Abstract

Provided is an ocular device case with a new structure that can solve unexpected problems in the related art, for example, adverse effects on user's eyes by splashes of treatment liquid upon pouring the treatment liquid into the device case from a separate refill container. In a device case 10 including: a case body 18 accommodating treatment liquid 12 with ocular devices such as a contact lens 16 ; and a lid 20 , a container receiving portion 48 is provided such that a spout 106 of a refill container 100 is brought into contact with the refill receiving portion 48 so as to allow the treatment liquid 12 to flow into the device case 10.

Claims (54)

1 . An ocular device case for use by injecting a treatment liquid from a separate refill container, the ocular device case comprising:

a case body having a storage area for the treatment liquid and configured to store an ocular device;

a lid attached to an opening of the storage area in the case body;

a container receiving portion configured to contact a spout of the refill container to allow the treatment liquid to be injected into the storage area; and

an insertion port configured to have the spout of the refill container inserted into the insertion port,

wherein the container receiving portion is inward of the insertion port such that the container receiving portion projects from the insertion port into an inside of the storage area,

the ocular device case is configured to removably insert an ocular device, and

the container receiving portion is arranged to contact the spout of the refill container from above and pour the treatment liquid from the separate refill container into the storage area.

2 . The ocular device case according to claim 1 , further comprising a support portion for supporting the ocular device in the storage area.

3 . The ocular device case according to claim 1 , wherein the container receiving portion is arranged to contact the spout of the refill container pointed downward from above in an upright state of the case body while the lid is attached.

4 . The ocular device case according to claim 1 , wherein the container receiving portion is configured such that an insertion depth of the spout of the refill container with respect to the insertion port is configured to be limited by a contact of a tip of the spout of the refill container with the container receiving portion.

5 . The ocular device case according to claim 1 , wherein the container receiving portion and the storage area are configured such that a contact position of a tip of the spout of the refill container configured to be positioned in the container receiving portion is above a prescript position of a liquid surface level of the treatment liquid in the storage area.

6 . The ocular device case according to claim 1 , further comprising the ocular device supported in the storage area by a support portion, and an agent acting on the treatment liquid in the storage area of the case body, wherein the lid is attached.

7 . The ocular device case according to claim 1 , wherein the container receiving portion comprises a guide flow path configured to guide the treatment liquid injected from the spout downward from a contact position of a tip of the spout of the refill container.

8 . The ocular device case according to claim 1 , wherein a surface of the container receiving portion is coated with a water-repellent or hydrophobic surface coat.

9 . The ocular device case according to claim 1 , further comprising the treatment liquid, wherein the treatment liquid is for disinfecting or cleaning the ocular device and comprises any one of the following:

a peroxide selected from hydrogen peroxide, perboric acid, peracetic acid, performic acid, and salts thereof;

an oxide of chlorine selected from chlorine dioxide, chlorite, hypochlorite, and salts thereof; and

Povidone Iodine.

10 . The ocular device case according to claim 1 , further comprising the ocular device, wherein the ocular device is at least one of

a contact lens for vision correction of at least one of myopia, hyperopia, and presbyopia;

a cosmetic contact lens for at least one of iris coloring and limbal dilation;

a myopia suppression contact lens,

an orthokeratology contact lens;

a contact lens for conical corneal;

a functional contact lens equipped with at least one of sensors, communication functions, and imaging functions;

a non-crystal intraocular lens; and

a crystal intraocular lens.

11 . A combination of the ocular device case according to claim 1 and the refill container, the refill container comprising:

the treatment liquid,

the spout through which the treatment liquid flows out; and

a shutoff valve body having a protrusion protruding outward from a tip of the spout, wherein

the shutoff valve body is in the spout such that the shutoff valve body is urged from an inside toward an outside of the spout with the protrusion protruding outward to block the spout, and

with the protrusion at the spout being brought into contact with the container receiving portion of the ocular device case and pushed inward, the spout opens to allow the treatment liquid to flow out from the spout.

12 . An ocular device case for use by injecting a treatment liquid from a separate refill container, the ocular device case comprising:

a case body having a storage area for the treatment liquid and configured to store an ocular device removed by a user;

a lid attached to an opening of the storage area in the case body, and

a support portion for supporting the ocular device in the storage area, the support portion being attached to the lid, wherein

an entirety of the lid is configured to be removably attachable to the case body, and

the ocular device case is configured to allow pouring the treatment liquid into the storage area in a state where the lid is mated to the case body.

13 . An ocular device case for use by injecting a treatment liquid from a separate refill container, the ocular device case comprising:

a case body having a storage area for the treatment liquid and configured to store an ocular device;

a lid attached to an opening of the storage area in the case body;

a container receiving portion configured to contact a spout of the refill container to allow the treatment liquid to be injected into the storage area; and

an insertion port configured to have the spout of the refill container inserted into the insertion port,

a holder cap in direct contact with the container receiving portion and configured to be removable from the case body and further configured to submerge the ocular device in the storage area, wherein

the container receiving portion is inward of the insertion port such that the container receiving portion projects from the insertion port into an inside of the storage area, and

the ocular device case is configured to removably insert an ocular device.

14 . An ocular device case for use by injecting a treatment liquid from a separate refill container, the ocular device case comprising:

a case body having a storage area for the treatment liquid and configured to store an ocular device removed by a user;

a lid attached to an opening of the storage area in the case body,

a holder cap within the case body and configured to be removable from the case body and further configured to submerge the ocular device in the storage area, wherein

an entirety of the lid is configured to be removably attachable to the case body, and

the ocular device case is configured to allow pouring the treatment liquid into the storage area in a state where the lid is mated to the case body.
