Description

Technical Field

[0001] This invention relates to the field of electronic product packaging technology, and in particular to a packaging box. Background Technology

[0002] Conventional packaging for consumer electronics products typically uses simple top-and-bottom boxes, sealed with adhesive tape or heat-shrink bags to prevent product swapping. However, adhesive-sealed boxes are easily torn open in practice after being wiped with organic chemicals like alcohol. Thieves can easily replace valuable items with counterfeit goods or even take the contents and reseal the box. Heat-shrink bags, on the other hand, are difficult to counterfeit as they require tearing off the bag to open. Furthermore, with a heat-shrink machine or a powerful hot air blower, re-shrinking is both easy and inexpensive, and once re-shrinked, the evidence of swapping or theft is virtually undetectable. In other words, current packaging technology offers relatively poor anti-counterfeiting and anti-theft performance. Summary of the Invention

[0003] Therefore, it is necessary to provide a packaging box that addresses the technical problem of poor anti-counterfeiting and anti-theft performance of existing packaging boxes.

[0004] A packaging box, the packaging box comprising:

[0005] The outer box has a first cavity and a first opening connected to the first cavity. A receiving groove is provided on the outer side surface of the first side wall adjacent to the first opening. A through hole is provided on the bottom wall of the receiving groove.

[0006] Inner box, which can be accommodated within the first cavity;

[0007] The connector has one end connected to the inner box and the other end movably disposed in the receiving groove through the perforation;

[0008] A cover plate is installed and fixed to the first side wall;

[0009] A limiting member is connected to the cover plate, with one end located on the side of the cover plate away from the first side wall, and the other end located in the receiving groove to limit the end of the connector.

[0010] The limiting member and the cover plate can be operably broken apart, and then the limiting member disengages from the receiving groove.

[0011] This technical solution provides a packaging box, with the outer box forming the basic body of the entire packaging box. A first cavity is constructed on the outer box to accommodate an inner box, thereby creating a space for accommodating electronic products. The inner box can also close the first opening of the outer box. A recessed groove is provided on the outer side of the first sidewall of the outer box, allowing the end of a connector away from the inner box to be positioned within the recessed groove. A through-hole is provided on the bottom wall of the recessed groove to allow the connector to pass through. By connecting one end of the connector to the inner box and allowing the other end to pass through the through-hole and be movably positioned within the recessed groove, the connector is not constrained when the packaging box is opened, facilitating unpacking. A cover plate is placed on the first sidewall of the outer box to block the opening of the recessed groove, thereby concealing the connector. By connecting a limiting member to the cover plate, one end of the limiting member is housed within a receiving groove to limit the end of the connecting member, thereby preventing the connecting member from moving within the receiving groove and thus fixing the inner box within the first cavity of the outer box. The limiting member and the cover plate are designed to be operably detachable, allowing the limiting member to disengage from the receiving groove and thus enabling the inner box to be removed from the outer box. Since the limiting member is detached from the cover plate and cannot be restored, this effectively identifies whether the packaging box has been opened or the product has been swapped, thereby significantly reducing the risk of product tampering and enhancing the anti-counterfeiting function of the packaging box.

[0012] In one embodiment, the connector includes:

[0013] The traction body is flexibly deformable, with one end connected to the inner box and the other end passing through the perforation;

[0014] A connecting body is connected to the other end of the pulling body, the connecting body is housed in the receiving groove and is limited by the limiting member;

[0015] The connecting body is arranged perpendicular to the traction body.

[0016] In this embodiment, the connector is configured to be connected to the traction body through the connector body, and the traction body can be flexibly deformed. In this way, after the limiting body is separated from the receiving sink, the connector body can move more easily along the receiving sink under the action of external force, thereby facilitating the opening of the inner box.

[0017] In one embodiment, the inner box has a second cavity and a second opening communicating with the second cavity. The side of the inner box with the second opening is constructed as an arc surface. The inner box is rotatably disposed in the first cavity with the edge opposite to the second opening as the axis of rotation.

