<< Prior Art >> Conventionally, in a container with a cap of this type, when the cap is removed from the container, the cap is configured to be pulled up, or the cap is formed of a flexible material to form a peripheral wall of the cap. It is well known that the cap is bent in the radial direction and the lower end of the peripheral wall is brought into contact with the inclined surface of the container so that the cap can be raised through the inclined surface.

<Problems to be solved by the invention> However, in the case of a container with a cap having the above-mentioned structure, in the former case, if the fitting strength between the cap and the container is increased, the sealing performance is improved, but a large force is required to remove the cap. On the contrary, if the fitting strength is weakened, the cap can be easily removed, but at the same time, the cap is apt to come off accidentally and the sealing performance is deteriorated.

Further, in the latter, since the cap is thinly made of soft synthetic resin so as to bend in the radial direction, an effective force for raising the cap is generated even when the cap peripheral wall is pushed and the lower end of the peripheral wall abuts on the inclined surface and slides. Difficult, so it could only be applied to those with a low fitting strength between the container and the cap.

The present invention has been made in view of the above-described problems, and its purpose is to improve the sealing performance and to be convenient in that the cap can be easily removed with a small force even if the fitting strength between the cap and the container is sufficiently increased. To provide a container with a cap.

<Means for Solving the Problems> In order to achieve the above object, in the present invention, a cap body is detachably attached to a container in a vertical direction by elastic fitting, and an inner cap is provided in the cap body. The inner cap is provided with flexible pieces that can be bent and deformed inwardly of the cap main body via a hinge portion so as to face each other, and a convex portion is formed on the outer surface of the flexible piece, and the convex portion is formed on the cap. When the flexible piece is exposed from the main body and at least one of the contact surface between the lower end of the flexible piece and the container is an inclined surface and the convex portion is pressed to bend the flexible piece inward, the inclined surface is inserted. In a container with a cap configured so that a component force for raising the cap body acts on the inner cap, the content of the contents is placed inside the inclined surface where the flexible piece and the container come into contact with each other. The opening tube of the container for extraction and the cap A sealing member that is provided on the ceiling side of the main body and seals the opening tubular portion, and an elastic fitting portion between the cap main body and the container is formed outside the sealing member.
