The present invention provides a contact lens storage case, and more particularly, a contact lens storage case that allows for mass production at ease, and allows easy closure of the stopper and the body. It is about.

The existing case for contact lens storage has a structure that spirally processes the contact parts between the case body and the stopper so that they can be separated from each other. The manufacturing cost of the spiral lens mold is expensive and long-lasting. In use, there is a problem that the fastening force between the stopper and the main body is weakened by causing deformation of the spiral part.

Particularly, in the spiral coupling means, the stopper and the main body are continuously twisted to be coupled to each other, so that a severe torque is temporarily applied to the fastening portion between the stopper and the main body, thereby damaging the case itself. It is to provide a cause that causes the weakening force.

In addition, the stopper uses a separate thin rubber packing as a sealing means has a problem that there is a lot of risk of losing when opening and closing the stopper from the bottle.

On the other hand, a disposable soft lens (disposable lens) is a lens that is discarded after use once, the price is inexpensive, the situation is not able to use expensive glass bottles and the like. Disposable aluminum containers currently in use are not reusable once opened and cannot be inspected when sealed. Therefore, if the contents are unpacked after opening, the disposable container is more wasteful because the lens cannot be re-packed after disinfection.

The present invention has been devised to solve the above-mentioned shortcomings, and provides an advantage of enabling mass production of the lens storage case at a low price by improving the coupling means of the case stopper and the main body.

In addition, the combination of the case plug and the main body provides an advantage that can be easily and firmly coupled without applying excessive force.

In addition, the torque is not generated at the time of coupling the case plug and the main body, thereby providing an advantage that the coupling portion of the case itself is not easily worn or deformed even during long-term use.

In addition, since the torque does not occur at the time of coupling the case plug and the main body, it provides an advantage that the coupling portion of the case itself is not easily worn or deformed even during long-term use.

In addition, since the sealing means is integrally molded to the case stopper, the sealing means may be detached from the stopper during use, and thus there is no risk of losing the sealing means. In addition, it is repeatedly reused when used as a disposable soft lens storage case. This is possible and offers the advantage of allowing the contents of the container to be externally identified.

That is, in order to achieve the above objects, the present invention provides a contact lens storage case of a known structure in which a stopper and a main body for storing a contact lens are screwed to each other so that the upper part is opened while the bottom part is a bottom wall part. Closed, the outer circumference of the lower body is " And a case stopper having four recessed grooves, and a deep space portion having only an upper portion formed therein, and a case body having four fixing protrusions protruding toward the inside at the upper inner edge portion of the space. When the stopper and the main body are combined so that the fixing protrusions are inserted into each fixing recess, the stopper is integrally formed on the bottom wall of the stepped end of the stopper. The annular stone piece having an elastic force of "" is configured to seal the periphery of the opening of the main body space portion, and the bottom wall portion of the lower body of the stopper is located deep into the space portion to serve as the inner plug.

The above objects and other features and advantages will become more apparent on the basis of the embodiments according to the accompanying drawings. The present invention is by no means limited to the following examples.

1 is an exploded perspective view of the case for storing the contact lens 1 according to the present invention, and shows a state in which the case stopper 2 and the case body 4 are separated from each other.

The case stopper 2 has an upper portion open to the outside, while the bottom portion is closed by the bottom wall portion 6, and the middle portion forms a cylinder provided with a step 8.

The case body 4 coupled to the stopper 2 is formed therein with a space 10 having only an upper portion for inserting a portion of the body of the stopper 2 so as to be accommodated therein.

On the outer circumferential surface of the lower body of the case plug 2, the vertical opening 12a, which opens only the lower portion in communication with the outside when viewed from the front, becomes perpendicular to the vertical opening 12a continuously and gradually narrows in width. An inclined path 12a which is inclined so that its end is closed. Of the fixing recesses 12 are installed in four places, and the stopper 2 is inserted into the case body 4 into the fixing recess 12 installed in the inner circumferential surface of the closure 2, the case body 4 The fixing protrusions 14 protruding with the same number as the fixing recess grooves 12 are inserted and fixed to the inner edge of the opening, and at this time, the stopper 2 is integrated with the stopper 2 on the bottom wall 16 of the stepped portion 8. From the cross-section formed by Resilient annular stone piece 18 is in contact with the opening 10 of the space portion 10 of the case body 4 to close the case body 4 in a watertight manner.

In the drawings according to the embodiment, the stopper 2 and the case body 4 and the cylindrical body is shown as an example, but may be modified in other forms such as a quadrilateral. In addition, these materials may be polypropylene or polycarbonate which is preferable in terms of suitable use, and the case plug 2 or the main body 4 may be manufactured to be transparent to the inside.

In the drawings, reference numeral 24 denotes a reinforcement protrusion formed on the surface of the stopper, 26 denotes an inclined periphery formed on the bottom wall of the stopper, 28 denotes an inclined periphery formed so that the inclined periphery is in contact with each other; Reference numeral 30 denotes the contact lens L receiving portions, respectively.

The effect of the present invention with the configuration as described above is as follows. As shown in FIG. 1, in a state in which the case plug 2 and the case main body 4 are separated, the housing portion provided with the contact lens L at the bottom of the cylindrical space 10 in the case main body 4. In the case of safe storage after putting it in the (30) side, the inner part of the opening of the space part 10 is made when a part of the bottom body of the stopper 2 is first inserted into the opening side of the space part 10 of the case body 4. The four fixing protrusions 14 at are positioned to be guided deeply into the vertical openings 12a of the corresponding fixing recesses 12 so as to be positioned at the point "P" as shown in FIG. The annular piece 18 is in contact with the case periphery of the opening of the case body 4. In such a state, if the case stopper 2 is held by hand and slightly rotated in the direction of the arrow A as shown in FIG. As shown in FIG. 2, the annular stone piece 18 having an outer portion closes more tightly to the opening periphery of the main body 4, and a portion of the lower body of the stopper 2 is located on the main body 4. Deeply inserted into the space portion 10, the bottom wall portion 6 serves as an inner plug to close the inside of the space portion 10, and the fixing protrusions 14 located at the "P" point are inclined. Along the 12b, it moves toward the corner of the ramp 12b, which is narrower and narrower, and is pinched at the closed corner of the narrow ramp 12b as soon as it reaches the point "P".
