Description

Technical Field

[0001] This utility model relates to the field of container bag technology, specifically a container bag with a damage-resistant structure. Background Technology

[0002] FIBC (Flexible Intermediate Bulk Container), also known as flexible intermediary bag, ton bag, or space bag, is a type of unitized container that, when used with cranes or forklifts, enables unitized transport of bulk, granular, or powdery materials such as chemical raw materials, fertilizers, grains, and cement. It offers advantages such as large capacity, ease of loading and unloading, and reusability. Developed countries widely use FIBCs for transportation and warehousing, improving logistics efficiency and reducing transportation costs.

[0003] Traditional FIBCs are typically made of materials such as polypropylene. While these materials possess a certain degree of strength and toughness, they are still prone to damage under significant external forces or during prolonged use. For example, during hoisting, the FIBC may experience excessive tension, leading to broken straps or tearing of the bag. Additionally, during storage and transportation, the bag may be damaged by compression, friction, or scratches from sharp objects.

[0004] Therefore, a container bag with a breakage-resistant structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a container bag with a damage-resistant structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a container bag with a damage-resistant structure, comprising a bag body and two lifting straps above it, an outer support fixedly connected to the bottom of the bag body, an inner lining ring fixedly connected to the lower edge of the inner wall of the bag body, a reinforcing layer fixedly connected to the outer side of the bag body, a wear-resistant layer fixedly connected to the outer side of the reinforcing layer, a protective layer fixedly connected to the inner side of the bag body, a bag opening reinforcing seat fixedly connected to the top of the bag body, both lifting straps fixedly connected to the bag opening reinforcing seat, and multiple reinforcing straps fixedly connected to the outer side of the bag opening reinforcing seat and the outer side of the outer support seat.

[0007] Preferably, the reinforcing layer is made of polypropylene, the wear-resistant layer is made of polyester film, the protective layer is made of polyethylene film, and both slings are made of high-strength polyester fiber.

[0008] Preferably, a cushioning pad is fixedly connected inside the bag opening reinforcement seat, and one side of the cushioning pad is fixedly connected to the bag body. The bottoms of the two straps are stitched together with the bag body and the bag opening reinforcement seat through multiple stitches using high-strength thread.

[0009] Preferably, a reinforcing strip is fixedly connected between adjacent groups of reinforcing strips, and multiple grooves are provided on the outer side of each of the multiple reinforcing strips. One side of each of the multiple reinforcing strips is fixedly connected to the outer support, the bag body, and the bag opening reinforcing seat, respectively.

[0010] Preferably, a reinforcing frame is fixedly connected to the lower part of the inner wall of the bag, and the outer side of the reinforcing frame is fixedly connected to the inner lining ring.

[0011] Preferably, an isolation ring is installed at the bottom of the outer support, and a wear-resistant strip is installed at the bottom of the isolation ring. The wear-resistant strip is made of rubber material.

[0012] Preferably, a baffle ring is installed on the top of the bag opening reinforcement seat, and multiple overflow ports for material overflow are opened at the bottom of the baffle ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model strengthens the bottom load-bearing capacity of the FIBC by reinforcing the outer side of the bag body with an inner lining ring and an outer support base. At the same time, the outer wear-resistant layer provides wear resistance and scratch protection, which, together with the middle reinforcement layer, bears the main external force, reducing the possibility of the bag body being damaged when subjected to the weight of the goods, impact force, or scratches from sharp objects. Meanwhile, the inner protective layer prevents chemical reactions between the goods and the bag material, and also plays a certain role in moisture protection, protecting the quality of the goods. In addition, the multiple reinforcing strips between the outer support base and the bag mouth reinforcement base further improve the overall load-bearing capacity and stress distribution ability of the FIBC, and extend the service life of the FIBC.

[0015] This utility model uses multiple stitches to sew the bag body, bag opening reinforcement seat, and straps together. The bag opening reinforcement seat evenly transmits the tensile force to the bag body. The reinforcement layer is made of polypropylene material, which can effectively disperse and bear the tensile force and prevent the bag body from tearing.

