【発明の属する技術分野】
本発明は、浴室の防黴方法、より詳しくは、黴の発生を予防することができる防黴成分を含有する薬剤を自噴により噴霧又は燻煙・燻蒸し、浴室内面の天井及び壁面に塗布することを特徴とする浴室の防黴方法や、かかる浴室の防黴方法に用いる浴室用防黴セットに関する。
【0002】
【従来の技術】
従来、浴室での黴発生の予防や発生した黴の除去に関して、有効塩素として3重量%以上の次亜塩素酸ソーダ、3重量%以上のケイ酸ナトリウムマグネシウム及び水を含有するかび取り剤(特開平11−217596号公報)や、イソプロピルアルコ−ル及び/またはエタノ−ルと、有機酸銀及び低級アルキル基で置換されていてもよいベンゾトリアゾ−ルとを含有する抗菌・抗黴性液剤(特開平10−338605号公報)や、ナットウ菌の懸濁液をカビ発生及び繁殖の生ずるおそれがあるか、あるいは生じている場所に散布する風呂場の防ばい方法(特開平8−301712号公報)や、過酸化水素あるいは水溶液中で過酸化水素を生成する過酸化物が生成過酸化水素換算で0.5〜60重量%、シアン酸のアルカリ金属塩又はシアン酸のアンモニウム塩が0.2〜30重量%からなる水溶液であって、そのpHが7〜13であることを特徴するカビ取り剤組成物(特開平8−245987号公報)や、過酸化物0.5〜60重量%、ジシアンジアミド0.2〜30重量%、アルカリ金属水酸化物又はアルカリ土類金属水酸化物0.1〜10重量%及び水40〜99重量%からなり、pHが8.0〜13.0である組成物(特開平8−73896号公報)や、マグネシウム、カルシウム、ストロンチウム、アルミニウム、マンガン、ニッケル、銅、及び、亜鉛からなる群の中から選ばれた2種以上の金属の難溶性オルトリン酸複塩に0.1〜5.0重量%の銀を担持させた粒径30μm以下の抗菌・抗カビ性リン酸複塩0.1〜20重量%、分散液4.9〜60重量%、および、噴射剤20〜95重量%からなる防菌・防カビ用噴霧剤(特開平7−309706号公報)や、浴室、各種収納庫などに設置しておくだけで、その空間内を3〜4ヵ月の長期にわたって防かび性とすることができる、亜塩素酸のアルカリ金属塩またはアルカリ土金属塩100重量部に対し、pHが7.5〜12.0の水の300〜5,000重量部、自重量の30重量%以上の吸水能をもった無機および/または有機物の粉末または顆粒の5〜5,000重量部および硫酸カルシウムの半水塩または一水塩の500〜10,000重量部を加えた混合物を主成分とし、これらをかきまぜて固化させた防かび性固形組成物(特開平7−17818号公報)や、イソチオシアン酸アリルと緑茶エキスに有機溶剤を配合してなる抗微生物用組成物(特開平5−201822号公報)などが知られている。
【0003】
浴室の壁面や天井面等にカビが付着した場合、換気をしながら、カビが付着している部分に市販のスプレー式のカビ取り剤を20〜30cm離れたところから噴霧し、所定の時間経過後に水洗いを行なうことが一般的に行われている。その他、特許第3014041号公報には、窓を閉め切り、浴槽から上昇している湯気に向けたり上に向けてスプレー容器から漂白剤を霧状に噴霧することにより、浴室内に霧状に噴霧された漂白剤の微粒子が、上昇気流となっている湯気と共に上昇し、これらの湯気の微粒子と漂白剤の微粒子とが混合しながら浴室内を拡散して壁面や天井面の全面、つまり浴室の内面全体にわたって付着することを用いて、天井面に付着しているカビをも完全に除去するカビ取用噴霧装置が記載されている。
【0004】
また従来、農薬、入浴剤、殺菌剤、殺虫剤、医薬品、入れ歯洗浄剤、肥料、植物成長調整剤などの有効成分が粉末、ペレット状、錠剤などの形態であるため、水に対して溶解したり、拡散するのに手間と時間がかかるという問題を改善するために、有効成分に炭酸塩や炭酸水素塩、及び水溶性固体酸を配合し、例えば顆粒剤又は錠剤とし、これを水中に入れると反応してガスが発生し、含有された有効成分が水に溶解するようにした発泡製剤が知られている。例えば、農業用の発泡製剤の例としては、除草成分、界面活性剤、発泡剤、結合剤などを含有する水田除草用錠剤又はカプセル(特開平3−223203号公報)、農薬活性成分、炭酸塩、水溶性固体酸及び高沸点溶剤からなる水面施用発泡性農薬製剤(特開平5−85901号公報)、農薬活性成分、炭酸塩もしくは炭酸水素塩、固体酸及び酸化ホウ素からなる安定化された発泡性農薬製剤(特開平6−211604号公報)などがあり、植物成長調整剤の発泡製剤の例としては、アルカリ土類金属の炭酸塩に、固体酸或は/及び分解して酸となる固体の塩、更にワックス類、脂肪酸等の疎水性材料を添加せしめたことを特徴とする二酸化炭素ガス発生剤(特開平6−327400号公報)などがあり、医薬用の発泡製剤の例としては、炭酸塩及び酸性物質を含有する発泡性錠剤において、メタリン酸ナトリウムを6重量%以上配合した発泡性錠剤(特開平7−277959号公報)などがある。
