Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a tamper-proof packaging box. Background Technology

[0002] Currently, express delivery boxes generally use traditional tape sealing or tongue-and-groove fastening methods. Their structural strength is insufficient to meet the needs of complex transportation environments. During transportation, they are prone to accidental tearing and resealing after opening. This not only increases the risk of lost or damaged goods, but also makes it impossible to tell from the appearance whether the packaging has been opened because it can be easily pried open and resealed after opening. This provides an opportunity for criminals to switch or steal goods, making it difficult to guarantee the safety and integrity of transported items.

[0003] Meanwhile, during the unpacking process, recipients usually need to use tools such as scissors to open the packaging box. This unpacking method not only reduces the user experience but also poses a risk of scratching the contents and increases the possibility of the contents being stolen during the unpacking process.

[0004] Therefore, there is an urgent need to develop a tamper-proof packaging box to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-theft packaging box to enhance the overall structural strength and stability of the packaging box, prevent the packaging box from being accidentally opened in complex transportation environments, improve the anti-theft performance of the packaging box, ensure the safety and integrity of the goods during transportation, and improve the ease of opening the packaging box, reduce the risk of scratching the contents during the unpacking process, and enhance the user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An anti-theft packaging box includes a box body and a hinged lid. The box body has an opening at the top, and the hinged lid is connected to the box body and can be opened and closed to cover the opening at the top of the box body. A tear strip is processed on the hinged lid, extending through its length.

[0008] The top of the flap is connected to a plug plate, the length of which is less than the length of the flap. The plug plate has a first socket, and the box body has a plug interface. Below the plug interface is a first tongue, which includes a connected root and a barb. The root is connected to the box body. When the anti-theft packaging box is formed, the plug plate is inserted into the plug interface, the root of the first tongue is inserted into the first socket, and the barb engages with the inner wall of the plug plate.

[0009] In some alternative embodiments, the top of the first socket is machined with plug wires extending to both ends along its width direction, the plug wires being configured to allow the barb portion to pass through.

[0010] In some alternative embodiments, the two ends of the connector gradually extend upwards.

[0011] In some alternative embodiments, the width of the first socket gradually decreases from top to bottom, and the width of the base of the first tongue gradually decreases from top to bottom.

[0012] In some optional embodiments, the tamper-evident packaging box includes a first side panel, a second side panel, a third side panel, and a fourth side panel connected in sequence, which together form the receiving space of the tamper-evident packaging box. The bottom of the first side panel extends downward to a first bottom plate, the bottom of the second side panel extends downward to a second bottom plate, the bottom of the third side panel extends downward to a third bottom plate, and the bottom of the fourth side panel extends downward to a fourth bottom plate.

[0013] The second base plate is connected to a first adhesive plate, which is used to bond to the first base plate. A first crease line is formed between the first adhesive plate and the second base plate. The first crease line forms a first included angle α with the bottom edge of the second side plate, where 30°≤α≤60°.

[0014] The fourth base plate is connected to a second adhesive plate, which is used to bond with the second base plate. A second crease line is formed between the second adhesive plate and the fourth base plate. The second crease line forms a second included angle β with the bottom edge of the fourth side plate, where β = α.

[0015] In some optional embodiments, when the tamper-evident packaging box is unfolded, the first base plate and the adjacent side of the first adhesive plate form a third included angle θ, where 0 < θ ≤ 45°;

[0016] The third base plate and the adjacent side of the second adhesive plate form a fourth included angle γ, where 0 < γ ≤ 45°.

[0017] In some alternative embodiments, one side of both the first side plate and the fourth side plate is connected to a third adhesive plate, and the other side plate can be bonded to the third adhesive plate.

[0018] In some optional embodiments, the bottom of the first base plate is provided with a second tongue, and the third side plate is provided with a corresponding second slot. When the bottom of the anti-theft packaging box is formed, the second tongue is inserted into the second slot.

