Description

Technical Field

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

[0002] During product packaging, logistics, and use, the contents are susceptible to damage from collisions, compression, and shrinkage during the sealing process of the protective film, which can cause dents. To prevent damage to items inside the packaging box due to collisions and compression, dividers are usually installed inside the box to separate and position the items. Currently, most common packaging box dividers are made of one-piece cardboard or simple insert structures. However, most of these dividers lack a reliable fixing structure and only maintain their position through the contact friction between themselves and the inner wall of the packaging box. During transportation, handling, or when inserting the inner box into the outer box, they are easily displaced by external forces, which can compress the contents and cause them to be misplaced, affecting the appearance. Secondly, although some insert-type dividers have inserts, these inserts are mostly vertically positioned, resulting in insufficient stability after insertion, and the inserts protrude outside the box, affecting the appearance.

[0003] In summary, existing packaging box dividers, due to the lack of a fixed structure, cannot effectively prevent the dividers from moving left and right inside the box, thus failing to meet the need for stable protection of the items inside. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a packaging box blocking device, including a blocking body, on which at least one positioning tongue is symmetrically arranged on each side, and the tongue is used to be detachably inserted into the insertion hole on the side wall of the packaging box.

[0005] Furthermore, the main body of the barrier also includes a main body partition plate and two side connecting plates; The side connecting plates are respectively perpendicularly connected to the two opposite long edges of the main body partition plate; The positioning tongues are vertically connected to the two opposite short edges of the main body partition plate, and are used to cooperate with the insertion holes on the side wall of the packaging box to achieve positioning.

[0006] Furthermore, it also includes at least one partition wing plate, one side edge of which is vertically connected to the edge of the side connecting plate away from the main partition plate.

[0007] Furthermore, there are two partition wing plates, one side edge of each of the two partition wing plates is perpendicularly connected to the edge of the two side connecting plates away from the main partition plate, and the two partition wing plates are symmetrically arranged with respect to the longitudinal central axis of the main partition plate.

[0008] Furthermore, the positioning tongue extends vertically downward from the short edge of the main body partition plate.

[0009] Furthermore, the two side connecting plates are symmetrically arranged relative to the longitudinal central axis of the main body partition plate.

[0010] Furthermore, the main partition plate, positioning tongue, side connecting plate and partition wing plate are integrally formed structures, and the upper edge of the partition body is pre-formed with creases at the connection between the side connecting plate, positioning tongue and partition wing plate to achieve folding.

[0011] This utility model also provides a packaging box, in which a packaging box blocking device as described above is provided, and the two side walls of the packaging box are provided with insertion holes, into which the positioning tongue of the packaging box blocking device is inserted.

[0012] Furthermore, the insertion holes are respectively opened on two opposite inner sidewalls of the packaging box, and the insertion holes on the two inner sidewalls are symmetrically distributed; The insertion hole is a horizontal insertion hole, and the positioning tongue extends vertically downward from the short edge of the main body partition plate and is inserted into the horizontal insertion hole.

[0013] Furthermore, the packaging box also includes a lid.

[0014] Compared with existing technologies, the packaging box blocking device provided by this utility model, by symmetrically setting positioning tongues on both sides of the blocking body, allows it to be directly inserted into the reserved holes on the side wall of the packaging box, forming a mechanical interlock. This structure can effectively limit the lateral or longitudinal movement of the blocking device inside the packaging box, solving the problem of easy displacement of traditional blocking devices that rely solely on friction for fixation, and ensuring that the contents always remain stable. When the packaging box lid is pressed from above, the engagement of the positioning tongues and the holes forms a stable connection between the blocking body and the side wall of the packaging box. The blocking body can bear part of the vertical pressure with the cooperation strength of the tongues and the holes, forming a support structure along the height of the packaging box. This support structure can directly block the pressure of the lid from being transmitted to the contents inside the box, preventing the contents from being squeezed, deformed, or damaged due to pressure from the top. It is especially suitable for the protection of fragile and easily deformable items. The blocking device has a simple structure, and its modular design allows it to flexibly adapt to the inner cavity of various packaging boxes of different sizes and shapes, making it highly versatile.

[0015] The packaging box provided by this utility model integrates the above-mentioned partition device into the packaging box and precisely matches it with the insertion hole on the box wall to form a stable internal partition system. The packaging box can effectively isolate and independently limit multiple items inside, significantly reducing the risk of collision damage caused by shaking and squeezing.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They 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, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] To address the problem that existing packaging box dividers, lacking a fixed structure, cannot effectively prevent lateral movement within the box, thus failing to meet the need for stable protection of the items inside, this utility model provides... Figure 1-4The packaging box divider and packaging box are shown.

[0022] like Figure 1-2 As shown, the packaging box blocking device includes a blocking body 1, and at least one positioning tongue 2 is symmetrically arranged on both sides of the blocking body 1. The positioning tongue 2 is used to be detachably inserted into the insertion hole 7 on the side wall of the packaging box 6.

[0023] Understandably, the packaging box blocking device uses symmetrically arranged positioning tongues 2 on both sides of the blocking body 1, which can be directly inserted into the reserved insertion holes 7 on the side wall of the packaging box 6 to form a reliable mechanical interlock. This structure can effectively limit the blocking device from moving laterally or longitudinally inside the packaging box 6, and completely solves the problem that traditional blocking devices are easily displaced due to relying solely on friction for fixation, ensuring that the contents always remain stable.

[0024] In one embodiment, such as Figure 2 As shown, the main body of the barrier 1 also includes a main body partition plate 3 and two side connecting plates 4; The side connecting plate 4 is perpendicularly connected to the two opposite long edges of the main body partition plate 3. The positioning tongues 2 are vertically connected to the two opposite short edges of the main body partition plate 3, and are used to cooperate with the insertion holes 7 on the side wall of the packaging box 6 to achieve positioning.

