Description
本発明は、果汁、お茶、食用油、醤油、ドレッシング、つゆ、だし、たれ、味醂、酢、液体香辛料等の液体を収納する容器に用いられ、容器本体と口栓が別の材料で製造されるので、廃棄処理する場合、分別する必要がある為、容易に分離が可能で、かつ、開封の有無を容易に判別がつく打栓口栓に関する。 The present invention is used in containers for storing liquids such as fruit juice, tea, edible oil, soy sauce, dressing, soy sauce, dashi, sauce, miso, vinegar, liquid spices, etc. Therefore, the present invention relates to a stopper plug that can be easily separated and can be easily discriminated whether or not it is opened because it needs to be separated when it is disposed of.
近年、液体用容器本体の材料としては、ポリエチレンテレフタレート樹脂やガラス瓶が主に用いられる。しかし、これに用いられる口栓は、ポリプロピレンやポリエチレン、ポリオキシペンテン等のオレフィン系樹脂や、アクリロニトリルブタジエンスチレン樹脂やアクリロニトリルスチレン樹脂などのスチレン系樹脂が用いられている。このように、容器本体と、口栓との使用樹脂は異なっている場合がほとんどである。 In recent years, polyethylene terephthalate resin and glass bottles are mainly used as materials for liquid containers. However, as the stopper used for this, olefin resins such as polypropylene, polyethylene, and polyoxypentene, and styrene resins such as acrylonitrile butadiene styrene resin and acrylonitrile styrene resin are used. Thus, in most cases, the resin used for the container body and the plug is different.
例えば、醤油の容器本体はポリエチレンテレフタレート樹脂であるが、口栓はポリエチレンであり、ドレッシングの容器本体はポリエチレンテレフタレート樹脂やガラス瓶であるが、口栓はポリエチレン、キャップはポリプロピレンである。このように、容器本体と、口栓との使用樹脂は異なっている場合がほとんどである。それは、ガラスやポリエチレンテレフタレートの容器本体は、内容物の保存性能が高く、量産性も高いが、それで製造した場合、口部は肉厚が厚い事もあり、この口部の寸法精度が非常に低い。その為、嵌合する口栓は、柔軟性がある樹脂で製造し、それを打栓等により押し込んで嵌合する事で、確実に容器と口栓の隙間を埋め、密封性を確保していた。又、ポリプロピレンのような結晶性の樹脂は、薄肉にして分子方向を合わせてできるヒンジが容易にできて、生産性が高く、口栓とキャップが一度に作成できるメリットも大きい。このようにして、使用材料は、容器本体と口栓との使用樹脂が異なった組み合わせで設計されて来た背景がある。
以上のような材質の選定によって、容器本体と口栓の材質を異なって製造される容器ではあるが、この容器の内容物を使い切り、容器を廃棄する場合、材料の違いから、各自治体の多くでは、分離して材料別に分別して廃棄するよう指導が行われている。
For example, the container body of soy sauce is polyethylene terephthalate resin, but the stopper is polyethylene, and the container body of dressing is polyethylene terephthalate resin or a glass bottle, but the stopper is polyethylene and the cap is polypropylene. Thus, in most cases, the resin used for the container body and the plug is different. The container body of glass or polyethylene terephthalate has high storage performance and high mass productivity, but when manufactured with it, the mouth may be thick and the dimensional accuracy of the mouth is very high. Low. For this reason, the plugs to be fitted are made of a flexible resin, and they are pushed in with a stopper to fit them to ensure that the gap between the container and the plug is filled. It was. In addition, a crystalline resin such as polypropylene can easily form a hinge that can be thinly aligned with the molecular direction, has high productivity, and has a great merit that a stopper and a cap can be formed at a time. Thus, there is a background that the material used has been designed with different combinations of the resin used for the container body and the stopper.
Although the container is manufactured with different materials for the container body and the cap by selecting the materials as described above, when the contents of the container are used up and the container is discarded, there are many local governments due to the difference in materials. Then, it is instructed to separate and sort by material.
ところで、近年、毒物混入など、犯罪防止の為、開封の有無を判別できるように、開封状態では、主に下記のように設計されている。
すなわち、ネジ式では、口栓の袴部分が開封時に切れて、容器の鍔下部分に残るように設計されている。また、打栓式では、口栓の容器鍔下の首部分に口栓本体が嵌合されて残り、開封の有無を判別できる。
このように、開封しても、口栓の一部を容器本体から簡単には外せない構造を作り、開封の有無が明確にする方法が採られていた。
その為、これを分離して材料別に分別できるようにする事は、カッター等の道具が必要であり、子供やお年寄りにとっては、使用材料別になるよう分離する事は面倒であり、怪我をする恐れもあった。
By the way, in recent years, the following design is mainly performed in the opened state so that the presence or absence of opening can be determined for the prevention of crime such as poisoning.
