Description

【０００１】
【発明の属する技術分野】
本発明は、液状、ゼリー状等の内容物を充填し、飲料用や医療用などに使用する注出口装置とそれを備えた注出口装置付袋状容器に関するものであり、特にゼリー状の内容物をその胴部を手指で圧しながら注出口（飲み口も含む）から注ぎ易くした注出口装置およびその注出口装置を装備した袋状容器に関する。
【０００２】
【従来の技術】
従来、液状の清涼飲料やゼリー状の飲料（栄養剤などを含めた）などの液体包装容器として、プラスチックフィルムを主体とした軟包装材でなる注出口装置付袋状容器が知られ、その袋の胴部を手指で圧しながら、注出口から飲料等内容物を口などへ注ぐもので、特に流動性に欠けるゼリー状の飲料等に好都合な注出口装置付袋状容器として普及している。
【０００３】
上記のような容器の注出口装置として、例えば上端に位置する口部と袋状容器用接合部と内容物導入部とからなり、この口部と袋状容器用接合部とは内部連通孔で連通されてなり、この袋状容器用接合部で連通孔が開放し、前記内容物導入部は袋状容器用接合部に連結されたパイプ状の脚体からなるものがある。
【０００４】
しかし、このパイプ状の脚体からなる内容物導入部のものでは、ゼリー状の内容物がパイプの中を通るので棒状に固まった不均一なものとなり、内部連通孔で詰まる（閉塞する）等の問題があった。
【０００５】
また、上記のような容器の他の注出口装置として、例えば内容物導入部が袋状容器用接合部に連結された板状の脚体からなるものがある。
【０００６】
しかし、この板状の脚体からなる内容物導入部のものでは、ゼリー状の内容物が板状の脚体で分離されて大きな固まりとなりやすく、よって内部連通孔で詰まる（閉塞する）等の現象が発生しやすいという問題があった。さらに脚体が板状のため成形品に反りが生じたり、成形後の保管、移送等での熱で変形し易い等の問題点があった。
【０００７】
また、上記のような容器の他の注出口装置として、例えば内容物導入部が袋状容器用接合部に連結された縦横リブが直交してなる十字状リブの脚体からなるものがある。
【０００８】
しかしながら、上記十字状リブの脚体からなる内容物導入部のものでは、ゼリー状の内容物は、十字状リブの脚体で比較的均一に砕かれて出てくるので、内部連通孔で詰まる（閉塞する）という問題は解消されているが、重心の位置が上端に位置する口部近傍に偏っているので、この注出口装置を袋状容器に自動的に挿入装着（シール）する作業において、そのストッカーから整列移送に際し、重心の安定性に欠けるので、内容物導入部の挿入装着方向を安定して規制することが困難という問題点があった。
【０００９】
上記内容物導入部の挿入装着方向を安定して規制可能な注出口装置として、例えば特開平１０−１５７７４８号公報に提案されているように、内容物導入部は、袋状容器用接合部に連結された２本の平行する脚状体からなり、この２本の平行する脚状体の先端部で一体化構成として、口部、袋状容器用接合部と内容物導入部のバランスを移送状態で安定よくするため内容物導入部の先端に重量を持たせた注出口装置がある。
【００１０】
しかしながら、この脚状体の先端部を一体化構成として、重量のバランスをよくしたものでは、液状の内容物では問題はないが、ゼリー状の内容物の場合では、袋状容器の胴部を圧しても内部連通孔から出にくく、かつ詰まる（閉塞する）等の現象が発生しやすいという問題があり、さらに内容物導入部が２本の脚状体のみで構成されているので、成形品に反りが生じたり、成形後の保管、搬送等での熱で変形し易い等の問題点や、先端部が厚肉となり成形サイクル上不利となるという問題点があった。
【００１１】
【発明が解決しようとする課題】
