【０００５】
請求項２の発明は、容器体１の口頸部11に、押下げ噴出ヘッド22を備えた縦型往復ポンプ21から成る噴出器本体２を装着し、上記押下げ噴出ヘッド22の周りに、上記容器体１の肩部へ下端嵌合部33を嵌合固定させて該下端嵌合部から左右一対の側壁31と後壁32とを起立連設した外装カバー３を配備させ、該外装カバーの両側壁31内上部に、前部42を前方へ突出させた側面形状ヘ字状のトリガー４を後部41にて上記押下げ噴出ヘッド22に被せて配するとともに、該トリガー４の後端を上記側壁31の後部にその押下げ噴出ヘッド22の押し下げ回動可能に枢着５し、かつ、該トリガー４の前部42の上位点に、上記押下げ噴出ヘッド22に対応させて噴出窓43を穿設し、更に、そのトリガー４の前部42の中間点に、上記外装カバー３の前面へ隣接させて横孔47を穿設し、該横孔にロックピン６を抜き差し自在に挿入して該ロックピンを上記外装カバー３の前面へ当接させ、また、上記トリガー４の後部41の適所に、引き抜きした上記ロックピン６を保持させるロックピン支持手段７を設け、該ロックピン支持手段として、上記トリガー４の後部41の上面適所に、上記ロックピン６を着脱自在に挿入支持させる支持孔71を穿設したことを特徴とする。
【０００６】
而して、請求項３の発明は、容器体１の口頸部11に、押下げ噴出ヘッド22を備えた縦型往復ポンプ21から成る噴出器本体２を装着し、上記押下げ噴出ヘッド22の周りに、上記容器体１の肩部へ下端嵌合部33を嵌合固定させて該下端嵌合部から左右一対の側壁31と後壁32とを起立連設した外装カバー３を配備させ、該外装カバーの両側壁31内上部に、前部42を前方へ突出させた側面形状ヘ字状のトリガー４を後部41にて上記押下げ噴出ヘッド22に被せて配するとともに、該トリガー４の後端を上記側壁31の後部にその押下げ噴出ヘッド22の押し下げ回動可能に枢着５し、かつ、該トリガー４の前部42の上位点に、上記押下げ噴出ヘッド22に対応させて噴出窓43を穿設し、更に、そのトリガー４の前部42の中間点に、上記外装カバー３の前面へ隣接させて横孔47を穿設し、該横孔にロックピン６を抜き差し自在に挿入して該ロックピンを上記外装カバー３の前面へ当接させ、また、上記外装カバー３の後部に、引き抜きした上記ロックピン６を保持させるロックピン支持手段７を設け、該ロックピン支持手段７として、上記外装カバー３の後部適所に、上記ロックピン６を着脱自在に嵌挿係止させる耳孔状切欠72を形成したことを特徴とする。

請求項１乃至請求項３の発明によれば、押下げ噴出ヘッド作動用トリガー４を可動に装着し、該トリガーの適所に該トリガーの作動を阻止するロックピン６を抜き差し自在に装備させているので、ロックピン６を差し込みすることにより、トリガー４の回動を阻止できて、噴出器本体２の作動を阻止でき、したがって、容器体１に所要の液体が充填された状態で商品流通過程を転々流通しても、その運送、積み替え等において、トリガー４に不意の外力が加わって内容物が流出することも、店頭での陳列等において、トリガー４が不当に操作されて内容物が所定量以下に少なくなるようなこともなく、商品価値を低下させるようなことはない。
また、トリガー４を操作するときは、そのロックピン６を引き抜けばよいから、ロックピン６の操作、取り扱いが容易に行える。
【００１８】
加えて、請求項１乃至請求項３の発明によれば、トリガー４の前部42の中間点に、上記外装カバー３の前面へ隣接させて横孔47を穿設し、該横孔にロックピン６を抜き差し自在に挿入して該ロックピンを上記外装カバー３の前面へ当接させているので、横孔47にロックピン６を挿入することでロックピン６によりトリガー４の動きを的確に阻止することができ、かつ、その阻止状態を支障なく維持することができる。
そして、ロックピン６を引き抜いたときは、そのロックピン６をロックピン支持手段７に保持させることができ、次回の使用に便利である。
また、外装カバー３とトリガー４が噴出器本体２を覆うので、該噴出器本体の押下げ噴出ヘッド22及び縦型往復ポンプ21を外力から保護でき、塵埃の侵入等を少なくすることができる。
【００１９】
更に、請求項２の発明によれば、ロックピン支持手段７として、トリガー４の後部41の上面適所に、上記ロックピン６を着脱自在に挿入支持させる支持孔71を穿設しているので、引き抜きした無用時のロックピン６を挿入させて的確に支持でき、また、請求項４の発明によれば、ロックピン支持手段７として、外装カバー３の後部適所に、耳孔状切欠72を形成しているので、引き抜きした無用時のロックピン６を嵌挿させて的確に係止保持でき、しかも、これらのロックピン支持手段７は、構造が簡潔で、コンパクトなものにでき、製作が容易で、安価に提供できる。

【The invention's effect】
According to the first to third aspects of the present invention, the trigger 4 for operating the push-down ejection head is movably mounted, and the lock pin 6 for preventing the operation of the trigger is provided at an appropriate position of the trigger so as to be freely inserted and removed. Therefore, by inserting the lock pin 6, the rotation of the trigger 4 can be prevented, and the operation of the ejector main body 2 can be prevented. Therefore, the product distribution process is performed in a state where the required liquid is filled in the container body 1. Even if it is circulated from one place to another, during transportation, transshipment, or the like, unexpected external force may be applied to the trigger 4 to cause the contents to flow out. There is no such thing as below, and there is no decrease in commercial value.
When the trigger 4 is operated, the lock pin 6 may be pulled out, so that the operation and handling of the lock pin 6 can be easily performed.
[0018]
In addition, according to the first to third aspects of the present invention, a horizontal hole 47 is formed at an intermediate point of the front portion 42 of the trigger 4 so as to be adjacent to the front surface of the exterior cover 3 and locked in the horizontal hole. Since the pin 6 is freely inserted and removed and the lock pin is in contact with the front surface of the outer cover 3, the lock pin 6 is inserted into the lateral hole 47 so that the movement of the trigger 4 is accurately performed by the lock pin 6. It can be blocked, and the blocking state can be maintained without hindrance.
When the lock pin 6 is pulled out, the lock pin 6 can be held by the lock pin supporting means 7, which is convenient for the next use.
Further, since the exterior cover 3 and the trigger 4 cover the ejector main body 2, the push-down ejection head 22 of the ejector main body and the vertical reciprocating pump 21 can be protected from external force, and the intrusion of dust and the like can be reduced.
[0019]
Furthermore, according to the second aspect of the present invention, since the lock pin supporting means 7 is provided with a support hole 71 for removably inserting and supporting the lock pin 6 at an appropriate position on the upper surface of the rear portion 41 of the trigger 4, According to the fourth aspect of the present invention, an ear-hole-shaped notch 72 is formed at an appropriate position at the rear of the outer cover 3 as the lock pin supporting means 7. As a result, the lock pin 6 that has been pulled out can be properly engaged and retained by being inserted, and the lock pin support means 7 can have a simple structure, be compact, and be easily manufactured. , Can be provided at low cost.
