Description

  The present invention relates to a liquid processing apparatus used for liquid processing of contact lenses, precious metal products and the like for the purpose of cleaning and sterilization.

  Conventionally, when a change in adhesion of foreign matter or oxidation becomes a problem during use of an article, the article is immersed in an appropriate treatment liquid such as a cleaning liquid, a sterilizing liquid, or a reaction liquid to perform a liquid treatment. Yes. For example, in the case of contact lenses, proteins, fats, calcium, etc. are likely to adhere during use, and if they are left unattended, the appearance will deteriorate, and there is a concern about bacterial growth, eye diseases, etc. Liquid treatment such as cleaning and sterilization is required.

  By the way, a cleaning container that contains a cleaning solution to which the contact lens is immersed is generally used for such operations as cleaning the contact lens. The cleaning solution and the contact lens are put in the cleaning container and sealed with a screw cap. I was supposed to.

  However, in the cleaning container having such a conventional structure, since the cleaning liquid must be replaced every time, a liquid storage bottle is prepared separately from the cleaning container, and a predetermined amount is transferred from the liquid storage bottle to the cleaning container. It was difficult to use because it was necessary to inject the cleaning solution.

  In particular, when injecting the liquid from the liquid storage bottle into the cleaning container, the operation of injecting the treatment liquid into the cleaning container while adjusting the amount by inverting the liquid cleaning bottle has to be performed, which is troublesome. In addition, since the processing liquid must be discharged from the liquid storage bottle and simultaneously poured into a separate small cleaning container, there is a problem in that the processing liquid spills or drops at that time, so that the surroundings are easily wetted. Furthermore, there is also a problem that it is difficult to adjust the amount of liquid flowing out from the bottle while accurately guiding the processing liquid flowing out from the bottle to the small inlet of the cleaning container.

  Japanese Patent Laid-Open No. 2005-17826 (Patent Document 1) proposes a structure in which a cleaning space is integrally formed on an upper portion of a liquid storage bottle. However, if the cleaning space that can accommodate the two contact lenses on the left and right is integrally formed on the upper part of the liquid storage bottle, the liquid storage bottle is remarkably enlarged, making it difficult to carry it on a business trip or travel. In addition, when cleaning contact lenses, etc., for the purpose of improving the cleaning effect, etc., it may be necessary to shake the contact lenses while the contact lenses are immersed in the cleaning solution. There is a new problem that it must be shaken and cannot be washed in practice.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 and 2 show a contact lens cleaning apparatus 10 as a first embodiment of the present invention relating to a liquid processing apparatus. The cleaning device 10 includes a bottle 12 and a housing 14, and the housing 14 is combined with the bottle 12 so as to be detachable.

  The bottle 12 stores and stores a contact lens cleaning liquid 16 as a processing liquid, and a bottle body 18 having a hollow cylindrical shape with a bottom is employed. The upper end opening of the bottle main body 18 is a bottle neck portion 20 that protrudes upward, and a nozzle 22 is fixed to the bottle neck portion 20, thereby causing the flow to protrude upward. An outlet 23 is configured.

  The nozzle 22 has a small-diameter outlet 24 formed at the center and is opened upward, and a fitting tube portion 26 that projects downward on the outer peripheral side of the outlet 24 is integrally formed. Yes. The fitting tube portion 26 is press-fitted into the bottle neck portion 20 of the bottle body 18 and is fluid-tightly fitted, whereby the nozzle 22 is attached to the bottle neck portion 20. However, the fitting tube portion 26 may be fixed to the bottle neck portion 20 by screwing, bonding, welding, or the like.

  Further, the outlet 24 of the nozzle 22 has a small-diameter cylindrical shape and projects downward. A tube 28 is connected to the downward projecting end of the outlet 24 to form an outflow passage for the processing liquid. ing. That is, the tube 28 is accommodated in the bottle 12 and extends in the vertical direction. The upper end of the tube 28 communicates with the outside of the bottle 12 through the outlet 24, while the lower end of the tube 28 is the bottom of the bottle body 18. It is open nearby. The inner region of the bottle 12 communicates with the outside only through the outlet 24 of the nozzle 22, and the inside of the bottle 12 is made fluid-tight by closing the outlet 24.

