Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a moisture-proof ton bag. Background Art

[0002] Ton bags are a kind of flexible transport packaging container, which can be used to transport powdery materials and granular materials, and have the advantages of large capacity and light weight. Ton bags can be used with cranes or forklifts to realize unitized transportation, which is very convenient for loading, unloading and handling. Therefore, they are widely used in the transportation of powdery materials, granular materials and block materials.

[0003] Traditional ton bags are often made of polypropylene materials only, and their moisture-proof performance is extremely poor. Even if some ton bags have a layer of PE inner film inside, they are only sealed by a single tie rope at the feed inlet, which is difficult to prevent moisture in the air from entering the materials in the ton bag, and the moisture-proof performance is still poor. They are not suitable for materials with high moisture-proof requirements, especially for deliquescent materials that are transported over long distances by sea, and often cannot meet the transportation requirements.

[0004] Therefore, providing a ton bag with excellent moisture-proof performance has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] The utility model discloses a moisture-proof ton bag, which solves the technical problem that the ton bag in the related technology has poor moisture-proof performance.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions:

[0007] The utility model discloses a moisture-proof ton bag, comprising a bag body, on which a feed port is formed, wherein the bag body has a storage space, and the bag body comprises at least an outer layer, a first inner layer and a second inner layer, wherein the first inner layer and the second inner layer are arranged in the outer layer, and an inner film tie rope and an inner film closing rope are arranged on the first inner layer at the feed port, and a portion of the second inner layer between the inner film tie rope and the inner film closing rope forms an accommodating space, wherein the accommodating space is used for placing moisture-proof parts, and an outer bag tie rope is arranged on the outer layer at the feed port, and the outer bag tie rope is used for controlling the opening size of the feed port.

[0010] According to an optional embodiment, the moisture-proof bulk bag further comprises lifting ears, wherein the lifting ears are arranged at the four corners of the bag body, and the lifting ears have reinforcing ribs, and the reinforcing ribs are used to keep the lifting ears upright in a natural state.

[0011] According to an optional embodiment, the moisture-proof big bag further comprises a connecting cable, and the connecting cable is used to connect two adjacent lifting ears.

[0012] According to an optional embodiment, a first reinforcement belt is provided on the bag body, and the first reinforcement belt is arranged along the circumferential direction of the bag body.

[0013] According to an optional embodiment, the height of the first reinforcement belt from the top of the bag body satisfies: h=H / 4, wherein h is the height of the first reinforcement belt from the top of the bag body, and H is the height of the bag body.

[0017] The technical solution adopted by the utility model can achieve the following beneficial effects:

[0018] On the one hand, the moisture-proof ton bag of the utility model forms a storage space at the feed inlet with the second inner layer between the inner membrane tie rope and the inner membrane closing rope.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0031] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] Traditional ton bags only have one layer of PE inner film, which makes the ton bag body have poor moisture resistance. On the other hand, it is difficult to completely seal the feed inlet through the tying rope, and air will inevitably enter the storage space from the feed inlet, causing the transported materials to be damp. Therefore, it is not suitable for materials with high moisture resistance requirements, especially for deliquescent materials that are transported over long distances. For example, magnesium-based materials that are easy to absorb moisture.

[0033] The present application adopts a double-layer inner film to improve the moisture-proof performance of the bag body; on the other hand, by forming a accommodating space at the feed port, the moisture-proof parts in the accommodating space can adsorb and dry the humid air entering the bag body through the feed port, thereby improving the moisture-proof effect at the bag mouth of the ton bag and greatly reducing the risk of moisture in the transported materials.

[0034] The following is combined with Figures 1 to 6 , the moisture-proof bulk bag provided by the present application is described in detail through specific embodiments and application scenarios.

[0035] The moisture-proof bulk bag of this embodiment includes a bag body 100. Figure 1 The bag body 100 is the main body of the moisture-proof bulk bag, and the bag body 100 has a storage space 100a, which is used to fill the materials to be transported. Figure 1 As shown. Exemplarily, the storage space 100a is used to load deliquescent substances, such as a highly active magnesium-based cobalt precipitation agent.