That is, the screw type is designed so that the hook part of the spout is cut when opened and remains in the lower part of the container. Further, in the plugging type, the plug main body remains fitted to the neck portion of the cap under the container arm, and it can be determined whether or not the bottle is opened.
Thus, a method has been adopted in which a part of the stopper is not easily removed from the container body even after opening, and the presence or absence of opening is clarified.
For this reason, it is necessary to use tools such as cutters to separate them according to their materials. For children and the elderly, separating them according to the materials used is troublesome and injured. There was also fear.
文献１では、キャップ本体とヒンジで結合した蓋体のヒンジ反対側に有するフランジの
先端下面に係止突起を起立設すると共に、キャップ本体の円弧状外周面上端縁に薄肉部を介してフランジ先端部に外側から対向位置すべく連設した円弧状の係合片に係止突起を乗り越えて内側から係止する係合凸起を設けた。そして、肉薄部による係合片のキャップ本体に対する連結を少なくとも係合片の両側端部と中央とで達成してなる不正開封防止ヒンジキャップを提案している。
しかし、このキャップは、キャップ本体と係合片止部が繋がっていた薄肉部の破断でしか、判断できない。もしこの係合片が薄肉でしか繋がっていないので、開封前は係合片止部が繋がっていた事を知らなかった場合は、開封しているか判断が着かない問題がある。
In Document 1, a locking projection is erected on the lower surface of the front end of the flange on the side opposite to the hinge of the lid body that is coupled to the cap main body by a hinge, and the front end of the flange is inserted into the upper end edge of the arc-shaped outer peripheral surface of the cap main body via a thin portion. Engagement protrusions are provided on the arc-shaped engagement pieces that are arranged so as to be opposed to each other from the outside, over the locking projections and locked from the inside. And the tamper-evident prevention hinge cap which achieves the connection with the cap main body of the engagement piece by the thin part at least by the both ends and center of the engagement piece is proposed.
However, this cap can be judged only by the breakage of the thin portion where the cap main body and the engaging piece stop portion are connected. If this engagement piece is connected only with a thin wall, if it is not known that the engagement piece stopper is connected before opening, there is a problem that it cannot be determined whether the engagement piece is opened.
文献２では、容器本体と打栓方式で勘合するヒンジキャップで、キャップ本体の下端からキャップ本体のスカート部を覆って延びる側壁が形成され、該側壁はヒンジ部を介して上蓋と連結されると共に、スカート部との間に互いに係合する係合部が形成されており、該側壁で覆われるキャップ本体のスカート部の係合部の内側で且つ側壁とキャップ本体との連結部の両側に弱化部が形成されて、上蓋をキャップ本体から開蓋し、該側壁の係合部を解除して、上蓋をキャップ軸方向上方に引き上げることにより、キャップ本体のスカート部に形成された弱化部が破壊され、容器口部から容易に取り外す事が可能なキャップである。
このキャップは、容器口部からキャップを外す時、上蓋を引き上げて、側壁の係合部を解除するので、ヒンジの部分を介して引っ張る行為にならざるを得ない。その為、ヒンジを中心に上蓋を回転して開閉する場合は耐久性もあるヒンジであっても、引っ張られ、弱化部を破壊する力が、ヒンジにも直接係ることになる。その為、使用されてすでに伸ばされかかったヒンジ部の方が、弱化部よりも弱かったりするケースが多くなり、ヒンジが先に破壊されてしまうケースが多々発生する問題がある。その場合、弱化部を破壊するには、持つ所が無くなっているので、カッターなどを使用するなど、面倒な作業になってしまう問題があった。
In Document 2, a hinge cap that fits into the container body in a stoppering manner has a side wall that extends from the lower end of the cap body to cover the skirt portion of the cap body, and the side wall is connected to the upper lid via the hinge portion. An engagement portion that engages with each other is formed between the skirt portion, and is weakened inside the engagement portion of the skirt portion of the cap body covered with the side wall and on both sides of the connection portion between the side wall and the cap body. Is formed, the upper lid is opened from the cap body, the engagement portion of the side wall is released, and the upper lid is pulled upward in the cap axial direction, so that the weakened portion formed in the skirt portion of the cap body is destroyed. The cap can be easily removed from the container mouth.
