Description

本発明は、エアゾール容器の弁に取り付けられる塗布体に関し、特に、弁を開放したとき速やかに液剤を浸出させることができる塗布体に関するものである。   The present invention relates to an applicator attached to a valve of an aerosol container, and more particularly to an applicator capable of rapidly leaching a liquid agent when the valve is opened.

エアゾール容器に目的の内容物（液剤）と噴射剤を充填し、弁を開放することで液剤を噴射するエアゾール製品が提供されている。このようなエアゾール製品では、液剤が消炎鎮痛剤や害虫忌避剤、ローション、育毛剤等のように直接皮膚に噴射する医薬品や医薬部外品、或いは化粧品である場合、噴射された液剤が飛散するという問題が生じる。このため、エアゾール容器の弁に装着して液剤の飛散を防止する塗布体が提案されている（例えば特許文献１参照）。   There is provided an aerosol product in which an aerosol container is filled with a target content (liquid agent) and a propellant and the valve is opened to inject the liquid agent. In such aerosol products, if the liquid is a medicine, quasi-drug, or cosmetic that is directly injected onto the skin, such as an anti-inflammatory analgesic, pest repellent, lotion, hair restorer, etc., the injected liquid is scattered The problem arises. For this reason, the application body which is attached to the valve | bulb of an aerosol container and prevents scattering of a liquid agent is proposed (for example, refer patent document 1).

特許文献１に記載された発明は、焼結多孔質体を介して液剤を人体に塗布するに際し、適正な塗布量を確保し得る塗布用アクチュエーター付のエアゾール製品に関するものである。この塗布用アクチュエーターは、全体が球の一部である椀状の焼結多孔質体によって形成されており、外表面が塗布面としての機能を有している。また、焼結多孔質体の側面には装着部としての機能を有する突起が形成されており、この突起を介して保持部材に装着されている。   The invention described in Patent Document 1 relates to an aerosol product with a coating actuator that can secure an appropriate coating amount when a liquid agent is applied to a human body via a sintered porous body. This application actuator is formed of a bowl-like sintered porous body that is a part of a sphere as a whole, and the outer surface functions as an application surface. In addition, a protrusion having a function as a mounting portion is formed on the side surface of the sintered porous body, and the protrusion is mounted on the holding member via the protrusion.

特許文献１に記載された焼結多孔質体は、ポリエチレン、ポリプロピレン等の高分子材料からなる粒体を焼結成形して形成されている。この焼結多孔質体では、標準平均気孔径が５μｍ〜１００μｍの範囲にあり、この隙間を通って塗布すべき物質（液剤）が表面に浸出することとなる。このように、焼結多孔質体には全体にわたって略均一な隙間が形成されているため、焼結多孔質体の表面を人体に接触させて押圧させたときに作用する力によってバルブ（弁）を開放することができる。そして、弁を通過した液剤は、焼結多孔質体の全体に浸透して全表面から略均一に浸出する。   The sintered porous material described in Patent Document 1 is formed by sintering and molding particles made of a polymer material such as polyethylene and polypropylene. In this sintered porous body, the standard average pore diameter is in the range of 5 μm to 100 μm, and the substance (liquid agent) to be applied leaches out to the surface through this gap. As described above, the sintered porous body is formed with a substantially uniform gap over the entire surface, so that a valve (valve) is applied by a force acting when the surface of the sintered porous body is pressed against the human body. Can be released. And the liquid agent which passed the valve osmose | permeates the whole sintered porous body, and leaches out from the whole surface substantially uniformly.

上記特許文献１に記載された焼結多孔質体を用いた場合、弁を開放してから液剤が表面に浸出するまでに時間がかかるという問題が指摘されており、浸出するまでの時間を短縮することが要求されている。   When the sintered porous material described in Patent Document 1 is used, it has been pointed out that it takes time for the liquid agent to leach to the surface after the valve is opened, and the time to leach is reduced. Is required to do.

また、弁を通過した液剤が焼結多孔質体に形成されている隙間に残留してしまい、無駄が生じるという問題も指摘されている。   Further, it has been pointed out that the liquid agent that has passed through the valve remains in a gap formed in the sintered porous body, resulting in waste.

