Heat-insulating packing case and method for manufacturing same

Abstract

The invention discloses a heat-insulating packing case in which a built-in box and a heat-insulating box are combined, and aims to overcome the defects that in the prior art, the heat-insulating packing case which is subjected to pretreatment in the opening way is low in the pretreatment efficiency and has a poor heat insulation effect during transportation or storage due to a limit on planes in which the openings can be formed. The heat-insulating packing case comprises a case body, a case cover on which a fixing groove and a sealing ring are integrated, locks, the built-in box and a thermograph, wherein each of the case body and the case cover is made of three layers of materials, namely an outer shell layer, a heat-insulating layer and a liner layer; the fixing groove is formed in the connecting part of the liner layer of the case cover and the case body; the sealing ring is arranged in the fixing groove; when the case cover covers the case body, the case body is stabilized and sealed through the locks; the built-in box adopts a mesh structure, and the size of the built-in box is matched with that of the liner layer of the heat-insulating packing case; an observation window is arranged on the case body or the case cover; the thermograph is arranged in the observation window for observing temperature in the packing case.

Description

[0001] Technical field [0001] The present invention belongs to packaging boxes in the field of machinery and electronics, particularly packaging boxes with thermal insulation function and its manufacturing method. Background technique [0002] Most of the existing packaging boxes adopt the structure of combining the box body and the box cover with a mechanical structure, and the gap is relatively large. Some packaging boxes are equipped with a sealing ring to play a certain role in sealing, but they do not have heat insulation performance. Although it has a certain heat insulation performance, it is pretreated by opening holes. Since the opening surface and the outer packaging are a structure, only a small number of holes can be opened for the strength and heat insulation of the structure, resulting in poor pretreatment efficiency.

Problems solved by technology

[0002] Most of the existing packaging boxes adopt the structure of combining the box body and the box cover with a mechanical structure, and the gap is relatively large. Some packaging boxes are equipped with a sealing ring to play a certain role in sealing, but they do not have heat insulation performance. Although it has a certain heat insulation performance, it is pretreated by opening holes. Since the opening surface and the outer packaging are a structure, only a small number of holes can be opened for the strength and heat insulation of the structure, resulting in poor pretreatment efficiency. Excessive openings lead to weakened structural strength, and poor heat insulation during transportation or storage; there are many pretreatment methods, such as cleaning, anti-corrosion, freezing, heating, disinfection, weighing, drying, quality inspection and Quantity, etc., the opening method cannot support multiple pretreatment methods. At the same time, direct pretreatment with packaging boxes will also affect the efficiency of turnover and use, which cannot meet the development needs of modern logistics.
