[0027] Example 1

[0028] Traditional FIBCs (Monthly Intermediate Bulk Containers) have an open top, which is ineffective in preventing rain and dust from entering. During outdoor transportation or open-air storage, harsh weather conditions can cause the goods inside to become damp and contaminated, thus affecting the quality and safety of the goods. Current technology often uses simple coverings such as tarpaulins to temporarily cover the FIBCs, but this method has problems such as poor rain and dust protection, unreliable fixing, and easy wind blowing, failing to provide stable and reliable protection for the FIBCs.

[0029] To solve the above problems, such as Figure 1 and Figure 2 As shown, this embodiment provides a rainproof and dustproof tarpaulin ton bag cover, including a rainproof and dustproof cover body 1. The bottom of the rainproof and dustproof cover body 1 is set with an opening, and a closing component 2 is provided on the opening of the rainproof and dustproof cover body 1. The rainproof and dustproof cover body 1 is used to cover the container belt.

[0030] For reference, the rainproof and dustproof cover 1 is made of PVC knife-coated fabric 11. This material has excellent waterproof and dustproof properties, as well as good abrasion resistance and tear resistance, which can effectively protect the goods inside the bag from harsh weather conditions.

[0031] The overall shape of the cover is designed to fit snugly against the shape of the FIBC (Flexible Intermediate Bulk Container), with an opening at the bottom for easy placement. The internal dimensions of the cover can be designed and manufactured to fit FIBCs of different sizes.

[0032] like Figure 2 As shown, in one possible implementation, the closing assembly 2 includes an elastic band 22 and a connector 21, wherein the elastic band 22 is disposed on the opening of the rainproof and dustproof cover 1 via the connector 21.

[0033] The elastic band 22 is made of high-strength, high-elasticity material to ensure that the cover fits tightly against the side wall of the container bag, preventing the intrusion of rainwater and dust. The width and length of the elastic band 22 are designed according to the size of the bottom opening of the cover.

[0034] For reference, the connector 21 can be a stitching thread that securely sews the elastic band 22 to the edge of the cover opening. The choice of stitching thread should take into account its strength and abrasion resistance to ensure reliability for long-term use. The elastic band 22 is evenly sewn to the edge of the cover opening by the stitching thread, forming a tight closure. During the sewing process, ensure that the elastic band 22 remains flat and under uniform tension so that when the cover is placed over the FIBC, the opening can be tightened and secured to the side wall of the FIBC.

[0035] In this embodiment, firstly, the opening of the rainproof and dustproof cover 1 is pulled open and aligned with the top of the container bag (ton bag). The rainproof and dustproof cover 1 is then placed on the container bag. The cover 1 is then loosened, and the elastic band 22 in the closing assembly 2, with its high elasticity and strength, tightly seals the opening of the cover against the side wall of the container bag. The elastic band 22 is securely fixed to the edge of the cover opening by connectors 21 (such as stitching), forming a tight seal. This ensures that even in severe weather conditions, such as strong winds or heavy rain, the cover remains stable and is not easily blown away or loosened. Because the cover is made of PVC scraped fabric 11, it has excellent waterproof and dustproof properties, as well as high abrasion resistance and tear resistance, effectively resisting rain and dust. Furthermore, the tight fit of the elastic band 22 further enhances the protective effect, ensuring the safety and dryness of the goods inside the bag.

[0036] Example 2

[0037] Based on Example 1, such as Figure 3 As shown, the top of the rainproof and dustproof cover 1 is provided with a handle, and there are four handles, which are respectively located at the four corners of the top of the rainproof and dustproof cover 1.

[0038] The handle is secured to the top of the cover by stitching or other reliable connection methods. In this embodiment, high-strength thread is preferably used to firmly sew the handle to the four corners of the top of the cover. During the sewing process, ensure that the thread remains flat and under uniform tension to ensure the handle's sturdiness and durability.

[0039] The handle design allows users to easily grasp and lift the cover when it needs to be removed, avoiding damage or inconvenience caused by directly pulling on the edges of the cover. This design greatly improves the convenience and efficiency of cover removal.

[0040] Example 3

[0041] Based on Example 1, considering the storage requirements of FIBCs (ton bags), direct sunlight should be avoided, as ultraviolet rays and high temperatures in sunlight can damage the material of the FIBCs and accelerate their aging. Rain should also be avoided, as rain can cause the goods inside the FIBCs to become damp, moldy, and corroded. Additionally, the FIBCs should be heat-resistant and fireproof.

