ABSTRACT:
Reshaping of a nestable plastic container of substantially uniform wall thickness into a non-nestable container of substantially uniform wall thickness by substantially uniform radial and axial enlargement thereof. The nestable plastic container is heated below its rim portion to a predetermined temperature where the nestable container is readily deformable, the thus heated nestable container then being fixedly supported in a mold cavity having a non-nestable inner wall configuration, and subsequently expanding the nestable container against the non-nestable inner wall configuration of the mold cavity by differential fluid pressure to form a non-nestable container product.
