Abstract
An object is to provide a microwave container configured to precisely discharge vapor from a vapor-discharging part to avoid any vapor discharge from the remaining portions, and the microwave container includes: a container main body having an opening in its upper portion; a flange part formed to extend outwardly from the opening of the container main body; and a heat-seal part in a rib shape formed over the entire periphery of an upper surface of the flange part and heat-sealed to a film-shaped lid member for sealing the opening, wherein the heat-seal part includes a first heat-seal part for discharging vapor generated in the container main body by breaking the heat seal with the lid member when the vapor reaches a predetermined pressure, and a second heat-seal part wider than the first heat-seal part.
