EXPRESS DELIVERY BAG AND STRUCTURAL CONFIGURATION THEREOF

Description

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The present invention relates generally to an express delivery bag, and more particularly to an express delivery bag and its structural configuration that can reduce transportation costs, is suitable for continuous production, can be tracked and theft-proofed during the logistics process.

2. Description of the Prior Art

An express delivery bag is a type of security bag designed to protect products or documents (such as cash, sensitive documents, important credentials, online merchandise, and other items requiring confidentiality and integrity). An express delivery bag includes an outer layer made of plastic material and an adhesive (such as double-sided tape). The adhesive is used to seal the plastic material of the outer layer near the bag opening, thereby closing the bag. Consequently, once the bag is opened, the adhesive leaves noticeable damage or marks on the plastic material near the bag opening, helping to prevent unauthorized individuals from opening the bag and ensuring that its contents remain unaltered or tampered with, thereby increasing confidentiality.

Bubble-type express delivery bags have a bubble layer attached to the inner side of the plastic material outer layer to provide better cushioning performance for protecting items packaged inside the bag, especially for packaging online merchandise. The cushioning performance of the bubble layer prevents damage to online merchandise during transportation caused by collisions. However, the bubble layer of bubble-type express delivery bags contains numerous bubbles to reduce the impact of external forces on the packaged items. These bubbles have a certain volume, leading to increased transportation costs and hindering the application of such products.

In addition, with the booming development of online shopping and the increasing demands of logistics, the lack of traceability and anti-theft measures for the products or documents protected by express delivery bags is also one of the main challenges faced by the industry.

SUMMARY OF THE DISCLOSURE

The present invention provides an express delivery bag and structural configuration thereof that can reduce transportation costs, is suitable for continuous production, can be tracked and theft-proofed during the logistics process, aiming to address the aforementioned issues.

The present invention provides an express delivery bag, which includes an airbag film layer, a plastic bag film layer, and a plurality of perforation lines. The airbag film layer has at least one airbag and a main flow runner, wherein the main flow runner communicates with the at least one airbag, and the main flow runner is adapted to allow an air to be injected into the at least one airbag, changing the at least one airbag from a flat state to an inflated state. The plastic bag film layer wraps the airbag film layer within by folding. The perforation lines run through the plastic bag film layer and the airbag film layer wrapped in the plastic bag film layer, wherein a separable structural configuration is defined between two neighboring ones of the perforation lines.

The present invention also provides a structural configuration of an express delivery bag, wherein the structural configuration includes a plastic bag film layer having a first lateral edge and a second lateral edge corresponding to each other, and an airbag film layer having a third lateral edge and a fourth lateral edge corresponding to each other, wherein the airbag film layer has at least an airbag and a main flow runner. The main flow runner communicates with the at least one airbag, and is adapted to allow an air to enter the at least one airbag, changing the at least one airbag from a flat state to an inflated state. The plastic bag film layer and the airbag film layer are folded together along a folding line, such that the first lateral edge overlaps the third lateral edge to form a first sealing region, and the second lateral edge overlaps the fourth lateral edge to form a second sealing region; the plastic bag film layer and the airbag film layer are sealed through the first sealing region and the second sealing region, and the plastic bag film layer forms an outer bag, while the airbag film layer forms an inner bag; the inner bag has a containing space formed therein, and the inner bag is provided in the outer bag.

In summary, the airbag of the airbag film layer of the express delivery bag and the structural configuration of the present invention can change from the flat state to the inflated state after inflation. Therefore, during transportation, it is not necessary to inflate the airbag, allowing the express delivery bag and the structural configuration of the present invention to remain in the flat state, reducing the volume of the express delivery bag and the structural configuration during transportation, thereby reducing transportation costs. When it is desired to package items using the express delivery bag or the structural configuration of the present invention, the airbag can be inflated to change the express delivery bag and the structural configuration of the present invention to the inflated state, producing a buffering and protective effect. Additionally, the express delivery bag and the structural configuration of the present invention may have an identity authentication component, which can provide identity information, enabling the express delivery bag and the structural configuration to be identified, tracked, and statistically analyzed during the logistics process, or to have anti-theft functionality.

DETAILED DESCRIPTION

The term “non-return valve” mentioned in the text refers to a structure that allows air to pass in only one direction. Its specific structure can be exemplified by the “air valve device” disclosed in Taiwan Patent No. I440590. For the sake of brevity, further elaboration is omitted here.

First Embodiment

Please refer to FIG. 1 through FIG. 6. FIG. 1 depicts a schematic view of a structural configuration 1000′ of an express delivery bag according to the first embodiment of the present invention. FIG. 2 illustrates the appearance and cross-sectional view of an airbag film layer 1 as shown in FIG. 1. FIG. 3 shows a schematic view of the first process step of an express delivery bag 1000 according to the first embodiment of the present invention. FIG. 4 illustrates the second process step of an express delivery bag 1000 according to the first embodiment of the present invention. FIG. 5 depicts the third process step of an express delivery bag 1000 according to the first embodiment of the present invention. Finally, FIG. 6 illustrates the fourth process step of an express delivery bag 1000 according to the first embodiment of the present invention.

