Description
本願は、2013年10月2日に日本に出願された特願2013-207607号に基づき優先権を主張し、その内容をここに援用する。
また、この種の容器本体には、内容物の注出量を調整したり、詰め替えパウチからの内容物を補充するためのノズル中栓を嵌合した形態が多く用いられているが、内容物が液体の場合、ノズル中栓と計量キャップの着脱構造は、輸送やハンドリングにおいて液漏れを生じ難いようにネジ嵌合構造とされることが一般的である。
また、液体を収容物とする中空容器の口頸部に注出筒を有する注出中栓を装着するとともに、この注出中栓に螺合される底深の計量キャップ兼用の蓋体を備えた計量器付き容器が以下の特許文献2に記載されている。
図12に示す計量キャップ103においては、計量筒部100の周壁に計量目盛り105を形成しているので、計量筒部100に収容した内容物の容量を把握することができる。
また、ねじ部106を利用して計量キャップ103を容器本体の口頸部にネジ込みにより嵌合する構造では、洗浄剤を取り扱う際に手指が水分で汚れていたり、洗浄剤が付着していると、手指が滑りやすくなり、ねじ込み固定した計量キャップ103を容器本体の口頸部から取り外し難いケースがあるとともに、操作し難い問題があった。
本実施態様は、口頸部を有し、液状または粉状の内容物を収容可能な容器本体と、前記口頸部に装着されたノズル中栓と、このノズル中栓に着脱自在に設けられた計量キャップを備えた計量容器であって、前記ノズル中栓は、前記口頸部に装着される筒壁部を有し、この筒壁部の内側に注出口が形成されており、前記計量キャップは、前記ノズル中栓の筒壁部に一部挿入される計量筒部と、この計量筒部の一側開口端を閉じる蓋部と、前記計量筒部の周面から外方に張り出し、前記ノズル中栓の筒壁部上端の開口部に被せられるフランジ部と、このフランジ部の縁部から垂下され、前記計量キャップの装着時に前記筒壁部の外面に沿わせられる延出片を備え、前記延出片は、下端に向かって幅が狭くなっており、前記計量キャップは前記ノズル中栓に装着した状態で周方向の少なくとも一方に回動でき、前記筒壁部の外面には、前記計量キャップを装着して周方向に回動させた時に前記延出片の下端部が当接する段差壁部が形成され、前記段差壁部が前記筒壁部の上方に向かって延び、かつ周方向に傾斜している計量容器に関する。
また、前記筒壁部の外面と前記延出片の内面に、前記計量キャップの周方向への回動を案内する第2の係合部が形成され、前記筒壁部の外面および前記延出片の内面の双方もしくはいずれか一方には前記第2の係合部の端縁部から前記段差壁部に沿った延長係合部が形成されていることが好ましい。
また、前記延出片に弾性が付与されていることが好ましい。
また、前記延出片が前記フランジ部の周方向対称位置に2つ以上形成されていることが好ましい。
以下、本発明の第1実施形態について図面を参照しつつ詳細に説明する。
計量容器Cは、図1および図2に示すように、口頸部2を有する樹脂製の中空の容器本体1と、容器本体1の口頸部2に装着されたノズル中栓203と、ノズル中栓203に着脱自在に設けられた計量キャップ205を備えている。
この例では、容器本体1の口頸部2とノズル中栓203はいずれも概略円筒形状をなしており、ノズル中栓203を容器本体1の口頸部2に装着した状態においてそれらの中心軸線(図2(b)の中心軸線C1)は一致している。
口頸部2は、図2(b)に示すように円筒状に形成され、その外周部にねじ部2aが形成されている。
内筒壁13は外筒壁11の下端より若干下方まで達するように外筒壁11と平行に延出されている。内筒壁13の下端には傾斜面16aを有する底壁部16が設けられており、底壁部16には注出口16bが遍在して形成されている。底壁部16における注出口16bの周縁部には注出筒17が立設されている。
また、ノズル中栓203には、外筒壁11と内筒壁13との間の接続壁12の下面から垂下された筒状のシールリップ部15が形成されている。これにより、ノズル中栓203を容器本体1の口頸部2に螺合により装着した状態において、シールリップ部15が口頸部2の開口部に密に挿入されることで、口頸部2の開口部が液密に閉塞される。
