Description

Multifunctional contact lens box

Technical Field

The present invention relates to a multifunctional contact lens case, and more particularly, to a contact lens case that can realize a plurality of functions and is low in cost.

Background

The contact lens cases which are most common at present are usually given by contact lens manufacturers or contact lens care solution manufacturers, so that due to cost reasons, only the basic function of holding contact lenses can be generally completed. However, the contact lens cases in the market (refer to the great-complexity kyoto store and the tianmao store) are only improved in appearance by a certain amount, or the contact lens cases, tweezers, liquid medicine and the like are placed in one case to improve the usability, so that the improvement on the functions of the contact lens cases is very small.

The contact lens case (see fig. 1) currently given with contact lenses basically comprises two parts, namely a case cover and a case body, wherein the case body is integrally formed with two bowl-shaped accommodating parts for accommodating the contact lenses, the case cover is arranged above each accommodating part, and after the contact lenses are put into the accommodating parts, the case cover is covered. Such contact lens cases, while simple in construction, inexpensive to manufacture, and simple to use, have several problems. One can make the front and back of the lens difficult to determine. As is known, when the contact lenses are worn, the front and the back of the contact lenses need to be distinguished, if the contact lenses can be taken out from the lens box from the front upwards at each time, the contact lenses can be greatly convenient for a wearer, and the complex work of distinguishing the front and the back is not required to be repeated at each time. However, the conventional contact lens cases generally have a depth of, for example, 1 cm, for easy access, to ensure that the lenses are immersed in sufficient solution and to maintain the water content of the lenses, and to ensure that the lenses do not dry out during storage, at least three quarters of the solution is placed in the case. Therefore, the volume of the accommodating part is very large relative to the lens, if the spectacle case vibrates or overturns under external force, the contact lens can continuously roll in the spectacle case, and the lens is very soft, the front side and the back side are easy to convert, so that the front side and the back side of the lens are possibly changed and difficult to determine. In addition, no matter the front and back of the contact lens are put into the nursing liquid, the contact lens can be in the same state, and after the spectacle case is opened, a wearer can not directly judge whether the front of the contact lens faces upwards or not only by naked eyes, and can not directly wear the contact lens, and the front and back of the contact lens are required to be determined again. And the second is the inability to provide any function other than storage, such as relatively securing the lens. In many cases, the front and back surfaces of the contact lens need to be re-defined. For example, when the contact lens is worn for the first time, the contact lens is not packaged according to a certain front and back rule when a manufacturer packages the contact lens into a transfer box; for example, in the process of repeatedly rubbing and cleaning the lens by a wearer, the lens is easy to curl and turn; for another example, the front and back sides can be uncertain due to some special reasons, such as the turning of the glasses case or the falling of the glasses during wearing.

Under these circumstances, the person of wearing need be held between fingers in two fingers and extrusion glasses side lower part with the lens is uncovered up, perhaps places the lens bulge at a finger tip, carefully observes the present crooked state of lens upper edge, is the front when seeing lens side upper edge be the bowl dress cambered surface (radian is upwards inwards), is the reverse side when being the disc cambered surface (radian is outwards), then adjusts the contact lens and openly towards eyes and wear again. However, the two methods have disadvantages that the position of the finger and the force of the squeezing are difficult to grasp, and the lens is easy to fall off due to the force required by a certain skill. In the latter, since the convex arc surface of the lens faces downwards, a large amount of care solution flows to the lowest part along the arc surface after being taken out of the care solution, and meanwhile, a large amount of care solution is adhered to fingers when the lens is taken out, so that the condition that the central area of the lower part of the lens is adhered to the end parts of the fingers and is inwards sunken (namely, the lens is approximately bowl-shaped when viewed from the side surface, but the middle part of the bottom is upwards convex) is often presented due to the viscosity and the flexibility among the solutions when the lens is placed at the tip of a hand. At this time, if the adhesion area is large, the stress position of the lens is changed, and the radian characteristics of the lens are not easy to clearly display, namely, whether the lens is bowl-shaped or disc-shaped can not be clearly distinguished.

