Flexible freight bag with deforming-prevention inner bag

Abstract

The invention discloses a flexible freight bag with a deforming-prevention inner bag. The bag comprises a bag body and the inner bag, cover plates are arranged on two symmetric outer side walls of thebag body, reinforcing layers are arranged on the connecting positions of any two side walls of the upper end of the bag body, a lifting belt is mounted between each reinforcing layer and the bag body, and multiple observing openings are symmetrically formed in the outer side wall of the bag body. The bag is novel in structure, an overpressure warning device is mounted on the outer side of the inner bag, when the pressure borne by the inner bag exceeds index value, a worker can be warned in time, reinforcing belt and tiepiece sheet structures are added, deforming of the flexible freight bag during filling and transport can be effectively prevented, and the bearing capacity of the flexible freight bag can be improved.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a container bag with an anti-deformation inner bag. Background technique [0002] Container bags, also known as flexible container bags, ton bags, space bags, etc., are large-volume transport bags made of foldable rubberized cloth, resin processed cloth and other soft materials. Using this kind of packaging, not only It is conducive to improving the loading and unloading efficiency, and is especially suitable for the packaging of bulk powder and granular goods, which is conducive to promoting the standardization and serialization of bulk goods packaging and reducing transportation costs. [0003] Existing container bags are mostly produced in a square structure in order to be stacked neatly after filling, but even if the bottom surface of the container bag is made into a square structure, it is difficult to ensure that the shape of the container bag remains after it is fil...

AI Technical Summary

Problems solved by technology

[0003] Existing container bags are mostly produced in a square structure in order to be stacked neatly after filling, but even if the bottom surface of the container bag is made into a square structure, it is difficult to ensure that the shape of the container bag remains after it is filled with materials This is not only not conducive to stacking and storage, but also inconvenient for machine lifting and transportation, resulting in the problem of inconvenient use of container bags. Therefore, we propose a container bag with an anti-deformation inner bag