[0016] Simultaneously, the reinforcing strips installed between adjacent reinforcing strips and the isolation rings and wear-resistant strips installed at the bottom further connect and reinforce the adjacent reinforcing strips, the outer support, and the bag mouth reinforcement, improving the toughness of the FIBC itself. At the same time, the isolation rings reinforce the stability of the bottom of the FIBC, and the wear-resistant strips prevent the bottom of the FIBC from wearing out. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-3 This utility model provides a technical solution: a container bag with a damage-resistant structure, comprising a bag body 3 and two lifting straps 7 on top of it. An outer support seat 2 is fixedly connected to the bottom of the bag body 3. An inner lining ring 1 is fixedly connected to the lower edge of the inner wall of the bag body 3. A reinforcing layer 31 is fixedly connected to the outer side of the bag body 3, and a wear-resistant layer 32 is fixedly connected to the outer side of the reinforcing layer 31. A protective layer 33 is fixedly connected to the inner side of the bag body 3. A bag opening reinforcement seat 5 is fixedly connected to the top of the bag body 3. Both lifting straps 7 are fixedly connected to the bag opening reinforcement seat 5. Multiple reinforcing straps 4 are fixedly connected to the outer side of the bag opening reinforcement seat 5 and the outer side of the outer support seat 2. The outer side of the bag body 3 is reinforced by the inner lining ring 1 and the outer support seat 2, which strengthens the bottom bearing capacity of the container bag. At the same time, the outer wear-resistant layer 32 provides wear-resistant and scratch-proof protection, which, together with the middle reinforcement layer 31, bears the main external force and reduces the possibility of the bag body being damaged when subjected to the weight of the goods, impact force, or scratches from sharp objects. Meanwhile, the inner protective layer 33 prevents the goods from reacting chemically with the bag body material and also plays a certain role in moisture protection, protecting the quality of the goods. In addition, the multiple reinforcing bands 4 set between the outer support seat 2 and the bag mouth reinforcement seat 5 further improve the overall load-bearing capacity and stress distribution ability of the container bag.

[0023] like Figure 3As shown, the reinforcing layer 31 is made of polypropylene material, specifically modified polypropylene material. This modified PP material is enhanced by adding reinforcing materials such as glass fiber or carbon fiber to improve its strength and toughness. This modified PP material can withstand greater external forces, reducing the possibility of the bag breaking when subjected to the weight and impact of goods. The abrasion-resistant layer 32 is made of polyester film material. PET film has good tensile strength and abrasion resistance, effectively preventing the bag from being rubbed and scratched during transportation and storage. The protective layer 33 is made of polyethylene film material. Both straps 7 are made of high-strength polyester fiber material. The PE film prevents chemical reactions between the goods and the bag material, while also providing some moisture protection, thus protecting the quality of the goods.

[0024] like Figure 1 and 2 As shown, a cushioning pad 6 is fixedly connected inside the bag opening reinforcement seat 5. One side of the cushioning pad 6 is fixedly connected to the bag body 3. The bottom of both lifting straps 7 are stitched together with high-strength thread between the bag body 3 and the bag opening reinforcement seat 5. The lifting straps 7 are made of high-strength polyester fiber material. Both lifting straps 7 are fixedly connected to the bag opening reinforcement seat 5. A cushioning pad 6 is fixedly connected inside the bag opening reinforcement seat 5. One side of the cushioning pad 6 is fixedly connected to the bag body 3. The bottom of the lifting straps 7 is stitched together with high-strength thread between the bag body 3 and the bag opening reinforcement seat 5. During the lifting process, the lifting straps 7 bear the tension. The tension is first applied to the bag opening reinforcement seat 5. Due to the presence of the cushioning pad 6, it can play a buffering role, reducing the impact of the tension on the connection between the bag opening reinforcement seat 5 and the bag body 3. Then, the tension is evenly transferred to the bag body 3 through the bag opening reinforcement seat 5. The reinforcement layer 31 of the bag body 3 can effectively disperse and bear the tension, preventing the bag body from tearing.

[0025] A reinforcing strip 8 is fixedly connected between adjacent sets of reinforcing strips 4. Multiple grooves 9 are provided on the outer side of multiple reinforcing strips 8. One side of multiple reinforcing strips 8 is fixedly connected to the outer support 2, the bag body 3, and the bag mouth reinforcing seat 5 respectively. Multiple reinforcing strips 4 are fixedly connected to the outer side of the bag mouth reinforcing seat 5 and the outer support 2. A reinforcing strip 8 is fixedly connected between adjacent sets of reinforcing strips 4. The setting of these reinforcing strips 4 and reinforcing strips 8 further improves the overall load-bearing capacity and stress distribution capacity of the container bag.

[0026] A reinforcing frame 12 is fixedly connected to the lower part of the inner wall of the bag body 3. The outer side of the reinforcing frame 12 is fixedly connected to the inner lining ring 1. The reinforcing frame 12 further improves the stability of the bottom of the container bag. An isolation ring 13 is installed at the bottom of the outer support 2. A wear-resistant strip 14 is installed at the bottom of the isolation ring 13. The wear-resistant strip 14 is made of rubber material. The isolation ring 13 at the bottom of the outer support 2 and the wear-resistant strip 14 at the bottom of the isolation ring 13 are made of rubber material, which can further enhance the wear resistance of the bottom and reduce the friction loss between the bottom and the placement surface. At the same time, the isolation ring 13 also helps to reinforce the stability of the bottom of the container bag.

