Abstract
A blow molded shipping container includes a hollow bottle of thermoplastic material defined by a continuous outer wall having a parting line formed during blow molding the bottle and a fill opening located on the parting line. An appurtenance of a material different from the thermoplastic material is integrally fused to the bottle during the blow molding of the bottle at a location of the bottle other than the parting line.

The method of manufacturing a blow molded shipping container comprising the steps of:
- providing a mold having first and second mold halves positioned together to define a mold cavity having a parting line between the mold halves;
- removably fastening a preformed appurtenance to one of the mold halves at a location other than the parting line;
- expanding a parison extruded sleeve of heat softened plastic in the mold to conform to the mold cavity and to fuse around the appurtenance to securely heat bond the appurtenance to the plastic to form a shipping container;
- and
- removing the shipping container from the mold cavity with the appurtenance being released from the mold half.
