[0032] It should also be noted that unless otherwise clearly specified and limited, the terms "set", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0033] Please refer to Figure 1As shown in the figure, an embodiment of the present application provides a fully paper packaging box, including: a paper box 10, the paper box 10 forms a receiving cavity 10A, a lining is arranged in the receiving cavity 10A for assembling products, and the paper box 10 and the lining are respectively formed by folding; self-locking structures are integrally arranged on the paper box 10 and the lining respectively, and the folding joints of the paper box 10 and the lining are respectively buckled and connected through their respective self-locking structures.

[0034] The paper box 10 forms a receiving cavity 10A. For example, in the present application, the first lining 20 and the second lining 30 are placed in the receiving cavity 10A as an example, and the first lining 20 and the second lining 30 can be located on the same plane; in other embodiments, the number of linings in the receiving cavity 10A can also be one, three or more than three, and when the volume of the receiving cavity 10A is large enough, multiple linings can also be placed in multiple layers, which is specifically set according to actual needs.

[0035] In addition, in the example of the application, there are two first linings 20, the two first linings 20 are arranged oppositely, and one second lining 30 is located at one end of the two first linings 20; the two first linings 20 are oppositely enclosed to limit and assemble the product; and one second lining 30 can be used to assemble the product.

[0036] The first lining 20 and the second lining 30 can also be presented in other combinations, as long as they can be placed in the receiving cavity 10A without interfering with each other.

[0037] In addition, for the fully paper packaging box provided by the embodiment of the present application, both the paper box 10 and the lining are formed into a three-dimensional structure by folding a flat cardboard; the paper box 10 and the lining each have a self-locking structure, and through the self-locking structure, the folding joints can be firmly buckled to achieve self-locking, so as to fix the formed paper box 10 and the lining. And, their respective self-locking structures are directly formed on the paper box 10 and the lining itself, and the paper box 10 and the lining and their respective self-locking structures are integrally formed. In this way, there is no need to use tapes, glues, etc. in the prior art for fixing, and the paper box 10 and the lining can be environmentally fixed and formed through their respective self-locking structures, realizing complete environmental protection in packaging. At the same time, through the optimization of the paper box 10 and the lining, the amount of packaging materials is reduced, and the packaging material cost is optimized.

[0038] Specifically, for the paper box 10, it has a receiving cavity 10A; in the embodiment of the present application, the receiving cavity 10A is a rectangular cavity, and the box cover 113, the first flap structure 110, the side pressing structure 112 and the second flap structure 111 of the paper box 10 are sequentially connected to the four surrounding side walls of the receiving cavity 10A. The side pressing structure 112 is used to be folded back into the receiving cavity 10A and is located on the first lining 20 and the second lining 30 in the receiving cavity 10A, and the first flap structure 110 and the second flap structure 111 are folded back on the side pressing structure 112 in the receiving cavity 10A.

[0039] The setting of the swing cover structure can limit the position of the product through the swing cover structure when the inner liner cannot fill the accommodation cavity 10A, so as to protect the product in the accommodation cavity 10A from displacement and shaking. In addition, the swing cover structure itself will form an accommodation space, which can be used to place products or product accessories additionally, so that more products and their accessories can be placed in the all-paper packaging box to meet the packaging requirements.

[0040] From Figure 2 It can be seen that the first swing cover structure 110 and the second swing cover structure 111 are oppositely arranged on the side wall of the accommodation cavity 10A, and the first swing cover structure 110 and the second swing cover structure 111 each form a bent shape with the opening facing inwards; on the other two opposite side walls of the accommodation cavity 10A, a box cover 113 and a side pressing structure 112 are respectively arranged.

[0041] During use, first put the first inner liner 20 and the second inner liner 30 into the accommodation cavity 10A, as Figure 3 then fold the side pressing structure 112 backwards and put it into the accommodation cavity 10A, and press it on the first inner liner 20 and the second inner liner 30, and use the first inner liner 20 and the second inner liner 30 to support the side pressing structure 112; as Figure 4 subsequently, fold the first swing cover structure 110 and the second swing cover structure 111 on both sides backwards into the accommodation cavity 10A and press them on the side pressing structure 112.

[0042] When the first swing cover structure 110 and the second swing cover structure 111 are folded backwards in the accommodation cavity 10A, a card slot area 19 is also formed between the first swing cover structure 110 and the second swing cover structure 111. The card slot area 19 is used to accommodate product accessories to form an overall classified packaging for the product.

[0043] The above outlines the structure of the carton 10, and the carton 10 is integrally formed, that is, formed by folding a whole piece of cardboard; for example, referring to Figure 5 , the carton 10 includes a side pressing cardboard 10a, a first swing cover cardboard 10b, a bottom cardboard 10c and a second swing cover cardboard 10d that are sequentially connected along the first direction F1. The side pressing cardboard 10a, the first swing cover cardboard 10b, the bottom cardboard 10c and the second swing cover cardboard 10d can be regarded as areas divided from a whole piece of cardboard.

[0044] Among them, the side pressing cardboard 10a, the first swing cover cardboard 10b, the bottom cardboard 10c and the second swing cover cardboard 10d are folded along the folding lines to enclose and form the accommodation cavity 10A;

[0045] A box cover area is also provided on the bottom cardboard 10c to form the box cover 113. The box cover 113 also forms a bent edge, and a second buckle 18 is arranged at the bent part to facilitate subsequent self-locking with the first tongue 11 of the side pressing cardboard 10a;

[0046] A side pressing cardboard 10a is also provided with a side pressing area to form a side pressing structure 112. Chamfers are formed at the four corners of the side pressing area. Through the chamfers along the tooth cutter line, three sides of the side pressing cardboard 10a are also bent to fully cover the accommodation cavity 10A and prevent the products in the accommodation cavity 10A from being exposed outside the package.

