[0028] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is merely intended to explain the present application, and is not intended to limit the present application. The present application can be implemented without some of the specific details, which are well known to those skilled in the art. The following description of the embodiments is merely intended to provide a better understanding of the present application through showing examples of the present application.

[0029] As Figures 1 to 4As shown, the hidden lock buckle type packaging box of the embodiment of the application comprises a first box body 10, which comprises a plurality of first side walls 11, a first containing cavity 12 formed by the plurality of first side walls 11, and a first opening 13 communicating with the first containing cavity 12. The two first side walls 11 located on opposite sides of the first opening 13 each have a first clamping structure 15 bent towards the inside of the first containing cavity 12. Each first clamping structure 15 is arranged at the end of the corresponding first side wall 11 located at the first opening 13. A second box body 20 is connected to the first box body 10 in a pullable manner and is arranged to enter and exit the first containing cavity 12 through the first opening 13. The second box body 20 comprises a box body 21 and a cover 23 connected by a tear line 22. The box body 21 comprises a plurality of second side walls 211 and a second containing cavity 212 formed by the plurality of second side walls 211. The cover 23 is tearably connected to at least two of the plurality of second side walls 211 by the tear line 22. Among the plurality of second side walls 211, two second side walls 211 arranged on opposite sides each have a second clamping structure 25 bent outward. The two second clamping structures 25 are respectively arranged in a coupled manner with the two first clamping structures 15 and can be clamped and matched, and the second clamping structure 25 avoids the cover 23.

[0030] It should be noted that the bending connection or the bending connection in the embodiment of the application has a crease between two adjacent structures. The two structures can be bent at any angle through the crease to meet the shape requirements of the final packaging box.

[0031] In specific implementation, the hidden lock buckle type packaging box of the embodiment of the application comprises a first box body 10 and a second box body 20. The second box body 20 is pullably connected to the first opening 13 of the first box body 10. The first clamping structure 15 of the first side wall 11 located on opposite sides of the first opening 13 of the first box body 10 can be clamped and matched with the corresponding second clamping structure 25 of the second side wall 211 of the second box body 20. After the second box body 20 is pulled out a certain distance from the first opening 13, the clamping and matching between the first clamping structure 15 and the second clamping structure 25 is completed, thereby avoiding the second box body 20 from being completely pulled out of the first containing cavity 12.

[0032] Among them, the two first clamping structures 15 are arranged at the ends of the two first side walls 11 close to the first opening 13, and the two second clamping structures 25 are also arranged at the ends of the two second side walls 211. Such arrangement can maximize the pulling distance between the second box body 20 and the first box body 10, facilitate the arrangement of a larger object taking opening on the second side wall 211 of the second box body 20, and facilitate the taking out of the objects contained in the second box body 20.

[0033] The first clamping structure 15 of the first box body 10 is bent inwardly in the first accommodating cavity 12, and the second clamping structure 25 of the second box body 20 is bent outwardly. When the first side wall 11 and the second side wall 211 are in contact, the first clamping structure 15 and the second clamping structure 25 can be clamped and matched with a small bending angle, so as to ensure that the first box body 10 has sufficient installation space. In addition, the cover 23 of the second box body 20 is connected to the second side wall 211 through the tearing line 22. After the second box body 20 is pulled out for a certain distance, the cover 23 can be torn to form an opening structure. Since the cover 23 is arranged away from the second clamping structure 25, when the internal containing articles of the second box body 20 are taken out through the opening structure, the second clamping structure 25 will not affect the taking out, so as to ensure the convenience of the packaging box.

[0034] In addition, the cover 23 is connected to the second side wall 211 through the tearing line 22. Before the second box body 20 is pulled out from the first accommodating cavity 12, the tearing line 22 of the cover 23 is not torn, and the cover 23 is fixedly connected to the second side wall 211, so as to protect the internal containing articles of the second box body 20 and prevent the containing articles from spilling. After the second box body 20 is pulled out from the first accommodating cavity 12 for a certain distance, the tearing line 22 can be torn to form an opening structure, so as to facilitate the taking out of the internal containing articles. Therefore, the setting of the tearing line 22 improves the use flexibility of the packaging box.

