Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a buckle-sealed foam box. Background Art

[0002] With the national policy requirements for rural revitalization, express delivery companies are also constantly developing cold chain packaging products. Cold chain packaging has gradually become a key development direction for express delivery companies. Currently, common cold chain packaging boxes on the market include EPS, EPP, XPS, etc. Among them, EPS foam boxes have good cold preservation and shockproof effects, and are widely used in the delivery packaging boxes of fresh cold chain products due to their low price.

[0003] The EPS foam boxes currently used usually adopt the structure of upper and lower lids, and in the actual production process, in order to facilitate closing the lid, there is a certain gap at the interface between the upper lid and the box body. However, in the actual transportation process, fresh products leak during delivery, which is specifically manifested as fresh fruits rotting and leaking water, or fresh fruits (such as lychees) are immediately put into the foam box after being put into ice water, resulting in water in the foam box, etc. However, in the actual transportation process, it is impossible to ensure that the foam box is placed with the opening facing up. During transportation, there is a situation where mail is inverted, and water will flow out of the foam box, further causing the outer foam box to be wet or contaminating other mails, etc. Therefore, it is necessary to develop a foam box with good sealing performance.
