The mold assembly comprises a core member, a first cavity member that cooperates with the core member to form a first mold cavity section that is shaped to mold the bottom and side walls of the container, and a second cavity member that cooperates with the core member and the first cavity member to form a second mold cavity section that is an extension of said first mold cavity section and is shaped to mold the rim section of the container.
