发明名称 Process for molding a multiple layer structure
摘要 An injection molding process for making a multiple layer, plastic structure. A plastic sleeve is placed and then enclosed in a mold cavity. A flowing heated plastic is conducted into the mold cavity, radially inside the sleeve, and forced radially outward against the sleeve. The flowing plastic forces the sleeve outward and forms, with the sleeve, an integrally bonded laminated structure. The mold is opened and the plastic structure is removed, and this structure may then be reformed to form a container particularly suitable for containing beverages, foods, cosmetics, pharmaceuticals and chemicals.