  Furthermore, the bottle body 18 has a bottom surface 30 that can be stably placed on a mounting surface such as a flat table. Further, the bottle body 18 may be formed of a rigid material such as glass or hard resin. However, the bottle body 18 of the present embodiment has elasticity such as polyethylene terephthalate, polyethylene, polypropylene, nylon, and polyvinyl chloride. The elastic member is made of a flexible synthetic resin material. As a result, the bottle body 18 can be squeezed and deformed relatively easily by gripping it by hand and exerting a pressing force on the outer peripheral surface, and can be quickly swelled and restored to the initial shape by removing the pressing force. It has become.

  In short, even if the bottle 12 of this embodiment is not inverted, the outer peripheral surface of the bottle body 18 is pressed by hand with the outlet 24 facing upward, for example, with the bottle 12 placed on a table or the like. Thus, the internal pressure of the bottle 12 is increased, and the cleaning liquid 16 in the bottle 12 can be discharged from the outlet 24 to the outside by this pressure. In addition, at that time, the cleaning liquid 16 in the bottle 12 flows into the tube 28 from the bottom of the bottle 12 and is guided to the outlet 24 through the tube 28, so that the bottle 12 can be inverted without being inverted. In this state, the cleaning liquid 16 in the bottle 12 can be allowed to flow out from the outlet 24 with almost no excess.

  On the other hand, the housing 14 has a processing recess 32 as a processing chamber that opens upward. The outer peripheral shape and the specific structure of the housing 14 are not limited as will be understood from other embodiments described later, but in the present embodiment, the outer shape is a hemisphere as a whole.

  In addition, the housing 14 of the present embodiment is configured by assembling and fixing a cup member 34 forming the processing recess 32 to a housing body 36 formed separately from the cup member 34. The cup member 34 and the housing main body 36 are preferably formed of a hard material that is prevented from being deformed during use. For example, even if it is an elastic material such as polyethylene terephthalate, polyethylene, polypropylene, etc. It is only necessary to prevent the processing recess 32 from being deformed to a problem by adjusting.

  That is, the housing main body 36 has a hemispherical shape in which a horizontal great circle is the upper end surface, and a circular recess 38 is formed in the center of the circular upper end surface. On the other hand, the cup member 34 has a thin, generally cup shape having an outer surface that is slightly smaller than the inner surface of the circular recess 38, and is fitted into the circular recess 38 and assembled in a housed state. .

  Further, as shown in FIG. 3, at the center of the bottom of the cup member 34, a raised plate-like annular protrusion 40 is integrally formed so as to protrude downward. The annular protrusion 40 is divided at a plurality of locations on the circumference, and a communication groove 42 that connects the inner peripheral side and the outer peripheral side of the annular protrusion 40 is formed.

  Furthermore, on the outer peripheral surface of the opening side end portion of the cup member 34, outer projections 44 projecting radially outward are integrally formed at a plurality of locations on the circumference.

  When the cup member 34 is fitted into the circular recess 38 of the housing body 36, the protruding front end surface of the annular protrusion 40 of the cup member 34 is in contact with the bottom surface of the circular recess 38, and the cup member 34. The front end surface of the outer protrusion 44 is in contact with the inner peripheral surface of the opening of the circular recess 38. As a result, a gap 46 is formed between the cup member 34 and the circular recess 38 of the housing body 36 so as to extend across the entire opposing surface excluding the contact portions of the annular protrusion 40 and the outer protrusion 44. In other words, the processing recess 32 in the housing 14 has a double wall structure with the wall portion formed by the housing main body 36 and the cup member 34, and the gap 46 extends so as to extend over substantially the entire wall portion. Is formed.

  In the present embodiment, the processing recess 32 formed by the cup member 34 has a curvature radius larger than the curvature radius of the front surface of the contact lens 47 accommodated therein and the outer diameter (DIA) of the contact lens 47. The inner surface has a concave spherical bottom surface having a larger outer diameter and a cylindrical peripheral wall surface that curves from the outer peripheral portion of the bottom surface and rises upward. A circular recess 38 of the housing main body 36 is formed with an inner surface having a substantially similar shape that is slightly larger than the inner surface shape of the processing recess 32.

