Description

  The present invention relates to a disposable processing case in which a contact lens is accommodated and subjected to any treatment such as storage, disinfection, sterilization, etc., particularly when such treatment is performed. The present invention relates to a disposable processing case for a contact lens that is also provided with a processing solution to be used.

  In general, contact lenses include a disposable type (disposal type) that is used for a relatively short period of time such as one week or two weeks, and a normal type that is used for a relatively long period of time such as one year or two years. However, any contact lens except a one-time-use disposable type will be used for a predetermined period. When contact lenses are used over a plurality of days, most of the contact lenses are worn every day when waking up and removed at bedtime.

  By the way, since contact lenses are worn on the corneal surface of the human body, it is necessary to prevent scratches and bacterial contamination even in a removed storage state. In addition, hydrous contact lenses swell so that they can be worn quickly. It is necessary to keep in a state. Therefore, after removing the contact lens, a special storage processing case is filled with a specific storage processing solution, and the contact lens is immersed therein for storage processing.

  Furthermore, since the contact lens is used in contact with both the body fluid of the human body and the outside air, contaminants such as proteins, lipids, and bacteria are likely to adhere during use. Therefore, in many contact lenses, a specific chemical treatment case is filled with a specific treatment solution for protein removal or sterilization at an appropriate frequency, such as every day or every few days, and the contact lens is immersed therein. Treatments such as kimono removal and sterilization are performed.

  Therefore, as described above, as a storage processing case for storing contact lenses and a chemical processing case for removing or disinfecting deposits, a processing case made of a hard resin having an openable / closable lid is provided. Accordingly, an appropriate processing solution such as a preserving solution, a protein removing solution, or a disinfecting solution is injected and used. At that time, the processing case is repeatedly used by exchanging only the processing liquid to be injected.

However, such conventional processing cases have the following problems (a) to (e).
(A) Continuing to use repeatedly, contamination of the processing case by bacteria or the like tends to be a problem.
(B) When going out on a trip or business trip, it was troublesome to carry a bottle of processing liquid separately from the processing case.
(C) Depending on the type of contact lens, multiple types of processing liquids such as preservatives, disinfectants, and neutralizing liquids may be required. Therefore, it is necessary to prepare multiple bottles containing them separately from the processing case. In particular, it was troublesome to handle during travel and business trips.
(D) Even when using disposable contact lenses that are discarded in a short period of one to two weeks, carry a bottle of processing solution in addition to the processing case for processing such as sterilization and disinfection every few days. Therefore, having to go on a trip, a business trip, etc. greatly hinders the advantages such as convenience and simplicity of using a disposable sip contact lens.
(E) Depending on the type of contact lens and processing solution, etc., multiple different processing solutions may be used in combination. However, an appropriate amount must be poured from each case into the processing case and mixed. Therefore, it is troublesome and difficult to set the mixing ratio accurately.

  In order to cope with the above problem (a), Patent Document 1 (Japanese Patent Publication No. 8-509192) and Patent Document 2 (Japanese Patent Application Laid-Open No. 2002-306227) disclose a disposable contact lens. A processing case has been proposed. However, the processing case described in Patent Document 1 is made disposable once or several times by simply simplifying the processing case provided conventionally using a simple resealing structure such as an interlock mechanism. However, it is basically the same as the processing case of the conventional structure, and does not provide any solution for the above problem. In addition, the processing case described in Patent Document 2 is only forcibly prevented from being repeatedly used by giving the processing case irreversible damage that makes it impossible to reuse after being opened once. Certainly it may be effective in dealing with the problem of contamination of the processing case due to repeated use, but it does not present any solution to the above mentioned other problems and is particularly irreversible In order to realize a structure for giving damage, there is a new problem that the structure and handling of the case is complicated and the manufacturing cost is increased.

The material of the container body 14 is not limited in any way, but it is desirable to adopt a synthetic resin material having excellent strength and chemical resistance in consideration of manufacturability, cost, handling, etc. Fluorine resin, polyamide, polyacrylic acid, polyethylene, polyethylene terephthalate, polyvinyl chloride, amorphous polyolefin, polycarbonate, polysulfone, polybutylene terephthalate, polypropylene, polymethylpentene, etc., or composites or multilayer structures thereof. Preferably employed. An internal space of the container body 14 is defined as a lens housing region 12 that is defined by a wall portion including a peripheral wall portion 18 and a bottom wall portion 20 and opens upward.

