Description
例えば特許文献1等で公知のノズルは、1対の相対位置を固定されたエアゾール容器から突出している2本のステムに嵌着する噴出ヘッドを有しており、この噴出ヘッドの上部に配置されたレバーを押し下げることで、噴出ヘッドごとステムを押し下げ、ステムを介してエアゾール容器内から流出した2種類の内容物が噴出ヘッド内で混合された後、ノズル外に噴射される。
また、特許文献2等で公知のノズルは、1対の相対位置を固定されたエアゾール容器から突出している2本のステムに嵌着するジョイント部材と、ジョイント部材に嵌合するカバー部材によって形成された流路を有しており、カバー上部を押し下げることで、ステムは押し下げられ、ステムを介してエアゾール容器内から流出した2種類の内容物が流路内の混合室で混合された後、ノズル外に噴射される。
混合を均一にするために、撹拌室、混合室の構造をさらに工夫することも考えられるが、部品点数が多くなったり、複雑な構造となり、製造や組立のコストが大きくなるという問題があった。
また、流路や撹拌室、混合室の容量が大きいため、噴射後に流路内に残る内容物が多く、ノズル外に流出し、缶胴や手、衣服などを汚す虞があった。
また、残留した内容物が固化して、次の噴射が正常に行えなかったり、変質したり雑菌が繁殖した内容物が混じった状態で噴射されてしまう危険性があった。
噴射後に流路内に残る内容物を減らすために、分解して洗浄することも考えられるが、使用者の手間が増えるとともに、洗浄分の内容物が無駄になるという問題があった。
また、合流溝の形状、深さ等に応じて、内容物の種類や性質、使用用途に応じた様々な形状の合流流路を形成することが容易であり、複数の内容物を均一に混合して噴射することが可能となる。
さらに、合流溝の形状、深さを、均一に混合可能な小さな容量の合流流路に形成することができ、噴射後に流路内に残る内容物を少なくすることが可能となる。
本請求項3に記載の構成によれば、複数の合流流路が、形状の異なるものを含むことにより、複数の内容物の種類や性質が異なる場合でも、均一に混合して噴射することが可能となる。
本請求項4に記載の構成によれば、下部当接面と上部当接面の少なくとも一方には、複数の合流流路と混合流路をつなぐ混合空間が形成されていることにより、混合空間内で複数の内容物を均一に混合することができる。
また、混合空間を混合流路直下に設けることで小さな容量とすることができるため、噴射後に流路内に残る内容物も少なくすることができる。
本請求項5に記載の構成によれば、ノズル上部とノズル下部とが、一体成型され、ヒンジ部で連結されていることにより、さらに製造や組立のコストを低減することが可能となる。

ノズル下部120は、2つのステム103にそれぞれ嵌合するステム嵌合部121と、上部当接面122と、上部当接面122に開口しステム嵌合部121から貫通するステム連通流路123と、ステム連通流路123の開口を一直線につなぐ合流溝126と、上部当接面122の周囲を囲む内周嵌合凹部125と、内周嵌合凹部125の周囲を囲む外周嵌合凸部124とを有している。
また、ノズル下部120とノズル上部110とは、上部当接面122と下部当接面112とが密着するように嵌合することで、合流溝126の上方を下部当接面112が塞ぎ、ステム連通流路123の開口と混合流路111の開口とを一直線上につなぐ合流流路131を形成する。
エアゾール用のノズル100は、エアゾール容器101から突出した2つのステム103にステム嵌合部121を嵌合させた状態に配置されている。
エアゾール用のノズル100の押圧部118を下方に押し込むと、2つのステム103が押し下げられ、2つのステム103のそれぞれのバルブ機構が同時に開放され、エアゾール容器101内に充填されている噴射剤の圧力によって、エアゾール容器101内の内容物がステムを通過し、エアゾール用のノズル100内へ流入する。
エアゾール用のノズル100のノズル下部120とノズル上部110とは、内周嵌合凹部125に内周嵌合凸部114が圧入嵌合され、外周嵌合凹部113に外周嵌合凸部124が圧入嵌合され、上部当接面122と下部当接面112の周囲を囲んでいるため、万一、内容液が上部当接面122と下部当接面112との間に浸出した場合でも、エアゾール用のノズル100の噴口117以外から漏出することはない。
また、流路内容積を小さく形成しているため、内容物噴射後にエアゾール用のノズル100内に残留する内容物の量を少なくでき、噴口117から内容物が漏出する虞を軽減できる。
以下の実施形態において、第1実施形態と共通する点は省略して説明する。
このことで、混合空間132において内容物に回転流が発生し、混合流路111内を通過しながらの混合がさらに促進される。
また、上部当接面122には、混合流路111の開口の下方にあたる部分に、混合空間132を形成しており、2つの合流溝126cは、それぞれのステム連通流路123の接線とは別に、混合空間132の接線を内壁に持つ。
このことで、第2実施形態と同様に混合空間132において内容物に回転流が発生し、混合流路111内を通過しながらの混合がさらに促進される。
また、2つの合流溝126dは、互いに交差することがなく、それぞれのステム連通流路123と混合流路111の開口をつなぐように配置されている。
