Description
自動車の室内の送風口に設置して使用される自動車用揮散器であって、長期間に亘って芳香液を揮散できる自動車用揮散器に関する。 The present invention relates to an automobile volatilizer which is installed in an air outlet in an automobile and is used, and which can volatilize an aromatic liquid for a long period of time.
従来、自動車の室内に芳香等を付与して快適空間にするために、芳香液を揮散させる揮散器が広く使用されている。自動車の室内で使用される揮散器には、ダッシュボード等に置くタイプ（載置タイプ）、ルームミラー等に吊り下げるタイプ（吊り下げタイプ）、エアコンやデフロスターの送風口に取り付けるタイプ（送風口取付タイプ）等がある（例えば、特許文献１〜３参照）。 Conventionally, a volatilizer that volatilizes an fragrance liquid has been widely used in order to impart fragrance or the like to a comfortable space in an automobile interior. Volatilizers used indoors of automobiles include a type that is placed on a dashboard (mounting type), a type that is hung on a rearview mirror (hanging type), and a type that is attached to the air outlet of an air conditioner or defroster (air outlet installation). Type) and the like (see, for example, Patent Documents 1 to 3).
載置タイプや吊り下げタイプの自動車用揮散器は、芳香液を自然蒸散させるので、芳香液の減量速度（揮散速度）は比較的一定になり易いというメリットがあるものの、設置場所で邪魔になったり、視界を遮ったりすることがある。一方、送風口取付タイプの自動車用揮散器は、コンパクトであり設置場所で邪魔にならないというメリットがあるものの、エンジン起動後にエアコンの送風を利用して芳香液を揮散させているため、エアコン稼働時の送風により芳香液の減量速度が急激に上昇するという欠点がある。 Since the stationary type and hanging type automobile volatilizer evaporates the aromatic liquid naturally, there is an advantage that the weight loss rate (volatilization rate) of the aromatic liquid tends to be relatively constant, but it becomes an obstacle at the installation location. Or it may block your view. On the other hand, the air vent-mounted type automobile volatilizer has the advantage of being compact and does not get in the way at the installation location, but since the air conditioner is used to volatilize the aromatic liquid after the engine is started, the air conditioner is operating. There is a drawback that the rate of weight loss of the fragrance liquid increases sharply due to the ventilation of the air conditioner.
このように、送風口取付タイプの自動車用揮散器では、コンパクトであるが故に収容されている芳香液量が少ない上、送風時の減量速度が速いため、芳香液がなくなるのが早く、使用期間が短いことが問題となっている。 In this way, in the blower-mounted type automobile volatilizer, the amount of fragrance liquid contained is small because it is compact, and the weight loss rate at the time of blowing is fast, so the fragrance liquid disappears quickly and the period of use. Is short, which is a problem.
本発明の目的は、自動車のエアコンの送風口に設置して使用される自動車用揮散器であって、長期間に亘って芳香液を揮散できる自動車用揮散器を提供することである。 An object of the present invention is to provide an automobile volatilizer which is installed and used at an air outlet of an air conditioner of an automobile and can volatilize an aromatic liquid for a long period of time.
本発明者は、前記課題を解決すべく鋭意検討を行ったところ、芳香液と、吸液部材と、容器とを含み、当該容器に当該芳香液が含浸された当該吸液部材が収容されてなる揮散器において、当該容器にエアコンの送風口と対向する面のみに通気孔を設け、且つ当該容器の内部空間の容積に対する当該通気孔の総開口面積の比率を０．００１〜０．０１５ｍｍ2／ｍｍ3に設定することにより、自動車のエアコンの送風口に設置して使用すると、エアコンの稼働時の送風による急激な芳香液の揮散を抑制しつつ、エアコンが稼働していない場合には芳香液の過剰な揮散を抑制でき、使用期間の長期化が図られることを見出した。本発明は、かかる知見に基づいて、更に検討を重ねることにより完成したものである。 As a result of diligent studies to solve the above problems, the present inventor has included an fragrance liquid, a liquid absorbing member, and a container, and the container contains the liquid absorbing member impregnated with the fragrance liquid. The container is provided with ventilation holes only on the surface facing the air outlet of the air conditioner, and the ratio of the total opening area of the ventilation holes to the volume of the internal space of the container is 0.001 to 0.015 mm 2. By setting it to / mm 3 , when it is installed and used in the air outlet of an automobile air conditioner, it suppresses the rapid volatilization of aromatic liquid due to the air blown when the air conditioner is operating, and it is aromatic when the air conditioner is not operating. It has been found that excessive volatilization of the liquid can be suppressed and the period of use can be extended. The present invention has been completed by further studies based on such findings.
