Description

【０００１】
【発明の属する技術分野】
本発明は、粘度の比較的高いクリーム状の内容物を、手動ポンプを利用して注出する注出容器に関するものである。
【０００２】
【従来の技術】
クリーム状内容物を、手動ポンプを利用して注出するこの種の注出容器の従来技術として、有底筒状の容器本体に、該容器本体の内底に向けて吸上開口をもつ吸上げパイプを連結したポンプ機構を設け、前記容器本体内に、該吸上げパイプに対して摺動可能に挿通し、内容物の吸い上げにともなって、内容物の液面に密着して吸上げパイプに沿って移動する押え蓋を設けたものが知られている。
【０００３】
この押え蓋は、容器本体内の内容物が、流動性の悪いクリーム状物であるため、その吸い上げに伴って、吸上げパイプの吸上開口が位置する下端から内容物の上面に至る空孔が吸上げパイプの周囲に形成され、その結果、この空孔を通過した空気の混入により、内容物の円滑な注出が阻害されてしまうことを防止するためのものである。押え蓋で、内容物の上面を押えることにより、手動ポンプの内容物の吸い上げに伴う負圧の影響を、内容物全体に均一に作用させ、これにより内容物の吸い上げに伴う負圧が内容物の一部に偏って作用することにより形成される空孔の発生を阻止して、内容物の良好な注出動作を維持する。
【０００４】
また、内容物の粘度が大きい場合には、内容物の吸い上げに伴う、負圧の偏った作用時間が長く、これにより押え蓋自体が変形してしまう恐れがあるので、押え蓋の主体部分を硬質材製とし、吸上げパイプに密接する部分（内周端縁部分）を軟質弾性材製とすることにより、負圧により変形することなく、吸上げパイプに対する密摺動可能な組付きを維持できるようにしている。
【０００５】
特開２０００−２１９２８４号公報には、押え蓋を、リング板状の硬質材製の蓋板と、該蓋板の内周縁に密に組付いて、吸上げパイプに緩く外嵌する円筒状の内筒片の内周面下端に、内鍔状のシール片を周設したポリエステル系エラストマー製のシールリングと、から構成した注出容器が開示されている。
【０００６】
前述の注出容器は、シールリングの内筒片に設けたシール片が、中央側を上昇傾斜させた状態で吸上げパイプの外周面に弾力的に密摺接し、負圧が作用した際の吸上げパイプに対するシール片の圧接を強めて空気の下方への通過を確実に阻止するとともに、シールリングの内筒片に組付いて内容物の上面の略全域を覆っている蓋板が、内容物の吸い上げに伴って不均一に作用する負圧を変形することなく受け止めて、蓋板が略水平姿勢を保持しながら内容物の上面全域を略均一に押圧し、流動性の悪いクリーム状内容物を最後まで円滑かつ確実に注出できるようにしている。
【０００７】
押え蓋が下降変位する際に、負圧の不均一な作用により押え蓋が傾くことがあるが、手動ポンプの吸上げパイプに対向する押え蓋部分は、ポリエステル系エラストマー製のシールリングだけであるので、例え傾いても押え蓋が吸上げパイプに弾性的に押圧されるだけで、カジリ状に引っ掛かることはなく、押え蓋を円滑かつ確実に下降変位することになる。
【０００８】
【発明が解決しようとする課題】
しかしながら、クリーム状内容物を充填した注出容器が、輸送途中等において傾倒状態となった場合、吸上げパイプに密摺接しているシール片のみでは、吸上げパイプに対する押え蓋の傾斜を防止できず、吸上げパイプに対して押え蓋が傾斜して、蓋板と容器本体の内壁との隙間が大きくなり、この隙間から粘度の大きいクリーム状の内容物が蓋板を越えて押え蓋の上部に流動する、と云う問題がある。
【０００９】
内容物が、流動性の悪いクリーム状物であるがゆえに、一度蓋板を越えて押え蓋よりも上部に流動してしまうと、傾倒状態の注出容器を起立させても、内容物が押え蓋の上部に留まったまま下部には戻らず、内容物が押え蓋の上部に残存したまま、内容物を最後まで使い切ることができない、と云う問題がある。
【００１０】
また、蓋板を越えて押え蓋の上部に流動した粘度の高い内容物は、注出容器を起立させても下部に戻らないため、押え蓋と内容物との間に空孔が発生して、押え蓋が傾斜した状態のままとなり、傾斜した押え蓋では、内容物の上面全域を略均一に押圧することができないため、内容物の吸い上げに伴って発生する不均一な負圧が内容物の上面に偏って作用し、流動性の悪い内容物の円滑な注出が阻害される、と云う問題を生じる。
【００１１】
