Description

  The present invention relates to a contact lens container for housing a contact lens, and more particularly to a contact lens container used for both cleaning and storage of a contact lens.

  2. Description of the Related Art Conventionally, contact lenses are provided that are attached to the surface of the cornea for the purpose of correcting myopia, hyperopia, astigmatism, presbyopia, and the like. In such a contact lens, protein or lipid secreted from the eye or dust in the air adheres to the surface of the contact lens during wearing, and thus a reduction in translucency and wearing feeling cannot be avoided. Therefore, it is necessary to periodically remove contaminants such as proteins, lipids, and dust attached to the contact lens.

  By the way, conventionally, contact lenses have been generally washed by a person (rubbing) by directly rubbing with a finger using a dedicated cleaning solution. Therefore, when the nail is extended or the fingertip is rough, the contact lens may be damaged by scrubbing.

  Further, since the contact lens is small, there is a risk that the contact lens may be lost if it is accidentally dropped during scrubbing.

  Furthermore, since there are individual differences in the strength of the force to pinch the contact lens between fingers and the time required for scrubbing, there is also a problem that the cleaning effect tends to vary.

  Furthermore, since the finger is directly rubbed, it is necessary to clean the fingertips in advance and remove dirt such as oils and fats before cleaning the contact lens. Therefore, when the contact lens is cleaned on the go, there is a problem that a place for cleaning the fingertip must first be searched.

  In view of such a problem, in Patent Document 1 and Patent Document 2, a contact lens is sandwiched between a pair of elastic pads, and one of the pair of elastic pads is rotated relative to the other to A contact lens cleaner for cleaning a contact lens by rubbing against the contact lens has been proposed.

  However, since the contact lens cleaners described in Patent Document 1 and Patent Document 2 are only intended for cleaning contact lenses, when rinsing the contact lenses, the contact lenses can be removed with fingers or tweezers. It is necessary to take it out. Therefore, when taking out the contact lens, the contact lens may be contaminated or lost. In addition, if the cleaning liquid is discharged with the contact lens housed in the contact lens cleaner, the contact lens may flow out together with the cleaning liquid. In addition, since the contact lens is kept sandwiched between the cleaning surfaces, the contact lens is deformed and stressed, which is not suitable for storing the contact lens, and a separate contact lens storage container is required. There is also the problem of becoming.

US Pat. No. 4,559,662 Japanese Utility Model Publication No. 61-31295

  Here, the present invention has been made in the background as described above, and the problem to be solved is that both cleaning and rinsing of the contact lens can be performed efficiently, and the contact lens An object of the present invention is to provide a contact lens container having a novel structure that can be stored.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  The present invention relates to a contact lens container in which a contact lens is immersed in a lens processing liquid, and (a) a container body in which a storage recess for storing the contact lens and the lens processing liquid is formed; and (b) formed in the container body. A lid that covers the opening of the housing recess, and (c) lens processing provided in at least one of the lid and the container body, and the opening of the housing recess formed in the container body is covered by the lid. A drainage passage that can drain the liquid to the outside; (d) a valve mechanism that switches the drainage passage between a communication state in which the lens processing liquid can be drained and a blocking state in which the lens processing liquid cannot be drained; A shut-off state holding mechanism that holds the liquid passage in a shut-off state; and (f) a pair of elastic pads that are provided between the opposing surfaces of the container body and the lid and sandwich the contact lens housed in the housing recess from both the front and rear sides. , (G The relative position of the lid with respect to the container body can be changed, and the cleaning position where the pair of elastic pads are brought close to each other and the contact lens is sandwiched between the pair of elastic pads is separated from the pair of elastic pads. A position selection mechanism for selectively setting a storage position in which the contact lens is not sandwiched between the pair of elastic pads; and (h) in the cleaning position, the container body and the lid body are relatively displaced, whereby the contact lens is paired. A relative displacement mechanism for scrubbing between the elastic pads is provided.

  In such a contact lens container structured according to the present invention, the contact lens is moved to a pair of elastic pads by relatively displacing the container body and the lid at a cleaning position where the contact lens is sandwiched between the pair of elastic pads. It becomes possible to scrub between.

  In addition, since the drainage passage is in a communicating state, the lens processing liquid can be discharged while the opening of the housing recess formed in the container body remains covered by the lid. By appropriately setting the size and shape of the liquid passage, it is possible to discharge only the lens processing liquid while preventing the contact lens from flowing out without removing the contact lens when rinsing the contact lens. Is possible.

