Therefore, such aerosol products are likely to be over-used by spraying more than necessary times.

The aerosol valve is a mechanism for taking out the aerosol composition filled in the aerosol container, and closes the opening of the aerosol container. Moreover, the aerosol valve of this embodiment is provided with a metering chamber for temporarily storing the aerosol composition taken out of the aerosol container. The volume of the metering chamber corresponds to the volume of the aerosol composition sprayed by one injection. The volume of the metering chamber of this embodiment is 1 to 3 mL.

In addition, the opening and closing member includes a stem that slides up and down in conjunction with the injection member. The sliding of the stem switches the communication (injection state) and shutoff (non-injection state) of the aerosol composition. The aerosol valve is formed with a housing bore for taking in the aerosol composition from the aerosol container and a stem bore for delivering the taken-in aerosol composition to the spray member. The housing hole is formed in the housing. The stem hole is formed in the stem.

Further, the internal pressure of the aerosol valve at 25 ° C. is preferably 0.7 MPa or less, and more preferably 0.6 MPa or less. By adjusting the internal pressure of the aerosol valve in such a range, the aerosol product can be easily adjusted so that the equivalent noise level of 10 seconds of the jet noise at the time of discharge becomes 62 dB or more, and as a result, the aerosol composition The user can further realize that the injection is sufficient. In addition, when the internal pressure of an aerosol valve is less than 0.3 Mpa, an aerosol product tends to become small in a jet noise, and it is hard to be realized by a user. In addition, if the internal pressure of the aerosol valve is less than 0.3 MPa, the aerosol composition may drip from the injection port after the injection. On the other hand, if the internal pressure of the aerosol valve exceeds 0.7 MPa, the aerosol composition may leak from the aerosol container. The internal pressure of the aerosol valve is, for example, PGM-10KE compact pressure sensor (manufactured by Kyowa Electric Industry) attached to a WGA-710C instrumentation conditioner (manufactured by Kyowa Electric Industry) at 25 ° C as the aerosol valve. It can measure by connecting.