When the cap is removed from the container mouth portion, the upper lid is pulled up to release the engaging portion of the side wall, so that the cap must be pulled through the hinge portion. Therefore, when opening and closing by rotating the upper lid around the hinge, even if it is a durable hinge, the force that is pulled and destroys the weakened portion also directly affects the hinge. For this reason, the hinge portion that has been used and has already been stretched is more likely to be weaker than the weakened portion, and there is a problem that the hinge is often destroyed first. In that case, there is no place to hold the weakened part, so there is a problem that it becomes troublesome work such as using a cutter.
文献３は、容器本体と打栓方式で嵌合するヒンジキャップである。キャップ本体の下端からキャップ本体の上端から下方に向かって延びているスリットにより内側側壁と外側側壁に分割され、内側側壁と外側側壁とは、該スリット部分で互いに対面しているが、下方部分及び両側部分では一体に連なっているヒンジキャップである。
このキャップも、ヒンジ構造の下に、外の部分と内の部分を設ける事により、金型での薄い部分形成された所が出来て、金型の冷却が困難な状況から、射出成形の成形サイクルが長くなり、コストアップの状態になる問題や、キャップの開閉を乱暴に行うと、脆弱部を切断してしまう可能性がある問題や、肉厚の薄いヒンジ下の内外構造部に脆弱部を設けているので、射出成形時に、ショートショットが起こりやすく、成形条件や成形樹脂の選定が限定され、使用樹脂範囲がせまくなる問題は同じように存在している。
Document 3 is a hinge cap that fits into a container body by a stoppering method. It is divided into an inner side wall and an outer side wall by a slit extending downward from the upper end of the cap body from the lower end of the cap body, and the inner side wall and the outer side wall face each other at the slit portion. It is a hinge cap that is continuous with both sides.
This cap also has an outer part and an inner part under the hinge structure, so that a thin part can be formed in the mold, making it difficult to cool the mold. The problem is that the cycle becomes longer and the cost is increased, the problem that the fragile part may be cut if the cap is opened and closed roughly, and the fragile part in the inner and outer structural parts under the thin hinge Therefore, there is a similar problem that short shots are likely to occur during injection molding, the molding conditions and the selection of molding resin are limited, and the range of resin used is constrained.
上記問題に鑑みて、誰でも開封前と開封後の区別がつき、特にキャップを開けない状態でも、開封の有無を確認できる、バージン性を担保できる構造を有する口栓で、かつ、価格の上昇を招かない口栓である。
また、口栓と容器本体を分離するのに、分りやすく、失敗しにくく、手間を掛けないで解体できる口栓である事が、本明の課題である。
In view of the above problem, anyone can distinguish between before opening and after opening, especially in the state where the cap can be opened even if the cap is not opened, and it has a structure that can ensure virginity, and the price rises It is a spout that does not invite
In addition, it is an object of the present invention to be a plug that is easy to understand, difficult to fail, and can be disassembled without taking effort to separate the plug from the container body.

ヒンジはダブルヒンジになっていて、中央のバネヒンジ５１と、左右のヒンジ５２から構成された図になっているが、このダブルヒンジは、図示したミラーヒンジだけではなく、バタフライヒンジなど他の３点ヒンジであっても、又、単に通常のひとつのヒンジから構成されるヒンジであってもかまわない。
なお、天板部９の内部やその液漏れ防止等に基づく構造は、異なっていてもかまわない。キャップ側にも、キャップインナーリング４１１があるが、口栓本体側の形状に合わせたものであれば、コンタクトリングがなくても、他の方式でもかまわない。
The hinge is a double hinge, and is composed of a central spring hinge 51 and left and right hinges 52. This double hinge is not only the mirror hinge shown, but also other three points such as a butterfly hinge. It may be a hinge, or may be a hinge composed of only one normal hinge.
In addition, the structure based on the inside of the top-plate part 9, its liquid leakage prevention, etc. may be different. There is also a cap inner ring 411 on the cap side, but there is no need for a contact ring as long as it matches the shape of the cap body side, and other methods may be used.
