Abstract
A molded plastic resin contact lens marking fixture is provided having a cup-like base with an upstanding internal pedestal having an upper surface which is a segment of a sphere for receiving a contact lens. The axis of the segment is tipped from the vertical so that a peripheral portion of the lens is in uppermost position. A lid is received over the base and includes a masking area which is resiliently urged toward the uppermost portion of the pedestal. Perforations are provided in the masking area, and a dye well is provided above the masking area so that dye in the well will be transmitted through the perforations to mark a contact lens near the periphery thereof.
Claims16
A contact lens marking fixture comprising a cup-like base having a bottom and an upstanding sidewall defining an open upper end, a pedestal upstanding from said bottom and spaced inwardly from said sidewall, said pedestal having an upper surface adapted to receive a contact lens for marking, and a lid received over said open upper end and supported by said sidewall, said lid having a masking area adapted to engage a contact lens on said pedestal upper surface and having perforation means therein for admitting dye to the surface of a contact lens, said lid having a dye well disposed on an exterior surface thereof and above said masking area, said dye well communicating with said perforation means for receiving dye and applying said dye to said contact lens through said perforation means.
A contact lens marking fixture comprising a cup-like base having a bottom and an upstanding sidewall defining an open upper end, a pedestal upstanding from said bottom and spaced inwardly from said sidewall, said pedestal having an upper surface adapted to receive a contact lens for marking, and a lid received over said open upper end and supported by said sidewall, said lid having a masking area adapted to engage a contact lens on said pedestal upper surface and having perforation means therein for admitting dye to the surface of a contact lens, said lid having a dye well disposed above said masking area for receiving dye to be applied to said contact lens, said pedestal upper surface comprising a segment of a sphere, the centrally located axis of said segment being tipped from vertical and the uppermost portion thereof being eccentric relative to said base, said dye well having said masking area similarly being eccentric and aligned with the uppermost portion of said pedestal segment of a sphere.
A contact lens marking fixture comprising:
- a cup-like base having a bottom and an upstanding sidewall:
- a pedestal upstanding from said bottom and spaced inwardly from said sidewall, said pedestal having an upper surface adapted to receive a contact lens for marking;
- and masking means carried by said base and including a masking area said masking means being positionable over said pedestal with the masking area adapted to engage a contact lens on said pedestal upper surface, and said masking area having perforation means therein for admitting dye to the surface of a contact lens, and a dye well disposed above said masking area on the side of said masking means opposite that engageable with said lens, said dye well for receiving a quantity of dye and being in communication with said perforation means to apply dye to said contact lens.
A contact lens marking fixture comprising:
- a base;
- a pedestal upstanding from said base;
- said pedestal having an upper surface adapted to receive a contact lens for marking;
- and masking means carried by said base and including a masking area said masking means being positionable over said pedestal with the masking area adapted to engage a contact lens on said pedestal upper surface, and said masking area having perforation means therein for admitting dye to the surface of a contact lens, said pedestal upper surface comprising a segment of a sphere, the centrally located axis of said segment being tipped from vertical and the uppermost portion thereof being eccentric relative to said base, said dye well having said masking area similarly being eccentric and aligned with the uppermost portion of said pedestal segment of a sphere.