本発明は、かかる従来技術の問題点を解決するものであり、その課題とするところは、袋状容器の胴部を手指で圧すことによって、特にゼリー状の内容物を口部から注出するに際し、口部と袋状容器用接合部の内部連通孔で詰まる（閉塞する）という問題がなく（閉塞防止機能を有し）、内容物導入部が反ったり、成形後の保管、搬送等での熱で変形したりせず、かつ口部、袋状容器用接合部と内容物導入部の重さのバランスがとれ、この注出口装置を袋状容器に自動的に挿入装着（シール）する作業において、ストッカーから整列移送に際し、重心の安定性に優れ、内容物導入部の挿入装着方向を安定して規制することができ、さらに導入部の先端部の肉厚を薄くして成形リサイクルに優位な注出口装置とこの注出口装置を備えた袋状容器を提供することにある。
【００１２】
【課題を解決するための手段】
本発明に於いて上記課題を達成するために、まず請求項１の発明では、上端に位置する口部と袋状容器用接合部と内容物導入部とからなり、前記口部と袋状容器用接合部とは内部連通孔で連通されてなり、該袋状容器用接合部で連通孔が開放し、前記内容物導入部は袋状容器用接合部に連結された、口部から内容物導入部の方向に伸びる２本の平行する脚体からなり、これら脚体の外側にこの脚体に沿うリブを設け、かつ脚体の先端に重量調整用先端部が一体化されている注出口装置において、縦横リブが直交してなる十字形状リブの横リブが、前記２本の平行する脚体間に、該脚体伸長方向の略中央部から口部方向に延び、袋状容器用接合部下端からの所定の距離の位置まで、該脚体と一体となるように設けられており、前記注出口装置の重心位置を十字形状リブの口部方向の先端とし、該重心位置を支点とする、十字形状リブの長さ（Ｌ２）と十字形状リブの質量（Ｗ２）の積で表される十字形状リブの重量モーメントと、前記十字形状リブの口部方向の先端から重量調整用先端部までの長さ（Ｌ１）と重量調整用先端部の質量（Ｗ１）の積で表される重量調整用先端部までの重量モーメントが略同量であることを特徴とする注出口装置としたものである。
【００１３】
上記請求項１の発明によれば、２本の平行する脚体の間に、縦横リブが直交してなる十字形状リブの横リブを一体となるように設けることによって、成形品の反りが無くなり、成形後の保管、搬送等での熱による変形も無くなり、かつ特にゼリー状の内容物が均一に砕かれるので、注出に際し、口部と袋状容器用接合部の内部連通孔で詰まるという問題がなくなる注出口装置とすることができ、また、この十字形状リブの設ける位置を、脚体間であって、脚体伸長方向の略中央部から口部方向に延び、袋状容器用接合部下端からの所定の距離の位置までとすることによって、重心の位置が袋状容器用接合部下端近傍となるので、この注出口装置を袋状容器に自動的に挿入装着（シール）する作業において、そのストッカーから整列移送に際し、重心のバランスが図られ、内容物導入部の挿入装着方向を安定して規制することができる注出口装置とすることができる。
また、注出口装置の重心位置を支点とする十字形状リブの重量モーメント即ち十字形状リブの長さ：Ｌ２と十字形状リブの重量：Ｗ２の積、Ｌ２×Ｗ２の値が十字形状リブの口部方向の先端から重量調整用先端部までの重量モーメント即ち十字形状リブの口部方向の先端から重量調整用先端部までの長さ：Ｌ１とその重量：Ｗ１との積、Ｌ１×Ｗ１の値と略同等とすることによって、重量調整用先端部の肉厚を薄くすることができ、よって成形サイクルに優位な注出口装置とすることができる。
【００１４】
また、請求項２の発明では、前記十字形状リブの口部方向の先端と袋状容器用接合部の下端との所定の距離は、３〜１０ｍｍの範囲であることを特徴とする請求項１記載の注出口装置としたものである。
【００１５】
上記請求項２の発明によれば、十字形状リブの口部方向の先端と袋状容器用接合部下端との距離を、３〜１０ｍｍの範囲とすることによって、上端の口部から連通孔を通じて内容物を充填するに際し、十字形状リブで邪魔されることがないので、スムーズな充填を可能にし、この距離が３ｍｍに満たないと、十字形状リブに邪魔されて内容物が通りにくくなり、１０ｍｍを越えると十字形状リブ自体が短くなってゼリー状の内容物を均一に砕くことができなくなるので好ましくない。
【００１６】
