Description

The present invention relates to a storage case for hard contact lenses, and more particularly to a storage case capable of advantageously storing and holding various hard contact lenses of different sizes.

Conventionally, contact lenses (hereinafter referred to as CL) are immersed in a liquid contained in a container and stored except during wearing. Then, in such a container, CL is subjected to actions (treatments) such as cleaning, disinfection, and improvement of surface wettability by a special liquid agent contained therein, and functions as a lens until the next wearing. Is being maintained and restored.

By the way, when accommodating the target CL in such a storage container, the CL can be easily taken out from the storage container, and the movement of the CL in the container is restricted during storage. In order to hold the lens stably and without scratches, a holder provided with a lens storage portion is used, and the CL is stored in the lens storage portion so that the CL can be immersed in the liquid in the container. However, in particular, even in CL, even if it is a hard contact lens (hereinafter referred to as HCl) that is relatively rigid and has good shape retention, various proposals have been made for a holder that holds it. For example, with respect to the lens storage portion in which HCl is stored, one form thereof is clarified in Practical New Design Registration No. 2512458, Practical New Design Registration No. 3193886, and the like.

That is, each of the holders in the storage container proposed in those publications is provided with a pair of holding arms having an opening groove in which a peripheral edge portion corresponding to the radial direction of HCl is inserted and held so as to face each other. , So-called tulip shape or square tube shape, and the HCL gripped by two fingers is pushed in so as to widen the gap between the tips of the pair of holding arms, and the pair thereof. HCL is stored and held between the holding arms of the container, and in that state, it is immersed in the liquid contained in the container. In addition, when wearing such HCL, the HCL is taken out by pulling it out so that the gap between the pair of holding arms is widened while the HCL is being held by two fingers, and the HCL is taken out to the target eye. It is designed to be worn.

However, in the lens holder in such a conventional storage container, the slits (gap) formed between the corresponding wall portions of the pair of holding arms are, in other words, on both sides of the pair of holding arms. A pair of small size (small diameter) HCl is formed in a direction perpendicular to the opposite direction of the pair of holding arms, respectively, in a form extending linearly with a predetermined width in the standing direction of the holding arms. When the HCL is stored in the lens housing provided between the holding arms, the movable range of the small-diameter HCL in the lens housing becomes large, and therefore, when rinsing the HCL with running water, the HCL holds a pair of sandwiches. It causes a problem that it slips out of the slits provided on both sides of the arm and falls off to the outside.

Therefore, in order to store and hold the commonly used HCl having a lens diameter of about 8 to 11 mm, it is necessary to prepare a plurality of lens holders having different sizes of the lens storage portions, thereby costing the lens holder. In addition to causing the lens to rise, it is necessary to make a troublesome judgment of selecting the lens holder according to the size of the HCl, and there is a possibility that the wrong selection of the lens holder may cause troubles such as dropping of the HCl. It was something to do.

Utility Model Registration No. 2512458 Utility Model Registration No. 3193886

Here, the present invention has been made in the context of such circumstances, and the problem to be solved thereof is a lens capable of advantageously accommodating and holding HCl of various sizes having different lens diameters. To provide a storage case for hard contact lenses equipped with a holder, and another issue is that one lens holder has a very wide range of standard lens diameters from 7.6 mm to 11.5 mm. The purpose of the present invention is to provide a storage case for HCL corresponding to HCL.

The present invention can be preferably carried out in various aspects as listed below in order to solve the above-mentioned problems, and each of the following aspects is adopted in any combination. It is possible. It should be noted that the aspects or technical features of the present invention are not limited to those described below, and can be recognized based on the invention idea disclosed in the description and drawings of the entire specification. Should be understood.

