Description

Technical Field

[0001] This utility model relates to the field of cardboard boxes, and in particular to an integrated display box. Background Technology

[0002] Cardboard packaging, as a common form of packaging, is widely used in daily chemicals, food, electronic products, cosmetics, tobacco and alcohol, and other products. Through creative graphic and structural designs, cardboard packaging can stand out on the shelf and attract consumers' attention.

[0003] However, existing folded cardboard boxes are easily deformed by stress when moved along with their contents, which can lead to them falling apart and making them unreliable. Utility Model Content

[0004] The purpose of this invention is to provide a robust and durable integrated display case to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A robust and durable one-piece display case, including the case body;

[0007] The front, rear, left, and right side walls of the box are all hollow structures;

[0008] The sidewall includes an inner side plate, an upper plate, and an outer side plate. The inner side plates of the rear, left, and right sidewalls are all provided with hollowed-out portions, and the lower edge of the hollowed-out portions is connected to a support plate that reinforces the sidewall.

[0009] The upper edge of the support plate is connected to a first folded edge that reinforces the side wall;

[0010] After the box body is folded and formed, the support plate is folded to the outer side of the outer plate to form a reinforcing structure that is engaged between the inner and outer side plates of the side wall.

[0011] By adopting the above technical solution, the upper part of the support plate has been pre-treated during the cutting of the cardboard and separated from the inner side plate of the side wall. The lower end of the support plate is integrally formed with the inner side plate of the side wall. By bending the support plate towards the outer side plate, the support plate forms a support bridge between the inner and outer side plates, making the originally fragile hollow structure more stable. If there is only one support plate, it is easy for the support plate to slide on the inner side wall of the outer side plate when it encounters impact or vibration, resulting in structural instability. With the setting of the first folded edge, which is located at the end of the support plate near the outer side plate, it can be folded to form a reinforced folded edge that contacts the inner side wall of the outer side plate. This provides friction and makes the original support bridge more stable. The resulting three-dimensional support reinforcement structure significantly improves the compressive strength and overall stability of the box side wall, effectively preventing the box from deforming or cracking during transportation.

[0012] In a further embodiment, a mounting hole is provided at the lower end of one side of the side wall of the housing;

[0013] A magnetic fixing device can be detachably installed in the mounting hole;

[0014] The magnetic fixing device includes a limiting block, a connecting rod, and a magnetic block;

[0015] The connecting rod passes through the mounting hole, and the diameter of the mounting hole is larger than the diameter of the connecting rod;

[0016] One outer end of the connecting rod is connected to a limit block, and one inner end of the connecting rod is detachably connected to a magnetic block.

[0017] The length and width of the limiting block are both greater than the diameter of the mounting hole;

[0018] The length and width of the magnetic block are both smaller than the width of the hollow sidewall structure.

[0019] By adopting the above technical solution, the magnetic fixing device can easily fix the box to the shelf or other positions. The side wall of the box has a hollow structure, while the bottom of the box is very thin, with only one bottom plate, making it difficult to install the magnetic device. Therefore, taking advantage of the hollow structure of the side wall, the device is installed inside the side wall. During installation, the side wall is bent upwards from the end away from the bottom plate to the edge of the bottom plate. In this process, the magnetic block is first placed in the side wall, and then the connecting rod with the limit block is inserted through the mounting hole. The connecting rod is attracted to the magnetic block, and the magnetic device is now installed. When the box is placed on the shelf, the magnetic device can firmly attract it to the shelf. When it needs to be removed, since the diameter of the mounting hole is larger than the diameter of the connecting rod, the limit block can be grasped and the connecting rod lifted upwards. At this time, the magnetic block leaves the shelf, and the box can be removed normally. The magnetic device can be reused multiple times and is also low in cost.

[0020] In a further embodiment, a cardboard box folded into a box body is also included;

[0021] The cardboard includes a base plate, side plates located on both sides of the base plate, a rear plate located behind the base plate, and a front plate located in front of the base plate.

[0022] The rear plate is provided with rear insert tongues on both the left and right sides;

[0023] Each of the side plates located on both sides of the base plate has a front insert tongue.

