Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a liquid ejection container.

[0002]

[Prior Art] [Problems to be solved by the device]

 For example, as shown in Japanese Utility Model Laid-Open No. 64-25368, a container body, a cylinder vertically extending into the container and having a suction valve at the bottom, are urged upward into the cylinder and fitted into the cylinder. It consists of an operating member with a discharge valve in which a stem is erected from the cylindrical piston above the container body, and a push-down head with a nozzle is fitted on the upper end of the stem. A liquid discharge container is known which is formed so as to suck up and discharge from a nozzle.

Since the conventional example has the above-mentioned configuration, the nozzle is lowered together with the push-down head at the time of ejection, so that the liquid may be erroneously ejected to a place other than intended. Further, depending on the type of liquid, it may be necessary to repeat the ejection a plurality of times in order to obtain the required amount of liquid, but it is often uneconomical to eject more than necessary.

According to the first aspect of the present invention, an empty chamber for sucking a required amount of liquid and temporarily storing the liquid is formed inside the push-down head, and the liquid in the empty chamber is automatically sucked out and discharged from the nozzle. It is provided so that the required amount of liquid can be poured out while the tank is stationary.

[Means for Solving the Problems]

 A container body 1 that erects a mouth / neck portion 4, a cylinder 6 with a suction valve that attaches an upper end portion to the mouth / neck portion 4 and hangs down into the container body 1, and urges upward on the inner surface of the cylinder. The operating member 11 that erects the stem 12 with the discharge valve upward from the cylindrical piston that has been fitted together, and the short tubular portion 16 that hangs down from the opening peripheral edge of the central portion of the bottom wall 15 is fitted on the upper part of the stem 12. At the same time, the upper end of the peripheral wall 18 rising from the peripheral edge of the bottom wall 15 is closed by the top wall 19, and the liquid suction pipe 21 is extended from the upper portion of the peripheral wall 18 along the inner surface of the peripheral wall to the lower end of the suction pipe. And a bottom wall 15 with a liquid suction gap vertically provided between them and a spout pipe 22 communicating with the upper end of the liquid suction pipe from the upper part of the peripheral wall 18 downward to the lower end of the liquid suction pipe 21. Further, an air circulation hole 20 is bored in the peripheral wall portion above the upper end of the liquid suction pipe 21 or a part of the top wall 19 of the liquid suction pipe 21. It consists of a push-down head 14.

[0006]

[Action]

 From the state shown in FIG. 1, when the push-down head 14 screwed onto the upper portion of the cylinder 6 is unscrewed and raised with respect to the cylinder 6, and the push-down head 14 is pushed down from this state, the push-down head and The operating member 11 descends with respect to the cylinder 6, and the liquid in the cylinder is pressurized and sucked up inside the push-down head 14. When the pressing operation of the pressing head is repeated a plurality of times, the liquid gradually accumulates in the pressing head 14 and when the water level exceeds the upper end of the liquid suction pipe 21, pouring from the pouring pipe 22 starts. After this, even if the pressing head 14 is not pressed down, the liquid in the pressing head 14 is sucked up by the liquid suction pipe 21 and is gradually discharged from the pouring pipe 22 to lower the water level and suck the liquid. When air flows in from the lower end of the rising pipe 21, the pouring out is completed.

【Example】

 Reference numeral 1 denotes a container main body, which erects a mouth / neck portion 4 from an upper end of a body portion 2 through a shoulder portion 3.

Reference numeral 6 denotes a cylinder. The cylinder has an outward flange 7 attached to an upper portion thereof engaged with an upper end of the mouth / neck portion 4 and hangs down into the container main body 1 as described above, so that the outer surface of the mouth / neck portion 4 is exposed. The outward flange 7 is clamped between the upper end surface of the mouth / neck portion 4 by the inward flange 9 at the upper end of the mounting cylinder 8 that is screwed. Further, the cylinder has a suction valve in the bottom portion and has a suction pipe hanging from the lower end.

An operating member 11 is fitted in the cylinder 6 in a depressed state. The actuating member stands up the stem 12 from a cylindrical piston that is fitted in the inner surface of the lower part of the cylinder 6 in a watertight and vertically movable manner by being biased upward by a spring, and the suction valve is installed in the lower part of the stem 12. It is provided.

A transparent push-down head 14 is attached to the upper portion of the stem 12. The push-down head has a short tube portion 16 that hangs down from the opening in the center of the bottom wall 15 and is fitted to the upper outer surface of the stem 12 described above. A lower portion of the peripheral wall 18 is watertightly fitted to the inner surface of the portion 17, and an air circulation hole 20 is formed in the front portion of the top wall 19 that closes the upper surface of the peripheral wall. Further, a liquid suction pipe 21 is vertically provided from an upper portion of the peripheral wall 18 along the inner surface of the peripheral wall with a liquid suction gap provided between the lower end of the suction pipe and the bottom wall 15 so as to suck the liquid suction pipe. A spout pipe 22 communicating with the upper end of the lift pipe hangs downward from the upper portion of the peripheral wall 18 and below the lower end of the liquid suction pipe 21. The air circulation hole 20 may be formed in the peripheral wall portion above the upper end of the liquid suction pipe 21. Further, the liquid suction pipe 21 may hang down to the upper surface of the bottom wall 15, and in this case, a part of the lower end of the liquid suction pipe is cut out to open the space between the liquid suction pipe 21 and the upper surface of the bottom wall 15. It is sufficient to form a gap for sucking up the liquid. Furthermore, the volume of the vacant chamber formed in the push-down head is determined according to the required amount of liquid for one time.

A screw member 24 is attached to the upper end of the cylinder 6. The screwing member has a screw cylinder 25 fitted to the inner surface of the upper portion of the cylinder 6, and the pressing head 14 is attached by screwing the short cylinder portion 16 to the inner surface of the screw cylinder. It is attached to the cylinder 6 while being pushed down against the force.

[Effect of the device]

 The present invention is configured as described above, in which the push-down head 14 communicates with the liquid suction pipe 21 that extends from the upper portion of the peripheral wall 18 along the inner surface of the peripheral wall, and the upper end of the liquid suction pipe. 18 has a spouting pipe 22 extending from the upper part, and since the spouting pipe is hung down from the lower end of the liquid suction pipe 21, the pushing down head 14 is pushed down until a certain amount of liquid is accumulated in the pushing down head 14. If the push-down operation of 14 is performed, thereafter, the liquid in the push-down head 14 is gradually poured out from the pouring pipe 22 through the liquid suction pipe 21 without pushing down the pushing head 14. The pouring pipe 22 can be kept stationary during pouring, so there is no risk of accidentally ejecting liquid to an unintended location, and it is convenient because both hands can be used freely during pouring. In addition, since a certain amount of liquid accumulated in the push-down head 14 is poured out, only the required amount can be used without waste. It is economical.