【0005】
また、エアゾールスプレー装置として、スプレー罐内に第1の部屋と第2の部屋とから成るガス発生器を収納し、第1の部屋とスプレー罐内は第1の部屋の略中央に伸びる管から成る第1通路により連通し、第1の部屋と第2の部屋は第1の部屋の略中央に伸びる管から成る第2通路より連通し、第1通路の管の端部と第2通路の管の端部とを断面がH型をした連結部材で覆い、スプレー罐内には噴射する薬剤を収納し、第2の部屋内の水溶液は第1の部屋内の物質と反応するとガスを発生するものであり、第1の部屋内の圧力が第2の部屋内の圧力より小さくなると第2通路を通って水溶液が第1の部屋内に流入してガスを発生し、スプレー罐内の圧力を常に略一定に保つようにしたことを特徴とするエアゾールスプレー装置(特開昭57−107259号公報)等が知られている。
【0006】
【発明が解決しようとする課題】
本発明の課題は、防黴成分を含有する薬剤を、自噴により噴霧又は燻煙・燻蒸し、作業者がその場にいなくとも浴室内面の天井及び壁面に塗布することにより、黴の発生を予防することができる安全かつ簡便な浴室の防黴方法や浴室用防黴セットを提供することにある。
【0007】
【課題を解決するための手段】
浴室の天井や壁面には多湿による黴が繁殖するため、次亜塩素酸ナトリウムの水溶液を主成分とする薬剤を吹きつけて黴を分解除去することが行われており、泡状薬剤として吹きつける黴除去剤や粘性薬剤として吹きつける黴除去剤等が実用に供されている。これらの黴除去剤は黴を取り除く上で有効であるが、次亜塩素酸ナトリウム等の塩素系酸化剤は刺激性の強い薬剤であり、毒性が強いため吹きつけ作業時には作業者は保護具を着用する必要があるが、一般家庭では完全な保護具を準備することが困難であるため、危険な状態で作業が行われているのが実態である。特に、天井の黴に薬剤を吹きつける場合は薬剤が作業者の全身にかかり、極めて危険な状態で作業を行わなければならないという問題があった。
【0008】
浴室の天井及び壁面に適用される防黴剤(黴発生予防剤)や黴除去剤の塗布は、これら薬剤のミストや粉塵を作業者が吸引するため危険かつ不快な作業であり、これら薬剤の浴室の天井及び壁面への塗布時に作業者が浴室外に退避できるようにするためには、作業者がその場にいなくとも防黴液剤や黴除去液剤等の液状物を噴霧することが必要である。しかし、殺虫剤を加熱し気散させ室内のゴキブリ等の害虫を殺虫する燻煙剤・燻蒸剤や、殺虫剤を圧縮ガスで液状薬剤として噴霧させるエアゾール遅延噴射式殺虫剤等が提案され、実用に供されているが、浴室の天井及び壁面に浴室用黴防止剤を塗布するために、これらの装置、手段を使用する方法は現在まで提案されていなかった。
【0009】
本発明者らは、作業者がその場にいなくとも防黴液剤や黴除去液剤等の液状物を噴霧することができる自噴式噴霧器について鋭意研究し、次亜塩素酸ナトリウム等の塩素系酸化剤と固体酸等の酸性物質とを共存させると塩素ガスが発生する可能性があることから、これらを共存させないタイプの自噴式噴霧器とすること、地球環境を考えて再使用が可能な自噴式噴霧器とすること、金属腐食性を有する次亜塩素酸ナトリウム等の塩素系酸化剤に耐性を有するプラスチック製の自噴式噴霧器とすることを基本的なコンセプトとして、液状物貯留室と、ガス発生室と、ガス発生室で発生したガスを液状物貯留室へ導入するための液状物貯留室とガス発生室との連通部とを有し、前記液状物貯留室には、液状物投入口及び該液状物投入口を密閉しうる密閉蓋と、液状物貯留室内の底部近傍から密閉蓋又は液状物貯留室上壁を気密に貫通し液状物貯留室外に延び、液状物貯留室内端部に液状物取入れ口、液状物貯留室外端部に噴霧ノズルをもつ液状物噴出管とが設けられ、前記ガス発生室には、ガス発生剤投入口及び該ガス発生剤投入口を密閉しうる密閉蓋が設けられ、ガス発生室で発生するガスのガス圧により液状物を噴霧ノズルから噴霧することができる再使用可能なプラスチック製の自噴式噴霧器を開発した。
