Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard boxes, and more specifically, to a corrugated cardboard box with a suitable volume structure. Background Technology

[0002] For more than half a century, corrugated cardboard boxes have gradually replaced wooden boxes and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also beautify and promote goods. Corrugated cardboard boxes are green and environmentally friendly products, which are beneficial to the environment and easy to load, unload and transport.

[0003] With the continuous development of online shopping and the logistics industry, corrugated cardboard boxes are being used more and more widely. This has led to higher and higher requirements for the function of corrugated cardboard boxes, requiring a corrugated cardboard box with strong compression resistance and reasonable box shape and size. This has also promoted the standardization of the corrugated cardboard box industry, making the box shape and size of corrugated cardboard boxes have certain standards.

[0004] However, the objects being packaged and transported in the current technology vary in shape and size. The existing standardized corrugated cardboard boxes of various shapes and sizes cannot be effectively adapted to these variations. In the actual packaging and transportation process, this can easily lead to waste of packaging materials, thereby reducing the environmental friendliness and recyclability of corrugated cardboard boxes, increasing transportation costs, and raising energy consumption rates. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this invention is to provide a corrugated cardboard box with a volume-adjustable structure. Through the combination of a volume-adjustable belt, a compression-resistant locking bladder, and reinforcing inserts, the corrugated cardboard box can improve its compression strength and extend its service life. Simultaneously, it allows the corrugated cardboard box to have an adjustable volume during use, enabling suitable packaging for objects of different shapes and sizes. This effectively reduces packaging material waste, improves the environmental friendliness of the corrugated cardboard box, and effectively reduces transportation costs and energy consumption.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A corrugated cardboard box with an adjustable volume structure includes a corrugated cardboard box body. An adjustable volume belt is embedded in the middle of the corrugated cardboard box body. A pressure-resistant cavity is formed within the adjustable volume belt. Multiple pressure-resistant locking bladders are fixedly connected within the pressure-resistant cavity. The adjustable volume belt is fixedly connected to the pressure-resistant locking bladders in a contracted state. The pressure-resistant locking bladders are saturated with an impact-binding liquid. Multiple reinforcing teeth are fixedly connected to both the upper and lower ends of the adjustable volume belt. The ends of the reinforcing teeth on both sides extend into the pressure-resistant cavity and are fixedly connected to a puncture cone. The puncture cones cooperate with the pressure-resistant locking bladders. Through the cooperation of the adjustable volume belt, pressure-resistant locking bladders, and reinforcing teeth, the compressive strength of the corrugated cardboard box body can be improved, extending its service life. At the same time, the corrugated cardboard box body has an adjustable volume function during use, enabling suitable packaging for objects of different shapes and sizes. This effectively reduces packaging material waste, improves the environmental friendliness of the corrugated cardboard box body, effectively reduces transportation costs, and reduces energy consumption.

[0010] Furthermore, each of the four corners of the pressure-resistant cavity is fixedly connected with an elastic applicable L-side, and the pressure-resistant locking bladder is located between two corresponding elastic applicable L-sides. The elastic applicable L-sides effectively improve the pressure resistance of the volume applicable belt, reduce the damage rate of the volume applicable belt during use, and also effectively improve the deformation adaptability of the volume applicable belt, making it convenient for volume adjustment of the volume applicable belt.

[0011] Furthermore, the method for increasing the capacity of the corrugated cardboard box body includes the following steps:

[0012] S1. If the user needs to adjust the longitudinal or transverse volume of the corrugated cardboard box;

[0013] S11. The user applies local squeezing force to the middle position of the two parallel surfaces corresponding to the longitudinal or transverse directions of the volume application belt using their fingers or a local squeezing tool;

[0014] S12. The compression locking bladder at the two parallel planes corresponding to the longitudinal or transverse directions is deformed by local extrusion force and punctured by the puncture cone, thereby releasing the limitation of the compression locking bladder on the volume applicable to the two parallel planes corresponding to the longitudinal or transverse directions.

[0015] S13. After the limitation is lifted, the two parallel surfaces of the volume application strip in the corresponding longitudinal or transverse direction have a large elastic deformation range in the corresponding longitudinal or transverse direction, so that the corrugated carton body meets the user's needs.

