APPARATUS FOR MAKING A MULTI-LAYER INJECTION BLOW MOLDED CONTAINER
Apparatus for making a rigid container by injection molding a parison having plural layers of polymers including interior and outer layers in an injection mold (20) having a core pin (10A, 10B). A blow mold (30A, 30B) is used to blow the parison to the final shape of the container. Control devices (100, 110, 115, 120) exercise control over each of the plural plasticators (82A, 82B, 82C) and rams (70A, 70B, 70C) for the plural polymers so as to produce uninterrupted layers extending throughout the walls of the parison and to insure that the interior layers are completely encapsulated within the outer layers.
