Fruit and vegetable fresh-keeping packing box and fresh keeping method thereof

Abstract

The invention relates to a fruit and vegetable fresh-keeping packing box and a fresh keeping method thereof. The packing box comprises a box body, a sealing set, a box cover, four buckle handles, andan air extracting device; the sealing set is wrapped on the box body; the box cover is arranged above the box body; the four buckle handles are arranged around the box cover; and the air extracting device is mounted at the front end of the box body. The packing box can solve the difficulties, such as reduction of the sealing effect due to deformation of a traditional sealing strip after long-timeuse due to sealing of the box cover and the box body by the sealing strip in a groove of the box cover and a traditional fresh keeping box consisting of the box cover and the box body, difficult cleaning of the sealing strip due to positioning in the groove, easy breeding of mould after long-time use, reduction of the sealing effect due to placement back of the sealing strip after taking out for cleaning, need of a special air pump to extract air from some frame-vacuumized fresh keeping boxes, and inconvenient and more complex carrying of the air pump.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping boxes, in particular to a fruit and vegetable fresh-keeping packaging box and a fresh-keeping method thereof. Background technique [0002] Fruits and vegetables are rich in minerals, vitamins, fibers, and have high nutritional value and use value. Therefore, they have become a necessity in daily life. In order to improve the freshness of fruits and vegetables, people often put them in fresh-keeping boxes However, ordinary fresh-keeping boxes often have some defects: [0003] 1. The current fresh-keeping box is composed of a box cover and a box body. There is a sealing strip in the groove of the box cover to seal the box cover and the box body. However, the existing sealing strip will be deformed after long-term use, thereby reducing the The sealing effect, and because the sealing strip is located in the groove, it is difficult to clean when cleaning in the groove, and it is easy to breed m...

AI Technical Summary

Problems solved by technology

[0006] The present invention can solve the problem that the current fresh-keeping box is composed of a box cover and a box body, and a sealing strip is provided in the groove of the box cover to seal the box cover and the box body. However, the existing sealing strips will deform after long-term use and thus The sealing effect is reduced, and because the sealing strip is located in the groove, it is difficult to clean it when cleaning in the groove, and it is easy to breed mold in the long run. Taking it out and cleaning it and putting it back will reduce the sealing effect. Some can vacuum the inside of the frame The fresh-keeping box requires a special air pump to pump air, but the air pump is inconvenient to carry and is relatively cumbersome.