【0010】
そして、かかる自噴式噴霧器には、水と接触することによりガスを発生し、発生するガスのガス圧により防黴液剤や黴除去液剤等の液状物を作業者がその場にいなくとも噴霧することができる、自噴式噴霧器用の固体無機過酸化物と固体酸化物、又は炭酸塩と固体酸を主成分とするガス発生剤が必要となることに着目した。固体無機過酸化物と固体酸化物、又は炭酸塩と固体酸とを粉末状態で水中に投入すると、初期には激しく反応するが、均一混合している部分の反応が終了すると、水中で固体無機過酸化物と固体酸化物、又は炭酸塩と固体酸が分離し、反応が進まなくなる現象、例えば、易溶性の固体酸と炭酸塩を混合すると固体酸の水溶液中に炭酸塩の結晶が沈んだ状態になり、中性反応液で結晶が覆われるため反応が停止する現象や、遅溶性の固体酸を添加すると固体酸又は炭酸塩の結晶の内、微細粒子の結晶に気泡が附着し液面に浮いてしまい、反応が遅くなる現象等が生起する場合があり、かかる分離を抑制するために、固体無機過酸化物と固体酸化物、又は炭酸塩と固体酸の粉末混合物を加圧成形した造粒品とすることが好ましいことや、特に、液状物貯留室とガス発生室との連通部に遮断具が設けられていないタイプの自噴式噴霧器の場合、遮断具が無くても初期段階から安定に噴霧可能とするには、造粒品と粉末品との混在物を使用すると、初期の急速なガス発生を粉末品で行い、造粒品は発生した気泡により分離した粉末混合品成分を攪拌し反応を促進するとともに、固体無機過酸化物と固体酸化物、又は炭酸塩と固体酸が分離しないためにガスを安定に発生させることができることなどを見い出した。本発明は以上の経緯により完成するに至ったものである。
【0011】
すなわち本発明は、
(1)液状物貯留室と、ガス発生室と、ガス発生室で発生したガスを液状物貯留室へ導入するための液状物貯留室とガス発生室との連通部とを有し、前記液状物貯留室には、液状物投入口及び該液状物投入口を密閉しうる密閉蓋と、液状物貯留室内の底部近傍から密閉蓋又は液状物貯留室上壁を気密に貫通し液状物貯留室外に延び、液状物貯留室内端部に液状物取入れ口、液状物貯留室外端部に噴霧ノズルをもつ液状物噴出管とが設けられ、前記ガス発生室には、水と接触することによりガスを発生するガス発生組成物からなるガス発生剤投入口及び該ガス発生剤投入口を密閉しうる密閉蓋が設けられ、ガス発生室で発生するガスのガス圧により液状物を噴霧ノズルから噴霧することができる再使用可能な自噴式噴霧器を用いて、防黴成分を含有する薬剤を、自噴により噴霧又は燻煙・燻蒸し、浴室内面の天井及び壁面に塗布することを特徴とする浴室の防黴方法、

また本発明は、
(6)防黴液剤と自噴式噴霧器と水と接触することによりガスを発生するガス発生組成物からなるガス発生剤とを備え、自噴式噴霧器が液状物貯留室と、ガス発生室と、ガス発生室で発生したガスを液状物貯留室へ導入するための液状物貯留室とガス発生室との連通部とを有し、前記液状物貯留室には、液状物投入口及び該液状物投入口を密閉しうる密閉蓋と、液状物貯留室内の底部近傍から密閉蓋又は液状物貯留室上壁を気密に貫通し液状物貯留室外に延び、液状物貯留室内端部に液状物取入れ口、液状物貯留室外端部に噴霧ノズルをもつ液状物噴出管とが設けられ、前記ガス発生室には、水と接触することによりガスを発生するガス発生組成物からなるガス発生剤投入口及び該ガス発生剤投入口を密閉しうる密閉蓋が設けられ、ガス発生室で発生するガスのガス圧により液状物を噴霧ノズルから噴霧することができる再使用可能な自噴式噴霧器であることを特徴とする浴室用防黴セットに関する。
【0015】
【発明の実施の形態】
本発明の浴室の防黴方法としては、防黴成分を含有する薬剤を自噴により噴霧又は燻煙・燻蒸し、浴室内面の天井及び壁面に塗布する方法であれば特に制限されるものではなく、ここで自噴とは、作業者がその場にいなくとも薬剤を噴霧又は燻煙・燻蒸することをいい、かかる噴霧又は燻煙・燻蒸に用いられる自噴式噴霧器や自噴式燻煙・燻蒸器としては公知のものを用いることができる。例えば、自噴式燻煙・燻蒸器としては、セラミックスヒーター等を用い、電圧変動、周囲の環境温度に表面温度が左右されにくく、常に安定した蒸散量を維持することができ、再使用可能なものが好ましく、かかる自噴式燻煙・燻蒸器を用いての燻煙・燻蒸に際しては公知の助剤を用いることもできる。また、自噴式噴霧器も、自噴式燻煙・燻蒸器同様に、再使用可能なものが好ましい。
