In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0039] With the development of the logistics industry, more and more people tend to choose express service to send documents, which is not only efficient and convenient, but also ensures the safety and rapid delivery of documents to the destination. Whether it is a business contract, learning materials or personal certificates, express has become the first choice for people to handle document delivery, greatly improving the efficiency of work and life.

[0040] After picking up the documents, the courier needs to place the documents in the document bag for storage and sealing. However, as shown in the prior art, the sealing edge of the document bag is a straight line, which has the risk of scratching the fingers and can easily cause harm to the courier or the recipient. Figure 1

[0041] To solve the above problems, the first aspect embodiment of the present application provides a document bag, which comprises a first cover 100, a second cover 200 and a first sealing tongue 300 connected with the first cover 100, the first cover 100 and the second cover 200 are oppositely arranged, the first cover 100 and the second cover 200 define an inner cavity and a first opening 110 communicating with the inner cavity, the document can be inserted into the inner cavity through the first opening 110 and accommodated in the inner cavity, and then the first opening 110 is closed to make the document in a relatively sealed state.

[0042] As shown in Figure 2 and Figure 3 , the first cover 100 and the second cover 200 are three-edge sealed, one end forms a first opening 110, and the first sealing tongue 300 is connected with the first cover 100 at the end forming the first opening 110, so that the first sealing tongue 300 can be connected with the second cover 200 after being bent to realize the closure of the first opening 110.

[0043] It should be noted that the document bag is formed by folding an integral paperboard 400, that is, in the production process of the document bag, the paperboard 400 with the first sealing tongue 300, the first cover 100 and the second cover 200 is formed by die cutting, and then folded and bonded to form the document bag.

[0044] ​For the convenience of subsequent description, the side edge of the first closure tongue 300 away from the first cover 100 is named as the first side edge 310. It can be understood that the first closure tongue 300 protrudes from the first cover 100 and the second cover 200 when the file bag is not sealed. Since the file bag is usually made of kraft paper, environmentally friendly paperboard 400 or other materials with certain hardness and toughness to ensure the structural stability and durability of the file bag. Therefore, the first closure tongue 300 often has a certain hardness, as shown in Figure 1 The first side edge 310 is a straight line and relatively sharp, so it is easy to cause cuts to the recipient or the courier.

[0045] In order to reduce the probability of cutting the user, the file bag of the present application optimizes the shape of the first side edge 310. More specifically, the first side edge 310 has a plurality of first protruding sections 311, and each first protruding section 311 can be connected in turn or can be spaced apart. It should be noted that the first protruding section 311 is an arc line, so that the first side edge 310 has a plurality of arc-shaped protrusions. When the user contacts the first side edge 310, the first protruding section 311 will first contact the skin, and the stress of contact with the skin will be dispersed through the smooth outer edge, thereby reducing the probability of cutting the skin. Moreover, the arc-shaped protrusion structure can disperse stress and reduce local stress concentration when stressed, thereby improving the durability and folding resistance of the first closure tongue 300. In addition, the soft arc-shaped edge touch is more comfortable, reducing the discomfort during operation and improving the user's experience.

[0046] In some embodiments, the second cover 200 includes a second side edge 210 close to the first opening 110. It can be understood that during the process of the courier inserting the file into the inner cavity, the hand may also contact the second side edge 210, which has the risk of being scratched by the second side edge 210. Therefore, the shape of the second side edge 210 is also optimized. As shown in Figure 2 and Figure 3 The second side edge 210 has a plurality of second protruding sections 211, and the second protruding section 211 is also an arc line.

[0047] It should be noted that the first side edge 310 can be a wave-shaped structure with alternating arc-shaped protrusions and arc-shaped depressions, as shown in Figure 2 Alternatively, it can also be a wave-shaped structure with a plurality of arc-shaped protrusions connected in turn, as shown in Figure 3 Regardless of which structure, it is beneficial to reduce the stress concentration phenomenon when contacting the skin, thereby reducing the risk of scratching the user.

[0048] It should be noted that reference is made to Figure 6As shown, since the document bag of the present application is formed by folding paperboard 400, multiple paperboards 400 are connected end to end to form a paper roll. The first side 310 of the paperboard 400 is connected to the second side 210 of the previous paperboard 400. In order to avoid adding waste materials during the production and typesetting of the paperboard 400, in the present application, it is preferred to adopt the following method: Figure 2 The wavy structure shown.

[0049] exist Figure 2 In the embodiment, the first side 310 further includes a plurality of first concave sections 312, and the first concave sections 312 and the first convex sections 311 are alternately arranged and sequentially connected to form a wave-shaped structure. Figure 2 As shown, the arc center of the first raised section 311 faces the first cover 100, that is, the arc center of the first raised section 311 is located on the side of the first side 310 closer to the first cover 100. The arc line of the first recessed section 312 faces away from the first cover 100, that is, the arc center of the first recessed section 312 is located on the side of the first side 310 farther from the first cover 100. Along the length of the first side 310, the first raised sections 311 and the first recessed sections 312 are alternately arranged, with the leading end of the first recessed section 312 connected to the trailing end of the preceding first raised section 311, and the trailing end of the first recessed section 312 connected to the leading end of the following first raised section 311, thereby forming an uneven structure on the first side 310.

