Abstract:
1. A vacuum container comprising; a first and second substrate of relatively the same dimensions and areas; a peripheral sear positioned about the outer periphery of each substrate for bonding said first substrate to said second substrate to form a composite stacked member of a given height with said first substrate bonded to said second substrate with said seal sandwiched between said substrates, said substrates separated one from the other by the width of said seal to create an internal hollow between said substrates, said seal having an elongated aperture between said substrates; a getter box having a top and a bottom surface with a first and a second side joining said top and bottom surfaces, with a front opening of said box having a length greater than the length of said aperture and a width greater than the thickness of the composite member and the height of said box is larger than the height of said composite member, said box joined to said substrates to cover and enclose said aperture in said seal wherein said box has extending projections to overlie said first and second substrates to secure said box to said substrates by joining said projections to said substrates with a glass bond, said box having a vacuum aperture in one side with an evacuation tube of a given diameter opening to enclose said vacuum aperture, said tube joined to said box about said opening and having a sealed end remote from said box, said getter box having a getter source in said box hollow to absorb any residual gasses in said display hollow after said display hollow has been evacuated to a desired vacuum before sealing said end of said evacuation tube, wherein the area of the aperture is equal to or greater than π(D/2)
