These figures and the written description are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in more detail hereinafter with reference to the accompanying drawings.

[0035] In the related art, packaging boxes (for example, take-out paper boxes) are mostly used once and do not need to be opened and closed repeatedly. However, the existing food packaging paper boxes can be opened and closed repeatedly, and cannot identify whether they are opened in the delivery process from the merchant to the customer, and cannot prevent the hygiene and safety of the food in the packaging paper box.

[0036] Please refer to Figs. 1, 2 and 3, Fig. 1 is a structural schematic view of a tamper-evident box in an open state according to an embodiment of the present application, Fig. 2 is a structural schematic view of a tamper-evident box in a closed state according to an embodiment of the present application, and Fig. 3 is an effect schematic view of a tamper-evident box in an unfolded state according to an embodiment of the present application. The tamper-evident box 000 can include a bottom shell 100 and a top cover 200.

[0037] The bottom shell 100 in the tamper-evident box 000 can have a first side plate 101 and a second side plate 102 arranged oppositely, and a receiving cavity a1 distributed between the first side plate 101 and the second side plate 102, and the second side plate 102 can have a limiting insertion hole b1. For example, the limiting insertion hole b1 in the second side plate 102 can be in communication with the receiving cavity a1.

[0038] The first end of the top cover 200 in the tamper-evident box 000 can be movably connected with the first side plate 101, and the second end of the top cover 200 can have an insert 201 and a first inner end plate 202 arranged adjacently, and the maximum width of the insert 201 can be greater than or equal to the maximum width of the limiting insertion hole b1 in the second side plate 102. It should be noted that the first end and the second end of the top cover 200 can be two ends arranged oppositely.

[0039] When the anti-disassembly box 000 is in the closed state, at least part of the first inner end plate 202 can be arranged opposite to the second side plate 102 in the accommodating cavity a1 in the bottom shell 100. The first inner end plate 202 can be in contact with the second side plate 102, and part of the insert 201 can be inserted into the limiting insertion hole b1 and be clamped with the second side plate 102. As shown in FIG. 3, the anti-disassembly box 000 can be folded and assembled from the unfolded state. When the anti-disassembly box 000 is in the closed state, the top cover 200 can be used to cover the cavity a1 in the bottom shell 100.

[0040] In the embodiment of the present application, the limiting insertion hole b1 is arranged in the second side plate 102 of the bottom shell 100, and the second end of the top cover 200 is provided with the insert 201 matched with the limiting insertion hole b1. Thus, in the process of closing the top cover 200 and the bottom shell 100, the insert 201 can be deformed and inserted into the limiting insertion hole b1 from the opening area of the limiting insertion hole b1 and be clamped with the second side plate 102, so that the insert 201 is not easily pulled out under the action of external force. If the insert 201 is forcibly pulled out of the limiting insertion hole b1, the insert 201 or the opening area of the limiting insertion hole b1 will be damaged, so as to be recognized by the user, that is, the anti-disassembly box 000 can effectively recognize whether it is disassembled, has good safety performance, and effectively improves the user experience. In addition, after the top cover 200 and the bottom shell 100 are closed, the first inner end plate 202 can be arranged opposite to the second side plate 102 in the accommodating cavity a1 and be in contact with each other, which effectively improves the overall support effect of the anti-disassembly box 000 and the sealing effect of the accommodating cavity a1.

[0041] In summary, the embodiment of the present application provides an anti-disassembly box, which can include a bottom shell and a top cover. By arranging a limiting insertion hole in the second side plate of the bottom shell, the second end of the top cover is provided with an insert matched with the limiting insertion hole. Thus, in the process of closing the top cover and the bottom shell, the insert can be deformed and inserted into the limiting insertion hole from the opening area of the limiting insertion hole and be clamped with the second side plate, so that the insert is not easily pulled out under the action of external force. If the insert is forcibly pulled out of the limiting insertion hole, the insert or the opening area of the limiting insertion hole will be damaged, so as to be recognized by the user, that is, the anti-disassembly box can effectively recognize whether it is disassembled, has good safety performance, and effectively improves the user experience. In addition, after the top cover and the bottom shell are closed, the first inner end plate can be arranged opposite to the second side plate in the accommodating cavity and be in contact with each other, which effectively improves the overall support effect of the anti-disassembly box and the sealing effect of the accommodating cavity.

