Description

【０００１】
【産業上の利用分野】
本発明は、スクイズ性を利用して内容液を注出する合成樹脂製壜容器に関するものである。
【０００２】
【従来の技術】
胴部を把持した指先での押圧により、この胴部をスクイズ変形させてシャンプーやリンス等の内容液を注出する合成樹脂製の液体注出壜容器が知られている。このスクイズ性を有する液体注出容器は、小さな注出口を有するキャップまたは中栓を容器本体の口筒部に組付け、容器本体を略倒立させた状態で、容器本体の胴部を押圧してスクイズ変形させ、この胴部のスクイズ変形により容器本体内に発生する正圧によって、内容液を注出口から整流状態で注出し、注出する内容液の量は、胴部に対する押圧操作に従ったスクイズ変形量により調整されるものとなっている。
【０００３】
【発明が解決しようとする課題】
従来のスクイズ性を利用した液体注出容器は、内容液の注出操作が簡単で、その取扱いが容易であると云う利点を持っているのであるが、胴部に対する指先での押圧程度を一定化させることが困難であるため、一回の注出操作による内容液の注出量が一定せず、注出操作の度に使用する内容液の過不足が発生する場合が多いと云う問題があった。
【０００４】
また、容器が転倒した場合とか、内容液注出後、容器を略倒立させた状態のまま、胴部に対する押圧力を解除した場合には、内容液の漏れ出しが発生すると云う問題があり、特に注出操作後における液切れが悪いと云う問題があった。
【０００５】
一回の注出操作による内容液の注出量を一定化する手段としては、注出ポンプを組付けた容器が利用されているが、この種の容器は、高価な注出ポンプを必要とするので、その分、容器の価格が高くなるだけではなく、携帯が不可能となると云う新たな問題が生じるものとなっていた。
【０００６】
そこで、本発明は、上記した従来技術における問題点を解消すべく創案されたもので、スクイズ変形を利用した内容液の注出において、一回の注出操作による内容液の注出量を定量化させると共に液切れを円滑に達成させることを技術的課題とし、もって内容液の好適な使用状況を得ると共に、容器の快適な使用状態を得ることを目的とする。
【０００７】

【００２４】
請求項１５に記載の発明は、請求項１から１４に記載の発明において、押圧操作部を、容器本体胴部の外面上端からその押圧操作部の中心部分までの長さ距離が、容器本体胴部の高さ距離の２／３である設定距離以内となるべく形成して構成した。
【００２５】

【００２６】

【００２７】
請求項１８に記載の発明は、請求項１から１５に記載の発明において、規制筒体を、その上端部である嵌着筒部とその下位部分である筒体本体部とで構成し、
該筒体本体部に、窓孔に代えて、複数の通孔を形成して構成した。
【００２８】
請求項１９に記載の発明は、請求項１から１８に記載の発明において、規制筒体の下端に、下方に縮径するテーパ筒体を一体連設して構成した。
【００２９】
【作用】
請求項１に記載の発明においては、キャップ体を開放し、かつ容器本体を略倒立させた状態で、容器本体の胴部の押圧操作部を指先で押圧して、この押圧操作部が規制筒体に突き当たるまで容器本体の胴部をスクイズ変形させ、この胴部のスクイズ変形による容器本体内の内圧の正圧化により、弁機能部を開状態にして容器本体内の内容液を注出する。
【００３０】
この内容液の注出動作時において、容器本体の胴部のスクイズ変形は、押圧操作部が規制筒体に突き当たる状態で規制され、かつ規制筒体はスクイズ変形し難いものであるので、容器本体の胴部のスクイズ変形量は、押圧操作部を規制筒体に突き当たるまで押圧することにより略一定値となり、これにより押圧操作部を規制筒体に突き当たるまで押圧する一回の操作による内容液の注出量は、略一定値となり、定量注出動作を得ることができる。
【００３１】
注出操作完了後は、容器本体内の正圧が消滅するので、弁機能部は閉塞状態となって内容液の通過を規制する状態となるので、例え容器本体が倒立状態であっても、内容液の液垂れの発生を未然に防止できる。
【００３２】
また、注出操作完了後は、容器本体内に発生した負圧により、弁機能部に規制されながらも、外気が弁機能部を通過して容器本体内に吸引されて容器本体内の負圧を消滅させて次の注出に備えることができる。
【００３３】
容器が安置された状態では、弁機能部が閉状態となっているので、例え容器本体が転倒しても、内容液が不正に漏出することがなく、容器本体の閉鎖状態を保持することになる。
【００３４】
