Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Field of Application" The present invention relates to a miso packaging bag made of a plastic sheet and filled with miso without using preservatives or fermentation inhibitors such as alcohol.

``Prior art'' When miso without fermentation inhibitors is sealed in a plastic sheet bag, it is filled with fermentation gas and the bag is damaged. Therefore, when sealing the bag in the bag as described above, a fermentation inhibitor is used to prevent fermentation within the bag.

``Problems to be Solved by the Invention'' A fermented gas outlet is provided in a miso packaging bag made of a plastic sheet to enable filling of miso without using a fermentation inhibitor, and a method is provided to diffuse the gas flowing out from the outlet. This prevents small flies from gathering at the outlet, prevents dust from adhering to the outlet and causing unsanitary conditions, and prevents mold from forming on the top of the filled miso. I tried to avoid it.

``Means for solving the problem'' A peripheral wall is raised from the periphery of the bottom wall, and the inside thereof is filled with fermented miso without the use of fermentation inhibitors.
Bag made of non-breathable plastic sheet 1
Then, overlap the plastic sheet portions forming the bag opening 2, leaving the outlet 4 for fermentation gas from the miso so as to be openable at a part of the upper edge of the bag opening, and overlap the plastic sheet parts forming the bag opening 2. The bag mouth closing means 3 whose parts are adhered to each other, and the outer surface of the bag mouth are covered with a bifold sheet placed over the bag mouth including the upper end of the fermentation gas outlet, and the inner surface of the sheet is covered with the bag mouth. A mouth covering sheet 5 attached to the outer surface of the mouth;
The bottom wall section includes a fermentation gas diffusion path 6 formed between the bag opening and the inner surface of the opening covering sheet so that the fermentation gas flowing out from the outlet 4 can be diffused and discharged outward. was provided so as to be able to stand up as a surface to be placed on a table or the like.

"Function" Fermented gas is generated from the soybean paste described above, and is released into the atmosphere through the outlet 4 and further through the fermented gas diffusion path 6. Space above miso inside bag 1 and outlet 4
The interior is filled with carbon dioxide gas as a generated gas, and the carbon dioxide gas prevents oxygen from flowing in, thereby preventing mold from forming on the surface of the miso.

"Example" 1 is a non-breathable plastic bag with a peripheral wall rising from the periphery of the bottom wall, and the bag is filled with fermented soybean paste without using a fermentation inhibitor.
The bag opening is closed leaving an outlet 4 for fermentation gas from the miso. The blockage, as shown in Figure 2,
Both the left and right parts 2a, 2a of the upper part of the bag peripheral wall are folded inward to the mouth part leaving a gap between the tips of the two parts, and the overlapping parts excluding the gap part are bonded 3. In this case, the gap portion forms the fermentation gas outlet 4. The mouth covering sheet 5 may be a plastic sheet, but is preferably paper because of its breathability and ease of printing for product descriptions. The mouth covering sheet 5 is preferably attached to the bag mouth on both lower inner surfaces of the sheet. The fermentation gas diffusion path 6 can be formed between the upper edge of the bag mouth, the inner surface of the non-attached portion of the mouth covering sheet, and the outer surface of the bag mouth.

The bag 1 filled with miso is provided so that the aforementioned bottom wall portion stands up as a surface to be placed on a table or the like.

"Effects of the Invention" Since the fermentation gas outlet and the fermentation gas diffusion path are provided, fermentation gas is discharged and the gas is filled even if the miso without fermentation inhibitor is filled into the bag made of plastic sheet. Since the bag is made of plastic and is designed to stand up, the moisture contained in the miso will not seep out to the outside of the bag and pollute the surrounding area. Since it is covered with a bi-folded sheet placed over the bag opening, and the inner surface of the sheet is attached to the outer surface of the bag opening, it is possible to diffuse and discharge the fermentation gas flowing out from the outlet. To,
Since the fermentation gas diffusion path 6 is provided between the bag opening and the inner surface of the mouth covering sheet, there is no possibility that small flies will gather at the fermentation gas outlet, and there is no risk of dust etc. entering from the outlet. . Since the above-mentioned gas is diffused and released from the fermentation gas diffusion path, small flies and the like will not gather at the release portion.

The fermentation gas mentioned above is carbon dioxide gas, and since carbon dioxide gas has a higher specific gravity than air, the air in the space above the miso inside the bag when the bag mouth is closed is pushed upward by the carbon dioxide gas generated from the miso. The inside of the bag is always filled with carbon dioxide gas. Miso naturally has a tendency to grow mold, which significantly reduces consumers' desire to purchase it.
As described above, the inside of the miso packaging bag according to the present invention is filled with carbon dioxide gas, so by providing oxygen deficiency in this way, it is possible to prevent the miso inside the bag from growing mold.

Furthermore, as the miso ripening progresses, the amount of carbon dioxide gas generated also decreases, but since the bag is set up so that the bottom wall of the bag stands up when it is filled with miso, the slight amount of carbon dioxide that is generated is reduced. Gas is also stored inside the bag, in the space above the miso and in the outlet 4, and stagnates.As a result of carbon dioxide gas being stored in the miso filling bag in this way, the growth of mold is prevented for a long time even after the miso is ripened. It can be prevented.