段差壁部11Cは、図3(a)に示すように、正面視した場合にサインカーブの一部を切り取ったような形状とされており、その底部の両側において筒壁部10の上方に向かって延び、かつ周方向に傾斜している。
この例の窪部11Aでは、段差壁部11Cの底部が外筒壁11の下端近くに位置し、窪部11Aの上端部の周方向の幅が外筒壁11の全周の1/6程度となっている。
また、フランジ部23の内周縁部には、下方に突出するリング部24が形成されている。
計量筒部22の周壁における2つの延出片25の間の部分には、図4(c)に示すように、計量用の目盛線と容量表示用の数字を備えた目盛部32が印刷、刻印等の手段により形成されている。これにより、計量キャップ205を倒立させた状態で、計量筒部22の開口部22aから注入された液体等の内容物の量を把握することができる。
フランジ部23は、計量キャップ205がノズル中栓203に装着される際に、ノズル中栓203の筒壁部10上端の開口部に被せられる。
延出片25は、フランジ部23の周回りに180゜間隔で、すなわちフランジ部23の周方向対称位置に2つ形成されている。2つの延出片25は、計量キャップ205の装着時に、ノズル中栓203の筒壁部10の外面における2つの窪部11Aにそれぞれ沿わせられる。
なお、本実施形態の変更態様として、延出片の下端部を段差壁部の底部に位置合わせした時に該延出片の下端部が段差壁部に当接するようにしてもよい。
容器本体1の製造方法としては、例えばポリエチレン等のオレフィン系合成樹脂を用いたブロー成型等により一体として成型する方法が挙げられる。ノズル中栓203の製造方法としては、例えばポリプロピレン等のオレフィン系合成樹脂を用いた射出成型により一体として成型する方法が挙げられる。計量キャップ205の製造方法としては、例えばポリエチレン等のオレフィン系合成樹脂を用いた射出成型により一体として成型する方法が挙げられる。
容器本体1、ノズル中栓203、計量キャップ205の製造方法は、前記した方法には限定されない。
以下、計量容器Cにおけるノズル中栓203と計量キャップ205の取り付け操作、取り外し操作、および計量操作について説明する。
計量容器Cでは、容器本体1内に内容物が収容された状態で、図2(b)に示すように、注出筒17を上向きとしてノズル中栓203の内筒壁13が口頸部2の内側に挿入され、外筒壁11のねじ部11aが容器本体1の口頸部2のねじ部2aに螺合されて、ノズル中栓203が容器本体1の口頸部2に装着されている。容器本体1の口頸部2の開口部は、ノズル中栓203のシールリップ部15によって液密に閉塞されるため、口頸部2のねじ部2aとノズル中栓203のねじ部11aの螺合部分を介する液漏れが防止されている。
また、図2(a)に示すように、ノズル中栓203に計量キャップ205が装着された状態においては、計量キャップ205の2つの延出片25がノズル中栓203の筒壁部10の2つの窪部11Aにそれぞれ位置し、2つの延出片25によってノズル中栓203の筒壁部10が挟み込まれるようになっている。
計量容器Cでは、計量キャップ205を周方向に右回りに回動させても、同様に計量キャップ205を取り外すことができる。
本実施形態の計量キャップ205では、目盛部32の周囲に存在するのは、フランジ部23の周方向対称位置に設けられた2つの延出片25,25のみである。そのため、延出片25,25の間から目盛部32が視認しやすく、計量筒部22に収容した内容物の量を正確に把握することができる。
計量を終えて内容物を使用した後は、図6に示すように、計量キャップ205の延出片25の位置をノズル中栓203における外筒壁11の窪部11Aの位置に合わせつつ、計量筒部22をノズル中栓203の筒壁部10に挿入して装着する。
以上のように、計量容器Cでは、従来のねじ込み式の計量キャップに比べて計量キャップ205の取り付け操作および取り外し操作が遙かに簡便に行えるため、手指が洗剤等で汚れていて滑りやすい状態であっても支障なく取り付けおよび取り外しができる利点を有する。