なお、内容液が少なくなった状態では、容器本体の倒立姿勢で、内容液は規制筒体の窓孔を通って規制筒体内に侵入して弁機能部に到達することができるので、内容液は最後まで注出されることになる。
【００３５】
請求項２から５に記載の発明は、請求項１に記載の発明の弁機能部を、それぞれメッシュ弁構造、細孔構造、スリット弁構造および揺動弁構造で構成したので、円滑で良好な内容液注出動作と外気吸引動作とを得ることができると共に、弁機能部および注出容器を安価に成形することができる。
【００３６】
請求項６に記載の発明は、請求項１から５に記載の発明において、弁機能部をキャップ体と別体成形して構成したので、内容液の粘度によって適切な弁機能部を使用することができる。例えば、細孔構造の弁機能部の場合、容器本体に収納する内容液の粘度が高ければ、細孔の径の大きなものをキャップ体に組み付けることによって対応できるので経済的である。
【００３７】
請求項７に記載の発明は、請求項１から６に記載の発明の押圧操作部を陥没構造としたので、視覚のみならず触感による押圧操作部の位置の認識が容易となり、また押圧操作部と規制筒体との間の間隔を、容器本体の胴部の平断面形状に制限されることなく、所望値に設定することが可能となる。
【００３８】
請求項８に記載の発明は、請求項１から７に記載の発明において、押圧操作部を凹状押圧部と押しプレート片との二重構造としたので、その部分の機械的強度が高まり、よって押しプレート片を押圧するとその周辺部分の容器本体胴部の変形が円滑に達成され、より良い使用感を得ることができる。
【００３９】
請求項９に記載の発明は、請求項１から８に記載の発明において、押圧操作部を波板状に設けたので、触感での位置の確認がさらに容易となる。
【００４０】
請求項１０に記載の発明は、請求項１から９に記載の発明において、押圧操作部を上下に複数組設けたので、内容液注出操作時における容器本体の把持処理の自由度が高くなる。
【００４１】
請求項１１に記載の発明は、請求項１０に記載の発明において、各押圧操作部と規制筒体との間の間隔を異なる値としたので、各押圧操作部別に胴部のスクイズ変形量、すなわち内容液の注出量を異なる一定値に設定することができ、これにより一回の定量注出量を選択することが可能となる。
【００４２】
請求項１２および１３に記載の発明は、請求項１０に記載の発明において、各押圧操作部と規制筒体との間隔を、各押圧操作部の成形深さあるいは規制筒体の太さを異なる値としたので、簡易な構成で一回の定量注出量を選択することができる。
【００４３】
請求項１４に記載の発明は、請求項１から１３に記載の発明において、キャップ体をヒンジキャップ構造としたので、容器本体の開閉取扱いが容易となり、又、キャップ本体に注出口を設けたので、内容液の注出の方向性が良くなると共に、内容液の注出形態が安定する。
【００４４】
請求項１５に記載の発明は、請求項１から１４に記載の発明の構成のうち、押圧操作部を、容器本体胴部の外面上端からその中心部分までの長さ距離が、容器本体胴部の高さ距離の２／３である設定距離以内となるべく形成したので、押圧操作部を指先で押圧して内溶液を注出する際に、容器本体を安定姿勢に維持することができる。
【００４５】
請求項１６に記載の発明は、請求項１から１５に記載の発明において、規制筒体の窓孔を、その上端が容器本体胴部の内面上端より上位に位置すべく形成したので、内容液が残り少なくなっても当該窓孔からスムースに注出することができ、よって内容液の残量を極力少なくすることができる。
【００４６】
請求項１７に記載の発明は、請求項１から１６に記載の発明において、規制筒体の筒体本体部にガイド溝を形成したので、内容液をスムースに窓孔に導くことができ、内容液の注出操作をより円滑に行うことができる。
【００４７】
請求項１８に記載の発明は、請求項１から１５に記載の発明において、規制筒体を、その上端部である嵌着筒部（６）とその下位部分である筒体本体部（２５）とで構成し、該筒体本体部（２５）に、窓孔に代えて、複数の通孔を形成して構成したので、内容液をその複数の通孔からスムースに弁機能部に案内することができる。
【００４８】
請求項１９に記載の発明は、請求項１から１８に記載の発明において、規制筒体の下端に、下方に縮径するテーパ筒体を垂下連設したので、その規制筒体とテーパ筒体との一体物の下端の外径は、容器本体口筒部の内径よりも大幅に小さくなり、よって当該一体物を、容器本体内へ容易に挿入組付けすることができる。
【００４９】
【実施例】
本発明の一実施例を、図１から図３に示す。
