Definitions
- the present invention relates to a two-liquid discharge product.
- aerosol products contain the contents and the propellant in the same space, and discharge them at the same time, and the contents and the propellant in separate and independent spaces. Some of them discharge the contents by contracting the space in which the objects are stored.
- the latter aerosol product is known as a double aerosol container including a pressure vessel, a flexible inner bag housed in the pressure vessel, and an aerosol valve that closes the pressure vessel and the inner bag.
- This double aerosol container is filled with a propellant or contents in the space between the pressure vessel and the inner bag, and the contents and the propellant are filled in the inner bag, thereby making the contents and the injection member independent. And store it. Then, by opening the valve, the propellant presses the inner bag, and only the contents are discharged.
- Patent Document 1 there is a two-liquid discharge product that is equipped with an inner bag that can divide and fill two contents and discharge two liquids simultaneously.
- FIG. 1 of Patent Document 1 divides one inner bag into an upper chamber and a lower chamber, and each is filled with contents

Further, since the first contents and the second contents are not adjacent to each other, even if any of the contents is highly permeable, it cannot move to the other unless it is through the propellant, and the durability is high. Moreover, since the pouch which consists of a sheet
- the inner container when the inner container has substantially the same shape as the inner surface of the pressure vessel, the first space is almost completely eliminated by being pressed by the propellant on the inner surface side of the pressure vessel. It is possible to reduce the remaining amount of the second content as much as possible.

カバー26は、ハウジング21を覆う円筒状のカバー部26aと、ハウジング21のフランジ部28aと耐圧容器11のフランジ部11eを挟むようにして、耐圧容器11のフランジ部11eの下面に対してカシメる固定部26bとを有する。カバー部26aの天面には、ステム22を通す中心孔26cが形成されている。
噴射剤Pとしては、窒素、圧縮空気、炭酸ガス、亜酸化窒素などの圧縮ガス、液化石油ガス、ジメチルエーテル、ハイドロフルオロオレフィンなどの液化ガスなどがあげられる。
他の製造方法としては、二層構造のパリソンからブロー成型することによって耐圧容器11と中容器12とを一緒に成型し、次いで、パウチ13を装着したバルブアッセンブリ14を中容器12内に挿入する。このとき中容器12とバルブアッセンブリ14の間(詳しくは、耐圧容器11とハウジング21の間から中容器12とハウジング21を介して)から第2空間S2に噴射剤Pを充填し、この噴射剤Pの充填と同時あるいは充填直後に、カバー26の固定部26bの下端をカシメて、バルブアッセンブリ14を耐圧容器11に固定し、第1空間S1および第2空間S2を密封する。その後、ステム22を下降させ、第1空間S1およびパウチ13の空気を排出する。最後に、第1空間S1に連通する第2ステム内通路31bから第2内容物A2を充填し、パウチ13に連通する第1ステム内通路31aステム22の通路から第1内容物A1を充填する。
パウチ43は、図1のパウチ13と実質的に同じものである。
ステム52、第1ステムラバー53、第2ステムラバー54、バネ56は、図1のバルブアッセンブリ14と実質的に同じものである。
保持部材55は、筒状のものであり、第1ステムラバー53と第2ステムラバー54との間に設けられ、ステム52を押し下げたときに第1ステムラバー53と第2ステムラバー54が安定した形状に撓むように保持するものである。また、側連通孔51fと保持部材55内とを連通するように側面には、貫通孔55aが形成されている。
カバー57は、バルブ保持部57a、バルブホルダーを覆う円筒状のカバー部57bと、バルブホルダーのフランジ部46bと耐圧容器11のフランジ部11eを挟むようにして、耐圧容器11のフランジ部11eの下面に対してカシメる固定部57cとを有する。バルブ保持部57aの天面には、ステム52を通す中心孔が形成されている。なお、この形態ではカバーの内面が第2内容物A2と接触して腐食される恐れがあるため、カバーの内面にポリエチレンテレフタレートやナイロンなどの合成樹脂シートをラミネートしたり、ポリアミドイミドやエポキシフェノールなどの合成樹脂溶液を塗布して乾燥させた合成樹脂塗膜を設けることが好ましい。
