Description

【０００１】
【発明の属する技術分野】
本発明は、内容物の注出が可能な注出容器に関し、特に、定形に成形された外層と、該外層に剥離可能に積層した内層とから構成される合成樹脂製の容器本体と、この容器本体の底部に外嵌組付けされるベースカップとの組合わせ構造とから成る注出容器に関する。
【０００２】
【従来の技術】
内容物を容器から注出する際には、容器の胴部を指で押圧して、内容物を注出したり、容器の口部に設けたポンプ等を利用して、内容物を注出する容器が多く用いられている。
【０００３】
内容物を注出する容器としては、外層とこの外層に剥離自在に積層された内層とからなり、内容物が減少した分、内層が外層から剥離しながら萎み変形し、外層と内層との間隙に外部空気を導入する積層容器がある。
【０００４】
【発明が解決しようとする課題】
しかしながら、外層から内層が剥離可能な積層構造の容器にあっては、内容物の減少に伴って、内層が減容変形するため、流路が減容変形した内層に阻まれて、内容物が流出しにくくなるとともに、内容物の減少に伴って、外層を押圧した場合であっても、減容変形した内層が加圧されにくくなり、内容物の円滑な注出操作が妨げられる、と云う問題があった。
【０００５】
内容物の円滑な注出操作が妨げられると、内容物の残量が多くなり、容器内の内容物を最後まで使い切ることができない、と云う問題もあった。
【０００６】
また、内層の減容変形に伴って、容器本体の内部が減圧状態となるため、外層が元の状態まで復元せず、外観上の体裁が悪い、と云う問題がある。
【０００７】
また、外層と内層との間に空気を導入する通気孔を形成するためには、成形機の設計変更等が必要となって製造コストが高騰したり、通気孔を形成するために面倒な後加工操作が必要となって、製品完成までに要する処理工数が多くなり、製造加工が面倒になる、と云う問題があった。
【０００８】
そこで、本発明は上記した従来の技術の問題点を解消すべく創案されたものであり、積層構造容器において容易に実現可能な逆止弁機構の創出を技術的課題とし、もって高い生産性を維持し、操作性の優れた外観上良好な注出容器を提供することを目的とする。
【０００９】
【課題を解決するための手段】
上記技術的課題を解決するための本発明のうち、請求項１記載の発明の手段は、
内容物の注出容器であること、
外層の内面に該外層から剥離可能な内層を積層し、上部に内容物の流路を形成する本体口部を設け、有底筒形状の底部を構成する外層の一部に、外層と内層との間に外部の空気を吸入する空気導入部を開設した容器本体を有すること、
容器本体の底部に外嵌組付きするベースカップを有すること、
該ベースカップに組付け固定する、容器本体の底部の空気導入部に外部の空気を導入し、導入した空気の逆流を防止する第１逆止弁体を有すること、
にある。
【００１０】
請求項１記載の手段にあっては、容器本体から内容物を注出すると、内容物の注出によって、内層が外層から剥離して減容変形し、外層と内層との間に隙間が形成されるため、第１逆止弁体が開いて、外層と内層との間に外部の空気が導入されることになる。
【００１１】
内層と外層との間が空気で満たされると、第１逆止弁体の機能により、空気導入部と外部の空気との連通を遮断して、内層と外層との間に導入した空気の逆流を防止し、内層と外層との間に空気が満たされた状態を維持し、外観上の良好な体裁を維持する。
【００１２】
請求項２記載の発明は、請求項１記載の発明において、容器本体をスクイズ変形可能としたこと、
容器本体の本体口部に、容器本体から流出した内容物の逆流および外部の空気の流入を不能に流路を開閉する第２逆止弁体を設けたこと、にある。
【００１３】
請求項２記載の発明にあっては、スクイズ可能な容器本体の胴部を押圧すると、流路を閉塞していた第２逆止弁体が開放し、内容物を注出する。容器本体の押圧を解除すると、内容物の注出が止まり、外層が弾性回復力により元の形に復元し始め、第２逆止弁体の機能により、第２逆止弁体が流路を閉塞し、押圧状態の解除により減圧状態となった容器本体内部への内容物の逆流および外部の空気の進入を防ぐことができる。
【００１４】
この際、内層は減容変形した状態を保持したままであるので、元の形に復元しようとする外層と、減容変形状態を保持する内層と隙間が減圧状態となり、第１逆止弁体が開放し、容器本体の底部の空気導入部から外層と内層との間に外部の空気を導入し、導入した空気及び外層の弾性復元力により、素早く、外層を元の形状まで復元する。
