Description

【０００１】
【発明の属する技術分野】
本発明は、スクイズボトルの水薬や口内洗浄液等の薬品，化粧品更には洗剤，洗濯用の柔軟剤等の液体を計量して定量排出するのに用いられる定量排出容器に関するものである。
【０００２】
【従来の技術】
従来、この種の定量排出容器は、一般に図７に示されるように、所謂オーバーフロー型定量排出容器として市販されている。この容器の具体構造は、容器本体０１の口部０２に上部に注ぎ口０３を備えた、栓を兼ねる、筒状の計量カップ０４が装着されるとともに、この計量カップ０４の底部０５にはこの底部０５から上方に延びる上部注出パイプ０６が設けられ、この上部注出パイプ０６の下部には容器本体０１の底に延びる下部注出パイプ０７の上端が嵌入されている。そして、前記計量カップ０４は透明な樹脂で構成されていて、その周面には計量目盛０８が設けられている。また、前記上部注出パイプ０６の上端の開口０６Ａは最大計量目盛０８Ａと同一レベルに位置設定されて設けられている。
【０００３】
従って、このようなオーバーフロー型定量排出容器から所定量の液体を注出するには、まず、容器本体０１の胴部０９を手で押圧して、内容液０Ａを下部注出パイプ０７から上部注出パイプ０６を介して計量カップ０４内にオーバーフローさせる。但し、この時、特に重要なのは、この計量カップ０４内に注出される液体の液面が所要の計量目盛０８に正しく一致しているか否かを、目視によって、注意深く確認する必要がある。次いで、液面と計量目盛０８とが一致した時点で、容器本体０１の押圧力を解除すれば、注出パイプ０６内の液体は容器本体０１内に吸い込まれる。この結果、計量カップ０４内には、所定量の液体が注出される。このようにして計量された液体０Ｂは、容器本体０１を傾けることにより、計量カップ０４の注ぎ口０３から注ぎ出される。
【０００４】
また、定量排出手段としては、上記の目視による手段以外に、図示しないが、計量カップを容器本体に対して上下位置変更自在とすることによって、計量カップの底面と上部注出パイプの上端開口との相対的な上下位置を変更することで、この上端開口から計量カップの底面までの距離を可変にし、もって定量の液体を注出させるものが提案されている（一例として、実公平２−２４７６８号公報参照）。
【０００５】
更に、別の手段としては、図示しないが、容器本体の注出口への取付部上に配設された計量カップと、この計量カップの底部を貫通して容器本体底部に達する注出管とで計量機構が構成され、計量カップは、有底筒状でその外周にネジ部が形成され、また、注出管は下端が開放されるとともに、上端が閉塞され、且つこの上端が計量カップのネジ部に外嵌螺合された取付筒体の上端にアームを介して固定されて、この取付筒体の回転による上下動に伴って上下動自在となるように形成され、更に前記注出管の上端近傍の周面には排出孔が設けられ、この排出孔が計量カップ内に配設され、前記取付筒体の回転による上下動に伴ってこの排出孔から計量カップの底部迄の距離を大小変化させることによって、計量カップ内に所望の液体を注出させる手段が提案されている（例えば、実公昭６３−３５９７３号公報参照）。
【０００６】
【発明が解決しようとする課題】
ところが、このような従来の定量排出容器の内、前記第１番目に提示した手段は、基本的には計量カップの計量容積が一定量に定められているため、この定められた一定量の計量しかできないものであるが、計量目盛を設けることで何とか使用の便に供しようとするが、現実には思惑通りの使い勝手は得られにくい。
つまり、このものは、欲しい量の計量目盛とオーバーフローする液体の液面とが正しく一致しているか否かを、目視によって、注意深く確認する必要があるから、計量が大変面倒であり、また、まかり間違えて、欲しい量を越えて内容液をオーバーフローさせてしまうと、その余分な液体を再び容器本体には戻せないから、余分な液体は廃棄するしかなく、無駄が生じる。
【０００７】
また、第２番目に示した、従来の手段では、計量カップ全体を上部注出パイプに対して上下動させる必要があるから、操作に手間がかかるうえに、特に、計量カップを上まで上げたときには、注出パイプでしかこの計量カップの重量を支える手段がないため、計量カップの支えが不安定になり、更には、この上部注出パイプは容器本体の蓋を貫いて上方に突設されていて、この蓋よりも上方に突出した上部注出パイプのねじに計量カップの底部に設けられたねじが螺合されているために、液密なねじ嵌合とは言え、計量カップの支持構造が不安定であるから、このねじ部からの液体が漏れやすく、また、一度漏れた液体は容器外に溢れ、容器や周辺を汚損する結果となる。
【０００８】
そして、第３番目に示した、従来の手段では、注出管は計量カップの底部を貫通して容器本体の底まで延びるものであるが、この注出管と計量カップの底との気密性保持に当たっては、注出管と計量カップの底とを合成樹脂の可撓性を有する材料で形成する必要があるから、他の部分、例えば取付筒体、注出管を取付筒体に結合させるアーム、計量カップの周側壁、ヒンジキャップ、計量カップを容器本体の注出口に螺合させる取付部等、そして特にこの注出管と一体成形される取付筒体、アームそして取付部との材料の整合性が大変困難で、合成樹脂による製造の大きなメリットの一つである、一体成形が適わない問題点がある。更に、注出管の上端を閉塞したり、そのやゝ下方の周側壁に排出孔を形成したり、また、注出管の上端をアームを介して取付筒体に取付ける等、製造しにくい構造となっている。
【０００９】
そこで本発明は、以上のような従来の定量排出容器の問題点を種々検討した結果、この種定量排出容器では、その計量容量が一定の量に決められているものは、まず需要者の便には十分に供しえず、従って、計量容量が可変であることが必須の要件であることを知見し、鋭意検討を重ねて、本発明を開発するに至ったものである。
従って、本発明の第１の目的は、計量容量を可変に出来ながらも、所望量の計量が目視を必要とせずに簡便に行え、また、計量カップから液体が漏れるおそれのない定量排出容器を提供する点にある。
【００１０】
また、本発明の第２の目的は、前記の目的をうまく達成しながらも、更に加えて、計量のための構造が簡素であり、製造も容易である上に、計量容量の変更操作がしごく簡便に行え、付加価値の高い定量排出容器を提供する点にある。
【００１１】
更に、本発明の第３の目的は、計量容量の変更操作を一段と簡便に行え、付加価値の高い定量排出容器を提供する点にある。
【００１２】
そして、本発明の第４の目的は、計量カップの構造を更に簡素にして、経済的に提供できるようにすることである。
【００１３】
【課題を解決するための手段】
上記第１の目的を達成するために、本発明に係る定量排出容器は、次のような手段を講じている。
