Description

Contact lens box

Technical Field

The present invention relates to a contact lens case, and more particularly, to a contact lens case which can eliminate foam generated from hydrogen peroxide and is inexpensive.

Background

A contact lens or a contact lens is a lens which is worn on the cornea of an eyeball to correct vision or protect the eye. Proper wear and routine care of contact lenses is important to the health of the eye. The contact lenses are continuously attached with deposits such as protein, grease, bacteria and the like in the using process, and need to be taken off and cleaned by a surfactant solution with a washing function after being worn for a certain time. Picking contact lenses by hand and cleaning by hand further exacerbates germ contamination, and therefore, after washing, the lenses must be sterilized by immersion in a sterilizing solution. The contact lens multifunctional care solution integrating cleaning and sterilization is available in the market, but the bactericides in the products can be greatly adsorbed by the contact lenses, so that the sterilization capability is insufficient, and the eye discomfort caused by stimulation of the bactericides to the eyes is caused. In recent years, research shows that the hydrogen peroxide (commonly called hydrogen peroxide, H) contains about 3 percent of hydrogen peroxide₂O₂) The nursing liquid has strong sterilization capability and can not be adsorbed by the contact lenses, and the eyes are safe and comfortable after the nursing liquid is used.

However, hydrogen peroxide can cause severe burns to the eye if it remains on the lens, and it is necessary to remove the hydrogen peroxide prior to wearing the contact lens. Two currently popular ways of neutralizing hydrogen peroxide in the market are to put hydrogen peroxide solution into a contact lens case, then put neutralizing tablets into the case, and stand for six hours; or directly arranging a platinum ring capable of neutralizing hydrogen peroxide in the contact lens box, pouring hydrogen peroxide solution into the contact lens box, and standing for six hours. The disinfection and removal of hydrogen peroxide from the hydrogen peroxide solution are generally performed simultaneously. The decomposition of hydrogen peroxide into oxygen and water begins from the moment the contact lens is placed in the hydrogen peroxide solution. After six hours, the sterilization is finished and the hydrogen peroxide is completely neutralized. Regardless of the neutralization method, when the hydrogen peroxide reacts to form oxygen, a large amount of bubbles are formed in the case, especially within one hour from the beginning of the reaction. Because the hydrogen peroxide solution also comprises a scale inhibitor, a chelating agent, a water softener and other components, the foam generated in most cases cannot be broken by oneself rapidly, if the spectacle case is not sealed, the hydrogen peroxide solution can flow out of the spectacle case along the vent hole, so that the cleaning and disinfecting efficiency of the lenses is reduced, and the hydrogen peroxide solution with strong oxidizing property and corrosiveness can flow out of the spectacle case body to pollute and destroy the place where the spectacle case is placed. Of course, it is not practical to place the lens in a completely sealed case, and the pressure in the case may be abnormally increased due to the generation of a large amount of oxygen, which may cause damage to the lens or even the case.

In the prior art (CN202909154U), a contact lens case (see fig. 1-3) suitable for hydrogen peroxide solution is roughly structured as follows:

comprises a box cover 1 and a cup body 2 which are matched with each other to form a closed box body; the cup body 2 is cylindrical, scale marks are arranged on the side wall of the cup body 2, and the box cover 1 comprises a cover and a plate-shaped support 4 which is fixed on the inner surface of the cover and extends into the inner cavity of the cup body 2; the box cover 1 consists of an inner layer wall, an outer layer wall and a side wall, wherein the inner layer wall is provided with 2 through holes, and the outer layer wall is provided with 1 through hole so as to reduce the air pressure in the closed box body; the tail end of the plate-shaped bracket 4 close to the bottom of the cup body 2 is movably connected with an annular body 5 with a platinum layer plated on the surface; the outer wall of the annular body 5 is provided with a plurality of strip-shaped bulges vertical to the bottom surface of the cup body so as to enlarge the area of the platinum layer; the middle parts of two side surfaces of the plate-shaped bracket 4 protrude outwards to form two symmetrical bulges 6 of which the outer surfaces are matched with the concave surfaces of the contact lenses, and a plurality of through holes which are arranged in a radial shape are arranged on the plate-shaped bracket 4 around the bulges 6; the protrusions 6 can be used to support the concave surface of a contact lens; the outer side of each bump 6 is provided with an openable mesh enclosure 7, the concave surface of each mesh enclosure 7 is matched with the convex surface of the contact lens, the mesh enclosure 7 and the bumps 6 form a cavity matched with the contact lens, and one end of each mesh enclosure 7 close to the cover 3 is connected with the plate-shaped support 4 through a shaft pin structure; the contact lenses are taken and placed when the mesh enclosure 7 is opened, and the contact lenses are fixed in the cavity when the mesh enclosure 7 is closed.

