Description

【０００１】
【発明の属する技術分野】
本発明は液体計量塗布栓に関する。
【０００２】
【従来の技術】
この種の塗布栓として、本出願人は既に計量操作を簡易とした液体計量塗布栓を提案している（特願2001-55165）。
【０００３】
この塗布栓は、内部を計量室としたケーシングの下部周縁部より容器体の口頸部外周に嵌合させた装着筒を垂設するとともに、ケーシング底壁を貫通して有底のシリンダを垂設し、且つ、計量室内に突出したシリンダの外側を環状の計量凹部とした本体と、シリンダ内に嵌合させたピストンを外周より突設して上方付勢状態に設けるとともに、ケーシングの頂壁に設けたノズル筒へ上端を突出しての液密な嵌着が可能に、且つ、突出部分の押し込みによる連通が可能に設けた棒栓と、該棒栓を押し込んでノズル筒に密嵌した押圧突起を頂壁裏面より垂設するとともに、着脱可能に装着したキャップとを備え、該キャップ装着時には、シリンダの所定位置に穿設した連通孔を介して容器体内と計量室内とが連通し、キャップ離脱時には容器体内と計量室内とが遮断される如くピストンと連通孔を配設してなるものである。
【０００４】
上記塗布栓は、キャップ嵌合状態で容器体を倒立させた後、正立に戻すだけで計量でき、該計量状態からキャップを外すだけで計量液体を容器体内液体から分離し、計量液体だけを塗布し尽くすことができ、また、キャップ取り外し状態においては容器体が倒れる等してもノズル筒上面から上方突出する棒栓上面を押し下げない限り計量液体が漏れることがない等の優れた効果を発揮するものである。
【０００５】
【発明が解決しようとする課題】
この種塗布栓では、上記した如き取り扱い易さを備えているものの、その構造上必ずキャップを必要として、また、塗布の都度キャップの螺着，螺脱を行わなければならない。
【０００６】
本発明は上記した点に鑑みなされたもので、キャップを必ず必要とする構成上の制限がなく、しかも更に取り扱い操作を更に簡略化した優れた液体計量塗布栓を提案することを目的とするものである。

【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
【００１５】
図面に示す如く、本発明の液体計量塗布栓１は、容器体２の口頸部３に装着して使用する液体計量塗布栓であって、液導入孔４を介して容器体２内と連通する計量室Ａを備え、計量室Ａ内部には計量凹部Ｂを有している。また、計量室Ａ上端のノズル筒５へ上端を突出しての液密な嵌着が可能に且つ突出部分の押し込みによる連通が可能に上方付勢状態で設けた棒栓６を備えている。そして、全体を、口頸部３に回動を防止して嵌着固定した固定部Ｄと、該固定部に回動可能に嵌合させた可動部Ｅとから構成している。
【００１６】
また、上記液導入孔４を、上記固定部Ｄの容器体２内と連通する固定壁部に穿設した外透孔4aと、上記可動部Ｅの計量室Ａ内と連通し且つ上記固定壁部と摺動可能に密接する可動壁部に穿設した内透孔4bとで構成し、上記可動部Ｅの回動により外透孔4aの位置に対する内透孔4bの位置を移動させて液導入孔４を開閉する如く構成している。
【００１７】
そして、倒立状態で液導入孔４から液を導入後正立させて計量凹部Ｂに液を計量するとともに、過剰の液を容器体内に戻し、次いで液導入孔４を閉塞した後棒栓６を押し込んで計量液を塗布する如く構成している。
【００１８】
図１に示す実施例は、上記容器体２の口頸部３外周に回動を防止して嵌合した装着筒７より口頸部３上端開口を被覆する被覆板８を延設して容器体に液密に嵌着固定した固定部Ｄを備え、また、内部を上記計量室Ａとするとともに、下部周縁部より延設した回動筒９を固定部Ｄ外周に回動可能に嵌着し、且つ、上記可動壁部としての底壁の少なくとも中央部を上記固定壁部としての上記被覆板８上に摺動可能に密接させてなるケーシング10と、計量室Ａ上端の上記ノズル筒５へ設けた上記棒栓６とからなる可動部Ｅを備えている。
【００１９】
更に具体的には、固定部Ｄの装着筒７は、その内周下端部に突設した突条を口頸部３外周に突設した突条に乗り越え係合させて上方への抜け出しを防止するとともに、内面上端部より周方向多数突設した係合突起を口頸部３外周に周方向多数突設した係止突起と係合させて回動防止を図る廻り止め機構11を設けている。また、装着筒７の上端縁より、中央部に円筒状の***部8aを設けた被覆板８を延設するとともに、被覆板８裏面周縁部より垂設したシール筒12を口頸部３内周に密嵌させてこの部分からの液の漏出を防止している。更に、被覆板８の上面周縁部からは可動部Ｅの上記回動筒９を回動可能に係合させるための係合筒13を立設している。