As shown in FIGS. 1, 2, 5, and 6, the structural configuration 1000′ of the express delivery bag includes an airbag film layer 1 and a plastic bag film layer 2. The airbag film layer 1 includes at least one airbag 10 and a main flow runner 11. The main flow runner 11 connects to at least one airbag 10, and it is used to supply air into at least one airbag 10, causing the airbag to change from a flat state to an inflated state. In this embodiment, the airbag film layer 1 has multiple airbags 10, but the present invention is not limited to this; for example, the airbag film layer 1 can also have only one airbag 10, depending on actual requirements.

Below, the process of the express delivery bag 1000 and its structural configuration 1000′ according to the first embodiment of the present invention is explained. As shown in FIG. 3, firstly, the plastic bag film layer 2 is provided. The plastic bag film layer 2 is pulled out from a plastic bag film layer reel 80 and passed through a set of tension rollers 82 to keep it flat. Next, the airbag film layer 1 is overlaid onto the plastic bag film layer 2. The airbag film layer 1 is pulled out from an airbag film layer reel 90 and similarly passed through a set of tension rollers 92 to keep it flat. The airbag film layer 1, after passing through the tension rollers 92, changes direction at a turning roller 94, and then passes simultaneously with the plastic bag film layer 2 through a set of overlapping rollers 84, thereby completing the overlapping of the plastic bag film layer 2 and the airbag film layer 1.

Next, as shown in FIG. 4, the overlapped plastic bag film layer 2 and airbag film layer 1 pass through a triangular folding piece 100. As they pass through this folding piece 100, the overlapped plastic bag film layer 2 and airbag film layer 1 fold along a folding line FL together. At this point, the plastic bag film layer 2 folds over the airbag film layer 1. Furthermore, another set of tension rollers 101 is used to keep the folded plastic bag film layer 2 and airbag film layer 1 flat, and a set of pressing rollers 102 is used to make the folded plastic bag film layer 2 and airbag film layer 1 adhere more tightly.

As shown in FIG. 3, the plastic bag film layer 2 has a first top edge 20 and a second top edge 21 corresponding to each other. The airbag film layer 1 has a third top edge 15 and a fourth top edge 16 corresponding to each other. As shown in FIG. 5, after the plastic bag film layer 2 and airbag film layer 1 are folded together along the folding line FL by the folding piece 100, the second top edge 21 of the plastic bag film layer 2 is located between the first top edge 20 of the plastic bag film layer 2 and the folding line FL, while the fourth top edge 16 of the airbag film layer 1 is located between the third top edge 15 of the airbag film layer 1 and the folding line FL. The third top edge 15 of the airbag film layer 1 is positioned between the first top edge 20 and the second top edge 21 of the plastic bag film layer 2, and the main flow runner 11 is located between the third top edge 15 and the folding line FL.

As shown in FIG. 5, after the plastic bag film layer 2 and the airbag film layer 1 are folded along the folding line FL, the present invention utilizes a sealing device 103 and a perforation device 104 to generate multiple edge-sealing structures 4 and multiple perforation lines 3 respectively. Each edge-sealing structure 4 is used to secure the plastic bag film layer 2 and the airbag film layer 1 together, and each perforation line 3 corresponds to one of the multiple edge-sealing structures 4. Each perforation line 3 is set through the plastic bag film layer 2 and extends through the airbag film layer 1 wrapped inside the plastic bag film layer 2, connecting the first top edge 20 of the plastic bag film layer 2 with the folding line FL. In this embodiment, the sealing device 103 can be, for example, a heat sealing device, and the perforation device 104 can be, for example, a perforation cutting machine, but the present invention is not limited to these. Additionally, when the plastic bag film layer 2 and the airbag film layer 1 are folded along the folding line FL and the edge-sealing structures 4 and perforation lines 3 are generated, the plastic bag film layer 2 and the airbag film layer 1 can form an express delivery bag 1000.

When the plastic bag film layer 2 and the airbag film layer 1 form an express delivery bag 1000, the express delivery bag 1000 is not yet inflated and remains in the flat state, which significantly reduces the occupied volume of the express delivery bag 1000. Furthermore, the express delivery bag 1000 in the flat state can be rolled up into an express delivery bag reel 1001, as shown in FIG. 6. Similarly, the express delivery bag reel 1001, due to the express delivery bag 1000 being in the flat state, significantly reduces the occupied volume, thereby facilitating the transportation of the express delivery bag reel 1001 and reducing the transportation costs of both the express delivery bag reel 1001 and the express delivery bag 1000.

