Description

Technical Field

[0001] This utility model belongs to the field of packaging carton technology, specifically a reinforced cardboard structure for packaging carton. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and there are various specifications and models. Cardboard boxes commonly have three or five layers, while seven layers are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while corrugated paper is used for the core paper. The color and feel of each type of paper are different, and the paper produced by different manufacturers also varies in color and feel.

[0003] In the field of modern logistics and commodity transportation, packaging cartons are the most widely used transport packaging materials. Their structural strength and protective performance directly affect the safety of cargo transportation. In actual use, these cartons have many defects: on the one hand, cartons are easily subjected to collisions and compression during handling, stacking and transportation. Due to the lack of effective reinforcement measures, they are prone to damage and deformation, which leads to a decrease in the overall structural strength of the cartons. Consequently, they cannot provide reliable protection for the goods inside, and it is still difficult to ensure the stability of the cartons under complex stress conditions.

[0004] Therefore, a reinforced cardboard structure for packaging cartons is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a reinforced cardboard structure for packaging cartons, which has the advantage of reinforcing the packaging cartons and preventing deformation or collapse of the cartons when they are subjected to collisions or compression during handling, stacking or transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reinforced cardboard structure for packaging cartons, comprising a carton body, with reinforcing strips installed at the four inner corners of the carton body, reinforcing strips installed at the four outer corners of the carton body, an inner plate installed between the four reinforcing strips, and several support strips evenly installed between the four reinforcing strips. The carton body has an internal cavity, and several pressure-resistant strips are evenly installed inside this cavity. A grid plate is fitted into the cavity inside the carton body, and the surface of the grid plate has slots adapted to the pressure-resistant strips. The pressure-resistant strips are fitted into the slots on the surface of the grid plate. A thickened cardboard first is installed at the bottom of the carton body, and a thickened cardboard second is installed at the top of the carton body.

[0007] Preferably, the corners of the reinforcing strip and the strengthening strip are rounded.

[0008] Preferably, both the support bar and the inner plate are made of cardboard.

[0009] Preferably, a rubber pad is installed on the outer surface of the inner plate.

[0010] Preferably, the support strip protrudes outward from the surface of the carton body, forming a raised structure that facilitates gripping.

[0011] Preferably, the grid plate adopts a sloped grid structure.

[0012] Preferably, a wear-resistant plate is installed on the outer surface of the support bar.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model reinforces the carton body by setting up reinforcing strips, strengthening strips and inner plates, so as to prevent the carton body from deforming or collapsing when it is subjected to collision or compression during handling, stacking or transportation, and further enhance the overall compressive strength and stability of the carton body, and ensure the structural integrity of the carton when carrying heavy objects.

[0015] 2. This utility model, by setting up structures such as rubber pads and support strips, not only increases the support of the carton body, but also facilitates the handling of the carton body by operators, further improving the convenience of the carton body, providing stable and reliable gripping points, and effectively reducing the shaking and collision of goods during transportation, thus playing a buffering and protective role.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 As shown, this utility model provides a reinforced cardboard structure for packaging cartons, including a carton body 1. Reinforcing strips 2 are installed at the four inner corners of the carton body 1, and reinforcing strips 3 are installed at the four outer corners of the carton body 1. An inner plate 4 is installed between the four reinforcing strips 2, and several support strips 5 are evenly installed between the four reinforcing strips 3. A cavity is opened inside the carton body 1, and several pressure-resistant strips 6 are evenly installed inside this cavity. A grid plate 7 is snapped into the cavity inside the carton body 1. The surface of the grid plate 7 has slots that match the pressure-resistant strips 6, and the pressure-resistant strips 6 are snapped into the slots on the surface of the grid plate 7. Thickened cardboard 10 is installed at the bottom of the carton body 1, and thickened cardboard 21 is installed at the top of the carton body 1. This reinforces the carton body 1, preventing deformation or collapse during handling, stacking, or transportation when subjected to collisions or compression, and further enhancing the overall compressive strength and stability of the carton body 1.

[0025] Specifically, the corners of both reinforcing strip 2 and reinforcing strip 3 are rounded to prevent sharp edges from scratching operators or damaging other items during handling.

[0026] like Figures 1 to 6 As shown, both the support strip 5 and the inner plate 4 are made of cardboard. The cardboard material of the support strip 5 and the inner plate 4 improves the overall support and makes it less prone to collapse, thus providing strong reinforcement.

[0027] Furthermore, the outer surface of the inner panel 4 is equipped with rubber pads 8, which can effectively reduce the shaking and collision of goods during transportation and play a buffering and protective role.

[0028] It is worth noting that the support bar 5 protrudes outward from the surface of the carton body 1, forming a raised structure that is easy to grip, thereby facilitating the handling of the carton body 1 by operators and further improving the convenience of the carton body 1.

[0029] like Figures 1 to 6 As shown, the grid plate 7 adopts a sloping grid structure, which can provide better support and reduce the overall weight of the carton body 1 to a certain extent, making it easier to handle and transport.

[0030] It is worth emphasizing that the outer surface of the support bar 5 is equipped with a wear-resistant plate 9. The wear-resistant plate 9 can ensure that the support bar 5 is not easily damaged after repeated handling and gripping, and can protect the support bar 5 from damage caused by external friction, providing a stable and reliable gripping point.

[0031] Working principle and process: The items to be packaged are placed inside the carton body 1. Due to the presence of the rubber pad 8, the shaking and collision of the goods during transportation can be effectively reduced, playing a buffering and protective role. The inner plate 4 provides support for the interior of the carton body 1.

[0032] The reinforcing strips 2 at the four inner corners of the cardboard box body 1 and the reinforcing strips 3 at the four outer corners, together with the support strips 5, provide support and reinforcement for the edges and corners and the overall exterior of the cardboard box body 1, effectively dispersing external pressure and preventing the edges and corners of the cardboard box from deforming or breaking during stacking and transportation.

[0033] The rounded corner structure of reinforcing strip 2 and reinforcing strip 3 eliminates sharp edges and corners, which can prevent scratches to operators or other items during handling and storage, and reduce the risk of corner cracking caused by stress concentration.

[0034] When the carton body 1 is subjected to external pressure, the pressure is transmitted to the grid plate 7 and the anti-compression strip 6. The grid plate 7 uses its inclined grid structure to evenly distribute the pressure to the side walls and bottom of the entire carton body 1, avoiding local stress concentration that could cause the carton to deform or break. This allows the packaging carton to withstand greater weight during transportation and storage, further enhancing the overall compressive strength and stability of the carton and preventing deformation under stress. The anti-compression strip 6 can prevent pressure from entering the interior of the carton body 1, greatly improving the compressive strength of the carton body 1.

[0035] The grid plate 7 adopts a sloping grid structure, which can provide better support, decompose the force into components along the sloping surface, improve the compression resistance of the carton side, and reduce the overall weight of the carton body 1 to a certain extent, making it easier to handle and transport.

[0036] The thickened cardboard 10 at the bottom and the thickened cardboard 21 at the top are designed to meet the load-bearing requirements at the bottom and the pressure resistance requirements at the top, respectively. They can withstand the weight of the internal items and the pressure of the upper stack during handling, ensuring the structural integrity of the carton when carrying heavy objects, preventing damage at the bottom and top, and further increasing the structural support of the carton body 1.

[0037] During handling, operators can directly grasp the protruding support bar 5. The wear-resistant plate 9 can ensure that the support bar 5 is not easily damaged after repeated handling and grasping, and can protect the support bar 5 from damage caused by external friction, providing a stable and reliable gripping point, facilitating the handling process, and extending the service life of the carton body 1.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
