Technical Field
[0001] The utility model relates to the technical field of packaging bags, in particular to a self-shaping double-layer inflatable packaging bag. Background Art
[0002] In modern society, packaging bags have become the most common items for packaging various supplies. They can facilitate the transportation of goods during the production and circulation process and are easy to store. They are widely used in daily life and industrial production. Ordinary packaging bags can generally only package items. When the packaged items are fragile goods, during handling and jolting, the goods are likely to be damaged due to collisions with each other or with the means of transportation. Therefore, additional protective measures need to be taken for such goods.
[0003] To better solve the above problems, the existing technical solution is to design a double-layer inflatable packaging bag on the basis of the packaging bag, that is, the packaging bag is inflated and then sealed and wrapped outside the goods to be transported. In this way, when encountering bumps and other situations during transportation, the inflated packaging bag will produce buffering to protect the wrapped goods from being damaged. However, for the packaging of some handicrafts, especially those with relatively strange shapes and structures, the existing inflatable packaging bags cannot fully fit all angles of the packaging objects. This easily leads to the problem that the packaging objects slide inside the inflatable packaging bag after packaging is completed, and are damaged during long-term transportation. Moreover, generally ordinary inflatable packaging bags are removed by cutting, which makes it very inconvenient to check the packaging objects in the middle of the journey. The removed packaging bags need to be discarded, and new ones need to be taken for packaging, which cannot be reused and is relatively wasteful. Summary of the Utility Model
[0004] In view of the prior art, the purpose of the present utility model is to provide a self-shaping double-layer inflatable packaging bag for the above problems. It can adaptively shape and fit the packaging object during inflatable packaging according to the shape of the packaging object, and can be deflated, opened, and then inflated again for reuse.
[0005] To achieve the above purpose, the technical solution adopted by the present utility model is: a self-shaping double-layer inflatable packaging bag, including a bag body and a cavity. The bag body includes a pocket part with an airbag structure and a bag-sealing part. The pocket part is in the shape of a bag mouth, and a double-layer air ring is arranged at the opening thereof. The bag-sealing part is matched with the double-layer air ring to close the bag mouth to form a cavity. The pocket part and the bag-sealing part are respectively provided with air ports for inflating and deflating the pocket part and the bag-sealing part. A plurality of air columns are arranged on the pocket part, a connecting film is arranged between the air columns, and a communication air channel is also arranged between the air columns for ventilation.
[0006] As a further setting of the above solution, the air column is composed of several small square inflatable packages with connected air channels, and a spacer film is arranged between two adjacent inflatable packages. One side of the pocket part is arranged in a plane, and the inflatable package is set to be a structure that is fixedly inflated and bulged toward one side.
[0007] As a further setting of the above solution, the bag-sealing part has a flat structure with air hems at the edges. The interval between the double-layer air rings matches the thickness of the bag-sealing part, and a hemmed inflatable ring is arranged on one side of the double-layer air rings opposite to each other.
[0008] As a further setting of the above solution, the air port extends in a tubular shape and is arranged at the connection between the pocket part and the bag-sealing part. An air-port wrapping bag is also arranged at a position close to the air port on the outer side of the pocket part.
[0009] As a further setting of the above solution, two groups of the double-layer air rings are arranged on the bag body, and the openings of the two groups of double-layer air rings are arranged in opposite directions. The bag body is made of polytetrafluoroethylene material.
[0010] Beneficial effects: For the self-shaping double-layer inflatable packaging bag of the present utility model, by arranging a plurality of inflatable packages with single-sided inflation, the packaging can be carried out in multiple angles for the packaged object during use, improving the protection ability. And the design of single-way inflation enables the packaging bag of this embodiment to adapt to more packaged objects by turning inside out. The setting of the air port enables the packaging bag of this embodiment to be inflated and deflated repeatedly without damaging the seal of the inflatable package, facilitating the use of the user and the reuse of the packaging bag.