  Furthermore, by maintaining the discharge passage in a cut-off state, it is possible to store the contact lens while preventing the unexpected liquid leakage while being immersed in the treatment liquid.

  Therefore, in the contact lens container having the structure according to the present invention, both cleaning and rinsing of the contact lens can be performed efficiently and the contact lens can be stored.

  In addition, the drainage passage in the present invention may be in a communication state or a shut-off state at the cleaning position. In the present invention, the drainage passage may be formed in either the lid body or the container main body, or may be provided in both of them. Alternatively, the drainage passage may be formed in cooperation by communicating the lid and the passage provided in the container body.

  In the present invention, it is desirable that a valve mechanism for opening and closing the drainage passage is configured by relative displacement of the lid with respect to the container body. As a result, the valve mechanism can be realized with a simple structure. The relative displacement of the lid with respect to the container body may be performed in the direction in which the central axis of the container body extends, that is, in the opening direction of the housing recess formed in the container body. It may be performed around the axis.

  Further, in the present invention, when a valve mechanism is configured in which the drainage passage changes from the shut-off state to the communication state when the lid is pushed in the opening direction of the housing recess formed in the container body, the lid It is desirable to provide a pushing direction displacement preventing means for preventing displacement of the container body in the pushing direction. As a result, it is possible to prevent the valve mechanism from being switched without the knowledge and the drainage passage from being switched to the communicating state. As a result, when the contact lens container of the present invention is placed in the bag, it is possible to prevent the treatment liquid from leaking from the contact lens container and getting wet in the bag.

  Therefore, the pushing direction displacement prevention means may be configured by an outer cover member that is attached to the container body and covers the lid body, and is sandwiched between the container body and the lid body in the displacement direction of the lid body. You may be comprised by the lock spacer.

  In the present invention, it is desirable that each of the pair of elastic pads has a sponge structure. Accordingly, when the contact lens is rubbed, the treatment liquid can be brought into contact with the central portion of the contact lens. As a result, the contact lens can be more efficiently cleaned. The elastic pad may be a rubber elastic body that does not contain water. In this case, it is possible to reduce the amount of processing liquid required.

  Furthermore, in the present invention, it is desirable that the contact lens can be scrubbed between the pair of elastic pads by rotating the lid around the central axis of the container body. As a result, the contact lens can be scrubbed around the lens center. As a result, the container structure is simplified as compared with the case where the contact lens is rubbed so as to reciprocate in the radial direction of the contact lens.

  Therefore, when the configuration as described above is adopted, it is desirable that a relative rotation amount limiting mechanism for limiting the relative rotation amount of the lid body with respect to the container body is provided. Thereby, it is possible to force the scrubbing by the reciprocating rotation operation. As a result, the operation becomes easier and the cleaning efficiency can be improved as compared with the case of scrubbing by rotating in one direction.

  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.

  1 to 3 show a contact lens container 10 as a first embodiment of the present invention. The contact lens container 10 includes a container body 12 and a lid body 14 that covers the opening of the container body 12. In the following description, the vertical direction means the vertical direction in FIGS. 2 and 3 in principle.

  More specifically, the container body 12 of the present embodiment is formed of a hard synthetic resin material such as polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, etc., and has a cylindrical wall 16 and a bottom wall 18 as a whole. It is a bottom cylindrical shape. Thereby, in the container main body 12 of this embodiment, the accommodation recessed part 20 extended straightly with a substantially constant circular cross section is formed so that it may open upwards.

  An elastic pad 22 is provided at the bottom of the housing recess 20. The elastic pad 22 is made of polyurethane, acrylic resin, methacrylic resin, silicone rubber, or the like, and particularly in this embodiment, has a structure in which open cells are formed like a sponge. Absorbability is largely secured.

  In addition, the elastic pad 22 has a thick disk shape as a whole, and in this embodiment, a spherical recess in which the opening-side surface (upper surface) of the housing recess 20 is recessed toward the opening side of the housing recess 20. The curved surface 24 is shaped.

  On the other hand, the lid body 14 is configured to include a fixed side lid member 26 fixedly assembled to the container body 12 and a movable side lid member 28 assembled relative to the fixed side lid member 26 so as to be relatively displaceable. Yes. The fixed-side lid member 26 is formed of the same material as that of the container body 12 and has a large-diameter cylindrical shape as a whole.

