Description

【０００１】
【発明の属する技術分野】
本発明は，例えば錠剤カプセル等の粒状物を収納する容器の開口部に取付けられるヒンジキャップに関する。
【０００２】
【従来の技術】
錠剤あるいはカプセル等を収納する容器として，ガラス製あるいはプラスチック製の容器の開口部に，スクリューキャップを開閉自在に取り付けたものが知られている。そのようなスクリューキャップについて，本出願人は先に例えば特開平１１−１８９２８０号を開示している。
【０００３】
また最近では，開閉操作を片手でも容易にできるように，容器の開口部に取付けられるキャップ本体にヒンジを介して蓋体を開閉自在に取付けたヒンジキャップが採用されている。そのようなヒンジキャップについては，例えば実開平６−１２３８１号が公知である。

【発明が解決しようとする課題】
しかしながら，スクリューキャップは両手で開閉しなければならない。このため，開閉操作が面倒である。
【０００６】
一方，ヒンジキャップは開閉操作は容易であるが気密性が劣るといった問題がある。特に糖衣錠などは，水分により表面が白斑しやすく，十分な気密性が必要であるが，そのような場合，従来のヒンジキャップは適さない。
【０００７】
また，ヒンジキャップの場合，錠剤などの取出し口が小さいので，過剰な錠剤が出てしまった場合，容器内に錠剤を速やかに戻しにくい。このため，手のひらに錠剤を出した場合，過剰な錠剤を容器内に戻すのに時間がかかり，その間に手のひらから出た水分で表面が白斑する心配がある。
【０００８】
本発明の目的は，開閉操作が容易なヒンジキャップにおいて，気密性を向上させ，また，錠剤を容器内に戻しやすくすることにある。
【０００９】
【課題を解決するための手段】
本発明によれば，粒状物を収納する容器の開口部に取付けられるヒンジキャップであって，前記容器の開口部に取付けられるキャップ本体と，前記キャップ本体にヒンジを介して開閉自在に取付けられた蓋体を有し，前記キャップ本体は，前記容器の開口部の外周面を囲んで配置されるキャップ周壁部と，前記容器の開口部の上面を塞ぐキャップ天板部を有し，前記キャップ周壁部の内周面には，前記容器の開口部の外周面に形成されたねじ部と螺合するねじ部が形成され，前記キャップ天板部には，前記容器に収納された粒状物を通過させる孔が形成され，前記キャップ天板部の下面には，前記キャップ本体を前記容器の開口部に取り付けた際に，前記容器の開口部の上面及び／又は内周面に押圧接触する環状のシール手段が一体的に形成され，前記蓋体は，閉じた際に前記キャップ天板部の上方に平行に配置される蓋体天板部と，前記蓋体天板部の周囲下方に配置される蓋体周壁部を有し，前記蓋体天板部の下面には，閉じた際に前記孔に挿入される蓋体支柱部が一体的に形成され，前記蓋体支柱部の外周面は，閉じた際に前記孔の内周面に押圧接触し，前記キャップ天板部の下面には，前記キャップ天板部の下面よりも下方に突出し，かつ，前記孔を跨いで配置されたＵの字形状の邪魔棒が取り付けてあり，前記邪魔棒の底部上面には，上向きに突出する突起が設けてあることを特徴とする，ヒンジキャップが提供される。
【００１０】
この場合，例えば，前記キャップ天板部の下面には，前記キャップ本体を前記容器の開口部に取り付けた際に，前記容器の開口部の上面に押圧接触する環状の肉厚部が一体的に形成されている。また例えば，前記キャップ天板部の下面には，前記キャップ本体を前記容器の開口部に取り付けた際に，前記容器の開口部に挿入される筒状のキャップ本体支柱部が一体的に形成され，前記キャップ本体支柱部の外周面には，前記キャップ本体を前記容器の開口部に取り付けた際に，前記容器の開口部の内周面に押圧接触する肉厚部の突起が一体的に形成されている。また例えば，前記蓋体天板部の下面において，前記蓋体支柱部の外側に配置されたストッパーが形成されている。また例えば，前記蓋体支柱部の外周面には，閉じた際に前記孔の内周面に押圧接触する環状のシール手段が一体的に形成されている。
【００１１】
また本発明によれば，粒状物を収納する容器の開口部に取付けられるヒンジキャップであって，前記容器の開口部に取付けられるキャップ本体と，前記キャップ本体にヒンジを介して開閉自在に取付けられた蓋体を有し，前記キャップ本体は，前記容器の開口部の上面を塞ぐキャップ天板部を有し，前記キャップ天板部には，前記容器に収納された粒状物を通過させる孔が形成され，前記キャップ天板部の上面において前記孔の周りには，前記孔に向って低くなる漏斗部が形成され，かつ，前記キャップ天板部の上面には，前記漏斗部の外側を囲む環状壁が形成され，前記キャップ天板部の下面には，前記キャップ天板部の下面よりも下方に突出し，かつ，前記孔を跨いで配置されたＵの字形状の邪魔棒が取り付けてあり，前記邪魔棒の底部上面には，上向きに突出する突起が設けてあることを特徴とする，ヒンジキャップが提供される。
