Description

Technical Field

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

[0002] A display case is a type of packaging box that also serves a display function. Existing product display cases are one-piece folding structures. Due to connection considerations, there are redundant connection structures in the various connecting parts of the cardboard, resulting in the unfolded area of ​​most cases being greater than 2 square meters. This large unfolded area brings many problems: First, the structure is complex, making it difficult to process, store, and transport; second, the folding process is cumbersome, time-consuming, labor-intensive, and inconvenient to operate.

[0003] Using a modular display case can overcome the difficulties in processing, storage, and transportation caused by a large unfolded area, and also solves the problem of inconvenient folding. However, it has the problem that its protective strength is not as strong as that of an integrated folding structure. Therefore, it is necessary to improve the modular display case to make it easy to use, save cardboard materials, and provide a certain level of protection. Utility Model Content

[0004] The purpose of this invention is to provide a modular display case that is easy to fix, in order 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 modular display case that is easy to secure, comprising an inner box and an outer box that covers the outside of the inner box;

[0007] The inner box is provided with a first folded edge to reinforce the box at multiple edges;

[0008] An insertion hole is provided on the first folded edge;

[0009] The outer casing has a second folded edge corresponding to the position of the first folded edge on multiple edges. The side of the second folded edge away from the outer casing has a tongue that mates with the corresponding socket.

[0010] The rear side of the outer casing is provided with at least two interlocking hook-shaped plates.

[0011] By adopting the above technical solution, due to the split structure, the outer and inner panels that make up the outer and inner boxes can be folded and stored separately, significantly reducing the unfolded area of ​​a single package. This makes processing, warehousing, and transportation more efficient, especially suitable for mass production and logistics distribution. Traditional integrated display boxes have a cumbersome folding process, but this utility model, through its covering structure and the snap-fit ​​fixing method of the tongue and the hole, allows the inner and outer boxes to be quickly assembled without complicated folding steps, significantly improving efficiency. It is suitable for scenarios such as exhibitions and retail that require frequent disassembly and assembly. Split structures usually have weaker protection, but this utility model, through the insertion hole on the second fold edge of the outer panel and the first fold edge of the inner panel... The tightly interlocking holes on the sides form a stable double-layer structure, ensuring the inner box is securely fixed to the top of the outer box. This effectively reduces shaking during transportation or display, enhancing the protection of exhibits. The exhibition compartment formed by the inner box allows for a direct view of the exhibits, while the outer box's covering design not only strengthens protection but also maintains a clean appearance. It is suitable for the high-end display needs of branded goods, combining functionality and visual appeal. In summary, this utility model, through innovative split-type splicing and interlocking fixing technology, simplifies operation and saves costs while ensuring protection and stability, providing an efficient and economical solution for product display and transportation, with broad market application prospects.

[0012] In a further embodiment, the upper end of the inner sidewall of the inner box is provided with an openable opening, which serves as a fixing hole for fixing all the displayed products.

[0013] The fixing holes have openable cardboard as a buffer plate;

[0014] The buffer plate has three disconnectable sides on the cardboard box: top, left, and right, as well as a connection point at the bottom.

[0015] The top, left, and right three disconnectable edges have at least half their length as cut-off structures, and the remaining part is a pre-cut structure;

[0016] The buffer plate is provided with creases in the left and right directions;

[0017] An adhesive layer is provided on the top of the buffer plate;

[0018] The buffer plate is bent along the crease and then bonded to other parts of the inner box through an adhesive layer to form a support structure.

[0019] By adopting the above technical solution, the cushioning board can also change its shape and bending angle according to the size and shape of the exhibits, thereby improving the adaptability of the box. The cushioning board, through the design of the pre-break point structure and the detachable edge, not only ensures the integrity of the initial state, but also allows the opening to be quickly opened when needed, so that the cushioning board can be separated and bent into shape. The combination of creases and self-adhesive layer makes the cushioning board firmly form a support structure, effectively absorbing the vibration energy during transportation, and limiting the exhibits to a certain extent, reducing the risk of exhibits being damaged by collisions. This design does not require additional accessories and can achieve the cushioning function solely through the structure of the cardboard itself.

[0020] In a further embodiment, the outer casing includes an outer panel that folds into the outer casing;

[0021] The outer plate includes a rectangular base plate and an outer side plate connected to the edge of the base plate;

[0022] The outer side plates located on the front and rear sides of the base plate have the same width, and the length of the outer side plate located on the front side of the base plate is less than the length of the outer side plate located on the rear side of the base plate.

[0023] After folding, the multiple outer panels surround each other to form a storage compartment for the inner box.

