[0002] The express delivery industry is also continuing to progress and develop as e-shopping forms are developing in a diversified way. During the transportation of express products, the quality of logistics tallying has become uneven with the surge in transportation volume. News of violent tallying by staff is often seen in various news and short video media. Online shopping items are often packaged in various paper turnover boxes for transportation, but the quality of traditional paper packaging boxes is not good and they are easily damaged during transportation, causing buyers and sellers to suffer losses in time and economy to varying degrees. In addition, in order to enhance the connection strength of paper boxes at the corners, merchants often use glue to glue these locations, which not only makes the box body easy to break when opened, but also causes environmental pollution after being discarded. Such packaging products containing glue also need to undergo some processing processes when recycled to remove harmful components, which undoubtedly increases the recycling cycle, cost and difficulty.

[0027] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific diagrams. It should be noted that the terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described here can be implemented in an order other than that illustrated or described here. In addition, the term "including" or "having" and any variation thereof are intended to cover non-exclusive inclusions, for example, a product or device containing a series of components or units is not necessarily limited to those components or units clearly listed, but may include other components or components that are not clearly listed or inherent to these products or devices.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , environmentally friendly plant pulp degradable product packaging box, including a box body, the box body includes a box bottom 101, a top cover 102, a left side 103, a rear side 104, a front side 105, and a rear side 106 ( Figure 4 , Figure 5 The mark on the rear side is actually the rear pad 1061, and this structure is only regarded as the rear side of the double-layer structure). The bottom 101 and the four sides of the box are all double-layer structures to enhance the structural strength, prevent the structure from collapsing during long-term use, and also resist violent operations during logistics sorting.

[0029] The box body is an integrally formed structure, that is, the box bottom 101, the top cover 102, the left side 103, the rear side 104, the front side 105, and the rear side 106 are all formed on the same paperboard, and the paperboard is cut and folded to form the box body.

[0030] The molding cardboard is made of plant pulp cardboard, making the product recyclable and renewable with good environmental protection characteristics.

[0031] The plant pulp paperboard used in the utility model can be prepared according to the following component proportions, and its raw material components include:

[0032]

[0033] Among them, the heat stabilizer can be liquid zinc stabilizer; the plasticizer can be synthetic polyacrylic acid; the antioxidant can be made of triphosphite. The paperboard made by the above-mentioned component ratio has a good natural degradation effect, which can reduce the harm to the environment during use and after disposal. The raw material components are easy to obtain, and the production can follow the manufacturing process of common paperboards. It is simple and convenient, and the cost is effectively reduced from manufacturing to use, which ensures environmental protection effects while enhancing practicality.

[0034] It should be noted that the top cover 102 of the box body is not designed with a double-layer structure. The reason is that: based on the structure of the utility model, a double-layer structure of the top cover will consume more paper and increase the product cost. Since the top of the box body is mostly used for the attachment of information documents such as express delivery orders or other identification labels, after such information documents are set on the box body, the strength of the top structure can be significantly enhanced, so there is no need to further strengthen the top structure of the box body.

[0035] In order to stabilize the top cover after closing and prevent it from collapsing, the utility model can be arranged according to the following structure: In some embodiments, such as Figure 3 , Figure 4As shown, a first ear plate 301 is provided on each side of the top cover 102. When it is covered on the top opening of the inner cavity of the box body surrounded by four side surfaces, it can be attached to the inner surface of the left side surface 103 and the right side surface 104 (the specific attachment position is on the left inner molding plate and the right inner molding plate), while providing support for the top of the box body, it can also effectively enhance the structural strength of the structural box body at the side.

[0036] The utility model is based on the double-layer structure of the left and right sides, and the first ear plates on both sides of the top cover are inserted into the inner cavity of the box body and attached to the inner surfaces of the left and right sides, so that the left and right sides of the box body are further upgraded to a three-layer structure, thereby enhancing the structural strength.

[0037] It should be noted that the size of the first ear plate can be set to be close to the size of the left side / right side, so that it can support the top cover after the top cover is closed, and the first ear plate is not fixed, so that it has a certain swing amplitude in the inner cavity of the box body, so that it can play a certain lining role after the inner cavity of the box body is loaded with internal items, and provide a certain clamping and cushioning effect for the internal items when they move to the left and right directions, and also have a corresponding anti-seismic effect.