【００１２】
例えば，前記キャップ天板部の下面には，前記孔から離れて配置されたガイド突起が，前記孔の一部もしくは全部を囲んで形成されている。また例えば，前記キャップ天板部の下面において前記孔の近傍には，前記キャップ天板部から下方に突出する突起が形成されている。
【００１３】
【発明の実施の形態】
以下，本発明の好ましい実施の形態にかかるヒンジキャップ１を図面を参照にして説明する。
図１は，本発明の実施の形態にかかるヒンジキャップ１の開いた状態を示す平面図である。
図２は，本発明の実施の形態にかかるヒンジキャップ１を開いた状態を示す底面図である。
図３は，図１におけるＸ−Ｘ断面矢視図である。
図４は，右半分が図１におけるＹ−Ｙ断面矢視図であり，左半分が同じ方向から見たキャップ本体２の側面図である。
図５は，容器５の開口部６に取付けられた本発明の実施の形態にかかるヒンジキャップ１の部分縦断面拡大図である。
【００１４】
これら図１〜５に示すように，本発明の実施の形態にかかるヒンジキャップ１は，キャップ本体２と蓋体３を備えている。これらキャップ本体２と蓋体３は，ヒンジ４を介して接続されており，このヒンジ４を中心に蓋体３を回動させることにより，蓋体３によってキャップ本体２を開閉させるようになっている。キャップ本体２を容器５の開口部６に取付けることにより，ヒンジキャップ１が容器５の開口部６に取付けられるようになっている。なお，図示はしないが，容器５には例えば錠剤，カプセル等の粒状物が収納される。
【００１５】
キャップ本体２は，ヒンジキャップ１を容器５の開口部６に取付けた際に，容器５の開口部６の外周面を囲んで配置される円筒形状のキャップ周壁部１０と，容器５の開口部６の上面を塞ぐ円盤形状のキャップ天板部１１を有している。キャップ周壁部１０の内周面には，容器５の開口部６の外周面に形成されたねじ部７と螺合するねじ部１２が形成されている。これら容器５の開口部６のねじ部７とキャップ周壁部１０の内周面のねじ部１２を螺合させることにより，ヒンジキャップ１（キャップ本体２）を，容器５の開口部６に対して脱着自在に取付けることができるようになっている。
【００１６】
キャップ天板部１１には，容器５に収納された粒状物を通過させる円形状の孔２０が形成されている。この孔２０は，容器５に収納された錠剤，カプセル等の粒状物一つ分の大きさよりも僅かに大きい直径を有している。このため，容器５に収納された粒状物は，この孔２０を一つずつ通過することができるようになっている。この実施の形態では，孔２０は，キャップ天板部１１の中心からヒンジ４と正反対の方向に僅かに離れた位置に配置されている。
【００１７】
キャップ天板部１１の下面には，円環状の肉厚部２１がキャップ天板部１１と一体的に形成されている。また，キャップ天板部１１の下面には，この円環状の突起２１の内側に近接して，キャップ天板部１１の下面よりも下方に突出する円筒状のキャップ本体支柱部２２がキャップ天板部１１と一体的に形成されている。更に，このキャップ本体支柱部２２の外周面には，円環状の肉厚部２３がキャップ本体支柱部２２（キャップ天板部１１）と一体的に形成されている。
【００１８】
容器５の開口部６のねじ部７とキャップ周壁部１０の内周面のねじ部１２を螺合させて，キャップ本体２を容器５の開口部６に取り付けた際には，キャップ天板部１１の下面に形成された円環状の肉厚部２１が容器５の開口部６の上面に隙間無く周方向に連続して押圧接触すると共に円筒状のキャップ本体支柱部２２が容器５の開口部６に挿入され，更に，キャップ本体支柱部２２の外周面に形成された円環状の肉厚部２３が容器５の開口部６の内周面に隙間無く周方向に連続して押圧接触するようになっている。そして，このように二つの円環状の肉厚部２１，２３を容器５の開口部６の上面及び内周面に隙間無くそれぞれ周方向に連続して押圧接触させることにより，容器５内部を密封するシール手段を構成している。
【００１９】
キャップ天板部１１の上面において，孔２０の周りには，孔２０に向って低くなる漏斗部２５が形成されている。また，キャップ天板部１１の上面には，この漏斗部２５の外側を囲む円筒形状の環状壁２６が形成されている。また，環状壁２６の外周面下部には，環状壁２６の外周面よりも外側に突出する円環状の肉厚部２７が形成されている。
【００２０】
キャップ天板部１１の下面には，キャップ天板部１１の下面よりも下方に突出し，かつ，孔２０を跨いで配置されたＵの字形状の邪魔棒３０が取り付けてある。この邪魔棒３０は，底部３１の両側に支柱部３２，３２を立設した構成を有し，支柱部３２，３２の上端が，孔２０を跨ぐように，キャップ天板部１１の下面において孔２０の近傍に取り付けられている。従って，容器５の内部から粒状物を孔２０から出す場合には，粒状物は，この邪魔棒３０の支柱部３２，３２間を通って孔２０に達することとなる。