[0035] Specifically, the two first clamping structures 15 are respectively connected to the two first side walls 11 of the first box body 10 which are perpendicular to the first direction X. The two first side walls 11 which are perpendicular to the first direction X have a small overall area and a small extension length in the second direction Y. The two second clamping structures 25 are respectively connected to the two second side walls 211 of the second box body 20 which are perpendicular to the first direction X. The two second side walls 211 which are perpendicular to the first direction X also have a small area and a small extension length. The setting positions of the first clamping structure 15 and the second clamping structure 25 make the extension lengths of the first clamping structure 15 and the second clamping structure 25 in the second direction Y small. The two first side walls 11 and the two second side walls 211 which are perpendicular to the second direction Y can support the first clamping structure 15 and the second clamping structure 25 when the first clamping structure 15 and the second clamping structure 25 are clamped and matched, so as to limit the deformation of the first clamping structure 15 and the second clamping structure 25 and ensure the clamping stability of the first clamping structure 15 and the second clamping structure 25.

[0036] As shown in Figure 4 The hidden lock buckle type packaging box of the embodiment of the application, wherein the cover 23 comprises a first cover part 231 and a second cover part 232 which are bendably connected. The first cover part 231 is tearably connected with the second side wall 211 to which the second clamping structure 25 is connected. The second cover part 232 is tearably connected with another second side wall 211.

[0037] In practice, the first cover portion 231 and the second cover portion 232, which are bent and connected, are respectively connected to two adjacent second side walls 211. After the cover 23 is torn open as a whole, the user can take out the contents of the second box 20 from two different directions, which makes it more convenient for the user to take out the contents and improves the ease of use of the packaging box.

[0038] In the hidden latch type packaging box of this application embodiment, the first cover portion 231 has a rectangular structure and the second cover portion 232 has a trapezoidal structure. Along the direction away from the first cover portion 231, the width of the trapezoidal second cover portion 232 decreases. The end of the second cover portion 232 away from the first cover portion 231 is provided with a tear-out opening 233 at a distance from the second side wall 211.

[0039] In practice, the tear opening 233 between the end of the second cover portion 232 away from the first cover portion 231 and the second side wall 211 makes it easy for the user to put their hand in and tear the cover portion 23, reducing the difficulty of tearing and improving the ease of use of the packaging box.

[0040] Along the direction away from the first cover portion 231, the width of the trapezoidal second cover portion 232 decreases. When tearing by the tear opening 233, the second cover portion 232 can be torn from the side with the smallest width, which makes it easier for the user to tear. The first cover portion 231 has a rectangular structure and is connected to the wider side of the trapezoidal second cover portion 232, and has the same width as this side, thereby ensuring the continuity of the tear line 22. This allows the first cover portion 231 to continue along the tear line 22 after the second cover portion 232 is torn. Furthermore, after tearing, the rectangular first cover portion 231 can form a larger opening for easy retrieval.

[0041] like Figures 1 to 3 As shown in the embodiment of this application, the hidden lock packaging box has a first box body 10 with a third opening 16. The third opening 16 is opened on a first side wall 11 opposite to the first opening 13, and the opening area of ​​the third opening 16 is smaller than the area of ​​the first side wall 11 on which it is located.

[0042] In practice, the third opening 16 is opened on the first side wall 11 opposite to the first opening 13. When the second box 20 is pulled out, the user can push it outward from the third opening 16 toward the first opening 13 to facilitate the sliding of the second box 20 outward, thereby improving the ease of use of the packaging box.

[0043] The opening area of ​​the third opening 16 is smaller than the area of ​​the first side wall 11 on which it is located. This prevents the second box 20 from sliding out of the third opening 16 and ensures the installation stability of the second box 20 in the first receiving cavity 12.

[0044] As shown in Figure 3 and Figure 4 , the hidden lock type packaging box of the embodiment of the present application, wherein the connecting length of the first clamping structure 15 on the corresponding first side wall 11 is equal to the extension length of the first side wall 11; the connecting length of the second clamping structure 25 on the corresponding second side wall 211 is equal to the extension length of the second side wall 211.