[0016] S2. If the user needs to make vertical adjustments to the corrugated cardboard box body or simultaneously make both longitudinal and transverse adjustments to the corrugated cardboard box body;

[0017] S21. The user applies local pressure to the center of all four sides of the volume-fitting belt using their fingers or a local squeezing tool;

[0018] S22. This causes all the pressure-locking bladders in the pressure-resistant chamber to deform under local pressure and be punctured by the puncture cone, completely removing the limitation of the pressure-locking bladders on the applicable volume range.

[0019] S23. After the volume-adaptive belt is fully released, its deformation range increases, allowing for volume adjustment both vertically and horizontally simultaneously. This ensures the corrugated box meets the user's needs. Through the action of the anti-compression locking bladder, the user can adjust the volume of the volume-adaptive belt while simplifying the adjustment process, improving the portability of the corrugated box and thus enhancing its functionality and user experience. Furthermore, the increased elasticity of the unlocked volume-adaptive belt further increases the compressive strength of the corrugated box, reducing damage during transportation. This effectively extends the service life of the corrugated box and enhances its protective effect on transported goods, reducing damage rates.

[0020] Furthermore, the reinforcing insert has a reinforcing groove that communicates with the piercing cone. Two connected reinforcing inserts have multiple reinforcing guide holes that communicate with the reinforcing groove at their close ends. After the pressure-resistant locking bladder is punctured, the reinforcing groove can absorb the impact binding liquid and discharge it into the corrugated cardboard box body through the reinforcing guide holes. This not only reduces the impact binding liquid's influence on the deformation of the volumetric applicable belt, but also increases the connection strength between the reinforcing insert and the corrugated cardboard box body, improving the overall integrity of the corrugated cardboard box body.

[0021] Furthermore, an adsorption conduit is fixedly connected to the inner wall of the reinforcing groove on the side away from the pressure-resistant locking bladder, and a conical guide tube is fixedly connected inside the puncture cone. The adsorption conduit extends into the puncture cone from the end near the pressure-resistant locking bladder and is connected to the conical guide tube.

[0022] Furthermore, the outer end of the adsorption conduit is fixedly connected with a plurality of diversion tubes that communicate with the conical guide tube, and the diversion tubes cooperate with the corresponding reinforcing guide holes, with the end of the diversion tube away from the adsorption conduit extending into the reinforcing guide hole.

[0023] Furthermore, multiple elastic guides are fixedly connected to the outer end of the adsorption conduit, and the elastic guides are sleeved on the outside of the corresponding diversion tubes. The end of the elastic guide away from the adsorption conduit extends into the reinforcing guide hole and is fixedly connected to a breakthrough cone. The end of the breakthrough cone near the adsorption conduit abuts against the end of the diversion tube away from the adsorption conduit. By using the diversion tube to guide the impact binding liquid, the elastic guides and breakthrough cones move into the corrugated cardboard box body under the impact of the impact binding liquid, thereby enhancing the toughness of the corrugated cardboard box body and reducing the probability of damage to the corrugated cardboard box body.

[0024] Furthermore, the inner wall of the reinforced guide hole is fixedly connected with an isolation membrane that cooperates with the breakthrough cone. The isolation membrane is located on the side of the breakthrough cone away from the adsorption conduit. The isolation membrane can block the breakthrough cone and the elastic guide strip, so that the unlocked volume application tape and the reinforced insert can be effectively separated from the corrugated carton body. This facilitates the recycling of the corrugated carton body and the volume application tape, reduces the input cost of the corrugated carton body, and improves the reusability and environmental friendliness of the corrugated carton body.

[0025] Furthermore, a saturation elastic band is fixedly connected to the inner wall of the conical guide tube on the side away from the pressure-resistant locking bladder, and the saturation elastic band is slidably connected to the conical guide tube. A pulling wire is fixedly connected to the end of the saturation elastic band near the pressure-resistant locking bladder. The pulling wire extends to the outside of the reinforcing insert at the end near the pressure-resistant locking bladder and is fixedly connected to the pressure-resistant locking bladder. The saturation elastic band remains in a stretched state when the volume applicable band is not unlocked due to the restriction of the pulling wire and the pressure-resistant locking bladder. After the pressure-resistant locking bladder is punctured, the pulling wire releases the restriction on the saturation elastic band, so that the saturation elastic band can effectively absorb the impact traction liquid while generating elastic reset, enhance the adsorption effect of the adsorption conduit on the impact traction liquid, increase the impact force of the impact traction liquid on the breaking cone, effectively extend the range of action of the elastic guide strip, improve its improvement efficiency on the corrugated cardboard box body, and effectively enhance the pressure resistance of the corrugated cardboard box body with adjustable volume, thereby improving the protection of the corrugated cardboard box body.

