[0024] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0025] like Figure 1-5 As shown, the utility model is a heat preservation bag with a built-in invisible zipper, comprising a bag body 1, the bag body 1 comprising an inner lining layer 101, an insulation layer 102 is arranged on the outer side of the inner lining layer 101, a surface layer 103 is arranged on the side of the insulation layer 102 away from the inner lining layer 101, and a waterproof layer 104 is arranged on the side of the surface layer 103 away from the insulation layer 102. The arrangement of the insulation layer 102 enables the bag body 1 to have good heat preservation performance, and the arrangement of the waterproof layer 104 effectively increases the overall waterproof performance of the bag body 1, a first zipper 2 is arranged at the upper end opening of the bag body 1, and the first zipper 2 is located inside the bag body 1. When the bag body 1 is sealed, the first zipper 2 closes the upper end of the bag body 1, which is relatively close to the zipper installed at the end. The chain makes the insulation bag have better insulation performance. A connecting belt 3 is provided on the upper end of one side of the bag body 1, and the upper part of the connecting belt 3 is fixedly connected to the first connecting piece 4. A second connecting piece 5 is provided on the upper end of the bag body 1 away from the connecting belt 3, and the first connecting piece 4 can be fixedly connected to the second connecting piece 5. After the first zipper 2 seals the bag body 1, the upper end of the bag body 1 is rolled up. After the rolling is completed, the first connecting piece 4 is inserted into the second connecting piece 5, so that the connecting belt 3 can fix the rolled-up part of the upper end of the bag body 1. The bag body 1 is provided with a side pocket 6 below the second connecting piece 5, and the bag body 1 is provided with a second zipper 7 at the upper end of the side pocket 6, and the second zipper 7 can open and close the side pocket 6.
[0026] The first connecting member 4 includes a connecting ring 41 , which is fixedly connected to the connecting belt 3 . Both ends of the connecting ring 41 away from the connecting belt 3 are provided with connecting rods 42 . One end of the connecting rod 42 away from the connecting ring 41 is fixedly connected to a clamping block 43 .
[0027] The second connecting member 5 includes a connecting sleeve 51, which is fixedly connected to the package body 1. A slot 52 matching the block 43 is provided on the connecting sleeve 51. The connecting rod 42 and the block 43 can be inserted into the connecting sleeve 51. Through the mutual cooperation between the block 43 and the slot 52, the first connecting member 4 and the second connecting member 5 can be stably connected.
[0028] The insulation layer 102 is an insulation cotton layer, which is a new type of non-toxic, harmless and pollution-free insulation material made of high-purity clay clinker, alumina powder, silica powder, chrome sand and other raw materials. The setting of the insulation layer 102 effectively increases the overall insulation performance of the package 1.
[0029] The waterproof layer 104 is a PU coating, which is a polyurethane coating. After coating, the fabric feels plump and elastic, and the surface has a film feel. The PU coating has the characteristics of wear resistance and wind resistance.
[0030] Both sides of the lower end of the bag body 1 are provided with wear-resistant cloth 8 , and the provision of the wear-resistant cloth 8 effectively increases the overall wear resistance of the bag body 1 .
[0031] The bag body 1 is provided with a handle 9 below the connecting belt 3 .
[0032] The bag body 1 is provided with a shoulder strap 10 below the handle 9 . The arrangement of the handle 9 and the shoulder strap 10 effectively improves the wear resistance of the bag body 1 .
[0033] Specifically, in the present invention, the setting of the insulation layer 102 enables the bag body 1 to have good insulation performance, and the setting of the waterproof layer 104 effectively increases the overall waterproof performance of the bag body 1. When the bag body 1 is sealed, the first zipper 2 closes the upper end of the inside of the bag body 1, which makes the insulation bag have better insulation performance compared to the zipper installed at the end. After the first zipper 2 seals the bag body 1, the upper end of the bag body 1 is rolled up. After the rolling is completed, the first connecting member 4 is inserted into the second connecting member 5, so that the connecting belt 3 can fix the rolled-up part of the upper end of the bag body 1.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
