Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trigger type liquid ejecting container which is an improved head pressing type liquid ejecting container.

[0002]

2. Description of the Related Art Liquid ejecting containers for sucking a liquid in a container body and pressurizing the liquid to eject it from a nozzle are roughly classified into a head pressing type and a trigger type, depending on the operation. In the former head-pressing type liquid ejection container,
As described in Japanese Unexamined Patent Publication No. 137758, the head with a nozzle biased upward is moved up and down by repeating "pushing down" and "releasing". On the other hand, the latter type of trigger type liquid ejection container, as described in Japanese Utility Model Laid-Open No. 4-17855, "pulls" the trigger,
By repeating "releasing", the plunger biased in the forward direction is moved back and forth to send the liquid toward the nozzle.

[0003]

However, in the head-pressing type liquid ejection container, since the head is directly depressed by the finger, there is a problem that the burden on the finger is large and it is not suitable for ejecting a large amount of liquid. On the other hand, in the trigger type liquid ejection container, since the trigger having a lever action is pulled by the finger, it is convenient for ejecting a large amount of liquid with less burden on the finger, but the structure is more convenient than the head-pressing type liquid ejection container. It was complicated and expensive.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a trigger type liquid ejection container can be obtained by simply fitting a cylinder with a trigger into a conventional head-pressing type liquid ejection container.
