【０００９】
【発明の実施の形態】
以下図面について説明すると、１はキャップ本体であり、該キャップ本体は、左右方向へ長い楕円形状としており、小ノズル２を起立する頂板３から、図２が示すように容器体口頸部の外面へ嵌合させる内筒４と該内筒４を囲んで外筒５を垂下し、外筒上端部は図１のように上向き段部６を介して小外径部７に形成している。内筒４は口頸部嵌合のため眞円としており、外筒５は楕円形状をなす。上記小ノズル２は半球形状をなし、その上部前面を斜面として該斜面中心に注出孔２ａを開口させている。８は口頸部内面へ嵌合させるシール筒である。
【００１０】
又キャップ本体は左右両部の外筒５上部および頂板部分を凹部９，９に形成して、これ等凹部の底面を透孔１０，１０付きで上内方への傾斜面１１，１１とする。傾斜面は透孔１０の前後両側に形成しており、図示例において透孔内縁は凹部奥壁１２の下部まで穿設している。透孔下縁には突部１３，１３を付設する。
【００１１】
２１は蓋体で、該蓋体はキャップ本体１の後方上部へヒンジ２２を介して連結させている。該ヒンジは弾性反転可能なヒンジで行うとよく、該ヒンジを中心とする回動により蓋体２１はキャップ本体上面へ嵌合可能に形成する。該嵌合時において、頂壁２３外周から垂下する周壁２４下部を小外径部７外面へ嵌合させ、又周壁下端面を上向き段部６上面へ載置可能にしている。該蓋体もキャップ本体と同様に平面楕円形状としている。該蓋体は既述小ノズル２外面へ嵌合させて注出孔２ａを密閉できる小筒部２５を頂壁２３下面から垂下する。
【００１２】
蓋体２１は、周壁２４左右両部の前後を切離し線２６，２６で切離し、かつ下方へ延長して上記凹部９，９内へ嵌合する弾性板２７，２７としており、又これ等弾性板下端から透孔１０，１０内へ挿通させてフック２８，２８を垂下する。該フックは図２が示すように既述透孔下縁の突部１３，１３へ係合させる。図示のように弾性板下部は凹部外方へ張出しさせて押釦状部２９，２９に形成することが望ましい。
【００１３】
図２が示す閉蓋状態から図３のように弾性板２７，２７を内方へ押すと、フックが外れると同時に弾性板下面が傾斜面１１，１１に沿って押上げられることとなり、よって蓋体は押上げられることとなるから、そのまま蓋体を開けばよい。開蓋状態から蓋体を閉めると、フック２８，２８下端面が突部１３，１３上面へ接し、フック下端に形成した斜上外方への斜面ないし透孔下縁の突部１３，１３上面へ設けた斜下外方への斜面によりフック２８，２８は透孔１０，１０内へ入って突部１３，１３へ係合する。
【００１４】
以下他の実施形態について説明するが、第１実施形態と同一部分については同一符号を付することで説明を省略する。
【００１５】
図４は第２実施形態を示すもので、第１実施形態の凹部９、蓋体周壁の弾性板２７をそれぞれキャップ本体の前部および蓋体周壁の前部に設けるものである。
【００１６】
図５から図８は第３実施形態を示す。該実施形態は、キャップ本体上向き段部６を、特に左右両部を巾広に形成して透孔３１，３１を穿設し、又該透孔の前後側方に外端部上面を内方への上昇斜面３２，３２とする乗上げ突条３３，３３を横設している。透孔３１は図６が示すようにその外縁へ係合突条３４，３４を付設させており、乗上げ突条外端と上向き段部６外縁との間には蓋体周壁載置用の小間隙を形成させている。尚図示例において小外径部７は中間上向き段部６ａを介して下方小外径部７ａと上方小外径部７ｂとで形成しており、上記乗上げ突条３３，３３は下方小外径部外面から上面を面一として突出させ、上方小外径部７ａ外面へ後述蓋体頂壁から垂設した内周壁４８下端を嵌合させている。
【００１７】