即ち、本発明は、下記に掲げる態様の発明を提供する。
項１． 自動車のエアコンの送風口に設置して使用される自動車用揮散器であって、

［容器］
容器は、芳香液が含浸された吸液部材を収容する部材であって、空気の流入及び流出が可能な通気孔が設けられている。
[container]
The container is a member that houses a liquid absorbing member impregnated with an aromatic liquid, and is provided with a vent hole that allows air to flow in and out.
本発明において、容器は、エアコンの送風口と対向する面のみに通気孔が設けられている。送風口取付タイプの自動車用揮散器では、容器の通気孔を介して、送風口から吹き出された空気を容器の内部空間に流入させ、且つ芳香液から揮散された香りを伴う空気を容器外に流出させることにより、自動車の室内に香りを付与する。従来の送風口取付タイプの自動車用揮散器では、容器の通気孔は、エアコンの送風口と対向する面と、その反対側又は側面との双方に設けられており、エアコンの稼働時には送風口と対向する面の通気孔から空気を流入させ、芳香液から揮散された香りを伴う空気をその反対側又は側面の通気孔から流出させる構造になっている。このような構造の場合にはエアコンを稼働した際に空気を流入させる通気孔と空気を流出させる通気孔がそれぞれ異なっているので、エアコン稼働時に送風口から吹き出された空気を制限せずにそのまま容器内に流入させることになり、その結果、容器の内部空間に流入する空気量と流出する空気量が多くなり、芳香液の減量速度（揮散速度）が不可避的に高まってしまう（図１のＡ参照）。これに対して、本発明の自動車用揮散器では、容器の通気孔は、エアコンの送風口と対向する面のみに設けられており、空気の流入と空気の流出は同じ通気孔が担っているので、エアコンを稼働した際に送風口から吹き出された空気の流入は、容器外に流出する空気の抵抗を受けて制限され、その結果、容器の内部空間に流入する空気量と流出する空気量が減り、エアコン稼働時に芳香液の減量速度（揮散速度）が急激に上昇するのを抑制できる（図１のＢ参照）。図１における各符号は、以下の通りである：１は「容器」、２は「芳香液が含浸された吸液部材」、３は「自動車のエアコンの送風口と対向する面に設けられた通気孔」、４は「自動車のエアコンの送風口と対向する面の反対面に設けられた通気孔」、５は「空気の流れ」。 In the present invention, the container is provided with ventilation holes only on the surface facing the air outlet of the air conditioner. In a blower-mounted type automobile volatilizer, the air blown out from the air outlet is allowed to flow into the internal space of the container through the ventilation holes of the container, and the air with the fragrance volatilized from the fragrance liquid is discharged to the outside of the container. By letting it flow out, it gives a scent to the interior of the automobile. In the conventional air vent-mounted type automobile volatilizer, the ventilation holes of the container are provided on both the surface facing the air vent of the air conditioner and the opposite side or the side surface. The structure is such that air flows in through the ventilation holes on the opposite surfaces, and the air with the scent volatilized from the fragrance liquid flows out from the ventilation holes on the opposite side or the side surface thereof. In the case of such a structure, the ventilation holes that allow air to flow in and the ventilation holes that allow air to flow out when the air conditioner is operated are different, so the air blown out from the air outlet when the air conditioner is operating is not restricted and remains as it is. As a result, the amount of air flowing into and out of the container's internal space increases, and the rate of weight loss (volatilization rate) of the aromatic liquid inevitably increases (Fig. 1). See A). On the other hand, in the automobile volatilizer of the present invention, the ventilation holes of the container are provided only on the surface facing the air outlet of the air conditioner, and the same ventilation holes are responsible for the inflow and outflow of air. Therefore, the inflow of air blown out from the air outlet when the air conditioner is operated is limited by the resistance of the air flowing out of the container, and as a result, the amount of air flowing into and the amount of air flowing out into the internal space of the container. It is possible to suppress a rapid increase in the weight loss rate (volatilization rate) of the aromatic liquid when the air conditioner is operating (see B in FIG. 1). Each reference numeral in FIG. 1 is as follows: 1 is a "container", 2 is a "liquid absorbing member impregnated with an aromatic liquid", and 3 is "provided on a surface facing the air outlet of an automobile air conditioner". "Vents", 4 are "vents provided on the opposite surface of the air conditioner of the automobile facing the air outlet", and 5 are "air flow".