  In addition, a peripheral bank 48 is formed on the upper end surface of the housing main body 36 where the circular recess 38 opens, and the outer peripheral edge portion extends continuously over the entire circumference. The upper end surface surrounded by the peripheral bank 48 is formed. The central portion of the wall is lower than the peripheral bank 48 by one step. A circular recess 38 is formed in the central portion of the upper end surface that is lowered in the peripheral bank 48. In addition, the cup member 34 assembled in the circular recess 38 is sized to be accommodated in the circular recess 38 as a whole, and is located above the outer peripheral wall of the processing recess 32 formed by the cup member 34. The end surface 50 is positioned at substantially the same height (substantially on the same surface) as the upper end surface of the housing body 36 lowered in the peripheral bank 48.

  Further, the outer peripheral surface of the housing main body 36 is hemispherical, and the circular recess 38 formed inside is a shallow bottom, so that the thickness of the center of the bottom of the circular recess 38 is increased. Large dimensions are secured. A mounting recess 51 that opens downward is formed in the center of the bottom of the thick circular recess 38. The mounting recess 51 vertically penetrates the bottom of the circular recess 38, and the upper end is narrowed to open at the center of the bottom of the circular recess 38.

  Thus, as shown in FIGS. 1 and 2, the outlet portion 23 of the bottle 12 is inserted and fitted into the lower opening of the mounting recess 51 of the housing body 36. 14 is detachably attached to the bottle 12. In addition, the outlet 24 formed in the outlet 23 of the bottle 12 is fluid-tightly fitted to the mounting recess 51 of the housing main body 36 under such a mounting state. The housing 14 is connected to a gap 46 formed between the housing main body 36 and the cup member 34.

  As a result, the cleaning liquid 16 flowing out from the outlet 24 (one end) of the bottle 12 flows into the gap 46 and passes between the outer protrusions 44 and 44 from the center of the gap 46 through the communication groove 42. By flowing out from the upper opening of the gap 46, the upper end surface 50 of the outer peripheral wall of the cup member 34 is passed over and flows into the processing recess. As is clear from this, in the present embodiment, the cleaning liquid 16 supplied from the outlet 24 of the bottle 12 is removed from the upper side of the gap 46 by the gap 46 formed over substantially the entire outer peripheral wall of the processing recess 32. A liquid supply flow path that leads from the opening (the other end) to the processing recess 32 is configured.

  Further, the cleaning liquid 16 flowing out from the upper opening of the gap 46 is prevented from overflowing from the housing 14 over the peripheral bank 48 by the peripheral bank 48 protruding from the outer peripheral edge of the housing body 36. ing. That is, since the upper end surface 50 of the outer peripheral wall of the cup member 34 is lower than the peripheral dam 48, the cleaning liquid 16 that has flowed out from the upper opening of the gap 46 to the upper end surface of the housing 14 is entirely. The upper end surface 50 of the outer peripheral wall of the cup member 34 is guided to the processing recess 32.

  In addition, the treatment liquid 16 that has flowed over the upper end surface 50 of the outer peripheral wall of the cup member 34 and introduced into the processing recess 32 has a free water surface that does not exceed the upper end surface 50 of the outer peripheral wall of the cup member 34. Therefore, the air does not flow backward through the gap 46 over the upper end surface 50. Therefore, by pressing the peripheral wall of the bottle 12 by hand and allowing the processing liquid 16 to flow into the processing recess 32, a necessary amount of the processing liquid 16 can be stored in the processing recess 32. That is, in the present embodiment, the gap 46 is opened at a position higher than the prescribed liquid level of the processing recess 32 under the mounting state of the housing 14 to the bottle 12, so that the processing liquid from the processing recess 32 is opened. A flow control mechanism that prevents backflow of the gas is configured.