すなわち、第１の発明は、請求項１に記載されているように、容器本体の注出口にねじ部を介して気密に嵌着される取付け部とその上蓋を底として栓を兼用した有底の計量カップと、この計量カップの前記底を貫通して、上端が計量カップ内の上方に向かって延設され、上端部に注出孔が開口された上部注出パイプと、下端が容器本体内と連通されて前記上部注出パイプに連結された下部注出パイプとから構成されていて、前記計量カップは、前記栓の取付け部に上方に向って立ち上げられた円筒側枠と、この円筒側枠に対して相対回転のみ自在に内嵌合され、上端には回転操作部が設けられた回転内筒とを備え、かつ、前記上部注出パイプはこの回転内筒の中央に設けられたネジ部に螺合されるネジ部を周面に備えると共に、下部が前記計量カップの底の中央に下方に向けて突設された摺動案内筒内に上下方向の相対摺動のみを許容する嵌合構造を介して設けられ、更に前記下部注出パイプはこの摺動案内筒の下端に連結されていて、前記回転内筒を回転させることにより、前記上部注出パイプを上昇或いは下降させ、前記計量カップ内の容量が大小変更されるように構成されたものである。
【００１４】
そして、第２発明の定量排出容器は、請求項２に記載されるように、容器本体の注出口にねじ部を介して気密に嵌着される取付け部とその上蓋を底として栓を兼用した有底の計量カップと、この計量カップの前記底を貫通して、上端が計量カップ内の上方に向かって延設され、上端部に注出孔が開口された上部注出パイプと、下端が容器本体内と連通されて前記上部注出パイプに連結された下部注出パイプとから構成されていて、前記計量カップは、前記栓の取付け部に上方に向って立ち上げられた円筒側枠と、この円筒側枠に対して相対回転のみ自在に内嵌合され、上端には回転操作部が設けられた回転内筒とを備え、かつ、前記上部注出パイプはこの回転内筒の中央に設けられたネジ部に螺合されるネジ部を周面に備えると共に、下部が前記計量カップの底の中央に下方に向けて突設された摺動案内筒内に上下方向の相対摺動のみを許容する嵌合構造を介して設けられ、更に前記下部注出パイプはこの摺動案内筒の下端に連結されていて、前記回転内筒を回転させることにより、前記上部注出パイプを上昇或いは下降させ、前記計量カップ内の容量が大小変更されるように構成されたものである。
【００１５】
また、前記第１，第２発明ともに、前記回転内筒の上端には外方に露呈する回転操作部が備わっているとともに、前記円筒側枠とこの回転内筒とには、一方に支持目盛が、他方には円筒側枠に対して回転内筒を回転させて得られる容積を表示する計量目盛が設けられていて、回転操作部を回転させて、支持目盛を所望の計量目盛に合致させることで、その合致した計量目盛に表示された容量の液体の計量ができるように構成されているものである。
【００１６】
更に、前記上部注出パイプの上下方向の相対摺動のみを許す嵌合構造は、前記摺動案内筒と、この摺動案内筒の内周面とこの摺動案内筒に嵌合された上部注出パイプの下端部の外周面との相対摺動面間の一方に設けられた突条と、他方に設けられたこの突条が嵌合される上下方向の凹溝とから構成されているか、上部注出パイプの下部の外周形状が横断面異径に形成されるとともに、前記摺動案内筒の内周面形状がこの上部注出パイプの横断面異径形状に合致する異径に形成されているかのいずれかの手段が採用される。
【００１７】
【作用】
以上のように構成された本発明に係る定量排出容器にあって、本第１発明に係る定量排出容器は、図１或いは図３に示されるように、前記回転内筒を円筒側枠に対して所望の量正・逆回転させれば、この回転量に応じて前記上部注出パイプが上下方向に所望の量昇降して、この上部注出パイプの注出孔とこの計量カップの底部までの距離が大小変更され、その時のこの注出孔の位置で計量カップ内に溜まる液体の量が機械的に大小設定される。つまり、計量カップが円筒側枠と底とによって有底の筒空間を備え、この筒空間の中に上下動する上部注出パイプが設けられていて、この上部注出パイプが回転内筒の回転作動に起因して上下動され、計量カップ内の計量容量が機械的に大小変更されるもので、従来の計量カップの計量容量が一定で計量には目視を必要とするもの、計量カップ全体が栓外方に露出された注出パイプ部分に対して上下動するもの、更には注出パイプが計量カップの底を貫いて相対的に上下動するもの等と違って、注出液体の計量は機械的に行え、また、計量液体が計量カップ外へ漏れ出すような計量カップと注出パイプとが相対摺動する構造を備えず、上部注出パイプがこの回転内筒の中央に設けられたネジ部に螺合されるネジ部を周面に備えると共に、下部が上下方向の相対摺動のみを許容する嵌合構造を介して設けられる構成を採用したことによって、上部注出パイプと下部注出パイプとを別体構造とする構成を採用できた。
【００１８】
また、本第２発明に係る定量排出容器は、前記第１発明によって奏せられる作用に加えて、更に、次のような作用を奏する。
つまり、回転内筒の上端部に設けられる回転操作部を手指で回転操作することで上部注出パイプが、この上部注出パイプと下部注出パイプとの連結を図るための摺動案内筒にガイドされながら上下動されて計量カップ内の液体収容容積が自在に変更され、計量容量の変更操作をスムーズに行うのに貢献する。
【００１９】
更に、上部注出パイプを上下動させるための構造が、前記円筒側枠に相対回転のみ自在に内嵌合された回転内筒とこの上部注出パイプの外周面とのネジ螺合手段を採用した点、併せてこの上部注出パイプの上下昇降の案内をこの上部注出パイプと下部注出パイプとの連結を図るための摺動案内筒が兼用した点は、液体計量のための構造の簡素化を図れるとともに、計量容量の変更操作性能を一層向上できる上で大きく貢献する。
【００２０】
また、本第１，第２発明はともに、図２に示されるように、円筒側枠と回転内筒との一方に支持目盛が、他方には円筒側枠に対して回転内筒を回転させて得られる容積を表示する計量目盛が設けられていて、外方に露呈された回転操作部を回転させて、支持目盛を所望の計量目盛に合致させることで、その合致した計量目盛に表示された容量の液体の計量ができるもので、支持目盛を、例えば３０mlや５０ml等の計量目盛に合致させるだけで、機械的に定量的な計量が行え、計量容量の変更操作を一層簡便に行うのに大きく貢献できる。
【００２１】
更に、本発明において、前記上部注出パイプの上下方向の相対摺動のみを許す嵌合構造として、図１に示されるように、上部注出パイプ下部の外周面と摺動案内筒の内周面との対向周面の一方に上下方向に沿って突設された突条と、他方にこの突条が嵌合されるように穿設された凹溝との嵌合構造、或いは、図５に示されるように、上部注出パイプ下部の外形形状を横断面異径に形成するとともに、前記摺動案内筒の内周面形状をこの上部注出パイプ下部の横断面異径形状に合わせて異径に形成した嵌合構造のいずれかを採用することで、本来的に必須の構成であるこの上部注出パイプと下部注出パイプとの連結を図るための摺動案内筒を上部注出パイプの昇降ガイドとして利用できる。
【００２２】
本発明は、前記計量カップを、容器本体の注出口へ気密に取付けられる栓体を一体に備える構成を採用することで、つまり、一つの部材の上面が計量カップの底に、また、下面が栓の蓋に構成されることで、更に一層の構成部品の削減に貢献できる。
【００２３】
更に、開閉自在なキャップは、前記計量カップを衛生的に使用するのに貢献する。
【００２４】
【発明の実施の形態】
以下、本発明の好適な一実施の形態を図面に基づいて説明する。
