（産業上の利用分野）
本発明は容器自体に抗菌性を付与することにより角膜障
害を防止した抗菌性を有するコンタクトレンズ溶液用容
器に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a container for a contact lens solution having antibacterial properties that prevents corneal damage by imparting antibacterial properties to the container itself.
（従来の技術）

い潜在的な患者も多いと言われている。(Prior art) Conventionally, solutions such as contact lens storage solutions and cleaning solutions have been commercially available in containers made of synthetic resin, and in particular, after the soft lens storage solution is used up, the user dissolves the granules in purified water to store it. It is designed to create a liquid. These containers for contact lens solution are sold in a completely sterilized state, but if the user does not handle them properly after opening the container or if the container is poorly stored, bacteria that have entered from the outside can grow inside the container.
There is a risk of causing corneal damage to contact lens users, and many case reports of bacterial corneal damage have been published. Furthermore, it is said that there are many latent patients who do not have any symptoms even if they have corneal damage.
そこでコンタクトレンズに付着するタンパク賞や雑菌等

る。Therefore, contact lenses are washed to remove proteins and germs that adhere to them, and they are washed with a cleaning solution and stored in a storage solution to prevent the proliferation of bacteria, or they are regularly boiled to sterilize bacteria that adhere to soft contact lenses. Although instructions are given on how to disinfect, the reality is that all of these methods are cumbersome and are not fully implemented. Furthermore, it is desirable to sterilize the contact lens solution container itself by boiling, but this container is made of soft synthetic resin so that the solution can be squeezed out little by little without washing away the contact lenses. Therefore, sterilization by boiling is impossible due to heat resistance.
二のように、コンタクトレンズの使用者は常に細菌性角
膜傷害を起こす危険にさらされているのである。Second, contact lens users are always at risk of bacterial corneal injury.

ある。(Problems to be Solved by the Invention) The present invention solves these conventional problems and prevents the proliferation of microorganisms such as bacteria by imparting antibacterial properties to the contact lens solution container itself. This was completed in order to provide a contact lens solution container that prevents bacteria from adhering to contact lenses and allows contact lenses to be worn at all times in a clean manner.
（課題を解決するための手段）
上記の課題を解決するためになされた本発明は、溶液中

溶液用容器を要旨とするものである。(Means for Solving the Problems) The present invention, which has been made to solve the above problems, is characterized in that it is made of a resin containing soluble glass powder that can elute an appropriate amount of silver ions into a solution. The gist is a container for contact lens solution.

粒度、が６０μｍ以上であると、合成樹脂に練り込むと
きに目詰まり等の工程トラブルを起こす可能性があり、
製品表面の滑らかさを損なうおそれがある。The soluble glass used in this invention has a glass composition that has a controlled dissolution rate in saline, which is the main component of contact lens solutions, and contains 0.0% by weight of silver ions, which have an excellent bactericidal effect. It is preferable that the content be 4 to 1.6% (in terms of Ag to) and that the particle size be pulverized to a particle size of 5 to 60 μm. If the content of silver ions in the glass is 0.4% or less, it is necessary to add a large amount of soluble glass to the synthetic resin in order to provide sufficient antibacterial properties, which may affect the properties of the synthetic resin. It's damaging and not economical. Furthermore, if the content of silver ions in the glass is 1.6% or more, metallic silver will precipitate when melting the soluble glass and damage the furnace, which is not economical, and furthermore, the particle size of the glass will be 5%.
If it is less than μm, the dissolution rate of silver from the resin becomes extremely slow, so it is necessary to add a large amount of soluble glass.
If the particle size is 60 μm or more, it may cause process troubles such as clogging when kneading into synthetic resin.
There is a risk of damaging the smoothness of the product surface.

分なる抗菌性が得られず、１０．０％以上の添加である
と、樹脂の特性、特に成形性を損なうおそれがある。As the synthetic resin for molding the contact lens solution container, any synthetic resin used for soft containers such as various polyethylene and polypropylene can be used. Additionally, the amount of soluble glass added to the synthetic resin varies depending on the properties of the synthetic resin and the expected antibacterial effect, but good results can be obtained by adding 0.3 to 10.0% (wt%) for boat fishing. . If the amount added is 0.3% or less, sufficient antibacterial properties cannot be obtained, and if the amount added is 10.0% or more, the properties of the resin, particularly the moldability, may be impaired.

おそれがある。Furthermore, since the amount of silver ions eluted from a container made of synthetic resin to which soluble glass has been added has the greatest effect on the antibacterial properties that are the object of the present invention, the amount was experimentally confirmed. In a test conducted in physiological saline at 20° C. for 24 hours, it was confirmed that an elution amount of 1 to 60 ng/cj was appropriate. That is, if the amount of silver ions eluted was less than log/ai, sufficient antibacterial properties could not be obtained, and depending on the type and number of bacteria, the proliferation of bacteria could not be inhibited. On the other hand, if the amount of silver ions eluted is 60 ng/d or more, there is a risk that the excess silver ions will react with the common salt in the solution, and a precipitate of silver chloride will precipitate out in the solution.