【0016】
上記再使用可能な自噴式噴霧器としては、液状物貯留室と、ガス発生室と、ガス発生室で発生したガスを液状物貯留室へ導入するための液状物貯留室とガス発生室との連通部とを有し、前記液状物貯留室には、液状物投入口及び該液状物投入口を密閉しうる密閉蓋と、液状物貯留室内の底部近傍から密閉蓋又は液状物貯留室上壁を気密に貫通し液状物貯留室外に延び、液状物貯留室内端部に液状物取入れ口、液状物貯留室外端部に噴霧ノズルをもつ液状物噴出管とが設けられ、前記ガス発生室には、ガス発生剤投入口及び該ガス発生剤投入口を密閉しうる密閉蓋が設けられ、ガス発生室で発生するガスのガス圧により液状物を噴霧ノズルから噴霧することができる噴霧器が好ましく、液状物貯留室とガス発生室との連通部に遮断具が設けられていない構造が簡単で作製コストが安価な噴霧器や、液状物貯留室とガス発生室との連通部又はその近傍に遮断具、特に液状物貯留室とガス発生室とのガス圧が0.5kg/cm2以上になると、連通部の遮断が解除される遮断具が設けられている噴霧器や、ガス発生室にガスを放出することができるガス抜き弁を有する取扱い上安全な噴霧器や、液状物貯留室とガス発生室と連通部とが塩素系薬剤に対して耐性を有するプラスチック製の噴霧器がさらに好ましく、遮断具の有無にかかわらず、ガス抜き弁を有するプラスチック製の噴霧器が特に好ましい。以下、作業者がその場にいなくとも防黴液剤を噴霧することができる好ましい態様の自噴式噴霧器を図面に基づいて説明する。
【0017】
図1には、液状物貯留室10と、ガス発生室20と、ガス発生室で発生したガスを液状物貯留室へ導入するための液状物貯留室とガス発生室との連通部30とを有し、液状物貯留室10には、液状物投入口11及び該液状物投入口を密閉しうる密閉蓋12と、液状物貯留室内の底部近傍から密閉蓋を気密に貫通し液状物貯留室外に延び、液状物貯留室内端部に液状物取入れ口13a、液状物貯留室外端部に噴霧ノズル13bをもつ液状物噴出管13とが設けられ、前記ガス発生室20には、ガス発生剤投入口21及び該ガス発生剤投入口を密閉しうる密閉蓋22が設けられている自噴式噴霧器1が示されている。この再使用可能なタイプの自噴式噴霧器1はプラスチック製であり、上記連通部30は、遮断具を有さない、液状物貯留室10とガス発生室20との連絡通路として形成されている。ガス発生室20で発生したガスにより、液状物貯留室10内のガス圧が上昇すると、液状物表面が加圧される結果、液状物は液状物噴出管13の液状物取入れ口13aを経由して噴霧ノズル13bから噴霧されることになる。また、図示はしていないが、噴霧ノズルが閉塞した場合などにガスを放出するためのガス抜き弁を、液状物貯留室10やガス発生室20の上壁に設けておくこともできる。このタイプの自噴式噴霧器1の再使用に際しては、内部を水道水で洗浄すればよい。
【0018】
図2には、液状物貯留室10と、ガス発生室20と、ガス発生室で発生したガスを液状物貯留室へ導入するための液状物貯留室とガス発生室との連通部30とを有し、液状物貯留室10には、液状物投入口11及び該液状物投入口を密閉しうる密閉蓋12と、液状物貯留室内の底部近傍から液状物貯留室上壁を気密に貫通し液状物貯留室外に延び、液状物貯留室内端部に液状物取入れ口13a、液状物貯留室外端部に噴霧ノズル13bをもつ液状物噴出管13とが設けられ、前記ガス発生室20には、ガス発生剤投入口21及び該ガス発生剤投入口を密閉しうる密閉蓋22が設けられて、前記連通部30には、キャップ状の中空ゴム栓(遮断具)31が設けられている自噴式噴霧器2が示されている。この再使用可能なタイプの自噴式噴霧器2はプラスチック製であり、上記連通部30は、液状物貯留室10とガス発生室20との共通側壁に形成され、この連通部30に設けられたキャップ状の中空ゴム栓(遮断具)31は、例えば液状物貯留室10とガス発生室20とのガス圧差が0.5kg/cm2以上になると、ガス圧により連通部30から液状物貯留室10内へと脱落し、連通部の遮断が解除されるようになっており、液状物貯留室10内のガス圧が上昇すると、液状物表面が加圧される結果、液状物は液状物噴出管13の液状物取入れ口13aを経由して噴霧ノズル13bから噴霧されることになる。また、図示はしていないが、噴霧ノズルが閉塞した場合などにガスを放出するためのガス抜き弁を、ガス発生室20の上壁に設けておくこともできる。このタイプの自噴式噴霧器2の再使用に際しては、内部を水道水で洗浄した後、キャップ状の中空ゴム栓をピンセット等で連通部30に再セットすればよい。
