【発明の属する技術分野】
本発明は、液体用紙容器の内面から封止フィルムで封止する注出孔予定位置上に、接着して用いる開封機能付口栓に関するものである。
【0002】
【従来の技術】
従来、紙を主体とする積層シートからなる液体用紙容器の少なくとも中央に直線状のミシン目又は切れ目を入れた注出孔予定位置は、内面から封止フィルムによって封止されているが、この注出孔予定位置上に接着して用いる口栓は、封止フィルムを破断する開封機能をもつ開封機能付口栓であり、例えば、図5(a)及び(b)に示すように、前方が円弧状で左右両側と後方が直線状の注出筒壁(110)の下端外周に、液体用紙容器の上面に下面を接着するフランジ(150)を水平に周設し、このフランジの注出筒壁の後方位置に、左右方向へ直線状で後方注出筒壁幅の蓋取付壁(160)を、注出筒壁の高さと同じ高さで立設し、この蓋取付壁の上端後方面に、薄肉ヒンジ(161)を介して、天板(210)下面に注出筒壁(110)との封止リング(211)をもつ蓋(200)を開閉可能に接続し、注出筒壁内の開口部(130)に、下面に前後方向へ直線突起状の開封刃(145)を有し、後方へ幅が漸次狭くなる開封フラップ(140)を、後方の注出筒壁内面に薄肉ヒンジ(111)を介して前方へ水平に突設し、液体用紙容器の注出孔予定位置を開口するときは、図5(b)に示すように、蓋部(200)を口栓本体(100)の注出筒壁(110)上端から後方へ蓋取付壁(160)の上端薄肉ヒンジ(161)を支線として開き、図5(c)に示すように、口栓本体(100)の注出筒壁(110)内の開封フラップ(140)を指で押圧して押し下げて、積層シートの注出孔予定位置と内面に貼られた封止フィルムとを破断して注出孔を開口する開封機能付口栓(10)が知られている(例えば、特許文献1参照)。なお、押し下げられた開封フラップは、封止フィルムが貼られた積層シートがある程度の厚みと剛性をもつため、開口された注出孔に挟まり、注出孔の開口を維持するものである。

【発明が解決しようとする課題】
しかしながら、上述の従来の開封機能付口栓は、開封フラップを指で押し下げるときに、内容物で指を汚したり、開封フラップが押込み難かったり、押し込まれた開封フラップが外れてきて注出孔の開口部が狭くなったりすることがあった。また、従来の封止フィルムには、バリヤ層として一般にアルミニウム箔層が使用されていたが、このアルミニウム箔層は、酸素や水蒸気などに対するバリヤ性が優れているが、使用後の廃棄物処理として、焼却時に残存滓が残ったり、再利用も難しく、環境保全上に好ましくない問題があった。このため、最近では、ポリエチレンテレフタレートフィルムに酸化ケイ素などの金属や金属酸化物を蒸着させた蒸着フィルムがバリヤ層として使用されるようになった。このバリヤ層に蒸着フィルムを使用した封止フィルムは、従来のバリヤ層にアルミニウム箔を使用した封止フィルムに比較して、破断力を必要とするために、従来の開封機能付口栓の開封フラップ構造では、注出孔予定位置を開口し難かったり、開封フラップの折れ曲がり支線となる注出筒壁内面と接続する薄肉ヒンジの幅が比較的に幅が狭いために、切断してしまうことなどがあった。
【0005】
本発明は、上述の従来の開封機能付口栓の問題を解決したものであり、液体用紙容器のミシン目又は切れ目を入れた注出孔予定位置を、酸化ケイ素などの蒸着フィルムをバリヤ層に用いた封止フィルムで封止されていても、注出孔予定位置を容易に広く開口でき、開口時に指を内容物で汚すことがなく、また、流通過程で誤作動により注出孔予定位置が開口されることがなく、開封後の保管時に開口部が狭くなることのない開封機能付口栓を提供するものである。
【0006】
【課題を解決するための手段】
すなわち、本発明は、口栓本体の後方の注出筒壁に、蓋を薄肉ヒンジを介して開閉可能に接続する箱形状のプラスチック製の口栓であって、口栓本体の底板の前方側に開口部を設け、この開口部上に、前方から後方へ上端水平板と後方下がりの中間傾斜板と下端水平板とが連続し、前記上端水平板と中間傾斜板の外周下面に連続させて開封刃を垂設し、前記下端水平板の後方端縁に左右方向の押し板を立設し、幅が後方へ漸次広くなる平面形状の開封フラップの後方端を、底板の開口部後方側端に薄肉ヒンジを介して接続し、蓋の天板下面に、前記口栓本体の注出筒壁と密接する封止リングと前記口栓本体の開封フラップの押し板の後面と当接する係止兼押し板を垂設したことを特徴とする開封機能付口栓である。
【0007】
【発明の実施の形態】
次に、本発明の開封機能付口栓の実施の形態について、図を用いて詳細に説明する。