  The lens housing area 12 is appropriately sized to accommodate the contact lens 22 (see FIG. 5). The material and type of the contact lens 22 to be applied are not limited at all. For example, this embodiment is applied to a disposable hydrophilic soft contact lens made of HEMA (hydroxyethyl methacrylate). The processing case 10 can be advantageously applied.

  Furthermore, a cover sheet 16 is placed on the opening of the container body 14, and the cover body 16 is sealed so that the opening of the container body 14 can be opened. Here, the sealing structure by the cover sheet 16 is not particularly limited, and a sealing structure that can be repeatedly opened and closed by, for example, a conventionally known zip lock or interlock can be arbitrarily adopted.

  Specifically, for example, as shown in FIG. 3, locking protrusions 24 that protrude on the inner peripheral surface are formed on substantially the entire circumference in the circumferential direction at the peripheral edge of the opening of the peripheral wall 18 in the container body 14. While projecting so as to extend over, a pair of inner and outer annular projecting portions 23, 25 extending in the circumferential direction on the outer peripheral portion are projected from the inner surface of the cover sheet 16. And the sealing structure of the container main body 14 by the cover sheet | seat 16 is carried out by inserting the latching protrusion 24 of the container main body 14 with the annular protrusions 23 and 25 inside and outside by elastically deforming the cover sheet | seat 16, etc. Can be realized.

  The cover sheet 16 is corrosion-resistant with respect to a treatment liquid 38 to be described later, and is non-permeable material so as to prevent the contents such as the treatment liquid 38 and the contact lens 22 from leaking out of the container. Is used to form a film of a single layer or a multilayer structure.

The diaphragm 36 is impermeable and prevents the treatment liquid from passing through the communication port 34. Further, the diaphragm 36 is formed into a thin film shape, and an appropriate material is selected, scratches or the like are applied in advance so that the diaphragm 36 can be easily broken when pressure is applied to the film surface. A stress concentration site is formed, and a planned fracture portion is formed. As the material of the diaphragm 36, for example, a synthetic resin material, a metal thin film, or the like listed as the material of the container body 14 can be appropriately employed in consideration of the corrosion resistance against the processing liquid 38 to be described later.

  In addition, predetermined processing liquids 38a and 38b are respectively stored in the processing liquid storage areas 32a and 32b that are sealed with respect to the external space and blocked from the lens storage area 12 in this way. These treatment liquids 38a and 38b are not limited in any way, and various kinds of treatment liquids may be employed depending on the treatment to be performed on the contact lens 22. Specific examples include MPS (Multi Purpose Solution), protein washing solution, protein washing aid, hydrogen peroxide solution, EDTA (ethylenediaminetetraacetic acid), polyvinylpyrrolidone (so-called povidone), povidone iodine, washing preservation solution, eye washing solution, In addition to a rinsing solution, a proteolytic enzyme solution, a preservation solution, and the like, various solutions that sterilize, disinfect, and wash the contact lens 22, the lens housing region 12, the eye, and the like are employed.

