However, many soft contact lenses are made of a material having a high water absorbency, so that germs easily propagate. For this reason, regular sterilization, which is legally required, has become indispensable, and in fact, regular users of soft contact lenses are required to disinfect daily.

る。[0003] In this disinfection, a soft contact lens is first washed, then stored in a lens case containing a preservative solution, and the lens case is disinfected by boiling with a contact lens boiling disinfecting device (hereinafter referred to as a boiling device). The method is widespread. The structure of this boiling device will be described with reference to the drawings of the embodiments described later. As shown in FIG. 1, a palm-sized boiling device 1 is opened, and when its upper lid 2 is opened, a shallow bottomed storage container opened upward. What is part 3 is a typical structure. The storage section 3 includes a heating plate 5 at the bottom and a peripheral wall 7 formed by a peripheral edge of an opening formed above a main body case of the boiler. Then, the lens case 20 is placed on the upper surface of the heating plate 5 serving as the bottom of the storage unit 3 and is set for several tens minutes to
It has been disinfected by boiling for more than an hour. The joint 9 between the heating plate 5 and the peripheral wall 7 is made densely water-tight, so that even if water or a preservative solution drips into the storage part for some reason, it does not enter the boiling device. ing.

ショック、及び、汚れに備えてある。[0004] Since many of these heating plates are directly brought into contact with an electric heater to heat them, in such a case, they must be insulators, and therefore, heat-resistant plastic plates or ceramic plates are used. A heating plate made of a heat-resistant plastic plate is widely used because of its excellent cost. However, when boiling, the preservation solution may leak due to the looseness of the lid of the lens case or cracks in the lens case itself, and the leaked solution hydrolyzes the plastic, which has the disadvantage of cracking. In this regard, ceramic plates are excellent in chemical strength and high in thermal conductivity, so they are suitable for heating plates, and ceramic plates made of alumina or the like are often used. However, as mentioned above, the preservation solution may leak when boiling, and when the preservation solution falls on the high-temperature heating plate, the ceramic heating plate
May break due to heat shock. In addition, the liquid evaporates without cracking, and often burns with dirt due to aging. Therefore, as consideration for such a thing,
In order to protect the surface of the heating plate, a stainless steel thin plate is often superimposed on the upper surface of the heating plate to prevent heat shock and contamination caused by the leaked preservative solution.

No. On the other hand, the ceramic itself can be selected from materials resistant to heat shock, but these tend to be expensive.
Still further, there is a ceramic plate which is provided with a heat-resistant plastic thin plate overlaid thereon to protect the surface. However, there is a problem that thermal conductivity is poor and sufficient heating cannot be obtained.

た問題が起き始めている。[0006] In recent years, various improvements have been made to the used preservatives, and the types of the preservatives have also become diverse. However, among them, those which corrode even materials having high touch resistance such as stainless steel have become widespread, and this has caused an unprecedented problem of corrosion of stainless steel.

ートショックも小さくなるのである。According to the present invention, a water repellent treatment is applied to the upper surface of a ceramic plate to be used as a heating plate. In this way, even if the storage solution leaks from the lens case, the upper surface of the heating plate becomes water-repellent, so that it is repelled even if the storage solution leaks out, so that the contact surface of the heating plate with the storage solution is minute. The heat shock can be reduced accordingly. Specifically, as shown in FIG. 3 (a), the leaked preservative solution is repelled to form a polka dot, and conventionally, as shown in FIG. 3 (b), comes into contact with the heating plate in a state close to a hemisphere. The contact surface is smaller than what was done, and the heat shock is also smaller.

ートショックが小さくなる。Also, due to the water-repellent treatment, the leaked storage solution does not adhere to one place of the heating plate and stops, but the repelled polka-dot liquid runs around the heating plate in a manner dancing. Therefore, also in this point, the heat shock is much smaller than that of the conventional heating plate in which the preservation solution wets one portion of the heating plate and stops.

く、以上の各種性質が長く安定して維持できる。In the present invention, such a water-repellent treatment is performed by applying a fluororesin. This is because excellent water repellency can be obtained. As the fluororesin, polytetrafluoroethylene, polychlorotrifluoroethylene, vinyl fluoride, ethylene trifluoride, vinylidene fluoride, propylene hexafluoride, or the like can be used. In addition, when such a fluororesin is applied, chemical durability can be obtained on the upper surface of the heating plate, and high corrosion resistance can be obtained even for various preservation liquids. In addition, if it is a fluororesin, it has excellent insulation properties.
It is suitable for use near an electric heater. Furthermore, since the fluororesin does not show thermoplasticity, it is resistant to high temperatures, and the above various properties can be maintained stably for a long time.

Has a dense water. A ceramic plate 10 made of alumina is used for the heating plate 5, and a polytetrafluoroethylene (for example, Teflon (registered trademark) or the like) is applied to the entire surface of one side thereof to form a fluororesin layer 11. is there. Then, this fluororesin layer 11 is
The main body case 6 is joined to the lower end of the peripheral wall 7 formed by the peripheral edge of the opening to form the storage section 3. Further, the heating plate 5 is an electric heater 12 contacting the lower surface thereof,
It is being heated.

According to this, even if the lid 21 of the lens case 20 is loose or the storage solution leaks during boiling, the storage solution leaked to the heating plate 5 is repelled by the water repellent effect, and as a result, a polka dot is formed. Therefore, the contact surface with the heating plate 5 becomes smaller than before. In addition, since the heating plate 5 has a high temperature, the polka dot-shaped preservative liquid runs repeatedly over small bumps, and does not stop at one place until it evaporates and disappears. There is no sudden drop in temperature.

The contact lens is placed in a lens case containing a preservative solution, and the lens case is placed on the heating plate for disinfection by boiling. Sometimes a lens case
If the preservative solution leaks and falls on the upper surface of the heating plate,
Of the preservative solution that has leaked out,
It is repelled by repetition and water repellency . " For this reason, even if the storage solution leaks from the lens case due to an unexpected situation, the storage plate repels the storage solution to form a polka dot due to the water repellent effect of the heating plate, thereby reducing the contact surface between the storage solution and the heating plate. In addition, since the repelled polka-dot-shaped preservative runs around without stopping at one place at a high temperature of the heating plate, the heat shock becomes extremely small, and therefore, the cracking of the heating plate due to the heat shock can be prevented.

きる。According to a second aspect of the present invention, in the first aspect of the invention, it is characterized in that the water-repellent treatment is performed by applying a fluororesin. Therefore, the water repellent effect according to claim 1 can be sufficiently obtained, and even when the dirt is heated, it does not burn and is excellent in dirt prevention. Furthermore, since high corrosion resistance is obtained, there is no corrosion and no formation of corrosion products. Therefore, any storage solution can be used without having to worry about corroding the heating plate. In addition, the heating plate is generally required to maintain the watertightness of the electric circuit portion built in the main body case together with the main body case of the disinfecting device. However, according to the present invention, corrosion occurs at a joint portion with the main body case. Therefore, high watertightness can be maintained. In addition, even if the use at a high temperature is continued for many years, the various characteristics according to the first and second aspects do not deteriorate, and excellent characteristics can be maintained for a long time.
