〔産業上の利用分野〕
本発明は医薬品や食品等の包装容器の内部の紫外線殺菌
装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in an ultraviolet sterilization device for the inside of packaging containers for pharmaceuticals, foods, etc.
従来、目薬等の医薬品やミネラルウォーター等の食品を
容器に充填する作業は一般にクリーンルームで行い、こ
の注入作業の前には容器の内部の殺菌が行われる。Conventionally, filling containers with medicines such as eye drops or foods such as mineral water is generally performed in a clean room, and the inside of the container is sterilized before the filling operation.
容器の内部の殺菌は例えば紫外線２５４ｎｍを照射し容
器に付着する大腸菌、枯草菌、緑膿菌等を殺菌すること
が行われている。The inside of the container is sterilized by, for example, irradiating it with ultraviolet light of 254 nm to kill Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, etc. that adhere to the container.
ところが医薬品や食品等に紫外線が長時間照射されると
、医薬品等が変質するので、容器は紫外線を透過しない
例えばポリエチレンテレフタレートを材料として構成し
たものが実施されている。However, if medicines, foods, etc. are irradiated with ultraviolet rays for a long period of time, the medicines, etc. will change in quality, so containers made of, for example, polyethylene terephthalate, which does not transmit ultraviolet rays, are used.
しかし容器の充填口が狭い場合は、充填口から紫外線を
照射しても紫外光の影になる部分は殺菌されず、残存し
た大腸菌が繁殖する欠点がある。However, if the filling opening of the container is narrow, even if ultraviolet rays are irradiated from the filling opening, the areas in the shadow of the ultraviolet light will not be sterilized, and the remaining E. coli bacteria will proliferate.
本発明は上記の点に鑑み発明したものであって、医薬品
や食品等の容器の内部に紫外線透過率のよい液体を充填
し、液体中での光の散乱を利用し、紫外線の照射されな

線殺菌装置を提供することを目的とする。The present invention was invented in view of the above points, and the present invention is made by filling a liquid with high ultraviolet transmittance inside a container for pharmaceuticals, foods, etc., and utilizing the scattering of light in the liquid to prevent ultraviolet rays from irradiating the area. The purpose of the present invention is to provide an ultraviolet sterilizer that can effectively sterilize E. coli and other bacteria.

is, for example, a cylindrical container filled with medicines or foodstuffs, and the filling opening is narrower than the cylindrical portion. The container is made of, for example, polyethylene terephthalate, which does not transmit ultraviolet rays. 3 is a liquid filled in the container 2, such as pharmaceuticals such as eye drops, foodstuffs such as mineral water, and industrial water such as pure water. 4 is an ultraviolet irradiator located above the container 2; 5 is an ultraviolet irradiator 4;
This is an ultraviolet germicidal lamp that is installed inside the.

中に液体は入れてない。Results of experiments of the present invention [The irradiation time was varied by adjusting the conveyor speed. ]B Conventional ultraviolet sterilizer The present invention and (a) to (*) and ()) are under the same conditions; no liquid is placed in the container.
従来の紫外線殺菌装置の実験結果
上記実験の結果、本願発明に係る紫外線殺菌袋６０秒で
全部死滅する。Experimental Results of Conventional Ultraviolet Sterilization Device As a result of the above experiments, the ultraviolet sterilization bag according to the present invention is completely killed in 60 seconds.
これに対し従来の紫外線殺菌装置によると紫外光の影に
なる大腸菌が死滅しないため６０秒経過しても約１割生
菌数が残り、９０秒経過しても大腸菌の殺菌率は低いこ
とが判る。In contrast, with conventional ultraviolet sterilizers, the E. coli in the shadow of the ultraviolet light is not killed, so approximately 10% of the viable bacteria remain after 60 seconds, and the sterilization rate of E. coli is low even after 90 seconds. I understand.
なお容器の中に充填した液体が、医薬品、食品等の場合

するので、上述のごとく、紫外線の影になる部分の大腸
菌も短時間に効果的に殺菌することができる利点を有す
る。In addition, if the liquid filled in the container is a medicine, food, etc., it is sealed as it is after sterilization, and if the liquid inside the container is not needed, it is drained and the necessary liquid is replaced. The inside of the container is filled almost completely with a liquid with good UV transmittance, and the liquid is irradiated with ultraviolet rays from the filling opening of the container.
Since the inside of the container is sterilized by using the diffused ultraviolet rays inside the liquid, it has the advantage that even E. coli in areas shaded by the ultraviolet rays can be effectively sterilized in a short period of time, as mentioned above.