  Incidentally, the above-described MPS is used as a treatment liquid that can collectively exhibit the cleaning effect, the rinsing effect, the storage effect, and the like for the contact lens 22 and the lens housing region 12. The protein washing liquid is configured to contain sodium hypochlorite, and is used as a treatment liquid for washing and removing proteins adhering to the contact lens 22 and the like. The protein washing aid comprises potassium bromide and replaces hypochlorite with hypobromite. By adding this protein cleaning aid to a protein cleaning solution or the like, the protein cleaning effect is improved as compared to using hypochlorite alone, and the safety is improved. Further, the hydrogen peroxide solution is used as a treatment liquid that can exert a bactericidal effect and a storage effect on the contact lens 22 and the like. When hydrogen peroxide solution is used as the treatment liquid 38, the hydrogen peroxide solution is neutralized using a catalyst such as Pt or an appropriate rinsing solution is used to ensure the safety of the wearer. After rinsing the hydrogen peroxide solution adhering to the lens, the contact lens 22 is worn, and a rinsing liquid necessary for this is adopted as the treatment liquid. Moreover, EDTA is employ | adopted as a process liquid for performing a neutralization process by adding to hydrogen peroxide solution, povidone iodine, etc. Furthermore, since EDTA has the ability to prevent calcium from adhering to the contact lens 22 and the like by chelating calcium and the like contained in tears, Adopted as a treatment liquid for the stability of the component. Polyvinylpyrrolidone is used as a treatment liquid as a so-called thickener or thickener that improves the viscosity of the liquid. Povidone iodine is a liquid in which iodine is included in polyvinyl pyrrolidone, and is used as a treatment liquid such as a bactericide. The cleaning storage solution is employed as a processing solution capable of exhibiting the lens cleaning effect and storage effect. The eyewash is used as a treatment liquid for use in eye washing after the contact lens 22 is removed or when a contact lens wearer complains of eye discomfort. The rinsing liquid is a process for rinsing dust, bacteria, or the like attached to the contact lens 22, or rinsing the sterilizing agent attached to the contact lens 22 after sterilizing with a sterilizing agent such as hydrogen peroxide. Adopted as a liquid. The proteolytic enzyme solution is used, for example, as a treatment solution that cleans the contact lens 22 by decomposing the protein or denatured protein adsorbed or fixed on the lens surface by dropping it into a storage solution in which the contact lens 22 is immersed. Is done. The preservation solution includes, for example, a sterile aqueous solution, isotonic saline, and the like, and is employed as a treatment solution that prevents the contact lens 22 from being dried and maintains the contact lens 22 in a ready-to-use state.

  As described above, the contact lens 22 requires various processing liquids according to the type and purpose thereof, but the two processing liquid storage areas 32 and 32 in the present embodiment include those processing liquids. Thus, a suitably selected one is accommodated. In this case, the processing liquid stored in the processing liquid storage regions 32 and 32 is not specifically limited, and the above-described various liquids, liquids obtained by appropriately mixing them, or the like can be appropriately employed. It should be understood.

  Further, the combination of the treatment liquids 38 stored in the two treatment liquid storage areas 32 is not particularly limited. Specifically, for example, MPS may be stored in one treatment liquid storage area 32a and a proteolytic enzyme solution may be stored in the other treatment liquid storage area 32b. Further, the protein cleaning liquid may be stored in one of the processing liquid storage areas 32a, and the protein cleaning auxiliary agent may be stored in the other processing liquid storage area 32b. Further, the hydrogen peroxide solution may be stored in one of the processing liquid storage areas 32a, and EDTA may be stored in the other processing liquid storage area 32b. Furthermore, low-temperature hydrogen peroxide solution may be stored in one treatment liquid storage region 32a, and EDTA / NaFe (or Fe ion aqueous solution) may be stored in the other treatment solution storage region 32b. Further, povidone may be accommodated in one treatment liquid storage area 32a, and a reducing agent such as EDTA may be accommodated in the other treatment liquid storage area 32b. Further, the cleaning storage liquid may be stored in one processing liquid storage area 32a, and the rinsing liquid may be stored in the other processing liquid storage area 32b. In the case of using these washing preservation solution and rinsing solution, the contact lens 22 and the like can be rinsed even in a place where there is no tap water. Furthermore, the eyewash solution may be stored in one treatment liquid storage region 32a and the MPS may be stored in the other treatment solution storage region 32b. In the case of using these eyewash and MPS, the container body 14 is used as an eyewash cup by introducing the eyewash from the treatment liquid storage area 32a into the lens housing area 12 and washing the eye. While discarding the liquid, MPS can be introduced from the treatment liquid storage area 32b into the lens housing area 12, and the lens can be immersed in the MPS for sterilization. Of course, it is possible to store the same kind of liquid in both the treatment liquid storage regions 32a and 32b.

  Incidentally, in the present embodiment, the processing liquid 38a containing hydrogen peroxide is stored in one processing liquid storage area 32a, and the processing liquid 38b containing EDTA is stored in the other processing liquid storage area 32b. .

  In the disposable processing case 10 having such a structure, for example, a pressing operation with a finger as an external operation is performed on any storage film 30a, 30b to pressurize the processing liquid storage regions 32a, 32b, and the processing liquid 38a, The diaphragm 36 can be broken by applying an external force to the diaphragm 36 through the pressure 38b. As a result, the pressurized treatment liquid storage regions 32 a and 32 b are introduced into the lens housing region 12 through the communication port 34 and 34 through the broken portion of the diaphragm 36.

