Conventionally, this type of sterilization bag has been made of a non-breathable sheet or film (hereinafter referred to as
Short linear cuts (hereinafter referred to as - marked cuts) 4 at regular intervals in the direction of the opening edge 3 on either the front or back side of the bag body 2 consisting of a non-breathable sheet) 1. are engraved in the vertical or horizontal direction, and these multiple -
A tape 5 made of a breathable material that does not allow germs to pass is applied to the inner side of the bag body 2 so as to cover the cut 4 of the mark, and both left and right ends of the tape 5 are placed between the left and right seal portions 6 and 7 of the bag. In the soldered state, it is heat-sealed to the air-impermeable sheet 1 of the bag body 2, and the upper and lower longitudinal edges 8, 9 of the tape 5 are heat-sealed to the air-impermeable sheet 1.

に使用される。 Therefore, such sterilization bags are filled with the contents, such as Komaki for cultivating shiitake mushrooms, and sealed, and the inside of the bag is steamed using, for example, talk crepe (a pressure- and heat-resistant container used for reactions and extractions at high pressure and high temperature). After sterilization, it is opened in a clean room, injected with Shiitake bacteria, resealed, and used for purposes such as cultivating Shiitake bacteria.

However, in the above-mentioned conventional sterilization bag, the cut cut in the non-breathable sheet 1 at the position where the tape 5 made of a breathable material that does not allow bacteria to pass is a cut marked with a - mark. The problem is that the tape is made of a breathable material that has poor air permeability, water permeability, moisture permeability, etc. and is impermeable to bacteria, causing bacteria to grow inside the bag or causing the bag to break during steam sterilization. It was hot.

を完成するために至つたものである。 In order to solve these problems, we have improved the air permeability (rate), water permeability (rate), moisture permeability (rate), and tightness (rate) of tapes made of breathable materials that do not allow bacteria to pass through.
As a result of various experimental studies on the degree of bacterial reproduction inside the bag (rate) and the rate of bag breakage during steam sterilization, we found that there is ×, *, +, on the breathable sheet
When you make a three-dimensional cut like the mark, the cut part opens most effectively and effectively, improving breathability.
It can improve water permeability and moisture permeability, but +,
In the case of a mark such as a mark in which another cut line is located on the extension line of one cut line, when multiple cuts are made at regular intervals in the longitudinal direction, steam sterilization starts from the cut part. In addition, in the case of a V-shaped cut, there is a possibility that the bag will open three-dimensionally around the intersection where the cross mark or * mark is in the center, but it will open at one end. Since it opens only from the top, in order to obtain the same degree of dimensional opening as the cuts marked with an " It was discovered that the V-shaped cut portion could get caught during filling, leading to bag breakage, and this idea was developed.
