[0022]

As described above, the present invention has the above-mentioned structure.
As an effect of the above case, the lower part of the outer cylinder 22 of the double cylinder part is directed toward the inside of the mounting cylinder regardless of the method of fixing the screwing member double cylinder part to the mounting cylinder 8 without changing the same as before. Since it is dropped between the inner peripheral surface of the flange 2 and the mounting cylinder 26 which stands up from the outward flange of the cylinder, the height from the lower surface of the outward flange 5 to the upper surface of the double cylinder portion of the screw member 20 is adjusted. The thickness of the inward flange 2 can be reduced by the thickness of the mounting cylinder 1, and the height from the upper surface of the mounting cylinder 1 to the upper surface of the push-down head 13 can be made as short as possible. The height from the lower end to the upper surface of the push-down head 13 can be lowered, and therefore the overall height with the ejector attached to the container can be made lower than the conventional product, so that the packaging can be made smaller and the material etc. It is possible to reduce various expenses. Further, if the overall height is the same as that of the conventional product, especially the outward flange 5 from the lower end of the mounting cylinder 1 to the upper surface of the pressing head.
The height of the container can be increased by the amount of the decrease in the height from the lower surface to the upper surface of the pressing head. Therefore, it is convenient to make a container with a larger capacity than before without changing the external size. is there.

In the case of claim 2, in addition to the above effect, the screwing member 20 never rotates with respect to the mounting cylinder 1, and in the conventional case, the screwing tightening of the operating member 14 to the female screw cylinder 21 is too strong. For example, when the consumer tries to unscrew the operating member to take out the stored liquid, the screwing member 20 and the cylinder 3
There was a case in which the screw was idled with respect to the container body and the mounting cylinder 1 and the unscrewing thereof was troublesome. However, since the screwing member 20 and the mounting cylinder 1 were integrally molded, the operating member was unscrewed by holding the mounting cylinder. This does not cause any trouble as described above.

According to the third aspect, in addition to the effect of the first aspect, the second outward flange in which the screwing member 20 and the actuating member 14 are screwed together at the upper end of the screwing member double cylinder portion. 26 Since the outer peripheral surface and the inner surface of the peripheral wall 16 hanging down from the outer peripheral surface of the top wall of the operating member pressing head are used, it is not necessary to provide a female screw on the inner surface of the inner cylinder 21a of the double cylinder portion, and in the case of the conventional product having the female screw. When a container equipped with a liquid ejector is used in a bath or the like, scattered water or hot water may enter the container body through the female screw groove, which may cause the liquid in the container to become cloudy. Then, such clouding can be prevented. Further above second
Since the outward flange 26 is extended above the inner peripheral portion of the inward flange 2, the inward flange 2 is provided between the second outward flange 26 and the first outward flange 5 of the cylinder 3.
Since the inner peripheral portion is located, the mounting cylinder 1 does not come off even when the operating member 14 is unscrewed.

Further, in the case of the invention of claim 4, the above-mentioned claim 3 is adopted.
The mounting cylinder 1 and the screwing member 20 of FIG. 2 are erected from the inner circumference of the inward flange 2 to a short cylinder 29, and the upper end of the short cylinder is connected to the second outward flange.
26 Since they are connected to the lower surface and they are integrally molded with a synthetic resin material, the effects of the inventions of claim 3 and claim 2 can be obtained.
