Description

本発明は、ヒンジキャップ、とくに容器内に充填した加熱殺菌された内容液によりキャップの上蓋内の空気が加熱され、内圧が上昇することにより、上蓋が開蓋することを防止したヒンジキャップに関するものである。   The present invention relates to a hinge cap, in particular, a hinge cap that prevents the upper lid from being opened by heating the air in the upper lid of the cap by the heat-sterilized content liquid filled in the container and increasing the internal pressure. It is.

殺菌のため加熱された内容液を充填するヒンジキャップにおいて、内容液を充填し、ヒンジキャップを打栓した後、容器内部を殺菌し、次いで容器外部より温水シャワーで洗浄、冷却することは従来より行われている。
そしてまた、殺菌のための加熱処理によるキャップ内の空気圧の上昇により、上蓋が開蓋することを防止するために、キャップ本体の係合用の突出部に係合する上蓋の突出部に、主突起と補助突起を設け、係止機構を二重にして上蓋の開蓋を防止することも、従来より知られている（例えば、特許文献１参照）。
特開平１１−３５０６１号公報 In hinge caps filled with heated content liquid for sterilization, filling the content liquid and capping the hinge cap, then sterilizing the inside of the container, then washing and cooling with a hot water shower from the outside of the container has been conventional Has been done.
Further, in order to prevent the upper lid from opening due to an increase in air pressure in the cap due to the heat treatment for sterilization, the main protrusion is formed on the protrusion of the upper lid that engages with the protrusion for engagement of the cap body. It is also conventionally known to provide an auxiliary protrusion and to double the locking mechanism to prevent the upper lid from being opened (see, for example, Patent Document 1).
JP-A-11-35061

しかしながら、上記特許文献１記載の従来のヒンジキャップは、補助突起の係合によって、それ以上の上蓋の上昇を抑制し、上蓋の開蓋を防止するようにしているので、使用者が上蓋を開閉するためには、補助突起をキャップ本体の係合用の突出部を乗り越えさせなければならず、開蓋の際に大きな力が必要であるという問題があった。   However, since the conventional hinge cap described in Patent Document 1 prevents the upper lid from further rising and prevents the upper lid from being opened by engaging the auxiliary protrusion, the user opens and closes the upper lid. In order to do this, the auxiliary protrusion has to get over the protrusion for engagement of the cap body, and there is a problem that a large force is required for opening the lid.

本発明は、上記問題を解決することを課題とし、加熱によるキャップ内の空気の圧力上昇により、ヒンジキャップの上蓋が圧力上昇により開蓋することがなく、また、使用者がそれ程強い力を必要としないで上蓋を開閉できるヒンジキャップを提供することを目的とする。   An object of the present invention is to solve the above-mentioned problems, and the upper lid of the hinge cap does not open due to the increase in pressure due to the increase in the pressure of air in the cap due to heating, and the user needs a strong force. An object of the present invention is to provide a hinge cap that can open and close the upper lid without the need to do so.

本発明は、上記の課題を解決するため、ヒンジキャップとして、容器の口筒部に取着され、キャップ本体と上蓋からなるヒンジキャップにおいて、キャップ本体は、注出筒と、容器口筒部に嵌着される係合筒部と、係合筒部の外周に設けられ、上端外周にヒンジを連設する外周筒部とを具え、係合筒部は、上端に上蓋と嵌合する蓋係合部を具え、外周筒部は、ヒンジの反対側の外周上端に、切断可能な弱化部を介して側方に張り出した蓋保持部が設けられ、蓋保持部は、該弱化部に連接された底壁と、底壁の両側に立設された側壁と、双方の側壁の前縁上部の間に架設された押さえ部材を具え、側壁の内面後部には、係合凸部を設け、押さえ部の後面には、係合面を設け、上蓋は、頂壁と、外筒壁を具え、外筒壁の内周下端は、拡径され、キャップ本体の係合筒部の蓋係合部と嵌合する係合部が設けられ、外周下端の所定の位置には、ヒンジが連設され、ヒンジの反対側には、中央に突出部を設けた摘み部が配設され、摘み部の突出部には、根本部両側に、蓋保持部の側壁の係合凸部と嵌合する係合凹部が形成され、中央部に、蓋保持部の押さえ部材と当接する傾斜面が形成され、該摘み部の突出部が、キャップ本体の蓋保持部の押さえ部材に嵌合されていることを特徴とする構成を採用する。

