【発明の属する技術分野】
本発明は、水洗トイレの手洗い付きロータンクの手洗い部に載置し、手洗い部の上方のカランから給水される水に薬剤(芳香剤、洗浄剤、殺菌剤等)を混合するのに適した薬液供給具に関する。
【0002】
【従来の技術】
水洗トイレの手洗い付きロータンクの手洗い部に載置し、手洗い部の上方のカランから供給される水に薬剤(芳香剤、洗浄剤、殺菌剤等)を混合するために用いる薬液供給具として、特許文献1に記載されている水洗トイレ用薬剤供給具が知られている。この薬剤供給具は、液状の薬剤を収容する薬液タンク(薬剤容器)の底部に薬剤の導出孔を設け、その導出孔から薬剤を含浸体に導出して含浸させると共に、その含浸体が、カランから手洗い部に供給された水の流れに晒されるようにし、含浸体に含まれていた薬剤が水に溶解し、ロータンク内に流下するようにしたものである。
【0003】
【特許文献1】特開2001−342666号
【0004】
【発明が解決しようとする課題】
上述の薬液供給具は構造的に複雑であり、製造コストが高くつく。これに対し、より単純な機構の薬液供給具100xとしては、図5に示すように、液状の薬剤Aを収容する薬液タンク1と薬液タンク1の底部開口部2に取り付けたキャップ3からなり、キャップ3に薬液供給ノズル4と足6を設けたものが考えられる。薬液供給ノズル4の先端開口部5には、薬剤Aが、表面張力と薬液タンク1内が弱い負圧状態になることにより保持される。
【0005】
この薬液供給具100xを、ロータンクの手洗い部20の吸水口21上に載置し、水洗トイレの水をフラッシュさせることによりカランから手洗い部20に矢印のように水Wが供給されると、その水Wは薬剤Aを保持した薬液供給ノズル4を洗うようにしてロータンク内に流下する。したがって、この薬液供給具100xによれば、単純な機構で、カランからの給水の度に薬剤Aをロータンク内に混入することが可能となる。
【0006】
薬液タンク1内は、ロータンク内へ供給された薬剤Aの量に応じて負圧になるが、薬液供給ノズル4の先端開口部5に付着していた薬剤の希釈液、水又は空気がその先端開口部5から直ちに薬液タンク1内に入るので、薬液タンク1内は弱い負圧状態に戻る。以降、カランから給水される度にこの作用が繰り返され、薬剤Aがロータンク内に混入し、薬液タンク1内には、薬剤の希釈液、水又は空気が置換していく。
【0007】
しかしながら、この薬液供給具100xによれば、上述のように薬液タンク1内に水が置換していくために、薬液供給具100xの使用を重ねていくと、薬液タンク1内の薬剤Aが次第に希釈され、十分な薬効を持たない希釈液が残る場合がある。このような希釈液が薬液タンク1内に残ると、見かけ上薬液タンク1内に液剤があるために、十分な薬効がないにもかかわらず薬液供給具100xを使用し続けてしまうと言う問題が生じる。また、ロータンクに混入させる薬剤を青、緑等に着色し、便器の水封部に着色水が溜まるようにすることが一般になされているが、この場合の水封部の水は、薬剤の濃度が5%程度まで希釈されても着色されて見えるため、水封部の水の色によっても、薬液タンクA内の残液が十分な薬効を有するものであるか否かを判断することはできない。
【0008】
これに対し、本発明は、水洗トイレの手洗い付きロータンクの手洗い部に載置することによりロータンク内に薬剤を供給する薬液供給具において、薬液供給具の使用を重ねた場合に、十分な薬効のない希釈液が薬液タンク内に残らないようにすることを目的とする。
【0009】
【課題を解決するための手段】
本発明者は、薬液供給具の使用を重ねた場合に、薬液タンク内に十分な薬効のない希釈液が残るか否かは、薬液供給具の使用開始時における、水洗トイレの水のフラッシュ1回あたりの薬剤量の減少量を大きくすることが重要であり、そのためには、薬液供給具の使用開始時における薬液タンク内のヘッドスペースを大きくすることが有効であることを見出した。
