Description

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

  Conventionally, contact lenses (hereinafter referred to as CL) are stored by being immersed in a liquid contained in a container except during wearing. The CL is subjected to actions (processing) such as cleaning, disinfection, improvement of surface wettability and the like by a dedicated liquid agent contained in the container, and functions as a lens until the next wearing. Maintenance and recovery are being carried out.

  By the way, when storing the 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 the storage, thereby stably Further, in order to hold the lens storage chamber so as not to be scratched, a holder provided with a lens storage chamber is used, and the CL is stored in the lens storage chamber so that it can be immersed in the liquid in the container. However, in particular, among the CL, in a soft contact lens (hereinafter referred to as SCL) that has low rigidity and is easily deformed, various studies have been made on a holder for holding the lens. As for U.S. Pat. No. 3,770,113, EP Publication No. 2409595, Utility Model Registration No. 3193895, etc., there is one form thereof. It has been revealed.

  That is, all of the holders proposed in the specification or the publication are overlapped so as to cover the lens pedestal portion having a spherical surface or a dome-shaped surface on which the SCL is placed. A spherical lens housing portion corresponding to the lens shape is formed while forming a predetermined gap between them by overlapping the lens pedestal portion and the spherical lid portion. The target SCL is accommodated therein, and is immersed in the liquid accommodated in the container.

  However, in the conventional lens holder as described above, a plurality of liquid passage holes having large openings are formed in the rounded lid portion forming the lens storage chamber so as to penetrate the inner and outer surfaces. It is provided so that liquid can freely flow into and out of the lens storage chamber. On the surface of the dome-shaped lens base portion on which the SCL is placed, a large number of slits and liquid passage holes are provided. The SCL housed in the lens housing chamber when the holder having such a structure is pulled out of the liquid in the container and taken out of the container is used as the lens housing. Adhering to the inner surface of the round lid-shaped lid that forms the chamber, or adhering to the surface of the dome-shaped lens pedestal, it always adheres securely to the surface of the lens pedestal Without that Than it was not capable of stably removed from a lens storage chamber to SCL.

  Then, when the SCL stored in such a lens storage chamber removes the lens holder from the storage container and opens or opens the rounded lid-shaped lid portion and the dome-shaped lens pedestal portion, this is taken. If the SCL is attached to the inner surface of the round lid, the wearer's finger touches the rear surface (inner surface) of the SCL when wearing such an SCL with a finger. In addition to the problem that finger dirt and bacteria adhere to the inner surface of the SCL, there is a risk of scratching the inner surface of the SCL with the fingernail.

U.S. Pat. No. 3,770,113 EP Publication No. 2409595 Utility Model Registration No. 3193385

  Here, the present invention has been made in the background as described above, and the problem to be solved thereof is to take out the lens holder from the storage case and use the holding member for wearing the SCL. To provide a storage case for SCL in which the SCL is always stably attached on the dome-shaped lens pedestal portion of the holding member when the cover member is opened. When the lens holder is pulled up from the liquid stored in the storage case, the SCL is taken out and worn, the finger does not touch the inner surface side of the SCL, and therefore, the finger dirt and bacteria adhere to the inner surface of the SCL. It is another object of the present invention to provide a storage case for SCL that can be worn safely without causing damage due to fingernails.

  In the present invention, in order to solve the above-described problems, a container body having a bottomed cylindrical shape in which a predetermined liquid is accommodated, and a container body detachably attached to the opening of the container body. A cap member capable of forming a sealed space inside the main body, and a lens holder that is attached to the inside of the cap member and extends so as to hang from the cap member, and includes a lens storage chamber in which an SCL is stored and held. In the storage case of the SCL, the lens holder is provided inside the cap member so as to be fixed in position, and is provided to be rotatable with respect to the holder body, and is smaller than the base curve of the SCL. A holding member having a radius of curvature and a smooth curved convex surface and having a dome-shaped lens pedestal portion on which the SCL is placed, and the holding member overlapped with the holding member The lens storage chamber is formed on the lens pedestal portion, and a cover member provided with a liquid passage hole that allows the liquid to flow through the lens storage chamber forming portion but prevents the passage of the SCL. The gist of the storage case for SCL is configured to be inserted into the container main body and immersed in the liquid.

