PURPOSE:To manufacture a synthetic resin product with a hinge integrated with a synthetic resin film of superior flexibility by inserting a side edge section of the flexible synthetic resin film of superior flexibility having the melting point equivalent to or higher than that of two synthetic resin parts related each other and providing a hinge of the film between said two parts. CONSTITUTION:Both side edges of a synthetic resin film 3 having the melting point of equivalent to or higher than two synthetic resin parts 2 and 12 are inserted into their synthetic resin parts 2 and 12 related each other, and a hinge 4 constituted of the film 3 is provided between the resin parts 2 and 12. Thus, the resin film 3 inserted between the resin parts 2 and 12 is not fused with the resin parts 2 and 12 but is apparatus in the state of being bonded with the resin parts 2 and 12. |
