A sealed container for use in cooking which has a heat-sealed portion partially opened when there is an increase in the internal pressure during heat cooking of various kinds of food including frozen foods contained therein so as to prevent rupture or deformation of the container, as well as the possibility of the contents boiling over as a result of rupture of the container. The sealed container of the present invention includes a container body provided at the opening thereof with a flange, and a lid, and a heat-sealed strip capable of peeling off is formed on the flange portion, at least one portion of the heat-sealed strip being formed in such a manner as to project toward the interior of the container, and the outer edge of the heat-sealed strip at that position and an innermost point of the outer edge of the heat-sealed strip being disposed on the inner side of a line connection the starting point of the projecting portion located on the inner edge of the container.

A sealed container for use in cooking including a heat-sealed dimensional peelable strip, a first portion of said heat-sealed strip extending linearly and substantially parallel to an edge portion of said container and a second portion projecting in a direction toward a central portion of the container so as to form a substantially V-shaped inwardly projecting portion, and the innermost point of the outer edge of the heat-sealed strip at the projecting portion being disposed on the inner side of a line connecting the starting points of said projecting portion located on the inner edge of the heat-sealed strip wherein the heat-sealing strength of the heat-sealed strip is between 0.1 and 5 kg/15 mm.