【００２０】
可動部Ｅは、底壁10a 周縁部より周壁10b を立設するとともに、周壁上端縁より頂壁10c を延設してなるケーシング10を備え、上記係合筒13の外周に装着筒７と同様手段で抜け出しを防止し且つ回動可能に嵌合させた回動筒９を、周壁10b 外周下部よりフランジ14を介して延設するとともに、底壁10a 中央部下面を上記***部8a上面に摺動可能に密接して固定部Ｄに回動可能に装着している。また、底壁10a 裏面中央部より***部8aの外周に摺動可能に嵌合するシール筒17を垂設し、この部分の液密性を図っている。
【００２１】
また、周壁10b 上端縁より延設した頂壁10c 中央に短筒状のノズル筒５を設け、該ノズル筒５内に塗布口15を開口しており、ノズル筒５内周上端部には凹部16を周設している。そして、ケーシング10内を計量室Ａとして構成するとともに、上記底壁10a 上面中央部より上方へ区画筒18を立設し、その外方を計量凹部Ｂとして構成している。尚、ケーシング10は２部材で構成している。
【００２２】
棒栓６は、計量室Ａ内の下端周縁部に下端部を固定した螺旋バネ19の上端に下端部を一体に連結して上方付勢状態で設けており、塗布口15の周縁部の頂壁10c 裏面に係合させた下端部のスカート状部6aより柱状部6bを立設し、この柱状部6bをノズル筒５内面に摺動可能に密嵌させており、この柱状部6bの外周上部には、下端がノズル筒５内面上下方向中間部に至り、ノズル筒５上端レベルまで押し込んだ際に内外を連通させる連通溝20を設けている。
【００２３】
従って、図１に示す如く、棒栓６上端がノズル筒５より突出した状態では連通溝20形成部分下方の柱状部6bの密嵌により塗布口15は密閉されており、一方、棒栓６上端のノズル筒５より突出した部分をノズル筒５上端レベルまで押し込んだ際には連通溝20を介して計量室Ａ内と外部が連通する如く構成している。尚、この際上記凹部16の存在で、出口を広くして円滑な塗布を行える如く構成している。
【００２４】
また、液導入孔４は、上記区画筒18内方の被覆板８中央部分偏心位置に穿設した外透孔4aと、区画筒18内方の外透孔対応位置のケーシング底壁10a に穿設した内透孔4bとで構成している。図示例では左右一対の外透孔4aと、各外透孔4aと連通する左右一対の内透孔4bとを設けており、図２(a) に示す如く、常時は各外透孔4a及び内透孔4bが連通しており、可動部Ｅを回動することにより図２(b) に示す如く両者が離隔して液導入孔４が閉塞される如く構成している。
【００２５】
また、本発明では可動部Ｅの回動規制機構21を備えている。この回動規制機構21は、可動部Ｅの回動が、液導入孔４の開状態から閉状態へ至る間の所定幅の回動となる如く規制したもので、本実施例では、図３に示す如く、固定部Ｄの上記係合筒13上面所定位置に所定幅の切欠凹部22を形成するとともに、可動部Ｅの上記フランジ14裏面所定位置に切欠凹部22内を往復動可能な突起23を垂設し、この突起23が切欠凹部22の一側端面から他側端面に至るまでの可動部Ｅの回動を可能に構成し、この一側端面に於いて液導入孔４が開状態であり、他側端面に於いて液導入孔４が閉状態となる如く構成している。尚、図中24はキャップを示す。
【００２６】
上記の如く構成した液体計量塗布栓１を使用する場合について説明する。図１の状態では、液導入孔４が開口しており容器体２内と計量室Ａ内とが連通しており、また、塗布口15は棒栓６により閉塞されている。
【００２７】
そして、図１の状態から容器１を倒立させると、図４に示す如く、計量室Ａ内に容器体２内の液が液導入孔４を介して導入される。次いで、この状態から容器１を正立させると、図５に示す如く、計量凹部Ｂ内に液が計量され、残りは液導入孔４を介して容器体２内へ戻される。
【００２８】
次いで、可動部Ｅを所定方向に回動させて液導入孔４を閉塞した後、図６に示す如く、容器体２を倒立して被塗布部分25に対して棒栓６を押し付け計量液の塗布を行う。棒栓６の押し込みにより連通溝20を介して計量された液が塗布口15より塗布される。この際液導入孔４は閉塞されているため計量された液のみが塗布される。
【００２９】