[0019] In some optional embodiments, the top of the second side plate extends upward with a first folding plate, the top of the first folding plate is provided with a third tongue, and the third bottom plate is provided with a corresponding third slot. The top of the fourth side plate extends upward with a second folding plate, the top of the second folding plate is provided with a fourth tongue, and the first bottom plate is provided with a corresponding fourth slot. When the bottom of the anti-theft packaging box is formed, the third tongue is inserted into the third slot, and the fourth tongue is inserted into the fourth slot.

[0020] In some optional embodiments, a cover plate extends upward from the top of the third side plate. The cover plate is used to close the top opening of the box. A fifth tongue protrudes from the top of the cover plate, and a fifth slot is correspondingly opened on the first side plate. When the tamper-evident packaging box is formed, the fifth tongue is inserted into the fifth slot.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a tamper-evident packaging box, including a box body and a hinged lid. The box body has an opening at the top, and the hinged lid is connected to the box body and can be opened and closed to cover the opening at the top of the box body. A tear strip running along the length of the hinged lid allows for quick opening of the packaging box by lightly pulling the tear strip, improving the ease of opening the packaging box and reducing the risk of scratching the contents during unpacking. A connector plate is connected to the top of the hinged lid, and the connector plate is shorter than the length of the hinged lid. A first insertion port is provided on the connector plate, and an insertion interface is provided on the box body. Below the insertion interface is a first tongue, which includes a connected root and a barb, with the root connected to the box body. When the tamper-evident packaging box is formed, the insert plate is inserted into the insert interface, and the root of the first tongue is inserted into the first insert, with the barb engaging with the inner wall of the insert plate to form a two-way self-locking structure. This achieves a secure seal between the flap and the box body, enhancing the overall structural strength and stability of the packaging box and preventing accidental opening in complex transportation environments. In addition, the root of the first tongue forms a vulnerable connection part. When normally closed, it can maintain structural strength, but when illegally pried open, it will break first from the root, damaging the integrity of the packaging and making it irreparable. This prevents others from tampering with the packaging, ensuring the safety and integrity of the goods during transportation, and achieving the effect of tamper-evident protection.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figures 1-4 As shown, this embodiment provides a tamper-evident packaging box, including a box body 1 and a hinged lid 2. The box body 1 has an opening at the top, and the hinged lid 2 is connected to the box body 1 and can be opened and closed to cover the opening at the top of the box body 1. A tear strip 21 is machined on the hinged lid 2, running through its length. Users can quickly open the packaging by simply pulling the tear strip 21. The operation is simple and effortless, and the box can be easily opened without the need for tools such as scissors, improving the convenience of opening the tamper-evident packaging box, reducing the risk of scratching the contents during the unpacking process, and improving the user experience. Furthermore, when the packaging is opened, the hinged lid 2 will completely crack along a specific path, forming an irreversible damage mark, which ensures both the convenience of opening and the anti-theft function.

[0039] The top of the flap 2 is connected to a plug plate 3. The length of the plug plate 3 is less than the length of the flap 2. The plug plate 3 has a first socket 4. The box body 1 has a plug interface 11. The plug interface 11 has a first tongue 5 below it. The first tongue 5 includes a connected root 51 and a barb 52. The root 51 is connected to the box body 1. When the anti-theft packaging box is formed, the plug plate 3 is inserted into the plug interface 11, the root 51 of the first tongue 5 is inserted into the first socket 4, and the barb 52 is engaged with the inner wall of the plug plate 3.

[0040] The plug plate 3 is inserted into the plug interface 11, and the root 51 of the first plug tongue 5 is inserted into the first plug 4. The barb part 52 is engaged with the inner wall of the plug plate 3 to form a two-way self-locking structure, which realizes the stable sealing of the flap 2 and the box body 1. Its structure is stable and not easy to loosen, which enhances the overall structural strength and stability of the anti-tamper packaging box, prevents the anti-tamper packaging box from being accidentally opened in complex transportation environments, and eliminates the need to use tape to seal the box. This not only improves the convenience of sealing the box, but also avoids tape pollution, facilitates recycling, and meets environmental protection requirements.