本発明の目的は、液剤を速やかに浸出させることができ、且つ無駄の少ない塗布体を提供することにある。   An object of the present invention is to provide an application body that can quickly leach out a liquid agent and has little waste.

上記課題を解決するために本発明に係る塗布体は、液剤と噴射剤を充填したエアゾール容器の弁に取り付けられる塗布体であって、前記塗布体は、エアゾール容器の弁を構成するステムに取り付けられる取付部材と、前記取付部材に装着される塗布部材と、を有し、前記取付部材は、天板と、前記天板の中心から突出して形成されエアゾール容器の弁を構成するステムに取り付けられる取付部と、前記天板の外周に形成されたリング状の凹溝からなる装着部と、を有して構成され、前記塗布部材は高分子焼結多孔質体からなり、予め設定された標準平均気孔径を有する塗布部と、前記塗布部の外周に形成され標準平均気孔径が前記塗布部の標準平均気孔径よりも小さく且つ前記取付部材に形成された装着部に嵌合されるリング状の嵌合部と、を有して構成され、前記塗布部材の嵌合部を前記取付部材の装着部に嵌合して装着したものである。   In order to solve the above problems, an application body according to the present invention is an application body attached to a valve of an aerosol container filled with a liquid agent and a propellant, and the application body is attached to a stem constituting the valve of the aerosol container. And an application member attached to the attachment member, and the attachment member is attached to a top plate and a stem that protrudes from the center of the top plate and constitutes a valve of the aerosol container. A mounting portion and a mounting portion formed of a ring-shaped concave groove formed on the outer periphery of the top plate, and the coating member is made of a polymer sintered porous body, and is a preset standard. An applicator having an average pore diameter, and a ring shape that is formed on the outer periphery of the applicator and has a standard average pore diameter smaller than the standard average pore diameter of the applicator and fitted to a mounting part formed on the mounting member Fitting part of It is configured to have, in which the fitting portion of the coating member is mounted is fitted on the mounting portion of the mounting member.

本発明に係る塗布体では、高分子焼結多孔質体（以下、単に「多孔質体」という）からなる塗布部材が、予め設定された標準平均気孔径を有する塗布部と、該塗布部の外周に形成され標準平均気孔径が塗布部の標準平均気孔径よりも小さい嵌合部と、を有する。このため、塗布部に於ける流路抵抗を嵌合部に於ける流路抵抗よりも小さくすることができる。   In the application body according to the present invention, an application member made of a polymer sintered porous body (hereinafter simply referred to as “porous body”) includes an application part having a preset standard average pore diameter, A fitting portion formed on the outer periphery and having a standard average pore diameter smaller than the standard average pore diameter of the application portion. For this reason, the flow path resistance in the application part can be made smaller than the flow path resistance in the fitting part.

このため、弁を通過した液剤は、嵌合部に対する浸透よりも塗布部に対する浸透が円滑となり、単位時間当たりに塗布部を通過する量が多くなって速やかに表面に浸出することができる。従って、液剤が、弁を開放してから塗布部材の塗布部に浸透して表面に浸出するまでの時間を短縮することができる。   For this reason, the liquid agent that has passed through the valve is more smoothly permeated into the application part than permeation into the fitting part, and the amount of the liquid agent that passes through the application part per unit time can be leached to the surface quickly. Accordingly, it is possible to shorten the time from when the liquid agent opens the valve until it permeates the application portion of the application member and leaches to the surface.

また、嵌合部の標準平均気孔径が小さいため、この嵌合部に残留する液剤の量を軽減させることができる。このため、液剤の無駄を排除することができる。   Moreover, since the standard average pore diameter of the fitting portion is small, the amount of the liquid agent remaining in the fitting portion can be reduced. For this reason, waste of the liquid agent can be eliminated.

