Description

【０００１】
【発明の属する技術分野】
本発明は、一体に連結した複数のエアゾール缶へ装着させるエアゾール缶スパウトに関する。
【０００２】
【従来の技術】
缶上面を閉塞する頂壁を貫通させて、液体噴出用ステムを上方付勢させて起立する、異種液体を収納する一対のエアゾール缶と、両エアゾール缶を胴部を接して一体的に緊縛する緊縛部材と、両エアゾール缶の上部外面へ第１頂板外周から垂下する第１周壁を嵌着させると共に、第１頂板外周から、左右方向中間の前後両壁部分を開放させて第２周壁を起立し、かつ第２周壁の上端開口面を閉塞する第２頂板を、第２周壁上端面へ載置させて後方突出し、更に第２頂板前部の左右方向へ第２薄肉ヒンジを、かつ第２周壁内方の左右両側部に、第２薄肉ヒンジ両端から第２頂板後端まで切離し線を穿設して、押下げ板を形成し、更に又、ステム起立位置に対応する第１頂板部分を開口するキャップ部材と、ステムの上端部外面へ下端部を嵌着させて起立する基筒部上端から第２周壁の前壁開放部分内を通って水平筒部を前方突出し、これら両水平筒部を前上方からみてＶ字状に前端を近接させて弾性片で一体に連結したノズル部材とからなり、押下げ板の後端部押下げでノズル部材を介して両ステムが下降可能に形成したエアゾール式の二液混合容器が知られている（例えば、特開平１１−２７８５５４号公報参照）。
【０００３】
【発明が解決しようとする課題】
製品間の寸法のバラツキにより、エアゾール缶の高さ、特にエアゾール缶内でポンプピング作用する噴出用ステムの高さがエアゾール缶の相互間で微小ながら相異なっているのが通常である。このため一対のエアゾール缶を連結して二液混合容器として使用する場合に、押下げ板を押し下げると、高い方のステムが先に押下げられて缶内でポンピングするため、まず一方のエアゾール缶の液体のみが噴霧される。
【０００４】
この状態からさらに押下げ板を押下げれば、続いて低い方のステムが押し下げられるため、これによって二液混合状態で噴霧されることとなり問題はないが、高い方のステムのみが押下げられて噴霧した時点を通常の二液混合による噴霧状態と錯誤して、その位置を保持した状態で噴霧を継続することがある。
【０００５】
特に、二液混合容器をはじめて使用する使用者は噴霧量との関係で押下げ板の押下げ加減が分からないため、ゆっくりと押下げ板を押し下げる傾向があり、上記のような錯誤に陥る可能性が高かった。
【０００６】
請求項１に係る発明は、各噴出用ステムをほぼ同時に押下げ可能にすることを目的とする。
【０００７】
請求項２に係る発明は、請求項１に係る発明が有する解決課題を有するほか、構成の簡素化を図ることを目的とする。
【０００８】
請求項３に係る発明は、請求項２に係る発明が有する解決課題を有するほか、各噴出用ステムが押し下げられたことを感触のみらず視覚によっても確認可能とすることを目的とする。
【０００９】
請求項４に係る発明は、請求項２に係る発明が有する解決課題を有するほか、弾性板が係合部から外れたことを押し加減の感触で確認可能とすることを目的とする。
【００１０】
請求項５に係る発明は、請求項２に係る発明が有する解決課題を有するほか、各噴出用ステムが押し下げられたことを感触のみらず視覚によっても確認可能とすることを目的とする。
【００１１】
請求項６に係る発明は、請求項２乃至請求項５に係る発明が有する解決課題を有するほか、各噴出用ステムが押し下げられたことが感触や視覚のみならず聴覚によっても確認可能にすることを目的とする。

【００２０】
【発明の実施の形態】
以下の説明において、便宜上、図１の左右方向を前後方向と定める。
同図において、１はエアゾール缶で、胴部上面を閉塞する頂壁へ噴出用ステム２を上方付勢状態で貫設させている。図２に示すようにエアゾール缶は２本使用し、これらを胴部接触状態で左右に配置する。
【００２１】
３はアダプタで、周壁を２本のエアゾール缶の上端部外面へ嵌着させることで両缶を一体的に連結している。
４はカバー部材で、周壁５の下部をアダプタ３外面へ嵌着させると共に、周壁５上部の前後両部に第１および第２切欠部６、７を形成している。
【００２２】
８はノズル部材で、底壁９から２つの連結筒１０を垂設し、かつこれら連結筒下部を各噴出用ステム２の上部外面へ嵌合させ、かつ底壁９外面へ着脱自在に嵌合させた上面閉塞の周壁１１の前面から２つの噴出筒１２を前方突設すると共に、周壁１１の後部下端を底壁９の後部へ薄肉ヒンジ１３を介して連結させている。
【００２３】
１４はステム押下げ用の操作板で、カバー部材４の周壁５の上端部内面を閉塞し、かつ第１切欠部６の上部内へ前部を嵌合させて嵌合板部１５ａに形成すると共に、第２切欠部７の上部内へ後部を遊嵌させて上下動板部１５ｂに形成した板体１５を有し、嵌合板部１５ａから垂下板１７を第１切欠部６内へ嵌着させて垂設し、その垂下板１７下部に噴出筒１２を挿通させる切欠きを形成している。
【００２４】
また、板体１５の中央部に、一部を弾性復帰用の板バネ１８として残して形成した楕円形状の切離線１９の両端を上下動板部１５ｂ基端の左右両部へ連設して押下げ板２０を形成している。