  According to one of the desirable embodiments of the storage case for SCL according to the present invention, the curved convex surface of the lens pedestal portion of the holding member is a mirror surface, whereby the features of the present invention are more advantageously exhibited. The Rukoto.

  Moreover, according to the other desirable aspect of this invention, the said cover member is provided so that rotation with respect to the said holder member is possible.

  Furthermore, in the present invention, the holding member, the cover member, and the holder main body are formed of an integral resin molded product, and between the holding member and the holder main body and between the cover member and the holder main body. Are connected by a thin-walled portion to constitute a hinge portion.

  According to another preferred embodiment of the storage case for SCL according to the present invention, a claw portion is provided on one of the holding member and the cover member, and the claw portion is provided on either one of them. An engaging portion that can be engaged with each other is provided, and the overlapping state of the holding member and the cover member is held by the engagement between the claw portion and the engaging portion.

  In the present invention, it is desirable that an engagement protrusion is provided on a portion of the holding member opposite to the cover member facing side, and the cap member is rotated to rotate the cap member. By reaching the end of the container main body, the engaging projection engages with the inner peripheral portion of the end, and the holding member can be locked to the cap member. .

  Further, according to another preferred embodiment of the present invention, the cover member is a flat bottom cylindrical portion having a size sufficient to accommodate the lens pedestal portion at a portion of the holding member facing the lens pedestal portion. And the liquid passage hole is provided in a flat bottom portion of the flat bottom cylindrical portion, and the lens storage chamber is formed by overlapping the flat bottom cylindrical portion on the lens pedestal portion. Yes.

  In the present invention, it is desirable that the container main body has a flat cross-sectional shape including at least the bottom thereof and has a structure that can be placed horizontally, whereby the stability of the storage case for SCL is improved. As a result, the convenience of the user can be improved, and the amount of the liquid that is accommodated in the container body and in which the SCL held in the lens holder is immersed can be advantageously saved.

  Thus, in the SCL storage case according to the present invention, the dome-shaped lens pedestal portion on which the SCL is placed in the holding member constituting the lens holder has a smaller radius of curvature than the SCL base curve. In addition, the SCL is provided with a liquid passage hole when the overlapped cover member and holding member are opened (opened) from a surface having a smooth curved convex surface. Since it adheres with a larger adhesive force to the smooth curved convex surface of the dome-shaped lens base portion of the holding member than to the inner surface of the cover member, this allows the SCL to be removed from the storage case. , SCL can be more stably held on the smooth curved convex surface of the dome-shaped lens base portion of the holding member, and is advantageously separated from the cover member.

  Therefore, the SCL attached and held on the smooth curved convex surface of the dome-shaped lens pedestal portion of such a holding member should be taken out and worn on the eye by touching the lens outer surface with a finger without touching the lens inner surface. In addition to being able to effectively avoid the problem of attaching dirt and bacteria on the inner surface of the lens and bringing it into the eye, the fingernails of the wearer's fingertips The problem of damaging the inner surface of the lens can be avoided.

  In addition, since the smooth curved convex surface of the dome-shaped lens pedestal portion is not provided with any opening holes or slits, the problem of adhesion of dirt and the propagation of bacteria can be advantageously prevented. In particular, such a feature can be exhibited even more advantageously when the curved convex surface is a mirror surface. Furthermore, the adoption of such a mirror surface can be applied to the curved convex surface of the SCL. The adhesion can be further increased.

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

  First, FIG. 1 schematically shows a front view and a longitudinal sectional view of an example of a storage case for SCL according to the present invention. In this case, the SCL storage case 10 is attached to the bottomed cylindrical container main body 12 in which a predetermined liquid is stored, and to the opening of the container main body 12 in a liquid-tight and detachable manner by screwing, A cap 14 that can form a sealed space inside the container body 12 and a lens holder 16 that is attached to the inside of the cap 14 and extends so as to hang down from the cap 14 are inserted into the container body 12. Further, in such a lens holder 16, the left and right SCLs 18 and 18 are respectively stored and two lens storage chambers 20 and 20 are formed so as to be adjacent to each other in the longitudinal direction of the lens holder 16. Has been. In addition, the liquid stored in the container main body 12 may be used as it is, as is the case with conventional liquids that act on the immersed SCL 18 such as cleaning, disinfection, and improvement of surface wettability. Become.

