| 发明名称 | Method of packaging and manufacturing a contact lens in a container | ||
| 摘要 | This invention provides a method of packaging and manufacturing a contact lens in a container, wherein the container comprises a central recess formed of a curved surface with a ring-shaped protruding portion surrounding the curved surface, the method comprising the steps of: providing the container; injecting a lens-forming monomer mixture into the central recess to form the contact lens along the curved surface of the central recess; combining the container and a hand-held section; pouring a solution into the container to immerse the contact lens in the container; and sealing the container with a lid for sealing the contact lens and the solution in the container; wherein the curved surface of the central recess has one or a plurality of continuous radii of curvature Rrecess less than a radius of curvature Rlens of the contact lens in its hydrous state. | ||

| 主权项 | 1. A method of packaging and manufacturing a contact lens in a container, wherein the container is integrally formed with a central recess formed of a curved surface and a ring-shaped protruding portion surrounding the curved surface, the method comprising the steps of: providing the container; injecting a lens-forming monomer mixture into the central recess to form the contact lens along the curved surface of the central recess while the ring-shaped protruding portion being provided to prevent the contact lens from being flung away from the container for a contact lens; combining the container and a hand-held section by engaging the container and the hand-held section in a way of rotating one of the container and the hand-held section; pouring a solution into the container to immerse the contact lens in the container; and after the steps of combining and pouring, sealing the container with a lid for sealing the contact lens and the solution in the container; wherein the curved surface of the central recess has one or a plurality of continuous radii of curvature Rrecess less than a radius of curvature Rlens of the contact lens in its hydrous state. | ||
