  • Patent number: 10808453
    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.

  • Publication number: 20200157876
    Abstract: A first substrate, having an evacuation port, and a second substrate are bonded together with a first sealing material in a frame shape interposed between them to create an internal space. The internal space is evacuated through the evacuation port, and the evacuation port is sealed up with the internal space kept evacuated. At this time, a second sealing material inserted into the evacuation port is heated and melted while being pressed toward the second substrate such that the evacuation port is sealed up with the second sealing material melted. The evacuation port and the second sealing material have dissimilar shapes when viewed along the center axis of the evacuation port in a state where the second sealing material has been inserted into the evacuation port but has not melted yet.