Therefore, in the present invention, first, in order to solve the above-mentioned problems, (a) a bottomed tubular container body in which a predetermined liquid is stored and (b) an opening of the container body can be attached and detached. A cap member that is attached to the lens body and can form a closed space inside the container body, and (c) is fixed inside the cap member and extends so as to hang down from the cap member, and the inside of the container body. A lens holder having a lens holder for storing and holding the HCL, which is inserted into the lens holder, has an opening groove having a U-shaped cross section at least on the tip side portion of the lens holder. A pair of arm portions that are formed and hung so that the openings of the opening grooves face each other and support both radial portions of the HCL are provided, and the tips of the pair of arm portions are widened. The lens accommodating portion for accommodating and holding the HCL that has been inserted into each opening groove is formed between the pair of arm portions, and both side walls of the opening groove in the lens accommodating portion of the pair of arm portions. However, between the corresponding side walls of the pair of arm portions, a non-linear slit of a predetermined gap is formed so as to extend in the hanging direction of the pair of arm portions, and both side walls of the opening grooves are formed. The gist of the present invention is a storage case for an HCL, which is characterized in that two non-linear slits formed between the corresponding objects of the lens are arranged so as to be asymmetrical.

According to one of the preferred embodiments of the HCl storage case according to the present invention, the non-linear slit is formed so as to extend in the vertical direction of the pair of arm portions in a curved corrugated shape. Will be adopted.

Further, according to another one of the more preferable aspects of the storage case for HCl according to the present invention, the cap member and the lens holder are integrally molded with a resin molded product.

Further, according to one of the desirable alternative aspects of the HCL storage case according to the present invention, the lens holder exhibits a square tube shape having a predetermined thickness, which provides a lens storage portion for storing and holding the left and right HCl, respectively. In the structure, the main surfaces of the square cylinder shape are arranged in a double manner so as to be parallel to each other.

Then, in the present invention, preferably, in a configuration in which the lens holders have a double structure, the double lens holders face each other and are positioned in the thickness direction of the lens holders with a predetermined gap. In addition to being fixed to the inner surface of the top plate portion of the cap member, the periphery of each fixed portion of the two lens holders with respect to the top plate portion of the cap member is formed as a thin-walled portion. The thin-walled portion located between the fixed portions of the lens holder is configured as the central hinge portion, while the thin-walled portions on both sides located on the outer side in the opposite direction of the two lens holders are the outer hinge portions, respectively. In the central hinge portion and the two outer hinge portions, the fixed portion of the double lens holder is a chevron-shaped indentation portion having the central hinge portion as the apex and protruding outward. By pushing the cap member inward, the hinged portion reverses the pushed portion, and the pushed portion becomes a chevron shape that protrudes inward of the cap member. The lens holder is configured so as to be displaced from the top plate portion of the cap member in a V-shaped opening.

As described above, in the storage case for HCL according to the present invention, the slits (gap) formed between the corresponding side walls forming the lens storage portion in the pair of arm portions constituting the lens holder have a non-linear shape. In addition to being formed so as to extend in the hanging or erection direction of the pair of arm portions, the respective non-linear slits are formed on both side portions in the direction perpendicular to the opposite direction of the pair of arm portions. Since the structure is arranged so as to be asymmetric with each other, the lens can be stored not only in the HCL with a large lens diameter but also in the HCL with a small lens diameter when rinsing with running water. Even if the HCL held in the portion can be moved in all directions, there is no possibility that the HCL will fall out of the slits formed on both sides of the pair of arm portions, whereby one The lens holder can support a very wide standard of HCL with a lens diameter of 7.6 mm to 11.5 mm, and thus the number of lens holders to be prepared can be effectively reduced. In addition to being able to effectively reduce the cost of the lens holder and the cost as a storage case for HCL, there is no need to select a lens holder according to the size of the HCL. The complexity of the selection has been eliminated, and the occurrence of troubles due to this has been effectively eliminated.

In particular, in the present invention, the non-linear slits formed between the corresponding side walls of the pair of arm portions are formed so as to extend in the hanging direction of the pair of arm portions in a curved corrugated shape. By adopting a configuration that is squeezed, it is possible to prevent the HCL from coming out of the lens housing more effectively, and at the same time, it is possible to further prevent such HCL from being stored in the lens storage and being taken out from it. There is an advantage that it can be easily and smoothly performed, and by using a resin molded product in which the cap member and the lens holder are integrally molded, the number of parts can be effectively reduced. It is also possible to advantageously reduce the manufacturing cost.

Hereinafter, in order to clarify the configuration of the present invention in more detail, typical embodiments of the present invention will be described in detail with reference to the drawings.

