Description

Technical Field

[0001] This application relates to the field of cardboard box manufacturing technology, and more specifically, to a structurally stable, high-strength, compression-resistant cardboard box. Background Technology

[0002] Cardboard boxes are the most widely used packaging products, usually used as wrapping materials for goods or as outer protective layers for items. The physical performance indicators of packaging cardboard boxes are the basis for their quality assessment. Basic test items include appearance, dimensions, flap folding endurance, thickness, bursting strength, puncture strength, etc.

[0003] In related technologies, in order to solve the problem of unstable and non-compression-resistant cardboard box structure, for example, the prior art patent with publication number CN217075268U provides a structurally stable high-strength compression-resistant cardboard box. This device solves the problem of unstable and non-compression-resistant cardboard box structure by setting a reinforcing structure inside the cardboard box body and a protective structure at the bottom of the cardboard box body.

[0004] While the aforementioned existing technical solutions have solved some of the defects of traditional cardboard boxes, the excessive number of parts will have negative impacts on multiple dimensions, including cost. The increased number of parts means increased raw material consumption, and at the same time, it adds parts processing steps and multi-component adaptation and debugging steps, which prolongs the production cycle and leads to an increase in production time and equipment wear and tear costs per unit product.

[0005] In view of this, we propose a structurally stable, high-strength, compression-resistant cardboard box. Utility Model Content

[0006] The purpose of this application is to provide a structurally stable, high-strength, compression-resistant cardboard box that can effectively solve the problem of increased costs due to excessive cardboard box parts in the prior art, and achieve the effect of reducing costs by simplifying cardboard box parts.

[0007] This application provides a structurally stable, high-strength, compression-resistant cardboard box, comprising: Cardboard box base; The cardboard box body is disposed on top of the cardboard box base; A lid is provided on top of the carton body. The carton body includes an outer wall and an inner wall, and a through groove, an L-shaped honeycomb plate, a rectangular honeycomb plate, and a reinforcing plate are provided between the outer wall and the inner wall.

[0008] As an optional solution to the technical solution of this application, the outer wall of the outer wall of the carton body is fixedly disposed with the inner wall of the carton base, and the interior of the through groove includes a first connecting groove, a second connecting groove and an installation groove.

[0009] As an optional embodiment of the technical solution in this application, the inner wall of the first connecting groove is fixed to the outer wall of the L-shaped honeycomb panel with adhesive, and the outer wall of the second connecting groove is fixed to the outer wall of the rectangular honeycomb panel with adhesive. The size of the mounting groove is adapted to the size of the reinforcing plate. As an optional solution to the technical solution in this application, the outer wall of the reinforcing plate is provided with a movable groove, and an elastic plate is fixedly provided on the inner wall of the movable groove.

[0010] As an optional solution to the technical solution of this application, an outer wallpaper corner protector is fixedly provided at the outer corner of the outer wall of the carton body, and an inner corner wallpaper corner protector is fixedly provided on the inner wall of the inner wall of the carton body. The bottom of the outer wallpaper corner protector is fixedly provided to the top of the carton base.

[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: The cardboard box body of this application adopts a three-layer composite structure consisting of the outer wall of the cardboard box body, the through-slot, and the inner wall of the cardboard box body. The L-shaped honeycomb panel, the rectangular honeycomb panel, and the reinforcing plate are precisely positioned and fixed inside through the through-slot, forming a multi-directional force support system. When the cardboard box is subjected to external vertical pressure or lateral extrusion pressure, the pressure is first transmitted to the through-slot through the outer wall of the cardboard box body. The L-shaped honeycomb panel corresponds to the corner area of ​​the cardboard box, and the rectangular honeycomb panel corresponds to the flat area of ​​the box body. Utilizing the hexagonal mechanical stability characteristics of the honeycomb structure, the concentrated stress is dispersed into surface stress, avoiding box body dents caused by excessive local stress. The reinforcing plate, as a rigid support unit, complements the honeycomb panel, further improving the overall structural strength of the box body and preventing overall deformation of the box body under heavy load or stacking conditions.