図1(a)は、本発明の一実施形態の開封機能付口栓の断面図であり、図1(b)は、その開封フラップを押し下げたときの断面図であり、図1(c)は、開封後、蓋を口栓本体に閉じたときのフラップの状態を示す断面図である。図2は、図1(a)のA部分の拡大断面図である。図3は、図1の開封機能付口栓の平面図で、図4は、その要部の形状を示す説明図である。
【0008】
本実施形態の開封機能付口栓(10)は、図1(a)に示すように、蓋(200)を薄肉ヒンジ(111)を介して、開封機能をもつ口栓本体(100)の注出筒壁(110)の後方に開閉可能に接続し、平面形状が、図3及び図4に示すように、前方に円弧をもつ長方形状で、図1(a)及び図4に示すように、箱状の開封機能付口栓(10)である。そして、この開封機能付口栓は、通常、ヒンジ効果が良好なポリプロピレンのような熱可塑性樹脂を用いて、口栓本体と蓋とを射出成形法により一体に作製するものである。
【0009】
本実施形態の開封機能付口栓(10)の口栓本体(100)の構造は、図1(a)に示すように、底板(120)の前方側に開口部(130)を設け、この開口部上に、前方から後方へ上端水平板(141)と後方下がりの中間傾斜板(142)と下端水平板(143)とが連続し、上端水平板と中間傾斜板の外周下面に連続させて開封刃(145)を垂設し、下端水平板の後方端縁に左右方向の押し板(144)を立設し、図3に示すように、幅が後方へ漸次広くなる平面形状の開封フラップ(140)の後方端を、図1(a)に示すように、底板(120)の開口部(130)後方側端に薄肉ヒンジ(121)を介して接続するものである。
【0010】
そして、蓋(200)の構造は、図1(a)に示すように、天板(210)下面に、口栓本体(100)の注出筒壁(110)と密接する封止リング(211)を垂設し、また、口栓本体の開封フラップ(140)の押し板(144)の後面と当接する係止兼押し板(213)を、封止リング(211)の内側の対応位置の天板(210)下面に、図1(a)、図3及び図4に示すように、左右方向へ垂設するものである。なお、必要に応じては、図2に示すように、蓋(200)の封止リング(211)の前方側の先端部外周面に咬合凸部(212)を設け、口栓本体(100)の前方側の注出筒壁(110)先端部内周面に咬合凹部(112)を設けて取り外し可能に適度にしかりと咬合させてもよい。また、蓋部を開閉し易くするために、蓋部の前方側の先端に開閉用突起を設けてもよい。
【0011】
上述の本実施形態の開封機能付口栓を、液体用紙容器のミシン目又は切れ目を封止フィルムで封止した注出孔予定位置上に、開封部を合わせて下面を接着剤などで接着して立設し、この開封機能付口栓を、図1(b)に示すように、蓋(200)を後方へ薄肉ヒンジ線(111)を支線として回転して開き、口栓本体(100)内の開封フラップ(140)の後方端に立設する押し板(144)を指で前方へ押し倒すと、開封フラップ(140)が、底板(120)と接続する薄肉ヒンジ(121)を支線として下方へ折れ込み、開封フラップ(140)の上端水平板(141)と中間傾斜板(142)の外周下面に垂下する開封刃(145)が、注出孔予定位置のミシン目や下面に貼着する封止フィルムを破断して、容器が開封する。開封フラップは、底板に対してほぼ直角まで折れ込ませるものである。注出孔予定位置の開口操作は、指で開封フラップの押し板を前方へ押し倒すものであり、内容物で指を汚すことがない。また、本実施形態の開封機能付口栓の開封フラップの開封刃は、従来の開封機能付口栓の線状の開封刃とは異なり、図4に示すように、前方より後方へ漸次幅が広がっているため、注出孔予定位置の開口が大きくなる。
【0012】
なお、開封フラップの折れ込みは、押し板だけによらなくてもよく、まず、押し板(144)で、図1(b)に示すように、多少折り込ませ、次に、その状態で、蓋(200)を閉じると、図1(c)に示すように、蓋の天板(210)下面に垂下する係止兼押し板(213)の先端が、開封フラップ(140)の押し板(144)の後面先端部に当接し、開封フラップの押し板を先方へ押し倒し、開封フラップは、底板(120)に対してほぼ直角まで折れ込まれ、注出孔予定位置が開口する。この開口操作は、梃の理を使うため、力をあまり必要としない。
【0013】
また、本実施形態の開封機能付口栓を注出孔予定位置上に突設した液体用紙容器は、未開封のときは、図1(a)に示すように、蓋(200)の天板(210)下面に垂下する係止兼押し板(213)の後面が、口栓本体(100)の開封フラップ(140)の押し板(144)の前面に当接し、開封フラップが下方へ折れ込まれことが係止されている。このため、流通過程での誤作動による注出孔予定位置の開口が防げる。また、開封後に再度蓋をしたときには、図1(c)に示すように、蓋(200)の天板(210)下面に垂下する係止兼押し板(213)の先端が、口栓本体(100)の下方へ折れ込まれた開封フラップ(140)の押し板(144)の後面先端部に当接している。このため、折れ込まれた開封フラップの戻りが阻止され、保管時に注出孔予定位置の開口部が狭くなることがない。
