Abstract
Layered thermoplastic articles (36) and a method for forming layered thermoplastic articles are provided. The method involves forming a layered, thermoplastic parison, followed by blow molding the parison in a mold cavity (10, 12) to form a desired configuration of hollow article (36). The blow molded articles (36) can be of any configuration achievable with known blow molding technology. Every section of the article (36) can be layered, or the article (36) can have selectively intermittent layered sections. The containers typically are used for storing and dispensing liquids and are of one-piece construction. In accordance with this invention, the thermoplastic materials (24, 26) are of a type which are incompatible.
