Filed: 2002-09-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a multilayered container having heat resistance, impact resistance at low temperature and further sufficient heating in a microwave oven.  <P>SOLUTION: The multilayered container A has a gas barrier layer and a foamed resin layer made of a polyolefin-based resin, wherein an expansion ratio of the resin layer is 1.3 to 2.5 and a ratio of the layer is 50 to 98% of a total layer thickness. A blow-molded multilayered container consists of the multilayered container A including a base, a barrel and an opening and a flange A13 formed along the periphery at the upper end of the barrel, and has its opening hermetically sealed with a multilayered laminate film on the flange with contents filled in the container, to serve as a container for use in a microwave oven. The container A thus has heat resistance, impact resistance at low temperature and further sufficient heating in the microwave oven. In addition, the contents in the container are easy to get warm but difficult to cool. Since the surface temperature of the container is lower than the internal temperature and heat load when in contact with the container is small, the container is highly useful for freezing (also for cooling) for those reasons or the like.  <P>COPYRIGHT: (C)2004,JPO
