Abstract
Abstract A condensation proof glass assembly includes a cup of plastic material having an inner wall surface and a bottom wall, and a glass container having a similarly shaped outer wall surface and a bottom wall, snugly projected down into the cup, with the bottom walls spaced apart defining a spill over and condensation reservoir. A plurality of upright grooves in the outer surface of the container define corresponding ridges engaging the cup, with the grooves forming a series of drip channels conducting water to the reservoir.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
154 words
A condensation proof glass assembly comprising a cup of plastic material having an inner wall surface of predetermined shape, and a bottom wall; a glass container with a lower outer wall surface of substantially the same shape as the cup inner wall and having a bottom wall; snugly and frictionally projected down into said cup; said bottom walls being spaced apart defining a spill over and condensation reservoir; a plurality of upright substantially parallel grooves in the outer surface of the container defining corresponding ridges engaging said cup for a series of line contacts therewith; said grooves forming a series of drip channels conducting water to said reservoir; said grooves extending from intermediate the height to the bottom of the container; said cup extending over about the lower one half of the container; said grooves being concave in shape transversely of the container, of gradually increasing width; and decreasing depth towards the container bottom.