【００１５】
外層が元の状態に復元した後、再び容器本体の胴部を押圧すると、外層と内層との間が加圧状態となり、第１逆止弁体の機能により、空気導入部と外部の空気との連通を遮断して、内層と外層との間に導入した空気の逆流を防止する。このため、容器本体の胴部を押圧した際に、外層と内層との間に存在する空気を介して、減容変形している内層内の内容物を確実に加圧することができ、再び第２逆止弁体が本体口部を開放して、注出口から内容物を注出する。
【００１６】
容器本体の底部に空気導入部を開設した場合であっても、有底円筒状のベースカップを、容器本体の底部に外嵌しているため、ベースカップで容器本体の底部を補強し、注出容器の底部分の形態を安定に保持する。
【００１７】
請求項３記載の発明の手段は、請求項１または２記載の発明において、容器本体の底部外周面に、凹溝を周設し、該凹溝にＯリングを設けたこと、該Ｏリングを介して、ベースカップを容器本体の底部に密に外嵌したこと、を加えたものである。
【００１８】
請求項３記載の発明にあっては、容器本体の底部に、ベースカップの筒壁を密に外嵌組付けする手段として、容器本体の底部にＯリングを設けているため、容器本体の底部とベースカップの隙間から、容器本体の外層と内層の間に導入した空気を漏出することを防止し、確実に空気導入部から減容変形した内層と外層との間に外部の空気を流入して、素早く外層を元の形状に復元することができる。
【００１９】
容器本体をスクイズ変形した際には、容器本体の底部とベースカップの隙間から空気を漏出することなく、内層と外層の間に存在する空気を介して、確実に外層の押圧によって、内容物を加圧することができる。
【００２０】
請求項４記載の発明の手段は、請求項１、２または３記載の発明において、容器本体の底部に密に外嵌組付きするベースカップを有底円筒状としたこと、
ベースカップのカップ底部に、外部の空気を導入する通気孔を設けたこと、
第１逆止弁体を、ベースカップに組付き固定する固定枠と、外部の空気を導入するスリットを設けた固定枠の開口域を覆うスリット板とから構成したこと、にある。
【００２１】
請求項４記載の発明にあっては、カップ底部に通気孔を設け、容器本体の底部に密に外嵌組付きする有底円筒状のベースカップに、固定枠と、スリットを設けたスリット板とから成る第１逆止弁体を設けたため、容器本体の底部をベースカップで安定に補強するとともに、第１逆止弁体を簡単な構造として、製造加工を容易とし、第１逆止弁体をベースカップに簡単に組付け固定することができる。
【００２２】
請求項５記載の発明の手段は、請求項１、２または３記載の発明において、容器本体の底部に密に外嵌組付きするベースカップを有底円筒状としたこと、
ベースカップのカップ底部に、外気を導入する外気孔を設けたこと、

【００２３】
請求項５記載の発明にあっては、容器本体の底部に密に外嵌組付きするベースカップを有底円筒状として、注出容器の底部をベースカップで安定に補強するとともに、第２逆止弁体が、連結片を基端として揺動し、通気孔を開閉して内層と外層との間に外部の空気を導入し、導入した空気の逆流を防止する。
【００２４】
請求項６記載の発明の手段は、請求項１、３、４または５記載の発明において、第１逆止弁体に、容器本体の底部に外嵌するとともに、ベースカップの筒壁に内嵌し、ベースカップを、容器本体の底部に密に外嵌組付けするパッキン片を、弾性軟質材で一体成形したことを、加えたものである。
【００２５】
請求項６記載の発明にあっては、第１逆止弁体にパッキン片を弾性軟質材で一体成形したため、パッキン片が、容器本体の底部とベースカップの筒壁とでパッキン片が狭持された状態となり、容器本体の底部とベースカップの隙間から、容器本体の外層と内層の間に導入した空気を漏出することを防止し、確実に空気導入部から減容変形した内層と外層との間に外部の空気を流入して、素早く外層を元の形状に復元する。
【００２６】
本願請求項７記載の発明の手段は、請求項１、２、４、５または６記載の発明において、容器本体の底部の底板壁下面に、パーティングラインに沿って、外層に形成された食い切り部を開口して、空気導入部としたこと、を加えたものである。
【００２７】