[0038] In some preferred embodiments, Figure 3 As shown, the corners of the first ear plate 301 are set as rounded corners, that is, the first ear plate 301 is chamfered at its corners so that its corners have a certain curvature and a rounded structure. This structural setting can facilitate the first ear plate with a larger width to provide guidance when plugging, so that the ear plate is easier to plug into the box body cavity, avoiding the problem of difficult plugging of the right-angle structure (combined with Figure 4 The structure shown, if the first ear plate does not adopt the rounded corners in the structure shown in the figure, but adopts a right-angle structure, then under this setting, although the ear plate structure can be made to fit the inner surface of the top cover to reduce the difficulty of ear plate insertion, this will reduce or even lose the lining function of the ear plate structure. What's worse, its supporting effect on the top cover will also disappear, making the top of the box body easy to collapse and destroying the overall structural strength).

[0039] In order to ensure the structural stability of the front side and the rear side after forming, the utility model can be arranged as follows: In some embodiments, such as Figure 3 , Figure 4 As shown, a second ear plate 302 is connected to each side of the front side 105, and the second ear plate 302 is located in the interlayer of the double-layer structure of the left side 103 and the right side 104 after the box body is formed;

[0040] A third ear plate 303 is connected to each of the two sides of the rear side surface 106 . The third ear plate 303 is located in the interlayer of the double-layer structure of the left side surface 103 and the right side surface 104 after the box body is formed.

[0041] The front and rear sides of the utility model can realize a self-locking structure by setting the second ear plate and the third ear plate in the sandwich structure of the left and right sides, that is, during the molding process of the box body, the structural fixation of the front and rear sides is realized by the setting position of the second ear plate and the third ear plate with the help of the sandwich structure of the left and right sides. Figure 4 , Figure 5 In the structure shown, the states of the second ear plate 302 and the third ear plate 303 before and after being placed in the sandwich structure on the left side and the right side are respectively shown.

[0042] In order to ensure the stability of the front side and the rear side after molding, the utility model can be arranged in the following structure: in some embodiments, a vertical slot can be arranged on the second ear plate and the third ear plate located on the same side (for example, the second ear plate and the third ear plate located on the left side, or the second ear plate and the third ear plate located on the right side), and the slot direction of the second ear plate is opposite to the slot direction of the third ear plate. By arranging the slot structures with opposite opening directions on the second ear plate and the third ear plate, the locking connection structure of the two ear plates is realized, so as to enhance the overall structural strength and prevent looseness.

[0043] It should be noted that the "same side" in this example refers to the same left side or the same right side, that is, the second ear plate and the third ear plate in the interlayer of the double-layer structure on the left side, or the second ear plate and the third ear plate in the interlayer of the double-layer structure on the right side. In order to realize the locking structure between the two ear plates on the same side, the sum of the lengths of the two ear plates can be set to be greater than the length of the left side or the right side on the same side, so that the slots on the two ear plates can be plugged / interlocked with each other.

[0044] like Figure 6 A schematic diagram of a structure of a second ear plate and a third ear plate with slots is shown, wherein the slot 3021 of the second ear plate 302 faces downward, and the slot 3031 of the third ear plate 303 faces upward. Figure 4 , Figure 6 When the box body is formed, the rear side 106 is folded to make it vertical, and then the upward notch 3031 of the third ear plate 303 is made vertical, and then the front side 105 is folded to make the notch 3021 on the second ear plate 302 downward, and then the two ear plates are plugged / clipped along the notch 3031 of the third ear plate 303.

[0045] In order to prevent the top cover from accidentally opening when the articles move in the inner cavity of the box body during transportation, the utility model can be arranged according to the following structure: In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, a front cover plate 107 is disposed on the outer side of the front side 105, and the front cover plate 107 is attached to the front side 105. Figure 4 , Figure 5As shown, the front cover plate 107 is provided with a fourth ear plate 304, and the fourth ear plate 304 is inserted into the sandwich structure of the left side and the right side. Figure 1 , Figure 4 After the fourth ear plate 304 is inserted, it is located between the left side outer plate 1031 and the second ear plate 302. By providing the fourth ear plate, it can be regarded as a structural extension of the cover structure, so that the cover effect can be strengthened, and its cover function can be strengthened to prevent the cover from being easily loosened after closing. During transportation or handling, the items in the box will move upward and lift up the cover. At this time, the cover cannot be opened because it is restricted by the front cover plate and the fourth ear plate, so as to avoid the loss caused by the scattered items inside after the cover is accidentally opened.

[0046] In some preferred embodiments, the corners of the fourth ear plates 304 on both sides of the front cover plate 107 are also rounded to facilitate plugging.

[0047] In some preferred embodiments, Figure 1 , Figure 2 , Figure 3 As shown, the front cover plate 107 is provided with a notch 400, and the notch 400 is located at the lower side of the front cover plate 107. It is convenient to flip up the front cover plate 107 relative to the front side surface that is attached to it and then open the top cover.

