Further, the peripheral edge portion 24 a of the cap portion 24 of the lid portion 22 is overlaid on the upper surface 18 of the case body 12. Since the lid portion 22 is provided with a pair of cap portions 24 integrally, the pair of lens housing portions 14 is sealed with one touch. Then, the contact lens case 10 is held for a predetermined number of times, and the surface of the contact lens 1 is washed with the care agent contained therein.

  Next, the lid 22 of the contact lens case 10 is pushed up by placing a finger on the collar 34. Then, the fitting part 29 of the groove part 26 of the cover part 22 and the peripheral part 14a of the lens housing part 14 of the case body 12 are removed, and the cover part 22 is opened. When the lid portion 22 is pressed with a weak force, the lid portion is closed by the load of the spring portion 32, the step at the tip of the hook 38 abuts on the peripheral portion of the locking hole 40, and is maintained in a half-open state. As shown in FIGS. 4 and 5, an opening 42 having a certain size is formed. At this time, the tip of the lens block 36 of the lid portion 22 is located inside the lens housing portion 14 and covers most of the opening 42. Then, the contact lens case 10 is tilted in a half-open state, and the care agent with dirt is poured out from the opening 42. The contact lens 1 is locked to the lens block 36 and does not flow out. The care agent that flows out flows down along the draining protrusion 39 of the lid portion 22 and does not leak into the outer surface of the leg portion 20 of the case body 12 or the lens housing portion 14.

  Next, the inclination of the contact lens case 10 is returned to the original position, and the collar 34 of the lid portion 22 is pushed up.

And a care agent is newly put in the lens accommodating part 14, and the contact lens 1 is immersed. The lid portion 22 is pushed and closed to the case main body 12 to be sealed, and the contact lens 1 is stored. Next, when the contact lens 1 is used, the lid 34 is opened by pushing up the collar 34. The stored contact lens 1 is worn after being washed away with a care agent before use.

  After use, the contact lens case 10 is washed with water and then placed on a desk or the like with the lid 22 open as shown in FIG. By drying in this state, the inner side of the lens housing portion 14 is not blocked or brought into contact with other members.

  According to the contact lens case 10 of this embodiment, the contact lens 1 can be easily accommodated together with the care agent, and can be reliably cleaned while being accommodated without being touched by the hand. The lid part 22 can be self-supported in an open state at a predetermined angle, and operations such as taking in and out of the contact lens 1 and injection of a care agent are easy. In addition, the lid portion 22 is provided with a hook 38 that is locked half-opened and a lens block 36 that prevents the contact lens 1 from flowing out, so that only the care agent can be flowed without flowing the contact lens 1. Therefore, it is hygienic because it can be cleaned with a care agent without directly touching the contact lens 1. Moreover, since the draining protrusion 39 is provided in the cover part 22, when the care agent is thrown away, it does not leak back and is clean. Since the lid portion 22 is provided with a pair of cap portions 24 for closing the pair of lens housing portions 14, the pair of lens housing portions 14 can be simultaneously opened and closed with one touch, and the operation is simple. The pair of lens housing portions 14 can be easily opened and closed by pulling up or pressing the collar 34. The method of cleaning the contact lens 1 with the contact lens case 10 requires an opening / closing operation in the order of opening, closing, half-opening, opening, and closing the lid portion 22 and is troublesome, but is easy because the opening / closing operation is simple. Can be done.
