Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 According to the present invention, food such as a lunch box or a side dish placed in a container can be directly cooked in a microwave oven, and further, fermented fermented boiled soybeans in a container can be used to produce natto, and can be used as it is. The present invention relates to a food container that can be put on a distribution mechanism in a state.

[0002]

[Prior art]

 When a conventional box lunch or prepared food is cooked in a microwave oven, a part of the lid of the container is peeled off or a small hole is opened in the lid to release steam in order to prevent the container from bursting. In the production of natto, natto is fermented and then put into a plastic container or a paper container and shipped to the market. In the case of natto production, in recent years, the method of putting steamed soybeans in small containers, covering with lids, fermenting the fermented soybeans in that state to produce natto, and then shipping the product directly to the market has been widely adopted from the standpoint of food hygiene. . Natto immediately after fermentation contains a lot of water, and it is necessary to release the water out of the container.Also, it is necessary to take in oxygen from the outside of the container for fermentation. Those that have had been adopted. However, there is a problem that the lid material having air permeability and moisture permeability is inevitably thin and has a poor appearance.

[0003]

[Problems to be solved by the invention]

 The present invention has been made to solve the above problems, and its purpose is to prevent intrusion of garbage and fine insects into a food container containing a lunch box or prepared food. It can be cooked in a microwave oven in the container, and in the case of natto manufacturing, it can be used without limiting the air permeability and moisture permeability as the lid material of the natto container. Food that can improve the appearance in the market because it can also adopt a lid material, and that can be fermented in the container and prevent invasion of garbage and fine insects into the natto container. To provide containers for use.

[0004]

[Means for Solving the Problems]

 That is, the food container according to the present invention is a food container having a flange portion around the outside, the outer projection projecting upward from the upper surface of the flange portion and having a recess at a predetermined interval, and the outer projection inside the outer projection. An inner ridge having substantially the same height as the ridge and having recesses at predetermined intervals is provided, and the positions of the recesses of the outer ridge and the inner ridge are shifted from each other. The height of the outer ridge and the inner ridge is 0.1 to 3.0 mm, and the length of the concave portion in the circumferential direction of the outer ridge and the inner ridge is 0.1 to 3 mm. 0 mm.

[0005]

[Embodiment of the invention]

 Hereinafter, a food container according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the food container according to the present invention as viewed from the top side, and FIG. 2 is a partially enlarged view of a flange portion of the food container according to the present invention. In the drawing, reference numeral 1 denotes a food container, 1a denotes a flange, 1b denotes a container, 1c denotes an outer ridge, 1d denotes an inner ridge, 1e and 1f denote recesses.

[0006] The lid material (not shown) used for the food container of the present invention may be a thick material regardless of air permeability or moisture permeability. The lid is fixed to the upper surface of the outer ridge and the inner ridge of the food container of the present invention by heat fusion or adhesion. Therefore, in order to use the food container according to the present invention, a lunch box or prepared food can be put in the container and the lid can be fused or adhered as it is. After inoculating natto and inoculating natto, the lid material is fixed, fermented in that state, and can be shipped directly to the market. At that time, the material of the lid material is free, and printing that appeals to purchase can be freely performed, so that the commercial value can be improved.

As shown in FIGS. 1 and 2, the food container 1 according to the present invention includes a flange 1a and a container 1b for storing food. In the case of putting a lunch box or a prepared dish, after putting the food in the food container 1, a lid (not shown) may be heat-sealed or adhered as it is. When the food placed in the food container 1 is electronically heated, a large amount of steam is generated. The generated steam passes through the concave portion 1f of the inner ridge 1d and is formed by the outer ridge 1c and the inner ridge 1d. The food is discharged from the recess 1e of the outer ridge 1c provided on the upper surface of the food container 1 through the groove, so that the food container 1 does not burst. In the case of producing natto, the steamed soybeans may be fermented with natto bacteria after the steamed soybeans are placed in the food container 1 and the lid material is fixed by fusing or bonding. Oxygen is required to ferment natto, but air enters through the recess 1e of the outer ridge 1c provided on the upper surface of the food container 1. However, the inner ridge 1d is provided on the inner side, and the recess 1f of the inner ridge 1d is located at a position deviated from the recess 1e of the outer ridge 1c. It passes between the grooves formed by the ridges 1d and enters the inside of the natto container 1 from the concave portion 1f of the inner ridge 1d. Therefore, when the food container 1 has a rough surface, it is easier to form a contact space with the steamed soybean than in a flat container, so that the fermentation rate is increased or the strength of the food container 1 is increased. It is an effective means.

[0008]

[Effect of the invention]

 Since the food container of the present invention is configured as described above, it has the following effects. (1) According to the food container of the present invention, a large amount of steam generated during cooking by the microwave oven can be released to the outside through the concave portion of the inner ridge and the concave portion of the outer ridge. There is no need to peel off parts or make small holes in the lid, and the food can be electronically cooked in the container. (2) According to the food container of the present invention, oxygen can be supplied via the lid and the concave portions of the outer ridges and the inner ridges of the food container. Natto can be fermented in a container after seeding the natto. (3) According to the food container of the present invention, steam is released or oxygen is supplied via the concave portion of the outer ridge and the concave portion of the inner ridge of the food container which is fused or adhered to the lid material. Therefore, it is possible to prevent garbage and minute insects from invading, which is sanitary. (4) According to the food container of the present invention, since the lid material is not limited, printing and the like can be performed freely, and a food container that appeals to purchase can be provided.