【００２１】
邪魔棒３０の底部３１の上面には，上向きに突出する突起３５が設けてある。また，キャップ天板部１１の下面において孔２０の近傍には，キャップ天板部１１から下方に突出する一対の突起３６，３６が形成されている。前述の邪魔棒３０の支柱部３２，３２の上端が取り付けられている位置と直交する位置において孔２０を跨ぐように，これら突起３６，３６は孔２０を跨いで対向して配置されている。
【００２２】
キャップ天板部１１の下面において，孔２０の周りには，孔２０から離れた位置においてキャップ天板部１１から下方に突出する弧状のガイド突起４０，４１が，孔２０の一部を囲んで形成されている。この実施の形態では，孔２０に近い位置にある内側のガイド突起４０と，孔２０から遠い位置にある外側のガイド突起４１が，二列に配置されている。これらガイド突起４０，４１は，いずれも孔２０とヒンジ４の間の側において，孔２０の一部を囲むように配置されている。
【００２３】
蓋体３は，ヒンジキャップ１を閉じた際にキャップ天板部１１の上方に平行に配置される円盤形状の蓋体天板部５０と，蓋体天板部５０の周囲下方に配置される円筒形状の蓋体周壁部５１を有している。蓋体周壁部５１の内周面には，肉厚部５２が三箇所に形成されている。これら肉厚部５２は，中心角を１２０°として均一に配置されており，それらのうちの一つの肉厚部５２は，ヒンジ４と正反対の位置に配置されている。
【００２４】
ヒンジキャップ１を閉じた際には，蓋体周壁部５１の内周面に形成されたこれら肉厚部５２が，キャップ天板部１１の上面に形成された環状壁２６の外周面下部に形成された肉厚部２７の下方に入り込んだ状態となる。そして，これら肉厚部５２と肉厚部２７の係合によって，ヒンジキャップ１を閉じた状態が維持されるようになっている。
【００２５】
蓋体周壁部５１の外周面には，ヒンジ４と正反対の位置において，蓋体周壁部５１の外周面から外側に突出する突起５３が設けてある。ヒンジキャップ１を開く場合は，この突起５３を押し上げることにより，容易に開閉操作ができるようになっている。
【００２６】
蓋体天板部５０の下面には，ヒンジキャップ１を閉じた際に，キャップ天板部１１の孔２０に挿入される円筒形状の蓋体支柱部５５が，蓋体天板部５０と一体的に形成されている。蓋体支柱部５５の外周面は，下方に向って僅かに細くなるテーパー形状になっている。更に，この蓋体支柱部５５の下部の外周面には，円環状の肉厚部５６が蓋体支柱部５５（蓋体３）と一体的に形成されている。肉厚部５６の外周面の直径（外径）は，キャップ天板部１１に形成された孔２０の直径（内径）よりも僅かに大きく設定されている。このため，ヒンジキャップ１を閉じた際には，キャップ天板部１１の孔２０に挿入された蓋体支柱部５５の下部の外周面に形成された肉厚部５６が，孔２０の内周面に隙間無く周方向に連続して押圧接触するようになっている。そして，このように肉厚部５６を孔２０の内周面に隙間無く周方向に連続して押圧接触させることにより，ヒンジキャップ１を閉じた際に容器５内部を密封するシール手段を構成している。
【００２７】
蓋体天板部５０の下面において，蓋体支柱部５５の外側には，蓋体支柱部５５から外側に離れて位置において，蓋体支柱部５５を囲むように蓋体天板部５０の下面から下方に突出した円筒形状のストッパー５７が形成されている。このストッパー５７の高さ（蓋体天板部５０の下面からストッパー５７の下端までの距離）は，ヒンジキャップ１を閉じた際に，ストッパー５７の下端がキャップ天板部１１の上面よりも少しだけ上方に位置するように設定されている。
【００２８】
さて，以上のように構成された本発明の実施の形態にかかるヒンジキャップ１にあっては，キャップ本体２のキャップ周壁部１０の内周面に形成されたねじ部１２を，容器５の開口部６の外周面に形成されたねじ部７に螺合させることにより，ヒンジキャップ１（キャップ本体２）を，容器５の開口部６に対して脱着自在に取付けることができる。
【００２９】
そして，このようにヒンジキャップ１を容器５の開口部６に取付けた場合は，キャップ天板部１１の下面に形成された肉厚部２１が容器５の開口部６の上面に隙間無く周方向に連続して押圧接触すると共に，キャップ本体支柱部２２が容器５の開口部６に挿入され，更に，キャップ本体支柱部２２の外周面に形成された肉厚部２３が容器５の開口部６の内周面に隙間無く周方向に連続して押圧接触する。
【００３０】