図７に示す実施例は、容器体２の口頸部３外周に回動を防止して嵌合した装着筒７より口頸部３上端開口を被覆する被覆板８を延設するとともに、被覆板８中央部を下方に円筒状に凹ませた陥没部8bを設け、且つ容器体に液密に嵌着固定してなる固定部Ｄを備え、また、上記陥没部周壁26内周に回動可能に嵌合した摺動筒部28を底壁10a 中央部を貫通して垂設するとともに、陥没部8bとで区画された内部を計量室Ａとし、且つ、周縁部下部より延設した回動筒９を固定部Ｄ外周に回動可能に嵌着させてなるケーシング10と、計量室Ａ上端の上記ノズル筒５に設けた上記棒栓６とで構成した可動部Ｅを備えている。
【００３０】
更に具体的には、固定部Ｄはその装着筒７を上記図１の実施例と同様の手段で抜け出しを防止して、また、回動を防止して、口頸部３外周に嵌合させており、その上端縁より延設した被覆板８の中央部を円筒状に凹ませて円筒状の周壁26及び底壁27からなる陥没部8bを形成している。更に、被覆板８の外周縁部上面からは上記係合筒13を立設しており、下面からは上記シール筒12を垂設しており、上記固定壁部としての陥没部周壁26下端部に外透孔4aを穿設している。
【００３１】
また、可動部Ｅはその回動筒９を、上記図１の実施例と同様の手段で抜け出しを防止して係合筒13外周に回動可能に装着している。また、係合筒13外面上端と回動筒９内面上端との間に同様の回動規制機構21を備えており、摺動筒部28外方のケーシング底壁10a より起立した区画筒18により計量室Ａ内周縁部に環状に形成した計量凹部Ｂを備えている。更に、上記可動壁部としての摺動筒部28下端部外透孔対応位置に内透孔4bを穿設している。また、本実施例に於いて、固定部Ｄ及び可動部Ｅは、その成形上の理由によりそれぞれ２部材で構成している。その他は図１の実施例と同様の部分は同符号を付して説明を省略する。
【００３２】
上記の如く構成した液体計量塗布栓１を使用する場合は、図７乃至図10に示す如く、図１の実施例と実質的に同様の操作で塗布を行える。
【００３３】
図11に示す実施例は、図７の実施例において、摺動筒部28を底壁29を有する有底の摺動筒部28とし、また、固定部Ｄを１部材で形成している。この場合、外透孔4aを、図12に示す如く下端面からの切欠透孔として構成することにより１部材で容易に形成できる如く構成している。その他の構成は図７の実施例と同様であるため、同符号を付して説明を省略する。作用も同様である。
【００３４】
図13に示す実施例は、図７の実施例において、摺動筒部28を底壁29を有する有底の摺動筒部28とし、また、陥没部8bを、下端を開口した陥没部8bとして構成し、更に、固定部Ｄを１部材で形成している。この場合も図11の実施例と同様に外透孔4aを下端面からの切欠透孔として構成している。その他の構成は図７の実施例と同様であるため、同符号を付して説明を省略する。作用も同様である。
【００３５】
図15に示す実施例は、容器体２の口頸部３外周に回動を防止して嵌合した装着筒７より口頸部３上端開口を被覆する被覆板８を延設するとともに、被覆板８中央部を下方に円筒状に凹ませた陥没部8bを設け、且つ、容器体に液密に嵌着固定してなる固定部Ｄを備えている。
【００３６】
具体的には、第１部材D1と第２部材D2との二部材で固定部Ｄを形成しており、第１部材D1は、上記図１の実施例と同様の手段で抜け出しを防止し、また、回動を防止して口頸部３外周に装着筒７を嵌合させており、また、装着筒７上端より内方へ被覆板の一部を構成するフランジを延設するとともに、該フランジ内周縁に円筒状の支持筒外面を連結し、また、支持板下面より垂設したシール筒12を口頸部３内周に液密に嵌着している。更に支持板上面外周縁より係合筒13を立設している。
【００３７】
第２部材は、陥没部8bを形成する有底円筒部の上部外周を支持筒内周に嵌合させるとともに、円筒部上端縁より被覆板の一部を構成するフランジを外方へ延設し、その外周縁部を係合筒13内面に回動不能に係合している。また、被覆板８の周縁部上面からは係合シール筒30を立設するとともに、その内側陥没部外方の被覆板８に区画筒18を立設している。また、上記固定壁部としての陥没部周壁26の下端部に外透孔4aを穿設している。そして各部材の各フランジにより被覆板の水平部分を構成している。
【００３８】
また、固定部Ｄ外周に回動可能に嵌合させた回動筒９上端部より下端部を上記被覆板８上面周縁部に液密回動可能に係合させた周壁31を延設するとともに、該周壁31上端縁より頂壁32を延設し、且つ、上記被覆板８とで内部に計量室Ａを画成してなる本体33と、計量室Ａ上端の上記ノズル筒５に回動を防止して嵌合した上記棒栓６と、陥没部周壁26内周に摺動可能に嵌合させるとともに、上端部を棒栓６下部に液の流通が可能に連動させた摺動筒34とを備えた可動部Ｅを備えている。
