公昭６１−９２０号公報）。2. Description of the Related Art A oscillating trigger (trigger) causes a piston in a cylinder of a pump to reciprocate, sucks a liquid in a liquid container (hereinafter abbreviated as a container) from a hanging suction tube, and ejects the liquid from a nozzle. A liquid ejector (hereinafter, abbreviated as an ejector) for causing the injection is known (for example, Japanese Utility Model Publication No. 61-920).

It is also known that the device is attached to the container by rotatably externally inserting it into the leg portion as a retaining member and sandwiching the flange between the ceiling surface of the screw cap and the upper surface of the opening neck portion of the container. (For example, the above-mentioned gazette).

非常に長い吸い込みチューブを有することとなる。By the way, in this type of ejector, since the piston is driven by the swinging trigger,
Since the cylinders constituting the pump are arranged horizontally or inclined in the front-back direction of the ejector body, for example, as in a vertical pump-type ejector (for example, Japanese Utility Model Publication No. 63-2120), from below the ejector body. No part of the cylinder protrudes into the container, resulting in a very long suction tube in this type of ejector.

る。On the other hand, in order to suck up the last drop of the liquid in the container without waste, it is well known that the end of the suction tube is positioned so as to reach the bottom corner of the container. That is, in this case, if the container is used while being tilted so that the liquid collects in the corner where the end of the suction tube is located, the liquid can be sucked up to the last drop.

いた。Therefore, in the prior art, the total length of the suction tube is set to be longer than the internal height of the container, and when the ejector is mounted on the container, the suction tube is bent in a desired direction and its end is a corner of the bottom. Had been induced to reach.

った。However, in the above-mentioned prior art, when the ejector is manually attached to the container,
Since the direction of the suction tube can be adjusted with your fingertips, there is no problem, but when using an automatic mounting machine, the total length of the suction tube in this type of ejector is very long and the rigidity is weak, so it sucks in an unexpected direction. It was easy for the tube to bend and the end did not reach the bottom corner well.

制している。Reference numeral 40 in the drawing is a packing member which constitutes a characteristic part of the present invention. The packing member 40 is made of a highly elastic material, and is fitted into the inner cylinder 4 above a disk-shaped main body having an outer diameter matching the flange 3 formed at the lower end of the inner cylinder 4. Power cylinder 41
And the hole 42 through which the suction tube 10 should pass is provided below. In this case, the suction tube 10 is connected to the pump P by having one end fitted and fixed below the pipe 44. The position of the hole 42 provided in the main body of the packing member 40 is displaced with respect to the fixed portion 10B of the suction tube 10 so that the suction tube 10 penetrating therethrough is inclined and the end thereof is a liquid container. Reach the bottom corner of the. Further, in this embodiment, the guide projection 43 is vertically provided from the peripheral side of the hole 42 to regulate the inclination angle of the suction tube 10 in contact therewith.

Is a communication hole with the outside air for eliminating the negative pressure state in the liquid container C caused by the suction of, and is formed in the cylinder 12, the inner cylinder 4, and the packing member 40, respectively. In this embodiment, the hole 42 through which the suction tube 10 penetrates is made larger than the outer diameter of the suction tube so that the suction tube 10 also serves as the communication hole of the packing member 40. Then, by arranging the communication hole 32 of the cylinder 12 in the above in a position where it is closed by the piston 13 when the trigger 11 is returned (state of FIG. 4) and communicates with the outside air when the trigger 11 is pulled. The negative pressure state in the liquid container C is released when the trigger 11 is pulled.

更が最小限で済む。As a means for inclining the suction tube, a packing member for ensuring watertightness between the ejector and the container is used, so that there is no waste in the structure and the present invention can be achieved without substantially changing the structure of the existing ejector. Since it can be carried out, the change of the mold can be minimized.

よいので、製造効率が極めて高い。The inclination degree of the suction tube for the end of the suction tube to reach the corner of the bottom of the container varies depending on the shape of the container to which the ejector is to be attached. Since the body of the container is left as it is and only the packing member is prepared according to various inclinations, the manufacturing efficiency is extremely high.