This is also the most common contact lens case suitable for hydrogen peroxide solutions currently on the market (cf. the great wall of the small wall of the great wall of. Due to the cost, the contact lens box can only complete the basic functions of sterilization and containing of the contact lenses, and has no great difference from other hydrogen peroxide lens boxes in the basic structure, but has different shapes. Although it is mentioned in the description that the volume of the cartridge can be increased to await the elimination of foam, this is after all a passive method, with no active intervention on the foam itself. In fact, the foam removing effect of the contact lens box is not obvious, because the foam formed by the hydrogen peroxide care solution is mixed with various catalysts, stabilizers and water-retaining agents, the foam is not easy to break in the air, the foam can easily run to the outside of the box body along with overflowed gas, and through tests, even if the hydrogen peroxide care solution is added to a certain distance below a scale line, the foam also can flow out from a box body vent hole. This condition continues until the contact lens case is used for about one month, and the hydrogen peroxide solution is used up after one month to one and a half months, according to the experience of the inventor, the hydrogen peroxide solution lens case can not be used any more. Therefore, it is preferable to have active intervention in the foam so that it does not flow out from the beginning.

In order to solve the problems, the spectacle case which is low in cost, strong in universality, easy to clean and capable of obviously improving the foam removing performance of the conventional hydrogen peroxide contact lens case is urgently needed in the market.

In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and the specific embodiments of the specification, and it should be understood that the embodiments and specific features of the embodiments of the present invention are detailed descriptions of the technical solutions of the present application, and are not limited to the technical solutions of the present application, and the technical features of the embodiments and examples of the present invention may be combined with each other without conflict.

For convenience of explanation, in the specification, oxygen generated by the reaction of the hydrogen peroxide solution is referred to as bubbles when the oxygen is below the surface of the solution, and once the bubbles rise above the surface of the solution, a layer of the solution is wrapped, and a plurality of small bubbles are gathered together and referred to as foam.

Referring to fig. 4 to 8, the contact lens case of the present invention comprises a case cover 1 and a cup body 2, wherein a plate-shaped holder 4 is fixed on the inner surface of the case cover 1 and extends into the inner cavity of the cup body 2; the middle parts of two side surfaces of the plate-shaped bracket 4 protrude outwards to form bulges 6 matched with the contact lens; the outer side of each bulge 6 is provided with a mesh enclosure 7 which can be opened and closed, and the mesh enclosure 7 and the bulges 6 form a cavity 3 for placing contact lenses; the upper end connecting part 8 connected with the mesh enclosure 7 is rotatably arranged on the plate-shaped support 4, the plate-shaped support 4 between the upper surface of the mesh enclosure 7 and the lower surface of the box cover 1 is sleeved with a foam removing net 9 with a plurality of through holes 11, a matching hole 10 is arranged in the middle of the foam removing net 9, and the foam removing net 9 can move up and down relative to the plate-shaped support 4 through the matching hole 10.