  Then, the SCL 18 held in the SCL storage case 10 is taken out after being pulled up from the immersion liquid by unscrewing the cap 14 from the container body 12 as shown in FIG. It becomes. Specifically, after the cap 14 to which the lens holder 16 is attached is removed from the container body 12, the upper surface of the cap 14 is lowered with respect to an appropriate placement surface as shown in FIG. Then, the lens holder 16 is placed so as to stand upright, and the holding member 22 and the cover member 24 constituting the lens holder 16 are overlapped as shown in FIG. When the state is released and the lens storage chambers 20 are opened, the left and right SCLs 18 and 18 are taken out from the respective lens storage chambers 20.

  By the way, as shown in FIGS. 4 (a) to 4 (e), the container body 12 constituting the SCL housing case 10 as described above has a corner portion except for the opening portion into which the cap 14 is screwed. It has a rectangular flat cross-sectional shape as a curved portion, and is formed in an arcuate shape in which the central portion in the height direction is recessed most inside the cylinder, and further, on the outer periphery of the opening, An outer screw portion 12a for screwing is formed. An internal space 26 similar to the outer shape of the container body 12 is formed inside the container body 12. In addition, such a container main body 12 is obtained by molding in the same manner as before using a known resin material such as polyethylene, polypropylene, and polycarbonate.

  Further, the cap 14 that is screwed into the outer threaded portion 12a on the outer periphery of the upper opening of the container body 12 and closes the upper opening is formed in a disk shape as shown in FIGS. 5 (a) to 5 (c). The outer peripheral cylindrical portion 14b is suspended from the outer peripheral portion of the top plate portion 14a by a predetermined height, and the inner screw portion 14c provided on the inner peripheral surface of the outer peripheral cylindrical portion 14b is an outer peripheral portion of the upper opening of the container body 12. The upper opening portion of the container main body 12 can be liquid-tightly closed by being screwed to the outer screw portion 12a provided in the container. Further, a fitting cylinder portion 28 is integrally provided at the center of the inner surface (lower surface) of the top plate portion 14a of the cap 14 at substantially the same height as the outer circumferential cylinder portion 14b. An appropriate number (three in this case) of ring-shaped recesses 28a are provided on the inner peripheral surface of the portion 28 at a predetermined distance in the axial direction. Then, a holder body of a lens holder 16 described later is fitted and fixed to the fitting cylinder portion 28 provided on the cap 14, so that the inner side of the cap 14 is shown in FIGS. 1 to 3. The lens holder 16 is attached in an upright configuration. Note that the cap 14 is also formed of a resin molded product, similar to the container body 12.

  Further, together with the container body 12 and the cap 14 described above, the lens holder 16 that constitutes the SCL storage case 10 and holds the SCL 18 to be stored includes a holding member 22 and a cover lid as shown in FIG. While the member 24 is configured to be folded and overlapped, the holding member 22 and the cover member 24 are expanded 180 degrees as shown in FIG. It is configured in a structure that can take a form free from the form formed.

  Specifically, as shown in FIGS. 7A to 7E, the lens holder 16 has thin hinge portions on both sides of the holder main body 30 attached to the fitting cylinder portion 28 of the cap 14. The holding member 22 and the cover member 24 have a structure in which the holding member 22 and the cover member 24 are integrally connected to each other via 32 and 32, respectively. It is composed of a resin molded product. In this case, the holder body 30 includes a rectangular plate-shaped base plate 30a having hinges 32, 32 formed on corresponding side portions, and a mounting cylinder portion 30b having a predetermined length integrally formed at the center of the lower surface thereof. In addition, an appropriate number (three in this case) of ring-shaped convex portions 30c are formed on the outer peripheral surface of the mounting cylinder portion 30b at a predetermined interval in the axial direction. Then, as shown in FIG. 1 (b), this mounting cylinder part 30 b is fitted into a fitting cylinder part 28 provided on the inner surface of the cap 14, and these ring-shaped convex parts 30 c are inside the fitting cylinder part 28. By being fitted into the ring-shaped recess 28a on the peripheral surface, the position is held fixed, so that the holder main body 30 and thus the entire lens holder 16 is fitted into the fitting tube portion 28, and thus the mounting tube portion 30b. It is held so as to be freely rotatable around the axis of the.

