The invention relates to a glass panel including a first (5) and a second (5) glass sheet combined together via at least one spacer (8) that keeps the glass sheets at a certain distance from each other, wherein an inner gap (4) between said glass sheets (5) includes at least a first recess (41) in w
The invention relates to a glass panel including a first (5) and a second (5) glass sheet combined together via at least one spacer (8) that keeps the glass sheets at a certain distance from each other, wherein an inner gap (4) between said glass sheets (5) includes at least a first recess (41) in which a vacuum of lower than 1 mbar is formed, said recess being sealed by a peripheral seal arranged at the periphery of the glass sheets around said inner space (4), the seal (1) being a metal seal rigidly connected to the first and second glass sheets, respectively. According to the invention, the metal seal (1) further includes a means (11) for placing the inner gap (4) in communication with the outside of the panel, wherein said communication means can be sealed.

1. A glazing panel, comprising: a first glass sheet and a second glass sheet joined together via at least one spacer holding the first and the second glass sheets at a certain distance from one another, andbetween the first and the second glass sheets, an internal space comprising a first cavity,wherein the first cavity has a vacuum of less than 1 mbar and is closed by a peripheral seal arranged on periphery of the first and the second glass sheets around the internal space,whereinthe peripheral seal is a metal seal fixed to the first and second glass sheets respectively,the metal seal comprises a sealable connector connecting the internal space with outside of the glazing panel,the connector comprises a hollow metal tube, of which a first end connects with the internal space and a second end connects with outside of the glazing panel,the second end comprises a sealer for sealing the metal tube, andthe sealer comprises a plug formed by pinching the second end of the metal tube forming a cold weld. 2. The glazing panel according to claim 1, wherein the metal tube comprises at least one material selected from the group consisting of copper, a copper alloy, aluminium, an aluminium alloy, nickel, and a nickel alloy, in a non-oxidised state. 3. The glazing panel according to claim 1, wherein the internal space further comprises a second cavity arranged between the metal seal and an edge of the glazing panel, andthe second cavity is closed by the metal seal. 4. The glazing panel according to claim 3, wherein the first end of the metal tube is present within the second cavity. 5. The glazing panel according to claim 1, wherein the metal seal is fixed by welding to a first peripheral zone of the first glass sheet covered with a first adhesive coating and to a second peripheral zone of the second glass sheet covered with a second adhesive coating. 6. The glazing panel according to claim 1, wherein the metal seal comprises a metal strip pierced by a hole, in which the metal tube is present. 7. The glazing panel according to claim 6, wherein the metal tube is fixed to the metal strip by welding. 8. A method for manufacturing a vacuum glazing unit according to claim 1, the method comprising: joining together a first glass sheet and a second glass sheet via at least one spacer, which holds the first and the second glass sheets at a certain distance from one another, and forming an internal space comprising a first cavity between the first and second glass sheets;closing the internal space via a peripheral seal arranged on periphery of the first and the second glass sheets and around the internal space;placing the internal space under vacuum in order to obtain a vacuum of less than 1 mbar; andpinching the second end of the metal tube to seal the metal tube and to form the cold weld. 9. The method according to claim 8, wherein the metal seal is fixed by welding to a first peripheral zone of the first glass sheet covered with a first adhesive coating and to a second peripheral zone of the second glass sheet covered with a second adhesive coating. 10. The method according to claim 8, wherein the metal seal comprises a metal strip, andthe method further comprises:piercing the metal strip to form a hole andinserting the metal tube into the hole. 11. The method according to claim 10, wherein the metal tube is fixed to the strip by welding. 12. A glazing panel, comprising: a first glass sheet and a second glass sheet joined together via at least one spacer holding the first and the second glass sheets at a certain distance from one another, andbetween the first and the second glass sheets, an internal space comprising a first cavity,wherein the first cavity has a vacuum of less than 1 mbar and is closed by a peripheral seal arranged on periphery of the first and the second glass sheets around the internal space,whereinthe peripheral seal is a metal seal fixed to the first and second glass sheets respectively,the metal seal comprises a sealable communication means for connecting the internal space with outside of the glazing panel,the communication means comprises a hollow metal tube, of which a first end connects with the internal space and a second end connects with outside of the glazing panel,the second end comprises a means for sealing the metal tube, andthe sealing means comprises a plug formed by pinching the second end of the metal tube forming a cold weld.
