Description

Application for application under Article 30, Paragraph 2 of the Patent Act Refer to the certificate submitted on November 27, 2nd year of Reiwa for application of the exception to the loss of novelty of the invention.

The present invention relates to a case for storing contact lenses.

Conventionally, various contact lenses have been widely used according to the wearer's purpose, such as the purpose of correcting eyesight and the purpose of fashion to change the appearance color of the iris portion.

Contact lenses are roughly classified into hard contact lenses and soft contact lenses according to the difference in their materials. In particular, hard contact lenses are used repeatedly for a long period of time, so there are cases where they are stored in a special cleaning solution. You will need it.
In addition, some soft contact lenses are used repeatedly over a period of two weeks, one month, or the like, and these also require a special cleaning solution or a case of storage.

As a case for storing contact lenses that are used repeatedly as described above, for example, in Patent Document 1, while storing contact lenses, the mounting surface can be cleaned with a simple structure and without damaging the contact lenses. A case for contact lenses is described so that it can be easily performed.

This contact lens case has a structure in which the bottom portion of the lens accommodating portion is formed in a convex shape that rises in the cap direction, and the surface of the bottom portion is formed with irregularities.
As a result, when the mounting surface of the contact lens is set on the bottom of the lens housing, the mounting surface and the unevenness come into contact with each other, and the contact lens moves in the front-back direction or the left-right direction while the surface side of the contact lens is lightly pressed with a finger. Alternatively, by rotating it, the mounting surface can be cleaned.

The number of the detachable means components 13a is not limited to two, and three or more may be provided in order to improve the stability of each accommodating portion 11 inside the case.

Each detachable means component 13a is composed of a first component 13a1 extending upward and a second component 13a2 extending laterally from the upper end of the first component 13a1 to form an inverted L shape. It is made into a shape.

Here, when mounting each accommodating portion 11 on each base portion 14, the user pushes each accommodating portion 11 toward the upper surface of each base portion 14.
As a result, each of the first constituent portions 13a1 is pressed outward by each of the mounting portions 11b, and due to the elastic force thereof, the accommodating portions 11 are sandwiched while being slightly curved outward.
The height of each of the first constituent portions 13a1 is substantially the same as the height of each of the mounting portions 11b.

Then, by pushing each accommodating portion 11 further downward, the user mounts each mounting portion 11b on each base portion 14 while each mounting portion 11b is sandwiched by each first component portion 13a1. To.
Further, at this time, each second component 13a2 is in contact with the upper surface of each mounting portion 11b, and each accommodating portion 11 is in the state shown in FIG. 3 and is stably mounted on each base portion 14. To.
When removing each accommodating portion 11 from each accommodating portion 11 to each base portion 14, the user only lifts each accommodating portion 11 upward, and each detachable means component 13a is deformed by the elastic force thereof. It can be easily removed.

Each base portion 14 is configured to have a substantially cylindrical shape, and each irradiation portion 3 is arranged inside the base portion 14.
Further, each base portion 14 is configured to have a height such that each irradiation portion 3 does not protrude upward from the upper surface of each base portion 14.

FIG. 5 (a) is a cross-sectional view taken along the line PP'in FIG. Part 3 is not shown in the cross-sectional view. ..
FIG. 5B is a cross-sectional view taken along the line QQ'in FIG. 2A, and the battery B and the like stored in the storage space w are not shown in the cross-sectional view.

As shown in FIG. 5, each accommodating portion 11 is attached to each attachment / detachment means 13, and the case main body 1 is closed by the lid portion 2, so that each window portion 21 is arranged directly above each irradiation portion 3. To.
Further, each contact lens L is irradiated with ultraviolet rays by the irradiation unit 3 via the mounting portion 11b.

Further, as shown in FIG. 5A, a magnifying lens 21a is fitted in each window portion 21.
As a result, the user can visually recognize each contact lens L in an enlarged state through each window portion 21 and cap portion 12.
In the present embodiment, the magnifying lens 21a is a plano-convex lens, but the lens is not limited to this, and may be a biconvex lens, a convex meniscus lens, or the like.

Further, as shown in FIG. 5B, the battery B and the control unit C are stored in the storage space w formed below the partition base portion 15.

The battery B can be repeatedly charged by connecting to a predetermined charging cable via the charging hole 1d described above.
As the standard of the charging terminal, various standards such as a USB terminal and a Lightning terminal can be adopted. Further, by using a known wireless charger, a configuration capable of non-contact charging (wireless charging) by electromagnetic induction or the like may be used.
In addition, a space for replaceably accommodating dry batteries, button batteries, etc. may be provided in the storage space w, and the control unit C may be driven by these batteries. This configuration and the rechargeable battery B may be used. It may be used in combination with the existing configuration.

The control unit C is electrically connected to the battery B, each irradiation unit 3, and the timer unit 4.
As a result, the control unit C switches the irradiation state of each irradiation unit 3 to ON / OFF based on the operation of the irradiation button 1c, and the display mode of the display monitor 4a based on the operation of the start button 4b and the reset button 4c. Controls the execution of the countdown and the transition to the setting mode).

Further, as shown in FIG. 5B, the locking means h2 has a locking means main body h21 projecting upward from the recess r and an unlocking means projecting laterally from the locking means main body h21. It is composed of a part h22.

The locking means main body h21 is a thin plate-like body, and a locking projection m slightly protruding toward the side is provided above the thin plate-shaped body.
The locking projection m is an open end of the lid portion 2 and is locked in a locking groove n provided directly above the recess r.

With this configuration, the rotation operation of the lid portion 2 about the hinge portion h1 is controlled, and the closed state of the case body 1 is stably maintained.
Further, by pressing the locking release portion h22, the user bends the locking means main body h21, eliminates the locked state of the locking projection m and the locking groove n, and easily opens the case main body 1. It can be in a state (state shown in FIG. 3).

According to the present embodiment, the contact lens case X has the following effects.

That is, according to the present embodiment, since the irradiation unit 3 is a black light that emits ultraviolet rays toward the accommodation space S, it is possible to visualize stains adhering to the contact lens L that cannot be normally seen with the naked eye.