  The holding member 22 includes a long flat plate-like base plate, and one end portion of the holding member 22 is connected to one of opposing side portions of the holder body 30 via a thin hinge portion 32 so as to be integrated. It is structured. The holding member 22 is integrally formed with dome-shaped lens pedestals 34 and 34 for mounting the left and right SCLs 18 and 18 in the longitudinal direction of the base plate. The lens pedestals 34 and 34 each have a smaller radius of curvature than the base curve (rear curve) of the SCL 18 to be placed, and have no liquid passage holes, slits, or the like, and have a smooth curve without irregularities. It is configured to have a convex surface, whereby a larger surface tension or adhesion force can be generated with respect to the SCL placed.

  In particular, the curved convex surface of the dome-shaped lens pedestal portion 34 is a mirror surface here in order to make the SCL 18 adhere more reliably. As described above, in the present invention, it is desirable that the curved convex surface be a mirror surface. However, such a mirror surface mirror-polishes the corresponding cavity surface of the mold when the holding member 22 is integrally formed. Thus, it is possible to easily give a similar mirror surface to the curved convex surface. Of course, after the holding member 22 is formed, the curved convex surface of the dome-shaped lens pedestal 34 can be mirror-finished by mirror polishing or the like to make it into a mirror surface. It is possible to achieve a mirror surface.

  In addition, the curvature radius of the smooth curved convex surface of the dome-shaped lens pedestal 34 is appropriately selected at a curvature radius smaller than the base curve of the SCL 18 placed thereon, In particular, the radius of curvature of the base curve of the SCL 18 is about 70% or more, preferably about 80 to 90%, specifically selected within the range of 5 mm to 8 mm. A curvature radius of 7.5 mm is employed.

  At the tip of the holding member 22, a key-shaped locking piece 36 constituting a lock mechanism for holding the overlapped state with the cover member 24 rises from the plate-like portion of the holding member 22. Are integrally provided. Further, two engaging projections 38 are provided on a portion (surface) of the holding member 22 on the side opposite to the side facing the cover member 24 of the plate-like portion (base), as shown in FIG. As shown, the holding member 22 is rotated so as to fall down in the horizontal direction, whereby the engaging protrusion 38 is engaged with the inner peripheral portion of the cap 14, and the holding member 22 is engaged with the cap 14. It can be stopped.

  A circular wall 35 having a low height for forming the lens storage chamber 20 is provided around each of the dome-shaped lens pedestals 34 and 34 so as to surround them. The walls 35 and 35 are connected to each other.

  On the other hand, as is clear from FIGS. 7A to 7E, the cover member 24 has a diameter corresponding to the circular wall 35 formed in the holding member 22 with respect to the long flat plate-like base plate. Two of the flat bottom cylindrical portions 40 are provided in a row, and when the cover member 24 and the holding member 22 are rotated and overlapped at the portions of the hinge portions 32 and 32, respectively, The flat bottom cylindrical portion 40 is disposed so as to be located at a portion facing the dome-shaped lens pedestal portion 34 of the holding member 22 and with a size sufficient to accommodate the dome-shaped lens pedestal portion 34. .