[0048] The unfolding and laying structure of the integrated box body of the utility model is arranged as follows: Figure 3 As shown,

[0049] The box bottom 101 is connected upward in sequence to the right outer forming plate 1041 and the right inner forming plate 1042. The two forming plates are folded to form a right side surface with a sandwich structure.

[0050] The box bottom 101 is downwardly connected to the left outer forming plate 1031 and the left inner forming plate 1032 in sequence, and the two are folded to form a left side surface with a sandwich structure;

[0051] Among them, a plug-in plate 202 is provided on the right inner forming plate 1042 and the left inner forming plate 1032, and corresponding plug-in grooves are provided at the connection between the right outer forming plate 1041 and the box bottom 101, and at the connection between the left outer forming plate 1031 and the box bottom 101, so that when forming the sandwich structure of the left side and the right side, the right inner forming plate 1042 and the left inner forming plate 1032 can be fixed after being folded. Figure 2 The plug-in board 202 is shown exposed at the bottom of the box after being plugged and fixed;

[0052] The box bottom 101 is connected to the rear side 106, the top cover 102, and the front cover 107 in sequence to the left;

[0053] The box bottom 101 is connected to the front outer forming plate 1051, the front inner forming plate 1052, the bottom pad 1011, and the rear pad 1061 in sequence to the right, wherein the bottom pad 1011 is padded on the box bottom 101 (specifically, padded on the side surface of the box bottom 101 facing the inner cavity), and the rear pad 1061 is padded on the rear side surface 106 (specifically, padded on the side surface of the rear side surface 106 facing the inner cavity);

[0054] The upper and lower sides of the top cover 102 are respectively connected to a first ear plate 301.

[0055] The upper and lower sides of the front outer forming plate 1051 are respectively connected to a second ear plate 302.

[0056] The upper and lower sides of the rear side surface 106 are respectively connected to a third ear plate 303.

[0057] The upper and lower sides of the front cover plate 107 are respectively connected to a fourth ear plate 304 .

[0058] When the utility model is folded and formed, Figures 4 to 5 conduct:

[0059] like Figure 4 As shown, after the box bottom 101 is placed flat, the structures connected to the front and rear sides thereof are folded in sequence, so that the rear side surface 106 and the front outer forming plate 1051 are vertical, and in this process, the third ear plate 303 and the second ear plate 302 are vertical; in this process, when the third ear plate 303 and the second ear plate 302 adopt a snap-fit ​​structure, the rear side surface 106 is folded first to make the third ear plate 303 vertical first, and then the front outer forming plate 1051 is folded, and the second ear plate 302 is snap-fitted to the slot of the third ear plate 303 along its slot;

[0060] On the basis of the above folding, the outer structure and the inner structure of the left side and the right side are folded in sequence to form a sandwich structure: taking the right side as an example, first fold the right outer forming plate 1041 to make it vertical upward, then fold down the right inner forming plate 1042 to make it vertical, and then plug the plug board 202 on it into the corresponding slot, such as Figure 2 As shown, after plugging, the end of the plug board 202 is exposed outside the box bottom 101. During the folding and forming process of the left and right sides, the second ear plate 302 and the third ear plate 303 are sandwiched in the sandwich structure;

[0061] Then, the front inner forming plate 1052, the bottom pad 1011 and the rear pad 1061 are folded in sequence, so that the front inner forming plate 1052 is attached to the front outer forming plate 1051, the bottom pad 1011 is attached to the box bottom 101, and the rear pad 1061 is attached to the rear side surface 106;

[0062] like Figure 5As shown, the top cover 102 is turned down to cover the top of the inner cavity, and the first ear plates 301 on both sides are inserted into the inner cavity to fit the inner surface of the left side (i.e., the surface of the left inner molding plate 1032 facing the inner cavity) and the inner surface of the right side (i.e., the surface of the right inner molding plate 1042 facing the inner cavity);

[0063] Finally, the front cover plate 107 is folded and attached to the front side surface (ie, the outward surface of the front outer molding plate), and the fourth ear plate 304 is inserted into the sandwich structure of the left side surface and the right side surface.

[0064] In the present invention, in order to strengthen the padding effect of the pad and make it stable after being padded on the respective fitting structures, the following structure can be arranged: Figure 3 As shown, a plug-in board 201 is provided at the connection between the bottom pad and the rear pad, and a plug-in slot corresponding to the plug-in board 201 is provided at the connection between the box bottom 101 and the rear side surface 106.
