Description

【０００１】
【発明の属する技術分野】
本発明はキャップに関する。
【０００２】
【従来の技術】
キャップとして、容器体口頚部外周に嵌合させた周壁上端縁より注出口付きの頂板を延設した本体と、本体後部に後部を弾性反転可能に連結するとともに、頂壁裏面より垂設した棒栓を注出口に密嵌させた蓋体とを備えたものが一般に知られている。また、これらキャップは、蓋体前面に突設した指掛け突起に指をかけて開蓋を行うのが一般的である。
【０００３】
【発明が解決しようとする課題】
上記従来のキャップにおいて注出口は一般に短筒状に形成されており、該短筒部分内面に棒栓外面を密嵌し、この部分の液密性を付与している。従って、より充分な液密性を得るためにはこの部分がより密に嵌合していればよいわけであるが、反面開蓋の際には強い力を必要としてあけずらくなる。特に片手での開蓋はシール性が上がれば上がる程行いずらくなる。
【０００４】
本発明は上記した点に鑑みなされたもので、強い力を必要とせずに簡単に開蓋することができ、片手での容易な開蓋も可能であり、しかも、注出口部分の充分な液密性を備えた優れたキャップを提案するものである。
【０００５】
【課題を解決するための手段】
本請求項１発明のキャップは、上記課題を解決するため、容器体５の口頚部６外周に嵌合させる嵌合筒７上端縁より頂板８を延設するとともに、頂板８に注出口９を設けてなる本体２と、本体２後部に後部を回動可能に連結するとともに、頂壁16裏面より垂設した棒栓17を注出口９に密嵌させた蓋体３とを備えたキャップに於いて、蓋体頂壁16に窓孔22を穿設するとともに、窓孔22内側縁部分の頂壁縁部に内側上端縁を回動可能に連結して内外方向揺動可能に垂下させた筒部23を設け、該筒部を貫通して嵌合させた脚部26を、蓋体頂壁16上に載置した押上板27の下面より垂設してなる開蓋部材４を設け、蓋体頂壁16外方へ突出させた押上板27外側縁部を上方へ押し上げることにより、本体頂板８上に突設した突起15上を脚部26下端部が摺動上昇して開蓋する如く構成したことを特徴とするキャップとして構成した。
【０００６】
【発明の実施の形態】
以下、本発明の実施例の形態を図面を参照して説明する。
【０００７】
本発明のキャップ１は、本体２と、蓋体３と、開蓋部材４とを備えている。
【０００８】
本体２は合成樹脂により形成されたもので、容器体５の口頚部６外周に嵌合させる嵌合筒７上端縁より頂板８を延設し頂板８に注出口９を穿設している。注出口９は、後述する棒栓が密嵌出来る形態であれば種々の形態が採用できる、図示例では、頂板８前部の偏心位置に基端を開口して上方へ起立した短筒状をなしており、内面上部にテーパ部10を設けて棒栓をより密嵌し易いよう構成している。但し、注出口の構成はこれに限られず、単に頂板８に穿孔した注出口であっても良く、その穿設位置も偏心位置に限らず、中心位置に設けても良い。
【０００９】
図示例では、口頚部６外周に突設した係止突条11下面に、嵌合筒７内周に突設した係合突条12を乗り越え係合させて上方への抜け出し防止を図っている。また、口頚部６内面に密嵌させたシール筒13を頂板８裏面より垂設し、この部分から液の漏出防止を図っている。更に、頂板８上面周縁部には蓋体３を嵌合させるための環状凹部14を凹設している。
【００１０】
また、頂板８上面の所定位置には突起15を突設している。突起15の具体的形状は、脚部の回動に伴いその下端部が摺動上昇できる形態であれば種々採用でき、図示例では、後方へ下る傾斜面S1を有する側面視三角形状をなす平面視横長矩形状の突起15を採用している。突起15はこの外に脚部下端部が摺動上昇できる湾曲面をもつもの等を採用できる。
【００１１】
