Contact lens case {CONTACT LENS CASE}

The present invention relates to a contact lens case, and more particularly, to store and store a soft contact lens and a hard contact lens in one case, thereby improving the convenience of the user while providing ease of storage and portability. The present invention relates to the provision of a contact lens case.

In general, a contact lens refers to a small lens manufactured to attach to the outer surface of the eye cornea, such as glasses, and such a contact lens is mainly composed of a hard contact lens and a soft contact lens.

The hard contact lens is a lens that has been used a lot because of the ability to correct astigmatism as well as myopia, and currently used hard contact lens is made of a glass material.

Such hard contact lenses have the advantage of easy circulation of tears and high oxygen permeability, and excellent oxygen permeability. Soft contact lenses are composed of hydroxyethyl methacrylate. There is not a lot of friction between the comfortable to wear.

In order to store the soft and hard contact lenses as described above, immersing the contact lenses in a case in which a preservative containing a protein remover is stored, removes the protein from the lens and prevents the growth of bacteria in the contact lenses. .

7 is a configuration diagram showing a soft contact lens case to which the prior art is applied, and FIG. 8 is a configuration diagram showing a hard contact lens case to which the prior art is applied.

The soft contact lens case 10 includes a body 13 having different left eye lenses and right eye lens storage grooves 11 and 12 so as to store left and right eye lenses (not shown) having a frequency according to visual acuity, and And a lid 14 for opening and closing the left eye lens and right eye lens storage grooves 11 and 12.

The hard contact lens case 20 includes a body 24 in which the left eye lens and the right eye lens storage grooves 22 and 23 are divided into two by the central partition wall 21, and the left eye lens and right eye lens housing grooves 22, It is configured to include a lid 26 formed to protrude the connecting pin 25 to open and close the 23 and at the same time to mount the hard lens (not shown).

In the contact lens case to which the prior art is applied, the soft and hard contact lens cases simply store the lens, so that the auxiliary tools such as the tweezers and the mirror and the lens adsorption rod can be used to easily wear the lens. It is stored in a box with a case.

In the case of a soft lens, the case shown in FIG. 7 is used to store it in a storage box. In the case of a hard lens, the case shown in FIG. 8 is used to store it in a storage box. In the case of a user who has to have two cases and a storage box is accompanied by a hassle.

Of course, when storing two cases in the home in each storage box does not cause a great difficulty or problems, but if you leave the house for a long or short period of time, such as going out or traveling, soft and hard with a lot of luggage necessary for travel It is necessary to take a storage box for each case where contact lenses are stored, and it is cumbersome to manage them separately in a travel destination.

Especially in the case of hard contact lenses, the lenses themselves are expensive, but the case for storing hard contact lenses is also more expensive than soft contact lenses. Therefore, if two types of cases and storage boxes are to be provided, it is economically expensive for users. It causes weighting.

In addition, there is a lot of trouble because the case in which the soft or hard contact lenses are stored must be separated and managed according to the selection of the lens. In the case of soft contact lenses, the lenses are simply stored in the storage grooves. In the case of hard contact lenses, it is not easy to mount a small diameter lens on the connecting pin which is integrally formed on the lid. Even in the state in which the right eye lens housing is accommodated, the phenomenon in which the lens leaves the cradle due to vibration or shock is frequently occurring.

In the process of storing and storing the lens as described above, if a phenomenon such as detachment or dropping of the lens occurs, the surface of the lens may be minutely damaged. There are many problems, such as causing damage.

Accordingly, the present invention has been invented to solve the above problems, a case body, a lens storage space formed to accommodate soft and hard contact lenses on the upper side of the case body, the lens is coupled and separated from the case body A cover for opening and closing a storage space, a lens housing part coupled to the cover to accommodate soft and hard contact lenses, and a lens in a reverse direction when the cover is coupled and a lens in a forward direction when the cover is opened; A tool storing groove formed at a bottom thereof to receive an auxiliary tool comprising a suction rod for handling a hard contact lens and a flow preventing device for preventing a flow of the stored hard contact lens; It consists of a lower cover that is disassembled and combined with each other. The objectives that can increase the user comfort of the contact lenses can be accommodated by allowing possible.

The present invention allows the soft contact lens and the hard contact lens to be stored at the same time in one case, while the case can be stored together with the storage box in which the adsorption rod for handling the hard contact lens is housed. Soft and hard contact lenses can be handled outside the home, providing convenience for storing and using contact lenses, and reducing the user's cost by providing only one case for storing soft and hard contact lenses.

Looking at the state of use of the contact lens case 100 to which the technique of the present invention is applied as described above are as follows.

The hard contact lens 103 can be easily inserted into the suction bar fitting groove 145 and the prevention hole groove 147 formed in the suction rod storage hole 146 and the prevention hole storage hole 148 provided on the inner surface of the lower cover 115. When the hard contact lens 103 is accommodated in the adsorption rod 111 and the lens storage unit 110 for handling, the flow preventing mechanism 112 for preventing the hard contact lens 103 from moving out of position The lower cover 115 is coupled to the tool storage groove 114 formed on the bottom surface of the gas body 101 in a state of fitting the auxiliary tool 113 composed of a).