  After the storage films 30a and 30b are pressed and deformed and the processing liquids 38a and 38b are discharged toward the lens storage area 12, the backflow of the processing liquids 38a and 38b from the lens storage area 12 to the processing liquid storage area 32 is performed. Is to be prevented. Specifically, for example, the fractured diaphragm 36 is formed with a shape or structure in which the function of the check valve is exhibited, or the weight of the processing liquids 38a and 38b accommodated in the container main body 14 and the lens accommodating region 12 The storage film 30a, 30b is configured to be held in a crushed state, or the material of the storage film 30a, 30b is selected so as not to be restored after the storage film 30a, 30b is crushed. Thus, the backflow prevention of the processing liquids 38a and 38b from the lens storage area 12 to the processing liquid storage area 32 can be realized.

  Next, although the specific example which performs a specific process to the contact lens 22 using the disposable processing case 10 of this embodiment is demonstrated, the usage condition of this processing case 10 is not limited to this specific example.

  First, a disposable processing case 10 as shown in FIGS. 1-2 is prepared. As is clear from the above description, in the processing case 10 of the present embodiment, in addition to the lens housing region 12 being empty before use, the cover sheet 16 is a peripheral wall portion of the container body 14. Since the lens housing area 12 is completely sealed, the lens housing area 12 is completely sealed.

  When using such a processing case 10, first, as shown in FIG. 4, by grasping the grip portion 27 of the cover sheet 16 and peeling only a small part of the cover sheet 16 from the container body 14, It is assumed that the exhaust from the lens housing region 12 is allowed. Thereafter, a pressing operation such as a finger is performed on the storage film 30a constituting a part of the wall portion of the processing liquid storage region 32a containing the processing liquid 38a containing the hydrogen peroxide solution. As a result, the pressure in the processing liquid storage area 32 a is increased to break the diaphragm 36, and the processing liquid 38 a is introduced into the lens housing area 12 through the communication port 34.

  Thereafter, the cover sheet 16 is largely peeled from the container main body 14, and the lens housing region 12 is sufficiently opened in a state where the fixing portion is left only in the connection holding region 26. Under such a state, the contact lens 22 that has been worn is removed, and the lens is loaded into the lens housing region 12 through the opening, and immersed in a hydrogen peroxide solution 38a as a treatment liquid. Subsequently, as shown in FIG. 5, the cover sheet 16 once opened is again superimposed on the opening of the container body 14, and the locking protrusions 24 of the container body 14 are inserted into the locking grooves 28 of the cover sheet 16. To fit the lens housing region 12 into a sealed state.

  In this state, the contact lens 22 is sterilized with a treatment liquid 38a made of hydrogen peroxide solution by leaving it to stand for a predetermined time. Thereafter, a pressure operation such as a finger is applied to the storage film 30b constituting a part of the wall of the processing liquid storage region 32b containing the processing liquid 38b containing EDTA to break the diaphragm 36, and the processing liquid 38b is communicated. The lens is introduced into the lens housing region 12 through the mouth 34. Accordingly, as shown in FIG. 6, the hydrogen peroxide solution is neutralized by mixing the treatment solution 38b made of hydrogen peroxide contained in the lens containing region 12 with the treatment solution 38b containing EDTA. Thus, measures are taken to avoid an excessive adverse effect on the contact lens 22. Then, the contact lens 22 that has been sterilized can be obtained by removing the contact lens 22 from the lens housing region 12 thereafter.

  On the other hand, the processing case 10 is used when the two diaphragms 36 and 36 are broken, and cannot be reused in terms of appearance and function. Therefore, the processing case 10 is discarded together with the processing liquids 38a and 38b.

  In the disposable processing case 10 having the above-described structure, not only the lens storage area 12 but also the processing liquid storage areas 32a and 32b that previously store the processing liquids 38a and 38b are integrally provided. It is not necessary to carry a large bottle filled with an appropriate processing solution separately from the processing case, and in particular, only the processing case 10 is carried in the disinfection process as described above in which two liquids are required. Since it is possible to go on a business trip or a trip, the convenience of the contact lens can be greatly improved.

