Abstract: This invention provides a mold for forming a contact lens comprising an overflow collector, which causes the overflow reactive mixture to be accumulated, and not to spread out as it would upon the typically flat surface of a prior art mold. This invention further provides a method of preventing the formation of contaminating pieces of overflow reactive mixture comprising the step of: preventing the overflow reactive mixture from spreading out on the mold.

Abstract: This invention provides a method and a mold for improving the release of a molded ophthalmic device from a mold. The method comprises the steps of: providing a first mold half and second mold half each having opposing top surfaces at least one of which has been hollowed out to define a cavity for forming said ophthalmic device and at least said first mold half further defining a boundary for a release element, said boundary is part of said cavity, said release element comprising a ramped surface, said cavity having a corresponding ramped surface, and said release element having its widest part near the top surface of said at least said first mold half that defines said release element therein. The mold of this invention has a hollowed-out portion as part of the cavity to provide a release element to the molded ophthalmic device.

Abstract: This invention relates to a device for removing and transporting articles, such as ophthalmic lens mold sections, or packaging elements from a mold. The invention, in one embodiment includes first, second, and third assemblies; the first of which removes the articles from the molding station at a first location and transports them to a second location; the second assembly receives the articles from the first assembly and transports them to a third location, and the third assembly receives the articles from the second assembly and transports them to a fourth location. A second embodiment includes a flipper assembly disposed between the first and second assemblies, which flipper receives the articles from the first assembly and inverts them before depositing them onto the second assembly. This second embodiment is useful in conjunction with molded articles which are transported to the flipper assembly in an inverted position.
