Embodiment Construction

[0007] Such as figure 1 : When keeping items fresh, first put the items into the large plastic bag A from the long side opening C of the equilateral trapezoidal small plastic bag through the short side opening. If more air is brought in, use a vacuum cleaner to suck out the air, and then use a small The nitrogen gas generated by the nitrogen generator is directly filled into the large plastic bag at the opening C of the long side of the small plastic bag. Because the structure of the permanent fresh-keeping bag can only enter the gas, the permanent fresh-keeping bag will soon be full due to The gas will bulge up, so that the articles can be kept fresh for a long time, and the articles can be protected from being damaged due to extrusion and collision during transportation. Finally, the sealed zipper C at the long side opening of the equilateral trapezoidal small plastic bag is pulled to play a role. The role of double sealing. If the purity requirements of the anti-corrosion ...

Abstract

The invention aims to preserve objects conveniently at low cost for a long time. A permanent preservation bag is characterized in that a small plastic bag in antiparallelogram is sealed in a big plastic bag; the long side of the small plastic bag in antiparallelogram is sealed at the edge of the big plastic bag; and the short side of the small plastic bag in antiparallelogram is placed in the big plastic bag. The long side and short side of the small plastic bag in antiparallelogram are open and communicated and used as a sole passage for taking objects from the preservation bag and inflating the anti-corrosive gas. A sealing zipper is arranged at the opening of the long side of the small plastic bag in antiparallelogram and has double-seal function.

Description

Technical field: [0001] The invention relates to a reusable fresh-keeping bag which can keep fresh items for a long time, is very convenient for filling anti-corrosion gas and picking and placing items. Background technique: [0002] At present, long-term fresh-keeping items are generally vacuum-packed or sealed in bags with anti-corrosion gas and items, so that the packaging bags can only be used once, and industrial equipment is needed for packaging, so individuals do not have these conditions at all. Time preservation items. Invention content: [0003] Technical problem: The purpose of this invention is to make it very convenient for farmers or individuals to keep fresh and pick and place items anytime and anywhere, and because the fresh-keeping bags can be reused for a long time and the fresh-keeping time is long, the cost of fresh-keeping is very low. [0004] Technical solution: The present invention seals a small equilateral trapezoidal plastic bag in a large plast...
