[0025] See Figures 1-4 As shown, a courier bag of the present invention includes a bag body 10, which includes an inflatable inner bag 2 and an outer bag 1 arranged outside the inner bag 2. The opening of the inner bag 2 is located outside the opening of the outer bag 1. The inner bag 2 is provided with a first bag cap 21. The first bag cap 21 and / or the bag body of the inner bag 2 are provided with a first adhesive strip 3 for closing the bag opening of the inner bag 2; the outer bag 1 is provided with a second bag cap 11. The second bag cap 11 and / or the bag body of the outer bag 1 are provided with a second adhesive strip 4 for closing the bag opening of the outer bag 1. Specifically, in this embodiment, the first adhesive strip 3 is provided on the outer surface of the bag body of the inner bag 2 near the bag opening and extends along the extension direction of the bag opening of the inner bag 2. The first adhesive strip 3 is used to bond with the first bag cap 21. The second adhesive strip 4 is provided at the end position of the inner surface of the second bag cap 11 of the outer bag 1 and extends along the extension direction of the bag opening of the outer bag 1. The second adhesive strip 4 is used to bond with the bag body of the outer bag 1. The second bag cap 11 is located on the same side as the first bag cap 21, and the second bag cap 11 protrudes from the first bag cap 21 in a direction perpendicular to the extension direction of the bag opening of the outer bag 1. The first and second adhesive strips 3 and 4 are respectively covered with release films (not shown in the figure). Figure 1 In the figure, the direction of the Y-axis is the extension direction of the bag opening of the inner bag 2 and the bag opening of the outer bag 1. The bag opening of the outer bag 1 and the bag opening of the inner bag 2 are the bag openings of the bag body 10. The direction of the X-axis indicates the bag depth direction of the bag body 10, that is, the depth direction of the bag body 10.

[0026] In this embodiment, the inner bag 2 is formed with an air storage chamber 22, which allows the inner bag 2 to swell after inflation, achieving a cushioning effect. The first bag cap 21 is provided with an air inlet structure, which communicates with the air storage chamber 22. The air inlet structure specifically includes an air inlet channel 24 extending along the direction of the inner bag 2's opening. A plurality of air storage chambers 22 are provided, distributed along the direction of the inner bag 2's opening. Adjacent air storage chambers 22 are spaced apart from each other, and each air storage chamber 22 is provided with a communication port 23 connecting it to the air inlet channel 24. In the figures, reference numerals 22, 23, and 24 are used to simply indicate the positions of the air storage chambers, communication ports, and air inlet channels, respectively. Opposing sides of each air storage chamber 22, along the direction of the inner bag 2's opening, are generally wavy and symmetrical. This results in the air storage chambers 22, when inflated, forming a roughly symmetrical structure consisting of a series of gourd balls connected in sequence. This structure is relatively stable, easily foldable, and offers excellent anti-slip properties and the ability to withstand high pressure. In other embodiments, the air storage chamber 22 is cylindrical after being inflated.

[0027] In this embodiment, the two opposing sides of the inner bag 2, along the direction of the inner bag's opening, are heat-sealed to the two opposing sides of the outer bag 1, along the direction of the outer bag's opening. This results in the inner bag 2 and the outer bag 1 each having two opposing sides. Each of the two sides of the inner bag 2 is provided with an air storage chamber 22, and the air storage chamber 22 on one side of the inner bag 2 is integrally connected to the air storage chamber 22 on the other side at the bottom of the inner bag 2. The first bag cap 21 of the inner bag 2 is provided on one side of the bag, and the first adhesive strip 3 is provided on the other side of the bag.

[0028] In this embodiment, the inner bag 2 is made of a double-layer film, and the air storage chamber 22 is formed between the double-layer film by heat sealing. The outer bag 2 is made of a colored film.

[0029] The above-mentioned bag bodies 10 are provided in a plurality, and the plurality of bag bodies 10 are integrally formed and arranged along the extension direction of the bag opening of the inner bag 2, and the bag openings of the plurality of bag bodies 10 face the same side, the first adhesive strips 3 on adjacent bag bodies 10 are integrally connected, and the second adhesive strips 4 on adjacent bag bodies 10 are also integrally connected. An easy-tear line 5 is provided between adjacent bag bodies 10, and the easy-tear line 5 extends along the depth direction of the bag. In this way, when tearing along the easy-tear line 5, a single bag body 10 can be separated. Figure 3 In the example, three bags 10 are used, but the present invention is not limited thereto. Under normal circumstances, the number of bags 10 is greater than or equal to ten, and the total length is several meters. The air inlet passages 24 of adjacent bags 10 are interconnected to form a main air inlet passage 101, and an air inlet port is provided at one end of the main air inlet passage 101.