  In addition, as apparent from FIGS. 6A and 7A, the flat bottom portion of the flat bottom cylindrical portion 40 has a relatively large central hole 42a and a peripheral shape having a fan-shaped trapezoidal shape located therearound. A liquid passage hole 42 consisting of six holes 42b is provided, the holding member 22 and the cover member 24 are overlapped, and the circular wall 35 and the flat bottom cylindrical portion 40 of the SCL 18 therebetween. In order to avoid pinching, they are arranged to face each other with a predetermined gap (about 0.1 to 1 mm). Then, the liquid stored in the container body 12 can freely flow in and out through the liquid passage hole 42 with respect to the lens storage chamber 20 shown in FIG. It has become. In addition, the size of the liquid passage hole 42 (42a, 42b) is set so that the SCL 18 stored and held in the lens storage chamber 20 does not escape to the outside. The gap at the butted portion with the cylindrical portion 40 is also a gap that can prevent such SCL 18 from passing therethrough.

  Further, a claw portion 44 is provided at the distal end portion of the cover member 24, in other words, at a portion opposite to the holder main body 30 connection side, as shown in an enlarged view in FIG. When the cover member 24 and the holding member 22 are rotated and overlapped as shown in FIG. 6A, the claw portion 44 is provided at the tip of the holding member 22. A locking mechanism is configured to engage with the stopper piece 36 and hold the cover member 24 and the holding member 22 in an overlapped state as shown in the figure.

  Accordingly, in the SCL storage case 10 having such a configuration, when the SCL 18 stored and held therein is taken out for wearing, the cap 14 is rotated with respect to the container main body 12 to rotate the cap 14. After the cap 14 is taken out together with the lens holder 16 attached thereto as shown in FIG. 2, as shown in FIGS. 3 (a) and 3 (b), the lens holder 16 is made upright. The cap 14 is placed so that the upper surface of the cap 14 faces down, and the engagement between the locking piece 36 and the claw portion 44 constituting the locking mechanism is released, and the holding member 22 and the cover member 24 are When the hinges 32 and 32 are rotated, their overlapping form is released, and the lens storage chamber 20 is opened. At that time, the SCL 18 accommodated therein is provided with a liquid passage hole, a slit, or the like in the dome-shaped lens base portion 34 of the holding member 22 rather than the flat bottom cylindrical portion 40 that forms the lens housing chamber 20. The SCL 18 is configured as a lens pedestal portion having a curved convex surface having a curvature radius smaller than the base curve of the SCL 18 and the SCL 18 is surely and stable. Therefore, it comes to adhere to the dome-shaped lens pedestal 34 side.

  Then, as shown in FIG. 3B, the SCL 18 attached on the dome-shaped lens pedestal 34 in the state where the holding member 22 is rotated and positioned in the horizontal direction is shown in FIG. As shown in FIG. 4, the lens outer surface can be easily taken out by gently picking the outer surface of the lens with a fingertip and can be worn on the target eye. (Inner surface) is not touched by the finger, so the lens rear surface is not contaminated by dirt or bacteria attached to the finger, and it can be worn and can be worn with the fingernail. The problem of damaging the rear surface of the lens can also be solved.

  Moreover, since the dome-shaped lens pedestal portion 34 of the holding member 22 on which the SCL 18 is placed has a smooth curved convex surface that does not have an opening hole, a slit or the like, adhesion of dirt and bacterial growth are effective. Therefore, the characteristics that can further improve the safety or cleanliness during storage and holding of the SCL 18 are exhibited. In particular, such an action or effect can be exhibited even more advantageously when the curved convex surface of the dome-shaped lens pedestal 34 is a mirror surface.

  Here, as shown in FIG. 3B, when the holding member 22 is rotated and tilted in the horizontal direction, the back side of the base plate of the holding member 22, in other words, the side opposite to the cover member 24. Since the two engaging projections 38, 38 are provided on the opposite side of the engaging projections 38, 38 as shown in FIG. 9 (however, here, the holding member 22 is The outline is shown as an imaginary line, and only the two engaging protrusions 38, 38 are shown by solid lines.), And is engaged with the inner peripheral surface of the opening of the outer peripheral cylindrical portion 14b of the cap 14. The posture can be maintained. Therefore, it is possible to make a large opening gap with the cover member 24, so that the operability in taking out and placing the SCL 18 with respect to the dome-shaped lens base portion 34 is further advantageously improved. It was to get.