キャップ４は、キャップ天板４１とキャップ側壁４２からなり、天板４１にはキャップインナーリング４１１が設けられ、キャップ側壁４２にはフランジ４２１とその下面に挿嵌片４２２がブリッジ４２３によって連結されている。フランジ４２１は、ブリッジ４２３を破断するのに、ブリッジを引き上げる力で破断させるので、破断する力が出しやすいように、ブリッジ４２３の根元に、指が掛かりやすいように設ける。そして、挿嵌片４２２には先端に挿嵌爪４２２１が設けられ、挿嵌壁８２の開口部８１に挿嵌し、一度挿入された挿嵌片４２２が完全に挿嵌孔８から抜け出ないようにしている。 The cap 4 includes a cap top plate 41 and a cap side wall 42. The top plate 41 is provided with a cap inner ring 411. The cap side wall 42 has a flange 421 and an insertion piece 422 connected to the lower surface thereof by a bridge 423. Yes. The flange 421 breaks the bridge 423 with a force for pulling up the bridge. Therefore, the flange 421 is provided so that a finger can be easily applied to the base of the bridge 423 so that the breaking force is easily generated. An insertion claw 4221 is provided at the tip of the insertion piece 422 and is inserted into the opening 81 of the insertion wall 82 so that the insertion piece 422 once inserted does not completely come out of the insertion hole 8. I have to.
図６は、キャップ４を閉めかけている状態で、図７、図８は、キャップ４を閉め終えた状態を示している。この状態で容器本体２に打栓口栓を打栓して、嵌合する。
キャップ４を閉めると、挿嵌片４２２は挿嵌孔８に入り込まれるが、挿嵌爪４２２１は挿嵌壁８２に設けられた開口部８１の下端に嵌合し、抜けられないようになる。また、挿嵌爪４２２１の上側の嵌合片表面４２２２は、挿嵌壁８２で隠れ、見えない状態にする。従って、開口部８１上側の側面壁８２高さは、挿嵌片表面４２２２の高さとブリッジ４２１の高さの合計にしておく。
フランジ４２１にブリッジ４２３で連結された挿嵌片４２２先端の側面に、挿嵌爪４２２１が設けられている。他方、挿嵌孔８の外側に膨らんだ挿嵌壁８２があり、その中央下側には開口部８１が設けられ、キャップを閉めた時、挿嵌爪４２２１がこの開口部８１に嵌まり、挿嵌片４２２は挿嵌孔から抜け出せない。
口栓本体３の凸設リング９７には嵌合突起９７１が設けられ、それに対応して、キャップ側は、フランジ４２１の根元近傍のキャップ側壁４２に嵌合凹部４２４が設けられ、挿嵌片４２２が挿嵌孔７２に入り込んで、ブリッジ４２３が離れた後でも、キャップ４が口栓本体３に嵌合して固定できるように設計されている。
この嵌合突起９７１や嵌合凹部４２４は、全周囲に設けてもかまわないが、本図面では、挿嵌部近傍に設けた例を示した。
6 shows a state where the cap 4 is being closed, and FIGS. 7 and 8 show a state where the cap 4 has been closed. In this state, a stopper plug is plugged into the container body 2 and fitted.
When the cap 4 is closed, the insertion piece 422 is inserted into the insertion hole 8, but the insertion claw 4221 is fitted to the lower end of the opening 81 provided in the insertion wall 82 and cannot be removed. Further, the fitting piece surface 4222 on the upper side of the insertion claw 4221 is hidden by the insertion wall 82 so as not to be seen. Therefore, the height of the side wall 82 on the upper side of the opening 81 is the sum of the height of the insertion piece surface 4222 and the height of the bridge 421.
An insertion claw 4221 is provided on the side surface of the distal end of the insertion piece 422 connected to the flange 421 by the bridge 423. On the other hand, there is an insertion wall 82 that swells outside the insertion hole 8, and an opening 81 is provided on the lower side of the center. When the cap is closed, the insertion claw 4221 is fitted into the opening 81, The insertion piece 422 cannot be removed from the insertion hole.
The protrusion ring 97 of the plug body 3 is provided with a fitting protrusion 971. Correspondingly, on the cap side, a fitting recess 424 is provided in the cap side wall 42 near the base of the flange 421, and the insertion piece 422 is provided. Is inserted into the insertion hole 72 and the cap 4 can be fitted and fixed to the plug body 3 even after the bridge 423 is separated.
The fitting protrusion 971 and the fitting recess 424 may be provided around the entire periphery, but in the present drawing, an example in which the fitting protrusion 971 and the fitting recess 424 are provided in the vicinity of the insertion portion is shown.
図９は、図８のように閉じたキャップ４を、再度開こうとしている状態で、キャップを開こうとすると、挿嵌孔８の開口部８１上端に嵌合した挿嵌爪４２２１が引っかかって抜けず、その為、ブリッジ４２３部分が破断し、挿嵌片４２２は挿嵌孔８における下端の隙間８４に落下する。 9 shows that when the cap is opened again when the closed cap 4 is opened again as shown in FIG. 8, the insertion claw 4221 fitted to the upper end of the opening 81 of the insertion hole 8 is caught. Therefore, the bridge 423 portion is broken, and the insertion piece 422 falls into the gap 84 at the lower end of the insertion hole 8.
