[0056] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0057] Traditional carton packaging has handle holes on the side. When transporting, the cardboard where the handle holes are located only relies on the lifting force, which is very easy to be damaged. The handle holes have weak bearing strength and are easy to cut your hands. They are also easy to get dust in and contaminate the products inside the package.

[0058] Based on this, the following embodiments are proposed:

[0059] Example 1

[0060] like Figure 1 、 Figures 3 to 7 As shown, this embodiment provides a packaging box, including:

[0061] A first box side wall 1, wherein a through hole 101 is formed on the first box side wall 1, and a cutout group is provided on the first box side wall 1 and located around the through hole 101;

[0062] The second box side wall 4, one side of the second box side wall 4 extends to form a first folding plate 2, the outer periphery of the first folding plate 2 extends to form an inserting tongue group, the first folding plate 2 is extended into the inner side of the first box side wall 1, the first folding plate 2 correspondingly covers the perforation 101, and the inserting tongue group is correspondingly inserted into the incision group to realize the connection between the second box side wall 4 and the first box side wall 1, and by folding the inserting tongue group relative to the first folding plate 2, the inserting tongue group and the first folding plate 2 together enclose a handle groove.

[0063] In this embodiment, the handle groove structure of the packaging box is designed as a sealed embedded handle groove, by providing a perforation 101 on the first box side wall 1, and providing a cutout group on the outer peripheral side of the perforation 101, a first folding plate 2 is provided on the second box side wall 4 of the packaging box, that is, the cardboard rocker cover, and a tongue group corresponding to the cutout group is provided on the first folding plate 2. The tongue group can be an arrow-shaped loose-leaf, and the multiple tongues in the tongue group are respectively embedded in the multiple cutouts in the cutout group to form a matching connection with the multiple cutouts to achieve the connection between the second box side wall 4 and the first box side wall 1. After the multiple tongues are respectively embedded in the multiple cutouts, the first box side wall 4 is pressed toward the inside of the packaging box along the perforation 101. The folding plate 2 and the tongue portion are bent along multiple folds to form multiple side walls of the handle groove, and the first folding plate 2 itself forms the bottom wall 209 of the handle groove, so that the handle groove structure forms a force-bearing groove body. Since the first folding plate 2 blocks the perforation 101, the handle groove structure forms a seal for the perforation 101 on the packaging box. By folding the tongue group relative to the first folding plate 2, the tongue group and the first folding plate 2 are jointly enclosed to form the handle groove. While ensuring the sealing of the packaging box, it is more convenient for the carrier to directly put his fingers into the groove body, and the side walls of the groove body are in a distributed force-bearing manner, which also largely avoids damaging the lifting position of the packaging box.

[0064] When the porter needs a handle groove, he can press the first folding plate 2 and apply force to the inside of the packaging box along the position of the perforation 101, so that the indentation line on the tongue of the tongue group is concave inward to form an embedded handle groove, such as Figure 4 As shown, the outermost indentations on the multiple tongues are aligned with the multiple cutouts. The embedded handle slots ensure the box's tightness, distributing the force when handling the carton, and preventing damage to the lifting position, ensuring the box's tightness and anti-theft properties.

[0065] The handle grooves designed on the packaging box can increase the force-bearing area between the hands and the carton during transportation, making it easier to carry. The handle grooves are designed as embedded structures by the front or rear cardboard swing cover, that is, the handle grooves are formed on the front and rear walls of the packaging box to avoid exposing the through holes, ensuring the sealing of the carton and preventing dust and other external debris from entering the interior and contaminating the products.

[0066] Optionally, in an implementation of this embodiment, as Figure 7 As shown,

[0067] A first box side wall 1 and a second box side wall 4 are integrally connected to form a box side wall assembly, and the first folding plate 2 is arranged on the second box side wall 4 at a side away from the first box side wall 1;

[0068] The tongue groups and the notch groups of the two box side wall components are respectively plugged in to enclose and form the peripheral side wall of the packaging box.

