Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard boxes, and more particularly to a corrugated cardboard box that is resistant to compression and deformation. Background Technology

[0002] Corrugated boxes are one of the most widely used packaging products. They are made from corrugated cardboard through die-cutting, creasing, stapling, or gluing.

[0003] Existing corrugated cardboard boxes have corrugated cardboard sandwiched in the layers to increase their strength and cushioning capacity. During transportation, corrugated cardboard boxes are often subjected to collisions with other items. These collisions may come from other packages, the shaking of transport vehicles, or rough handling during handling. When corrugated cardboard boxes collide with other items, they will deform under the force, thereby playing a cushioning role, absorbing and dispersing the external impact force, and protecting the contents of the box.

[0004] However, although corrugated cardboard can increase the strength of corrugated boxes, the material of corrugated cardboard itself is still corrugated paper. In a humid environment, corrugated cardboard will inevitably become damp and deformed, which will lead to a decrease in strength and loss of cushioning effect. In addition, the objects that collide with corrugated boxes may be sharp objects. Both corrugated cardboard and corrugated cardboard have weak puncture resistance and cannot provide sufficient protection.

[0005] While other materials can be used, such as plastic to make corrugated cardboard-like sheets to replace corrugated cardboard and improve the strength and puncture resistance of corrugated boxes, and plastic sheets can also provide some cushioning, further improving their compressive strength or enhancing their cushioning effect would require continuously thickening the plastic sheets, which would increase the weight of the corrugated boxes and raise transportation costs. Summary of the Invention

[0006] The purpose of this application is to provide a corrugated cardboard box that is resistant to compression and deformation to solve the above problems. The specific technical solution is as follows:

[0007] A corrugated cardboard box resistant to compression and deformation includes a bottom cardboard and several side cardboards connected to the bottom cardboard. The side cardboard includes a first flat cardboard and a second flat cardboard arranged in parallel, and a cotton thread located between the first flat cardboard and the second flat cardboard. Several elastic cushioning members are connected to the cotton thread and arranged side by side. Each elastic cushioning member includes two connecting ends and an arc-shaped elastic connecting bridge. The two connecting ends are symmetrically installed at both ends of the elastic connecting bridge, and the two connecting ends are fixedly sleeved on the cotton thread to cause the elastic connecting bridge to bulge and deform. Each pair of adjacent elastic cushioning members forms a support group. The two elastic cushioning members in any support group are centrally symmetrically arranged and abut against the first flat cardboard and the second flat cardboard, respectively.

[0008] Preferably, the cotton thread includes a first branch thread and a second branch thread.

[0009] Preferably, it also includes a silicone tube, which is sleeved on the cotton thread and disposed between the two connecting ends of the elastic buffer.

[0010] Preferably, the bottom cardboard is rectangular, and four side cardboards are vertically connected to the top surface of the bottom cardboard. The four side cardboards are arranged along the edge of the bottom cardboard, and two adjacent side cardboards are connected to each other and have an overlapping area. A fixing rod is provided in the overlapping area and is vertically connected to the bottom cardboard. The cotton thread in two adjacent side cardboards is bound to the fixing rod.

[0011] Preferably, it further includes a buffer support column, which is arranged perpendicular to the bottom cardboard. Each elastic buffer member is equipped with a plurality of buffer supports, and the buffer supports are arranged on the side opposite to the raised direction of the elastic connecting bridge. One side of the opposite sides of the buffer support column abuts against the silicone tube, and the other side of the opposite sides of the buffer support column is connected to the first flat cardboard or the second flat cardboard.

[0012] Preferably, the buffer support includes a plastic support rod and a silicone layer sleeved on the outside of the plastic support rod.

[0013] Preferably, it also includes a bracket, which is disposed inside the base cardboard. The bracket is square in shape, and a reinforcing rod is connected between two opposite corners of the bracket. The fixing rod passes through the base cardboard and is connected to the bracket.

[0014] Preferably, it also includes a top cover, which is detachably fastened to the corrugated cardboard box, the top end of the fixing rod extending outward through the side cardboard, and the bottom surface of the top cover having a groove for mounting the top end of the fixing rod.

