Abstract: A lidded container, which enables contents to be poured from a specific part, is provided. A closing seal portion joining a lid to a flange portion of a container comprises: a main seal portion having a first end and a second end; and a projecting seal portion having one end and the other end connected to the first end and the second end of the main seal portion and projecting toward the opening of the container. A width of a leading end portion which is a portion of the projecting seal portion, which is closest to a center point of the opening of the container, is smaller than a width of an opposing portion which is a portion of the main seal portion, which intersects with a center line passing through the leading end portion of the projecting seal portion and the center point of the opening of the container.

Abstract: The present invention provides a lidded container which, even when a flange portion of the container warps during microwave heating, can prevent a contact between the flange portion and a lid and allows steam to pass from a steam escape mechanism. The lidded container is provided with a container having an opening and a lid which covers the opening and is joined to the container. The container is provided with a bottom portion, a side portion standing upright from the bottom portion, and a flange portion which is continuously connected to an upper portion of the side portion and includes a first plane. A circumferential seal portion is formed between the lid and the first plane of the flange portion. The seal portion is provided with a main seal portion and a protruding seal portion protruding inward with respect to the main seal portion.