【0014】
また、本実施形態の開封機能付口栓の後方へ幅広の開封フラップを底板に接続する薄肉ヒンジの幅は、従来の開封機能付口栓の後方へ幅狭の開封フラップを注出筒壁に接続する薄肉ヒンジの幅とは異なり、適正な強度があり、ミシン目又切れ目をもつ注出孔予定位置を封止する封止フィルムのバリヤ層に酸化ケイ素などの蒸着フィルムが用いられていても、開封フラップを破断して容易に開口することができる。
【0015】
【発明の効果】
本発明の開封機能付口栓は、開封機能を内蔵する口栓本体の後方に薄肉ヒンジを介して蓋を開閉可能に接続し、熱可塑性樹脂で一体に射出成形したものであり、液体用紙容器のミシン目又は切れ目を入れた注出孔予定位置上に接着して使用すると、注出孔予定位置を、酸化ケイ素などの蒸着フィルムをバリヤ層とする封止フィルムで内面から封止していても、開封フラップで、注出孔予定位置を容易に広く開口でき、開口時に指を内容物で汚すことがなく、流通過程で誤作動により注出孔予定位置が開口されることがなく、また、開封後の保管時に開口部が狭くなることがない。

[Problems to be solved by the invention]
However, the above-mentioned conventional opening function-equipped plug has a problem in that, when the opening flap is pressed down with a finger, the contents are stained with the finger, the opening flap is difficult to push in, or the pushed-in opening flap comes off and the spout hole comes out. The opening sometimes became narrow. In addition, in the conventional sealing film, an aluminum foil layer was generally used as a barrier layer.This aluminum foil layer has an excellent barrier property against oxygen, water vapor, and the like. However, there is a problem that the residual residue remains during incineration and that it is difficult to recycle, which is not preferable in terms of environmental protection. For this reason, recently, a vapor deposition film in which a metal such as silicon oxide or a metal oxide is vapor-deposited on a polyethylene terephthalate film has been used as a barrier layer. This sealing film using a vapor-deposited film for the barrier layer requires a breaking force as compared with the conventional sealing film using an aluminum foil for the barrier layer. In the flap structure, it is difficult to open the expected pouring hole position, and the thin hinge connected to the inner surface of the pouring cylinder wall, which is the bending branch line of the opening flap, is relatively narrow, so it may be cut. was there.
