Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a natto container.

[0002]

2. Description of the Related Art Conventional natto containers are used for storing beans before ripening and then ripening them for shipment, and because natto cultivation requires air, a vent hole is provided in a lid or the like. Use containers that have the potential

[0003] However, those having such ventilation holes may cause inconveniences such as the incorporation of foreign substances such as insects and the evaporation of water more than necessary. For this reason, there is also known a container configured so that the ventilation holes are discarded and stored in a sealed state.However, these are aged without a lid, and after aging are closed by a method such as heat sealing. There is a possibility that foreign matter may be mixed in the manufacturing process.

Further, each corner portion of the upper surface of the flange of the container body and the lid plate are heat-sealed, and a plurality of dot-shaped convex portions are protruded from the inner surface of the upper surface of the flange of the unsealed portion at intervals in the inside and outside directions. To provide a ventilation gap in the non-seal part,
It is also known that the stored beans are aged and the unsealed portion is sealed and sealed.

[0005]

The above-mentioned container can prevent foreign matter such as insects from being mixed as much as possible. However, when resealing, a non-fused portion is easily formed around the dot-shaped convex portion. When the height is high, there is a possibility that a non-seal portion communicating between the inside and the outside may be formed.

Further, since each projection is provided at the center of the flange in the inward and outward directions, the lid edge adheres to the flange by the weight of the lid before resealing, thereby impeding good air permeability. There is a fear.

[0007] The present invention has been made in view of such a point, in the process of aging of the stored beans, it is possible to obtain a sufficient air permeability while preventing the entry of foreign substances from the outside, and finally the distribution Proposes an excellent natto container that can obtain a reliable hermeticity at the stage, reliably prevent foreign substances from entering from outside and cause unnecessary evaporation of water, etc., and has a simple structure and can be manufactured at low cost. It is.

Further, the container 1 of this embodiment has a secondary seal portion.
Before the fusion fixing of 9a, as shown in FIG.
The inside and outside of the container are communicated through a gap d between the cover plate 3a and the inner peripheral edge of the flange 7a, and as shown in FIG. 6, the inside and outside of the container are shut off after the secondary seal portion 9a is fused and fixed.

In the illustrated example, a pair of ventilation holes 11a is provided on each side, but one ventilation hole may be provided on each side. Further, each support wall 16 is provided with each ventilation hole 11.
a It is configured so as to be inclined inward from the outer peripheral edge to cover a part of the ventilation hole 11a.

FIGS. 9 to 12 show a fourth embodiment of the present invention, in which a peripheral wall 5b is erected from a bottom wall 4b peripheral edge, and an outer peripheral edge 17a is an inner peripheral edge outward from an upper edge of the peripheral wall. A container body 2b formed by extending a deformed flange 17 located at a level higher than 17b, and a seal portion 18 whose peripheral portion is fusion-fixed to the upper surface of the outer peripheral portion 17a of the deformed flange 17 are formed to open the upper end of the container body. It has a closed lid plate 3b.

Further, as shown in FIG. 10, the container according to the present embodiment has a bulging portion in which the inner peripheral edge portion 17b of the deformed flange bulges downward.
The bulging portion 19 is provided with a vent hole 11b which communicates with the outside of the container before aging the stored beans A, and which is closed by melting of the bulging portion 19 after the aging of the stored beans A.

As shown in FIG. 11, for example, as shown in FIG. 11, the ventilation flange 11 of the container body 2b to which the cover plate 3b is fused and fixed is sandwiched between upper and lower press plates 20 and 21 to close the lower hole. Only the press plate 21 is configured as a heating plate, and the bulging portion 19 around the ventilation hole 11b is heated and melted to close the ventilation hole 11b.

In this embodiment, the case where the hemispherical bulging portion 19 provided in the circumferential direction is provided on the inner peripheral edge portion 17b of the modified flange 17 has been described.
b A bulged portion provided in a groove shape over the entire circumference may be employed. The material of the container body 2b and the lid plate 3b can be the same as that of the embodiment of FIG.

[0026]

As described above, the natto container according to the first aspect of the present invention has the above-mentioned structure, so that during the ripening process of the stored beans, the inclined wall and the cover plate are reliably ventilated at a predetermined distance. Since the through hole is opened, sufficient air permeability can be reliably obtained, and in the final distribution stage, a secondary seal portion in which the inner peripheral portion of the primary seal portion is fusion-fixed to the upper surface of the inclined wall is provided. Because of this, the ventilation holes are completely closed, and a reliable sealing performance can be obtained, preventing the intrusion of foreign matter from the outside and the evaporation of moisture more than necessary, and the structure is simple and inexpensive. It can be manufactured.

Further, the natto container according to the second aspect of the present invention has an advantage that the lid can be easily opened without peeling off the fusion portion between the lid plate 3 and the flange 7 of the container body 2.

In the container according to the third aspect of the present invention, in the process of ripening the stored beans, the ventilation holes 11a inside the flanges 7a are reliably opened by the support walls 16 erected on all sides of the flanges 7a. Sufficient air permeability can be surely obtained, and in the final distribution stage, the flange 7a inside the ventilation holes 11a
Since the secondary seal portion 9a in which the inner peripheral edge portion of the primary seal portion is fusion-fixed to the inner peripheral edge portion on the upper surface is formed, the ventilation hole 11a is formed.
Is completely closed, and a secure airtightness can be obtained, preventing the entry of foreign matter from outside and the evaporation of moisture more than necessary,
Moreover, the structure is simple and can be manufactured at low cost.

In the natto container according to the fourth aspect of the present invention, during the ripening process of the stored beans, the inner peripheral edge portion 17b of the irregularly shaped flange and the top plate 3b open the ventilation hole 11b with a predetermined distance therebetween. Therefore, sufficient ventilation can be reliably obtained, and in the final distribution stage, since the ventilation holes 11b are closed by melting of the bulging portion 19, reliable sealing can be obtained. As a result, it is possible to reliably prevent foreign substances from being mixed in from outside and evaporate more moisture than necessary, and the structure is simple and can be manufactured at low cost.
