To this end, cosmetic containers and the like, as shown in Figure 1a, it is common to screw the cap 3 to the spout 2 of the container (1).

However, because of the structural characteristics of the screw coupling method is difficult to maintain the confidentiality of the contents, there is a high possibility that the contents leak during the distribution process. Accordingly, the cosmetic container or the like has an auxiliary cap 4 for confidentiality in the distribution process, etc. at the inlet of the container 1 at the time of shipment, and is shown in FIG. 1B when the product is actually used after the product is delivered to the consumer. After opening the stopper 3, the auxiliary cap 4 is separated and discarded from the container 1, and only the stopper 3 is screwed to the spout 2 of the container 1 to be used.

However, such a conventional container cap 3 has a problem in that it is complicated to be provided with a separate auxiliary cap (4) for confidentiality in the distribution process.

The present invention has been made in view of the above problems of the conventional container closure, and an object thereof is to provide a container closure that can be used without discarding the auxiliary cap.

Another object of the present invention is to provide a container closure in which the sealing effect by the auxiliary cap is maintained even in actual use of the product.