[0018] By constructing a second cavity on the inner box to accommodate electronic products, and by making the side of the inner box with the second opening curved, the inner box is rotatably disposed within the first cavity with the edge opposite the second opening as its axis of rotation. This allows the inner box to rotate relative to the outer box around the axis of rotation under external force when the retaining member disengages from the receiving recess, thus opening the inner box relative to the outer box. Furthermore, this configuration can also be used to display products.

[0019] In one embodiment, the number of receiving sinks is two, the two receiving sinks are spaced apart along the extension direction of the receiving sinks, a limiting rib is formed between the two receiving sinks, and the perforation is provided at the ends of the two receiving sinks that are far apart from each other.

[0020] The number of connectors is two, and the two connectors are respectively located at opposite ends of the inner box. The end of the connector away from the inner box abuts against the limiting rib, and the limiting rib limits the side of the connector away from the limiting rib.

[0021] This design limits the two connectors by the limiting ribs formed between the two receiving troughs. By setting connectors at both ends of the inner box, the two ends of the inner box are limited by the cooperation of the connectors and limiting ribs, thereby ensuring the reliability of the inner box and the outer box being relatively fixed.

[0022] In one embodiment, each of the receiving sinks is provided with a limiting protrusion that extends along the width of the receiving sink. One end of the limiting protrusion is connected to a sidewall of the receiving sink. The limiting protrusion and the limiting rib are spaced apart to define a limiting groove. One end of the connector is received in the limiting groove.

[0023] By setting a limiting protrusion on the side wall of the settling tank, a limiting groove is formed between the limiting protrusion and the limiting rib. One end of the connector is accommodated in the limiting groove, so that the connector is limited by the limiting protrusion and the limiting rib. At the same time, the reliability of limiting the connector is improved by limiting the connector, thereby improving the reliability of fixing the inner box and the outer box.

[0024] In one embodiment, the limiting member includes:

[0025] A tear strip is provided on the cover plate, and the tear strip can be separated from the cover plate under external pulling force;

[0026] The limiting body is fixedly connected to the tear strip.

[0027] The limiting component is designed with a tear-off strip and a limiting body connected together. The limiting body is connected to the tear-off strip, allowing the strip to separate from the cover when it is torn. This causes the tear-off strip to move the limiting body, disengaging it from the receiving groove. This design is simple and, once the tear-off strip is damaged, it cannot be restored, thus improving the anti-theft performance of the packaging box.

[0028] In one embodiment, the cover plate has a semi-annular through hole, the inner wall of which encloses and defines the tear strip. This design facilitates easy opening of the box by peeling off the tear strip.

[0029] In one embodiment, the limiting body abuts against the end of the connector opposite to the limiting groove. By abutting the limiting body against the end of the connector opposite to the limiting groove, the limiting protrusion and the limiting body together abut against both ends of the connector, thereby improving the limiting of the connector and ensuring the reliability of the fixation between the inner box and the outer box.

[0030] In one embodiment, the limiting rib is provided with a receiving notch corresponding to one end of the tear-off strip, and one end of the tear-off strip can be accommodated in the receiving notch. By providing a receiving notch on the limiting rib to accommodate the tear-off strip, interference between the tear-off strip and the limiting rib is prevented when the cover plate is placed on the first side wall.

[0031] In one embodiment, the cover plate is bonded to the first sidewall. Bonding the cover plate to the first sidewall simplifies the process and facilitates production; furthermore, it makes the cover plate less susceptible to being peeled off, thereby further improving anti-counterfeiting performance.