[0069] In this embodiment, the tongue assemblies and notch assemblies of the two side wall assemblies are respectively plugged into each other to enclose and form the peripheral side walls of the packaging box. Specifically, the handle slots are formed on the front and rear side walls of the packaging box, or the handle slots can also be formed on the left and right side walls of the packaging box, so that the transporter can carry the packaging box using the handle slots with both hands. It is understood that not only two handle slots can be provided, but also four handle slots can be provided as needed, located on the four side walls of the packaging box. The specific number of handle slots is based on actual needs and is not limited.

[0070] Optionally, in an implementation of this embodiment, as Figure 1 、 3 -7,

[0071] The tongue assembly includes a first tongue 201 extending along a first direction of the first folding plate 2, a second tongue 202 extending along a second direction of the first folding plate 2, and a third tongue 203 extending along a third direction of the first folding plate 2. The first folding plate 2 extends along a fourth direction to form a connecting plate 204, and the first folding plate 2 is integrally connected to the second box side wall 4 via the connecting plate 204.

[0072] The incision group includes a first incision 102 located in a first direction of the periphery of the through hole 101, a second incision 103 located in a second direction of the periphery of the through hole 101, and a third incision 104 located in a third direction of the periphery of the through hole 101.

[0073] The first inserting tongue 201 is inserted into and snapped into the first notch 102 , the second inserting tongue 202 is inserted into and snapped into the second notch 103 , and the third inserting tongue 203 is inserted into and snapped into the third notch 104 , thereby achieving connection between the second box side wall 4 and the first box side wall 1 .

[0074] Furthermore, the first inserting tongue 201 has a first fold group arranged along the first direction, the second inserting tongue 202 has a second fold group arranged along the second direction, the third inserting tongue 203 has a third fold group arranged along the third direction, and the connecting plate 204 has a fourth fold group arranged along the fourth direction.

[0075] The first folding plate 2 is pressed toward the inner side of the packaging box along the perforation 101, and a portion of the first inserting tongue 201 is bent along the first fold group to form the first side wall 205 of the handle groove, a portion of the second inserting tongue 202 is bent along the second fold group to form the second side wall 206 of the handle groove, a portion of the third inserting tongue 203 is bent along the third fold group to form the third side wall 207 of the handle groove, a portion of the connecting plate 204 is bent along the fourth fold group to form the fourth side wall 208 of the handle groove, and the first folding plate 2 forms the bottom wall 209 of the handle groove.

[0076] In this embodiment, the first folding plate 2 has a first inserting tongue 201 extending along the first direction, a second inserting tongue 202 extending along the second direction, a third inserting tongue 203 extending along the third direction, and a connecting plate 204 extending along the fourth direction;

[0077] The first tongue 201 has a first fold group arranged along a first direction, the second tongue 202 has a second fold group arranged along a second direction, the third tongue 203 has a third fold group arranged along a third direction, and the connecting plate 204 has a fourth fold group arranged along a fourth direction.

[0078] The first direction, the second direction, the third direction, and the fourth direction are all different;

[0079] The first folding plate 2 is designed as follows: the first inserting tongue 201 is inserted into and snapped into the first notch 102 , the second inserting tongue 202 is inserted into and snapped into the second notch 103 , and the third inserting tongue 203 is inserted into and snapped into the third notch 104 , so that the first folding plate 2 is shielded from the through hole 101 ;

[0080] The first folding plate 2 is pressed toward the inside of the packaging box along the perforation 101. Part of the first inserting tongue 201 is bent along the first fold group to form a first side wall 205 of the handle groove. Part of the second inserting tongue 202 is bent along the second fold group to form a second side wall 206 of the handle groove. Part of the third inserting tongue 203 is bent along the third fold group to form a third side wall 207 of the handle groove. Part of the connecting plate 204 is bent along the fourth fold group to form a fourth side wall 208 of the handle groove. The first folding plate 2 forms a bottom wall 209 of the handle groove.