[0024] By adopting the above technical solution, the outer panel, with its differentiated length side panel design, naturally forms a storage compartment structure that is open on the front and enclosed on the rear after folding. This facilitates the loading and unloading of the inner box while retaining the protective function of the outer box for the rear and sides. The integrated design of the rectangular bottom plate and side panels reduces splicing gaps and enhances the overall structural strength. At the same time, the standardized cutting process reduces material waste, achieving an optimal balance between production costs and protective performance.

[0025] In a further embodiment, the inner box includes an inner panel that folds into the inner box.

[0026] The inner plate includes a middle plate and inner side plates respectively disposed on the left and right sides of the middle plate;

[0027] The inner box is open at both the top and bottom;

[0028] The middle plate of the inner panel becomes the back plate of the inner box after being folded over;

[0029] After folding, the multiple first folded edges become the horizontal support structure between the inner and outer boxes.

[0030] By adopting the above technical solution, the inner panel forms a double-open frame structure through the folding of the middle panel and the inner side panel, which makes it easy to put and take off exhibits from above or in front. The first folded edge transforms into a horizontal support structure after being assembled, forming multiple stress points with the second folded edge of the outer box, effectively dispersing external pressure and avoiding single-point deformation. At the same time, the open design reduces material consumption and conforms to the concept of environmental protection and economy.

[0031] In a further embodiment, a latch for temporary fixation is provided below the first fold on the side of the inner side plate away from the middle plate;

[0032] After folding, the lower end of the latch is engaged and fixed with the upper end of the outer side panel on the front side of the outer casing.

[0033] By adopting the above technical solution, the snap-fit ​​between the latch and the outer box side panel realizes the pre-fixation of the inner box, prevents displacement during the assembly process, ensures the precise alignment of the latch and the socket, simplifies the operation steps, and provides an auxiliary locking function during transportation to avoid accidental separation of the box due to vibration, thereby improving the reliability of use.

[0034] In a further embodiment, the second folded edge is provided with an arc-shaped structure that facilitates the fixing of the box body.

[0035] By adopting the above technical solution, the arc-shaped structure plays a guiding role during insertion, reducing the difficulty of connecting the tongue and the hole. At the same time, the arc surface can reduce the friction loss of the cardboard, extend the number of times it can be reused, and form a slight elastic deformation after splicing, which enhances the tightness of the insertion part and further suppresses the shaking of the box.

[0036] In a further embodiment, a magnet device is provided at the bottom of the outer casing, and the magnet device is a magnet device with a Haier shell structure;

[0037] The bottom of the outer box has an assembly hole for holding a magnet device. A plastic sheet is provided on the outside of the assembly hole. The plastic sheet is embedded into the bottom of the carton and glued in place.

[0038] A detachable iron plate is suspended on the outer casing;

[0039] The area of ​​the iron sheet is larger than the lower surface of the magnet device.

[0040] By adopting the above technical solutions, the magnetic device of Haier's shell structure is firmly embedded in the bottom of the box through a plastic sheet to avoid the risk of falling off. The combination of the detachable iron sheet and the magnet allows the display box to be flexibly attached to metal display racks or counters, adapting to various scene layout needs. The large area design of the iron sheet ensures the stability of the attachment, and the box can be stacked or stored normally after disassembly, achieving a balance between functional expansion and space efficiency.

[0041] In a further embodiment, the bottom end of the inner box is provided with a grid structure for reinforcing the box;

[0042] The grid structure is symmetrically arranged on both sides of the inner box, away from the outer box.

[0043] By adopting the above technical solution, the grid structure forms a triangular support frame through symmetrical distribution, which significantly improves the compressive strength of the bottom of the inner box and prevents the weight of the exhibits from being concentrated and deformed. At the same time, the hollow design reduces the overall weight, taking into account both load-bearing requirements and material conservation. It is especially suitable for exhibits with high bottom protection requirements, such as expensive cosmetics or electronic products.

[0044] In summary, this utility model has the following beneficial effects:

[0045] 1. By combining inner and outer casings, both protection and display functions can be achieved simultaneously. The inner casing precisely connects to the outer casing's tongue via a first folded edge with interlocking holes, forming a stable double-layer protective structure. This design reduces the unfolded area of ​​a single casing, significantly decreasing storage and transportation space compared to traditional integrated display cases. In practical applications, staff simply place the pre-folded inner casing into the outer casing and assemble it by simply inserting the tongue and interlocking holes. The entire process takes no more than 30 seconds, significantly improving setup efficiency. Simultaneously, the staggered overlap of the first and second folded edges forms a multi-point stress structure, effectively resisting external impacts during transportation. This design retains the advantages of a modular structure for easy transport while overcoming the shortcomings of traditional modular cases in terms of protection through innovative interlocking methods, simplifying the assembly process and reducing storage and transportation costs.