[0045] In particular implementation, the two first side walls 11 and the two second side walls 211 perpendicular to the second direction Y can be completely arranged at both ends when the first clamping structure 15 and the second clamping structure 25 are clamped and matched, so as to completely limit the deformation of the first clamping structure 15 and the second clamping structure 25 in the second direction Y, avoid the first clamping structure 15 and the second clamping structure 25 from falling off, and ensure the clamping stability, so as to ensure the installation stability of the second box body 20 in the first containing cavity 12.

[0046] As shown in Figure 5 and Figure 6 , the embodiment of the present application further provides a plate blank for forming a hidden lock type packaging box, wherein it comprises a first folding structure 14 for folding to form a first box body 10 and a second folding structure 24 for folding to form a second box body 20, the first folding structure 14 comprises a first main body area 141, two groups of first packaging areas 142 connected to the first main body area 141 on both sides in the first direction X, and two first clamping structures 15 connected to the two groups of first packaging areas 142, and the second folding structure 24 comprises a second main body area 241, a second packaging area 242 arranged around the circumferential side of the second main body area 241, and two second clamping structures 25 connected to the second packaging area 242.

[0047] It should be noted that in the development diagram of Figure 5 and Figure 6 , the red line segment is the cutting line of the first folding structure 14 and the second folding structure 24, that is, the red cutting line is formed by cutting, and the two parts on both sides of the cutting line are independently arranged structures, which are separated by the cutting line; the blue line segment is the folding line of the first folding structure 14 and the second folding structure 24, and any two parts of the first folding structure 14 and the second folding structure 24 connected by the blue folding line can be bent along the folding line, so that the first folding structure 14 and the second folding structure 24 can be folded to form the first box body 10 and the second box body 20.

[0048] After the first folding structure 14 is folded to form the first box body 10, the first main body area 141 of the first folding structure 14 forms the first side wall 11 parallel to the first direction X, and the two groups of first packaging areas 142 form two first side walls 11 perpendicular to the first direction X; after the second folding structure 24 is folded to form the second box body 20, the second main body area 241 of the second folding structure 24 forms the second side wall 211 parallel to the first direction X, and the second packaging area 242 arranged around the side of the second main body area 241 can form a closed box body.

[0049] The two first clamping structures 15 are bent and connected to the two groups of first packaging areas 142 on both sides of the first main body area 141 in the first direction X, and after the first folding structure 14 is folded to form the first box body 10, the two first clamping structures 15 are arranged on different side walls of the first box body 10 in the first direction X; the two second clamping structures 25 are bent and connected to the second packaging area 242 and arranged at positions corresponding to the two first clamping structures 15, so that after the complete first box body 10 and the second box body 20 are formed, the clamping cooperation between the first clamping structure 15 and the second clamping structure 25 is realized.

[0050] As shown in Figure 5 The plate blank for forming the hidden lock type packaging box of the embodiment of the application, wherein the first main body area 141 comprises a first folding part 1411 and two second folding parts 1412 bent and connected to both sides of the first folding part 1411 in the second direction Y, the first folding part 1411 and the two second folding parts 1412 can be folded to form the first side wall 11 parallel to the first direction X, and the first folding part 1411 is provided with a third opening 16.

[0051] In specific implementation, after the first main body area 141 is folded, the two second folding parts 1412 are both connected to both sides of the first folding part 1411 in the second direction Y perpendicularly, so as to form the two first side walls 11 perpendicular to the second direction Y; the first folding part 1411 is provided with the third opening 16, so that the first opening 13 formed by folding is arranged on opposite sides, so as to push the second box body 20 through the third opening 16, and make the second box body 20 slide out of the first opening 13.

[0052] As shown in Figure 5As shown in the embodiment of this application, a blank for forming a hidden-lock packaging box includes a first encapsulation area 142 comprising a plurality of adhesive portions arranged along a second direction Y. The adhesive portions of each group of first encapsulation areas 142 are bonded together to form a first sidewall 11 perpendicular to the first direction X. A first snap-fit ​​structure 15 is bent and connected to one end of an adhesive portion corresponding to a first encapsulation area 142 in the second direction Y. After the plurality of adhesive portions of the first encapsulation area 142 are folded and bonded to form the first sidewall 11 perpendicular to the first direction X, the first snap-fit ​​structure 15 is bent to form an inwardly bent first snap-fit ​​structure 15, thereby engaging with an outwardly bent second snap-fit ​​structure 25, allowing the two to engage inside the first box body 10 to form a hidden-lock packaging box.