請求項７記載の発明にあっては、相溶性の殆ど無い外層パリソンと内層パリソンとを共押し出しした積層パリソンを、金型のピンチオフ部で押し潰し成形される食い切り部に、容易に発生する底割れをそのまま空気導入部として用いることができ、面倒な後加工操作を必要とすることなく、空気導入部を外層に形成することができる。
【００２８】
底部のパーティングラインに沿って形成された食い切り部を開口して空気導入部とした場合、容器本体の底部が底割れした状態となるが、本発明にあっては、有底円筒状のベースキャップを、容器本体の底部に外嵌し、容器本体の底部を補強し、例えば、座機能が低下する等の不都合を発生することなく、注出容器の底部分の形態を安定に保持する。
【００２９】
請求項８記載の発明の手段は、請求項７記載の発明において、容器本体の底板壁に対して、パーティングラインに沿った押圧力を作用させる押圧機能部を、ベースカップに設けたこと、にある。
【００３０】
請求項８記載の発明にあっては、ベースカップの押圧機能部によって、容器本体の底部にベースカップを外嵌組付けすると、容器本体の底板壁を構成する外層の食い切り部に、パーティングラインに沿って底割れ状のスリットを開口させることができ、この開口したスリットをそのまま、空気導入部として用いることができる。
【００３１】
請求項９記載の発明の手段は、請求項１、２、３、４、５、６、７または８記載の発明において、有頂円筒状の嵌入筒片を有し、該嵌入筒片の頂壁の中央部に流路を構成する開口筒片を垂下設し、該開口筒片に、該開口筒片との間に内容液が流通する通路部を形成する棒体を設け、頂壁の周縁端部にシール筒片を起立設し、嵌入筒片を容器本体の本体口部に密嵌入して、容器本体に組付き固定する栓体を設けたこと、
栓体を介して、シール筒片に注出部材を密嵌入して、注出部材を容器本体の本体口部に組付き固定したこと、
にある。
【００３２】
請求項９記載の発明にあっては、栓体との間に内容物を流通する通路部を形成する棒体を設けた栓体を介して、注出部材を容器本体の本体口部に組付け固定したため、内容物を注出した際に、外層から剥離した内層が、強い吸引力が働く開口筒片に引き付けられて開口部分を塞いでしまうの防止し、内容物の減少にしたがって、内層の萎み変形が進行しても、内容物の流路を確実に保持して、最後まで内容物を注出することができる。
【００３３】
請求項１０記載の発明の手段は、請求項９記載の発明において、第２逆止弁体を、流路を構成する部材に組付き固定するリング片と、該リング片と連結片を介して、該連結片を基端として、揺動可能に栓体の開口筒片の開口を塞ぐ開閉弁とから構成したこと、にある。
【００３４】
請求項１０記載の発明にあっては、容器本体の胴部の押圧によって、内層内の内容物が確実に加圧され、容器本体の本体口部を塞いでいる開閉弁が開放して、内容液を注出口から注出させることができるとともに、容器本体の胴部の押圧の停止による内層内の減圧によって、開閉弁が容器本体の本体口部を閉塞し、外部の空気の内層内への進入を確実に防止する。
【００３５】
請求項１１記載の発明の手段は、請求項１、２、３、４、５、６、７、８または９記載の発明において、容器本体の本体口部に、上端に内容物を滴下する注出口を有し、本体口部から連続して流路を構成する滴下筒片を有する注出部材を設けたこと、にある。
【００３６】
請求項１１記載の発明にあっては、内容物を液滴状にも滴下することができるため、目薬等の容器として用いることができる。
【００３７】

【００３８】
請求項１２記載の発明にあっては、容器本体の内部が加圧状態となると、組付き筒の先端部のスリット開口部が開口し、内容物を注出することができ、また、容器本体の内部が減圧状態となると、スリット開口部が閉塞し、内容物の容器本体内への逆流を防止し、外部の空気の進入を阻止する逆止弁を簡単に注出部材に設けることができる。
【００３９】
請求項１３記載の発明の手段は、請求項１２記載の発明において、内容物を目薬容器としたこと、にある。
【００４０】
請求項１３記載の発明にあっては、小さい容器であっても第１逆止弁体の機能により、容器本体の外層が素早く元の形状に復元するため、操作性が良く、第２逆止弁体の機能により外部の空気等が内部に進入することがないため、衛生性に優れ、目薬用の容器として最適である。
【００４１】
請求項１４記載の発明にあっては、請求項１、２、３、４、５、６、７、８、９、１０、１１、１２または１３記載の発明において、容器本体の本体口部に、被対象物に対して内容物を塗布する塗布体を設けたこと、にある。
