Description

Technical Field

[0001] This utility model relates to the field of container bag technology, and more specifically, to a container bag that is easy to open. 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, granular, or powdery materials. FIBCs are flexible transport packaging containers widely used for transporting powdery, granular, or lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals. Developed countries commonly use FIBCs for transportation and warehousing. The use of FIBCs in my country is expanding, therefore, the market demand for FIBC products has great potential and a very broad development prospect.

[0003] When unloading existing FIBCs, workers need to first align the discharge bag with the corresponding powder receiving container from below, and then untie the closing rope on the discharge bag to unload the material. This operation is cumbersome and the unloading efficiency needs to be improved. Utility Model Content

[0027] Example 1

[0028] like Figure 1-4 As shown, this embodiment provides a container bag that is easy to open, including a bag body with an inlet 4. The bag body includes an outer bag 1, a first inner bag 2, and a second inner bag 3. The first inner bag 2 and the second inner bag 3 are disposed inside the outer bag 1. The bottom of the outer bag 1 is provided with an outlet 5, and a sealing element is detachably connected to the outlet 5. The bottom of the second inner bag 3 is provided with a sealing film 6, and an easy-tear line 7 is provided at the connection between the sealing film 6 and the second inner bag 3. A support plate 8 is provided between the inner bottom surface of the first inner bag 2 and the outer bottom surface of the second inner bag 3.

[0029] The outer bag 1, the first inner bag 2, and the second inner bag 3 work together to enhance the bag's loading capacity and prevent tearing. The discharge port 5, the seal, and the sealing film 6 work together to allow the first inner bag 2 to be cut or punctured at the discharge port with a sharp object, allowing material to flow from the discharge port 5 into the hopper and preventing spillage during handling. The support plate 8 increases the bag's strength, enhancing its safety during lifting, and also guides the material during discharge, improving discharge speed and efficiency.

[0030] In a specific embodiment of this invention, the sealing element includes a sealing base fabric 14, with a zipper 15 on its outer periphery, and a chain 9 adapted to the zipper 15 at the discharge port 5. During transportation, the sealing base fabric 14 is connected to the outer bag 1 via the zipper 15 and the chain 9, thereby improving the sealing performance of the container bag and enhancing its packaging effect on the materials. During discharge, the sealing base fabric 14 is removed from the outer bag 1, and then the container bag is hoisted. A sharp object is used to puncture the first inner bag 2 at the discharge port 5, enabling rapid material discharge and preventing premature opening and spillage.

[0031] In this specific embodiment, the support plate 8 includes multiple support plates 81. Adjacent support plates 81 are connected by flexible strips 82. One end of each support plate 81 is close to the tear line 7, and the other end of each support plate 81 abuts against the bottom edge of the first inner bag 2. When the first inner bag 2 is torn, the bag body at the opening droops due to the gravity of the material. The multiple support plates 81 can support the opening, forming multiple smooth, inclined discharge surfaces at the opening, thereby increasing the material discharge speed. The multiple support plates 81 are connected to form a support plate 8 with a central opening.

[0032] In a specific embodiment of this invention, the support plate 81 is glued to both the first inner bag 2 and the second inner bag 3. Gluing enhances the connection strength between the support plate 81 and the first inner bag 2 and the second inner bag 3.

[0033] In this specific embodiment, the outer bag at the feed inlet 4 is equipped with a drawstring 11, and a storage space is provided between the first inner bag 2 and the second inner bag 3 at the feed inlet 4. A moisture-proof component 10 is installed within the storage space. The moisture-proof component 10 absorbs and dries the humid air entering the bag through the feed inlet 4, improving the moisture-proof effect at the bag opening and greatly reducing the risk of moisture damage to transported materials. The moisture-proof component 10 and the drawstring 11 work together to enhance the safety of the materials inside the bag.

[0034] In this specific embodiment, the outer bag 1 is a woven fabric, and the first inner bag 2 and the second inner bag 3 are polyethylene films. The woven fabric has relatively low extensibility but good support, effectively supporting the first inner bag 2 and the second inner bag 3 and preventing the inner bags from being punctured by high-density materials. The polyethylene film has good barrier properties, preventing the materials from getting damp.

[0035] In a specific embodiment of this invention, the outer circumference of the outer bag 1 is provided with lifting straps 12. Multiple lifting straps 12 are provided, which facilitate the lifting of the container bag while also providing good strength to prevent breakage during lifting.

[0036] In a specific embodiment of this invention, a reinforcing strap 13 is provided on the outer bag 1, and the reinforcing strap 13 is arranged along the circumferential direction of the outer bag 1. The reinforcing strap 13 can improve the load-bearing capacity of the bag.

[0037] In use, materials are loaded into the container bag through the inlet 4, and the inlet 4 is sealed with the closing rope 11 to complete the packaging of the materials. When discharging, the seal is removed from the outlet, and the container bag is hoisted to the hopper by the hoisting equipment holding the lifting strap 12. The bottom of the first inner bag 2 at the outlet 5 is cut open using the opening part at the hopper, and the material is discharged along the inclined direction of the support plate 81, realizing the rapid opening and unloading of the container bag.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