[0024] The front end of the side plate has a front limiting groove, and the rear end of the side plate has a rear limiting groove.

[0025] After the cardboard is folded, the end of the front tongue that is away from the side plate is inserted into the front limiting groove;

[0026] The end of the rear tongue that is away from the rear plate is inserted into the rear limiting groove.

[0027] By adopting the above technical solution, the entire cardboard includes a main base plate, as well as side plates, rear plates and front plates extending around the base plate. The fixing of these plates to each other mainly relies on tongues and limiting grooves. By inserting the front tongue of the side plate into the corresponding front limiting groove and inserting the rear tongue of the side plate into the rear limiting groove, the side plate can be initially fixed, and the entire box can be fixed by subsequent folding.

[0028] In a further embodiment, the side panel folds to form the left and right side walls of the box.

[0029] The outer side plates are located on the left and right sides of the bottom plate, respectively. The side of the outer side plate away from the bottom plate is connected to the upper plate, and the side of the upper plate away from the outer side plate is connected to the inner side plate.

[0030] By adopting the above technical solution, since the folding is done from the left and right sides of the base plate towards the base plate, the side plate is the outermost part closest to the base plate, the next closest part is the upper part, and the part furthest from the base plate is the innermost part. The previously mentioned hollowed-out part is also located on the innermost side plate after folding. The reinforcing structure at the hollowed-out part can improve the strength of the entire inverted U-shaped structure and increase its stability.

[0031] In a further embodiment, a left hook-shaped plate is provided on the rear side of the outer side plate on the left side of the base plate, and a right hook-shaped plate that cooperates with the left hook-shaped plate is provided on the rear side of the outer side plate on the right side of the base plate.

[0032] By adopting the above technical solution, the hooks of the hook-shaped plate face the same direction when folded. After folding, the two hooks can be locked together, which is beneficial to the fixation of the left and right cavities and can further improve its stability.

[0033] In a further embodiment, the inner side plates on both the left and right sides of the base plate are provided with a second folded edge for reinforcing the side wall on the side away from the base plate.

[0034] By adopting the above technical solution, the second folded edge mainly contacts the top of the bottom plate, which can effectively enhance the strength of the left and right inner sides and further improve the structural strength of the entire box.

[0035] In a further embodiment, the front and rear sides of the inner side plate are both provided with reinforcing plates that are connected to the side walls.

[0036] By adopting the above technical solution, after the folding is completed, the reinforcing plates on the front and rear sides of the inner side panel can firmly support and reinforce the bottom front and rear sides of the side wall, enhancing the strength of the hollow structure from multiple directions and ensuring stability during movement.

[0037] In summary, this utility model has the following beneficial effects:

[0038] 1. Through the setting of the tongue and the limiting groove, the cooperation between the front tongue and the front limiting groove and the rear tongue and the rear limiting groove forms a mechanical interlocking structure. When the cardboard is folded and formed, the side wall is automatically and accurately aligned and fixed. This design not only simplifies the assembly process, eliminating the need for glue or additional tools, but also effectively disperses the force on the box through multi-point engagement. When the box is squeezed or vibrated, the engagement of the tongue and the limiting groove can prevent the side wall from being misaligned and deformed. Especially for the display box, which often needs to be moved frequently, it significantly reduces the risk of the box falling apart during transportation. At the same time, the support plate connected to the hollow part and the three-dimensional support structure formed by the first folded edge further strengthen the compressive strength of the hollow side wall, so that the box can still maintain its three-dimensional shape under load, achieving the effect of quick assembly and stable fixation of the box.

[0039] 2. By using hook-shaped panels, the left and right hook-shaped panels interlock after the box is formed, transforming the originally independent hollow left and right side walls into a unified load-bearing unit. This design creates a horizontally stable frame. When one side is impacted, the interlocking mechanism of the hook-shaped panels transfers stress to the opposite side, preventing local deformation from amplifying. Combined with the vertical reinforcement of the support plates, this forms a crisscrossing three-dimensional reinforcement network, enabling the box to resist multi-directional external forces when stacked on shelves or during handling. Furthermore, the integrated design of the hook-shaped panels eliminates the need for additional connectors, maintaining the environmentally friendly characteristics of the cardboard box while improving assembly efficiency.