【００４２】
請求項１４記載の発明にあっては、容器本体の胴部の押圧によって、注出口から注出された内容物を、塗布体から、直接、被対象物に塗布することができる。
【００４３】
【発明の実施の形態】
以下、本発明の実施の形態について図面を参照にしながら説明する。
図１は、本発明における注出容器の一実施例の構造を示すものである。注出容器は、容器本体１、容器本体１の本体口部６に組付けた注出部材１４、注出部材１４内部に組付けた第１逆止弁体３０であるスリット弁、容器本体１の底部５に密に外嵌組付けしたベースカップ４０、該ベースカップ４０内に嵌入固定した第２逆止弁体５０と、から構成している。なお、容器本体１及び注出部材１４には、オーバーキャップ６０を被嵌している。
【００４４】
容器本体１は、押圧による弾性変形およびこの変形の回復が可能な外層２と、この外層２に対して相溶性の低い合成樹脂で、萎み変形自在で剥離可能な内層３とが積層された積層構造を有しており、胴部４の上部に肩部５を介して短円筒状の本体口部６を設けている。
【００４５】
容器本体１の本体口部６には、容器本体１内の内容物である目薬液を液滴状に滴下する滴下筒である注出部材１４を組付け固定している。注出部材１４は、本体口部６に密嵌入する組付き筒片１５と、該組付き筒片１５から周設した本体口部６の上端部を密閉するフランジ１６と、該フランジ１６から上方に徐々に縮径するように周立設し、本体口部６と連通して内容物の流路１８を形成する滴下筒片１７と、該滴下筒片１７の上端に開口した内容物を液滴状の注出する注出口１７ａとを設けている。
【００４６】
注出部材１４の流路１８には、第１逆止弁体３０を設けている。図２に示すように、第１逆止弁体３０は、注出部材１４の流路１８に組付き固定する組付き筒３１と、該組付き筒３１の先端部に設けたスリット開口部３１ａを設けて構成した、スリット弁である。
【００４７】
第１逆止弁体３０は、内容物の逆流及び外気の流入を不能とする逆止弁としての機能を有する。すなわち、外層２の押圧によって、内層３内が加圧状態となると、スリット開口部３１ａを形成している切片部分が、容器本体１内部の圧力により開口し、内容物をスリット開口部３１ａを通じて、注出口１７ａから液滴状に注出する。外層２の押圧が解除されて、内層３内が減圧状態となると、第１逆止弁体３０の機能によって、組付き筒３１の有頂膨出状の先端部に形成されたスリット開口部３１ａの切片部分が閉塞し、外部の空気の内層３内への進入を不能にする。
【００４８】
容器本体１の胴部４の下端部には、段部７を介して、窪み状の係合部８を周設し、係合部８から縮径形成された有底筒形状の底部９を連設している。この底部９の外層２に、外部の空気を内層３と外層２との間に流入する空気導入部１２を開口している。
【００４９】
容器本体１の底部９に外嵌した有底円筒状のベースカップ４０は、底部９に外嵌する筒壁４１と、外部の空気の流入路となる通気孔４４を設けたカップ底部４３とから成っている。筒壁４１の内周面上部には、容器本体１の底部の係合部８と係合する係止突条４２を設け、筒壁４１を、容器本体１の底部９に外嵌すると、係合部８と係止突条４２が係合して、筒壁４１の上端が、底部９の段部７に当接する構成となっている。
【００５０】
図３は、図１の横断面Ｘ−Ｘ矢視図であり、ベースカップ４０の筒壁４１を容器本体１の底部９に外嵌した底面図である。容器本体１の底部９は、容器本体１の底面を構成する底板壁１０の中央部に、内層と外層のパリソンをシールした食い切り部１１を開口した空気導入部１２を形成している。
【００５１】
空気導入部１２は、パーティングラインＰの延長上から圧接して、食い切り部１１をスリット開口することにより形成する。ベースカップ４０の筒壁４１に押圧機能部４５を設け、底部９に筒壁４１を外嵌すると略同時に、空気導入部１２を開口することも可能である。
【００５２】
すなわち、筒壁４１には、パーティングラインＰ上の寸法が、パーティングラインＰと直行する寸法よりも長径となっている容器本体１の楕円形状の底板壁１０に対して、底板壁１０のパーティングラインＰ上の長径よりも短径の真円筒形状とした押圧機能部４５を設けている。
【００５３】
容器本体１の底部９には、底板壁１０に連設して、パーティングラインＰに沿って、内層３と外層２とシールした食い切り部１１が、突条状に形成されている（図４（ａ）参照）。