次に、本実施例のヒンジキャップの作用効果について説明する。
ヒンジキャップの閉蓋にあたっては、上蓋Ｂの係合部３３とキャップ本体Ａの蓋係合部１２とを嵌合させるとともに、上蓋Ｂの摘み部３４の突出部３４ａとキャップ本体Ａの蓋保持部１９の押さえ部材２２とを嵌合させ、上蓋Ｂをキャップ本体Ａに閉蓋する。
容器本体内に加熱された内容液を充填し、容器本体の口筒部に、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 a present Example is demonstrated.
When closing the hinge cap, the engaging portion 33 of the upper lid B and the lid engaging portion 12 of the cap body A are fitted together, and the protruding portion 34a of the knob 34 of the upper lid B and the lid holding portion of the cap body A The 19 pressing members 22 are fitted, and the upper lid B is closed to the cap body A.
The container body is filled with the heated content liquid, and a closed hinge cap is plugged into the mouth tube portion of the container body from above.

本発明のヒンジキャップは、上蓋Ｂの摘み部３４の傾斜面３６と係合凹部３７が、キャップ本体Ａの蓋保持部１９の係合面２４と係合凸部２３に嵌合し、押さえ部材２２が摘み部３４の傾斜面３６に当接することにより、上蓋Ｂのキャップ本体Ａに対する嵌合力を付加するので、上蓋Ｂの係合部３３とキャップ本体Ａの蓋係合部１２との嵌合力がそれほど強くなくても、上蓋Ｂ内の内圧上昇による開蓋を防止することができる。
加熱充填直後のキャップ本体Ａと上蓋Ｂの嵌合力は、６〜１３ニュートンであればよく、蓋係合部１２による嵌合力と蓋保持部１９による嵌合力への配分は、適宜に設定することができる。
In the hinge cap of the present invention, the inclined surface 36 of the knob 34 of the upper lid B and the engaging recess 37 are fitted into the engaging surface 24 and the engaging convex 23 of the lid holding portion 19 of the cap body A, and the holding member 22 abuts against the inclined surface 36 of the knob 34 to add a fitting force of the upper lid B to the cap body A, and therefore, a fitting force between the engaging portion 33 of the upper lid B and the lid engaging portion 12 of the cap body A. Is not so strong, it is possible to prevent the lid from being opened due to an increase in internal pressure in the upper lid B.
The fitting force between the cap body A and the upper lid B immediately after heating and filling may be 6 to 13 Newton, and the distribution between the fitting force by the lid engaging portion 12 and the fitting force by the lid holding portion 19 should be set appropriately. Can do.

上蓋Ｂを開蓋する際には、キャップ本体Ａの蓋保持部１９に指などを掛け、上方に持ち上げると、図３に示すように、キャップ本体Ａの蓋保持部１９と外周筒部５とを連設する弱化部１８が切断され、蓋保持部１９が上蓋Ｂの摘み部３４に嵌合したまま、上蓋Ｂが開蓋される。
必要であれば、開蓋後に蓋保持部１９の押さえ部材２２の下方から力を加え、押さえ部材２２を変形させ、摘み部３４と蓋保持部１９との嵌合を外し、蓋保持部１９から摘み部３４を外してもよい。 When opening the upper lid B, when a finger or the like is put on the lid holding portion 19 of the cap main body A and lifted upward, as shown in FIG. The weakened portion 18 is continuously cut, and the upper lid B is opened while the lid holding portion 19 is fitted to the knob 34 of the upper lid B.
If necessary, a force is applied from below the pressing member 22 of the lid holding part 19 after the lid is opened, the pressing member 22 is deformed, the fitting between the knob 34 and the lid holding part 19 is removed, and the lid holding part 19 is removed. The knob 34 may be removed.