また、請求項３の発明では、前記十字形状リブの縦リブの高さは、２本の平行する脚体の縦幅より高くないことを特徴とする請求項１または２記載の注出口装置としたものである。
【００１７】
上記請求項３の発明によれば、縦横リブが直交してなる十字形状リブの縦リブの高さを、２本の平行する脚体の縦幅より高くなく、出っ張らないようにすることによって、この注出口装置を袋状容器に自動的に挿入装着（シール）する作業において、十字形状リブの縦リブが袋状容器に引っ掛かったりする事がなくなるので、挿入装着がスムーズにでき、またこの成形ラインや挿入装着ラインでの整列移送に際し、この縦リブがライン上で引っ掛かったりする事がなくなり、注出口装置の成形ラインや挿入装着ラインでのトラブルを防止する注出口装置とすることができる。
【００２０】
また、請求項４の発明では、前記請求項１、２または３に記載の注出口装置を装備している注出口装置付袋状容器としたものである。
【００２１】
上記請求項４の発明によれば、２本の平行する脚体の内側に、縦横リブが直交してなる十字形状リブが一体となるように設けられている注出口装置を備えた注出口装置付袋状容器とすることによって、消費者の飲食等使用に際し、その袋状容器の胴部を手指で圧すと、特にゼリー状の内容物では均一に砕かれ、連通孔で閉塞することがなく、口部からスムーズに注ぐことができる。
【００２２】
【発明の実施の形態】
以下本発明の実施の形態を図面を用いながら詳細に説明する。
本発明は、図１の斜視図に示すように、例えばゼリー状等の内容物を袋状容器本体（２）に充填し、飲料用や医療用などに使用する注出口装置（３）とそれを備えた注出口装置付袋状容器（１）に関するものであり、特にゼリー状の内容物をその胴部（２１）を手指で圧しながら注出口（飲み口も含む）から注ぐ注出口装置（３）及びその注出口装置（３）を装備した注出口装置付袋状容器（１）である。
【００２３】
上記本発明の注出口装置（３）としては、図２の正面図に示すように、例えば上端に位置する口部（１０）と袋状容器用接合部（１２）と内容物導入部（１４）とからなり、この口部（１０）と袋状容器用接合部（１２）とは内部連通孔（３１）で連通されている。さらにこの内部連通孔（３１）は、袋状容器用接合部（１２）で開放されている。さらにこの内容物導入部（１４）は、袋状容器用接合部の下端に連結された２本の平行する脚体（１５）からなっていて、これら２本の脚体（１５）の外側にこの脚体に沿う外側リブ（１７）が設けられていて、かつ脚体（１５）の先端に重量調整用先端部（１６）が一体化されている注出口装置（３）において、上記請求項１に係わる発明では、この２本の平行する脚体（１５）の内側に、図３に示す図２のＢ−Ｂ面断面図のように、縦リブ（３４）と横リブ（３２）が直交してなる十字形状リブ（３０）の横リブ（３２）が、脚体（１５）と一体となるように設けられている注出口装置（３）とするものである。
【００２４】
上記のように、脚体（１５）の略中央より上部内側に十字形状リブ（３０）の横リブ（３２）を一体化せしめて設けることによって、この注出口装置（１）に反りが無くなり、成形後の保管、搬送等での熱による変形も無くなり、かつ特にゼリー状の内容物が均一に砕かれるので、注出に際し、口部（１０）と袋状容器用接合部（１２）の内部連通孔（３１）で詰まるという問題を防止することができる。
【００２５】
さらに上記請求項１に係わる発明では、図２に示すように、例えば十字形状リブ（３０）を、脚体（１５）と一体化せしめる位置を、２本の平行する脚体（１５）の内側で、その伸長方向の略中央部から口部（１０）方向に向かって、袋状容器用接合部（１２）の下端から所定の距離（Ｌ）の位置までとしたもので、この位置に十字形状リブ（３０）を設けることによって、重心が袋状容器用接合部（１２）の下端近傍となり、図１に示すように、この注出口装置（３）の袋状容器用接合部（１２）を袋状容器本体（２）に自動的に挿入装着（シール）する作業のストッカーからの整列移送に際し、重心のバランスが図られ、内容物導入部（１４）の挿入装着方向を安定して規制することができる。
