Waterproof, floatable eyeglass case

An eyeglass case formed of light-weight, thin walled plastic material comprising:

• a hollow lower part having a bottom wall, first and second opposed lower end walls extending upward from said bottom wall, a first lower side wall and an opposed second lower side wall extending upward from said bottom wall and each said lower side wall being joined to said lower end walls, said first lower end wall being longer than said second lower end wall, said first lower side wall being convex, said second lower side wall being concave, said lower part having a lower top face slanting downward from said first lower end wall to said second lower end wall,
• a hollow upper part having a top wall, first and second opposed upper end walls extending downward from said top wall, a first upper side wall and an opposed second upper side wall extending downward from said top wall and each said upper side wall being joined to said upper end walls, said first upper side wall being convex and comprising an extension of said first lower side wall, said second upper side wall being concave and comprising an extension of said second lower side wall, said first upper end wall being shorter than said second upper end wall, said upper part having an upper bottom face slanting downward from said first upper end wall to said second upper end wall to engage said lower top face when said case is closed,
• said lower first side wall curving upwardly-outwardly from said lower bottom wall, the perimeter of said lower top face being substantially larger than the perimeter of said bottom wall, and
• said upper first wall curving downwardly-outwardly from said top wall, the perimeter of said upper bottom face being substantially larger than the perimeter of said top wall,
• a first distance between said lower first and second side walls being substantially greater adjacent said lower first end wall than a second distance between said lower first and second side walls adjacent said lower second end wall to accommodate a folded pair of eyeglasses fitting closely within said hollow lower part, said first distance being substantially greater adjacent said lower top face than adjacent said lower bottom wall,
• said lower top face and said upper bottom face being substantially co-extensive,
• hinge means on said upper and lower first end walls pivotally mounting said upper and lower pans together so said case can be opened and closed, and
• latch means for latching said upper and lower parts together in closed position.
