Abstract

PURPOSE:To simplify the structure of the title contact lens container so as to make it handy by constituting the container of a container main body made of a synthetic resin provided with a pair of lens housing section filled up with a contact lens preservative liquid and aluminum foil sealing the opening section of the main body, with the peripheral section of the aluminum foil being thermally adhered to the main body. CONSTITUTION:The container main body 1 is made of a synthetic resin and provided with a lens housing section 2 for left eye and another lens housing section 3 for right eye. Each lens housing section 2 and 3 is filled up with a lens preservative liquid 4. In addition, the top of the container main body 1 is opened for putting in and taking out lenses from the sections 2 and 3 and the opened section 5 is sealed with the aluminum foil 6. The marginal section of the foil 6 on the rear side is coated with a synthetic resin layer and the foil 6 is thermally adhered to the container main body 1 by the marginal section. Thus this contact lens preservative container is sealed. Therefore, this contact lens preservative container becomes simpler in structure and easier in handling, because lenses 7 and 8 can be put in and taken out from the lens housing section 2 and 3 by simply lifting up one edge of the aluminum foil 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a simple storage container for contact lenses, and particularly to a simple storage container for contact lenses that is inexpensive, easy to handle, and disposable.

[Prior Art] In recent years, contact lenses have come into widespread use, especially among young women, in order to improve the performance of contact lenses and from the viewpoint of beauty. In addition, soft contact lenses that do not particularly damage the eyeballs have been developed and are now being used.

However, soft contact lenses deteriorate due to dryness, so they must always contain moisture.
When removed, 1. For example, when going to bed, it is necessary to soak it in water. That's why, usually.

A commercially available 0.9% saline solution was placed in a predetermined storage case, and the soft contact lens was stored immersed therein.

In addition, when the surface of hard contact lenses becomes dry, ocular secretions and airborne debris can become stuck and difficult to remove, and the lenses become difficult to get wet with tears, causing them to not fit snugly around the eyes. Furthermore, bacteria and fungi can easily breed, which can lead to eye infections when wearing lenses. To prevent this, even in the case of hard contact lenses, when they are removed, a storage solution containing a disinfectant such as benzalkonium chloride is stored in a storage case that has been washed with water beforehand, and the hard contact lenses are placed inside the case. Contact lenses were stored in a soaked state.

However, with such a storage method, when staying overnight for a trip or the like, it is necessary to carry a storage solution container of approximately 500 m1 (Loom 1 in the case of hard lenses) along with the storage case. Such storage solution containers are heavy, bulky, and inconvenient to handle. Furthermore, the lid of the storage case had to be opened and closed many times in order to inject the storage solution, which was unsanitary. Furthermore, since the same storage case is used repeatedly, there is a high possibility that a user with poor eyesight may lose the storage case. In addition, in such a storage case, the storage solution must be discarded and the storage case must be washed after each use, and these operations take 10 to 30 minutes.

Furthermore, such storage cases must be made of high-strength and highly durable materials to withstand repeated use, and are very expensive.

[Problems to be Solved by the Invention] The present invention has been made under these circumstances, and has a simple structure, easy handling, low cost,
The purpose is to provide a simple storage container for disposable contact lenses.

[Means for Solving the Problems] A simple contact lens storage container of the present invention has a pair of lens accommodating portions for accommodating a contact lens storage solution, and includes a container body made of a synthetic side that opens upward, and a peripheral portion that is A sealing film body is heat-sealed to the opening of the container body.

The sealing film body can be made of aluminum foil coated with a synthetic resin layer on the entire back surface or the peripheral edge of the back surface, that is, the portion corresponding to the opening of the container body.

In this case, the sealing film body can be heat-sealed to the opening of the container body via the synthetic resin layer.

Furthermore, a protrusion may be formed around the entrance of the pair of lens accommodating parts of the container body. Such protrusions are
After peeling off the sealing film and storing the lens in the lens accommodating part, it has the effect of preventing the lid from coming off when a separately prepared lid is inserted into the lens accommodating part to prevent leakage of storage solution. .

There must be two or more protrusions to prevent the lid from coming off. Alternatively, it may be a continuous protrusion over the entire circumference.

The contact lens simple storage container of the present invention is applicable to both soft contact lenses and hard contact lenses.

[Example] Hereinafter, one embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a top view of a simple contact lens storage container according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof taken along line A-A. In FIGS. 1 and 2, a container body 1 is made of synthetic resin, such as polyethylene, polypropylene, etc., and includes a left eye lens accommodating section 2 and a right eye lens accommodating section 3. Each of the accommodating parts 2 and 3 is filled with a preservation liquid 4. The storage solution is usually a physiological saline solution, ie 0.9% saline, for soft contact lenses, and a solution containing a disinfectant such as benzalkonium chloride for hard contact lenses. The amount of storage solution is usually 5
ml.

The container body 1 is open upward for housing and taking out lenses, and the opening 5 is provided with an aluminum foil 6.
sealed by. The peripheral edge of the back surface of the aluminum fI 36 is coated with a synthetic resin layer, for example polyethylene, and the aluminum foil 6 is heat-sealed to the opening of the container body 1 through this synthetic resin layer, thereby sealing the storage container. be done.

A storage container containing a storage solution is manufactured, sold, and used in a sterilized state. In use, after peeling off the aluminum foil 6 from the container body 1, the left eye lens 7 is stored in the left eye lens storage section 2, and the right eye lens 8 is stored in the right eye lens storage section 3, respectively. After housing the lens 7.8, the lens accommodating parts 2, 3 are sealed by fitting a lid 9 with a diameter slightly larger than the diameter of the entrance of the accommodating part 2.3, as shown in FIG. The lid body 9 is attached to the lens housing section 2
．． Due to the presence of a plurality of protrusions 10 provided at the entrance part of 3, it will not come off. Although it is not possible to obtain a complete seal with this lid body 9, since the storage of contact lenses is limited to bedtime, the storage container containing the lenses is only left standing, and therefore the storage solution does not leave the container. It won't leak.

In the above, an example has been described in which the storage container after housing lenses is sealed using a separately prepared lid, but the present invention is not limited to this, and the sealing film body is not completely peeled off from the container body, and the storage container is not completely peeled off from the container body. It may be peeled off to the extent possible and then stored with the sealed film body returned to its original state after the lens is accommodated. In this method, the storage solution is not sealed, but
- It is possible to store it overnight.

[Effects of the Invention] As explained above, the simple contact lens storage container of the present invention has an extremely simple structure, and the lens can be stored in the lens accommodating portion by simply peeling off the sealing film body from the container body. It is very easy to handle. In addition, since it is sufficient to be used once or several times as a disposable item, inexpensive materials can be used and the price is low. Furthermore, since it is disposable, it is extremely hygienic.
