Description

Technical Field

[0001] This utility model relates to the field of leak-proof container bags, and in particular to an external barrier leak-proof container bag. Background Technology

[0002] FIBCs, also known as flexible container bags, ton bags, or space bags, are a type of unitized transport equipment. When used with cranes or forklifts, they enable unitized transport of bulk, loose, or granular materials. FIBCs are flexible transport packaging containers widely used for transporting powdery, granular, or lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals.

[0003] However, traditional FIBCs (Flexible Intermediate Bulk Containers) have many problems. On the one hand, their barrier properties are limited, allowing moisture and air to easily penetrate the bag, causing the material to become damp, oxidize, and deteriorate, affecting its quality. On the other hand, their leak-proof performance is poor. During transportation and handling, materials can easily leak from the seams and openings of the FIBC due to collisions and compression, resulting not only in material loss but also in environmental pollution.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model discloses an external barrier leak-proof container bag, comprising a bag body 1, a storage structure 2, a sealing structure 4, and a protective structure 6. The bag body 1 is divided into an outer bag 5 and an inner bag 7. The outer bag 5 is made of polypropylene and has a wear-resistant coating on its surface. Reinforcing plates 501 are provided at the four corners of the outer bag 5 to prevent damage caused by excessive force on the corners of the container bag. The reinforcing plates 501 are made of plastic and have an anti-slip texture on their surface. When the container bags are stacked, the anti-slip texture increases the friction. To prevent slippage between the containers and ensure storage and transportation safety, the reinforcing plate 501 and the outer bag 5 are connected by hot-melt welding. The outer surface of the outer bag 5 is provided with reflective stripes 502, which can improve the visibility of the container bag during nighttime operations and ensure operational safety. The inner bag 7 is made of high-strength plastic film. The outer bag 5 is on the outermost side of the bag body 1, and the inner bag 7 is on the innermost side of the bag body 1.

The inflation port 603 passes through the sealing strip 602, and the connection between the inflation port 603 and the sealing strip 602 is achieved by hot-melt welding.

[0030] The above structure allows air to be inflated into the air bag 601 through the air inlet 603, causing the air bag 601 to expand under the action of air, thus protecting the inner bag 7 and the materials inside. The sealing strip 602 ensures that debris falls into the interior of the bag body 1, preventing damage to the air bag 601.

[0031] Working principle: First, the material is loaded into the bag body 1. Then, the sealing gasket 404 is embedded into the sealing opening 403 for the first seal. Next, the hook side 401 of the Velcro strap is attached to the rough side 402 of the Velcro strap for the second seal. After sealing, the air bag 601 is inflated through the air inlet 603, causing the air bag 601 to expand under the action of air, thus protecting the inner bag 7 and the material inside. The sealing strip 602 ensures that debris falls into the interior of the bag body 1, preventing damage to the air bag 601. When folding for storage, the storage base 201 can be folded through the hinge 204 and fixed by the hook 202 and buckle 203.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
