Portable sealed storage box for logistics transportation

Abstract

The invention discloses a portable sealed storage box for logistics transportation. The storage box is easy and convenient to operate, air in a box body is discharged by pressing a sealing cover, andexpansion of an elastic spacer cooperates with attachment of wall box walls for sealing. The storage box is characterized in that the top of the box body is provided with an opening, the sealing coveris placed in the box body, one end of an air inlet pipe is arranged on the sealing cover, an air inlet one-way valve is embedded in the sealing cover and corresponds to the air inlet pipe, the air inlet pipe communicates with the air inlet end of the air inlet one-way valve through a plurality of air holes, the air outlet end of the air inlet one-way valve communicates with the interior of the box body, one end of an air outlet pipe is arranged on the sealing cover, an air outlet one-way valve is embedded in the sealing cover and corresponds to the air outlet pipe, and the air outlet pipe communicates with the air outlet end of the air inlet one-way valve through a plurality of air holes.

Description

technical field [0001] The invention relates to a portable sealed storage box for logistics transportation, which relates to a storage box used for logistics transportation and belongs to the field of logistics equipment. In particular, it relates to a sealed storage box which is simple and convenient to operate, and the gas in the box is discharged by pressing down the sealing cover, and is sealed in cooperation with the expansion of the elastic partition and the bonding of the box wall. Background technique [0002] In the process of logistics transportation, especially in the process of long-distance freight transportation, in order to ensure the freshness of agricultural products and avoid their deterioration during transportation, it is usually necessary to seal the agricultural products.

[0002] In the process of logistics transportation, especially in the process of long-distance freight transportation, in order to ensure the freshness of agricultural products and avoid their deterioration during transportation, it is usually necessary to seal the agricultural products. The traditional logistics sealing packaging method is usually to put agricultural products into bags Finally, the air in the bag is evacuated by an additional vacuum pump to achieve the effect of sealed packaging, but this sealing method is cumbersome to operate, and it takes a long time to seal and prepare one by one, which does not meet the needs of modern fast and fast logistics turnover. However, the currently used product sealing box is only sealed by closing the box body when sealing, and the air remaining in the box cannot be discharged during sealing, resulting in that the products inside the box body are still prone to deterioration even though they are sealed and isolated

[0003] The notification number CN110040362A discloses a protection box and its logistics protection box, including an outer box, an inner box, a protective layer, and a box cover. An inner cavity is installed inside the outer box, and a box body gap is formed between the inner side of the outer box and the inner box ;The protective layer is set on the inner side of the inner box, which is used for direct contact with the consigned items. The inner side of the protective layer is provided with a placement cavity, which is used to place the goods that need to be consigned; The box and the outer box are assembled and fixed. The top fixing ring seals the top of the box body gap. The top of the outer box is provided with a card slot for the outer box. The outer box and the inner box are welded and fixed. The protective box only seals the box cover on the box mouth, and cannot effectively discharge the air retained in the box.