In the prior art, there are also designs in which corresponding structures are provided in the contact lens case to prevent lens movement. However, two problems usually exist in the products, one is that the most part is to cooperate with other structures, such as an automatic lens lifting structure, to prevent the lens from moving during the lens lifting and lowering process; for example, the adhesive can be attached to a predetermined portion of a component to facilitate direct access by the wearer. In such a structure, the lens is not taken out by the fingers of the wearer, but is taken out or moved by some automatic lifting mechanism or automatic adsorption mechanism, so that the complete conformity of the lens is emphasized, a profiling model which is consistent with the radian of the side surface of the lens is basically adopted, and a good limiting effect is required to be achieved, so that the structure is complex, the manufacturing process is complex, and the lens is particularly difficult to clean; in addition, the requirement on the position is high when the lens is placed, the lens needs to be accurately placed at a preset position, otherwise, the lens is easily damaged when the limiting mechanism is opened and closed; and many times will place the lens on bellied base or sucking disc, need the person of wearing to grasp the lens with two fingers, place the lens openly down (protruding upwards), make the lens drop very easily. The traditional contact lens box is very convenient when lenses are put in, the edges of the lenses are directly pinched after cleaning is completed and then the lenses are put in nursing liquid, and the accommodating part is very wide relative to the lenses, so that the contact lens taking and placing of any age group wearer is not difficult. And secondly, the limiting parts of the products do not mention other functions except limiting. Rubbing the washing lens repeatedly at the person of wearing, the spectacle case rolls or wears the in-process glasses and drops under the circumstances such as, do not have any product to possess the function of supplementary discernment lens positive and negative, and in fact, its limit structure also can't accomplish supplementary discernment's effect, can only rely on the person of wearing to use the finger to distinguish again.

In view of the above, there is a need in the market for a multifunctional spectacle case that is inexpensive, easy to manufacture, and easy to clean, and that can significantly improve the convenience and practicality of the existing contact lens cases.

Disclosure of Invention

The present invention is directed to a multi-functional contact lens case that can fix lenses and provide auxiliary resolution of front and back sides, in response to the above-mentioned drawbacks of the prior art.

In actual wearing, the bowl-shaped and the plate-shaped are relatively small in difference, and once the bowl-shaped and the plate-shaped are disturbed by the outside, the bowl-shaped and the plate-shaped are not easy to distinguish. The inventor obtains through observation that firstly, the lens is dry, the water content of the lens is reduced, the lens is relatively stiff, and if fingers are dry, namely the whole nursing liquid is less, the front and back shapes are easy to recognize; secondly, when the supporting point is close to the side surface of the bottom of the lens, the stress interference on the upper edge of the lens is small, and the shape is easy to identify.

Accordingly, the technical scheme adopted by the invention for solving the technical problem is as follows: the multifunctional contact lens box comprises a box cover and a box body, wherein the box body comprises two accommodating concave parts which are connected into a whole through a connecting part, at least three limiting rods with the same height are integrally formed on the box cover, the distance between the limiting rods and a central point A of the bottom surface of the box cover is equal, and the limiting rods are symmetrically arranged around the central point A.

Preferably, the circular area enclosed by the limiting rods is 1.4% -12% of the projected bottom area of the inner wall of the accommodating concave part. The circular area enclosed by the limiting rods is equal to 4% -34% of the projection area of the contact lens placed in the accommodating concave part. The diameter of the limiting rod is 0.5-1.0 mm. The distance between the limiting rod and the central point A of the box cover is 1.5-4 mm. The head distance of the limiting rod is not more than 1mm from the contact lens placed in the accommodating concave part. The bottom surface of the accommodation recess is substantially in the shape of a concave arc. The head of the limiting rod is an arc surface. The head of the limiting rod inclines 20-30 degrees towards the center of the box cover.

The multifunctional contact lens box has the following beneficial effects: first, the contact lens case of the present invention can achieve two very important functions without increasing the cost by adding a simple structure by only making a small change to the mold of the case cover. Secondly, can prevent that the contact lens from rolling in the spectacle case and shifting for the person of wearing can not need to worry about placing and the mode of carrying of contact lens case, can all open the spectacle case just can confirm the front of lens under most circumstances, thereby directly wear. Thirdly, under special conditions (such as wearing for the first time, repeatedly cleaning or wearing again after dropping), the box cover can be placed on the desktop upside down, and the lenses are placed right above the three limiting rods of the box cover; meanwhile, the nursing liquid stuck on the lens can flow to the center below the lens or the lower part of the limiting rod, so that the interference of the nursing liquid and fingers on the lens is minimized, and the front side and the back side of the lens can be determined quickly and accurately. Third, the basic usage, habits and difficulties of use of the contact lens case need not be adjusted, and the contact lens case is the same as the contact lens case of the prior art. That is, the invention greatly facilitates the contact lens wearers by adding two very practical additional functions of 'zero' manufacturing cost and 'zero' using cost on the basis of the existing contact lens case, and meanwhile, the invention is suitable for the improvement of contact lens cases with various shapes due to strong universality, can add 'zero' cost to the given contact lens case, and is also very beneficial to a great number of contact lens manufacturers.

Detailed Description

In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and specific embodiments, and it should be understood that the following examples are implemented on the premise of the technical solutions of the present invention, and the detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following examples.

Referring to fig. 2, the multifunctional contact lens case of the present embodiment includes a case cover 1 and a case body 2, the case body 2 includes two accommodating recesses 3 connected as a whole, at least three equal-height limiting rods 4 are integrally formed on the case cover 1, the limiting rods 4 extend outwards from the bottom surface of the case cover 1, the distance between the limiting rods 4 and the central point a of the bottom surface of the case cover 1 is equal, and the limiting rods 4 are symmetrically arranged around the central point a.