また、上記請求項１に係わる発明では、図２に示すように、注出口装置（３）の重心位置を十字形状リブ（３０）の口部方向の先端とし、この重心位置を支点とする十字形状リブ（３０）の重量モーメント即ち十字形状リブ（３０）の長さ（Ｌ２）と十字形状リブ（３０）の重量：Ｗ２の積、Ｌ２×Ｗ２の値が、十字形状リブの口部方向の先端から重量調整用先端部（１６）までの重量モーメント即ち十字形状リブの口部方向の先端から重量調整用先端部までの長さ（Ｌ１）とその重量：Ｗ１との積、Ｌ１×Ｗ１の値と略同等としたもので、それによって重量調整用先端部（１６）の肉厚を薄くすることができ、よって成形サイクルに優位な注出口装置（３）とすることができる。
【００２６】
また、上記請求項２に係わる発明では、図２に示すように、上記十字形状リブ（３０）の口部（１０）方向の先端と袋状容器用接合部（１２）の下端からの距離（Ｌ）を、５〜１５ｍｍの範囲としたもので、このような距離（Ｌ）とすることによって、注出に際し適度の長さを持った十字形状リブ（３０）でゼリー状の内容物を均一に砕き、かつ口部（１０）からの充填に際しゼリー状の内容物が十字形状リブ（３０）に邪魔される危惧がなくスムーズに充填可能な注出口装置（３）とすることができる。
【００２７】
さらにまた、上記請求項３に係わる発明では、図２のＢ−Ｂ面断面図である図３に示すように、縦リブ（３４）と横リブ（３２）が直交してなる十字形状リブ（３０）の縦リブ（３４）の高さ（Ｈ）を、２本の平行する脚体（１５）の縦幅（Ｗ）と同等もしくは僅かに低くしたもので、このようにすることによって、例えば図１に示すように、この注出口装置（３）を袋状容器本体（２）に自動的に挿入装着（シール）する作業において、十字形状リブの縦リブ（図示せず）が袋状容器本体（２）に引っ掛かったりする危惧がなくなり、またこの注出口装置の成形ラインや挿入装着ラインでの整列移送に際し、図３に示すこの縦リブ（３４）がライン上で引っ掛かったりする事がなくなり、成形ラインや挿入装着ラインでのトラブルを防止することができる。
【００２８】
また、上記請求項４に係わる発明では、図２に示すように、注出口装置（３）の重心位置が、十字形状リブ（３０）の口部方向の先端とし、この重心位置を支点とする十字形状リブ（３０）の重量モーメント即ち十字形状リブ（３０）の長さ（Ｌ２）と十字形状リブ（３０）の重量：Ｗ２の積、Ｌ２×Ｗ２の値が、十字形状リブの口部方向の先端から重量調整用先端部（１６）までの重量モーメント即ち十字形状リブの口部方向の先端から重量調整用先端部までの長さ（Ｌ１）とその重量：Ｗ１との積、Ｌ１×Ｗ１の値と略同等としたもので、それによって重量調整用先端部（１６）の肉厚を薄くすることができ、よって成形リサイクルに優位な注出口装置（３）とすることができる。
【００２９】
また、上記請求項４に係わる発明では、図１に示すように、例えば上記機構の注出口装置（３）を、プラスチックフィルムを主体とした軟包装材製のガゼット袋でなる袋状容器本体（２）の口部（２２）に挿入装着してなる注出口装置付袋状容器（１）とするもので、消費者は、例えばゼリー状飲料が充填された注出口装置付容器（１）のキャップ（４ａ）を外し、容器の胴部（２１）を手指で掴んで圧しながら、注出口装置（３）の口部（１０）に口を当て、注出口装置（３）の十字形状リブ（３０）で均一に砕かれたゼリー状飲料がこの口部（１０）からスムーズに注出されて、そのゼリー状飲料を飲食することができるもので、このように本発明は、利便性に優れた注出口装置付袋状容器（１）を提供することができる。
【００３０】
上記本発明の注出口装置付袋状容器（１）の製造は、例えば、上記構成の注出口装置（３）をストッカーから、重心のバランスが図られた吊下移送状態で、注出口装置（３）の挿入装着部に移送し、図１に示す袋状容器本体（２）の口部（２２）にバランスよく挿入し、注出口装置（３）の袋状容器用接合部（１２）と袋状容器本体（２）の口部（２２）とを熱圧着等でシールして注出口装置付袋状容器（１）とする。このような構成の注出口装置付袋状容器（１）に、注出口装置（３）の口部（１０）から、飲料用等内容物を充填して注出口装置付袋状容器（１）の商品とするものである。