[0030] The plurality of bag bodies 10 are rolled together along the arrangement direction of the plurality of bag bodies 10. When rolling, the second bag cap 11 is folded over the back of the outer bag 1 to expose the first bag cap 21, and the first adhesive strip 3 and the second adhesive strip 4 do not overlap. Figure 4 As shown. This allows the main air inlet channel 101 and air inlet openings of the multiple bag bodies 10 to be exposed to the outside, allowing users to use the automatic inflation and sealing equipment to continuously inflate and seal the communication openings 23 of each air storage chamber 22 when using the product, thereby improving packaging efficiency. Specifically, during inflation, the gas output by the automatic inflation and sealing equipment enters through the air inlet of the main air inlet channel 101 and then enters each air inlet channel 24 in sequence. The gas entering the air inlet channel 24 then enters each air storage chamber 22 through the communication openings 23 between each air storage chamber 22 and the air inlet channel 24. After inflation is completed, the automatic inflation and sealing equipment heat-seals the communication openings 23 between each air storage chamber 22 and the air inlet channel 24.

[0031] The courier bag of the present invention can be inflated and then torn open along the tear lines 5 to separate the inflated bags 10 one by one for packaging items. During use, the items are placed in the inner bag 2, and the first bag cap 21 of the inner bag 2 is bonded to the bag body via the first adhesive strip 3, thereby sealing the items in the inner bag 2. Next, the second bag cap 11 of the outer bag 1 is bonded to the bag body via the second adhesive strip 4, thereby enclosing both the items and the inner bag 2.

[0032] The present invention provides a courier bag with both an inner bag 2 and an outer bag 1 that can be sealed, preventing items from falling through the gap between the inner bag 2 and the outer bag 1 and effectively preventing others from viewing the items inside the bag through the gap, thereby enhancing privacy. Furthermore, the present invention utilizes a double adhesive strip for sealing, which improves the flatness of the winding end surface, preventing deviation during winding, improving winding efficiency, and increasing the number of meters of winding. Using a single adhesive strip for sealing can easily cause slippage, making it impossible to wind multiple meters.

[0033] The present invention provides a courier bag, and its manufacturing method comprises the following steps:

[0034] The double-layer film is heat-sealed to form a plurality of heat-sealed lines to form an inflatable bag having a plurality of air storage chambers 22 distributed along a first direction, and the inflatable bag has a first end and a second end located in a second direction that are closed, the first direction being perpendicular to the second direction, the first direction being the direction of the Y-axis, and the second direction being the direction of the X-axis;

[0035] The inflatable bag and a layer of film are overlapped and folded together so that the inflatable bag is placed in the inner layer; the film also has a first end and a second end located in the second direction, the first end of the inflatable bag protrudes from the first end of the film located on the same side as the inflatable bag, and the second end of the inflatable bag protrudes from the first end of the inflatable bag to form a first bag cap 21; the second end of the film protrudes from the first end of the film and the second end of the inflatable bag to form a second bag cap 11;

[0036] Apply glue to the outer surface of the first end and / or the inner surface of the second end of the inflatable bag to form a first adhesive strip 3 extending along the first direction, apply glue to the outer surface of the first end and / or the inner surface of the second end of the film to form a second adhesive strip 4 extending along the first direction, and cover the first adhesive strip 3 and the second adhesive strip 4 with release films respectively;

[0037] The inflatable bag and the film are heat-sealed to form a plurality of heat-sealed edges, the plurality of heat-sealed edges being spaced apart along the first direction, and each heat-sealed edge extending along the second direction, avoiding portions used to form the first bag cap 21 and the second bag cap 11, and also avoiding the bag openings of the inner bag and the outer bag to be formed;

[0038] An easy-tear line 5 is provided on the heat-sealed edge. The easy-tear line 5 extends along the second direction and does not avoid the portion used to form the first bag cap 21 and the second bag cap 11 .

[0039] The above-mentioned inflatable bag is used to form the inner bag 2, and the film is used to form the outer bag 1. An air storage chamber 22 is defined between adjacent heat-sealed lines. The heat-sealed edge forms the connecting side of the inner bag 2 and the outer bag 1, and the tear line 5 is roughly located on the center line of the heat-sealed edge.

[0040] The inflatable bag has a sealed first end and a second end having a central air inlet passage 101 connecting the various air storage chambers 22. One end of the central air inlet passage 101 is provided with an air inlet. A first adhesive strip 3 is provided on the outer surface of the first end of the inflatable bag, and a second adhesive strip 4 is provided on the inner surface of the second end of the film, but the invention is not limited thereto. The film can be colored to enhance privacy.

[0041] The method for making the courier bag further comprises the following steps:

[0042] The portion of the film used to form the second bag cap 11 is folded outward, that is, folded toward the side of the film facing away from the inflatable bag, to expose the portion of the inflatable bag used to form the first bag cap 21. Specifically, the portion of the film used to form the second bag cap 11 is folded away from the bag opening, near the edge of the inner bag opening. The film is then reeled in the first direction, with the portion of the film used to form the second bag cap 11 facing inward. During reeling, the first and second adhesive strips 3 and 4 are arranged parallel to each other, which improves the flatness of the reeled end surface, reduces deviation during reeling, improves reeling efficiency, and increases the number of meters reeled.

[0043] The utility model provides a courier bag, and the unrelated parts are the same as those in the prior art or can be implemented by adopting the prior art.

[0044] The above embodiments are only used to further illustrate a courier bag of the present invention, but the present invention is not limited to the embodiments.