【００５４】
容器本体１の底部９に押圧機能部４５を設けた筒壁４１を強引に外嵌組付けすると、押圧機能部４５が、パーティングラインＰに沿って食い切り部１１を押圧し、食い切り部１１にスリットを開口する（図４（ｂ）参照）。この開口したスリットを、空気導入部１２として用いる。
【００５５】
ベースカップ４０には、胴部４の押圧解除時には、通気孔４４を開放して、外部の空気を空気導入部１２から外層２と内層３との間に流入するとともに、胴部４の押圧時には、通気孔４４を閉塞して、流入した空気の逆流を防止する第２逆止弁体５０を設けている。
【００５６】
図５は、第２逆止弁体５０の実施例を示す平面図である。第２逆止弁体５０は、ベースカップ４０の筒壁４１に密嵌入して組付くリング状のリング片５１と、該リング片５１と連結片５２を介して、円盤状の開閉弁５３を連設している。開閉弁５３は、連結片５２を基端として上下方向への揺動が可能であり、逆止弁として機能する。
【００５７】
図５に示す構造の第２逆止弁体５０のみならず、図６に示すように、第２逆止弁体５０は、ベースカップ４０の筒壁４１の下端に組付き固定する固定枠５６と、該固定枠５６の開口を閉塞するスリット板５８に、十字状のスリット５７を形成したスリット弁体であっても良い。また、上述の構造に限らず、逆止弁としての機能を果たす各種の構造であればよい。
【００５８】
図７は、容器本体１の胴部４をスクイズ変形した際の注出容器の動作状態を示す図である。図７に示すように、胴部４を押圧すると、外層２から内層３が剥離して、内層３内が加圧状態となり、スリット弁である第１逆止弁体３０のスリット開口部３１ａが開口し、内容物である目薬液を注出口１７ａから液滴状に注出する。
【００５９】
胴部４の押圧が解除されると、加圧状態であった内層３は、減圧状態となり、外部の空気を吸引するように作用するが、この際に、第１逆止弁体３０の機能により、スリット開口部３１ａが閉塞するため、外部の空気を内層３内に吸引せず、内容物の逆流を防止する。
【００６０】
このため、胴部４の押圧を解除すると、外層２は、自己形状保持能力により、元の形状に弾性復元するが、外層２から剥離した内層３は、外部の空気を吸引せず、萎み状に減容変形したままとなり、外層２と内層３との間に隙間が形成される（図８（ａ）参照）。
【００６１】
外層２と内層３との間に隙間が形成されると、外層２と内層３との間が減圧状態となるため、第２逆止弁体５０の開閉弁５３が連結片５２を基端として底部９方向に揺動し、ベースカップ４０の通気孔４４が開放され、この通気孔４４から外部の空気を空気導入部１２に導入し、外層２と内層３との間に外気を流入する（図８（ｂ）参照）。
【００６２】
再び、容器本体１の胴部４を押圧すると、外層２と内層３との間が加圧状態となるため、第２逆止弁体５０の機能により、通気孔４４が開閉弁５３で閉塞され、空気導入部１２と外気の流通を遮断し、外層２と内層３との間に導入された空気の逆流を防止する。
【００６３】
このため、外層２の押圧により、外層２と内層３との間に存在する空気を介して、萎み変形した内層３内の内容液が確実に加圧され、再び第１逆止弁体３０のスリット開口部３１ａが開口して、滴下口３１ａから内容物を注出する。
【００６４】
図９は、本発明の注出容器の第二実施例を示し、容器本体１の底部９に拡大した段部７を設け、底部９に外嵌するベースカップ４０の筒壁４１の外周に、段部７の周端縁を下方から支持する皿状壁４６を、カップ底部４３から起立設している。
【００６５】
容器本体１の底部９は、ベースカップ４０の筒壁４１及び皿状壁４６で二重に覆われた状態となっているため、ベースカップ４０の外殻体としての補強機能がより向上し、容器本体１の底部９が機械的に安定し、底部９が座屈する等の不都合を生じない。
【００６６】
図１０は、本発明の注出容器の第三実施例を示す一部断面図を含む図である。図１０に示すように、容器本体１の口部６には、容器本体１内の縦方向略中間位置まで延出する棒体２４を設けた栓体２０を組付き固定している。なお、棒体２４の長さは、容器本体１内の縦方向中間位置に限定するものではなく、開口筒片２３との間に内容物を流通する通路部を有していれば、棒体２４の下端部が栓体２０近傍の長さとなるものであっても、棒体２４の下端部が底部９まで到達しているものであってもよい。
【００６７】