First, FIGS. 1 (a) to 1 (d) and FIGS. 2 (a) and 2 (b) show an example of a storage case for HCL according to the present invention. There, the storage case 10 for HCL is liquid-tight and removable by screwing into a transparent container body 12 having a bottomed cylinder shape in which a predetermined liquid agent is stored and an upper opening of the container body 12. A cap 14 that is attached and can form a closed space inside the container body 12 and is inserted into the container body 12 that is fixed inside the cap 14 and extends so as to hang down from the cap 14. It is composed of a lens holder 16. Further, as is clear from FIG. 2B and the like, the lens holder 16 has a square tube shape having a predetermined thickness as a whole, and the two lens holders 16 face each other with their main surfaces facing each other and are parallel to each other. It is provided in a double structure in the form of being arranged. Then, as will be described later, the two lens holders 16 and 16 have lens storage portions 20 and 20 for storing and holding the HCLs 18 and 18 on the left and right sides (for the left eye and the right eye) of the wearer, respectively. , Is being formed. As the liquid agent contained in the container body 12, the same liquid agent as the conventional one, which has actions such as cleaning, disinfecting, and improving the surface wettability, is used as it is for the HCL18 to be immersed. Become.

Here, the container body 12 constituting the HCL storage case 10 described above has a dodecagonal outer peripheral surface excluding the upper opening portion to which the cap 14 is screwed, and is formed on the outer periphery of the upper opening portion. Is formed with an outer threaded portion for screwing the cap 14. Further, inside the container body 12, a circular internal space 22 for accommodating a predetermined liquid is formed. Such a container body 12 is obtained by molding using a known resin material such as polyethylene, polypropylene, or polycarbonate in the same manner as in the conventional case.

Further, the cap 14 that is screwed into the outer threaded portion on the outer periphery of the upper opening of the container body 12 to close the upper opening is shown in FIGS. 2 (b) and 3 (a) to 3 (c). As described above, it has an outer peripheral cylinder portion 14b having a dodecagonal outer peripheral surface that hangs down from the outer peripheral portion of the top plate portion 14a at a predetermined height, and is provided on the inner peripheral surface of the outer peripheral cylinder portion 14b. The inner threaded portion is screwed into the outer threaded portion provided on the outer peripheral portion of the upper opening of the container body 12, so that the upper opening in the container body 12 is liquid-tightly closed. .. Then, on the top plate portion 14a of the cap 14, a double lens extending so as to be located on both sides of a virtual line extending in the radial direction through the center of the inner surface (lower surface) thereof and extending so as to face each other over a predetermined length. Lens holders 16 and 16 are integrally provided in a square cylinder shape having a predetermined thickness. Further, the two lens holders 16 and 16 are configured so as to be erected inside the cap 14 so as to hang down from the top plate portion 14a in parallel with each other by a predetermined length. The cap 14 and the lens holder 16 are made of an integrally resin molded product obtained by an integral molding operation using the same resin as the container body 12, thereby reducing the number of parts and eventually reducing the number of parts. Effective reduction of manufacturing cost is achieved. In particular, as will be described later, since the lens holder 16 needs to be easily expanded and deformed in order to put in and take out the HCL 18, as a resin constituting the cap 14 and the lens holder 16. It is desirable that the lens has a certain degree of flexibility, and polypropylene is particularly preferably used.

The lens holders 16 and 16 having a square tubular shape, which are integrally formed on the inner surface of the top plate portion 14a of the cap 14, are shown in FIGS. 3 (a) to 3 (c), respectively. And, as shown in FIGS. A pair of arm portions 24, 26 having a width are provided, and the pair of arm portions 24, 26 are connected to each other and integrated at the base portion on the top plate portion 14a side, and the inner surface of the top plate portion 14a is integrated. It is erected integrally with the lens. As is clear from FIGS. 1 (c) and 2 (a), the left and right sides of the top plate portion 14a of the cap 14 should be stored at positions corresponding to the two lens holders 16 and 16, respectively. The symbols "L" and "R" indicating HCL18, 18 of the above are formed in the relief structure. Further, there, the pair of arm portions 24, 26 are provided with side walls 24a, 24b; 26a, 26b having predetermined heights at both ends in the width direction thereof, and their side wall 24a, 24b; 26a, 26b, respectively. Since the opening grooves 24c and 26c are formed between them, and the pair of arm portions 24 and 26 are erected so that the openings of the opening grooves 24c and 26c face each other. be.

