Abstract:
Provided are: a portion container with which a detachment seal part is readily detached as a result of stress exerted from an inner side of a container main body in a radial direction by internal pressure, and with which the detachment seal part is not readily detached as a result of stress exerted from an outer side during distribution; a seal head used to seal said portion container; and a container sealed using said seal head. This seal head is provided with pressing end parts (31A, 31B) for pressing a lid body (9) against a flange (5) of an opening of a container main body having contents accommodated therein, in order to weld the lid body (9) to the opening. At least one of the pressing end parts (31A, 31B) is formed as an irregular protrusion (31A) having a cross-sectional outline with different curvature radii, said cross-sectional outline being between a site (Q1) at an inner side of the opening in the radial direction and a site (Q2) at an outer side of the opening in the radial direction.