容器本体１は、ポリエチレン樹脂や塩化ビニール樹脂等の比較的軟質な合成樹脂材料により壜体状にブロー成形され、スクイズ変形可能な有底筒形状となった胴部２の上端に、外周面に螺条を刻設した口筒部４を起立連設して構成されている。容器本体胴部２の中央部から上部にかけての把持し易い箇所に、押圧操作部３を対向して一対形成している。
【００５０】
規制筒体５は、その上端部を口筒部４内に嵌入固着させる嵌着筒部６としており、又、嵌着筒部６の上端縁に、口筒部４の上端面に搭載して、規制筒体５の容器本体１内への挿入組付け限を設定する外鍔片３１を周設している。この規制筒体５の嵌着筒部６の下位部分である筒体本体部２５は、その上端部に内容液が通過する窓孔９を有すると共に、その下位に当該窓孔９に内容液を案内する四つのガイド溝２６を有している。このガイド溝２６は、筒体本体部２５の周壁を複数箇所で陥没成形することによって縦方向に形成されている（図３参照）。
【００５１】
キャップ体１０は、キャップ本体１９とそれにヒンジ２１によって結合された蓋板体２０とから構成される。キャップ本体１９は、その外筒部１１が容器本体１の口筒部４に密に外装組付きすると共に、その内筒部１２が規制筒体５の嵌着筒部６に密に内装組付きすることによって、容器本体１に強固に組付けられている。内筒部１２の内側には内容液の注出口１３を形成する注出筒部２８が設けられ、又、この注出口１３の中心部には、注出筒部２８と一体設された中央片３５が起立設されている。この注出筒部２８と中央片３５との間には、内容液が通過する複数の通過部１４が開口されている。蓋板体２０は，その下面からキャップ本体１９の注出筒部２８に密に嵌入する円筒状の栓片２２を垂下設している。
【００５２】
本実施例における弁機能部７は、キャップ体１０とは別体成形された有底円筒形状で、その底壁にメッシュ１６が形成されたメッシュ構造で、当該底壁および周壁が中央片３５および注出筒部２８にそれぞれ外装組付けされて、キャップ体１０に取付けられている。
【００５３】
本実施例にあっては、キャップ体１０を開放し、容器本体１を略倒立させた状態で、押圧操作部３を規制筒体５に突き当たるまで押圧することにより、内容液の定量注出を達成する。
【００５４】
すなわち、押圧操作部３を押圧することによって、容器本体１の胴部２がスクイズ変形し、これにより容器本体１内に発生した正圧により一定量の内容液が窓孔９、メッシュ１６、通過部１４、および注出口１３を通って注出される。
【００５５】
内容液注出後、押圧操作部３の押圧を停止すると共に容器本体１を正立姿勢に戻すと、外気がメッシュ１６の間を通って容器本体１内に吸引されて胴部２が原形に復帰し，次の注出操作に対応できる状態となる。
【００５６】
なお、本実施例に係る液体注出容器の規制筒体５の下端には、下方に縮径するテーパ筒体２７が一体的に垂下連設されており、こうした構成とすることによって、規制筒体５とテーパ筒体２７との一体物の下端の外径を容器本体口筒部４の内径より大幅に小さくし、当該一体物の容器本体１内への挿入を容易なものとしている。
【００５７】
又、本実施例においては、押圧操作部３を、容器本体胴部２の外面上端２３からその中心部分までの長さ距離Ｌが、容器本体胴部２の高さ距離Ｈの２／３である設定距離Ｄ以内となるべく形成されている。従って、押圧操作部３を指先で押圧して内容液を注出する際に、容器本体１を安定姿勢に維持することができる。ちなみに、長さ距離Ｌが設定距離Ｄ以内でないと（すなわち、押圧操作部３を容器本体胴部２の下端部分に形成すると）、押圧操作部３を押圧した場合、容器本体１の姿勢が不安定なものとなり、内容液の注出を円滑に行うことが困難となる。
【００５８】
又、本実施例おいては、規制筒体５の窓孔９を、その上端が容器本体胴部２の内面上端２４より上位に位置すべく形成している。従って、内容液が残り少なくなった場合でも、その窓孔９からスムースに注出され、内容液の残量を極力少なくすることができる。
【００５９】
なお、本実施例における規制筒体５は、窓孔９およびガイド溝２６を有するものであるが、これに代えて、図４に示すように、筒体本体部２５に複数の通孔３３を穿設したものであっても良い。この場合、容器本体１内の内容液は、筒体本体部２５下端の開口部およびこの通孔３３を通って弁機能部７に達する。
【００６０】
なお、メッシュ構造の弁機能部７は、キャップ本体１９の注出筒部２８の下端部に、当該キャップ本体１９とメッシュ１６とを一体成形して構成することもできる。