[0012] The corners of the cardboard box are critical areas where stress is concentrated and deformation is easily caused. This application addresses this issue with a dual corner protection design, using both outer and inner corner protectors. The outer corner protector is fixed to the corner of the outer wall of the cardboard box and rigidly connected to the base, forming impact protection for the outer corners of the box and preventing damage to the outer wall caused by corner collisions during handling or stacking. The inner corner protector is fixed to the corner of the inner wall of the cardboard box, complementing the outer corner protector and further strengthening the structural strength of the corner area. This prevents a decrease in the box's sealing performance or overall structural failure due to corner deformation. The dual corner protectors are also fixedly connected to the base and the main body of the box, improving the connection stability between the box and the base and preventing separation of the main body from the base during handling.

[0014] The present application will be further described in detail below with reference to the accompanying drawings.

[0015] Reference Figure 1 , Figure 2 and Figure 3 This application discloses a structurally stable, high-strength, compression-resistant cardboard box, comprising a cardboard box base 1, a cardboard box body 2, and a box lid 3. The cardboard box body 2 is disposed on top of the cardboard box base 1. The cardboard box body 2 is disposed on top of the cardboard box body 2. The cardboard box body 2 includes an outer wall 21 and an inner wall 22. A through groove 6, an L-shaped honeycomb plate 7, a rectangular honeycomb plate 8, and a reinforcing plate 9 are provided between the outer wall 21 and the inner wall 22.

[0016] The outer wall of the carton body 21 is fixedly installed with the inner wall of the carton base 1. The interior of the through groove 6 includes a first connecting groove 61, a second connecting groove 62 and an installation groove 63.

[0017] The inner wall of the first connecting groove 61 is fixed to the outer wall of the L-shaped honeycomb panel 7 with glue. The outer wall of the second connecting groove 62 is fixed to the outer wall of the rectangular honeycomb panel 8 with glue. The size of the mounting groove 63 is adapted to the size of the reinforcing plate 9.

[0018] The internal structure of the carton base 1 is the same as that of the carton body 2.

[0019] The main body 2 of the carton adopts a three-layer composite structure of outer wall 21, through groove 6, and inner wall 22. Through groove 6 precisely positions and fixes L-shaped honeycomb panel 7, rectangular honeycomb panel 8 and reinforcing plate 9 to form a multi-directional force support system. External vertical and horizontal pressure is transmitted to through groove 6 through outer wall 21. The honeycomb panel disperses concentrated stress into surface stress by means of hexagonal mechanical stability, avoiding local depression. The reinforcing plate 9 complements the honeycomb panel, improves the overall strength of the carton, and prevents overall deformation when under heavy load or stacked.

[0020] Reference Figure 2 , Figure 3 and Figure 4 The outer wall of the reinforcing plate 9 is provided with a movable groove 91, and the inner wall of the movable groove 91 is fixedly provided with an elastic plate 92.

[0021] A movable groove 91 is provided on one side of the reinforcing plate 9. An elastic plate 92 is installed in the movable groove 91. The elastic plate 92 has an arc-shaped protrusion structure, and its protrusion direction faces the inner wall of the mounting groove 63. When the reinforcing plate 9 is inserted into the preset assembly position along the axial direction of the mounting groove 63, the elastic plate 92 is squeezed by the inner wall of the mounting groove 63 and undergoes elastic deformation, thereby applying a continuous and uniform radial preload to the inner wall of the mounting groove 63. The static friction between the elastic plate 92 and the inner wall of the mounting groove 63 achieves reliable positioning and fixation of the reinforcing plate 9 in the mounting groove 63, effectively preventing the reinforcing plate 9 from axial movement or circumferential rotation due to vibration, impact and other factors during equipment operation, and significantly improving the stability and connection strength of the assembly structure.

