Description

The present invention relates to a soft contact lens storage case, and particularly to a storage case that allows soft contact lenses to be stably removed from a lens storage portion without touching the rear (inside) surface.

Conventionally, contact lenses (hereinafter referred to as CL) have been stored by being immersed in a liquid contained in a container, except when the contact lens is being worn. In this container, the CL is subjected to actions (treatments) such as cleaning, disinfection, and improvement of surface wettability using a special liquid stored therein, and the lens functions as a lens until the next time it is worn. maintenance and recovery are being carried out.

By the way, when the CL is taken out from the liquid in the container containing the CL and placed on the eye of the wearer, the CL will be handled by the wearer's fingers, If the wearer's fingers touch the back surface (inner surface) of the CL, dirt on the fingers and bacteria that adhere to the fingers will adhere to the back surface of the CL, which may reduce its function as a lens or cause damage to the wearer. There is an inherent fear that it may cause inflammation in the eyes of patients. In particular, among CLs, soft contact lenses (hereinafter referred to as SCLs) have low rigidity and are susceptible to deformation, so even if careful handling is taken, when the SCL is attached to and removed from the eye, the posterior surface of the SCL This makes it easier for the wearer's fingers to touch the surface.

Therefore, various containers or cases for containing and holding the SCL have been proposed in order to prevent fingers from touching the rear surface of the SCL as much as possible. (WO) No. 2013/140452 discloses a CL storage case with a novel structure that can prevent contamination and improve operability when taking CL out of a storage recess.

That is, such a CL storage case includes a container body with a storage recess in which the CL is immersed and held in a storage solution with its inner surface (rear surface) facing upward, and such a storage recess. The lid is provided with a downward protrusion extending downward, and a suction holding part having a spherical convex shape is provided on the lower surface of the downward protrusion, and the suction holding part is provided with a CL. CL is configured so that it can be suction-held, and thereby the lid body can be removed from the container body while the inner surface of the CL is suction-held by the suction-holding part of the downward protrusion. When taking out the CL from the storage recess, the fingers do not touch the inner surface of the CL, and contamination of the inner surface of the CL due to finger contact can be advantageously prevented.

However, in a CL storage case with such a configuration, in order for the inner surface of the CL to be suctioned and held by the suction holding part of the downward protrusion provided on the lid, the CL must be accurately sunk into the center of the storage case. , it is necessary to close it with the lid body, and if the CL is stored in a state shifted to the side instead of in the center of the case, when the CL is closed, the CL will not be attracted to the suction holding part and it will be difficult to take it out. There was a problem that made it impossible to do so.

Moreover, in order to hold the CL by suction, the distance between the lower surface of the suction holding part and the bottom of the CL accommodation recess must be kept small so that the CL is located close to the suction holding part. However, if this is done, the amount of storage solution held in the CL accommodation recess will inevitably decrease, resulting in the problem that the treatment effects such as cleaning and disinfection of the CL cannot be fully achieved. In addition, when the gap between the lower surface of the suction holding part and the bottom surface of the accommodation recess becomes narrower, the movement of the CL positioned within such a gap is restricted, and the center of the accommodation recess becomes narrower. If the CL is housed in a biased form, there is a problem that it becomes difficult to suction and hold the CL to the suction holding part of the downward protrusion of the lid. Of course, by reducing the inner diameter of the storage recess in the storage case and narrowing the gap between it and the suction holding part, it becomes easier to position the CL in the center of the storage recess. This inevitably results in a decrease in the amount of the storage solution in the CL storage solution, which also causes the problem that the treatment effect of the CL storage solution is reduced. In addition to the problem that it is difficult to store the CL in the facility, there is also the problem that there is a risk that the CL may be deformed due to physical interference if the CL is stored for a long time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to clarify the configuration of the present invention more specifically, typical embodiments of the present invention will be described in detail below based on the drawings.

First, FIG. 1 schematically shows an example of an SCL storage case according to the present invention in the form of a top view, a front view, and a bottom view, respectively. FIG. 2 also shows such an SCL storage case in the form of a perspective view. Here, the SCL storage case 10 is snap-fitted into a bottomed cylindrical container body 12 in which a predetermined liquid is stored and an opening that opens above the container body 12, so that it can be attached and removed in a liquid-tight manner. The container body 12 includes a cap (lid body) 14 that can be attached to the container body 12 to form a sealed space as a lens storage section. Here, the SCL storage case 10 has two container bodies 12, 12 and two caps 14, 14 in order to store and hold the SCL for the right eye and the SCL for the left eye, respectively. , polyethylene, polypropylene, polycarbonate, or other synthetic resin by a known integral molding operation such as injection molding.

