ことを防止することにある。[Prior Art] As shown in FIG. 2, a container body 1 with a mouth and neck portion 2 erected, a mouth top surface of the container body, and an outward flange 5 attached to the upper part are placed on the container body. A cylinder 3 has a vertically cylindrical portion, an outside air suction hole 26 is formed in the cylindrical wall immediately below the outward flange, and a suction valve 7 is provided in the lower end of the cylinder, and a cylindrical portion is provided on the outer surface of the mouth and neck. A cap-shaped member 10 in which the outward flange 5 is held between the inward flange 12 attached to the upper end of the cylindrical portion and the top surface of the mouth of the container, and the inner surface of the upper end of the cylinder. A screw cylinder 13 having a cylinder part 14 fitted in an unrotatable manner and having a thread on the inner surface of the cylinder part, and a lower outer surface of a cylinder part 17 hanging down from the top wall 16 are screwed into the thread. A push-down head 15 with a nozzle 16a protruding from the upper part of the cylinder, and a pipe part 18 hanging down into the cylinder 3 by fitting the upper end into the cylinder part, and a discharge valve 19 into the upper end of the pipe part. , and stems 21 each having a cylindrical piston 20 attached to the lower end of the tube, and by screwing off the cylindrical portion of the push-down head from the screw cylinder, the push-down head is moved up and down with respect to the cylinder. A liquid ejection container is known in which the liquid inside the container is sucked into a cylinder and ejected through a stem, a discharge valve, and a nozzle. The reason why the cylindrical part of the push-down head is screwed into the above-mentioned screw cylinder and the stem is pushed down into the cylinder is to prevent the push-down head from being inadvertently pushed down and the liquid to be spouted out, and also to prevent liquid from being spewed out during transportation. The purpose is to prevent the container from becoming bulky.

た。[Problems to be solved by the invention] When using the above-mentioned liquid ejection container, the push-down head cylindrical portion is unscrewed from the screw cylinder, and the stem and push-down head can be moved up and down with respect to the cylinder. However, during transportation etc. in the screwed state, liquid enters between the cylinder 3, the stem 21, and the cylindrical piston 20 at the lower end of the stem, and the liquid is pushed down by the unscrewing. When the head 15 and stem 21 were raised, liquid sometimes leaked between the screw tube 13 and the stem 21.
In addition, when the stem is raised, a gap is created between the screw cylinder and the stem, so the stem and push-down head tend to wobble, and if the gap is made smaller to reduce this wobbling, the negative pressure inside the container due to the decrease in liquid increases. The gap and outside air intake hole 2 to prevent
There was a drawback that the intake of outside air through 6 was incomplete.

本案は上記欠点を除去することを目的とするも
のである。 The present invention aims to eliminate the above-mentioned drawbacks.

とが出来る。[Operation] From the state shown in FIG. 1, when the push-down head 15 is turned in the forward direction with respect to the cap-shaped member 10 or the screw tube 13, the squeeze valve 27, which cannot be lifted up with its upper surface in contact with the lower end surface of the tube portion 14, is opened. Leave the screw tube 13 in position.
When the cylindrical portion 17 is unscrewed from the cylinder 3, the stem 21 is pushed down by the elastic force of the spring 24 attached to the inner bottom of the cylinder 3. The liquid that has accumulated between the lower part of the stem, the cylindrical piston 20, and the inner surface of the cylinder tries to escape upward and outward while remaining attached to the stem, but the squeeze valve 27 is forcefully slidably fitted to the stem. At this time, due to the frictional engagement with the stem, the upper surface of the squeeze valve closes the gap between the stem and the screw cylinder in a watertight manner, so that it is returned into the container body through the outside air intake hole 26. When the push-down head 15 is pressed down, the squeeze valve 27 also initially moves down together with the stem 21, but when the outer edge of the outward flange 30 of the squeeze valve 27 engages with the upper surface of the upward step 25, the squeeze valve stops and the squeeze valve 27 is moved downward. Only the stem 21 is lowered, leaving the stem 21 on the upper inner surface of the cylinder. Since the outward flange is provided with a groove 29, an amount of outside air corresponding to the amount of liquid to be ejected enters the container body between the stem and the barrel and through the groove, thereby causing negative pressure inside the container body. is prevented. The squeeze valve 27 moves up and down together with the stem 21 due to frictional engagement with the outer surface of the stem 21 only between the lower end surface of the cylindrical portion 14 and the upward step portion 25. Furthermore, the outward flange 3 of the squeeze valve
By reducing the gap between the outer surface of the cylinder and the inner surface of the cylinder, it is possible to prevent the stem from shaking relative to the cylinder.

容易かつ迅速に行うことが出来る。[Effect of the invention] Since the present invention has a structure having the above-described function, when the cylindrical portion of the push-down head is screwed off from the screw tube 13 and the stem etc. rises, liquid leaks from between the stem and the screw tube. Also, since the outer surface of the outward flange of the squeeze valve fitted to the stem can be brought close to the inner surface of the upper part of the cylinder, it is possible to reduce the grating of the stem against the cylinder, and further reduce the gap between the stem and the screw tube. Since the attachment of the stem will not become large even if the gap is increased, by increasing the gap, it is possible to enlarge the outside air intake passage necessary to prevent negative pressure inside the container. Even if the push-down head is moved up and down to eject the liquid inside the container in a short time, the inside of the container does not become under negative pressure, and the liquid can be ejected easily and quickly.