[0026] Furthermore, the method for recycling the corrugated cardboard box body includes the following steps:

[0027] P1. When the corrugated cardboard box is damaged and recycled during the continuous recycling process;

[0028] P2. The recycling personnel first use tools to remove the damaged ends of the corrugated cardboard box, and retain the undamaged ends of the corrugated cardboard box and the undamaged ends of the corrugated cardboard box.

[0029] P3. Recycling personnel reassemble the corresponding unlocked volume-fitting strips and the undamaged ends of the corrugated cardboard box according to the original dimensions of the corrugated cardboard box body;

[0030] P31. By reinforcing the inserts, the undamaged end of the corrugated cardboard box of the corresponding size is inserted into the unlocked volume-suitable belt;

[0031] P32. Repair the joints with adhesive material, and after the adhesive material dries, quickly assemble the undamaged end of the corrugated cardboard box and the ununlocked volume-fitting belt.

[0032] P4. After being reassembled, the corrugated cardboard box body continues to be used. The damaged ends of the corrugated cardboard box body and the unlocked volume-adjustable belt are recycled, completing the recycling of the corrugated cardboard box body. Through the reinstallation and recycling of the corrugated cardboard box body and the volume-adjustable belt, energy consumption can be effectively reduced, the environmental friendliness of the corrugated cardboard box body can be improved, and the usage cost of the corrugated cardboard box body can be reduced. Furthermore, the unlocked volume-adjustable belt can be used to modify existing non-adjustable corrugated cardboard boxes, reducing the manufacturing cost of the corrugated cardboard box body and effectively improving its economic benefits.

[0033] 3. Beneficial effects

[0034] Compared with the prior art, the advantages of this invention are:

[0035] (1) This solution, through the combination of volume-adaptive belt, pressure-resistant locking bladder and reinforced insert, can improve the pressure resistance of the corrugated carton body and extend its service life, while also enabling the corrugated carton body to have an adjustable volume function during use. It can be used to package objects of different shapes and sizes, effectively reduce the waste of packaging materials, improve the environmental protection of the corrugated carton body, effectively reduce transportation costs and reduce energy consumption.

[0036] (2) The elastic L-side can effectively improve the compressive strength of the volume application belt and reduce the damage rate of the volume application belt during use. At the same time, it can also effectively improve the deformation application of the volume application belt and facilitate the volume adjustment of the volume application belt.

[0037] (3) By using the anti-compression locking pouch, the user can adjust the volume of the volume-fitting belt while simplifying the volume adjustment steps, improving the portability of the corrugated cardboard box, thereby effectively improving the functionality of the corrugated cardboard box and enhancing the user experience.

[0038] (4) Furthermore, since the volume applicable belt after unlocking increases its elastic range, it further increases the compressive strength of the corrugated carton body, reduces the damage rate of the corrugated carton body during transportation, and thus effectively extends the service life of the corrugated carton body while increasing the protective effect of the corrugated carton body on the transported goods and reducing the damage rate of the goods.

[0039] (5) After the pressure-resistant locking bladder is punctured, the reinforcing groove can absorb the impact binding liquid and discharge it into the corrugated carton body through the reinforcing guide hole. This not only reduces the impact binding liquid on the deformation of the volume applicable belt, but also increases the connection strength between the reinforcing insert and the corrugated carton body, and improves the integrity of the corrugated carton body.

[0040] (6) By using the diversion pipe to guide the impact binding liquid, the elastic guide strip and the breaking cone move into the corrugated carton body under the impact of the impact binding liquid, thereby enhancing the toughness of the corrugated carton body and reducing the probability of damage to the corrugated carton body.

[0041] (7) The isolation membrane can block the breakthrough cone and elastic guide strip, so that the unlocked volume application strip and reinforcing insert can be effectively separated from the corrugated carton body, which facilitates the recycling of the corrugated carton body and volume application strip, reduces the input cost of the corrugated carton body, and improves the reusability and environmental friendliness of the corrugated carton body.

[0042] (8) After the pressure-resistant locking bladder is punctured, the pulling wire releases the restriction on the storage elastic band, so that the storage elastic band can effectively adsorb the impact entanglement liquid while generating elastic reset, enhance the adsorption effect of the adsorption conduit on the impact entanglement liquid, increase the impact force of the impact entanglement liquid on the breakthrough cone, effectively extend the range of action of the elastic guide strip, improve its improvement efficiency on the corrugated cardboard box body, effectively enhance the pressure resistance of the corrugated cardboard box body with adjustable volume, and improve the protection of the corrugated cardboard box body.