【0010】
即ち、本発明は、液状の薬剤を収容する薬液タンク及び薬液タンクの底部開口部に取り付けられたキャップからなり、キャップの開口部から水洗トイレの手洗い付きロータンクに薬剤を供給する薬液供給具であって、該薬液供給具が薬液タンクのヘッドスペース増大機構を有する薬液供給具を提供する。
【0011】
ここで、ヘッドスペースとは、薬液タンク内の上部に存在する空間のことをいう。
【0012】
【発明の実施の形態】
以下、図面を参照しつつ、本発明を詳細に説明する。なお、各図中、同一符号は同一または同等の構成要素を表している。
【0013】
図1は、本発明の一態様の薬液供給具100Aの斜視図(a)と、その使用状態の断面図(b)であり、図2は、この薬液供給具100Aの組立方法を説明する断面図である。
【0014】
この薬液供給具100Aは、トイレ用芳香剤、洗浄剤、殺菌剤等の液状の薬剤Aを収容する薬液タンク1と、薬液タンク1の底部開口部2に取り付けられるキャップ3と、薬液タンク1の頂部7に着脱自在に設けられる天板10からなる。
【0015】
薬液タンク1は、薬剤補充の便宜上、図2(a)に示すように、薬剤Aを満たし、底部開口部2をシール部材8で密封した形態で提供することができる。
【0016】
キャップ3には薬液供給ノズル4と足6が該キャップ3に一体的に設けられ、その内部にはヘッドスペース増大機構として、薬剤収容部11が形成されている。薬液供給ノズル4の先端には先端開口部5が形成されており、ここに薬剤Aが表面張力と薬液タンク内が弱い負圧になることにより保持される。
【0017】
なお、この薬液供給具100Aは極めて構成が簡易であり、薬液タンク1やキャップ3や天板10は、それぞれプラスチック成型により容易に製造することができる。したがって、この薬液供給具100Aはローコストに得ることができる。
【0018】
薬剤Aとしては、粘度5〜1000mPa・s(20℃)に調整したものを使用し、薬液供給ノズル4の先端開口部5の孔径は1〜5mmとすることが好ましい。薬剤Aの粘度が1000mPa・sを超えるか、又は先端開口部5の孔径が1mmよりも狭いと、薬液タンク1から薬液供給ノズル4の先端にまで薬剤Aが導出されにくくなる。反対に薬剤Aの粘度が5mPa・sよりも低いか、又は先端開口部5の孔径が5mmよりも広いと、先端開口部5から薬剤Aが過度に漏出し易くなる。
【0019】
薬液供給具100Aの組立方法としては、まず、図2(a)、(b)に示すように、薬液タンク1の底部開口部2からシール部材8を剥がし、そこにキャップ3を嵌め、また、薬剤タンク1の頂部7に天板10を嵌める。次に、図2(c)に示すように、薬液タンク1の上下を逆さにする。これにより薬液タンク1内の薬剤Aがキャップ3内の薬剤収容部11に流入し、薬液タンク1にはヘッドスペースHSが形成され、薬液供給具100Aの使用形態となる。
【0020】
薬液供給具100Aの使用方法としては、図2(c)のように組み立てた薬液供給具100Aを水洗トイレの手洗い付きロータンクの手洗い部20のカランの下に載置し、薬液供給ノズル4を吸水口21に挿入する(図1(b))。
【0021】
薬剤吐出容器100Aを手洗い部20に載置後、水洗トイレの水がフラッシュされ、カランから水が供給されると、図1(b)のように、水Wは、まず、天板10に沿って放射状に流れ、次いで薬液タンク1の側面に沿って手洗い部20に流れ、吸水口21内に流れ込み、さらに薬液供給ノズル4に沿って流下し、その先端開口部5を洗うように流れ、ロータンク内に入る。したがって、先端開口部5に保持されていた薬剤Aが水Wでさらわれ、ロータンク内に混入することとなる。
【0022】