そして，ヒンジキャップ１が閉じられている場合は，蓋体天板部５０の下面に形成された蓋体支柱部５５がキャップ天板部１１の孔２０に挿入され，蓋体支柱部５５の下部の外周面に形成された肉厚部５６が，孔２０の内周面に隙間無く周方向に連続して押圧接触している。こうして，ヒンジキャップ１が閉じられている間は，キャップ天板部１１の下面に形成されたシール手段である肉厚部２１，２３と，蓋体支柱部５５の外周面の下部に形成されたシール手段である肉厚部５６とにより，容器５の内部は密封された状態となっている。これにより，容器５の内部への外気の侵入が防がれ，錠剤の白斑化などといった粒状物の劣化が防止される。
【００３１】
また，このようにヒンジキャップ１が閉じられている場合は，蓋体周壁部５１の内周面に形成された肉厚部５２が，キャップ天板部１１の上面に形成された環状壁２６の外周面下部に形成された肉厚部２７の下方に入り込んだ状態となっている。これら肉厚部５２と肉厚部２７の係合により，ヒンジキャップ１は閉じた状態を維持する。
【００３２】
そして，ヒンジキャップ１を開ける場合は，蓋体３の蓋体周壁部５１の外周面に形成された突起５３を押し上げることにより，ヒンジ４を中心に蓋体３を上方に回動させ，容易に開けることができる。そして，ヒンジキャップ１を開けることにより，蓋体天板部５０の下面に形成された蓋体支柱部５５がキャップ天板部１１の孔２０から上方に抜き去られ，孔２０は開いた状態となる。
【００３３】
そして，容器５の開口部６を下に向けるように容器５を傾け，更に，必要であれば容器５を振るなどすることにより，容器５に収納されている錠剤，カプセル等の粒状物を，キャップ天板部１１に形成された孔２０から取り出すことができる。この場合，孔２０は，容器５に収納された錠剤，カプセル等の粒状物一つ分の大きさよりも僅かに大きい直径を有しているので，容器５に収納された粒状物を，孔２０に一つずつ通過させ，一つずつ取り出すことができる。
【００３４】
また，このように粒状物を取り出す際には，キャップ天板部１１の下面において孔２０の近傍に設けられた突起３６，３６によって，粒状物の過剰な落下を妨げ，たくさんの錠剤が孔２０を一気に連続して通過してしまうことを防ぐことができる。このため，粒状物を一つずつ取り出しやすく，希望する個数の粒状物だけを容器５から容易に取り出すことができる。
【００３５】
また，容器５の内部に乾燥剤などが粒状物と一緒に収納されている場合もある。そのような場合，通常，乾燥剤は粒状物よりも大きいものが使用されるので，乾燥剤は孔２０を通過できず，誤って容器５から乾燥剤が出てしまう心配がない。また，キャップ天板部１１の下面にはＵの字形状の邪魔棒３０が孔２０を跨いで配置されているので，乾燥剤がキャップ天板部１１の下面側から孔２０に密着することがない。このため，乾燥剤によって孔２０が塞がれる心配が無く，粒状物を容器５から円滑に取り出すことができる。
【００３６】
そして，容器５の内部に収納されている粒状物が残り少ないような場合であっても，キャップ天板部１１の下面において，孔２０の周りに形成されたガイド突起４０，４１の内側に沿って粒状物を移動させることにより，粒状物を孔２０に速やかに移動させ，容器５から容易に取り出すことができる。
【００３７】
一方，希望する個数を超える粒状物が容器５から出てしまった場合は，キャップ天板部１１に形成された孔２０を通して粒状物を容器５の内部に戻すことになる。この場合，キャップ天板部１１の上面には孔２０に向って低くなる漏斗部２５が形成されているので，粒状物を漏斗部２５において滑落させることにより，粒状物を孔２０に向って容易に移動させることができ，粒状物を容器５の内部に速やかに戻すことができる。
【００３８】
また，キャップ天板部１１の上面には漏斗部２５の外側を囲む環状壁２６が形成されているので，このように粒状物を容器５の内部に戻す場合，粒状物を環状壁２６の内側において移動させることにより，あやまって粒状物をキャップ天板部１１の上面から外に落下させる心配がない。
【００３９】
更に，粒状物を容器５の内部に戻す場合，孔２０を通過して容器５の内部に落下した粒状物が，Ｕの字形状をなす邪魔棒３０の底部３１の上に載ってしまうと，粒状物が詰り，後続の粒状物が容器５の内部に戻らなくなる可能性がある。しかし，邪魔棒３０の底部３１の上面に上向きに突出する突起３５が設けてある。このため，邪魔棒３０の底部３１の上に粒状物が載ろうとしても，突起３５で突上げられることにより不安定となり，邪魔棒３０の底部３１の上に粒状物が載ることはほとんどない。よって，粒状物が詰ることが無く，複数の粒状物でも連続して容器５の内部に戻すことができる。
【００４０】