　本実施形態のエアゾール製品は、使用者によって噴射ボタンが操作されることにより、ステム機構およびエアゾールバルブが作動し、エアゾールバルブの定量室内と外部とが連通する。これにより、エアゾールバルブの定量室内のエアゾール組成物は、エアゾールバルブの定量室内と外部との圧力差に従って一定量が取り出され、噴射部材の噴口から噴射される。 In the aerosol product of the present embodiment, when the injection button is operated by the user, the stem mechanism and the aerosol valve are operated, and the metering chamber of the aerosol valve communicates with the outside. As a result, a predetermined amount of the aerosol composition in the metering chamber of the aerosol valve is taken out according to the pressure difference between the metering chamber of the aerosol valve and the outside, and is jetted from the injection port of the injection member.
　本実施形態のエアゾール製品は、１回あたりの噴射量が１～３ｍＬとなるよう調整されている。１回あたりの噴射量は、１．０ｍＬ以上であればよい。また、１回あたりの噴射量は、３．０ｍＬ以下であればよく、２．５ｍＬ以下であることが好ましい。１回あたりの噴射量が１．０ｍＬ未満である場合、噴射されたエアゾール組成物は、噴射音が小さくなりやすく、使用者に実感されにくい。一方、１回あたりの噴射量が３．０ｍＬを超える場合、エアゾール製品は、定量室の設計が困難になりやすい。 The aerosol product of this embodiment is adjusted so that the injection amount per injection is 1 to 3 mL. The injection amount per injection may be 1.0 mL or more. The injection amount per injection may be 3.0 mL or less, preferably 2.5 mL or less. When the injection amount per injection is less than 1.0 mL, the jetted aerosol composition tends to have a low jet noise and is hard to be perceived by the user. On the other hand, when the injection amount per time exceeds 3.0 mL, the aerosol product tends to make it difficult to design a metering chamber.
　エアゾール製品全体の説明に戻り、本実施形態のエアゾール製品は、普通騒音計におけるＡ特性での噴射音の１０秒間の等価騒音レベル（ＬAeq）が６２ｄＢ以上である。等価騒音レベル（ＬAeq）は、６２ｄＢ以上となるよう調整されていればよく、６４ｄＢ以上であることが好ましく、６７ｄＢ以上であることがより好ましい。なお、等価騒音レベル（ＬAeq）の上限は特に限定されない。噴射時の騒音の観点から、等価騒音レベル（ＬAeq）は、９０ｄＢ以下であることが好ましい。等価騒音レベル（ＬAeq）が６２ｄＢ以上である場合、使用者は、エアゾール組成物が充分に噴射されていることを実感できる。そのため、使用者は、必要回数以上に噴射することが抑止され得る。なお、等価騒音レベル（ＬAeq）は、時間的に変動する場合の騒音レベルを定量的に把握するための数値であり、JIS Z8731-1999に基づき、ある一定の測定時間内（本実施形態では１０秒間）における変動騒音の平均２乗音圧に等しい平均２乗音圧を与える連続定常音の騒音レベルとして定義される。等価騒音レベル（ＬAeq）の値が小さいほど、騒音が少なく静かであるといえる。また、Ａ特性とは、騒音計による測定につかわれる人間の聴覚を考慮した周波数の重み付け特性をいう。本実施形態の等価騒音レベル（ＬAeq）は、たとえば、普通騒音計ＮＬ－２１（リオン（株）製）にて、エアゾール製品の噴口の真横１０ｃｍの距離から、Ａ特性にて測定することにより算出することができる。また、本実施形態の等価騒音レベル（ＬAeq）は、バックグラウンドの等価騒音レベル（ＬAeq）が３６ｄＢである場合の騒音レベルである。本実施形態のエアゾール製品は、上記等価騒音レベル（ＬAeq）を達成していることにより、通常使用される場面（たとえば、静かな居室等。この場合のバックグラウンドは、３５～３７ｄＢ程度である）において、充分に、使用者に使用していることが実感できる。 Returning to the description of the entire aerosol product, the aerosol product of the present embodiment has an equivalent noise level (L Aeq ) of 10 seconds for the jet noise at the A characteristic in the ordinary noise level meter at 62 dB or more. The equivalent noise level (L Aeq ) may be adjusted to be 62 dB or more, preferably 64 dB or more, and more preferably 67 dB or more. The upper limit of the equivalent noise level (L Aeq ) is not particularly limited. From the viewpoint of noise during injection, the equivalent noise level (L Aeq ) is preferably 90 dB or less. When the equivalent noise level (L Aeq ) is 62 dB or more, the user can realize that the aerosol composition is sufficiently injected. Therefore, the user can be prevented from injecting more than necessary times. The equivalent noise level (L Aeq ) is a numerical value for quantitatively grasping the noise level in the case of temporal variation, and based on JIS Z8731-1999, within a certain measurement time (in the present embodiment) It is defined as the noise level of a continuous steady sound giving an average squared sound pressure equal to the average squared sound pressure of fluctuating noise in 10 seconds). The smaller the value of the equivalent noise level (L Aeq ), the less noise and the quieter. Also, the A-characteristic refers to a frequency-weighting characteristic in consideration of human hearing used in measurement by a sound level meter. The equivalent noise level (L Aeq ) of the present embodiment is measured , for example, with an A characteristic from a distance of 10 cm just beside the injection hole of the aerosol product with a normal sound level meter NL-21 (manufactured by Rion Co., Ltd.). It can be calculated. Further, the equivalent noise level (L Aeq ) in the present embodiment is a noise level when the background equivalent noise level (L Aeq ) is 36 dB. The aerosol product of the present embodiment achieves the above-mentioned equivalent noise level (L Aeq ), so that it is usually used (for example, a quiet living room etc. The background in this case is about 35 to 37 dB) ), It can be realized that the user is using it.
　本実施形態において、等価騒音レベル（ＬAeq）とバックグラウンドの騒音レベルとの差は、１５ｄＢ以上であることが好ましく、２０ｄＢ以上であることがより好ましい。等価騒音レベル（ＬAeq）とバックグラウンドの騒音レベルとの差が１５ｄＢ以上であることにより、使用者は、使用場所によらず、エアゾール組成物が充分に噴射されていることを実感できる。 In the present embodiment, the difference between the equivalent noise level (L Aeq ) and the background noise level is preferably 15 dB or more, and more preferably 20 dB or more. When the difference between the equivalent noise level (L Aeq ) and the background noise level is 15 dB or more, the user can realize that the aerosol composition is sufficiently jetted regardless of the place of use.
　また、本実施形態のエアゾール製品は、普通騒音計におけるＡ特性での噴射音の最大騒音レベル（ＬAmax）が７８ｄＢ以上であることが好ましく、８０ｄＢ以上であることがより好ましい。なお、最大騒音レベル（ＬAmax）の上限は特に限定されない。噴射時の騒音の観点から、最大騒音レベル（ＬAmax）は、１００ｄＢ以下であることが好ましい。なお、最大騒音レベル（ＬAmax）は、実測時間内の騒音レベルの最大値を表す。本実施形態の最大騒音レベル（ＬAmax）は、たとえば、普通騒音計ＮＬ－２１（リオン（株）製）にて、エアゾール製品の噴口の真横１０ｃｍの距離から、Ａ特性にて測定することにより算出することができる。また、本実施形態の最大騒音レベル（ＬAmax）は、バックグラウンドの最大騒音レベル（ＬAmax）が３６．８ｄＢである場合の騒音レベルである。 In the aerosol product of the present embodiment, the maximum noise level (L Amax ) of the injection noise in the A characteristic of the ordinary noise level meter is preferably 78 dB or more, and more preferably 80 dB or more. The upper limit of the maximum noise level (L Amax ) is not particularly limited. From the viewpoint of noise during injection, the maximum noise level (L Amax ) is preferably 100 dB or less. The maximum noise level (L Amax ) represents the maximum value of the noise level within the measurement time. The maximum noise level (L Amax ) of the present embodiment is measured, for example, with an A characteristic from a distance of 10 cm just beside the injection hole of the aerosol product with a normal sound level meter NL-21 (manufactured by Rion Co., Ltd.). It can be calculated. Further, the maximum noise level (L Amax ) in the present embodiment is the noise level when the background maximum noise level (L Amax ) is 36.8 dB.
　なお、本実施形態のエアゾール製品は、上記した原液と噴射剤との配合割合を特定し、１回あたりの噴射量を１～３ｍＬとなるよう調整し、かつ、普通騒音計におけるＡ特性での噴射音の１０秒間の等価騒音レベル（ＬAeq）が６２ｄＢ以上となるよう調整されることにより、エアゾール組成物が充分に噴射されていることを使用者が実感できる。１回あたりの噴射量を上記範囲内に調整する方法や、等価騒音レベル（ＬAeq）を調整する方法は特に限定されない。また、等価騒音レベル（ＬAeq）は、上記１回あたりの噴射量を調整する方法のほか、２５℃におけるエアゾールバルブの内圧を調整したり、原液と噴射剤との配合割合を調整したり、噴射部材の数や寸法、形状等を調整することにより、適宜調整し得る。 In the aerosol product of the present embodiment, the mixing ratio of the above-mentioned undiluted solution and propellant is specified, the injection amount per time is adjusted to be 1 to 3 mL, and the A characteristic in the ordinary noise level meter By adjusting the equivalent noise level (L Aeq ) of 10 seconds of the jet noise to be 62 dB or more, the user can realize that the aerosol composition is sufficiently jetted. There are no particular limitations on the method of adjusting the injection amount per injection within the above range or the method of adjusting the equivalent noise level (L Aeq ). The equivalent noise level (L Aeq ) can be adjusted by adjusting the internal pressure of the aerosol valve at 25 ° C, adjusting the mixture ratio of the undiluted solution and the propellant, in addition to the method of adjusting the injection amount per one time. Adjustment can be made as appropriate by adjusting the number, size, shape and the like of the ejection members.
　本実施形態のエアゾール製品の製造方法は特に限定されない。一例を挙げると、エアゾール製品は、エアゾール容器に原液を充填し、エアゾールバルブによってエアゾール容器の開口を閉止し、噴射部材の噴口またはステムを介して噴射剤を加圧充填することによって製造することができる。 The method for producing the aerosol product of the present embodiment is not particularly limited. By way of example, an aerosol product may be produced by filling the aerosol container with the undiluted solution, closing the opening of the aerosol container by means of the aerosol valve, and pressure filling the propellant through the orifice or stem of the injection member. it can.