【００３１】
以下に本発明の注出口装置および注出口装置付袋状容器の材料等について説明する。
まず上記注出口装置（３）としては、その材料としてポリエチレン、ポリプロピレン、ポリエチレンテレフタレート、ナイロンなどの汎用樹脂が挙げられ、内容物や用途等に応じて適宜選定され、これら樹脂の射出成形法によって得られる。この注出口装置（３）のサイズは、注出口装置（３）の口部（１０）を飲み口とする等の用途から、例えば図２に示すように、この口部（１０）の外径が１０ｍｍ程度、口部（１０）と袋状容器用接合部（１２）の長さが３５ｍｍ程度、内容物導入部（１４）の長さが７０ｍｍ程度のものが一般的であり、また図３に示すように、本発明に係わる十字形状リブ（３０）を構成する縦リブ（３４）の高さ（Ｈ）は、２本の平行する脚体（１５）の縦幅（Ｗ）６ｍｍ程度より高くないようにし、即ち６ｍｍ〜４ｍｍ程度とすることが好ましい。
【００３２】
本発明の注出口装置付袋状容器（１）の袋状容器本体（２）に用いられる材料としては、特に限定されるものではなく、充填すべき内容物、包装用途に対応して適宜に選定できるものであり、例えばポリエチレン、ポリプロピレン、ポリエチレンテレフタレート、ナイロン、エチレン−酢酸ビニル共重合体、エチレン−ビニルアルコール共重合体など、あるいはこれらの複合材料などが挙げられる。さらに例えば充填される内容物がビタミン剤のように外部の光やガス等によってビタミンが破壊されるのを防ぐため、その材料として、アルミニウム箔を上記プラスチックフィルムでサンドした積層フィルムを使用する場合もある。また、袋に透明性が要求され、かつ酸素や水蒸気に対するガスバリア性を要求される場合は、アルミニウム箔の代わりに無機酸化物（Ａｌ２Ｏ３、ＳｉＯ２、ＭｇＯなど）からなる蒸着薄膜が使用される。これら積層材料を袋（容器）状とするため、熱圧着シール法が一般的であって、そのためには、積層材料の最内層にはヒートシール性に優れた直鎖低密度ポリエチレン、低密度ポリエチレン、無延伸ポリプロピレン、あるいはエチレン−酢酸ビニル共重合体などでなる層が好適に用いられる。
【００３３】
本発明の注出口装置付袋状容器（１）の用途は、例えば食品業界での清涼飲料水、ビタミン等栄養剤、ミネラルウォーター、ミルク、食料油類、コーヒーや酒等嗜好品、お粥等流動食類、化学品業界での各種薬品、液状洗剤、入浴剤など、あるいは自動車関連業界でのモーターオイル、ウオッシャー液、バッテリー液などの液状またはゼリー状内容物の充填および注出用として有用なものであり、特に本発明に係わる十字形状リブを内容物導入部に備えたものは、ゼリー状の飲食料品用途において、上述のように、口部に口を付け、袋を片手で押しながら飲食することができる非常に便利なものとして有用である。
【００３４】
【発明の効果】
本発明は以上の構成であるから、下記に示す如き効果がある。
即ち、まず請求項１に係わる発明においては、上端に位置する口部と袋状容器用接合部と内容物導入部とからなり、口部と袋状容器用接合部と内部連通孔で連通されてなり、前記内容物導入部は袋状容器用接合部に連結された２本の平行する脚体からなり、かつ脚体の先端に重量調整用先端部が一体化されている注出口装置において、前記２本の平行する脚体の内側に、縦横リブが直交してなる十字形状リブの横リブを一体となるように設けることによって、成形品の反りが無くなり、成形後の保管、搬送等での熱による変形も無くなり、かつ特にゼリー状の内容物が均一に砕かれるので、注出に際し、口部と袋状容器用接合部の内部連通孔で詰まるという問題がなくなる注出口装置とすることがでる。また、この十字形状リブの設ける位置を、脚体の内側の略中央部から口部方向に延び、袋状容器用接合部下端からの所定の距離の位置までとすることによって、重心の位置が袋状容器用接合部下端近傍となるので、この注出口装置を袋状容器に自動的に挿入装着（シール）する作業において、そのストッカーから整列移送に際し、重心のバランスが図られ、内容物導入部の挿入装着方向を安定して規制することができる注出口装置とすることができる。
