Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carton, in particular to a stacked honeycomb carton. BACKGROUND

[0002] In the field of heavy logistics transportation, the packaging box needs to meet the three core demands of bearing capacity, transportation economy and environmental protection. Traditional heavy logistics packaging mainly relies on two types of products, wooden boxes and ordinary honeycomb cartons, but both have significant technical defects:

[0003] On the one hand, although wooden boxes can match the bearing requirements of heavy goods, their own weight is large, resulting in high transportation energy consumption, and the wooden boxes cannot be folded, so they occupy a large space when returning or storing, greatly increasing the cost of empty box transportation and storage, and the recycling rate of wooden boxes is low, which does not meet the development trend of green logistics; on the other hand, although traditional honeycomb cartons have the characteristics of lightweight and recyclability, they are limited by structural design and rely only on the strength of the surrounding plate for bearing, lacking targeted bearing reinforcement structure, and when bearing the weight of heavy goods or stacking and storing, the box body is prone to collapse and deformation due to uneven local stress, which cannot meet the bearing requirements of heavy logistics.

[0004] In the prior art, some improved honeycomb cartons try to improve the bearing capacity by simple splicing structure, but often have problems such as insufficient structural stability, poor disassembly, or limited volume compression effect after disassembly. Especially in long-term cyclic use or large-height specification box application scenarios, the splicing part is prone to deformation due to lateral load conduction, resulting in a decrease in the durability and reliability of the overall structure of the box body, making it difficult to meet the multiple demands of high bearing, convenient transportation and environmental protection recycling, which has become a key bottleneck restricting the upgrading of heavy logistics packaging. SUMMARY

[0005] The purpose of the present application is to provide a stacked honeycomb carton to solve the problems raised in the background art.

[0006] To achieve the above-mentioned purpose of the application, the technical scheme adopted by the present application is as follows:

[0007] The stacked honeycomb carton provided by the present application comprises an upper cover, a surrounding plate system and a base, the surrounding plate system comprises two symmetrically arranged supporting honeycomb plates and two symmetrically arranged splicing honeycomb plates, the supporting honeycomb plates are each provided with a splicing groove at both inner side edges in the height direction, the splicing groove is formed by an outer paper corner, a honeycomb reinforcing rib and the supporting honeycomb plate;

[0008] The outer paper corner protector comprises a first adhering sheet body adhered and fixed to the outer side edge of the supporting honeycomb plate along the height direction, and a second extending sheet body at a 90° angle with the first adhering sheet body and extending to the inner side of the supporting honeycomb plate; the honeycomb reinforcing rib comprises a honeycomb strip adhered and fixed to the inner side of the supporting honeycomb plate, and an inner paper corner protector adhered and fixed to two corners of the honeycomb strip away from the supporting honeycomb plate.

[0009] The insertion slot is formed between the first adhering sheet body and the inner paper corner protector close to the first adhering sheet body, and the two side edges of the insertion honeycomb plate in the height direction are respectively inserted into the corresponding insertion slots of the two supporting honeycomb plates to form the fence system.

[0010] Further, at least one reinforcing triangular member is arranged in the insertion slot along the height direction of the supporting honeycomb plate, and the cross section of the reinforcing triangular member is a right triangle, and the side edge of the insertion honeycomb plate is provided with a matching cutout corresponding to each reinforcing triangular member;

[0011] The reinforcing triangular member comprises a first right-angled adhering surface adhered and fixed to the inner side of the second extending sheet body, a second right-angled adhering surface adhered and fixed to the inner side of the supporting honeycomb plate, and an oblique contact surface arranged between the first right-angled adhering surface and the second right-angled adhering surface away from the common connecting vertex; the depth of the matching cutout is not less than 90% of the thickness of the reinforcing triangular member, and the oblique contact surface is in close contact with the inner wall of the matching cutout.

[0012] Further, the inner paper corner protector close to the first adhering sheet body is defined as a reinforced inner corner protector, and the reinforcing triangular member is composed of a corrugated paper base material integrally formed on the side edge of the reinforced inner corner protector by continuous bending.

[0013] Further, the inner wall of the matching cutout is adhered with a reinforcing layer made of single corrugated or double corrugated paperboard, which is fully adhered to the inner wall of the matching cutout.

