Description

【０００１】
【発明の属する技術分野】
本発明は、トリガー式液体噴出器のロック装置に関するものである。
【０００２】
【従来の技術】
液体を噴霧、噴射、噴泡等させる合成樹脂製のトリガー式液体噴出器は既に周知である。
このトリガー式液体噴出器は、通常、側面形状逆Ｌ字状の噴出器本体を設け、該噴出器本体の先端にノズルを設け、該ノズルには回動により噴霧、噴射、噴泡等と停止（閉路）を切替え得るノズルキャップを装着し、また、噴出器本体の前部からトリガーを前後動可能に垂設し、噴出器本体の内部に該トリガーで作動される往復ポンプを内蔵するとともに、該往復ポンプにトリガー共々出方向に付勢する復帰ばねを備えている。
而して、噴出器本体の下端の装着筒により液体を収容した容器体の口頸部に取り付けるとともに、噴出器本体から垂下した吸上パイプをその容器体内へと挿入し、ノズルキャップを噴霧、噴射、噴泡等の所要噴出態勢に回動した後、トリガーを操作して往復ポンプを作動させ、容器体内の液体を吸い上げてはノズルから噴霧、噴射、噴泡等、適宜に噴出させる。
【０００３】
【発明が解決しようとする課題】
しかし、ノズルキャップを停止位置にして、ノズルを閉じた状態にしただけでは、次のような問題がある。
▲１▼ 既に使用が開始されているものであっても、ポンプ内には液体だけでなく構造上から不可避的に残留するわずかな空気も存在するため、ノズルを閉じたままトリガーが操作されると、その残留空気が圧縮されることで更に液体が吸い上げられ、ポンプ内には相応の圧力で液体が蓄圧貯留されることとなる。
したがって、この状態でノズルキャップを所要噴出態勢に回動させると、ノズルが開路した途端に、該ノズルから不意にポンプ内の蓄圧貯留液体が噴出する。
▲２▼ 近年、一般家庭でも、かび落し等の洗浄剤がこの種トリガー式液体噴出器を利用して使用されるようになってきているが、このような洗浄剤が上述のようにして不意に噴出すると、甚だ危険である。
▲３▼ うっかりノズルキャップを所要噴出態勢に回動させるのを忘れてトリガーを操作した場合、故障と勘違いすることがある。また、これが頻繁に繰り返されると故障の原因にもなりかねない。
【０００４】
そこで、本発明は、ノズルキャップのノズルを閉路させた停止態勢において、ノズルキャップから突出したレバーの係止手段でトリガーを機械的自動的にロックすることで、トリガーの誤った又は不用意の操作を未然に防止して、それらの問題点を解決しようとするものであり、併せて上記レバーが存在しても、ノズルキャップの外側に該ノズルキャップを保護するためのノズルカバーを装備できるようにしたものであり、更にその構造を簡潔にしようとするものである。
【０００５】

上記ノズルキャップ３の外側にノズルカバー８を被せて上記噴出器本体１の先端部に嵌合固定させ、該ノズルカバーの後部の側面側から上面側に亘って後端開口の切欠９を設けるとともに、上記ノズルキャップ３に、停止状態にて上記切欠９を介して側方へ突出するレバー６を、切欠９内を可動に装備させ、かつ該レバーにその停止態勢にて上記トリガー４の動きを阻止する係止手段７を設けたトリガー式液体噴出器のロック装置である。
【０００６】
請求項２の発明は、請求項１記載のトリガー式液体噴出器のロック装置にあって、上記噴出器本体１の前端面から支持筒 16 を前方突出して、この支持筒にノズルカバー８の後部を嵌合させるとともに、上記支持筒のうち上記カバーノズルの切欠９に相応する部分に前端開口の切欠 19 をそれぞれ形成し、これら切欠 9,19 を介してレバー６を側外方へ突出している。
【０００７】