[0032] The beneficial effects of this invention are:

[0033] This invention provides a packaging box, with an outer box forming the basic body of the entire packaging box. A first cavity is constructed on the outer box to accommodate an inner box, thereby creating a space for accommodating electronic products. The inner box can also close the first opening of the outer box. A recessed groove is provided on the outer side of the first sidewall of the outer box, allowing the end of a connector away from the inner box to be positioned within the recessed groove. A through-hole is provided on the bottom wall of the recessed groove to allow the connector to pass through. By connecting one end of the connector to the inner box and movably positioning the other end through the through-hole within the recessed groove, the connector is not constrained when the packaging box is opened, facilitating unpacking. A cover plate is placed on the first sidewall of the outer box to block the opening of the recessed groove, thereby concealing the connector. By connecting a limiting member to the cover plate, one end of the limiting member is housed within a receiving groove to limit the end of the connecting member, thereby preventing the connecting member from moving within the receiving groove and thus fixing the inner box within the first cavity of the outer box. The limiting member and the cover plate are designed to be operably detachable, allowing the limiting member to disengage from the receiving groove and thus enabling the inner box to be removed from the outer box. Since the limiting member is detached from the cover plate and cannot be restored, this effectively identifies whether the packaging box has been opened or the product has been swapped, thereby significantly reducing the risk of product tampering and enhancing the anti-counterfeiting function of the packaging box.

Detailed Implementation

[0044] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0045] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0047] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0049] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0050] Conventional packaging for consumer electronics products typically uses simple top-and-bottom boxes, sealed with adhesive tape or heat-shrink bags to prevent product swapping. However, adhesive-sealed boxes are easily torn open in practice after being wiped with organic chemicals like alcohol. Thieves can easily replace valuable items with counterfeit goods or even take the contents and reseal the box. Heat-shrink bags, on the other hand, are difficult to counterfeit as they require tearing off the bag to open. Furthermore, with a heat-shrink machine or a powerful hot air blower, re-shrinking is both easy and inexpensive, and once re-shrinked, the evidence of swapping or theft is virtually undetectable. In other words, current packaging technology offers relatively poor anti-counterfeiting and anti-theft performance.

[0051] Based on this, the present invention proposes a packaging box in which the limiting member is operably broken and separated from the cover plate, allowing the limiting member to detach from the receiving groove, thereby enabling the inner box to be disassembled from the outer box. Since the limiting member is broken and separated from the cover plate and cannot be restored, this effectively identifies whether the packaging box has been opened or the product has been swapped, thus effectively reducing the risk of product swapping and improving the anti-counterfeiting function of the packaging box.

[0052] See Figures 1 to 7 As shown, one embodiment of the present invention provides a packaging box, which includes an outer box 100, an inner box 200, a connector 300, a cover plate 400, and a limiting member 500. The outer box 100 has a first cavity 110 and a first opening communicating with the first cavity 110. A receiving groove 121 is provided on the outer side surface of the first side wall 120 adjacent to the first opening of the outer box 100. A through hole 123 is provided on the bottom wall of the receiving groove 121. The inner box 200 can accommodate the first... Inside the cavity 110; one end of the connector 300 is connected to the inner box 200, and the other end passes through the through hole 123 and is located in the receiving groove 121; the cover plate 400 is covered and fixed to the first side wall 120; the limiting member 500 is connected to the cover plate 400, one end is located on the side of the cover plate 400 away from the first side wall 120, and the other end is located in the receiving groove to limit the end of the connector 300; wherein, after the limiting member 500 is operably broken and separated from the cover plate 400, the limiting member 500 is disengaged from the receiving groove.

[0053] This technical solution provides a packaging box, with an outer box 100 forming the basic body of the entire packaging box. A first cavity 110 is constructed on the outer box 100 to accommodate an inner box 200. The inner box 200 and outer box 100 together create a space for accommodating electronic products, and the inner box 200 can close the first opening of the outer box 100. A recessed groove 121 is provided on the outer side of the first sidewall 120 of the outer box 100, allowing one end of the connector 300 away from the inner box 200 to be positioned within the recessed groove 121. A through hole 123 is provided on the bottom wall of the recessed groove 121 to allow the connector 300 to pass through. By connecting one end of the connector 300 to the inner box 200 and movably positioning the other end through the through hole 123 within the recessed groove 121, the connector 300 is not constrained when the packaging box is opened, thus facilitating unpacking. By covering the first side wall 120 of the outer box 100 with a cover plate 400 to block the opening of the receiving recess 121, the connector 300 is concealed. A limiting member 500 is connected to the cover plate 400, with one end of the limiting member 500 housed within the receiving recess to limit the end of the connector 300, thereby preventing the end of the connector 300 away from the inner box from moving within the receiving recess 121, thus fixing the inner box 200 within the first cavity 110 of the outer box 100. After the limiting member 500 is operably broken apart from the cover plate 400, the limiting member 500 disengages from the receiving recess 121, allowing the inner box 200 to be removed from the outer box 100. Since the limiting component 500 has been broken and separated from the cover plate 400 and cannot be restored, this can effectively identify whether the packaging box has been opened or the product has been replaced, thereby effectively reducing the risk of product replacement and improving the anti-counterfeiting function of the packaging box.

