Thus, the upper surface 55 of the collar portion 24 and the upper surface 57 of the stepped outer peripheral portion 56 of the dish-shaped shoulder portion 8 are configured to be on the same plane. As a result, the flow of liquid flowing out from the outflow port 30 toward the beak 14 during liquid injection becomes smooth, and a pool of liquid occurs around the liquid supply/drainage port 3 of the dish-shaped shoulder 8 after liquid injection. can be prevented. In this embodiment, the flow regulating ribs 29 are provided only at the outlet portion 30.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, in the above embodiment, a screw-type plug is used as the plug 4, but
Alternatively, a swingable stopper hinged to one end of the container body 2 may be employed.

According to the present invention, the flow of liquid flowing out of the plug body, which is easily disturbed by the communication passage, which tends to be complicated, and the inner plug, can be effectively rectified by the rectifying plate in the narrow passage inside the plug body. As a result, the flow can flow into the dish-shaped shoulder of the container in a stable laminar flow state without any pulsation, and even if the dish-shaped shoulder of the container does not have a rectifying structure, it is just like a case without a stopper. Enables quiet and safe injection. Therefore, even if the beak-shaped liquid inlet portion of the dish-shaped shoulder portion is made open, it does not look unsightly. Even if the liquid outflow path through the communication passage within the plug is complicated and the outflow liquid is easily disturbed, this can be satisfactorily handled by combined use with a conventional rectifying structure provided on the dish-shaped shoulder of the container.
