Description

  The present invention relates to a contact lens case.

  A contact lens user carries a contact lens case to attach and detach the contact lens on the go. In a conventional contact lens case (see, for example, Patent Document 1), a right accommodating portion that accommodates a right eye contact lens and a left accommodating portion that accommodates a left eye contact lens are separately provided. Further, an inner lid (intermediate plate 3) is provided to seal the right housing portion and the left housing portion.

However, in order to accommodate the left and right contact lenses, it is necessary to inject a storage solution into the left accommodation portion and the right accommodation portion, respectively. That is, it was necessary to inject the preservation solution twice. Further, since the mirror is attached to the outer lid, the inner lid has to be closed and opened when attaching and detaching the contact lens, which is difficult to handle and takes time. Further, in order to clean the contact lenses after use, it has been necessary to go to a washroom or a place with a sink that can receive the used cleaning liquid.

It has an annular ridge that touches it. Further, the tray portion has a receiving piece that protrudes horizontally inward at an intermediate depth position, and the receiving piece is configured to receive the mirror in the closed state. Further, the lens housing portion is divided into a left housing portion and a right housing portion with a partition, and the partition has a communication window portion for communicating the left and right housing portions.

  The contact lens case for a soft contact lens, wherein the left and right housing portions each have two guide ridges in the front-rear direction for facilitating removal of the contact lens on the bottom surface, and the bottom surface Is formed so that its front side gradually becomes shallower forward.

  Also, a contact lens case for a hard contact lens having a left holding portion for holding the left-eye contact lens in a holding shape and a right holding for holding the right-eye contact lens in a holding shape in the lens housing portion The part is pivoted so that it can lie down and stand upright.

  According to the contact lens case of the present invention, the contact lens can be attached and detached with a minimum amount of work and the contact lens can be stored in a sanitary manner. That is, everything necessary for attaching and detaching the contact lens is provided, and the contact lens can be easily put in and out.

  FIGS. 1-7 shows the use condition of the 1st Embodiment of this invention. This contact lens case is for a soft contact lens, and includes a resin case main body 1 that accommodates the contact lens C, and a resin lid 2 that is pivotally attached to the case main body 1. The case body 1 and the lid 2 can be opened and closed with one touch. The case body 1 includes a lens housing portion 3 that houses the contact lens C, and a tray portion 4 that receives the used cleaning liquid W. The lid 2 has a mirror 5.

The lens housing portion 3 is divided into a left housing portion 7 for housing the left eye contact lens C ₁ with a partition wall 6 and a right housing portion 8 for housing the right eye contact lens C ₂ . In the closed state of the contact lens case, the upper edge 6a of the partition wall 6 is in contact with the lid 2, and the left and right contact lenses C, C can be prevented from being confused. The partition wall 6 has a communication window portion 9 that allows the left and right housing portions 7 and 8 to communicate with each other. The left and right accommodating portions 7 and 8 have two guide protrusions 10 each having a substantially semicircular cross section in the front-rear direction for facilitating removal of the contact lens C on the bottom surfaces 7a and 8a. The bottom surface 7a and the bottom surface 8a are formed so that the front side gradually becomes shallower forward.

  The lens housing portion 3 has a peripheral protrusion 12 with which the lid 2 abuts in the closed state. An annular packing 13 is attached to the outside of the peripheral ridge 12. The lid 2 has an annular ridge 14 that contacts the annular packing 13 when the contact lens case is closed.

  The tray part 4 has the receiving piece 15 which protrudes horizontally inwardly at the intermediate depth position. The receiving piece 15 is configured to receive the mirror 5 in the closed state. In other words, the depth d of the upper surface 15a of the receiving piece 15 is determined by the projection of the mirror 5 from the reference surface 2a of the lid 2—the surface of the case body 1 that is in contact with the peripheral surface 1a of the tray portion 4— It is set equal to the dimension h. Further, the planar view shape of the mirror 5 in the opened state of the contact lens case is set to the same or slightly smaller shape than the planar view shape of the tray part 4 in the opened state. An absorber 16 made of sponge, tissue paper folded so as to conform to the shape of the tray 4 is accommodated below the tray 15 of the tray 4. The receiving piece 15 has a function (stopper function) for preventing the absorber 16 from being detached from the receiving tray 4.

  Reference numeral 17 denotes a cleaning liquid bottle. The case body 1 has a recess 18 for storing the cleaning liquid bottle 17. A substantially rectangular parallelepiped packing 19 is stored in the recess 18 to seal the opening 17a of the cleaning liquid bottle 17 and prevent the cleaning liquid W stored in the cleaning liquid bottle 17 from leaking. Since the packing 19 is provided, the grandchild cap of the cleaning liquid bottle 17 can be omitted, and it is not necessary to open and close the grandchild cap, and the cleaning liquid W can be used easily.

