Description

Technical Field

[0001] This disclosure relates to the field of packaging technology, and more particularly to a packaging box. Background Technology

[0002] In a global packaging industry increasingly focused on user experience and environmental protection, the European EAA regulations have set stringent standards for the ease of opening packaging. These regulations explicitly require packaging to significantly reduce the difficulty of opening while ensuring anti-theft functionality, thus meeting consumer needs and complying with regulations. This regulation not only concerns user experience but also represents a comprehensive consideration of packaging structural design, functionality, and environmental attributes.

[0003] The direct-insertion snap-fit ​​structure is a common packaging connection method. Its main feature is that the packaging is closed by directly inserting a tongue into a corresponding slot. Specifically, during packaging manufacturing, tongues and slots are pre-drilled in different parts of the packaging. When sealing the packaging, simply align the tongue accurately with the slot and insert it firmly to complete the seal. However, because it relies solely on the simple cooperation of the tongue and slot, its anti-theft performance is relatively weak. Summary of the Invention

[0004] This disclosure provides a packaging box to at least solve the above-mentioned technical problems existing in the prior art.

[0005] This disclosure provides a packaging box, comprising:

[0006] The box body forms a receiving body with an opening, and the receiving body is provided with a first snap-fit ​​portion;

[0007] A cover plate is provided on the opening and is rotatably connected to the box body. The cover plate is provided with a second snap-fit ​​part, which engages with the first snap-fit ​​part.

[0008] An adhesive component includes a first part and a second part, the first part being connected to the housing and the second part being connected to the cover plate, the adhesive component including a glue-free area located at the edge of the first part or the second part;

[0009] Wherein, when the glue-free area is located at the edge of the first part, the first part covers the outer surface of the box body, and when the glue-free area is located at the edge of the second part, the second part covers the outer surface of the cover plate.

[0010] Furthermore, the housing includes a first side panel, with a first extension plate and a bottom plate connected to its two ends respectively. A first crease line is formed between the first extension plate and the first side panel. A slot is provided at the end of the first extension plate near the first side panel, and a first snap-fit ​​part is provided on the first side panel.

[0011] The cover plate includes a panel, one end of which is rotatably connected to the housing, and the other end is provided with a second extension plate. A second fold line is provided between the second extension plate and the panel. A second snap-fit ​​part is provided on the second extension plate, and the second extension plate is inserted into the slot.

[0012] The first part is connected to the first side panel, and the second part is connected to the outer surface of the panel, with the glue-free area located at the edge of the second part; or, the second part is connected to the panel, the first part is connected to the outer surface of the first side panel, and the glue-free area is located at the edge of the first part.

[0013] Furthermore, the first side plate has an opening portion, the first snap-fit ​​portion is disposed in the opening portion, and the first portion is connected to the opening portion.

[0014] Furthermore, the first side panel is provided with a first tear line and a second tear line, which are spaced apart. Both the first tear line and the second tear line extend from the slot toward the base plate, so that the opening portion is formed in the area between the first tear line and the second tear line of the first side panel.

[0015] Furthermore, both the first and second tear lines have multiple spaced connection points.

[0016] Furthermore, the first snap-fit ​​portion includes a first barb located on the surface of the first side plate facing the second extension plate;

[0017] The second snap-fit ​​portion includes a second barb located on the surface of the second extension plate facing the first side plate;

[0018] The first barb and the second barb are inserted into each other.

[0019] Furthermore, the first snap-fit ​​portion includes a third extension plate, which is disposed in the opening portion and extends from the opening portion toward the base plate to form the first barb;

[0020] The second snap-fit ​​portion includes a fourth extension plate that extends from the second extension plate toward a direction close to the second crease line to form the second barb.

[0021] Furthermore, a pre-folding hole is provided between the second extension plate and the panel, and the pre-folding hole is located at the second fold line.

[0022] Furthermore, the housing includes a second side panel, and a third crease line is formed between the front panel and the second side panel;

[0023] The panel is stacked on top of the first extension plate;

[0024] Wherein, along the height direction Z of the box body, the height difference between the third crease line and the first crease line is less than the sum of the thicknesses of the panel and the first extension plate.

