and wax during repeated up-and-down operations and long-term storage.
The present invention is made based on such findings.

摩擦抵抗を高める手段は、第１突起２５ａ及び第２突起２５ｂの一方に設けられていても良く、両方に設けられていても良く、また後述する第２実施形態のように、突起間の谷底部分２５ｅ等に形成されていてもよいが、第１実施形態のように、摩擦抵抗を高める手段として、接触部位の表面に微小な凹凸を形成する場合、第１突起２５ａ及び第２突起２５ｂの両方に、摩擦抵抗を高める手段として微細な凹凸が設けられていることが好ましい。 Fine unevenness as a means for increasing frictional resistance is formed by forming fine unevenness on the surfaces of the mutually contacting portions of the mutually facing surfaces of the first threaded portion 25A or the second threaded portion 25B, so that the surfaces of the mutually contacting portions It increases the frictional resistance of
When fine unevenness is provided as a means for increasing frictional resistance, as a method for forming the fine unevenness, a member having fine unevenness such as the elevating base portion 21, the first elevating portion 22, and the second elevating portion 23 is used. In the case of resin, the inner surface of the mold for molding those parts with synthetic resin is roughened by shaving, sandblasting, etching, etc., and the mold is used. However, the method is not limited to this, and for example, the finished part may be subjected to machining such as shaving, sandblasting, or the like. Injection molding is preferred as molding.
The means for increasing the frictional resistance may be provided on one of the first protrusion 25a and the second protrusion 25b, or may be provided on both of them.

[Method for measuring arithmetic mean roughness Ra]
Arithmetic mean roughness Ra can be measured by various surface roughness measuring instruments, for example, one-shot 3D shape measuring instrument VR-5200 manufactured by Keyence Corporation. The same method can be used to measure the surface roughness of the mold and the surface roughness of the completed member.

上記の粗面加工は、接触部位の表面を荒くして接触部位に引っ掛かりを作っているため、第１昇降部２２の動作の制御を可能としながら、クリアランスを維持しているため、異音の発生を抑制しつつ、摺動性への影響が出ないようにする観点から好ましい。また、上記の粗面加工を行った金型を用いて棒状外用剤組成物容器１を成形することにより、棒状外用剤組成物容器１を大量生産した場合であっても、各棒状外用剤組成物容器１の粗面加工部位が同一の摩擦抵抗を得ることができる。 In the above-described roughening, the surface of the contact portion is roughened to create a hook in the contact portion, so that the clearance is maintained while the operation of the first elevating portion 22 can be controlled. It is preferable from the viewpoint of suppressing the occurrence and preventing the slidability from being affected. In addition, even if the rod-shaped external composition container 1 is mass-produced by molding the rod-shaped external composition container 1 using the mold having the surface roughened as described above, each rod-shaped external composition composition can be produced. The same frictional resistance can be obtained at the roughened portion of the object container 1 .

The height difference is preferably 120 μm or less, preferably 20 μm or less. Moreover, it is preferable that a large number of fine unevennesses are formed in a state in which the convex portions and the concave portions are dispersed in the plane direction.

以上の構成を有する棒状外用剤組成物容器１を用い、これに棒状外用剤組成物２を固定することで、目的とする棒状外用剤組成物製品３が得られる。この工程を図６（ａ）ないし図６（ｄ）を参照しながら説明する。まず図６（ａ）に示すとおり、本体基部４０内に、中皿１０、昇降基部２１、第１昇降部２２及び第２昇降部２３を含む昇降機構２０、並びに外筒３０を組み付ける。組み付けに際しては、予め第１昇降部２２及び第２昇降部２３を回転させて、中皿１０を繰り出した状態とする。そして、その中皿１０を繰り出した状態の昇降機構及び外筒３０を本体基部４０に組み付ける。次に、繰り出した状態の中皿１０の収容空間Ｓに、図６（ａ）及び図６（ｂ）に示すように、棒状外用剤組成物２の下端域２ａを挿入して収容させる。 By using the rod-shaped topical composition container 1 having the above configuration and fixing the rod-shaped topical composition 2 thereto, the desired rod-shaped topical composition product 3 is obtained. This process will be described with reference to FIGS. 6(a) to 6(d). First, as shown in FIG. 6( a ), the inner tray 10 , the lifting base 21 , the lifting mechanism 20 including the first lifting part 22 and the second lifting part 23 , and the outer cylinder 30 are assembled into the main body base part 40 . At the time of assembly, the first lifting section 22 and the second lifting section 23 are rotated in advance so that the inner plate 10 is drawn out. Then, the elevating mechanism and the outer cylinder 30 with the inner tray 10 drawn out are assembled to the main body base portion 40 . Next, as shown in FIGS. 6(a) and 6(b), the lower end region 2a of the rod-shaped external preparation composition 2 is inserted and accommodated in the accommodation space S of the inner plate 10 in the extended state.

