Description

The present invention relates to a method for producing a packaging bag having a chuck and a spout and made of a film, which is sterilized and filled in the sterilized state.

Currently, for foods, beverages, medical drugs, etc., packaging materials without a spout are sterilized by immersing the packaging material in a chemical solution such as hydrogen peroxide solution.
In addition, there is an example of a pouch with a spout having a large diameter, in which the spout is attached while making a bag and sterilized by irradiating an electron beam.
In addition, there is also an example in which a sterilized packaging bag is manufactured by sterilizing the spout by immersing it in a chemical and then fusing the spout while making a packaging bag with a film immersed in the same chemical.
When the spout is occluded, it is difficult to sterilize by infiltrating the drug into the inside of the occluded spout by the method of immersion sterilization with a drug. Even if the drug can be infiltrated and sterilized inside the closed mouth plug, it is even more difficult to remove the drug in a short time.
For example, the Food Sanitation Law stipulates that hydrogen peroxide solution used for sterilization must not remain in food containers.
Similarly, when the chuck is fitted, it is difficult for the drug to permeate and it is not easy to remove the drug in a short time.

For example, in Patent Document 1,
We propose a sterilization method for the spout plug that removes the sterilization liquid by spraying heated clean air after sterilizing the spout plug by spraying a sterilizing solution before the mounting process of the spout plug.
However, in this method, it is necessary to sterilize each time it is attached, which is complicated and very time-consuming. Moreover, it is difficult to remove the bactericidal solution inside in the case of a closed spout by simply spraying heated clean air.

Further, in Patent Document 2,
A chute-type cap sterilization and cleaning device that sterilizes and cleans the cap by injecting a sterilization and cleaning medium onto the cap being transported by the chute with an injection nozzle, using an ascending chute whose transport path is inclined with respect to the horizontal plane. We have proposed a sterilization and cleaning device for caps in which a sterilization and cleaning medium pipe having a plurality of injection nozzles is arranged and a chute is arranged in a zigzag shape in the height direction by arranging an ascending slope chute and a vertically descending chute in succession.
However, even if the mist-like sterilization and cleaning medium sprayed in this way is used and the product moves in a zigzag manner and the medium is difficult to collect, it is difficult to remove the sprayed and wet sterilization and cleaning medium in a short time. It was.
