Composite container with stabilized base

A composite container formed at least in part by blow molding from a plastic parison with biaxial stretching, comprising:

• a base having a bottom including a central opening, side walls and an open top forming an edge;
• a blow molded plastic container body formed from said parison extending into said base through the open top to form double side walls and a double bottom, said parison forming a plug in said opening in said base to anchor said bottom during the forming of said body;
• and
• a peripheral shoulder defining the upper portion of the container body and mating with said edge,
• whereby said double side walls and base are thick relative to said shoulder.

A composite container formed at least in part by blow molding from a plastic parison with biaxial stretching, comprising:

• a base having a bottom, side walls having a beveled portion, and an open top forming an edge;
• a blow molded plastic container body formed from said parison extending into said base through the open top to form double side walls and a double bottom;
• and
• a peripheral shoulder defining the upper portion of the container body and mating with said beveled portion of said sidewalls,
• whereby said double side walls and base are thick relative to said shoulder.

A composite container formed at least in part by blow molding from a plastic parison with biaxial stretching, comprising:

• a base having a bottom, side walls and an open top forming an edge, wherein at least one of said sidewalls is of reduced height relative to a second of said sidewalls;
• a blow molded plastic container body formed from said parison extending into said base through the open top to form double side walls and a double bottom;
• and
• a shoulder defining the upper portion of the container body, said shoulder including a peripheral lip to mate and substantially cover the edge including along said reduced height sidewall;
• whereby said double side walls and base are thick relative to said shoulder.
