Description of the Related Art There is known a cap with a lid portion in which a portion is elastically inverted so that a cap body opening can be opened and closed.

In addition to the above cap, a double cylindrical inner / outer leg tube which fits from the outer peripheral portion of the first top wall to the inner / outer surface of the mouth and neck of the container body is hung down, and at the same time, the pouring tube is discharged from the first top wall. The top wall portion which is erected and surrounded by the inner leg tube is surrounded by a thin line for breaking to form a removing plate portion, and a connecting piece is raised from a part of the outer periphery of the removing plate portion and a finger ring is attached to an upper end of the connecting piece. There is known a cap integrally formed of a synthetic resin material.

[0004]

[Problems to be solved by the invention]
Since it will not be opened unless the removal plate part that forms part of the integrally molded cap is removed by lifting the finger ring,
Although the sealing with the cap is reliable, after opening, the opened pouring cylinder must be opened and closed with a lid provided separately. In this regard, the former cap has the advantage of being able to open and close the cap opening by reversing the lid elastically, but the opening sealing mechanism before opening is not as good as the latter cap. Therefore, a cap having both of the features of both caps is desired. However, the former cap must be integrally molded with, for example, polypropylene, which has high refraction resistance. Even with the provided cap, the plate cannot be removed by tearing along the thin line for breaking.

The present invention has been devised to provide a cap having the features of the above two caps. The cap is securely sealed before opening the cap, and the opening and closing of the cap can be opened and closed by reversing the elasticity of the lid after opening. It is provided.