そして，ヒンジキャップ１を閉じる場合は，蓋体３の蓋体天板部５０の上面を上から押さえることにより，ヒンジ４を中心に蓋体３を下方に回動させ，容易に閉じることができる，こうしてヒンジキャップ１を閉じた場合は，蓋体天板部５０の下面に形成された蓋体支柱部５５がキャップ天板部１１の孔２０に挿入され，蓋体支柱部５５の下部の外周面に形成された肉厚部５６が，孔２０の内周面に再び隙間無く周方向に連続して押圧接触した状態となり，キャップ天板部１１の下面に形成されたシール手段である肉厚部２１，２３と，蓋体支柱部５５の外周面の下部に形成されたシール手段である肉厚部５６とにより，容器５の内部は再び密封された状態となる。
【００４１】
このようにヒンジキャップ１を閉じる際に，蓋体３の蓋体天板部５０の上面を過剰な力で押し過ぎる場合もある。そのような場合，蓋体天板部５０の下面において，蓋体支柱部５５の外側を囲んで配置されたストッパー５７下端がキャップ天板部１１の上面に当接することにより，蓋体３の押し下げ過ぎを防止できる。このため，キャップ天板部１１の孔２０に対する，蓋体支柱部５５の挿入深さが一定に保たれる。これにより，蓋体支柱部５５の下部の外周面に形成された肉厚部５６を孔２０の内周面に確実に接触させ，肉厚部５６によって孔２０を密封できる状態を，繰り返して再現できるようになる。
【００４２】
また，このようにヒンジキャップ１が閉じられると，蓋体周壁部５１の内周面に形成された肉厚部５２が，キャップ天板部１１の上面に形成された環状壁２６の外周面下部に形成された肉厚部２７の下方に再び入り込んだ状態となる。これにより，ヒンジキャップ１は閉じた状態を再び維持する。
【００４３】
このように，本発明の実施の形態にかかるヒンジキャップ１によれば，閉じられている場合は，キャップ天板部１１の下面に形成されたシール手段である肉厚部２１，２３と，蓋体支柱部５５の外周面の下部に形成されたシール手段である肉厚部５６とにより，容器５の内部は密封された状態とされる。また，ヒンジキャップ１を開けて容器５に収納されている粒状物を孔２０から取り出す場合は，孔２０から粒状物を一つずつ取り出すことができ，希望する個数の粒状物だけを容器５から容易に取り出すことができる。更に，容器５の内部に収納されている粒状物が残り少ないような場合であっても，取り出しが容易である。
【００４４】
また，万が一希望する個数を超える粒状物を容器５から取り出してしまった場合であっても，粒状物を孔２０から容器５の内部に速やかに戻すことができ，戻す際にも，あやまって粒状物をキャップ天板部１１の上面から外に落下させる心配がない。そして，ヒンジキャップ１を再び閉じることにより，容器５の内部を密封された状態にもどすことができる。
【００４５】
このように，本発明の実施の形態にかかるヒンジキャップ１は，密封性に優れ，また，粒状物を容器５から取り出す作業も迅速にできるので，開いている時間も短くて済み，容器５の内部への外気の侵入を必要最小限に抑制でき，錠剤の白斑化などといった劣化が防止される。このヒンジキャップ１は，塩ビなどからなるパッキンを必要とせず，廃棄物を減少させることができるため，環境に与える影響が少ない。また，廃棄の際にパッキンを外すなどの面倒が無く，一体成型で容易に製作できるので，コスト低減できる。
【００４６】
以上，本発明の好ましい実施の形態を例示したが，本発明は以上に説明した形態に限定されない。例えば，例示した実施の形態では，キャップ天板部１１の下面に形成されるシール手段として，容器５の開口部６の上面に押圧接触する肉厚部２１と，容器５の開口部６の内周面に押圧接触する肉厚部２３を設けた例を説明したが，キャップ天板部１１の下面に形成されるシール手段として，これら肉厚部２１と肉厚部２３のいずれか一方のみを設けても良い。また，キャップ天板部１１の下面に形成されるシール手段として，肉厚部２１や肉厚部２３を設けず，容器５の開口部６の上面に，キャップ天板部１１の下面を押圧接触させ，あるいは，容器５の開口部６の内周面に，キャップ本体支柱部２２の外周面を押圧接触させて，密封するように構成しても良い。
【００４７】
また，例示した実施の形態では，蓋体支柱部５５の外周面に形成されるシール手段として，キャップ天板部１１の孔２０の内周面に押圧接触する肉厚部５６を設けた例を説明したが，蓋体支柱部５５の外周面に形成されるシール手段として，肉厚部５６を設けず，キャップ天板部１１の孔２０の内周面に，蓋体支柱部５５の外周面を押圧接触させて，密封するように構成しても良い。
【００４８】
また，図示の形態では，キャップ天板部１１の中心からヒンジ４と正反対の方向に僅かに離れた位置に孔２０を配置した例を示したが，孔２０は，例えばキャップ天板部１１の中心に配置しても良い。
【００４９】
また，図示の形態では，キャップ天板部１１の下面において，孔２０の一部を囲む弧状のガイド突起４０，４１を形成する例を示したが，孔２０から離れた位置において，孔２０の全周を囲むようなガイド突起４０，４１をキャップ天板部１１の下面に形成しても良い。また，ガイド突起は二列に限らず，一列でも良いし，三列以上でも良い。