The details of each structure are set forth in more detail below.

Referring to fig. 2 to 3, the cap 1 of the present invention has two, substantially circular bottom surfaces, side surfaces having a certain depth, and inner walls of the side surfaces formed with threads. Still include box body 2, box body 2 includes two holding recess 3 as an organic whole even, and holding recess 3's shape corresponds with lid 1, and its side foreign currency is formed with the screw thread to guarantee that lid 1 can seal and screw to holding recess. As is the case with prior art contact lens cases.

Furthermore, the inner side of the bottom surface of the box cover 1 is integrally formed with a plurality of limiting rods 4 with the same height, the distance between the limiting rods 4 and the central point A of the bottom surface of the box cover 1 is equal, and the limiting rods 4 are symmetrically arranged around the central point A. When the three limiting rods are used as a limiting box cover, the limiting rods are equal in height and symmetrically arranged around the central point A, stress points can be uniformly distributed on the cambered surface of the lens, the limiting rods and the bottom surface of the accommodating concave part are utilized to limit the lens to move in a smaller range, and the phenomena of rolling and the like cannot occur; meanwhile, the lens 5 is positioned in the middle of the bottom surface of the accommodating concave part 3, so that the edge of the lens 5 is prevented from being always attached to the side wall due to the action of surface tension and static electricity, and possible lens damage is avoided; when the device is used as an auxiliary distinguishing device, the limiting rod 4 can be ensured to support the lens, and a good observation state can be obtained; and because the quantity of gag lever post is few, simple structure, be favorable to organizing on the one hand to produce, on the other hand the lens atress is stable, reasonable, also does benefit to simultaneously and washs and the cambered surface shape that the person of wearing observed the lens. Of course, the number of the stop rods 4 is not limited to 3, but the function of the present invention is not substantially enhanced except that the number of the stop rods is increased to distribute the stress. There is such a condition because gag lever post 3 self has certain diameter, and its quantity is many after certain degree, has closely leaned on together, and at this moment, too intensive gag lever post 3 has caused the inside of its encirclement to be difficult to clear problem, does not have essential promotion to the limit function of lens simultaneously yet.

By adopting the limiting rod structure, the lens moves towards the outer direction of one limiting rod under the action of external force according to inertia or along with the nursing liquid, but a stable state is formed because the lens is blocked by the other two limiting rods in the opposite direction. Meanwhile, the invention utilizes a plurality of limiting rods which are vertically arranged in a large space to divide the accommodating space of the contact lens box in the prior art into a plurality of parts, thereby not limiting the flow of the nursing liquid, ensuring the water content of the lens, greatly limiting the moving space of the lens and reducing the rolling probability.

Meanwhile, by adopting the limiting rod structure, when a wearer needs to manually distinguish the front side and the back side of the lens, the box cover 1 can be placed on the desktop upside down, the top surface of the box cover 1 is relatively flat, three limiting rods 4 on the inner wall of the box cover 1 are stably erected upwards, the lens is placed right above the limiting rods 4, the lens is supported from the position, close to the middle, of the lower part of the lens 5, and the lens 5 has a certain radian, so that the supporting force of the head 6 to the lens 5 presents component forces in the horizontal direction and the vertical direction, the effect similar to finger extrusion and support is achieved, and the lens presents a bent shape which is convenient for the wearer to observe the upper edge of the lens from the side surface; meanwhile, the nursing liquid adhered on the lens can flow to the center below the lens, interference of the nursing liquid and the adhesion of fingers on the lens is reduced to the minimum, and the front side and the back side of the lens can be determined quickly and accurately. In practice, the nursing liquid has a relatively large influence on the curved shape of the lens, and due to the tension and gravity of the nursing liquid, the contact lens is easy to judge whether the upper edge is bowl-shaped or disc-shaped after the nursing liquid is lost or evaporated more, i.e. dried.

The contact lens case of the present invention is designed with a large number of dimensional parameters, such as the diameter of the bottom surface of the receiving recess, the curvature of the bottom surface, the depth of the side surface, the diameter of the case cover, the height of the case cover, the distance of the stopper rod from the center point a, the height of the stopper rod, and the diameter of the cross section of the stopper rod. However, since the range of lens sizes of contact lenses is approximately constant, other sizes must be matched to the contact lenses within a range in order to maintain the stability of the lenses and the feasibility of identifying the front and back when the lenses are inverted.