  In the present embodiment, the opening portion of the gap 46 serving as the liquid supply flow path on the upper end surface of the housing 14 is a peripheral bank 48 higher than that of the upper end surface 50 of the outer peripheral wall of the cup member 34. Since it is surrounded, even if a large amount of processing liquid 16 flows into the housing 14 from the bottle 12 due to a pressing operation of the bottle 12, it is prevented from overflowing from the housing 14 to the outside through the peripheral bank 48. Can be done. Even if the processing liquid 16 flows into the housing 14 from the gap 46 to the water surface higher than the upper end surface 50 of the outer peripheral wall of the cup member 34, the pressing force of the bottle 12 by hand is released, The surplus of the processing liquid 16 that gives the water level exceeding the upper end surface 50 can be quickly sucked in the backward flow direction from the gap 46 into the bottle 12. Therefore, the processing recess 32 of the housing 14 is adjusted so that an appropriate amount of the processing liquid 16 is accommodated with a water surface that does not exceed the upper end surface 50 of the outer peripheral wall of the cup member 34 at most.

  Further, a lid member 52 is assembled to the housing 14. The lid member 52 only needs to be capable of fluid-tightly covering the processing recess 32 formed in the housing 14, and the specific shape and structure are not limited as shown in other embodiments described later. In the embodiment, in consideration of the overall design including the housing 14, ease of hand-holding, and the like, the hemispherical shape is paired with the housing 14.

  Then, the housing 14 and the lid member 52 are overlapped and combined so that the upper end surface and the lower end surface, which are each great circle, abut each other. Further, corresponding portions of the outer circumferences of the housing 14 and the lid member 52 are connected by a hinge 54, and the lid member 52 is connected to the housing 14 based on the relative swinging displacement around the rotation axis by the hinge 54. Is opened and closed.

  In the open position of the lid member 52, the processing recess 32 of the housing 14 is opened to the outside. In the closed position of the lid member 52, as shown in FIG. It has come to be.

  Further, the lid member 52 is formed with a disc-shaped seal protrusion 56 that protrudes downward at the center portion on the lower end surface that is the overlapping surface with the housing 14. The outer diameter of the seal projection 56 is the same as or slightly smaller than the inner diameter of the peripheral bank 48 of the housing 14, and when the lid member 52 is closed and overlapped with the upper end surface of the housing 14, the seal The protrusion 56 enters the inner periphery of the peripheral bank 48, and the protruding front end surface (protruding lower end surface) of the seal protrusion 56 is on the peripheral wall of the cup member 34 of the housing 14 which is the upper end surface of the outer peripheral wall portion of the processing recess. It is pressed against the end face 50 to come into close contact therewith. As a result, the opening of the processing recess 32 formed in the cup member 34 is covered with the seal projection 56 in a fluid-tight manner to be a sealed region blocked from the external space.

  In the present embodiment, in the closed position of the lid member 52, the protruding tip surface of the seal projection 56 is positioned not only on the upper end surface 50 of the peripheral wall of the cup member 34 of the housing 14 but also on the inner peripheral side of the peripheral bank 48. The housing main body 36 is pressed to substantially the entire upper end surface to be brought into close contact therewith. Thereby, the opening of the gap 46 in the upper end surface of the housing 14 is hermetically sealed.

  Further, in the present embodiment, a central protrusion 58 that protrudes further downward is formed at the central portion of the protruding front end surface of the seal protrusion 56. The central protrusion 58 has a circular plateau shape with a spherical convex surface, and its outer diameter is slightly smaller than the opening diameter of the processing recess 32, so that the lid member 52 is closed. The central protrusion 58 enters inward from the opening of the processing recess 32.

  When the central protrusion 58 enters the processing recess 32, the maximum depth dimension in the central portion of the processing recess 32 sealed by the lid member 52 is reduced. Accordingly, unnecessary displacement, deformation, inversion, and the like of the contact lens 47 accommodated in the processing recess 32 can be prevented, and the central protrusion 58 is placed in the water of the cleaning liquid 16 accommodated in the processing recess 32. By projecting, the immersion state of the contact lens 47 in the cleaning liquid 16 can be expressed efficiently and more stably.

