Abstract: A glass panel unit includes a first pane of glass, and a second pane of glass facing the first pane of glass with the panes of glass spaced a predetermined interval apart. The glass panel includes a seal disposed between the panes of glass and joined to them in an airtight manner, and an interior space encompassed with the panes of glass and the seal. The glass panel unit includes: a partition wall disposed in the interior space and divides the interior space into a first space as a vacuum space and a second space; an air release vent formed in a first or second pane of glass and communicates with the second space; and a blocking member provided in the air release vent.

Abstract: 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.

Abstract: A multiple pane includes a pair of glass panels spaced by spacers and sealed at peripheries thereof. The multiple pane includes a plurality of spacers interposed between the pair of glass panels, a hermetic bond that hermetically bonds peripheries of the pair of glass panels to each other and a space between the pair of glass panels that is sealed so as to be in a reduced pressure state. Each of the plurality of spacers is a porous member provided on one glass panel of the pair of glass panels.

Abstract: The method includes: preparing a temporary assembly in which an inside space enclosed by first and second glass substrate and a frame is divided by a partition into a first space and a second space, a gas passage interconnects the first space and the second space, and an outlet interconnects the second space and an outside space obtaining a completed assembly by: converting the first space into an evacuated space by evacuating the first space through the gas passage, the second space, and the outlet and changing a shape of the partition to close the gas passage to form a separator to form a seal enclosing the evacuated space; and removing part including the second space from the completed assembly by cutting the completed assembly along a straight line to obtain a glass panel unit which is a predetermined part including the evacuated space.

Abstract: The multiple pane includes: a first glass panel; a second glass panel disposed facing the first glass panel with a predetermined interval in-between; and a hermetically-bonding member hermetically bonding peripheries of the first glass panel and the second glass panel to form a hermetically-enclosed space between the first glass panel and the second glass panel. The multiple pane further includes an adsorbing member which is fixed on a surface of the first glass panel so as to be inside the hermetically-enclosed space, has a height equal to or less than a length of the predetermined interval, and is for adsorbing a gas inside the hermetically-enclosed space. The hermetically-enclosed space is made to be in a reduced-pressure state.

Abstract: A multi-layer laminate includes a glass panel unit, an intermediate film, and a transparent plate. The transparent plate is assembled to the glass panel unit via the intermediate film. The glass panel unit includes a first and second glass panel, and an evacuated space. The evacuated space is interposed between the first and second glass panel. A method for manufacturing the multi-layer laminate includes a step. The step includes exhausting a gas from a bag, loaded with the glass panel unit, the intermediate film, and the transparent plate, to cause the bag to shrink and thereby assembling, using the bag thus shrunk, the glass panel unit and the transparent plate via the intermediate film. The step includes raising a pressure inside the bag from a pressure at an initial stage of heating while increasing a temperature of the intermediate film to a predetermined temperature at which the intermediate film softens.

Abstract: Provided are a glass panel unit and a method for manufacturing the glass panel unit, both of which are designed to overcome the problem of poor handleability of known glass panel units with no through holes. A glass panel unit includes a first panel, a second panel, a seal, and a boundary wall. The seal has a frame shape and hermetically bonds respective peripheral edge portions of the first panel and the second panel. The boundary wall partitions an internal space into a first space as a hermetically sealed evacuated space and a second space spatially separated from the first space. The first panel has a first through hole provided through a portion, corresponding to the second space, of the first panel. The second panel has a second through hole provided through a portion, corresponding to the second space and facing the first through hole, of the second panel.

Abstract: The assembling step is a step of preparing an assembly. The setting step is a step of setting a plurality of holder installation areas along an outer peripheral edge of the peripheral wall. The determining step is a step of determining a first area in which the slit and the peripheral wall are not adjacent to each other in the first area and a second area in which the slit and the peripheral wall are adjacent to each other. The installation step is a step of providing a holder in the first area without providing the holder in the second area.