以下、本発明に係る塗布体の実施例について図１〜図３を用いて説明する。図１に示す塗布体Ａは、図３に示すエアゾール容器Ｂの弁を構成するステム１０に取り付けられて塗布用エアゾール製品を構成するものである。特に、塗布体Ａは、弁を開放したときにエアゾール容器Ｂに収容された液剤の速やかな表面への浸出を実現すると共に、無駄を軽減させるように構成されている。   Hereinafter, the Example of the application body which concerns on this invention is described using FIGS. 1-3. The application body A shown in FIG. 1 is attached to the stem 10 which comprises the valve | bulb of the aerosol container B shown in FIG. 3, and comprises the aerosol product for application | coating. In particular, the application body A is configured to realize rapid leaching of the liquid agent accommodated in the aerosol container B to the surface and reduce waste when the valve is opened.

先ず、図３により、本実施例に係る塗布体Ａを用いた塗布用エアゾール製品の構成について簡単に説明する。前述したように、塗布用エアゾール製品は、部分的に記載したエアゾール容器Ｂと、このエアゾール容器Ｂの弁に取り付けられた塗布体Ａとを有して構成されている。塗布体Ａはエアゾール容器Ｂの弁を構成するステム１０に取り付けられており、該塗布体Ａを人体の皮膚に押し付けたときに作用する力によってステム１０を押し下げて弁を開放し得るように構成されている。   First, the configuration of an aerosol product for application using the application body A according to this example will be briefly described with reference to FIG. As described above, the aerosol product for application includes the aerosol container B partially described, and the application body A attached to the valve of the aerosol container B. The application body A is attached to the stem 10 constituting the valve of the aerosol container B, and is configured so that the valve can be opened by pushing down the stem 10 by a force acting when the application body A is pressed against the human skin. Has been.

エアゾール容器Ｂには、例えば、消炎鎮痛剤や害虫忌避剤、ローション、育毛剤等のように直接皮膚に噴射する医薬品や医薬部外品、化粧品等の目的に応じて調整された液剤と、噴射剤と、が充填されている。そして、ステム１０を押し下げるのに応じて、噴射剤によって加圧された液剤を噴射することが可能である。   In the aerosol container B, for example, a liquid agent adjusted according to the purpose of a medicine, a quasi-drug, a cosmetic, or the like directly sprayed onto the skin, such as an anti-inflammatory analgesic, a pest repellent, a lotion, a hair restorer, etc. And an agent. And according to pushing down the stem 10, it is possible to inject the liquid pressurized by the propellant.

エアゾール容器Ｂに充填された液剤を噴射するための噴射剤は、特に限定するものではない。一般的なエアゾール製品で噴射剤として利用されている液化石油ガス（ＬＰＧ）やジメチルエーテル（ＤＭＥ）、或いは炭酸ガスや窒素ガス等の圧縮ガス、更にはハイドロフルオロカーボン（ＨＦＣ）等の代替フロンガス、等のガスを選択的に利用することが可能である。   The propellant for injecting the liquid agent filled in the aerosol container B is not particularly limited. Liquefied petroleum gas (LPG) and dimethyl ether (DME) used as a propellant in general aerosol products, compressed gas such as carbon dioxide and nitrogen gas, and alternative fluorocarbon such as hydrofluorocarbon (HFC), etc. Gas can be selectively used.

エアゾール容器Ｂの肩部には肩カバー１１が取り付けられている。この肩カバー１１は、キャップ１２を着脱可能に取り付ける機能を有するものであり、外径がエアゾール容器Ｂの外径と略等しく形成されている。また、下端部にはエアゾール容器Ｂに取り付けられる突起状の取付部１１ａが内側に向けて形成され、上端部にはキャップ１２を取り付けるための取付部１１ｂが形成されている。そして、肩カバー１１にキャップ１２が着脱可能に取り付けられている。   A shoulder cover 11 is attached to the shoulder of the aerosol container B. The shoulder cover 11 has a function of detachably attaching the cap 12 and has an outer diameter substantially equal to the outer diameter of the aerosol container B. Further, a projecting attachment portion 11a attached to the aerosol container B is formed inward at the lower end portion, and an attachment portion 11b for attaching the cap 12 is formed at the upper end portion. A cap 12 is detachably attached to the shoulder cover 11.