そこで、本発明は、上述の問題点を解消すべく創案されたもので、手動ポンプを有する容器本体内に内容物の押え蓋を設けた注出容器において、軟質弾性材製のシールリングの形状を保持するとともに、押え蓋の傾斜を防止することを技術的課題とし、もって粘度の大きいクリーム状内容物を最後まで円滑かつ確実に注出できる注出容器を提供することを目的とする。
【００１２】
【課題を解決するための手段】
上記技術的課題を解決する本発明の内、請求項１記載の発明の手段は、
クリーム状内容物を収納する壜体状の容器本体の口部に、内容物を吸い上げて注出する手動ポンプを装着し、容器本体内に、クリーム状内容物上に載置するリング板状の押え蓋を昇降変位可能に装着した注出容器であること、
押え蓋を、リング板状をした硬質材製の蓋板と、該蓋板の内周縁に密に組付いて、手動ポンプの吸上げパイプに緩く外嵌する円筒状の内筒片の内周面下部に、吸上げパイプの外周面に弾力的に密摺接して、空気の下方への通過を防止する内鍔状のシール片を周設した軟質弾性材製のシールリングと、シールリングの内筒片の少なくとも上部に不動に組付く硬質材製のリング状の傾斜防止筒とから構成したこと、
該傾斜防止筒の内径を吸上げパイプの外径よりも僅かに大きい値に設定したこと、にある。
【００１３】
請求項１記載の発明にあっては、シールリングの内筒片の少なくとも上部に、硬質材製のリング状の傾斜防止筒を不動に組付けたため、注出容器が傾倒状態となった場合に、吸上げパイプの外径よりも僅かに大きい値に設定した内径を有する傾斜防止筒が吸上げパイプの外周面に当接し、シールリングを支持するため、押え蓋全体の傾斜を防止することができる。
【００１４】
また、内容物の吸い上げに伴う不均一な負圧が、押え蓋に作用した場合であっても、硬質材製の傾斜防止筒が吸上げパイプの外周面に当接して、軟質弾性材である軟質弾性材製のシールリングを支持するため、押え蓋の傾斜を確実に防止することができ、吸上げパイプに対して蓋板の略水平姿勢を維持した押え蓋で、内容物の注出に伴って発生する不均一な負圧を内容物の上面全域に略均一に作用させ、流動性の悪いクリーム状内容物を最後まで円滑かつ確実に、手動ポンプから注出することができる。
【００１５】
請求項２記載の発明の手段は、請求項１記載の発明の構成に加え、傾斜防止筒を、シールリングの内筒片の内周面に接する傾斜防止筒片と、該傾斜防止筒片の上端に周接した外鍔部と、該外鍔部の外周端から垂下設したシールリングの上部外周面に接する組付片とから構成したこと、にある。
【００１６】
請求項２記載の発明にあっては、シールリングの内筒片の内周面に接する傾斜防止筒片と外鍔部とシールリングの上部外周面に内周面が接する組付片とから構成した傾斜防止筒を、軟質弾性材製のシールリングの上部に嵌着して組付けたため、注出容器の傾倒に伴ってシールリングが吸上げパイプ方向に傾倒した際に、最も大きな負荷のかかるシールリングの上部を、硬質材製の傾斜防止筒で保護した状態となり、軟質弾性材製のシールリングの形状変形を防止して、吸上げパイプに対する蓋板の略水平姿勢を安定に維持するとともに、吸上げパイプの外径よりも僅かに大きい値に設定した内径を有する傾斜防止筒片が吸上げパイプの外周面に当接して、シールリングを支持し、押え蓋全体の傾斜を確実に防止する。
【００１７】
請求項３記載の発明の手段は、請求項２記載の発明の構成に加え、傾斜防止筒の傾斜防止筒片を、シールリングの内筒片の内周面下部まで長片状に連設したこと、にある。
【００１８】
請求項３記載の発明にあっては、傾斜防止筒の傾斜防止筒片を、長片状に連設したため、比較的変形しやすい軟質弾性材製のシールリングの内筒片の略全域を硬質材製の長片状の傾斜防止筒片で保護することができ、シールリングの形状変形を防止して、シールリングに内周縁が密に組付く蓋板の吸上げパイプに対する略水平姿勢を安定に維持する。
【００１９】
なお、傾斜防止筒片は、下端をそのままシールリングの内筒片の内周面下端部まで連設した長筒状としてもよく、また、傾斜防止筒片の下端を部分的に内筒片の内周面下端部まで連設した複数の突条状の長片としてもよい。
【００２０】
請求項４記載の発明の手段は、請求項１、２または３記載の発明の構成に加え、
内筒片の縦方向中間部から外鍔状のフランジを周設したこと、該フランジの外周端から、内筒片との間に弾性変位用の間隙を設けて、蓋板の内周縁が密に組付く弾性筒片を垂下設したこと、該弾性筒片の下端部から外鍔状に蓋板を支持する底板を設けたこと、弾性筒片の外周面に、上方から蓋板を係止する係止突条を周設したこと、にある。
