    摘要: Method and apparatus for blow molding double-walled containers from thermoplastic polymers in which the inner and outer container parts are simultaneously molded in a single tandem mold in the same molding cycle to produce special single-piece molded container intermediates. The intermediate is then cut apart along specially provided cut lines to provide a continuous inner container and a multipiece outer container in which the inner container nests. Loose, molded or batt-type insulation may be employed in annular space between the outer shell and the inner container. The outer container parts, bottom and top, are designed to snap-fit together. A carrying or pouring handle may optionally be molded into the outer shell part, or spout to the inner, or they may be added as separate pieces.