[0043] (9) By reinstalling and recycling the corrugated cardboard box body and the volume-adaptive belt, energy consumption can be effectively reduced, the environmental friendliness of the corrugated cardboard box body can be improved, the cost of using the corrugated cardboard box body can be reduced, and the existing non-adjustable corrugated cardboard boxes can be modified by using the unlocked volume-adaptive belt, thereby reducing the manufacturing cost of the corrugated cardboard box body and effectively improving the economic benefits of the corrugated cardboard box body.

[0060] Example 1:

[0061] Please see Figure 1-11 A corrugated cardboard box with a volume-adaptive structure includes a corrugated cardboard box body 1. A volume-adaptive belt 2 is embedded in the middle of the corrugated cardboard box body 1. A pressure-resistant cavity 201 is formed inside the volume-adaptive belt 201. Multiple pressure-resistant locking bladders 4 are fixedly connected inside the pressure-resistant cavity 201. The volume-adaptive belt 2 is fixedly connected to the pressure-resistant locking bladders 4 in the vertical contraction state. The pressure-resistant locking bladders 4 are saturated with an impact-binding liquid 401, which is an adhesive liquid, glue, or similar liquid. Multiple reinforcing teeth 3 are fixedly connected to both the upper and lower ends of the volume-adaptive belt 2. The volume-adaptive belt 2 and the reinforcing teeth 3 can be made of silicone, rubber, or other composite materials. The rigidity of the 3 is greater than that of the volume-applicable belt 2. The upper and lower reinforcing inserts 3 extend into the pressure-resistant cavity 201 at one end and are fixedly connected to a piercing cone. The piercing cone cooperates with the pressure-resistant locking bladder 4. Through the cooperation of the volume-applicable belt 2, the pressure-resistant locking bladder 4 and the reinforcing inserts 3, the pressure resistance of the corrugated carton body 1 can be improved and its service life extended. At the same time, the corrugated carton body 1 can also have the function of adjustable volume during use. It can be used to package objects of different shapes and sizes, effectively reduce the waste of packaging materials, improve the environmental protection of the corrugated carton body 1, effectively reduce transportation costs and reduce energy consumption.

[0062] Please see Figure 6 The four corners of the pressure-resistant cavity 201 are fixedly connected with elastic applicable L-sides 202, and the pressure-resistant locking bladder 4 is located between two corresponding elastic applicable L-sides 202. The elastic applicable L-sides 202 can effectively improve the pressure resistance of the volume applicable belt 2 and reduce the damage rate of the volume applicable belt 2 during use. At the same time, they can also effectively improve the deformation applicability of the volume applicable belt 2 and facilitate the volume adjustment of the volume applicable belt 2.

[0063] Please see Figure 1-3 The method for increasing the capacity of the corrugated cardboard box body 1 includes the following steps:

[0064] S1. If the user needs to adjust the longitudinal or transverse volume of the corrugated cardboard box body 1;

[0065] S11. The user applies local squeezing force to the middle position of the two parallel surfaces corresponding to the longitudinal or transverse directions of the volume application band 2 using their fingers or a local squeezing tool;

[0066] S12. The pressure-resistant locking bladder 4 at the two parallel planes corresponding to the longitudinal or transverse directions is deformed by local extrusion force and punctured by the puncture cone, thereby releasing the restriction of the pressure-resistant locking bladder 4 on the two parallel planes corresponding to the longitudinal or transverse directions of the volume applicable belt 2.

[0067] S13. After the limitation is lifted, the two parallel surfaces of the volume applicable strip 2 in the longitudinal or transverse direction have a large elastic deformation range in the longitudinal or transverse direction, so that the corrugated carton body 1 meets the user's needs.

[0068] S2. If the user needs to make vertical or both longitudinal and transverse adjustments to the corrugated cardboard box body 1;

[0069] S21. The user applies local pressure to the center of all four sides of the volume-applicable belt 2 using their fingers or a local squeezing tool;

[0070] S22. This causes all the pressure-locking bladders 4 in the pressure-resistant chamber 201 to deform under local pressure and be punctured by the puncture cone, thus completely releasing the pressure-locking bladders 4 from the limitation of the volume applicable belt 2.

