Description
本発明は、粘性のあるリップグロスを収納するリップグロス塗布容器に関し、特に、唇を塗布する塗布具から発生する悪臭を防止するリップグロス塗布容器に関する。 The present invention relates to a lip gloss application container for storing viscous lip gloss, and more particularly to a lip gloss application container for preventing malodor generated from an applicator for applying lips.
粘性のある液状化粧料であるリップグロスは、唇の荒れを防止しながら望む唇の色と輝きが保たれるようにし、また、唇の健康と美容効果を得るために用いられている。従来の図５（ａ）及び５（ｂ）に示す化粧品容器は、リップグロスを収容する容器ボディー１、上面にリップグロスを噴出させる複数の噴出穴２５が形成された噴出部材２、その噴出部材２を覆う蓋７とで構成され、そして、容器ボディー１の上部には、リップグロス液９を収容する円筒形のシリンダー１１が嵌合されている（特許文献１参照）。また、図６（ａ）及び６（ｂ）に示す化粧料収納容器は、リップグロス等の液状化粧料３が収納される液状化粧料収納筒９、この液状化粧料収納筒９の下端部に液状化粧料３を流出させるために取付けられたアプリケーター１０、このアプリケーター１０の流出口１４を閉じる棒状の閉塞材６８とで構成され、液状化粧料用キャップ１５が上記液状化粧料収納筒９に着脱可能に取付けられている（特許文献２参照）。 Lip gloss, a viscous liquid cosmetic, is used to maintain desired lip color and shine while preventing roughening of the lips, and to obtain lip health and beauty effects. The conventional cosmetic container shown in FIGS. 5 (a) and 5 (b) includes a container body 1 for storing lip gloss, an ejection member 2 having a plurality of ejection holes 25 for ejecting lip gloss on the upper surface, and the ejection member. 2 and a cylindrical cylinder 11 containing a lip gloss liquid 9 is fitted on the upper portion of the container body 1 (see Patent Document 1). 6 (a) and 6 (b) includes a liquid cosmetic container 9 in which a liquid cosmetic 3 such as lip gloss is stored, and a lower end portion of the liquid cosmetic container 9. The applicator 10 is attached to allow the liquid cosmetic 3 to flow out, and a rod-shaped closing material 68 that closes the outlet 14 of the applicator 10, and the liquid cosmetic cap 15 is attached to and detached from the liquid cosmetic storage cylinder 9. It is attached so that it is possible (refer patent document 2).
上記化粧品容器及び化粧料収納容器は、塗布部（特許文献１の噴出部材２及び特許文献２のアプリケーター１０に相当）でリップグロスを唇に塗布するので、唇についていた食品などの汚れが上記塗布部の吐出口（特許文献１の噴出穴２５及び特許文献２の流出口１４に相当）に移って容器に入り、容器の中で雑菌が繁殖して悪臭を発生させるといわれている。そのため、ユーザーは雑菌が容器の中に入らないように、使用後に容器の塗布部を清掃して雑菌の繁殖の防止に努めている。しかしながら、最悪の場合には雑菌の繁殖による悪臭がひどくなり使用途中の容器の廃棄をせざるをえない等の問題点があった。 In the cosmetic container and the cosmetic container, the lip gloss is applied to the lips at the application portion (equivalent to the ejection member 2 of Patent Document 1 and the applicator 10 of Patent Document 2). It is said that it moves into the discharge port (corresponding to the ejection hole 25 of Patent Document 1 and the outlet 14 of Patent Document 2) and enters the container, and germs propagate in the container and generate malodor. Therefore, users try to prevent the propagation of germs by cleaning the application part of the container after use so that the germs do not enter the container. However, in the worst case, the bad odor due to the propagation of various germs became so severe that there was a problem that the container during use had to be discarded.
ところで、本発明者等は、熱可塑性樹脂であるポリエチレン樹脂、ポリプロピレン樹脂、ポリエチレンテレフタレート樹脂及びポリアミド樹脂からなる群から選ばれる一種の樹脂中に、中実の球状ガラスビーズをその配合率が４０〜７０重量％の範囲において含有するペレットを、発明の名称「ガラス含有成形用ペレット及びその製造方法」として特許出願をし、その発明は、平成２１年８月２６日の特許公報（特許文献３参照）に掲載されている。その公知のペレットを射出成形機に投入して、球状ガラスビーズ含有の溶融樹脂を金型に射出して成形されたガラス含有樹脂成形体は、その表面にスキン層が形成されないこと、そして、その表面に球状ガラスビーズ及び充填剤が存在することで充填剤の作用が発揮できることを見出し、発明の名称「充填剤・ガラス含有樹脂成形体」を完成して特許出願をし、その発明は、平成２２年５月１２日の特許公報（特許文献４参照）に掲載されている。 By the way, the inventors of the present invention have a solid spherical glass bead ratio of 40 to 40 in one kind of resin selected from the group consisting of polyethylene resin, polypropylene resin, polyethylene terephthalate resin and polyamide resin which are thermoplastic resins. A patent application was filed for a pellet containing 70% by weight in the name of the invention "Pellet for glass-containing molding and method for producing the same", and the invention was disclosed in the patent publication of August 26, 2009 (see Patent Document 3). ) The known pellets are put into an injection molding machine, and the glass-containing resin molded body formed by injecting molten resin containing spherical glass beads into a mold has no skin layer formed on the surface thereof, and The inventors found that the action of the filler can be exhibited by the presence of spherical glass beads and filler on the surface, and completed a patent application by filing the name of the invention “filler / glass-containing resin molded product”. It is published in the patent gazette (refer patent document 4) of May 12, 2010.