  In addition, in the processing case 10 of the present embodiment, the processing liquid 38 stored in the processing liquid storage region 32 is passed through the communication port 34 provided in the partition portion between the processing liquid storage region 32 and the lens storage region 12. 12 is directly injected into the processing case 10 and it is not necessary to take out the processing liquid 38 to the outside, so that the processing liquid 38 can be easily and reliably introduced into the lens housing region 12. As a result, spilling out of the container can be prevented.

  Further, in the processing case 10 of the present embodiment, the cover sheet 16 is fixedly held on the case main body 14 even after the cover sheet 16 is opened (the connection holding region 26). The cover sheet 16 can be easily stopped, and the cover sheet 16 can be prevented from being lost. Also, since the processing case 10 can be handled integrally when it is discarded after use, the handling is easy. Become.

  Furthermore, in the processing case 10 of the present embodiment, the lens storage area 12 is an empty space that does not contain the processing liquid 38 in the initial state provided to the user. It is also possible to inject a separately prepared storage solution and use it as a storage case for contact lenses, and after using it as a storage case, disinfection treatment can also be performed.

  Further, in the processing case 10 of this embodiment, the processing liquids 38a and 38b are stored in the processing liquid storage areas 32a and 32b as much as necessary for one processing. In addition, the processing liquids 38a and 38b can be efficiently used in a necessary amount without waste, and even when the two liquids are mixed as described above, the mixing ratio of the two liquids can be accurately determined. It is possible to easily set and execute processing.

  In the processing case 10 of the present embodiment, the two processing storage areas 32a and 32b are formed independently of each other, and are connected to the lens housing area 12 by communication ports 34 and 34 formed separately. Therefore, as described above, an appropriate type of processing liquid can be stored in each of the processing liquid storage areas 32 and 32 according to the target processing of the contact lens 22. Needless to say, it is possible to deal with a wide variety of processes according to the user's request.

  Next, FIG. 7 shows a disposable processing case 40 as a second embodiment of the present invention. In the following description of each embodiment including the present embodiment, the same reference numerals as those in the first embodiment are used for members and parts having the same structure as in the first embodiment. By attaching, detailed description thereof will be omitted.

  In the disposable processing case 40 according to the present embodiment, three storage films 30a, 30b, and 30c are provided on the bottom wall portion (20) of the container body. Each of these storage films 30a, 30b, and 30c has a substantially circular cup shape that opens upward, and is fixed fluid-tightly to the bottom wall portion of the container body 14 at the periphery of the opening. Thereby, in this embodiment, the process storage area | region (32) defined by the storage film 30 and the bottom wall part (20) is provided three mutually independently, These process liquid storage area | regions (32) ), The processing liquid (38) is accommodated, and is provided independently of the lens accommodation area (12) via the communication port 34 provided with the diaphragm (36).

  The kind and combination of the processing liquid (38) accommodated in each of these processing liquid storage areas (32) are not limited at all as in the first embodiment. Specifically, for example, MPS is accommodated in one treatment liquid storage area (32a), a proteolytic enzyme solution is accommodated in another treatment liquid storage area (32b), and another treatment liquid storage area (32c). The rinse liquid may be accommodated. Further, a cleaning liquid such as a protein cleaning liquid is stored in one processing liquid storage area (32a), a sterilization liquid such as hydrogen peroxide is stored in another processing liquid storage area (32b), and another processing liquid storage area. You may make it accommodate a rinse in (32c). Alternatively, the protein cleaning liquid is stored in one processing liquid storage area (32a), the protein cleaning auxiliary agent is stored in another processing liquid storage area (32b), and the rinsing liquid is stored in another processing liquid storage area (32c). You may make it accommodate. Alternatively, the hydrogen peroxide solution is stored in one processing liquid storage area (32a), the EDTA is stored in another processing liquid storage area (32b), and the rinsing liquid is stored in another processing liquid storage area (32c). You may make it accommodate. Further, povidone is accommodated in one treatment liquid storage area (32a), a reducing agent is accommodated in another treatment liquid storage area (32b), and a rinse liquid is accommodated in another treatment liquid storage area (32c). Anyway. It is of course possible to store the same type of liquid, for example, a storage liquid, in each processing liquid storage area 32.

  Therefore, in the disposable processing 40 case structured according to the present embodiment, three treatment liquid storage regions (32) are provided independently of each other. It becomes possible to cope with processing.