[0046] 2. The pre-cut structure and adjustable support design of the buffer plate enable stable fixation without additional accessories. The buffer plate features a three-sided pre-cut design, with 50% of the length pre-cut on the top, left, and right sides, leaving a slightly connected pre-cut structure on the remaining portion. This ensures the integrity of the initial state while allowing for flexible adjustment of the opening size according to the exhibit size. The pre-cut points can be easily torn open, and the buffer plate can be bent at the desired angle along the pre-set creases, then fixed using the pre-coated adhesive layer to form a personalized display stand. This design is suitable for various exhibits with heights between 5 and 15 cm. Especially for fragile items, the three-sided protective structure formed by the buffer plate effectively prevents the exhibit from shifting. The entire adjustment process requires no tools, truly achieving "tear and use," significantly reducing the time cost of exhibit setup. It adapts to different exhibit sizes, provides elastic cushioning protection, and achieves stable fixation without additional accessories.

[0047] 3. By incorporating a magnet device, a Heilbeck magnet array structure can be used at the bottom of the cabinet. The embedded plastic sheet ensures uniform magnetic force distribution and prevents the magnet from easily falling off. The matching detachable iron sheet design allows the cabinet to be firmly attached to a metal display stand for stable display, while also facilitating quick disassembly and repositioning. A single magnet module can provide sufficient adsorption force, fully meeting conventional display needs. This expands the applicability of display scenarios, enhances the load-bearing capacity of the bottom, and satisfies the dual requirements of stability and protection for high-end products.

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 1In 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.

[0058] Example 1:

[0059] like Figure 1 - Figure 6 As shown, the easily fixed split display case includes an inner box 1 and an outer box 2 covering the outside of the inner box 1. The inner box 1 has a first folded edge 3 for reinforcing the box at multiple edges, and the first folded edge 3 is provided with an insertion hole. The outer box 2 has a second folded edge 5 at multiple edges corresponding to the position of the first folded edge 3. The side of the second folded edge 5 away from the outer box 2 is provided with a tongue 4 that cooperates with the corresponding insertion hole. The rear side of the outer box 2 is provided with at least two interlocking hook plates 6.

[0060] By adopting the above technical solution, due to the use of a split structure, the outer panel 7 and inner panel 8 that make up the outer box 2 and inner box 1 can be folded and stored separately, greatly reducing the unfolded area of ​​a single package. This makes processing, warehousing, and transportation more efficient, especially suitable for mass production and logistics distribution. Traditional integrated display boxes have a cumbersome folding process, but this utility model, through its covering structure and the snap-fit ​​fixing method of the tongue 4 and the insertion hole, allows the inner box 1 and outer box 2 to be quickly assembled without complicated folding steps, significantly improving efficiency. It is suitable for scenarios such as exhibitions and retail that require frequent disassembly and assembly. Split structures usually have weaker protection, but this utility model, through the insertion hole of the second folded edge 5 of the outer panel 7 and the inner panel 8, The first folded edge 3 is tightly inserted into the socket, forming a stable double-layer structure. This ensures that the inner box 1 is firmly fixed to the inner top of the outer box 2, effectively reducing shaking during transportation or display and improving the protection of exhibits. The exhibition compartment formed by the inner box 1 allows for a direct view of the exhibits. The covering design of the outer box 2 not only enhances protection but also maintains a clean appearance. It is suitable for the high-end display needs of branded goods, combining functionality and visual appeal. In summary, this utility model, through innovative split splicing and plug-in fixing technology, simplifies operation and saves costs while taking into account protection and stability. It provides an efficient and economical solution for product display and transportation, and has broad market application prospects.

[0061] In a further embodiment, the upper end of the inner sidewall of the inner box 1 is provided with an openable opening as a fixing hole for fixing all the displayed products. The fixing hole has an openable cardboard as a buffer plate. The buffer plate has three detachable sides on the cardboard box, namely the top, left and right sides, and a connection point at the bottom. The three detachable sides have a cut-off structure for at least half of their length, and the remaining part is a pre-cut-off structure. The buffer plate is provided with creases in the left and right directions. An adhesive layer is provided on the top of the buffer plate. After the buffer plate is bent along the creases, it is bonded to other parts of the inner box 1 that it contacts through the adhesive layer to form a support structure.

[0062] By adopting the above technical solution, the cushioning board can also change its shape and bending angle according to the size and shape of the exhibits, thereby improving the adaptability of the box. The cushioning board, through the design of the pre-break point structure and the detachable edge, not only ensures the integrity of the initial state, but also allows the opening to be quickly opened when needed, so that the cushioning board can be separated and bent into shape. The combination of creases and self-adhesive layer makes the cushioning board firmly form a support structure, effectively absorbing the vibration energy during transportation, and limiting the exhibits to a certain extent, reducing the risk of exhibits being damaged by collisions. This design does not require additional accessories and can achieve the cushioning function solely through the structure of the cardboard itself.