特許文献４に記載の実施例には、例えば、実施例３５に見られるように、ポリプロピレン樹脂、球状ガラスビーズ、抗菌剤及び抗かび剤を配合したものが示されている。銀抗菌剤として０．１重量％の銀ガラスを用いており、抗菌性試験は、ＪＩＳ Ｚ２８０１に基づき抗菌効果を調べたところ、従来の銀ガラス含有樹脂成形体が用いている０．５重量％と同等の抗菌効果があることが判明した。そこで、本発明者等は、ポリプロピレン樹脂に５０重量％の球状ガラスビーズと０．１重量％又は０．５重量％の銀ガラスを含有する、特許文献１及び２に示すような塗布部及び蓋を備える容器を作製して、雑菌の繁殖による悪臭の発生を防止できるか否かのテストを試みた。 In the example described in Patent Document 4, for example, as seen in Example 35, a blend of polypropylene resin, spherical glass beads, an antibacterial agent and an antifungal agent is shown. 0.1% by weight of silver glass is used as the silver antibacterial agent, and the antibacterial test was conducted to examine the antibacterial effect based on JIS Z2801, and 0.5% by weight used by conventional silver glass-containing resin moldings It was found to have an antibacterial effect equivalent to Accordingly, the present inventors have disclosed an application part and a lid as shown in Patent Documents 1 and 2, which contain 50% by weight of spherical glass beads and 0.1% by weight or 0.5% by weight of silver glass in polypropylene resin. We tried to test whether it was possible to prevent the generation of malodor due to the propagation of various bacteria.
特許文献２に示すような容器の構造では、雑菌などの汚れの付いた塗布部の流出口を、棒状の閉塞材を押し込んで閉塞する構造なので、この構造は悪臭の発生を促進するものと考えられる。一方、特許文献１に示すような容器の構造は、上記閉塞材を押し込んで閉塞する構造ではないので、この構造は悪臭の発生を防止しやすいものと考えられる。そこで、特許文献１及び２に示すような容器を作製して、５名のパネラーにより官能評価を行ったところ、両方の構造ともに悪臭の発生を防止できないことが分かった。 In the structure of the container as shown in Patent Document 2, since the outlet of the application part with dirt such as germs is blocked by pushing a rod-shaped plugging material, this structure is considered to promote the generation of malodor. It is done. On the other hand, since the structure of the container as shown in Patent Document 1 is not a structure in which the closing material is pushed in and closed, this structure is considered to easily prevent the generation of malodor. Then, when the container as shown to patent document 1 and 2 was produced and sensory evaluation was performed by five panelists, it turned out that generation | occurrence | production of malodor cannot be prevented with both structures.
それ故に、本発明は、上記従来技術の問題点に鑑み、上記容器の中で雑菌が繁殖して悪臭を発生させない、リップグロスを収納するリップグロス塗布容器を提供することを課題とする。 Therefore, an object of the present invention is to provide a lip gloss coating container for storing lip gloss, in which miscellaneous germs propagate in the container and do not generate malodor.
本発明者等は、上記課題を解決するために鋭意検討を重ねた結果、蓋のポリプロピレン樹脂に、また、塗布部のポリエチレン樹脂に平均粒径１０〜４０μｍの中実の球状ガラスビーズを４０〜７０重量％、平均粒径１〜１０μｍの銀ガラスを１〜３重量％の範囲で含有させると、塗布部の傾斜面及び蓋の棒状閉塞材が唇についていた食品などの汚れにより発生する悪臭を防止することができることを見出し、本発明を完成するに至った。

Both preheated to the same temperature as the melting temperature of 230 ° C. are added, kneaded at 230 ° C. with a screw speed of 100 times / minute, extruded into a 3 mm diameter rod, cooled with water, cut into a length of 4 mm, and pellets As a result, a molding pellet was obtained. The molding pellets were put into a hopper of an injection molding machine, melted at 230 ° C., and injected into a mold having the shape of the coating part.
