【発明の詳細な説明】 ガス発生装置 本発明はガス発生装置に関するものである。本発明の他の特徴はエアロゾル容 器の中に密封されたガス発生装置を有しこのガス発生装置がガスを発生してエア ロゾル容器の内圧を保持または増大させるエアロゾル容器に関するものである。 缶ビール工業において１つの型のガス放出装置が開発されている。１９９１年 ５月３０日公表のＷＯ９１／０７３２６は圧下ガスを収容する中空区画室を開示 している。この区画室が内部にビール缶を取付けられているので、缶が開かれた 時、中空区画室がその内容物をガスジェットとしてビールの中に放出する。 種々の理由にも関わらず、エアロゾル容器の中に配置されたガス発生装置は有 用であろう。エアロゾル工業においては、公知のようにＨＦＣ推進剤を環境上の 側面から排除する必要がある。代用品の選択はほとんどプロパン、ブタン、ペン タン、ヘキサンなどの低分子量炭化水素であった。しかしこれらは可燃性ガスで あって、発火源となりうる限られた器具の中に使用するには必ずしも適当でない 。これらの理由から缶ビール工業はさらに環境に優しい薬剤に移行しようとして いる。 前記のような有機性推進剤の代わりに非液化性推進ガスを使用する事は別の問 題を生じる。一般的液化性有機推進ガスと異なり、二酸化炭素および亜酸化窒素 はエアロゾル容器の中で得られる圧力（すなわち代表的には最大限１０乃至１２ バール）においては液化される事ができない。生成組成物が徐々にエアロゾル容 器から排出されるに従って、ヘッドスペース中の二酸化炭素および亜酸化窒素は 液化性推進剤の場合のように再充填できないので、ヘッドスペース中の圧力が降 下する。ヘッドスペース中の圧力が余り遅く降下するならば、エアロゾル容器か らの生成物の分与がもはや不可能となる。エアロゾル缶中の圧力の実際上および 法規上の制限は、缶の中に装入されうるガス量の上限を課している。この上限よ り高いガス量は過度の内圧を生じ安全上の危険要素を伴なう。 エアロゾル容器中のガス発生装置はこれらの問題点を解決するでろう。 これらの問題点およびその他の問題点を解決する１つの方法は、１９８２年２ 月３日に公表されたＥＰ−Ａ−０，０４４，８８７に開示されている。この公表 は酸成分およびアルカリ成分と共に組立てられた可撓性バッグを開示している。 これらの酸成分とアルカリ成分が相互に接触させられて反応してガスを放出し、 このガスがバッグを膨張させる。しかし可撓性バッグは自動包装ライン上でのそ の組立てとそのエアロゾル缶中の配置が困難でコスト高である。 本発明の１つの目的は容易に安価に製造する事のできるガス発生装置を提供す るにある。 本発明の他の目的は包装ライン上で、高速包装ライン上でもラインの最小限の 変更をもってエアロゾル容器の中に装入する事のできるガス発生装置を提供する にある。 本発明のさらに他の目的は、許容可能の内圧に関する缶仕様を超えないガス圧 を発生する事のできるエアロゾル缶中のガス発生装置を提供するにある。さらに 詳しくは、ガス発生装置が５０℃において１２バール以上の圧力を発生しない事 が好ましい。 本発明のガス発生装置は、少なくとも２区画室を有し、第１区画室と第２区画 室が密封可能の連通手段によって相互に接続され、前記第１区画室が液体を収容 し、この際に、前記密封連通手段が開かれた時に、第１区画室から液体の少なく とも一部が第２区画室の中に流入して、この液体が少なくとも一種の化学試薬と 接触して化学反応を生じガスを発生させるように成される。 発明の概要 本発明の目的は、実質的に剛性であり、またその壁体が少なくとも１つの孔を 有するので、発生ガスが放出されるように成されたガス発生装置によって達成さ れる。 本発明の第１実施態様において、第１区画室が酸性溶液を収容し、また第２区 画室が炭酸塩または重炭酸塩を収容する。本発明の第２実施態様において、第１ 区画室は水を収容し、第２区画室は固相の少なくとも２種類の化学試薬を収容し 、前記２種類の化学試薬は（ａ）酸と（ｂ）炭酸塩または重炭酸塩である。 図面の簡単な説明 付図は本発明のガス発生装置の１つの実施態様の横断面図である。 発明の詳細な説明 ガス発生装置によって発生されるガスは第２区画室または第１および第２区画 室のために選択された化学試薬に依存する。好ましくはアルカリ成分は炭酸塩ま たは重炭酸塩であるので、得られるガスは二酸化炭素である。本明細書において 、用語「炭酸塩」は炭酸塩または重炭酸塩を示すために使用される。炭酸塩は任 意の塩の形で使用する事ができるが、ナトリウム塩、カルシウム塩またはマグネ シウム塩が好ましい。酸は任意適当な酸とする事ができるが、クエン酸、リンゴ 酸、マロン酸、フマル酸、グリコール酸、酒石酸、アスパラギン酸、コハク酸、 グルタル酸、アジピン酸、アコニット酸、アスコルビン酸、塩化水素酸、硫酸ま たはその混合物から成るグループから選定される事が好ましい。特に好ましいの は有機酸、最も好ましくはマレイン酸である。 本発明の第１実施態様において、第１区画室は酸溶液を収容し、また第２区画 室は固体炭酸塩または重炭酸塩を収容する。