[0050] By improving the shape of the first side 310 to a wavy shape and smoothly connecting the various arc segments, the sharp corners of the first side 310 in the prior art are avoided. This smooth transition reduces the pressure concentration points when in contact with the skin, making it less likely to cut the skin, greatly reducing the risk of scratching the user.

[0051] In addition, if Figure 2 As shown, the structure of the second side 210 is similar to that of the first side 310, including a second raised section 211 and a second recessed section 212. The arc center of the second raised section 211 faces away from the first sealing tongue 300, that is, the arc center of the second raised section 211 is located on the side of the second side 210 away from the first sealing tongue 300. The arc direction of the second recessed section 212 is toward the first sealing tongue 300, that is, the arc center of the second recessed section 212 is located on the side of the second side 210 close to the first sealing tongue 300.

[0052] It should be noted that the wave-shaped structures on the first side edge 310 and the second side edge 210 are correspondingly arranged. Specifically, along the direction of the file being inserted into the cavity, the first protruding section 311 on the first side edge 310 and the second recessed section 212 on the second side edge 210 are correspondingly arranged, and the first recessed section 312 on the first side edge 310 and the second protruding section 211 on the second side edge 210 are correspondingly arranged. Thus, in the paper roll structure formed by connecting a plurality of paperboards 400, the first side edge 310 and the second side edge 210 with the wave-shaped structure can be formed when the two paperboards 400 are separated by die cutting or indentation at a set position of the paper roll, without the need to process the two side edges respectively to form the wave-shaped structure.

[0053] It can be understood that, in the forming process of the wave-shaped structure described above, the wave-shaped structures between adjacent paperboards 400 can be embedded and filled with each other, so that the paper material will not be wasted, which is beneficial to save production cost.

[0054] In some embodiments, as shown in Figure 2 and Figure 4 , the first gusset 300 and the first cover 100 have a first indentation 411 at the joint. The first indentation 411 can be made by an indentation process, so that the first gusset 300 and the first cover 100 can be more easily bent at the first indentation 411, and then the first gusset 300 can be folded along the first indentation 411 and connected with the second cover 200 to close the first opening 110.

[0055] It can be understood that the first gusset 300 is provided with a connecting part (not shown in the figure) for connecting with the second cover 200. The connecting part can be a tab, and the second cover 200 is provided with a slot, and the tab can be inserted into the slot to realize the connection of the first gusset 300 and the connecting part. Alternatively, the connecting part can also be a glue strip for bonding with the second cover 200. Alternatively, the connecting part can also be a region for applying glue, and after the glue is applied on the connecting part, the connecting part is bonded with the second cover 200.

[0056] Between the connecting part and the first cover 100, the first gusset 300 further comprises a tear strip 320, as shown in Figure 2 and Figure 4As shown, one end of the tearable strip 320 protrudes from the main body of the first closure tongue 300 to provide a force point for the user to pull the tearable strip 320. The two sides of the tearable strip 320 are each provided with a second indentation 412, which can be a break point structure, a pre-set structure that is easy to break or separate, and can be formed by an indentation process. When subjected to external force, such a structure will break along a predetermined path, thereby achieving the functions of opening and separating. After the file bag is filled with files and the first closure tongue 300 is bent to seal the file bag, if the files need to be taken out, the user can pull the tearable strip 320 to separate the first closure tongue 300 from the first cover 100, thereby forming an opening in the file bag to facilitate the taking out of the files.

[0057] The second aspect embodiment of the present application proposes a paperboard 400, which can be folded to form the file bag of the first aspect embodiment. As shown in the unfolded schematic view of the paperboard 400, the paperboard 400 comprises a first main body 410, the two ends of the first main body 410 are respectively formed with a first side edge 310 and a second side edge 210, and the middle part of the first main body 410 is further provided with a third indentation 413 extending parallel to the first side edge 310. The first main body 410 can be folded along the third indentation 413 to form the first cover 100 and the second cover 200. Figure 5

[0058] As shown, the paperboard 400 further comprises two flaps 420, one flap 420 is arranged on each side of the first main body 410, the flaps 420 protrude from the first main body 410 and are arranged corresponding to any one of the first cover 100 or the second cover 200. The junction of the flaps 420 and the first main body 410 has a fourth indentation 414, which is arranged perpendicular to the third indentation 413. The flaps 420 can be folded along the fourth indentation 414 to be connected with the first main body 410. Figure 5

[0059] Specifically, taking the example of the flaps 420 being connected to the two sides of the first cover 100 as shown, after the first main body 410 is folded along the third indentation 413, the flaps 420 can be folded along the fourth indentation 414 to be connected with the second cover 200, thereby realizing the structure of three-edge sealing and one-edge opening of the file bag. In other embodiments, the flaps 420 can also be connected to the two sides of the second cover 200 and can be connected with the first cover 100 after being folded. Based on the foregoing, the first main body 410 is further provided with a first indentation 411, which separates the first cover 100 and the first closure tongue 300. Figure 5

[0060] ​​​In summary, the paperboard 400 forming the file bag is an integrated structure, and the file bag is formed by folding and bonding each part on the first main body 410, so that the process of making the file bag is convenient and fast, and the operation difficulty is low.