[0036] In some embodiments, a feed port 200 is formed on the bag body 100, and the feed port 200 is used to allow the material to be transported to enter the storage space 100a. Figure 1 As shown. Exemplarily, the feed opening 200 is located in the middle of the upper part of the bag body 100, and the feed opening 200 at least partially protrudes from the bag body 100, as shown in FIG. Figure 1 The opening size of the feed inlet 200 is smaller than the size of the upper surface of the bag body 100. The feed inlet 200 and the bag body 100 are an integrated structure.

[0037] In some embodiments, the bag body 100 includes at least an outer layer 110, a first inner layer 120 and a second inner layer 130. Figure 2 The first inner layer 120 and the second inner layer 130 are arranged inside the outer layer 110, as shown in FIG. Figure 2 As shown. Exemplarily, the first inner layer 120 and the second inner layer 130 are PE inner film molded lacing bags. PE inner film molded lacing bags have the advantages of strong tensile strength, good chemical corrosion resistance, flexibility and waterproofness. PE inner film molded lacing bags are products in the prior art and are not described here. The moisture-proof ton bag of this embodiment is provided with a first inner layer 120 and a second inner layer 130 in the outer layer 110. The double inner layers can play a double-effect moisture-proof role, which can improve its moisture-proof performance compared to the ton bag with only a single inner layer in the prior art.

[0038] In some embodiments, the outer layer 110 is made of polypropylene material with UV resistance. Polypropylene material with UV resistance is a product in the prior art and will not be described in detail here. In the moisture-proof ton bag of this embodiment, the outer layer 110 is made of polypropylene material with UV resistance, so that the outer layer 110 not only has high strength, but also has UV resistance, which can improve the quality of the bag body 100 and reduce the impact of ultraviolet rays on the transported materials, so that the ton bag of this embodiment can also be used in high altitude and strong ultraviolet environments.

[0039] In some embodiments, the outer layer 110 is made of ordinary polypropylene material.

[0040] In some embodiments, the first inner layer 120 at the feed port 200 is provided with an inner film tie rope 210 and an inner film closing rope 220, such as Figure 4 As shown. Exemplarily, the inner film tie rope 210 is used to tie and seal the end of the first inner layer 120 and the second inner layer 130 at the feed inlet 200 close to the bag body 100, and the inner film closing rope 220 is used to tie and seal the end of the first inner layer 120 and the second inner layer 130 at the feed inlet 200 away from the bag body 100 (when the feed inlet 200 is in an upright state), so that the part of the second inner layer 130 between the inner film tie rope 210 and the inner film closing rope 220 can be formed into an accommodating space, and the accommodating space can be used to place the moisture-proof member 230, such as Figure 4 and Figure 5 As shown. Exemplarily, the moisture-proof member 230 may be a desiccant in the prior art.

[0041] Exemplarily, the inner film tie rope 210 and the inner film closing rope 220 may be two independent tie ropes integrated on the bag body 100; or may be one tie rope integrated on the bag body 100, a part of which is formed as the inner film tie rope 210, and another part is formed as the inner film closing rope 220. The lengths of the inner film tie rope 210 and the inner film closing rope 220 are not limited.

[0042] In some embodiments, an outer bag tie rope 240 is provided on the outer layer 110 at the feed inlet 200, and the outer bag tie rope 240 is used to control the opening size of the feed inlet 200, such as Figure 4 and Figure 5 As shown. Exemplarily, the outer bag tie rope 240 is integrated on the bag body 100, and by pulling the outer bag tie rope 240, the opening of the outer layer 110 at the feed port 200 can be enlarged or reduced.