図１は本発明に係る定量排出容器の要部の拡大断面図で、容器本体１、つまりはスクイズボトルは、例えば合成樹脂等の可撓性物質で形成される。このスクイズボトル１の注出口２には栓３を兼用した計量カップ４が取付け部５に形成されたネジ部６とこの注出口２のネジ部７との螺合により気密に嵌着されている。従って、前記栓３は、前記取付け部５と前記計量カップ４の底部８とで構成され、この底部８が上蓋を兼ねる構成となっている。
【００２５】
前記計量カップ４は、基本的には、スクイズボトル１の注出口２へ取付けられる栓３の取付け部５上に上方に向かって立ち上げられた、透明な円筒側枠９と、上端に回転操作部１０を一体に備えてこの円筒側枠９の内側に相対回転自在に内嵌合された有底の透明な回転内筒１１と、更にこの回転内筒１１の底部１２の中央に設けられネジ筒１３に嵌合されて、前記回転操作部１０の回転操作に伴うこの回転内筒１１の回転によって上昇或いは下降自在に構成された、上端に注出孔１４が開口された上部注出パイプ１５と、更に、前記底部８の中央に下方に向かって一体に突設されていて、前記上部注出パイプ１５を上下動自在に案内する摺動案内筒１６と、この摺動案内筒１６の下端に結合され、下端がスクイズボトル１の底にまで達する長さに寸法設定された、可撓性の素材から成る下部注出パイプ１７とから構成されている。
【００２６】
前記円筒側枠９の内径と回転内筒１１の外径とは、相対回転を許容する範囲で略同一径に構成されている。また、この回転内筒１１の中央に突設されたネジ筒１３の内周面には軸線方向の全長にわたってネジ部１８が刻設されているとともに、前記上部注出パイプ１５の外周面には、下部の所定の範囲を除いてそれよりも上方にネジ部１９が設けられている。
【００２７】
また、前記計量カップ４の底部８の中央に設けられた前記摺動案内筒１６内に前記上部注出パイプ１５の下端部が嵌入されているとともに、この上部注出パイプ１５の下端部周面には、図４に示されるように、周方向には相互に１８０°位相を異ならせて半径方向に突出する突条２０が一体に設けられているとともに、前記摺動案内筒１６の内周面には、この突条２０に嵌合する上下方向の凹溝２１が同様に周方向１８０°位相を異ならせて設けられている。従って、前記回転内筒１１を回転させることによって、この回転内筒１１とのネジ螺合を介してこの上部注出パイプ１５は回転されようとするが、この上部注出パイプ１５の突条２０が前記凹溝２１に嵌合されているので、この上部注出パイプ１５は回転されることなく、上下方向にのみ昇降移動されることとなる。
【００２８】
前記摺動案内筒１６の上下寸法は、希望する容量の最小量（図例では３０ml）から最大量を収容するに足る容積が得られるに足る、回転内筒１１の底部１２と上部注出パイプ１５の注出孔１４との相対距離範囲に設定されている。従って、図１に示されるように、この上部注出パイプ１５を最上方にまで上昇させると、最多量の５０mlを注出できるに足る容積が形成され、また上下方向の中間部に位置させると、中間量の４０mlを注出できるに足る容積が形成され、そして最下方まで下降させると、最小量の３０mlを注出できるに足る容積が形成されることになる。
【００２９】
また、前記上部注出パイプ１５の下部の所定の範囲を除いてそれよりも上方にネジ部１９が設けられている構成に言うところの、この所定の範囲とは、図１に示されるように、前記突条２０の上下寸法に等しい長さを意味する。また、この突条２０の外径寸法は前記ネジ部１９の外径寸法と同等に形成されているので、上部注出パイプ１５が最上方まで上昇して最多量の５０mlを注出できるに足る容積が形成される所定位置に至った時、この突条２０が前記回転内筒１１の底部１２に当接されて上部注出パイプ１５のそれ以上の上昇が阻止される構造となっている。従って、前記回転内筒１１の底部１２とこの突条２０とが前記上部注出パイプ１５の最上昇位置のストッパーとして機能する。
【００３０】
前記回転操作部１０は、前記回転内筒１１の上端よりもやゝ下方部位の周囲に一体に連設されていて、前記円筒側枠９の上端から外側を巻き込む形で、鍔片２２とその外周縁から下方に一体に垂下される操作リング（ダイヤル部）２３が一体に備わって、断面形状逆Ｌ字状に形成され、この操作リング（ダイヤル部）２３の下端には、この円筒側枠９の周面に形成された離脱防止のための嵌合周溝２４内に嵌合される内向きの係止突条２５が一体に設けられ、また、図２に示されるように、前記操作リング（ダイヤル部）２３の表面には、支持目盛としての指示マーク２６が設けられている。
【００３１】
また、図２に示されるように、前記円筒側枠９の上端近くの表面には、等間隔をおいて複数の計量目盛２７が表示されている。この計量目盛２７は、前記回転操作部１０を回転させることによって、上部注出パイプ１４の注出孔１３から回転内筒１１の底部１２までの距離の変化によってもたらされる計量カップ４内の定量的な容量変化量に対応した目盛である。図２に示される例では、３０ml、４０ml、５０mlの、三段階で容量を可変できることが明らかである。
【００３２】
従って、例えば、３０mlの液体を注出したい場合には、図１に示される状態から、前記操作リング（ダイヤル部）２３に表示されている指示マーク２６を、この計量目盛２７の３０mlに合致する位置にくるように、前記回転操作部１０を回転させる。この操作によって、前記回転内筒１１が回転され、上部注出パイプ１５が下降して、図３に示されるように、計量カップ４内に３０mlの液体を満たすに足りる空間が形成されるのである。
【００３３】
また、前記計量カップ４には、図３に示されるように、キャップ２８がヒンジ２９を介して一体的に設けられている。このキャップ２８には、その中央に保護筒部３０が一体に突設されているとともに、前記鍔片２２の中間には上方に向かって立ち上がる、前記キャップ２８の係止用の嵌合周壁３１が一体に立設されている。従って、キャップ２８が前記嵌合周壁３１に係合されて計量カップ４を閉塞している状態では、このキャップ２８が不用意に開放される恐れがないことは言うまでもない。前記キャップ２８は必要に応じて設けられるものであるが、これを備えることによって、計量カップ４内へ塵埃等が入り込むのをうまく防止し、併せて前記の通りの保護筒部３０などを備えることで一層商品価値を高めることができる。
【００３４】
また、前記保護筒部３０は、前記上部注出パイプ１５の上端部から注出孔１４の下端縁に至る範囲にわたって嵌合されて、その注出孔１４を閉塞するに足る上下寸法に形成されている。従って、前記上部注出パイプ１５が最上昇位置に至った時に、キャップ２８が閉塞されると、上部注出パイプ１５の上端部から前記注出孔１４が閉塞されるに足る範囲の外周全域がこの保護筒部３０で囲撓されるので、この注出孔１４の液密が保持され、たとえスクイズボトル１が転倒したり、或いは不用意にスクイズボトル１の本体部分が押圧されてスクイズボトル１内の液体がこの注出孔１４から計量カップ４内に溢れ出ようとしても、これを上手く阻止できる。
【００３５】
次に以上実施の形態で説明された構成を備える本発明の定量排出容器の使用の仕方を説明する。
予め、操作リング２３を回転させて、その指示マーク２６を円筒側枠９に表示された計量目盛２７の何れかに合致させることによって、上部注出パイプ１５を上下動させる。