[0022] Reference Figure 1 and Figure 2 An outer wallpaper corner protector 4 is fixedly installed at the outer corner of the outer wall 21 of the carton body, and an inner corner wallpaper corner protector 5 is fixedly installed on the inner wall of the inner wall 22 of the carton body. The bottom of the outer wallpaper corner protector 4 is fixedly installed at the top of the carton base 1.

[0023] The corners of cardboard boxes are critical areas where stress is concentrated and deformation is easily caused. This application adopts a double corner protection design with outer paper corner protectors 4 and inner paper corner protectors 5 to specifically solve the problem of corner protection: the outer paper corner protectors 4 are fixed to the corner of the outer wall 21 of the cardboard box body and the cardboard box base 1 to achieve impact protection of the external corners and avoid damage to the outer wall caused by collision. The inner paper corner protectors 5 are fixed to the corner of the inner wall 22 of the cardboard box body, echoing the outer paper corner protectors 4 to strengthen the corner structure and prevent deformation from causing a decrease in sealing performance or structural failure. The double corner protectors are fixedly connected to the cardboard box base 1 and the main body 2, which simultaneously improves the connection stability between the box body and the base and prevents the two from separating during handling.

[0024] In summary, the high-strength, compression-resistant cardboard box with stable structure disclosed in this application has a three-layer composite structure design for the main body 2: outer wall 21, through groove 6, and inner wall 22. The through groove 6 enables precise positioning and embedding of the L-shaped honeycomb panel 7 and the rectangular honeycomb panel 8, forming a multi-directional force-bearing support system. Simultaneously, a reinforcing plate 9 can be inserted into the mounting groove 63. One side of the reinforcing plate 9 has a movable groove 91, within which is fitted an elastic plate 92 with an arc-shaped protrusion facing the mounting groove 6. 3. Inner wall: When the reinforcing plate 9 is inserted into the preset assembly position along the axial direction of the mounting groove 63, the elastic plate 92 is squeezed by the inner wall of the mounting groove 63 and generates elastic deformation, thereby applying a continuous and uniform radial preload to the inner wall of the mounting groove 63. With the help of the static friction between the elastic plate 92 and the inner wall of the mounting groove 63, the reinforcing plate 9 is reliably positioned and fixed in the mounting groove 63, effectively avoiding the axial movement or circumferential rotation of the reinforcing plate 9 caused by vibration, impact and other factors during equipment operation, and significantly improving the stability and connection strength of the assembly structure. When the carton is subjected to external vertical pressure or lateral extrusion, the pressure is first transmitted to the inside of the through groove 6 through the outer wall 21 of the carton body: L-shaped honeycomb plate 7 corresponds to the corner area of ​​the carton and rectangular honeycomb plate 8 corresponds to the flat area of ​​the carton body. By making full use of the hexagonal mechanical stability characteristics of the honeycomb structure, the concentrated stress is dispersed into surface stress, avoiding the carton body dent caused by excessive local stress. The reinforcing plate 9 serves as a rigid support unit and complements the honeycomb plate, further improving the overall structural strength of the carton body and preventing the carton body from deforming under heavy load or stacking conditions. The corners of cardboard boxes are critical areas where stress is concentrated and deformation is common. This application addresses the corner protection problem through a dual corner protection design using outer paper corner protectors 4 and inner paper corner protectors 5. The outer paper corner protectors 4 are fixed to the corners of the outer wall 21 of the cardboard box body, and their bottoms are rigidly connected to the cardboard box base 1, forming impact protection for the outer corners of the box body. This prevents damage to the outer wall caused by corner collisions during handling or stacking. The inner paper corner protectors 5 are fixed to the corners of the inner wall 22 of the cardboard box body, complementing the outer paper corner protectors 4 to further strengthen the structural strength of the corner area. This prevents a decrease in the box's sealing performance or overall structural failure caused by corner deformation. The fixed connection design of the dual corner protectors with the cardboard box base 1 and the cardboard box body 2 also improves the connection stability between the box body and the base, effectively preventing the body from separating from the base during handling.
