【0001】
【発明の属する技術分野】
本発明は、液体ボトル内の液体製剤を支持部に供給し、その支持部から液体製剤の有効成分を外部に供給する液体供給装置に関する。
【0002】
【従来の技術】
従来、水洗トイレの貯水タンクの蓋上面の水受け部に配置されて使用される、所謂オンタンク式の液体供給装置が提案されている。
【0003】
【発明が解決しようとする課題】
液体供給装置には、使いやすく、長期にわたって液体製剤を安定供給し続けるようにすることが求められているが、この観点において従来のものには、更なる改善が望まれていた。
本発明は、このような事情に鑑みてなされたもので、その目的は、使いやすく、長期にわたって液体製剤を安定供給できる液体供給装置を提供することにある。
【0004】
【課題を解決するための手段】
本発明の上記目的は、下記構成によって達成される。
(1) 液体製剤を収容した液体ボトルと、前記液体ボトルの所定箇所に通気口を形成する通気口形成手段とを備え、水洗トイレの貯水タンクの蓋上面の水受け部に配置されて使用される液体供給装置において、
前記液体ボトルを支持する底壁と周壁とを備え前記周壁に通水口を形成された支持部を更に備え、
前記支持部に支持された前記液体ボトルの下方に液体製剤を流出させる流出口が形成され、
前記流出口は、使用前、中栓により閉塞されており、
前記中栓は、使用開始時に、前記底壁の上面に上方に向けて装着された突出ピンに押圧されることで前記液体ボトルの内方に離脱され、
更に、前記支持部の前記底壁の上面に吸液部材が装填され、前記突出ピンが前記吸液部材を貫通し、前記突出ピンの周りには、前記突出ピンより低い円筒状の支持壁が設けられ、前記突出ピンと前記円筒状の支持壁との間に前記液体製剤が供給されることで、前記吸液部材に前記液体製剤が供給され、
更に、前記円筒状の支持壁に支持された前記液体ボトルの前記流出口の下端と、前記吸液部材の上面との間に流水用の間隙が形成されることにより、手洗い用の水を前記流出口付近にあてて前記流出口で前記液体製剤が乾燥してつまることを防止することを特徴とする液体供給装置。
(2) 前記通気口形成手段は、軸部の外周面に通気用の溝を有し、前記液体ボトルの外部から液体ボトルの壁面に挿通される穿孔部材である前記(1)に記載の液体供給装置。
【0005】
上記構成の液体供給装置によれば、支持部に支持された液体ボトルの下方に液体製剤を流出させる流出口が形成された状態で、通気口形成手段によって液体ボトルの液体製剤の液面より上方の箇所に外部と連通する通気口を形成することで、液体ボトル内の圧力を適度に調整でき、流出口から液体製剤をスムーズに流出させることができる。すなわち、液体製剤の流出量が変動せず、流出量を一定に保つことができる。したがって、長期にわたって液体製剤を安定供給することができる。
また、通気口が液体供給装置の使用時に形成されるので、製品流通時や使用前に通気口を通じて液体製剤が漏れることもない。
通気口は、液体(水等)は通さず気体は透過する通気シート(微多孔性膜)で塞がれていてもよい。また、液体ボトルの一部若しくは全部を、気体を透過する微多孔性素材等で形成し、その液体ボトルを包装シート(フィルム)で覆ってもよい。この場合、包装シートが通気口形成手段として機能する。
【0006】
液体ボトルの材質、形状は特に限定されず、液体製剤を安定に収容できるものであればよく、その材質として、ポリエチレン、ポリエチレンテレフタレート、ポリプロピレン、ガラス、陶器等を例示できる。
液体ボトルは、液体ボトルに設けられた開口を塞ぐ中栓を備えて、その中栓に液体製剤を流出するための流出口が形成される構成とすることができる。中栓に流出口を予め設けておいてもよいが、使用時に中栓に流出口が形成されても良い。
支持部は、その内部に、液体製剤を保持する保持担体を備えた構成とすることができる。保持担体として、吸液マットや、吸液性は乏しいが液保持用の溝等を設けた保持マットを例示できる。吸液マットの材質としては、パルプ、レーヨン、ポリエステル、ポリエチレン、ポリプロピレンなどの成形物、或いはこれらを用いた不織布等を例示できる。その他、支持部の底壁に液保持用の溝を設けるなどして、支持部の底壁を保持担体として機能させることもできる。
液体製剤としては、例えば、界面活性剤及び増粘剤、香料、溶剤(水、アルコール、ポリエチレングリコール、ジプロピレングリコール、3−メトキシ−3−メチルブタノール(商品名ソルフィット クラレ(株)製)、濃グリセリン)、着色剤等を含むものを採用でき、更に洗浄、防汚、漂白、撥水、撥油、芳香、消臭、除菌、防黴、殺菌、忌避、防虫、殺虫等の成分を配合することができる。液体製剤は、液体ボトルから流出するものであればよく、ゲル状、ジェル状、ゾル状のものでもよい。
