Description

A thermal insulation box with a stackable structure {THERMAL INSULATION BOX WITH STACKABLE STRUCTURE}

The present invention relates to a hot and cold insulating box having a stackable structure that allows multi-stage stacking of a plurality of hot and cold boxes regardless of the up and down inversion of the box cover.

As the demand for refrigerated or frozen products increases in online shopping malls or offline shopping malls that require delivery, the delivery of products through insulated packaging boxes is increasing significantly. At this time, in the case of a logistics system that allows recovery of insulated packaging boxes, consumer demands for delivery of refrigerated or frozen products can be satisfied by using insulated packaging boxes made of highly functional materials, that is, materials with excellent insulation performance.

However, in the delivery logistics system, which accounts for the majority of online shopping logistics, the recovery of insulated packaging boxes was not possible, and insulated packaging boxes made of materials with excellent insulation performance could not be used due to cost issues. It was common to use an insulated cold box as disclosed in No. 20-0407206 (Notice dated January 25, 2006).

However, a known thermal insulation box has a structure in which a cover made of an insulating material and the box body are combined to seal the interior. A known thermal insulation box can serve to maintain the inside of the thermal insulation box at a low temperature when the external temperature of the thermal insulation box is higher than the internal temperature, such as in an outdoor environment. However, when products requiring fresh storage must be transported by vehicle for a long time, in a frozen/refrigerated vehicle or in a refrigerated/frozen warehouse environment where products are stored, the outside temperature of the insulated cold box is lower than the inside temperature.

In this case, if an insulated/cold box with products stored inside is placed in a frozen/refrigerated vehicle or warehouse, the insulated/cold box is made of an insulating material, so the products inside the insulated/cold box are not affected by the cold air in the frozen/refrigerated vehicle or warehouse. You almost never receive it. Therefore, conventionally, all products stored in the insulated/cold box must be taken out and stored in a frozen/refrigerated vehicle or warehouse, and when the storage period expires, the products in the frozen/refrigerated vehicle or warehouse must be taken out again and placed in a new insulated/cold box, requiring a lot of time. and manpower were required.

Accordingly, a new type of insulated/cold box has been developed that transports the insulated/cold box with the product stored inside in a frozen/refrigerated vehicle or warehouse, and allows the insulated/cold box to be taken out and used immediately when the storage period expires. It is required.

Meanwhile, when placing an insulated/cold box with products stored inside into a frozen/refrigerated vehicle or warehouse, multiple insulated/cold boxes must be stacked in order to efficiently utilize the insulated/cold box storage space in the frozen/refrigerated vehicle or warehouse. do. However, since products must be stored at low temperatures through cold air in a freezer/refrigerated vehicle or warehouse, there is no choice but to store them with the box cover open. Therefore, in this case, stacking of hot and cold boxes is impossible.

In addition, the existing insulated cold box has not been disclosed that has a structure that can circulate the outside temperature inside in addition to blocking the outside temperature (warming/cold insulating effect). Moreover, the structure of stacking a plurality of hot and cold insulating boxes in this structure is also not disclosed.