カランからの給水が止まると薬液供給ノズル4の先端開口部5に保持されている薬剤Aをさらう水の流れがなくなり、ロータンク内への薬剤Aの供給も止まる。薬液タンク1内は、ロータンク内に供給された薬剤Aの量に応じて負圧になるが、先端開口部5に付着していた薬剤の希釈液、水又は空気が直ちに先端開口部5から薬液タンク1内に入るので、薬液タンク1内は弱い負圧状態に戻り、カランからの給水前と同様に薬液供給ノズル4の先端開口部5には薬剤Aが保持される。
【0023】
以降、カランから給水される度にこの作用が繰り返される。
【0024】
ここで、水Wの水温がトイレの室温よりも低い場合には、カランからの給水により薬液タンク1内のヘッドスペースHSの空気が冷やされ、カランからの給水が止まると徐々に室温に戻る。したがって、この間にヘッドスペースHSの空気が膨張し、これによっても薬剤Aが吐出されるので、薬液タンク1内に水Wが混入することなく、確実に薬液タンク1内の液量が減ることになる。
【0025】
反対に水Wの水温がトイレの室温よりも高い場合には、カランからの給水時に薬液タンク1内のヘッドスペースHSが温められ、ヘッドスペースHSの空気が膨張し、これにより薬剤Aが吐出される。この薬剤Aの吐出時において、薬液タンク1内は温められて加圧状態であるため、薬液タンク1内に入る水Wの量は少ない。したがって、この場合にも薬液タンク1内の液量は減ることになる。
【0026】
このように、この薬液供給具100Aにおいては、キャップ3に薬剤収容部11が形成されていることにより使用開始時の薬液タンク1内にヘッドスペースHSが形成されるので、薬剤収容部11を設けず、使用開始時にヘッドスペースが形成されない場合に比して、上述の水温と室温の差異により、水Wが薬液タンク1内に混入しない状態で薬液タンク1から吐出される薬剤量を増大させることができる。したがって、この薬液供給具100Aによれば、使用を重ねることにより薬液タンク1内の残液が僅かとなる最後の方でも、その残液は十分な薬効を有する薬剤Aであり、薬効のない希釈液が薬液タンク1内に残ることが防止される。
【0027】
これに対して、使用開始時に薬液タンク1内にヘッドスペースがないと、専らカランからの給水時のみに薬液タンク1内の薬剤Aと水との置換がおき、薬剤Aが希釈されていくため、薬液タンク1内の液量が減りにくく、使用を重ねてもヘッドスペースが増大しない。また、薬液タンク1内に水が混入することにより、薬液タンク内の液性が変化して表面張力が上がり、いっそうヘッドスペースの空気の膨張による薬剤Aの吐出が行われにくくなる。このため、使用を重ねると、薬液タンク1内に薬効のない希釈液が残ることとなる。
【0028】
使用開始時のヘッドスペースHSの大きさは、大きすぎると薬剤Aの充填効率が悪く、小さすぎると、残液として希釈液が残らないようにする効果を得られなくなるので、薬液タンク1Aの容積の11〜50%とすることが好ましい。したがって、薬剤収容部11の容積は、このようなHSが形成されるように定めることが好ましい。
【0029】
なお、この薬液供給具100Aにおいて、天板10は、カランの水が薬液タンク1に直接的に当たることを防止し、それにより、薬液タンク1からの薬剤Aの供給量を、水温あるいは気温の変動によらず、安定化させる。薬液供給具100Aの使用開始時においては、上述のように、積極的に水温と気温の差異を利用し、ヘッドスペースHSの空気の膨張により薬液タンク1から薬剤Aが吐出されるようにすることが好ましいが、一旦、ヘッドスペースが薬液タンクの容積の50%程度以上となった以降は、水温と気温の差異を利用して薬液タンク1からの薬剤Aの供給量を増大させなくても、薬液タンク1内に薬効のない希釈液が残ることを防止できる。したがって、薬液タンク1からの薬剤Aの供給量を安定化させるため、天板10を設けることが好ましい。また、カランから供給された水は天板10にそって放射状に流れ、美しい水のベールの外観を呈するので、薬液供給具の使用感を向上させる点からも天板10を設けることが好ましい。
【0030】
