Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a cold storage container,
More specifically, the present invention relates to a cold storage container used for storing fresh products such as vegetables, fruits and fish in a low temperature state.

[0002]

2. Description of the Related Art Conventionally, a box-shaped cold storage container made of styrene foam or the like has been used as a cold storage container for storing fresh products such as various vegetables and fishes in a low temperature state. In such a cold storage container, usually, both the upper surface and the lower surface of the opening are formed in a flat shape. Also, when storing cold storage containers containing vegetables and the like in a refrigerated warehouse, if you want to cool the contents, the upper and lower containers are stacked with their directions changed by 90 degrees and the cool air flows through the opening. Was formed.

[0003]

However, when the containers are stacked by changing the direction by 90 degrees, since the upper surface and the bottom surface of the opening are both flat, it is difficult to reliably stack the upper and lower containers. In some cases, the stacking state became unstable.

[0004] Therefore, the present invention, even if the direction of the upper and lower containers are changed in order to form a path of cold air,
It is an object of the present invention to provide a cold storage container capable of obtaining a stable stacked state.

[0005]

In order to achieve the above object, a cold storage container according to the present invention is provided with concave portions which are fitted to each other when the upper and lower containers are stacked while changing the direction of the upper and lower containers. It is characterized in that a projection is provided. Further, as another form of cold storage container, on the bottom surface of a rectangular container in a plan view, parallel to the short side, and the installation interval is equal to the interval of the long side upper edge of the container opening, the long side upper edge Is provided with two concave grooves having a groove width that can be fitted therein, and a concave portion is provided at an upper edge of the longitudinal side of the container opening to regulate a position at which the upper edge of the longitudinal side fits into the concave groove. It is characterized by that.

[0006]

1 to 3 show a first embodiment of a cold storage container according to the present invention. FIG. 1 is a perspective view from the container opening side, and FIG. 2 is a container from the container bottom side. FIG. 3 is a perspective view showing a state in which a plurality of cold storage containers are stacked.

[0007] The cold storage container 10 is formed in a rectangular box shape in plan view with the upper opening side expanded. At the center of the longitudinal side 12 of the container opening 11, a convex portion 13 protruding from the upper surface of the container is provided. On the container bottom surface 14, as shown in FIG. There are provided two concave portions 15 into which the convex portions 13 are fitted when stacked in a girder shape in the direction of rotation.

The projections 13 and the depressions 15 are set in a positional relationship such that when the two are fitted together and the cold storage containers 10 are stacked, the center of each of the cold storage containers 10 is located on a vertical line. Therefore, when cooling the contents in the refrigerated warehouse, as shown in FIG.
By sequentially stacking the cold storage containers 10 while fitting them, a plurality of the cold storage containers 10 can be stably maintained in a state where the ventilation holes 16 through which the cool air flows are formed on the short side of each of the cold storage containers 10. Can be accumulated.

FIGS. 4 to 6 show a second embodiment of the cold storage container of the present invention.
FIG. 4 is a perspective view as seen from the container opening side, FIG. 5 is a perspective view as seen from the container bottom side, and FIG. 6 is a perspective view showing a state in which a plurality of cold storage containers are stacked. .

The cold storage container 20 is formed in a rectangular box shape in a plan view with the upper opening side expanded, and two concave grooves 22 are provided in the container bottom surface 21. The two concave grooves 22 are parallel to the short side 23 of the container, and the installation interval is equal to the interval of the upper edge 24 of the long side of the container opening,
Further, the upper edge 24 of the long side has a groove width that can be fitted.

In addition, the upper edge 24 of the longitudinal side of the container opening has
Recesses 25 for regulating the fitting position into the concave groove 22 are provided respectively. The concave portion 25 has a length dimension of the concave groove 22, that is, a short side 23 on the container bottom surface 21.
Is formed in a length corresponding to the dimension of

As shown in FIG. 6, the thus formed concave groove 22 on the bottom surface of the container and the concave portion 25 on the upper edge of the longitudinal side are stacked in a grid pattern in a direction in which the cold storage containers 20 are rotated by 90 degrees. Sometimes, the upper edge 24 of the long side of the concave portion 25 is
Is fitted into the container so that the container bottom surface 21 straddles the upper edge 24 of the longitudinal side, and the container wall portions at both ends of the concave groove 22 contact the rising portions at both ends of the concave portion 25, so that the fitting positions of the two are regulated. Therefore, the upper and lower cold storage containers 20 are stacked at predetermined positions by the concave grooves 22 and the concave portions 25.

Further, the concave groove 22 and the concave portion 25 are set in such a positional relationship that when the two are fitted together and the cool containers 20 are stacked, the center of each cool container 20 is located on a vertical line. . Therefore, when the contents are cooled in the refrigerated warehouse, as shown in FIG.
By successively stacking the cold storage containers 20 while fitting each other, as in the case of the first embodiment, a plurality of cooling containers 20 are formed in a state in which ventilation holes 26 through which cool air flows are formed on the short side of each of the cooling containers 20. Can be reliably stacked in a stable state.

The projections 13 and the recesses 15 in the first embodiment and the recesses 22 and the recesses 25 in the second embodiment are arranged such that the upper and lower refrigerating containers are oriented at an angle other than 90 degrees, for example, 45 degrees. It is also possible to form such that a predetermined stacking state can be obtained while forming a cool air vent when changing and stacking. In the case where the legs are provided on the bottom surface of the container, the convex portions in the first embodiment can be provided on the bottom surface of the container, and the concave portions can be provided on the upper surface of the container. Further, the concave portion 25 in the second embodiment can be provided with two convex portions at predetermined positions without denting the upper edge 24 of the long side, and a concave portion can be formed between the convex portions.

[0015]

As described above, according to the cold storage container of the present invention, a stable stacking state can be obtained even when stacking by changing the directions of the upper and lower containers in order to form a passage for cool air.
