Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing, for example, coffee beans in a freshly roasted state for a long period of time.

[0002]

2. Description of the Related Art When drinking coffee, it is almost impossible to roast coffee beans each time. Therefore, usually, a required amount is roasted, put in a container and stored in a refrigerator.
Refrigeration prevents oxidation and keeps freshness for a long time. This refrigerated storage is performed not only at home but also at coffee restaurants.

As shown in FIG. 7, the conventional storage container is generally one in which a lid 2 is fitted on the container body 1 so as to be slightly solid. When this container P is taken out of the refrigerator and the lid 2 is opened, as shown in FIG. 8, since the temperature of the container P is lower than that of the outside air, the surrounding air is cooled and the water content becomes water vapor, so that the air becomes moist. Become. The moist air a rises and enters the inside from the upper edge of the container body 1 as shown by the arrow in the figure, and moistens the coffee beans therein. This moistening reduces the freshness of coffee beans and makes them unpalatable no matter how they are made. In other words, the deliciousness of delicious coffee greatly affects the freshness of the beans.

An object of the present invention is to maintain freshness of freshly brewed coffee beans and the like for a long period of time.

[0005]

To solve the above object, according to an aspect of, in this invention, a bottomed outer tube, inner tube disposed concentrically with a gap around, the inner cylinder, the Up
Part is out outer cylinder or et collision, projecting edge of that is touching the upper edge the outer cylinder
The inner cylinder is provided with an inner lid that closes the opening, and the outer cylinder is provided with an outer lid that fits the outer surface of the inner cylinder.

In this structure, when the outer lid is fitted, the upper inner surface of the outer lid may contact the outer upper surface of the inner lid.

[0007]

The storage container according to the present invention having the above-described structure stores, for example, freshly brewed coffee beans in an inner cylinder, covers the inner lid and the outer lid, and puts it in a refrigerator for storage. At this time, if the inner upper surface of the outer lid is in contact with the upper outer surface of the inner lid and the inner lid is pressed against the inner cylinder, airtightness is maintained in the inner cylinder. For this reason, when the temperature is lowered, it is usually dried by the release of the water vapor due to the vaporization of water, but since it is airtight, it is not released and the inside of the inner cylinder is not dried, and the coffee beans keep their freshness.

When using the stored items (coffee beans), both lids are opened as usual. At this time, the outside air comes into contact with the cooled container, steam is generated around the outside, and the steam (wet air) rises on the outer peripheral surface of the outer cylinder. However, the rising air diffuses to the upper edge of the outer cylinder to some extent due to the presence of the gap between the inner and outer cylinders, that is, the air layer. The moist air that has reached the outer peripheral surface of the inner cylinder continues to rise, but since the upper edge (protruding edge) of the inner cylinder is bent outward, the traveling direction is directed outward along the bend and inside the inner cylinder. There will be as few as possible. Therefore, when the lid is opened, the stored items are prevented from being wet and the freshness is maintained.

When the required amount of the stored items has been taken out, the inner and outer lids are covered and refrigerated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment is shown in FIGS. 1 to 3, and as shown in FIG. 2, this embodiment has a bottomed outer cylinder (diameter: 123 mm,
Height: 121 mm) 10, inner cylinder (diameter: 110 mm, height:
155 mm) 11 and their lids 12 and 13, inner and outer cylinders 1
The heat insulating material 14 is interposed between the first and the tenth. The inner and outer cylinders 10 and 11 and the lids 12 and 13 are made of an aluminum plate having a thickness of 0.8 mm, but may be made of other metal, for example, stainless steel or the like, or may be a plastic molded product, wood, or the like. Also, the shape and size are appropriately set depending on the type and amount of the stored items.