  Therefore, the fixed-side lid member 26 of the present embodiment has a stepped surface 30 formed in the axially intermediate portion on the inner peripheral surface side, and a thick wall having a thick cylindrical shape above the stepped surface 30. On the other hand, a cylindrical portion 32 is formed on the lower side of the step surface 30 with a thin cylindrical shape.

  The fixed-side lid member 26 having such a structure is fixed to the container main body 12 on the opening end side of the housing recess 20 by the thin cylindrical portion 34 being externally inserted into the container main body 12 and screwed. Can be assembled to.

  On the other hand, the movable side cover member 28 is formed of the same material as that of the container body 12 and has a cylindrical block shape as a whole. Therefore, in the present embodiment, an elastic pad 36 is provided at one end of the movable side cover member 28 in the axial direction. The elastic pad 36 is formed of the same material as the elastic pad 22 provided on the bottom of the housing recess 20 and has similar characteristics, and its lower end surface is convex outward in the axial direction. A spherical convex curved surface 38 is formed.

  Further, in the present embodiment, a stopper piece 40 that protrudes radially outward is formed on the other end side in the axial direction of the movable-side lid member 28, and in particular, the stopper piece 40 of the present embodiment. The outer diameter of the fixed lid member 26 is larger than the outer diameter thereof.

  Furthermore, in this embodiment, a plurality (four in this embodiment) of drainage passages 42 are formed for the movable side lid member 28. Therefore, in the present embodiment, each drainage passage 42 is substantially constant with respect to the lower end of the axial passage 44 extending straight downward from the upper end surface of the movable side cover member 28 with a substantially constant circular cross section. An axially perpendicular passage 46 is connected in a circular cross section that extends straight toward the outer periphery. One opening is formed on the upper end surface of the movable lid member 28, while the other opening is movable. It is formed on the outer peripheral surface of the side lid member 28. In the present embodiment, the inner diameter dimension of each axially perpendicular passage 46 is smaller than the inner diameter dimension of the axial passage 44, but is not limited thereto, and does not need to be a circular cross-sectional passage. In the present embodiment, the four drainage passages 42 are arranged at equal intervals in the circumferential direction.

  The movable-side lid member 28 having such a structure is inserted into the thick-walled cylindrical portion 32 of the fixed-side lid member 26 from the end where the elastic pad 36 is provided. On the other hand, it is assembled so as to be capable of relative displacement in the axial direction. Since the movable side lid member 28 is assembled to the fixed side lid member 26 in this way, the opening of the housing recess 20 formed in the container body 12 is covered with the lid body 14. is there.

  Therefore, in the present embodiment, a pair of engaging protrusions 48 are provided at an appropriate interval in the axial direction with respect to the cylindrical outer peripheral surface of the movable side lid member 28, while the fixed side lid member 26 is provided. Three engagement grooves 50, 52, and 54 are formed at appropriate intervals in the axial direction with respect to the inner peripheral surface of the thick-walled cylindrical portion 32 in FIG.

  Then, with the movable side cover member 28 inserted and arranged in the fixed side cover member 26 as described above, the pair of engagement protrusions 48 and 48 are fitted into two engagement grooves adjacent in the axial direction. ing. As a result, the axial position of the movable side lid member 28 with respect to the fixed side lid member 26 is defined, and the movable side lid member 28 is held at the defined position.

  Each of the pair of engaging protrusions 48 and 48 is formed of a conventionally known rubber material or elastic synthetic resin material, and is adhered to the outer peripheral surface of the movable side lid member 28 by bonding with an adhesive or the like. It is fixed. When a force for axially displacing the movable side lid member 28 is applied, the pair of engaging protrusions 48 and 48 are each elastically deformed, whereby the fixed side of the movable side lid member 28 is fixed. The axial position with respect to the lid member 26 can be changed. The engaging protrusions 48 and 48 may be integrally formed on the outer peripheral surface of the movable side lid member 28 if the material, shape, size, etc. of the fixed side lid member 26 and the movable side lid member 28 are appropriately set. Is possible.

  Further, in a state where the pair of engaging protrusions 48 and 48 are fitted in two engaging grooves adjacent in the axial direction, the outer peripheral surface of the movable side lid member 28 and the thick cylindrical portion 32 in the fixed side lid member 26. It is desirable that the inner peripheral surface is in close contact. Thereby, the sealing of the container is realized at the storage position shown in FIG. 2, but in addition, for example, the engagement protrusion 48 is formed between the radially overlapping surfaces of the movable side lid member 28 and the fixed side lid member 26. Alternatively, it is also possible to achieve sealing of the container by mounting an O-ring or the like at a position away from the engagement grooves 50, 52, and 54.