[0014] Further, in the same insertion honeycomb plate, an reinforcing strip is integrally formed between two reinforcing layers at the same height, and the reinforcing strip is located on the inner side of the insertion honeycomb plate and is fully adhered to the insertion honeycomb plate.

[0015] Further, the materials of the outer paper corner protector and the inner paper corner protector are high-strength corrugated corner protectors, and the heights of the outer paper corner protector and the inner paper corner protector are consistent with the height of the supporting honeycomb plate.

[0016] Further, the supporting honeycomb plate, the inserted honeycomb plate, the honeycomb strip, the upper cover and the base are all made of paper honeycomb plate, wherein the height of the honeycomb strip is matched with the height of the supporting honeycomb plate, and the bonding surface of the honeycomb strip and the supporting honeycomb plate is a continuous bonding structure.

[0017] Further, the lower surface of the upper cover is provided with a first concave clamping groove matched with the top of the baffle system, and the upper surface of the base is provided with a second concave clamping groove matched with the bottom of the baffle system.

[0018] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0019] 1. The composite insertion slot structure of the baffle system forms a reinforced connection node by surrounding the outer paper corner protector, the honeycomb reinforcing rib and the supporting honeycomb plate, and cooperates with the triangular support system constructed by the reinforcing triangular members, so that the insertion part of the four corners of the box body becomes a force-reinforced support node, effectively disperses the pressure brought by heavy goods, and avoids the problems of collapse and deformation of traditional honeycomb paper boxes caused by excessive force.

[0020] At the same time, the reinforcing triangular members limit the multidirectional displacement degree of freedom of the inserted honeycomb plate, suppress the micro-deformation of the insertion part, and greatly improve the structural stability and durability of the box body, which can adapt to long-term cyclic use and application scenarios of large-height-specification boxes.

[0021] 2. The upper cover, the base and the baffle system can be completely disassembled, and all paper components can be laid flat and folded, which greatly reduces the empty box volume occupancy rate, solves the pain points of traditional wooden boxes, such as large weight, high energy consumption of empty box transportation and waste of storage space. The disassembled components are convenient for centralized transportation and storage, which significantly reduces the economic cost and time cost of empty box return and storage, and improves the overall efficiency of logistics transportation.

[0022] 3. All components of the box body are made of paper materials, including the supporting honeycomb plate, the inserted honeycomb plate, the honeycomb reinforcing rib and various corner protector members, without metal or wooden auxiliary components, the recycling rate is much higher than that of traditional wooden boxes, and the waste can be naturally degraded without pollution to the environment, which fully meets the development requirements of green logistics and helps to realize the low-carbon and environmental protection transformation of the logistics industry.

[0023] 4. The firm bonding of the reinforcing triangular members, the outer paper corner protector and the supporting honeycomb plate, as well as the reinforcing design of the reinforcing layer and the reinforcing belt, effectively resist the impact of lateral load on the insertion part, avoid the deformation and peeling of the spliced part, and significantly improve the anti-deformation ability and structural integrity of the box body. At the same time, the baffle system can flexibly increase the honeycomb reinforcing rib according to the size requirement, adapt to the packaging requirements of different specifications of heavy goods, and further expand the application range of the product.

[0024] 5. The present application adopts integrated molding and modular design for the enclosure system and the reinforcing triangular member, simplifying the production and processing flow and assembly process, without the need for additional complex connecting components, reducing manufacturing costs. The box is split and assembled conveniently, without the need for professional tools, improving the use efficiency; and the maintenance cost of the all-paper structure is low, with long recycling service life, taking into account the practicability and economy of the product.

[0025] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present application. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0038] In order to better understand the present application, the technical solutions in the embodiments of the present application 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 the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0039] As shown in Figures 1-9 The present application provides a stacked honeycomb carton, which comprises an upper cover 1, a panel system 2 and a base 3. The core of the present application lies in the structural design of the panel system 2, which serves as the main support structure of the carton body and specifically comprises two symmetrically distributed supporting honeycomb plates 21 and two symmetrically distributed inserted honeycomb plates 22. Among them, the two inner side edges (referring to the side close to the interior of the carton body) of the supporting honeycomb plate 21 along the height direction are both configured with an inserted slot 23 adapted to the side edge of the inserted honeycomb plate 22. It is worth mentioning that the inserted slot 23 is not a simple groove structure, but a reinforced connection structure formed by the outer paper corner protector 231, the honeycomb reinforcing rib 232 and the supporting honeycomb plate 21 together.

