【０００８】
【発明の実施の形態】
以下、本発明に係るエアゾール式噴霧器の実施形態を図面を参照しながら説明する。
第１実施形態
図１乃至図４は第１の実施形態を示す。
１はエアゾール缶で、胴部２の上端部に環状突部３を周設すると共に、頂壁４中央部を貫設させて噴出用ステム５を上方付勢状態で起立する。
【０００９】
６はカバー部材で、環状突部３へ嵌着させた周壁７上面を閉塞する頂壁に、前後方向への開口部を形成して、該開口部から噴出用ステム５を突出させると共に、開口部の左右両部から側壁８を起立して、両側壁間上面を縦断面逆向きＵ字形状の頂板で閉塞する。
【００１０】
１０はトリガー付き噴霧部材で、噴出用ステム５上端へ嵌合させたステム嵌合筒１１を、前後方向へ細長の頂板１２中央部から垂設し、かつ該ステム嵌合筒１１の上端部前面から頂板１２の前半部を上壁とする射出筒１３を前方突設すると共に、頂板１２の左右両側からカバー壁１２ａを垂下する。そして、射出筒１３の前端から前方突設した支持板部１４および両カバー壁１２ａの前面からトリガー１５を垂設する。一方、頂板１２後半部の後部は、前後二重壁からなる垂下部１６を形成すると共に、該垂下部の下端部に後面開口の切欠き部１７を形成し、さらに、該切欠き部を、２つの側壁８の下方後部間に横架した揺動軸１８に回動自在に嵌合させている。
【００１１】
２０はトリガー引寄せ防止板で、周壁７の前部上端から破断可能な薄肉片を介して左右方向に長い板体を２つの側壁８の下端部間に突設して、該板体をトリガー１５の下部後面へ接触させる。
なお、２１は射出筒１３の前部内面へ嵌合させたノズルである。
【００１２】
次に本実施形態の作用について説明する。
ノズル２１から泡等を噴出させるには、トリガー１５を後方へ引き寄せればよいが、図１乃至図３に示すようにトリガー引寄せ防止板２０が除去される前の状態では該防止板２０がトリガー１５後面に接触しているため、トリガー引寄せは不能である。
【００１３】
トリガー１５の後方への引寄せを可能にするためには、トリガー引寄せ防止板２０を引っ張ってカバー部材６から除去すればよい。
除去後、トリガー１５を後方へ引き寄せると、図４に示すように頂板１２が揺動軸１８を中心にして前方へ揺動し、これと共にステム嵌合筒１１が下降して噴出用ステム５を押し下げるためノズル２１から泡等が噴出する。
【００１４】
噴出後、トリガー１５から手を離すと、噴出用ステム５が上昇して頂壁１２を後方へ揺動させることにより元の位置に復帰させる。なお、頂壁１２が元の位置よりも後方へ揺動しようとしても両側壁８間の上面を閉塞する頂板に接触するため後方への過剰の揺動は防止される。
【００１５】
第２実施形態
図５乃至図８は第２の実施形態を示す。なお、同図において、図１乃至図４と同一又は相当部分については同一符号を付すことによりその説明を省略して、相異なる点について説明する。
本実施形態では、両側壁８間上面を閉塞する頂板の後部を残して他の部分は切除すると共に、残部の頂板部分の前端下面に、頂板１２の後端部近傍部分上面を係合させる。
【００１６】
また、トリガー１５は、上記支持板部１４からではなく射出筒１３から垂下する。さらに、両側壁８の後方上端部内面に下面開口の凹部からなる軸受部２５を形成すると共に、両カバー壁１２ａ後部外面から左右方向外方に揺動軸２６を突設して、該揺動軸を軸受部２５へ回動自在に嵌合させる。さらにまた、トリガー引寄せ防止板２０は、周壁７前面から破断可能な薄肉片を介して上下方向に細長の板体を突設して、該板体の上部をトリガー１５の下部後面へ接触させる。作用についても第１の実施形態とほぼ同様であるので説明を省略する。
【００１７】
第３実施形態
図９乃至図１３は第３の実施形態を示す。なお、同図において、図１乃至図４と同一又は相当部分については同一符号を付すことによりその説明を省略して、相異なる点について説明する。
本実施形態では、頂壁１２後部を、後方へ湾曲する円弧状に形成して、該円弧状部の下端を薄肉ヒンジ２８を介して周壁７後部へ連結することにより、頂壁１２、周壁７および側壁８を一体に形成すると共に、円弧状部の下部に薄肉部２９を形成する。
【００１８】
また、ノズル３０は内外二重筒で形成して、該内外筒の間隙内に射出筒１３の前端部を嵌着させると共に、ノズル３０の外筒前端部からトリガー３１を垂設する。
さらに、請求項２記載のように、トリガー３１の上部後面から係合板３２を後方突設すると共に、両側壁８の上方前部に、係合板３２が小ストロークだけ上下動自在な切欠き部３３を形成して、該切欠き部上面に係合板３２を係合させる。
【００１９】
作用についても第１の実施形態とほぼ同様であるので説明を省略するが、本実施形態では、トリガー３１を後方へ引き寄せると、頂板１２は薄肉部２９を中心として前方へ傾斜すると共に、係合板３２は切欠き部３３の下面に係合する。一方、図１３に示すように噴出後は係合板３２が切欠き部３３上面へ係合するため、頂壁１２の後方への過剰な傾斜は防止される。
【００２０】
第４実施形態
図１４乃至図１６は第４の実施形態を示す。なお、同図において、図１乃至図４と同一又は相当部分については同一符号を付すことによりその説明を省略して、相異なる点について説明する。
本実施形態では、カバー部材６を省略して基部材３５を設ける。該基部材は、環状突部３へ嵌着させた周壁７上端に、噴出用ステム５を囲成する内向きフランジ状頂壁３６を付設すると共に、該頂壁後部から支持板３７を後方突設して、該支持板の後部上端から弾性変形自在な第１板バネ３８を起立すると共に、支持板３７後端部から左右外方に揺動軸３９を突設する。
【００２１】
また、頂板１２後部は後方へ湾曲させて、該湾曲部の中間部下面から弾性変形自在な第２板バネ４０を垂設して、該バネ下部を第１板バネ３８の上部後面へ係合させると共に、カバー壁１２ａの下端部内面に下面開口の凹部からなる軸受部４１を形成して、該軸受部に揺動軸３９を回動自在に嵌合させる。
【００２２】
さらに、トリガー引寄せ防止片４２は、内向きフランジ状頂壁３６前部から破断可能な薄肉片を介して左右方向に長い板体を起立して、該板体上端をカバー壁１２ａの前端部下端に接触させる。
さらにまた、請求項４記載のように、トリガー引き寄せ時に、２つのカバー壁１２ａの中間部下端面を内向きフランジ状頂壁３６の中央部上面へ当接自在に形成する。
【００２３】
作用についても第１の実施形態とほぼ同様であるので説明を省略するが、本実施形態では、第２板バネ４０が第１板バネ３８に係合しているため、トリガー３１を後方へ引き寄せると、トリガー付き噴霧部材１０には噴出用ステム５からの付勢力に加えて第１板バネ３８からの付勢力も作用するため、噴出後におけるトリガー付き噴霧部材１０の元の位置への復帰がより迅速化される。
【００２４】
【発明の効果】
請求項１記載の発明は、トリガーを有するため、片手でエアゾール缶を持って噴霧する場合の操作が容易である。
また、トリガー引寄せ防止板を有するため、消費者の手元に届くまでの間に、或いは実際に使用するまでの間に、誤って噴霧されることがない。
【００２５】
また請求項１記載の発明は、係合板を切欠き部へ係合させたので、噴霧後、トリガーが元の位置よりも上がり過ぎることがない。
【００２６】
請求項２記載の発明は、第２板バネを第１板バネへ係合させたので、噴出後におけるトリガー付き噴霧部材の復帰動作の迅速化が可能になる。請求項３記載の発明は、トリガー引寄せ時に、カバー壁下端が内向きフランジ状頂壁へ当接可能に形成したので、噴出用ステムが過度に押し込まれることがない。

On the other hand, as shown in FIG. 13, since the engaging plate 32 engages with the upper surface of the notch 33 after ejection, excessive inclination of the top wall 12 to the rear is prevented.