次に、図１０、図１１、図１２で示すように、キャップ４と挿嵌片４２２は分離し、挿嵌片４２２は挿嵌孔８の下端の隙間８４に落下する。すると、今まで隠された挿嵌片４２２の挿嵌片表面４２２２が開口部８１から見えるようになる。
図１３で示すように、挿嵌片表面４２２２には彫刻で「開封」、「済」「開」といったような文字や記号などを彫刻したり、口栓本体の色と違えて、色入れや印刷、箔押しなど、又はそれらを組み合わせて、一度開封された事が明確に示す事が出来る。
その為、この容器のバージン性が失われた事が表明され、キャップを開けなくても、開封した事を明確に分りやすく表示され、明確に分るようになる。
Next, as shown in FIGS. 10, 11, and 12, the cap 4 and the insertion piece 422 are separated, and the insertion piece 422 falls into the gap 84 at the lower end of the insertion hole 8. Then, the insertion piece surface 4222 of the insertion piece 422 that has been hidden until now can be seen from the opening 81.
As shown in FIG. 13, the insertion piece surface 4222 is engraved with characters and symbols such as “opened”, “finished” and “opened” by engraving, and different from the color of the plug body, Printing, foil stamping, etc., or a combination of them, can clearly show that it has been opened once.
For this reason, it is announced that the virginity of the container has been lost, and even if the cap is not opened, the fact that the container has been opened is clearly displayed and can be clearly understood.
従って、再度このキャップを閉めた状態では、図１１のように、挿嵌片の挿嵌表面４２２２が開封の表記を明示するようになる。
また、このように、挿嵌片が外れた後でも、図１２に示すように、キャップ４は嵌合凹部４２４が嵌合突起９７１と嵌合する為、閉じて固定できるので、問題は出ない。
挿嵌片４２２は、図１３で示すように、挿嵌爪４２２１は挿嵌片４２２の幅よりも小さな幅で設計され、挿嵌片表面４２２２には開封などの彫刻と色入れなどが施される。挿嵌爪４２２１の幅を狭くするのは、挿嵌孔８は挿嵌爪４２２１が挿入される時の厚みよりも、孔の縦幅８０１が確実に狭く、無理嵌合で挿入される為、挿嵌壁８２が変形して通り易くする為である。このようにする事で、挿嵌壁８２は中央の下端に開口している事もあり、中央がいくらかフリー状態になっているので、挿嵌爪４２２１の厚み分を変形させ、挿嵌できる。
もちろん、挿嵌片４２２の挿入側端面には角を取ったり丸めたりして、挿入しやすくしておく事が望ましい。挿嵌孔８の内面角も、丸めて、破損しにくいようにしておく事が好ましい。
また、ブリッジ４２３は、フランジ側で切断される事が好ましいので、フランジ側の太さを細くしたり、反対側の挿嵌片側に丸みを付けたりしておくなどの対策を採っておく事が望ましい。
また、挿嵌片４２２が開口部８１よりも充分大きく、開口部８１から抜け落ちないような大きさにしておく必要がある。
本発明の打栓口栓は、以上のようなものである。
Therefore, when the cap is closed again, as shown in FIG. 11, the insertion surface 4222 of the insertion piece clearly shows the notation of opening.
In addition, even after the insertion piece is removed as described above, the cap 4 can be closed and fixed because the fitting recess 424 is fitted with the fitting protrusion 971 as shown in FIG. .
As shown in FIG. 13, the insertion piece 422 is designed to have a width smaller than that of the insertion piece 422, and the insertion piece surface 4222 is engraved and colored, etc. The The width of the insertion claw 4221 is narrowed because the insertion hole 8 is surely narrower in the vertical width 801 of the hole than the thickness when the insertion claw 4221 is inserted, and is inserted by forced fitting. This is because the insertion wall 82 is deformed to facilitate passage. By doing in this way, since the insertion wall 82 may open to the lower end of the center and the center is in a somewhat free state, the thickness of the insertion claw 4221 can be deformed and inserted.
Of course, it is desirable that the insertion-side end surface of the insertion piece 422 be rounded or rounded to facilitate insertion. It is preferable that the inner surface angle of the insertion hole 8 is also rounded so that it is not easily damaged.
Moreover, since it is preferable that the bridge 423 is cut at the flange side, measures such as reducing the thickness of the flange side or rounding the opposite insertion piece side may be taken. desirable.
In addition, it is necessary that the insertion piece 422 is sufficiently larger than the opening 81 so that the insertion piece 422 does not fall out of the opening 81.