さらに、図４および図５に明示するように、押下げ板２０下面から下斜め後方へ傾斜する左右一対の操作板用板バネ２１を突設して、これら板バネの先端部をノズル部材の周壁１１の頂板へ圧接させている。なお、上下動板部１５ｂの後部から後述する垂下板２５を垂設する。
【００２５】
２２は操作板規制手段で、図３に明示するように、第２切欠部７下面の中央部内縁から外縁を通ってカバー部材の下方へ伸びる２本の割溝２３間のカバー部材部分で形成する弾性板２４と、操作板１４の上下動板部１５ｂ後端から垂設する垂下板２５の下部外面に形成された下向き段部からなる係合部２６とで形成され、かつ弾性板２４の先端部を係合部２６下面へ係合させている。
【００２６】
次に作用について説明する。
２液混合液を噴出筒１２から噴出させるには、操作板用板バネ２１の付勢力に抗して操作板１４を押し下げればよいが、垂下板２５の係合部２６には弾性板２４が係合しているため一定以上の押下げ力が必要である。この押下げにより、弾性板２４が後方へ弾性変形して係合部２６との係合から離脱すると、押下げ力がノズル部材８に一気に加わるため、噴出用ノズル２の高さに微小の違いがあっても２つの噴出用ステムはほぼ同時に押し下げられる。
【００２７】
噴出後、ノズル部材８は噴出用ステム２の上方付勢力で上昇すると共に、垂下板２５は操作板用板バネ２１と弾性復帰用の板バネ１８との弾性力で元の形状に復帰し、同時に弾性板２４の先端部が垂下板２５の係合部２６下面へ係合する。
【００２８】
図６ないし図１０は本発明の第２の実施形態を示す。なお、図６は第２実施形態におけるエアゾール缶スパウトの背面図である。
本実施形態では、操作板規制手段２２を構成する弾性板３０は、請求項４に記載のように、操作板１４の後端部下面から左右方向へ突設する２つの弾性片で形成する。また係合部３２は第２切欠部７の左右両側面の上端部に形成した突起で形成し、かつ該突起を弾性板３０よりもやや下方に位置させておく。その他の構成は第１の実施形態と同一であるから説明を省略する。
【００２９】
次に作用について説明する。
噴出のために、操作板１４を押し下げると、弾性板３０が図９に示す位置から下降して図１０に点線で示すように係合部３２へ係合して、上方に弾性変形することで係合部３２を乗り越える。乗り越えることで押下げ力がノズル部材８に一気に加わるため、噴出用ノズル２の高さに微小の違いがあっても２つの噴出用ステムはほぼ同時に押し下げられること第１の実施形態と同様である。
【００３０】
図１１ないし図１４は第３の実施形態を示す。なお、図１１は第３実施形態におけるエアゾール缶スパウトの背面図である。
本実施形態では、操作板規制手段２２を構成する弾性板４０は、請求項５に記載のように、第２切欠部７下面の左端ないし右端の一方から起立して下方へ湾曲する板バネで形成すると共に、係合部４１を、操作板１４の後端部下面に形成した突起で形成する。そして図示例のように弾性板４０を第２切欠部７下面の左端から起立させる場合には弾性板４０先端部を係合部４１の右側へ圧接させ、逆に右端から起立させる場合には、板４０先端部を係合部４１の左側へ圧接させる。その他の構成は第１の実施形態と同一であるから説明を省略する。
【００３１】
次に作用について説明する。
操作板１４を押し下げると、図１４に示すように、弾性板４０の先端部に右方向への力が作用するため、弾性板先端部が係合部４１を乗り越えて、係合部４１から右方向へ離脱する。乗り越えることで押下げ力がノズル部材８に一気に加わるため、噴出用ノズル２の高さに微小の違いがあっても２つの噴出用ステムはほぼ同時に押し下げられること第１の実施形態と同様である。
噴出後、操作板１４が上昇すると、弾性板４０は弾性力により元の形状に復帰し、その際、弾性板４０先端部が係合部４１を乗り越えて、該係合部の左側に位置する。
【００３２】
なお、請求項６に記載のように、上記いずれの実施形態においても操作板１４の押下げで、操作板規制手段を構成する弾性板と係合部との係合が外れる際に、カチッというクリック音が発生するように材質を選定するのが好ましい。
【００３３】
【発明の効果】
請求項１に係る発明は、操作板の押下げによる噴出用ステムのほぼ同時的押下げを可能とする操作板規制手段を設けたので、エアゾール缶や噴出用ステムの高さに微小な不揃いがあっても各ステムは必ずほぼ同時に押し下げられるため、従来例のように高い噴出用ステムのみが押し下げられるというようなことはなく、よってエアゾール缶を複数連設する趣旨が没却されることがない。
【００３４】
請求項２に係る発明は、操作板規制手段を、弾性板と係合部とで形成するため、構成の簡素化を図ることができる。
【００３５】
請求項３に係る発明は、操作板の押下げ時に、弾性板が係合部から外れて外方へ弾性変形するため、各噴出用ステムが押し下げられたことが感触のみらず視覚によっても確認することができる。
【００３６】
請求項４に係る発明は、弾性板が係合部から外れたことを押し加減の感触で認識することができる。
【００３７】
請求項５に係る発明は、弾性板が係合部から外れると、弾性板が一方周方向へ弾性変形するため、各噴出用ステムが押し下げられたことを感触のみらず視覚によっても確認することができる。
【００３８】