蓋体２１は図５が示すように周壁２４の左右両部上端に切離し線４１，４１を穿設してこれ等切離し線下方の周壁部分を半筒状の板バネ４２，４２としている。又図６が示すようにこれ等両板バネ中間部の下端内面からは、既述透孔３１，３１内へ遊挿させてフック４３，４３を垂下させ、これ等フックを透孔３１，３１外縁へ付設した係合突条３４，３４へ係合させている。又これ等フック側方の周壁下端部分内面へは、図７が示すように既述上昇斜面３２，３２上へ乗上げさせる摺動子４３ａ，４３ａを付設しているが、これ等摺動子は必ずしも必要ではなく、蓋体周壁下端面が直接上昇斜面３２，３２上へ乗上げるようにしてもよい。尚前後いずれかの乗上げ突条および摺動子のうちの一方は省略することが出来る。更に両板バネ中間部上方の頂壁部分を、板バネの内方押込みが可能に切欠き４４，４４させ、かつこれ等両切欠き上面を閉塞させて、板バネ中間部上端から覆合板４５，４５を内方へ突出させている。これ等覆合板の内方部分へは、図５、図６が示すように上記覆合板を摺動させる摺動溝４６，４６を穿設している。これ等覆合板基部にも透孔４７，４７を穿設しているが、これ等は既述のフック成形時のための型抜き用透孔で必ずしも必要としない。
【００１８】
蓋体頂壁の下面からは既述上方小外径部７ｂ外面へ嵌合させて内周壁４８を垂下し、又ノズル外面へ嵌合させて注出孔を密閉させる小筒部２５を垂下する。
【００１９】
上記構成において、図５、図６が示す閉蓋状態から板バネ４２，４２の左右中間部を内方押込みすると、図６のフック４３，４３が係合突条３４，３４から外れると同時に図７が示す摺動子４３ａ，４３ａが上昇斜面３２，３２上へ乗上げることで蓋体２１はヒンジ２２を中心に押上げられることとなり、よって該状態から容易に開蓋できる。押圧解放により板バネ４２，４２が弾性復元し、該開蓋状態からの閉蓋で、フック２８，２８は、フック下端面ないし係合突条３４，３４上面の斜面を滑動して係合突条３４，３４へ係合する。
【００２０】
図９は第４実施形態を示す。該実施形態は第３実施形態が左右一対として設けていた透孔３１、上昇斜面３２付きの乗上げ突条３３、板バネ４２、フック４３等の蓋体押上げ機構を、キャップの前部だけに設けたもので、第３実施形態と同一符号を付することで説明は省略する。従って該実施形態にあっては、蓋体周壁前部が形成する板バネ４２を後方押込みすることで、蓋体前部が上昇して開蓋でき、又蓋体押下げで閉蓋できる。
【００２１】
既述キャップ本体と蓋体とは、合成樹脂材で一体成形している。
【００２２】
尚既述注出孔２ａと、該注出孔を密閉する蓋体頂壁の密閉部とは、どのように行ってもよく、例えば注出孔２ａを頂板３に直接穿設し、又蓋体下面から閉塞栓を垂下させて、閉蓋時に密閉され、開蓋により開孔するようにすることが考えられる。
【００２３】
【発明の効果】
本発明は既述構成とするもので、各請求項の場合、弾性板２７ないし板バネ４２を内方押込みしない限り、開蓋できないこととなり、従って幼児等による開蓋を防止して不測の事態を防止できる。
【００２４】
請求項１記載のようにすることで、弾性板２７，２７内方押込みで弾性板下端面が傾斜面１１，１１に沿い上昇することで容易に開蓋できる。
【００２５】
請求項２のようにすることで、上記請求項１の蓋体押上げ機構をキャップ前部だけに設ければよいこととなり、よってキャップの構造を簡易化できる。
【００２６】
請求項３のようにすることで、板バネ４２，４２の内方押込みで容易に開蓋でき、又板バネの肉厚、長さ等の調整で、幼児等にとっては弾性変形させ難く、かつ大人にとっては弾性変形可能にすることが容易である。
【００２７】
請求項４のようにすることで、請求項３の開蓋機構をキャップの前部にだけ設ければよく、よって構造を簡易化できる。