棒状外用剤組成物２が中皿１０の収容空間Ｓ内に収容されたら、外筒３０を把持した状態で本体基部４０を軸周りに回転させる。これによって図６（ｃ）に示すように、繰り出し状態になっている中皿１０が次第に繰り下げられる。繰り下げられる順番としては、第１実施形態のように、第１螺合部の相対向面に摩擦抵抗を高める手段が設けられている場合、まず摩擦抵抗が相対的に低い第１昇降部２２と第２昇降部２３との螺合部である第２螺合部が繰り下がり、その後摩擦抵抗が相対的に高い昇降基部２１と第１昇降部２２との螺合部である第１螺合部が繰り下がる。
そして、この繰り下げによって、図６（ｄ）に示すように、目的とする棒状外用剤組成物製品３〔図１参照〕が得られる。 After the rod-shaped external preparation composition 2 is accommodated in the accommodation space S of the inner plate 10, the main body base 40 is rotated around the axis while the outer cylinder 30 is held. As a result, as shown in FIG. 6(c), the middle plate 10 in the extended state is gradually lowered. As for the descending order, as in the first embodiment, when means for increasing the frictional resistance is provided on the opposing surface of the first threaded portion, first the first lifting portion 22 with relatively low frictional resistance and the The second threaded portion that is the threaded portion with the second elevating portion 23 is lowered, and then the first threaded portion that is the threaded portion between the elevating base portion 21 and the first elevating portion 22 having relatively high frictional resistance. is carried forward.
Then, as shown in FIG. 6(d), the desired rod-shaped external preparation composition product 3 (see FIG. 1) is obtained by carrying down.

第１実施形態の棒状外用剤組成物容器１及び棒状外用剤組成物製品３によれば、第１螺合部２５Ａと第２螺合部２５Ｂの少なくとも一方における相対向面２５に、該相対向面２５間の摩擦抵抗を高める手段が設けられていることにより、第１昇降部２２が動くことによる異音の発生を効果的に抑制することができる。異音の発生が抑制される理由は、昇降基部２１の下端と第２昇降部２３の上端との間の距離が最大の状態と該距離が最小の状態との間の中間状態において、昇降基部２１をその軸回りに回転させないにも拘わらずに、第１昇降部２２が動くことが、特に昇降基部２１及び第２昇降部２３に対して軸回りに回転しながら移動することが抑制されるためである。
また、第１実施形態の棒状外用剤組成物容器１及び棒状外用剤組成物製品３によれば、昇降機構２０に高粘度油やワックス等を供給して異音の発生を抑制する場合とは異なり、昇降動作の繰り返しや長期保存により高粘度油やワックスが偏在することもないので、異音の発生抑制効果が長期間持続する。
また摩擦抵抗を向上させる手段として微細な凹凸を設けてあるため、昇降基部２１と第１昇降部２２との間又は第１昇降部２２と第２昇降部２３との間の摺動性が良好に維持されるため、昇降機構２０により中皿１０等の保持体や棒状外用剤組成物２を昇降させる操作を軽い力でスムーズに行うことができる操作性にも優れている。 According to the rod-shaped topical composition container 1 and the rod-shaped topical composition product 3 of the first embodiment, the mutually facing surfaces 25 of at least one of the first threaded portion 25A and the second threaded portion 25B have Since the means for increasing the frictional resistance between the surfaces 25 is provided, it is possible to effectively suppress the generation of abnormal noise due to the movement of the first elevating section 22 . The reason why the noise is suppressed is that in an intermediate state between a state where the distance between the lower end of the lift base 21 and the upper end of the second lift unit 23 is maximum and a state where the distance is minimum, the lift base 21 is not rotated about its axis, the movement of the first elevating part 22, particularly the movement of the elevating part 21 and the second elevating part 23 while rotating about its axis, is suppressed. Because.
Further, according to the rod-shaped topical composition container 1 and the rod-shaped topical composition product 3 of the first embodiment, the case where high-viscosity oil, wax, or the like is supplied to the lifting mechanism 20 to suppress the generation of abnormal noise In contrast, high-viscosity oil and wax are not unevenly distributed due to repeated up-and-down operations or long-term storage.
In addition, since fine unevenness is provided as a means for improving frictional resistance, the slidability between the elevation base 21 and the first elevation section 22 or between the first elevation section 22 and the second elevation section 23 is excellent. Therefore, the lifting mechanism 20 can be operated to lift and lower the retainer such as the inner tray 10 and the rod-shaped composition for external use 2 smoothly with a light force.

第２実施形態によれば、第１螺合部と第２螺合部の何れか一方又は双方における相対向面２５に存する突起とその対向面との間のクリアランスが狭まっているため、第１昇降部２２Ａの動きを制御することができ、上記第１実施形態と同様に異音を抑制することができる。また、第２実施形態によれば、加工面積が狭くて済むという利点を有する。 According to the second embodiment, since the clearance between the protrusion present on the opposing surface 25 and the opposing surface of either or both of the first threaded portion and the second threaded portion is narrowed, the first The movement of the lifting section 22A can be controlled, and abnormal noise can be suppressed in the same manner as in the first embodiment. Moreover, according to the second embodiment, there is an advantage that the processing area is small.