本発明において、薬液供給具の使用開始時のヘッドスペースを増大させる機構は、キャップに限らず、薬液タンクに設けてもよい。
【0031】
例えば、図3は、薬液タンク1の側壁に、ヘッドスペース増大機構として蛇腹部12を設けた薬液供給具100Bの斜視図(a)及び断面図(b)である。
【0032】
この薬液タンク1は、薬剤補充の便宜上、図4(a)に示すように、蛇腹部12が縮められた状態で薬剤Aを満たし、底部開口部2をシール部材8で密封した形態で提供される。
【0033】
薬液供給具100Bの組立方法としては、まず、図4(a)、(b)に示すように、薬液タンク1の底部開口部2からシール部材8を剥がし、そこにキャップ3を嵌め、蛇腹部12を伸ばす。また、薬剤タンク1の頂部7に天板10を嵌める。次に、図4(c)に示すように、薬液タンク1の上下を逆さにする。薬液タンク1の蛇腹部12は伸ばされているので、薬液タンク1の上下を逆さにすることにより薬液タンク1内にはヘッドスペースHSが形成され、薬液供給具100Bの使用形態となる。なお、蛇腹部12を伸ばした状態に固定する方法としては、例えば、蛇腹部の伸ばした形状が元の縮んだ形状に復元しないように、蛇腹部の強度を強くするか、又は蛇腹部に平らな部分を設ける。
【0034】
こうして組み立てられた薬液供給具100Bは、前述の薬液供給具100Aと同様に使用される。そしてこの薬液供給具100Bによっても、使用を重ねた場合に、薬液タンク1内に薬効のない希釈液が残ることを防止できる。
【0035】
上述した薬液供給具100A、100Bは、ロータンク20の吸水口21上にカランが位置する手洗い部に載置することができるが、本発明においては、薬液供給ノズル4を足6に対して短く形成することにより、ロータンク20の吸水口21とカランの位置がずれている手洗い部であっても、カランの下に載置できるようにすることができる。
【0036】
【実施例】
試験例1、2
ヘッドスペースの効果を調べるため、横断面が角を丸めた矩形形状の筒形の薬液タンクで満容量110mLのものに80mLの薬剤を充填し、使用開始時のヘッドスペースを30mLにした薬液供給具(試験例1)と、同様の形状で満容量90mLの薬液タンクに80mLの薬剤を充填し、使用開始時のヘッドスペースを10mLにした薬液供給具(試験例2)を作製した。
【0037】
この場合、薬剤Aとしては、表1の組成の青色薬剤(粘度80mPa・s(20℃))を使用した。
【0038】
【表1】

Figure 2004132109
【0039】
各試験例の薬液供給具を水洗トイレの手洗い部に載置し、実使用に供し(水温21〜26℃、気温21〜28℃、水温と気温の差0〜3℃)、所定のフラッシュ回数における薬液供給具内の液残量を測定した。また、トイレの水封部に溜まった薬剤濃度を測定するため、水封部の液の吸光度を測定した。なお、吸光度の測定には、分光光時計(UV−2500PC、島津製作所)を用いた。結果を図6に示す。
【0040】
図6の結果から、ヘッドスペースが10mL(試験例2)の場合には、フラッシュ回数約300でトイレの水封部の薬剤濃度が使用開始時の1/2以下になっているにもかかわらず、薬液供給具内には約70gの液残量があり、フラッシュ回数500になっても液残量が殆ど減らないのに対し、ヘッドスペースが30mL(試験例1)の場合には、フラッシュ回数を重ねるのに伴って薬液供給具内の液残量が減っていることがわかる。
【0041】
したがって、使用開始時に薬液タンクにヘッドスペースを設けることにより、薬液タンク内に残液として希釈液が残らないようにする効果のあることがわかる。
【0042】
【発明の効果】
本発明によれば、水洗トイレの手洗い付きロータンクの手洗い部に載置することによりロータンク内に薬剤を供給する薬液供給具において、その使用を重ねた場合に、薬液タンク内に十分な薬効のない希釈液が残ることを防止できる。

It relates to a supply tool.