【００２１】
請求項４記載の発明にあっては、蓋板が内筒片からフランジを介して、弾性変位用の間隙を設けたシールリングの弾性筒片に密に組付くため、弾性筒片の弾圧性により、蓋板の外周縁が容器本体に近接した状態を維持する。また、容器本体が傾倒状態となって、蓋板の外周縁が容器本体に弾接した場合であっても、容器本体を起立した状態に戻すと、弾性筒片が弾性復帰し、再び、蓋板の外周縁が容器本体に近接した状態を安定に維持する。
【００２２】
請求項５記載の発明の手段は、請求項１、２，３または４記載の発明の構成に加え、内筒片の上端部に、外鍔状の摘み片を周設したこと、にある。
【００２３】
請求項５記載の発明にあっては、内筒片の上端部に外鍔状の摘み片を周設したため、内容物の注出にしたがって、シール片が吸い上げパイプに密摺接した状態で下降変位し、注出容器の底部に密着した押え蓋を、摘み片の把持して、簡単に容器本体の底部から取り外すことができる。
【００２４】
請求項６記載の発明の手段は、請求項６記載の発明の構成に加え、傾斜防止筒の組付片の内面下端部に、シールリングの摘み片に下方から係合する係合突条を周設したこと、にある。
【００２５】
請求項６記載の発明にあっては、傾斜防止筒の組付筒片の内周面下端部に、係合突条を設けたため、傾斜防止筒をシールリングに外嵌して不動に組付けることができ、シールリングの上端に嵌着している傾斜防止筒を把持した場合であっても、傾斜防止筒がシールリングから外れず、一体的に組付いた傾斜防止筒とシールリングと蓋板とを、簡単に容器本体の底部から取り外すことができる。
【００２６】
【発明の実施の形態】
以下、本発明の実施例を、図面を参照しながら説明する。
図１に示すように、容器本体１は、胴部２と底部３とから成る主体部１ａと、この胴部２の上端部外周に螺合する組付き筒４と肩部５と口部６とから成るヘッド部１ｂとから構成されている。
【００２７】
ヘッド部１ｂの口部６には、この口部６の外周に螺合する装着筒７を介して、縦型手動ポンプ１０が装着されており、ポンプ１０上端の押下げヘッド１１を上下動させることにより、下端に連結した吸上げパイプ１３を介してクリーム状内容物Ａを吸い上げ、押下げヘッド１１の注出ノズル１２から注出するようになっている。
【００２８】
押え蓋２０は、硬質材の合成樹脂等から成るリング板状の蓋板２１と、この蓋板２１の内周縁に密に組付けられる軟質弾性材であるポリエステル系エラストマー製のシールリング２２と、シールリング２２の上部に不動に組付けられる、ポリプロピレン樹脂若しくは低密度ポリエチレン樹脂等の硬質材製の傾斜防止筒３１とから構成されている。
【００２９】
図２及び図３は、押え蓋２０の第一の実施例を示し、図２は、押え蓋２０の一部縦断面図、図３は、一部を破断したシールリング２２と傾斜防止筒片３１の斜視図である。
【００３０】
図２及び図３に示すように、シールリング２２は、吸上げパイプ１３に緩く外嵌する円筒状の内筒片２３の内周面下部に、吸上げパイプ１３の外周面に弾力的に密摺接して、空気の下方への通過を防止する内鍔状のシール片２４を突周設している。
【００３１】
シールリング２２の内筒片２３の外周面の縦方向中間部には、外鍔状のフランジ２６を周設し、該フランジ２６の外周端から、内筒片２３との間に弾性変位用の間隙を設けて円筒状の弾性筒片２７を垂下設し、該弾性筒片２７の外周面下端部から外鍔状に底板２８を設け、弾性筒片２８の外周面の上部に、上方から蓋板２１を係止する係止突条２９を周設している。
【００３２】
シールリング２２は、蓋板２１の内周縁が、弾性筒片２７の外周面に密に組付くとともに、底板２８と係止突条２９で蓋板２１を係止し、蓋板２１とシールリング２２との組付き固定を達成している。
【００３３】
蓋板２１が、内筒片２３からフランジ２６を介して弾性変位用の間隙を設けた弾性筒片２７に組付き固定されているため、弾性筒片２７の弾圧性により、蓋板２１の外周縁が、容器本体１の胴部２の内面に近接した状態を維持したまま、押え蓋２０が下降変位する。
【００３４】
また、注出容器１が傾倒状態となった場合に、蓋板２１の外周縁が、容器本体１の胴部２の内面に弾接された場合であっても、注出容器１を起立させると、弾性筒片２７が弾性復帰し、再び、蓋板２１の外周縁が容器本体１の胴部２の内面に近接する良好な状態を確保する。
【００３５】