　それぞれのエアゾール製品を有効成分としてトランスフルトリンを含んだ定量噴射型エアゾールとして８畳の室内（バックグラウンドの等価騒音レベル（ＬAeq）が３６ｄＢ）において使用させ、室内に充分に噴射されたと実感できるまで噴射させた。１回の噴射で使用実感が得られない使用者には繰り返しエアゾール組成物を噴射させ、室内に充分に噴射されたと感じるまでの噴射回数を調べた。結果を表１に示す。 (How to check the overuse prevention effect)
Each aerosol product can be used in a room of 8 tatami ( 36-dB background noise equivalent level (L Aeq ) as a fixed-injection aerosol containing transfluthrin as an active ingredient) and it can be realized that the air has been sufficiently injected into the room It was injected up to. The aerosol composition was repeatedly jetted to the user who did not get a feeling of use in one jet, and the number of jets until the user felt that the jet was sufficiently jetted into the room was examined. The results are shown in Table 1.

　表１に示されるように、実施例１、２、５、９、６８のエアゾール製品は、多くの試験者において、１回の噴射で、エアゾール組成物が室内に充分に噴射されていることを実感することができた。一方、比較例１のエアゾール製品は、エアゾール組成物が室内に充分に噴射されていることを実感するために、３～４回の噴射を要した試験者がおり、室内に充分に噴射されていることを実感するための平均噴射回数が２回であった。これらの結果より、等価騒音レベル（ＬAeq）が６２ｄＢ以上である場合（実施例１、２、５、９、６８）において、エアゾール組成物が充分に噴射されていることを使用者が実感できたことが示された。 As shown in Table 1, the aerosol products of Examples 1, 2, 5, 9, 68 show that in many testers, the aerosol composition is sufficiently injected into the room with one injection. I was able to feel it. On the other hand, in the aerosol product of Comparative Example 1, some testers required three to four injections to realize that the aerosol composition was sufficiently injected into the room, and were sufficiently injected into the room. The average number of injections to realize that it was two was. From these results, when the equivalent noise level (L Aeq ) is 62 dB or more (Examples 1, 2, 5, 9, 68), the user can realize that the aerosol composition is sufficiently injected. Was shown.

