There is a cap described in No. 2. This cap is formed by forming a plurality of tears in a skirt portion to be fitted to a container and driving the tightening band in a state where the tightening band is fitted so as to reinforce the tear. Is cut off, and then the skirt portion formed with a plurality of tears is removed from the container.

This cap has a structure in which the hinge of the outer lid is broken, the lid is separated, and then the stopper is locked to the outer lid and the outer lid is removed. are doing.

を外し易くするとシール性に課題を生じることになる。In a two-piece cap developed for the purpose of sorting and collecting, it is an important issue how to easily remove the outer lid and the inner lid while increasing the fitting force of the outer lid. there were. In general, in a two-piece cap, the inner lid is formed of a flexible material in order to enhance the sealing property, and the outer lid is formed of a hard material in order to increase the durability at the time of opening and closing. In such a two-piece cap, there is a problem in durability when the outer lid is formed so as to be easily removable, and a problem in sealing performance when the inner lid is easily removed.

とはできない。In the conventional two-piece cap, the former cap is formed by forming a plurality of cracks in a skirt portion to be fitted to a container, and driving the tightening band in a fitted state so as to reinforce the cracks. I have. Although this cap has a two-piece structure, the cap body and the tightening band are merely separate components. That is, in this cap, since the inner lid fitted to the container and the outer lid covering the inner lid are integrally formed, the material of the inner lid and the outer lid cannot be changed. Therefore, this cap has a fundamentally different structure from a two-piece cap in which the material of the inner lid and the outer lid is different, and uses a two-piece cap using an inner lid for improving the sealing property and an outer lid for improving the durability at the time of opening and closing. In addition, this cap structure cannot be adopted.

いった不都合もあった。[0008] On the other hand, the latter cap has a configuration that can be adapted to a two-piece cap in which the materials of the inner lid and the outer lid are different. However, after use, the hinge of the outer lid is broken to separate the lid, and then the outer lid is removed using a bottle opener. Therefore, if the strength of the outer lid is increased, the operation of separating the lid by breaking the hinge of the outer lid must be difficult. In addition, when the cap is discarded, a bottle opener must be used, and there is also a disadvantage that the cap cannot be separated without the bottle opener.

The object of the present invention is to provide a two-piece cap for collection that can be separated and collected very easily while increasing the fitting force of the outer lid, and that can enhance the sealing property of the inner lid and the durability of the outer lid. is there.