請求項３の発明は、噴出器本体１の先端にノズル２を設け、該ノズルには回動により各種噴出態勢と停止態勢とに開路・閉路切替えするノズルキャップ３を装着し、上記噴出器本体１の前部からトリガー４を前後動可能に垂設し、また、その噴出器本体１の内部に該トリガー４で作動される往復ポンプ５を内蔵するとともに、該往復ポンプにトリガー４共々出方向に付勢する復帰ばねを備えて成り、液体を収容した容器体に装着してその液体の噴出を得るトリガー式液体噴出器において、
上記ノズルキャップ３の外側にノズルカバー８を被せて上記噴出器本体１の先端部に嵌合固定させ、該噴出器本体１の先端部の側面側から上面側に亘って前端開口の切欠 20 を設けるとともに、上記ノズルキャップ３に、停止状態にて上記切欠 20 を介して側方へ突出するレバー６を、切欠 20 内を可動に装備させ、かつ該レバーにその停止態勢にて上記トリガー４の動きを阻止する係止手段７を設けた。
【０００８】
請求項４の発明は、請求項１乃至請求項３の何れかに記載のトリガー式液体噴出器のロック装置にあって、上記レバー６につまみ片 10 を付設している。
【０００９】
【発明の実施の形態】
その1.図１乃至図３は、本発明の第１の実施の形態を示している。図示のトリガー式液体噴出器は、全ての部材乃至大半の部材を合成樹脂製とするものであり、逆Ｌ字状の噴出器本体１の先端に前方に面するノズル２を設け、該ノズルには垂直回動により噴霧、噴射等の噴出態勢（液流路開放）と停止態勢（液流路閉塞）とに切替えるノズルキャップ３を回動自在に装着し、また、噴出器本体１の前部からトリガー４を前後揺動可能に垂設し、噴出器本体１の内部に該トリガー４で作動される往復ポンプ５を内蔵するとともに、該往復ポンプにトリガー４共々出方向に付勢する復帰ばねを備え、更に、噴出器本体１の外部に本体カバー11を被着し、噴出器本体１の下端に容器体の口頸部へと取り付ける装着筒12とその容器体内へと挿入させる吸上パイプ13とを有している。また、ノズルキャップ３の外側には、噴霧による発泡を可能としたノズルカバー８を被せており、該ノズルカバーの後端を上記噴出器本体１の先端部に嵌合固定させている。勿論、該ノズルカバー８は、単にノズルキャップ３を覆うだけのものであってもよい。そして、ノズルキャップ３は、円筒状に形成して、噴出器本体１の先端に設けたノズル筒15の外周に回動により噴霧、噴射等の噴出態勢（液流路開放）と停止態勢（液流路閉塞）とが得られるよう装着しており、また、ノズルカバー８は、該ノズルキャップ３よりも大きな角筒状に形成して該ノズルキャップの外側に被せ、噴出器本体１の先端から突設した支持筒16に嵌合固定させている。ただし、該支持筒16及びノズルカバー８の一部を後記のように切欠いている。
【００１０】
上述のトリガー式液体噴出器には、ノズルキャップ３を停止態勢（液流路閉塞）にした際に、トリガー４の動きを阻止するロック装置を備えており、該ロック装置は、停止態勢のノズルキャップ３の一側後端部から側方へレバー６を突設し、該レバーにその停止態勢にてトリガー４の動きを阻止する係止手段７を設けている。
レバー６は、側面形状逆Ｌ字状に形成し、上部の基端部17すなわち前端部を内側へ直角に屈折させて停止態勢のノズルキャップ３の一側後端部へ一体に連設している。
係止手段７は、そのレバー６の先端部18すなわち下端部の内面に係止突片14を突設して、該係止突片をノズルキャップ３の停止態勢にてトリガー４の後面へ係合させることで、該トリガーの動きを阻止するようにしている。
ノズルカバー８の後部には、一側面乃至上面に浅くかつ幅の広い切欠９を設けるとともに、ノズルカバー８を嵌合させた支持筒16にも相応の切欠19を設けて、これらの切欠にレバー６の基端部17を可動に挿通させている。