シールリング２２のシール片２４は、吸上げパイプ１３に弾性変形して密摺接し、中央側を上昇傾斜させた組付き姿勢となるため、内容物Ａの吸い上げに伴い、負圧が作用した際に、吸上げパイプ１３に対するシール片２４の圧接が強まり、これにより吸上げパイプ１３とシール片２４とのシール性が確保されて、負圧による空孔の発生を確実に防止することになる。
【００３６】
なお、中央側を上昇傾斜させたシール片２４の吸上げパイプ１３に対する組付き姿勢は、吸上げパイプ１３に組付いた押え蓋２０が下降変位することにより必然的に得られるものである。
【００３７】
シールリング２２は、押え蓋２０の速やかで正確な下降変位を実現するため、シール片２４のみが吸上げパイプ１３に密摺接し、内筒片２３が吸上げパイプ１３から所定距離離間して、緩く外嵌している。
【００３８】
シールリング２２に嵌着した傾斜防止筒３１は、シールリング２２の内筒片２３の内周面に接する傾斜防止筒片３２と、該傾斜防止筒片３２の上端に周設した外鍔部３３と、該外鍔部３３の外周端から垂下設した、シールリング２２の摘み片３０の外周面に内周面が接する組付片３４とから構成している。
【００３９】
傾斜防止筒片３２の内径は、吸上げパイプ１３の外径よりも僅かに大きい値となるように設定し、傾斜防止筒片３２が、シールリング２２の内筒片２３の内周面下端部まで連設した長筒状となるように形成している。
【００４０】
組付片３４の内周面下端部には、摘み片３０に下方から係合する係合突条３６を周設している。傾斜防止筒３１を、シールリング２２に嵌着すると、摘み片３０が係合突条３６を乗り越えて、係合突条３６が下方から摘み片３０に係合し、傾斜防止筒３１がシールリング２２に不動に組付く。
【００４１】
なお、長筒状の傾斜防止筒片２３をシールリング２２の内筒片２３に嵌着しやすいように、傾斜防止筒片３２の外周面下端部には、シールリング組付き用テーパ部３６を設けている。また、傾斜防止筒３１が不動に組付いたシールリング２２を吸上げパイプ１３に組付け易いように、傾斜防止筒片３２の内周面上端部には、吸上げパイプ１３組付き用テーパ部３７を設けている。
【００４２】
搬送途中の状況により、容器本体１が横倒しの状態となると、吸上げパイプ１３に弾力的に密摺接しているシール片２４のみでは、シールリング２２に緩く外嵌している内筒片２３を保持できず、シールリング２２が吸上げパイプ１３方向に傾くため、押え蓋２０全体が傾斜することになる。
【００４３】
容器本体１の傾倒状態に伴って、シールリング２２が吸上げパイプ１３方向の傾こうとすると、吸上げパイプ１３の外径よりも僅かに大きい値に設定された内径を有する長筒状の傾斜防止筒片３２が、吸上げパイプ１３の長手方向に沿って、吸上げパイプ１３の外周面に当接し、シールリング２２を支持するため、押え蓋２０全体の傾斜を防止できる。
【００４４】
また、硬質材製の長筒状の傾斜防止筒片３２が、内筒片２３の内面から軟質弾性材製のシールリング２２を保護して、変形しやすいシールリング２２の形状変形を防止し、シールリング２２に内周縁が密に組付いている蓋板２１の略水平姿勢を安定に維持する。
【００４５】
容器本体１が傾倒状態となっても、容器本体１内の押え蓋２０が傾斜しないため、粘度の高いクリーム状の内容物Aが、蓋板２１を越えて、押え蓋２０よりも容器本体１の上部に流動することはなく、吸上げパイプ１３に対する蓋板２１の略水平姿勢を安定に維持した押え蓋２０で、内容物Ａの吸い上げに伴って発生する不均一な負圧を内容物Ａの上面全域に略均一に作用させて、良好な注出動作を維持することができ、流動性の悪いクリーム状内容物Aを最後まで円滑かつ確実に、手動ポンプ１０から注出する。
【００４６】
容器本体１の内容物Aを最後まで円滑に注出すると、押え蓋２０は、吸上げパイプ１３の下降限まで下降変位し、容器本体１の底部３に密着する。容器本体１を再利用する際には、組付き筒４を胴部２の上端部から螺脱して、ヘッド部１ｂを主体部１ａから離間し、主体部１ａの底部３に密着している押え蓋２０の摘み片３０を把持して、簡単に押え蓋２０を底部３から取り外すことができる。
【００４７】
シールリング２２に嵌着した傾斜防止筒３１は、係合突条３５が摘み片３０に下方から係合し、シールリング２２に不動に組付いているため、組付片３４ごと摘み片３０を把持して、一体的に組付いた傾斜防止筒片３１とシールリング２２と蓋板２１とを、簡単に底部３から取り外すことができ、内容物Ａを再び注出容器に充填して再利用する際に、便利である。
【００４８】