次に、塗布体Ａの構成について説明する。塗布体Ａはエアゾール容器Ｂの弁を構成するステム１０に取り付けられる取付部材１と、該取付部材１に装着された多孔質体からなる塗布部材２と、を有して構成されている。   Next, the configuration of the coated body A will be described. The application body A includes an attachment member 1 attached to a stem 10 constituting a valve of the aerosol container B, and an application member 2 made of a porous body attached to the attachment member 1.

塗布体Ａの取付部材１は、天板１ａと、該天板１ａの中心から下方に突出して形成されステム１０を嵌合すると共に該ステム１０と連通した孔１ｂを有するボス状の取付部１ｃと、天板１ａの外周に沿ってリング状の凹溝として形成され塗布部材２を装着するための装着部１ｄと、を有して構成されている。   The attachment member 1 of the coated body A is a top plate 1a and a boss-like attachment portion 1c that is formed to protrude downward from the center of the top plate 1a, has a stem 10 fitted therein, and has a hole 1b that communicates with the stem 10. And a mounting portion 1d that is formed as a ring-shaped concave groove along the outer periphery of the top plate 1a and for mounting the coating member 2 thereon.

特に、装着部１ｄは、内周が天板１ａの外周から下方に立ち下がった立下片１ｅによって規定され、外周が立上片１ｆによって規定され、底部がリング状の底片１ｇによって規定されている。そして、装着部１ｄに塗布部材２の嵌合部２ｂを嵌合させたとき、該嵌合部２ｂを立下片１ｅと立上片１ｆ及び底片１ｇによって保持している。   In particular, the mounting portion 1d has an inner periphery defined by a falling piece 1e falling downward from an outer periphery of the top plate 1a, an outer periphery defined by a rising piece 1f, and a bottom portion defined by a ring-shaped bottom piece 1g. Yes. When the fitting portion 2b of the application member 2 is fitted to the mounting portion 1d, the fitting portion 2b is held by the falling piece 1e, the rising piece 1f, and the bottom piece 1g.

上記の如き形状を持った取付部材１を構成する材料は特に限定するものではなく、ポリエチレンやポリプロピレン等の熱可塑性樹脂を用いることが可能である。特に、取付部材１を構成する材料は、成形後多少の弾力性を発揮し得るものであることが好ましく、このような弾力性を有することで、塗布部材２を装着する際に、該塗布部材２に寸法のばらつきが生じているような場合でも、このばらつきを吸収することが可能である。   The material constituting the mounting member 1 having the above shape is not particularly limited, and a thermoplastic resin such as polyethylene or polypropylene can be used. In particular, the material constituting the mounting member 1 is preferably one that can exhibit some elasticity after molding, and having such elasticity allows the application member 2 to be attached when the application member 2 is mounted. Even when there is a dimensional variation in 2, this variation can be absorbed.

塗布部材２は全体が浅いカップを伏せた形状を有しており、伏せたカップの頂部分（カップの底となる部分）に塗布部２ａが形成され、カップの外周部分に嵌合部２ｂが形成されている。即ち、塗布部材２の塗布部２ａは表面が球の一部の形状を持って形成されており、外周部分の嵌合部２ｂは取付部材１に設けた凹溝からなる装着部１ｄに嵌合するリング状に突起として形成されている。このように、塗布部材２の外周部分にリング状の嵌合部２ｂが形成されることによって、カップの中心には円筒状の凹溝２ｃが形成され、該凹溝２ｃの底面である取付部材１の天板１ａと対向する面に対向面２ｄが形成される。   The coating member 2 has a shape in which the cup is shallow as a whole, the coating part 2a is formed on the top part of the cup (the part that becomes the bottom of the cup), and the fitting part 2b is formed on the outer peripheral part of the cup. Is formed. That is, the coating part 2a of the coating member 2 is formed so that the surface has a shape of a part of a sphere, and the fitting part 2b of the outer peripheral part is fitted to the mounting part 1d formed of a concave groove provided in the mounting member 1. It is formed as a projection in a ring shape. Thus, by forming the ring-shaped fitting portion 2b on the outer peripheral portion of the application member 2, a cylindrical concave groove 2c is formed at the center of the cup, and the mounting member is the bottom surface of the concave groove 2c. A facing surface 2d is formed on the surface facing the top plate 1a.

