Description

Technical Field

[0001] This utility model relates to a contact lens cleaning container, specifically a breathable contact lens container that prevents the leakage of cleaning solution. Background Technology

[0002] Contact lenses are lenses that are worn directly on the cornea of ​​the eye. They can be used to correct vision, protect the eyes, and slow down the progression of myopia (orthokeratology lenses). With the advent of colored contact lenses (pupil enlargement lenses) that also have a makeup function, the use of contact lenses has reached another peak.

[0003] Since contact lenses come into direct contact with the cornea during wear, post-wear cleaning is extremely important. Traditionally, the lenses are washed manually by touching to remove surface proteins, followed by soaking and disinfecting them in a contact lens cleaning case. However, most cleaning cases currently available lack a breathable structure. During the soaking process, the maintenance solution or cleaning solution generates reactive gases. These gases cannot escape, creating a high-pressure environment inside the cleaning case. This causes the maintenance solution or cleaning solution to be pushed by the reactive gases into the gap between the case body and the lid, resulting in leakage. This causes inconvenience and raises safety concerns.

[0004] In view of this, based on the author's many years of experience in manufacturing, developing and designing related products, and after detailed design and careful evaluation for the above objectives, the author has finally come up with this utility model that is indeed practical. Utility Model Content

[0005] The technical problem this utility model aims to solve is to address the aforementioned deficiencies in the existing technology by providing an anti-overflow contact lens container, which includes a box body, a storage rack, and a lid. The box body has a chamber for containing contact lens care solution, the storage rack is housed in the chamber, and the top of the storage rack has a combined stud. The lid is fitted onto the top of the box body, further sealing the box body. A combined screw hole is provided at the center of the bottom of the lid, which is screwed into the combined stud of the storage rack. The combined stud and the combined screw hole are not completely tightly fitted, leaving a venting gap. A venting pinhole is provided through the center of the top of the box body, and the venting pinhole communicates with the combined screw hole. Thus, the venting gap and the venting pinhole are used to allow the reaction gases generated during the care solution's care and cleaning of contact lenses to be discharged. The liquid has a strong surface tension, which is further restricted by the venting pinhole to prevent the care solution from overflowing.

[0006] Preferably, the top of the box body has an opening communicating with the chamber, the outer diameter surface of the opening is provided with an external thread section, the bottom outer edge of the box cover is provided with an annular groove, the inner diameter surface of the annular groove is provided with an internal thread section that is screwed into the external thread section of the opening, and a water-stop washer is further embedded inside the annular groove, the water-stop washer tightly abutting against the edge of the opening when the box cover is attached to the box body.

[0007] Preferably, the stud of the storage rack is a short stud, the length of which is less than the depth of the screw hole, so that there is an air chamber between the top of the stud and the inner wall of the screw hole.

[0008] Preferably, the stud of the storage rack is a long stud, the length of which is similar to the depth of the screw hole, so that the top of the stud is close to the inner wall of the screw hole but not in contact with it.

[0009] Preferably, the top of the storage rack has a support platform, the combined stud is formed at the center of the support platform, and the surface of the support platform has at least one venting groove on each side of the combined stud.

[0010] Preferably, the diameter of the venting pinhole of the box cover gradually decreases from top to bottom to form a conical hole.

[0011] Compared with the prior art, the contact lens container of this utility model has a breathable effect through the venting gap and venting pinhole. During the contact lens cleaning process, the reactive gas generated by the maintenance solution can be discharged through the venting gap and venting pinhole, avoiding the concern that the maintenance solution may deteriorate or become contaminated after the contact lenses are stored for a long time, keeping the lenses clean, and thus improving the safety of wearing contact lenses.

[0012] In addition, due to the surface tension of the liquid, and the fact that the reactive gas will preferentially be discharged through the venting gap and the venting pinhole, the contact lens solution cannot enter the venting gap or pass through the venting pinhole without additional pressure, thus further preventing the solution from overflowing.

