Description

Technical Field

[0001] The utility model relates to the field of plastic products, in particular to a portable heat-insulating lunch box. Background Art

[0002] With the rise of the food delivery industry and the accelerated pace of life, disposable lunch boxes have become an indispensable part of daily life. It typically takes 20 to 60 minutes for food to be delivered from the store to the customer by a delivery driver. Furthermore, an increasing number of office buildings and residential complexes prohibit delivery drivers from entering. Forcing drivers to wait at the entrance or place the food in a delivery locker until the customer arrives, this significantly increases the actual delivery time.

[0003] Traditional disposable lunch boxes have poor insulation. As delivery times lengthen, the food naturally cools to a lower temperature by the time customers receive it, diminishing the dining experience. Furthermore, bulk orders make stacking difficult, resulting in cold food by the time customers pick it up. Furthermore, delivery drivers can easily shake the food during delivery, disrupting the presentation and even causing food to leak. Therefore, a new disposable lunch box is needed that not only maintains heat but is also convenient for bulk delivery. Utility Model Content

[0004] Based on this, the utility model provides a portable insulated lunch box, which utilizes a bottom box with a liquid storage area and a dinner plate that can be placed in the bottom box, so that the food can be continuously heated and kept warm during the delivery process. It is also provided with handles and socket structures that can be connected to each other, which facilitates the stacking of multiple lunch boxes. It not only has an insulation function, but is also convenient for bulk carrying.