上記した対向面２ｄは、塗布部２ａの表面の曲率と略等しい曲率を持った球面の一部として形成されている。このため、対向面２ｄに対応する塗布部材２は塗布部２ａの表面２ａの間で略均等な厚さを有することとなる。即ち、塗布部材２の塗布部２ａは、全面にわたって略均等な厚さを持って形成されている。そして、嵌合部２ｂは境界２ｅを介して塗布部２ａと接続されている。   The facing surface 2d is formed as a part of a spherical surface having a curvature substantially equal to the curvature of the surface of the application portion 2a. For this reason, the application member 2 corresponding to the opposing surface 2d has a substantially uniform thickness between the surfaces 2a of the application part 2a. That is, the application part 2a of the application member 2 is formed with a substantially uniform thickness over the entire surface. And the fitting part 2b is connected with the application part 2a via the boundary 2e.

塗布部材２に形成された凹溝２ｃの深さは、取付部材１の天板１ａの外周に形成された立下片１ｅの高さよりも大きい寸法を有している。このため、塗布部材２の嵌合部２ｂを取付部材１の装着部１ｄに嵌合させたとき、取付部材１の天板１ａと塗布部材２の対向面２ｄとの間に、凹溝２ｃの深さと立下片１ｅの高さとの差に応じた高さを持った空隙３が形成される。   The depth of the concave groove 2 c formed in the application member 2 has a dimension larger than the height of the falling piece 1 e formed on the outer periphery of the top plate 1 a of the mounting member 1. For this reason, when the fitting part 2b of the application member 2 is fitted to the mounting part 1d of the attachment member 1, the concave groove 2c is formed between the top plate 1a of the attachment member 1 and the opposing surface 2d of the application member 2. A gap 3 having a height corresponding to the difference between the depth and the height of the falling piece 1e is formed.

尚、上記空隙３は、ステム１０から取付部材１の孔１ｂを経て噴射された液剤を分散させるための空間となるものである。この空隙３の深さは特に限定するものではなく、噴射すべき液剤の性質に応じて適宜設定することが好ましい。しかし、使用する毎に空隙３に液剤が滞留するため、空隙３の深さが余りに大きくなると無駄になる液剤の量が多くなる虞があり、空隙３の深さが小さいと塗布部材２の塗布部２ａに万遍なく液剤を供給するのが難しくなる虞がある。   In addition, the said space | gap 3 becomes a space for disperse | distributing the liquid agent injected through the hole 1b of the attachment member 1 from the stem 10. FIG. The depth of the gap 3 is not particularly limited, and is preferably set as appropriate according to the properties of the liquid to be injected. However, since the liquid agent stays in the gap 3 every time it is used, if the depth of the gap 3 becomes too large, there is a risk that the amount of the liquid agent that is wasted increases, and if the depth of the gap 3 is small, the application member 2 is applied. There is a possibility that it may be difficult to uniformly supply the liquid agent to the portion 2a.

塗布部材２はポリエチレン又はポリプロピレン或いはエチレン・酢酸ビニルコポリマーの粒体を原料とし、この原料を焼結成形することによって構成されている。即ち、塗布部材２は、予め設定された粒度の範囲に管理されたポリエチレン又はポリプロピレン或いはエチレン・酢酸ビニルコポリマーの粒体を成形型に収容した後、高圧、高温下で成形して製造されている。このように塗布部材２の原料としてポリエチレン、ポリプロピレン、エチレン・酢酸ビニルコポリマー等の中から選択された材料を用いることによって、塗布使用時の皮膚に対する感触を向上させることが可能である。   The applicator member 2 is formed by using polyethylene, polypropylene, or ethylene / vinyl acetate copolymer particles as a raw material, and sintering the raw material. That is, the application member 2 is manufactured by accommodating polyethylene, polypropylene, or ethylene / vinyl acetate copolymer particles controlled in a predetermined particle size range in a mold, and then molding under high pressure and high temperature. . As described above, by using a material selected from polyethylene, polypropylene, ethylene / vinyl acetate copolymer and the like as a raw material of the application member 2, it is possible to improve the feel to the skin during application use.