By the way, these two container bodies 12, 12 are connected at their upper parts by a plate-shaped body connecting part 16, and as is clear from FIGS. 1(b), (c) and 4(b). Thus, the two container bodies 12, 12 are reinforced by the two reinforcing ribs 18, 18, and have a structure that makes it difficult to bend the two container bodies 12, 12 between them. In addition, as shown in FIG. 1(a), the letters L and R are formed in embossed form in the parts of the main body connecting part 16 that are close to the two container main bodies 12, 12, and are designed for the left eye. and the container body 12 in which the SCL for the right eye is to be accommodated are designated. Further, the upper peripheral edge of the cap 14 is connected to the peripheral edge of the two container bodies 12, 12 on the side opposite to the opposite side of the opening, and by making the connecting portion thinner, As shown in FIGS. 1 and 3(a), a thin hinge portion 20 is formed therein in a direction perpendicular to the direction in which the container body 12 and the cap 14 are connected. Therefore, when the hinge portion 20 is bent and the cap 14 is rotated, the opening of the container body 12 is covered with the cap 14 and sealed tightly, as shown in FIGS. 6 and 7. It is possible that the

As described above, since the cap 14 is rotated by bending at the hinge portion 20 and is snap-fitted into the opening of the container body 12, the cap 14 is shown in FIGS. 1, 2, 3(a), etc. It is shown in an upside-down configuration. The cap body (lid body) 14a of such a cap 14 is integrally provided with a cylindrical lower protrusion 14b that protrudes downward from its inner surface, and furthermore, this lower protrusion 14b A dome-shaped lens holder 22 that protrudes downward and holds the SCL by suction is integrally provided at the lower end of the lower protrusion 14b so as to close the lower end of the lower protrusion 14b. Further, in order to facilitate attachment and detachment of the cap 14 to the opening of the container body 12, a tongue-shaped gripping piece 14c that protrudes laterally from the peripheral edge of the cap body 14a of the cap 14 is provided on the side opposite to the hinge part 20. The cap 14 is integrally provided so that the cap 14 can be attached and detached by holding the gripping piece 14c between fingers. The dome-shaped lens holding part 22 has a smooth outer surface in order to attract and hold the SCL, and has a spherical outer surface with a radius of curvature larger than that of the rear surface (inner surface) of the SCL. In particular, by setting the radius of curvature of the outer surface (lower surface) of the lens holding portion 22 to about 9.0 to 10 mm for a normal size SCL, the SCL can be used as a lens. Even when the holding portion 22 is located not in the center but near the edge, stable suction is possible, and due to the presence of the vertical ribs 24 and horizontal ribs 26 as described below, the suction and holding action of the SCL can be advantageously exhibited. .

The container body 12 is shown in FIGS. 1(a) and (b), FIG. 2, FIGS. 3(a) to (c), and FIGS. 4(a) and (b), and is further enlarged in FIG. As shown, on the inner surface of the cylindrical wall portion 12a of the container body 12, a plurality of vertical ribs 24 of a predetermined height are arranged at a predetermined distance (in this case, a phase difference of 30°) in the circumferential direction. , are provided radially in a direction toward the center of the cylinder wall portion 12a. The vertical ribs 24 are arranged so as to extend in the vertical direction of the cylindrical wall portion 12a of the container body 12, and the upper corners thereof are curved in an arc shape and reach the bottom portion 12b of the container body 12. formed in length. On the other hand, as can be seen more clearly from the enlarged view of FIG. They are arranged radially at predetermined intervals (in this case, a phase difference of 30°) in the circumferential direction of the bottom portion 12b, and extend while decreasing (in this case, the height gradually decreases linearly). Here, the plurality of vertical ribs 24 and the plurality of horizontal ribs 26 are disposed within the cylinder of the container body 12 as an integral rib.

More specifically, the plurality of vertical ribs 24 are located on the inner surface of the cylindrical wall portion 12a of the container body 12, facing the connection portion (20) between the container body 12 and the cap 14, and opposite to the connection portion. It is composed of five vertical ribs 24a and seven vertical ribs 24b located on the inner surface of the cylindrical wall portion 12a of the container body 12 on the side of the connecting portion (20). The five vertical ribs 24a located on the opposite side of the cap 14 are provided at a lower height than the seven vertical ribs 24b located on the cap 14 side. When the lower protrusion 14b is inserted into the container body 12 by being rotated at the bend of 20, interference of the lower protrusion 14b can be avoided. As described above, since the cylindrical downward protrusion 14b provided on the inner surface of the cap 14 is inserted into the container body 12, the tops of the plurality (12) of vertical ribs 24 (24a+24b) The size of the approximately circular shape formed at the upper end is larger than the outer shape of the lower protrusion 14b, and therefore larger than the outer diameter of the SCL held by suction on the lens holding part 22. ing. The distance between the vertical ribs 24 (24a, 24b) and the outer peripheral surface of the lower protrusion 14b is generally 0.5 mm to 0.5 mm in order to effectively hold the SCL to the lens holding part 22 by suction. It will be approximately 1.5 mm.