容器に設けられる通気孔の数については、エアコンの送風口と対向する面のみに設けられ、且つ後述する容積と総開口面積の比率を満たすことを限度として特に制限されないが、例えば、１〜２０個、好ましくは１〜１０個、より好ましくは１〜６個、更に好ましくは１〜３個、特に好ましくは１個が挙げられる。 The number of ventilation holes provided in the container is not particularly limited as long as it is provided only on the surface facing the air outlet of the air conditioner and satisfies the ratio of the volume and the total opening area described later, but is not particularly limited, for example, 1 to 20. The number is preferably 1 to 10, more preferably 1 to 6, still more preferably 1 to 3, and particularly preferably 1.
本発明において、容器は、内部空間の容積に対する通気孔の総開口面積の比率が０．００１〜０．０１５ｍｍ2／ｍｍ3を満たす。このような比率を満たすことにより、エアコンの稼働時に容器の内部空間に流入する空気量と流出する空気量を適切にコントロールし、エアコンの稼働時の芳香液の減量速度（揮散速度）の急激な上昇を抑制することが可能になる。また、エアコンを稼働していない場合では、前述する比率を満たすことによって芳香液が過度に自然揮散するのを抑制でき、エアコンを稼働していない際に芳香液の過剰に減量するのを抑制することが可能になる。所望の香りの強さを備えさせつつ、使用期間のより一層の長期化を図るという観点から、当該比率として、好ましくは０．００１〜０．０１０ｍｍ2／ｍｍ3、より好ましくは０．００１〜０．００５ｍｍ2／ｍｍ3が挙げられる。本発明、「開口面積」とは、通気孔が伸びる方向に対して垂直な面に投影したときの開口（穴）している領域の面積であり、「総開口面積」とは、通気孔が１個ある場合には当該通気孔の開口面積であり、通気孔が複数ある場合には、複数の通気孔の開口面積の総和である。また、前記比率の範囲の値は、小数点以下４桁を四捨五入して、小数点以下３桁を有効数字として表される値である。 In the present invention, the container satisfies the ratio of the total opening area of the ventilation holes to the volume of the internal space of 0.001 to 0.015 mm 2 / mm 3. By satisfying such a ratio, the amount of air flowing into the internal space of the container and the amount of air flowing out during the operation of the air conditioner are appropriately controlled, and the rate of weight loss (volatilization rate) of the aromatic liquid during the operation of the air conditioner is rapid. It becomes possible to suppress the rise. In addition, when the air conditioner is not operating, it is possible to suppress excessive natural volatilization of the fragrance liquid by satisfying the above-mentioned ratio, and it is possible to suppress excessive reduction of the fragrance liquid when the air conditioner is not operating. Will be possible. From the viewpoint of further extending the period of use while providing the desired intensity of fragrance, the ratio is preferably 0.001 to 0.010 mm 2 / mm 3 , more preferably 0.001 to 0.001. 0.005 mm 2 / mm 3 can be mentioned. In the present invention, the "opening area" is the area of the opening (hole) area when projected onto a plane perpendicular to the direction in which the ventilation holes extend, and the "total opening area" is the area of the ventilation holes. When there is one, it is the opening area of the ventilation hole, and when there are a plurality of ventilation holes, it is the total of the opening areas of the plurality of ventilation holes. Further, the value in the range of the ratio is a value represented by rounding off four digits after the decimal point and using three digits after the decimal point as significant figures.
本発明において、容器に設けられる通気孔の総開口面積については、前記比率を充足する範囲であればよいが、例えば、１〜３００ｍｍ2、好ましくは５〜２５０ｍｍ2、より好ましくは１０〜１６０ｍｍ2、更に好ましくは１０〜７０ｍｍ2が挙げられる。 In the present invention, the total opening area of the ventilation holes provided in the container may be a range that satisfies the above ratio, but is, for example, 1 to 300 mm 2 , preferably 5 to 250 mm 2 , more preferably 10 to 160 mm 2. , More preferably 10 to 70 mm 2 .
また、本発明において、容器の内部空間の容積については、前記比率を充足する範囲であればよいが、例えば、１０００〜５００００ｍｍ3、好ましくは５０００〜３００００ｍｍ3、より好ましくは１００００〜２００００ｍｍ3が挙げられる。 Further, in the present invention, the volume of the internal space of the container may be a range that satisfies the above ratio, and examples thereof include 1000 to 50000 mm 3 , preferably 5000 to 30000 mm 3 , and more preferably 1000 to 20000 mm 3. Be done.