上記塗布部材２では、粒度が管理された多数の粒体が互いに強固に結び付いて形成されるため、隣接する孔が互いに連続して網目状の隙間（気孔）が形成される。このため、塗布部材２を孔径が５μｍ〜１００μｍの範囲にあるように厳密に管理した多孔質体によって構成することが可能である。   In the coating member 2, a large number of particles whose particle sizes are controlled are tightly connected to each other, so that adjacent holes are continuous with each other to form a mesh-like gap (pore). For this reason, it is possible to comprise the application | coating member 2 with the porous body managed strictly so that a hole diameter may exist in the range of 5 micrometers-100 micrometers.

本発明に係る塗布部材２は、塗布部２ａと嵌合部２ｂとが互いに異なる標準平均気孔径で形成されている。即ち、嵌合部２ｂの標準平均気孔径は、塗布部２ａの標準平均気孔径よりも小さく形成されている。このように、嵌合部２ｂの標準平均気孔径が塗布部２ａの標準平均気孔径よりも小さいことによって、噴射された液材が塗布部材２に浸透する際に、塗布部２ａに於ける浸透速度が嵌合部２ｂに於ける浸透速度よりも大きくなる。このため、液材が塗布部２ａの表面に浸出するまでの時間を短縮することが可能となる。   In the application member 2 according to the present invention, the application part 2a and the fitting part 2b are formed with different standard average pore diameters. That is, the standard average pore diameter of the fitting part 2b is formed smaller than the standard average pore diameter of the application part 2a. As described above, when the standard average pore diameter of the fitting part 2b is smaller than the standard average pore diameter of the application part 2a, when the sprayed liquid material penetrates the application member 2, the penetration in the application part 2a. The speed becomes larger than the penetration speed in the fitting portion 2b. For this reason, it becomes possible to shorten time until a liquid material leaches out to the surface of application part 2a.

塗布部２ａの標準平均気孔径の具体的な数値と嵌合部２ｂの標準平均気孔径の具体的な数値を、夫々限定するものではなく、相対的に塗布部２ａの標準平均気孔径が嵌合部２ｂの標準平均気孔径よりも大きければ良い。   The specific numerical value of the standard average pore diameter of the application part 2a and the specific numerical value of the standard average pore diameter of the fitting part 2b are not limited respectively, and the standard average pore diameter of the application part 2a is relatively fitted. What is necessary is just to be larger than the standard average pore diameter of the joint part 2b.

例えば、塗布部２ａの標準平均気孔径を５０μｍ〜１００μｍの範囲に設定したとき、嵌合部２ｂの標準平均気孔径を５μｍ〜４０μｍの範囲に設定して塗布部材２を構成している。また、塗布部２ａの標準平均気孔径を１０μｍ〜５０μｍの範囲に設定したとき、嵌合部２ｂの標準平均気孔径を１０μｍ以下の範囲に設定して塗布部材２を構成している。   For example, when the standard average pore diameter of the application part 2a is set in the range of 50 μm to 100 μm, the standard average pore diameter of the fitting part 2b is set in the range of 5 μm to 40 μm to configure the application member 2. Moreover, when the standard average pore diameter of the application part 2a is set in the range of 10 μm to 50 μm, the standard average pore diameter of the fitting part 2b is set in the range of 10 μm or less to constitute the application member 2.

このように、嵌合部２ｂの標準平均気孔径を塗布部２ａの標準平均気孔径よりも小さくすることによって、嵌合部２ｂでは液材の浸透に対する抵抗が塗布部２ａの抵抗と比較して大きくなる。このため、相対的に塗布部２ａに於ける液剤の浸透が速やかに行われることとなり、エアゾール容器Ｂからの液剤の吐出量が一定であれば、塗布部２ａの表面に於ける浸出が速やかに行われることになる。   Thus, by making the standard average pore diameter of the fitting part 2b smaller than the standard average pore diameter of the application part 2a, the resistance against penetration of the liquid material is compared with the resistance of the application part 2a in the fitting part 2b. growing. For this reason, the penetration of the liquid agent in the application part 2a is relatively quickly performed, and if the discharge amount of the liquid agent from the aerosol container B is constant, the leaching on the surface of the application part 2a is promptly performed. Will be done.