蓋体３も合成樹脂により形成されたもので、本体２後部に後部を回動可能に連結するとともに、頂壁16裏面より垂設した棒栓17を注出口９に密嵌させる如く構成した伏皿状のものが採用できる。図示例では上記環状凹部14に下端縁を嵌合させた周壁18上端縁より頂壁16を延設するとともに、周壁18後部下端部を本体後部上端部に薄肉ヒンジ19を介して回動可能に連結し、また、薄肉ヒンジ19の両側に於いて、本体２の嵌合筒７上部と蓋体周壁18下部とを結ぶ円弧状の弾性板20をそれぞれ一体に架設し、蓋体３を弾性反転可能に構成している。棒栓17は、注出口９に離脱可能に密嵌させる形態のものであれば良く、図示例の如く、中空の筒状に形成しても、中実の棒状であっても良いが、筒状のものは微妙な変形が可能であるため、より液密性を得るために好ましい。また、棒栓17周囲の頂壁16裏面には、前部を開口した円弧状壁21を垂設している。
【００１２】
蓋体３の頂壁16には窓孔22を穿設し、窓孔22内側縁部の頂壁16縁部に内側上端縁を回動可能に連結して内外方向揺動可能に垂下させた筒部23を設けている。窓孔22や筒部23の形状は特に限定されないが、筒部23の内外方向の揺動が可能な程度に窓孔22を大きく形成する。図示例では、棒栓17前方に横長四角形状の窓孔22を穿設し、窓孔22後縁部分の頂壁16縁部に上端後縁をヒンジ部24を介して回動可能に連結した上下端開口の四角筒状をなす筒部23を設けている。図示例の筒部23は、揺動させるためのヒンジ部24の幅がある程度長く形成できて一定方向の安定した揺動が可能となる如く構成している。ヒンジ部24は弾性復元力をもつ程度の肉厚或いは材質或いは肉厚と材質を選択すれば、押し上げた押上板27が自動的に元に戻り好ましい。また、筒部23の内周下端部には係合突条部25を突周設している。尚、窓孔22は棒栓17垂設部分を除く頂壁16部分に穿設でき、それに合わせて突起15の位置を決めることができる。
【００１３】
開蓋部材４も合成樹脂により形成されたもので、筒部23を貫通して嵌合させた脚部26を、蓋体頂壁16上に載置した押上板27の下面より垂設して構成している。また、蓋体頂壁16外方へ突出させた外側縁部を上方へ押し上げることにより、本体頂板８上に突設した上記突起15上を脚部26下端部が摺動上昇して蓋体を押し上げ、開蓋する如く構成している。
【００１４】
本実施例の開蓋部材４は、図３〜図５に示す如く、四角板状の押上板27の後部中央より横断面矩形状で下面を傾斜面S2とした脚部26を垂設している。脚部26の外周下部には上記係合突条部25が嵌合する環状凹溝28を周設している。また、押上板27下面外周縁部分には蓋体頂壁16周縁部に係合させる円弧状の枠状突起29を突設している。
【００１５】
この様な開蓋部材４を図１に示す如く、その脚部26を筒部23を貫通して嵌合させるとともに、脚部26の下面である傾斜面S2を本体２の突起15上面である傾斜面S1に当接載置し、また、頂壁16上面前端部に、その前端縁部を頂壁16前方へ突出させて、押上板27を載置している。その際、枠状突起29が蓋体前部コーナー部分に係合している。脚部26の環状凹溝28には、図６に拡大図で示す如く、筒部23の係合突条部25を嵌合させて抜け出しを防止している。
【００１６】
上記の如く構成したキャップ１を使用する場合に付いて一例を説明すると、まず、図１の状態から押上板27の突出部分を上方へ押し上げると、ヒンジ部24を中心として筒部23がその下端を前方へ移行する如く回動し、同時に脚部26が回動する。その際、脚部26の傾斜面S2先端縁が突起15の傾斜面S1上を摺動上昇し、蓋体３前部を押し上げて棒栓17を注出口９から外す（図７（ａ））。尚、同図では棒栓17が完全に外れていないが、最初の密嵌状態と比較して小さな力で外れる状態となっている。次いで、なおも押上板27を押し上げると、棒栓17が注出口から完全に外れ、弾性反転機構により蓋体３が反転し開蓋状態を維持する（図６（ｂ））。
【００１７】
【発明の効果】
以上説明した如く本発明キャップは、既述構成としたことにより、強い力を必要とせずに簡単に開蓋することができ、片手での容易な開蓋も可能であり、しかも、注出口部分の充分な液密性を備えている。