[0020]
Fourth embodiment Fig. 14 to Fig. 16 show a fourth embodiment. In the figure, the same or corresponding parts as those in FIGS. 1 to 4 are denoted by the same reference numerals, and the description thereof will be omitted, and different points will be described.
In this embodiment, the cover member 6 is omitted and the base member 35 is provided. The base member is provided with an inwardly flanged top wall 36 surrounding the ejection stem 5 at the upper end of the peripheral wall 7 fitted to the annular protrusion 3, and the support plate 37 protrudes backward from the rear part of the top wall. The first plate spring 38 that is elastically deformable is erected from the rear upper end of the support plate, and the swing shaft 39 projects from the rear end of the support plate 37 to the left and right.
[0021]
Further, the rear portion of the top plate 12 is bent rearward, and a second leaf spring 40 that is elastically deformable is suspended from the lower surface of the middle portion of the bending portion, and the lower portion of the spring is engaged with the upper rear surface of the first leaf spring 38. At the same time, a bearing portion 41 formed of a recess having a lower surface opening is formed on the inner surface of the lower end portion of the cover wall 12a, and the swing shaft 39 is rotatably fitted to the bearing portion.
[0022]
Furthermore, the trigger pulling prevention piece 42 stands upright in the left-right direction through a thin piece that can be broken from the front portion of the inward flange-like top wall 36, and the upper end of the plate body is set to the front end portion of the cover wall 12a. Touch the bottom.
Furthermore, as described in claim 4, when the trigger is pulled, the lower end surfaces of the intermediate portions of the two cover walls 12a are formed so as to be able to contact the upper surface of the central portion of the inwardly flanged top wall 36.
[0023]
Since the operation is almost the same as that of the first embodiment, the description thereof will be omitted. However, in this embodiment, since the second leaf spring 40 is engaged with the first leaf spring 38, the trigger 31 is pulled backward. Since the urging force from the first leaf spring 38 acts on the spray member with trigger 10 in addition to the urging force from the ejection stem 5, the trigger-equipped spray member 10 is restored to its original position after ejection. It will be faster.
[0024]
【The invention's effect】
Since the invention of claim 1 has a trigger, the operation when spraying with an aerosol can with one hand is easy.
Moreover, since it has a trigger attraction prevention plate, it does not accidentally spray before reaching the consumer's hand or before actually using it.
[0025]
In the first aspect of the invention, since the engaging plate is engaged with the notch, the trigger does not rise too much from the original position after spraying.
[0026]
According to the second aspect of the present invention, since the second leaf spring is engaged with the first leaf spring, it is possible to speed up the return operation of the spray member with a trigger after ejection. According to the third aspect of the present invention, since the lower end of the cover wall is formed so as to be able to come into contact with the inwardly flanged top wall when the trigger is pulled, the ejection stem is not excessively pushed.