【００５０】
また，容器５に収納される粒状物は，錠剤，カプセル等に限られず，種々の粒状物でも良い。
【００５１】
【実施例】
実施の形態で説明した本発明のヒンジキャップを実際に作成した。材質はポリプロピレンである。その結果，１ヶ月以上の長期間に渡って８〜１２Ｎの力で開封できるヒンジキャップを得ることができた。また，粒状物をほぼ一錠ずつ安定して取り出すことができた。
【００５２】
また，乾燥剤などによるつまりを防止するためにキャップ天板部の下面において孔を跨いで取付けられる邪魔棒の形状を種々検討した。その結果，Ｕの字形状，コの字形状，鉤型，山型，３方鉤型，３方十字型などを試したが，Ｕの字形状の邪魔棒が，粒状物の取り出し性，強度，成形性の何れにも勝っていた。
【００５３】
また，ヒンジキャップをポリエチレン瓶の容器の開口部に取付けて，ヒンジキャップを閉じた状態での気密性を調べた。容器に塩化カルシウムを２／３ほど入れ，４０℃，湿度７５％の恒温層に保存し，経時的に重量を測定した。その結果，本発明のヒンジキャップは，１〜６号までの各瓶サイズにおいて，従来のスクリューキャップとほぼ同等の気密性が得られていた。一方，従来例として他社製品のヒンジキャップについて気密性を調べたところ，その他社製品のヒンジキャップでは，容器内に相当量の水分が入り込み，本発明のヒンジキャップに比べて気密性がかなり劣っていた。
【００５４】
また，本発明のヒンジキャップを取りつけた容器に錠剤を収納したものと，従来のスクリューキャップを取りつけた容器に錠剤を収納したものについて，錠剤の白斑化に対する影響を調べた。その結果，本発明のヒンジキャップは錠剤を一つずつ取り出すことができるので所望の個数の錠剤のみを取り出すことができ，容器内に入り込む外気量も少なく抑えることができた。一方，従来のスクリューキャップは錠剤を出す際に容器の開口部全部が開放されてしまうため，容器内に入り込む外気量が多い。両者の白斑化した錠剤の数を比較したところ，乾燥剤を容器に収納している場合では，スクリューキャップでは８３個の錠剤が白斑化したのに対して，本発明のヒンジキャップでは１個の錠剤が白斑化したに過ぎなかった。また，乾燥剤を容器に収納していない場合では，スクリューキャップでは９５個の錠剤が白斑化したのに対して，本発明のヒンジキャップでは１２個の錠剤が白斑化したに過ぎなかった。
【００５５】
【発明の効果】
本発明によれば，開閉操作が容易なヒンジキャップにおいて，気密性を向上させることができる。また，本発明のヒンジキャップは，所望の数の粒状物を容器から取り出しやすく，過剰に出てしまった粒状物も容器内に戻しやすいので，開けている時間が必要最小限ですむ。そのため，容器内に入り込む外気量も少なくできる。

A cylindrical stopper 57 protruding downward is formed. The height of the stopper 57 (the distance from the lower surface of the lid top plate portion 50 to the lower end of the stopper 57) is such that when the hinge cap 1 is closed, the lower end of the stopper 57 is slightly smaller than the upper surface of the cap top plate portion 11. It is set so as to be located only above.
[0028]
Now, in the hinge cap 1 according to the embodiment of the present invention configured as described above, the screw portion 12 formed on the inner peripheral surface of the cap peripheral wall portion 10 of the cap main body 2 is connected to the opening of the container 5. The hinge cap 1 (cap body 2) can be detachably attached to the opening 6 of the container 5 by being screwed into a screw portion 7 formed on the outer peripheral surface of the portion 6.