  When the contact lens 47 is cleaned using the cleaning apparatus 10 of the present embodiment having the above-described structure, first, as shown in FIG. The housing 14 is fitted and fixed. Next, the cleaning liquid 16 in the bottle 12 is caused to flow toward the housing 14 by pressing with the hand of the bottle 12 with the lid member 52 of the housing 14 being in the open position, and a predetermined amount is placed in the processing recess 32. The cleaning liquid 16 is introduced and stored.

  The amount of the cleaning liquid 16 that flows into the processing recess 32 may be an amount that allows the contact lens 47 to be completely immersed, but the inner surface of the processing recess 32 may be used for the purpose of avoiding unnecessary use. On the other hand, it is preferable to display the position of the water surface representing the specified water amount by reference with visible unevenness or printing. After the required amount of cleaning liquid 16 has flowed into the processing recess 32, the pressing force applied to the bottle 12 is removed so that the bottle 12 is elastically restored, and the amount of air corresponding to the outflow amount of the cleaning liquid 16 becomes a gap 46. From the outlet 24 and the tube 28 into the bottle 12.

  Then, before or after storing the cleaning liquid 16 in the processing recess 32, the contact lens 47 is inserted into the processing recess 32, and the contact lens 47 is immersed in the cleaning liquid 16. After that, as shown in FIG. 2, the lid member 52 is closed in the housing 14, so that the processing recess 32 in which the cleaning liquid 16 and the contact lens 47 are accommodated is sealed.

  Next, the housing 14 in which the processing recess 32 is sealed with the lid member 52 is removed from the bottle 12 to be a single body as shown in FIG. By using the housing 14 as a single unit in this manner, the small housing 14 can be easily shaken and held by hand, and the small housing 14 can be placed independently from the bottle 12 at an appropriate place. You can also leave.

  The housing 14 can also function as a cap by being attached to the outlet portion 23 of the bottle 12. However, when the housing 14 is removed and used as described above, the outlet portion 23 of the bottle 12 is covered. It is desirable to separately provide a detachable cap.

  Further, when the housing 14 is detached from the bottle 12 and placed alone in an appropriate place as described above, the bottom surface of the housing 14 is preferably a support surface that can be placed on a flat placement surface.

In addition, in order to support the housing 14 stably as needed, it is also possible to prepare a mounting table having a receiving surface shape corresponding to the bottom surface of the housing 14 and adopt such a mounting table. Then, even if the cleaning liquid 16 drops from the circular recess 38 of the housing 14, it is possible to prevent the surroundings from being soiled.

  When the necessary cleaning process is completed, the lid member 52 is opened in the housing 14, and the contact lens 47 can be taken out from the opened processing recess 32 and worn.

  Therefore, according to the cleaning device 10 as described above, when the amount of cleaning liquid 16 necessary for cleaning flows from the bottle 12 to the processing recess 32, the bottle 12 passes through the flow path in the housing 14 to the processing recess 32. Since the cleaning liquid 16 can be introduced directly and there is no need to allow the cleaning liquid 16 to flow out of the bottle, it is possible to easily perform the operation and prevent the cleaning liquid 16 from flowing out to the outside. obtain.

  Further, in the liquid processing apparatus 10, the housing 14 containing the cleaning liquid 16 and the contact lens 47 can be detached from the bottle 12 and used as a single unit, so that the contact lens 47 in the cleaning state can be easily handled. . Therefore, for example, it is easy to wash the contact lens 47 in the housing 14 or to place it in a narrow place.

  In addition, this invention is not limited to the specific structure of the washing | cleaning apparatus 10 as above-mentioned 1st embodiment, An appropriate structure is added or deleted as needed, or a specific structure is changed. It is also possible to do. For example, in addition to the inner surface of the bottle 12, a known organic or inorganic antibacterial agent is added at the time of molding, or a film is formed after molding, on the surface where the cleaning liquid 16 such as the tube 28 and the outlet 24 contacts. Antibacterial treatment can be applied. Further, it is preferable to apply the same antibacterial treatment to the gap 46 of the housing 14, the processing recess 32, the lower end surface of the lid member 52, and the like. More specifically, the antibacterial treatment includes, for example, an organic / inorganic antibacterial microbial agent such as silver, zinc, benzoic acid ester, phenolic compound, halogenated hydrocarbon, or the like in the molding polymer. In addition to coating the surface of the polymer after molding with an antibacterial microbial agent, the treatment is carried out by applying a treatment to give a photocatalytic function such as titanium oxide.