[0043] Exemplary, combined Figure 4 and Figure 5After the material to be transported is loaded, the inner film tie rope 210 is used to tie and seal the first inner layer 120 and the second inner layer 130 at the feed port 200 close to the bag body 100; then the moisture-proof component 230 is placed in the second inner layer 130 above the inner film tie rope 210; the first inner layer 120 and the second inner layer 130 at the feed port 200 are bent and their openings are facing the bag body 100; the inner film closing rope 220 is used to tie and seal the first inner layer 120 and the second inner layer 130 at the feed port 200 away from the bag body 100 (or the opening of the feed port 200); finally, the outer layer 110 is tightened using the outer bag tie rope 240 to achieve the sealing of the feed port 200.

[0044] In the moisture-proof ton bag of this embodiment, at the feed inlet 200, the portion of the second inner layer 130 between the inner film tie rope 210 and the inner film closing rope 220 forms a storage space, and a moisture-proof part 230 is placed in the storage space. The moisture-proof part 230 can be used to adsorb and dry the humid air entering the bag body 100 through the feed inlet 200, thereby improving the moisture-proof effect at the mouth of the ton bag and greatly reducing the risk of moisture in the transported materials. On the other hand, the moisture-proof ton bag of this embodiment forms a storage space for filling the moisture-proof part 230 at the feed inlet 200, and only a small number of moisture-proof parts 230 are needed to achieve a moisture-proof effect. Moreover, the moisture-proof part 230 can be filled after the transported materials are loaded, which has the advantages of convenient filling of the moisture-proof part 230 and will not affect the loading of the transported materials.

[0045] The moisture-proof ton bag of this embodiment can effectively prevent the materials from getting damp during long-distance transportation of deliquescent materials, and also has a significant effect in preventing the materials from being denatured by ultraviolet rays in areas with high altitudes and strong ultraviolet rays. The moisture-proof ton bag of this embodiment is of great significance and value, especially in the long-distance export of highly active magnesium-based cobalt precipitation agents by sea transportation.

[0046] In some embodiments, a waterproof coating layer is provided on the outer layer 110. Exemplarily, the waterproof coating layer may be located on the inner side and / or outer side of the outer layer 110. Exemplarily, the waterproof coating layer is a polyurethane coating layer, a polyacrylate coating layer, an epoxy resin coating layer, etc., which is formed by spraying on the inner side and / or outer side of the outer layer 110. The moisture-proof ton bag of this embodiment, by providing a waterproof coating layer on the inner side and / or outer side of the outer layer 110, can form a waterproof film on the inner side and / or outer side of the outer layer 110, which can further improve the moisture-proof performance of the bag body 100.

[0047] In some embodiments, the first inner layer 120 and the second inner layer 130 are connected to each other, and a first exhaust hole 141 is provided at the connection between the first inner layer 120 and the second inner layer 130. The first exhaust hole 141 is used to exhaust the gas between the first inner layer 120 and the second inner layer 130. Figure 2As shown. Exemplarily, the first exhaust holes 141 are located on the upper surfaces of the first inner layer 120 and the second inner layer 130 , and the number of the first exhaust holes 141 is 2 to 20, and the first exhaust holes 141 are evenly distributed along the circumferential direction of the upper surface of the bag body 100 .

[0048] Exemplarily, the four sides of the lower surface of the first inner layer 120 and the second inner layer 130 are welded and fixed, and after the aluminum foil is fixed at the position reserved for the first exhaust hole 141 in the first inner layer 120 and the second inner layer 130, the four sides of the upper surface of the first inner layer 120 and the second inner layer 130 are welded and fixed, and then the aluminum foil is removed, so that the first exhaust hole 141 can be formed at the welding point on the upper surface of the first inner layer 120 and the second inner layer 130.

[0049] The inventor found in the study that the bag body 100 has a first inner layer 120 and a second inner layer 130, and the first inner layer 120 and the second inner layer 130 are usually welded together to prevent the material from entering between the first inner layer 120 and the second inner layer 130 during feeding. With this structure, when feeding into the storage space 100a, air bubbles are easily generated between the first inner layer 120 and the second inner layer 130, which leads to a reduction in the load of the first inner layer 120 and the second inner layer 130 and rupture. In the scheme of this embodiment, a first exhaust hole 141 is provided at the connection between the first inner layer 120 and the second inner layer 130, so that the gas between the first inner layer 120 and the second inner layer 130 can be discharged from the first exhaust hole 141 during the feeding process, reducing the hidden danger of air bubbles formed between the first inner layer 120 and the second inner layer 130, thereby reducing the risk of rupture of the first inner layer 120 and the second inner layer 130.

