Abstract
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、高速で製造性は高いが、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、容器と口栓の隙間を埋め、密封性を確保していた。又、ポリエチ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 is high speed and highly manufacturable. However, when it is manufactured, the mouth portion may be thick, and the dimensional accuracy of the mouth portion is very low. For this reason, the plugs to be fitted are made of a flexible resin, and are pressed into the plugs and fitted to fill the gap between the container and the plugs to ensure the sealing performance. In addition, a crystalline resin such as polyethylene can be easily made into a thin-walled hinge that can be aligned in 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。
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容易ではなく、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.
For this reason, it is necessary to use tools such as cutters to separate them according to their materials. For children and the elderly, it is not easy to separate them according to the materials used, and they will be 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押圧片の先端上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押圧片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 top surface of the tip of the pressing piece on the side opposite to the hinge of the lid body that is coupled to the cap body with a hinge, and pressed on the upper edge of the arc-shaped outer peripheral surface of the cap body via a thin portion. Engagement protrusions are provided on the arcuate engagement pieces that are arranged so as to face each other from the outside at the tip of the piece, 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.

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.

以下、本発明の打栓口栓１の実施の形態例について、図を用いて詳細に説明する。
実施形態例に使用される容器本体２は、図１に示すように、通常のボトルで、射出パリソンを延伸ブロー成形したボトルや、通常のブローボトル、紙や金属箔やプラスチックなどを積層した紙容器に融着した口部を持つものであってもかまわない。これらの容器で、打栓して口栓を嵌合可能にした容器である。座屈強度が低い容器の場合は、口部近傍に打栓圧力を受ける為の鍔２１が設けられている事が好ましい。
打栓口栓１は、図２に示すように、口栓本体３とキャップ４がヒンジ５により繋がって、開閉可能になっている。
Hereinafter, embodiments of the stopper plug 1 of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the container body 2 used in the embodiment is a normal bottle, a bottle in which an injection parison is stretch-blow-molded, a normal blow bottle, a paper in which paper, metal foil, plastic, or the like is laminated. It may have a mouth fused to the container. These containers are containers that can be plugged and fitted with plugs. In the case of a container with low buckling strength, it is preferable that a flange 21 for receiving a stoppering pressure is provided in the vicinity of the mouth.
As shown in FIG. 2, the stopper plug 1 is openable and closable by connecting the stopper body 3 and the cap 4 with a hinge 5.
打栓口栓１は、成形された状態では、図３、図５に示すように、口栓本体３には、注出口６を有する天板部７と天板部周縁から垂下している筒状側壁８とが設けられている。
また、キャップは、注出口を覆う周状突起９と、キャップ周縁と切断可能な接合部１０によって繋げられた嵌合片１１を設けられている。
口栓本体３のヒンジ５反対側の筒状側壁には嵌合片１１を挿入する嵌合孔１２を設けられ、嵌合孔の外観側には嵌合壁１３があり、その嵌合壁に連接する開口部１４には、嵌合片１１先端の嵌合爪１１２が入り込める隙間が設けられている。
これらの図では、口栓本体の天板７には、脆弱部１５を周囲に設けた注出口閉鎖部１６とプルリング１７と筒状突起１８で構成される注出口６が設けられ、内部にはインナーリング１９が設けられているが、注出口６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、周状突起９があるが、口栓本体側の形状に合わせたものであれば、コンタクトリング等、他の方式でもかまわない。
As shown in FIGS. 3 and 5, the stopper plug 1 is formed into a top plate portion 7 having a spout 6 and a tube hanging from the periphery of the top plate portion, as shown in FIGS. 3 and 5. A side wall 8 is provided.
Moreover, the cap is provided with the fitting piece 11 connected by the circumferential protrusion 9 which covers the spout, and the joint part 10 which can be cut | disconnected from a cap periphery.
A fitting hole 12 for inserting the fitting piece 11 is provided on the cylindrical side wall on the opposite side of the hinge 5 of the plug body 3, and a fitting wall 13 is provided on the appearance side of the fitting hole. The connecting opening 14 is provided with a gap into which the fitting claw 112 at the tip of the fitting piece 11 can enter.
