Next, the operation of this embodiment will be described.
In order to obtain the container shown in FIG. 1, the inner stopper 10 is attached to the container body 1 by stoppering, and the contents of the container body such as liquid do not jump out from the spout 16 of the inner stopper 10 at the time of stoppering, And when not in use, it is necessary to close the spout 16 of the inner plug 10 with a good sealing property.

  If the inner stopper 10 is attached to the container body 1 with a stopper, liquid in the container may jump out of the outlet 16 of the inner stopper due to vibration of the container body. Therefore, prior to plugging, the transition plug 20 is attached to the inner plug 10 as shown in FIG. At that time, in order to improve the sealing performance of the seal cylinder 24, it is necessary to make the fitting force of the seal cylinder 24 to the spout 16 sufficient.

  Next, after plugging the inner stopper 10 into the container body neck of the container with the transition stopper 20 attached, the outer cap 30 is fitted into the transition stopper 20 so as not to be relatively rotatable and unremovable by the stopper or the like. And In order to open the cap, the outer cap 30 may be rotated in one direction with the gripping cylinder 34. Then, since the fitting cylinder 31 is non-rotatably fitted to the screw cylinder 22, the screw cylinder 22 rises. Thus, the sealing cylinder 24 is detached from the spout 16 and the transition plug 20 is detached from the inner plug 10 together with the outer cap 30.

  In order to close the cap, the lower end of the female screw cylinder portion 21 of the screw tube 22 of the transition plug 20 may be engaged with the upper end of the male screw cylinder portion 13 to rotate the outer cap 30 in the other direction opposite to the above. The seal cylinder 24 is fitted into the spout 16 in a watertight manner. In addition, since the top wall 23 of the transition plug 20 is exposed, the presence or absence of the transition plug can be visually confirmed, and the quality of the sealing of the spout 16 can be determined by molding the transition plug with a transparent or semi-transparent material. It can be confirmed visually.

  FIG. 2 shows a second embodiment. In this embodiment, the outer cap 40 closes the upper surface of the fitting cylinder 31 with a top surface 41 and places the top surface 41 on the transition plug top wall 23. This point is different from the first embodiment. Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

In any of the embodiments, since the transition plug 20 and the outer cap 30 are configured as separate members, materials and colors can be made different from each other according to the purpose such as decoration.

Further, in the above, the transition plug 20 and the inner plug 10 are screwed together via the male screw cylinder portion 13 and the female screw cylinder portion 21, but the screw portion of the male screw cylinder portion 13 is the first in the circumferential direction. The first and second protrusions can be engaged with each other by changing the protrusions and the threaded portion of the female threaded cylinder portion 21 to the second protrusions in the circumferential direction. In this case, the plug is opened by raising the transition plug 20 through the outer cap 30 and forcibly getting over the first protrusion by the second protrusion.

  The present invention can be used in the field of containers that can be opened by turning the outer cap so that the transition plug is detached from the inner plug together with the outer cap.
