上記構成を有するこの発明は、以下の様に作用機能する。
この発明における液体用包装容器は、破断可能な封止フィルムで封止された注出孔を頂部に有する。その容器は、紙などの積層包装材料より形成され、その包装材料が容器頂部で穿孔されて注出孔が形成されている。その注出孔がバリア性プラスチックフィルムなどで封止されている。
そのスパウトの基部は、容器頂部であって注出孔の近傍に接合され、注出栓を容器に固着し支持する。スパウトの注出筒は、容器内容物の液体を注ぎ出す通路を形成する。
その開封刃は、スパウトに内蔵され、キャップの開封時の螺旋状上運動に連動して螺旋状に下方運動する。その結果、その開封刃は、注出孔の破断可能な封止フィルムを破断する。
The present invention having the above configuration functions as follows.
The packaging container for liquid in this invention has the pouring hole sealed with the sealing film which can be fractured | ruptured in the top part. The container is formed of a laminated packaging material such as paper, and the packaging material is perforated at the top of the container to form a pouring hole. The pouring hole is sealed with a barrier plastic film or the like.
The base of the spout is joined to the top of the container and in the vicinity of the pouring hole, and the pouring stopper is fixed to and supported by the container. The spout pour tube forms a passage through which the liquid in the container is poured.
The opening blade is built in the spout and moves downward in a spiral manner in conjunction with the upward movement of the spiral when the cap is opened. As a result, the opening blade breaks the sealing film that can break the pouring hole.
キャップは、スパウトを覆い、注出孔を保護するとともに、開封時にキャップの回転運動が開封刃のフィルム破断力を生む。そのキャップには、複数の第１係合フィンが設けられている。その第１係合フィンがキャップの天板下面から実質的に垂直に設けられ、開封刃に回転力を伝動する。
キャップの内周面と該スパウトの注出筒の外周面とに、螺旋状に上下させる第１螺合部と第２螺合部、すなわち、ネジ、若しくは、ネジ状突条／溝が、それぞれ設けられている。キャップを回転させることにより、第１螺合部と第２螺合部に沿って螺旋状に上下に滑動する。キャップを開閉することができる。
The cap covers the spout and protects the spout hole, and the rotational movement of the cap generates a film breaking force of the opening blade at the time of opening. The cap is provided with a plurality of first engagement fins. The first engagement fin is provided substantially vertically from the lower surface of the top plate of the cap, and transmits a rotational force to the opening blade.
A first screwing portion and a second screwing portion that are spirally moved up and down on the inner peripheral surface of the cap and the outer peripheral surface of the spout pipe of the spout, that is, a screw or a screw-like protrusion / groove, respectively. Is provided. By rotating the cap, the cap slides up and down spirally along the first screwing portion and the second screwing portion. Cap can be opened and closed.
スパウトには、その注出筒の内周面に設けられた第３螺合部を有する。開封刃は、その第３螺合部と、円筒部の外周面の第４螺合部とで螺合する。その螺合により、キャップの螺旋状上運動に連動して螺旋状に下運動する、すなわち、キャップの上昇により、開封刃が下降する。円筒部の下端に設けらる刃が、先ず、注出孔の封止フィルムの１点を容易に破断する。
更に、キャップを回転して上昇させると、開封刃は回転しながら下降するので、刃が封止フィルムを円形に切断する。
The spout has a third threaded portion provided on the inner peripheral surface of the dispensing cylinder. The opening blade is screwed by the third screwing portion and the fourth screwing portion of the outer peripheral surface of the cylindrical portion. By the screwing, the opening blade is moved downward in a spiral manner in conjunction with the upward movement of the cap in a spiral manner, that is, the opening blade is lowered by the rising of the cap. First, the blade provided at the lower end of the cylindrical portion easily breaks one point of the sealing film of the pouring hole.
Further, when the cap is rotated and raised, the opening blade descends while rotating, so that the blade cuts the sealing film into a circle.
開封刃の円筒部の内周面に上下垂直に設けられた第２係合フィンは、キャップの係合フィンとキャップの螺旋状上運動時に係合して回転力をキャップから開封刃に伝動するが、キャップの螺旋状下運動時に確実に係合しない。その結果、キャップが開封時に上昇回転すると同時に、確実に、開封刃が下方に回転し、フィルムを破断し、もし、キャップが螺旋状下運動に転じても、開封刃は下降せずその位置に留まる。 The second engagement fin provided vertically on the inner peripheral surface of the cylindrical portion of the opening blade engages with the engagement fin of the cap during the spiral upward movement, and transmits rotational force from the cap to the opening blade. However, they do not engage reliably during the helical downward movement of the cap. As a result, at the same time as the cap is rotated upward at the time of opening, the opening blade is rotated downward to break the film. stay.
キャップがスパウトから離脱するので、刃が封止フィルムを容器注出孔から完全に切断されず、容器内部に落下すること無い。
開封が終了し、キャップがスパウトから離脱すると、第１係合フィンと第２係合フィンとがいずれも上下垂直に設けられているので、万が一にも、開封刃がスパウト若しくは容器に係合していても、キャップが、開封刃から容易に上方に離脱する。
Since the cap is detached from the spout, the blade does not completely cut the sealing film from the container pouring hole and does not fall into the container.
When the opening is finished and the cap is detached from the spout, the first engaging fin and the second engaging fin are both vertically provided, so that the opening blade is engaged with the spout or the container. The cap easily disengages upward from the opening blade.
この発明の好ましい態様における注出口栓では、開封刃の円筒部の内部空間を横断するフィルタを有する。
キャップを回転して上昇させると、開封刃は回転しながら下降するので、刃が封止フィルムを円形に切断する。刃が封止フィルムを容器注出孔から完全に切断したとしても、フィルタがフィルムを捕捉しフィルムが容器から出て誤飲される恐れが無い。
The spout stopper according to a preferred embodiment of the present invention has a filter that traverses the internal space of the cylindrical portion of the opening blade.
When the cap is rotated and raised, the opening blade descends while rotating, so the blade cuts the sealing film into a circle. Even if the blade completely cuts the sealing film from the container pouring hole, there is no possibility that the filter captures the film and the film comes out of the container and is accidentally swallowed.
この発明の特徴における注出口栓は、スパウトの注出筒の内周面に設けられた第３螺合部の凹面に断面くさび状突起を有し、開封刃の円筒部外周面の第４螺合部の凸条に上下方向に逃げ領域を形成される。