  Further, as described above, the movable-side lid member 28 is inserted into the fixed-side lid member 26 so that the elastic pad 36 provided on the movable-side lid member 28 and the elastic pad 22 provided on the container body 12 are provided. Are arranged to face each other in the facing direction of the bottom wall 18 of the container main body 12 and the movable side lid member 28.

  Therefore, in the present embodiment, the pair of engagement protrusions 48, 48 provided on the movable-side lid member 28 is fitted into the upper engagement groove 50 and the middle engagement groove 52, and the movable side The contact lens 56 positioned between the elastic pad 36 provided on the lid member 28 and the elastic pad 22 provided on the container body 12 is not sandwiched between the pair of elastic pads 22 and 36. On the other hand, in a state where the pair of engaging protrusions 48, 48 provided on the movable side cover member 28 are fitted in the middle engaging groove 52 and the lower engaging groove 54, the movable side cover The contact lens 56 positioned between the elastic pad 36 provided on the member 28 and the elastic pad 22 provided on the container body 12 is sandwiched between the pair of elastic pads 22 and 36. . As is clear from this, in the present embodiment, the position selection mechanism is configured to include a pair of engagement protrusions 48 and 48 and three engagement grooves 50, 52 and 54.

  Further, in the present embodiment, the drainage passage is in a state where the pair of engaging protrusions 48, 48 provided on the movable lid member 28 are fitted in the upper engaging groove 50 and the middle engaging groove 52. The other opening of 42 is covered fluid-tightly by the thick-walled cylindrical portion 32 of the fixed-side lid member 26, whereby the housing recess 20 whose opening is covered with the lid body 14 is removed from the external space. On the other hand, in a state in which the pair of engaging protrusions 48, 48 provided on the movable side lid member 28 are fitted in the middle engaging groove 52 and the lower engaging groove 54, The other opening of the drainage passage 42 is not fluid-tightly covered by the thick-walled cylindrical portion 32 of the fixed-side lid member 26, so that the accommodation recess 20 in which the opening is covered with the lid body 14. Is communicated with the external space through the drainage passage 42. That. That is, in the present embodiment, the movable side cover member 28 is disposed in the axial direction (accommodation of the container main body 12 with respect to the fixed side cover member 26, and thus the container main body 12 to which the fixed side cover member 26 is fixedly assembled. A valve mechanism that opens and closes the drainage passage 42, that is, a valve mechanism that switches the drainage passage 42 between a communication state and a shut-off state by being relatively displaced in the opening direction of the recess 20). In this embodiment, the pair of engaging projections 48, 48, the upper engaging groove 50, and the middle engaging groove 52 constitute a shut-off state maintaining mechanism.

  In the contact lens container 10 having such a structure, the cleaning liquid as the lens processing liquid 58 and the contact lens 56 are placed in the housing recess 20, and then the lid 14 covers the opening of the housing recess 20. In this state, when the stopper piece 40 provided on the movable side lid member 28 is not in contact with the upper end surface in the axial direction of the fixed side lid member 26, the movable side lid member 28 is moved relative to the fixed side lid member 26. The stopper piece 40 is pushed in until it comes into contact with the upper end surface in the axial direction of the fixed-side lid member 26. As a result, the pair of elastic pads 22 and 36 are moved close to each other, and the contact lens 56 is sandwiched between the pair of elastic pads 22 and 36. In this state, the contact lens 56 is rubbed between the pair of elastic pads 22 and 36 by rotating the movable side cover member 28 around the central axis with respect to the container body 12. As is clear from this, in the present embodiment, the relative displacement mechanism is configured including the movable side lid member 28 and the fixed side lid member 26.

  In addition, the used cleaning liquid (lens processing liquid 58) is discharged to the outside through the drainage passage 42 in a communicating state. At this time, in this embodiment, since the contact lens 56 is sandwiched between the pair of elastic pads 22 and 36, the cleaning liquid (lens processing liquid 58) is discharged when the contact lens 56 discharges the cleaning liquid (lens processing liquid 58). 58), it can be prevented from being poured out together.

  Furthermore, after the cleaning and rinsing of the contact lens 56 is completed, a storage solution as the lens processing solution 58 is put into the housing recess 20. The storage solution (lens processing solution 58) may be put through the drainage passage 42 that is in a communicating state, or may be put in a state in which the lid 14 is removed from the container body 12.