In these figures, the top plate 7 of the plug body is provided with a spout 6 composed of a spout closing portion 16, a pull ring 17 and a cylindrical projection 18 provided with a fragile portion 15 around the inside. Although the inner ring 19 is provided, the structure based on the inside of the spout 6 and its prevention of liquid leakage may be different.
There are also circumferential projections 9 on the cap side, but other types such as a contact ring may be used as long as it matches the shape of the plug body.
図４、図６は、キャップ４を初めて閉めた状態の口栓で、嵌合片１１は嵌合孔１２の中に入って嵌合し、嵌合片１１の表面１１１は嵌合壁１３に覆われている。したがって、嵌合壁に連接する開口部１４からは、嵌合片１１の嵌合爪１１２だけが見えている。したがって、嵌合壁１３のキャップ側から開口部１４側までの高さは、嵌合片表面１１１と結合部１０の合計長さに近い長さが必要になる。
通常、内容物が充填された容器本体２の口元に、この図４の状態で本発明の口栓１が容器の口元に乗せられ、上から圧力を掛け、打栓される。ネジ方式のキャップでは、回転しながらそのネジピッチに合わせて押し込みながらキャッピングする必要が出てくる。
FIGS. 4 and 6 are caps in a state in which the cap 4 is closed for the first time. The fitting piece 11 enters and fits into the fitting hole 12, and the surface 111 of the fitting piece 11 faces the fitting wall 13. Covered. Therefore, only the fitting claw 112 of the fitting piece 11 is visible from the opening 14 connected to the fitting wall. Accordingly, the height of the fitting wall 13 from the cap side to the opening 14 side needs to be close to the total length of the fitting piece surface 111 and the coupling portion 10.
Normally, the mouth plug 1 of the present invention is placed on the mouth of the container in the state shown in FIG. 4 at the mouth of the container body 2 filled with the contents, and the stopper is applied with pressure from above. In the screw type cap, it is necessary to perform capping while pushing in accordance with the screw pitch while rotating.
図９はキャップを開口し始めた時の断面図で、嵌合片１１の嵌合爪１１２が、嵌合壁１３の開口部１４側端面に嵌合して、嵌合片１１の嵌合孔１２からの抜けを防止している。この為、キャップの開口する力は、嵌合片１１とキャップ周縁と嵌合片とをつないでいる結合部１０に集中して掛かる事になり、この矢印の部分で結合部１０が切れてしまう。この結合部１０は、通常、キャップ周縁側で切れる事が好ましいので、嵌合部嵌合片側では、根元に肉を付けて丸める事や、太くするなどの対策を採り、反対にキャップ周縁側では、根元の角を立て、細めにしておくなどの対策を採っておく。 FIG. 9 is a cross-sectional view when the cap starts to be opened. The fitting claw 112 of the fitting piece 11 is fitted to the end face of the fitting wall 13 on the opening 14 side, and the fitting hole of the fitting piece 11 is shown. 12 is prevented from coming off. For this reason, the opening force of the cap is concentrated on the connecting portion 10 that connects the fitting piece 11, the periphery of the cap, and the fitting piece, and the connecting portion 10 is cut at the portion indicated by the arrow. . Usually, it is preferable that the coupling portion 10 is cut at the cap peripheral side. Therefore, on the fitting portion fitting piece side, a measure such as adding a flesh to the base and rounding or thickening is taken, and conversely on the cap peripheral side. Measures such as raising the corner of the root and making it thinner.
