【発明の属する技術分野】
本発明は、清酒、果汁飲料、調味料、油類や液体洗剤などに使用される液体用紙容器の頂部に突設される開封刃を内蔵する注出口栓に関するものである。
【０００２】
【従来の技術】
従来、液体用紙容器（２０）は、例えば図５に示すように、四角形状の胴部をもち、その切妻屋根形の頂部傾斜板（２１）には、注出のし易さから注出口栓（１０）が突設されたものが広く使用されていた。この注出口栓は、スパウト（１００）（注出口具）にキャップ（２００）を冠着したものであり、注出口栓に開封刃を内蔵するものは、例えば実公平５−３５０５８号公報で開示されたものがある。この開封刃を内蔵する注出口栓は、破断可能なフィルムで封止した液体用紙容器の注出孔に取着されこの注出孔に対応した円筒部を備える注出口具と、この注出口具の円筒部に挿入され下縁に刃部を備える略筒状の開封刃と、円筒部を覆うようにして取着されたキャップとからなり、円筒部の内面とこれに相対する開封刃の外面との両者は、互いに摺接して上下方向に移動可能な回転防止手段を備えて、開封刃が円筒部に対して上下移動可能に設けられ、開封刃は、開封刃の筒壁部に上縁から下縁側に向けて傾斜して上方に面する斜面を備え、キャップは、下方に面して開封刃の斜面に摺接する案内斜面を備える筒体を有して、キャップの回転時に開封刃を下降可能に設けたものであり、内容物を注出時に、図５に示すように、キャップ（２００）を回転させて取り外すときに、キャップの回転により開封刃（１４２）を降下させて封止するフィルム（３０）を破断して容器を開封するものであった。
【０００３】
【発明が解決しようとする課題】
ところで、最近、環境保全や省資源の立場から、使用済みの容器包装を分別回収して、再商品化することが求められるようになってきた。しかしながら、上述の従来の開封刃を内蔵する注出口栓を取り付けた液体用紙容器（２０）は、図５に示すように、注出口栓（１０）の開封刃（１４２）が容器の内側に突出したままになっていると、容器を解体して分別回収するときに、手などに怪我をし易い危惧があった。
【０００４】
本発明は、上述の従来の開封刃を内蔵する注出口栓の問題を解決したものであり、液体用紙容器を解体して分別回収するときに、注出口栓の開封刃で手などに怪我をする危惧のない開封刃を内蔵する注出口栓を提供するものである。
【０００５】
【課題を解決するための手段】
本発明の第１の発明は、図１及び図３に示すように、破断可能な封止フィルム（３０）で封止された液体用紙容器（２０）の注出孔に突設される開封刃（１４２）を内蔵するスパウト（１００）とキャップ（２００）とからなる注出口栓において、前記キャップ（２００）の天板（２１０）下面に、上段筒（２３１）とこの上段筒より径が小さい下段筒（２３２）とからなり、且つ、それぞれの外周面に螺旋状の複数の案内斜面（２３３と２３４）を形成する二段のガイド用内筒（２３０）を垂設し、前記スパウト（１００）の注出筒（１２０）内面に複数の縦溝（１２２）を形成し、前記スパウトの注出筒内に、前記縦溝を摺動する複数の突起（１３１）を外周面にもち、内面に複数の縦溝（１３２）を形成し、且つ、内周面に前記ガイド用内筒の上段筒の案内斜面（２３３）と摺接する複数の案内斜面（１３３）を形成するカバー用筒体（１３０）を摺動可能に挿着し、このカバー用筒体の縦溝（１３２）に摺動する複数の突起（１４１）を外周面にもち、下端に開封刃（１４２）を形成し、且つ、内周面に前記ガイド用内筒の下段筒の案内斜面（２３４）と摺接する複数の案内斜面（１４４）を形成する開封用筒体（１４０）を摺動可能に挿着し、キャップを取り外す途中において、降下する開封用筒体の先端の開封刃で封止フィルムを破断し、キャップを取り外したときには、カバー用筒体の先端が開封用筒体の先端より下降することを特徴とする開封刃を内蔵する注出口栓（１０）である。
【０００６】
本発明の第２の発明は、図３に示すように、前記ガイド用内筒（２３０）の上段筒（２３１）の案内斜面（２３３）及び前記カバー用筒体（１３０）の案内斜面（１３３）を、所定の回転範囲の下端から上端へ螺旋状に形成し、且つ、前記ガイド用内筒の下段筒（２３２）の案内斜面（２３４）及び前記開封用筒体（１４０）の案内斜面（１４４）を、前記ガイド用内筒及びカバー用筒体の案内斜面を形成した回転範囲より狭い回転範囲の下端から上端へ螺旋状に形成したことを特徴とする第１の発明に記載の開封刃を内蔵する注出口栓である。
【０００７】
本発明の開封刃を内蔵する口栓を頂部に突設した液体用紙容器は、キャップを取り外すためにキャップを左回転して上昇させると、キャップの天板から垂設するガイド用内筒の上段筒の外周面の案内斜面と摺接する案内斜面を内周面にもちスパウトの注出筒内側に収容されているカバー用筒体が、右回転方向の力を受けるが、カバー用筒体の外周面の突起がスパウトの注出筒の縦溝と摺接しているため、縦溝に沿ってカバー用筒体が下方に移動する。同様に、キャップのガイド用内筒の下段筒の外周面の案内斜面と摺接する案内斜面を内周面にもちカバー用筒体内側に収容されている開封用筒体が、右回転方向の力を受けるが、開封用筒体の外周面の突起がカバー用筒体の縦溝と摺接しているため、縦溝に沿って開封用筒体が下方に移動する。このため、キャップを取り外す途中で、図２に示すように、下降する開封用筒体（１４０）の下端の開封刃（１４２）が容器を封止する封止フィルム（３０）を破断して容器を開封し、キャップを取り外したときには、図３に示すように、容器の内側に突出した開封用筒体（１４０）の先端の開封刃（１４２）よりカバー用筒体（１３０）の先端が降下して、開封用筒体をカバー用筒体が覆うため、使用後の容器を解体して分別回収するときに、手などを怪我する危惧がない。
