Description

The present invention relates to a contact lens storage container that accommodates and stores contact lenses, and more particularly to a disposable contact lens storage container that is discarded after the contact lenses are removed.

  As is well known, contact lenses that are repeatedly used over multiple days, such as hard contact lenses, soft contact lenses that are not disposable (so-called disposable), and soft contact lenses that are not disposable in a disposable type. Is stored in a storage container in a state of being immersed in a storage solution when stored after being removed from the eyeball such as at bedtime.

  By the way, the storage solution filled in the storage container needs to be replaced with a new storage solution every time the lens is accommodated (usually every day). However, some lens users store the storage solution in the storage container. It was sometimes used in the wrong way of continuously using the same preservative solution for several days or more in the state of being crushed. When the preservation solution is reused in this way, the antibacterial action of the preservation solution is gradually lowered, and the hygiene state in the preservation container is deteriorated. At the same time, when the lens is accommodated, there is also a problem that bacteria attached to the fingers enter the preservation solution due to the fingers entering the preservation solution.

  Furthermore, in recent years, even if the preservation solution is replaced every time, there is a concern that it may cause bacterial infection due to the biofilm generated in the preservation container. The biofilm is an aggregate in which bacteria are aggregated in a film shape. When such a biofilm is formed, the bacteria inside the biofilm are protected from the antibacterial agent and are difficult to sterilize. Therefore, when a biofilm is formed on the inner surface of a storage container for contact lenses, even if the storage container is filled with an antibacterial storage solution, bacteria protected by the biofilm adhere to the lens and extend. Has been shown to cause bacterial infection by entering the eyeball.

  Therefore, in order to solve such a problem, it has been studied to adopt a storage container that can be reused while preventing reuse as a contact lens storage container. That is, by disposing the storage container in a disposable manner and preventing reuse, a new aseptic storage container is provided every time the lens is stored to improve hygiene and before the biofilm is formed. By replacing it with a new storage container, it is intended to avoid the risk of bacterial infection caused by biofilm.

  As such a disposable contact lens storage container, for example, in Patent Document 1 (Japanese Patent Laid-Open No. 2002-142838), a sheet-like lid member is used as an adhesive or the like with respect to an opening of a housing portion that houses a contact lens. A structure having a structure in which re-sealing is impossible by sealing is proposed. However, in such a storage container, the shape of the accommodating portion is maintained regardless of the open / closed state of the lid member. Therefore, it is possible to repeatedly store the storage solution, which is still insufficient to prevent reuse.

  Patent Document 2 (Japanese Patent Laid-Open No. 2002-306227), Patent Document 3 (Japanese Patent Laid-Open No. 2004-121645), and Patent Document 4 (Japanese Patent Laid-Open No. 2005-296678) sandwich a bendable hinge portion. The container body and the lid member are integrally formed, and the lid member is superposed on the container body so that the hinge body is folded around the hinge body, and the engagement portion provided on the container body and the lid member is engaged. The closed state is maintained by the combination, and at the time of opening, it is impossible to open the lid member without destroying the engaging part, so that it is impossible to reseal. A contact lens storage container is disclosed.

  However, in any of the storage containers described in Patent Documents 2 to 4, the storage liquid can be stored in the container body even in an open state, as in the storage container described in Patent Document 1 described above. Therefore, the effect of preventing reuse has not been fully exhibited.

  Here, the present invention has been made in the background as described above, and the problem to be solved is to provide a contact lens storage container having a novel structure that can prevent reuse more effectively. There is.

  Hereinafter, embodiments of the present invention made to solve the above-described problems will be described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  That is, according to the first aspect of the present invention, in a contact lens storage container including a storage unit that stores a storage solution and stores the contact lens in an immersed state, the contact lens is inserted into the storage unit from the outside. A storage opening of a size that prevents the outflow of the contact lens stored in the storage portion is provided, and can be opened with a larger opening area than the storage port and is stored in the storage portion. Further, an outlet from which the contact lens can be taken out is formed so as to be openable and non-resealable at a position including a portion constituting at least one of the bottom wall and the peripheral wall of the housing portion when placed on a flat surface. It is characterized by being used disposable.

