次に、本発明のヒンジキャップの作用効果について説明する。
本発明は、上蓋Ｃの外周壁３１の係合部３３とキャップ本体Ｂの係合筒部６の蓋係合部１４とを係合させるとともに、上蓋Ｃの密封リング３２とキャップ本体Ｂの注出筒５とを係合させ、上蓋Ｃをキャップ本体Ｂに閉蓋した後、容器Ａ内に内容液を充填し、口筒部１に閉蓋したヒンジキャップを上方から打栓する。 Next, the effect of the hinge cap of this invention is demonstrated.
In the present invention, the engaging portion 33 of the outer peripheral wall 31 of the upper lid C and the lid engaging portion 14 of the engaging cylinder portion 6 of the cap body B are engaged, and the sealing ring 32 of the upper lid C and the cap body B After engaging the outlet cylinder 5 and closing the upper lid C on the cap body B, the container A is filled with the content liquid, and the hinge cap closed on the mouth tube portion 1 is plugged from above.

打栓時には、キャップ本体Ｂの係合筒部６の内筒１２外周と、外筒１３の内周により、容器Ａの口筒部１を挟持するとともに、キャップ本体Ｂの係合突条１９の上部が、容器Ａ口筒部１の係合突部２下端部と係合し、キャップ本体Ｂの抜け落ちを防止して容器Ａの口筒部１に装着される。   At the time of stoppering, the outer tube 13 of the cap body B is sandwiched between the outer periphery of the inner tube 12 of the engagement tube portion 6 of the cap body B and the inner periphery of the outer tube 13, and the engagement protrusion 19 of the cap body B is clamped. The upper portion engages with the lower end portion of the engagement protrusion 2 of the container A mouth tube portion 1 to prevent the cap body B from falling off and is attached to the mouth tube portion 1 of the container A.

本発明のヒンジキャップは、キャップ本体Ｂの係合筒部６の内筒１２外周が容器Ａの口筒部１内周に密着するとともに、キャップ本体Ｂの外筒１３内周の係合面部１８が容器Ａの係合突部２の係合面２ａに密着するので、容器内の内容液が外に漏れることを防ぐことができる。   In the hinge cap of the present invention, the outer periphery of the inner cylinder 12 of the engaging tube portion 6 of the cap body B is in close contact with the inner periphery of the mouth tube portion 1 of the container A, and the engaging surface portion 18 of the inner periphery of the outer tube 13 of the cap body B. Is in close contact with the engagement surface 2a of the engagement protrusion 2 of the container A, so that the content liquid in the container can be prevented from leaking outside.

内容液を全て使用した後、ヒンジキャップを容器から取外して分別廃棄する際には、まず、上蓋Ｃを開蓋した後、上蓋Ｃを把持して下後方に引張る。
上蓋Ｃを下後方に引張ると、ヒンジＤを介して、キャップ本体Ｂの係合筒部６の外壁部２５が引張られ、外壁部２５と連結部２３との縦弱化部２７、および上係合壁部２１との縦弱化部２８を切断していき、まず、縦弱化部２８が切断され、ついで、縦弱化部２７が切断され、図３（ａ）に示すように、外壁部２５が連結壁部１７から離される。 When the hinge cap is removed from the container and discarded after the content liquid has been used, the upper lid C is first opened, and then the upper lid C is gripped and pulled downward.
When the upper lid C is pulled downward and rearward, the outer wall portion 25 of the engaging cylinder portion 6 of the cap body B is pulled through the hinge D, the longitudinal weakening portion 27 between the outer wall portion 25 and the connecting portion 23, and the upper engagement. The longitudinal weakening portion 28 with the wall portion 21 is cut, first the longitudinal weakening portion 28 is cut, then the longitudinal weakening portion 27 is cut, and the outer wall portion 25 is connected as shown in FIG. Separated from the wall 17.

次に、上蓋Ｃを横方向に引張ると、外壁部２５ともに下係合壁部２２の側端１６ｂ側が引張られ、下係合壁部２２と内壁部２４との縦弱化部２６を切断するとともに、上係合壁部２１との横弱化部２０を徐々に切断し、図３（ｂ）に示すように、外筒１３から下係合壁部２２を引き離していく。   Next, when the upper lid C is pulled in the lateral direction, the side end 16b side of the lower engagement wall portion 22 is pulled together with the outer wall portion 25, and the longitudinal weakening portion 26 between the lower engagement wall portion 22 and the inner wall portion 24 is cut. Then, the lateral weakening portion 20 with the upper engagement wall portion 21 is gradually cut, and the lower engagement wall portion 22 is pulled away from the outer cylinder 13 as shown in FIG.