【０００８】
また、ガイド用内筒の上段筒の案内斜面及びカバー用筒体の案内斜面を形成する回転範囲よりも、ガイド用内筒の下段筒の案内斜面及び開封用筒体の案内斜面を形成する回転範囲を狭くした本発明の開封刃を内蔵する口栓は、前者の案内斜面の勾配よりも後者の案内斜面の勾配が急勾配になるため、カバー用筒体の降下速度よりも開封用筒体の降下速度が早くなり、キャップの取り外す途中では、開封用筒体の先端の開封刃がカバー用筒体の先端より早く封止フィルムに到達し、且つ、降下速度が早いので封止フィルムの破断性が良好となる。
【０００９】
【発明の実施の形態】
本発明の開封刃を内蔵する注出口栓は、図１に示すように、破断可能な封止フィルム（３０）で封止された液体用紙容器（２０）の注出孔に突設されるものであり、スパウト（１００）とカバー用筒体（１３０）と開封用筒体（１４０）とキャップ（２００）とから構成される。これら構成部材は、ポリエチレン、ポリプロピレンなどの熱可塑性樹脂を用いて射出成形法で作製するものである。なお、口栓の液体用紙容器への取り付けは、例えば、スパウトの下方のフランジ（１１０）の下面を、容器の頂部傾斜板の上面に超音波シール法などにより熱融着するものである。
【００１０】
そして、キャップ（２００）は、図３に示すように、周壁（２２０）の内周面にスパウトとの螺合部（２２１）を形成し、天板（２１０）の下面に、上段筒（２３１）とこの上段筒より径が小さい下段筒（２３２）とからなる二段のガイド用内筒（２３０）を垂設したものであり、このガイド用内筒の上段筒の外周面に螺旋状で通常２本の複数の案内斜面（２３３）を通常１８０度の使用目的に適合する回転範囲で下端から上端に形成し、下段筒の外周面に螺旋状で通常２本の複数の案内斜面（２３４）を通常９０度の使用目的に適合する回転範囲で下端から上端に形成し形成するものである。
【００１１】
また、スパウト（１００）は、図１及び図３に示すように、フランジ（１１０）に注出筒（１２０）を立設したもので、この注出筒の外周面にキャップとの螺合部（１２１）を形成し、内面には通常８本からなる複数の縦溝（１２２）を形成したものであり、この縦溝を摺動する通常４個の複数の突起（１３１）を外周面にもち、内面に通常８本の複数の縦溝（１３２）を形成し、且つ、内周面にキャップのガイド用内筒の上段筒の案内斜面（２３３）と摺接する通常２本の複数の案内斜面（１３３）を形成するカバー用筒体（１３０）を摺動可能に挿着し、このカバー用筒体の縦溝（１３２）に摺動する通常４個の複数の突起（１４１）を外周面にもち、下端に開封刃（１４２）を形成し、且つ、内周面に前記ガイド用内筒の下段筒の案内斜面（２３４）と摺接する通常２本の複数の案内斜面（１４４）を形成する開封用筒体（１４０）を摺動可能に挿着するものである。なお、開封用筒体の下端に形成する開封刃（１４２）は、通常、複数の三角歯を並べたものでありが、封止フィルムの破断片（３１）が容器内へ落下することを防ぐために、一部に欠刃部（１４２）を設けるものである。
【００１２】
そして、キャップを取り外す途中において、降下する開封用筒体の先端の開封刃で封止フィルムを破断し、キャップを取り外したときには、容器内側に突出する開封用筒体をカバー用筒体が覆い隠すように、商品企画時に設計するものである。
フランジ（１１０）の下面に封止フィルムを貼り付け、キャップは容器内面より注出口に差し込み、フランジと液体用紙容器をヒートシールする構造としても良い。
【００１３】
【発明の効果】
本発明の開封刃を内蔵する注出口栓を取り付けた液体用紙容器は、使用後の分別回収のために容器を解体しても、容器の内側に突出する開封刃がカバー用筒体で覆われているため、手などに怪我をする危惧がない。

[0003]
[Problems to be solved by the invention]
By the way, recently, from the standpoints of environmental protection and resource saving, it has been demanded to separate and collect used containers and packaging for re-commercialization. However, in the liquid paper container (20) to which the above-described conventional opening blade is installed, the opening blade (142) of the outlet plug (10) protrudes inside the container as shown in FIG. If left untreated, there was a risk of hand injury when the container was disassembled and collected separately.
