A vertical cylinder is erected from the upper part of the mounting cylinder to be fitted to the outer surface of the neck of the container body, and the injection cylinder is projected forward from the upper end of the vertical cylinder, and the trigger is suspended by pivotally attaching to the front of the injection cylinder,
Further, the plunger is biased forward and fitted into the cylinder protruding forward from the vertical cylinder, the plunger front end is engaged with the upper rear surface of the trigger, and the trigger pulls the liquid in the cylinder through the discharge valve. The trigger is provided so that the liquid in the container is sucked into the cylinder via the suction valve when the plunger moves forward and the inside of the cylinder becomes negative pressure by releasing the trigger. Liquid ejectors of the type are well known. As shown in Japanese Utility Model Application Laid-Open No. 6-34759, this type of trigger type ejector generally has a cover that covers the left and right sides of the ejector body in order to improve the appearance.

目的とする。The cost is also a problem in the trigger type ejector as in other products. However, in the case of this type of product, when the number of molding dies and the labor for assembling are taken into consideration, the cost reduction requires the number of members. Reduction is most effective. However, in the conventional trigger type ejector described above, the suction valve and the discharge valve are formed as separate members, and the cover is formed as an independent member separately from the other members, so there is room for improvement in reducing the number of members. . Conventionally, the cylinders that need to be covered with a cover are protruded forward from the middle of the vertical cylinder, so that the cover needs to extend at least below the middle of the vertical cylinder, and there has been a limit to miniaturization of the cover. . Further, in the related art, since the spring material for urging the trigger forward is housed inside the cylinder, the substantial volume of the cylinder is reduced by the spring material, and the cylinder becomes large and inefficient in order to secure a predetermined substantial volume. Had become. Further, conventionally, a metal material was used as the spring material, and a synthetic resin material was used as the other members. Further, as described above, most of the conventional ejectors have the cylinder projecting forward from the vertical cylinder and the trigger is drooping from the injection cylinder, and most of them are similar in appearance to each other. The product could not be differentiated. The present invention has been made in view of the above problems, and an object of the present invention is to provide a trigger type ejector capable of reducing the number of members, reducing the size of a cover and a cylinder, and differentiating products.

する。E is a spring member. The spring member E has its rear end integrally connected to the rear end of the support plate 25 via a thin hinge 38, and has its rear end 39 supported by the rear end of the support plate 25. From the end portion 39, a set of bar springs 40 curved upward is projected forward, and the front ends of the bar springs 40 are joined to each other by a cross member 41,
The cross member 41 is pressed against the top wall of the horizontal portion 29. A pair of bar springs 40 is elastically deformable downward with the rear end 39 as a fulcrum, and the interval in the left-right direction is larger than the diameter of the outer cylinder 15. And the outer cylinder 15 do not interfere with each other. In the above description, the case where the spring member E is integrally connected to the support plate 25 by integral molding has been described. However, the present invention is not limited to this, and both may be formed separately and connected. From the viewpoint of cost reduction by reducing the number of members, it is preferable to integrally mold them. However, there is a case where the integral molding may increase the cost, and in this case, both are appropriately molded separately. .

る。The operation of this embodiment will be described below. In use, when the hanging portion 31 of the trigger D is pulled, a counterclockwise rotating force acts on the horizontal portion 29, so that the spring member E elastically deforms downward with the rear end portion 39 as a fulcrum,
At the same time, the horizontal portion 29 rotates counterclockwise about the pin 30 to push down the plunger F downward. Then
Since the liquid in the inner cylinder 16 is pressurized and the skirt-shaped wall 12 is separated from the inner peripheral surface of the inner cylinder 16, the liquid is discharged from the discharge hole 18 to the discharge path 20, further passes through the injection cylinder 21, and from the nozzle hole 23. Gushing.

内に導入される。When the trigger D is released after the ejection, the horizontal portion 29 of the trigger D rotates clockwise due to the elastic deformation resistance of the spring member E, and at the same time, the plunger F starts to be displaced upward and the inner cylinder 16 moves. The inside becomes negative pressure. Then, the valve plate 13 is separated from the valve hole 7 against the urging force of the spiral spring piece 14, and the skirt-shaped wall 12 is pressed against the inner peripheral surface of the inner cylinder 16, so that the liquid in the container is discharged from the inner cylinder 16. Is sucked. On the other hand, since the communication valve hole 17 is open until the plunger F reaches the upper limit or near the upper limit, air from outside the inner cylinder 16 flows between the inner and outer cylinders 16 and 15 through the communication valve hole 17, Further, it is introduced into the container through the introduction valve hole 9.

異なり、したがって商品の差別化が可能になる。According to the first and second aspects of the present invention, since the cylindrical valve member is provided with the valve plate and the skirt-like wall so that it functions as both the suction valve and the discharge valve, the number of members can be reduced. Becomes possible. In addition, since the horizontal portion of the trigger is located above the inner and outer cylinders, the trigger can also serve as a cover, so that the number of members can be reduced and the structure can be simplified. Further, since the plunger protrudes upward from the inside of the inner cylinder, the length of the cover in the vertical direction can be shortened to cover the plunger, so that the size of the trigger that also serves as the cover can be reduced. Furthermore, since the spring member is provided outside the inner cylinder that also serves as the cylinder, the substantial volume of the inner cylinder is not reduced by the spring member, and thus not only can the inner cylinder be downsized, The structure of the inner cylinder can be simplified. Further, since the cylinder is also used as the inner cylinder without protruding forward as in the conventional case, and the trigger horizontal portion is disposed above the inner and outer cylinders, the appearance is significantly different from that of the conventional ejector, and therefore the product is Can be differentiated.