【００１１】
如上の構成であるから、図１に示すように、レバー６を倒伏させたときは、ノズルキャップ３が停止態勢（液流路閉塞）となり、かつ、係止手段７たる係止突片14がトリガー４の後面に係合して、該トリガーの操作が不能となる。したがって、往復ポンプ５は全く働かない状態となり、往復ポンプ５内に液体が吸い上げられることもなければ、蓄圧貯留されることもない。
次に、レバー６を起こしたときは、ノズルキャップ３が回動して所要の噴出態勢（液流路開放）となり、係止手段７たる係止突片14がトリガー４から離脱して、該トリガーの操作が可能になる。したがって、この状態でトリガー４を引き、放しすると、往復ポンプ５が働いて、容器体内の液体が吸い上げられ、ノズル２から噴出する。
【００１２】
その2.図４は、本発明の第２の実施の形態を示している。この場合は、上述の実施の形態その1.のものにおいて、上記レバー６を側面形状Ｌ字状に形成するとともに、先端部18すなわち下端部の前面につまみ片10を付設して、レバーの操作を容易にしている。他は、上述の実施の形態その1.の場合と同様であるから、説明を省略する。
【００１３】
その3.図５、図６は、本発明の第３の実施の形態を示している。この場合は、上述の実施の形態その1.のものにおいて、ノズルカバー８の後端を前進させて前記切欠９を排し、これに相応させて、ノズルカバー８を嵌合させた支持筒16及び噴出器本体１の先端部を前方へ伸出させ、そして、その支持筒16から噴出器本体１先端部にかけて前記切欠９及び前記切欠19に代る一つの深い切欠20を設けて、該切欠20にレバー６の基端部17を可動に挿通させている。他は、上述の実施の形態その1.の場合と同様であるから、説明を省略する。
【００１４】
【発明の効果】
本願各請求項の発明によれば、既述構成であるから、次の効果を奏する。
(1)レバー６の倒伏によりノズルキャップ３を回動してノズル２を閉路させたときは、レバー６の係止手段７がトリガー４に係合して、該トリガーの作動が機械的に阻止されるから、ノズル２の閉路状態では、トリガー４が操作されることも往復ポンプ５が作動されることもなく、ポンプ内に過分に液体が吸い上げられて蓄圧貯留されることもない。したがって、この状態でノズルキャップ３を所要噴出態勢に回動させても、ノズル２が開路した途端にポンプ内の蓄圧貯留液体が不意にノズルから噴出するようなことはない。
(2)かび落し等の洗浄剤が収容された場合でも、その洗浄剤が上述のようにして不意に噴出する危険はなく、一般家庭でも安心して使用できる。
(3)ノズルキャップ３を所要噴出態勢に回動させるのを忘れたときには、トリガー４を操作することができないから、故障と勘違いすることはない。また、無理な操作が頻繁に繰り返されて、これが故障の原因となることもない。
(4)つまり、トリガー４をロックすることにより、トリガー４の誤った又は不用意の操作を未然に防止することができる。
(5)構造を簡潔にすることができ、その操作も格別のものを要せず、使用上頗る便利で、かつ、安価に提供できる。
【００１５】
請求項１、請求項３の発明によれば、レバー６が存在しても、回動するノズルキャップ３の外側に不動のノズルカバー８を支障なく装備させることができ、回動するノズルキャップ３を外力による損傷から保護することができ、また、噴出器本体１の外部に被着させるカバー11に適合した外観形象を得ることができ、見映えのよいものにすることができる。
【００１６】
請求項４の発明によれば、レバー６につまみ片10を付設しているので、該レバーの起伏操作を容易なものとすることができる。