【００３６】
次にスクイズボトル１を鉛直方向に沿うように保持しながら、手指等でこのスクイズボトル１の胴部等を適宜の時間（数秒間）押圧することによって、スクイズボトル１内の液体Ａを、先ず下部注出パイプ１７、摺動案内筒１６、そして上部注出パイプ１５を介して、その上端部の注出孔１４から計量カップ４内に注入させる。
【００３７】
そして、注入される液体の液面が、理想的には概ね前記注出孔１３を越える位置に至ったところで、スクイズボトル１への押圧を止める。すると、スクイズボトル１はそれ自体の弾撥力により、押圧されて凹んだ部分が元の形状に復帰しようとする。その際スクイズボトル１の内部圧力は負となるので、その吸引力によって計量カップ４内の注出液体は注出孔１４を介してスクイズボトル１内へ吸い込まれる。そして、この吸引は前記注出液体の液面が注出孔１４の下端縁と同一高さになるまで行われ、計量カップ４内には所望通りの定量の液体Ｂが残る。その後は注出孔１４から引き続き大気が吸引されてスクイズボトル１は液体注出前の形状に復帰することとなる。この状態からスクイズボトル１を傾けることによって、前記所望の一定量の液体が計量カップ４から排出される。
【００３８】
次に、図５に示される構造は、前記上部注出パイプ１５の上下昇降を司る別の手段を、また、図６はこの上部注出パイプ１５の回り止めを図る別の手段を夫々示したもので、具体的には以下の構造を備える。
まず、前記上部注出パイプ１５の上下昇降を司る別の手段としては、図５に示されるように、前記回転内筒１１の上方に中央に回転操作用の摘み３２が設けられたものである。この摘み３２はこの回転内筒１１の上端に周方向複数個のアーム３３を介して中央に一体的に形成されたものである。前記摘み３２が前記回転内筒１１の中央に一体的に設けられるためには、例えば摘み３２と各アーム３３とが一体に成形され、各アーム３３の周縁がこの回転内筒１１の上端縁に接着剤や熱溶着等によって適宜に固着連設される手段が採用される。また、それ以外にも前記摘み３２とは別体で前記各アーム３３が一体に成形され、その中心部にこの摘み３３が、例えば接合、嵌合或いはビス止め等の手段により適宜に固着連設され、各アーム３２の周縁が、前記と同様に、この回転内筒１１の上端縁に接着剤や熱溶着等によって適宜に固着連設される手段が採用される。尚、図中３４は、円筒側枠９の上端部の内周面に形成された嵌合凹溝で、前記回転内筒１１の上端に形成された外向き鍔３５が嵌合されて円筒側枠９からこの回転内筒１１が離脱するのを防止する。また、前記支持マーク２６は前記外向き鍔３５の上面に表示されるとともに、計量目盛２７は、円筒側枠９の上縁に表示されている。
【００３９】
また、前記上部注出パイプ１５の回り止めを図る別の手段としては、図６に示されるように、上部注出パイプ１５と摺動案内筒１６のとの間に形成された突条２０とこれが嵌合される凹溝２１とによって形成される手段に代えて、前記上部注出パイプ１５の下端部の外周形状が横断面形状楕円形に形成されるとともに、この楕円形状に合致させて、前記摺動案内筒１６の内周面形状が楕円形に形成された構造を採用できる。
【００４０】
更に、前記回転円筒１１は、図１乃至図６では、底部１２が一体に備わった、所謂有底の筒体で構成されているが、この底部１２が例えば周方向に所定間隔置きで配された複数個のアーム状に構成された構造のものも採用できる。この構成が採用される場合は、スクイズボトル１から計量カップ４内に注出される液体は計量カップ４の底８まで入ることになる。
【００４１】
【発明の効果】
以上説明したように本第１発明は、計量カップが円筒側枠と底とによって有底の筒空間を備えていて、この筒空間の中で、回転内筒の回転作動によって、上部注出パイプを上下動させて、この上部注出パイプの注出孔から回転内筒の底部迄の距離を大小変更させることによって、計量カップ内の計量容量を機械的に大小変更することができるようにしたから、従来の計量カップの計量容量が一定で、しかも計量には注意深い目視を必要とするもの、また、計量カップ全体が栓外方に露出された注出パイプ部分に対して上下動するもの、更には注出パイプが計量カップの底を貫いて相対的に上下動するもの等と違って、目視を必要とすることなく、必要量の液体の計量は機械的に行えるから、計量が非常に簡便でスピーディーに行え、また、計量液体を無駄にする恐れもなくなった。
【００４２】

BACKGROUND OF THE INVENTION
The present invention relates to a quantitative discharge container used for measuring and quantitatively discharging liquids such as squeeze bottle liquid medicine and mouth washing liquid, cosmetics, as well as detergents and washing softeners.
[0002]
[Prior art]
Conventionally, this type of quantitative discharge container is generally marketed as a so-called overflow-type fixed discharge container as shown in FIG. The specific structure of this container is that a cylindrical measuring cup 04 that also serves as a stopper and has a spout 03 at the top of the mouth part 02 of the container main body 01 is mounted, and a bottom 05 of the measuring cup 04 is An upper pouring pipe 06 extending upward from the bottom portion 05 is provided, and the upper end of the lower pouring pipe 07 extending to the bottom of the container body 01 is fitted into the lower portion of the upper pouring pipe 06. The measuring cup 04 is made of a transparent resin, and a measuring scale 08 is provided on the peripheral surface thereof. Further, the opening 06A at the upper end of the upper pouring pipe 06 is provided at the same level as the maximum weighing scale 08A.