請求項６に係る発明は、弾性板が係合部から外れる際に、クリック音が発生可能に設けたので、各噴出用ステムが押し下げられたことが感触や視覚のみならず聴覚によっても確認することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an aerosol can spout to be attached to a plurality of integrally connected aerosol cans.
[0002]
[Prior art]
A pair of aerosol cans that contain different types of liquid, standing up by penetrating the top wall that closes the top surface of the can and energizing the stem for ejecting the liquid upward, and the two aerosol cans are integrally bound to each other by contacting the body. The first peripheral wall hanging from the outer periphery of the first top plate is fitted to the upper outer surface of both the binding member and the aerosol cans, and the second peripheral wall is erected from the outer periphery of the first top plate by opening both the front and rear wall portions in the middle in the left-right direction. And a second top plate that closes the upper end opening surface of the second peripheral wall is placed on the upper end surface of the second peripheral wall and protrudes rearward, and further a second thin hinge is formed in the left-right direction of the front portion of the second top plate, and the second On both the left and right sides inside the peripheral wall, a separation line is formed from both ends of the second thin hinge to the rear end of the second top plate to form a push-down plate. Further, the first top plate portion corresponding to the stem standing position is formed. The lower end is fitted to the cap member that opens and the outer surface of the upper end of the stem. The horizontal cylinder part protrudes forward from the upper end of the base cylinder part standing up through the front wall opening part of the second peripheral wall, and both horizontal cylinder parts are seen from the front upper side, and the front ends are brought close to each other and integrated with an elastic piece. There is known an aerosol-type two-component mixing container which is formed by a nozzle member connected to the lower end of the pressing plate and is formed so that both stems can be lowered via the nozzle member by pressing the rear end of the pressing plate (see, for example, Japanese Patent Laid-Open No. Hei 11). No. -278554).