図４は、本発明の第二の実施例を示し、押え蓋２０の一部縦断面図である。図４に示すように、傾斜防止筒３１の傾斜防止筒片３２を長筒状とせず、シールリング２２の内周面の少なくとも上部に接する短筒状としてもよい。
【００４９】
注出容器１の傾倒伴ってシールリング２２が吸上げパイプ１３方向に傾斜した場合に、もっとも大きな負荷のかかるシールリング２２の上部が、硬質材製の傾斜防止筒３１で安定に保護された状態となり、該傾斜防止筒３１で、シールリング２２の形状変形を防止して、吸上げパイプ１３に対する蓋板２１の略水平姿勢を安定に維持し、傾斜防止筒片３２が吸上げパイプ１３の外周面に当接して、シールリング２２を支持するため、押え蓋２０全体の傾斜が防止される。
【００５０】
図５は、傾斜防止筒３１の第三の実施例を示し、一部を破断した傾斜防止筒３１の斜視図である。図５に示すように、傾斜防止筒片３２は、傾斜防止筒片３２の下端部を部分的に、内筒片２３の内周面下端部まで連設した突条状の長片３２ａとしてもよい。
【００５１】
傾斜防止筒片３２の下端部を突条状の長片３２ａとした場合においても、突条状の長片３２ａが、内筒片２３の内周面に接して、軟質弾性材製のシールリング２２を保護するため、変形しやすいシールリング２２の形状を保持して、シールリング２２に内周縁が密に組付く蓋板２１の略水平姿勢を安定に維持し、押え蓋２０で、内容物Ａの吸い上げに伴って発生する不均一な負圧を内容物Ａの上面全域に略均一に作用させ、良好な注出動作を維持することができる。傾斜防止筒片３２の下端部を突条状の長片３２ａとすると、傾斜防止筒３１を形成する硬質材を減少することができる。
【００５２】

【００５３】
内容物の吸い上げに伴う不均一な負圧が、押え蓋に作用した場合であっても、硬質材製の傾斜防止筒が吸上げパイプの外周面に当接して、軟質弾性材製のシールリングを支持するため、吸上げパイプに対する蓋板の略水平姿勢を安定に維持した状態で、押え蓋の傾斜を確実に防止することができ、該押え蓋で、内容物の注出に伴って発生する不均一な負圧を内容物の上面全域に略均一に作用させ、流動性の悪いクリーム状内容物を最後まで円滑かつ確実に、手動ポンプから注出することができる。

【００５５】
請求項３記載の発明にあっては、傾斜防止筒の傾斜防止筒片を、長片状に連設したため、比較的変形しやすい軟質弾性材製のシールリングの内筒片を、硬質材製の長片状の傾斜防止筒片で保護して、シールリングの形状を安定に保持することができる。
【００５６】
請求項４記載の発明にあっては、蓋板が、弾性変位用の間隙を設けた弾性筒片に密に組付くため、弾性筒片の弾圧性により、粘度の高い内容物が蓋板を越えて、蓋板よりも上部に流動することなく、蓋板の外周縁が容器本体に近接した状態を安定に維持する。
【００５７】

BACKGROUND OF THE INVENTION
The present invention relates to a dispensing container for dispensing a creamy content having a relatively high viscosity using a manual pump.
[0002]
[Prior art]
As a conventional technique for this type of dispensing container that dispenses cream-like contents using a manual pump, a bottomed cylindrical container body has a suction opening toward the inner bottom of the container body. A pump mechanism connected to a suction pipe is provided, and is slidably inserted into the container body with respect to the suction pipe. The suction pipe is brought into close contact with the liquid level of the contents as the contents are sucked up. There is known one provided with a presser lid that moves along the head.