  Further, in the SCL storage case 10 as described above, as is apparent from FIGS. 2 and 4, the container body 12 has a flat cross-sectional shape in a rounded rectangular shape at least at the bottom thereof. As shown in FIG. 1, the container body 12 is placed upright and placed in a vertical orientation in which the container body 12 is placed in the vertical direction. In addition, as shown in FIG. It is also possible to place it in a horizontally placed form, whereby the stability of the SCL storage case 10 can be improved, the convenience of the user can be advantageously increased, and the SCL 18 should be immersed. There is an advantage that the amount of liquid contained in the container body 12 can be advantageously reduced. However, since the SCL storage case 10 has a flat cross-sectional shape including at least its bottom as shown in the container main body 12, as compared with the case where a circular cross-sectional shape is adopted, The amount of liquid stored in the container body 12 can be advantageously reduced.

  By the way, when storing and holding the SCL 18 in the SCL storage case 10 as described above, a process opposite to the above-described case of taking out the SCL 18 is employed. For example, as shown in FIG. In this embodiment, the left and right SCLs 18 and 18 removed from the wearer's eyes are placed on the curved convex surface of the dome-shaped lens pedestal 34 in the form in which the holding member 22 is tilted horizontally. 22 and the cover member 24 are rotated so that they are overlapped as shown in FIG. 3A, and the claw portion 44 is engaged with the locking piece 36, so that the overlapped state is achieved. After locking, the lens holder 16 portion composed of the holding member 22 and the cover member 24 overlapped with each other is inserted into the container body 12 and immersed in a predetermined liquid. It is in the form comprising, so that the holding or until the next worn opportunities are saved.

  Then, when the SCL 18 is housed in the lens housing chamber 20 formed by superimposing the holding member 22 and the cover member 24 in the lens holder 16 in this way, when immersed in the liquid in the container body 12. The SCL 18 placed on the dome-shaped lens pedestal 34 has a curved radius of curvature of the lens pedestal 34 that is smaller than the base curve of the SCL 18. There is sufficient clearance for the SCL 18 to pass therethrough, so that the liquid will sufficiently circulate on the rear surface (inner surface) of the SCL 18, and the SCL 18 will float and float in the lens storage chamber 20. Thus, the SCL 18 is sufficiently subjected to the action of the liquid contained in the container body 12 on both the inner and outer surfaces thereof, Example, cleaning, disinfecting, and than so that the process of improvement of surface wettability can be effectively performed.

  The exemplary embodiments of the present invention have been described in detail above, but these are merely examples, and the present invention is not limited in any way by specific descriptions according to such embodiments. It should be understood that this is not to be interpreted.

  For example, in the above embodiment, the two engaging protrusions 38, 38 provided on the back portion of the holding member 22 are provided for improving the operability, but the number thereof is appropriately selected. However, there may be one or three or more, and it is also possible to adopt a structure in which such an engagement protrusion 38 is not provided.

  Further, in order to enable the holding member 22 and the cover member 24 to rotate, here, the holding member 22 and the cover member 24 are integrated with the holder main body 30 by thin hinge portions 32 and 32. Although a structure connected to the head is adopted, various types of conventionally known rotating structures, for example, a holder member and a cover member are pivotally attached to the holder body so that the holder can be rotated. It is possible to arbitrarily adopt the structure and the like. The rotation of the cover member 24 is desirable from the viewpoint of operability, but does not necessarily have to be a rotatable structure.

  Further, the circular wall 35 provided around the dome-shaped lens pedestal portion 34 of the holding member 22 has the SCL 18 placed on the dome-shaped lens pedestal portion 34, and the cover member 24 is overlaid thereon, and the flat bottom cylindrical portion 40. However, when the lens storage chamber 20 is formed, the holding member 22 is flat without providing such a circular wall 35. Even if the lens storage chamber 20 is formed by placing the flat bottom cylindrical portion 40 of the cover member 24 on the plate surface, there is no problem.

  In addition, of course, the container main body 12 can have a general cylindrical shape in addition to the flat cross-sectional shape as illustrated.
