Description of the Related Art A cylinder having a suction valve on the inner surface of the bottom is hung in a container body, and an actuating member is erected by urging upward from the inside of the cylinder, and a head with a nozzle fitted to the upper end of the actuating member is moved up and down. A liquid ejection container is widely used in which the liquid in the container is moved into the cylinder by moving the liquid and the liquid in the cylinder is ejected from the nozzle.

号) が開発された。Since the liquid ejector is provided so as to eject the liquid immediately by the high pressure in the cylinder, when the liquid is ejected or when the liquid ejection is stopped, the liquid may be dripped due to insufficient liquid ejection pressure. When the internal pressure reaches a reference distance where the flight distance is appropriate to eliminate the defect, the discharge valve, which was blocked by the bias, opens, and when the liquid in the cylinder drops below the reference internal pressure, the discharge valve closes immediately. Accumulation type liquid ejecting container (Sho 54-39693

If the slider tube is fitted by urging the cylinders upward between them and the operating member is pushed down from the state where liquid flows into both cylinders and the slider tube, the pressure difference will cause a difference in diameter between the cylinders. When the slider tube descends against the bias, the discharge valve element provided on the slider tube also descends to open the discharge valve, and liquid is ejected through the discharge valve. When the liquid pressure in the cylinder and the slider tube is lowered, the slider tube is automatically raised to close the discharge valve.

る。The suction valve may be formed of a ball valve or the like, but in the illustrated example, the valve rod 47 is hung from the center of the bottom plate of the small diameter cylinder 42, and the valve rod is pierced at the center of the cylinder bottom wall. The suction valve hole 25 is provided so as to be inserted into the elastic tapered cylinder 25a which is erected upward from the outer periphery of the suction valve hole 25. In this case, as shown in FIG. 1, when the operating member 31 is located at the upper limit, the valve rod 47 is pulled out from the upper end of the tapered barrel 25a, and when the operating member 31 is pushed down a little, the lower portion of the valve rod is tapered barrel 25a. It is provided so that the suction valve 48 is closed by entering the upper part of the. However, as described above, it is not always necessary that the lower end of the valve rod 47 be provided so as to come out from the upper end of the tapered cylinder 25a. This will be described later.

よう設けている。By vertically or circumferentially forming a groove 49 on the upper end of the valve rod 47, when the upper end of the tapered cylinder 25a is located on the outer surface of the groove, the inside of the cylinder 21 and the inside of the suction pipe 27 communicate with each other. It is provided to do so.

するノズル38内を通って噴出する。In the above structure, when the actuating member 31 is moved up and down several times in advance and the actuating member 31 is pushed down as shown in FIG. 2 from the state of FIG. After entering the inside of 25a and closing the suction valve 48, the inside of the cylinder 21 is made to have a high pressure by further pressing it down, so that the inside of the flow path 46 is also made to have a high pressure. Due to the high pressure, the discharge valve body 44 is pushed down into the small diameter cylinder 42 against the bias,
As the discharge valve body descends, the discharge valve hole 36 opens, so that the high-pressure liquid in the cylinder passes through the liquid outflow cylinder 37 and is further ejected through the nozzle 38 of the head 39.

閉塞する。The discharge valve element 44 rises due to the release of the high pressure in the cylinder such as the stop of the pressing of the operating member 31 and the discharge valve hole 36.
However, when a groove 49 is provided in the upper portion of the valve rod 47 as shown in the drawing, when the upper end of the tapered cylinder 25a is located on the outer surface of the groove, the high pressure liquid in the cylinder passes through the groove 49. In order to eliminate the high pressure state in the cylinder by escaping into the suction pipe 27, the discharge valve element 44 rises at the same time as the discharge and the discharge valve hole 36 is closed.

位置するよう設けてもよい。Next, when the head 39 is released, the operating member 31 rises, and when the valve rod 47 pulls out the tapered cylinder 25a, the inside of the cylinder 21 is negatively pressured by the rise of the top cylinder 35.
The negative pressure state is eliminated by sucking the liquid in the container through the suction pipe 27. Note that the tapered cylinder 25a is easily elastically deformed, that is, by making it thin and long, the tapered cylinder 25a elastically expands while the valve rod 47 rises from between the tapered cylinders 25a. It is also possible to flow the liquid into the cylinder, and in this case, the lower portion of the valve rod 47 may be provided in the tapered cylinder 25a with the actuating member 31 positioned at the upper limit.

る。As described above, the actuating member upper urging spring 41 is fitted between the top wall portion inside the guide cylinder 14 and the lower surface of the head 39 outside the peripheral wall 33, and also into the small diameter cylinder 42. By providing the spring 45 for urging the discharge valve body upward, it is possible to prevent both springs from getting wet with the content liquid and rusting.

来る。The present invention has the above-described structure. By forming the present invention as set forth in claim 1, the discharge valve body 44, which constantly closes the discharge valve hole 36 by upward bias, has a constant cylinder inside. When it reaches the high pressure state, the discharge valve is automatically pushed down to open the discharge valve, and the liquid pressure in the cylinder becomes lower than the biasing force above the discharge valve body and the discharge valve is closed at the same time. Therefore, as a pressure-accumulation type liquid ejection container, it is possible to improve liquid drainage during liquid ejection and when ejection is stopped.

Since the discharge valve hole 36 formed in the top plate is closed, the entire pump does not become large as in the case of using the slider tube in the above-mentioned conventional example.