【0019】
図3には、液状物貯留室10と、ガス発生室20と、ガス発生室で発生したガスを液状物貯留室へ導入するための液状物貯留室とガス発生室との連通部30とを有し、液状物貯留室10には、液状物投入口11及び該液状物投入口を密閉しうる密閉蓋12と、液状物貯留室内の底部近傍から液状物貯留室上壁を気密に貫通し液状物貯留室外に延び、液状物貯留室内端部に液状物取入れ口13a、液状物貯留室外端部に噴霧ノズル13bをもつ液状物噴出管13とが設けられ、前記ガス発生室20には、ガス発生剤投入口21及び該ガス発生剤投入口を密閉しうる密閉蓋22が設けられて、前記連通部30には、半円状の二枚のディスクが開閉する構造を有する二葉弁(バタフライ弁)32が設けられている自噴式噴霧器3が示されている。この再使用可能なタイプの自噴式噴霧器3はプラスチック製であり、上記連通部30は、液状物貯留室10とガス発生室20との共通側壁に形成され、この連通部30に設けられた二葉弁(バタフライ弁)32は、例えば液状物貯留室10とガス発生室20とのガス圧差が0.5kg/cm2以上になると、ガス圧により半円状の二枚のディスクが開き、連通部の遮断が解除されるようになっており、液状物貯留室10内のガス圧が上昇すると、液状物表面が加圧される結果、液状物は液状物噴出管13の液状物取入れ口13aを経由して噴霧ノズル13bから噴霧されることになる。また、図示はしていないが、噴霧ノズルが閉塞した場合などにガスを放出するためのガス抜き弁を、ガス発生室20の上壁に設けておくこともできる。このタイプの自噴式噴霧器3の再使用に際しては、内部を水道水で洗浄すればよい。

【0022】
上記無機固体過酸化物としては、固体状態で安定であり、水、必要に応じて酸性水と接触することにより過酸化水素を発生する性質を有する化合物であれば特に制限されるものではなく、酸性水と接触させる場合には、組成物として固体酸を含有させておき、水と接触させることもできる。無機固体過酸化物として具体的には、過炭酸カリウム、過炭酸ナトリウム等の過炭酸塩、過硫酸ナトリウム、過硫酸カリウム等の過硫酸塩、過硼酸カリウム、過硼酸ナトリウム等の過硼酸塩などを好適に例示することができ、これらは単独あるいは2種以上の混合物として用いることができる。また、他の態様の上記無機固体過酸化物として、炭酸塩過酸化水素化物、硼酸塩過酸化水素化物等の無機塩過酸化水素化物を好適に例示することができ、具体的には、K2CO3・2H22・0.5H2O、K2CO3・3H22、Na2CO3・H22・0.5H2O、Na2CO4・0.5H2O、Na2CO4・H22、Na2CO3・3H22、Na2BO2・H22・3H2O、NaB47・H22・9H2O、KBO3・0.5H2O等を挙げることができ、これらは単独あるいは2種以上の混合物として用いることができる。

[Problems to be solved by the invention]
The problem of the present invention is that spraying or smoke / fumigation of a chemical containing an antifungal component by self-injection and applying it to the ceiling and wall surface of the bathroom inner surface even when the operator is not on the spot, An object of the present invention is to provide a safe and simple bathroom protection method and bathroom protection set that can be prevented.
