Abstract
Provided is a portion container whose detaching seal portion can be easily detached by a stress applied from a radial inner side based on an inside pressure of a container body, but can be hardly detached by a stress applied from the outside during distribution. Provided also are a seal head for sealing such container and a container sealed with using such seal head. The seal head includes pressing end portions for pressing a lid member against a flange of an opening. At least a portion of the pressing end portions is formed as an uneven projecting portion having different curvature radii in its cross sectional contour between a radial inner portion and a radial outer portion of the opening.
