Abstract
A rigid container is made by injection molding a parison having plural layers of polymers. The parison is blow molded to the final shape of the container. Control during injection is exercised over each of 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.