[0029]
When the hinge cap 1 is attached to the opening 6 of the container 5 in this way, the thick portion 21 formed on the lower surface of the cap top plate portion 11 is circumferentially disposed on the upper surface of the opening 6 of the container 5 without a gap. The cap main body column 22 is inserted into the opening 6 of the container 5, and the thick portion 23 formed on the outer peripheral surface of the cap main column 22 is the opening 6 of the container 5. The inner circumferential surface is continuously pressed and contacted in the circumferential direction without a gap.
[0030]
When the hinge cap 1 is closed, a lid support column 55 formed on the lower surface of the lid top plate portion 50 is inserted into the hole 20 of the cap top plate portion 11, and A thick portion 56 formed on the outer peripheral surface of the hole 20 is in press contact with the inner peripheral surface of the hole 20 continuously in the circumferential direction without a gap. Thus, while the hinge cap 1 is closed, the thick portions 21 and 23 which are sealing means formed on the lower surface of the cap top plate portion 11 and the lower portion of the outer peripheral surface of the lid support column portion 55 are formed. The inside of the container 5 is hermetically sealed by the thick portion 56 which is a sealing means. Thereby, the intrusion of outside air into the inside of the container 5 is prevented, and deterioration of the granular material such as whitening of the tablet is prevented.
[0031]
Further, when the hinge cap 1 is closed in this manner, the thick portion 52 formed on the inner peripheral surface of the lid peripheral wall portion 51 is formed on the annular wall 26 formed on the upper surface of the cap top plate portion 11. It is in the state where it entered under the thick part 27 formed in the outer peripheral surface lower part. Due to the engagement of the thick part 52 and the thick part 27, the hinge cap 1 is kept closed.
[0032]
When opening the hinge cap 1, the projection 3 formed on the outer peripheral surface of the lid peripheral wall portion 51 of the lid 3 is pushed up to rotate the lid 3 upward about the hinge 4. Can be opened. Then, by opening the hinge cap 1, the lid support column portion 55 formed on the lower surface of the lid top plate portion 50 is pulled upward from the hole 20 of the cap top plate portion 11, and the hole 20 is opened. Become.
[0033]
Then, by tilting the container 5 so that the opening 6 of the container 5 is directed downward, and further shaking the container 5 if necessary, the granular materials such as tablets and capsules stored in the container 5 are obtained. It can be taken out from the hole 20 formed in the cap top plate portion 11. In this case, since the hole 20 has a diameter slightly larger than the size of one granular material such as a tablet or a capsule stored in the container 5, the granular material stored in the container 5 is replaced with the hole 20. Can be passed one by one and taken out one by one.
[0034]
Further, when taking out the granular material in this way, excessive protrusion of the granular material is prevented by the projections 36, 36 provided in the vicinity of the hole 20 on the lower surface of the cap top plate portion 11, and a large number of tablets are formed in the hole 20. Can be prevented from passing continuously. Therefore, it is easy to take out the granular materials one by one, and only the desired number of granular materials can be easily taken out from the container 5.
[0035]
In some cases, a desiccant or the like is stored in the container 5 together with the granular material. In such a case, since the desiccant is usually larger than the granular material, the desiccant cannot pass through the holes 20 and there is no fear that the desiccant will accidentally come out of the container 5. Further, since the U-shaped baffle rod 30 is disposed across the hole 20 on the lower surface of the cap top plate portion 11, the desiccant may come into close contact with the hole 20 from the lower surface side of the cap top plate portion 11. Absent. For this reason, there is no fear that the hole 20 is blocked by the desiccant, and the particulate matter can be smoothly taken out from the container 5.
[0036]
Even when the amount of granular material stored in the container 5 is small, along the inside of the guide protrusions 40 and 41 formed around the hole 20 on the lower surface of the cap top plate portion 11. By moving the granular material, the granular material can be quickly moved to the hole 20 and easily taken out from the container 5.
[0037]
On the other hand, when the particulate matter exceeding the desired number has come out of the container 5, the particulate matter is returned to the inside of the container 5 through the hole 20 formed in the cap top plate portion 11. In this case, a funnel portion 25 that is lowered toward the hole 20 is formed on the upper surface of the cap top plate portion 11, so that the particulate matter can be easily moved toward the hole 20 by sliding the particulate matter at the funnel portion 25. The granular material can be quickly returned to the inside of the container 5.
[0038]
Further, since an annular wall 26 surrounding the outside of the funnel portion 25 is formed on the upper surface of the cap top plate portion 11, when returning the particulate matter to the inside of the container 5 in this way, the particulate matter is placed inside the annular wall 26. Therefore, there is no fear that the particulate matter is accidentally dropped from the upper surface of the cap top plate portion 11.