図７、図１０は、一度閉めたキャップを開けた後の状態を示している。嵌合片１１は、嵌合孔１２の中に落下して、開口部隙間１４１に入り込み、嵌合壁に覆われていた嵌合片の表面１１１が開口部１４から見えるようになる。この為、一度でも開封したかどうかは、単に容器のキャップを開かなくても開口部１４の嵌合片表面が見えるようになっているかで、判断できる。
この嵌合片の表面１１１には、彫刻で「開封」、「済」「開」といった文字や記号を入れたり、その表面１１１部分だけ、キャップの色と違う色に印刷や色入れ等で着色したりして、開封した事を明確に分りやすく表示する事ができる。
この為、隙間１４１は嵌合片１１に対し、大きめに設計してクリアランスを充分に取っておく事が好ましい。
7 and 10 show a state after the cap once closed is opened. The fitting piece 11 falls into the fitting hole 12 and enters the opening gap 141 so that the surface 111 of the fitting piece covered with the fitting wall can be seen from the opening portion 14. For this reason, whether or not it has been opened once can be determined by whether or not the surface of the fitting piece of the opening 14 can be seen without simply opening the cap of the container.
The surface 111 of this fitting piece is engraved with letters and symbols such as “opened”, “finished” and “opened”, or only the surface 111 portion is colored by printing or color-filling in a color different from the cap color. It is possible to display clearly that it has been opened.
For this reason, it is preferable that the gap 141 is designed to be large with respect to the fitting piece 11 so that a sufficient clearance is provided.
内容物を使い終わり、容器や口栓を廃棄する時は、口栓１と容器本体２とは材料が異なる場合が多いので、口栓と容器本体とを分離し、各々の材料別に分別して廃棄するようにする。図１１は、本発明の打栓口栓の脆弱部を示している。すなわち、口栓本体の天板６と筒状側壁８との境の天板側脆弱部３１と、筒状側壁８における嵌合孔左右の嵌合孔側脆弱部３２を設けている。天板側脆弱部３１は、口栓本体の天板６と筒状側壁８との境の内、嵌合壁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、嵌合しているアンダーカット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。 When you are done using the contents and discard the container or spigot, the material of the spigot 1 and the container main body 2 is often different, so separate the spigot from the container main body and dispose of it separately for each material. To do. FIG. 11 shows a fragile part of the stopper plug of the present invention. That is, a top plate side weakened portion 31 at the boundary between the top plate 6 and the cylindrical side wall 8 of the plug main body and a fitting hole side weakened portion 32 on the left and right of the fitting hole in the cylindrical side wall 8 are provided. The top plate-side weakened portion 31 makes more than half of the boundary between the top plate 6 and the cylindrical side wall 8 of the plug body including the vicinity of the fitting wall a weakened portion. If the fragile part is more than half, the entire plug is deformed and displaced so that the rest of the undercut portion fitted is slipped through, and the plug can be pulled out with almost no resistance.
口栓と容器本体を分解は、図１２、図１３、図１４の順で行われる。
まず、図１２、図１５で示すように、嵌合孔１２を利用して、嵌合壁１３を外側に引き出す事で、図２３に図示した、左右ある嵌合孔側脆弱部３２の表面側の嵌合壁側脆弱部３２ａを切断する。
次に、図１３、図１６で、嵌合壁１３を掴んでさらに上側に曲げて、図２３に図示した、内側の側壁側脆弱部３２ｂを切断する。
さらに、図１４、図１７で、嵌合壁近傍の天板側脆弱部３１を切断し、壁や側壁で構成される嵌合孔１２部分全体が、口栓本体３から外れる。
ここまで破壊・切断すると、後は天板側脆弱部３１の一部だけで、しかも、半分以上が天板側脆弱部３１なので、ほとんど引っ張り力を使わないで、天板側脆弱部３１の残り部分が開いたり、全体が歪んで、容器本体２の口元から、口栓１が抜けて分離する事ができる。
The mouth plug and the container body are disassembled in the order of FIG. 12, FIG. 13, and FIG.
First, as shown in FIGS. 12 and 15, by using the fitting hole 12 and pulling out the fitting wall 13 to the outside, the surface side of the left and right fitting hole side weak part 32 shown in FIG. 23 is shown. The fitting wall side weak part 32a is cut | disconnected.
Next, in FIG. 13 and FIG. 16, the fitting wall 13 is grasped and further bent upward, and the inner side wall weak portion 32 b shown in FIG. 23 is cut.
Further, in FIG. 14 and FIG. 17, the top plate-side weakened portion 31 near the fitting wall is cut, and the entire fitting hole 12 portion constituted by the wall and the side wall is detached from the plug body 3.