  Then, in order to make the stopper piece 40 provided on the movable side lid member 28 not in contact with the upper end surface in the axial direction of the stationary side lid member 26, the movable side lid member 28 is fixed to the stationary side lid member 26. Displace in the pulling direction. As a result, the pair of elastic pads 22 and 36 are displaced apart so that the contact lens 56 is not sandwiched between the pair of elastic pads 22 and 36 and the drainage passage 42 is shut off. As a result, it is possible to store the contact lens 56 by immersing the contact lens 56 in a storage solution (lens processing solution 58) in a state where the housing recess 20 is sealed.

  Therefore, in the contact lens container 10 having the above-described structure, the contact lens 56 can be efficiently cleaned and rinsed, and the contact lens 56 can be stored.

  In particular, in the contact lens container 10 according to the present embodiment, the contact lens 56 is rubbed between the pair of elastic pads 22 and 36. It is possible to prevent sticking. Further, the contact lens 56 is not lost during the scrubbing.

  In addition, since the axial position of the movable lid member 28 relative to the fixed lid member 26 is defined, the force for sandwiching the contact lens 56 between the pair of elastic pads 22 and 36 is made substantially constant. Is possible. Thereby, it becomes possible to make it difficult for variations in the cleaning effect to occur.

  In the present embodiment, the stopper piece 40 protrudes radially outward from the outer peripheral surface of the fixed-side lid member 26, so that the stopper piece 40 is fixed to the upper end surface in the axial direction of the fixed-side lid member 26. The operation of displacing the movable-side lid member 28 from the state of being in contact with the head can be advantageously realized.

  Furthermore, in this embodiment, since the drainage passage 42 is in a communicating state with the movable side cover member 28 pushed in, the elastic pads 22 and 36 are washed when the contact lens 56 is washed. When the contact lens 56 is sandwiched between them, the inside of the contact lens container 10 is in communication with the external space, and when the contact lens 56 is sandwiched between the elastic pads 22 and 36, the pressure in the contact lens container 10 becomes resistance. This can also be prevented.

  Next, a contact lens container 60 as a second embodiment of the present invention will be described based on FIGS. 4 and 5. In the second embodiment described below and third to sixth embodiments described later, members and parts having the same structure as the first embodiment are the same as those in the first embodiment. The detailed description is abbreviate | omitted by attaching | subjecting a code | symbol.

  More specifically, the contact lens container 60 of the present embodiment has a lid 14 inserted through the container main body 12 as compared with the contact lens container (10) of the first embodiment. The opening of the formed accommodation recess 20 is covered. Further, the lid body 14 of the present embodiment has a large-diameter portion on the upper end side in the axial direction, and a small-diameter portion on the lower end side in the axial direction, whereby a through hole 62 described later is pushed into the lid body 14. Even the position is not covered. Furthermore, in the present embodiment, a plurality of through holes 62 (two or more in the present embodiment) penetrating in the direction perpendicular to the axis with respect to the cylindrical wall 16 of the container body 12 are formed. The outer lid 64 fitted from the outer peripheral surface side is covered fluid-tightly. The outer lid 64 is not particularly limited as long as the outer lid 64 can cover the through-hole 62 in a fluid-tight manner, but a rubber elastic body is preferably employed. Further, as the outer lid 64, an annular elastic ring without a protrusion that fits into the through hole 62 is adopted, and the outer opening of each through hole 62 is brought into close contact with the outer peripheral surface of the cylindrical wall 16 based on the elasticity. You may make it cover.

  In the contact lens container 60 having such a structure, the pair of elastic pads 22 and 36 are brought close to each other by pushing the lid body 14 against the container body 12, and the contact lens is formed by the pair of elastic pads 22 and 36. In this state, the contact body 56 is rubbed between the pair of elastic pads 22 and 36 by rotating the lid 14 with respect to the container body 12 in this state.

  Further, the used cleaning liquid (lens processing liquid 58) is discharged to the outside through the through hole 62 after the outer lid 64 is removed and the through hole 62 is brought into a communication state.

  Furthermore, after the cleaning and rinsing are completed, the outer lid 64 is fitted, so that the through hole 62 is again blocked and the accommodation recess 20 is sealed, and then the lid 14 is removed. A storage solution (lens processing solution 58) is added, and the contact lens 56 is stored in a state immersed in the storage solution (lens processing solution 58).

  Therefore, also in the contact lens container 60 of the present embodiment, the same effect as that of the first embodiment can be obtained.