[0002]
[Prior art]
Patented as a chemical liquid supply device that is placed on the hand washing section of a low tank with hand washing in a flush toilet and mixes chemicals (fragrances, detergents, bactericides, etc.) with water supplied from the caran above the hand washing section 2. Description of the Related Art A chemical supply device for a flush toilet described in Document 1 is known. In this medicine supply device, a medicine lead-out hole is provided at the bottom of a medicine tank (drug container) containing a liquid medicine, and the medicine is led out of the lead-out hole into an impregnating body to be impregnated. From the water supplied to the hand-washing unit from below, so that the chemical contained in the impregnated body is dissolved in the water and flows down into the raw tank.
[0003]
[Patent Document 1] Japanese Patent Application Laid-Open No. 2001-342666
[Problems to be solved by the invention]
The above-described chemical supply device is structurally complicated, and the manufacturing cost is high. On the other hand, as shown in FIG. 5, a chemical solution supply device 100x having a simpler mechanism includes a chemical solution tank 1 for storing a liquid medicine A and a cap 3 attached to a bottom opening 2 of the chemical solution tank 1. It is conceivable that the cap 3 is provided with a chemical solution supply nozzle 4 and a foot 6. The medicine A is held in the tip opening 5 of the chemical liquid supply nozzle 4 by the surface tension and the inside of the chemical liquid tank 1 being in a weak negative pressure state.
[0005]
This chemical solution supply device 100x is placed on the water inlet 21 of the hand washing unit 20 of the low tank, and when water W is supplied from the curan to the hand washing unit 20 as shown by an arrow by flushing the water of the flush toilet, The water W flows down into the low tank so as to wash the chemical liquid supply nozzle 4 holding the chemical A. Therefore, according to the chemical liquid supply device 100x, it is possible to mix the chemical A into the low tank every time water is supplied from the curran with a simple mechanism.
[0006]
The inside of the chemical tank 1 becomes negative pressure in accordance with the amount of the medicine A supplied into the raw tank, but the diluent, water or air of the medicine adhering to the distal end opening 5 of the chemical supply nozzle 4 is exposed to the tip. Since the liquid medicine tank 1 immediately enters the liquid medicine tank 1 through the opening 5, the inside of the liquid medicine tank 1 returns to a weak negative pressure state. Thereafter, each time water is supplied from the curan, this action is repeated, the medicine A is mixed into the raw tank, and the medicine diluent, water or air is replaced in the medicine tank 1.
[0007]
However, according to the chemical solution supply device 100x, since the water is replaced in the chemical solution tank 1 as described above, when the use of the chemical solution supply device 100x is repeated, the medicine A in the chemical solution tank 1 gradually decreases. It may be diluted and a diluent that does not have sufficient medicinal effect may remain. If such a diluting liquid remains in the chemical liquid tank 1, there is a problem that the chemical liquid supply device 100x is continued to be used even though there is no sufficient medicinal effect because there is apparently a liquid agent in the chemical liquid tank 1. Occurs. In addition, it is common practice to color the medicine mixed into the raw tank in blue, green, etc. so that colored water accumulates in the water seal portion of the toilet. In this case, the water in the water seal portion has a concentration of the drug. Is colored even if diluted to about 5%, it is not possible to judge whether the residual liquid in the chemical tank A has sufficient medicinal effect even by the color of the water in the water seal portion. .
[0008]
On the other hand, the present invention provides a chemical solution supply device that supplies a medicine into the low tank by being placed on a hand washing section of a low tank with hand wash of a flush toilet, and when the use of the chemical solution supply device is repeated, sufficient medicinal effect is obtained. The purpose is to ensure that no diluent remains in the chemical tank.
[0009]
[Means for Solving the Problems]
The inventor of the present invention determines whether or not a diluent without sufficient medicinal effect remains in the chemical solution tank when the chemical solution supply device is repeatedly used, by determining whether the flushing water in the flush toilet at the start of use of the chemical solution supply device. It has been found that it is important to increase the amount of decrease in the amount of medicine per time, and for that purpose, it is effective to increase the head space in the medicine tank at the start of use of the medicine supply device.
