摘要： A glass panel unit includes: a first panel including a glass pane; a second panel including another glass pane; a sealing portion; an exhaust port; and a printed portion. The second panel is arranged to face the first panel. The sealing portion is formed in a frame shape and hermetically bonds respective peripheral edge portions of the first and second panels to create an evacuated, hermetically sealed space between the first panel and the second panel. The exhaust port is provided for one panel selected from the first and second panels. A port sealing member hermetically seals the exhaust port. The printed portion is provided for the other panel selected from the first and second panels. The printed portion is located in an area, facing the exhaust port, of one surface of the other panel. The one surface either faces toward, or faces away from, the hermetically sealed space.

摘要： A method for manufacturing a glass panel unit includes a glue arrangement step, an assembly forming step, a first melting step, an evacuation step, and a second melting step. The first melting step includes melting a hot glue, bonding a first and second panel with the glue, and forming an internal space. The first melting step includes a first temperature raising step, a first temperature maintaining step including maintaining the temperature of the assembly at a temperature equal to or higher than a softening point of the hot glue, and a first temperature lowering step, which are performed in this order. The first temperature lowering step includes: an anterior temperature lowering step including lowering the temperature of the assembly; a middle temperature maintaining step including maintaining the temperature of the assembly; and a posterior temperature lowering step including lowering the temperature of the assembly, which are performed in this order.

摘要： A glass panel unit assembly includes: a pair of glass substrates arranged to face each other; a peripheral wall; a partition; an air passage; and an evacuation port. The peripheral wall has a frame shape and is disposed between the pair of glass substrates. The partition partitions an internal space, surrounded with the pair of glass substrates and the peripheral wall, into a first space and a second space. The air passage connects the first space and the second space together. The evacuation port connects the second space to an external environment. The partition is lower in height than the peripheral wall.

摘要： A glass panel unit includes: a sealing member arranged between a first panel and a second panel, which are arranged to face each other with a predetermined gap left between themselves, to hermetically bond the first panel and the second panel together; and an internal space sealed hermetically with the first panel, the second panel, and the sealing member. The glass panel unit further includes a spacer arranged in the internal space so as to be in contact with the first panel and the second panel. The spacer includes a plurality of resin layers that are stacked one on top of another in a direction in which the first panel and the second panel face each other. At least any two of the plurality of resin layers have different elastic moduli.

摘要： A method for manufacturing a glass panel unit includes an assembling step, a bonding step, a gas exhausting step, a sealing step, and an activating step. The bonding step includes melting a peripheral wall in a baking furnace at a first predetermined temperature to hermetically bond a first glass pane and a second glass pane together with the peripheral wall thus melted. The gas exhausting step includes exhausting a gas from an internal space through an exhaust port in the baking furnace to turn the internal space into a vacuum space. The sealing step includes locally heating to a temperature higher than a second predetermined temperature, and thereby melting, either a port sealing material or an exhaust pipe to seal the exhaust port and thereby obtain a work in progress. The activating step includes activating a gas adsorbent after the sealing step to obtain a glass panel unit.

摘要： An assembly includes: a pair of glass substrates; a peripheral wall disposed between the glass substrates; partitions; an evacuation port; and air passages. The partitions are provided to partition an internal space, surrounded with the glass substrates and the peripheral wall, into an evacuation space and a ventilation space. The evacuation port connects the ventilation space to an external environment. The air passages are used to evacuate the evacuation space through the evacuation port. The air passages include particular air passages arranged in a second direction perpendicular to a first direction, in which the glass substrates face each other, to constitute a ventilation path running through the internal space in the second direction.

摘要： A glass panel unit manufacturing method includes a punching step and a pillar mounting step. In the punching step, a punch punches at least one of a plurality of portions from a base material of a sheet to form at least one pillar. Each of the plurality of portions is surrounded by a corresponding one of a plurality of loop-shaped grooves in the base material. In the pillar mounting step, the at least one pillar is mounted on a surface of a first substrate including a glass pane.

摘要： A glass panel unit manufacturing method includes a bonding step, a pressure reducing step, and a sealing step. The bonding step includes bonding together a first substrate and a second substrate with a first sealant to create an inner space. The pressure reducing step includes producing a reduced pressure in the inner space through an exhaust port that the first substrate has. The sealing step includes irradiating a second sealant, inserted into the exhaust port, with an infrared ray through a region, where a low emissivity film is nonexistent, of the second substrate.

摘要： The objective is to propose a production method of multiple panes which can be simple and nevertheless produce a multiple pane in its finished state which does not include any undesired protrusion from an external surface of a glass panel. The production method includes: hermetically bonding, with a sealing member, peripheries of paired glass panels disposed facing each other at a predetermined distance to form a space to be hermetically enclosed between the glass panels; evacuating air from the space through an outlet to make the space be in a reduced pressure state; subsequently dividing the space by a region forming member disposed inside the space to form a partial region which do not include the outlet; and subsequently cutting out the partial regions by cutting the pair of glass panels.