本実施形態の計量容器では、ノズル中栓の筒壁部の外面と計量キャップの延出片の内面に、ノズル中栓に対する計量キャップの相対的な上方移動を規制する第1の係合部が形成されていることが好ましい。また、筒壁部の外面と延出片の内面に、計量キャップの周方向への回動を案内する第2の係合部が形成され、前記筒壁部の外面および前記延出片の内面の双方もしくはいずれか一方には前記第2の係合部の端縁部から段差壁部に沿った延長係合部が形成されていることが好ましい。
以下、これらの構成を採用した実施形態の一例について説明する。
第1の案内凸部18は、窪部11Aにおける幅方向のほぼ中央部分であって外筒壁11の上端部近くに形成された、周方向に延びる凸条からなる。第1の案内凸部18は、外筒壁11の周方向において、平面視における中心軸線C1を中心とする15~20°の範囲内に形成されている。
この例の第1の案内凸部18は、正面視で周方向における段差壁部11Cの底部に対応する位置から左端までの長さが、当該位置から右端までの長さよりも長くなっている。この場合、装着した計量キャップ5を左回りに回動させたときには、後述の第3の案内凸部27の係合が外れやすく、計量キャップ5を右回りに回動させたときには第3の案内凸部27の係合が外れ難くなる。これにより、計量キャップ5を取り外す際の計量キャップ5の回動方向を規制することができる。
なお、第1の案内凸部18は、正面視で周方向における段差壁部11Cの底部に対応する位置から左端までの長さと、当該位置から右端までの長さを等しくして、周方向の両方向への回動しやすさが同じになるようにしてもよい。
延長凸部20は、図8(a)に示すように、第2の案内凸部19を正面視した場合の右端縁部から第2の案内凸部19を延長するように段差壁部11Cに沿って斜め上方に傾斜して延びている。延長凸部20の第2の案内凸部19側の始端部20aは円弧状に形成され、第2の案内凸部19と滑らかに接続されている。延長凸部20の主体部20bは直線状にかつ周方向に対する所定の傾斜角(例えば40~70゜)で斜め上方に向かうように形成されている。
第2の案内凸部19と延長凸部20とは、段差壁部11Cから離間し、第2の案内凸部19と延長凸部20の正面視形状が段差壁部11Cの正面視形状と相似形状となっている。
ノズル中栓3および計量キャップ5の製造方法は、特に限定されず、例えばノズル中栓203および計量キャップ205で挙げた方法と同じ方法が挙げられる。
以下、計量容器Aにおけるノズル中栓3と計量キャップ5の取り付け操作、取り外し操作、計量操作について説明する。
ノズル中栓3の容器本体1の口頸部2への装着は、計量容器Cにおけるノズル中栓203の装着と同様になっている。
図7(a)に示すように、ノズル中栓3に計量キャップ5を嵌合した状態においては、ノズル中栓3の第1の案内凸部18の下側に延出片25の第3の案内凸部27が係合し、ノズル中栓3の第2の案内凸部19上に延出片25の第4の案内凸部28が隣接係合している。この状態では、第1の案内凸部18と第3の案内凸部27の係合により、ノズル中栓3に対する計量キャップ5の相対的な上方移動が規制されるため、計量キャップ5が抜け止めされている。
計量が終了して計量キャップ5を再びノズル中栓3に装着する際は、図11の矢印bに示すように計量キャップ5の計量筒部22をノズル中栓3の内筒壁13の内側に挿入するとともに、延出片25をノズル中栓3の窪部11Aの位置に合わせて計量キャップ5をノズル中栓3に押し込むことで装着することができる。
計量キャップ5の延出片25が適度な弾性を有すれば、図11に示すように計量キャップ5の左右両側の延出片25,25でノズル中栓3の外筒壁11を挟みつつ下降させることで、第1の係合部29において第3の案内凸部27が第1の案内凸部18を容易に乗り越える。これにより、容易に第3の案内凸部27を第1の案内凸部18で抜け止めした状態にできる。
