The handle 29 does not protrude from the outer wall of the cool box main body 1 and the cool boxes can be brought as close as possible. In addition, since the handle 29 is provided in the concave portion 28 formed in the portion where the reinforcing projection 27 is not formed, the space between the cold store and the adjacent cool store can be increased, so that when the cool store is moved. Thus, it is possible to more reliably prevent an accident in which the hand H holding the grip 29 is pinched.

Second Embodiment FIGS. 5 to 7 show the essential parts of a cool box according to a second embodiment of the present invention.

In this case, the concave portion 28 is formed from the front surface to the side surface of the door 2 serving as the front surface of the cool box main body 1, and the handle 29 is supported by the side surface portion of the concave portion 28. Parts 29a, 29a and the supporting part 29
a, 29b, which are bent substantially at a right angle from each other and extend to a position separated from the side surface of the cool box main body 1 by a predetermined distance in the concave portion 28. The other configuration and operation and effect are the same as those in the first embodiment, and thus the description is omitted.

Third Embodiment FIG. 8 shows a main part of a cool box according to a third embodiment of the present invention.

In this case, the outer surface of the reinforcing projection 27 is covered with a shock absorbing cushioning material 30. In this way, the shock force when the cold storages collide with each other can be absorbed by the cushioning material 30, and the distance between the cold storages and the adjacent cold storage can be increased, and the grip 29 can be gripped. It is possible to more reliably prevent an accident in which a hand is pinched between an adjacent cool box. The other configuration and operation and effect are the same as those in the first embodiment, and thus the description is omitted.

Fourth Embodiment FIG. 9 shows a main part of a cool box according to a fourth embodiment of the present invention.

In this case, the recesses 28 provided on both sides of the reinforcing projection 27 are provided with lateral handles 29. In this case, the handle 29 is gripped by hand from above, so that the hand gripping the handle 29 does not protrude from the side surface of the cool box main body 1 and the hand is held between the cool box and the adjacent cool box. Will not be interposed.