さらにまた、上記請求項１に係わる発明においては、注出口装置の重心位置を十字形状リブの口部方向の先端とし、この重心位置を支点とする十字形状リブの重量モーメント即ち十字形状リブの長さ：Ｌ２と十字形状リブの重量：Ｗ２の積、Ｌ２×Ｗ２の値が十字形状リブの口部方向の先端から重量調整用先端部までの重量モーメント即ち十字形状リブの口部方向の先端から重量調整用先端部までの長さ：Ｌ１とその重量：Ｗ１との積、Ｌ１×Ｗ１の値と略同等とすることによって、重量調整用先端部の肉厚を薄くすることができ、よって成形サイクルに優位な注出口装置とすることができる。
【００３５】
また、上記請求項２に係わる発明においては、上記十字形状リブの口部方向の先端と袋状容器用接合部下端との距離を、３〜１０ｍｍの範囲とすることによって、上端の口部から連通孔を通じて内容物を充填するに際し、十字形状リブで邪魔されることがないので、スムーズな充填を可能にする注出口装置とすることができる。
【００３６】
また、上記請求項３に係わる発明においては、上記縦横リブが直交してなる十字形状リブの縦リブの高さを、２本の平行する脚体の縦幅より高くなく、出っ張らないようにすることによって、袋状容器の口部に自動的に挿入装着（シール）する作業において、十字形状リブの縦リブがこの袋状容器に引っ掛かったりする事がなくなるので、挿入装着がスムーズにでき、またこの成形ラインや挿入装着ラインでの整列移送に際し、この縦リブがライン上で引っ掛かったりする事がなくなり、成形ラインや挿入装着ラインでのトラブルを防止する注出口装置とすることができる。
【００３８】
また、上記請求項４に係わる発明においては、上記２本の平行する脚体の内側に、縦横リブが直交してなる十字形状リブが一体となるように設けられている注出口装置を備えた注出口装置付袋状容器とすることによって、消費者の飲食等使用に際し、その袋状容器の胴部を手指で圧すと、特にゼリー状の内容物では均一に砕かれ、口部と袋状容器用接合部の連通孔で閉塞することがなく、口部からスムーズに注ぐことができる利便性に優れた注出口装置付袋状容器とすることができる。
【００３９】
従って本発明は、液状、ゼリー状等の内容物を充填し、飲料用や医療用などに使用する注出口装置とそれを備えた注出口装置付袋状容器において、特にゼリー状の内容物をその胴部を手指で圧しながら口部（飲み口も含む）から注ぎ易くした注出口装置およびその注出口装置を装備した袋状容器として、優れた実用上の効果を発揮する。

BACKGROUND OF THE INVENTION
The present invention relates to a spout device that is filled with liquid or jelly-like contents and is used for beverages or medical purposes, and a bag-like container with a spout device provided with the spout device, and in particular, the jelly-like contents The present invention relates to a spout device that facilitates pouring an object from a spout (including a spout) while pressing the body part with fingers, and a bag-like container equipped with the spout device.
