The manufacturing cost can be significantly reduced. Further, since this screw structure and forming method can be used for all parts equipped with a screwing mechanism, it is of course excellent in versatility, and in particular, the solid cosmetic composition of the constitution as in the embodiment is dispensed. When applied to a container, not only can the number of parts be reduced, but the work of forming the screw groove can be easily performed by the user after it is sold as a product, so it is possible to simplify the assembly work. It is an epoch-making and meaningful invention that is effective.