下係合壁部２２が、外筒１３から引き離されていくと、下係合壁部２２内周下端の係合突条１９と容器Ａの係合突部２との係合が外れるとともに、下係合壁部２２が連結壁部１７を介して、残部の外筒１３に連結された状態となり、さらに下係合壁部２２を上方に引張ると、キャップ本体Ｂが簡単に容器Ａの口筒部１から外れて分別廃棄することができる。   When the lower engagement wall portion 22 is pulled away from the outer cylinder 13, the engagement protrusion 19 at the lower end of the inner periphery of the lower engagement wall portion 22 and the engagement protrusion 2 of the container A are disengaged, When the lower engaging wall portion 22 is connected to the remaining outer cylinder 13 via the connecting wall portion 17, and the lower engaging wall portion 22 is further pulled upward, the cap body B can be easily opened to the mouth of the container A. It can be separated from the cylindrical portion 1 and discarded.

本実施例のキャップでは、キャップ本体Ｂの外筒１３の横弱化部２０および縦弱化部２６、２７、２８は、打栓時に破損することはなく、容器内の密封を保つことができる。   In the cap of the present embodiment, the lateral weakening portion 20 and the longitudinal weakening portions 26, 27, and 28 of the outer cylinder 13 of the cap main body B are not damaged at the time of stoppering, and the inside of the container can be maintained.

さらに、キャップ本体Ｂを分別廃棄するため、図４に示すように、外筒１３から下係合壁部２２を引き離した際に、容器Ａの係合面２ａと外筒１３の係合面部１８の下部との係合が外れ、その分、係合面２ａとキャップ本体Ｂの係合面部１８との係合面が小さくなり、より簡単に、キャップ本体Ｂを容器Ａから外すことができる。   Further, in order to separate and discard the cap body B, as shown in FIG. 4, when the lower engagement wall portion 22 is pulled away from the outer cylinder 13, the engagement surface 2 a of the container A and the engagement surface portion 18 of the outer cylinder 13 are separated. And the engagement surface between the engagement surface 2a and the engagement surface portion 18 of the cap body B becomes smaller, and the cap body B can be removed from the container A more easily.

上記実施形態では、キャップ本体Ｂの連結壁部１７の内壁部２４と外壁部２５との間に間隔ａを開けて形成しただけであるが、別実施例として、図５に示すように、内壁部２４外周と外壁部２５内周の間を、下端部に配設された破断可能な薄肉部３５、および、薄肉部３５の所定の位置から上方に延びる破断可能な突部３６を介して連設するようにしてもよい。   In the above embodiment, the gap a is only formed between the inner wall portion 24 and the outer wall portion 25 of the connecting wall portion 17 of the cap body B. As another example, as shown in FIG. The outer periphery of the portion 24 and the inner periphery of the outer wall portion 25 are connected via a breakable thin portion 35 disposed at the lower end portion and a breakable protrusion 36 extending upward from a predetermined position of the thin portion 35. You may make it install.

薄肉部３５、および突部３６を設けたことによって、ヒンジキャップを成形する際に、成形樹脂の流れを良くすることができ、成形時の不良を改善することができる。   By providing the thin portion 35 and the protrusion 36, the flow of the molding resin can be improved when the hinge cap is molded, and defects during molding can be improved.

また、内壁部２４が薄肉部３５および突部３６を介して外壁部２５が連設されているので、打栓時に、内壁部２４とともに外壁部２５の剛性も加えられ、内壁部２４が変形することを防止でき、容器内の密封を保つことができる。   Further, since the outer wall portion 25 is connected to the inner wall portion 24 through the thin portion 35 and the protrusion 36, the rigidity of the outer wall portion 25 is added together with the inner wall portion 24 at the time of stoppering, and the inner wall portion 24 is deformed. This can be prevented, and the inside of the container can be kept sealed.

本発明は、ヒンジキャップにおいて、打栓後の容器内の密封を保つことができるとともに、上蓋を引張ることによって、簡単にヒンジキャップを容器口部から取外して、分別廃棄することができるので、各種の内容液の容器の分別廃棄可能のヒンジキャップとして、広く利用することができる。   In the present invention, the hinge cap can keep the inside of the container sealed after being plugged, and by pulling the upper lid, the hinge cap can be easily removed from the container mouth and disposed of separately. It can be widely used as a hinge cap capable of separating and discarding the container of the content liquid.