  In the contact lens storage container structured according to this aspect, the opening for taking out the contact lens can be opened at a position including a portion constituting at least one of the bottom wall and the peripheral wall of the housing portion and cannot be resealed. Therefore, after the contact lens is taken out, at least one of the bottom wall and the peripheral wall of the housing portion is in an open state that cannot be resealed. Therefore, even if an attempt is made to fill the storage liquid again, the bottom wall or the peripheral wall is opened, so that the storage liquid cannot be stored in the container after the opening operation. Thereby, in the storage container made into the structure according to this invention, after taking out a contact lens, it must be discarded, and reuse can be prevented more advantageously. As a result, the risk of bacterial infection resulting from repeated use of the storage container can be reduced more advantageously.

  In addition, a plurality of contact lens storage containers structured according to the present invention are provided to a general contact lens user as a set, for example. The lens is used in a new storage container. Here, the contact lens storage container having a structure according to the present invention is provided with a storage port into which a contact lens can be inserted from the outside, and therefore can easily accommodate the contact lens without requiring a special technique. This is possible, and even a general lens user can easily accommodate the lens.

  In addition, since it is difficult to take out the stored contact lens from such a storage port, the outlet must be opened when the contact lens is taken out. As a result, in the contact lens storage container having the structure according to the present invention, it is possible to advantageously prevent a usage method such as taking out the lens from the storage port without opening the outlet. It is possible to prevent the possibility of being used more advantageously.

  According to a second aspect of the present invention, in the contact lens storage container according to the first aspect, sealing means for sealing the storage port in a watertight manner is provided.

  In the contact lens storage container having the structure according to this aspect, since the storage port can be sealed, it is possible to advantageously prevent the storage liquid from flowing out of the storage port. Thereby, the storage container which is easy to carry can be realized. As is clear from this embodiment, the sealing means for the storage port is not necessarily required in the present invention. For example, as the first aspect, a storage container or the like in which the storage port is always opened can be adopted, and the storage solution is prevented from spilling in such a state that the storage port is opened vertically upward. It is also possible to use it in a stationary state.

  According to a third aspect of the present invention, in the contact lens storage container according to the first or second aspect, a cover member is overlaid on the container body on which the outlet is formed to seal the outlet. Thus, the housing portion is formed, and at least a part of the peripheral wall of the housing portion is constituted by the lid member.

  In the contact lens storage container structured according to this aspect, a part of the peripheral wall is configured by the lid member. Thereby, when removing a cover member from a container main body in order to express an outlet, a part of peripheral wall constituted with a cover member is destroyed simultaneously with removal. Thereby, after taking out the contact lens, a part of the peripheral wall of the outlet is destroyed, and it becomes impossible to store the preservative liquid only with the container body, thereby effectively preventing the possibility of reuse. I can do it. In addition, in this aspect, it is also possible to comprise substantially all of the peripheral wall with the lid member by covering the entire side surface of the container with the lid member. In this aspect, the storage port may be formed in either the container body or the lid member.

  According to a fourth aspect of the present invention, in the contact lens storage container according to the third aspect, the storage port is formed in the lid member.

  In the contact lens storage container having the structure according to this aspect, since the storage port is formed in the lid member that seals the outlet, the opening portion of the outlet can be used as the storage port. Thereby, the contact lens storage container according to the present invention can be realized with a simple configuration.

  According to a fifth aspect of the present invention, in the contact lens storage container according to the third or fourth aspect, the container body is opened to one of the vertically upper side and the lateral side in a mounted state on a plane. The outlet is formed, and a side end portion of the peripheral wall constituting one of the lateral sides of the container body is inclined inward of the container body.

  In the contact lens storage container having the structure according to this aspect, the side wall of the peripheral wall opened in the container main body is inclined so that the peripheral wall constituted by the lid member covering the opening is an inclined surface. Is done. Thereby, when removing a cover member from a container main body, it is made to be easy to spill a preservation | save liquid.