このように構成されているため、図1の2液吐出製品10と同様に、第1内容物A1および第2内容物A2の両方が噴射剤Pと隣接しており、噴射剤Pから均等な圧力を受けることができる。また、第1内容物A1と第2内容物A2とは、第2空間S2(噴射剤P)を介さないと他方に移動できず耐久性が高い。また第1内容物A1および第2内容物A2の残量を小さくすることができる。
耐圧容器61の開口部が図1の耐圧容器11より径が小さい点、バルブアッセンブリ62のバルブホルダー63の円筒状の環状壁63aが内面でバルブ47のハウジング51を保持してバルブ保持壁として作用している点、耐圧容器61のフランジ部11eの外周に形成された環状凹部11gにO-リング64が設けられている点で図3の2液吐出製品40と異なる。他の構成は、2液吐出製品40と実質的に同じであり、同様の効果が得られる。なお、バルブホルダーの環状壁の幅やバルブ保持壁との間隔を調整することで、耐圧容器61および中容器42の首部の内径に応じて用いることができる。
図6の2液吐出製品65は、耐圧容器61と、中容器42と、パウチ13と、バルブアッセンブリ62と、パウチ内に充填される第1内容物A1と、耐圧容器61と中容器42との間の第1空間S1に充填される第2内容物A2と、中容器42とパウチとの間の第2空間S2に充填される噴射剤Pとを備えている。
図6の2液吐出製品65は、バルブホルダー63とバルブ47のハウジング51のシール構造が図5の2液吐出製品60と異なる。シール構造は、バルブ47のハウジング51の外周面に下方に向かって縮径する段部66が形成されており、その段部66が環状のガスケット67を介してバルブホルダー63の上面と係合している。他の構成は、2液吐出製品60と実質的に同じであり、同様の効果が得られる。
耐圧容器71は、口部71eの外周に雄ネジが形成されたものであり、他の構成は、図1の耐圧容器11と実質的に同じものである。
図8の2液吐出製品80は、耐圧容器71と、中容器42と、パウチ81と、耐圧容器71、中容器42およびパウチ81を閉じ、2つのバルブ機構を備えたバルブアッセンブリ82と、パウチ内に充填される第1内容物A1と、耐圧容器71と中容器42との間の第1空間S1に充填される第2内容物A2と、中容器42とパウチとの間の第2空間S2に充填される噴射剤Pとを備えている。2液吐出製品80は、第1内容物A1、第2内容物A2、噴射剤Pは、図1のものと実質的に同じであり、中容器42は、図3のものと実質的に同じであり、耐圧容器71は、図7の耐圧容器71と実質的に同じである。
連結部材83は、バルブアッセンブリ82と連結する筒状の上部83aと、袋体18を貼着するための扁平な筒状の下部83bと、中心軸を間隔をもって挟み、かつ、下部83bから下方に延びる2枚の平脚83cとを有する。袋体18は、上部が連結部材の下部83bに貼着している。これにより、2枚の開いた平脚83cがパウチ81内の第1内容物が少なくなったときにシート同士の密着を防止して第1内容物A1の通路を確保できる。
図9cに示すように、平脚83cの縦幅を、例えば連結部材の下部83bと同程度に厚くしてもよい。(少なくとも下部83bの中心孔より厚く)。この場合、第1内容物A1の通路を一層大きく確保できる。また、このように厚くした平脚83cと袋体18とを貼着してもよい。このように平脚83cと袋体18とを貼着することにより、パウチ18内の空間を、上下に延び、下端で連結した3本の並んだ空間に区画でき、中心の空間がバルブアッセンブリ82に連結したものとなる。つまり、中心の空間がディップチューブのような役割となる。そのため、確実にパウチ81内の第1内容物を最後までバルブアッセンブリ81に供給することができる。
栓本体91の中心には、栓体88を上下に貫通する筒状の第1ハウジング部93が形成されている。この第1ハウジング部93には、第1ハウジング部93内に上下動自在に挿入されるステム94と、そのステム94のステム孔を塞ぎ、第1ハウジング部93の上部開口を塞ぐステムラバー95と、ステム94を常時上方に付勢する第1バネ96とが設けられる。この第1ハウジング部93、ステム94、ステムラバー95、第1バネ96が第1バルブ機構86を構成する。つまり、第1バルブ機構86は、ステム94を押し下げる
ことにより開放される。第1ハウジング部93とパウチ81とは、第1ハウジング部93の下端の連結部93aと、パウチ81の連結部材83の上部83aとで連結されている。
フランジ部92には、側面外周から栓本体91の外周の位置まで半径方向に延びる筒状の側孔97が形成されており、その側孔97は、フランジ部92の下面から上方に延び、耐圧容器71の内溝17と連通する上下連通孔92aと連通している。側孔97には、図9dに示すように、上下(図面では左右)の先端が内側に折れ曲げられた筒状の第2ハウジング101と、その第2ハウジング101内に半径方向に移動自在に挿入される弁皿102と、その弁皿を半径方向外側に付勢する第2バネ103とが設けられている。この第2ハウジング101、弁皿102、第2バネ103が第2バルブ機構87を構成する。つまり、第2バルブ機構87は、弁皿102を押し込むことにより開放される。この第2バルブ機構87は、金属筒に弁皿102及び第2バネ103を挿入し、その金属筒の上下端を内側に折り曲げることにより第2ハウジング101を形成し、ユニット化したものである。また第2ハウジング101と第1空間S1とは、上下連通孔92a、内溝17を介して連通している。
吐出部材105は、図9eに示すように、側面に半径方向外側に突出する吐出筒106aを備えた筒状の本体106と、その本体に挿入される操作部107とからなる。本体106は、一方の開口部を蓋部材89の貫通筒89aに挿入し、他方の開口部に操作部107が挿入される。操作部107は、本体106内の内面とシールするように挿入されるピストン部107aと、そのピストン部107aから前方に突出した操作棒107bと、ピストン部107aから後方に本体106の外部に位置する指押部107cとからなる。つまり、使用者は、指押部107cを指で本体106方向に押すことにより、操作棒107bが第2バルブ機構87の弁皿102を押し、第2バルブ機構87を開放する。これにより空間S1内の第2内容物A2が空間S2内の噴射剤に押圧され、内溝17、上下連通孔92aを通り、第2ハウジング101内に至り、さらに、本体106から吐出筒106aの先端の吐出孔から吐出される。ここでは、第2バルブ機構87に用いられる吐出部材の一例を挙げるが、操作することによって第2バルブ機構87の弁皿を押すことができるものであれば、その構成は特に限定されない。また、ステム94と蓋部材89の貫通筒89aを同じ外径にし、本体106の開口部をステム94および貫通筒89aのいずれにも装着できるようにすることで、吐出部材をそれぞれ吐出したい内容物に応じてステム94あるいは貫通筒89aに装着できる。このように一つの吐出部材でそれぞれのバルブ機構を吐出操作できる。また、第2バルブ機構87としては、第1バルブ機構86のように、ステム、ステムラバーを用いたバルブ機構を用いても良い。