[0040] Specifically, as shown in Figure 4 The outer paper corner protector 231 is composed of two parts, which includes a first fitting piece 2311 fixedly bonded to the outer side edge of the supporting honeycomb plate 21 along the height direction, and a second extending piece 2312 extending horizontally towards the inner side of the supporting honeycomb plate 21 at a 90° angle with the first fitting piece 2311. The first fitting piece 2311 can greatly enhance the bending resistance of the edge of the supporting honeycomb plate 21, while the second extending piece 2312 can form a limiting support for the inserted honeycomb plate 22.

[0041] The cellular reinforcing rib 232 comprises a cellular strip 2321 firmly bonded with the inner side of the supporting cellular board 21, and two inner paper corner guards 2322 respectively bonded and fixed at two corners of the cellular strip 2321 away from the supporting cellular board 21. The cellular strip 2321 provides basic support by virtue of the compression resistance of its cellular structure, and the inner paper corner guards 2322 further strengthen the impact resistance and support effect of the corner parts, thereby forming a precisely sized insertion slot 23 between the first laminated sheet body 2311 and the inner paper corner guard 2322 close to the first laminated sheet body 2311, providing a stable interface for the installation of the inserted cellular board 22. In use, the operator can align the two side edges of the two inserted cellular boards 22 in the height direction with the corresponding insertion slots 23 of the two supporting cellular boards 21, and quickly insert them by insertion, so that the four boards are tightly enclosed to form a complete enclosure system 2 by the bidirectional limiting action of the insertion slots 23. At this time, the enclosure system 2 preliminarily forms a stable frame with the rigid connection of the insertion parts, and then the upper cover 1 is buckled at the top end of the enclosure system 2, and the base 3 is installed at the bottom end of the enclosure system 2. The upper cover 1 and the base 3 limit and bind the enclosure system 2 in the radial direction through the matching structure (such as a clamping groove or a protrusion) of the edges, so that the enclosure system 2 is tightly limited in the pre-set space, and finally a stable integrated box is formed.

[0042] When the stackable cellular carton is transported in a stack, the clamping structure formed by the outer paper corner guard 231 and the inner paper corner guard 2322, in combination with the cushioning and compression resistance of the cellular strip 2321, makes the insertion parts at the four corners of the box become force-strengthened support nodes, which can effectively resist the pressure brought by heavy goods, improve the load-bearing capacity, and avoid the collapse and deformation problems of traditional cellular cartons caused by excessive stress. When the stackable cellular carton is transported or stored, the upper cover 1, the base 3, and the supporting cellular board 21 and the inserted cellular board 22 of the enclosure system 2 can be completely disassembled, and all paper components can be laid flat and folded, greatly reducing the volume of the empty box and solving the pain points of traditional wooden boxes, such as high weight, high cost of empty box transportation, and high transportation energy consumption. Moreover, all components of the stackable cellular carton are made of paper materials, and the recycling rate is much higher than that of traditional wooden boxes, fully meeting the development concept of green logistics.

[0043] Further, in the actual production of the stackable cellular carton, the enclosure system can correspondingly increase the cellular reinforcing rib 232 between the two insertion slots 23 of the supporting cellular board 21 according to its size, to improve the overall support performance of the enclosure system.

[0044] Although the aforementioned fence system 2 has realized the basic load bearing and detachable functions through the composite structure of the insertion slot 23, there are still some defects in long-term cyclic use or large height specification box application scenarios, that is, the second extension sheet body 2312 only relies on the corner part to realize rigid self-maintenance, and the insertion honeycomb plate 22 and the second extension sheet body 2312 do not adopt an adhesive fixing design, which causes the lateral load borne by the insertion honeycomb plate 22 to be directly conducted to the corner node of the outer paper corner guard 231, thereby causing the included angle between the second extension sheet body 2312 and the first adhering sheet body 2311 to expand and deform, or the whole outer paper corner guard 231 to be deflected, and finally causing micro-deformation at the insertion part. This problem will weaken the bonding strength of the insertion honeycomb plate 22 and the supporting honeycomb plate 21, and directly affect the stability and durability of the whole box structure.