After breaking and cutting so far, only a part of the top plate-side weakened portion 31 is used, and more than half of the top-plate-side weakened portion 31 is used. A part is opened or the whole is distorted, and the plug 1 can be detached from the mouth of the container body 2 and separated.
なお、本発明のもうひとつの実施形態は、図１８で示すように、嵌合孔１２近傍だけは天板側脆弱部を設けず、その嵌合壁１３を掴んで、それを引き上げて打栓口栓１を容器本体２から分離する方法である。この方法では、図１９、図２０、図２１、図２２で示すように、ヒンジ部分のような薄肉部分を分解のような力の掛かる時でも使用しないで、嵌合孔１２周囲の嵌合壁１３を掴んで、そのまま一度外側に押し出し（図２０）、それを外側に引っ張って（図２１）、さらに嵌合壁１３を掴んでヒンジを中心に上に引き上げる（図１９、図２２）ようにして、打栓口元１を容器本体２から外す事ができる。 In another embodiment of the present invention, as shown in FIG. 18, the top plate side weakened portion is not provided only in the vicinity of the fitting hole 12, and the fitting wall 13 is grasped and pulled up to be plugged. In this method, the spigot 1 is separated from the container body 2. In this method, as shown in FIGS. 19, 20, 21, and 22, the thin wall portion such as the hinge portion is not used even when a force such as disassembly is applied, and the fitting wall around the fitting hole 12 is used. 13 is pushed out as it is (FIG. 20), pulled outward (FIG. 21), and further, the fitting wall 13 is grasped and pulled upward with the hinge as a center (FIGS. 19 and 22). Thus, the stopper 1 can be removed from the container body 2.
嵌合孔１２左右筒状側壁に設けた脆弱部１５は、図２３で示す断面図ように、左右それぞれの嵌合孔を構成する表側の嵌合壁１３と筒状側壁８とが分離可能な嵌合壁側の脆弱部１５ａと、筒状側壁側の脆弱部１５ｂとで構成されている。分離する時には、この嵌合壁側の脆弱部１５ａを先に破壊して嵌合壁１３を前に倒し（図１５、図２０）、その後、嵌合壁１３を掴んで筒状側壁側の脆弱部１５ｂを破壊して筒状側壁の一部を引き上げる（図１６、図２１）ようにする。このように嵌合孔１２の左右それぞれの２箇所が脆弱部で構成する事で、容易に段階的に分離が可能であり、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。 As shown in the sectional view of FIG. 23, the weakened portion 15 provided on the left and right cylindrical side walls of the fitting hole 12 is separable from the front side fitting wall 13 and the cylindrical side wall 8 that constitute the left and right fitting holes. It is comprised by the weak part 15a by the side of a fitting wall, and the weak part 15b by the side wall side of a cylinder. When separating, the fragile portion 15a on the fitting wall side is first destroyed and the fitting wall 13 is brought down (FIGS. 15 and 20), and then the fitting wall 13 is grasped to fragile the cylindrical side wall side. The part 15b is destroyed and a part of the cylindrical side wall is pulled up (FIGS. 16 and 21). As described above, each of the two left and right portions of the fitting hole 12 is constituted by a weak portion, so that it can be easily separated in stages, and the compression force when the stopper is plugged into the mouth of the container. Therefore, it can be fitted without breaking.
本発明の打栓口栓は、プルリング１７を使用する場合、引っ張り強度も高い必要があり、かつ、それぞれの脆弱部１５、３１、３２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 17 is used, the plug stopper of the present invention needs to have high tensile strength, and each of the fragile portions 15, 31 and 32 has various characteristics that break at a constant tensile strength. There is a need. 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、容器と口栓とを分離するのにナイフなどの道具が必要ではなく、分離に大きな力が要らないので、だれでも簡単に分離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 has an advantage that it can be easily determined whether or not the container is opened without opening the cap, and a tool such as a knife is used to separate the container and the stopper. This is a plug that can be easily separated by anyone because it does not require a large force for separation. 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.