[0002]
[Prior art]
Conventionally, as a liquid packaging container for liquid soft drinks and jelly-like drinks (including nutrients), a bag-like container with a spout device made of a soft packaging material mainly composed of a plastic film is known. It is widely used as a bag-like container with a spout device, which is suitable for jelly-like beverages that lack fluidity, and the like.
[0003]
As the container spout device as described above, for example, it comprises a mouth portion located at the upper end, a bag-like container joint portion and a content introduction portion, and this mouth portion and the bag-like container joint portion are internal communication holes. In some cases, the communication hole is opened at the joint portion for the bag-like container, and the content introducing portion is formed of a pipe-like leg connected to the joint portion for the bag-like container.
[0004]
However, in the case of the contents introduction portion composed of this pipe-shaped leg, the jelly-shaped contents pass through the pipe and become non-uniformly solidified in a rod shape, and are clogged (closed) by the internal communication holes. There was a problem.
[0005]
Moreover, as another spout apparatus of the above containers, there exist some which consist of a plate-shaped leg body with which the content introduction part was connected with the junction part for bag-shaped containers, for example.
[0006]
However, in the contents introduction portion composed of the plate-like legs, the jelly-like contents are easily separated into large pieces by the plate-like legs, and are therefore clogged (closed) by the internal communication holes. There was a problem that the phenomenon was likely to occur. Further, since the legs are plate-shaped, there are problems such as warpage of the molded product, and easy deformation due to heat in storage, transfer, etc. after molding.
[0007]
As another example of the container spouting device as described above, there is a device composed of legs of cross-shaped ribs in which the vertical and horizontal ribs whose content introduction part is connected to the joint part for bag-like containers are orthogonal to each other.
[0008]
However, in the case of the content introduction portion composed of the legs of the cross-shaped rib, the jelly-shaped contents are crushed relatively uniformly by the legs of the cross-shaped rib, and are thus blocked by the internal communication holes. Although the problem of (blocking) has been solved, the position of the center of gravity is biased to the vicinity of the mouth located at the upper end, so in the operation of automatically inserting (sealing) this spout device into the bag-like container In the alignment transfer from the stocker, the stability of the center of gravity is lacking, so that there is a problem that it is difficult to stably regulate the insertion and mounting direction of the content introducing portion.
[0009]
As a spout device capable of stably regulating the insertion and mounting direction of the content introduction part, for example, as proposed in Japanese Patent Laid-Open No. 10-157748, the content introduction part is connected to a bag-like container joint. Consists of two parallel legs connected, and the balance between the mouth, the joint for bag-like container and the contents introduction part is transferred as an integrated structure at the tip of the two parallel legs. There is a spout device in which a weight is given to the tip of the content introduction part in order to improve stability in the state.
[0010]