（実施例１～９１、比較例１～２８）
　表１に記載の原液処方、噴射剤の種類およびガス圧、バルブ内圧、使用したエアゾール製品の種類（エアゾール製品１～２１）を変更した以外は、実施例１と同様の方法により、エアゾール製品を調製し、等価騒音レベル（ＬAeq）（ｄＢ）および最大騒音レベル（ＬAmax）（ｄＢ）を測定した。等価騒音レベル（ＬAeq）（ｄＢ）の結果を表２に示す。最大騒音レベル（ＬAmax）（ｄＢ）の結果を表３に示す。なお、表２および表３において、ＬＰＧは液化石油ガス、ＩＰＡはイソプロピルアルコール、ＩＰＭはミリスチン酸イソプロピル、ＤＭＥはジメチルエーテルを表す。 <Confirmation of noise level and overuse prevention effect in various aerosol products>
(Examples 1 to 91, Comparative Examples 1 to 28)
An aerosol product was prepared in the same manner as in Example 1 except that the undiluted solution formulation described in Table 1, the type and gas pressure of the propellant, the valve internal pressure, and the type of aerosol product used (aerosol products 1 to 21) were changed. The equivalent noise level (L Aeq ) (dB) and the maximum noise level (L Amax ) (dB) were measured. The results of the equivalent noise level (L Aeq ) (dB) are shown in Table 2. The results of the maximum noise level (L Amax ) (dB) are shown in Table 3. In Tables 2 and 3, LPG represents liquefied petroleum gas, IPA represents isopropyl alcohol, IPM represents isopropyl myristate, and DME represents dimethyl ether.

　表２および表３に示されるように、実施例１～９１のエアゾール製品は、１回あたりの噴射量が１．０～３．０ｍＬであり、かつ、等価騒音レベル（ＬAeq）が６２ｄＢ以上であった。そのため、実施例１～９１のエアゾール製品は、種々のエアゾール組成物や噴射部材を用いた場合であっても、表１に関連して説明したように、試験者によって充分に噴射されていることを実感でき、過剰使用防止できると考えられた。また、これらの傾向は、最大騒音レベル（ＬAmax）を参照した場合も、同様であった。一方、比較例１～２８のうち、比較例１、３、５～８、１０～２４および２６～２８のエアゾール製品は、等価騒音レベル（ＬAeq）が６２ｄＢ未満であったため、試験者によって充分に噴射されていることが実感されにくく、過剰使用されやすいと考えられた。また、比較例２、４、９および２５のエアゾール製品は、等価騒音レベル（ＬAeq）が６２ｄＢ以上であったが、１回あたりの噴射量が１．０～３．０ｍＬの範囲外であったため、試験者によって充分に噴射されていることが実感されにくく、過剰使用されやすかった。したがって、試験者において充分に噴射されていることが実感されるためには、単に等価騒音レベル（ＬAeq）が６２ｄＢ以上であるかだけでなく、１回あたりの噴射量が１．０～３．０ｍＬに調整されていることも重要であることが示された。 As shown in Tables 2 and 3, the aerosol products of Examples 1 to 91 each have an injection volume of 1.0 to 3.0 mL and an equivalent noise level (L Aeq ) of 62 dB or more. Met. Therefore, the aerosol products of Examples 1 to 91 should be sufficiently sprayed by the tester as described in connection with Table 1, even when using various aerosol compositions and spraying members. Was thought to be able to prevent overuse. Also, these tendencies were similar when referring to the maximum noise level (L Amax ). On the other hand, among the comparative examples 1 to 28, the aerosol products of comparative examples 1, 3, 5 to 8, 10 to 24 and 26 to 28 had an equivalent noise level (L Aeq ) of less than 62 dB, and thus were sufficient by the tester. It was thought that it was hard to be realized that it was injected to, and it was thought that it was easy to overuse. Moreover, although the aerosol products of Comparative Examples 2, 4, 9 and 25 had an equivalent noise level (L Aeq ) of 62 dB or more, the injection amount per time was out of the range of 1.0 to 3.0 mL. Therefore, it was difficult for the tester to realize that the spray was sufficiently injected, and it was easy to overuse. Therefore, in order for the tester to realize that the injection is sufficient, not only whether the equivalent noise level (L Aeq ) is 62 dB or more, but also the injection amount per injection is 1.0 to 3 It was shown that it was also important to adjust to .0 mL.
