When closed, there was a problem that it would slip into the container and the seal would weaken partially.

In addition, the lid is supported by a hinge provided on the rear side of the spout, and when the lid is closed from the maximum opening angle, the waterproof packing placed on the lower surface of the lid is located behind the spout. From the part, contact the upper flange of the container one by one,
When the hook part of the lid is finally fixed to the hook fixing part of the spout, it is pressed by the waterproof packing for the first time to seal the entire upper end flange part of the container. In this case, the hinge of the spout is used. Since the portion is formed in an L shape, for example, when the waterproof packing comes into contact with the upper end flange portion of the container while being displaced and the lid body is fixed at that position, the lid body is regulated rearward later. However, its position does not return to its original position, and the upper flange of the container and the waterproof packing are still removed.

Further, if the spout and the lid are configured so as to be position-controlled before the hook portion of the lid is fixed to the hook fixing portion of the spout, the closing force of the lid becomes heavy, resulting in poor operability. Was becoming. Also, in terms of appearance, the step between the spout and the lid was large, making it unsightly.

In view of such a problem, the present invention regulates the direction in a direction before the waterproof packing abuts on the upper flange portion of the container in the relationship between the upper flange portion of the container and the waterproof packing provided on the lower surface of the lid. In addition, the purpose is to center the upper end flange of the container and the waterproof packing of the lid with the spout and the lid.
