To provide a bottle can excellent in its cap-openability, which is free from cracks and/or peel-offs in the protective coating provided on the outer surface side of its screw section, capable of being manufactured with a high productivity through manufacturing processes, enabling the reduction in costs of paint, and which, particularly in the case of a bottle can being sold in a hot vendor of an automatic vending machine, is easy even for old people or children to open the cap.

In the bottle can made of aluminum membrane plate, in which a cylindrical body portion and neck portion are integrally formed, only a top coating paint is used as a paint for the neck of a bottle can, a paint being constituted chiefly of wax-blended polyester resin, with a glass transition temperature (Tg) of the coated film being 60 to 100C.
