Abstract

PROBLEM TO BE SOLVED: To prevent rupture of a container in advance by providing a part to be peeled off by the thermal contraction during the heating on at least one part of seal part to release the steam filled inside to the outer side without opening a hole before putting a packaged frozen food in a microwave oven. SOLUTION: A flange C1 ' is formed in a peripheral part of an opening of a cup-shaped container C1 , a packaged frozen food is stored, and a sealed part is formed by a top seal film T1 made of plastic. A small hole H1 of the dimension suitable for a vent is formed at least in one part of the top seal film T1 , and a label L1 made of the material which is larger in shrinkage by heat compared with the top seal film T1 , e.g. PET or PVC, is attached with the adhesive so as to cover the small hole 1. When the water content in the packaged frozen food is evaporated when heated in a microwave oven, and the internal pressure is increased and the temperature rises, the label L1 is automatically peeled, and the steam inside is discharged outside.