The basic structure of the contact lens case of the present invention is substantially identical to that of prior art binocular water contact lens cases. As shown in fig. 4-6, the lens is accommodated in a cavity 3 defined by a mesh 7 and a plate-mounted bracket 4, the plate-mounted bracket 4 is vertically disposed and the upper end thereof is fixed to the box cover 1, and the plate-mounted bracket 4 between the lower bottom surface of the box cover 1 and the lens-accommodating mesh 7 has a certain length. The structure is characterized in that the diameter of the mesh enclosure 7 is large when viewed from the front and is only slightly smaller than the cup body 2, the mesh enclosure 7 protrudes outwards when viewed from the side, and the outward protruding size is large; above the mesh 7 and the lower surface of the lid 1, there is a portion having a reduced projected area, which includes the upper end connecting portion 8 and a portion of the plate bracket 4. Generally, the upper part of the part is the lower surface of the box cover 1. There are sometimes structures such as coupling seats, coupling slots or the like for coupling the lid 1 and the panel-mounted bracket 4, but these structures generally have a relatively small projected area and are significantly smaller than the projected area of the upper end coupling portion 8 and the corresponding portion of the panel-mounted bracket 4, without affecting the movement of the bubble removing structure.

In the basic structure of the hydrogen peroxide glasses box, a foam removing net 9 with a plurality of through holes 11 is sleeved on the plate-shaped support 4 between the mesh 7 and the lower surface of the box cover 1, a matching hole 10 is formed in the middle of the foam removing net 9, and the area of the matching hole 10 is large enough, so that the foam removing net 9 can be sleeved in the upper end connecting part 8 and can move to be in contact with the lower surface of the box cover 1. Thus, the bubble trap net 9 is moved up and down with respect to the plate bracket 4 through the fitting hole 10. And because the area and the shape of the matching hole 10 are designed specifically, the matching hole can be completely free from the influence of the upper end connecting part 8 and the corresponding part of the plate-mounted bracket 4. That is, the bubble trap net 9 of the present invention can maximally complete the movement along the plate-mounted case 4 without changing the basic structure of the conventional glasses case.

The present invention is a prior art contribution to the art, and is centered on the blister pack 9. However, the defoaming net 9 of the present invention does not act alone, but rather is put into a hydrogen peroxide contact lens case of the prior art to act in cooperation with the prior art structure, i.e., the defoaming net 9 of the present invention is sleeved on the plate-mounted holder 4 above the mesh 7. Under this kind of structure, when the spectacle case normally placed, bubble removal net 9 itself had certain weight, by means of mating holes 10 can be free embolia upper end connecting portion 8 completely, the lower surface that removes bubble net 9 basically with the upper surface parallel and level of screen panel 7, that is to say, remove bubble net 9 and can block in the top of screen panel 7.

In actual operation, the spectacle case is opened, hydrogen peroxide solution nursing liquid is poured into the cup body 2 along the scale lines, the contact lens is placed into the cavity 3, the mesh enclosure 7 is covered, the box cover 1 and the cup body 2 are screwed, at the moment, the hydrogen peroxide solution nursing liquid can quickly react under the catalysis of the platinum layer of the annular body 5 to release a large amount of oxygen bubbles, the oxygen bubbles rise upwards to reach the liquid level of the nursing liquid (the liquid level is approximately positioned near the upper surface of the mesh enclosure 7 and exceeds the cavity 3), a large amount of bubbles are continuously generated along with the continuous reaction of the hydrogen peroxide solution, and because the components of the nursing liquid are complex, a large amount of foams can be formed on the liquid level, and the foams below can continuously push the foams above and finally flow towards the vent hole 12. At this time, the glasses case in the prior art can be automatically extinguished by foam without active intervention, and the foam overflows out of the glasses case under most conditions.

The treatment of the foam containing the solution in the hydrogen peroxide contact lens box has two difficult technical problems, namely firstly, the foam is generated in a relatively narrow space which is relatively closed, even if an air hole exists, the space has a certain difference with the ambient air exchange capacity of an open container, the upper layer foam is pushed by the lower layer foam which is continuously generated to slowly move towards a box cover, and the lower layer foam continuously provides upward kinetic energy for the upper layer foam after rising out of the liquid level of the care solution, so that the upper layer foam is continuously pushed and lifted; secondly, the structure and the volume of the basic parts of the prior contact lens case are basically fixed, if a bubble removing part is required to be added, the position, the volume and the working mode of the part are matched with the structure of the prior contact lens case, the redesigning of the basic structures is time-consuming and labor-consuming undoubtedly, and the best method is to directly add new parts without changing the original structure.