[0025] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0026] The packaging box provided in this embodiment includes a box body, a cover, and an adhesive component. It forms a receiving body with an opening, and the receiving body has a first snap-fit ​​portion. The cover covers the opening and is rotatably connected to the box body. The cover has a second snap-fit ​​portion that engages with the first snap-fit ​​portion. The adhesive component includes a first part and a second part. The first part is connected to the box body, and the second part is connected to the cover. The adhesive component includes a non-adhesive area located at the edge of either the first or second part. When the non-adhesive area is located at the edge of the first part, the first part covers the outer surface of the box body; when the non-adhesive area is located at the edge of the second part, the second part covers the outer surface of the cover. The snap-fit ​​between the first and second snap-fit ​​portions establishes a stable mechanical locking system. Unlike traditional complex double-latch operations, users only need to apply moderate external force to open the cover, significantly reducing the difficulty of opening. Furthermore, the first and second parts of the adhesive component, connected to the box body and the cover, form an additional protective barrier, making it difficult to separate and open without damage, effectively preventing unauthorized unpacking. The first and second parts are designed to be separable and bonded to the outer surface of the box or cover via adhesive-free areas. When disassembly is needed, they can be quickly torn apart through these adhesive-free areas, improving ease of opening. This design ensures product safety while avoiding the risk of scratches from using tools such as blades, achieving a balance between ease of opening and anti-theft performance.

[0034] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0035] Combination Figure 1 , Figure 2 and Figure 3 As shown, the packaging box provided in this embodiment includes a box body 1, a cover plate 2, and an adhesive component 3; it forms a receiving body with an opening, and the receiving body is provided with a first snap-fit ​​portion; the cover plate 2 covers the opening and is rotatably connected to the box body 1, and the cover plate 2 is provided with a second snap-fit ​​portion, which engages with the first snap-fit ​​portion; the adhesive component 3 includes a first part 31 and a second part 32, the first part 31 is connected to the box body 1, the second part 32 is connected to the cover plate 2, and the adhesive component 3 includes a non-adhesive area 33, which is located at the edge of the first part 31 or the second part 32; wherein, when the non-adhesive area 33 is located at the edge of the first part 31, the first part 31 covers the outer surface of the box body 1, and when the non-adhesive area 33 is located at the edge of the second part 32, the second part 32 covers the outer surface of the cover plate 2.

[0036] The interlocking of the first and second latching parts creates a stable mechanical locking system. Unlike traditional complex double-latch operations, users only need to apply moderate external force to open the cover 2, significantly reducing the difficulty of opening. The first part 31 and the second part 32 of the adhesive component 3 connect to the box body 1 and the cover 2, forming an additional protective barrier that is difficult to separate without damage, effectively preventing unauthorized opening. The first part 31 and the second part 32 form a separable adhesive design with the outer surface of the box body 1 or the outer surface of the cover 2 through the adhesive-free area 33. When disassembly is needed, it can be quickly torn apart through the adhesive-free area 33, improving the ease of opening. While ensuring the safety of the goods, it avoids the risk of scratches from using blades or other tools, achieving a balance between ease of opening and anti-theft performance.

[0037] The packaging box features a simple and standardized structural design, making it easier to integrate with automated packaging equipment compared to traditional irregularly shaped tongue structures. During the production assembly process, the standardized snap-fit ​​method between the first and second snap-fit ​​parts, as well as the bonding operation of adhesive component 3, can all be completed quickly and accurately by automated equipment, effectively improving production efficiency.

[0038] Optionally, the adhesive 3 can be tape, a label, or other flexible patch.

[0039] In some specific embodiments, the box body 1 includes a first side panel 11, with a first extension plate 13 and a bottom plate 16 connected to its two ends respectively. A first crease line 15 is formed between the first extension plate 13 and the first side panel 11, serving as a stress concentration guide path to ensure accurate folding angles, neat shaping, and improved overall structural stability of the packaging box. A slot 14 is provided at the end of the first extension plate 13 near the first side panel 11, and a first snap-fit ​​part is provided on the first side panel 11. The cover 2 includes a panel 21, one end of which is rotatably connected to the box body 1, and the other end is provided with a second extension plate 22. A second crease line 23 is provided between the second extension plate 22 and the panel 21, reducing the force required for users to fold and open the packaging, making it easy for the elderly or children to operate. The rotatable connection between the cover 2 panel 21 and the box body 1, combined with the bending guidance of the second extension plate 22 by the second crease line 23, makes the opening and closing of the cover 2 smooth and natural, allowing users to complete the opening action with only one hand.

[0040] The second latching part is disposed on the second extension plate 22, and the second extension plate 22 is inserted into the slot 14. The insertion and engagement of the second extension plate 22 and the slot 14, as well as the mechanical locking of the first latching part and the second latching part, constitute a multi-layer anti-theft system. The first part 31 is connected to the first side plate 11, and the second part 32 is connected to the outer surface of the panel 21, with the adhesive-free area 33 located at the edge of the second part 32; or, the second part 32 is connected to the panel 21, and the first part 31 is connected to the outer surface of the first side plate 11, with the adhesive-free area 33 located at the edge of the first part 31. The first part 31 and the second part 32 of the adhesive 3 are connected to the first side plate 11 and the panel 21, forming an additional protective barrier that is difficult to separate and open without damage, effectively preventing unauthorized opening. The first part 31 and the second part 32 are separated from the outer surface of the first side plate 11 or the outer surface of the panel 21 through the adhesive-free area 33, forming a separable adhesive design. When it is necessary to open, it can be quickly torn apart through the adhesive-free area 33, improving the convenience of opening.

