Abstract:
A thermally insulated beverage glass comprising:a generally tubular glass member having an inner sidewall supporting a threaded connection along an upper portion near a rim, said rim tapered out to form a drinking lip and said tubular glass member having an outer sidewall integrally forming a circular bottom support wall and a cylindrical-shaped inner sidewall and a substantially vertical annular outer sidewall; an outer sidewall; said inner sidewall forming a hollow interior designed to receive beverages, said inner sidewall inwardly offset relative to the outer sidewall so as to insertably engage within the outer sidewall along most of a vertical height, wherein said inner sidewall and said outer sidewall are joined in a threaded fashion together so as to form a drinking glass, wherein an interstitial space is defined between them which divides and thermally insulates the inner sidewall along both the bottom wall and circumferential sidewalls thereof; a decorative insulating material placed within said interstitial space.; and a first mating surface for engaging with a second mating surface, said first mating surface being an extending protrusion from a peripheral rim of said outer sidewall and offset inward by a notch in alignment with said second mating surface being an inwardly formed receiving cavity circumscribing the vertical circumferential sidewall of the tubular glass member, wherein said receiving cavity aligns with and receives said extending protrusion, such as when sealed will form a tortuous path to access the interstitial space; wherein upon engagement of said outer sidewall over and onto tubular glass member a seal is formed to isolate the interstitial space, forming an isolated airspace.