上記界面活性剤としては、代表的にはアニオン系界面活性剤、ノニオン系界面活性剤の少なくとも一方を挙げることができるが、実施可能なかぎりそれらに限定されない。
【0007】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて詳しく説明する。図1に示す第1実施形態の液体供給装置10は、水洗トイレ用貯水タンクの上面(蓋)に形成された凹状の水受け部91に設置されて使用される。水受け部91には、貯水タンク内に連通した注水孔92が設けられている。
【0008】
液体供給装置10は、液体製剤Lを収容した液体ボトル11と、液体ボトル11を支持する有底円筒状の支持部15とを備えている。液体ボトル11は、支持部15にセットした状態における上部が中空半球状(球面部11a)になっており、下部が上部より小径の円筒状(円筒部11b)になっている。液体ボトル11は、液体製剤Lの残量を視認できるように透明ないし半透明にすることができる。液体ボトル11の円筒部11bは、支持部15内に収まる。液体ボトル11の最下部には開口が設けられている。その開口は、プラスチックやゴム等の弾性体からなる中栓12によって塞がれている。
【0009】
本実施形態では、液体ボトル11の球面部11aの液体製剤Lの液面より上方の箇所(頂部付近)に、外壁面に一体的に突起部17が設けられている。突起部17は、図に示すように棒状とすることができるが、特にこれに限定されない。
【0010】
本実施形態では、中栓12として、2部材からなるものが採用されている。中栓12は、液体ボトルの円筒部11bに外嵌された外周部12a及び内嵌された内周部12bからなる栓本体と、液体ボトル11の内部空間側から内周部12bに内嵌された密閉部12cとを備えている。
【0011】
支持部15は、底壁15aと周壁15bとを有している。周壁15bの下部には、周方向に間隔をあけて複数の通水口16bが設けられている。底壁15aにも、複数の通水口16aが設けられており、その通水口16aを塞ぐか適度に開口するように吸液マット18が敷かれている。
吸液マット18を敷く代わりに、支持部15の底壁15aの内面(図では上面)に、多数のスジ、小突起或いは溝を、網目状、放射状或いはリング状に設けて、底壁15aに液体製剤を適度に保持できるようにすることで、装置のコンパクト化を図ってもよい。
【0012】
支持部15の底壁15aの中央部上面には、上方へ立ち上がって、吸液マット18を貫通した突出ピン14が設けられている。突出ピン14の周りには、突出ピン14より低い円筒状の支持壁14aが設けられている。突出ピン14と支持壁14aとの間に、液体製剤Lを注水孔92へ導くために、底壁15aには孔があいている。
一方、支持部15の底壁15aの中央部下面には、水受け部91の注水孔92に挿通されて、液体供給装置10を水受け部91上で位置決めするための、位置決め部材19が設けられている。なお、位置決め部材19の形態はこれに限定されず、他の形態でもよい。
【0013】
液体供給装置10の使用時には、図1に示す状態から液体ボトル11を押し下げて、中栓の密閉部12cに、支持部15に備えられた突出ピン14を当接させる。そして、更に液体ボトル11を押し下げることで、突出ピン14によって中栓の密閉部12cを突き出して栓本体から外す。
【0014】
そして、図2に示すように、突起部17を折り倒すことで液体ボトル11の壁面の一部を破いて、通気口17aを形成する。これで、液体供給装置10が使用可能となる。このときの、密閉部12cが外れることで形成された中栓12の流出口12dの下端と、吸液マット18の上面との隙間Sは、0.5〜10mm程度、より好ましくは1〜5mm程度とするのが良い。隙間Sをこのような所定範囲内とすることで、手洗い用の水を流出口12d付近に当てることができるので、流出口12dで液体製剤Lが乾燥してつまることを確実に防止できる。また、隙間Sをあけることで、吸液マット18から液体ボトル11へと手洗い用の水や液体製剤が逆流することも確実に防止できる。
【0015】
手洗い用の水が水受け部91に供給されると、水は、通水口16bを通じて吸液マット18に触れる。吸液マット18には、液体製剤Lが含浸されており、その含浸された液体製剤が、吸液マット18に触れた水に混合される。液体製剤を混合された水が、支持部の底壁15aの通水口16aを通って、注水孔92に流入する。