[0081] In this embodiment, the handle groove structure of the packaging box is designed as a sealed embedded handle groove, by providing a perforation 101 on the first box side wall 1, and providing a cutout group around the perforation 101, namely a first cutout 102, a second cutout 103 and a third cutout 104, a first folding plate 2 is provided on the side wall of the packaging box, that is, on the cardboard swing cover, and three arrow-shaped loose-leafs in three directions, namely a first plug-in tongue 201, a second plug-in tongue 202 and a third plug-in tongue 203, are provided on the first folding plate 2. The three plug-in tongues are respectively embedded in the three cutouts to form a mating connection with the three cutouts. The connecting plate 204 is used to form an integral connection between the first folding plate 2 and the side wall of the packaging box. After the three plug-in tongues are respectively embedded in the three cutouts, the first folding plate 2 is pressed toward the inside of the packaging box along the perforation 101, and the first plug-in tongue 201 is pressed against the inside of the packaging box. The portion of the second tongue 202 is bent along the first fold group to form the first side wall 205 of the handle groove, the portion of the second tongue 202 is bent along the second fold group to form the second side wall 206 of the handle groove, the portion of the third tongue 203 is bent along the third fold group to form the third side wall 207 of the handle groove, the portion of the connecting plate 204 is bent along the fourth fold group to form the fourth side wall 208 of the handle groove, and the first folding plate 2 forms the bottom wall 209 of the handle groove. Thus, the handle groove structure forms a force-bearing groove body. Since the first folding plate 2 blocks the perforation 101, the handle groove structure forms a seal with the perforation 101 on the packaging box. While ensuring the sealing of the packaging box, it is more convenient for the carrier to directly put his fingers into the groove body. Moreover, the side walls of the groove body are in a distributed force-bearing manner, which also largely avoids damaging the lifting position of the packaging box.

[0082] More specifically, Figure 6 、 7 As shown, the first tongue 201 has a first fold group of three indentations arranged along a first direction, the second tongue 202 has a second fold group of three indentations arranged along a second direction, the third tongue 203 has a third fold group of three indentations arranged along a third direction, and the connecting plate 204 has a fourth fold group of two indentations arranged along a fourth direction. When assembling the handle slot structure on the packaging box, each tongue is inserted into the corresponding incision so that the middle indentations on the three tongues are aligned with the three incisions respectively, as shown in FIG. Figure 3 As shown, the handle structure is now flush with the side wall of the packaging box.

[0083] When the porter needs a handle slot, he can press the first folding plate 2 and apply force to the inside of the packaging box along the position of the perforation 101, so that the indentation lines on the three tongues and the indentation lines on the connecting plate 204 are concave inward to form an embedded handle slot, such as Figure 4As shown, the outermost indentations on the three tongues now align with the three notches. The width of the first notch 102 is greater than that of the first tongue 201, and the width of the third notch 104 is greater than that of the third tongue 203. This facilitates insertion of the tongues and allows for movement during the shaping of the handle slot. The recessed handle slot ensures the box's tightness, distributes the force during manual handling, and avoids damage to the lifting position, ensuring a tight and theft-proof package.

[0084] The handle grooves designed on the packaging box can increase the force-bearing area between the hands and the carton during transportation, making it easier to carry. The handle grooves are designed as embedded structures by the front or rear cardboard swing cover, that is, the handle grooves are formed on the front and rear walls of the packaging box to avoid exposing the through holes, ensuring the sealing of the carton and preventing dust and other external debris from entering the interior and contaminating the products.

[0085] Optionally, in an implementation of this embodiment, as Figure 7 As shown,

[0086] The first folding plate 2 is constructed as a square plate, and the first inserting tongue 201 , the second inserting tongue 202 , the third inserting tongue 203 and the connecting plate 204 are respectively located at the four edges of the first folding plate 2 .

[0087] In this embodiment, the first inserting tongue 201 and the third inserting tongue 203 are respectively arranged at the upper edge and the lower edge of the first folding plate 2, and the first inserting tongue 201 and the third inserting tongue 203 are symmetrical, the second inserting tongue 202 and the connecting plate 204 are respectively arranged at the left edge and the right edge of the first folding plate 2, and the second inserting tongue 202 is symmetrical to the connecting plate 204, thereby forming a square groove body that can bear force. Since the first folding plate 2 blocks the through-hole 101, the handle groove structure forms a seal with the through-hole 101 on the packaging box. While ensuring the sealing of the packaging box, it is more convenient for the carrier to directly put his fingers into the groove body, and the side walls of the groove body adopt a distributed force-bearing method, that is, the first side wall 205, the second side wall 206, the third side wall 207 and the fourth side wall 208 will respectively bear part of the gravity of the packaging box, thereby largely avoiding damage to the lifting position of the packaging box.