In order to solve the two problems, the inventor creatively proposes the idea of adding the defoaming net through research and experiments. On one hand, the kinetic energy of the upward movement of the foam is reduced, and the surface pressure condition of the foam is changed to ensure that the foam on the surface layer is broken in advance; on the other hand, the structure of the existing glasses case is not required to be changed, only one universal bubble removing component is arranged at the corresponding part of the glasses case, the bubble removing component is not required to be processed, and the using method of the glasses case is not required to be adjusted.

In the process of upward movement of the foam, the foam is firstly hindered by the foam removing net 9, the foam removing net 9 has a certain weight and area (which can be adjusted according to actual needs), so that upward kinetic energy of the foam can be consumed to a large extent in the process of jacking the foam removing net 9, the compressed foam can maintain a high internal pressure level, some foams are extruded by the gravity of the foam removing net 9 to be broken, the broken foam can release a part of space, the foam removing net 9 can descend under the action of gravity to find a new balance with the foam, and the process can be performed repeatedly. Of course, in most cases the rising and falling of the bubble removal net 9 is not equidistant or regular. Meanwhile, the foam removing net 9 is provided with a plurality of through holes 11, when foam rises to the through holes 11, the foam can be extruded to the through holes 11 from the periphery and gushes into a narrow open space, and the surface stress state changes suddenly, so that the partial foam can be broken. After the foam continues to rise along the through-holes 11 beyond the defoaming net 9, a large open space with a much lower pressure is entered, and the internal stress is greater than the external stress, which also causes the rupture of a part of the foam. In general, the defoaming net 9 with a plurality of through holes 11 is equivalent to a filter screen, and a considerable part of foam is broken after passing through the through holes 11 of the defoaming net 9. Although the fixed defoaming net can play a certain defoaming role, most foams continue to flow upwards because the work is not obvious. The foam removing net 9 can repeatedly move up and down by means of the matching holes 10 and the plate-shaped support 4, so that foam continuously does work outwards in the upward movement process, and upward kinetic energy of the foam is consumed. In this case, the function of the defoaming net 9 of the present invention can be fully exerted.

When the bubble removing net 9 moves upwards, the upper surface of the bubble removing net can basically contact with the lower surface of the box cover 1. Under the condition that the shape of the central hole 10 is designed reasonably, the bubble removing net 9 can freely move up and down for a longer distance relative to the plate-shaped support 4 through the matching hole 10, namely the distance from the upper surface of the mesh enclosure 7 to the lower bottom surface of the box cover 1. Of course, the distances of the different types of existing hydrogen peroxide contact lens cases are not consistent, but only have a certain influence on the final effect of the invention, and the positive effect is generated in general. Therefore, the existing hydrogen peroxide contact lens box is required to be additionally provided with the defoaming net, and the basic structure of the existing hydrogen peroxide contact lens box is only required to meet the requirement that the defoaming net can move up and down along the plate-mounted bracket. The invention has the outstanding advantage that the structure of the prior hydrogen peroxide contact lens box does not need to be greatly changed, and only the prior structure is sleeved with the defoaming net. As shown in fig. 4-6, the cases of the glasses cases in the three embodiments are different, the structures of the upper end connecting parts are different, the structures of the vent holes are different, and even the structures of the vent holes are different without a platinum ring, however, the bubble removing net of the invention can be additionally arranged without exception, which is very important for all manufacturers of hydrogen peroxide contact lens cases.

