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 Hitherto, as a cold storage container for storing fresh products such as various vegetables and fishes in a low temperature state, a box-shaped cold storage container with a lid made of styrene foam or the like has been used. The lid in such a cold storage container is formed so that the lid fits in an airtight state in the upper opening of the cold storage container, and one is an upper surface, the other is a lower surface (inner side).
The direction of attachment to the container body was also determined.

[0003]

Therefore, when storing the cold storage container in which vegetables and the like are stored in a refrigerated warehouse, if it is desired to cool the contents, the lid is removed from the container body or shifted. It must be kept in a state where cold air flows into the container. In addition, when cooling the contents by stacking the containers, it is necessary to change the angle of the container body with the lid removed, and stack the containers. For this reason, the floor area at the time of stacking becomes larger than usual,
It was necessary to move the pallet used for transportation or the like to another place for cooling, and the removed lid had to be separately stored and managed.

Accordingly, an object of the present invention is to provide a cold storage container that can efficiently cool contents and can easily stack contents.

[0005]

Means for Solving the Problems In order to achieve the above object, the present invention provides a cold storage container comprising: a container main body; and a lid attached to an upper opening of the container main body.
A concave portion is provided on the container main body side of the mating surface of the container main body and the lid, and a convex portion corresponding to the concave portion is provided on the lid side, and when the lid is inverted and attached to the container main body, the concave portion is a container. It is characterized in that it serves as a ventilation port communicating between the inside and outside, and further, holding portions for holding the bottom surface of the container body are provided on both sides of the lid.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a cool container according to the present invention. FIG. 1 is a front view showing a cool container in which a container body is sealed with a cover, and FIG. 2 is an inverted cover. FIG. 3 is a front view showing a cold storage container in a state of being attached to a container main body, FIG. 3 is a cross-sectional side view of a main part showing the cold storage container in a state where the container main body is sealed with a lid, and FIG. FIG. 5 is a cross-sectional side view of a main part showing the cold storage container attached to the main body, and FIG. 5 is a perspective view showing a state where a plurality of cold storage containers are stacked.

The cold storage container 10 comprises a box-shaped container main body 11 having an open upper side which is widened, and a plate-like lid 12 which is attached to the upper opening of the container main body 11 and has a rectangular shape in plan view. In the mating surface of the container body 11 and the lid 12, a concave portion 13 on the upper edge of the container body and a concave portion 13 on the lower surface of the lid 12 correspond to the central portion on the long side facing the opposite side. Protrusions 14 are provided respectively.

As shown in FIG. 1, when the lid 12 is mounted on the container body 11 in a normal direction, that is, in a direction in which the upper opening of the container body 11 is sealed, The concave portion 13 and the convex portion 14 are fitted to each other to
1 and the lid 12 are brought into close contact with each other to prevent outside air from flowing into the cold storage container 10 through the gap.

Further, since the peripheral edge on the upper surface side of the lid 12 is formed in a flat shape like a normal lid, as shown in FIG. A vent 15 is formed between the recess 13 and the lid 12 to allow communication between the inside and outside of the container. Therefore, when cooling the contents in the refrigerated warehouse, the lid 12 is turned over to be in a state of being attached to the container body 11, so that cool air flows into the container through the vent 15 and the contents are cooled. Things can be cooled. This eliminates the need to remove the lid 12 from the container body 11, so that there is no need to separately store and manage the lid 12, and the lid 12 is not lost.

Further, projecting portions 16 and 17 are provided on both sides of the lid 12 in parallel with the periphery of the lid. The outer peripheral side edges of the protruding portions 16 and 17 are set at positions corresponding to the inner peripheral edge of the upper opening of the container main body 11, and the inner peripheral side edges correspond to the bottom outer peripheral edge of the container main body 11. Is set to

That is, as shown in FIGS. 3 and 4, even when the lid 12 is mounted on the upper opening of the container main body 11 in either direction, the outer peripheral side edges of the protruding portions 16 and 17 are fixed to the container main body 11. The lid 12 can be held at a predetermined position with respect to the container main body 11 because the lid 12 is engaged with the inner peripheral edge of the upper opening.

As shown in FIG. 5, when a plurality of cold storage containers 10 are stacked, the inner peripheral side edges of the protruding portions 16 and 17 are provided regardless of whether the lower lid 12 faces in either direction. Is engaged with the outer peripheral edge of the bottom of the container body 11, so that the upper and lower refrigerating containers 10 can be held at predetermined positions.

Therefore, by stacking the cold storage containers 10 attached to the container body 11 by turning over the lid 12 and storing them in the refrigerated warehouse, a large number of cold storage containers are effectively used by utilizing the floor surface in the refrigerator. The contents in 10 can be cooled. In addition, since the containers can be stacked in a stable state, the cold storage containers 10 can be taken in and out of the refrigerated warehouse and can be easily moved in the refrigerator. In particular, the container body 11
The flat area of the cold storage container 10 does not change when the container is sealed and when the contents are cooled by forming the vent 15,
Transport, storage, and cooling can be performed with one transport pallet.

The concave portion 13 and the convex portion 14 formed on the mating surface of the container body 11 and the lid 12 can be provided on four sides of the cold storage container 10, respectively. The unit 14 may be provided. Also,
The protrusions 16 and 17 do not need to be provided continuously, and can be provided in any position and in any shape as long as sufficient holding properties are obtained. For example, they can be provided only at four corners.

[0015]

As described above, according to the insulated container of the present invention, since the air vent which becomes the passage of the cool air can be formed only by inverting the lid, the contents can be cooled with the lid attached. can do. In addition, since the sheets can be stacked in a stable state even when the lid is inverted, the contents can be easily and efficiently cooled in the refrigerated warehouse.