[0050] In some embodiments, the outer layer 110 is connected to the first inner layer 120 and the second inner layer 130, and a second exhaust hole 142 is provided at the connection between the outer layer 110 and the first inner layer 120 and the second inner layer 130. The second exhaust hole 142 is used to exhaust the gas between the outer layer 110 and the first inner layer 120. Figure 2 As shown. Exemplarily, the second exhaust holes 142 are located on the upper surface of the outer layer 110 and the first inner layer 120 and the second inner layer 130, and the number of the second exhaust holes 142 is 2 to 20, and the second exhaust holes 142 are evenly distributed along the circumferential direction of the upper surface of the bag body 100.

[0051] Exemplarily, after the aluminum foil is fixed at the position reserved for the second exhaust hole 142 between the outer layer 110 and the first inner layer 120 and the second inner layer 130, the eight overlapping sides of the first inner layer 120 and the second inner layer 130 are welded and fixed to the outer layer 110, and then the aluminum foil is removed, so that the second exhaust hole 142 can be formed at the welding point between the outer layer 110 and the upper surface of the first inner layer 120 and the second inner layer 130.

[0052] As above, in order to prevent the material from entering between the outer layer 110 and the first inner layer 120 during feeding, the outer layer 110 and the first inner layer 120 are usually welded together. With this structure, when feeding into the storage space 100a, large air bubbles are generated between the outer layer 110 and the first inner layer 120, and the air bubbles will occupy the storage space 100a, resulting in a reduction in the storage capacity of the storage space 100a. In the scheme of this embodiment, during the feeding process, the air between the outer layer 110 and the first inner layer 120 can be discharged through the second exhaust hole 142 to avoid the formation of air bubbles, thereby ensuring the storage capacity of the storage space 100a; it is also beneficial to fill the material tightly to provide a certain support effect to the bag body 100, thereby improving the anti-destruction performance of the bag body 100.

[0053] In some embodiments, the first exhaust hole 141 and the second exhaust hole 142 are staggered. That is, the first exhaust hole 141 and the second exhaust hole 142 are not aligned in the circumferential direction of the bag body 100. The staggered first exhaust hole 141 and the second exhaust hole 142 can prevent the exhaust process between the first inner layer 120 and the second inner layer 130 from interfering with the exhaust process between the outer layer 110 and the first inner layer 120.

[0054] In some embodiments, the moisture-proof bulk bag further includes a lifting lug 300, which is disposed at the four corners of the bag body 100. Figure 1 Preferably, the lifting ear 300 has a reinforcing rib 310, and the reinforcing rib 310 is used to keep the lifting ear 300 upright in a natural state. Figure 6 As shown. Exemplarily, the reinforcing rib 310 is made of a hard material such as steel wire, so that the lifting lug 300 can be in an "n"-shaped upright shape in a natural state.

[0055] The handling process of ton bags often requires mechanical cooperation. The lifting lugs 300 of traditional ton bags are usually short and poorly upright, which is not convenient for mechanical lifting operations and affects the work efficiency. In the solution of this embodiment, the lifting lug 300 has a reinforcing rib 310, so that the lifting lug 300 can remain upright in a natural state, which is conducive to the machine passing through the lifting lug 300 for lifting operations, and can improve the work efficiency.

[0056] In some embodiments, the moisture-proof bulk bag further includes a connecting cable 400, such as Figure 1 As shown. The connecting cable 400 is used to connect two adjacent lifting ears 300. Exemplarily, there are four connecting cables 400, and each connecting cable 400 is provided between two adjacent lifting ears 300. Exemplarily, there are two connecting cables 400, which are respectively provided between the two lifting ears 300 on the left and between the two lifting ears 300 on the right. Exemplarily, the connecting cable 400 passes through the two lifting ears 300 and is fixedly connected to the lifting ears 300.

