The above-mentioned conventional cap with a mill has a large number of parts and the parts must be joined by an adhesive, so that the assembling work is complicated and the adhesive hardens. The production efficiency was poor because it was necessary to wait for it. In addition, the internal teeth and the external teeth are made of ceramic or metal, so that the cost is high, and when discarded, the cap is mixed with metal or ceramic, which is not suitable for material recycling. For example, when a glass container is reused as cullet, there is a possibility that metal or ceramic is mixed in the cullet.

According to the present invention, the internal teeth and the external teeth are made of plastic to reduce the cost, improve the joints of the members, reduce the number of parts, simplify the assembling work, and improve the production efficiency. The purpose of this is to provide a cap with a mill made of plastic, which is convenient for recycling.