[0021] As a further setting of the above solution, two groups of the double-layer air rings 13 are arranged on the bag body 1, and the openings of the two groups of double-layer air rings 13 are arranged in opposite directions. The bag body 1 is made of polytetrafluoroethylene material.
[0022] Embodiment: A self-shaping double-layer inflatable packaging bag. The main material of the packaging bag in this embodiment is made of polytetrafluoroethylene material. The overall structure of the packaging bag includes the bag body 1 that constitutes the packaging bag and the cavity 2 inside the bag body 1 for placing objects. The bag body 1 includes a pocket part 11 with an airbag structure and a bag-sealing part 12. The pocket part 11 is in the shape of a bag opening, and a double-layer air ring 13 is arranged at its opening. The bag-sealing part 12 is matched with the double-layer air ring 13 to close the bag opening to form the cavity 2, as shown in Figure 3As shown, the double-layer air ring 13 includes two layers of inflatable layers, and a folded-edge inflatable ring 131 is provided on one side of the double-layer air ring 13. For example, Figure 3 During use, the bag-sealing part 12 is of a gas-folded edge 121 structure with a flat edge. When both are in an inflated state, they will form a limit fit, so that the double-layer air ring 13 stably clamps the bag-sealing part 12 in the shape of a lid, forming a simple closure of the opening of the bag body 1. According to actual needs and packaging requirements, tape can also be pasted on the outer layer to enhance the packaging strength.
[0023] In this embodiment, air ports 14 for inflating and deflating the pocket part 11 and the bag-sealing part 12 are respectively provided on the pocket part 11 and the bag-sealing part 12. A number of air columns 15 are provided on the pocket part 11, a connecting film 16 is provided between the air columns 15, and a communication air channel 17 is provided between the air columns 15. During use, by inflating through the air port 14 into the pocket part 11, the air can be compressed into the expansion bags 18 of each air column 15 through the communication air channel 17, so that they expand to clamp the packaged object.
[0024] As a further setting of the above solution, the air column 15 is composed of a number of small square expansion bags 18 with a communication air channel 17, and a spacer film 19 is provided between two adjacent expansion bags 18. One side of the pocket part 11 is arranged in a plane, and the expansion bag 18 is set to be a structure that is fixedly inflated and bulges to one side. The purpose of this setting is as Figure 2 、 Figure 4 As shown, the advantage of unilateral expansion is that it can form changes inwards or outwards, so as to adjust the size of the cavity 2. And when expanding inwards to squeeze the packaged object, the expansion size of unilateral expansion is larger, and there will be no outward deformation and expansion, and the clamping force is also stronger.
[0025] As a further setting of the above solution, the air port 14 extends in a tubular shape and is provided at the connection between the pocket part 11 and the bag-sealing part 12. An air-port bag 10 is also provided on the outside of the pocket part 11 near the air port 14. It should be noted that the air port 14 of this embodiment extends from the bag body 1. The purpose and advantage are that after inflation is completed, the tubular air port 14 can be directly knotted or heat-sealed. When deflating, only need to untie or make a hole in the heat-sealed part.
[0026] As a further setting of the above solution, two groups of the double-layer air rings 13 are provided on the bag body 1, and the openings of the two groups of double-layer air rings 13 are arranged in opposite directions. As Figure 3 shown, this setting enables the packaging bag of the present utility model, during use, to be like Figure 2 shown with the expansion bags 18 facing inwards or Figure 4 shown facing outwards. Among them, Figure 2As shown, facing inward, it can well solve the packaging problem of the packaging with a special-shaped structure in the prior art. After the packaging is placed in the cavity 2, it is inflated through the air port 14, and the expansion bag 18 is inflated to expand towards the packaging, so as to fill and expand the gaps at various angles between the packaging and the bag body 1, thus achieving better clamping protection for the packaging. And Figure 4 It is prepared for larger-volume packages.
[0027] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