[0027] like Figure 1 and 2 As shown, a baffle ring 10 is installed on the top of the bag mouth reinforcement seat 5, and multiple overflow ports 11 are opened at the bottom of the baffle ring 10 for material overflow. When filling goods into the container bag, the baffle ring 10 can prevent excessive material overflow and play a certain blocking role, while the overflow ports 11 allow an appropriate amount of material to overflow during the filling process, so as to ensure the uniformity and rationality of the filling of materials in the container bag and avoid local overfilling and excessive pressure on the bag body.

[0028] The working principle is as follows: In practical use, the FIBC (Flexible Intermediate Bulk Container) of this invention demonstrates excellent durability and tear resistance, primarily based on the following principles:

[0029] Bottom reinforcement and load-bearing principle: The bottom of the container bag is reinforced by an inner lining ring 1 and an outer support 2. The inner lining ring 1 is fixedly connected to the lower edge of the inner wall of the bag body 3, and the outer support 2 is fixedly connected to the bottom of the bag body 3. This structural design increases the strength and stability of the bottom, enabling it to better bear the weight of the goods. During placement and transportation, when the goods exert pressure on the bottom of the bag, the outer support 2 and the inner lining ring 1 work together to evenly distribute the pressure, preventing the bottom of the bag from breaking due to excessive local stress.

[0030] The bag body has a multi-layer protection principle: From the outside to the inside, the bag body 3 is provided with a wear-resistant layer 32, a reinforcing layer 31, and a protective layer 33. The wear-resistant layer 32 is made of polyester film material, which can provide wear-resistant and scratch-resistant protection. During transportation and loading and unloading, when the bag body comes into contact with other objects or is rubbed, the wear-resistant layer 32 first bears the external force, preventing the bag surface from being scratched or worn. The reinforcing layer 31 is made of polypropylene material. It is located in the middle of the bag body and mainly bears the weight of the goods and impact forces. When the bag body is subjected to external forces, the reinforcing layer 31 can effectively disperse and bear the tensile force to prevent the bag body from tearing. For example, during the hoisting process, the tensile force transmitted by the sling 7 is transmitted to the bag body through the bag mouth reinforcement seat 5. The reinforcing layer 31 can bear and disperse these tensile forces. The protective layer 33 is made of polyethylene film material. It is located inside the bag body. Its main function is to prevent the goods from reacting chemically with the bag body material. It can also play a certain role in moisture protection and protect the quality of the goods.

[0031] The connection and force transmission principle between the sling 7 and the bag body: The sling 7 is made of high-strength polyester fiber material. Both slings 7 are fixedly connected to the bag mouth reinforcement seat 5. The bag mouth reinforcement seat 5 has a buffer pad 6 fixedly connected inside. One side of the buffer pad 6 is fixedly connected to the bag body 3. The bottom of the sling 7 is stitched with the bag body 3 and the bag mouth reinforcement seat 5 through multiple stitches with high-strength thread. During the hoisting process, the sling 7 bears the tension. The tension is first applied to the bag mouth reinforcement seat 5. Due to the presence of the buffer pad 6, it can play a buffering role, reducing the impact of the tension on the connection between the bag mouth reinforcement seat 5 and the bag body 3. Then, the tension is evenly transmitted to the bag body 3 through the bag mouth reinforcement seat 5. The reinforcement layer 31 of the bag body 3 can effectively disperse and bear the tension, preventing the bag body from tearing.

[0032] Overall structural reinforcement and stress distribution principle: Multiple reinforcing bands 4 are fixedly connected to the outer side of the bag mouth reinforcement seat 5 and the outer support seat 2. Reinforcing bands 8 are fixedly connected to adjacent groups of reinforcing bands 4. The setting of these reinforcing bands 4 and reinforcing bands 8 further improves the overall load-bearing capacity and stress distribution capacity of the container bag. When the container bag is subjected to external force, whether it is the tension from the top, such as during hoisting, or the pressure from the side, such as during stacking or transportation, the reinforcing bands 4 and reinforcing bands 8 can evenly distribute the external force to the entire container bag structure, avoiding excessive local stress that could lead to damage. At the same time, multiple grooves 9 are opened on the outer side of the reinforcing bands 8. These grooves 9 may help to increase the flexibility and deformation capacity of the reinforcing bands 8 to a certain extent, so that it can better adapt to the deformation requirements under the action of external force. Through reasonable structural design and material selection, this container bag with anti-damage structure effectively improves the damage resistance of the container bag and extends its service life.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