[0003]
Since the contents in the container body are cream-like substances with poor fluidity, the presser lid has a hole from the lower end where the suction opening of the suction pipe is located to the upper surface of the contents as it is sucked up. Is formed around the suction pipe, and as a result, it is intended to prevent the smooth dispensing of the contents from being hindered by the mixing of air that has passed through the air holes. By holding the upper surface of the contents with the presser lid, the negative pressure associated with the suction of the contents of the manual pump is applied uniformly to the entire contents. This prevents the formation of voids formed by acting on a part of the liquid and maintains a good content dispensing operation.
[0004]
In addition, if the content has a high viscosity, the negative pressure biased action time that accompanies the suction of the content is long, which may cause the presser lid itself to deform. Made of a hard material, the part (inner peripheral edge) that is in close contact with the suction pipe is made of a soft elastic material, and maintains a tightly slidable assembly with the suction pipe without deformation due to negative pressure I can do it.
[0005]
Japanese Patent Application Laid-Open No. 2000-219284 discloses a cylindrical lid that is tightly assembled to a ring plate-like hard material lid plate and an inner peripheral edge of the lid plate and loosely fits on a suction pipe. There is disclosed a pouring container constituted by a polyester elastomer seal ring having an inner collar-like seal piece provided at the lower end of the inner peripheral surface of the inner cylinder piece.
[0006]
In the above-described dispensing container, the seal piece provided on the inner cylinder piece of the seal ring is elastically slidably contacted with the outer peripheral surface of the suction pipe in a state where the central side is inclined upward, and negative pressure is applied. The cover plate that is attached to the inner cylinder piece of the seal ring and covers almost the entire upper surface of the contents is strengthened by strengthening the pressure contact of the seal piece against the suction pipe and reliably blocking the passage of air downward. Accommodates negative pressure that acts unevenly with the suction of an object without deformation, and presses the entire upper surface of the contents almost uniformly while the cover plate maintains a substantially horizontal posture, resulting in a creamy content with poor fluidity It ensures that things can be poured out smoothly and reliably.
[0007]
When the presser cover is displaced downward, the presser cover may tilt due to the non-uniform action of negative pressure. However, the presser cover part facing the suction pipe of the manual pump is only a polyester elastomer seal ring. Therefore, even if the cap is tilted, the presser lid is only elastically pressed against the suction pipe, and the presser lid is smoothly and reliably moved downward without being hooked.
[0008]
[Problems to be solved by the invention]
However, when the dispensing container filled with cream-like contents is tilted in the middle of transportation, etc., it is possible to prevent the presser lid from tilting with respect to the suction pipe only with the seal piece that is in close sliding contact with the suction pipe. First, the presser lid is inclined with respect to the suction pipe, and the gap between the lid plate and the inner wall of the container body becomes larger. From this gap, the cream-like contents with high viscosity pass over the lid plate and the upper part of the presser lid There is a problem of fluidity.
[0009]
Because the contents are creamy with poor fluidity, once the contents flow over the lid plate and above the presser lid, the contents will not be retained even if the tilted dispensing container is raised. There is a problem that the contents cannot be used up to the end while the contents remain on the upper part of the presser lid without being returned to the lower part while remaining on the upper part of the cover.
[0010]
In addition, the high-viscosity content that has flowed over the lid plate to the upper part of the presser lid does not return to the lower part even when the pouring container is raised, so a hole is generated between the presser lid and the content. The presser lid remains in an inclined state, and the tilted presser cover cannot press the entire upper surface of the contents substantially uniformly, so that the non-uniform negative pressure generated when the contents are sucked up is The problem arises that the smooth pouring of contents with poor fluidity is hindered.
[0011]
Therefore, the present invention was devised to solve the above-mentioned problems, and in the pouring container provided with a presser lid for the contents in the container body having a manual pump, the shape of the seal ring made of a soft elastic material An object of the present invention is to provide a pouring container that can smoothly and reliably pour out a creamy content having a large viscosity.

[0030]
As shown in FIGS. 2 and 3, the seal ring 22 is elastically sealed to the outer peripheral surface of the suction pipe 13 at the lower portion of the inner peripheral surface of the cylindrical inner cylinder piece 23 that is loosely fitted to the suction pipe 13. An inner collar-shaped seal piece 24 that protrudes in sliding contact and prevents the passage of air downward is provided.