本発明の第２実施態様においては、 第１区画室が水を収容し、第２区画室が固体状の少なくとも２種類の化学試剤の 混合物を収容し、これらの二種の化学試剤は（ａ）酸および（ｂ）炭酸塩または 重炭酸塩とする。 炭酸塩の固体形状および使用時に酸の固体形状は、例えば粉末またはタブレッ トとする事ができる。本発明の第２実施態様において、炭酸塩と酸は第２区画室 の中にバラバラの好ましくは予混合された粉末として配置する事ができる。さも なければ炭酸塩と酸のいずれかまたは両方がバラバラのタブレット状を成し、ま たは炭酸塩／酸性タブレット混合物の形とする事ができる。 液体が第１区画室から連通手段を通して第２区画室の中に移動する時に化学反 応が生じる。この連通手段はガスの最初の発生前に閉鎖され、次に一回または数 回開かれる。そのため、連通手段は好ましくは弁または破断膜を備える。本発明 の１つの実施態様によれば、弁は一回だけ開かれ、その後、発生ガスの実質的全 量の排出が生じるように設計される。本発明の他の好ましい実施態様において、 弁は、外圧が所定最低値以下に落ちた時に弁を開放し、また外圧が所定最高値を 超えた時に弁を閉鎖する手段を備える。本発明のこの実施態様においては、ガス 放出は化学的試剤の全量が消耗されるまで多数回繰り返される。 好ましくは第１区画室の壁体の少なくとも一部がガス透過性材料で形成される 。好ましくは第２区画室の壁体の少なくとも一部もガス透過性材料で形成される 。好ましくはこれらの壁体が少なくとも二酸化炭素に対して透過性とする。 付図について述べれば、第１区画室１と第２区画室２とを含むガス分与装置が 図示されている。これらの区画室は連通手段３によって相互に接続され、この連 通手段３は密封弁４によって密封される。この弁は弁軸５に連結される。第２区 画室２はその壁体の孔６を通してガス発生装置の外部と直接に連通する。これら の孔は閉鎖手段７によって閉鎖された状態に図示され、この閉鎖手段は装置外部 の物質が第２区画室の中に入って試薬を汚染する事を防止する。しかしこの閉鎖 手段７は第２区画室２の中で発生したガスの圧力によって開かれ、ガスをこの第 ２区画室の外部に通過させる。 本発明の好ましい実施態様において、第１区画室１は水を収容し、これに対し て第２区画室２は炭酸ナトリウムおよびマレイン酸の乾燥粉末から製造されたタ ブレット２０を収容する。しかし前述のように、溶液、粉末および各種の酸と塩 の種々の組合わせが可能である。 第１および第２区画室の壁体は透過性であって、装置全体を例えば１０バール の初期圧において平衡させる。外圧が所定レベル以下に下降した時、可撓性壁体 ２１が外側に膨張して、第２区画室中の圧力を低下させる。可撓性壁体２１は弁 軸５を介して弁４に連結されている。可撓性壁体２１の膨張と、第１区画室中の 圧力が第２区画室中の圧力を超えている事とによって、弁４が移動させられて、 第１区画室１と第２区画室２の間の連通手段３を移動させて開放する。これによ り、水が第１区画室１から第２区画室２の中に入らされて、炭酸塩と酸との化学 反応を発生させ二酸化炭素を放出する。二酸化炭素が閉鎖手段７を強制的に開き 、第２区画室の壁体の孔６を通してガス発生装置の外部に出る。 本発明の他のアスペクトにおいて、ガス発生装置が分与手段を備えた密封容器 、特にエアロゾル容器の中に配置される。好ましくはこのエアロゾル容器は、そ の内部を加圧するための推進ガスの初期装入物を備えている。特に適当な推進剤 は二酸化炭素、窒素、亜酸化窒素、酸素、空気およびその混合物を含む。過フッ 化炭化水素（例えば、ＣＦＣ，ＨＣＦＣおよびＨＦＣ）、アルカン（例えば、プ ロパン、ブタン、ペンタン、ヘキサン）などの液化性ガスを使用する事もできる が、環境上および引火性の配慮から好ましくは少量使用される。エアロゾル容器 の逐次使用後に内圧が落ちる。一定の最低圧において、ガス発生装置が前述のよ うに作動して追加的ガスをエアロゾル容器の中に放出し、その内圧を高める。 代表的には、密封容器は液状生成物を収容し、この液状生成物は弁または弁ノ ズル組立体などの分与手段によって分与される。 本発明の好ましい実施態様において、液状生成物は、分与手段が活性化された 時に泡の形で分与される。ガス発生装置を使用する事は泡の密度を容器の寿命中 ほぼ一定に保持できる事を意味する。それぞれ同等の重量の２０用量を分与した 時に最終用量の密度が第１用量の密度より１０％以上高くないように泡を分与す る事ができる。泡密度を測定するため、内部高さ６２ｍｍ、内径１１１ｍｍのガ ラスビーカを標準型石鹸溶液で脱脂し、蒸留水でよく洗浄する。次にビーカに泡 があふれるまで泡を充填し、次にビーカの上縁部をまっすぐな縁で払拭して余分 の泡を掻き落とす。充填されたビーカの重量（Ｗ２）と空ビーカの重量（Ｗ１） との差が泡の重量である。ビーカの容量（Ｖ）が既知である。従って泡密度は（ Ｗ２−Ｗ１）／Ｖで計算される。DETAILED DESCRIPTION OF THE INVENTION Gas generator The present invention relates to a gas generator.