  As shown in FIG. 6, the position of the through hole 62 provided in the cylindrical wall 16 of the container body 12 is appropriately adjusted, and the first implementation is performed according to the position where the lid 14 is pushed into the container body 12. It is also possible to constitute a valve mechanism that opens and closes the through hole 62 with the lid body 14 as in the embodiment.

  That is, as shown in FIG. 6, one opening is formed on the outer peripheral surface of the lid body 14 with respect to the lid body 14, and the other opening is formed on the lower end surface of the large-diameter portion of the lid body 14. The drainage passage 63 may be formed by forming the communication hole 61 in which the communication hole 61 is formed and the communication hole 61 and the through hole 62 cooperate. Specifically, as shown in FIG. 6, the communication hole 61 is not connected to the through-hole 62 at a position where the lid body 14 is not pushed into the container body 12 (position where it is pulled out). However, the drainage passage 63 is shut off, while the lid body 14 is pushed into the container body 12 as shown in FIG. 7, and the circumferential position of the lid body 14 with respect to the container body 12 is set appropriately. In this position, the communication hole 61 may be connected to the through hole 62 so that the drainage passage 63 is in a communication state. As a result, the lid 14 is displaced relative to the container body 12 to open and close the drainage passage 63, that is, to configure a valve mechanism that switches the drainage passage 63 between a communication state and a blocking state. Become. The other opening of the communication hole 61 does not need to be formed on the lower end surface of the large-diameter portion of the lid body 14, and may be formed on the outer peripheral surface of the small-diameter portion of the lid body 14, for example.

  Next, a third embodiment of the present invention will be described based on FIGS. Compared to the contact lens container (10) of the first embodiment, the contact lens container 66 of the present embodiment does not have the drainage passage 42 formed on the movable side cover member 28. Instead, the contact lens container 66 is movable. A taper portion 70 having a tapered surface 68 that is gradually reduced in diameter as it goes upward in the axial direction is provided at an axially intermediate portion of the side lid member 28. Thereby, the movable side cover member 28 of the present embodiment has a small diameter portion 72 in which the upper end side in the axial direction has a smaller diameter than the lower end side in the axial direction. In particular, in the present embodiment, the small-diameter portion 72 of the movable-side lid member 28 has an outer diameter that is smaller than the inner-diameter dimension of the thick-walled cylindrical portion 32 of the fixed-side lid member 26.

  In addition, the movable side lid member 28 of the present embodiment is integrally provided with an outer cylinder 74 having a large-diameter cylindrical shape with respect to the stopper piece 40, and the outer cylinder 74 is configured to be movable side lid member 28. Is slidable with respect to the outer peripheral surface of the fixed-side lid member 26 in a state of being inserted into the fixed-side lid member 26. Further, a tapered surface 76 corresponding to the tapered surface 68 formed on the movable side cover member 28 is formed on the inner peripheral edge of the lower end of the thick tube portion 32 in the fixed side cover member 26.

  In the contact lens container 66 having such a structure, when the movable side cover member 28 is pushed in, the contact lens 56 is sandwiched between the pair of elastic pads 22 and 36 and the movable side cover member is also sandwiched. A gap 78 is formed between the small-diameter portion 72 and the tapered portion 70 of the 28 and the thick-walled cylindrical portion 32 of the fixed-side lid member 26 so that the central hole 79 of the thick-walled tubular portion 32 is in communication. The used cleaning liquid (lens processing liquid 58) can be discharged through the communication hole 79 and the through hole 80 formed in the stopper piece 40. Although not clearly shown in the drawings, a plurality of through holes 80 are formed at appropriate intervals in the circumferential direction.

  On the other hand, when the movable cover member 28 is pulled out, the pair of elastic pads 22 and 36 do not sandwich the contact lens 56, and the small diameter portion 72 and the tapered portion 70 of the movable cover member 28 are fixed to the fixed side. Of the gap 78 formed between the thick cylindrical portion 32 of the lid member 26, a portion formed between the tapered portion 70 of the movable side lid member 28 and the thick cylindrical portion 32 of the fixed side lid member 26. As a result, the central hole 79 of the thick-walled cylindrical portion 32 is blocked, and the housing recess 20 whose opening is sealed with the lid 14 is blocked from the outside.

  As is apparent from the above description, in this embodiment, the drainage passage is configured by the center hole 79 and the through hole 80 of the thick-walled cylindrical portion 32.