上述した本発明の第１及び第２の形態は、蓋及び塗布部の金型に接した表面が、スキン層を形成しないこと、そして、その表面に球状ガラス及び銀ガラスが存在することで抗菌作用が発揮される。
リップグロス塗布容器を使用する際には、必要とするリップグロスの量をチューブの側面を押すことで調節し、上記吐出口から押し出されたリップグロスを上下の唇に塗布することで、上記湾曲形状の傾斜面にリップグロスが均一に広がり、上下の唇にむらなく塗ることができる。
The first and second embodiments of the present invention described above are antibacterial because the surface of the lid and the coating part in contact with the mold does not form a skin layer, and spherical glass and silver glass are present on the surface. The effect is demonstrated.
When using a lip gloss application container, adjust the amount of lip gloss required by pressing the side of the tube, and apply the lip gloss pushed out from the discharge port to the upper and lower lips, thereby Lip gloss spreads evenly on the inclined surface of the shape and can be applied evenly to the upper and lower lips.
しかしながら、使用後にリップグロス塗布容器の塗布部の傾斜面を清掃して雑菌の繁殖の防止に努めないと、唇についていた食品などの汚れが上記塗布部の吐出口に移ってチューブ内に入り、その中のリップグロスに雑菌が繁殖して悪臭を発生させるといわれている。 However, if you do not try to prevent the propagation of germs by cleaning the inclined surface of the application part of the lip gloss application container after use, dirt such as food on the lips will move to the discharge port of the application part and enter the tube, It is said that various bacteria propagate on the lip gloss and cause bad odor.
そこで、図３に示す傾斜面４１の形状が湾曲状で均一の厚さでない上記塗布部４のリップグロス塗布容器１の実施例１、２と、図４に示す傾斜面４１′の形状が平面状の本発明の第２の形態の例である、均一の厚さのリップグロス塗布容器の実施例３、４と、実施例１及び実施例３と同じ形状の比較例１、２を作製して、５名のパネラーにより官能評価を行った。
実施例は、蓋にポリプロピレン樹脂を、塗布部にポリエチレン樹脂を用いて、平均粒径１０〜４０μｍの中実の球状ガラスビーズを４７〜４９重量％、平均粒径１〜１０μｍの銀ガラスを１〜３重量％の範囲で含有するペレットで蓋と塗布部を成形した。
また、比較例は、蓋にポリプロピレン樹脂を、塗布部にポリエチレン樹脂を用いて、平均粒径１０〜４０μｍの中実の球状ガラスビーズを５０重量％含有するペレットで蓋と塗布部を成形した。
In Examples, a polypropylene resin is used for a lid and a polyethylene resin is used for an application part, and 47 to 49% by weight of solid spherical glass beads having an average particle diameter of 10 to 40 μm and 1 silver glass having an average particle diameter of 1 to 10 μm are used. The lid and the coating part were formed with pellets contained in the range of ˜3% by weight.
In the comparative example, the lid and the coating part were formed with pellets containing 50% by weight of solid spherical glass beads having an average particle diameter of 10 to 40 μm using a polypropylene resin for the lid and a polyethylene resin for the coating part.
（臭いの測定）
リップグロス塗布容器を５名のパネラーにより官能評価した。
通常、リップグロスは、使用開始後１週間程度経過すると容器内に入った雑菌の増殖により悪臭が問題となるので、本測定では１週間連続で毎日３回使用した後、３６℃で相対湿度９５％以上の保温器中で１週間保存したリップグロスについて測定を行った。
臭いは、無臭を０とした５段階評価でスコア付けし、パネラー５名の平均値を示した。 ここで、平均値が３未満であれば許容可能な臭いと判断される。
The lip gloss coating container was sensory-evaluated by five panelists.
Usually, when lip gloss is used for about one week after the start of use, bad odor becomes a problem due to the growth of germs in the container. Therefore, in this measurement, the lip gloss is used three times daily for one week, then at 36 ° C. with a relative humidity of 95. Measurements were made on lip gloss that was stored for 1 week in an incubator at% or higher.
The odor was scored by a five-step evaluation with odorless being 0, and the average value of 5 panelists was shown. Here, if the average value is less than 3, it is determined that the odor is acceptable.
表２のとおり、実施例１〜４のリップグロス塗布容器に入ったリップグロスについては、臭いの問題は全く無かった。一方、比較例１、２のリップグロス塗布容器に入ったリップグロスについては、悪臭がするとの評価であった。 As shown in Table 2, the lip gloss contained in the lip gloss application containers of Examples 1 to 4 had no odor problem. On the other hand, the lip gloss contained in the lip gloss coating containers of Comparative Examples 1 and 2 was evaluated as having a bad odor.
