| Abstract: |
PCT No. PCT/US86/00405 Sec. 371 Date Aug. 22, 1986 Sec. 102(e) Date Aug. 22, 1986 PCT Filed Feb. 25, 1986 PCT Pub. No. WO86/05001 PCT Pub. Date Aug. 28, 1986.An eyeglass frame (10) constructed of a single continuous hollow transparent thermoplastic tube configured to successively define a first temple piece (12), a first lens frame (14), a nose bridge portion (16), a second lens frame (18), and a second temple piece (20). The hollow inner chamber passage of the tube is filled with a colored liquid so as to impart the color of the liquid to the eyeglass frame. The free ends (24, 26) of the temple pieces (12,20) may be provided with removable plugs (28,30) so that the color of the liquid in the passage may be changed, or the free ends of the temple sections may be permanently sealed (12a) to permanently seal the liquid within the hollow passage. As a further alternative, a back piece (68) may be provided interconnecting the free ends of the temple pieces and formed of a similar tubular material so as to provide, in combination with the temple pieces, the lens frames, and the nose bridge portion, a continuous closed loop passage (70) so that the liquid in the passage may chase freely around the passage.