特に、嵌合部２ｂの標準平均気孔径は０であって良い。この場合、エアゾール容器Ｂから噴射された液剤が嵌合部２ｂに浸透することがなく、全量が塗布部２ａに浸透して表面から浸出することとなる。このため、塗布部２ａに於けるより速やかな液剤の浸出を実現することが可能となる。   In particular, the standard average pore diameter of the fitting portion 2b may be zero. In this case, the liquid sprayed from the aerosol container B does not permeate the fitting part 2b, and the entire amount permeates the application part 2a and leaches out from the surface. For this reason, it is possible to realize more rapid leaching of the liquid agent in the application part 2a.

上記の如く、塗布部２ａの標準平均気孔径を嵌合部２ｂの標準平均気孔径よりも大きくした塗布部材２を製造する方法は限定するものではない。例えば、塗布部２ａを形成するための粒体と、嵌合部２ｂを形成するための粒体を、異なる径とし、夫々の粒体を順に成形型に充填して焼結成形することで良い。或いは、予め塗布部２ａに対応する部分を圧縮成形すると共に嵌合部２ｂに対応する部分を圧縮成形しておき、両者を重ねた後焼結成形しても良い。更に、嵌合部２ｂに対応する部分を、気孔を有することのないリング状の材を成形しておき、この材と塗布部２ａに対応する部分とを合体させて焼結成形することでも良い。   As described above, the method for manufacturing the application member 2 in which the standard average pore diameter of the application part 2a is larger than the standard average pore diameter of the fitting part 2b is not limited. For example, the granule for forming the application portion 2a and the granule for forming the fitting portion 2b may have different diameters, and each of the granules may be sequentially filled in a mold and sintered. . Alternatively, the portion corresponding to the application portion 2a may be compression molded in advance, the portion corresponding to the fitting portion 2b may be compression molded, and both may be stacked and then sintered. Furthermore, a ring-shaped material that does not have pores may be formed in the portion corresponding to the fitting portion 2b, and the material and the portion corresponding to the application portion 2a may be combined and sintered. .

上記の如く形成された取付部材１、塗布部材２では、取付部材１の装着部１ｄに塗布部材２の嵌合部２ｂを嵌合させることで、該塗布部材２を取付部材１に装着して塗布体Ａを構成することが可能である。そして、取付部材１の取付部１ｃをエアゾール容器Ｂのステム１０に嵌合させることで、塗布用エアゾール製品を構成することが可能である。   In the attachment member 1 and the application member 2 formed as described above, the application member 2 is attached to the attachment member 1 by fitting the fitting portion 2b of the application member 2 to the attachment portion 1d of the attachment member 1. The application body A can be configured. And it is possible to comprise the aerosol product for application by fitting the attachment part 1c of the attachment member 1 to the stem 10 of the aerosol container B.

本件発明者等は、本発明に係る塗布部材２と、現在提供されている塗布部材とを用いて、噴射された液剤が塗布部の表面から浸出するまでの時間を比較する実験を行った。   The inventors of the present invention conducted an experiment using the coating member 2 according to the present invention and the currently provided coating member to compare the time until the sprayed liquid leached from the surface of the coating part.

この実験は、塗布部材２のテストピースを、塗布部２ａの標準平均気孔径を１７μｍ〜３０μｍとし、嵌合部２ｂの標準平均気孔径を０として複数製作した。現在提供されている比較塗布部材２は、塗布部及び嵌合部を含む全体の標準平均気孔径を１７μｍ〜３０μｍとして政策されている。そして、夫々の塗布部材を有する塗布体をエアゾール容器Ｂのステム１０に取り付け、ステム１０を押圧して弁を開放した後、噴射された液剤が塗布体の表面から浸出するまでの時間を測定した。   In this experiment, a plurality of test pieces of the application member 2 were manufactured with the standard average pore diameter of the application part 2a being 17 μm to 30 μm and the standard average pore diameter of the fitting part 2b being 0. The comparative application member 2 that is currently provided has a policy that the overall standard average pore diameter including the application part and the fitting part is 17 μm to 30 μm. And the application body which has each application member was attached to the stem 10 of the aerosol container B, and after pressing the stem 10 and opening a valve, the time until the sprayed liquid agent leached from the surface of the application body was measured. .

