[Industrial applications]

 The present invention relates to the structure of a natto container that is used consistently from the production line to the sales route.

[0002]

[Prior art]

 Natto has been distributed in the people's lives since ancient times as a health food that matches the Japanese diet. Natto is a fermented food made by breeding soybeans with natto bacteria.Currently, the manufacturing method of natto is such that boiled beans are quantitatively divided and packaged in a container, and the temperature and humidity are automatically adjusted in the fermentation chamber. In addition, continuous automation is in progress by line production for all manufacturing processes until the completed products are cooled. Therefore, there is still some traditional manufacturing method using straw and warp, but it is desired to develop new containers according to the progress of the times. However, regarding the continuous automatic natto manufacturing method by making a line, in order to incorporate the process of mixing natto bacteria in steamed soybeans, putting this in a container and fermenting it in a fermentation room into a consistent production line, The structure had many difficulties.

That is, as a conventional cup container, a container is used in which a paper container in which a plastic film is laminated on the inner surface of a container made of paper is coated with a film body having a perforated upper part of the container. For Bacillus natto mixed in soybeans enclosed in the container, the external conditions of temperature and humidity suitable for germination and growth of Bacillus natto and the internal conditions of supplying oxygen into the cup container are required. Bacillus natto is an aerobic bacterium, and in terms of the culture environment in which oxygen is given to the container in the cup to enhance the fermentation action, the conventional paper container had a container structure in which only the top seal at the mouth of the container was perforated. Since the culture environment, that is, the supply of oxygen is not sufficient, there is a drawback in that the productivity of the automatic line does not increase.

Further, since the perforation of the top seal has been mechanical perforation in the past, film slag generated during perforation may be mixed in the natto or attached to the film surface, and the perforation accuracy is non-uniform, which leads to sanitary However, there is a problem in that the quality of manufacturing is deteriorated.

[0005]

[Problems to be solved by the present invention]

 The present invention solves the above-mentioned problems by firstly supplying oxygen appropriately in the container, and secondly providing a uniform culture environment for Bacillus natto mixed in the container. Thirdly, in the hole making technique, it is an object to make a container structure that eliminates the sanitary aspect such that the slag remains or is attached.

[0006]

[Means for Solving the Problems]

 As a means for achieving the above object, the present invention relates to a structure of a natto container in which a plastic film having a hole having a diameter of 100 μm to 1.000 μm is laminated on the inner surface of the container by a technical means developed by the applicant.

[0007]

[Action]

 The container has a 100 μm to 1.000 μm perforated hole laminated on the inner surface of the vessel, and the effective rate is 0.8% to 6.5%. Fermentation efficiency was improved by the supply of oxygen to promote fermentation. Moreover, since the perforated holes are provided all around the inside of the vessel, a uniform fermentation action is achieved. In addition, it has the effect of improving the sanitary aspect without the residue and sticking that occurs during conventional drilling.

[0008]

【Example】

As shown in the drawings, 10 is a container for natto of the present application, 11 is a container body of a paper box, and 12 is a plastic seal body attached to the mouth of the container. 13 is a plastic film laminated on the inner surface of the container body. The film body is a sheet body having a perforated hole 14 according to the know-how developed by the applicant and having a hole diameter of 100 μ to 1.000 μ, and the hole occupancy rate is 0.8% to 6.5% of the whole and the hole is present. The number of holes is 1.1 million / m ² to 110,000 / m ² . This sheet body, which is a film body, is made of a polyethylene single-layer film, such as polyethylene, polyester or the like, suitable for perforating holes, or a multilayer film of these single-layer films. Note that the plastic seal body adhered to the mouth of the container may be a top seal having a hole.

[0009]

【effect】

 Since the natto container according to the present invention has the above-described structure, it has an advantage that the container body is breathable and the fermenting action of the natto bacterium in the container is stimulated by the supply of oxygen from the outside to accelerate the ripeness effect. The promotion of the ripeness effect improves the productivity of natto, and the mass-production of natto helps reduce the production cost. Moreover, since the culture environment for fermentation is uniform and uniform, high quality natto is produced and natto suitable for the taste preference of the user is provided. Furthermore, since the invasion of various bacteria and insect damage and the mixing of residues were eliminated, it is a hygiene-friendly container for natto that is easy to control fermentation. It is useful for automation by the production line and for quality control and storage control by the sales route. And its practicality is remarkable.