[0088] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0089] The first inserting tongue 201, the second inserting tongue 202, and the third inserting tongue 203 each have a first clamping portion 210 at one end away from the first folding plate 2, and the first clamping portion 210 is used to clamp with the corresponding notch in the notch group;

[0090] The width of at least one first engaging portion 210 of the first inserting tongue 201 , the second inserting tongue 202 , and the third inserting tongue 203 is greater than the width of the corresponding cutout in the cutout group.

[0091] Furthermore, the first engaging portion 210 of the second inserting tongue 202 is inserted into the second notch 103, and both ends of the first engaging portion 210 protrude from the two side edges of the second notch 103, thereby achieving an engaging state between the second inserting tongue 202 and the second notch 103;

[0092] The first engaging portion 210 of the first inserting tongue 201 is inserted into the first notch 102 , and at least one end of the first engaging portion 210 protrudes from a side edge of the first notch 102 , thereby achieving an engaging state between the first inserting tongue 201 and the first notch 102 ;

[0093] The first engaging portion 210 of the third inserting tongue 203 is inserted into the third notch 104 , and at least one end of the first engaging portion 210 protrudes from a side edge of the third notch 104 , thereby achieving an engaging state between the third inserting tongue 203 and the third notch 104 .

[0094] Preferably, one end of the first clamping portion 210 away from the first protruding portion is configured as a first tip 211 .

[0095] In this embodiment, the side of the first inserting tongue 201, the second inserting tongue 202 and the third inserting tongue 203 away from the first folding plate 2 is designed to be arrow-shaped, that is, the first tip 211 of the first clamping portion 210 away from the first protruding portion is the tip of the arrow shape, and the end of the first clamping portion 210 close to the first folding plate 2 is the first protruding portion, that is, the first protruding portion is the root of the arrow shape. The first protruding portion is designed to be protruding at both ends. The above design facilitates the first inserting tongue 201, the second inserting tongue 202 and the third inserting tongue 203 to be inserted into the first incision 102, the second incision 103 and the third incision 104, respectively. Regarding the third incision 104, it is understandable that although the first engaging portion 210 is wider than the corresponding incision, it can be inserted into the corresponding incision by slightly bending and deforming. After insertion into the incision, the first engaging portion 210 recovers its deformation, thereby forming a locking engagement with the edge of the corresponding incision. When the inserting tongue is inserted into the corresponding incision, the two ends of the first engaging portion are locked at the two ends of the corresponding incision, or one end of the first engaging portion is locked at the corresponding incision, so that the arrow-shaped inserting tongue can be inserted into the corresponding incision. The locking point between the first engaging portion and the corresponding incision only needs to be sufficient to prevent the inserting tongue from falling out of the corresponding incision.

[0096] Optionally, in an implementation of this embodiment, as Figure 1 、 Figure 3-8 As shown, the packaging box also includes:

[0097] A top cover 3, wherein a fourth notch 303 is provided on the top cover 3;

[0098] A fourth inserting tongue 105 is formed on the first box side wall 1 or the second box side wall 4 , and the fourth inserting tongue 105 is inserted into and engaged with the fourth notch 303 to achieve the connection between the first box side wall 1 and the top cover 3 , or the connection between the second box side wall 4 and the top cover 3 .

[0099] Furthermore, the top cover 3 includes a first top cover 301 and a second top cover 302 , the first top cover 301 is provided with a fourth incision A3031 , and the second top cover 302 is provided with a fourth incision B3032 ;

[0100] The fourth inserting tongue 105 is formed by extending from the upper side of the first box side wall 1;

[0101] The first top cover 301 is formed by extending from the upper side of one of the second box side walls 4 , and the second top cover 302 is formed by extending from the upper side of the other second box side wall 4 ;

[0102] The first top cover 301 and the second top cover 302 are spliced to form the top wall of the packaging box. The fourth incision A 3031 and the fourth incision B 3032 together form the fourth incision 303 . The fourth inserting tongue 105 is inserted into and engaged with the fourth incision 303 .

