Because the process used by the present invention inserts a mold core with predefined pattern so that the patterns on the mold core can be formed on the inner surface of the monolithically formed object manufactured during the blow molding process. As such, the problems of complex and time-consuming steps and poor economical result associated with conventional techniques are improved.