  Further, in order to improve the fluid tightness of the lid member 52 with respect to the processing recess 32 of the housing 14, the seal projection 56 of the lid member 52 is formed of a highly elastic sealing material such as silicone rubber, and the lid member 52 is formed as a lid member. 52 may be fixed to the main body.

  In addition, some of the aspects adopting different configurations as compared with the cleaning apparatus 10 of the first embodiment are specifically exemplified below, but members and parts having the same structure as the first embodiment The same reference numerals as those in the first embodiment are attached to the drawings, and detailed description thereof is omitted.

  First, the cleaning device 60 as the second embodiment shown in FIG. 5 illustrates another aspect of the seal structure of the processing recess 32 as compared with the first embodiment. In the lid member 52 of this aspect, a sealing protrusion 62 is formed on the surface overlapping the housing 14 at a portion corresponding to the upper end surface 50 of the peripheral wall of the cup member 34 of the housing 14. The seal protrusion 62 may be formed integrally with the lid member 52, or may be formed by fixing a separate member made of an appropriate rubber material to the lid member 52. In particular, the seal protrusion 62 of the present embodiment has a tapered thin-walled cross-sectional shape, is inclined and protrudes obliquely in the radial direction, and is pressed in the direction in which the cup member 34 is pressed against the upper end surface 50 of the peripheral wall. Greater elasticity has come to be demonstrated.

  Next, the cleaning device 64 as the third embodiment shown in FIGS. 6 to 7 has a structure of the inflow portion of the cleaning liquid 16 from the gap 46 to the processing recess 32 as compared with the first embodiment. Another embodiment is illustrated. In the present embodiment, the peripheral wall portion of the cup member 34 that forms the processing recess 32 is formed with a notch-shaped inflow port 66 at an appropriate number of locations on the periphery. By forming the inflow port 66, the maximum water level of the cleaning liquid 16 stored in the processing recess 32 can be set by being lowered by a predetermined amount from the upper end of the peripheral wall portion of the cup member 34. A fitting projection 68 is provided at each position corresponding to the inflow port 66 of the cup member 34 on the seal projection 56 provided on the lid member 52 and covering the processing recess 32, and the lid member 52. Is closed, the fitting projection 68 fits into the inlet 66 and covers the inlet 66, so that the fluid tightness of the processing recess 32 is secured.

  Also, as the bottle 12 employed in the present invention, a hollow structure that rises in a cylindrical shape as well as a hollow structure that rises in a cylindrical shape can be employed. For example, the fourth structure shown in FIGS. As in the cleaning device 70 according to the embodiment, a bottle 12 having a hollow structure that rises in a cylindrical shape whose cross-sectional shape and size change in the height direction may be employed. In particular, by adopting a shape in which the lower part spreads downward like the bottle 12 of the cleaning device 70, the stability when the bottle 12 is placed can be improved.

  In addition, in the cleaning device 70 of the fourth embodiment shown in FIGS. 8 to 9, the cylindrical outer peripheral surface is respectively compared with the spherical outer peripheral housing 14 and the lid member 52 shown in the first embodiment. The housing 14 and the lid member 52 are employed. As described above, the shape of the housing 14 and the lid member 52 in addition to the bottle 12 can be changed as appropriate, and has a rectangular outer peripheral surface, for example, like the cleaning device 72 of the fifth embodiment shown in FIG. As in the case of the housing 14 and the lid member 52 and the cleaning device 74 of the sixth embodiment shown in FIGS. 11 to 12, the housing 14 and the lid member 52 that exhibit a pyramidal outer peripheral surface in cooperation can be employed. The front view of the cleaning device 72 of the fifth embodiment shown in FIG. 10 is omitted because it appears in the same manner as FIG. 8 showing the cleaning device 70 of the fourth embodiment. Moreover, since the internal structures of the housing 14 and the lid member 52 in the fourth to sixth embodiments are the same as those in the first embodiment, their illustration is omitted.

