の際、各弾性突片26は各係止突起９を乗り越え、外方へ
湾曲した弾性変形状態でその側面に係合されている。The case of using the liquid ejecting apparatus 1 configured as described above will be described. First, when the ejection head 6 is pushed down against the elastic force of the coil spring 31 from the state of FIG. 11 (a), the push-rotating mechanism A acts to horizontally rotate the transmission cylinder 5. At this time, due to the action of the rotation pressing mechanism B, the piston member 4 descends as shown in 11 (b). That is, the spout cylinder 18 having the screw thread 20 which is screwed into the rotating screw projection 24 is about to be screwed down, but it is moved straight down due to the engagement between the vertical projection 21 and the vertical projection 15. Then, the stored liquid below the piston 17 is pressurized, the slit valve 23 is opened, and the liquid is discharged. Further, at this time, each elastic projection piece 26 rides over each locking projection 9 and is engaged with the side surface thereof in an elastically deformed state which is curved outward.

再び吐出ヘッド６を押し下げれば同様の作用を繰り返
す。Next, when the pressure on the ejection head 6 is released, as shown in 11 (c), the ejection head 6 is urged by the upward biasing force.
Is pushed up, the push-down rotation mechanism A is disengaged, and the adjusting rotation mechanism C causes the transmission cylinder 5 to slightly rotate in a predetermined rotation direction, so that the cam-shaped projections of the push-down rotation mechanism A are rotated. 25 and 36 are rotated to a position where they can be engaged, that is, to a starting position of the push-down rotating mechanism A.
If the ejection head 6 is pushed down again, the same operation is repeated.

【発明の効果】以上説明した如く、本発明の液体吐出器
は、既述構成としたことにより、吐出ヘッド６を押し下
げるという簡単な操作により略定量の液を吐出すること
ができる。As described above, the liquid ejector according to the present invention, which has the above-described structure, can eject a substantially fixed amount of liquid by a simple operation of pushing down the ejection head 6.

るものである。Further, since the pushing-down force of the discharge head 6 is converted into the rotational force of the transmission cylinder 5 and then converted into the descending force of the piston member 4, there is a buffering action and the piston member 4 suddenly moves.
The pushing down of the discharge head 6 is prevented as much as possible, and since the pushing down of the discharge head 6 has some play, the pushing down of the piston member is not direct, and as a result, sudden ejection of the discharge liquid can be prevented.
【００３１】また、シリンダ等を使用せずに容器体に直
接ピストンを摺動させ、弁も必ずしも使用しなくて済む
ため、従来のポンプと比較して構造が簡単であり、試供
品として充分活用できるものである。Further, since the piston can be slid directly on the container body without using a cylinder or the like and the valve does not necessarily have to be used, the structure is simple as compared with the conventional pump, and it is sufficiently used as a sample product. It is possible.
