Injection blow molding process and article

A process for injection blow molding a plurality of hollow thermoplastic articles, the process comprising the steps of:

• loading a sock preform of a first material composition onto a first core pin;
• injection molding a molten parison of a second material composition onto a second core sock of the first material composition and supported by a second core pin;
• blow molding an injection preform comprising an inner layer of the first material composition and an outer layer of the second material composition, the preform being supported by a third core pin;
• and
• wherein at least a portion of each step is carried out simultaneously.

A hollow thermoplastic article comprising:

• an interior surface of an inner layer comprising a first material composition;
• an exterior surface of an outer layer comprising a second material composition different than the first material composition;
• and
• wherein at least one of the inner layer and outer layer extends along a portion of the hollow thermoplastic article.

A hollow thermoplastic article comprising:

• an interior surface formed by an inner layer of a first material composition;
• an exterior surface formed by an outer layer of a second material composition different than the first material composition;
• and
• wherein the outside surface of the hollow thermoplastic article comprises a vestige and the outside surface is otherwise substantially seamless.