Furthermore, two neighboring perforation lines 3 can define a structural configuration 1000′ of an express delivery bag in between, as shown in FIG. 1, where the edge-sealing structures 4 form the sides of the structural configuration 1000′, and the folding line FL forms the bottom thereof. The plastic bag film layer 2 forms the outer bag of the structural configuration 1000′, while the airbag film layer 1 forms the inner bag. The inner bag forms a containing space, positioned within the outer bag. In summary, the structural configuration 1000′ is a double-layered bag, with the outer bag formed by the plastic bag film layer 2 and the inner bag formed by the airbag film layer 1. Both the outer bag and the inner bag of the structural configuration 1000′ have the folding line FL as the bottom and the edge-sealing structures 4 as the sides.

It is worth mentioning that the perforation lines 3 of the express delivery bag 1000 connect the first top edge 20 of the plastic bag film layer 2 to the folding line FL, thus linking the top and bottom edges of the express delivery bag 1000. Since the perforation lines 3 penetrate through both the plastic bag film layer 2 and the airbag film layer 1, they weaken the structural integrity of both layers. Consequently, when one side of the express delivery bag 1000 is subjected to force, the plastic bag film layer 2 and the airbag film layer 1 are most likely to break apart at the location of the perforation line 3 (where the structural strength is weaker), leading to the separation of the structural configuration 1000′ from the express delivery bag 1000. In other words, the express delivery bag 1000 of the present invention is a continuous bag containing multiple structural configurations 1000′, each of which is delineated by perforation lines 3 and can be torn off from the continuous bag independently to form a standalone bag. After the structural configuration 1000′ is torn off from the continuous bag by the perforation line 3, the airbag film layer 1 of the structural configuration 1000′ can form a third lateral edge 17 and a fourth lateral edge 18 corresponding to each other, while the plastic bag film layer 2 can form a first lateral edge 22 and a second lateral edge 23, which also correspond to each other.

In this embodiment, each edge-sealing structure 4 is in a U-shaped configuration, meaning each edge-sealing structure 4 includes a left-edge sealing structure 40, a right-edge sealing structure 41, and an up-edge sealing structure 42. The left-edge sealing structure 40 is located on one side of one of the multiple perforation lines 3, while the right-edge sealing structure 41 is located on the other side of another perforation line 3. In other words, the left-edge sealing structure 40 and the right-edge sealing structure 41 are positioned on opposite sides of their corresponding perforation lines 3. The up-edge sealing structure 42 is located between the left-edge sealing structure 40 and the right-edge sealing structure 41. In this embodiment, the up-edge sealing structure 42 connects the left-edge sealing structure 40 and the right-edge sealing structure 41.

Please refer to FIG. 5 through FIG. 7. FIG. 7 depicts a schematic view of the express delivery bag 1000 in the process of inflation according to the first embodiment of the present invention. In this embodiment, the airbag film layer 1 also includes multiple secondary flow runners 12. The number of secondary flow runners 12 corresponds to the number of airbags 10, and each secondary flow runner 12 connects the main flow runner 11 to one of the airbags 10. In this embodiment, the inflation device C also includes a heat sealing device A, a cutting device B, a nozzle C′, and a driving roller D. The nozzle C′ is used to spray air G, and the driving roller D is used to propel the express delivery bag 1000. Due to the perspective, FIG. 7 only depicts one roller, but in practice, those skilled in the art should understand that the driving roller D is composed of a pair of upper and lower rollers. By gripping and pulling with the upper and lower rollers, the express delivery bag 1000 is moved in the direction indicated by the arrow E in FIG. 7.

Continuing from the above, the express delivery bag 1000 is formed by driving the plastic bag film layer 2 and the airbag film layer 1 to overlap with each other using rollers. Then, they are folded by the folding piece 100, and finally, the overlapped and folded plastic bag film layer 2 and airbag film layer 1 are sealed and cut separately by the sealing device 103 and the cutting device 104. Therefore, the width of each structural configuration 1000′ is determined by the activation cycle of the sealing device 103 and the cutting device 104, along with the speed of the rollers. That is, at the same roller speed, when the activation cycle of the sealing device 103 and the cutting device 104 is shorter, the width of each structural configuration 1000′ is narrower; when the activation cycle of the sealing device 103 and the cutting device 104 is longer, the width of each structural configuration 1000′ is wider.

In practice, since the airbags 10 and secondary flow runners 12 on the airbag film layer 1 are evenly distributed, the positions of the perforation lines 3 generated by the cutting device 104 when the overlapped and folded plastic bag film layer 2 and airbag film layer 1 pass through it vary depending on the actual width requirements of the structural configuration 1000′. The positions of the perforation lines 3 mentioned above can include the following three types:

• • Position One: located between the airbags 10 and the secondary flow runners 12 (as illustrated in the diagrams of this embodiment);
  • Position Two: located only between the airbags 10 but not on the secondary flow runners 12; and
  • Position Three: located between the airbags 10 and the secondary flow runners 12.