Further, windows 24d and 26d are provided on the back of the tip side portions of the arm portions 24 and 26, and both side walls are provided on the inner surface of the arm portion tip side portion than the window portions 24d and 26d. A stopper portion 28a on the tip end side of an arcuate cross section is provided so as to connect 24a and 24b; 26a and 26b, respectively. On the other hand, the base side stopper portion 28b having a cross-sectional shape is provided with an arcuate concave surface so as to connect both side walls 24a, 24b; 26a, 26b to the inner surface of the arm portion base side portion rather than the window portions 24d, 26d. However, each is formed. Then, the space between the pair of arm portions 24, 26 surrounded by the tip side stopper portions 28a, 28a and the base side stopper portions 28b, 28b in the tip side portions of the pair of arm portions 24, 26 is the lens storage. It is formed as a part 20. The gaps between the tip side stoppers 28a and 28a located around the lens storage portion 20, the sizes of the window portions 24d and 26d, and the gaps between the base side stopper portions 28b and 28b are all lens storages. Of course, it is smaller than the lens diameter of the smallest size HCL18 housed and held in the portion 20. Further, both side walls 24a, 24b; 26a, 26b located on the base side of the pair of arm portions 24, 26 are largely cut out, and between the corresponding side walls 24a, 26a and the side wall 24b of the pair of arm portions 24, 26. Fingertip insertion window portions 27a and 27b for taking out the lens are formed between the and 26b, respectively.

In addition, in the lens holder 16 composed of the pair of arm portions 24 and 26 as described above, the lens storage of the pair of arm portions 24 and 26 is as shown in FIGS. 3 and 4. The side walls 24a, 24b; 26a, 26b of the opening grooves 24c, 26c in the portion 20 have a predetermined gap between the corresponding side walls 24a, 26a and the side walls 24b, 26b in the pair of arm portions 24, 26, respectively. The linear (here, curved corrugated shape) slits 30a and 30b are formed so as to extend in the hanging (erection) direction of the pair of arm portions 24 and 26. Moreover, the two non-linear slits 30a, 30b formed between the corresponding ones of the side walls 24a, 24b; 26a, 26b of the opening grooves 24c, 26c form the arm portion 24 or 26 constituting the lens holder 16. It is arranged so as to be asymmetric in the opposite direction of the side walls 24a, 24b or 26a, 26b in, in other words, in FIGS. 5 (a) and 5 (c), so as to be asymmetric in the direction perpendicular to the paper surface. There is. The widths of the two non-linear slits 30a and 30b are generally the same as the slit widths of the conventional lens holder, but the lens diameter ranges from 7.6 mm to 11.5 mm. In order to sufficiently prevent the HCL18 from coming out according to an extremely wide range of standards, a gap width of about 0.5 to 1.5 mm is advantageously adopted here.

As described above, in the HCL storage case 10 according to the present embodiment, each of the lens holders 16 provided in the dual structure is composed of a pair of arm portions 24 and 26, and a pair thereof. The portions of the side walls 24a, 24b; 26a, 26b of the opening grooves 24c, 26c of the arm portions 24, 26, which are located in the lens accommodating portion 20 formed between the arm portions 24, 26, correspond to each other. Non-linear slits 30a and 30b having a predetermined gap are formed between the side walls, and the non-linear slits 30a and 30b located on both sides thereof are opposed to the side walls 24a and 24b; 26a and 26b. By being arranged so as to be asymmetrical to the lens, the tips of the pair of arm portions 24 and 26 are widened so that the HCL18 can be inserted into the respective opening grooves 24c and 26c to accommodate the lens. In a state where the HCL 18 is stored and held in the unit 20, the HCL 18 does not come out of the lens housing 20 regardless of any movement.