[0071] S23. After the volume-adaptive belt 2 is completely released, its deformation range increases, allowing for volume adjustment both vertically and horizontally simultaneously. This enables the corrugated carton body 1 to meet the user's needs. Through the action of the anti-compression locking bladder 4, the user can adjust the volume of the volume-adaptive belt 2 while simplifying the adjustment process, improving the portability of the corrugated carton body 1, and thus effectively enhancing its functionality and user experience. Furthermore, the increased elasticity of the unlocked volume-adaptive belt 2 further increases the compressive strength of the corrugated carton body 1, reducing the damage rate during transportation. This effectively extends the service life of the corrugated carton body 1, increases its protective effect on transported goods, and reduces the damage rate of the goods.

[0072] Please see Figure 6-11The reinforcing insert 3 has a reinforcing groove 301 that communicates with the piercing cone. Two reinforcing inserts 3 connected to each other have multiple reinforcing guide holes 302 that communicate with the reinforcing groove 301 at their close ends. After the pressure-resistant locking bladder 4 is punctured, the reinforcing groove 301 can absorb the impact binding liquid 401 and discharge it into the corrugated carton body 1 through the reinforcing guide holes 302. This not only reduces the impact binding liquid 401 on the deformation of the volume applicable belt 2, but also increases the connection strength between the reinforcing insert 3 and the corrugated carton body 1, and improves the integrity of the corrugated carton body 1.

[0073] Please see Figure 8-11 An adsorption conduit 5 is fixedly connected to the inner wall of the reinforcing groove 301 away from the pressure-resistant locking bladder 4. A conical guide tube 501 is fixedly connected inside the puncture cone. The adsorption conduit 5 extends into the puncture cone from the end near the pressure-resistant locking bladder 4 and is connected to the conical guide tube 501.

[0074] Please see Figure 8-11 The outer end of the adsorption conduit 5 is fixedly connected with a plurality of diversion tubes 502 that are connected to the conical guide tube 501, and the diversion tubes 502 are matched with the corresponding reinforcing guide holes 302. The end of the diversion tube 502 away from the adsorption conduit 5 extends into the reinforcing guide hole 302.

[0075] Please see Figure 8-11 Multiple elastic guides 6 are fixedly connected to the outer end of the adsorption conduit 5, and the elastic guides 6 are sleeved on the outside of the corresponding diversion tube 502. The end of the elastic guide 6 away from the adsorption conduit 5 extends into the reinforcing guide hole 302 and is fixedly connected to a breakthrough cone 601. The end of the breakthrough cone 601 near the adsorption conduit 5 abuts against the end of the diversion tube 502 away from the adsorption conduit 5. By using the diversion tube 502 to guide the impact binding liquid 401, the elastic guides 6 and the breakthrough cone 601 move into the corrugated cardboard box body 1 under the impact of the impact binding liquid 401, thereby enhancing the toughness of the corrugated cardboard box body 1 and reducing the probability of damage to the corrugated cardboard box body 1.

[0076] Please see Figure 9 and Figure 11 An isolation membrane 7, which cooperates with the breakthrough cone 601, is fixedly connected to the inner wall of the reinforcing guide hole 302. The isolation membrane 7 is located on the side of the breakthrough cone 601 away from the adsorption conduit 5. The isolation membrane 7 can block the breakthrough cone 601 and the elastic guide strip 6, so that the un-unlocked volume application belt 2 and the reinforcing insert 3 can be effectively separated from the corrugated carton body 1. This facilitates the recycling of the corrugated carton body 1 and the volume application belt 2, reduces the input cost of the corrugated carton body 1, and improves the reusability and environmental friendliness of the corrugated carton body 1.

[0077] Please see Figure 8-11A slack elastic band 8 is fixedly connected to the inner wall of the conical guide tube 501 on the side away from the pressure-resistant locking bladder 4, and the slack elastic band 8 is slidably connected to the conical guide tube 501. A pulling wire 801 is fixedly connected to the end of the slack elastic band 8 near the pressure-resistant locking bladder 4. The pulling wire 801 extends to the outside of the reinforcing insert 3 and is fixedly connected to the pressure-resistant locking bladder 4. The slack elastic band 8 remains in a stretched state when the volume applicable band 2 is not unlocked due to the restriction of the pulling wire 801 and the pressure-resistant locking bladder 4. When the pressure-resistant locking bladder 4 is punctured, the slack elastic band 8 remains in a stretched state. Afterwards, the pulling wire 801 releases the restriction on the storage elastic band 8, so that the storage elastic band 8 can effectively adsorb the impact binding liquid 401 while generating elastic reset, enhance the adsorption effect of the adsorption conduit 5 on the impact binding liquid 401, increase the impact force of the impact binding liquid 401 on the breakthrough cone 601, effectively extend the working range of the elastic guide 6, improve its improvement efficiency on the corrugated cardboard box body 1, and effectively enhance the compressive strength of the corrugated cardboard box body 1 with adjustable volume, thereby improving the protective properties of the corrugated cardboard box body 1.

