The invention concerns a glazing panel comprising first (5) and second (5) glass sheets linked together via at least one spacer (8) which holds them a certain distance apart from one another and, between said glass sheets (5), an inner space (4) comprising at least one first cavity (41), in which th
The invention concerns a glazing panel comprising first (5) and second (5) glass sheets linked together via at least one spacer (8) which holds them a certain distance apart from one another and, between said glass sheets (5), an inner space (4) comprising at least one first cavity (41), in which there is a vacuum of less than 100 mbar and which is closed by a peripheral seal disposed at the periphery of the glass sheets, around said inner space (4), the seal (1) being a metal seal rigidly connected respectively to the first and second glass sheets. According to the invention, the metal seal (1) further comprises at least one hollow metal tube (11) of which a first end (111) communicates with the inner space (4) and a second end (112) communicates with the outside of the panel, the second end (112) comprising means for blocking the tube. According to the invention, the tube comprises at least one gas trap (113) rigidly connected to the inside of the tube (11).

1. A glazing panel comprising: a first glass sheet and a second glass sheet that are associated together by way of at least one spacer that holds said sheets a certain distance apart, and, between said glass sheets, an internal space comprising at least one first cavity, in which space there is a va
1. A glazing panel comprising: a first glass sheet and a second glass sheet that are associated together by way of at least one spacer that holds said sheets a certain distance apart, and, between said glass sheets, an internal space comprising at least one first cavity, in which space there is a vacuum with a pressure of less than 100 mbar, said space being closed with a peripheral impermeable seal placed on a periphery of the glass sheets around said internal space, the impermeable seal being a metal seal securely fastened to the first and second glass sheets, respectively,wherein the metal seal furthermore comprises at least one hollow metal tube, a first end of which communicates with the internal space and a second end of which comprises a plug formed by pinching off the second end of the tube to form a cold weld,and in that the tube comprises at least one getter securely fastened to the interior of the tube. 2. The glazing panel as claimed in claim 1, wherein the getter comprises a coating placed on at least one portion of the internal surface of the tube. 3. The glazing panel as claimed in claim 1, wherein the getter comprises a tubular part provided to be inserted into the tube. 4. The glazing panel as claimed in claim 1, wherein the getter comprises an alloy of the following materials: zirconium;vanadium; andiron. 5. The glazing panel as claimed in claim 1, wherein the metal tube comprises at least one material selected from copper and its alloys, aluminum and its alloys and nickel and its alloys, in an unoxidized state. 6. The glazing panel as claimed in claim 1, wherein the metal seal is securely fastened by soldering to a first peripheral zone of the first glass sheet covered with a first adhesion coating and to a second peripheral zone of the second glass sheet covered with a second adhesion coating. 7. The glazing panel as claimed in claim 2, wherein the metal seal comprises a metal strip drilled with a hole into which the metal tube is placed. 8. A process for manufacturing the vacuum-insulated glazing panel as claimed in claim 1, comprising: associating together the first glass sheet and the second glass sheet by way of the at least one spacer that holds said sheets a certain distance apart, between said glass sheets,closing the internal space with the peripheral impermeable seal placed on the periphery of the glass sheets, around said internal space; andpumping down the internal space in order to obtain a vacuum with a pressure of less than 100 mbar,securely fastening the at least one getter to the interior of the tube; andblocking the second end of the tube by pinching off the end of the tube to form the cold weld once the pumping step has terminated. 9. The process as claimed in claim 8, further comprising coating at least one portion of the internal surface of the tube with the getter. 10. The process as claimed in claim 8, further comprising inserting the getter into the tube. 11. The process as claimed in claim 8, wherein the metal seal is securely fastened by soldering to a first peripheral zone of the first glass sheet covered with a first adhesion coating and to a second peripheral zone of the second glass sheet covered with a second adhesion coating. 12. The process as claimed in claim 8, wherein the metal seal comprises a metal strip, and the process further comprisingdrilling the strip in order to produce a hole, andinserting the metal tube into the hole. 13. A glazing panel comprising: a first glass sheet;a second glass sheet;at least one spacer that holds said first and second glass sheets apart;an internal space between said glass sheets, said space having a vacuum with a pressure of less than 100 mbar; andan impermeable metal seal placed on a periphery of the glass sheets enclosing said internal space, the impermeable metal seal being fastened to the first and second glass sheets,wherein the metal seal further comprises at least one hollow metal tube having first and second ends, a first end of said tube communicating with the internal space and the second end of the tube comprising a plug formed by pinching off the second end of the tube to form a cold weld, andwherein the tube comprises at least one getter. 14. The glazing panel as claimed in claim 13, wherein the getter comprises a coating placed on at least one portion of an internal surface of the tube. 15. The glazing panel as claimed in claim 13, wherein the getter comprises a tubular part provided to be inserted into the tube. 16. The glazing panel as claimed in claim 13, wherein the getter comprises an alloy of a material selected from the group consisting of zirconium, vanadium, and iron. 17. The glazing panel as claimed in claim 13, wherein the metal tube comprises at least one material selected from the group consisting of copper and its alloys, aluminum and its alloys, and nickel and its alloys, in an unoxidized state. 18. The glazing panel as claimed in claim 13, wherein the metal seal is fastened by soldering to a first peripheral zone of the first glass sheet covered with a first adhesion coating and to a second peripheral zone of the second glass sheet covered with a second adhesion coating. 19. The glazing panel as claimed in claim 13, wherein the metal seal comprises a metal strip having a hole into which the metal tube is placed.