  Next, FIGS. 8 to 9 show a disposable processing case 50 as a third embodiment of the present invention. In the processing case 50, a pair of storage films 30 a and 30 b are fixedly provided on the outer peripheral surface of the peripheral wall portion 18 of the container body 14. That is, a pair of storage films 30a and 30b having a bottomed substantially bag shape or cup shape are fluid-tightly fixed to the peripheral wall portion 18 of the container body 14 at the peripheral edge portion of the opening, thereby storing the storage film 30. And the peripheral wall part 18 of the container main body 14 constitutes a wall part to form treatment liquid storage areas 32a and 32b. In addition, a communication port 34 covered with a diaphragm 36 is provided through each of the peripheral wall portions 18 constituting a part of each wall portion of each treatment liquid storage region 32a, 32b.

  In the disposable processing case 50 having such a structure, the processing liquid storage region 32 is provided in the peripheral wall portion 18 of the container main body 14, thereby appropriately supporting the bottom wall portion 20 of the rigid container main body 14. The processing case 50 can be stably placed on a table or the like even after the processing liquid is discharged from the processing liquid storage areas 32a and 32b and the storage films 30a and 30b are crushed. Can be mounted.

  Next, FIGS. 10 to 11 show a disposable processing case 60 as a fourth embodiment of the present invention. On the outer surface of the bottom wall portion 20 of the container body 14 in the processing case 60, four storage films 30a, 30b, 30c, and 30d each having a substantially cup shape with a bottom are fixed in fluid tightness at the periphery of the opening, respectively. In total, four processing storage areas 32a, 32b, 32c, and 32d are formed. Further, these four processing storage areas 32a, 32b, 32c, and 32d can be connected to the lens housing area 12 through the communication port 34 provided with the diaphragm 36 provided in the bottom wall portion 20 of the processing case 60. It is said that.

  Further, on the bottom side of the container body 14, a support cylinder portion 62 having a cylindrical shape obtained by extending the peripheral wall portion 18 downward is integrally formed so as to protrude downward in the axial direction from the bottom wall portion 20. ing. The support cylinder portion 62 surrounds the four storage films 30a, 30b, 30c, and 30d. Accordingly, the four storage films 30a, 30b, 30c, and 30d are protected by the support cylinder portion 62 made of a hard material, and for example, damage during carrying can be prevented. Further, since the lower end in the axial direction of the support cylinder portion 62 protrudes downward from any of the storage films 30a, 30b, 30c, 30d, it is made of a hard material when placing the container body 14 on a table or the like. The container main body 14 can be stably supported by the lower end surface of the support cylinder portion 62, and after any of the storage films 30 a, 30 b, 30 c, 30 d is crushed, the support cylinder portion 62 allows the container main body 14 to be supported. The main body 14 can be stably placed on a table or the like.

  Further, in the present embodiment, a hard lid 66 made of the same material as that of the container body 14 is employed as a lid member that covers the upper opening portion of the container body 14. The lid 66 has an inverted cup shape, and the peripheral wall 62 is detachably screwed to the opening of the peripheral wall 18 of the container body 14. The upper bottom 64 of the lid 66 is provided with a vent hole 70 at the center. Then, a permeable membrane 72 is superimposed on the upper surface of the upper bottom portion 64 so as to cover the vent hole 70 and is attached so as not to be peeled off.

  This permeable membrane 72 is a porous membrane having non-hydrophilicity (hydrophobicity) that allows the passage of air but prevents the passage of the stored processing liquid, and more preferably permeates harmful dust and bacteria. Those having a pore diameter or a porous structure capable of preventing the above are employed. Specifically, for example, a PTFE stretched porous membrane can be mentioned, but various other known porous structures can be employed regardless of natural or synthetic.

  In the disposable processing case 60 having the lid 66 as described above, after the lid 66 is removed from the container main body 14, the lid 66 can be firmly fixed to the container main body 14 and securely resealed. I can do it. Moreover, the container main body 14 is sealed with the lid 66 because the permeable membrane 72 prevents the bacterial contamination and allows the exhaust from the lens housing region 12 through the vent hole 70 to the outside. In the state, any one of the storage films 30a, 30b, 30c, and 30d is pressed, and the processing liquids 38a, 38b, 38c, and 38d stored in the processing liquid storage areas 32a, 32b, 32c, and 32d are moved into the lens storage area 12. It can be introduced into. That is, when the treatment liquid 38 is introduced into the lens housing region 12, excess air in the lens housing region 12 is discharged to the outside through the vent hole 70 and the permeable film 72, and bacteria in the lens housing region 12 are discharged. Contamination can be prevented more advantageously, and spilling of the processing liquid 38 to the outside can be more reliably prevented.