Continuing from the above, since the perforation lines 3 penetrate both the plastic bag film layer 2 and the airbag film layer 1, when one perforation line 3 is located at positions such as Position One and Position Two, the main flow runner 11, secondary flow runner 12, and airbag 10 can communicate with the outside of the express delivery bag 1000 through the perforation line 3. Therefore, the up-edge sealing structure 42 of the edge-sealing structure 4 is adjacent to the bottom edge 111 of the main flow runner 11 on the airbag film layer 1, and the up-edge sealing structure 42 connects the left-edge sealing structure 40 and the right-edge sealing structure 41. In this way, the up-edge sealing structure 42, left-edge sealing structure 40, and right-edge sealing structure 41 of the edge-sealing structure 4 can prevent the air G from entering the secondary flow runner 12 and the airbag 10 punctured by the perforation line 3, and from escaping to the outside of the express delivery bag 1000 through the perforation lines 3 on the secondary flow runner 12 and the airbag 10.

In the present invention, the position of the up-edge sealing structure 42 of the edge-sealing structure 4 is not limited to the diagram illustrated in this embodiment. For example, the up-edge sealing structure 42 can also be positioned between the bottom edge 111 and a top edge 110 of the main flow runner 11 on the airbag film layer 1. Additionally, the up-edge sealing structure 42 connects the left-edge sealing structure 40 and the right-edge sealing structure 41. In this way, the up-edge sealing structure 42, left-edge sealing structure 40, and right-edge sealing structure 41 of the edge-sealing structure 4 can also prevent the air G from entering the secondary flow runner 12 and the airbag 10 punctured by the perforation line 3, and from escaping to the outside of the express delivery bag 1000 through the perforation line 3 on the secondary flow runner 12 and the airbag 10. In other words, the structural design where the left-edge sealing structure 40, right-edge sealing structure 41, and up-edge sealing structure 42 do not completely seal the main flow runner 11 and can block the air G from entering the secondary flow runner 12 and the airbag 10 punctured by the perforation line 3, thereby preventing communication with the outside of the express delivery bag 1000 through the perforation line 3 on the secondary flow runner 12 and the airbag 10, falls within the scope of protection of the present invention.

As shown in FIG. 7, when the express delivery bag 1000 is driven by the driving roller D and moves in the direction of the arrow E towards the nozzle C′ of the inflation device C to enter the main flow runner 11, the air G sprayed out by the nozzle C′ of the inflation device C can enter the main flow runner 11. Then, it is directed through each secondary flow runner 12 into the corresponding airbag 10, causing the airbag 10 to change from the flat state to the inflated state. Next, as the express delivery bag 1000 continues to be driven by the driving roller D along the arrow E, the cutting device B can puncture the main flow runner 11. This allows the nozzle C′ to continue entering the main flow runner 11 so that subsequent express delivery bags 1000 driven out by the driving roller D from the express delivery bag reel 1001 can be inflated. Additionally, after the inflation device C inflates the airbag 10, transforming it from the flat state to the inflated state, the driving roller D continues to move the inflated airbag 10 towards the heat sealing device A. This action causes the secondary flow runner 12 to pass through the heat sealing device A, where the heat sealing device A seals the secondary flow runner 12 thermally. Consequently, the secondary flow runner 12 can be sealed by the heat sealing device A to prevent the air G injected into the airbag 10 from escaping through the secondary flow runner 12. It's worth mentioning that in other embodiments, the heat sealing device A can also be used to seal the airbag 10 to prevent the air G injected into the airbag 10 from escaping through the secondary flow runner 12. Ideally, the heat sealing device A seals the airbag 10 near the secondary flow runner 12, effectively preventing the air G from escaping through the secondary flow runner 12 or the airbag 10. This sealing mechanism aims to prevent the dissipation of air G injected into the airbag 10, ensuring its inflation.

Second Embodiment

Please refer to FIG. 8, which depicts a schematic view of an express delivery bag 2000 and its structural configuration 2000′ during the inflation process in the second embodiment of the present invention. The main difference between the express delivery bag 2000 and its structural configuration 2000′ and the previously described express delivery bag 1000 and its structural configuration 1000′ lies in that at least one of the plurality of edge-sealing structures 4′ of the express delivery bag 2000 is a ribbon-shaped edge-sealing structure. The top edge 43 of the ribbon-shaped edge-sealing structure is adjacent to the bottom edge 111 of the main flow runner 11 or located between the bottom edge 111 and a top edge 110 of the main flow runner 11. In other words, the ribbon-shaped edge-sealing structure does not completely seal the main flow runner 11, falling within the scope of protection of the present invention. In this embodiment, all edge-sealing structures 4′ are ribbon-shaped edge-sealing structures, but the present invention is not limited to this. That is, the design where one or more edge-sealing structures 4′ are ribbon-shaped edge-sealing structures also falls within the scope of protection of the present invention. Components with the same reference numerals as those in the previous embodiment have the same structure. To avoid redundancy, their description is omitted here.