[0045] Please refer to Figures 3-6 Therefore, in the present embodiment, at least one reinforcing triangular member 4 is arranged in the insertion slot 23 along the height direction of the supporting honeycomb plate 21. The reinforcing triangular member 4 has a right-angled triangular cross section, which includes a first right-angled adhering surface 41 fixedly adhered to the inner side surface of the second extension sheet body 2312, a second right-angled adhering surface 42 fixedly adhered to the inner side surface of the supporting honeycomb plate 21, and an oblique abutting surface 43 arranged between the first right-angled adhering surface 41 and the second right-angled adhering surface 42 away from the common connecting vertex. The side edge of the insertion honeycomb plate 22 is provided with a matching embedded cutout 221 corresponding to each reinforcing triangular member 4, and the depth of the embedded cutout 221 is not less than 90% of the thickness of the reinforcing triangular member 4, so as to ensure that the oblique abutting surface 43 can tightly abut against the inner wall of the embedded cutout 221.

[0046] With the design of the reinforcing triangular member 4, the stacked honeycomb paper box utilizes the excellent anti-deformation performance of the right-angled triangular structure, forms firm adhesion with the inner side surfaces of the second extension sheet body 2312 and the supporting honeycomb plate 21 through the two right-angled adhering surfaces, and constructs a stable triangular support node. The triangular support node can effectively resist the lateral load transmitted by the insertion honeycomb plate 22, and inhibit the expansion of the included angle between the second extension sheet body 2312 and the first adhering sheet body 2311 and the deflection of the outer paper corner guard 231; at the same time, through the close fitting of the embedded cutout 221 and the oblique abutting surface 43, the front and back, left and right, and up and down displacement degrees of freedom of the insertion honeycomb plate 22 in the insertion slot 23 are limited, and the bonding strength of the insertion honeycomb plate 22 and the supporting honeycomb plate 21 is greatly improved.

[0047] In addition, the enhanced triangular component 4 is fully compatible with the original detachable design logic. When disassembled, the plug-in honeycomb panel 22 only needs to be pulled out horizontally along the plug-in slot 23 to separate the embedded cutout 221 from the enhanced triangular component 4, which is convenient to operate and does not affect the volume compression effect after disassembly and folding of each component. It still maintains the advantages of low transportation cost, high recycling rate and green environmental protection. Finally, without sacrificing the benefits of the original core technology, the weak defect of the original structure plug-in slot 23 in the lateral load resistance is compensated for, making the high load-bearing performance of the box more universal and reliable.

[0048] Please refer to Figures 5-7 , further, in the embodiment, the inner paper corner 2322 close to the first laminated sheet body 2311 is defined as the reinforced inner corner 7, and the enhanced triangular component 4 is composed of a corrugated paper base material integrally formed on the side edge of the reinforced inner corner 7 through continuous bending. Specifically, as shown in Figure 7 , it is a schematic view of the reinforced inner corner 7 and the enhanced triangular component 4 after being flattened), the corrugated paper base material is sequentially separated by the first crease 5, the second crease 51, the third crease 52, the fourth crease 53 to form the first sheet body 71, the second sheet body 72, the third sheet body 44, the fourth sheet body 45 and the fifth sheet body 46. The first sheet body 71 and the second sheet body 72 are bent to form the main structure of the reinforced inner corner 7, the third sheet body 44, the fourth sheet body 45 and the fifth sheet body 46 are bent to form the enhanced triangular component 4 with a right-angled triangular cross section, and the third sheet body 44 forms the oblique contact surface 43 of the enhanced triangular component 4.

