Description

BACKGROUND OF THE INVENTIONField of Invention

[0001] The present invention relates to a contact lens storage device.Description of the Related Art

[0002] Contact lenses are lenses that are worn directly and attached to the cornea of the eye. They can be used to correct vision, protect the eyes, and slow down the progression of myopia by reshaping the cornea. With the advent of colored contact lenses that also have visional effect functions, contact lenses have been pushed to another peak in usage.

[0003] However, since contact lenses are in direct contact with the cornea when worn, cleaning after wearing is particularly important. Traditionally, a contact lens container or a contact lens cleaning box is used to soak, clean and disinfect the contact lenses. The contact lens container is used to place the contact lenses and is also convenient for carrying the contact lenses. But some contact lenses cleansing solution generate reactive gas when the contact lenses in the solution, and a venting aperture is provided on the conventional contact lens container to discharge the reactive gas through the venting aperture.

[0004] However, the above conventional structure still has the following problems in practical application: although the venting aperture can smoothly vent, it may also cause the solution contained in the contact lens container to overflow from the venting aperture. When the solution continues to overflow, the solution in the contact lens container is insufficient to fully soak the contact lens, and the contact lens will gradually dry out and be damaged. This phenomenon is more common when the contact lens container is carried, such as when the contact lens container is placed in a bag. Therefore, it is necessary to make further improvements.

[0005] Therefore, it is desirable to provide a contact lens storage device to mitigate and / or obviate the aforementioned problems.SUMMARY OF THE INVENTION

[0017] First, please refer to FIGS. 1-4, a contact lens storage device comprises: a main body 10, a top cover 20 and a contact lens storage frame 30. The main body 10 has an opening 11 and an internal containment space 12, so that the containment space 12 is capable of accommodating the contact lens storage frame 30 and a cleaning and storage solution 50, and the opening 11 has a first joining portion 13. The top cover 20 has an outer top surface 21, an inner top surface 22 and a cover edge 23. The cover edge 23 has a second joining portion 24, and a center of the inner top surface 22 has a venting aperture 5 and a tubular member 26 which are connected to each other. An inner edge of the tubular member 26 has a first threaded section 261. The venting aperture 25 has a first aperture portion 251 penetrating the inner top surface 22 and a second aperture portion 252 penetrating the outer top surface 21. Also, the first aperture portion 251 is pinhole-shaped, and the second aperture portion 252 is larger than the first aperture portion 251, so that the venting aperture 25 forms a tapered hole that expands from the first aperture portion 251 to the second aperture portion 252. Furthermore, the contact lens storage frame 30 further comprises a main frame 31, and a storage cover 32 for placing contact lenses is pivotally assembled on both sides of the main frame 31. A pole 33 extends from a center of one end of the he main frame 31, and a second threaded section 331 is formed on an outer edge of the pole 33. The contact lens storage frame 30 is mounted on the tubular member 26 of the top cover 20 by screwing the second threaded section 331 and the first threaded section 261 together. when the contact lens storage frame 30 is placed in the containment space 12 containing the solution 50 and the opening 11 is closed by covering the top cover 20 on the main body 10, a reaction gas without surface tension generated during cleaning and soaking process discharges from a screwing gap between the first threaded section 261 and the second threaded section 331 through the venting aperture 25, and the solution 50 is blocked inside the main body 10 and the top cover 20 by the first aperture portion 251 with a small aperture due to surface tension of the liquid, so as to prevent the solution 50 from overflowing.

[0018] Moreover, the main body 10 is a transparent bottle.

[0019] In additional, the first joining portion 13 is an external thread, and the second joining portion 24 is an internal thread, so that the top cover 20 can be used with the second joining portion 24 to screw on the first joining portion 13 of the main body 10 to close the opening 11.

[0020] Furthermore, a sealing ring 14 is disposed between the main body 10 and the top cover 20.

[0021] Also, the pole 33 is enlarged with an abutment edge 34; when the pole 33 is screwed with the tubular member 26, the abutment edge 34 abuts against an end of the tubular member 26, allowing the reaction gas 51 to enter the tubular member 26 through a contact gap between the abutment edge 34 and the tubular member 26, and then be discharged outward from the venting aperture 25.

[0022] Furthermore, the abutment edge 34 is a disk

[0023] Alternatively, the abutment edge 34 is a disk, and the abutment edge 34 further has at least one venting slot 341, as shown in FIG. 6. Therefore, the reaction gas 51 is accelerated to enter the tubular member 26 from the exhaust groove 341, as shown in FIG. 7, and then discharged outward.

[0024] Optionally, the pole 33 is a short pole as shown in FIGS. 1 to 7, or a long pole as shown in FIG. 8, so that the contact lens storage frame 30 can be installed on the tubular member 26 smoothly without being limited by the length of the pole 33 and can effectively exhaust and prevent overflow.

[0025] Additionally, a reactor 40 is first placed in the containment space 12 containing the solution 50, when the reactor 40 is in contact with the solution 50, a large amount of cleaning bubbles 52 are generated, and a reaction gas 51 is produced, as shown in FIG. 4.

[0026] Moreover, the reactor 40 is a platinum reactor.

[0027] When in actual application, the contact lens is placed in the storage cover 32 of the contact lens storage frame 30 so that the contact lens can be immersed in the solution 50 in the main body 10 together with the contact lens storage frame 30. During the immersion process, the neutralization reaction between the solution 50 and the reactor 40 will generate a reaction gas 51 and a large number of cleansing bubbles 52, so that the contact lens can be cleaned through the cleansing bubbles 52, and disinfected simultaneously during the immersion. Because liquid has surface tension, but gas does not, when the reaction gas 51 is generated, the reaction gas 51 will be smoothly discharged from the first aperture portion 251 with a small diameter through the venting aperture 25, as shown in FIG. 4. On the contrary, the solution 50 with surface tension will be blocked inside the main body 10 and the top cover 20by the first aperture portion 251 with a small diameter, so as to achieve the effect of preventing the solution 50 from overflowing.

[0028] The above-mentioned anti-overflow contact lens container has the following advantages: With the threaded gap between the first threaded section 261 and the second threaded section 331 and the difference sizes of the first aperture portion 251 and the second aperture portion 252, so that only the reaction gas 51 without surface tension can be discharged, as shown in FIG. 4. Therefore, even if the contact lens container of the present invention is tilted or completely inverted, the solution 50 with surface tension can be effectively blocked in the main body 10 and the top cover 20 by the first aperture portion 251 with a small aperture, as shown in FIG. 5, so as to achieve a complete anti-overflow effect, so that the contact lens can be best preserved in the main body 10 and the top cover 20, without worrying about the problem that the solution 50 continues to overflow and causes the solution 50 to be insufficient for the contact lens to be fully soaked.

[0029] Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