[0005]
The present invention solves the above-mentioned problem of the conventional plug with an opening function, and sets a perforated hole or a cut-out pouring hole expected position of a liquid paper container to a vapor-deposited film such as silicon oxide on a barrier layer. Even if it is sealed with the used sealing film, the expected pouring hole position can be easily opened widely, so that the finger is not stained with the contents at the time of opening, and the pouring hole expected position due to malfunction during the distribution process. The present invention provides a plug with an opening function in which the opening is not opened and the opening is not narrowed during storage after opening.
[0006]
[Means for Solving the Problems]
That is, the present invention relates to a box-shaped plastic plug having a lid connected to be openable and closable via a thin hinge on a pouring cylinder wall behind the plug main body, the front side of a bottom plate of the plug main body. An opening is provided on the opening, and an upper horizontal plate, a lower middle inclined plate and a lower lower horizontal plate are continuous from front to rear, and are connected to the outer peripheral lower surfaces of the upper horizontal plate and the intermediate inclined plate. An opening blade is vertically provided, a left-right pressing plate is erected on the rear edge of the lower horizontal plate, and the rear end of the flat opening flap whose width gradually increases rearward is changed to the opening rear end of the bottom plate. And a sealing ring, which is in close contact with the spout cylinder wall of the plug body, and a stopper that abuts against the rear surface of the push plate of the opening flap of the plug body, on the lower surface of the top plate of the lid. This is a stopper with an opening function, wherein a push plate is vertically provided.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of a plug with an opening function according to the present invention will be described in detail with reference to the drawings.
FIG. 1A is a cross-sectional view of a plug with an opening function according to an embodiment of the present invention, and FIG. 1B is a cross-sectional view when the opening flap is depressed, and FIG. FIG. 4 is a cross-sectional view showing a state of the flap when the lid is closed on the plug body after opening. FIG. 2 is an enlarged cross-sectional view of a portion A in FIG. FIG. 3 is a plan view of the plug with opening function of FIG. 1, and FIG. 4 is an explanatory view showing the shape of the main part thereof.
[0008]
As shown in FIG. 1A, the plug with opening function (10) of the present embodiment has a lid (200) with a thin body hinge (111), and a plug body (100) with opening function. It is connected to the back of the outlet cylinder wall (110) so as to be openable and closable, and has a rectangular shape having a circular arc in front as shown in FIGS. 3 and 4, and as shown in FIGS. And a box-shaped plug with opening function (10). In addition, this plug with an opening function is usually manufactured integrally with a plug main body and a lid by an injection molding method using a thermoplastic resin such as polypropylene having a good hinge effect.
[0009]
As shown in FIG. 1A, the structure of the plug body (100) of the plug with opening function (10) of the present embodiment is provided with an opening (130) on the front side of the bottom plate (120). An upper horizontal plate (141), an intermediate inclined plate (142) and a lower horizontal plate (143) descending from the front continue from the front to the rear on the opening, and are connected to the outer peripheral lower surfaces of the upper horizontal plate and the intermediate inclined plate. The opening blade (145) is vertically extended, and a push plate (144) in the left-right direction is erected on the rear edge of the lower horizontal plate, and as shown in FIG. As shown in FIG. 1A, the rear end of the flap (140) is connected to the rear end of the opening (130) of the bottom plate (120) via a thin hinge (121).
[0010]
Then, as shown in FIG. 1A, the structure of the lid (200) is such that a sealing ring (211) is provided on the lower surface of the top plate (210) to be in close contact with the pouring cylinder wall (110) of the plug body (100). ), And the locking / push plate (213) which comes into contact with the rear surface of the push plate (144) of the opening flap (140) of the plug body is attached to the corresponding position inside the sealing ring (211). As shown in FIG. 1A, FIG. 3 and FIG. 4, on the lower surface of the top plate (210), it is vertically suspended in the left-right direction. If necessary, as shown in FIG. 2, an occlusal projection (212) is provided on the outer peripheral surface of the front end of the sealing ring (211) of the lid (200), and the plug body (100) is provided. An occlusal concave portion (112) may be provided on the inner peripheral surface of the tip of the injection cylinder wall (110) on the front side of the diaper, so that the dent bite can be appropriately and removably engaged. Further, in order to easily open and close the lid, an opening / closing protrusion may be provided at a front end of the lid.