  According to a sixth aspect of the present invention, in the contact lens storage container according to any one of the first to fifth aspects, the opening can be opened at a position including a portion constituting the peripheral wall of the housing portion. And the bottom wall is inclined so as to descend toward the peripheral wall.

  In the contact lens storage container structured according to this aspect, the bottom wall is inclined, so that the storage solution stored in the housing portion can be quickly discharged when the contact lens is taken out. At the same time, storage of the storage solution can be made difficult, and reuse can be prevented more effectively.

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

  First, FIG. 1 schematically shows a lens case 10 as a contact lens storage container according to the first embodiment of the present invention. The lens case 10 is sealed by attaching a cover sheet 16 as a lid member to an outlet 30 to be described later of the container body 12, and a single contact lens 18 is stored in the container body 12. It is housed in a state immersed in the water. Here, the lens case 10 in the present embodiment is a storage container particularly used for storing and storing a soft contact lens, and the contact lens 18 is a soft contact lens that is easily deformable and is not a disposable type. A soft contact lens that is used for a plurality of days such as a disposable type that is not disposable for one day is used. In the following description, the vertical direction means the vertical direction in FIG. 1 unless otherwise specified.

  More specifically, the container body 12 includes a bottom plate 22 having a substantially rectangular plate shape, and peripheral walls 24a, 24b, 24c rising vertically from the outer peripheral edge portions of the three sides of the bottom plate 22, as schematically shown in FIG. Are formed in a substantially box shape, and in a state of being mounted on a flat surface, the upper surface opening 26 that opens upward and the side surface that opens to one of the side surfaces (the lower right direction in FIG. 2). An opening 28 is provided. The opening-side end surfaces 25 and 25 of the pair of peripheral walls 24b and 24c that are opposed to each other and form the side opening 28 are inclined surfaces that rise in an oblique direction toward the inside of the container body 12. . Furthermore, the opening side end surface 27 of the bottom plate 22 forming one side of the side opening 28 is an inclined surface having an inclination angle equal to the inclination angle of the peripheral walls 24b, 24c, and the side end surfaces 25, 25 of the peripheral walls 24b, 24c. And connected smoothly.

  Moreover, the dimension of the inner surface of the container 12 in the bottom plate 22 is made larger than the diameter dimension of the contact lens 18 to be accommodated. Accordingly, the contact lens 18 accommodated in the container 12 can be taken out through the upper surface opening 26 and the side surface opening 28. In the present embodiment, the contact lens 18 is removed by the upper surface opening 26 and the side surface opening 28. The take-out port 30 is configured.

  The container body 12 is appropriately made of industrial materials such as natural materials, metal materials, or synthetic resin materials, which are excellent in strength and chemical resistance in consideration of manufacturability, cost, handling properties, and the like. Examples of the metal material include an aluminum alloy, and examples of the natural material include a natural resin and fiber. For example, an appropriate synthetic resin can be used to ensure water impermeability, chemical resistance, and oxidation resistance. Used by impregnating or laminating materials. In addition, a ceramic material can be used as the non-metallic material. Examples of the synthetic resin that is particularly preferably employed include, for example, fluororesin, polyamide, polyarylate, polyethylene, polyethylene terephthalate, polyvinyl chloride, amorphous polyolefin, polycarbonate, polysulfone, polybutylene terephthalate, polypropylene, polymethylpentene, and the like. Or those composites or laminates are suitably employed. And the container main body 12 can be advantageously manufactured by integrally molding by injection molding using such a resin material, vacuum molding, pressure air molding, or the like.

