Abstract

PURPOSE:To prevent contents of a container body from spilling over on unsealing thereof, by deforming inwardly a bending portion of the container body having a restoring force at the bottom thereof and forming the bending portion bended outsides and by sealing the opening of the body by a lid under said conditions. CONSTITUTION:The bottom 14 of a container body 12 is shaped to have a bending portion 14a bended outside at the center for a restoring force. Namely the bending portion 14a is deformed inwardly at the head 38a of a bolt 38. Accordingly the inside volume of the container body 12 is decreased, compared with the original form. In such conditions, an upper base 40 and heating members 52, 54 etc., are displaced downwards and an opening 12a of the container body 12 is sealed by a lid 22, bonding the sealing portion 22a of the lid 22 to the sealed portion 18a of a brim 18 by the heating member 52 and further the adhered portion 22b of the lid 22 is welded with the adhered portion 20a of a lever 20. Therefore, when the container body is taken out, it results in a decompressed condition in its inside because of recovery to the original form due to the restoring force thereof.
