Field of the Invention The present invention relates to a method of packaging a contact lens, and more particularly to a method of packaging a disposable contact lens. [Prior Art] The placement of hydrophilic contact lenses in a disinfecting solution is a well-known technique for contact lenses, particularly the so-called blister packaging, in which medical personnel store and dispense hydrophilic contact lenses, or for wearing them. Used by the user of the mirror. Such hydrophilic contact lenses are discarded after a period of use and are all made using suitable hydrophilic polymerization. As a result, contact lens manufacturers used bottled glass bottles to infiltrate saline in the early days and soaked hydrophilic contact lenses as containers for the delivery of contact lenses. Each glass bottle uses a enamel stopper and a metal envelope as a safety cap to form a double bottle. When the wearer wants to take out the contact lens from the bottle, the metal envelope is needed, and then the bottle stopper is pulled out, and the plastic clip-on glasses are used to clip out or pour it out. Thus, it is very complicated to take out the contact lens. Due to the transparent nature of the contact lens, the use of contact lenses that are easily immersed in saline solution by the naked eye is clamped and removed. In recent years, hydrophilic contact lenses have been made available due to the development of a blister package for placing contact lenses. Simple and inexpensive storage and shipping, another advantage of the box is that it allows the doctor or wearer to easily remove the contact lens from the box. 326\Patent Specification (Replenishment)\92-05\Essential Optics-924509 5 Regarding the manufacturing industry, it is used for invisible eyes or material filling and other storage and plugging, the cover of the knot will be removed first. 〇Packaging method to treat people 1278412 Since disposable contact lenses are usually used for a short period of time, such as days or weeks, often replacing disposable contact lenses will make them use a large amount, and relatively, for packaging abandonment The number of use of the contact lens case is also large; and the use of the material for the manufacture of disposable contact lenses by the molding method is also increased. Therefore, in order to reduce the cost of packaging materials (such as packaging boxes) and manufacturing materials, it is considered to use a male mold (Male Mold) or a female mold (Female Mold) for manufacturing disposable contact lenses as a package, such as the US Patent Publication No. US 5,4 0 7,〇6 2 patent case. In the above patent, the monomer mixture (M〇n〇mer Mix) injected into the master mold is pressed into the male mold by the male mold, and after plasticizing to form the contact lens, the invisible shape attached to the male mold or the female mold is required. The glasses are removed (i.e., the mold release procedure), and the contact lens is immersed in a package portion of a male mold or a master mold filled with a saline solution, and then packaged. In this prior art, the process of the disposable contact lens from the manufacturing to the packaging, the demolding process is a more complicated procedure, increasing the complexity of the entire process; in addition, the pressure of the tea-type contact lens from the male or female mold The joint is removed and placed in the packaging section of the male or female mold. Such a design will increase the complexity of the construction of the male or female mold, and also the material used for the male or female mold. SUMMARY OF THE INVENTION The packaging of the mirror can reduce demolding and save material. SUMMARY OF THE INVENTION It is an object of the present invention to provide a disposable invisible eye method which allows a process for manufacturing a disposable contact lens from manufacture to packaging, and which can simplify the construction of a male or female mold, and the present invention The mixed surface is pressed into one of the concave invisible concave surfaces of the female injecting mold, and is pressed into the packaging mother mold of the glasses, and the convex method of the male mold is firstly convex and convex The female mold concave 326\patent specification (supplement)\92-〇5 备华光学_924509 6 1278412, and the monomer mixture between the sides is plasticized to form a contact lens packaging method features first, separate a male mold and a female mold, the plasticized contact lens is attached to the concave surface of the female mold; then, an aqueous saline solution is injected into the female mold to which the contact lens is attached, so