[0031]
An outer flange-like flange 26 is provided around the outer peripheral surface of the inner cylindrical piece 23 of the seal ring 22, and elastic displacement is provided between the outer peripheral end of the flange 26 and the inner cylindrical piece 23. A cylindrical elastic cylinder piece 27 is provided with a gap, a bottom plate 28 is provided in an outer casing shape from the lower end portion of the outer peripheral surface of the elastic cylinder piece 27, and a lid is applied to the upper part of the outer peripheral surface of the elastic cylinder piece 28 from above. A locking ridge 29 for locking the plate 21 is provided around.
[0032]
The seal ring 22 has the inner peripheral edge of the cover plate 21 closely assembled to the outer peripheral surface of the elastic cylinder piece 27, and the cover plate 21 is locked by the bottom plate 28 and the locking protrusions 29. The combination fixing with 22 is achieved.
[0033]
Since the lid plate 21 is assembled and fixed from the inner cylinder piece 23 through the flange 26 to the elastic cylinder piece 27 provided with a gap for elastic displacement, the elastic plate piece 27 is elastically attached to the outside of the lid plate 21. The presser lid 20 is displaced downward while maintaining the state in which the peripheral edge is close to the inner surface of the body portion 2 of the container body 1.
[0034]
Further, when the pouring container 1 is tilted, the pouring container 1 is erected even when the outer peripheral edge of the cover plate 21 is elastically contacted with the inner surface of the body portion 2 of the container main body 1. Then, the elastic cylinder piece 27 is elastically restored, and again, the outer peripheral edge of the lid plate 21 is ensured to be in a good state close to the inner surface of the body portion 2 of the container body 1.
[0035]
Since the seal piece 24 of the seal ring 22 is elastically deformed and brought into close sliding contact with the suction pipe 13 and has an assembled posture in which the center side is inclined upward, when the negative pressure is applied as the contents A are sucked up. In addition, the pressure contact of the seal piece 24 against the suction pipe 13 is strengthened, whereby the sealing performance between the suction pipe 13 and the seal piece 24 is secured, and the generation of holes due to negative pressure is surely prevented.
[0036]
The assembly posture of the seal piece 24 whose center side is inclined upward with respect to the suction pipe 13 is inevitably obtained when the presser lid 20 assembled to the suction pipe 13 is displaced downward.
[0037]
In order for the seal ring 22 to realize a quick and accurate downward displacement of the presser lid 20, only the seal piece 24 is in close sliding contact with the suction pipe 13, and the inner cylinder piece 23 is separated from the suction pipe 13 by a predetermined distance, Loosely fitted.
[0038]
The inclination prevention cylinder 31 fitted to the seal ring 22 includes an inclination prevention cylinder piece 32 in contact with the inner peripheral surface of the inner cylinder piece 23 of the seal ring 22 and an outer flange portion 33 provided around the upper end of the inclination prevention cylinder piece 32. And an assembly piece 34 that is suspended from the outer peripheral end of the outer collar portion 33 and that is in contact with the outer peripheral surface of the knob 30 of the seal ring 22.
[0039]
The inner diameter of the inclination prevention cylinder piece 32 is set to be slightly larger than the outer diameter of the suction pipe 13, and the inclination prevention cylinder piece 32 is a lower end portion of the inner peripheral surface of the inner cylinder piece 23 of the seal ring 22. It forms so that it may become the long cylinder shape continuously provided.
[0040]
At the lower end portion of the inner peripheral surface of the assembly piece 34, an engagement protrusion 36 that engages with the knob 30 from below is provided. When the tilt prevention cylinder 31 is fitted to the seal ring 22, the knob piece 30 gets over the engagement protrusion 36, the engagement protrusion 36 engages with the knob piece 30 from below, and the inclination prevention cylinder 31 becomes the seal ring. Assemble to No.22.
[0041]
In order to easily fit the long cylindrical anti-tilt cylinder piece 23 to the inner cylinder piece 23 of the seal ring 22, a taper portion 36 with a seal ring assembly is provided at the lower end of the outer peripheral surface of the anti-tilt cylinder piece 32. Provided. Further, in order to make it easy to assemble the seal ring 22 in which the inclination prevention cylinder 31 is fixedly attached to the suction pipe 13, a taper portion for attachment of the suction pipe 13 is provided at the upper end of the inner peripheral surface of the inclination prevention cylinder piece 32. 37 is provided.
[0042]
When the container body 1 is in a laid-down state due to the situation during the conveyance, the inner cylinder piece 23 that is loosely fitted to the seal ring 22 with only the seal piece 24 that is elastically slidably in contact with the suction pipe 13 is removed. Since it cannot hold | maintain and the seal ring 22 inclines in the suction pipe 13 direction, the presser lid 20 whole inclines.