The stopper plug of the present invention is as described above.

図１９、図２０は、キャップ４を閉めた状態を示している。この状態で容器本体２に打栓口栓を打栓して、嵌合する。
挿嵌片４２２は挿嵌孔８との関係は、図７、図８で示したものと同様である。
図２０で示すように、筒状側壁７と天板部９との境には、天板側脆弱部３１が設けられている。図２０では外側から肉を盗んだ脆弱部になっているが、コンタクトリング９６を避ければ、内側から盗んだ天板側脆弱部３１も可能である。この天板側脆弱部３１は、筒状側壁７と天板部９との境全周の半分以上を脆弱部にする事が好ましい。脆弱部が境全周の半分以上であると、嵌合突起７４がその突起分を周方向で抜けて、簡単に容器本体２口元２１から打栓口栓１が抜けやすくなる。
19 and 20 show a state in which the cap 4 is closed. In this state, a stopper plug is plugged into the container body 2 and fitted.
The relationship between the insertion piece 422 and the insertion hole 8 is the same as that shown in FIGS.
As shown in FIG. 20, a top plate-side weakened portion 31 is provided at the boundary between the cylindrical side wall 7 and the top plate portion 9. In FIG. 20, the fragile portion steals meat from the outside, but if the contact ring 96 is avoided, the top plate-side fragile portion 31 stolen from the inside is also possible. It is preferable that the top plate-side fragile portion 31 has a fragile portion at least half of the entire circumference of the boundary between the cylindrical side wall 7 and the top plate portion 9. If the fragile portion is more than half of the entire perimeter, the fitting projection 74 can be removed from the projection in the circumferential direction, and the stopper plug 1 can be easily removed from the container body 2 mouth 21.
図２１は、図１９のように閉じたキャップを、再度キャップ４を開こうとしている状態で、図９と同様、キャップを開こうとすると、挿嵌孔８の開口部８１上端に嵌合した挿嵌爪４２２１が抜けず、その為、ブリッジ４２３部分が破断し、挿嵌片４２２は挿嵌孔８における下端の隙間８４に落下する。 FIG. 21 shows that the closed cap as shown in FIG. 19 is fitted to the upper end of the opening 81 of the insertion hole 8 when the cap is opened as in FIG. 9 while the cap 4 is being opened again. The insertion claw 4221 cannot be removed, so that the bridge 423 portion is broken and the insertion piece 422 falls into the gap 84 at the lower end of the insertion hole 8.
次に、図２２、図２３、図２４で示すように、キャップ４と挿嵌片４２２は分離し、挿嵌片４２２は挿嵌孔８の下端の隙間８４に落下する。すると、今まで隠された挿嵌片４２２の挿嵌片表面４２２２が開口部８１から見えるようになる。
挿嵌片表面４２２２には彫刻で「開封」、「済」「開」といったような文字や記号などを彫刻したり、口栓本体の色と違えて、色入れや印刷、箔押しなど、又はそれらを組み合わせて、一度開封された事が明確に示す事が出来る。
その為、この容器のバージン性が失われた事が表明され、キャップを開けなくても、開封した事を明確に分りやすく表示され、明確に分るようになる。
Next, as shown in FIGS. 22, 23, and 24, the cap 4 and the insertion piece 422 are separated, and the insertion piece 422 falls into the gap 84 at the lower end of the insertion hole 8. Then, the insertion piece surface 4222 of the insertion piece 422 that has been hidden until now can be seen from the opening 81.
The insertion piece surface 4222 may be engraved with characters or symbols such as “opened”, “finished”, “opened” by engraving, color-filling, printing, foil stamping, etc. You can clearly show that it has been opened once.
For this reason, it is announced that the virginity of the container has been lost, and even if the cap is not opened, the fact that the container has been opened is clearly displayed and can be clearly understood.
従って、再度このキャップを閉めた状態では、図２４のように、挿嵌片の挿嵌表面４２２２が開封の表記を明示するようになる。
また、このように、挿嵌片が外れた後でも、キャップ４は嵌合凹部４２４が嵌合突起９７１と嵌合する為、閉じて固定できるので、問題は出ない。
Therefore, when the cap is closed again, as shown in FIG. 24, the insertion surface 4222 of the insertion piece clearly shows the notation of opening.
Further, even after the insertion piece is removed as described above, the cap 4 can be closed and fixed because the fitting recess 424 is fitted with the fitting protrusion 971, so that there is no problem.
