<p>PURPOSE:To manufacture a hollow molded product of superior glossiness, the contact site of which is slidable easily in the case the products are brought into contact each other during the transfer, and to be transferrable without delay and provide its molding method. CONSTITUTION:At least an outer surface 4a of a hollow molded container being in contact with cavity forming wall faces 5a is composed of polyester resin. In the molding method of the hollow molded container in which a specified parison 4 for hollow molding is positioned between cavity forming wall faces 5a facing each other in the mold opening state of molds 1 and 2, and compressed air is filled in the parison 4, the average roughness of center line of the cavity forming wall faces 5a is set at 0.25mum or less, and air in a cavity 3 located outside the parison 4 is sucked prior to the filling of compressed air into the parison 4.</p> |