Moreover, the plurality of horizontal ribs 26 disposed on the bottom part 12b of the container body 12 are arranged so as to extend continuously from the lower end of the corresponding one of the plurality of vertical ribs 24 (24a+24b) above the bottom part 12b. As is clear from FIG. 1(a), FIGS. 3(a) to (c), FIG. 4(a), etc., two types of ribs having different lengths in the radial direction of the bottom portion 12b of the container body 12 are provided. That is, it is composed of long horizontal ribs 26a and short horizontal ribs 26b, and these horizontal ribs 26a and 26b are arranged at intervals of 30 degrees in the cylinder of the container body 12 so that they are alternately located in the circumferential direction. They are arranged radially extending from the wall portion 12a toward the center of the bottom portion 12b. These two types of horizontal ribs 26a and 26b are provided so that the height decreases linearly toward the center of the bottom portion 12b of the container body 12. That is, as shown in an enlarged view in FIG. 5, among the two types of horizontal ribs 26, one horizontal rib 26a is higher than the other horizontal rib 26b, and the center of the bottom 12b of the container body 12 is It is arranged so that it extends close to and then disappears. In this way, the presence of the two types of horizontal ribs 26a and 26b having different lengths and heights allows the SCL 32 (see FIG. 6) that is accommodated unevenly to enter, making it easier to guide the SCL 32 to the center. -ing

Furthermore, in the state in which these two horizontal ribs 26a and 26b are provided, they are provided at the center of the inner surface of the bottom 12b of the container body 12 and at the lower protrusion 16b of the cap 14 that is snap-fitted to the container body 12. The accommodation gap a (see FIG. 6) of the SCL 32 formed between the lowermost surface of the lens holding part 22 and the lowermost surface of the lens holding part 22 is generally about 0.25 mm to 0.78 mm in order to effectively hold the SCL 32 by suction. At the same time, such an SCL 32 accommodation gap gradually becomes larger between the horizontal ribs 26 (26a, 26b) and the lower surface of the lens holding part 22 as it goes from the center of the bottom part 12b toward the cylinder wall part 12a. It is configured.

Here, in order to attach the cap 14 to the opening of the container body 12 in a liquid-tight manner, a fitting is fitted at a predetermined height over the entire circumference of the upper end of the cylindrical wall portion 12a of the container body 12. A fitting convex portion (annular protrusion) 28 is integrally provided, while a fitting recess (fitting groove) 30 having a predetermined depth and opening downward is formed in an annular shape on the peripheral edge of the cap main body 14a of the cap 14. It is set in. Further, the fitting convex portion 28 is formed with a bulge such that its upper end outer circumferential portion protrudes outward, while the outer circumferential portion of the fitting convex portion 28 is formed on the outside of the annular fitting recess 30 provided on the outer circumferential portion of the cap body 14a. The inner circumferential surface of is provided to bulge inward, and the bulge at the tip of the fitting convex portion 28 overcomes the bulge formed at the entrance of the fitting recess 30, By being fitted, the fitting protrusion 28 and the fitting recess 30 can be firmly and liquid-tightly fitted. That is, by bending the hinge portion 20 provided at the connecting portion between the container body 12 and the cap 14, the cap 14 is rotated and the downward protrusion 14b is inserted into the cylindrical wall portion 12a of the container body 12. At the same time, the fitting protrusion 28 provided at the upper end of the cylindrical wall portion 12a is snap-fitted into the fitting recess 30 provided at the peripheral edge of the cap body 14a. In contrast, the cap 14 can be attached in a liquid-tight manner.

Therefore, in the SCL storage case 10 having such a configuration, a plurality of vertical ribs 24 are arranged radially on the inner surface of the cylindrical wall portion 12a of the container body 12, so that the SCL 32 accommodated therein can be moved in a large horizontal direction. is regulated, and is formed between the lower surface of the dome-shaped lens holding portion 22 by a plurality of horizontal ribs 26 that are provided radially on the inner surface of the bottom portion 12b and whose height gradually decreases toward the center of the bottom portion 12b. The SCL 32 can be positioned close to the lens holding part 22 by regulating the lens housing gap, so that the SCL 32 can be stably held by suction to the lens holding part 22. Under these conditions, it becomes possible to store a predetermined liquid in the gaps between the plurality of vertical ribs 24 and the gaps between the plurality of horizontal ribs 26 in the container body 12. The amount of liquid stored in the container body 12 can be effectively increased, and a sufficient amount of liquid for holding (processing) the SCL 32 can be secured.