The upper edge 11a of the inner cylinder 11 is the outer cylinder 10.
In a state of being concentrically placed, the outer edge is bent in an arc shape with a point of about 30 mm from the upper edge as a base point. This bent portion 11a
As a result, the gas that rises on the outer surface of the inner cylinder 11 is prevented from entering the inner cylinder 11 with its direction facing outward. Bend 1
1a is not an arc shape, but is shown in FIGS. 5 (a), (b), (c).
As described above, it may be bent at a right angle, bent in an oblique straight line, bent in a downward arc, or the like, as long as it has a shape in which the upward airflow is directed outward. The bending position is 30 above.
The size is not limited to mm, and may be appropriately set depending on the size and height of the inner and outer cylinders 11 and 10.

The heat insulating material 14 is not limited to the bubble-containing sheet shown in the figure, but various materials such as styrofoam can be adopted. By interposing the heat insulating material 14 between the inner and outer cylinders 11 and 10, the heat insulating effect in the inner cylinder 11 is achieved and the outer cylinder 1
The inner cylinder 11 is positioned concentrically with respect to 0. The inner cylinder 11 may be fixed to the outer cylinder 10 at its bottom surface.
One bottom surface can be removed. The heat insulating material 14 includes inner and outer cylinders 11 and 10.
Can also be interposed between the bottom surfaces of the, or can be completely eliminated.

The inner lid 13 is fitted in the bent portion 11a of the inner cylinder 11 to make its opening airtight, and when pushed, its airtightness is enhanced.

The outer lid 12 is fitted to the outer peripheral surface of the outer cylinder 10 with a degree of adhesion such that it can be removed. In the fitted state (covered state) as shown in FIG. The inner lid 13 is pressed against the upper and outer surfaces. The contact point may be the entire circumference, as shown by the solid line in the figure, or may be the central part, as shown by the chain line. If it is the entire circumference,
It is preferable because it covers a wide range so as to wrap it.

In this storage container S, as shown in FIG. 1, freshly brewed coffee beans b are stored in an inner cylinder 11 while being kept in the bag, covered with an inner lid 13 and an outer lid 12, and then stored in a refrigerator. Put in and save. At this time, since the outer lid 12 presses the inner lid 13 and presses the inner lid 11, the inner lid 11 is kept airtight. For this reason, the steam in the inner cylinder 11 is not dried due to the steaming due to the steaming due to the temperature decrease, and the coffee beans b
Keeps freshness.

Further, the coffee beans b are used by opening the both lids 12 and 13, and at this time, as shown in FIG. 4, outside air comes into contact with the cold container S, and water vapor is generated around the outside so that it becomes damp. The air a rises on the peripheral surface of the outer cylinder 10. However, the ascending air a diffuses to the upper edge of the outer cylinder 10 due to the presence of the gap (air layer) between the inner and outer cylinders 11 and 10. The moist air a reaching the outer peripheral surface of the inner cylinder 11 continues to rise, but when it reaches the bent portion 11a at the upper edge of the inner cylinder 11,
The direction of travel of the inner cylinder 11 is outward along the bend.
There will be as few as possible inside. Therefore, the lids 12, 1
When the coffee beans 3 are opened, the wetness of the coffee beans b is prevented and the freshness is maintained.

When the required amount of coffee beans b has been taken out,
Cover the inner and outer lids 13 and 12, and store in a refrigerator. The coffee beans should be left for a while and then ground and eaten. The coffee is deliciously freshly brewed.

As in the embodiment, the inner and outer cylinders 11 and 10 are
Etc. made of aluminum, aluminum has good thermal conductivity.
The temperature is relatively fast and becomes equal to that of the surroundings, and there is an advantage that water vapor is generated for a short time.

Further, as shown in FIG. 6, if the inner lid 13 is made of a heavy material such as stainless steel or ceramic, the inner lid 13
Is pressed against the inner cylinder 11 by its own weight, so that the outer lid 1
Inner upper surface of the 0 have to be necessarily abut on the outer upper surface of the inner lid 13 is not Na.

Although the storage of coffee beans has been described in the embodiments, it goes without saying that the storage container S according to the present invention can be used for storing various things such as seaweed and hail cakes.
