Document Type and Number:

Japanese Patent JPS60120030

Kind Code:

A

Abstract:

Improved plastic containers and process for their production are disclosed. In one embodiment, containers are blow molded in a first hot blow mold, then reblown to a larger size in a second cold mold of larger volume than the first hot mold. Such containers have improved physical properties, particularly very high hoop yield stresses. In a second embodiment, containers are blow molded in a hot blow mold, then reblown to a larger size in a second hot blow mold. Such containers show high resistance to shrinkage and gross deformation in shape upon exposure to high temperatures.
