MULTILAYER GLASS FOR ADJUSTING INTERNAL PRESSURE, PRESSURE ADJUSTING METHOD OF MULTILAYER GLASS FOR ADJUSTING INTERNAL PRESSURE, AND BAG FOR ADJUSTING INTERNAL PRESSURE

摘要

PROBLEM TO BE SOLVED: To provide a multilayer glass for adjusting internal pressure, a pressure adjusting method of the multilayer glass for adjusting internal pressure, and a bag for adjusting internal pressure which are capable of eliminating expansion of a hollow layer caused by an elevation difference and preventing leakage of gas sealed in the hollow layer.;SOLUTION: Included are: a multilayer glass 10 provided with a hole part 36 for establishing a fluid communication between a hollow layer 16 and outside air, the multilayer glass being configured to be sealed at an outer side of a spacer 14 and a primary seal member 18, the outer side excluding a surrounding space 56 surrounding the hole part 36, by a secondary seal member 20; a bag 38 having a connecting pipe 40 detachably connected to the hole part 36; and a plug member 42 mounted in advance in an internal space 48 of a bag body 38 including the connection pipe 40 under a state that the hollow layer 16 and the internal space 48 are in fluid communication with each other while the connection pipe 40 is connected to the hole part 36.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2020,JPO&INPIT