また、計量容器Aは第1の係合部29を有するため、計量容器Cに比べて計量キャップ5を装着した状態をより安定して維持できる。更に、第1の係合部29、第2の係合部30および延長係合部31を有することで、装着した計量キャップ5を周方向に回動させた際にそれら係合部の案内によって計量キャップ5がよりせり上がりやすいため、計量キャップ5の取り外しが更に容易である。
計量容器Aでは、ノズル中栓3の外筒壁11に第1の案内凸部18と第2の案内凸部19と延長凸部20を設け、計量キャップ5の延出片25に第3の案内凸部27と第4の案内凸部28を設けたが、これらを凹部と凸部による嵌合構造としても良い。
凹部と凸部による嵌合構造の一例として、図13と図14を基に以下に説明する嵌合構造を採用することができる。
第3実施形態の計量容器Bは、計量容器Aのノズル中栓3と一部を除いて同一構造のノズル中栓3Aと、計量容器Aの計量キャップ5と一部を除いて同一構造の計量キャップ5Aを備えている以外は、計量容器Aと同じである。
ノズル中栓3Aにおいて、計量容器Aのノズル中栓3と異なっているのは、窪部11Aに形成されていた第1の案内凸部18の代わりに第1の案内凹部18Aが形成され、第2の案内凸部19の代わりに第2の案内凹部19Aが形成されている点である。また、計量容器Aにおいて形成されていた延長凸部20の代わりに延長凹部20Aが形成されている点が異なる。
また、計量キャップ5において延出片25の内面には、計量容器Aの第3の案内凸部27と同一形状の第3の案内凸部27Aが形成され、第4の案内凸部28と同一形状の第4の案内凸部28Aが形成されている。
計量容器Bでは、第3の案内凸部27Aは計量キャップ5Aをノズル中栓3Aに装着し嵌合した状態において第1の案内凹部18Aに嵌合し、第4の案内凸部28Aは同状態において第2の案内凹部19Aに嵌合するようになっている。
また、ノズル中栓3Aの第2の案内凹部19Aと計量キャップ5Aの第4の案内凸部28Aにより第2の係合部40が形成される。計量キャップ5Aをノズル中栓3Aに装着した状態において、ノズル中栓3Aの外筒壁11に形成された第2の案内凹部19Aに、計量キャップ5Aの延出片25に形成された第4の案内凸部28Aが嵌合する。更に、ノズル中栓3Aの延長凹部20Aと計量キャップ5Aの第4の案内凸部28Aにより延長係合部41が形成される。計量キャップ5Aを周方向に回動させて取り外す際、ノズル中栓3Aの外筒壁11に形成された延長凹部20A内を、計量キャップ5Aの延出片25に形成された第4の案内凸部28Aが移動する。
具体的には、計量キャップ5Aを左回りに回動させると、第3の案内凸部27Aが第1の案内凹部18A内を摺動するとともに、第4の案内凸部28Aが第2の案内凹部19A内を摺動し、延出片25の下端部25aが段差壁部11Cに当接する。計量キャップ5を更に回動させると、第3の案内凸部27Aが第1の案内凹部18Aから外れ、延出片25の下端部25aが段差壁部11Cを摺動し、第4の案内凸部28Aが延長凹部20A内を摺動することで、延出片25を斜め上方に移動させる力が作用する。これにより、計量キャップ5Aは回動しつつ斜め上方に移動するため、計量キャップ5Aを容易に取り外すことができる。
また、計量容器Bは、計量容器Aと同様に、第1の係合部39を有するために計量キャップ5Aを装着した状態をより安定して維持できる。更に、第1の係合部39、第2の係合部40および延長係合部41を有することで、計量キャップ5Aの取り外しが容易である。
なお、本実施形態の変更態様として、計量容器は、前記した計量容器A~Cには限定されない。
例えば、計量キャップの延出片の一方の側縁部の周方向に対する傾斜角度と、該計量キャップの装着時に前記一方の側縁部に対向するノズル中栓の段差壁部の周方向に対する傾斜角度が80°以上とされ、該計量キャップを装着した状態で延出片の前記一方の側縁部とそれに対向するノズル中栓の段差壁部とが接している計量容器であってもよい。該計量容器では、計量キャップを周方向の前記一方の側縁部側には回動することができず、計量キャップの周方向の回動方向が一方向に制限される。