Third Embodiment

Please refer to FIG. 9, which illustrates a schematic view of an express delivery bag 3000 and its structural configuration 3000′ during the inflation process in the third embodiment of the present invention. The main difference between the express delivery bag 3000 and its structural configuration 3000′ and the previously described express delivery bag 1000 and its structural configuration 1000′ lies in that the plurality of airbags 10′ in the express delivery bag 3000 are cylindrical. Components with the same reference numerals as those in the previous embodiments have the same structure. To avoid redundancy, their description is omitted here.

Fourth Embodiment

Please refer to FIG. 10, which illustrates a schematic view of an express delivery bag 4000 and its structural configuration 4000′ during the inflation process in the fourth embodiment of the present invention. The main difference between the express delivery bag 4000 and its structural configuration 4000′ and the previously described express delivery bag 1000 and its structural configuration 1000′ lies in that the airbag film layer 1 of express delivery bag 4000 additionally includes multiple secondary non-return valves 14. The plurality of secondary non-return valves 14 correspond to one of the multiple airbags 10 and one of the multiple secondary flow runners 12. The plurality of secondary non-return valves 14 are installed in one of the multiple secondary flow runners 12. The secondary non-return valves 14 are used to prevent the air G entering the airbag 10 from escaping through the secondary flow runner 12. In this embodiment, the airbag film layer 1 contains multiple secondary non-return valves 14, but the present invention is not limited thereto. The design of one or more secondary non-return valves 14 is within the scope of protection of the present invention. Components with the same reference numerals as those in the previous embodiments have the same structure. To avoid redundancy, their description is omitted here.

Fifth Embodiment

Please refer to FIG. 11A, which illustrates a schematic view of an express delivery bag 5000 and its structural configuration 5000′ in the fifth embodiment of the present invention. The main difference between express delivery bag 5000 and its structural configuration 5000′ and the previously described express delivery bag 1000 and its structural configuration 1000′ lies in the sealing structure. Express delivery bag 5000 is sealed by sealing device 103 to form a first lateral-edge sealing structure 61, a second lateral-edge sealing structure 71, and a top edge sealing structure 81. The top edge sealing structure 81 is adjacent to the bottom edge 111 of the main flow runner 11. One end of the first lateral-edge sealing structure 61 is connected to the top edge sealing structure 81 or located between the bottom edge 111 and the top edge 110 of the main flow runner 11 to form an air inlet 112 at one end 113 of the main flow runner 11. One end of the second lateral-edge sealing structure 71 is connected to the top edge 110 of the main flow runner 11, the top edge of the airbag film layer 1 (i.e., the third top edge 15), or one of the top edges of the plastic bag film layer 2 (i.e., the first top edge 20) to seal the other end 114 of the main flow runner 11. Additionally, express delivery bag 5000 includes multiple secondary non-return valves 14. The plurality of secondary non-return valves 14 correspond to one of the multiple airbags 10 and one of the multiple secondary flow runners 12. The plurality of secondary non-return valves 14 are installed in one of the multiple secondary flow runners 12. In this embodiment, the airbag film layer 1 contains multiple secondary non-return valves 14, but the present invention is not limited thereto. The design of one or more secondary non-return valves 14 is within the scope of protection of the present invention.

Furthermore, express delivery bag 5000 forms a continuous bag structure, which is then cut by a cutting device 105 between the first lateral-edge sealing structure 61 and the second lateral-edge sealing structure 71. The cut express delivery bag 5000 can thereby form independent bag structures (i.e., the structural configuration 5000′). The top edge sealing structure 81, which is cut, is thus divided into two parts. Consequently, the plastic bag film layer 2 of the structural configuration 5000′ can have a first lateral edge 22 and a second lateral edge 23, which correspond to each other; and the airbag film layer 1 of the structural configuration 5000′ can have a third lateral edge 17 and a fourth lateral edge 18, which correspond to each other.

Furthermore, the third lateral edge 17 of the airbag film layer 1 of the structural configuration 5000′ overlaps with the first lateral edge 22 of the plastic bag film layer 2. After being sealed by the sealing device 103 and cut by the cutting device 105, this overlap forms a first sealing region 6. The first sealing region 6 includes a first top-edge sealing structure 60 (part of the cut top-edge sealing structure 81) and a first lateral-edge sealing structure 61. The first top-edge sealing structure 60 is adjacent to the bottom edge 111 of the main flow runner 11, and the end of the first lateral-edge sealing structure 61 is connected to the top-edge sealing structure 81 or located between the bottom edge 111 and the top edge 110 of the main flow runner 11, creating an air inlet 112 at the end 113 of the main flow runner 11. Similarly, the fourth lateral edge 18 of the airbag film layer 1 overlaps with the second lateral edge 23 of the plastic bag film layer 2. After being sealed by the sealing device 103 and cut by the cutting device 105, this overlap forms a second sealing region 7. The second sealing region 7 includes a second top-edge sealing structure 70 (another part of the cut top-edge sealing structure 81) and a second lateral-edge sealing structure 71. The second top-edge sealing structure 70 is adjacent to the bottom edge 111 of the main flow runner 11, and the end of the second lateral-edge sealing structure 71 is connected to the top edge 110 of the main flow runner 11, the top edge of the airbag film layer 1, or the top edge of the plastic bag film layer 2, thus sealing the other end 114 of the main flow runner 11.