[0003]
[Problems to be solved by the invention]
Due to the dimensional variation between products, the height of aerosol cans, particularly the height of the ejection stem that pumps in the aerosol cans, is usually slightly different between the aerosol cans. For this reason, when a pair of aerosol cans are connected and used as a two-component mixing container, when the push-down plate is pushed down, the higher stem is pushed down first and pumped in the can. Only the liquid is sprayed.
[0004]
If the push-down plate is further pushed down from this state, the lower stem will be pushed down, and this will cause spraying in a two-component mixed state, but there is no problem, but only the higher stem is pushed down. The spraying time may be mistaken for the normal spraying state by two-component mixing, and spraying may be continued with the position maintained.
[0005]
In particular, users who use a two-component mixing container for the first time do not know whether or not the push plate is pushed down in relation to the amount of spray, so there is a tendency to push down the push plate slowly. The nature was high.
[0006]
An object of the invention according to claim 1 is to enable the ejection stems to be pushed down almost simultaneously.

[0010]
The invention according to claim 5 has the problem to be solved by the invention according to claim 2, and is intended to make it possible not only to feel but also to visually confirm that each ejection stem is pushed down.
[0011]
The invention according to claim 6 has the problems to be solved by the inventions according to claims 2 to 5 and makes it possible to confirm that each ejection stem is depressed not only by touch and visual sense but also by hearing. With the goal.

In the figure, reference numeral 1 denotes an aerosol can, and an ejection stem 2 is provided in an upwardly biased state on a top wall that closes the upper surface of the body portion. As shown in FIG. 2, two aerosol cans are used, and these are arranged on the left and right with the trunk contacting.
[0021]
Reference numeral 3 denotes an adapter which integrally connects the two cans by fitting the peripheral wall to the outer surfaces of the upper ends of the two aerosol cans.
Reference numeral 4 denotes a cover member. The lower portion of the peripheral wall 5 is fitted to the outer surface of the adapter 3, and first and second cutout portions 6 and 7 are formed at both front and rear portions of the upper portion of the peripheral wall 5.
[0022]
Reference numeral 8 denotes a nozzle member. Two connecting cylinders 10 are suspended from the bottom wall 9, and the lower parts of these connecting cylinders are fitted to the upper outer surface of each ejection stem 2 and are detachably fitted to the outer surface of the bottom wall 9. Two ejection cylinders 12 are projected forward from the front surface of the peripheral wall 11 with the upper surface closed, and the rear lower end of the peripheral wall 11 is connected to the rear part of the bottom wall 9 via a thin hinge 13.
[0023]
14 is an operation plate for pressing the stem, which closes the inner surface of the upper end portion of the peripheral wall 5 of the cover member 4 and fits the front portion into the upper portion of the first cutout portion 6 to form the fitting plate portion 15a. The plate 15 is formed in the up-and-down moving plate portion 15b by loosely fitting the rear portion into the upper portion of the second cutout portion 7, and the hanging plate 17 is fitted into the first cutout portion 6 from the fitting plate portion 15a. A notch through which the ejection cylinder 12 is inserted is formed in the lower part of the hanging plate 17.
[0024]
Further, both ends of an elliptical separation line 19 formed by leaving a part of the plate 15 as a plate spring 18 for elastic recovery are connected to both the left and right portions of the base end of the vertical moving plate 15b. A pressing plate 20 is formed.
Further, as clearly shown in FIGS. 4 and 5, a pair of left and right operation plate leaf springs 21 inclined obliquely downward and rearward from the lower surface of the push-down plate 20 are provided so as to project the tip portions of these plate springs to the nozzle member. It is brought into pressure contact with the top plate of the peripheral wall 11. A hanging plate 25, which will be described later, is suspended from the rear portion of the vertical moving plate portion 15b.

[0026]
Next, the operation will be described.
In order to eject the two-liquid mixture from the ejection cylinder 12, the operation plate 14 may be pushed down against the urging force of the operation plate leaf spring 21, but the engaging plate 26 of the drooping plate 25 has an elastic plate 24. Because of the engagement, a certain level of pressing force is required. When the elastic plate 24 is elastically deformed rearward by this pressing and is disengaged from the engagement with the engaging portion 26, the pressing force is applied to the nozzle member 8 at a stroke, so that the height of the ejection nozzle 2 is slightly different. The two ejection stems are pushed down almost simultaneously.