[0041] In addition, the root 51 of the first tongue 5 forms a weak connection part. When normally closed, it can maintain structural strength. When illegally pried, the first tongue 5 will break first from the root 51, destroying the integrity of the packaging and making it impossible to restore. This prevents others from stealing and tampering with the packaging, ensuring the safety and integrity of the goods during transportation, and achieving the effect of preventing theft and opening.

[0042] In this embodiment, the tear strip 21 is a zipper blade type. Optionally, the tear strip 21 may include, but is not limited to, a straight type or a semi-transparent tangential type, and is not limited here.

[0043] In some alternative embodiments, the top of the first socket 4 is provided with a plug wire 6 extending to both ends in the width direction. The plug wire 6 is configured to allow the barb portion 52 to pass through, so as to achieve the engagement of the first tongue 5 with the first socket 4 and prevent the first tongue 5 from coming out of the first socket 4.

[0044] In some optional embodiments, the two ends of the plug wire 6 gradually extend upward to form a sealing piece 7, which increases the passable area of ​​the barb portion 52 to facilitate the passage of the barb portion 52. Furthermore, when the barb portion 52 is inserted, the sealing piece 7 can abut against the barb portion 52 to prevent the barb portion 52 from coming out, further improving the overall structural strength and stability of the anti-theft packaging box, preventing accidental opening of the anti-theft packaging box, and ensuring that the first plug tongue 5 can break from the root 51 when illegally pried, thereby ensuring the safety and integrity of the goods during transportation.

[0045] In some optional embodiments, the width of the root 51 of the first tongue 5 gradually decreases from top to bottom, forming a V-shaped or U-shaped weak connection, thereby ensuring that the first tongue 5 breaks preferentially from the root 51 when subjected to force. The width of the first socket 4 gradually decreases from top to bottom, so that when the cover 2 moves away from the box body 1, the locking force between the first tongue 5 and the first socket 4 gradually increases, thereby preventing the first tongue 5 from coming out and ensuring that the root 51 of the first tongue 5 breaks.

[0046] In some optional embodiments, the tamper-evident packaging box includes a first side plate 8, a second side plate 9, a third side plate 10, and a fourth side plate 12 connected in sequence, which together form a receiving space for the tamper-evident packaging box. The bottom of the first side plate 8 extends downward to a first bottom plate 13, the bottom of the second side plate 9 extends downward to a second bottom plate 14, the bottom of the third side plate 10 extends downward to a third bottom plate 15, and the bottom of the fourth side plate 12 extends downward to a fourth bottom plate 16.

[0047] The second base plate 14 is connected to the first adhesive plate 17, which is used to bond with the first base plate 13. A first crease line 18 is formed between the first adhesive plate 17 and the second base plate 14. The first crease line 18 forms a first included angle α with the bottom edge of the second side plate 9, where 30°≤α≤60°. The fourth base plate 16 is connected to the second adhesive plate 19, which is used to bond with the second base plate 14. A second crease line 20 is formed between the second adhesive plate 19 and the fourth base plate 16. The second crease line 20 forms a second included angle β with the bottom edge of the fourth side plate 12, where β=α.

[0048] In some alternative embodiments, one side of the first side plate 8 and the fourth side plate 12 is connected to a third adhesive plate 22, and the other side plate 12 can be bonded to the third adhesive plate 22.

[0049] like Figure 2 and Figure 3 As shown, by applying adhesive to the first adhesive plate 17, the second adhesive plate 19, and the third adhesive plate 22, and then bonding the first adhesive plate 17 to the first base plate 13, the second adhesive plate 19 to the second base plate 14, and the third adhesive plate 22 to the first side plate 8 or the fourth side plate 12, the anti-theft packaging box can be pre-formed, allowing it to be folded flat for easy stacking and transportation. When items need to be placed inside, it can be assembled, effectively saving warehousing and transportation costs and preventing the anti-theft packaging box from being squeezed and deformed, thus ensuring the integrity of the anti-theft packaging box.