Next, a method for using the contact lens case will be described.
In order to remove (detach) and attach the attached contact lens C to the contact lens case, the contact lens C is first washed with a cleaning liquid W (rinse washed) and then accommodated in the lens accommodating portion 3. A preserving solution P is put in the lens housing 3 in advance. For soft contact lenses, the cleaning liquid W can be used as the storage liquid P.

Specifically, as shown in FIG. 4, the contact lens C is placed on the tip of the finger Y, and the cleaning liquid W stored in the cleaning liquid bottle 17 is dropped from above. At this time, it is preferable to wash while lightly rubbing with the index finger Y ₁ and the thumb Y ₂ . The receiving part 4 receives the cleaning liquid W after use (that is, after cleaning of the contact lens C). The absorber 16 absorbs the cleaning liquid W. When the absorbent body 16 is a sponge, it can be used again by squeezing the sponge after returning home. When the absorbent body 16 is tissue paper, after returning home, the used tissue paper may be discarded and replaced with new tissue paper.

  In order to attach the contact lens C accommodated in the lens accommodating portion 3, the contact lens C is slid forward along the guide protrusion 10 with the finger Y as shown in FIGS. Take it out and put it on your eyes. As described above, since the bottom surface 7a and the bottom surface 8a are formed so that the front side gradually becomes shallower forward, the contact lens C can be easily taken out and can be taken out with the belly of the finger Y. It is possible to prevent the contact lens C from being scratched by the nail N.

8 to 10 show the usage state of the second embodiment. This contact lens case is for a hard contact lens, and a U-shaped left holding portion 20 for holding the left-eye contact lens C ₁ in a holding shape and a right-eye contact lens C ₂ in the lens housing portion 3. A U-shaped right holding portion 21 that is held in a pinched shape is pivotally attached so as to be able to fall sideways and stand upright.

9 shows a state in which the left holding unit 20 is erected, and FIG. 10 shows a state in which the left holding unit 20 is laid down to the maximum extent—the state in which the rotation angle θ from the standing state in FIG. ─── is shown. The left holding portion 20 is rotatable between the standing state of FIG. 9 and the maximum sideways state of FIG. The left holding portion 20 is separated from the bottom surface 7a of the left accommodating portion 7 in the maximum sideways state. It is possible to prevent the contact lens C from being cracked regardless of the rotation angle position of the left holding portion 20.
The configuration of the right holding unit 21 is the same as the configuration of the left holding unit 20.

  The design of the present invention can be changed. For example, the partition wall 6 may include a plurality of communication window portions 9.

  As described above, according to the present invention, the case main body 1 that accommodates the contact lens C and the lid 2 that is pivotally attached to the case main body 1 are provided. The contact lens C is cleaned at an arbitrary place because it has the part 3, the cleaning liquid bottle 17 for storing the cleaning liquid W, and the receiving tray 4 for receiving the used cleaning liquid W and the lid 2 has the mirror 5. Thus, the used cleaning liquid W can be temporarily stored, and the contact lens C can be attached and detached. Moreover, since the contact lens C can be accommodated after being cleaned, it is excellent in terms of hygiene. Further, it is not necessary to carry and use a mirror or cleaning liquid W separately from the contact lens case, which is convenient.

  Further, the lens housing 3 has a peripheral ridge 12 with which the lid 2 abuts in the closed state, and an annular packing 13 is attached to the outside of the peripheral ridge 12, and the lid 2 is annular in the closed state. Since the ring-shaped protrusion 14 is in contact with the packing 13, it has excellent sealing performance, and an inner lid is unnecessary, and the trouble of opening and closing the inner lid when attaching / detaching the contact lens C can be omitted.

  In addition, the receiving tray 4 has a receiving piece 15 protruding horizontally inward at the intermediate depth position, and the receiving piece 15 is configured to receive the mirror 5 in the closed state. It is possible to prevent the mirror 5 from breaking.

  Further, the lens housing part 3 is divided into a left housing part 7 and a right housing part 8 with a partition wall 6, and the partition wall 6 has a communication window part 9 for communicating the left and right housing parts 7, 8. It is possible to prevent the lenses C and C (generally having different powers) from being stored in the opposite direction, thereby preventing confusion between the left and right contact lenses C and C. Further, if the storage solution P is injected into either the left storage unit 7 or the right storage unit 8, the storage solution P can be put into both the left storage unit 7 and the right storage unit 8.

  The contact lens case for the soft contact lens has left and right accommodating portions 7 and 8 each having two guide protrusions 10 in the front-rear direction for facilitating removal of the contact lens C on the bottom surfaces 7a and 8a. Since the bottom surfaces 7a and 8a are formed so that the front side gradually becomes shallower forward, the contact lens C can be taken out easily and reliably.

  Further, the contact lens case for a hard contact lens, the left holding portion 20 for holding the left-eye contact lens C in a holding shape, and the right-eye contact lens C are held in the lens housing portion 3 in a holding shape. Since the right holding portion 21 is pivotally mounted so as to be able to lie down and stand upright, the contact lens C can be accommodated easily and reliably while preventing the left and right contact lenses C from being confused.