[0003]
Therefore, in order to pour out a predetermined amount of liquid from such an overflow type quantitative discharge container, first, the body part 09 of the container body 01 is pressed by hand, and the content liquid 0A is poured from the lower pour pipe 07 into the upper part. Overflow into measuring cup 04 via outlet pipe 06. However, particularly important at this time, it is necessary to carefully confirm whether or not the level of the liquid poured into the measuring cup 04 correctly matches the required measuring scale 08 by visual inspection. Next, when the pressing force of the container body 01 is released when the liquid level and the measurement scale 08 coincide with each other, the liquid in the dispensing pipe 06 is sucked into the container body 01. As a result, a predetermined amount of liquid is poured into the measuring cup 04. The liquid 0B thus measured is poured out from the spout 03 of the measuring cup 04 by tilting the container body 01.
[0004]
In addition to the visual means described above, as the quantitative discharge means, although not shown, by making the measuring cup vertically changeable with respect to the container body, the bottom face of the measuring cup and the upper opening of the upper dispensing pipe Has been proposed in which the distance from the upper end opening to the bottom surface of the measuring cup is made variable by changing the relative vertical position of the liquid so that a fixed amount of liquid is dispensed (as an example, actual fairness 2-24768). No. publication).
[0005]
Further, as another means, although not shown, a measuring cup disposed on the portion of the container body that is attached to the spout and a pouring pipe that penetrates the bottom of the measuring cup and reaches the bottom of the container body. A measuring mechanism is configured, and the measuring cup has a cylindrical shape with a bottom, and a thread portion is formed on the outer periphery thereof. The lower end of the pouring tube is opened and the upper end is closed, and the upper end is a screw of the measuring cup. It is fixed to the upper end of the mounting cylinder that is externally screwed to the part via an arm, and is formed so that it can move up and down as the mounting cylinder rotates up and down. A discharge hole is provided in the peripheral surface near the upper end. This discharge hole is disposed in the measuring cup, and the distance from the discharge hole to the bottom of the measuring cup is increased or decreased as the mounting cylinder rotates. By pouring the desired liquid into the measuring cup That means have been proposed (e.g., see JP Utility Model 63-35973).
[0006]
[Problems to be solved by the invention]
However, among the conventional quantitative discharge containers, the first presented means is basically that the measuring volume of the measuring cup is set to a fixed amount. Although it can only be done, it tries to make it easier to use by providing a weighing scale, but in reality it is difficult to obtain the convenience as expected.
