Abstract
Abstract A glass case fabricated from a sheet of flexible and stretchable closed cellular elastomeric material having a stretchably resilient fabriclike outer skin bonded to one side thereof. The sheet of material is folded over upon itself to form a rectangular enclosure. The abutting edges of the material are secured together by gluing or stitching along the end and side of the case, one of the ends being left open to permit insertion and removal of the glasses into and from the case. The volume and density of the closed cellular elastomeric material are such that the case will float in water for an extended period of time despite the presence of a pair of glasses therein.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
An eye glass case comprising a sheet of flexible, resilient and stretchable closed cellular plastic material having a stretchably resilient fabriclike outer skin fixedly secured to one side thereof, said sheet being folded over upon itself with said outer skin exposed and having its abutting edges secured together along two sides thereof, the remaining edges being unsecured to permit insertion and removal of eye glasses into and from said case, the volume, density and thickness of said material being such as to enable said case to float in water with a pair of eye glasses contained therein and to cushion a pair of eye glasses contained therein against breakage in the event the case and glasses fall onto a hard object.
Claim 2
Dependent Claim
121 words