また、容器には、自動車のエアコンの送風口に取り付けるための取付部を有していることが好ましい。更に、容器は、内部空間に収容した吸液部材が固定できる支持部が設けられていてもよい。また、容器は、芳香液が含浸された吸液部材を収容できるように、複数のパーツに分けられて、芳香液が含浸された吸液部材を収容した後に当該複数のパーツが固定されていればよい。 Further, it is preferable that the container has an attachment portion for attaching to the air outlet of the air conditioner of the automobile. Further, the container may be provided with a support portion to which the liquid absorbing member housed in the internal space can be fixed. Further, the container is divided into a plurality of parts so as to accommodate the liquid absorbing member impregnated with the aromatic liquid, and the plurality of parts are fixed after accommodating the liquid absorbing member impregnated with the aromatic liquid.

Evaluation of Weight Loss Rate of Fragrance Liquid Each volatilizer was allowed to stand in an environment of a temperature of 40 ° C. and a humidity of 15 to 20% RH for 24 hours, and the weight of the volatilizer before and after standing was measured. The weight loss rate (g / day) was calculated by subtracting the weight of the volatilizer after standing for 24 hours from the weight of the volatilizer before standing.
５．香りの強度の評価
自動車（フィット、本田技研工業株式会社）のエンジンをかけて、車の窓を全開にして送風の状態で風量を最大にして、水温警告灯（青）が消えるまで待った。水温警告灯（青）が消えたら、送風をやめて窓を閉めた。次いで、助手席側の中央側にあるエアコンルーバーに前記揮散器を取り付け、風量を「２」及びエアコンの温度を「Ｌｏ」に設定し、香りの強度を評価した。その後、車の窓を全開にして十分な換気を行った後に、風量を「２」及びエアコンの温度を「Ｈｉ」に設定し、香りの強度を評価した。なお、香りの評価を行う際には、運転席側と助手席側のドア側にある送風口は閉じた状態にしておいた。
5. Evaluation of fragrance intensity The engine of the car (Fit, Honda Motor Co., Ltd.) was started, the window of the car was fully opened, the air volume was maximized in the state of ventilation, and the water temperature warning light (blue) was extinguished. When the water temperature warning light (blue) went out, I stopped blowing and closed the window. Next, the volatilizer was attached to the air conditioner louver on the center side of the passenger seat, the air volume was set to "2", the temperature of the air conditioner was set to "Lo", and the intensity of the scent was evaluated. Then, after the car window was fully opened and sufficient ventilation was performed, the air volume was set to "2" and the temperature of the air conditioner was set to "Hi", and the intensity of the scent was evaluated. When evaluating the scent, the air outlets on the driver's side and the passenger's side doors were kept closed.
また、香りの強度は、訓練された専門パネラー６名により、下記判定基準に従って評点化し、６名の評点の内、最大及び最小の評点を除いてエアコンの温度を「Ｌｏ」及び「Ｈｉ」した場合のそれぞれについて平均値を算出した。そして、各揮散器について、「Ｌｏ」の場合の評点の平均値と「Ｈｉ」の場合の評点の平均値を更に平均し、香りの強度の総合平均評点を算出した。
＜香りの強度の判定基準＞
芳香消臭脱臭剤協議会が定める［ＩＩ］効力試験方法の［ＩＩ］−１芳香剤効力試験方法に準拠した方法で香りの強度を評価した。香りの強度の判定は、６段階臭気強度表示法によって、目標とする香り強度を「４：強いにおい（コントロール強度）」にし設定して、０：無臭、１：やっと感知できるにおい（検知閾値）、２：何のにおいであるかわかる弱いにおい（認知閾値）、３：楽に感知できるにおい、４：強いにおい、５：強烈なにおい、に評点化し、７名のパネラー（臭気判定士又は臭覚テスト合格者）による平均値を算出した。
In addition, the intensity of the scent was scored according to the following criteria by 6 trained professional panelists, and the temperature of the air conditioner was set to "Lo" and "Hi" except for the maximum and minimum scores among the 6 scores. The average value was calculated for each case. Then, for each volatilizer, the average value of the scores in the case of "Lo" and the average value of the scores in the case of "Hi" were further averaged to calculate the total average score of the fragrance intensity.
<Criteria for scent intensity>
The intensity of the scent was evaluated by a method based on the [II] -1 air freshener efficacy test method of the [II] efficacy test method established by the Air Freshener Deodorant Council. To determine the scent intensity, set the target scent intensity to "4: strong odor (control intensity)" by the 6-step odor intensity display method, 0: odorless, 1: finally perceptible odor (detection threshold). , 2: Weak odor that tells what odor is (cognitive threshold), 3: Easily perceptible odor, 4: Strong odor, 5: Strong odor, and 7 panelists (odor judge or odor test) The average value by successful applicants) was calculated.