[0010]
That is, the present invention is a chemical solution supply device comprising a chemical solution tank containing a liquid chemical and a cap attached to the bottom opening of the chemical solution tank, and supplying the chemical from the opening of the cap to the low tank with hand washing of a flush toilet. Thus, the present invention provides a chemical solution supply device having a mechanism for increasing the head space of a chemical solution tank.
[0011]
Here, the head space refers to a space existing in an upper part in the chemical solution tank.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. In the drawings, the same reference numerals indicate the same or equivalent components.
[0013]
FIG. 1 is a perspective view (a) of a chemical solution supply device 100A according to one embodiment of the present invention, and a cross-sectional view (b) of a used state thereof. FIG. 2 is a cross-sectional view illustrating a method of assembling the chemical solution supply device 100A. FIG.
[0014]
The chemical solution supply device 100A includes a chemical solution tank 1 for storing a liquid medicine A such as a fragrance for toilet, a cleaning agent, and a germicide; a cap 3 attached to a bottom opening 2 of the chemical solution tank 1; A top plate 10 is provided on the top 7 so as to be detachable.
[0015]
The chemical liquid tank 1 can be provided in a form filled with the medicine A and the bottom opening 2 sealed with a seal member 8 as shown in FIG.
[0016]
The cap 3 is provided with a chemical solution supply nozzle 4 and a foot 6 integrally with the cap 3, and inside the cap 3, a medicine container 11 is formed as a head space increasing mechanism. A distal end opening 5 is formed at the distal end of the chemical liquid supply nozzle 4, where the chemical A is held by the surface tension and a weak negative pressure in the chemical liquid tank.
[0017]
The chemical liquid supply device 100A has a very simple configuration, and the chemical liquid tank 1, the cap 3, and the top plate 10 can be easily manufactured by plastic molding. Therefore, the chemical solution supply device 100A can be obtained at low cost.
[0018]
As the medicine A, one adjusted to a viscosity of 5 to 1000 mPa · s (20 ° C.) is used, and the hole diameter of the distal end opening 5 of the medicine supply nozzle 4 is preferably 1 to 5 mm. If the viscosity of the drug A exceeds 1000 mPa · s, or if the hole diameter of the distal end opening 5 is smaller than 1 mm, it becomes difficult to discharge the drug A from the drug solution tank 1 to the tip of the drug solution supply nozzle 4. Conversely, if the viscosity of the medicine A is lower than 5 mPa · s or the hole diameter of the tip opening 5 is larger than 5 mm, the medicine A easily leaks from the tip opening 5 excessively.
[0019]
As a method of assembling the chemical liquid supply device 100A, first, as shown in FIGS. 2A and 2B, the sealing member 8 is peeled off from the bottom opening 2 of the chemical liquid tank 1, and the cap 3 is fitted thereto. The top plate 10 is fitted to the top 7 of the medicine tank 1. Next, as shown in FIG. 2C, the chemical solution tank 1 is turned upside down. As a result, the medicine A in the medicine tank 1 flows into the medicine container 11 in the cap 3, a head space HS is formed in the medicine tank 1, and the use of the medicine supply device 100A is achieved.
[0020]
As a method of using the chemical solution supply device 100A, the chemical solution supply device 100A assembled as shown in FIG. 2C is placed under the callan of the hand washing section 20 of the low tank with a hand wash of a flush toilet, and the chemical solution supply nozzle 4 absorbs water. It is inserted into the mouth 21 (FIG. 1 (b)).
[0021]
After placing the medicine ejection container 100A on the hand washing section 20, the water in the flush toilet is flushed and water is supplied from the caran. As shown in FIG. To flow into the hand washing section 20 along the side surface of the chemical solution tank 1, flow into the water suction port 21, further flow down along the chemical solution supply nozzle 4, and flow so as to wash the opening 5 at the front end thereof. Get in. Therefore, the medicine A held in the distal end opening 5 is eroded by the water W and mixed into the raw tank.