また、上部当接面122には、混合流路111の開口の下方にあたる部分に、混合空間132を形成しており、2つの合流溝126dの内壁は、それぞれのステム連通流路123と混合空間132との共通の接線を有している。
このことで、合流溝126dは混合空間132に向かって断面積が小さくなり、通過する内容物の流速が大きくなるため、混合空間132における回転流をさらに速いものとし、混合流路111内を通過しながらの混合がさらに促進される。
また、合流溝126eは、第1実施形態の合流溝126を、ステム連通流路123の開口の略半分ずらした位置まで、混合流路111の中心軸を回転軸として時計回りに回転させた位置関係で形成されている。
混合空間を設けることなく、回転流が混合流路111内に発生し、通過しながらの混合が促進される。
このことで、それぞれの合流溝126f、126f’の幅を適宜選択することで、混合する2つの内容物の混合比を1:1以外に設定したい場合や、2つの内容物の粘性等が異なる場合にも対応することが可能となる。
このことで、合流溝126gは混合流路111に向かって断面積が小さくなり、通過する内容物の流速が大きくなるため、混合流路111内を通過しながらの混合がさらに促進される。
また、2つの合流溝126h及び126h’は互いに交差することがなく、それぞれのステム連通流路123と混合流路111の開口を一直線につなぐように配置されている。また、合流溝126h及び126h’は、互いに異なるステム連通流路123に接続され、他方のステム連通流路123に向かうに従って溝の深さが浅くなるように形成されている。
このことで、合流溝126hは混合流路111に向かって断面積が小さくなり、通過する内容物の流速が大きくなるとともに、混合空間を設けることなく、回転流が混合流路111内に発生し、通過しながらの混合が促進される。
合流溝126iは、合流溝126i’よりも溝の深さが浅く形成されており、上部当接面122には、混合流路111の開口の下方にあたる部分に、混合空間132を形成している。
また、ノズル上部110iの下部当接面112には、合流溝126i’に嵌合可能な合流流路凸部115を有しており、ノズル上部110iとノズル下部120iとが嵌合することで、合流流路131は、合流溝126i側と合流溝126i’側とで、流路断面積が等しく、段差のある流路を形成する。
このことで、混合空間132において内容物に上下方向の回転流が発生し、混合流路111内を通過しながらの混合がさらに促進される。
ノズル下部120jとノズル上部110jとを嵌合した際には、前述した各実施形態と同様に、ステム連通流路の開口と混合流路の開口とをつなぐ複数の合流流路が形成され、その形態は、前述した各実施形態のものを含め、いかなるものであってもよい。
本実施形態に係るノズル100jは、ノズル100jの押下接触部119に接触して押圧可能なレバー(図示しない)を有するカバー部材(図示しない)に適用することで、レバーを押し下げてノズル100jの押下接触部119を押圧し、内容物を噴射可能となる。
このことで、ノズル100jの形状を変更することなく、エアゾール製品上部の外観をカバー部材によって自由に変更可能であり、また、レバー押下方式でのノズル100jの押圧によって、ノズル100jを介して2つのステム103を均等に押圧でき、2液の同時噴射性がさらに向上される。
例えば、上述した実施形態のエアゾール用のノズルは、エアゾール容器から2つのステムが突出しているものに装着するものであるが、ステムの数は2つに限定されず、ステムの数とそれぞれのステムの突出位置に対応したステム嵌合部を設け、それぞれに対応した合流溝を有するエアゾール用のノズルを適宜用意すればよく、ステムの数が3本以上突出していてもよい。
また、上述した実施形態のエアゾール用のノズルは、2つのステムが突出した1本のエアゾール容器に装着するものであるが、エアゾール容器の数は1本に限定されず、ステムが1本あるいは複数本突出したエアゾール容器を複数本並べたものに装着するものであってもよい。
また、上述した実施形態のエアゾール用のノズルは、合流溝がノズル下部の上部当接面に設けられるものであるが、合流溝をノズル上部の下部当接面に設けてもよく、下部当接面と上部当接面の両方に設けてもよい。
また、上述した実施形態のエアゾール用のノズルは、合流溝が略直線で形成されているものであるが、合流溝の形状は直線に限定されず、例えば、それぞれのステム連通流路から混合流路まで弧を描くような形状でもよく、屈曲した形状や、蛇行した形状でもよい。
また、上述した実施形態のエアゾール用のノズルは、それぞれのステム連通流路に接続している合流溝は一本であるものであるが、合流溝の接続数は一本に限定されず、例えば、1つのステム連通流路に2本の合流溝が接続されていてもよい。
また、上述した実施形態のエアゾール用のノズルは、ノズル上部とノズル下部とを別部品であるが、ノズル上部とノズル下部はヒンジ等で連結された一体成型品であってもよい。
また、上述した実施形態のエアゾール用のノズルは、2本のステムは互いに略同じ高さで位置固定されるものであるが、2本のステムの固定位置は互いに同じ高さでなくてもよく、例えば、固定される高さの異なる2本のステムに対応する、高さの異なるステム嵌合部を有したノズル下部を用いてもよい。