[0025] In the above scheme, by setting the main partition plate 3 and the vertically connected side plate 4, a sturdy "U"-shaped frame structure is formed, which significantly improves the overall rigidity and compressive strength of the blocking device and can withstand greater external impact. In addition, the main partition plate 3 realizes the core separation function, and the positioning tongue 2 is directly connected to its short edge, so that the positioning point directly acts on both ends of the partition plate, the force transmission path is more direct, and further enhances the overall stability inside the packaging box 6.

[0026] In one embodiment, such as Figure 2 As shown, it also includes at least one partition wing plate 5, one side edge of which is vertically connected to the edge of the side connecting plate 4 away from the main partition plate 3.

[0027] By adopting the above scheme, the stability of the main body of the barrier is further enhanced by adding a partition wing plate 5.

[0028] In one embodiment, such as Figure 2 As shown, there are two partition wing plates 5. One side edge of each of the two partition wing plates 5 is perpendicularly connected to the edge of the two side connecting plates 4 away from the main partition plate 3, and the two partition wing plates 5 are symmetrically arranged with respect to the longitudinal central axis of the main partition plate 3.

[0029] Understandably, the symmetrical arrangement of the two dividing wing plates 5 makes the force on the blocking device more balanced within the packaging box 6, avoiding the torsional force caused by structural asymmetry, thereby improving the overall stability and load-bearing capacity.

[0030] In one embodiment, such as Figure 2 As shown, the positioning tongue 2 extends vertically downward from the short edge of the main body partition plate 3. When the positioning tongue 2 extends vertically downward, it provides a natural insertion guide when it cooperates with the transverse insertion hole 7 on the side wall of the packaging box 6, making the assembly process smoother and more accurate. In addition, the positioning tongue 2 inserts downward into the side wall, so that the fixing structure is completely hidden inside the box body, and will not affect the overall appearance of the packaging box 6 like the exposed insert.

[0031] In one embodiment, such as Figure 2 As shown, the two side connecting plates 4 are symmetrically arranged with respect to the longitudinal central axis of the main body partition plate 3.

[0032] In one embodiment, such as Figure 1 As shown, the main partition plate 3, the positioning tongue 2, the side connecting plate 4 and the partition wing plate 5 are integrally formed structures. The upper edge of the main partition plate 1 is pre-formed with creases at the connection between it and the side connecting plate 4, the positioning tongue 2 and the partition wing plate 5 to achieve folding.

[0033] Specifically, in use, take out the one-piece molded barrier device in its initial flat state, fold the two side connecting plates 4 toward the same side of the main partition plate 3 along the preset creases, so that the side connecting plates 4 are perpendicular to the main partition plate 3, and fold the partition wing plate 5 away from the main partition plate 3 along the creases on the edge of the side connecting plates 4, so that the partition wing plate 5 is perpendicular to the side connecting plates 4. After folding, the main partition plate 3, the side connecting plates 4, and the partition wing plate 5 form a three-dimensional partition frame. The positioning tongue 2 extends vertically downward from the short edge of the main partition plate 3, maintaining a natural extended state, thus completing the assembly of the barrier device.

[0034] The one-piece molding structure is completed in one go through die-cutting and creasing processes, which greatly improves production efficiency, reduces assembly steps and the number of parts. The initial flat state can be folded into a very small volume through preset creases, which facilitates warehousing and transportation.

[0035] like Figure 3-4 As shown, this utility model also provides a packaging box 6, in which a packaging box blocking device as described above is provided. Insert holes 7 are provided on both side walls of the packaging box 6, and the positioning tongue 2 of the packaging box blocking device is inserted into the insert hole 7.

[0036] The packaging box 6 integrates the aforementioned divider device within itself, precisely engaging with the insertion holes 7 on the box wall to form a robust internal partition system. This packaging box 6 effectively isolates and independently controls multiple items within, significantly reducing the risk of damage from shaking or squeezing. The stable internal compartments ensure products remain neatly arranged upon opening, enhancing the product's perceived quality and user experience. Simultaneously, reliable protection reduces after-sales disputes, adding value to the product.

[0037] In one embodiment, such as Figure 3 As shown, the insertion holes 7 are respectively opened on two opposite inner sidewalls of the packaging box 6, and the insertion holes 7 on the two inner sidewalls are symmetrically distributed; The insertion hole 7 is a horizontal insertion hole 7, and the positioning tongue 2 extends vertically downward from the short edge of the main body partition plate 3 and is inserted into the horizontal insertion hole 7.

[0038] Using the above scheme, the symmetrically distributed transverse insertion holes 7 cooperate with the downwardly extending positioning tongue 2. This structure can effectively resist impacts and vibrations from the front, back, left, and right directions, and the fixing effect is far superior to the unidirectional insertion structure.

[0039] In one embodiment, the packaging box 6 further includes a lid. By providing the lid, together with the box body equipped with a divider, a complete closed package is formed, providing all-round protection for the contents and meeting the packaging needs of most commodities.

[0040] Preferably, the lid is configured in any of the following structural forms: 1) A lid with a snap-fit ​​design, the shape of which is adapted to the shape of the top opening of the packaging box 6, and can be directly snapped onto the top opening of the packaging box 6. 2) Pull-out lid, which is slidably connected to the outer side wall of the packaging box 6 and can be pulled out laterally to cover or open the top opening of the packaging box 6.

[0041] Although this document frequently uses terms such as positioning tongue, main body partition plate, two side connecting plates, and partition wing plate, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