[0041] This embodiment can effectively prevent goods from being illegally opened during the distribution process, while avoiding the inconvenience and risks of traditional sealing methods that require tools to open.

[0042] In some specific embodiments, the first side plate 11 has an opening portion 113, a first snap-fit ​​portion is disposed in the opening portion 113, and a first part 31 is connected to the opening portion 113. The design of the opening portion 113 of the first side plate 11 concentrates the first snap-fit ​​portion here, forming a clear force application area, which allows the user to apply force precisely and avoids the opening difficulties caused by the ambiguity of the force application point in traditional distributed snap-fit ​​structures.

[0043] In some specific embodiments, the first side plate 11 is provided with a first tear line 111 and a second tear line 112, the first tear line 111 and the second tear line 112 are spaced apart, and both the first tear line 111 and the second tear line 112 extend from the slot 14 toward the direction close to the bottom plate 16, so that the area of ​​the first side plate 11 between the first tear line 111 and the second tear line 112 forms an opening portion 113.

[0044] In some specific embodiments, both the first tear line 111 and the second tear line 112 have multiple spaced connection points, forming an alternating "weakening-connection" structure that effectively controls the tearing path and force. When the user applies force, the tear line will tear in an orderly manner along the preset gaps between the connection points, avoiding the breakage or incomplete tearing problems caused by stress concentration in traditional tear lines, ensuring a smooth and controllable opening process.

[0045] In some specific embodiments, the first locking part includes a first barb 114 located on the surface of the first side plate 11 facing the second extension plate 22; the second locking part includes a second barb 221 located on the surface of the second extension plate 22 facing the first side plate 11; the first barb 114 and the second barb 221 are interlocked. The mutual engagement of the first barb 114 and the second barb 221 forms an irreversible mechanical locking structure, which is difficult to pry open or separate from the outside by external force compared to traditional straight-insertion or press-fit buckles. When the cover plate 2 is closed, the inclined surface of the barb guides it to automatically engage with the corresponding groove, forming a tight fit; if it needs to be opened, force must be applied from a specific direction to break the locking state, greatly increasing the difficulty of illegal opening and providing reliable anti-theft protection for high-value goods. At the same time, the barb structure is not easy to loosen under normal transportation vibration environment, avoiding accidental opening of the packaging due to accidental contact, and ensuring the safety of goods in the circulation process.

[0046] In some specific embodiments, the first engaging portion includes a third extension plate disposed on the opening portion 113, and the third extension plate extends from the opening portion 113 toward the base plate 16 to form a first barb 114; the second engaging portion includes a fourth extension plate, the fourth extension plate extending from the second extension plate 22 toward the second crease line 23 to form a second barb 221. During the closing process of the cover plate 2, the user does not need precise alignment, and can quickly and smoothly complete the engaging process simply by relying on the guidance of the third and fourth extension plates; when opening, the barbs can be separated by applying a small torque, further reducing the force required for opening.

[0047] In some specific embodiments, a pre-folding hole 24 is provided between the second extension plate 22 and the panel 21, and the pre-folding hole 24 is located at the second fold line 23. During the folding process, the pre-folding hole 24 guides the second extension plate 22 to bend precisely along the second fold line 23, avoiding folding deviations caused by the springback or deformation of the second extension plate 22, and ensuring that the cover plate 2 is formed neatly.

[0048] In some specific embodiments, the box body 1 includes a second side panel 12, and a third fold line is formed between the front panel 21 and the second side panel 12; the front panel 21 and the first extension plate 13 are stacked; wherein, along the height direction Z of the box body 1, the height difference between the third fold line and the first fold line 15 is less than the sum of the thicknesses of the front panel 21 and the first extension plate 13. This allows the cardboard of the front panel 21 to form an elastic potential energy reserve in the folded state. When the opening part 113 is opened, at the instant the first and second latching parts are unlocked, the compressed front panel 21 generates a deformation recovery force due to the rebound force, driving the front panel 21 to automatically pop open. Compared with the traditional packaging method that requires manually lifting the cover 2, this design transforms the mechanical properties of the material into a functional structure, significantly improving the convenience and fun of opening the packaging for users, and is especially suitable for the ritualistic experience requirements of high-end products.