[0015] The beneficial effects of this application are:

[0016] 1. By setting cotton thread and elastic buffer between the first and second flat cardboard, it is ensured that when the side cardboard is impacted or subjected to an impact, the first or second flat cardboard will directly transmit the impact force to the elastic buffer. The elastic connecting bridge in the elastic energy storage state works together with the cotton thread to play a buffering role.

[0017] 2. The elastic buffer is made of plastic, and its elastic connecting bridge is an arc-shaped panel with puncture resistance, providing sufficient protection.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] Please see Figure 1 In this embodiment of the invention, a corrugated cardboard box that is resistant to compression and deformation includes a bottom cardboard 1 and a plurality of side cardboards 2 connected to the bottom cardboard 1. The plurality of side cardboards 2 are vertically connected to the bottom cardboard 1 to form a corrugated cardboard box that can hold items.

[0030] Please see Figure 2-4 In some embodiments, the sideboard 2 includes a plurality of cotton threads 21 arranged side by side and a first flat board 22 and a second flat board 23 respectively arranged on opposite sides of the plurality of cotton threads 21 arranged side by side. Specifically, the cotton threads 21 are located on the middle line of the first flat board 22 and the second flat board 23. By setting the cotton threads 21 between the first flat board 22 and the second flat board 23, the sideboard 2 can play a buffering role when it is subjected to impact or collision. For example, when an external object impacts the first flat board 22 located on the outside, the first flat board 22 will be concave inward and squeeze the cotton threads 21. The cotton threads 21 are elastically deformed under force and apply a reaction force to the first flat board 22 to play a buffering role.

[0031] Preferably, a plurality of elastic buffer members 24 arranged side by side are connected to the cotton thread 21. Each elastic buffer member 24 includes two connecting ends and an arc-shaped elastic connecting bridge. The two connecting ends are symmetrically installed at both ends of the elastic connecting bridge, and the two connecting ends are fixedly sleeved on the cotton thread to cause the elastic connecting bridge to bulge and deform. Alternatively, the middle section of the elastic buffer member 24 can be understood as bulging outward and forming an arc shape to serve as an elastic connecting bridge. Under the tension of the cotton thread 21, the elastic buffer member 24 is in an elastic energy storage state. The elastic connecting bridge of one of the two adjacent elastic buffer members 24 abuts against the first flat cardboard 22. Another elastic buffer 24 has an elastic connecting bridge that abuts against the second flat cardboard 23. That is, the protrusions of two adjacent elastic buffers 24 are opposite or the orientations of two adjacent elastic buffers 24 are opposite. An elastic buffer 24 is added on the basis of the cotton thread 21 to ensure that when the side cardboard 2 is impacted or subjected to an impact, the first flat cardboard 22 on the outside will directly transmit the impact force to the elastic buffer 24. The elastic buffer 24, which is in an elastic energy storage state, can play a buffering role. The elastic buffer 24 itself will deform under force and transfer part of the force to the cotton thread 21. The elastic buffer 24 and the cotton thread 21 work together to play a buffering role.

[0032] It is worth mentioning that the elastic buffer 24 is made of plastic, and the arc-shaped panel formed by its elastic connecting bridge also has puncture resistance, providing sufficient protection.

[0033] To ensure the elastic buffer 24 can be relatively securely mounted on the cotton thread 21, in some preferred embodiments, the cotton thread 21 includes a first branch 211 and a second branch 212. The two connecting ends of the elastic buffer 24 are a first connecting end 241 and a second connecting end 242, respectively. Both the first connecting end 241 and the second connecting end 242 are provided with a first hole 2411 and a second hole 2412 for mounting the first branch 211 and the second branch 212. It is understood that most cotton threads 21 are circular, and mounting the elastic buffer 24 on a single thread is unreliable. If the cotton thread 21 and the elastic buffer... If the connection of component 24 is loose, the elastic buffer component 24 may flip over at any time. However, the cotton thread 21 in this embodiment is composed of a first branch line 211 and a second branch line 212. The elastic buffer component 24 is connected to the first branch line 211 and the second branch line 212. Even if a branch line is not firmly connected to the elastic buffer component 24, it will not rotate or flip over. Furthermore, by setting the first branch line 211 and the second branch line 212 for double-line cooperation, the strength can be improved. When under force, the force is distributed to the first branch line 211 and the second branch line 212. Each branch line bears part of the force, which can improve the strength and make it less prone to breakage.

