DETAILED DESCRIPTION

[0024] The packaging bag contains a high-temperature liquid, but during transportation, the packaging bag may be subjected to various impacts and vibrations. When the packaging bag is impacted, it may deform or break, which may lead to leakage of the high-temperature liquid, reduce the safety of the packaging bag, and damage the liquid inside the packaging bag.

[0025] Based on this, the problem of liquid inside the packaging bag deforming or breaking during transportation can be improved in related technologies.

[0026] Please see Figures 1 to 6 A heat-resistant packaging bag includes a packaging bag body 1, a reinforcing component 2, a shock-absorbing component 3, and a sealing component 5. The reinforcing component 2 is disposed on the side of the packaging bag body 1, the shock-absorbing component 3 is disposed on the bottom of the packaging bag body 1, and the sealing component 5 is disposed on the packaging bag body 1. The reinforcing component 2 is used to increase the strength of the packaging bag body 1, the shock-absorbing component 3 is used to absorb shock from the packaging bag, and the sealing component 5 is used to seal the opening of the packaging bag.

[0027] Please see Figure 1 and Figure 2 The sealing component 5 includes a first opening 51, an external thread 52, and a sealing cap 53. The packaging bag body 1 has the first opening 51, and the packaging bag body 1 has the external thread 52 at one end of the first opening 51. The sealing cap 53 is threadedly connected to the packaging bag body 1 through the external thread 52. The reinforcing component 2 includes a first fixing plate 21, a first connecting plate 22, and a second connecting plate 23. The first fixing plate 21 is disposed on the packaging bag body 1, and multiple sets of the first fixing plate 21 are disposed. The first connecting plate 22 is disposed on the packaging bag body 1, and both ends of the first connecting plate 22 are fixedly connected to the first fixing plate 21, respectively. The second connecting plate 23 is disposed on the packaging bag body 1, and both ends of the second connecting plate 23 are fixedly connected to the first fixing plate 21, respectively. Multiple sets of the reinforcing component 2 are disposed.

[0028] With such an arrangement, when the user uses the heat-resistant packaging bag, the user needs to fill the packaging bag with high-temperature liquid. The user pours the high-temperature liquid into the packaging bag body 1 through the first opening 51, and then the user threadedly connects the sealing cover 53 to the packaging bag body 1 through the external thread 52 to block the first opening 51 and seal the packaging bag body 1, preventing the high-temperature liquid in the packaging bag body 1 from flowing out during transportation, preventing accidental contact of the high-temperature liquid with the human body or other objects, reducing the risk of burns and other safety accidents, and improving the safety of transportation. The first fixed plate 21 is provided with four first fixed plates 21 fixedly connected to the four side corners of the packaging bag body 1, and the two ends of the first connecting plate 22 are fixedly connected to the two first fixed plates 21 to strengthen the strength of the packaging bag body 1. The two ends of the second connecting plate 23 are also fixedly connected to the two first fixed plates 21 to strengthen the structure of the packaging bag body 1. High-temperature liquid can exert pressure on the packaging bag, especially during transportation or storage. The reinforcing assembly 2 can improve the durability of the packaging bag and reduce the risk of damage. In addition, in a high-temperature environment, the material may expand or shrink. The reinforcing assembly 2 can provide additional support to prevent the packaging bag from breaking due to thermal expansion and contraction. The reinforcing assembly 2 can significantly improve the pressure-bearing capacity of the packaging bag, ensuring that even when filled with high-temperature liquid, the packaging bag can withstand internal pressure without deformation, enhancing the structural strength of the packaging bag and prolonging its service life.

