Abstract:
1. A method for forming a vent port in a glass panel, the vent port discharging gas from a sealed space to the outside and being formed in either one of a pair of plate glasses which are separated from each other in a thickness direction to form the sealed space therebetween, the method comprising: forming an exhaust hole in either one of the plate glasses; vertically inserting a vent pipe-shaped sealant member into an upper portion of the exhaust hole, wherein the sealant member comprises a heterogeneous structure and wherein a portion thereof adjoining the plate glass has a lower softening point than a portion not adjoining the plate glass; discharging gas from a space between the plate glasses to the outside; heating the sealant member such that the sealant member becomes a fluid and the exhaust hole is closed by the sealant member having collapsed after being heated; and solidifying the sealant member remaining in the exhaust hole to ensure good sealing properties.