As shown in FIG. 6, the two container bodies 12, 12 of the SCL storage case 10 have functions such as cleaning, disinfection, and improving surface wettability for preserving the SCL 32 to be immersed. In a state in which the liquid 34 similar to the conventional one is contained, the right eye SCL 32 and the left eye SCL 32 are removed from the wearer's eye, and the lens inner surface (rear surface) is directed upward. After the SCL 32 is immersed in the liquid contained in the container body 12, the cap 14 is snap-fitted, so that the SCL 32 is immersed and held in the contained liquid 34. In addition, in FIG. 7, the SCL 32 for the right eye and the SCL 32 for the left eye are stored in the two container bodies 12, 12 of the SCL storage case 10, and the caps 14 are snapped into the respective containers to seal them. The embodiment is shown in perspective view.

Thus, in such a storage operation of the SCL 32, the SCL 32 is stored in the same way as when the inner diameter of the cylindrical wall 12a is reduced due to the presence of the plurality of vertical ribs 24 provided radially on the inner surface of the cylindrical wall 12a of the container body 12. In addition, the lens holder is moved closer to the center of the cylindrical wall portion 12a, and the lens holding portion is moved closer to the center side of the cylinder wall portion 12a. Since an effective lens accommodation gap is formed between the SCL 32 and the lens holder 22, it becomes possible to stably adsorb and hold the SCL 32 on the outer surface of the lens holder 22. Furthermore, even if the SCL 32 is accommodated not in the center of the suction surface of the lens holding section 22 but near the edge, it can be suctioned. is suctioned in a state shifted from the suction surface toward the cylinder wall portion 12a, and is taken out.

In addition, the amount of liquid contained in the liquid 34 is increased due to the presence of many gaps between the plurality of vertical ribs 24 and many gaps between the plurality of horizontal ribs 26, especially gaps formed by a combination of long horizontal ribs 26a and short horizontal ribs 26b. As a result, while the SCL 32 is held in the SCL storage case 10, the SCL 32 can be treated with the stored liquid 34, such as cleaning, disinfection, and improving surface wettability. In addition to being effectively realized, the flow (convection) of the contained liquid 34 within the SCL storage case 10 can also be effectively promoted, thereby causing the SCL 32 to move toward the center of the cylinder wall 12a. As a result, the lens can be advantageously attracted to the center of the lens holder 22.

Furthermore, even if the SCL 32 to be stored is floating on the liquid surface, the cap 14 can be snapped into the opening of the container body 12 and the lower protrusion 14b can be inserted into the lower protrusion 14b. It is also possible to make the SCL 32 stick to the lens holding part 22 provided at the tip, and when the SCL 32 is not in the center of the suction surface of the lens holding part 22 but near the edge, the cap 14 The SCL 32 is moved to the center of the suction surface of the lens holding part 22 by swinging or shaking the container body 12 which is snap-fitted to cause the liquid 34 contained in the container body 12 to flow. The position can be easily corrected, and furthermore, if the SCL 32 is left immersed for a long time, it can be expected to naturally move toward the center of the lens holding part 22.

In addition, in the SCL storage case 10 configured as described above, the container body 12 is configured integrally with the cap 14 via the connecting portion (20), and can be formed by an integral molding operation using resin. Since it is a product, it has a structure in which the number of parts is only one, and it can be manufactured at low cost.The cap 14 seals the container body 12 by snap fitting. The lower end position of the lens holding part 22 provided at the lower end of the lower protrusion 14b of the cap 14 within the container body 12 is always constant, and the lower surface of the lens holding part 22 and the inner surface/lateral rib 26 of the bottom part 12b of the container main body 12 are The lens accommodation gap formed between the bottom part 12b/horizontal rib 26 and the lens holding part 22 is always maintained at a gap effective for adsorption of the SCL 32 since the distance between the top part and the top part does not change. This contributes to stable adsorption and retention of the SCL 32 and effectively prevents suction errors from occurring.

As described above, the SCL storage case 10 according to the embodiment of the present invention shown in the drawings can be used as a container that can hold or store the SCL 32 that has been removed from the wearer's eye until the next opportunity to wear it. However, such an SCL storage case 10 is merely an example as one of the representative embodiments of the present invention, and the present invention does not include such implementation. It should be understood that the specific description of the form should not be construed as limiting in any way.