本発明のヒンジキャップは、打栓時の閉蓋により、上蓋Ｂの摘み部３４の突出部３４ａとキャップ本体Ａの蓋保持部１９の押さえ部材２２が嵌合し、上蓋Ｂのキャップ本体Ａに対しての嵌合力を付加するので、上蓋Ｂの係合部３３とキャップ本体Ａの蓋係合部１２との嵌合力を弱く設定することができ、使用者による開蓋の際には、蓋保持部１９と摘み部３４による上蓋Ｂとキャップ本体Ａとの嵌合を外すことができ、使用者がより上蓋を開蓋し易くすることができる。 The hinge cap of the present invention, the closed during capping, the pressing member 22 of the cover holding portion 19 of the protruding portion 34a and the cap body A of the knob portion 34 of the upper lid B is fitted, the cap body A of the top cover B Therefore, the fitting force between the engaging portion 33 of the upper lid B and the lid engaging portion 12 of the cap body A can be set weakly. When the user opens the lid, The upper lid B and the cap main body A can be disconnected from the lid holding portion 19 and the knob portion 34, and the user can more easily open the upper lid.

本発明のヒンジキャップは、容器を廃棄する際、まず、上蓋Ｂを開蓋し、上蓋Ｂを引張り上げることにより、ヒンジＣを介してキャップ本体Ａの外周筒部５を上昇させ、外周筒部５と係合筒部４との間の弱化片１５を切断する。
次に、外周筒部５と係合筒部４との間の連結片１４を支点として、外周筒部５のヒンジＣ側が上昇し、さらに上蓋Ｂを引張ることで、外周筒部５の連結片１４側も上昇させる。 When discarding the container, the hinge cap of the present invention first opens the upper lid B and pulls the upper lid B up to raise the outer peripheral cylindrical portion 5 of the cap main body A via the hinge C, and the outer peripheral cylindrical portion. The weakening piece 15 between 5 and the engagement cylinder part 4 is cut | disconnected.
Next, with the connecting piece 14 between the outer peripheral cylindrical part 5 and the engaging cylindrical part 4 as a fulcrum, the hinge C side of the outer peripheral cylindrical part 5 rises and the upper lid B is pulled, whereby the connecting piece of the outer peripheral cylindrical part 5 Also raise the 14th side.

最後に、連結片１４を介して係合筒部４の外筒１１の連結片１４側が引張られることで、係合筒部４の外筒１１が変形し、キャップ本体Ａと容器本体の口筒部との係合を外して、簡単にヒンジキャップを容器本体から外して、分別廃棄することができる。   Finally, when the connection piece 14 side of the outer cylinder 11 of the engagement cylinder part 4 is pulled through the connection piece 14, the outer cylinder 11 of the engagement cylinder part 4 is deformed, and the cap body A and the mouthpiece of the container body The hinge cap can be easily removed from the container main body by disengaging from the part, and can be separated and discarded.

本発明は、ヒンジキャップにおいて、容器内の内容液、または、温水シャワーによりヒンジキャップ内の空気が加熱され、内圧が上昇しても、ヒンジキャップの上蓋が開蓋することを防止でき、各種の加熱充填する内容液の容器のヒンジキャップとして広く利用することができる。   The present invention can prevent the upper lid of the hinge cap from opening even if the contents in the container or the air in the hinge cap is heated by the hot water shower in the hinge cap and the internal pressure rises. It can be widely used as a hinge cap for a container of contents liquid to be heated and filled.