[0022]
When the supply of water from the curan stops, the flow of water that exposes the medicine A held in the distal end opening 5 of the chemical liquid supply nozzle 4 stops, and the supply of the medicine A into the low tank stops. The inside of the chemical tank 1 becomes negative pressure in accordance with the amount of the medicine A supplied into the raw tank, but the diluent, water or air of the medicine adhering to the front end opening 5 is immediately discharged from the front end opening 5 by the chemical liquid. Since the liquid enters the tank 1, the inside of the chemical liquid tank 1 returns to a weak negative pressure state, and the chemical A is held in the distal end opening 5 of the chemical liquid supply nozzle 4 in the same manner as before the water supply from the curran.
[0023]
Thereafter, this operation is repeated each time water is supplied from the curan.
[0024]
Here, when the water temperature of the water W is lower than the room temperature of the toilet, the air in the head space HS in the chemical liquid tank 1 is cooled by the water supply from the callan, and gradually returns to the room temperature when the water supply from the callan stops. Accordingly, during this time, the air in the head space HS expands, and the medicine A is also discharged by this, so that the amount of liquid in the chemical tank 1 is surely reduced without water W being mixed into the chemical tank 1. Become.
[0025]
On the other hand, when the water temperature of the water W is higher than the room temperature of the toilet, the head space HS in the chemical solution tank 1 is heated when water is supplied from the caran, and the air in the head space HS expands, whereby the medicine A is discharged. You. At the time of discharging the medicine A, the inside of the chemical tank 1 is heated and pressurized, so that the amount of water W entering the chemical tank 1 is small. Therefore, also in this case, the liquid amount in the chemical liquid tank 1 is reduced.
[0026]
As described above, in the chemical liquid supply device 100A, since the medicine container 11 is formed in the cap 3, the head space HS is formed in the chemical liquid tank 1 at the start of use. In contrast to the case where the head space is not formed at the start of use, due to the difference between the water temperature and the room temperature, the amount of the medicine discharged from the chemical liquid tank 1 in a state where the water W does not enter the chemical liquid tank 1 is increased. Can be. Therefore, according to the chemical liquid supply device 100A, even if the residual liquid in the chemical liquid tank 1 becomes small due to repeated use, the residual liquid is the medicine A having a sufficient medicinal effect, and the dilution without the medicinal effect is performed. The liquid is prevented from remaining in the chemical tank 1.
[0027]
On the other hand, if there is no head space in the chemical liquid tank 1 at the start of use, the medicine A in the chemical liquid tank 1 is replaced with water only when water is supplied from the curan, and the chemical A is diluted. In addition, the liquid amount in the chemical liquid tank 1 is hardly reduced, and the head space does not increase even if the liquid is repeatedly used. Further, when water is mixed into the chemical liquid tank 1, the liquid property in the chemical liquid tank changes, the surface tension increases, and it becomes more difficult to discharge the chemical A due to the expansion of the air in the head space. Therefore, when used repeatedly, a diluent having no medicinal effect remains in the chemical liquid tank 1.
[0028]
If the size of the head space HS at the start of use is too large, the filling efficiency of the drug A is poor, and if it is too small, the effect of preventing the diluent from remaining as a residual liquid cannot be obtained. Is preferably set to 11 to 50%. Therefore, it is preferable that the volume of the medicine container 11 be determined so that such an HS is formed.
[0029]
In addition, in the chemical liquid supply device 100A, the top plate 10 prevents the water of the currant from directly hitting the chemical liquid tank 1, thereby reducing the supply amount of the chemical A from the chemical liquid tank 1 to the fluctuation of the water temperature or the temperature. Regardless, stabilize. At the start of use of the chemical liquid supply device 100A, as described above, the difference between the water temperature and the air temperature is positively used, and the chemical A is discharged from the chemical liquid tank 1 by the expansion of the air in the head space HS. However, once the head space becomes about 50% or more of the volume of the chemical tank, even if the supply amount of the chemical A from the chemical tank 1 is not increased by utilizing the difference between the water temperature and the air temperature, It is possible to prevent the diluent having no medicinal effect from remaining in the chemical liquid tank 1. Therefore, in order to stabilize the supply amount of the medicine A from the medicine tank 1, it is preferable to provide the top plate 10. In addition, since water supplied from the curran flows radially along the top plate 10 and has a beautiful veil appearance of water, it is preferable to provide the top plate 10 from the viewpoint of improving the usability of the chemical solution supply tool.
