Description
Technical Field
[0001] This utility model relates to the field of corrugated watermarked carton technology, and in particular to a corrugated watermarked carton that is easy to die-cut. Background Technology
[0002] Corrugated cardboard boxes, as one of the most commonly used packaging containers, play a vital role in commodity transportation and warehousing due to their low cost, light weight, and ease of mass production. Traditional corrugated cardboard boxes are manufactured using an integrated die-cutting process, and their main structural strength comes from the internal corrugated core paper. This wavy, arched structure can effectively disperse pressure from the vertical direction, giving the cardboard box good top compression resistance and cushioning performance, which is the basis for its widespread application.
[0003] However, the excellent mechanical properties imparted by the corrugated structure are highly directional. Its superior support capacity is mainly reflected in the vertical direction parallel to the corrugation direction. When the carton is subjected to lateral squeezing or torsional forces during stacking or transportation, the lack of different effective support structures in the lateral dimension makes the carton very prone to lateral crushing, bulging, or twisting deformation. This inherent structural shortcoming not only affects the aesthetics of the packaging, but more seriously, it leads to damage to the goods inside. This deficiency is particularly prominent when carrying heavy items or facing complex logistics environments.
[0004] Therefore, this utility model proposes a corrugated watermarked carton that is easy to die-cut to overcome the shortcomings of the prior art. Utility Model Content
[0005] In view of the problem that the existing corrugated watermarked carton, which is easy to die-cut, has insufficient lateral compressive strength and overall torsional resistance due to its reliance on only unidirectional corrugation support, this utility model aims to provide a corrugated watermarked carton with an improved structure that can effectively solve the above problems and is easy to die-cut.
[0006] This utility model provides a corrugated watermarked carton that is easy to die-cut, comprising: a bottom plate, side panels and a watermark layer; as well as corrugated paper and structural rods.
[0007] The extension direction of the structural rod is perpendicular to the corrugation direction of the corrugated paper.
[0008] Furthermore, the corrugated paper and the structural rod are combined in a manner similar to that between the base plate and the watermark layer.
[0009] Preferably, the corrugated paper and the structural rod are integrated into the sandwich structure of the base plate.
[0010] Preferably, the corrugated watermarked carton that is easy to die-cut also includes a top half plate, which extends integrally from the end of the side panel away from the bottom plate and is used to close the top of the box.
[0011] Preferably, the corrugated watermarked carton that is easy to die-cut further includes a folding seam, which is disposed between the bottom plate and the side panel and between adjacent side panels, to provide a reference for folding each wall panel of the carton.
[0012] Preferably, the corrugated watermarked carton that is easy to die-cut further includes an adhesive strip that extends integrally from the edge of one of the side panels for bonding and fixing the carton body.
[0013] Furthermore, the edge of the other side panel that mates with the adhesive strip is provided with a relief groove to provide accommodating space for the folding of the adhesive strip.
[0014] As one specific implementation, an angled section is provided at the intersection of the fold seams to prevent interference between the components during folding.
[0015] Preferably, the corrugated paper is used to provide vertical support, and the structural rod is used to provide lateral support.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model solves the problem of insufficient lateral compressive strength and overall torsional resistance of existing corrugated cardboard boxes by setting corrugated paper and structural rods perpendicular to it in the interlayer of the cardboard box, thereby achieving the technical effect of comprehensively improving the overall structural strength of the cardboard box and enabling it to withstand greater loads.
[0018] 2. This utility model, by adopting integrated die-cutting and pre-setting the clearance groove and oblique auxiliary structure, solves the problems of interference and low efficiency in traditional carton assembly, and achieves the technical effect of quick folding and forming without complicated operations, significantly improving packaging efficiency.
[0019] 3. This utility model optimizes the internal structure by using local reinforcing ribs, which solves the problem of high cost and bulky box caused by relying on overall thickening of cardboard to improve strength in traditional methods. It achieves the technical effect of significantly enhancing structural performance while effectively controlling material cost and weight. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0027] Example:
[0028] Please refer to Figures 1 to 4 The corrugated watermarked carton, which is easy to be die-cut, is integrally die-cut from a single sheet of cardboard. It includes a base plate 1 and side panels 2 that extend integrally and are foldably connected to the base plate 1. The base plate 1 serves as the load-bearing foundation of the entire carton, while the side panels 2 are used to form the vertical walls of the carton after folding.
[0029] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the bottom plate 1 of the corrugated watermark carton that is easy to be die-cut and formed further includes a composite reinforcing structure, and the composite reinforcing structure forms a specific layered integration relationship between the bottom plate 1 and the outer surface of the carton.
[0030] Please refer to Figure 2 and Figure 3 The structure will be explained in detail below:
[0031] The corrugated watermarked carton, which is easy to die-cut, also includes a watermark layer 6, which covers the outer surface of the base plate 1. A corrugated paper 4 and a structural rod 5 are integrally formed between the base plate 1 and the watermark layer 6. The corrugated paper 4 has wavy corrugations extending in a specific direction to provide vertical support. The structural rod 5 extends perpendicularly to the corrugation direction of the corrugated paper 4 to provide lateral support.
[0032] In the formed state, the corrugated paper 4 and the structural rod 5 are integrated into the sandwich structure of the base plate 1. This orthogonal combination structure of corrugation and reinforcing ribs ensures that the base plate 1 not only has excellent vertical compressive strength when bearing load, but also has significantly enhanced lateral compressive and torsional strength.
[0033] Based on the above embodiments, the present invention may further include the following preferred technical solutions:
[0034] As a preferred embodiment, for sealing the top of the enclosure, please refer to... Figure 4 The side panel 2, away from the bottom panel 1, also has an integrally extended top half panel 3.
[0035] As a specific implementation method, in order to ensure that each wall panel of the box can be precisely folded and formed, please refer to... Figure 4 Folding seams 7 are pre-installed between the base plate 1 and the side panel 2, as well as between adjacent side panels 2.
[0036] Furthermore, to achieve a reliable adhesive seal on the sides of the enclosure, please refer to... Figure 4 One of the side panels 2 has an integrally extended adhesive strip 8 along its free edge, and the other side panel 2, which cooperates with the adhesive strip 8, has a corresponding relief groove 9 on its edge, which provides space for the adhesive strip 8 to be folded in and pasted.
[0037] As a further limitation of the above scheme, to avoid physical interference between the wall panels during the folding process, please refer to... Figure 4 An angled 10 is provided at the intersection of the fold seam 7.
[0038] Working principle: When producing the carton, it is cut in one piece according to the shape. After cutting, the folding seam 7 is cut accordingly. During assembly, the side panels 2 around the bottom plate 1 are folded upward along the folding seam 7. The top half plate 3 at the other end of the side panel 2 can seal the top of the carton. The corrugated paper 4 and structural rod 5 in the middle of the bottom plate 1 and the watermark layer 6 respectively strengthen the overall structural strength of the carton vertically and horizontally. The adhesive strip 8 can be folded into the relief groove 9 and glued to the inner wall of the side panel 2 on the other side. The bevel 10 prevents the parts from conflicting during folding, realizing quick folding. It adopts one-piece molding and die cutting, which is simple to assemble and has high structural strength.