上記実験の結果、嵌合部２ｂの標準平均気孔径を０とした塗布部材２では、液剤が塗布部２ａの表面から浸出するまでの平均時間が１．３５秒であった。これに対し、現在提供されている比較塗布部材では、１．６２秒であった。この結果から、本発明に係る塗布部材２を有する塗布体Ａでは、現在提供されている塗布体と比較して、液剤の塗布部の表面への浸出時間が短縮されているといえる。   As a result of the experiment, in the coating member 2 in which the standard average pore diameter of the fitting portion 2b was 0, the average time until the liquid leached from the surface of the coating portion 2a was 1.35 seconds. On the other hand, in the comparative application member currently provided, it was 1.62 seconds. From this result, it can be said that in the application body A having the application member 2 according to the present invention, the leaching time to the surface of the application part of the liquid agent is shortened as compared with the application body currently provided.

また、塗布部材２の嵌合部２ｂの標準平均気孔径が、塗布部２ａの標準平均気孔径よりも小さいことから、嵌合部２ｂに残留する液剤は、全体が同じ標準平均気孔径を有する現在提供されている塗布部材と比較してより少なくなり、無駄な液剤を軽減させることが可能となる。   Moreover, since the standard average pore diameter of the fitting part 2b of the application member 2 is smaller than the standard average pore diameter of the application part 2a, the liquid agent remaining in the fitting part 2b has the same standard average pore diameter as a whole. Compared with the application member currently provided, it becomes less and it becomes possible to reduce a useless liquid agent.

尚、前述の実施例では、塗布部材２の嵌合部２ｂを塗布部２ａの裏面側にリング状に突起させて構成したが、この構成にのみ限定するものではない。例えば、塗布部材２の嵌合部２ｂを、塗布部２ａの外周側面を含むリング状に形成したものであって良い。即ち、図１に示す嵌合部２ｂが塗布部材２の外周側面側を球状の表面に到達させた形状であっても良い。   In the above-described embodiment, the fitting portion 2b of the application member 2 is formed in a ring shape on the back side of the application portion 2a. However, the present invention is not limited to this configuration. For example, the fitting part 2b of the application member 2 may be formed in a ring shape including the outer peripheral side surface of the application part 2a. That is, the fitting part 2b shown in FIG. 1 may have a shape in which the outer peripheral side surface of the application member 2 reaches a spherical surface.

上記の如く、塗布部材２の外周側面を含む嵌合部２ｂを構成する場合、塗布部２ａと嵌合部２ｂの境界２ｅは、塗布部材２の外周側面の直線部分と塗布部２ａの球面部分とが交差する部位から嵌合部２ｂのリング状突起の根本を結ぶテーパ状であることが好ましい。嵌合部２ｂをこのように形成することで、液剤が浸出すべき塗布面をより限定することが可能となり、速やかな液剤の浸透と浸出を実現することが可能となる。   As described above, when the fitting portion 2b including the outer peripheral side surface of the coating member 2 is configured, the boundary 2e between the coating portion 2a and the fitting portion 2b is a straight portion on the outer peripheral side surface of the coating member 2 and a spherical portion of the coating portion 2a. It is preferable to have a tapered shape that connects the roots of the ring-shaped protrusions of the fitting portion 2b from the portion where the crossing points intersect. By forming the fitting portion 2b in this way, it is possible to further limit the application surface from which the liquid agent should be leached, and to realize quick penetration and leaching of the liquid agent.

本発明に係る塗布体では、液剤を人体に塗布するエアゾール製品に利用して有利である。   In the application body which concerns on this invention, it is advantageous to utilize for the aerosol product which apply | coats a liquid agent to a human body.
