Description of the Related Art In general, a liquid ejector of a trigger type erects a vertical cylinder from the upper part of a mounting cylinder to be fitted to a mouth and neck of a container body, an injection cylinder from an upper end of the vertical cylinder, and a cylinder from an intermediate part. The plunger front end, which is protruded forward into the cylinder and is fitted to the upper rear portion of the trigger, which protrudes forward and is vertically suspended from the front portion of the injection cylinder so as to be swingable in the front-rear direction, is locked. It is provided so that the liquid in the container is sucked into the cylinder by a moving operation and the liquid in the cylinder is ejected from the nozzle at the front end of the injection cylinder.

る。When the trigger 32 is pulled from the state shown in FIG.
The liquid that has entered the vertical cylinder 35 through 45 enters the injection cylinder 26 by elastically deforming the discharge valve body 40, and is ejected from the nozzle hole 30. When the trigger 32 is released, the spring 32, 5 restores the trigger 32 and the plunger 33 to their original positions. At this time, the high-pressure state is eliminated, and the elastic discharge valve body 40 moves the outer peripheral portion of the upper end to the inner surface of the vertical cylinder 35. Since the discharge valve is closed by pressing against the pressure, the inside of the cylinder 27 becomes negative pressure, and the suction valve body 38 closing the suction valve hole due to the negative pressure resists the elasticity of the intermediate spring plate. When pushed up, the liquid in the container enters the cylinder 27 through the suction pipe 46 to prepare for the next ejection of the liquid by the trigger pulling operation.

The opening 2 is applied to the outer surface of the vertical cylinder 35 of the trigger type liquid ejector, and the half-cylindrical holding plate 3 is elastically deformed and fitted to the outer surface of the vertical cylinder 35 simply by pressing the half-cylindrical holding plate on the outer surface of the vertical cylinder 35 of the trigger type liquid ejector. The spring plates 5, 5 which are bent up and down from the semi-cylindrical holding plate 3 project forward substantially in parallel from the plane, with an appropriate gap therebetween, so that they are injected into the gap between the spring plates 5, 5. The front end of the spring plate can be locked into the concave portion 43 provided on the upper rear surface of the trigger 32 by loosely inserting the cylinder 26. Thus, regardless of whether the spring member 1 is formed of a synthetic resin material, the spring plate 5,5
The plunger 33 can be biased forward through the trigger 32 by increasing the length and elasticity of the plunger.

In addition to having the effect of the spring member described above, spring plate bases 5a, 5a are erected from the left and right sides of the front wall portion of the semi-cylindrical holding plate 3 via front protruding rods 4, 4. The spring plate middle portions 5b, 5b extending from both base portions are extended to the large curved portions 6, 6 extending upward and forward, and the upper surface is slightly curved from the large curved portion tip to form the spring plate tip portions 5c, 5c. Because of the protrusion, the spring plates 5, 5 are elastically deformed almost uniformly as a whole by the pulling of the trigger, and the elasticity capable of urging the plunger 33 forward through the trigger 32 is easily obtained. Further, since the front ends of the spring plates are connected by the spacing plate 7 and the engaging plate 8 for trigger engagement protrudes from the front surface of the spacing plate, the spring plates 5 and 5 are always elastically deformed at the same time. The elasticity can be increased and the spring member 1 can be easily mounted on the trigger type liquid ejector.
