PCT No. PCT/JP89/00500 Sec. 371 Date Mar. 16, 1990 Sec. 102(e) Date Mar. 16, 1990 PCT Filed May 18, 1989 PCT Pub. No. WO89/11426 PCT Pub. Date Nov. 30, 1989.A sealed vessel is formed by heat-sealing a lid to a flanged vessel proper while forming a coating of a composition prepared by dispersing a small amount of an acid-modified olefin resin in a thermosetting resin on one of the faces to be heat-sealed and forming an olefin resin layer on the other face to be heat-sealed. The heat-sealed portion of this vessel has excellent heat resistance and excellent pressure resistance, and opening in the heat-sealed faces can be easily accomplished by hands.