[0103] In this embodiment, the side walls of the packaging box include first box side walls 1 opposite to each other along the width direction of the packaging box and second box side walls 4 opposite to each other along the length direction of the packaging box.

[0104] A fourth inserting tongue 105 is formed on each of the two first box side walls 1;

[0105] The first top cover 301 is formed on one second box side wall 4, and the second top cover 302 is formed on the other second box side wall 4;

[0106] The fourth cutout A3031, the fourth cutout B3032 and the fourth inserting tongue 105 are designed such that when the first top cover 301 and the second top cover 302 are in the closed state at the top of the packaging box, the fourth cutout A3031 and the fourth cutout B3032 together form the fourth cutout 303, and the fourth inserting tongue 105 is inserted into and snapped into the fourth cutout 303.

[0107] With the continuous rise of global environmental awareness and the advancement of sustainable development strategies, green development has become a key trend in global economic development. Domestically and internationally, various industries are being urged to accelerate green transformation and have issued relevant plastic bans. Against this backdrop of green development, traditional cardboard packaging utilizes extensive amounts of non-degradable plastic products, such as adhesive tape and adhesive paper, which can easily cause environmental pollution and require manual operation, resulting in low efficiency. In this embodiment, the packaging box proposed utilizes the fourth tongue 105 in conjunction with the fourth notch 303 to achieve sealing, eliminating the need for any sealing tape. This eliminates plastic pollution, saves costs, improves packaging efficiency, and achieves full recyclability of the packaging materials.

[0108] In this embodiment, if the side wall of the packaging box is formed by the first box side wall 1 and the second box side wall 4, as shown in FIG. Figure 3 As shown, the number of first box side walls 1 is two, and the two first box side walls 1 serve as the left and right side walls of the packaging box. The number of second box side walls 4 is two, and the two second box side walls 4 serve as the front and rear side walls of the packaging box. A handle groove structure is formed on each of the left and right side walls, and a fourth inserting tongue 105 is formed on each of the two first box side walls 1; a first top cover 301 is integrally connected to one second box side wall 4, and a second top cover 302 is integrally connected to the other second box side wall 4; when the first top cover 301 and the second top cover 302 are in the closed state at the top of the packaging box, the fourth sub-cut A 3031 and the fourth sub-cut B 3032 jointly form a fourth cut 303, and the fourth inserting tongue 105 is inserted into and snapped into the fourth cut 303. If the side walls of the packaging box are completely enclosed by the first box side walls 1, the number of the first box side walls 1 is 4. The four first box side walls 1 serve as the front and rear, left and right side walls of the packaging box. The front and rear, left and right side walls each have a handle groove structure, two symmetrical first side walls 1 are respectively integrally connected to the first top cover 301 and the second top cover 302, and the other two symmetrical first side walls 1 are respectively integrally connected to a fourth tongue 105.

[0109] The aforementioned top-of-box locking structure features inner flap fixing tongues on both sides, namely, fourth tongues 105 formed on both first sidewalls 1. The outer flap is designed with fixed tongue slots, namely, a first top cover 301 integrally connected to one second sidewall 4, and a second top cover 302 integrally connected to the other second sidewall 4. When the first and second top covers 301 and 302 are closed, fourth incisions A 3031 and B 3032 together form a fourth notch 303. The inner flap fixing tongues insert from the outside inward into the flap fixing tongue slots, namely, the fourth tongues 105 insert and engage with the fourth notch 303, achieving a self-locking effect. The flap fixing tongues on the left and right sides of the top insert into the limit cuts of the front and rear flaps to seal the box, thus providing the box with self-locking and anti-theft functions and suitable for packaging products requiring both anti-theft and sealing. The packaging box proposed in this embodiment is formed from folded cardboard and achieves self-locking through a nested design.