[0034] Preferably, it also includes a silicone tube 25, which is disposed between the first connecting end 241 and the second connecting end 242. The silicone tube 25 is sleeved on the cotton thread 21, meaning that the silicone tube 25 can also play a buffering role when facing the impact of external objects. This is a buffering role in the first direction. Moreover, the silicone tube 25 also plays a buffering role in the second direction, which will be further explained below:

[0035] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the first connecting end 241 or the second connecting end 242 of one of two adjacent elastic buffers 24 extends between the first connecting end 241 and the second connecting end 242 of the other elastic buffer 24; for example Figure 4As shown, taking the three elastic buffers 24 in this section as an example, the inner surface of the second connecting end 242 of the elastic buffer 24 located in the front abuts against the inner surface of the first connecting end 241 of the elastic buffer 24 located in the middle, while the inner surface of the first connecting end 241 of the elastic buffer 24 located in the rear abuts against the inner surface of the second connecting end 242 of the elastic buffer 24 located in the middle. At this time, the silicone tube 25 that matches the elastic buffer 24 located in the middle is not only set between the first connecting end 241 and the second connecting end 242 of the elastic buffer 24 located in the middle, but also is held in the middle by the second connecting end 242 of the elastic buffer 24 located in the front and the first connecting end 241 of the elastic buffer 24 located in the rear. The elastic buffer 24 is deformed by the impact. While the elastic buffer 24 is flattened, its two ends extend outward along the cotton thread 21 and squeeze the silicone tube 25. The silicone tube 25 can play a buffering role in the second direction.

[0036] In addition, in this embodiment, silicone blocks 4 are sleeved on the outer sides of the two ends near the cotton thread 21, and the silicone blocks 4 limit the elastic buffer 24 at the beginning and end.

[0037] Please see Figure 5 In some embodiments, the bottom cardboard 1 is rectangular, and four side cardboards 2 are vertically connected to the top surface of the bottom cardboard 1. The four side cardboards 2 are arranged along the edge of the bottom cardboard 1. Adjacent side cardboards 2 are connected to each other and have an overlapping area. A fixing rod 28 is provided in the overlapping area and is vertically connected to the bottom cardboard 1. The cotton thread 21 in the two adjacent side cardboards 2 are all tied to the fixing rod 28. Specifically, it also includes a bracket 26, which is set inside the bottom cardboard 1. The bracket 26 is square and its shape is adapted to the shape of the bottom cardboard 1. A reinforcing rod 27 is connected between the two opposite corners of the bracket 26. The fixing rod 28 passes through the bottom cardboard 1 and is connected to the bracket 26. By setting the reinforcing rod 27, the strength of the bracket 26 is strengthened and the load-bearing capacity of the bottom cardboard 1 is improved.

[0038] Please see Figure 6 Preferably, it also includes a top cover 3, which is detachably fastened to the corrugated cardboard box. The top end of the fixing rod 28 extends outward through the side cardboard 2. The bottom surface of the top cover 3 is provided with a groove 31 to install the top end of the fixing rod 28. When the side cardboard 2 is impacted by an external object, the cotton thread 21 will pull the fixing rod 28. At this time, the bottom end of the fixing rod 28 is connected to the bracket 26, while the top end of the fixing rod 28 is fixed in the groove. The fixing rod 28 can provide sufficient support for the cotton thread 21.

[0039] In a preferred embodiment, the system further includes a cushioning support 29, which includes a plastic support rod 291 and a silicone layer 292 sleeved on the outside of the plastic support rod 291. The cushioning support 29 is arranged perpendicular to the bottom cardboard 1. Each elastic cushioning member 24 is equipped with at least three cushioning supports 29, and the cushioning support 29 is located on the side of the elastic cushioning member 24 that is concave inward or on the side that is away from the direction of the elastic connecting bridge. By setting the cushioning support 29, the part of the first flat cardboard 22 and the second flat cardboard 23 that lacks the support of the elastic cushioning member 24 can be filled. The silicone layer 292 can also play a role in absorbing water. One side of the opposite sides of the cushioning support 29 is in contact with the cotton thread 21, and the other side of the opposite sides of the cushioning support 29 is bonded to the first flat cardboard 22 or the second flat cardboard 23. The shape of the cushioning support 29 can be a cuboid or a cylinder.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