[0027]
After the ejection, the nozzle member 8 is raised by the upward biasing force of the ejection stem 2, and the hanging plate 25 is restored to its original shape by the elastic force of the operation plate leaf spring 21 and the elastic return leaf spring 18, At the same time, the tip of the elastic plate 24 engages with the lower surface of the engaging portion 26 of the hanging plate 25.

The engaging portion 32 is formed by a protrusion formed at the upper end portions of the left and right side surfaces of the second notch portion 7, and the protrusion is positioned slightly below the elastic plate 30. Since other configurations are the same as those of the first embodiment, description thereof is omitted.
[0029]
Next, the operation will be described.
When the operation plate 14 is pushed down for ejection, the elastic plate 30 descends from the position shown in FIG. 9 and engages with the engaging portion 32 as indicated by the dotted line in FIG. Get over the engaging portion 32. Since the pressing force is applied to the nozzle member 8 at a stretch by getting over, the two ejection stems are pushed down almost simultaneously even if there is a slight difference in the height of the ejection nozzle 2, as in the first embodiment. .

At the same time, the engaging portion 41 is formed by a protrusion formed on the lower surface of the rear end portion of the operation plate 14. When the elastic plate 40 is erected from the left end of the lower surface of the second notch 7 as shown in the illustrated example, the elastic plate 40 is pressed against the right side of the engaging portion 41 and vice versa. The front end of the plate 40 is pressed against the left side of the engaging portion 41. Since other configurations are the same as those of the first embodiment, description thereof is omitted.
[0031]
Next, the operation will be described.
When the operation plate 14 is pushed down, as shown in FIG. 14, a force in the right direction acts on the tip of the elastic plate 40, so that the tip of the elastic plate gets over the engaging portion 41 and moves to the right from the engaging portion 41. Leave in the direction. Since the pressing force is applied to the nozzle member 8 at a stretch by getting over, the two ejection stems are pushed down almost simultaneously even if there is a slight difference in the height of the ejection nozzle 2, as in the first embodiment. .
When the operation plate 14 rises after the ejection, the elastic plate 40 returns to its original shape by the elastic force, and at this time, the distal end portion of the elastic plate 40 gets over the engaging portion 41 and is positioned on the left side of the engaging portion. .
[0032]
In any of the above embodiments, when the operation plate 14 is pushed down, the elastic plate constituting the operation plate restricting means and the engagement portion are disengaged by clicking. The material is preferably selected so that a click sound is generated.
[0033]
【The invention's effect】
Since the invention which concerns on Claim 1 provided the operation-plate control means which enables substantially the simultaneous depression of the ejection stem by pushing down of the operation plate, there is a minute irregularity in the height of the aerosol can and the ejection stem. Even if there is, each stem is always pushed down almost at the same time, so there is no such thing as pushing down only the high ejection stem as in the conventional example, and therefore the purpose of connecting a plurality of aerosol cans is not lost. .
[0034]
In the invention according to claim 2, since the operation plate restricting means is formed by the elastic plate and the engaging portion, the configuration can be simplified.
[0035]
In the invention according to claim 3, when the operation plate is pushed down, since the elastic plate is detached from the engaging portion and elastically deforms outward, it is confirmed not only by touch but also visually that each ejection stem is pushed down. can do.
[0036]
In the invention according to claim 4, it is possible to recognize that the elastic plate is disengaged from the engaging portion with a pressing feeling.
[0037]
In the invention according to claim 5, when the elastic plate is detached from the engaging portion, the elastic plate is elastically deformed in one circumferential direction, so that it is confirmed not only by touch but also visually that each ejection stem is pushed down. Can do.
[0038]
The invention according to claim 6 is provided so that a click sound can be generated when the elastic plate is disengaged from the engaging portion, so that it is confirmed by hearing as well as touch and sight that each ejection stem is pushed down. be able to.
[0039]
In the invention according to claim 7, since the plate spring is provided on the operation plate, the elastic return of the operation plate can be performed quickly.
