Thermally insulated glass bottle

A thermally insulated bottle comprising:

• a generally tubular member having an inner sidewall supporting a threaded connection along an upper portion near a neck, said neck tapered upward, and said tubular 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 said 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 bottle, wherein an interstitial space is defined between them providing division and thermal insulation to said inner sidewall along both a bottom wall and circumferential sidewalls thereof;
• 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 said vertical circumferential sidewall of said tubular 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 said tubular member a seal is formed to isolate said interstitial space, forming an isolated airspace.