[0007]
[Means for Solving the Problems]
Since the cocoon grows on the ceiling and walls of the bathroom due to high humidity, it is sprayed as a foamy chemical by spraying a chemical mainly composed of an aqueous solution of sodium hypochlorite. A wrinkle remover or a wrinkle remover that is sprayed as a viscous drug is put into practical use. These soot removal agents are effective in removing soot, but chlorine-based oxidizers such as sodium hypochlorite are highly irritating agents and are highly toxic. Although it is necessary to wear it, it is difficult to prepare complete protective equipment in a general household, so the actual situation is that the work is performed in a dangerous state. In particular, when a medicine is sprayed on the ceiling wall, there is a problem that the medicine is applied to the whole body of the worker and the work must be performed in an extremely dangerous state.
[0008]
The application of antifungal agents (anti-fogging agents) and anti-fogging agents applied to the ceiling and walls of the bathroom is a dangerous and uncomfortable operation because the worker sucks the mist and dust of these agents. In order to enable the worker to retreat outside the bathroom when applying to the ceiling and wall surface of the bathroom, it is necessary for the worker to spray a liquid material such as an antifouling liquid or a wrinkle removing liquid even if the worker is not present It is. However, smoke and fumigants that heat insecticides and disperse them to kill insects such as indoor cockroaches, and aerosol delayed spray insecticides that spray sprayed pesticides as liquid chemicals with compressed gas, etc. However, a method of using these devices and means for applying a bathroom antifouling agent to the ceiling and wall of the bathroom has not been proposed so far.