一度開封した容器は、通常の使用では、図１０、図２５のように嵌合している。
プラスチックの容器などにおいて、使用材料を節約する為、胴部の肉厚を減らした事で、容器本体の座屈強度が小さい場合は、図１に示すように、口元２１の根元に鍔２２を設け、打栓圧力を受けられるようにしておく。
容器本体２の口元２１の外側全周囲に嵌合する口元突起２１１が設けられ、打栓口栓側の嵌合突起７４と嵌合し、口元内面壁はボトルインナーリング９５とコンタクトリング９６が嵌合している。このことで、容器本体２と打栓口栓１が嵌合し、液留めを確実にできるようにしている。
Once opened, the container is fitted as shown in FIGS. 10 and 25 in normal use.
In a plastic container or the like, if the buckling strength of the container body is small by reducing the thickness of the body part in order to save the material used, as shown in FIG. It should be provided so that it can receive the stoppering pressure.
Mouth projections 211 that fit around the outer periphery of the mouth 21 of the container body 2 are provided, and are fitted with fitting projections 74 on the stopper plug side, and an inner wall of the mouth is fitted with a bottle inner ring 95 and a contact ring 96. Match. By this, the container main body 2 and the stopper plug 1 are fitted, so that the liquid can be surely secured.
容器の内容物を使い終わり、容器や打栓口栓を廃棄する時は、打栓口栓１と容器本体２とは材料が異なる場合が多いので、口栓と容器本体を分解し、分けて各々の材料別に廃棄するようにする。図１５の破線は、本発明の打栓口栓の脆弱部を示している。すなわち、口栓本体３の天板部６と筒状側壁７との境の天板側脆弱部３１と、筒状側壁７における凹部７１左右の凹部側脆弱部３２を設けている。天板側脆弱部３１は、口栓本体の天板部９と筒状側壁７との境の内、凹部７１近傍を含む半分以上を脆弱部にする。半分以上脆弱部にすると、嵌合している容器本体２の口元突起２１１と嵌合突起７４との嵌合部分の残りがすり抜けるように、口栓全体が変形してずれ、抵抗がほとんど無く、口栓を抜く事ができる。凹部側脆弱部３２は、図１８の（１８ａ）で示したように、凹部外側の開口幅より
小さめにして、脆弱部を破断させる力に抵抗が無い様にするか，（１８ｂ）、（１８ｃ）のように、凹部外側に脆弱部を設けて、係合には問題が出にくいようにする。
When you are done using the contents of the container and discard the container or stopper plug, the stopper plug 1 and container body 2 are often made of different materials. Dispose of each material separately. The broken line of FIG. 15 has shown the weak part of the stopper plug of this invention. That is, the top plate side weak part 31 at the boundary between the top plate part 6 and the cylindrical side wall 7 of the plug body 3 and the concave part side weak parts 32 on the left and right sides of the concave part 71 in the cylindrical side wall 7 are provided. The top plate-side fragile portion 31 makes more than half of the boundary between the top plate portion 9 and the cylindrical side wall 7 of the plug main body including the vicinity of the recess 71 a fragile portion. When the fragile part is more than half, the entire plug is deformed and displaced so that the rest of the fitting part between the mouth projection 211 and the fitting protrusion 74 of the container body 2 that is fitted slips through, and there is almost no resistance. You can unplug the spout. As shown in FIG. 18 (18a), the recess-side fragile portion 32 is made smaller than the opening width outside the recess so that there is no resistance to the force to break the fragile portion, or (18b), (18c). ), A fragile portion is provided on the outer side of the concave portion so that it is difficult to cause a problem in engagement.
口栓と容器本体を分解は、図２６〜図３１の順で行われる。
まず、図２６、図２７で示すように、帯部６の係合孔６１と係合爪７１１の係合を外し、帯部６を凹部７１から外す。さらに、図２８、図２９で示すように、帯部を外側に引き出す事で、凹部側脆弱部３２を切断する。
次に、図３０で、天板部９を引き上げることで、天板側脆弱部３１を破断し始め、さらに天板部９を引き上げ、口栓本体の天板部９と筒状側壁７との境の内、凹部近傍を含む半分近くまで破断させていく。ここまで天板側脆弱部が破断すると、嵌合突起７４が容器口元の突起２１１から抜けながら、図３１のように、ボトルインナーリング９５も容器口元２１から抜けて、打栓口栓１を容器本体２から分離する事ができる。
このように凹部７１の左右それぞれの２箇所が脆弱部で構成されている事で、容易に段階的に分解が可能であり、また、口栓を容器の口元に打栓する時、圧縮する力になるので、破損しないで嵌合ができる。
The mouth plug and the container body are disassembled in the order shown in FIGS.