[0040] 3. By setting the second fold and reinforcing plate, the contact area between the second fold and the top of the bottom plate is increased, forming a reinforcement effect similar to the ground beam of a building. This effectively prevents the bottom of the box from collapsing due to the load. The reinforcing plates on the front and rear sides of the inner side plate extend longitudinally to the front and rear edges of the box, forming an I-shaped support system together with the support plate. This significantly improves the bending resistance of the side wall. This multi-layered reinforcement design allows the hollow structure to maintain its lightweight while having a compressive strength close to that of solid cardboard. It is especially suitable for scenarios that require displaying goods and frequent handling. Each reinforcement component is achieved by bending the cardboard itself, achieving a balance between cost and performance. Attached Figure Description

Detailed Implementation

[0045] The present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the attached figures. Figure 1 In this specification, the terms "bottom surface" and "top surface," "inner" and "outer" refer to the direction toward or away from the geometry of a specific component. 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 one or more of that feature. In the description of this specification, "a plurality of" means two or more, unless otherwise explicitly and specifically defined by the direction of the center.

[0047] The robust and durable one-piece display case includes a case body 1. The front, rear, left, and right side walls 2 of the case body 1 are all hollow structures. The side walls 2 include an inner side panel 21, an upper panel 22, and an outer side panel 23. The inner side panels 21 of the rear, left, and right side walls 2 are all provided with hollow parts. The lower edge of the hollow part is connected to a support plate 3 for reinforcing the side wall 2. The upper edge of the support plate 3 is connected to a first folded edge 4 for reinforcing the side wall 2. After the case body 1 is folded and formed, the support plate 3 is folded towards the outer side panel 23 to form a reinforcing structure that is engaged between the inner side panel 21 and the outer side panel 23 of the side wall.

[0048] By adopting the above technical solution, the upper part of the support plate 3 has been pre-treated when cutting the cardboard 5 and is separated from the inner side plate 21 of the side wall 2. The lower end of the support plate 3 is integrally formed with the inner side plate 21 of the side wall 2. By bending the support plate 3 towards the outer side plate 23, the support plate 3 will form a support bridge between the inner side plate 21 and the outer side plate 23, making the originally fragile hollow structure more stable. If there is only one support plate 3, the support plate 3 is prone to sliding on the inner side wall 2 of the outer side plate 23 when it encounters impact or vibration, which will lead to structural instability. With the setting of the first folded edge 4, the first folded edge 4 is at the end of the support plate 3 near the outer side plate 23. It can be folded to form a reinforced folded edge that contacts the inner side wall 2 of the outer side plate 23. While providing friction, it also makes the original support bridge more stable. The resulting three-dimensional support reinforcement structure significantly improves the compressive strength and overall stability of the side wall 2 of the box 1, effectively preventing the box 1 from deforming or cracking during transportation.

[0049] In a further embodiment, a mounting hole is provided at the lower end of one side of the side wall 2 of the housing 1. A magnetic fixing device is detachably installed in the mounting hole. The magnetic fixing device includes a limiting block, a connecting rod, and a magnetic block. The connecting rod passes through the mounting hole, the diameter of which is larger than the diameter of the connecting rod. The outer end of the connecting rod is connected to the limiting block, and the inner section of the connecting rod is detachably connected to the magnetic block. The length and width of the limiting block are both larger than the diameter of the mounting hole, and the length and width of the magnetic block are both smaller than the width of the hollow structure of the side wall 2.