【００６１】
本発明の他の実施例を、図５および図６に示す。
これらは共に、弁機能部７を細孔構造としたものである。図５に示すものは、キャップ本体１９の注出筒部２８の下端部に複数の細孔８を有する板片を一体成形して構成したものであり、図６に示すものは、有底円筒形状の底壁に複数の細孔８を穿設し、その周壁をキャップ本体１９の注出筒部２８に嵌合組付けしたものである。
【００６２】
本発明のさらに他の実施例を、図７から図９に示す。
本実施例における特徴は、その弁機能部７を、軟質材料製でその中心部にスリット１５を形成した冠形状の弁体部２９と、当該弁体部２９の周端部から起立周設され、キャップ本体１９の注出筒部２８に外装組付きする組付き筒部３０とから成るスリット弁構造で構成していることである（図９参照）。このスリット１５は通常、閉状態にあり、押圧操作部３を押圧して容器本体１内が正圧になると、その圧力によって開口され内溶液の通過を許すものである。
【００６３】
本発明のさらに他の実施例を、図１０および図１１に示す。
本実施例における弁機能部７は軟質合成樹脂材で成形され、平面円形状のその中心部である固定部３４が容器本体１の注出筒部２８に一体成形された中央片３５に嵌入組付きし、その中央片３５から周設され弾性変形自在な揺動片３２とで成る、いわゆる揺動弁構造で構成されている。揺動片３２の外周端はキャップ本体１９の内筒部１２に周設されたシール突条部３６に弾接して内容液の通過を阻止し、容器本体１内に正圧が生じた際に、その圧力によって上方に弾性変形して内筒部１２との間に内容液が通過する開口部を形成するものである。内容液はその開口部、注出筒部２８と中央片との間に形成された複数の通過部１４、および注出口１３を通って注出される。容器本体１内の正圧が消滅すると、揺動片３２は弾性復帰力によって原形に復帰し、閉状態を形成する。
【００６４】
図１２および図１３は、同じく弁機能部７を揺動弁構造で構成したものである。この弁機能部７は、有底筒形状の底壁中央部を開口したもので、周壁がキャップ本体の内筒部１２に嵌入組付きすると共に、底壁である揺動片３２の内周端が注出筒部２８に一体成形された中央片３５の外周面に密に接触して閉状態を形成する。容器本体１内に正圧が生じるとその圧力によって揺動片３２が上方に弾性変形して中央片３５との間に開口部を形成し、内容液の注出を可能にするものである。
【００６５】
本発明の押圧操作部３部分に関し，他の実施例を図１４から図１７にそれぞれ示す。
図１４に示す実施例は，押圧操作部３を上下に二対形成し、上位のものの陥没成形深さを下位のものより大きく設定したものである。従って、上位の押圧操作部３に比べて下位の押圧操作部３の湾曲陥没程度が小さいので、規制筒体５との間の間隔は、上位の押圧操作部３に比べて下位の押圧操作部３の方が大きく、それゆえ規制筒体５に突き当たるまで押圧操作した場合に、上位の押圧操作部３に比べて下位の押圧操作部３の方が大きい定量注出となる。
【００６６】
図１５に示す実施例は，上記実施例と同様に上位の押圧操作部３の陥没深さを下位のものより大きく設定すると共に、規制筒体５の、上位の押圧操作部３に対向する部分の外径を下位に対向する部分より大きく設定したものである。従って、下位の押圧操作部３における定量注出量は、上位のそれより、さらに大きくなる。
【００６７】
図１６に示す実施例は、その押圧操作部３を規制筒体５を挟んで対向する箇所に、容器本体胴部２に形成した凹状押圧部１７と、その凹状押圧部１７に組付く押しプレート片１８とで構成したものである。これにより、押圧操作部３の機械的強度がその周辺部分より高くなり、よって当該押圧操作部３を押圧することによる胴部２のスクイズ変形が容易に達成され、注出操作がし易くなる。
【００６８】
図１７に示す実施例は，押圧操作部３を、規制筒体５を挟んで対向する箇所に波板状に設けたものである。こうした構成とすることによって、指先での感触のみで容易に押圧操作部３の位置を確認することができると共に、指先での押圧操作の滑りを少なくし、内容液を円滑に注出することができる。
【００６９】
【発明の効果】
本発明は、上記した構成としたので、以下に示す効果を奏する。
請求項１に記載の発明は、内容液を注出するための胴部のスクイズ変形量の上限が、規制筒体により略一定に規制されるので、一回の注出操作による内容液の注出量を略一定量に設定することができ、もって従来通りの簡単な押圧操作によって内容液の定量注出効果を確実に得ることができ、内容液を適正に無駄なく使用することができる。