In a general hydrogen peroxide contact lens case, a platinum surface annular body 5 is connected to the end of a plate-like holder 4. The platinum can enable hydrogen peroxide to react quickly, a large amount of oxygen bubbles can be generated on the surface (especially the lower surface) of the platinum ring, the bubbles rise above the liquid level of the care solution, and most of the oxygen bubbles become foams and are accumulated on the surface of the care solution. However, a small amount of hydrogen peroxide glasses cases without platinum rings exist in the market, and the principle is that neutralization tablets are put into the glasses cases to react with hydrogen peroxide care solution, so that sterilization is realized, as shown in fig. 6. However, the disinfection method is not convenient as the platinum ring is used, and the hydrogen peroxide is difficult to supplement after the nursing solution is lost, because once the tablet is neutralized, the tablet needs to be put in again, the cost is increased, while the platinum ring method has no problem, and the hydrogen peroxide can be supplemented at any time to perform neutralization reaction at any time. However, the present invention is applicable to both of these two types of hydrogen peroxide glasses cases, because the structures of the two types of hydrogen peroxide glasses cases are not significantly different except that whether the platinum ring is connected to the lower end of the plate-shaped bracket or not.

Referring to fig. 8, in order to better realize the defoaming function, the specific structure of the defoaming net 9 can be optimally designed. Such as: the inner wall of the through hole 11 is inclined outwards from bottom to top; the side wall of the bubble removing net 9 inclines outwards from bottom to top. Under these two kinds of circumstances, the foam meets the inclined plane structure of falling trapezoidal in the rise in-process, because open area constantly increases, can make the rise speed of foam slow down, has consumed a part of kinetic energy to surface layer foam surface area can increase under the effect of surface tension, has increased the cracked probability of foam. For another example, the inner wall of the fitting hole 10 is inclined inward from bottom to top and has a regular trapezoid shape. The design enables the defoaming net 9 to be correctly sleeved in the upper end connecting part 8 for rotatably connecting the net cover 7 and the plate-shaped support 4 under most conditions, and the movement distance of the defoaming net 9 is as long as possible by utilizing the existing structure as far as possible. Because the foam removing net 9 does not move up and down in a standard manner in the relatively viscous nursing liquid, in this case, the inclined surface design is adopted, so that the foam removing net can easily fall on the mesh cover 7, meanwhile, the area of the matching holes 10 can be slightly reduced, and excessive foam is prevented from directly drilling out from the matching holes 10 without passing through the through holes 11. These designs all increase the chance of foam collapse to some extent.

Further, the bubble removing net 9 may have through holes 11 of a circular shape, a rectangular shape, a triangular shape, a rhombic shape, a regular pentagonal shape, or a regular hexagonal shape. Of course, any shape that is convenient to machine is generally acceptable. The area of the through holes 11 accounts for 50-70% of the area of the defoaming net 9, and the area of a single through hole is not more than 5% of the area of the defoaming net 9. The small occupied area of the through holes 11 can form the condition that the gravity of the defoaming net 9 is mainly used for working, the large occupied area can reduce the weight of the defoaming net 9, and the defoaming effect can be influenced to a certain extent. The area of the single through-hole 11 is too large to maintain high pressure inside the foam, and to have an effect that the foam is pressed against each other and suddenly enters an open space.

The box cover 1 is provided with a vent hole 12. There is no special requirement on the structure and number of the vent holes 12, and according to the technical scheme of the invention, the higher the ventilation efficiency of the vent holes 12, the better.

As an alternative screen attachment, each screen 7 may be rotatably fixed to the lower portion of the plate bracket 4 by a lower end attachment portion. This has an effect on the invention in that a part of the travel distance of the blister web 9 may be lost, since the blister web 9 will not be nested in the upper end connection 8. However, the glasses case with a low height connecting part has no influence, and the smoothness and distance of up-and-down movement of the bubble removing net 9 can be increased.

Preferably, the upper end of the plate-shaped bracket 4 is detachably connected to the box cover 1, and the lower end of the plate-shaped bracket 4 is detachably connected to the annular body 5. This structure can facilitate the installation and the dismantlement of removing bubble net 9.

In conclusion, the contact lens case has the advantages that the bubble removing net of the core component is simple to manufacture, and the cost is basically not increased compared with the existing contact lens case; the use is simple, and the use method is the same as that of the existing glasses case under normal conditions; after the lenses are placed in the glasses case according to the specified procedures, the probability that the foam flows out of the glasses case is greatly reduced; the bubble removing net is suitable for over 90 percent of hydrogen peroxide contact lens boxes on the market, and is convenient to reform.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