[0110] Optionally, in an implementation of this embodiment, as Figures 6 to 8 As shown,

[0111] The end of the fourth inserting tongue 105 inserted into the fourth notch 303 has a second clamping portion 3034, and the second clamping portion 3034 is used to clamp with the fourth notch 303;

[0112] The width of the second clamping portion 3034 is greater than the width of the fourth notch 303 .

[0113] Furthermore, when the second clamping portion 3034 is clamped with the fourth cutout 303 , both ends of the second clamping portion 3034 protrude from both side edges of the fourth cutout 303 .

[0114] Preferably, one end of the second clamping portion 3034 away from the second protruding portion is configured as a second tip 3033 .

[0115] In this embodiment, the fourth inserting tongue 105 is designed in an arrowhead shape. Specifically, the second tip 3033 of the second engaging portion 3034, which is distal to the second protruding portion, is the tip of the arrowhead shape. The end of the second engaging portion 3034, which is closer to the fourth inserting tongue 105, is the second protruding portion, i.e., the second protruding portion is the root of the arrowhead shape. This second protruding portion is designed to protrude at both ends. This design facilitates insertion of the fourth inserting tongue 105 into the fourth notch 303. The two ends of the second engaging portion 3034 engage with the ends of the fourth notch 303, making it easier for the fourth inserting tongue 105 to be inserted into the fourth notch 303 while preventing it from slipping out, thereby achieving an effective self-locking function. It is understood that although the second engaging portion 3034 is wider than the fourth notch 303, it can be inserted into the fourth notch 303 by slightly bending and deforming. After insertion, the second engaging portion 3034 returns to its original shape, locking with the corresponding edge of the fourth notch 303.

[0116] Optionally, in an implementation of this embodiment, as Figures 6 to 8 As shown,

[0117] A locking groove 3011 is formed on the first top cover 301, and a locking hook 3021 is formed on the second top cover 302;

[0118] When the first top cover 301 and the second top cover 302 are in a state of closing the top of the packaging box, the locking groove 3011 and the locking hook 3021 are engaged with each other.

[0119] In this embodiment, a hidden lock structure is designed on the top cover 3 of the packaging box. The lock structure consists of a lock groove 3011 and a lock hook 3021. On the basis of having an anti-theft function, the packaging box further ensures that the surface of the packaging box is smooth when locked. The lock structure is completely hidden inside the packaging box, making it difficult to be noticed and difficult for people to crack it.

[0120] The packaging box provided in this embodiment has the functions of dustproof and anti-theft by improving the cardboard forming structure, and is easy to carry, thereby ensuring its safety and stability during storage and transportation.

[0121] Optionally, in an implementation of this embodiment, as Figure 1 、 2 , 6,

[0122] The locking groove 3011 is constructed as a locking groove plate protruding from the first top cover 301, and the locking groove plate is provided with a first fold 3012, a second fold 3013 and a third fold 3014;

[0123] The lock hook 3021 is constructed as a lock hook sheet protruding from the second top cover 302, and a fourth fold 3022 and a fifth fold 3023 are provided on the lock hook sheet;

[0124] A locking groove 3011 with an insertion opening is formed by bending along the first fold 3012, the second fold 3013 and the third fold 3014;

[0125] Bending along the fourth fold 3022 and the fifth fold 3023 to form a lock hook 3021;

[0126] When the first top cover 301 and the second top cover 302 are in a state of closing the top of the packaging box, the locking hook 3021 enters the locking slot 3011 through the insertion port and is locked in the locking slot 3011 .

[0127] Furthermore, the first fold 3012 and the second fold 3013 are bent to form a first groove wall 3015 of the locking groove 3011, the second fold 3013 and the third fold 3014 are bent to form a second groove wall 3016 of the locking groove 3011, and the third fold 3014 is bent to form a third groove wall 3017 of the locking groove 3011;

[0128] There is a distance between the first slot wall 3015 and the third slot wall 3017 to form the insertion port;

[0129] The fourth fold 3022 and the fifth fold 3023 are bent to form a first hook wall 3024 of the lock hook 3021, and the fifth fold 3023 is bent to form a second hook wall 3025 of the lock hook 3021;

[0130] When the locking hook 3021 is located in the locking groove 3011 , the second hook wall 3025 abuts against the first groove wall 3015 , and the third groove wall 3017 abuts against the second top cover 302 .