[0063] In a further embodiment, the outer box 2 includes an outer panel 7 that folds into the outer box 2. The outer panel 7 includes a rectangular bottom plate 71 and outer side plates 72 connected to the edge of the bottom plate 71. The width of the outer side plates 72 located on the front and rear sides of the bottom plate 71 is the same. The length of the outer side plate 72 located on the front side of the bottom plate 71 is less than the length of the outer side plate 72 located on the rear side of the bottom plate 71. After folding, the multiple outer side plates 72 surround each other to form a storage compartment for placing the inner box 1.

[0064] By adopting the above technical solution, the outer panel 7, with its differentiated length side panel design, naturally forms a storage compartment structure with an open front and enclosed rear after folding. This facilitates the loading and unloading of the inner box 1 while retaining the protective function of the outer box 2 for the rear and sides. The integrated design of the rectangular base plate 71 and the side panels reduces splicing gaps and enhances the overall structural strength. At the same time, the standardized cutting process reduces material waste and achieves an optimized balance between production cost and protective performance.

[0065] In a further embodiment, the inner box 1 includes an inner panel 8 that folds into the inner box 1. The inner panel 8 includes a middle panel 81 and inner side panels 82 respectively disposed on the left and right sides of the middle panel 81. The upper and lower parts of the inner box 1 are open. After folding, the middle panel 81 of the inner panel 8 becomes the back panel of the inner box 1. After folding, multiple first folded edges 3 become the horizontal support structure between the inner box 1 and the outer box 2.

[0066] By adopting the above technical solution, the inner panel 8 forms a double-sided open frame structure through the folding of the middle panel 81 and the inner side panel 82, which makes it easy to take the exhibits from the top or the front. The first folded edge 3 is transformed into a horizontal support structure after being assembled, forming multiple stress points with the second folded edge 5 of the outer box 2, effectively dispersing external pressure and avoiding single-point deformation. At the same time, the open design reduces material consumption and conforms to the concept of environmental protection and economy.

[0067] In a further embodiment, a latch 9 for temporary fixation is provided below the first folded edge 3 on the side of the inner side plate 82 away from the middle plate 81. After folding, the lower end of the latch 9 is engaged and fixed with the upper end of the outer side plate 72 on the front side of the outer box 2.

[0068] By adopting the above technical solution, the snap-fit ​​between the latch 9 and the side plate of the outer casing 2 achieves the pre-fixation of the inner casing 1, preventing displacement during the assembly process, ensuring the precise alignment of the latch 4 and the socket, simplifying the operation steps, and providing an auxiliary locking function during transportation to avoid accidental separation of the casing due to vibration, thereby improving the reliability of use.

[0069] In a further embodiment, the second folded edge 5 is provided with an arc-shaped structure that facilitates the fixing of the box body.

[0070] By adopting the above technical solution, the arc-shaped structure plays a guiding role during insertion, reducing the difficulty of connecting the tongue 4 and the insertion hole. At the same time, the arc surface can reduce the friction loss of the cardboard, extend the number of reuses, and form a slight elastic deformation after splicing, which enhances the tightness of the insertion part and further suppresses the shaking of the box.

[0071] In a further embodiment, a magnet device is provided at the bottom of the outer box 2. The magnet device adopts the Haier shell structure. The bottom of the outer box 2 has an assembly hole for holding the magnet device. A plastic sheet is provided on the outside of the assembly hole. The plastic sheet is embedded into the bottom of the carton and glued and fixed. A detachable iron sheet is suspended on the outer box 2. The area of ​​the iron sheet is larger than the lower surface of the magnet device.

[0072] By adopting the above technical solutions, the magnetic device of Haier's shell structure is firmly embedded in the bottom of the box through a plastic sheet to avoid the risk of falling off. The combination of the detachable iron sheet and the magnet allows the display box to be flexibly attached to metal display racks or counters, adapting to various scene layout needs. The large area design of the iron sheet ensures the stability of the attachment, and the box can be stacked or stored normally after disassembly, achieving a balance between functional expansion and space efficiency.

[0073] Example 2:

[0074] like Figure 1 - Figure 7As shown, the easy-to-fix split display case has a grid structure 10 for reinforcing the case at the bottom of the inner box 1. The grid structure 10 is symmetrically arranged on both sides of the inner box 1 away from the outer box 2.

[0075] By adopting the above technical solutions, in addition to the more conventional inner box 1 style in Embodiment 1, while keeping the structure and fixing method of the outer box 2 unchanged, a grid structure 10 with symmetrically distributed support frames on the bottom and triangular support frames on both inner side walls can also be used. This structure significantly improves the compressive strength of the bottom of the inner box 1, prevents the weight of the exhibit from being concentrated and causing deformation, and at the same time, the hollow design reduces the overall weight, taking into account both load-bearing requirements and material saving. It is especially suitable for exhibits with high bottom protection requirements, such as expensive cosmetics or electronic products.

[0076] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0077] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
