Description

【０００１】
【発明の属する技術分野】
本発明は、エアゾール式の液体噴出容器に関する。
【０００２】
【従来の技術】
容器体頂壁に貫通させて容器体上部内からステムを上方付勢させて起立すると共に、該ステム上部へノズル付き押下げヘッドから垂下させたノズル連通筒下部を嵌合させ、又容器体上部外面へ下方筒部を嵌合させて起立させた囲成筒上部内へ、押下げヘッド外周部から垂下させた外周壁下部を嵌合させ、容器体および囲成筒に対する押下げヘッド押下げによってステムの下部に設けた吐出弁が開いて、容器体内液体が上記ステム、ノズル連通筒、ノズルを通って外方へ噴出可能とする、エアゾール式液体容器が広く市販されている。
【０００３】
【発明が解決しようとする課題】
本発明は、上記従来の容器にロック機構と容器廃棄時に行うガス抜き機構とを持たせて、不用意に押下げヘッドが押されて液体噴出するがないようにすると共に、廃棄に際してはガス抜きをして廃棄物回収車内等でのガス爆発による事故を防止できるよう設けたものである。
【０００４】
【課題を解決するための手段】
第１の手段として、容器体頂壁に貫通させてかつ上方付勢させて、容器体上部内からステム５を起立すると共に、該ステムの上部へ、ノズル13付き押下げヘッド11から垂設したノズル連通筒12を嵌合させ、又容器体上部外面へ下方筒部を嵌合させて起立させた囲成筒21の上部内面へ、上記押下げヘッド11から垂下させた外周壁15を下降可能に嵌合させ、上記押下げヘッド11を付勢に抗して容器体および囲成筒21に対して押下げることで、ステム５下端部に設けた吐出弁が開いて容器体内液体がステム、ノズル連通筒、ノズルを通って噴出可能とするエアゾール式液体噴出容器において、
上記押下げヘッド11の一部から係合板16を垂下させて該係合板下部を上記囲成筒21の下部内面に付設した内向きフランジ25の透孔26内へ遊挿させ、又該係合板の下部側面にはフック17を、又該フックを有しない側の下部側面には切欠き18を設けておき、
上記付勢に抗して押下げヘッドをほぼ下限まで押し下げた状態から容器体に対して押下げヘッド11又は囲成筒21を回すことで透孔26の周縁部下面へフック17が係合して押下げヘッドをほぼ下限に位置させることが可能とすると共に、押下げヘッドが上限に位置する状態から押下げヘッド又は囲成筒21を他方へ回すことで、切欠き18下面が、透孔26周縁部の上面へ載置して内向きフランジ25に対する押下げヘッド11の下降が不能とした。
【０００５】
第２の手段として、上記第１の手段を有すると共に、上記フック17の先端部から係合突部19を起立させると共に、フック17が突出する側の透孔26の側縁部からストッパ27を垂下させ、押下げ時における押下げヘッドないし囲成筒21の回動によって上記係合突部19がストッパ27へ係合可能に形成した。
【０００６】
【発明の実施の形態】
以下図面について説明すると、１は公知のエアゾール容器体で該容器体は胴部２上端からなで形状の肩部３を起立し、該肩部上端と容器体上面を閉塞する頂壁外周とを共に巻締め４し、又その頂壁中央部を貫通させて容器体上部内からステム５を上方付勢させて起立する。尚そのステム下端部には吐出弁が設けられていて、付勢に抗してステムが押下げられることで容器体内液体がそのステム内を通って噴出可能としている。
【０００７】
11は押下げヘッドで、該ヘッドは上記ステム５上部へ嵌合させたノズル連通筒12上端から、ノズル13を側外方へ屈曲させ、又先端部を除くノズル上方筒部分を頂壁前部と共用させて頂壁14を設け、該頂壁外周から外周壁15を垂下している。該外周壁の後部下端からは既述ロック機構とガス抜き機構とを形成するための係合板16を垂下するが、該係合板については後述する。
【０００８】
