PURPOSE:To make it possible to feed a synthetic resin raw material which is necessary for press-molding of a ring-shaped liner as previously specified and with sufficiently high speed by feeding automatically a synthetic resin raw material into a sleeve member of a press tool assembly when a molding device is transferred through a resin raw material receiving region. CONSTITUTION:When a molding device 8 passes through a container cover shell- receiving region 10 by rotating a rotary supporting body 6 of a molding apparatus main body 2, a press tool assembly and an anvil constituting the molding device 8 are separated each other in the vertical direction. While the molding device 8 is moved from the container cover shell-receiving region 10 to a resin raw material receiving region 12, the anvil 94 is gradually made into a resin and the lower end part of the press tool assembly is made simple in a container cover shell 32. Then, the molding device 8 is moved through the resin raw material receiving region 12, a synthetic resin raw material under softened and molten condition is fed to the press tool assembly. While the molding device 8 is moved through a molding region 14, the synthetic resin raw material is forcedly fed to a required position of the inner face of the ceiling wall of the container cover shell 32 and is molded into a ring-shaped liner. |
