Abstract

The vessel containing zeolite therein for contact lens has germicidal property inhibiting the growth of microorganism and removing contaminants. Thus, the vessel is sterilized without boiling it or treating it with chemical agent, and has lasting germicidal property. Fine powder zeolite of white color having particle size of 200 mesh is formed as board of 1 mm thick. In this case, the shape and size of board is fitted to install in cap or bottom of the vessel. And then the board is introduced into or attached to cap or bottom of the vessel. The use of the vessel produced with such zeolite provides inhibition of growth or formation of pathogen, and good germicidal effect. Also, the content in vessel is not rotted without using germicide or antiseptic, so it is preserved for a long time. Thus, the vessel can be used conveniently.

Description

Contact Lens Container with Zeolite

The present invention relates to a contact lens container having a zeolite embedded therein.

The present invention relates to a contact lens container which solves the hassle of disinfection by inserting a plate made of zeolite with excellent sterilizing power into a case of a contact lens storage case and manufacturing a contact lens container.

The contact lens container used in the existing container for storing contact lenses takes a lot of time and money by sterilizing and disinfecting with boil or chemicals to remove or prevent microorganisms or contaminants such as molds. It has a problem that accompanies it.

In addition, the contact lens case is a container for holding the contact lens in direct contact with the eye, so the sterilization process should be made very carefully, when using the drug may cause unnecessary problems by reacting the drug with the lens.

Many attempts have been made to solve these problems, and various fungicides, surfactants, and preservatives have been developed.

However, surfactants and disinfectants can cause water pollution in severe cases, and even if a small amount of residue remains in the contact lens container after washing, it adversely affects the lens, which may cause eye damage when wearing such lenses. .

In addition, the disinfectant or surfactant is a major disadvantage that can not expect long-term sterilization effect.

Therefore, it can be found that a perishable substance such as a liquid contained in a contact lens container is modified by a microorganism such as a mold after a certain period of time.

The present inventors have completed the present invention for a long time to solve the above disadvantages.

An object of the present invention is to provide a contact lens container having a perfect sterilizing action and a nearly permanent sterilizing function by manufacturing a contact lens container containing a zeolite plate.

An object of the present invention is to provide a contact lens container having a permanent sterilization function by being sterilized without interruption or chemical treatment, so that the container itself has a sterilization function for removing contaminants and suppressing propagation of microorganisms.

Zeolite used in the present invention is a hydrous alkali metal salt of crystalline alumino and silicate. It is polar and has adsorption and ion exchange capacities. It is widely used for dehydration, purification and separation of gases and liquids, catalysts, ion exchangers and filters.

In addition, zeolites have a function of adsorbing and removing various contaminants and are known to be used in various ways as soil improvers, toothpaste additives, vinyl packaging agents, air cleaners, and deodorants for refrigerators.

However, reports of the use of zeolites in contact lens containers for sterilization purposes are not found in any prior literature.

The contact lens container according to the present invention has the following advantages.

(1) Existing contact lens containers are cleaned using a detergent that boils or contains a surfactant when sterilizing and disinfecting, but the contact lens containers of the present invention have sterilization and disinfection capabilities in the container itself. There is no need to handle this separately.

(2) Surfactants, preservatives, and disinfectants that were previously used for sterilization and disinfection may cause further chemical denaturation due to interaction with the substance if residue remains in the contact lens container after use. However, the contact lens container of the present invention has a continuous disinfecting and disinfecting effect and has no side effects.

(3) The material of zeolite is a mineral material, which is an ideal material that does not change even when boiled or heated. When used as a container for storing contact lenses, its sterilization effect is excellent under any circumstances.

Therefore, the contact lens container incorporating the zeolite plate of the present invention is a new contact lens container that completely eliminates the harmful effects of chemicals by sterilizing and disinfecting the container itself without using any disinfectant, antiseptic, or surfactant.

Hereinafter, a contact lens container using the zeolite of the present invention will be described in more detail with reference to the following examples.

Example

Zeolite in the form of fine white powder having a particle size of about 200 mesh is formed into a sheet having a thickness of about 1 mm.

At this time, the shape and size of the plate is enough to be installed on the lid of the contact lens container or the inner bottom of the contact lens container.

If necessary, the plate may be molded into a form that can be inserted or attached to the inner wall of the contact lens container.

The plate is inserted or attached to the inside of the contact lens container lid or the bottom of the contact lens container.

In the case of a plate formed into a shape that can be inserted into the inner wall of the contact lens container, the plate is inserted into the contact lens container.

As described above, the contact lens container of the present invention is completed.

Experimental Example 1: Sterilization Test

The zeolite disk prepared by the method of Example was attached to the inside of the contact lens cover, and the saline solution was placed in a non-sterilized bottle, and the lid was filled with the lens, and then the conditions were in the order of 1 day, 10 days, 30 days, and 6 months. Observed.

As a result, no other contaminants or pathogens or fungi were generated in the saline solution.

Experimental Example 2: Sterilization Test

The nutrient medium is inoculated with Staphylococcus aureus, Pseudomonas aerugosa, and E. coli, respectively, and incubated at 35 ° C for 24 hours. The medium was tested in sterilizing power by distilled water in a contact lens container manufactured by the method of Example as follows. The results are shown in the table below.

Experimental Example 3

After the following bacteria were grown in the same manner as in Experimental Example 2, the disc of Example was mounted on the inner bottom of the contact lens container, and then sterilization was tested.

The results are shown in the table below.

As described above, when the contact lens container made of zeolite was used, the formation and growth of pathogens was suppressed and the bactericidal effect was excellent. In addition, the present invention is a new contact lens container having an excellent and simple effect that cannot be seen in a conventional contact lens container because it can be stored for a long time without corrupting the contents in the contact lens container without other disinfectants or preservatives.