[0009]
The present inventors have earnestly studied a self-injection sprayer capable of spraying liquid materials such as antifungal liquids and soot removal liquids, even when the worker is not present, and chlorinated oxidation such as sodium hypochlorite. Since chlorine gas may be generated when an agent and an acidic substance such as a solid acid coexist, a self-injection type sprayer that does not coexist with these, and a self-injection type that can be reused considering the global environment The basic concept is to make a sprayer and to make a plastic self-injection sprayer that is resistant to chlorinated oxidants such as sodium hypochlorite, which has metal corrosive properties. And a communicating portion between the liquid material storage chamber and the gas generation chamber for introducing the gas generated in the gas generation chamber into the liquid material storage chamber. Seal the liquid inlet The hermetic lid and the bottom of the liquid material storage chamber are hermetically penetrated through the hermetic lid or the upper wall of the liquid material storage chamber and extend outside the liquid material storage chamber. A liquid material jet pipe having a spray nozzle is provided in the section, and the gas generating chamber is provided with a gas generating agent inlet and a sealing lid capable of sealing the gas generating agent inlet, and is generated in the gas generating chamber. A reusable plastic self-injection sprayer that can spray liquids from the spray nozzle by the gas pressure of the gas has been developed.
[0010]
Such a self-injection sprayer generates gas by contact with water, and sprays a liquid material such as an antifungal solution or a soot removal liquid agent even if the operator is not on the spot by the gas pressure of the generated gas. It has been noted that a gas generating agent based on solid inorganic peroxides and solid oxides or carbonates and solid acids for self-injecting sprayers is required. When solid inorganic peroxide and solid oxide, or carbonate and solid acid are put into water in powder state, they react vigorously at the beginning, but when the reaction of the uniformly mixed part is completed, solid inorganic in water Peroxide and solid oxide, or carbonate and solid acid are separated and the reaction does not proceed, for example, when a readily soluble solid acid and carbonate are mixed, carbonate crystals precipitate in the aqueous solution of solid acid The reaction is stopped because the crystal is covered with a neutral reaction solution, and when a slow-dissolving solid acid is added, bubbles are attached to the fine particles of the solid acid or carbonate crystals, resulting in a liquid surface. In order to suppress such separation, a powder mixture of solid inorganic peroxide and solid oxide or carbonate and solid acid was pressure-molded. It is preferable to use a granulated product. In the case of a self-injection type sprayer in which no barrier is provided at the communication part between the material storage chamber and the gas generation chamber, in order to enable stable spraying from the initial stage without a barrier, granulated products and powder When the mixture with the product is used, the initial rapid gas generation is performed with the powder product, and the granulated product promotes the reaction by stirring the components of the powder mixture separated by the generated bubbles, and the solid inorganic peroxide and It has been found that gas can be generated stably because solid oxide or carbonate and solid acid are not separated. The present invention has been completed by the above process.

By making such a multilayer structure, the disintegration of the outer layer portion of the tablet or the like is promoted, the release of the solid inorganic peroxide, solid oxide, carbonate compound or solid acidic substance is accelerated, and contact with water This makes it possible to easily control the amount and timing of gas generation. Such a multilayer structure can be used particularly advantageously for increasing the initial pressure in a self-injection sprayer of the type in which a blocking member is not provided at the communication portion between the liquid material storage chamber and the gas generation chamber. Further, a multilayered structure composed of the pressure-molded body (I) and the pressure-molded body (II) or the like containing a solid inorganic peroxide and solid oxide, or a carbonate compound and a solid acidic substance.

The trouble of separately packaging the gas generating composition containing the salt compound and the solid acidic substance can be omitted. For example, when a gas generating agent composed of a gas generating composition packaged with a water-soluble film or a water-dispersible film is introduced into a gas generating chamber and water is added to start a gas generating reaction, the gas generating agent is packaged with a water-soluble film or the like. Therefore, it is possible to delay the gas generation time slightly, and it is possible to earn time for the worker to escape from the bathroom after the operation of the apparatus. Examples of the water-soluble film include partially saponified polyvinyl alcohol, modified polyvinyl alcohol, polyethylene oxide, and methylcellulose film. Examples of the water-dispersible film include a mixture film of fibers and a water-soluble polymer. Can be illustrated. In addition, when a gas generating agent composed of a gas generating composition packaged with a slow water film that gradually passes water such as nonwoven fabric or Japanese paper is introduced into the gas generating chamber and water is added to start the gas generating reaction, Gas is generated by contact of the water that has passed through and the gas generating composition, and by rupturing the bag, the drug can contact a large amount of water at a time, and a large amount of gas can be generated at a time.