[0131] In this embodiment, Figure 2 As shown, the locking groove 3011 is bent along the first fold 3012, the second fold 3013 and the third fold 3014 to form a groove structure with an insertion opening. The groove structure includes a first groove wall 3015, a second groove wall 3016 and a third groove wall 3017. The first groove wall 3015 and the third groove wall 3017 are spaced apart to form the insertion opening. The first groove wall 3015, the second groove wall 3016 and the third groove wall 3017 form a V-shaped groove structure.

[0132] The lock hook 3021 is bent along the fourth fold 3022 and the fifth fold 3023 to form a hook structure, which includes a first hook wall 3024 and a second hook wall 3025. The first hook wall 3024 and the second hook wall 3025 form a V-shaped hook structure.

[0133] The locking slot 3011 and the locking hook 3021 are designed so that when the first top cover 301 and the second top cover 302 are in a closed state, the hook structure enters the slot structure through the insertion port and is engaged with the slot structure.

[0134] The V-shaped hook structure utilizes the resilience of the cardboard at the indentation to be inserted into the V-shaped groove structure, so that the two outer flaps, namely the first top cover 301 and the second top cover 302, are locked to each other. The locking groove 3011 and the locking hook 3021 are hidden inside the packaging box and are not easy to be discovered. The packaging box can only be opened by violent means to obtain the products inside, thereby achieving anti-theft requirements.

[0135] When sealing the box, first, the locking hook 3021 on the second top cover 302 is inserted into the locking groove 3011 through the insertion port and locked in the locking groove 3011, thereby locking the outer flap formed by the first top cover 301 and the second top cover 302. Then, the fixed tongue plate on the inner flap, that is, the fourth tongue 105 on the inner flap, is inserted along the fourth notch 303 of the outer flap to complete the box sealing operation.

[0136] In summary, the ingenious design of the packaging box is:

[0137] First, the handle slot structure of the packaging box is designed as a sealed embedded handle slot. A perforation is set on the side wall of the first box, and a cut group is set around the perforation. A first folding plate is set on the side wall of the packaging box, and arrow-shaped hinges in three directions are set on the first folding plate. Three tongues are respectively embedded in the three cuts to form a matching connection with the three cuts. After the three tongues are respectively embedded in the three cuts, the first folding plate is pressed toward the inner side of the packaging box along the perforation, so that the handle slot structure forms a force-bearing slot body. Since the first folding plate blocks the perforation, the handle slot structure forms a seal on the perforation on the packaging box, preventing dust and other external debris from entering the interior and contaminating the product. While ensuring the sealing of the packaging box, it is more convenient for the carrier to directly buckle his fingers into the slot body, and the side walls of the slot body are in a distributed force-bearing manner, which also largely avoids damaging the lifting position of the packaging box.

[0138] Second, the box's top flap lock mechanism allows the left and right flap tabs to be inserted into the limited notches on the front and rear flaps to seal the box, providing a self-locking and anti-theft feature. Suitable for packaging products requiring both theft protection and sealing. The box is folded from cardboard and features a nested design that achieves self-locking. The left and right flaps are secured with internal flap tabs, while the outer flap has fixed tab slots. The internal flap tabs slot inwards, inserting from the outside inwards, achieve self-locking.

[0139] Third, a hidden latch mechanism is designed into the top cover of the packaging box. This not only provides anti-theft functionality but also ensures a smooth surface when locked. The latch mechanism is completely concealed within the box, making it difficult to detect and, therefore, difficult to crack. By improving the cardboard molding structure, the packaging box is both dust-proof and anti-theft, while also being easy to carry, ensuring safety and stability during storage and transportation.

[0140] Fourth, the V-shaped hook structure uses the resilience of the cardboard at the indentation to be inserted into the V-shaped groove structure, so that the outer flaps are locked with each other, and the locking groove and locking hook are hidden inside the packaging box, not easy to be found. The packaging box can only be opened by violent means to obtain the products inside, thus achieving better anti-theft requirements.