具体例としては、図15に例示した計量キャップ5Bとノズル中栓3Bを有する計量容器が挙げられる。計量キャップ5Bは、延出片25Aの正面視左側の側縁部の周方向に対する傾斜角度φが90°となっている以外は計量キャップ205と同じである。ノズル中栓3Bは、段差壁部11Cにおける底部の正面視左側部分の周方向に対する傾斜角度が90°となっている段差壁部11Dが形成されている以外はノズル中栓203と同じである。計量キャップ5Bをノズル中栓3Bに装着した状態において、延出片25の正面視左側の側縁部は、段差壁部11Dにおける底部の正面視左側部分と接している。装着した計量キャップ5Bは、周方向に右回りには回動できず、周方向の回動方向が左回りに制限されている。装着した計量キャップ5Bを取り外す際には、計量キャップ5Bを周方向に左回りに回動させることで、計量容器Cと同様に取り外しできる。
具体例としては、図16に例示した計量キャップ5Cとノズル中栓3Cを有する計量容器が挙げられる。ノズル中栓3Cは、段差壁部11Cの周方向に対する傾斜角度ψが例えば5~15°と小さく設定されている以外は、ノズル中栓203と同じである。計量キャップ5Cは、ノズル中栓3Cに装着した際に延出片25Bの下端部25aよりも上方の両方の側縁部が段差壁部11Cと接している以外は計量キャップ205と同じである。
図16に例示した計量容器では、ノズル中栓3Cの段差壁部11Cの周方向に対する傾斜角度が小さく設定されているため、装着された計量キャップ5Cを周方向に回動させることで計量容器Cの場合と同様に延出片25Bが段差壁部11Cを摺動して上方にせり上がる。そのため、計量キャップ5Cを容易に取り外すことができる。
具体例としては、図17に例示したノズル中栓3Dが挙げられる。ノズル中栓3Dは、第2の案内凸部19の左端縁部から延長される延長凸部20Bが形成され、かつ正面視で周方向における段差壁部11Cの底部に対応する位置から左端までの長さと、当該位置から右端までの長さが等しい第1の案内凸部18Bが形成されている以外はノズル中栓3と同じである。
延長凸部20Bは、延長凸部20と同様に、正面視左側の段差壁部11Cに沿って斜め上方に傾斜して延びている。このノズル中栓3Dを用いる場合、装着した計量キャップを左回りに回動させても、右回りに回動させても同様に容易に計量キャップを取り外すことができる。
計量キャップに3つ以上の延出片を設けた場合、ノズル中栓の外筒部に設ける窪部も対応する数だけ設ける構造とすることができる。
更に、上述の構造の変形例として、ノズル中栓3の外筒壁11に案内凸部と案内凹部と延長凹部を設け、計量キャップ5の延出片25に案内凹部と案内凸部を設けてこれらを嵌合して着脱できる構造としても良い。
案内凸部と案内凹部は上述のようにノズル中栓の外筒壁と計量キャップの延出片のどちらに設けても良く、また、案内凸部と案内凹部を2組以上設ける等、適宜変更が可能である。要は、ノズル中栓の外筒壁と計量キャップの延出片に形成する案内凹部あるいは案内凸部であって、計量キャップの延出片の回動操作を上述の場合と同様に制御できる案内凹部と案内凸部の組み合わせであれば、いずれの組み合わせでも実現することができる。
計量キャップ5Dは、延出片25の内面に、第4の案内凸部28の代わりに、計量キャップ5Dの装着時に外筒壁11の第2の案内凸部19の下側に係合する第4の案内凸部28Aが形成されている以外は、計量容器Aの計量キャップ5と同じである。
さらに計量キャップ5Dを周回りに更に回動させると、延出片25の下端部25aが段差壁部11Cを摺動することで延出片25を斜め上方に移動させる力が作用すると同時に、第4の案内凸部28Aが延長凸部20の下面を摺動する。これにより、延出片25の下端部25aが段差壁部11Cを安定して摺動するように案内される。
このように、計量キャップ5Dでは、第2の案内凸部19と第4の案内凸部28Aとの係合による案内によって、計量容器Aに比べて計量キャップ5Dがより安定してせり上がりやすいため、計量キャップ5Dの取り外しが更に容易である。
