Was there. The casters are convenient to carry while dragging the ground, but the structure is complicated and expensive, and it is easy for the casters to roll when the cool box is placed, and it is necessary to take care not to move. Also, some seats are provided with anti-slip such as rubber so that they can be stably placed, but there is a drawback that even if the cool box is slightly moved, it cannot be moved unless it is lifted. For this reason, for example, when pulling out from the back of the luggage carrier of the automobile to the front side, particularly when the caster is on the front side, it is difficult to pull out due to the frictional resistance between the seat body and the floor. In addition, the actual development Sho 51-956
Some of them have ribs protruding along the bottom of the cool box as in Japanese Patent Publication No. 94, but since the end of the rib does not reach the end of the bottom, even with such a structure, the cool box can be pulled out with the box kept horizontal. It is difficult to pull it out even if it is tilted or tilted.If the cool box is tilted, the bottom edge of the cool box body directly contacts the ground and the frictional resistance increases, and the ribs on the cargo bed of the car damage the carpet etc. There was a fear.

In the above-mentioned conventional cold storage box, if casters are provided, the structure is complicated and easily damaged, and the cost is high. In the structure where a rib is provided at the center of the bottom, the body of the cold-insulating box comes into contact with the ground when dragging, and if the end of the rib is sharp, it will be caught by the carpet or the like and will not be pulled, and the carpet will be damaged.

In view of the above-mentioned drawbacks, an object of the present invention is to make it possible to easily move it on a hard ground or on a carpet when tilting a cold box placed on it, and to scratch the bottom of the cold box body. Is not to attach.

[0005]

In order to solve the above-mentioned problems, the present invention is to provide a protrusion having an inclined portion on the side surface side in the vicinity of the side surface of the bottom portion of the cold insulating box. The protrusion is composed of a rib extending in the lateral direction along the front surface. The protrusion should reach at least the end of the bottom of the cool box. The protrusion is that it extends from the bottom to the side of the cool box. That is, a handshake was provided on the side of the cool box.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, when the cold-insulating box is tilted and pulled out, the sloped portion of the projection extending laterally along the front surface on the bottom of the cold-insulating box body rests on the ground or carpet. Therefore, the frictional resistance when pulling out is small and it can be pulled out with a small force. The bottom of the main body is provided with rib-shaped protrusions having inclined portions on both side surfaces reaching the left and right side surfaces and a handshake on both side surfaces, so that it can be pulled out in any side surface direction.

Further, when the cool box is tilted and pulled out,
Since the end of the protrusion reaches the side, the bottom of the main body does not hit the hard ground even when tilted, it does not damage the bottom of the cool box body, it can be easily pulled out, and even in the case of carpet It can be pulled out without being caught by the inclined part. Even when the cool box is moved with a large tilt, the bottom of the body does not contact the ground, so the cool box body is not damaged. Since the handshake is provided on both sides, the handshake can be grasped and pulled out easily from any direction.
