Abstract:

A seal section (50) in a package (1) has a steam-passage section (70) for allowing steam inside a tray (10) to escape externally.

An outer edge (72) of the steam-passage section (70) has a tapered tip and has a curved shape similar to the inner edge (71). The steam-passage section (70) has: a merging section (73) being a section between the tip of the outer edge (72) and the tip of the inner edge (71); and non-merging sections (74) being sections between the merging section (73) and general sections (60). The width of the non-merging sections (74) reduces from the general sections (60) towards the merging section (73).