[0054] Understandably, the outer box 100 can be rectangular in shape, with the first opening located on one side wall of the outer box 100. The first side wall 120 is adjacent to the side wall where the first opening is located. Both the outer box 100 and the inner box 200 can be made of paper or plastic. One end of the connector 300 connects to the side of the inner box 200 facing the first side wall 120, and the other end of the connector 300 is T-shaped. The cover 400 is made of paper and can be glued to the first side wall 120. Gluing the cover 400 to the first side wall 120 simplifies the process and facilitates production; furthermore, it makes the cover 400 less likely to be lifted, thus further improving its anti-counterfeiting performance.

[0055] The limiting member 500, located at the end of the cover plate 400 opposite to the first side wall 120, can be flush with the cover plate 400 or protrude from the cover plate 400. The end of the limiting member 500 facing the first side wall 120 protrudes from the side of the first side wall 120, so that after the cover plate 400 is placed on the outer box 100, the limiting member 500 can be positioned between the through hole 123 and the end of the connector 300 away from the inner box, and the limiting member 500 abuts against the end of the connector 300 away from the inner box, thereby preventing the end of the connector 300 away from the inner box from moving towards the through hole.

[0056] like Figure 3 As shown, in one embodiment, the connector 300 includes a pulling body 310 and a connecting body 320. The pulling body 310 is flexibly deformable, with one end connected to the inner box 200 and the other end passing through the through hole 123. The connecting body 320 is connected to the other end of the pulling body 310, and is housed within the receiving groove 121 and limited by the limiting member 500. The connecting body is perpendicular to the pulling body. In this embodiment, the connector 300 is configured to be connected to the pulling body 310 via the connecting body 320, and the pulling body 310 is flexibly deformable. Thus, after the limiting member 520 disengages from the receiving groove 121, an external force is applied to the inner box, causing the inner box to move the pulling body 310. This allows the connecting body 320 to move along the receiving groove 121 under the force of the pulling body, facilitating the opening of the inner box 200. By making the tension body 310 flexible and deformable, it is possible to easily change its direction, thereby allowing the connector 320 to be positioned within the receiving trough 121. The extension direction of the connector 320 is set perpendicular to the extension direction of the tension body 310, so that the connector 320 and the tension body 310 form a T-shaped structure after connection, with the length of the connector 320 greater than the width of the tension body 310. This allows the limiting body 520 to abut against the end of the connector 320 along its length, thereby limiting the connection of the connector 300.

[0057] like Figure 3 As shown, in this embodiment, the pulling body 310 is a flexible ribbon. One end of the flexible ribbon is bonded to the inner box 200, and the other end is bonded to the connecting body 320. The width of the connecting body 320 is greater than the width of the flexible ribbon, and the connecting body 320 is configured as a cuboid structure. After the cover plate 400 is placed on the outer box 100, the limiting member 500 can resist the side of the connecting body 320 away from the inner box facing the perforation 123, thereby restricting the movement of the connecting body 320 along the receiving groove 121.

[0058] like Figure 5As shown, in one embodiment, the inner box 200 is constructed with a second cavity 210 and a second opening 220 communicating with the second cavity 210. The side of the inner box 200 with the second opening 220 is constructed as an arc surface. The inner box 200 is rotatably disposed in the first cavity 110 with the edge opposite to the second opening 220 as the axis of rotation.