[0050] By adopting the above technical solution, the magnetic fixing device can easily fix the box 1 to the shelf or other positions. The side wall 2 of the box 1 has a hollow structure, and the bottom of the box 1 is very thin, with only one bottom plate 51, so it is not easy to install the magnetic device. Therefore, by taking advantage of the hollow structure of the side wall 2, it is installed inside the side wall 2. During the installation process, the side wall 2 is bent upward from the end away from the bottom plate 51 to the edge of the bottom plate 51. In this process, the magnetic block is first placed in the side wall 2, and then the connecting rod with the limit block is inserted into the mounting hole. The connecting rod is attracted to the magnetic block. At this time, the magnetic device is installed. When the box 1 is placed on the shelf, the magnetic device can firmly attract it to the shelf. When it needs to be removed, since the diameter of the mounting hole is larger than the diameter of the connecting rod, the limit block can be grasped and the connecting rod can be lifted upward. At this time, the magnetic block leaves the shelf, and the box 1 can be removed normally. Moreover, the magnetic device can be reused multiple times and has the characteristics of low cost.

[0051] In a further embodiment, a cardboard 5 folded into a box body 1 is also included. The cardboard 5 includes a bottom plate 51, side plates 52 located on both sides of the bottom plate 51, a rear plate 53 located behind the bottom plate 51, and a front plate 54 located in front of the bottom plate 51. Rear tongues 6 are provided on the left and right sides of the rear plate 53, and front tongues 7 are provided on the front sides of the side plates 52 located on both sides of the bottom plate 51. A front limiting groove is opened at the front end of the side plate 52, and a rear limiting groove is opened at the rear end of the side plate 52. After the cardboard 5 is folded, the end of the front tongue 7 away from the side plate 52 is inserted into the front limiting groove, and the end of the rear tongue 6 away from the rear plate 53 is inserted into the rear limiting groove.

[0052] By adopting the above technical solution, the entire cardboard 5 includes a main base plate 51, and side plates 52, rear plates 53 and front plates 54 extending around the base plate 51. The fixing of these plates to each other mainly relies on tongues and limiting grooves. By inserting the front tongue 7 of the side plate 52 into the corresponding front limiting groove and inserting the rear tongue 6 of the side plate 52 into the rear limiting groove, the side plate 52 can be initially fixed, and the entire box 1 can be fixed by subsequent folding.

[0053] In a further embodiment, the side panel 52 is folded to form the left side wall 2 and right side wall 2 of the box 1. The outer side panel 23 is located on the left and right sides of the bottom plate 51 respectively. The side of the outer side panel 23 away from the bottom plate 51 is connected to the upper plate 22, and the side of the upper plate 22 away from the outer side panel 23 is connected to the inner side panel 21.

[0054] By adopting the above technical solution, since the folding is performed from the left and right sides of the base plate 51 towards the base plate 51, the three parts of the side plate are such that the part closest to the base plate 51 is on the outermost side, the part next closest to the base plate 51 is on the upper part, and the part furthest from the base plate 51 is on the innermost side. The previously mentioned hollowed-out part is also located on the innermost side plate 21 after folding. The reinforcing structure of the hollowed-out part can improve the strength of the entire inverted U-shaped structure and increase its stability.

[0055] In a further embodiment, a left hook-shaped plate 8 is provided on the rear side of the outer side plate 23 on the left side of the base plate 51, and a right hook-shaped plate 9 that cooperates with the left hook-shaped plate 8 is provided on the rear side of the outer side plate 23 on the right side of the base plate 51.

[0056] By adopting the above technical solution, the hooks of the hook-shaped plate face the same direction when folded. After folding, the two hooks can be locked together, which is beneficial to the fixation of the left and right cavities and can further improve its stability.

[0057] In a further embodiment, the inner side plates 21 on the left and right sides of the base plate 51 are provided with a second folded edge 10 for reinforcing the side wall 2 on the side away from the base plate 51.

[0058] By adopting the above technical solution, the second folded edge 10 mainly contacts the top of the bottom plate 51, which can effectively enhance the strength of the left and right inner sides and further improve the structural strength of the entire box 1.

[0059] In a further embodiment, the front and rear sides of the inner side plate 21 are provided with reinforcing plates 11 that are connected to the reinforcing sidewalls 2.

[0060] By adopting the above technical solution, after the folding is completed, the reinforcing plates 11 on the front and rear sides of the inner side plate 21 can firmly support and reinforce the bottom front and rear sides of the side wall 2, thereby enhancing the strength of the hollow structure from multiple directions and ensuring stability during movement.