Continuing from the above, the plastic bag film layer 2 of the structural configuration 5000′ forms an outer bag, while the airbag film layer 1 forms an inner bag. The inner bag contains a containing space for storing/packaging an item, and it is placed inside the outer bag. When the inner bag (i.e., the airbag film layer 1 of the structural configuration 5000′) is inflated, the air G can enter the main flow runner 11 through the air inlet 112 at the end 113 of the main flow runner 11. Since the other end 114 of the main flow runner 11 is sealed by the second lateral-edge sealing structure 71, the air G entering the main flow runner 11 cannot escape from the other end 114 of the main flow runner 11. Instead, it enters the corresponding airbag 10 through the secondary flow runners 12, causing the airbag 10 to inflate.

In this way, the inner bag in the inflated state (i.e., the airbag film layer 1 of the structural configuration 5000′) can provide cushioning and protection for the item inside. It's worth noting that the secondary non-return valves 14 located in the secondary flow runners 12 prevent the air from escaping from the secondary flow runners 12 after inflating the airbag 10, allowing the airbag 10 to maintain the inflated state. Additionally, the outer bag (i.e., the plastic bag film layer 2 of the structural configuration 5000′) can be made of plastic material. When the outer bag is opened, any visible damage or signs of tampering on the plastic material of the outer bag can be easily detected. This helps prevent unauthorized access to the bag and ensures that the item inside remains unaltered or unchanged.

Furthermore, please refer to FIG. 11B, which illustrates another embodiment of the present invention, an express delivery bag 5000″ and its structural configuration 5000′. The main difference between express delivery bag 5000″ and express delivery bag 5000 lies in the manufacturing process. Express delivery bag 5000″ does not use a cutting device 105 but instead employs a perforation device 104. This means that adjacent pairs of structural configurations 5000′ in express delivery bag 5000″ are separated by perforation lines 3 created by the perforation device 104. As a result, the adjacent structural configurations 5000′ in express delivery bag 5000″ remain connected by perforation lines 3. When one side of express delivery bag 5000″ is subjected to force, it is most likely to tear apart at the location of the perforation lines 3 (i.e., the weakest structural points), causing the structural configurations 5000′ to be torn away from express delivery bag 5000″. Therefore, in this embodiment, express delivery bag 5000″ is a continuous bag body containing multiple structural configurations 5000′, each separated by perforation lines 3. These multiple structural configurations 5000′ are delineated by perforation lines 3 and can be torn away from the continuous bag body formed by express delivery bag 5000″ along the perforation lines 3, thus becoming independent bags.

Sixth Embodiment

Please refer to FIG. 12, which illustrates a schematic view of the sixth embodiment of the present invention, a structural configuration 6000′. The main difference between structural configuration 6000′ and the previously described structural configuration 5000′ lies in the absence of secondary non-return valves in the secondary flow runners 12 of structural configuration 6000′. Instead, structural configuration 6000′ includes a main non-return valve 13. The main non-return valve 13 is positioned at the air inlet 112 at the end 113 of the main flow runner 11. It functions to prevent the air G entering the airbag 10 from escaping through the air inlet 112. Components with the same reference numbers as the previous embodiments have identical structures. To avoid repetition, further elaboration is omitted here.

Seventh Embodiment

Please refer to FIG. 13, which depicts a schematic view of the seventh embodiment of the present invention, an express delivery bag 7000 and its structural configuration 7000′. The main difference between express delivery bag 7000 and its structural configuration 7000′ and the previously described structural configuration 6000′ lies in the configuration of the cut-out structural configuration 7000′. The first sealing region 6′ of the structural configuration 7000′ includes a first top-edge sealing structure 60 and a first lateral-edge sealing structure 61′. The first top-edge sealing structure 60 is adjacent to the bottom edge 111 of the main flow runner 11, while one end of the first lateral-edge sealing structure 61′ is connected to the top edge 110 of the main flow runner 11, the top edge (third top edge 15) of the airbag film layer 1, or the top edge (first top edge 20) of the plastic bag film layer 2, thereby sealing one end 113 of the main flow runner 11. The second sealing region 7 of the structural configuration 7000′ includes a second top-edge sealing structure 70 and a second lateral-edge sealing structure 71. The second top-edge sealing structure 70 is adjacent to the bottom edge 111 of the main flow runner 11, while one end of the second lateral-edge sealing structure 71 is connected to the top edge 110 of the main flow runner 11, the top edge (third top edge 15) of the airbag film layer 1, or the top edge (first top edge 20) of the plastic bag film layer 2, thereby sealing the other end 114 of the main flow runner 11.

