Description of the Related Art Recently, a supporting cylinder is erected from a base cylinder that is fitted in a liquid-tight manner to the neck of a container body, and a holding cylinder having front and rear end face openings is attached to the upper end of the supporting cylinder so as to communicate with the inside of the supporting cylinder. With the plug body,
It is composed of a member with a handle in which the middle part of the nozzle with the rear end face closed is inserted into the holding cylinder in a liquid-tight manner, and the handle is projected outward from the rear side of the nozzle. When the nozzle is rotated with respect to the nozzle, the through hole provided in the nozzle and the liquid introduction hole at the upper end of the support cylinder communicate with each other, and the liquid in the container flows out from the nozzle, and when the handle is turned to the other side, the nozzle is rotated. A liquid pouring plug is provided which is arranged so as to block the liquid outflow by blocking the through hole and the liquid introduction hole by the rotation. In such a liquid pouring stopper, if a handle that touches another object during transportation stands up from the stopper body, it may become bulky or the handle may break. A separate stopper having a substantially U shape is fitted into the support cylinder to lock the handle at the closed position.

Therefore, in the above-described conventional liquid pouring stopper, there is a problem in that, after being attached to the container body, when another object comes into contact with the handle to rotate, the stopper is opened and the liquid flows out from the liquid storage container. It was to solve this problem,
The stoppers may be used without being discarded, but a strong force is required to elastically deform the pair of locking plates described above, which makes the removal and installation of the stoppers cumbersome, and when the liquid is poured, It is necessary to pay attention to the storage location so that the stopper removed from the main unit will not be lost.
It had the drawback of being annoying.

The present invention has been made in view of the above circumstances and provides a stopper main body and a member with a handle constituting a liquid pouring stopper.
By providing one and the other of the concave and convex engaging means that can be engaged with each other only when the cap is closed, it is not necessary to prepare a separate stopper at the time of factory shipment, and the liquid pouring plug can be used not only for transportation but also for the container body. The handle can be locked in the closed position even after it is attached to the
Further, the engagement and disengagement of the concave and convex engaging means can be facilitated. Further, when the stopper is opened, only the engagement of the concave and convex engaging means is released to unlock the member with the handle to open the stopper. (EN) Provided is an easy-to-operate liquid pouring stopper which can be operated.