[0059] By constructing a second cavity 210 on the inner box 200 to facilitate the placement of electronic products, and by making the side of the inner box 200 where the second opening 220 is located curved, and by setting the inner box 200 to be rotatably disposed within the first cavity 110 with the edge opposite the second opening 220 as the axis of rotation, the inner box 200 can automatically open by rotating relative to the outer box 100 around the axis of rotation when the limiting member 500 disengages from the receiving recess 121, either under its own weight or by applying an external force. This configuration can also be used to display products.

[0060] like Figure 4 As shown, in one embodiment, there are two receiving sinks 121, which are spaced apart along the extension direction of the receiving sinks 121. A limiting rib 122 is formed between the two receiving sinks 121, and a through hole 123 is provided at the ends of the two receiving sinks 121 that are far apart from each other. There are two connecting members 300, which are respectively provided at opposite ends of the inner box 200. The end of the connecting member 300 away from the inner box 200 abuts against the limiting rib 122, and the limiting member 500 limits the side of the connecting member 300 away from the limiting rib 122.

[0061] This configuration allows the two connectors 300 to be limited by the limiting ribs 122. By providing connectors 300 at both ends of the inner box 200, the two ends of the inner box 200 are limited by the cooperation of the connectors 300 and the limiting ribs 500, thereby ensuring the reliability of the inner box 200 and the outer box 100 being relatively fixed.

[0062] Specifically, the inner box 200 is constructed in a fan shape at both ends along its length, and correspondingly, the cross-section of the inner box 200 perpendicular to its length is also fan-shaped. The inner box 200 is hollow inside, and a second opening 220 is provided on the side wall corresponding to the arc surface. When the inner box 200 is installed in the first cavity 110 of the outer box 100, the second opening 220 faces the first side wall 120. The flexible ribbons of the two connecting members 300 are provided at both ends along the length and are bonded along the circumferential edge of the arc surface. The inner box 200 can rotate relative to the outer box 100. When the limiting member 500 disengages from the receiving recess 121, the inner box 200 rotates relative to the outer box 100 under its own weight or by applying an external force. At this time, the inner box 200 pulls the connecting member 300 to move relative to the receiving recess 121, and the inner box 200 is opened.

[0063] It is understood that in this embodiment, when the inner box 200 rotates, the connecting body 320 moves along the receiving groove 121 under the action of the pulling body 310. When the connecting body 320 moves to correspond to the through hole 123, since the size of the connecting body 320 is larger than the size of the through hole 123, the connecting body 320 is limited by the hole wall of the through hole 123. Thus, the inner box 200 no longer rotates, and the inner box 200 will not separate from the outer box 100.

[0064] like Figure 8 As shown, in this embodiment, the receiving sink 121 extends along the length of the first sidewall 120, and a flat square through hole is provided at each end of the receiving sink 121. The through hole allows the flexible ribbon to pass through. The through slot is the aforementioned through hole 123. The side of the connector 320 facing away from the limiting member 500 is in contact with the limiting rib 122.

[0065] like Figure 4 and Figure 8 As shown, in one embodiment, each receiving sink 121 is provided with a limiting protrusion 1211. The limiting protrusion 1211 extends along the width direction of the receiving sink 121. One end of the limiting protrusion is connected to a side wall of the receiving sink 121. The limiting protrusion 1211 and the limiting rib 122 are spaced apart to define a limiting groove 1212. One end of the connecting body 320 along the length direction is accommodated in the limiting groove 1212.

[0066] By providing a limiting protrusion 1211 on the side wall of the receiving sink 121, a limiting groove 1212 is formed between the limiting protrusion 1211 and the limiting rib 122. One end of the connector 320 along the length direction is accommodated in the limiting groove 1212, so that the connector 320 is limited by the limiting protrusion 1211 and the limiting rib 122. At the same time, the connector 320 is limited by the limiting member 500, thereby improving the reliability of limiting the connector 320, and thus improving the reliability of fixing the inner box 200 and the outer box 100.