[0042] To solve the above problems, such as Figure 4 As shown, in one possible implementation, the rainproof and dustproof cover 1 includes, from the outside to the inside, a PVC scraped cloth 11, a flame-retardant layer 12, a UV-resistant layer 13, a light-shielding layer 14, and a waterproof layer 15, which are sequentially bonded together.

[0043] For reference, the flame-retardant layer 12 is a flame-retardant polyester fiber cloth layer, the UV-protective layer 13 is acrylic fiber, the light-blocking layer 14 is black light-blocking cloth, and the waterproof layer 15 is made of polyethylene.

[0044] Before bonding each layer, the acrylic fibers can be impregnated with a UV-protective finishing agent. This agent typically contains chemicals that absorb or reflect ultraviolet (UV) radiation, such as titanium dioxide (TiO2) microparticles. By immersing the acrylic fibers in this finishing agent and then properly drying them, the UV-protective components in the agent can firmly adhere to the fiber surface or penetrate into the fiber interior, thereby enhancing the fiber's UV protection properties.

[0045] It should be noted that the PVC blade-coated fabric 11, as the outermost layer, possesses excellent waterproof and dustproof properties, while also exhibiting high abrasion resistance and tear resistance. The flame-retardant layer 12 is made of flame-retardant polyester fiber cloth, a material with good flame-retardant properties that maintains structural stability under high-temperature environments, effectively preventing fires. The flame-retardant layer 12 provides additional safety protection when facing high temperatures or fire sources. The UV-protective layer 13 is made of acrylic fiber, which has excellent absorption and reflection properties for ultraviolet rays, effectively reducing the damage of ultraviolet rays to the FIBC material and its internal goods. The light-blocking layer 14 uses black light-blocking fabric to block light transmission and prevent direct sunlight from affecting the goods inside the FIBC. The waterproof layer 15 is made of polyethylene, a material with excellent waterproof properties, ensuring the inside of the cover remains dry. Even in environments with high humidity or when exposed to rain, the waterproof layer 15 effectively prevents moisture from penetrating the inside of the cover.

[0046] The layers, arranged sequentially from the outside in, include PVC coated fabric 11, a flame-retardant layer 12, a UV-resistant layer 13, a light-blocking layer 14, and a waterproof layer 15. This arrangement fully leverages the performance advantages of each material, achieving comprehensive protection for the bulk bags (ton bags). This design not only enhances the durability and safety of the protective device but also ensures the quality and stability of the goods inside.

[0047] In summary, in this embodiment, the rainproof and dustproof cover 1 is designed to fully consider the storage needs of FIBCs (monocell bags). Through the combination of multiple layers, it achieves comprehensive protection for the FIBCs. Specifically, the cover, from the outside to the inside, includes a PVC knife-coated fabric 11, a flame-retardant layer 12, a UV-resistant layer 13 (acrylic material treated with a UV-resistant finishing agent), a light-blocking layer 14, and a waterproof layer 15. These layers are tightly bonded together to form a complete and tight protective system. When the cover is placed over the FIBC, it effectively blocks external factors such as sunlight, rain, and dust from damaging the FIBC and its contents.

[0048] The PVC blade-coated fabric 11, flame-retardant layer 12, UV-resistant layer 13, light-shielding layer 14, and waterproof layer 15, arranged sequentially from the outside to the inside, fully utilize the performance advantages of each layer to achieve comprehensive protection for the FIBC (Flexible Intermediate Bulk Container). This design not only improves the durability and safety of the protective device but also ensures the quality and stability of the internal cargo. The UV-resistant layer 13 is further enhanced by treating the acrylic fibers with a UV-resistant finishing agent. This helps reduce the damage of ultraviolet rays to the FIBC material and its internal cargo, extending the service life of the FIBC and the shelf life of the cargo. The flame-retardant layer 12 provides additional safety when facing high temperatures or fire sources. This helps prevent fire accidents and protects the FIBC and its internal cargo. The outer layer of the PVC blade-coated fabric 11 has excellent abrasion resistance and tear resistance, resisting external physical damage. At the same time, its smooth surface and easy-to-clean characteristics make maintenance and cleaning of the cover simpler and more convenient.

[0049] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