保持した液体製剤Lを洗い流された吸液マット18には、液体ボトル11から液体製剤Lが順次供給される。その際、液体ボトル11内の液面より上方の内部空間が通気口17aを介して外部と連通しているので、内部空間が負圧になることはなく、液体製剤Lがスムーズに流出される。
【0016】
以上のような構成の液体供給装置10によれば、液体製剤Lの流出量が変動せず、また水が液体ボトル11内に逆流するのを防ぐことができるので、流出量を一定に保つことができる。したがって、長期にわたって液体製剤Lを安定供給することができる。
また、通気口17aが液体供給装置10の使用時に形成されるので、製品流通時や使用前に通気口を通じて液体製剤Lが漏れることもない。さらに、突起部17は、構造が簡単で、液体ボトル11の成形時に同時に成形できるので、製造が容易である。
【0017】
図3に、第2実施形態である液体供給装置20の要部を示す。なお、以下に説明する実施形態は、第1実施形態とは異なる通気口形成手段を採用したもので、その他の構成は第1実施形態と同様とすることができる。
第2実施形態である液体供給装置20は、液体ボトルの上部21aの壁面に、注射針のような管体27が挿通される。管体27内の貫通孔27aが通気口として機能する。管体27は、液体ボトル内の液面より上方の内部空間と外部とを連通する。管体27は、液体ボトル内に挿通される先端が、鋭利形状になっている。
【0018】
図4(A)に、第3実施形態である液体供給装置30の要部を示す。液体供給装置30は、液体ボトルの上部31aの壁面に、穿孔部材37が挿通される。穿孔部材37は、液体ボトル内の液面より上方の内部空間と外部とを連通する。
図4(B)は、穿孔部材37の拡大側面図である。穿孔部材37は、軸部39と、軸部39より大径の頭部38とを有して、押しピン形状を呈している。液体ボトルの壁面31aに挿通される軸部39の外周面には、軸方向に沿って複数の通気用の溝39aが設けられている。軸部39の先端は鋭利形状になっている。頭部38の、壁面31aに相対する面には、壁面31aと頭部38との間に隙間を確保するための突起38aが設けられている。この壁面31aと頭部38との間の隙間と、軸部39の溝39aとを通じて、液体ボトル内の液面より上方の内部空間と外部とが連通される。
図示しないが、穿孔部材37の頭部38の壁面31aに相対する面に突起38aを設ける代わりに、通気用の溝を設けてもよい。この場合、その頭部38の溝と軸部39の溝とを通じて、液体ボトル内の液面より上方の内部空間と外部とが連通される。
【0019】
図5(A)に、第4実施形態である液体供給装置40の要部を示す。液体供給装置40は、液体ボトルの上部41aの壁面に通気用の開口47aが設けられ、その開口47aがシール部材47によって塞がれている。
図5(B)に示すように、例えば、開口47aを円形状に形成し、シール部材47を開口47aより大径の円形状に形成することができる。シール部材47は、例えば、壁面41aに剥離可能に接着することができる。
【0020】
液体ボトルの壁面41aの、シール部材47を接着される領域(開口47aの周囲の領域)には、撥水処理を施すことが好ましい。こうすることで、不意にシール部材47が剥がれたり、液体製剤Lが漏れたりすることを確実に防止できる。また、手洗い水の表面張力によって開口47aが塞がれるのを確実に防止できる。
撥水処理の方法に制限はないが、例えば、シリコーン系撥水剤、フッ素系撥水剤又は撥水塗料等を壁面41aに塗布する方法を採用できる。
【0021】
図6(A)は、第5実施形態である液体供給装置50の要部を示す。液体供給装置50は、液体ボトルの上部51aの壁面に通気用の開口57aが設けられ、その開口57aがシール部材57によって塞がれている。
図6(B)に示すように、本実施形態のシール部材57は撥水シート59及び密閉シート58の、2部材からなっている。撥水シート59は、例えば円環状に形成することができ、中央開口59aの大きさは、液体ボトルに備えられた開口57aの大きさと同等にすることができる。撥水シート59は、密閉シート58に相対する面に撥水処理が施されている。密閉シート58は、例えば、撥水シート59の中央開口59aより大径の円形状に形成することができる。密閉シート58の外径は、撥水シート59の外径と同等かそれより小さくすることができる。密閉シート58は、撥水シート59に接着される。