It is well known that the diameter of a common contact lens is between 14-15 mm. In order to maintain a sufficient amount of the solution in the receiving recess and facilitate insertion and removal of the lens, the diameter of the lens is typically 55% to 60% of the diameter of the bottom surface of the case body 2 of a conventional contact lens case, and more typically 25mm, which is, of course, the projected dimension of the bottom surface of the receiving recess. Therefore, in order to match with a general contact lens and a contact lens case, the distance between the stopper rod 4 and the central point A of the case cover 1 can be set to be 1.5-4mm, not only by controlling the movement of the lens using the head 6 of the stopper rod 4, but also by supporting the lens 5 using the head 6 without affecting the curved shape of the upper edge of the lens. Since the limiting rod 4 has a certain cross-sectional diameter, which is usually 0.5-1.0mm, in order to ensure that the limiting rod 4 is not easily broken, the distance between the limiting rod 4 and the central point a of the box cover 1 is usually the distance from the central point to the central point. If the size of the lens is too small, the moving space of the lens is too large, the possibility of entering the area between the limiting rod 4 and the inner wall of the accommodating concave part 3 is increased, and the probability of rolling is increased; if the size of the lens box is too large, the head 6 of the limiting rod 4 is too close to the upper edge of the lens 5, the height of the limiting rod 4 is reduced, due to the characteristic that the lens is soft and easy to bend, the lens is easy to separate from the head 6 of the limiting rod and is inserted into the middle of the limiting rod 4 or between the limiting rod 4 and the inner wall of the accommodating concave part, the placing posture of the lens 5 cannot be unfolded, and when the lens box is placed at a normal position again, the lens 5 may not return to the bottom of the accommodating concave part and cannot be fully soaked in the nursing solution, so that unnecessary lens damage is; meanwhile, when the box cover 1 is used in an inverted mode, the head 6 of the limiting rod 4 supports the lens 5 too far to be inclined to the edge of the lens, and the stress point is too close to the upper edge of the lens, so that the upper edge obtains extra supporting force and the stress state is changed, even the lens collapses downwards, the upper edge cannot be in a bent state under a natural placing state, and the correct bent state of the upper edge of the lens cannot be distinguished.

Further, other methods may be used to define the position of the stop rod 4. For example, the circular area enclosed by the limiting rod 4 is equivalent to 4% -34% of the projection area of the contact lens 5 placed in the accommodating concave part 3. The circular area enclosed by the limiting rod 4 is equal to 1.4% -12% of the projected bottom area of the inner wall of the accommodating concave part 3. Of course, this limitation is not essential to the previously described method, but is essential to limit the position of the stop bar 4 from being too close to or too far from the center point a. Through simulation experiments of the inventor, within the numerical range limited at present, two newly added functions of the invention can be realized.

Among a plurality of sizes, the distance from the head 6 of the limiting rod 4 to the contact lens placed in the accommodating concave part 3 is also very important, and if the distance between the head 6 of the limiting rod 4 and the bottom surface of the accommodating concave part 3 is too long, the lens placed in the interval has too large moving space, can shake under the action of inertia, and obviously cannot play a good limiting role. Therefore, in the case of lenses having a depth of 3.5-4.5mm as is common, the distance of the head 6 from the lens 5 is preferably not more than 1 mm. Of course, if the position of the limiting rod 4 is different at this distance, the height of the limiting rod is also different, and the closer to the center of the lens, the larger the concave of the lens is, the higher the height of the limiting rod is, so that the lens can be pressed close to.

Preferably, the bottom surface of the concave accommodating portion 3 is substantially concave arc-shaped, and the shape of the bottom surface of the lens 5 is matched with that of the lens, so that the movable section of the lens 5 can be further compressed.

Preferably, the head 6 of the limiting rod 4 is a circular arc surface, so that the impact of the head 6 on the lens 5 can be reduced, and the lens 5 can be protected properly.

Preferably, the limiting rod 4 can be divided into a vertical part and a head part 6, wherein the head part 6 inclines 20-30 degrees towards the center of the box cover, the head part 6 has a certain length, and the distance between the whole head part 6 and the lens 5 is basically maintained below 1 mm. This design does not change anything in the manufacturing process, but the head 6 is extended relative to the surface of the lens 5, changing the stop 4 into a rod with a bent portion. In this case, the control area of the limiting rod 4 is obviously increased, and the possibility of the rolling of the lens 5 is further reduced; at the same time a single point of force becomes possible with multiple points of force, it is possible to distribute the forces to which the lens 5 is subjected during vigorous movements.

In conclusion, the multifunctional contact lens case is simple to manufacture, and the cost is not increased compared with the existing contact lens case; the use is simple, the use method is the same as that of the existing glasses case under normal conditions, and the glasses case can be directly placed on a desk upside down under other conditions; after the lens is placed in the mirror box according to the preset front and back surfaces, the possibility of the lens inversion is almost reduced to zero, and the lens is not easy to move in the mirror box; meanwhile, the front and back sides of the lens can be distinguished quickly and accurately by using the glasses box cover.

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.