After coupling the coupling protrusion 142 formed on the lower cover 115 to the coupling groove 141 formed in the tool storage groove 114, an intermittent piece 143 having elasticity is integrated into the tool storage groove 114. It is to be pushed into the intermittent jaw 144 is formed to be caught, if you want to break off, press the intermittent piece 143 to leave the intermittent jaw 144 and then the lower cover 115 tool storage groove 114 ).

Then, after filling the preservative in the lens storage space 105 formed on the upper side of the case body 101, the soft and hard contact lenses 102 and 103 necessary for the lens storage unit 110 coupled to the inner surface of the cover 106 are filled. By storing and coupling the cover 106 with the case body 101, the contact lens can be stored and carried.

The coupling of the cover 106 and the lens housing 110 includes a locking finger 136 formed at both ends of the lower end of the coupling bar 135 protruding from the inner center of the cover 106. The coupling bar 135 by the coupling protrusion 138 and the coupling groove 139 to be coupled to the finger jaw 137 is formed in the 118, the coupling bar 135 and the bridge 118 to be engaged with each other. ) And the bridge 118 is prevented from flowing while maintaining the position.

In such a state that the lens housing 110 is coupled to the cover 106, the cover 106 is separated from the case body 101 so that the top surface of the cover 106 is located at the bottom and the coupling bar 135 is disposed. The lens housing 110 combined with is naturally positioned on the top surface to maintain a normal state, thereby facilitating handling of the lens.

In addition, when the cover 106 is combined with the case body 101, the lens housing 110 coupled with the coupling bar 135 is positioned in the lens storage space 105 in a state in which the cover 106 is located in the reverse direction. The soft and hard contact lenses 102 and 103 may be preserved by the preservation liquid filled in the lens storage space 105 through the distribution hole 116 formed in the payment part 110.

The process of accommodating and detaching the soft and hard contact lenses 102 and 103 in the lens housing 110 coupled to the cover 106 will be described in detail as follows.

First, when the hard contact lens 103 is to be stored, the lens cover 120 coupled with the lens body 117 provided as a pair is opened, and then the hard lens formed in the center of the lens body 117. The hard contact lens 103 worn on the seating surface 122 may be detached from the hard lens seating surface 122, and the edge of the lens body 117 may be stored even when the soft contact lens 102 is to be stored. The soft contact lens 102 may be seated on the soft lens seating surface 126.

In this process, the edges 121 and 125 of the soft and hard contact lenses 102 and 103 are seated within a width B range of the soft and hard lens seating surfaces 126 and 122, and in the case of the soft contact lenses 102, the hard and soft lenses The recessed spherical portion 128 of the soft lens 102 is supported by the soft lens support 130 formed on the outer surface of the boundary protrusion 127 projecting between the seating surfaces 122 and 126.

In the case of the hard contact lens 103, the spherical portion 124 recessed in the bottom of the hard contact lens 103 by the hard lens support 123 protruding spherically between the hard lens seating surfaces 122 is formed. It is supported, and the lens cover 120 opened in such a state is to be closed.

In particular, when the hard contact lens 103 is stored, there is a lot of space between the outer surface of the hard contact lens 103 and the lens cover 120 so that when the cover 106 is combined with the case body 101, the direction is reversed from the forward direction. There is a concern that the hard contact lens 103 may be out of position due to vibration and shock generated during the process of changing to or moving the case 100, and the hard contact lens using the flow preventing device 112 may be used. What is necessary is just to be able to keep 103 always in place.

Looking at this, by coupling the flow preventing mechanism 112 to the fixing hole 132 formed in the center of the spherical dome 131 constituting the lens cover 120, the hard contact lens constituting the flow preventing mechanism 112 The separation prevention cup 132 having the same spherical surface as the 103 is in close proximity to the outer surface of the hard contact lens 103, and the shaft portion 133 integrally formed with the separation prevention cup 132 is fixed to the fixing hole 132. To be coupled, the locking step 134 formed in the shaft portion 133 is to be locked to the fixing hole 132.

Then, by preventing the flow stopper 112 from being separated or approaching the hard contact lens 103 more than necessary, even if the lens housing 110 is changed in the forward and reverse directions or vibration or shock occurs, the hard contact lens ( 103 is positioned between the hard lens seating surface 122 and the separation prevention cup 132 of the flow prevention hole 112 to maintain the position.

Of course, the flow preventing device 112 is made of a silicon material that does not damage the surface even if it is in contact with the hard contact lens 103, and made of a material of the lens housing 110 for accommodating the soft and hard contact lenses (102, 103) It will be appreciated that the coating may be performed on a material which does not damage the surface of the lens or on such material.

In the present invention, when the cover 106 combined with the lens housing 110 is combined with the case body 101, the lens is accommodated in a reverse state, but when the cover 106 is separated from the case body 101, the lens is separated. Since the accommodating part 110 is in a forward state, the lens cover 120 may be opened to facilitate the storing or wearing of the lens.

In addition, the present invention can accommodate the soft and hard contact lenses by using a single case, there is no inconvenience and hassle to have a case and a storage box according to the shape of the lens, respectively, in the case of a soft contact lens lens It is an invention that has various effects, such as being able to be opened and handled directly by a user's hand, so that a tool such as tweezers can be omitted while increasing the convenience of the user and reducing the cost burden.