In other words, since it is necessary to carefully check whether or not the desired scale of measurement and the liquid level of the overflowing liquid are correctly matched with each other, weighing is very troublesome and wrong. If the content liquid overflows beyond the desired amount, the excess liquid cannot be returned to the container body again, so that the excess liquid must be discarded and wasted.
[0007]
In addition, in the conventional means shown second, it is necessary to move the entire measuring cup up and down with respect to the upper pouring pipe, so that the operation takes time and in particular, the measuring cup is raised to the top. Sometimes, only the pouring pipe has a means to support the weight of the measuring cup, so that the supporting of the measuring cup becomes unstable. Further, the upper pouring pipe protrudes upward through the lid of the container body. In addition, since the screw provided at the bottom of the measuring cup is screwed to the screw of the upper pouring pipe that protrudes upward from the lid, the measuring cup is supported even though it is a fluid-tight screw fitting. Since the structure is unstable, the liquid from the screw portion is likely to leak, and once leaked, the liquid overflows out of the container, resulting in contamination of the container and the surroundings.
[0008]
And, in the third conventional means shown, the pouring pipe extends through the bottom of the measuring cup to the bottom of the container body, but the airtightness between the pouring pipe and the bottom of the measuring cup. For holding, it is necessary to form the pouring tube and the bottom of the measuring cup with a synthetic resin flexible material, so that other parts, for example, the mounting tube and the pouring tube are joined to the mounting tube. Arm, peripheral wall of measuring cup, hinge cap, mounting part for screwing measuring cup to outlet of container body, etc., and especially for mounting cylinder, arm and mounting part molded integrally with this pouring pipe Consistency is very difficult, and there is a problem that integral molding is not suitable, which is one of the great advantages of manufacturing with synthetic resin. In addition, the structure is difficult to manufacture, such as closing the upper end of the extraction pipe, forming a discharge hole in the peripheral side wall below it, and attaching the upper end of the extraction pipe to the mounting cylinder via the arm. It has become.
[0009]
In view of the above, the present invention has studied various problems of the conventional quantitative discharge container as described above, and as a result, in this kind of quantitative discharge container, the metered capacity is determined to be constant. Therefore, the inventors have found that it is an essential requirement that the weighing capacity is variable, and have intensively studied to develop the present invention.
Accordingly, a first object of the present invention is to provide a metering discharge container that can easily measure a desired amount without requiring visual inspection while allowing the metering capacity to be variable, and that does not cause liquid to leak from the metering cup. The point is to provide.

[0024]
DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is an enlarged cross-sectional view of a main part of a quantitative discharge container according to the present invention, and a container body 1, that is, a squeeze bottle is formed of a flexible material such as a synthetic resin. The spout 2 of the squeeze bottle 1 is fitted with a measuring cup 4 that also serves as a stopper 3 in an airtight manner by screwing a screw portion 6 formed on the attachment portion 5 with a screw portion 7 of the spout 2. . Accordingly, the stopper 3 is constituted by the mounting portion 5 and the bottom portion 8 of the measuring cup 4, and the bottom portion 8 also serves as an upper lid.
[0025]
The measuring cup 4 basically has a transparent cylindrical side frame 9 raised upward on an attachment portion 5 of a stopper 3 attached to the spout 2 of the squeeze bottle 1 and a rotational operation at the upper end. A bottomed transparent rotating inner cylinder 11 that is integrally provided with a portion 10 and is fitted inside the cylindrical side frame 9 so as to be relatively rotatable, and a screw provided at the center of the bottom 12 of the rotating inner cylinder 11. An upper pouring pipe 15 which is fitted to the tube 13 and can be raised or lowered by the rotation of the rotating inner tube 11 in accordance with the rotation operation of the rotating operation unit 10 and has an pouring hole 14 opened at the upper end. And a sliding guide tube 16 integrally projecting downward from the center of the bottom portion 8 to guide the upper pouring pipe 15 in a vertically movable manner, and a lower end of the sliding guide tube 16 The lower end of the squeeze bottle 1 reaches the bottom. And a size set, made of a flexible material lower pouring pipe 17. to.
[0026]
The inner diameter of the cylindrical side frame 9 and the outer diameter of the rotating inner cylinder 11 are configured to have substantially the same diameter within a range that allows relative rotation. A screw portion 18 is engraved on the inner peripheral surface of the screw cylinder 13 projecting from the center of the rotating inner cylinder 11 over the entire length in the axial direction, and on the outer peripheral surface of the upper dispensing pipe 15. A screw portion 19 is provided above the lower portion except for a predetermined range.
[0027]
A lower end portion of the upper pouring pipe 15 is fitted into the sliding guide tube 16 provided at the center of the bottom portion 8 of the measuring cup 4, and a lower end portion peripheral surface of the upper pouring pipe 15 is inserted. As shown in FIG. 4, protrusions 20 projecting in the radial direction with different phases by 180 ° are integrally provided in the circumferential direction, and the inner circumference of the sliding guide cylinder 16 is integrally provided. On the surface, vertical grooves 21 fitted in the ridges 20 are similarly provided with a phase difference of 180 ° in the circumferential direction. Accordingly, by rotating the rotating inner cylinder 11, the upper pouring pipe 15 tends to be rotated through screw threading with the rotating inner cylinder 11, but the protrusion 20 of the upper pouring pipe 15 is rotated. Is fitted in the concave groove 21, the upper pouring pipe 15 is moved up and down only in the vertical direction without being rotated.
[0028]
The vertical dimension of the sliding guide tube 16 is such that the volume sufficient to accommodate the maximum amount from the minimum amount (30 ml in the illustrated example) of the desired capacity is obtained, and the bottom portion 12 and the upper pouring pipe of the rotating inner tube 11. It is set to a relative distance range with respect to 15 extraction holes 14. Therefore, as shown in FIG. 1, when the upper pouring pipe 15 is raised to the uppermost position, a volume sufficient to pour out the largest amount of 50 ml is formed, and when the upper pouring pipe 15 is positioned at the middle in the vertical direction. A volume sufficient to dispense an intermediate amount of 40 ml is formed, and when lowered to the lowest position, a volume sufficient to dispense a minimum amount of 30 ml is formed.