[0043]
When the seal ring 22 is inclined in the direction of the suction pipe 13 with the tilted state of the container body 1, the long cylindrical inclination having an inner diameter set to a value slightly larger than the outer diameter of the suction pipe 13. Since the prevention cylinder piece 32 contacts the outer peripheral surface of the suction pipe 13 along the longitudinal direction of the suction pipe 13 and supports the seal ring 22, the entire presser lid 20 can be prevented from being inclined.
[0044]
Further, the long cylindrical anti-tilt cylinder piece 32 made of a hard material protects the seal ring 22 made of a soft elastic material from the inner surface of the inner cylinder piece 23 and prevents deformation of the seal ring 22 that is easily deformed, The substantially horizontal posture of the cover plate 21 whose inner peripheral edge is closely assembled to the seal ring 22 is stably maintained.
[0045]
Even when the container main body 1 is tilted, the presser lid 20 in the container main body 1 does not tilt, so that the cream-like content A having a high viscosity exceeds the cover plate 21 and is higher than the presser lid 20 in the container main body 1. The presser lid 20 that stably maintains the substantially horizontal posture of the lid plate 21 with respect to the suction pipe 13 and does not flow to the upper part of the suction pipe 13, and generates a non-uniform negative pressure generated as the contents A are sucked up. It can be made to act substantially uniformly on the entire upper surface of the liquid and maintain a good dispensing operation, and the cream-like content A having poor fluidity is smoothly and reliably dispensed from the manual pump 10 to the end.
[0046]
When the content A of the container body 1 is smoothly poured out to the end, the presser lid 20 is displaced downward to the lower limit of the suction pipe 13 and is in close contact with the bottom 3 of the container body 1. When the container main body 1 is reused, the presser is attached to the bottom portion 3 of the main body 1a by unscrewing the assembled cylinder 4 from the upper end of the body 2 and separating the head 1b from the main body 1a. The presser lid 20 can be easily detached from the bottom portion 3 by gripping the knob 30 of the lid 20.
[0047]
The anti-tilt cylinder 31 fitted to the seal ring 22 has the engagement protrusion 35 engaged with the knob 30 from below and is fixedly attached to the seal ring 22. The anti-tilt cylinder piece 31, the seal ring 22, and the cover plate 21 that are gripped and assembled together can be easily removed from the bottom 3, and the contents A are filled again into the dispensing container and reused. It is convenient to do.
[0048]
FIG. 4 shows a second embodiment of the present invention and is a partial longitudinal sectional view of the presser lid 20. As shown in FIG. 4, the anti-tilt cylinder piece 32 of the anti-tilt cylinder 31 may not be a long cylinder, but may be a short cylinder that is in contact with at least the upper part of the inner peripheral surface of the seal ring 22.
[0049]
When the seal ring 22 is inclined toward the suction pipe 13 as the dispensing container 1 is tilted, the upper portion of the seal ring 22 to which the largest load is applied is stably protected by the anti-tilt cylinder 31 made of hard material. Thus, the inclination prevention cylinder 31 prevents the seal ring 22 from being deformed and stably maintains the substantially horizontal posture of the cover plate 21 with respect to the suction pipe 13, and the inclination prevention cylinder piece 32 is provided on the outer periphery of the suction pipe 13. Since the seal ring 22 is supported in contact with the surface, the entire presser lid 20 is prevented from being inclined.
[0050]
FIG. 5 is a perspective view of the tilt preventing cylinder 31 showing a third embodiment of the tilt preventing cylinder 31 with a part thereof broken. As shown in FIG. 5, the anti-tilt cylinder piece 32 may be a long strip 32 a having a ridge shape in which the lower end portion of the anti-tilt cylinder piece 32 is partially connected to the lower end portion of the inner peripheral surface of the inner cylinder piece 23. Good.
[0051]
Even in the case where the lower end portion of the inclination preventing cylinder piece 32 is a ridge-like long piece 32a, the ridge-like long piece 32a is in contact with the inner peripheral surface of the inner cylinder piece 23 and is made of a soft elastic seal ring. In order to protect 22, the shape of the easily deformable seal ring 22 is maintained, and the substantially horizontal posture of the cover plate 21 whose inner peripheral edge is closely assembled to the seal ring 22 is stably maintained. A non-uniform negative pressure generated along with the suction of A can be applied to the entire upper surface of the content A substantially uniformly, and a good dispensing operation can be maintained. If the lower end portion of the inclination prevention cylinder piece 32 is a long strip 32a, the hard material forming the inclination prevention cylinder 31 can be reduced.
[0052]