栓体２０は、容器本体１の口部６に嵌入して、栓体２０を組付き固定する有頂円筒状の嵌入筒片２１を有し、嵌入筒片２１の頂壁２２の中央部分に、開口筒片２３を垂下設し、該開口筒片２３に、該開口筒片２３との間に内容液が流通する流路を形成する端面十字状に交叉した棒体２４を設け（図１１参照）、頂壁２２の周端縁からシール筒片２５を起立設している。棒体２４は、端面十字状のみならず、開口筒片２３との間に通路部を形成することが可能であれば、先端がストレートなものであってもよく、そのほか、端面王字状のものであってもよく、棒体２４の形状は問わない。
【００６８】
注出部材１４は、栓体１１のシール筒片２５内に組付き筒片１５を嵌入して、密に組付き固定する。棒体２４は、内容物の減少に伴い、内層３の撓み変形が進行した場合であっても、内容物の流出する流路１８を確実に保持する。
【００６９】
栓体２０のシール筒片２５の内部には、シール筒片２５内に密に嵌入組付きするリング片３２と、該リング片３２に連結片３３を介して、揺動可能に栓体２０の開口筒片２３を閉塞する開閉弁３４とからなる第２逆止弁体３０を設けている。
【００７０】
また、ベースカップ４０内には、容器本体１の底板壁１０に上端が当接する短円筒状のリング片５１と、該リング片５１から連結片５２を介して、該連結片５２を基端として揺動可能に連結されている開閉弁５３と、リング片５１の上端から外鍔片５４を介して、起立設したパッキン片５５とを、弾性軟質材で一体成形した第２逆止弁体５０を設けている。
【００７１】
パッキン片５５は、容器本体１の底部９に外嵌するとともに、ベースカップ４０の筒壁４１に内嵌し、軟質弾性材製のパッキン片５５が底部９と筒壁４１とで狭持された状態となるため、外気を底部９と筒壁４１との間から進入せず、また、通気孔４４から導入した空気を外部に漏出しない。
【００７２】
すなわち、第２逆止弁体５０の逆止弁機能により、開閉弁５３が通気孔４４を開放して、外気を空気導入部１２に導入する際に、通気孔４４から導入した外気を底部９と筒壁４１との間から外部に漏出することなく、減容変形した内層３と外層２との間に確実に外気を導入することができる（図１２参照）。
【００７３】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pouring container capable of pouring out contents, and in particular, a synthetic resin container main body composed of an outer layer formed into a fixed shape and an inner layer releasably laminated on the outer layer, And a combination structure with a base cup externally fitted to the bottom of the container body.
[0002]
[Prior art]
When pouring out the contents from the container, press the body of the container with a finger to pour out the contents or use a pump provided at the mouth of the container to pour out the contents. Containers are often used.
[0003]
The container for discharging the contents is composed of an outer layer and an inner layer that is releasably laminated on the outer layer.As the content decreases, the inner layer peels and deforms while peeling off from the outer layer. There are laminated containers that introduce external air into the gap.
[0004]
[Problems to be solved by the invention]
