Abstract
The present disclosure provides vacuum insulated articles having two—or more—insulated volumes at reduced pressure. An article may include a first vent communicating with a first insulating space, a second vent communicating with a second insulating space, a first circular insulation seal sealing the first insulating space at the first vent; and a second circular insulation seal sealing the second insulating space at the second vent. Also provided are methods of fabricating vacuum insulated articles.
Claims2
A vacuum insulated article, comprising:
- an outer wall, an inner wall, and a middle wall, each of the outer wall, the inner wall, and the middle wall having a cylindrical shape that are concentric to each other, an area between the inner wall and the middle wall forming a first insulating space, and an area between the middle wall and the outer wall forming a second insulating space;
- a first circular ring arranged between the inner wall and the middle wall, the first circular ring having a first beveled edge circularly arranged around the first circular ring facing at least one of the inner wall and the middle wall, a first vent formed at the first beveled edge communicating with the first insulating space;
- a second circular ring arranged between the middle wall and the outer wall, the second circular ring having a second beveled edge circularly arranged around the second circular ring facing at least one of the inner wall and the middle wall, a second vent formed at the second beveled edge communicating with the second insulating space;
- a first circular insulation seal sealing the first insulating space at the first vent;
- and
- a second circular insulation seal sealing the second insulating space at the second vent.