[0053] The first encapsulation area 142 has multiple adhesive portions, including a first adhesive portion 1421 and a second adhesive portion 1422. The first adhesive portion 1421 and the second adhesive portion 1422 are respectively bent and connected to two second folded portions 1412. The first adhesive portion 1421 also includes a first connecting portion 1423 connected to the second folded portion 1412 and a second connecting portion 1424 connected to the second folded portion 1412. The first connecting portion 1423 is positioned opposite to the second folded portion 1412 and bent and connected. The second connecting portion 1424 is positioned opposite to the first folded portion 1411 but is not connected. The second connecting portion 1424 and the second adhesive portion 1422 can be stacked on one side of the first main body area 141 and bonded together. The first connecting portion 1423 can be bonded to the first folded portion 1411. The second adhesive portion 1422 is bent and connected to the first snap-fit ​​structure 15.

[0054] like Figure 6 As shown in the embodiment of this application, the blank for forming a hidden latch-type packaging box includes a second main body area 241 comprising a third fold portion 2411 and two fourth fold portions 2412 bent and connected to the third fold portion 2411 on both sides of the second direction Y. Two second snap-fit ​​structures 25 are respectively connected to the second encapsulation areas 242 on both sides of the fourth fold portion 2412 in the first direction X.

[0055] In a specific implementation, after the second main body area 241 is folded, the two fourth folded parts 2412 are vertically connected to the third folded part 2411 on both sides of the second direction Y, thereby forming two second sidewalls 211 perpendicular to the second direction Y.

[0056] The second packaging area 242 can package the folded second main body area 241 to form the second box 20 in a closed state. Since the two second clamping structures 25 are respectively connected to the second packaging areas 242 on both sides of the fourth folding part 2412 in the first direction X, the two second clamping structures 25 can be respectively arranged on both sides of the second box 20 in the first direction X, opposite to the two first clamping structures 15 of the first box 10, so as to complete the matching arrangement between the second box 20 and the first box 10.

[0058] The second packaging area 242 comprises two third adhesive parts 2421 and two groups of fourth adhesive parts 2422. The two third adhesive parts 2421 are respectively connected to the two fourth folding parts 2412 by bending, and the two third adhesive parts 2421 can be stacked and adhered to form the second side wall 211 opposite to the third folding part 2411. The two groups of fourth adhesive parts 2422 are arranged on both sides of the second main body area 241 in the first direction X. Each group of fourth adhesive parts 2422 comprises a first sub-adhesive part 2423, a second sub-adhesive part 2424 and a third sub-adhesive part 2425. The first sub-adhesive part 2423 is connected to the third folding part 2411. The second sub-adhesive part 2424 and the third sub-adhesive part 2425 are respectively connected to the two fourth folding parts 2412. The second clamping structure 25 is connected to one side of the third sub-adhesive part 2425 close to the first sub-adhesive part 2423 by bending.

[0059] The first cover part 231 of the cover 23 can be torn and connected to the third sub-adhesive part 2425. The second cover part 232 of the cover 23 can be torn and connected to the fourth folding part 2412. The end of the second cover part 232 away from the first cover part 231 has a tear opening 233 between the second cover part 232 and the fourth folding part 2412.

[0060] The shapes of the sub-adhesive portions in the fourth adhesive portions 2422 on different sides also have differences. The first sub-adhesive portion 2423 on the upper side in the first direction X is in a rectangular structure, and the second sub-adhesive portion 2424 is also in a rectangular structure, and the length of the second sub-adhesive portion 2424 along the second direction Y is less than the length of the fourth folding portion 2412 connected thereto. When the second side wall 211 is formed by adhesive bonding, the first sub-adhesive portion 2423 and the second sub-adhesive portion 2424 are arranged in the same layer and avoid each other, and both are bonded to the third sub-adhesive portion 2425 and the cover body 23.