However, in the case of a container having a laminated structure in which the inner layer can be peeled from the outer layer, the inner layer is reduced in volume as the content is reduced, so that the flow path is blocked by the inner layer having reduced volume and the content is reduced. It is said that it is difficult to flow out, and even when the outer layer is pressed with the decrease in the content, the volume-reduced inner layer is less likely to be pressed, which hinders the smooth pouring operation of the content. There was a problem.
[0005]
If the smooth dispensing operation of the contents is hindered, there is a problem that the remaining amount of the contents increases and the contents in the container cannot be used up to the end.
[0006]
Further, since the inside of the container body is decompressed with the volume reduction deformation of the inner layer, the outer layer is not restored to the original state, and the appearance is poor.
[0007]
In addition, in order to form a ventilation hole for introducing air between the outer layer and the inner layer, it is necessary to change the design of the molding machine, etc., so that the manufacturing cost rises, and after forming the ventilation hole, it is troublesome to form the ventilation hole. There is a problem in that a processing operation is required, the number of processing steps required to complete the product increases, and the manufacturing processing becomes complicated.
[0008]
Therefore, the present invention has been made in order to solve the above-mentioned problems of the conventional technology, and a technical problem is to create a check valve mechanism that can be easily realized in a laminated structure container, thereby achieving high productivity. An object of the present invention is to provide a pour container that is maintained and has excellent operability and is excellent in appearance.
