Description

[0001] This application is a divisional application of the patent application with the application date of February 25, 2021, the application number of 202110215423.5, and the invention title of "An Exhaust Heat-insulating and Splash-proof Food Box and Ventilation Component". Technical Field

[0002] The present invention belongs to the field of food packaging equipment, and particularly relates to an exhaust heat-insulating and splash-proof food box and a ventilation component. Background Art

[0003] With the increasing acceleration of the social rhythm, the dining methods of the younger generation have entered a fast mode, and various problems caused by takeaway food delivery and taking food out are increasingly taken seriously. First of all, when takeaway food is transported, it is inevitable that the soup will spill during the bumpy journey, making the surface of the food box dirty. At the same time, after fried and pan-fried foods are packed, due to the poor air permeability of disposable lunch boxes, the lunch box will be filled with water vapor emitted by the food after a period of time, resulting in the fried and pan-fried foods losing their crispness and being unable to maintain their original flavor, and most packed food boxes do not have the function of heat preservation. Secondly, among the takeout lunch boxes used at home, most are sealed lunch boxes. Although this can ensure that the soup does not spill, the deterioration of the taste of the food caused by the sealing has become a new problem.

[0004] In view of the above reasons, the present invention provides an exhaust heat-insulating and splash-proof food box and a ventilation component to solve the problems existing in the prior art. Summary of the Invention

The box cover a is hermetically joined to the box body b. An air vent part a1 is provided on the box cover a, and a breathable heat-insulating and water-absorbing material is provided in the air vent part a1. The air vent part a1 includes an air vent outer shell a2, and the breathable heat-insulating and water-absorbing material is filled in the air vent outer shell a2. Herein, the air vent outer shell a2 is used to fix the breathable heat-insulating and water-absorbing material.

[0025] In this embodiment, the breathable heat-insulating and water-absorbing material includes a nano-porous heat-insulating material, a fiber product or a cotton ball material. Among them, the fiber product includes non-woven fabric made of artificial fiber, silk cotton, etc. The breathable heat-insulating and water-absorbing material can be a single type of material or a composite material composed of multiple materials.

[0026] As Figure 2 shown, to ensure the water absorption effect and the appearance cleanliness of the food box, the breathable heat-insulating and water-absorbing material is arranged in two layers up and down, that is, it includes material a01 and material a02, and there is a gap between the two layers of breathable heat-insulating and water-absorbing material up and down. To further enhance the heat-insulating and exhaust effects, the two layers of breathable heat-insulating and water-absorbing material arranged up and down are dense in the upper layer and sparse in the lower layer or sparse in the upper layer and dense in the lower layer.

[0027] Furthermore, for the easily moldable breathable heat-insulating and water-absorbing material, the whole material is divided into multiple sheets or strips, and the air vent part a1 is formed by arranging the multiple sheets or strips in sequence to achieve a good ventilation effect.