[0011]
The opening function-equipped stopper of the above-described embodiment is bonded to the opening of the liquid paper container at the expected pouring hole where the perforations or cuts are sealed with a sealing film, and the lower surface thereof is bonded with an adhesive or the like. As shown in FIG. 1 (b), the plug with opening function is opened by rotating the lid (200) backward with the thin hinge line (111) as a branch line, and the plug body (100). When the push plate (144) erected at the rear end of the inside opening flap (140) is pushed down with a finger forward, the opening flap (140) is moved downward with the thin hinge (121) connected to the bottom plate (120) as a branch line. An opening blade (145) hanging on the upper horizontal plate (141) of the opening flap (140) and the outer peripheral lower surface of the intermediate inclined plate (142) is attached to the perforation or the lower surface at the expected pouring hole position. The sealing film is broken and the container is opened. The opening flap is to be folded almost at right angles to the bottom plate. The opening operation at the expected pouring hole position is to push down the push plate of the opening flap forward with a finger, and does not stain the finger with the contents. In addition, unlike the linear opening blade of the conventional opening function-equipped stopper, the opening blade of the opening flap of the opening function-equipped stopper of the present embodiment has a gradually increasing width from the front to the rear as shown in FIG. Because of the widening, the opening at the expected pouring hole becomes large.
[0012]
The folding of the opening flap does not need to be performed only by the push plate. First, the push flap (144) is slightly folded as shown in FIG. 1 (b). When (200) is closed, as shown in FIG. 1 (c), the tip of the locking and pushing plate (213) hanging on the lower surface of the top plate (210) of the lid is pushed by the pushing plate (144) of the opening flap (140). A) The pushing plate of the opening flap is pushed down to the front, and the opening flap is bent substantially at right angles to the bottom plate (120) to open the expected pouring hole position. This opening operation requires little force because it uses leverage.
[0013]
In addition, when the liquid paper container having the opening function-provided plug of the present embodiment protruding above the expected pouring hole position is not opened, the top plate of the lid (200) is opened as shown in FIG. (210) The rear surface of the locking and pushing plate (213) hanging on the lower surface abuts against the front surface of the pushing plate (144) of the opening flap (140) of the plug body (100), and the opening flap is folded downward. Rare things are locked. For this reason, it is possible to prevent the opening of the pouring hole scheduled position due to a malfunction during the distribution process. When the lid is closed again after opening, as shown in FIG. 1C, the tip of the locking and pushing plate (213) hanging on the lower surface of the top plate (210) of the lid (200) is connected to the plug body ( 100) is in contact with the front end of the rear surface of the push plate (144) of the opening flap (140) folded downward. Therefore, the folded open flap is prevented from returning, and the opening at the expected pouring hole position during storage is not narrowed.
[0014]
Also, the width of the thin hinge connecting the wide opening flap to the bottom plate behind the opening function-equipped plug of the present embodiment is such that the narrow opening flap behind the conventional opening function-equipped plug is attached to the spout cylinder wall. Unlike the width of the thin hinge to be connected, it has appropriate strength, and even if a vapor deposition film such as silicon oxide is used for the barrier layer of the sealing film that seals the expected position of the perforated hole with the perforations or cuts. The opening flap can be broken to open easily.
[0015]
【The invention's effect】
The plug with an opening function of the present invention is a liquid paper container in which a lid is openably and closably connected to the back of a plug body having a built-in opening function via a thin hinge, and is integrally molded with a thermoplastic resin. When used by bonding on the perforated hole or the perforated pouring hole planned position, the pouring hole planned position is sealed from the inner surface with a sealing film having a vapor deposited film such as silicon oxide as a barrier layer. Also, with the opening flap, the expected pouring hole position can be easily opened widely, the finger is not stained with the contents at the time of opening, and the pouring hole planned position is not opened due to malfunction during the distribution process, and The opening does not become narrow during storage after opening.