[0029] Please refer to Figures 3 to 5 The damping assembly 3 includes an elastic bottom plate 31, a fixed plate 32, a first spring 33, a connecting column 34, a sliding column 35, and a fixed disc 36. The elastic bottom plate 31 is fixedly connected to the bottom end of the packaging bag body 1. The fixed plate 32 is fixedly connected to the bottom end of the packaging bag body 1. The connecting column 34 is fixedly connected to the fixed plate 32. A first sliding groove 4 is formed in the connecting column 34. The fixed disc 36 is fixedly connected to the elastic bottom plate 31. The sliding column 35 is fixedly connected to the fixed disc 36, and the sliding column 35 is slidingly connected to the first sliding groove 4. One end of the first spring 33 abuts against the fixed plate 32, and the other end of the first spring 33 abuts against the fixed disc 36.

[0030] In this way, after the user pours the high-temperature liquid into the packaging bag body 1, the high-temperature liquid in the packaging bag body 1 extrudes the bottom end of the packaging bag body 1, driving the fixed plate 32 to move downward, and at the same time, the fixed plate 32 compresses the first spring 33, so that the sliding column 35 slides on the first sliding groove 4, and the first spring 33 rebounds to give the fixed plate 32 an upward force. During transportation, the packaging bag may be subjected to various impacts and vibrations, and the first spring 33 can absorb these impacts and reduce the direct impact on the internal high-temperature liquid, preventing the packaging bag from deforming or rupturing when subjected to impact, thereby avoiding leakage of the high-temperature liquid and ensuring the safety of transportation and storage. The high-temperature liquid may be shaken violently when subjected to a severe impact, and the damping assembly 3 can reduce such shaking to protect the liquid from damage and avoid changes in the internal pressure of the container caused by shaking, thereby prolonging the service life.

[0031] Please refer to Figure 6 The packaging bag body 1 is also provided with a handle 6, and the packaging bag body 1 further comprises an outer layer 7, a heat-sealing layer 8, a functional layer 9, a heat-resistant layer 10, and an inner layer 11. The heat-sealing layer 8 is fixedly connected to the outer layer 7, the functional layer 9 is fixedly connected to the side of the heat-sealing layer 8 away from the outer layer 7, the heat-resistant layer 10 is fixedly connected to the side of the functional layer 9 away from the heat-sealing layer 8, and the inner layer 11 is fixedly connected to the side of the heat-resistant layer 10 away from the functional layer 9.

[0032] In this way, when the user uses the high-temperature resistant packaging bag, the outer layer of the packaging bag body 1 is made of polypropylene PP material, which has good heat resistance and mechanical strength. The heat-sealing layer 8 is bonded to the outer layer 7, and the heat-sealing layer 8 is made of aluminum foil material, which provides excellent barrier properties to prevent heat transfer and gas permeation, preventing the liquid in the packaging bag body 1 from coming into contact with air. The functional layer 9 is made of polyimide material, which can remain stable at very high temperatures, typically in the temperature range of -269℃ to 350℃. The heat-resistant layer 10 is made of polyamide PA material, which can prevent deformation or melting of ordinary packaging materials at high temperatures. The inner layer 11 is made of polyethylene PE material, which has good sealing and softness and is suitable for contacting the contents.

[0033] Working principle: when using the heat-resistant packaging bag, the user needs to put high-temperature liquid into the packaging bag, the user pours the high-temperature liquid into the packaging bag body 1 through the first opening 51, and then the user screws the sealing cover 53 on the packaging bag body 1 through the outer thread 52, seals the first opening 51, the two ends of the first connecting plate 22 are fixedly connected with the two first fixed plates 21 respectively, the strength of the packaging bag body 1 is strengthened, the two ends of the second connecting plate 23 are also fixedly connected with the two first fixed plates 21, after the user pours the high-temperature liquid into the packaging bag body 1, the high-temperature liquid in the packaging bag body 1 extrudes the bottom end of the packaging bag body 1, drives the fixed plate 32 to move downward, and at the same time, the fixed plate 32 compresses the first spring 33, so that the sliding column 35 slides on the first sliding groove 4, and the first spring 33 rebounds to give the fixed plate 32 an upward force.

[0034] The above is only the preferred specific implementation of the present application; however, the protection scope of the present application is not limited to this.