The airbag film layer 1 also includes an air inlet 112′, which communicates with the main flow runner 11 and is located between the end 113 and the other end 114 of the main flow runner 11 in the express delivery bag 7000. This means that the air inlet 112′ of the express delivery bag 7000 is not positioned at either end 113 or the other end 114 of the main flow runner 11. Additionally, the structural configuration 7000′ includes a main non-return valve 13, which is positioned at the air inlet 112′. Therefore, the main non-return valve 13 of the structural configuration 7000′ is also not positioned at either end 113 or the other end 114 of the main flow runner 11. The main non-return valve 13 is used to prevent the air G from entering the airbag 10 from the air inlet 112′. The components in this embodiment share the same identifiers as those in the previous embodiments and have the same structure; therefore, I won't elaborate on them further for the sake of brevity.

Eighth Embodiment

Please refer to FIG. 14, which illustrates an express delivery bag 8000 and its structural configuration 8000′ in the eighth embodiment of the present invention. The main difference between express delivery bag 8000 and its structural configuration 8000′ and the previously described express delivery bag 1000 and its structural configuration 1000′ lies in the fact that the airbag film layer 1′ of express delivery bag 8000 and its structural configuration 8000′ additionally has a film layer perforation line 19. The film layer perforation line 19 penetrates the airbag film layer 1′ and is located adjacent to one of the edge-sealing structures 4, connecting the third top edge 15 with the fourth top edge 16.

When the airbag film layer 1′ transitions from the flat state to the inflated state, the thickness of each airbag 10 increases due to inflation, causing a reduction in the width of each airbag 10. In practice, the width of each airbag 10 in the inflated state decreases by approximately 10%-30% compared to the width in the flat state.

Furthermore, since the airbag film layer 1′ and the plastic bag film layer 2 are fixedly joined by the edge-sealing structure 4, when the width of the airbag 10 decreases due to inflation while the plastic bag film layer 2 remains unchanged, the reduction in the width of the airbag 10 causes the airbag film layer 1′ to pull the plastic bag film layer 2 inward. As mentioned above, the film layer perforation line 19 creates a weaker structural point in the airbag film layer 1′ at the location of the film layer perforation line 19. Therefore, when the width of the airbag 10 decreases, causing the airbag film layer 1′ to pull the plastic bag film layer 2 inward, the airbag film layer 1′ may detach from the plastic bag film layer 2 at the location of the film layer perforation line 19 either by self-separation or by external force pulling. In this way, after the separation between the plastic bag film layer 2 and the airbag film layer 1′, the plastic bag film layer 2 can remain unchanged in appearance (e.g., without wrinkles) despite being pulled, thus maintaining the appearance of the express delivery bag 8000 and its structural configuration 8000′. Components in this embodiment share the same labels as in the previous embodiments and possess identical structures, and for brevity, these are not reiterated here.

Please refer to FIG. 15, which illustrates an embodiment of the present invention, an express delivery bag 9000 and its structural configuration 9000′. The main difference between express delivery bag 9000 and its structural configuration 9000′ and the previously described express delivery bag 1000 and its structural configuration 1000′ lies in the fact that the containing space of the inner bag formed by the airbag film layer 1 is used to accommodate an object O (e.g., a book, a parcel), and an identity authentication component F is attached to object O. Consequently, when object O is placed inside the containing space of the inner bag, the identity authentication component F, along with object O, is placed inside the inner bag, enabling the express delivery bag 9000 and its structural configuration 9000′ to be identified, tracked, and statistically analyzed during the logistics process. Alternatively, the identity authentication component F can also provide anti-theft functionality. For example, when an express delivery bag 9000 and its structural configuration 9000′ with an identity authentication component F that has not been deactivated passes through a reader, the reader may issue a warning, thereby achieving anti-theft functionality. Additionally, because the identity authentication component F assigns an identity to the express delivery bag 9000 and its structural configuration 9000′, it is possible to predefine in the management system whether the identified identity is allowed to pass or not. Consequently, when an express delivery bag 9000 and its structural configuration 9000′ with an identity authentication component F that has been permitted to pass through the reader, the management system, upon reading the returned identity, determines that the identity is allowed to pass, and thus the reader does not issue a warning. Conversely, when an express delivery bag 9000 and its structural configuration 9000′ with an identity authentication component F that has not been permitted to pass through the reader, the management system, upon reading the returned identity, determines that the identity is not allowed to pass, and thus the reader issues a warning, thereby achieving anti-theft functionality.

As shown in FIG. 15, the plastic bag film layer 2 has a first surface 24 facing the airbag film layer 1, and the first surface 24 has a first binding region 240. The airbag film layer 1 has a second surface 1A facing the plastic bag film layer 2, and the second surface 1A has a second binding region 1A0. An area of the first binding region 240 is smaller than the area of the first surface 24 of the plastic bag film layer 2, and an area of the second binding region 1A0 is smaller than the area of the second surface 1A of the airbag film layer 1. Additionally, the first binding region 240 and the second binding region 1A0 can be adhered to each other by an adhesive.