[0042] In the embodiment of the present application, the anti-disassembly box 000 can be a square paper box. It should be noted that the anti-disassembly box 000 can also be a box body made of other materials, which is not limited in the embodiment of the present application.

[0043] Optionally, one end of the first inner end plate 202 in the top cover 200 towards the bottom wall of the accommodating cavity a1 in the bottom shell 100 can be in contact with the bottom wall of the accommodating cavity a1. In this case, by setting the one end of the first inner end plate 202 towards the bottom wall of the accommodating cavity a1 in contact with the bottom wall a1 of the accommodating cavity of the bottom shell 100, thus effectively improving the overall structural strength of the anti-disassembly box 000, avoiding the adverse phenomenon that the top cover 200 is easy to deform and collapse under the action of external force. For example, the height of the first inner end plate 202 can be the same as the depth of the accommodating cavity a1 in the bottom shell 100.

[0044] In the embodiment of the present application, please refer to FIG. 4, which is a structural schematic diagram of another anti-disassembly box in the closed state provided by the embodiment of the present application.

Wherein, the top cover 200 can have a flat state and a bent state, when the top cover 200 is in the flat state, the first inner end plate 202 can be flush with the top cover body 203, and the insert 201 can be distributed between the first inner end plate 202 and the top cover body 203. When the top cover 200 is in the bent state, the first inner end plate 202 can intersect with the top cover body 203. In this case, by setting the weak connection part 204 between the insert 201 and the top cover body 203, when the user normally disassembles the anti-disassembly box 000, the pressure can be applied to the insert 201 towards the direction of the accommodating cavity a1, so that the insert 201 and the top cover body 203 are disconnected at the weak connection part 204, thereby realizing the separation of the top cover 200 and the bottom shell 100.

[0045] The weak connection part 204 in the embodiment of the present application has various optional implementation manners, and the present application will be illustratively described by taking the following two optional implementation manners as examples:

In this case, by arranging the hollow holes 204a and the connecting pieces 204b to be distributed at intervals in the weak connection part 204, the insert 201 and the top cover body 203 can be disconnected at the weak connection part 204 during the user applying pressure to the insert 201, so as to realize the separation of the insert 201 and the top cover body 203.

[0047] In the second optional implementation, the thickness of the weak connection part 204 can be less than the thickness of the top cover body 203 and less than the thickness of the insert 201. In this case, by arranging the thickness of the weak connection part 204 to be less than the thickness of the top cover body 203 and less than the thickness of the insert 201, the insert 201 and the top cover body 203 can be disconnected at the weak connection part 204 during the user applying pressure to the insert 201, so as to realize the separation of the insert 201 and the top cover body 203.

[0048] It should be noted that in other optional implementations, the weak connection part 204 can include a plurality of hollow holes 204a and a plurality of connecting pieces 204b. The connecting pieces 204b can be fixedly connected with the top cover body 203 and the insert 201 respectively, and at least one hollow hole 204a can be distributed between every two adjacent connecting pieces 204b. The thickness of the connecting pieces 204b can be less than the thickness of the top cover body 203 and less than the thickness of the insert 201.

[0049] Optionally, please refer to FIG. 6 and FIG. 7, FIG. 6 is a front view of the anti-disassembly box in the open state, and FIG. 7 is a front view of the anti-disassembly box in the closed state.

One end of the limiting portion 201b can be fixedly connected to the end of the transition connecting portion 201c away from the top cover body 203. The insertion portion 201a can be fixedly connected to one end of the limiting portion 201b away from the transition connecting portion 201c. The width of the limiting portion 201b can be greater than the width of the insertion portion 201a and greater than the width of the transition connecting portion 201c. The opening area of the limiting insertion hole b1 in the second side plate 102 can include a flared area b11 and a limiting opening area b12 that are in communication with each other. The flared area b11 of the limiting insertion hole b1 can be arranged opposite to the first inner end plate 202, and the limiting opening area b12 of the limiting insertion hole b1 can be arranged intersecting the flared area b11. The width of the flared area b11 of the limiting insertion hole b1 gradually decreases in the direction approaching the limiting opening area b12 of the limiting insertion hole b1, and the width of the flared area b11 of the limiting insertion hole b1 can be greater than the width of the limiting opening area b12 of the limiting insertion hole b1.