  The container body 12 may be formed with a size that can accommodate the contact lens 18 in an undeformed state, or may be formed more compact by accommodating the contact lens 18 in a deformed state. good. Furthermore, the peripheral walls 24a to 24c are not necessarily raised vertically from the bottom plate 22, and may be raised inclined toward the inside of the bottom plate 22, for example. In the present embodiment, a contact lens 18 having a diameter of 14 mm is accommodated, and the width of the bottom plate 22 of the container body 12, in other words, the length of the bottom of the peripheral wall 24a: L1 is 15 mm. The length dimension of the bottom plate 22, in other words, the length dimension L2 of the bottom sides of the peripheral walls 24b and 24c: L2 is set within a range of 15 mm to 20 mm. The length dimension L3 of the upper side of the peripheral wall 24a is set within a range of 15 mm to 20 mm, and the length dimension L4 of the peripheral walls 24b and 24c is set within a range of 6 mm to 14 mm. Further, the height dimension L5 of the peripheral walls 24a to 24c is set within a range of 5 mm to 10 mm.

  And the cover sheet 16 as a cover member is stuck by the adhesion | attachment with respect to the upper surface opening part 26 and the side surface opening part 28 of the container main body 12. FIG. FIG. 3 schematically shows the upper surface of the cover sheet 16. The cover sheet 16 has a sheet shape having a rectangular shape in a top view, for example, a synthetic resin film such as polyethylene or polyester, a metal film such as aluminum foil, or a laminate made of a composite material of aluminum foil and synthetic resin. An impermeable material such as a sheet is preferably employed. Here, the cover sheet 16 has a rectangular shape that covers the entire outlet 30 of the container body 12, in other words, has a rectangular shape that covers the entire upper end surface of the container body 12.

  Further, the cover sheet 16 is provided with a storage port 32 as a storage port. The accommodation port 32 can be inserted with the contact lens 18 from the outside, but has a size and a shape that can prevent the contact lens 18 inserted into the container body 12 from flowing out. Preferably, the receiving port 32 prevents insertion of the non-deformed contact lens 18 and insertion of a finger, and can be inserted only in a state where the contact lens 18 is compressed and deformed with a finger or the like to reduce its diameter. It is formed with the size and shape to be. For example, in the present embodiment, the accommodation port 32 is a rectangular through hole whose maximum opening dimension is slightly smaller than the diameter dimension of the contact lens 18, and the longitudinal dimension L6 which is the maximum opening dimension is preferably Is 10 mm or less, more preferably 8 mm or less, and even more preferably 5 mm or less. As a result, the non-deformed contact lens 18 cannot be inserted into the receiving port 32, and is inserted into the receiving port 32 by compressing and deforming the contact lens 18 with a finger or the like and reducing its diameter. It is possible. Further, since the contact lens 18 accommodated in the container body 12 is released from the compressed state and has a diameter larger than the maximum opening dimension of the accommodation port 32, the contact lens 18 flows out through the accommodation port 32. Is blocked. At the same time, the cover sheet 16 is provided with a storage port cover 34 as a sealing means for sealing the storage port 32 in a watertight manner. The storage port cover 34 has a structure in which a member similar to the cover sheet 16 is formed in a film shape, and has a rectangular shape that is slightly larger than the storage port 32. Is fixed to the cover sheet 16 in an inseparable manner by adhesion or heat sealing. And the adhesive agent which adhere | attaches the accommodation port cover 34 so that resealableness is apply | coated to the circumference | surroundings of the accommodation port 32 with which the accommodation port cover 34 is overlaid. As such an adhesive, for example, a pressure-sensitive adhesive is preferably used, and specifically, polybutadiene, polyisoprene, natural rubber, nitrile rubber, epoxy-nylon, nitrile phenol, neoprene-phenol, and vinyl. -Phenolic pressure sensitive adhesives are exemplified. Thereby, the accommodation port 32 is resealable and watertightly sealed by the accommodation port cover 34.

  And the cover sheet | seat 16 made into such a structure is piled up on the upper surface of the container main body 12, and the outer peripheral edge part can peel with respect to the container main body 12 by adhesion | attachment, heat sealing, etc. over the perimeter. It is fixed to. As a result, the opening of the container body 12, specifically, the outlet 30 formed by the upper surface opening 26 and the side surface opening 28 is sealed with the cover sheet 16 in a watertight manner. Accordingly, a housing region 36 as a housing portion for housing the contact lens 18 is formed in the container body 12, and a peripheral wall that forms the housing region 36 is formed by the cover sheet 16 that covers the side opening 28. The part is composed. In particular, in the present embodiment, since the side opening 28 is inclined, the cover sheet 16 is bent at a bending line 38 that overlaps the connection position between the upper surface opening 26 and the side opening 28. It is fixed to the container body 12. In the state of being fixed to the container body 12, the accommodation port 32 is positioned on the upper surface opening 26.