[0047] First flap cardboard 10b and second flap cardboard 10d are also respectively formed with a first flap area and a second flap area. The first flap area and the second flap area are located at the same end as the side pressing area in the second direction F2 perpendicular to the first direction F1. The first flap area is used to form a first flap structure 110, and the second flap area is used to form a second flap structure 111.

[0048] Taking the first flap cardboard 10b as an example, Figure 5 A first flap area is formed at the upper end of the first flap cardboard 10b. The first flap area can be folded along its folding line to form a first flap structure 110. A first dust-proof wing 14 is also formed at the lower end of the first flap cardboard 10b, and a second dust-proof wing 16 is also formed at the lower end of the second flap cardboard 10d. The cuts of the first dust-proof wing 14 and the second dust-proof wing 16 are arranged oppositely in the first direction F1.

[0049] Along the second direction F2, a tongue 13 is formed at the end of the side pressing cardboard 10a, and a concave opening 15 is formed at the end of the bottom cardboard 10c. The tongue 13 and the concave opening 15 are located at the same end in the second direction F2. After the bottom cardboard 10c with the self-locking concave opening 15 at the bottom of the carton 10 is bent 90 degrees, the first dust-proof wing 14 and the second dust-proof wing 16 press against the concave opening 15, and the tongue 13 is inserted into the concave opening 15 for matching to realize the bottom self-locking of the carton 10.

[0050] When the side of the carton 10 is self-locked, along the first direction F1, a first tongue 11 is formed at the end of the side pressing cardboard 10a, and a first buckle 12 is formed at the end of the second flap cardboard 10d. The first tongue 11 and the first buckle 12 are arranged opposite to each other and match for self-locking.

[0051] After the side pressing cardboard 10a, the first flap cardboard 10b, the bottom cardboard 10c, and the second flap cardboard 10d are respectively folded 90 degrees, the first tongue 11 and the first buckle 12 are self-locked to realize the side self-locking of the carton 10.

[0052] When the top of the carton 10 is self-locked, along the second direction F2, a second buckle 18 is formed at the end of the bottom cardboard 10c relative to the concave opening 15, and a second tongue 17 is formed in the middle of the side pressing cardboard 10a. When the lid 113 at the top of the carton 10 is inserted into the accommodation cavity 10A of the carton 10, the second buckle 18 of the lid 113 and the second tongue 17 form self-locking to complete the top self-locking of the carton 10.

[0053] Since then, after the carton 10 is folded and enclosed, the bottom, side, and top of the carton 10 are all self-locked, enabling the carton 10 to form self-locking through its own self-locking structure without external objects such as tape.

[0054] Further, for the first inner liner 20, it is formed by folding the first liner board Figure 7 and is integrally formed with a self-locking structure.

[0055] The first liner board is divided into a plurality of successively connected first folding areas 20a along the fold line in the second direction F2. After folding to form the first inner liner 20, the plurality of first folding areas 20a are successively vertically connected;

[0056] The self-locking structure includes a slot 22 and a bayonet 21 respectively provided on the outermost two first folding areas 20a. The slot 22 is provided along the first direction F1, and the bayonet 21 is provided along the second direction F2. The slot 22 and the bayonet 21 are matched for self-locking.

[0057] Exemplarily, as Figure 7 shown, the first liner board is divided into five first folding areas 20a along the second direction F2. After the five first folding areas 20a are folded 90 degrees along the fold line in the second direction F2, the slot 22 and the bayonet 21 on the outermost two first folding areas 20a coincide for self-locking. After the slot 22 and the bayonet 21 are self-locked, the toothed knife lines 23, 24, and 25 are pressed and formed to obtain Figure 6 the first inner liner 20 with the shape shown; the first inner liner 20 is placed in the accommodation cavity 10A of the carton 10 and can be used for product positioning.

[0058] The second inner liner 30 includes a second liner board. The second liner board is divided into a plurality of successively connected second folding areas 30a along the fold line in the second direction F2. In the formed second inner liner 30 structure after folding, the plurality of second folding areas 30a are successively vertically connected; the self-locking structure includes first slits respectively provided on the outermost two second folding areas 30a. The two first slits are provided along the second direction F2 and are matched for self-locking.

[0059] Exemplarily, as Figure 9 shown, the second liner board is divided into five second folding areas 30a along the second direction F2. After the five second folding areas 30a are folded 90 degrees along the fold line in the second direction F2, the first slit 31 and the first slit 32 on the outermost two second folding areas 30a coincide for self-locking.

[0060] After the first slot 31 and the first slot 32 are self-locked, two second folding areas 30a that are second outermost and connected to the two outermost second folding areas 30a are respectively provided with two clamping plates and two second slots. The clamping plates and the second slots are matched and self-locked. The second slots are arranged along the second direction F2, and the clamping plates are bent along the third direction F3. The third direction F3 is perpendicular to the first direction F1 and the second direction F2 in pairs.

[0061] Exemplarily, the clamping plate 35 and the clamping plate 36 are folded down (in the third direction F3) by 90 degrees and respectively clamped at the positions of the second slot 33 and the second slot 34, thereby forming a self-lock. The formed shape is like Figure 8 the second inner lining 30 shown. The second inner lining 30 is placed in the accommodation cavity 10A of the carton 10, and the middle part of the second inner lining 30 is vacant and can be used to hold the accessories of the product.

[0062] The above are only the embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application.
