<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a bottle can which eliminates the non-conformity such as difficulties to open bottle caps due to the high valve rotation torque before cutting the bridge and which reduces the rotation torque so as to easily open the bottle caps by reducing the frictional resistnce between the synthetic resin liner of caps and the inner surface coating of the curl top surface that is not conventionally recognized as a problem, and to provide a bottle can manufactured by the method. <P>SOLUTION: The inner coating method of the bottle can is characterized by applying the inner coating to which particulate wax is added on the opening including at least the curl top surface of the bottle can of the inner side of a bottomed cylindrical tube for aluminum bottle can having a thread for screwing the cap and the bottle can manufactured by the method is obtained. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