  Next, FIGS. 12 to 13 show a disposable processing case 80 as a fifth embodiment of the present invention.

  In the disposable processing case 80 of the present embodiment, a plurality of processing liquid storage regions 32 are provided on the outer surface of the bottom wall portion 20 of the container body 14 in the disposable case 60 according to the fourth embodiment. The plurality of processing liquid storage regions 32 are provided on the outer surface of the lid body 66.

  The lid 66 is integrally formed with a guide tube portion 82 that protrudes upward from the outer peripheral edge with a cylindrical shape, and these guide tube portions 82 form treatment liquid storage regions 32a and 32b. The storage films 30a and 30b are surrounded and protected. Furthermore, a pressing plate 84 having a disk shape having an outer diameter slightly smaller than the inner diameter is fitted in the guide cylinder portion 82, and is arranged in a state of spreading in a direction perpendicular to the axis.

  In order to suppress the irregular displacement of the pressing plate 84, a guide rail or a guide groove for guiding the pressing plate 84 in the axial direction may be formed on the inner peripheral surface of the guide tube portion 82, for example. Further, the pressing plate 84 may be formed independently of the storage films 30a and 30b, but in this embodiment, the outer end portions of the storage films 30a and 30b are fixed to the inner surface of the pressing plate 84, The detachment of the pressing plate 84 is prevented.

  Then, by pressing the pressing plate 84 toward the lower side (upper bottom 64 side) in the guide cylinder portion 82, the plurality of storage films 30a and 30b can be pressed simultaneously. As a result, the pressure is increased in the plurality (two in the present embodiment) of the processing liquid storage regions 32a and 32b, and the partition wall 36 that seals the communication port 34 penetrating the upper bottom portion 64 of the lid 66 is broken. Thus, the processing liquids 38a and 38b filled in the processing liquid storage areas 32a and 32b are introduced into the lens storage area 12 almost simultaneously through the communication ports 34 and 34, respectively.

  A vent hole 70 in which the permeable membrane 72 is assembled in a blocked state is formed in the upper bottom portion 64 of the lid 66 so as to avoid the position covered with the storage membrane 30. The pressing plate 84 is also provided with a vent hole 71 so as to avoid the position covered with the storage film 30. As a result, the lens housing region 12 of the container body 14 covered with the lid 66 is allowed to supply and discharge air to and from the external space through the vent holes 70 and 71.

  In the disposable processing case 80 having such a structure, the pressing plate 84 is pressed in the axially downward direction along the guide tube portion 82 to be accommodated in the pair of processing liquid storage regions 32a and 32b, respectively. The processing liquids 38a and 38b can be simultaneously introduced into the lens housing region 12 by a simple operation.

  In the present embodiment, the pressing plate 84 is pressed from above while the processing case 80 is placed on the table with the lens housing region 12 substantially sealed with the lid 66. By simple and stable operation, the processing liquids 38a and 38b respectively stored in the pair of processing liquid storage areas 32a and 32b can be introduced into the lens storage area 12 at the same time. Thereby, the ease of use of the processing case 80 can be greatly improved.

  Next, FIGS. 14 to 15 show a disposable processing case 90 as a sixth embodiment of the present invention. In the processing case 90, an inner storage film 91 having a relatively small cup shape is disposed at the central portion of the bottom wall portion 20 of the container body 14. And the process liquid storage area | region 32a which accommodated the process liquid 38a is formed because the opening part of this inner side storage film 91 adheres fluid tightly with respect to the outer surface of the bottom wall part 20. As shown in FIG.

  In addition, an outer reservoir film 92 having a cup shape slightly larger than the inner reservoir film 91 is disposed outside the inner reservoir film 91 in the bottom wall portion 20 so as to cover the inner reservoir film 91 from the outside. Yes. And the process liquid storage area | region 32b which accommodated the process liquid 38b is formed when the opening peripheral part of this outer side storage film | membrane 92 adheres to the outer peripheral part of the outer surface of the bottom wall part 20 fluid-tightly. .