[0057] In the solution of this embodiment, a connecting cable 400 is used to connect two adjacent lifting ears 300. When a machine is used for lifting operations, the machine can also pass through the connecting cable 400 to perform lifting operations, thereby increasing the number of mechanical lifting methods. In addition, the space formed by the connecting cable 400 for the machine to pass through is significantly larger than the lifting ear 300, making it easy for the machine to pass through the connecting cable 400 to perform lifting operations.

[0058] In some embodiments, the bag body 100 is provided with a first reinforcement belt 150, and the first reinforcement belt 150 is arranged along the circumferential direction of the bag body 100, such as Figure 1 As shown. Exemplarily, the first reinforcement belt 150 is located around the bag body 100, that is, the first reinforcement belt 150 can also be called an annular reinforcement belt. Exemplarily, 2 to 4 annular reinforcement belts are provided at different heights of the bag body 100. Exemplarily, the first reinforcement belt 150 is sewn to the inner surface or the outer surface of the outer layer 110. In the scheme of this embodiment, the bag body 100 is provided with the first reinforcement belt 150, which can improve the tensile strength of the bag body 100 when loaded and reduce the risk of tearing and damage of the bag body 100 during lifting operations.

[0059] In some embodiments, the height of the first reinforcing tape 150 from the top of the bag body 100 satisfies: h=H / 4, where h is the height of the first reinforcing tape 150 from the top of the bag body 100, and H is the height of the bag body 100. Placing the first reinforcing tape 150 above the bag body 100 helps reduce the risk of tearing and damage of the bag body 100.

[0060] In some embodiments, the ear 300 is fixedly connected to the bag body 100 through a fixing belt 320, and the fixing belt 320 extends to the first reinforcement belt 150 and is fixedly connected to the first reinforcement belt 150, such as Figure 1 As shown. Exemplarily, the ear 300 is sewn to the bag body 100 through the fixing belt 320, and the fixing belt 320 is extended to the first reinforcement belt 150 and fixedly connected to the first reinforcement belt 150, so as to enhance the strength of each other. That is, the strength of the first reinforcement belt 150 can be enhanced by the fixing belt 320, and the strength of the fixing belt 320 can be enhanced by the first reinforcement belt 150.

[0061] In some embodiments, the bag body 100 is further provided with a second reinforcement strip 160, and the second reinforcement strip 160 is located on both sides of the longitudinal edge 100b of the bag body 100, such as Figure 1 The bag body 100 has four longitudinal edges 100b, and correspondingly, eight second reinforcement strips 160 are provided on the bag body 100. In the solution of this embodiment, the second reinforcement strips 160 can further improve the tensile strength of the bag body 100 when loaded, and reduce the risk of tearing and damage of the bag body 100 during lifting operations.

[0062] In some embodiments, the bag body 100 is further provided with a third reinforcement belt 170, the third reinforcement belt 170 is located at the bottom of the bag body 100, and the third reinforcement belt 170 is arranged in a cross pattern, such as Figure 1 and Figure 3 As shown. Exemplarily, the third reinforcement belts 170 are arranged in a "cross" shape. In the solution of this embodiment, the third reinforcement belts 170 can further improve the tensile strength of the bag body 100 when loaded, and reduce the risk of tearing and damage of the bag body 100 during lifting operations.

[0063] That is, the solution of this embodiment can improve the tensile strength of the side and bottom of the bag body 100 through the first reinforcement belt 150, the second reinforcement belt 160 and the third reinforcement belt 170 respectively, and reduce the risk of tearing and damage of the bag body 100 during lifting operations.

[0064] In some embodiments, the bag body 100 is further provided with a storage bag 180, which is located on the side of the bag body 100. Figure 1 As shown. Exemplarily, the storage pockets 180 may be provided on all four sides of the bag body 100, or may be provided on only one or two sides of the bag body 100. Exemplarily, the storage pockets 180 are connected to the bag body 100 by sewing. Documents related to the transported materials may be placed in the storage pockets 180.
