Patent ID: 8821677

Claim:
A method of manufacturing a hermetic container, comprising steps of: arranging a circumferential sealing member having a plurality of straight portions and a plurality of coupling portions in an alternate arrangement between a pair of glass members, so as to form an assembly structure having an internal space between the pair of glass members; applying an entire pressurizing force to the circumferential sealing member along a thickness direction of the circumferential sealing member with a negative differential atmospheric pressure in the internal space relative to an exterior of the assembly structure; applying a local pressing force to each of the plurality of the coupling portions along a thickness direction of the circumferential sealing member such that each of the plurality of the coupling portions is pressed with higher strength than the straight portions; and moving a local heating light spot of a local heating light along the circumferential sealing member during a period that the circumferential sealing member is applied with the entire pressurizing force and each of the plurality of the coupling portions is applied with the local pressing force.