[0029]
In addition, the predetermined range in the configuration in which the screw portion 19 is provided above a predetermined range below the upper pouring pipe 15 is as shown in FIG. , Means a length equal to the vertical dimension of the ridge 20. Further, since the outer diameter dimension of the ridge 20 is formed to be equal to the outer diameter dimension of the screw portion 19, the upper pouring pipe 15 is raised to the uppermost position, so that a maximum amount of 50 ml can be poured. When reaching the predetermined position where the volume is formed, the protrusion 20 is brought into contact with the bottom 12 of the rotating inner cylinder 11 to prevent the upper pouring pipe 15 from further rising. Therefore, the bottom portion 12 of the rotating inner cylinder 11 and the protrusion 20 function as a stopper at the highest position of the upper pouring pipe 15.
[0030]
The rotary operation unit 10 is integrally connected to the periphery of the lower part of the flange slightly from the upper end of the rotating inner cylinder 11 and is wound around the outer side from the upper end of the cylindrical side frame 9, An operation ring (dial portion) 23 that is integrally suspended downward from the outer peripheral edge is integrally provided and formed in an inverted L-shaped cross section. The cylindrical side frame is formed at the lower end of the operation ring (dial portion) 23. 9 is integrally provided with an inward engagement protrusion 25 which is fitted into a fitting circumferential groove 24 formed on the peripheral surface for preventing separation, and as shown in FIG. On the surface of the ring (dial portion) 23, an instruction mark 26 as a support scale is provided.
[0031]
Further, as shown in FIG. 2, a plurality of weighing scales 27 are displayed on the surface near the upper end of the cylindrical side frame 9 at equal intervals. This measuring scale 27 is a quantitative measure in the measuring cup 4 caused by a change in the distance from the pouring hole 13 of the upper pouring pipe 14 to the bottom 12 of the rotating inner cylinder 11 by rotating the rotary operation unit 10. The scale corresponds to the amount of change in capacity. In the example shown in FIG. 2, it is apparent that the volume can be varied in three stages of 30 ml, 40 ml and 50 ml.
[0032]
Therefore, for example, when 30 ml of liquid is to be dispensed, the indication mark 26 displayed on the operation ring (dial part) 23 matches the 30 ml of the measuring scale 27 from the state shown in FIG. The rotation operation unit 10 is rotated so as to reach the position. By this operation, the rotating inner cylinder 11 is rotated and the upper pouring pipe 15 is lowered to form a space sufficient to fill 30 ml of liquid in the measuring cup 4 as shown in FIG. .
[0033]
Further, as shown in FIG. 3, the measuring cup 4 is integrally provided with a cap 28 via a hinge 29. The cap 28 is integrally provided with a protective cylinder portion 30 at its center, and a fitting peripheral wall 31 for locking the cap 28 rises upward in the middle of the flange piece 22. It is erected integrally. Therefore, it goes without saying that in the state where the cap 28 is engaged with the fitting peripheral wall 31 and the measuring cup 4 is closed, there is no fear that the cap 28 is inadvertently opened. The cap 28 is provided as necessary. By providing the cap 28, dust and the like can be well prevented from entering the measuring cup 4, and the protective cylinder 30 as described above is provided. Can further increase the product value.
[0034]
The protective cylinder portion 30 is fitted over a range from the upper end portion of the upper pouring pipe 15 to the lower end edge of the pouring hole 14 and is formed in a vertical dimension sufficient to close the pouring hole 14. ing. Therefore, when the cap 28 is closed when the upper pouring pipe 15 reaches the highest position, the entire outer periphery of the range sufficient to close the pouring hole 14 from the upper end of the upper pouring pipe 15 is obtained. Since it is surrounded by the protective cylinder 30, the liquid tightness of the pouring hole 14 is maintained, and even if the squeeze bottle 1 falls over or the body part of the squeeze bottle 1 is carelessly pressed, the squeeze bottle 1 Even if the liquid inside overflows into the measuring cup 4 from the pouring hole 14, this can be prevented well.
[0035]
Next, how to use the metering discharge container of the present invention having the configuration described in the above embodiment will be described.
The operation ring 23 is rotated in advance, and the upper mark pipe 15 is moved up and down by matching the indication mark 26 with one of the weighing scales 27 displayed on the cylindrical side frame 9.
[0036]
Next, while holding the squeeze bottle 1 along the vertical direction, the liquid A in the squeeze bottle 1 is firstly pressed by pressing the body of the squeeze bottle 1 with a finger or the like for an appropriate time (several seconds). It is poured into the measuring cup 4 from the pouring hole 14 at the upper end via the lower pouring pipe 17, the sliding guide cylinder 16, and the upper pouring pipe 15.
[0037]
Then, when the liquid level of the liquid to be injected has reached a position that substantially exceeds the pouring hole 13 ideally, the pressing to the squeeze bottle 1 is stopped. Then, the squeeze bottle 1 tries to return to its original shape due to its own elastic force. At that time, since the internal pressure of the squeeze bottle 1 becomes negative, the liquid drawn out of the measuring cup 4 is sucked into the squeeze bottle 1 through the discharge hole 14 by the suction force. This suction is performed until the liquid level of the poured liquid becomes the same height as the lower end edge of the dispensing hole 14, and a desired amount of liquid B remains in the measuring cup 4. After that, the atmosphere is continuously sucked from the pouring hole 14, and the squeeze bottle 1 returns to the shape before liquid pouring. By tilting the squeeze bottle 1 from this state, the desired amount of liquid is discharged from the measuring cup 4.
[0038]
Next, the structure shown in FIG. 5 shows another means for controlling the up and down movement of the upper pouring pipe 15, and FIG. 6 shows another means for preventing the upper pouring pipe 15 from rotating. Specifically, it has the following structure.