  In particular, in the present embodiment, the cover sheet 16 constitutes a part of the peripheral wall in any (usually conceivable) mounting state on the plane of the container body 12. That is, for example, when the container body 12 is placed on a flat surface with the peripheral wall 24a as a bottom plate, the upper opening 26 is opened to the side, and the cover sheet 16 that covers the upper opening 26 is provided on the bottom plate 22. The peripheral walls are formed together with the peripheral walls 24b and 24c. If the container body 12 is erected with the peripheral wall 24a as a bottom plate, the cover sheet 16 that covers the upper opening 26 is left, and only the side opening 28 is opened, so that the cover sheet that covers the upper opening 26 is covered. 16, the bottom plate 22, and the peripheral walls 24 b and 24 c, the storage solution 20 may be stored in the region surrounded by the lens case 10, but in the present embodiment, the upper opening 26 is used. Since the length dimension L4 is smaller than that of the contact lens 18, the contact lens only in the region surrounded by the cover sheet 16, the bottom plate 22, and the peripheral walls 24b and 24c covering the upper opening 26 is provided. It is impossible to immerse the whole 18 in the storage solution 20, and it is substantially impossible to reuse it as a storage container. However, the height dimension L5 of the peripheral wall 24a is made smaller than the length dimension L2 of the bottom plate 22, or the peripheral wall 24a is formed as an inclined surface or a curved surface, whereby the peripheral wall 24a is used as the bottom plate. For example, the container body 12 may be prevented from being placed on a flat surface.

  When the contact lens 18 is accommodated in the lens case 10 having such a structure, first, the accommodation port cover 34 that seals the accommodation port 32 is opened so that the accommodation port 32 is exposed to the outside of the lens case 10. . Then, the storage solution 20 is stored in the storage region 36 by injecting the storage solution 20 into the storage region 36 from the storage port 32.

  Subsequently, as shown in FIG. 4, the contact lens 18 is housed in the housing region 36 through the housing port 32. Here, in particular, since the longitudinal dimension of the accommodation port 32 in the present embodiment is smaller than the diameter size of the contact lens 18, when the contact lens 18 is inserted into the accommodation port 32, the contact lens 18 is removed. It is inserted in a state where it is compressed and deformed into a suitable shape with fingers and made small. Then, by sealing the housing port 32 again with the housing port cover 34, as shown in FIG. 5, the contact lens 18 is housed in the housing region 36 while being immersed in the storage solution 20. . Note that the contact lens 18 that has been compressed and deformed and inserted into the receiving port 32 is released from the compressive force of the fingers, so that the size of the contact lens 18 is balanced in the receiving region 36, in other words, the maximum of the receiving port 32. The diameter dimension is larger than the opening dimension (in the present embodiment, the longitudinal dimension of the accommodation port 32). Thereby, the contact lens 18 accommodated in the accommodation region 36 is prevented from flowing out from the accommodation port 32. Further, since the storage port 32 is sized to prevent insertion of fingers, it is impossible to insert the fingers from the storage port 32 and take out the contact lens 18.

  On the other hand, when the contact lens 18 is taken out from the lens case 10 in which the contact lens 18 is accommodated, the entire cover sheet 16 fixed to the container body 12 is peeled off as shown in FIG. Thereby, the sealing state by the cover sheet 16 of the upper surface opening part 26 and the side surface opening part 28 of the container main body 12 is released, and the outlet 30 is exposed to the outside, and the contact lens 18 is exposed from the outlet 30. Can be taken out.