That is, in FIGS. 5 (a) to 5 (c), the HCL18a having the largest lens diameter and the HCL18b having the smallest lens diameter in the standard having a lens diameter of 7.6 to 11.5 mm are paired with arm portions 24 and 26. A state in which the lens is housed in the lens storage part 20 formed between them is shown, in which the HCL18a having a large lens diameter does not move so much in the lens storage part 20. In the case of HCL18b having a small lens diameter, it is possible to move considerably in the lens housing portion 20, and even if such HCL18b having a small lens diameter moves significantly, the pair of arm portions 24 and 26 hang down. The slits 30a and 30b extending in the (erection) direction have a non-linear shape, and the slits 30a and 30b on both sides are configured to be asymmetrical, so that even in the HCL18b having a small lens diameter, It is possible to effectively prevent the slits 30a and 30b on both sides from coming out to the outside.

On the other hand, when the slits (30a, 30b) on both sides are provided linearly in the hanging direction of the arm portions 24, 26, the HCL18b having a small lens diameter comes out from such a linear slit. Further, even if the slits (30a, 30b) are arranged in a non-linear form, if the slits (30a, 30b) on both sides thereof are arranged symmetrically, the slits (30a, 30b) are arranged symmetrically. When the HCL18b having a small lens diameter takes various movement forms in the lens housing portion 20, the HCL18b may come out depending on the non-linear shape of the slit as well as the movement in the lens housing portion 20. There is.

By the way, in the lens holder 16 as described above, not only the HCL18a having a large lens diameter but also the HCL18b having a small lens diameter is formed between the pair of arm portions 24 and 26. Regardless of the size of the HCL18b, the HCL18 is held in such a lens holder 16 under running water or the like because it is stored inside, held securely, and does not come out to the outside. It is also possible to rinse, which can greatly improve the convenience of the HCL wearer.

Moreover, since the lens holder 16 according to the present embodiment is configured as an integrally resin molded product with the cap 14 in a form of integrally hanging from the top plate portion 14a of the cap 14, the cap 14 and the lens holder 16 As a single component, the number of components can be reduced, the productivity of the storage case 10 can be effectively increased, the assembling property can be effectively improved, and the manufacturing cost can be reduced. It will be possible to take advantage of it.

Further, as is clear from FIGS. 1 (c), 2 (a), (b), 3 (b), (c) and the like, the double lens holders 16 and 16 as described above are fixed to each other. The periphery of the portion is a thin portion, and the top plate portion 14a portion formed by the respective lens holders 16 and 16 cooperates to project outward or inward of the cap 14 in a chevron shape. A possible push-in portion 32 is formed. Specifically, an oval-shaped or oval-shaped outer groove portion 34 that opens to the outside of the cap 14 is formed so as to surround the formation portions of the double lens holders 16 and 16 on the top plate portion 14a of the cap 14. The bottom portion of the outer groove portion 34 constitutes a thin-walled portion, and the thin-walled portions provided by the portions of the outer groove portions 34 on both sides of the two lens holders 16 and 16 located on the outer sides in the opposite direction are provided. It constitutes the outer hinge portions 36, 36. Further, as shown in FIGS. 2 (b) and 3 (c), an inner groove 38 that opens inward of the cap 14 is located at a portion of the top plate 14a between the two lens holders 16 and 16. Is formed, and the thin portion of the top plate portion 14a provided by the inner groove portion 38 is configured as the central hinge portion 40. As shown in FIG. 5A, both ends of such a central hinge portion 40 are formed from the bottom portion of the inner groove portion 38, and the formed portions of the double lens holders 16 and 16 and the outer groove portion 34, respectively. It is designed to be continuously connected to the thin-walled portion formed between them.

Then, as shown in FIGS. 2 (b) and 6 (a), the two lens holders 16 and 16 are centered in a form in which their main planes are opposed to each other so as to be parallel to each other. While the cap 14 having the hinge portion 40 as the top is configured to form a chevron-shaped pushing portion 32 that is convex outward, as will be described later, the pushing operation of the pushing portion 32 inward of the cap 14 is performed. Due to the hinge action of the central hinge portion 40 and the outer hinge portions 36, 36, the push-in portion 32 is inverted, and as shown in FIG. 6B, it has a chevron shape that is convex inward of the cap 14. The lens holders 16 and 16 are expanded in a V shape from the base of the double lens holders 16 and 16, respectively. The operation of storing the left and right HCL18, 18 with respect to 16 and 16 and the operation of taking out the left and right HCL18 and 18 stored and held in the lens storage portions 20 and 20 of the lens holders 16 and 16 can be easily performed. It will be.