First, as another means for controlling the up and down movement of the upper pouring pipe 15, as shown in FIG. 5, a rotary operation knob 32 is provided at the center above the rotating inner cylinder 11. . The knob 32 is formed integrally with the upper end of the rotating inner cylinder 11 at the center via a plurality of arms 33 in the circumferential direction. In order for the knob 32 to be provided integrally at the center of the rotating inner cylinder 11, for example, the knob 32 and each arm 33 are formed integrally, and the peripheral edge of each arm 33 is the upper edge of the rotating inner cylinder 11. A means that is fixedly connected as appropriate by an adhesive, heat welding, or the like is employed. In addition, the arms 33 are formed integrally with the knob 32 separately from the knob 32, and the knob 33 is fixedly connected to the center of the arm 33 by means of, for example, joining, fitting or screwing. In the same manner as described above, a means is adopted in which the peripheral edge of each arm 32 is appropriately fixedly connected to the upper end edge of the rotating inner cylinder 11 by an adhesive, heat welding, or the like. In the figure, reference numeral 34 denotes a fitting groove formed on the inner peripheral surface of the upper end portion of the cylindrical side frame 9, and an outward flange 35 formed on the upper end of the rotating inner cylinder 11 is fitted to the cylindrical side. The rotation inner cylinder 11 is prevented from being detached from the frame 9. In addition, the support mark 26 is displayed on the upper surface of the outward flange 35, and the measurement scale 27 is displayed on the upper edge of the cylindrical side frame 9.
[0039]
Further, as another means for preventing the upper pouring pipe 15 from rotating, as shown in FIG. 6, a ridge 20 formed between the upper pouring pipe 15 and the sliding guide tube 16 is used. Instead of the means formed by the recessed groove 21 into which this is fitted, the outer peripheral shape of the lower end portion of the upper pouring pipe 15 is formed in a cross-sectional shape ellipse, and matched with this elliptical shape, A structure in which the inner peripheral surface shape of the sliding guide cylinder 16 is formed in an elliptical shape can be adopted.
[0040]
Further, in FIG. 1 to FIG. 6, the rotating cylinder 11 is constituted by a so-called bottomed cylinder body integrally provided with the bottom portion 12, and the bottom portion 12 is arranged at predetermined intervals in the circumferential direction, for example. A structure having a plurality of arms can also be used. When this configuration is adopted, the liquid poured out from the squeeze bottle 1 into the measuring cup 4 enters the bottom 8 of the measuring cup 4.

【The invention's effect】
As described above, according to the first aspect of the present invention, the measuring cup is provided with a cylindrical space having a bottom by the cylindrical side frame and the bottom, and the upper dispensing pipe is rotated by the rotation operation of the rotating inner cylinder in the cylindrical space. The measuring capacity in the measuring cup can be changed mechanically by changing the distance from the pouring hole of the upper pouring pipe to the bottom of the rotating inner cylinder. From the above, the measuring capacity of the conventional measuring cup is constant, and careful weighing is required for the weighing, and the measuring cup is moved up and down with respect to the pouring pipe part exposed to the outside of the stopper, Furthermore, unlike a pipe that moves up and down relatively through the bottom of the measuring cup, the required amount of liquid can be measured mechanically without the need for visual inspection. Simple and speedy, and Fear to waste liquid was also lost.
[0042]
In addition, since the liquid can be mechanically measured by rotating the rotating inner cylinder forward and backward, handling and measuring operations are very easy and convenient to use, and a cylindrical space is formed with a measuring cup at the bottom. Because the upper pouring pipe is moved up and down in this cylindrical space, there is no need to slide the pouring pipe and the bottom of the measuring cup relative to each other, and the measuring cup and the pouring pipe slide relative to each other. Unlike the structure, there is no risk of liquid leakage, and therefore there is no risk of inadvertently fouling the container and its surroundings. In this respect, it is possible to provide a quantitative discharge container that is easy to handle and has high commercial value.
[0043]
Further, in addition to the above-described effects brought about by the first invention, the quantitative discharge container according to the second invention has an upper portion by rotating the rotation operation part provided at the upper end of the rotating inner cylinder with fingers. The dispensing pipe is moved up and down while being guided by a sliding guide cylinder for connecting the upper dispensing pipe and the lower dispensing pipe, so that the liquid storage volume in the measuring cup is freely changed, and the measuring capacity is reduced. Since the change operation can be performed smoothly, the weighing operation is remarkably easy, the change operation of the weighing capacity can be easily performed, and the structure for moving the upper pouring pipe up and down is easy. Adopting screw screwing means between the rotating inner cylinder fitted inside the side frame so as to allow only relative rotation and the outer peripheral surface of the upper pouring pipe, the upper and lower pipes are guided up and down. Extraction pipe and bottom note Easy to manufacture because the sliding guide cylinder for connecting to the pipe is combined to simplify the structure for measuring liquid and to improve the measuring capacity changing operation performance. In addition, the structure for weighing can be simplified as much as possible, and there is also an advantage that it can be provided economically.
[0044]
Further, both the first and second inventions can automatically achieve quantitative measurement of the volume of liquid displayed on the matched measurement scale by matching the support scale with a desired measurement scale. The operation of changing the measuring capacity can be performed more easily, and a high-value-added quantitative discharge container can be provided.
[0045]
Further, according to the first and second inventions, as the fitting structure that allows only the relative sliding in the vertical direction, the outer peripheral surface of the upper pouring pipe, the upper pouring pipe, and the lower pouring pipe that are necessarily provided. By making the peripheral surface opposite to the inner peripheral surface of the sliding guide cylinder for connection with the cross-sectionally different diameter shape, the vertical movement can be guided well while simply preventing the rotation of the lifting bottom part, The structure of the measuring cup can be further simplified, and it can be manufactured and provided more economically.
[0046]
In both the first and second inventions, the measuring cup is integrally provided with a stopper that is airtightly attached to the spout of the container body, that is, the upper surface of one member is a measuring cup. By forming the bottom and the bottom surface of the stopper lid, it is possible to contribute to further reduction in the number of components, and to provide a more economical and simpler structure.
[0047]
Furthermore, a measuring cup can be used hygienically by providing a cap.
