Nitrogen-filled fresh-keeping box for storage and transportation of pickled food

Abstract

The invention relates to the technical field of fresh-keeping boxes, and discloses a nitrogen-filled fresh-keeping box for storage and transportation of pickled food. The nitrogen-filled fresh-keeping box comprises a box body and a sealing cover, wherein first through grooves are formed in the periphery of the box body, a first accommodating groove is formed in the groove bottom of the first through groove, a side airbag is arranged at the groove bottom of the first accommodating groove, a first connecting part is arranged on one side of the side airbag, the first connecting part is slidably connected into the first through groove, and a first pressurizing protection device is arranged on the box body and used for extruding the side airbag, so that the size of the side airbag is increased, the first connecting part is pushed to extend out to protect the periphery of the box body, and impact on the whole fresh-keeping box is reduced.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping boxes, in particular to a nitrogen-filled fresh-keeping box used for storage and transportation of pickles. Background technique [0002] Fresh-keeping boxes are often used in the storage and transportation of pickled vegetables (such as pickled mustard, pickled beans, etc.). Food-grade plastics form hot-pressed films, which can be divided into nitrogen-filled and non-nitrogen-filled crisper products. The nitrogen-filled fresh-keeping box is to extract all the air in the packaging container and seal it to maintain a high pressure inside the bag. The scarcity of air is equivalent to hypoxia, so that microorganisms have no living conditions, so as to achieve the purpose of extending the shelf life of pickled food. [0003] In view of the above-mentioned related technologies, the inventors of the present application found at least the following technical problems in the process of realizing the...

AI Technical Summary

Problems solved by technology

[0004] The embodiment of the present application provides a nitrogen-filled fresh-keeping box for the storage and transportation of pickled vegetables, which solves the problem that in the prior art, the fresh-keeping boxes are prone to collide with each other during transportation, which causes the structure of the fresh-keeping box to be unstable, and thus makes the inside of the fresh-keeping box The problem of poor sealing effect realizes the buffer protection of the fresh-keeping box, reduces the impact on the fresh-keeping box, and makes the fresh-keeping box maintain a stable structure
