Title:

INTERNAL TUBE FOR VACUUM INSULATED GLASS (VIG) UNIT EVACUATION AND HERMETIC SEALING, VIG UNIT INCLUDING INTERNAL TUBE, AND ASSOCIATED METHODS

Document Type and Number:

WIPO Patent Application WO/2020/141490

Kind Code:

A3

Abstract:

Certain example embodiments of this invention relate to vacuum insulated glass (VIG) units, and/or methods of making the same. The sealing tube or sealing material is provided within the VIG unit, thereby potentially eliminating the need for a protective cap and allowing for more freedom in handling, frame design, hybrid VIG construction, lamination, and the like. The sealing tube may be relocated to an internal area within a recessed pocket of a substrate at least in certain example embodiments. The VIG unit lacks a protruding pump-out tube or the like.