  Here, particularly in the present embodiment, when the cover sheet 16 is peeled off in order to take out the contact lens 18, the sealed state of the side opening 28 is released. As a result, the container body 12 is opened to the side surface through the side opening 28, and the preserving solution 20 stored in the container body 12 is leaked out of the container body 12 from the side opening 28. That is, the lens case 10 according to the present embodiment has the side opening 28 formed in the container main body 12, so that the liquid storage solution 20 cannot be stored only by the container main body 12, and the side surface is covered by the cover sheet 16. By covering the opening 28, the peripheral wall 24 a to 24 c of the container body 12 and the cover sheet 16 that covers the side opening 28 are included, and a peripheral wall for storing the storage solution 20 in the storage region 36 is configured. It is.

  Further, particularly in the present embodiment, the opening size of the upper surface opening 26 is smaller than the opening size of the side surface opening 28, and for example, the cover sheet 16 is partially peeled off to form the upper surface opening 26. It is difficult to take out the contact lens 18 only by opening it. Therefore, in order to secure the opening size of the outlet 30 to such an extent that the contact lens 18 can be taken out, substantially the entire cover sheet 16 reaching the side opening 28 must be peeled off.

  Since the cover sheet 16 is fixed to the container body 12 with an adhesive or heat seal, the outlet 30 is sealed again using the cover sheet 16 completely peeled off from the container body 12. The lens case 10 is discarded after the cover sheet 16 is peeled off and the contact lens 18 is taken out.

  The lens case 10 having such a structure is provided to a general contact lens user by setting a plurality of disposable storage containers in a state where the container body 12 is sealed with, for example, a cover sheet 16. According to the lens case 10 of the present embodiment, when the contact lens 18 is accommodated, as described above, it can be easily accommodated by opening the accommodation port cover 34. Even a general contact lens user who does not have a lens can easily perform the housing operation. Since the fingers are prevented from entering the storage port 32, the fingers are prevented from directly touching the storage solution 20 stored in the lens case 10, and bacteria attached to the fingers are stored in the storage solution. The risk of entering 20 is also reduced.

  When the cover sheet 16 is peeled to take out the contact lens 18, it is impossible to re-adhere the cover sheet 16 to the container body 12. Can be prevented. Thereby, the lens user can always be provided with a new lens case 10, and the hygienic condition can be kept good.

  Further, particularly in the present embodiment, when the cover sheet 16 is peeled off, the container body 12 is opened to the side surface through the side opening 28, so that the storage solution 20 leaks from the side opening 28 and the container body It is impossible to store the preservation solution 20 only by the number 12. As described above, in the lens case 10 according to the present embodiment, after the contact lens 18 is taken out, not only the cover sheet 16 is resealed but also the storage solution 20 cannot be stored. Therefore, the lens user is forced to discard the lens case 10, and it is possible to more advantageously avoid the lens case 10 being used again after being opened. In addition, in the lens case 10 of the present embodiment, since the accommodation port 32 is made smaller than the diameter of the lens, once the contact lens 18 is accommodated in the accommodation region 36, it can be taken out from the accommodation port 32. In order to take out the contact lens 18, the cover sheet 16 must be peeled off, and the possibility of reuse can be more advantageously avoided.

  As mentioned above, although one embodiment of the present invention has been described in detail, this is merely an example, and the present invention is not construed as being limited in any way by the specific description in the embodiment. Structures and the like as in the embodiments exemplified below can also be suitably employed. In addition, in the following description, about the member and site | part made into the structure similar to the above-mentioned 1st embodiment, respectively, by attaching | subjecting the code | symbol same as 1st embodiment in a figure, those Detailed description is omitted.