[0004]
The present invention solves the above-described problem of the spout stopper with a built-in opening blade. When the liquid paper container is disassembled and separated and collected, the hand or the like is injured by the spout opening blade. It is an object of the present invention to provide a spout stopper with a built-in unsealed opening blade.
[0005]
[Means for Solving the Problems]
As shown in FIGS. 1 and 3, the first invention of the present invention is an unsealing blade projecting from a dispensing hole of a liquid paper container (20) sealed with a breakable sealing film (30). In the spout stopper comprising the spout (100) containing the (142) and the cap (200), the upper tube (231) and the upper tube are smaller in diameter on the lower surface of the top plate (210) of the cap (200). A two-stage guide inner cylinder (230) comprising a lower cylinder (232) and forming a plurality of spiral guide slopes (233 and 234) on each outer peripheral surface is suspended, and the spout (100 A plurality of vertical grooves (122) are formed on the inner surface of the pouring cylinder (120) of the outer surface of the spout, and a plurality of protrusions (131) sliding in the vertical grooves are provided on the outer surface of the spouting cylinder of the spout. A plurality of vertical grooves (132) are formed in the inner peripheral surface, and the guide is formed on the inner peripheral surface. A cover cylinder (130) that forms a plurality of guide slopes (133) in sliding contact with the guide slope (233) of the upper cylinder of the inner cylinder is slidably inserted, and a longitudinal groove (132) of the cover cylinder is formed. ) Have a plurality of projections (141) on the outer peripheral surface, an opening blade (142) is formed at the lower end, and the guide slope (234) of the lower cylinder of the guide inner cylinder slides on the inner peripheral surface. The opening cylinder (140) that forms a plurality of guide slopes (144) that come into contact is slidably inserted, and the sealing film is broken by the opening blade at the tip of the opening cylinder that falls while the cap is being removed. When the cap is removed, the spout plug (10) has a built-in opening blade that is characterized in that the tip of the cover cylinder descends from the tip of the opening cylinder.
[0006]
As shown in FIG. 3, the second invention of the present invention is a guide slope (233) of the upper cylinder (231) of the guide inner cylinder (230) and a guide slope (133) of the cover cylinder (130). ) In a spiral shape from the lower end to the upper end of the predetermined rotation range, and the guide slope (234) of the lower cylinder (232) of the guide inner cylinder and the guide slope (234) of the opening cylinder (140) 144) is formed in a spiral shape from the lower end to the upper end of the rotation range narrower than the rotation range in which the guide slope of the guide inner cylinder and the cover cylinder is formed. It is a spout plug with built-in.
[0007]
The liquid paper container in which the cap that incorporates the opening blade of the present invention protrudes from the top of the guide inner cylinder that is suspended from the top plate of the cap when the cap is rotated leftward and lifted to remove the cap. The cylinder for the cover, which has a guide slope that is in sliding contact with the guide slope on the outer peripheral surface of the cylinder and has an inner peripheral surface, receives a force in the clockwise direction, but the outer periphery of the cover cylinder Since the projection on the surface is in sliding contact with the vertical groove of the spout tube of the spout, the cover cylinder moves downward along the vertical groove. Similarly, the opening cylinder that has a guide slope that slides in contact with the guide slope on the outer peripheral surface of the lower cylinder of the cap guide inner cylinder and that is housed inside the cover cylinder has a force in the clockwise direction. However, since the protrusion on the outer peripheral surface of the opening cylinder is in sliding contact with the longitudinal groove of the cover cylinder, the opening cylinder moves downward along the longitudinal groove. Therefore, in the middle of removing the cap, as shown in FIG. 2, the opening blade (142) at the lower end of the lowering opening cylinder (140) breaks the sealing film (30) that seals the container, and the container When the cap is removed and the cap is removed, as shown in FIG. 3, the tip of the cover cylinder (130) descends from the opening blade (142) at the tip of the opening cylinder (140) protruding inside the container. Then, since the opening cylinder is covered with the cover cylinder, there is no risk of injury to the hand or the like when the used container is disassembled and collected separately.
[0008]
In addition, the rotation that forms the guide slope of the lower cylinder of the guide inner cylinder and the guide slope of the opening cylinder is larger than the rotation range that forms the guide slope of the upper cylinder of the guide inner cylinder and the guide slope of the cover cylinder. The stopper with a built-in opening blade of the present invention with a narrow range has a steeper slope of the latter guide slope than the former guide slope, so that the opening cylinder is faster than the lowering speed of the cover cylinder. When the cap is being removed, the opening blade at the tip of the opening cylinder reaches the sealing film earlier than the tip of the cover cylinder, and the lowering speed is high, so the sealing film breaks. Property is improved.
[0009]