得られた結果を表３に示す。送風口と対向する面側のみに通気孔を設け、且つ内部空間の容積に対する通気孔の総開口面積の比率が０．０１５ｍｍ2／ｍｍ3超である容器に、芳香液を含浸させた吸液部材を収容した揮散器では、香りの強さの点では問題なかったものの、芳香液の減量速度が１．０ｇ／ｄａｙ以上であり、短期間しか香りを呈することができないものであった（比較例１〜４）。また、送風口と対向する面側とその反対面側の双方に通気孔を設け、且つ内部空間の容積に対する通気孔の総開口面積の比率を０．０１５ｍｍ2／ｍｍ3以下にしても、減量速度が１ｇ／ｄａｙ以上と速く、短期間しか香りを呈することができないものであった（比較例５）。これに対して、送風口と対向する面側のみに通気孔を設け、且つ内部空間の容積に対する通気孔の総開口面積の比率が０．００１〜０．０１５ｍｍ2／ｍｍ3である容器を使用した揮散器では、減量速度が１．ｇ／ｄａｙを下回っており、長期間に亘って香りを呈することが可能であり、更に、香りの強さも十分に満足できるものであった。 The results obtained are shown in Table 3. A liquid absorbing liquid impregnated with an aromatic liquid in a container in which ventilation holes are provided only on the side facing the air outlet and the ratio of the total opening area of the ventilation holes to the volume of the internal space is more than 0.015 mm 2 / mm 3. In the volatilizer containing the members, there was no problem in terms of the intensity of the scent, but the weight loss rate of the fragrance liquid was 1.0 g / day or more, and the scent could be exhibited only for a short period of time (comparison). Examples 1 to 4). Further, even if ventilation holes are provided on both the side facing the air outlet and the side opposite to the air vent, and the ratio of the total opening area of the ventilation holes to the volume of the internal space is 0.015 mm 2 / mm 3 or less, the weight is reduced. The speed was as high as 1 g / day or more, and the scent could be exhibited only for a short period of time (Comparative Example 5). On the other hand, a container in which ventilation holes are provided only on the side facing the air outlet and the ratio of the total opening area of the ventilation holes to the volume of the internal space is 0.001 to 0.015 mm 2 / mm 3 is used. The weight loss rate is 1. It was less than g / day, and it was possible to exhibit the scent for a long period of time, and the intensity of the scent was also sufficiently satisfactory.

得られた揮散器を温度４０℃、湿度１５〜２０％ＲＨの環境に１６８時間静置し、静置前及び静置後の揮散器の重量を測定した。静置前及び静置後の揮散器の重量を測定した。静置前の揮散器の重量から１６８時間静置後の揮散器の重量を差し引いた値を７で除することにより、減量速度（ｇ／ｄａｙ）を算出した。また、得られた揮散器を用いて前記試験例１と同様の方法で、香りの強度を評価した。 The obtained volatilizer was allowed to stand in an environment of a temperature of 40 ° C. and a humidity of 15 to 20% RH for 168 hours, and the weights of the volatilizer before and after standing were measured. The weight of the volatilizer before and after standing was measured. The weight loss rate (g / day) was calculated by dividing the value obtained by subtracting the weight of the volatilizer after standing for 168 hours from the weight of the volatilizer before standing by 7. In addition, the intensity of the scent was evaluated using the obtained volatilizer in the same manner as in Test Example 1.
得られた結果を表５に示す。この結果、芳香液の組成を変更しても、芳香液を含浸させた吸液部材を、送風口と対向する面側のみに通気孔を設け、且つ内部空間の容積に対する通気孔の総開口面積の比率が０．００１〜０．０１５ｍｍ2／ｍｍ3である容器に収容した揮散器は、減量速度が１．ｇ／ｄａｙが遅く、香りの強さも十分に満足できるものであった。 The results obtained are shown in Table 5. As a result, even if the composition of the fragrance liquid is changed, the liquid absorbing member impregnated with the fragrance liquid is provided with ventilation holes only on the surface side facing the air outlet, and the total opening area of the ventilation holes with respect to the volume of the internal space. The volatilizer housed in a container having a ratio of 0.001 to 0.015 mm 2 / mm 3 has a weight loss rate of 1. The g / day was slow and the intensity of the scent was sufficiently satisfactory.