[0067] It is understandable that the protruding length of the limiting protrusion 1211 does not exceed one-third of the overall length of the connector 300. In this way, the limiting member 500 is abutted against the other end of the connector 320. When the limiting member 500 is disengaged from the receiving recess 121, the connector 320 can be disengaged from the limiting groove 1212 under the pull of the inner box 200, thereby being able to move relative to the receiving recess 121.

[0068] like Figure 6As shown, in one embodiment, the limiting member 500 includes a tear strip 510 and a limiting body 520. The tear strip 510 is disposed on the cover plate 400 and can be separated from the cover plate 400 under external pulling force. The limiting body 520 is fixedly connected to the tear strip 510. The limiting member 500 is configured such that the tear strip 510 and the limiting body 520 are connected together. Connecting the limiting body 520 to the tear strip 510 allows the tear strip 510 to separate from the cover plate 400 when it is torn, thereby causing the tear strip 510 to move the limiting body 520, causing the limiting body 520 to detach from the bottom wall of the receiving trough 121 away from the trough 121. This configuration is simple in structure, and the tear strip 510 cannot be restored after being damaged, thus improving the anti-theft performance of the packaging box.

[0069] In this embodiment, the tear strip 510 can be integrally formed with the cover plate 400, and the limiting body 520 can be bonded to the tear strip 510. Since the cover plate 400 is made of paper, the tear strip 510 is also made of paper. Thus, the tear strip 510 can be separated from the cover plate 400 by tearing, resulting in irreversible damage to both the tear strip 510 and the cover plate 400.

[0070] like Figure 2 and Figure 4 As shown, in one embodiment, the cover plate 400 has a semi-annular through hole 420, and the inner wall of the through hole 420 encloses and defines a tear strip 510. This arrangement ensures that the tear strip, except for the portion connected to the cover plate 400, is spaced apart from the cover plate 400 by the semi-annular through hole 420, making it easy to peel up the tear strip 510 when opening the box, thus facilitating box opening. It is understood that the semi-annular through hole 420 can be formed by punching.

[0071] In one embodiment, the limiting body 520 abuts against the end of the connector 300 opposite to the limiting protrusion 1211. By abutting the limiting body 520 against the end of the connector 300 opposite to the limiting protrusion 1211, the limiting protrusion 1211 and the limiting body 520 abut against the two ends of the connection, thereby improving the limiting of the connector 300 and ensuring the reliability of the fixation between the inner box 200 and the outer box 100.

[0072] like Figure 4As shown, in one embodiment, the limiting rib 122 is provided with a receiving notch 1221 corresponding to one end of the tear-off strip 510, and one end of the tear-off strip 510 can be received in the receiving notch 1221. By providing the receiving notch 1221 on the limiting rib 122 to receive the tear-off strip 510, interference between the tear-off strip 510 and the limiting rib 122 is prevented when the cover plate 400 is placed on the first side wall 120.

[0073] In this embodiment, the end of the tear strip 510 that is opposite to the end connected to the cover plate 400 is constructed as an arc shape. Therefore, the receiving notch 1221 on the limiting rib 122 is set as an arc shape, so that the receiving notch 1221 can limit the end of the tear strip 510.

[0074] When the packaging box provided by this invention is opened, the tear strip 510 is lifted. When the tear strip 510 separates from the cover plate 400, the limiting body 520 moves with the tear strip 510 and disengages from the receiving groove 121. At this time, the connecting body 320 is no longer limited by the limiting body 520, and the inner box 200 can rotate relative to the outer box 100. When the inner box 200 rotates, it pulls the flexible ribbon, thereby driving the connecting body 320 to move along the receiving groove 121. In this way, the inner box 200 can be opened. Since the tear strip 510 and the cover plate 400 are integrally formed, when the tear strip 510 is lifted, it is destructively separated from the cover plate 400 and cannot be restored. Thus, the anti-counterfeiting performance of the packaging box can be improved.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