[0030]
In the present invention, the mechanism for increasing the head space at the start of use of the chemical solution supply tool is not limited to the cap, and may be provided in the chemical solution tank.
[0031]
For example, FIGS. 3A and 3B are a perspective view (a) and a cross-sectional view (b) of a chemical solution supply device 100B in which a bellows portion 12 is provided on a side wall of the chemical solution tank 1 as a headspace increasing mechanism.
[0032]
As shown in FIG. 4 (a), the chemical solution tank 1 is provided in a form in which the bellows portion 12 is filled with the drug A in a contracted state and the bottom opening 2 is sealed with a seal member 8, as shown in FIG. You.
[0033]
As a method of assembling the chemical solution supply device 100B, first, as shown in FIGS. 4A and 4B, the sealing member 8 is peeled off from the bottom opening 2 of the chemical solution tank 1, the cap 3 is fitted therein, and the bellows portion Extend 12 Further, the top plate 10 is fitted to the top 7 of the medicine tank 1. Next, as shown in FIG. 4C, the chemical solution tank 1 is turned upside down. Since the bellows portion 12 of the chemical liquid tank 1 is extended, the head space HS is formed in the chemical liquid tank 1 by turning the chemical liquid tank 1 upside down, and the chemical liquid supply device 100B is used. In addition, as a method of fixing the bellows portion 12 in a stretched state, for example, the strength of the bellows portion is increased or the bellows portion is flattened so that the stretched shape of the bellows portion does not restore the original contracted shape. Are provided.
[0034]
The chemical solution supply device 100B thus assembled is used in the same manner as the above-described chemical solution supply device 100A. The chemical supply device 100B can also prevent the diluent having no medicinal effect from remaining in the chemical liquid tank 1 when used repeatedly.
[0035]
The above-described chemical solution supply devices 100A and 100B can be placed on the hand washing section where the curan is located on the water intake port 21 of the raw tank 20, but in the present invention, the chemical solution supply nozzle 4 is formed shorter with respect to the foot 6. By doing so, even in the hand washing section in which the position of the water intake port 21 of the low tank 20 and the position of the curan are displaced, it can be placed under the curan.
[0036]
【Example】
Test examples 1 and 2
In order to investigate the effect of headspace, a chemical liquid supply tool with a rectangular cylindrical cross-section with rounded corners filled with 80 mL of a drug filled to 110 mL and filled with a headspace of 30 mL at the start of use. A drug solution supply device (Test Example 2) was prepared by filling a drug solution tank having a capacity of 90 mL in the same shape as in (Test Example 1) with a capacity of 80 mL and a head space at the start of use of 10 mL.
[0037]
In this case, as the medicine A, a blue medicine having a composition shown in Table 1 (viscosity of 80 mPa · s (20 ° C.)) was used.
[0038]
[Table 1]
Figure 2004132109
[0039]
The chemical solution supply device of each test example was placed on the hand washing section of the flush toilet and used for actual use (water temperature 21 to 26 ° C., air temperature 21 to 28 ° C., difference between water temperature and air temperature 0 to 3 ° C.), predetermined number of flushes Was measured for the remaining amount of the liquid in the chemical supply device. Further, in order to measure the concentration of the drug accumulated in the water seal portion of the toilet, the absorbance of the liquid in the water seal portion was measured. In addition, the spectrophotometer (UV-2500PC, Shimadzu Corporation) was used for the measurement of the absorbance. FIG. 6 shows the results.
[0040]
From the results in FIG. 6, when the head space is 10 mL (Test Example 2), even though the flushing frequency is about 300, the drug concentration in the water seal portion of the toilet is not more than 1/2 that at the start of use. However, there is about 70 g of liquid remaining in the chemical solution supply device, and the remaining liquid hardly decreases even when the number of flushes reaches 500, whereas when the head space is 30 mL (Test Example 1), the number of flushes It can be seen that the remaining amount of the liquid in the chemical liquid supply tool is reduced as the numbers are overlapped.
[0041]
Therefore, it can be seen that providing a head space in the chemical solution tank at the start of use has an effect of preventing the diluent from remaining in the chemical solution tank.
[0042]