[0038] To further understand and recognize the purpose, features, and effects of this utility model, the following is a detailed description in conjunction with the accompanying drawings:

[0039] First, please let Figures 1 to 5As shown, a spill-proof contact lens container includes a housing 10, a storage rack 20, and a lid 30. The housing 10... The case 10 has a chamber 11 for holding contact lens care solution. A storage rack 20 is housed in the chamber 11 and has a combination stud 21 at its top. A case cover 30 is fitted on top of the case 10 to further seal the case 10. A combination screw hole 31 is provided at the center of the bottom of the case cover 30 and is screwed into the combination stud 21 of the storage rack 20. The combination stud 21 and the combination screw hole 31 are not completely tightly fitted, with a venting gap 32. A venting pinhole 33 is provided at the center of the top of the case 30 and is connected to the combination screw hole 31. The venting gap 32 and the venting pinhole 33 are used to allow the reaction gases generated when the care solution is used to care for and clean the contact lenses to be discharged. Because the care solution and other liquids have surface tension, they are not only difficult to enter the venting gap 32 between the combination stud 21 and the combination screw hole 31, but are also restricted by the venting pinhole 33 to prevent the care solution from overflowing.

[0040] Further explanation: The top of the box body 10 has an opening 12 communicating with the chamber 11. The outer diameter surface of the opening 12 has an external thread section 121. The bottom outer edge of the box cover 30 has an annular groove 34. The inner diameter surface of the annular groove 34 has an internal thread section 341 that screws into the external thread section 121 of the opening 12. A water-stop washer 35 is further embedded inside the annular groove 34. The water-stop washer 35 is connected to the box cover 30 and the box body 11. At 0, it closely abuts against the edge of the opening 12 to ensure the sealing state of the box body 10; furthermore, the top of the storage rack 20 has an abutment platform 22, and the combined stud 21 is formed at the center of the abutment platform 22. In this embodiment, the combined stud 21 is a short stud, and the length of the combined stud 21 is less than the depth of the combined screw hole 31, so that there is an air chamber 36 between the top of the combined stud 21 and the inner wall of the combined screw hole 31. The diameter of the exhaust pin hole 33 of the box cover 30 gradually shrinks from top to bottom to form a conical long hole.

[0041] A preferred embodiment of its structure, please refer to... Figure 6 As shown, the combined stud 21 of the storage rack 20 is a long stud, and the length of the combined stud 21 is close to the depth of the combined screw hole 31, so that the top of the combined stud 21 is close to the inner wall of the combined screw hole 31 but does not contact it.

[0042] Another preferred embodiment of its structure is described below. Figure 7 , 8As shown, the surface of the abutment platform 22 of the storage rack 20 is provided with at least one vent groove 221 on each side of the combined stud 21. In this embodiment, three parallel vent grooves 221 are provided on each side of the combined stud 21, and the outer ends of the vent grooves 221 all penetrate the outer edge of the abutment platform 22. Accordingly, when the edge of the combined screw hole 31 of the cover 30 is abutted against the abutment platform 22, the vent grooves 221 form a channel between the abutment platform 22 and the edge of the combined screw hole 31 to allow the reaction gas generated by the maintenance liquid to pass through, further ensuring the discharge of the reaction gas.

[0043] The following benefits can be obtained through the structure of the above specific embodiments: The contact lens container of this utility model has a breathable effect through the venting gap 32 and the venting pinhole 33. During the contact lens cleaning process, the reactive gas generated by the maintenance solution can be discharged through the venting gap 32 and the venting pinhole 33, avoiding the concern that the maintenance solution may deteriorate or become contaminated after the contact lenses are stored for a long time, keeping the lenses clean, and thus improving the safety of wearing contact lenses.

[0044] In addition, due to the surface tension of the liquid, and the fact that the reactive gas will preferentially be discharged through the venting gap 32 and the venting pinhole 33, the contact lens care solution cannot enter the venting gap 32 and pass through the venting pinhole 33 without additional pressure, further preventing the care solution from overflowing.

[0045] The above description is only a preferred embodiment of this utility model and should not be construed as limiting the scope of this utility model; that is, all equivalent changes and modifications made in accordance with the scope of the patent application of this utility model should still fall within the scope of this utility model patent.