  For example, the specific structure of the storage port for storing the contact lens in the storage region and the sealing means for sealing the storage port in a watertight manner is not limited. As a different aspect of the storage port, in the lens case 10 as the first embodiment described above, for example, the lens case 40 as the second embodiment of the present invention shown in FIG. A cylindrical opening cylinder portion 42 is provided at a position overlapping the upper opening portion 26, and the accommodation region 36 and the external space are communicated with each other through the opening cylinder portion 42, and a screw is formed on the outer peripheral surface of the opening cylinder portion 42. And the sealing means which seals the opening part 46 of the opening cylinder part 42 watertight is comprised by screwing the bottomed cylindrical cap 44 in which the screw | thread was formed in the inner peripheral surface to the opening cylinder part 42. May be equal. In such an embodiment, the opening 46 of the opening cylinder 42 is a storage port, and the opening shape is a substantially circular shape having a diameter smaller than the diameter of the contact lens 18. The contact lens 18 is rounded to the extent that it enters the opening 46 and inserted into the opening cylinder 42.

  FIG. 8 shows a lens case 50 as a third embodiment of the present invention as a further different aspect of the storage port and the sealing means. The lens case 50 is integrally formed with an opening 52 projecting upward in a substantially cylindrical shape at a position corresponding to the upper surface opening 26 of the container body 12 in the cover sheet 16. The opening 52 is formed with an opening size that allows the contact lens 18 to be reduced or deformed or inserted in an undeformed state, and a convex male strip 54 and a concave shape are formed on the inner peripheral surface of the opening edge. A zipper 58 is provided as a sealing means constituted by the female strip 56 being opposed to each other. As a result, the opening 52 allows the contact lens 18 to be inserted in the opening state shown in FIG. 8A, and allows the male strip 54 and the female strip 56 to bite as shown in FIG. 8B. Can be sealed in a watertight manner.

  However, a sealing means for sealing the storage port is not always necessary. For example, without providing a sealing means, even if the storage port is always open, the storage solution can be used in a stationary state in which the storage solution does not leak out.

  Further, the shape of the container body is not limited to the shape as described above. For example, FIG. 9 shows a lens case 60 as a fourth embodiment of the present invention. A container main body 62 in the lens case 60 is a substantially conical container that is gradually reduced in diameter in the axial direction, and an opening 64 having a position corresponding to the bottom surface of the cone. Then, similarly to the lens case 10 as the first embodiment described above, the seat cover 16 is fixed to the opening 64 so that the accommodation region 36 is formed inside the container body 62. Yes. In such a lens case 60, the contact lens 18 is accommodated in the accommodating region 36 through the accommodating port 32 formed in the seat cover 16. Then, by peeling the seat cover 16, the opening 64 is made to communicate with the outside, and the contact lens 18 can be taken out.

  Here, in the lens case 60 in the present embodiment, since the container main body 62 has a tapered shape, as shown in FIG. 9B, the container main body 62 falls down when placed on a flat surface. Thus, the opening 64 is opened to the side. Therefore, the storage liquid 20 stored in the storage area 36 is discharged from the container main body 62 through the opening 64, and the container main body 62 stores the storage liquid 20 in the container main body 62 without the cover sheet 16. It is impossible to leave. In the cover sheet 16, a storage port 32 as a storage port is formed at a position overlapping with the opening 64 in substantially the same manner as the lens case 10 as the first embodiment described above. The housing cover 34 is sealed in a watertight manner. Therefore, the contact lens 18 inserted from the accommodation port 32 is accommodated in the container main body 62 through the opening 64. In this embodiment, the contact lens 18 is inserted into the contact lens 18 and the contact lens. The outlet for taking out 18 is configured using the same opening 64.

  In addition, the lens case 60 in the present embodiment can be placed on a plane with the opening 64 opened downward. In such a case, the bottom wall of the accommodation area 36 is constituted by the cover sheet 16, and the bottom wall can be opened.