[0039]
Furthermore, when returning the granular material to the inside of the container 5, if the granular material that has passed through the hole 20 and dropped into the container 5 is placed on the bottom 31 of the baffle rod 30 having a U-shape, There is a possibility that the particulate matter is clogged and the subsequent particulate matter cannot be returned to the inside of the container 5. However, a protrusion 35 protruding upward is provided on the upper surface of the bottom 31 of the baffle rod 30. For this reason, even if a granular material tries to be placed on the bottom portion 31 of the baffle rod 30, it becomes unstable by being pushed up by the protrusion 35, and the granular material is hardly placed on the bottom portion 31 of the baffle rod 30. Therefore, the granular material is not clogged, and a plurality of granular materials can be continuously returned to the inside of the container 5.
[0040]
When the hinge cap 1 is closed, the lid body 3 can be pivoted downward about the hinge 4 and easily closed by pressing the upper surface of the lid top plate portion 50 of the lid body 3 from above. In this way, when the hinge cap 1 is closed, the lid support column 55 formed on the lower surface of the lid top plate portion 50 is inserted into the hole 20 of the cap top plate portion 11, and the outer periphery of the lower portion of the lid support column portion 55. The thick portion 56 formed on the surface is in a state where it is continuously pressed in contact with the inner peripheral surface of the hole 20 in the circumferential direction again without a gap, and the thick portion which is a sealing means formed on the lower surface of the cap top plate portion 11. The inside of the container 5 is again sealed by the portions 21 and 23 and the thick portion 56 which is a sealing means formed at the lower portion of the outer peripheral surface of the lid support column portion 55.
[0041]
Thus, when closing the hinge cap 1, the upper surface of the lid top plate portion 50 of the lid 3 may be pushed too much with an excessive force. In such a case, the lower end of the stopper 57 disposed so as to surround the outer side of the lid support column 55 on the lower surface of the lid top plate portion 50 abuts on the upper surface of the cap top plate portion 11, thereby pushing down the lid 3. It can be prevented. For this reason, the insertion depth of the lid support column 55 with respect to the hole 20 of the cap top plate 11 is kept constant. As a result, a state in which the thick portion 56 formed on the outer peripheral surface of the lower portion of the lid support column 55 is brought into contact with the inner peripheral surface of the hole 20 and the hole 20 can be sealed by the thick portion 56 is repeatedly reproduced. become able to.
[0042]
When the hinge cap 1 is closed in this way, the thick portion 52 formed on the inner peripheral surface of the lid peripheral wall portion 51 becomes the lower portion of the outer peripheral surface of the annular wall 26 formed on the upper surface of the cap top plate portion 11. It will be in the state which entered again below the thick part 27 formed in this. Thereby, the hinge cap 1 maintains the closed state again.
[0043]
As described above, according to the hinge cap 1 according to the embodiment of the present invention, when closed, the thick portions 21 and 23 that are sealing means formed on the lower surface of the cap top plate portion 11, the lid The inside of the container 5 is sealed by a thick portion 56 which is a sealing means formed at the lower part of the outer peripheral surface of the body support portion 55. Further, when opening the hinge cap 1 and taking out the granular material stored in the container 5 from the hole 20, the granular material can be taken out one by one from the hole 20, and only a desired number of granular materials can be removed from the container 5. It can be easily taken out. Furthermore, even if there is little remaining granular material stored in the container 5, it can be easily taken out.
[0044]
Further, even if a particulate matter exceeding the desired number is taken out from the container 5, the particulate matter can be quickly returned to the inside of the container 5 from the hole 20, and when it is returned, There is no worry of dropping an object from the top surface of the cap top plate 11. And the inside of the container 5 can be returned to the sealed state by closing the hinge cap 1 again.
[0045]
As described above, the hinge cap 1 according to the embodiment of the present invention is excellent in sealing performance, and can quickly remove the granular material from the container 5, so that the opening time can be shortened. Intrusion of outside air into the interior can be suppressed to the minimum necessary, and deterioration such as whitening of tablets can be prevented. The hinge cap 1 does not require packing made of polyvinyl chloride and the like, and can reduce waste, so it has little influence on the environment. In addition, there is no hassle of removing the packing at the time of disposal, and it can be easily manufactured by integral molding, so the cost can be reduced.

In addition, the effect on the whitening of the tablet was examined for the case where the tablet was stored in the container with the hinge cap of the present invention and the case where the tablet was stored in the container with the conventional screw cap. As a result, the hinge cap of the present invention can take out tablets one by one, so that only a desired number of tablets can be taken out, and the amount of outside air entering the container can be reduced. On the other hand, since the conventional screw cap opens the entire opening of the container when taking out tablets, the amount of outside air entering the container is large. Comparing the number of the whitened tablets in both cases, when the desiccant was stored in the container, 83 tablets were whitened in the screw cap, whereas in the hinge cap of the present invention, one tablet was obtained. The tablet only became vitiligo. In the case where the desiccant was not stored in the container, 95 tablets were whitened with the screw cap, whereas only 12 tablets were whitened with the hinge cap of the present invention.