[0050] The first fold line 18 forms a first angle α with the bottom edge of the second side plate 9, where 30°≤α≤60°. The second fold line 20 forms a second angle β with the bottom edge of the fourth side plate 12, where β=α. When the anti-theft packaging box is folded, the first adhesive plate 17 and the second bottom plate 14 are folded along the first fold line 18, and the second adhesive plate 19 and the fourth bottom plate 16 are folded along the second fold line 20. This helps to improve folding efficiency and ensures the aesthetics of the bottom of the anti-theft packaging box, avoiding deformation of the bottom caused by free folding.

[0051] In this embodiment, β = α = 45°. Optionally, depending on the size of the tamper-evident packaging box, β and α may be, but are not limited to, 30° or 60°, and are not limited here.

[0052] In some optional embodiments, when the tamper-evident packaging box is unfolded, the adjacent sides of the first base plate 13 and the first adhesive plate 17 form a third included angle θ, 0<θ≤45°, and the adjacent sides of the third base plate 15 and the second adhesive plate 19 form a fourth included angle γ, 0<γ≤45°. This can avoid excessive local thickness when folding, which is beneficial to improving the flatness of the tamper-evident packaging box when folded and preventing deformation of the bottom of the tamper-evident packaging box.

[0053] In this embodiment, θ is 10° and γ is 15°. Optionally, θ may include, but is not limited to, 2°, 5°, 15°, 35°, or 45°. Optionally, γ may include, but is not limited to, 2°, 5°, 15°, 35°, or 45°.

[0054] In some optional embodiments, the bottom of the first base plate 13 is provided with a second tongue 23, and the third side plate 10 is provided with a corresponding second slot 24. When the bottom of the anti-theft packaging box is formed, the second tongue 23 is inserted into the second slot 24. When it is necessary to put in an item, the folded anti-theft packaging box is unfolded and the second tongue 23 is inserted into the second slot 24. This can conveniently and quickly form the bottom of the anti-theft packaging box. After the item is put in, the supporting effect of the item can prevent the anti-theft packaging box from folding, thereby further improving the structural stability of the bottom of the anti-theft packaging box.

[0055] In some optional embodiments, a first folding plate 25 extends upward from the top of the second side plate 9, and a third tongue 26 protrudes from the top of the first folding plate 25. A third slot 27 is correspondingly provided on the third bottom plate 15. A second folding plate 28 extends upward from the top of the fourth side plate 12, and a fourth tongue 29 protrudes from the top of the second folding plate 28. A fourth slot 30 is correspondingly provided on the first bottom plate 13. When the bottom of the anti-theft packaging box is formed, the third tongue 26 is inserted into the third slot 27, and the fourth tongue 29 is inserted into the fourth slot 30, which further fixes the first bottom plate 13 and the third bottom plate 15, improving the structural stability of the bottom of the anti-theft packaging box. Furthermore, the first folding plate 25 and the second folding plate 28 are folded downward along the preset fold lines, so that the two side plates of the anti-theft packaging box form a double-layer structure, which can improve the overall structural strength and stability of the anti-theft packaging box.

[0056] In some optional embodiments, a cover plate 31 extends upward from the top of the third side plate 10. The cover plate 31 is used to close the top opening of the box body 1. A fifth tongue 32 protrudes from the top of the cover plate 31, and a corresponding fifth slot 33 is provided on the first side plate 8. When the tamper-evident packaging box is formed, the fifth tongue 32 is inserted into the fifth slot 33. The cover plate 31 and the hinged cover 2 form a double seal on the top opening of the box body 1, which can further improve the sealing effect of the items inside the tamper-evident packaging box and prevent the items from being accidentally lost, damaged, replaced, or stolen.

[0057] It should be noted that each connected panel has a crease line. Folding the panels along the pre-set crease line allows for quick and accurate assembly of the tamper-evident packaging box.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
