本発明は、再使用可能な自噴式噴霧器、より詳しくは、水と接触することによりガスを発生するガス発生剤を用い、発生するガスのガス圧により黴発生予防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に関する。

【従来の技術】
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。
【０００３】
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。
【０００４】
また従来、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。

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の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。
【０００６】
【発明が解決しようとする課題】
本発明の課題は、水と接触することによりガスを発生するガス発生剤を用い、発生するガスのガス圧により黴発生予防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再使用可能な自噴式噴霧器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黴発生予防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薫煙剤・薫蒸剤や、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、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を含む浴室用黴除去剤の塗布にこれらの装置、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黴発生予防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黴発生予防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。

【００２３】
上記炭酸塩化合物としては、炭酸塩、重炭酸塩、過炭酸塩から選ばれる化合物であれば特に限定されるものではなく、具体的には、例えば炭酸ナトリウム、炭酸水素ナトリウム（重炭酸ナトリウム）、過炭酸ナトリウム、セスキ炭酸ナトリウム、炭酸カリウム、炭酸水素カリウム、過炭酸カリウム、セスキ炭酸カリウム、炭酸アンモニウム、炭酸水素アンモニウム、セスキ炭酸アンモニウム、炭酸カルシウム、炭酸マグネシウム、炭酸リチウム、炭酸水素リチウム等を挙げることができ、特に炭酸水素ナトリウム、炭酸ナトリウムが好ましく用いられる。これらは単独で用いてもよく、２種以上を任意の割合で組み合わせて用いてもよい。

[0006]
[Problems to be solved by the invention]
An object of the present invention is to use a gas generating agent that generates gas when it comes into contact with water, and the operator can avoid liquids such as a soot prevention liquid agent and a soot removing liquid agent by the gas pressure of the generated gas. Another object of the present invention is to provide a reusable self-injecting sprayer that can be sprayed together.
[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 the anti-fogging agent and the anti-fogging agent 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 drugs. In order to enable the worker to evacuate outside the bathroom when applying to the skin, it is necessary for the worker to spray a liquid material such as a wrinkle-preventing liquid or a wrinkle-removing liquid even if the worker is not on the spot. However, fumigants and fumigants that heat insecticides and disperse them to kill insects such as cockroaches in the room, aerosol delayed spray type insecticides that spray sprayed insecticides as liquid chemicals with compressed gas, etc. Although being put into practical use, no method has been proposed to date to use these devices and means for the application of bathroom soot removers containing chlorinated oxidants such as sodium hypochlorite, which has metal corrosive properties. It was.
[0009]
The present inventors have earnestly researched a self-injection type sprayer that can spray liquid substances such as a wrinkle generation preventing liquid and a wrinkle removal liquid even if the worker is not on the spot, and a chlorine system such as sodium hypochlorite. Since coexistence of an oxidizing agent and an acidic substance such as a solid acid may generate chlorine gas, a self-injection sprayer that does not coexist with these, and a self-injection that can be reused in consideration of the global environment. The basic concept is to use a plastic spray sprayer that is resistant to chlorine-based oxidants such as sodium hypochlorite, which has metal corrosivity, and a liquid material storage chamber and gas generation And a communication part 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, the liquid material storage chamber includes a liquid material inlet and Close the liquid material inlet Airtight lid and the bottom of the liquid material storage chamber from the bottom of the liquid material storage chamber and airtightly penetrates the top wall of the liquid material storage chamber and extends to the outside of the liquid material storage chamber. A liquid material ejection pipe having a spray nozzle at an outdoor end, and a gas generating agent inlet and a sealing lid capable of sealing the gas generating agent inlet are provided in the gas generating chamber; We have developed a reusable plastic self-injection sprayer that can spray liquids from the spray nozzle by the gas pressure of the generated gas.
[0010]
Such a self-injection sprayer generates gas when it comes into contact with water, and sprays liquids such as a soot-preventing liquid and a soot-removing liquid by the gas pressure of the generated gas even if the operator is not on the spot. 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.
[0011]
That is, the present invention has a liquid material storage chamber, a gas generation chamber, and a communication 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, The liquid material storage chamber includes a liquid material inlet, a sealing lid that can seal the liquid material inlet, and a liquid material that airtightly penetrates the sealing lid or the upper wall of the liquid material storage chamber from near the bottom of the liquid material storage chamber.

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.