For example, in the above embodiment, two combinations of the container body 12 and the cap 14 are provided integrally to accommodate the two SCLs 32, 32 for the left eye and the right eye, but of course, one combination For the purpose of accommodating two SCLs 32, it is also possible to construct an SCL storage case that simply combines one container body 12 and cap 14. Note that in the above embodiment, the container body 12 and the cap 14 are configured as an integrated body in consideration of productivity and economic efficiency, but the container body 12 and the cap 14 may be constructed as separate bodies. There is no problem even if the container body 12 and the cap 14 are configured separately.

Further, in order to enable the cap 14 to rotate relative to the container body 12, the cap 14 is integrally connected to the container body 12 by a thin hinge portion 20. However, instead of this structure, various conventionally known rotation structures can be arbitrarily adopted. Note that, although rotation of the cap 14 is desirable from the viewpoint of operability, it is not necessarily necessary to have a structure that allows rotation.

Furthermore, even if the opening of the container body 12 is liquid-tightly closed with the cap 14, it is possible to use various known sealing methods in addition to the snap-fitting method shown in the example. For example, by screwing the cap 14 to the opening of the container body 12 using a conventional screwing method, it is also possible to adopt a liquid-tight closing structure in a removable structure. be.

Furthermore, although the downward protrusion 14b hanging down from the cap body 14a of the cap 14 has a cylindrical shape in order to reduce weight, there is no problem with it even if it has a solid cylindrical shape. The hanging length is also appropriately selected depending on the length of the container body 12 in the axial direction (vertical direction).

In addition, even if there are vertical ribs 24 and horizontal ribs 26 provided on the inner surface of the cylindrical wall portion 12a and bottom portion 12b of the container body 12, respectively, the vertical ribs 24 and the horizontal ribs 26 may be integrated. In the structure of It is also possible to arrange the ribs so that they have different phases, and furthermore, it is also possible to make the number of the plurality of vertical ribs 24 and the number of the plurality of horizontal ribs 26 different.

The number of vertical ribs 24 and horizontal ribs 26 to be provided is determined appropriately depending on the purpose of providing the ribs 24 and 26, but is generally about 8 to 16, preferably 11 to 13. The plurality of vertical ribs 24 and the plurality of horizontal ribs 26 may be arranged at regular intervals, or may be arranged irregularly at different intervals. .

In the illustrated embodiment, among the plurality of vertical ribs 24, the heights of the five vertical ribs 24a located on the side farther from the location where the cap 14 is disposed are higher than those closer to the location where the cap 14 is disposed. Although the height is lower than that of the seven vertical ribs 24b located on the side, it goes without saying that the vertical ribs 24a and 24b may have the same height. Further, even if there are horizontal ribs 26 arranged on the inner surface of the bottom portion 12b of the container body 12, the length in the radial direction of the bottom portion 12b and the height from the inner surface of the bottom portion 12b are determined by the distance between the horizontal ribs 26 and the lens holding portion 22 of the cap 14. The length of the horizontal rib 26a is appropriately selected depending on the size of the lens accommodation gap formed in the lens housing gap, and it is also possible to extend the long horizontal rib 26a to the center of the bottom portion 12b. Furthermore, in addition to the case in which the height of the horizontal rib 26 changes linearly, it is also possible to change the height in a curved manner. The low horizontal ribs 26b are designed to have a high height so that the liquid 34 in which the SCL 32 is immersed can flow well within the container body 12 and the SCL 32 can be moved to the center of the lens holding part 22, as shown in FIG. The size will be selected as appropriate. Although it is desirable that the horizontal ribs 26a and 26b having different heights are arranged alternately as in the illustrated embodiment, it is also preferable that the horizontal ribs 26a and 26b are arranged irregularly. It is also possible to configure it so that

Further, in the illustrated embodiment, a fitting protrusion 28 is provided on the container body 12 side for snap fitting between the container body 12 and the cap 14, while such a fitting protrusion 28 is provided on the cap 14 side. 28 is provided, but the fitting convex portion 28 may be provided on the cap 14 side, and the fitting recess (30) may be provided on the container body 12 side. Regarding the fitting method between the container body 12 and the cap 14, various known fitting structures may be employed as appropriate.

In addition, although not listed one by one, the present invention can be implemented in embodiments with various changes, modifications, improvements, etc. based on the knowledge of those skilled in the art, and furthermore, such embodiments include: It goes without saying that any of these methods fall within the scope of the present invention as long as they do not depart from the spirit of the present invention.
