Description

Technical Field

[0001] This utility model relates to a container bag, specifically a container bag consisting of an aluminum foil inner bag and a PP outer bag. Background Technology

[0002] FIBCs, also known as flexible container bags, ton bags, or space bags, are a type of unitized container. When used with cranes or forklifts, they enable unitized transport. They are suitable for transporting large quantities of bulk, powdery, or granular materials. FIBCs are a type of flexible transport packaging container widely used for transporting powdery, granular, or lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals. Developed countries commonly use FIBCs as packaging products for transportation and warehousing.

[0003] In our daily work, we have found that the outer bag of the container is single-function. In addition, when food is placed in the inner bag, a large amount of air enters the container, causing the container to expand in volume. Furthermore, when multiple containers are placed in the truck bed for transportation, they may squeeze each other and burst open. Utility Model Content

[0004] Purpose of the invention: The purpose of this utility model is to overcome the shortcomings of the prior art and provide a container bag with a long service life of outer bag, timely air release of inner bag, and safe use of aluminum foil inner bag and PP outer bag combination.

[0005] Technical Solution: To solve the above-mentioned technical problems, the present invention provides a combined container bag of aluminum foil inner bag and PP outer bag, comprising an aluminum foil inner bag and a PP outer bag. The aluminum foil inner bag has a breathable structure. The PP outer bag includes a bag body with straps. The bag body includes a waterproof layer, an antistatic layer inside the waterproof layer, a PP base layer inside the antistatic layer, and a wear-resistant layer inside the PP base layer. The breathable structure includes an air-gathering port, and a support sleeve is fixedly connected to the surface of the air-gathering port away from the aluminum foil inner bag. The air collection port is connected to the support sleeve. An air outlet is fixedly connected to the surface of the support sleeve away from the inner aluminum foil bag. The air outlet is connected to the support sleeve. A first rubber ring is fixedly connected to the inner surface of the support sleeve. The first rubber ring is located above the air outlet. A second rubber ring is fixedly connected to the inner surface of the support sleeve. The second rubber ring is located below the air outlet. An adjusting rod is threadedly connected to the surface of the support sleeve. An adjusting block is fixedly connected to the end of the adjusting rod away from the air collection port. A sealing ring is fixedly connected to the end of the adjusting rod away from the adjusting block. The sealing ring is inserted into the surface of the support sleeve.

[0006] Furthermore, the PP base layer is woven from warp and weft threads, both of which are PP yarns.

[0007] Furthermore, the waterproof layer is a PE film.

[0008] Furthermore, the wear-resistant layer is a toughened aluminum oxide layer.

[0009] Beneficial effects: Compared with the prior art, the significant advantages of this utility model are:

[0010] (1) The outer bag body includes a waterproof layer, an antistatic layer, a PP base layer, and a wear-resistant layer. It has good waterproof performance, good antistatic performance, and good wear resistance, which effectively improves its service life.

[0011] (2) By setting a breathable structure, when the aluminum foil inner bag is in use, it is convenient for workers to expel the air inside the aluminum foil inner bag. Rotating the adjusting block causes the adjusting rod to rotate, which in turn causes the closing ring to slide outward. The closing ring disengages from the bottom of the support sleeve. When the bottom of the adjusting rod abuts against the first rubber ring, the worker squeezes the aluminum foil inner bag, and the air inside the aluminum foil inner bag enters the air-gathering port. Then, the air enters the support sleeve through the air-gathering port and is discharged from the aluminum foil inner bag through the air outlet. Adjusting the adjusting rod causes the closing ring to insert into the bottom of the rotating sleeve, thus completing the air guiding. By setting a breathable structure, it is convenient for workers to expel the air inside the aluminum foil inner bag, avoiding the situation where the aluminum foil inner bag is squeezed and bursts during transportation due to air. This improves the practicality of the container bag and reduces the damage rate of the container bag. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3As shown, the combined aluminum foil inner bag and PP outer bag of this utility model comprises an aluminum foil inner bag 1 and a PP outer bag 2. A breathable structure 3 is provided on the aluminum foil inner bag 1. The PP outer bag 2 includes a bag body 2.1, on which a lifting strap 2.2 is provided. The bag body 2.1 includes a waterproof layer 4, an antistatic layer 5 is provided inside the waterproof layer 4, a PP base layer 6 is provided inside the antistatic layer 5, and a wear-resistant layer 7 is provided inside the PP base layer 6. The waterproof layer 4 is a PE film, and the PP base layer 6 is woven from warp and weft threads, both of which are PP yarns. The wear-resistant layer 7 is a toughened aluminum oxide layer. The breathable structure 3 includes an air-gathering port 38, and the surface of the air-gathering port 38 away from the aluminum foil inner bag 1 is fixedly connected to... A support sleeve 37 is attached, which communicates with the air collection port 38. An air outlet 32 ​​is fixedly connected to the surface of the support sleeve 37 away from the aluminum foil inner bag 1, and the air outlet 32 ​​communicates with the support sleeve 37. A first rubber ring 33 is fixedly connected to the inner surface of the support sleeve 37, and the first rubber ring 33 is located above the air outlet 32. A second rubber ring 35 is fixedly connected to the inner surface of the support sleeve 37, and the second rubber ring 35 is located below the air outlet 32. An adjusting rod 34 is threadedly connected to the surface of the support sleeve 37. An adjusting block 31 is fixedly connected to the end of the adjusting rod 34 away from the air collection port 38, and a sealing ring 36 is fixedly connected to the end of the adjusting rod 34 away from the adjusting block 31. The sealing ring 36 is inserted into the surface of the support sleeve 37.

[0017] This utility model's outer bag body includes a waterproof layer, an antistatic layer, a PP base layer, and a wear-resistant layer. It boasts excellent waterproof, antistatic, and wear-resistant properties, effectively extending its service life. By incorporating a breathable structure, it facilitates the expulsion of air from the inner aluminum foil bag during use. Rotating the adjusting block causes the adjusting rod to rotate, which in turn causes the sealing ring to slide outwards, disengaging from the bottom of the support sleeve. When the bottom of the adjusting rod abuts against the first rubber ring, the worker squeezes the inner aluminum foil bag, causing air to enter the air-gathering port. The air then enters the support sleeve through the air-gathering port and is expelled from the inner aluminum foil bag through the air outlet. Adjusting the adjusting rod inserts the sealing ring into the bottom of the rotating sleeve, completing the air ducting process. This breathable structure effectively facilitates the expulsion of air from the inner aluminum foil bag, preventing it from bursting due to air compression during transportation. This improves the practicality of the container bag and reduces its damage rate.

The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model. These improvements and modifications should also be considered as the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