  Furthermore, in the bottle 12 of the cleaning apparatus 10 of the first embodiment, the outlet portion 23 that protrudes from the upper end portion is provided, but the outlet portion is formed at an intermediate portion in the bottle height direction. It is also possible. Specifically, for example, as shown in the cleaning device 80 according to the seventh embodiment of the present invention shown in FIG. 13, from the outer peripheral surface at the intermediate portion in the height direction of the bottle 82 having a vertical cylindrical structure. A 90-degree bent tube-shaped outflow port portion 84 that extends laterally and has a distal end bent upward is formed, and a separate housing 14 can be attached to and detached from the protruding distal end portion of the outflow port portion 84. It may be attached to.

  In the seventh embodiment shown in FIG. 13, an opening 86 is formed at the upper end of the bottle 82, and the cleaning liquid 16 can be filled into the bottle 82 through the opening 86. A cap 88 that covers the opening 86 is attached by screwing or the like. For example, as shown in the eighth embodiment shown in FIG. 14, the cap 88 has an opening in addition to the outlet 23. A bottle 90 having no structure may be used. Such a bottle 90 can be manufactured by blow molding of a synthetic resin or the like, and the cleaning liquid 16 can be filled into the bottle 90 through the outlet portion 23.

  Furthermore, as shown in the ninth embodiment shown in FIG. 15, for example, a bottle 92 having a stepped portion formed in an intermediate portion in the height direction is employed, and a stepped surface 94 of the stepped portion is positioned upward. You may form the outflow port part 96 which protrudes toward. In this way, by forming the outlet portion 96 on the stepped surface 94 of the bottle 92, the housing 14 attached to the outlet portion 96 is disposed in a state of being accommodated in a notch-like portion due to the step of the bottle 92. It becomes possible. Therefore, the outward projecting amount of the housing 14 attached to the bottle 92 can be suppressed, and it becomes easy to carry the housing 14 and the outwardly projecting housing 14 is caught by other members. It can also be prevented from falling off unexpectedly.

  Further, although not shown, for example, the housing 14 can be attached to and detached from the outlet portion of the bottle 12 by screwing so that the mounting state of the housing 14 to the bottle 12 is more reliably maintained. In addition, a seal member such as an O-ring may be provided at the portion of the housing 14 where the bottle 12 is attached to the outlet 23 to further prevent liquid leakage.

  Further, when the cleaning liquid 16 is introduced into the processing recess 32 of the housing 14 by pressing the bottle 12, the cleaning liquid 16 excessively flowing out of the housing 14 flows into the processing recess 32 and overflows or enters the processing recess 32. You may form the return flow path which can be returned toward the housing 14 before flowing in.

  Furthermore, in the lid member 52 that covers the processing recess 32 of the housing 14, the processing recess 32 is sealed with respect to the external space, and the gap 46 that is a liquid supply flow path from the bottle 12 is processed. For example, a semi-seal state that leaves a slight gap between the upper end surface 50 of the outer peripheral wall of the cup member 34 is developed as necessary so that the recess 32 is in a communicating state. The processing recess 32 may be blocked from the external space and the gap 46 by shifting from the sealing state to the complete sealing state. By making it possible to set such a semi-sealed state and a completely sealed state, for example, under the semi-sealed state, the bottle 12 and the housing 14 are inverted and turned upside down, and the cleaning liquid 16 in the bottle 12 is moved by gravity to the housing 14. Then, the bottle 12 and the housing 14 are re-inverted to be in an upright state, and a predetermined amount of the cleaning liquid 16 is left in the processing recess 32 to be in a completely sealed state. Is also possible.

  In the above embodiment, the object to be processed is the contact lens 47 and the processing liquid is the contact lens cleaning liquid 16. However, the present invention is not limited to this, and a precious metal product or the like is to be processed. It is also possible to use a treatment liquid corresponding to the above.