[0049] Based on the above design, the third sheet body 44 forms a pulling connection relationship between the second extension sheet 2312 and the reinforced inner corner 7. When the plug-in honeycomb panel 22 is inserted into the plug-in slot 23, the inner wall of the embedded cutout 221 on the side edge of the plug-in honeycomb panel 22 tightly contacts the oblique contact surface 43 of the enhanced triangular component 4, which drives the third sheet body 44 to slightly elastically deform, thereby forming a pulling force on the second extension sheet 2312, so that the second extension sheet 2312 is tightly attached to the side surface of the plug-in honeycomb panel 22, and the connection strength between the two is enhanced; during transportation, when the plug-in honeycomb panel 22 bears a lateral load, the integrally formed enhanced triangular component 4 can quickly and uniformly conduct the load to the “force-reinforced support node” described above through the stable connection of the reinforced inner corner 7 with the supporting honeycomb panel 21 and the second extension sheet 2312, effectively inhibiting the expansion of the included angle between the second extension sheet 2312 and the first laminated sheet body 2311, avoiding micro-deformation at the plug-in part, and significantly enhancing the overall rigidity and load-bearing stability of the surrounding plate system 2.

[0050] The reinforced inner corner 7 and the reinforcing triangular member 4 are designed in one-piece, without additional connecting components, which simplifies the production process and assembly procedure, reduces the manufacturing cost, and further improves the structural reliability and use economy of the box.

[0051] Please refer to Figure 8 In the embodiment, the inner wall of the embedded cutout 221 is bonded with a reinforcing layer 6 made of single or double corrugated paperboard, which is fixed to the inner wall of the embedded cutout 221 by full bonding. The single or double corrugated paperboard has excellent compression strength, wear resistance and energy absorption characteristics due to the three-dimensional support structure of the corrugated core layer, and forms a firm integrated structure with the inner wall of the embedded cutout 221 by full bonding, which greatly improves the local structural strength and wear resistance of the embedded cutout 221.

[0052] Please refer to Figure 9 In one or more embodiments, an enhanced strip 61 is integrally formed between two reinforcing layers 6 at the same height in the same plug-in honeycomb plate 22, which is located on the inner side of the plug-in honeycomb plate 22 and is fixed to the plug-in honeycomb plate 22 by full bonding. The enhanced strip 61 and the two reinforcing layers 6 form a transverse support structure after being integrally formed, which not only firmly connects the two reinforcing layers 6 at the same height as a whole, greatly improves the overall structural strength and anti-deformation ability of the corresponding height area of the plug-in honeycomb plate 22, avoids local warping or displacement caused by independent stress of the two reinforcing layers 6, but also significantly improves the anti-peeling ability and overall structural reliability of the plug-in part, prolongs the service life of the box under the scene of high-frequency cycle plugging and heavy radial stress.

[0053] In the embodiment, the outer paper corner 231 and the inner paper corner 2322 are both made of high-strength corrugated corners, and their heights are consistent with the height of the supporting honeycomb plate 21. With the excellent bending and compression resistance of the high-strength corrugated corner, and the full height matching design, the edge support of the surrounding plate system 2 can be uniform and stable within the full height range.

[0054] In the embodiment, the supporting honeycomb plate 21, the plug-in honeycomb plate 22, the honeycomb strip 2321, the upper cover 1 and the base 3 all use paper honeycomb plates as the core material. The stacked honeycomb paper box eliminates the support breakpoint through the continuous bonding structure of the height of the honeycomb strip 2321 and the height of the supporting honeycomb plate 21, and the continuous bonding structure of the honeycomb strip 2321 and the supporting honeycomb plate 21, so that the cushioning and compression resistance characteristics of the honeycomb strip 2321 can be uniformly exerted in the full height direction, and the overall structural integrity and stress transmission efficiency of the surrounding plate system 2 are improved.

[0055] In the embodiment, the lower surface of the upper cover 1 is provided with a first recessed clamping groove (not shown) matched with the top of the fence system 2, and the upper surface of the base 3 is provided with a second recessed clamping groove (not shown) matched with the bottom of the fence system 2. Through the embedding of the first and second recessed clamping grooves and the upper and lower ends of the fence system 2, a close limiting and restraining structure can be formed, effectively limiting the displacement of the fence system 2 in the radial direction.

[0056] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical solutions and the inventive concept of the present application, which should be covered within the protection scope of the present application.