that the contact lens expands and absorbs the moisture after being absorbed from the concave surface, and The outer edge of the expanded contact lens is raised above the concave surface to cover the invisible edge; and the flange of the female mold is sealed with the sealing glasses and the saline solution in the mother mold. [Embodiment] FIG. 1 is a cross-sectional view of a male mold of the present invention, and FIG. 2 is a cross-sectional view of a mother mold of the present invention. A disposable contact lens is manufactured by Cast , ο ο 1 ding, wherein a convex surface 1 of a male mold 10 made of polypropylene can form a concave surface of a contact lens, and a mother material made of polypropylene. The concave surface 16 of the core 14 can form a convex surface of the contact lens. When the male mold 10 and the female mold 14 are pressed together, the horizontal flange 11 of the male mold 10 is fitted to the female mold. The vertical flange 15 of 1 4 can make the male mold 10 and the female mold 14 not separate from each other during the process of pressing and plasticizing, as shown in Fig. 3 is a sectional view of the male mold and the female mold of the present invention. Shown. In Fig. 3, the monomer mixture 18 injected between the convex surface 1 2 of the male mold 10 and the concave surface 16 of the female mold 14 can form a contact lens after the plasticizing process, and the vertical plane of the male mold 10 A gap is formed between the 19 and the concave surface 16 of the female mold 14 to facilitate the detachment of the male mold 10 from the female mold 14. After the plasticizing process, the male mold 10 and the female mold 14 are detached, and the prepared contact lens 20 is attached to the concave surface 16 of the female mold 14 as shown in FIG. The contact lens is attached to the parent mold 14 as shown in the cross-sectional view. 5 is a cross-sectional view of FIG. 4 filled with a saline solution and packaged, and FIG. 6 is a cross-sectional view of the invisible eye 326 of FIG. 5 \ patent specification (supplement) \ 92-05 \ elite optical - 924509 1278412 mirror expansion. Figure 7 is a flow chart of the present invention. For convenience of the description of Figure 7, reference may be made to Figures 1 to 6. In Fig. 7, a monomer mixture 18 is injected into a master mold 14 having a concave surface 16 (step S70), and the convex surface 1 2 of the male mold 10 is pressed into the concave surface 16 of the female mold 14. To pressurize the monomer mixture 18 therebetween (step S71); then, the monomer mixture 18 pressed between the convex surface 12 of the male mold 10 and the concave surface 16 of the female mold 14 is subjected to high temperature plasticization. Or forming a contact lens 20 by ultraviolet light (step S 7 2 ), separating the male mold 10 and the female mold 14 to attach the plasticized contact lens 20 to the concave surface 16 of the female mold 14 (steps) S 7 3 ); Next, the saline solution 22 is injected into the master mold 1 4 to which the contact lens 20 is attached (step S 7 4 ), and a metal foil 2 4 is used (the material of the metal foil 24 is used as a seal) And sealing the flange 15 of the female mold 14 with any material that withstands high temperature and high pressure sterilization, so as to enclose the contact lens 20 and the saline solution 2 2 in the master mold 14 (step S 7 5 ); The encapsulated contact lens 20 is subjected to high temperature and high pressure sterilization (step S76) to enable the user to wear the disposable contact lens 20 without infection. Since the contact lens 20, which is a hydrophilic polymeric material, absorbs the saline solution 2 2, the contact lens 20 will be inflated to escape the concave surface 16 and the outer edge of the expanded contact lens 20 is raised above the concave surface 16. The upper edge facilitates the user to remove the contact lens 20 from the inner mold 1 4 . The invention has the advantages that the disposable contact lens is plasticized into a contact lens attached to the concave surface of the master mold from the manufacturing to the packaging process, and the saline solution is directly injected into the mother mold without taking out the contact lens from the master mold. And encapsulation, which can reduce the demolding process, increase the speed of the entire process, and use the simple construction of the male and female molds, can save the material required for the manufacture of disposable contact lenses 326\patent specification (supplement ) \92-05\Essence Optics - 924509 8 1278412 material, can also save the materials needed to package disposable contact lenses.