【００３９】
具体的には、上記実施例１と同様の手段で抜け出しを防止し、また、同様の回動規制機構21を備えた装着筒７の外周に回動可能に嵌合させた回動筒９の上端より内方へフランジ14を延設し、該フランジ14内周縁を周壁31の外周下部に一体に連結している。周壁31の下端部内周は上記係合シール筒30外周に液密且つ回動可能に係合させている。
【００４０】
棒栓６は、下面より連結棒部6cを垂設した以外は図１の実施例に於ける棒栓６と基本的構成が同じであり、但し、図15及び図16に示す如く、本体33のノズル筒５内周上部より突設した案内突起35を連通溝20に上下動可能に嵌合させて本体33に対する回動を防止する如く構成している。案内突起35は連通溝20の数より少なくして、液の流通が可能に構成する。また、連結棒部6cは、図15及び図17に示す如く、係合突条36を側面に突設して、摺動筒34内周上端に突設した係止突起37間に上下動可能に嵌合させて回動筒９を回動させた際に棒栓６を介して摺動筒34が連動する如く構成している。また、上記可動壁部としての上記摺動筒34下端部の外透孔対応位置に内透孔4bを穿設している。
【００４１】
上記の如く構成した液体計量塗布栓１を使用する場合について説明する。正立状態から容器を倒立後再び正立させて計量凹部Ｂ内に液を計量する操作は、図18及び図19にある如く、基本的に図７の実施例と同様である。
【００４２】
図19の状態から可動部Ｅを所定方向に回動させて液導入孔４を閉塞する。この際、本体33を回動させると、案内突起35と連通溝20との係合により棒栓６が同様に回動し、また、棒栓が回動すると、係合突条36と係止突起37の係合により摺動筒34が回動する。最後は図20に示す如く同様に計量液の塗布を行う。
【００４３】
図21に示す実施例は、容器体２の口頸部３外周に回動を防止して嵌合した装着筒７より口頸部３上端開口を被覆する被覆板８を延設するとともに、被覆板８中央部を下方に円筒状に凹ませた陥没部8bを設け、且つ、容器体に液密に嵌着固定してなる固定部Ｄを備え、また、上記陥没部周壁26内周上部に回動可能に嵌合した摺動筒部28を底壁10a 中央部を貫通して垂設するとともに、上記陥没部8bとともに計量室Ａを画成し、且つ、周縁部下部より延設した回動筒９を固定部Ｄ外周に回動可能に嵌合させたケーシング10と、計量室Ａ上端の上記ノズル筒５に設けた上記棒栓６とで構成した可動部Ｅを備えている。
【００４４】
更に具体的には、固定部Ｄは、その装着筒７を上記図１の実施例と同様の手段で抜け出しを防止して、また、回動を防止して、口頸部３外周に嵌合させており、その上端縁より延設した被覆板８の中央部を円筒状に凹ませて陥没部8bを形成している。更に、被覆板８の上面外周縁部からは上記係合筒13を立設しており、上記固定壁部としての上記陥没部8bの上下方向中間部所定位置に外透孔4aを穿設している。
【００４５】
また、可動部Ｅは、その回動筒９を上記図１の実施例と同様の手段で抜け出しを防止して口頚部１外周に装着している。また、係合筒13外面上端と回動筒９内面上端との間に同様の回動規制機構21を備えており、上記可動壁部としての上記摺動筒部28外透孔対応位置に内透孔4bを穿設している。更に、液導入孔４下方の計量室Ａ内として構成した計量凹部Ｂを設けている。尚、固定部Ｄ及び可動部Ｅはそれぞれ２部材で構成している。
【００４６】
上記の如く構成した液体計量塗布栓１を使用する場合について説明する。図21の状態から容器１を倒立させると、図22に示す如く、計量室Ａ内に容器体２内の液が液導入孔４を介して導入される。次いで、この状態から容器１を正立させると、図23に示す如く、計量室Ａ下端部の計量凹部Ｂ内に液が計量され、残りは液導入孔４を介して容器体２内へ戻される。
【００４７】
次いで、可動部Ｅを所定方向に回動させて液導入孔４を閉塞した後、図24に示す如く、容器体２を倒立して被塗布部分25に対して棒栓６を押し付け計量液の塗布を行う。
【００４８】
上記各実施例に於いて、各部材は合成樹脂により形成すると良い。また、図１，図７，図11，図13，図15の各実施例に於いては、上記可動部Ｅの少なくとも計量室Ａを構成する周壁及び頂壁部分を透明材質で形成すると良い。
【００４９】
【発明の効果】