（雑菌増殖に関するシミユレーション）
唇に付着した汚れがリップグロス塗布容器の吐出口から容器内に入り、雑菌が増殖する過程のシミユレーションを行った。本シミユレーションは、リップグロス塗布容器の吐出口からの汚染伝播を遮断できるかどうかを確認するためのものである。
ＪＩＳ Ｌ １９０２繊維製品の抗菌性試験方法・抗菌効果に準じ、ブイヨン液体培地（１／２０Ｎ）を容積１０ｍｌのリップグロス塗布容器に８ｍｌ充填した。一方、本ＪＩＳ試験方法で使用されるコットン製の標準白布を使用し、この標準白布の表面に黄色ブドウ球菌（Ｓｔａｐｈｙｌｏｃｏｃｃｕｓ ａｕｒｅｕｓ ＮＢＲＣ１３２７６）懸濁液（菌濃度３．８×１０８ＣＦＵ／ｍｌ）を散布し、上記実施例及び比較例の容器の塗布部で表面をなでた。その後、これらの容器を３５℃、４８時間保持し、容器内の液体培地中の生残菌数を求めた。なお、菌数測定は、ハートインフージョン寒天培地（栄研化学株式会社製品）を用い、混釈平板法により求めた。
その結果を表３に示す。
The process of simulating the growth of germs was performed by the dirt adhering to the lips entering the container through the discharge port of the lip gloss coating container. This simulation is for confirming whether or not contamination propagation from the discharge port of the lip gloss coating container can be blocked.
According to the antibacterial test method and antibacterial effect of JIS L 1902 fiber product, 8 ml of a lip gloss coating container with a volume of 10 ml of bouillon liquid medium (1/20 N) was filled. On the other hand, a standard white cloth made of cotton used in the present JIS test method was used, and a Staphylococcus aureus NBRC13276 suspension (bacterial concentration of 3.8 × 10 8 CFU / ml) was used on the surface of the standard white cloth. After spraying, the surface of the container of the examples and comparative examples was smeared. Thereafter, these containers were kept at 35 ° C. for 48 hours, and the number of surviving bacteria in the liquid medium in the container was determined. The number of bacteria was determined by the pour plate method using a heart infusion agar medium (product of Eiken Chemical Co., Ltd.).
The results are shown in Table 3.
表３のとおり、実施例１〜４のリップグロス塗布容器では、問題となるような黄色ブドウ球菌の生残菌数では無かった。一方、比較例１、２のリップグロス塗布容器では、明らかに問題となる黄色ブドウ球菌の生残菌数であった。 As shown in Table 3, in the lip gloss-coated containers of Examples 1 to 4, the number of surviving bacteria of Staphylococcus aureus was not a problem. On the other hand, in the lip gloss coating containers of Comparative Examples 1 and 2, the number of S. aureus surviving bacteria was clearly a problem.
表２及び表３が示す結果を考察する。
特許文献４に記載の銀ガラス・ガラス含有樹脂成形体が、その表面にスキン層が形成されないこと、そして、その表面に球状ガラスビーズ及び銀ガラスが存在することで、銀ガラスの抗菌作用が発揮できるものであることは、上述したとおりである。そこで、段落５及び６に記載したように、０．５重量％の銀ガラス含有の塗布部及び蓋を備える容器を作製して、その容器での雑菌の繁殖による悪臭の発生を防止できるか否かのテストの結果は、悪臭が防止できないことを示したが、銀ガラスの配合割合が１〜３重量％であれば悪臭の発生を防止できることが判明した。そして、実施例１、２とその傾斜面４１′の厚さが異なる実施例３、４は、官能評価の臭いの問題が全く無いことから、傾斜面４１、４１′の厚さが棒状閉塞材２１と嵌り合う厚さであれば悪臭の発生を防止できることが判明した。
Consider the results shown in Tables 2 and 3.
The silver glass / glass-containing resin molded article described in Patent Document 4 exhibits the antibacterial action of silver glass due to the absence of a skin layer on the surface and the presence of spherical glass beads and silver glass on the surface. What can be done is as described above. Therefore, as described in paragraphs 5 and 6, whether or not it is possible to produce a container having a coating part and a lid containing 0.5% by weight of silver glass and prevent the generation of malodor due to the propagation of germs in the container The test results showed that bad odors could not be prevented, but it was found that the generation of bad odors could be prevented if the silver glass content was 1 to 3% by weight. In Examples 3 and 4 in which the thicknesses of the inclined surfaces 41 'are different from those in Embodiments 1 and 2, the thickness of the inclined surfaces 41 and 41' is a rod-shaped closing material because there is no problem of odor of sensory evaluation. It was found that if the thickness fits with 21, the generation of malodor can be prevented.