Please refer to FIG. 16, which illustrates an embodiment of the express delivery bag 10000 and its structural configuration 10000′. The main difference between the express delivery bag 10000 and its structure 10000′ compared to the previously described express delivery bag 1000 and its structure 1000′ lies in the inclusion of an identity authentication component F. The identity authentication component F is positioned on either the airbag film layer 1 or the plastic bag film layer 2. In this embodiment, the identity authentication component F is positioned on the outer side of the plastic bag film layer 2 (i.e., the outer bag), but the invention is not limited to this configuration. For example, the identity authentication component F could also be positioned on the inner side of the plastic bag film layer 2 (i.e., the outer bag) opposite to the outer side, or on the outer side of the airbag film layer 1 (i.e., the inner bag), or on the inner side of the airbag film layer 1 opposite to the outer side, depending on the specific requirements.

In practice, the identity authentication component F can be a wireless radio frequency tag, a two-dimensional code (QR code), or a one-dimensional code (bar code). The identity authentication component F can be attached to the airbag film layer 1 or the plastic bag film layer 2, or placed inside the inner bag containing space, or positioned between the airbag film layer 1 and the plastic bag film layer 2, for example, within the space between them. In this way, the identity authentication component F can provide identity information, enabling the express delivery bag 10000 and its structural configuration 10000′ to be identified, tracked, and accounted for during the logistics process. Additionally, the identity authentication component F can serve an anti-theft function. For instance, when an express delivery bag 10000 and its structural configuration 10000′ containing an identity authentication component F with active identification features pass through a reader, the reader can issue a warning, thereby serving an anti-theft function. Alternatively, because the identity authentication component F assigns a unique identity to the express delivery bag 10000 and its structural configuration 10000′, the management system can preset the allowed or disallowed status based on this identity. Consequently, when an express delivery bag 10000 and its structural configuration 10000′ with an identity authentication component F that allows passage pass through a reader, the management system, upon reading the returned identity, determines the identity as permitted, and thus, the reader does not issue a warning. Conversely, when an express delivery bag 10000 and its structural configuration 10000′ lacking an identity authentication component F that allows passage pass through a reader, the management system, upon reading the returned identity, determines the identity as not permitted, and thus, the reader issues a warning, thereby serving an anti-theft function.

Please refer to FIG. 17. It illustrates an express delivery bag 11000 and its structural configuration 11000′, representing the eleventh embodiment of the present invention. Unlike the previous embodiments, based on practical usage requirements, object O can optionally be accommodated between the outer bag and the inner bag. In this case, when object O is accommodated between the outer bag and the inner bag, the identity authentication component F, along with object O, is placed between the outer bag and the inner bag, enabling the express delivery bag 11000 and its structural configuration 11000′ to be identified, tracked, and accounted for during the logistics process. Alternatively, the identity authentication component F can also serve an anti-theft function. For instance, when an express delivery bag 11000 and its structural configuration 11000′ containing an identity authentication component F with active identification features pass through a reader, the reader can issue a warning, thereby serving an anti-theft function. Or, because the identity authentication component F assigns a unique identity to the express delivery bag 11000 and its structural configuration 11000′, the management system can preset the allowed or disallowed status based on this identity. Consequently, when an express delivery bag 11000 and its structural configuration 11000′ with an identity authentication component F that allows passage pass through a reader, the management system, upon reading the returned identity, determines the identity as permitted, and thus, the reader does not issue a warning. Conversely, when an express delivery bag 11000 and its structural configuration 11000′ lacking an identity authentication component F that allows passage pass through a reader, the management system, upon reading the returned identity, determines the identity as not permitted, and thus, the reader issues a warning, thereby serving an anti-theft function.

Compared to previous technologies, the airbag film layer compartments of the express delivery bag and structural configuration of the present invention can change from the flat state to the inflated state after inflation. Therefore, during transportation, it is possible to keep the compartments uninflated, maintaining the express delivery bag and structural configuration in the flat state, thereby reducing the volume of the express delivery bag and structural configuration during transport and lowering transportation costs. When it is desired to package items using the express delivery bag or structural configuration of the present invention, the compartments can then be inflated to transition the express delivery bag and structural configuration to the inflated state, providing cushioning and protection. Additionally, the express delivery bag and structural configuration of the present invention feature an identity authentication component. This identity authentication component can provide identity information, enabling the express delivery bag and its structure to be identified, tracked, and accounted for during the logistics process, or it can serve an anti-theft function.

It should be realized that the above description is only some preferred embodiments of the present invention and should not be deemed as limitations of implementing the present invention. All substantially equivalent variations and modifications which employ the concepts disclosed in this specification and the appended claims should fall within the scope of the present invention.