As described above, in the HCL storage case 10 according to the present embodiment, in order to realize the storage and holding structure of the left and right HCls 18 and 18 of the wearer in a compact structure, the lens holder 16 has a cap in a double structure. It is integrally arranged so as to hang down from the top plate portion 14a of 14, but in order to easily store and take out the left and right HCls 18 and 18 with respect to the lens holders 16 and 16 having such a dual structure. As shown in FIGS. 6A and 6B, the two lens holders 16 and 16 can be easily selected from the upright state and the expanded state with respect to the top plate portion 14a of the cap 14. It has become.

That is, as described above, the top plate portion 14a around the portion where the double lens holders 16 and 16 are arranged is formed as a thin portion, and the central hinge formed between the double lens holders 16 and 16 is further formed. As shown in FIG. 6A, the portions 40 and the two outer hinge portions 36, 36 provided on the outer sides of the two lens holders 16 and 16 in the opposite direction are formed on the outer side as shown in FIG. 6A. By pushing the convex chevron-shaped pushing portion 32 inward of the cap 14 with a thumb or the like, the central hinge portion 40 and the outer hinge portions 36, 36 on both sides thereof are hinged, as shown in FIG. 6 (b). As described above, the cap 14 is displaced inwardly into a chevron shape, whereby the double lens holders 16 and 16 are changed into a V-shaped expansion from the top plate portion 14a. It will be.

Then, in such a V-shaped expanded state, the left and right HCLs 18 and 18 are held by two fingers, respectively, and the tips of the pair of arm portions 24 and 26 of the respective lens holders 16 are pressed. The HCL18 is stored and held in the lens storage part 20 by expanding the HCL18, and the HCL18 stored and held in the lens storage part 20 is stored and held in the lens storage part 20 at the base of the pair of arm parts 24 and 26. The pair of arm portions 24, 26 are opened from the base side of the pair of arm portions 24, 26 by inserting the fingertips into the large fingertip insertion window portions 27a, 27b provided on both sides, while holding the HCL18. The HCL18 is taken out by moving the lens to the tip side of the lens 26. Therefore, such a storage operation and a removal operation of the HCL 18 can be easily performed without being interfered by the other lens holder 16 by expanding the double lens holders 16 and 16 in a V shape. The operation can be easily performed. Further, in the expanded state shown in FIG. 6B, after the HCL storage operation and removal operation are performed, the expanded lens holders 16 and 16 are brought closer to each other with a finger. By pressing or pinching, the state of FIG. 6 (a) can be easily returned, and in that state, the cap 14 is screwed into the container body 12, as shown in FIG. It will be treated as a storage case 10 for HCl in such a form.

In this way, in the storage and removal operations of the double lens holders 16 and 16 for storing and holding the left and right HCL18 and 18 in the HCL storage case 10, the chevron-shaped push-in portion formed on the top plate portion 14a of the cap 14 is formed. By simply pushing the 32 with a fingertip, the double lens holders 16 and 16 expand in a V shape, and the left and right HCL18 and 18 storage and removal operations interfere with each other by the other lens holder 16. This can be done easily and easily while avoiding it, which makes it possible to arrange the double lens holders 16 and 16 in close proximity to each other, and thus further to the whole HCL storage case 10. Compactness can also be easily realized.

Although the typical embodiments of the present invention have been described in detail above, they are merely examples, and the present invention is limited by specific descriptions relating to such embodiments. It should be understood that it is not interpreted.

For example, in the above-described embodiment, the cap 14 and the lens holder 16 are made of an integrally molded resin product, which contributes to the reduction of the number of parts. Of course, the cap 14 and the lens holder 16 It is also possible to construct a structure in which the lenses are made of separate parts, and they are integrally assembled by fitting or screwing to form a fixed structure.
