MOLD FOR FORMING A CONTACT LENS AND METHOD OF PREVENTING FORMATION OF SMALL STRANDS OF CONTACT LENS MATERIAL DURING CONTACT LENS MANUFACTURE
This invention provides a mold (21) for forming a contact lens including an overflow collector (38), which causes the overflow reactive mixture (23) to be accumulated, and not to spread out as it would upon the typically flat surface of a prior art mold. The invention further provides a method of pr...

| description | This invention provides a mold (21) for forming a contact lens including an overflow collector (38), which causes the overflow reactive mixture (23) to be accumulated, and not to spread out as it would upon the typically flat surface of a prior art mold. The invention further provides a method of preventing the formation of contaminating pieces of overflow reactive mixture by preventing the overflow reactive mixture from spreading out on the mold (21).
La présente invention concerne un moule (21) de formage de lentille de contact équipé d'un collecteur de débordement (38) provoquant l'accumulation du mélange réactif de débordement (23) pour l'empêcher de s'écouler à l'extérieur du moule comme cela se produit généralement sur la surface plate du moule selon l'état antérieur de la technique. L'invention concerne également un procédé qui, pour empêcher la formation de morceaux contaminants de mélange réactif de débordement, empêche ce dernier de s'écouler hors du moule (21). |