21は容器体１の上部外面へ下方筒部を嵌合させた囲成筒で、上面閉塞で下面開口の内外二重筒とし、該二重筒前部の上半部は内筒だけの一重筒とし、かつ該一重筒部分のノズル下方部分を切欠きしている。内筒22下端は既述容器体の巻締め部分外面へ嵌合させてその下端内面に周設した係合突条23を巻締め４下面へ係合させて囲成筒21が上方抜出しすることを防止し、又外筒24下端は容器体の肩部３上面へ当接させている。又内筒22の上下方向中間部には内向きフランジ25を付設し、そのフランジ孔内へノズル連通筒12下部を遊挿させている。又該内向きフランジ後部には透孔26を穿設して既述係合板16下端部を図３のように遊挿させている。
【０００９】
既述係合板16は図３が示すように、係合板下方一方の側部からフック17を突出し、又該フックを有しない側の係合板下部には切欠き18を設け、図４が示すように囲成筒21に対して上限に位置する状態から押下げヘッド11を回動させることで切欠き18の上面が透孔26側部の内向きフランジ部分上面へ、又図３の状態から押下げヘッドをほぼ下限まで押下げ、かつ上記回動方向と反対方向へ押下げヘッドを回すことでフック17が透孔周辺部下面へ、それぞれ係合するよう設けている。
【００１０】
切欠き18上面を透孔26側部の上面へ係合させることで、押下げヘッドをロック、つまり押下げ不能とすることが出来、又押下げ状態からの回動でフック17上面を透孔周辺部下面へ係合させることで、ガス抜きを行うことが出来る。
【００１１】
上記ガス抜き操作を行う際、押下げヘッド11を下限まで押下げし、かつ回動させた際、ステム５を上方付勢させているコイルスプリングに捩れが生じ、その復元により一たん透孔周辺部下面へ係合させたフック17が再びその下面から外れることがある。
【００１２】
このような場合は図６から図８が示すようにフック先端から係合突部19を起立させると共に、フック突出側の透孔26周辺部からはストッパ27を垂下させておき、押下げヘッドを押下げかつ回動させた際に係合突部19がストッパ27に係合して外れないよう設けるとよい。
【００１３】
尚図示例においては係合板16を押下げヘッド外周壁15の後部下面から垂下させたが、その外周壁の他部下面から垂下させてもよく、又押下げヘッドの頂壁下面から垂下させてもよい。この場合、透孔26はその係合板下方に穿設することとなる。
【００１４】
上記構成において、図１の状態から容器体内液体を噴出させるときは、図３、図６が示すように切欠き18およびフック17が透孔26の上方ないし透孔内に位置するよう設けてそのまま押下げヘッド11を押下げすればよい。すると押下げヘッド11はステム５の付勢に抗して下限まで押下げられてステム下端の吐出弁が開くことで容器体内液体はステム５、ノズル連通筒12、ノズル13内を通って外方へ噴出する。
【００１５】
押下げヘッドの押下げが不能にロックする場合は、図３および図６が示す、押下げヘッド11が上限に位置する状態から、容器体に対して押下げヘッドないし囲成筒21を回すことで図４、図７のように係合板16の切欠き上面を透孔26側方の内向きフランジ部分上面へ係合させ、該状態では押下げヘッド11の押下げが不能とする。
【００１６】
容器体内液体が無くなり、容器体を廃棄する際には、押下げヘッドが上限に位置する位置から押下げヘッド11をほぼ下限まで押下げ、かつ図５、図８のように容器体に対して押下げヘッド11ないし囲成筒21を上記と逆方向へ回すことでフック17を透孔26の周辺部下面ないしストッパ27下面へ当てて係合突部19をストッパ27に係合させる。該押下げヘッド下限位置ではステム５下端部に設けた吐出弁が開いているため、容器体内のガスはステム５、ノズル連通筒12、ノズル13内を通って無くなるまで放出し続けることとなる。
【００１７】
【発明の効果】
本発明は既述構成としたから、請求項１のようにすることで、押下げヘッドの押下げを不能として不用意に容器体内液体が噴出することを防止できると共に、廃棄時には容器体内のガス抜きも出来、それ等操作も簡易に行うことが出来る。
【００１８】
請求項２のようにすることで、ガス抜きの途中でストッパ27からフック17が外れてガス抜きが中断することがなく、確実に容器体内の全ガスを放出させることが出来る。
