Abstract

A multi-layer co-extrusion blow molded plastic container adapted to be filled with a heat-sensitive nutrient and then retorted at relatively high temperatures to sterilize the contents thereof, the contents being agitated by rotating the container while it is being retorted and certain of the side walls being ribbed to both increase the surface area of the container and thus the heat transfer properties thereof and to aid in agitation of the contents whereby to minimize the time period the heat-sensitive contents must be exposed to such high temperatures for sterilization thereof, and the method of providing such a sterile container of heat-sensitive nutrient.
