  In the above-described invention, the load applied to the hinge can be reduced and the cap can be made excellent in durability. However, the lid body may be difficult to open when the lid is opened. As a reason for this, in order to provide the liquid tightness of the spout in these hinge caps, a configuration in which a cap member of a lid is fitted to the spout of the cap body is generally used. In this form, the cap is generally formed of a synthetic resin with appropriate elasticity, so that the required liquid-tightness can be obtained. However, the cap body suspended from the back of the lid body is turned around to the standing spout. Since they are moved and fitted, in order to obtain sufficient liquid tightness, a relatively tight fitting of both is required. In addition, since the engagement between the guide surface and the sliding portion is added, it is difficult to expect easy opening when the lid is opened. The present invention has been made in consideration of such points, and proposes a hinge cap that can reduce the burden on the hinge, has sufficient liquid-tightness of the discharge port, and can be easily opened. .