  FIG. 10 shows a lens case 70 as a fifth embodiment of the present invention. The lens case 70 is a storage container that is preferably used for housing a hard contact lens, and has a cylindrical container body 72 that is hollow. The internal space and the outside are communicated with each other by an opening 74 penetrating the side surface of the container body 72 over a predetermined circumferential dimension, and the opening 74 is sealed by the seat cover 16. An accommodation region 36 is formed. Further, a storage port 76 is provided through the upper surface of the container body 72. Here, the accommodating port 76 has a substantially similar shape that is slightly larger than the projected shape perpendicular to the lens optical axis of the contact lens 18, and the contact lens 18 is compressed in a direction equal to the extending direction of the lens diameter. It is inserted into the receiving port 76 in a non-deformed state without being deformed, and is received in the receiving area 36. As is clear from this embodiment, the storage port in the present invention does not necessarily have to be formed in the lid member, and may be formed in the container body, and the storage port and the outlet are in different locations. It may be formed independently. Since the accommodation port 76 has a specific shape as described above, for example, even if the lens case 70 is turned upside down and the contact lens 18 is taken out from the accommodation port 76, the contact can pass through the accommodation port 76. The direction of the lens 18 is limited, and the contact lens 18 is substantially prevented from flowing out of the accommodation port 76. As described above, the storage port according to the present invention may not only adjust the opening size but also prevent the contact lens from flowing out by appropriately setting the shape.

  Moreover, since the container main body 72 has the opening part 74 in the side surface, it cannot keep the preservation | save liquid in the state which orient | assigned the axis | shaft to the perpendicular direction. Furthermore, for example, as shown in FIG. 10B, even when the axis is oriented in the horizontal direction, the container main body 72 has a cylindrical shape and cannot be stably placed in a flat shape, and the opening 74 is not formed. Since it is opened on the side surface, it is also difficult to store the preservation solution. Further, when the shaft is oriented in the horizontal direction, the storage port 76 is also opened on the side surface, so that the preservative solution can be discharged from the storage port 76, which makes reuse more difficult. Yes. Here, the side surface refers to a surface formed by a peripheral wall of a portion that rises from the lowermost portion (the deepest portion) among the portions constituting the wall portion of the housing region 36 when the container main body 72 is placed on a flat surface. .

  FIG. 11 shows a lens case 80 as a sixth embodiment of the present invention. The lens case 80 has substantially the same structure as the lens case 10 according to the first embodiment described above, and the bottom plate 82 of the container body 12 constituting the bottom wall of the housing portion extends from the peripheral wall 24a to the side opening 28. It is formed so as to incline downward toward. In FIG. 11, for ease of understanding, the contact lens accommodated in the accommodation region 36 is omitted. In this way, when the cover sheet 16 is peeled off and the side opening 28 is opened, the storage liquid 20 is allowed to flow toward the side opening 28, so that the storage liquid 20 can be discharged more quickly. I can do it. At the same time, by making the lower wall of the housing portion an inclined surface, it is possible to make the storage of the preservation solution 20 more difficult and prevent reuse more advantageously.

  FIG. 12 shows a lens case 90 as a seventh embodiment of the present invention. In the lens case 90, container bodies 12a and 12b, which are substantially the same as the lens case 10 in the first embodiment described above, are provided on a connecting plate 92 having a rectangular plate shape for the right eye and the left eye. The cover sheet 16 is fixed to each of the pair of container main bodies 12a and 12b. If such a lens case 80 is used, the left and right lenses can be accommodated, and therefore the possibility of losing the lens can be reduced.

  Although not shown, for example, in the lens case 10 according to the first embodiment described above, in order to ensure an adhesion area with the cover sheet 16, the lens case 10 spreads outward to the upper surface opening 26 and the side surface opening 28. A flange-like portion may be formed.

  Further, the lid member is not necessarily limited to a sheet-like easily deformable member. For example, in the first embodiment described above, the outlet 30 may be sealed in a watertight manner using a hard lid member that covers the outlet 30 of the container body 12. Even in this case, when the lid member is removed from the container main body 12, the container main body 12 is opened to the side surface in the same manner as in the first embodiment. Can be difficult to save.

  In addition, the size of the accommodation area does not necessarily have to be larger than that of the contact lens to be accommodated. For example, when the contact lens to be accommodated is a soft contact lens that can be easily deformed, the contact lens is in a deformed state. The volume may be small enough to be accommodated.

  In addition, the storage container in the present invention can be shipped in a state where a storage solution or the like is stored in the storage area in advance. For example, it can be used as an emergency storage container when the storage container is lost at a travel destination by selling the storage liquid in a stored state.