この液体供給装置50の使用時には、密閉シート58のみを剥離すればよい。
【0022】
なお、本発明は、前述した実施形態に限定されるものではなく、適宜な変形、改良等が可能である。
例えば、シール部材として、剥離可能なものの代わりに、破断可能なものを用いてもよい。
流出口を形成するために、上記の実施形態のもの以外の構造を採用してもよく、例えば、液流出用の溝を備えた柱状部材を中栓に挿通することで、柱状部材の溝を流出口として機能させてもよい。
【0023】

The protrusion 17 can be shaped like a rod as shown in the figure, but is not particularly limited thereto.
[0010]
In the present embodiment, the inner plug 12 is composed of two members. The inner stopper 12 is fitted into the inner peripheral portion 12b from the inner space side of the liquid bottle 11 and the stopper body including the outer peripheral portion 12a and the inner peripheral portion 12b that are fitted inside the cylindrical portion 11b of the liquid bottle. And a sealed portion 12c.
[0011]
The support part 15 has a bottom wall 15a and a peripheral wall 15b. A plurality of water inlets 16b are provided in the lower part of the peripheral wall 15b at intervals in the circumferential direction. The bottom wall 15a is also provided with a plurality of water inlets 16a, and a liquid-absorbing mat 18 is laid so as to close or moderately open the water outlets 16a.
Instead of laying the liquid-absorbing mat 18, a large number of stripes, small protrusions or grooves are provided on the inner surface (upper surface in the figure) of the support portion 15 in a mesh shape, a radial shape or a ring shape. The apparatus may be made compact by allowing the liquid preparation to be appropriately held.
[0012]
On the upper surface of the central portion of the bottom wall 15 a of the support portion 15, a protruding pin 14 that rises upward and penetrates the liquid absorbent mat 18 is provided. A cylindrical support wall 14 a lower than the projecting pin 14 is provided around the projecting pin 14. A hole is formed in the bottom wall 15a between the protruding pin 14 and the support wall 14a in order to guide the liquid preparation L to the water injection hole 92.