First, as shown in FIGS. 26 and 27, the engagement between the engagement hole 61 of the band 6 and the engagement claw 711 is disengaged, and the band 6 is removed from the recess 71. Furthermore, as shown in FIG. 28 and FIG. 29, the recessed part weak part 32 is cut | disconnected by pulling out a belt | band | zone part outside.
Next, in FIG. 30, by pulling up the top plate portion 9, the top plate-side fragile portion 31 begins to break, and the top plate portion 9 is further lifted, and the top plate portion 9 of the plug body and the cylindrical side wall 7 Break to almost half of the boundary including the vicinity of the recess. When the fragile portion on the top plate side is broken so far, the fitting projection 74 is detached from the projection 211 at the container mouth, and the bottle inner ring 95 is also detached from the container mouth 21 as shown in FIG. It can be separated from the main body 2.
As described above, the left and right portions of the recess 71 are each composed of a fragile portion, so that it can be easily disassembled step by step, and the compression force when the stopper is put into the mouth of the container. Therefore, it can be fitted without breaking.
本発明の打栓口栓を製造するには、射出成形で行う。第２ヒンジ５１，第１ヒンジ５３のヒンジ２箇所に、ブリッジ４２３や、注出口脆弱部９８、天板側脆弱部３１、凹部側脆弱部３２など、薄肉部分が多く成形しづらいが、図１６のように第１ゲート１１、第２ゲート１２のように多点ゲートで成形する事で、樹脂充填が容易になる。 In order to manufacture the stopper plug of the present invention, injection molding is performed. It is difficult to form many thin portions such as the bridge 423, the spout weakened portion 98, the top plate weakened portion 31, and the concave portion weakened portion 32 at the two hinges of the second hinge 51 and the first hinge 53. As described above, the resin filling is facilitated by forming with a multi-point gate such as the first gate 11 and the second gate 12.
本発明の打栓口栓は、プルリング９３を使用する場合、引っ張り強度も高い必要があり、かつ、天板側脆弱部３１、凹部側脆弱部３２それぞれの脆弱部やブリッジ４２３では一定の引張り強度で破断する多様な特質を持っている必要がある。特に、ヒンジキャップなので、溶融時の流動性（ＭＩＦ）も高い必要がある。そこで、嵌合口栓の材質は、ポリプロピレン、ポリエチレンなどのオレフィン系樹脂で、単一樹脂でもかまわないが、出来る限りそれらの共重合樹脂である事が好ましい。内容物や使用環境にもよるが、エチレン酢酸ビニル樹脂、エチレンアクリル酸共重合樹脂などを添加した混合樹脂でもかまわない。実際に使用する場合は、各種樹脂を用いて成形した後、容器本体に嵌合し、充填予定の内容物を使用して、環境ストレスクラッキング試験を実施し、判断する。 When the pull ring 93 is used, the plug stopper of the present invention needs to have high tensile strength, and has a certain tensile strength at the brittle portion of each of the top plate side weak portion 31 and the concave portion side weak portion 32 and the bridge 423. It is necessary to have various qualities to break at. In particular, since it is a hinge cap, it needs to have high fluidity (MIF) upon melting. Therefore, the material of the fitting plug is an olefin resin such as polypropylene or polyethylene, and it may be a single resin, but is preferably a copolymer resin thereof as much as possible. Depending on the contents and usage environment, a mixed resin to which an ethylene vinyl acetate resin, an ethylene acrylic acid copolymer resin or the like is added may be used. In actual use, after molding using various resins, it is fitted to the container body, and the content to be filled is used to conduct an environmental stress cracking test to make a judgment.
本発明の打栓口栓は、以上の様なもので、キャップを開かなくても、開封の有無が容易に判断できるメリットがあると共に、容器と口栓を分解するのにナイフなどの道具が必要ではなく、分解に大きな力が要らないので、だれでも簡単に分解が出来る口栓である。
また、本発明の打栓口栓は通常の射出成形が可能で量産性も高い。その上、打栓式の口栓なので、キャッピングマシンも回転動作が必要でないので、容器の内容物を充填する機械も安価に作成できるなど、メリットが大きい。
The stopper plug of the present invention is as described above, and there is an advantage that it is possible to easily determine the presence or absence of opening without opening the cap, and a tool such as a knife is used to disassemble the container and the stopper. It is not necessary and does not require great force for disassembly, so it is a plug that anyone can easily disassemble.
Further, the stopper plug of the present invention can be subjected to normal injection molding and has high mass productivity. In addition, since it is a stopper-type plug, the capping machine does not need to be rotated, so there is a great merit that a machine for filling the contents of the container can be made at low cost.