  In such a disposable processing case 90 of the present embodiment, the volume of the processing liquid storage area 32b formed on the outer peripheral side is sufficiently larger than the volume of the processing liquid storage area 32a formed in the central portion. It becomes possible to set. Further, since the inner and outer reservoir films 91 and 92 are formed on the same central axis on the lower surface of the bottom wall portion 20 of the container body 14, stability when the processing case 90 is placed on a table or the like is achieved. It can be advantageously secured.

  As mentioned above, although one embodiment of the present invention has been described in detail, these are merely examples, and the present invention is not limited in any way by the specific description in the embodiment, and to the knowledge of those skilled in the art. The present invention can be implemented in various modifications, corrections, improvements, and the like based on the above, and all such embodiments are included in the scope of the present invention without departing from the spirit of the present invention. It goes without saying that.

  For example, in the above-described embodiment, the lens housing region 12 is in an empty state before the use of the disposable processing case. However, the present invention is not limited to this. Specifically, for example, as shown in FIG. 16, the contact lens 22 is housed in the lens housing region 12 in a state of being immersed in a preserving liquid or processing liquid 38 a as a processing liquid. Also good. Further, for example, as shown in FIG. 17, a predetermined processing liquid 38 a may be stored in the lens storage region 12 in advance.

  Further, the number of the processing liquid storage areas 32 formed is not limited in any way. For example, as shown in FIGS. 16 and 17, the processing liquid storage areas 32 pre-filled with the processing liquid 38 are provided. Only one may be formed. Alternatively, it is possible to form five or more treatment liquid storage regions 32, and the formation regions are formed by the outer surface of the bottom wall 20 of the container body 14, the outer surface of the peripheral wall 18, and the outer surface of the lid 66. It may be formed at a plurality of locations. For example, when used for a disposal type contact lens that is changed every week, seven treatment liquid storage regions 32 are formed, and each of them is filled with a storage liquid as a treatment liquid, and one is stored every day. It is possible to sequentially use the storage solutions provided by filling the processing solution storage area 32 one by one.

  In addition, as shown in FIG. 18, the two processing liquid storage areas 32 a and 32 b are formed in a laminated form, and a communication port is formed in the partition wall portion where the two processing liquid storage areas 32 a and 32 b are stacked. 34 may be formed. Thus, by pressing only the storage film 30b that defines the outer processing liquid storage area 32b, pressure is applied to the processing liquids 38a and 38b filled in both the processing liquid storage areas 32a and 32b, and the communication holes Both of the treatment liquids 38a and 38b can be efficiently and easily introduced into the lens accommodating region 12 through the reference numerals 34 and 34.

  Furthermore, in the present invention, the present invention can be applied to a disposable processing case in which a plurality of lens housing regions 12 are formed. As an example, the housing regions 12a and 12b of a pair of left and right contact lenses 22a and 22b are provided. An example in which the present invention is applied to a product is shown in FIG. Such a processing case includes a container body 14 having a generally cylindrical shape, and the hollow interior of the container body 14 is partitioned by a partition wall at the center in the axial direction, whereby a right lens housing area 12a and a left lens container are provided. A storage area 12b is formed. In addition, a pair of lids 66a and 66b are detachably mounted, for example, by a screwing structure so as to cover the openings on both sides in the axial direction of the container body 14, and each of the storage areas 12a and 12b has a sealed structure. It has come to be. In the present embodiment, similarly to the processing case shown in FIG. 17, bag-like storage films 30a and 30b are attached to the outer surfaces of the lids 66a and 66b, and are used for the lens housing regions 12a and 12b. Treatment liquid storage areas 32a and 32b are formed.

  In addition, the disposable processing case according to the present invention has no distinction between myopia, hyperopia, presbyopia, etc., and there is no distinction between a disposal type and a normal type, and there is no distinction between soft contact lenses and hard contact lenses. Needless to say, any of the contact lens applications can be applied.

  In addition, the disposable processing case according to the present invention can be provided as a simple lens care product without accommodating the contact lens 22 in the lens accommodation area 12, but in addition, the contact lens 22 is previously provided in the lens accommodation area 12. Can be used as a contact lens lens container for transporting or providing contact lenses from a manufacturer to a medical institution or to a user.