[0078] Please see Figure 4 The method for recycling corrugated cardboard box body 1 includes the following steps:

[0079] P1. When the corrugated cardboard box body 1 is damaged and recycled during the continuous recycling process;

[0080] P2. The recycling personnel first use tools to remove the damaged end of the corrugated cardboard box body 1, and retain the undamaged volume-fitting belt 2 and the undamaged end of the corrugated cardboard box body 1.

[0081] P3. The recycling personnel reassemble the corresponding unlocked volume-fitting strip 2 and the undamaged end of the corrugated cardboard box body 1 according to the original dimensions of the corrugated cardboard box body 1.

[0082] P31. By using the reinforcing insert 3, the undamaged end of the corrugated cardboard box body 1 of the corresponding size is inserted into the volume-suitable belt 2 that has not been unlocked;

[0083] P32. Repair the joints with adhesive material, wait for the adhesive material to dry, and then quickly assemble the undamaged end of the corrugated cardboard box body 1 and the ununlocked volume-fitting belt 2.

[0084] P4. After being reassembled, the corrugated cardboard box body 1 continues to be used. The damaged end of the corrugated cardboard box body 1 and the unlocked volume-adaptive belt 2 are recycled, completing the recycling of the corrugated cardboard box body 1. Through the reinstallation and recycling of the corrugated cardboard box body 1 and the volume-adaptive belt 2, energy consumption can be effectively reduced, the environmental friendliness of the corrugated cardboard box body 1 can be improved, and the usage cost of the corrugated cardboard box body 1 can be reduced. Furthermore, the existing non-adjustable corrugated cardboard boxes can be modified using the unlocked volume-adaptive belt 2, reducing the manufacturing cost of the corrugated cardboard box body 1 and effectively improving its economic benefits.

[0085] Please see Figure 1-11 When the corrugated carton body 1 is not used for volume adjustment, its end face is subjected to the force as a whole during transportation and stacking. This allows the anti-compression locking bladder 4 and the reinforcing insert 3 to decompose the force on the corrugated carton body 1 and the volume application belt 2, thereby increasing the compressive strength of the corrugated carton body 1, reducing the damage of the corrugated carton body 1 during transportation, improving the protection of the corrugated carton body 1, and effectively ensuring the safety of the items inside the corrugated carton body 1.

[0086] When volume adjustment of the corrugated cardboard box body 1 is required, local pressure is applied to compress the anti-compression locking bladder 4, causing it to deform and be punctured by the puncture cone. This releases the restriction on the volume-applicable zone 2, increases its deformation, and effectively adjusts the volume of the corrugated cardboard box body 1. Simultaneously with the puncture of the anti-compression locking bladder 4, the pulling wire 801 releases the restriction on the storage elastic zone 8, causing it to elastically recover and move away from the anti-compression locking bladder 4 within the adsorption conduit 5. Under the combined pressure of the original compression of the anti-compression locking bladder 4 and the adsorption force of the moving storage elastic zone 8, the impact-coupling liquid 401 rapidly enters the adsorption conduit 5 and, guided by the conical guide tube 501, impacts the breaking cone 601, causing the puncture... The breaking cone 601 pierces the release membrane 7 and extends into the corrugated carton body 1. Guided by the breaking cone 601, it releases the impact binding liquid 401, increasing the lateral toughness of the corrugated carton body 1, improving the connection strength between the reinforcing teeth 3 and the corrugated carton body 1, reducing the probability of damage to the corrugated carton body 1, and improving the protective function of the corrugated carton body 1. Through the cooperation of the volume-adjustable belt 2, the pressure-resistant locking bladder 4, and the reinforcing teeth 3, the compressive strength of the corrugated carton body 1 can be improved, its service life extended, and the corrugated carton body 1 can also have an adjustable volume function during use. It can be used to package objects of different shapes and sizes, effectively reducing the waste of packaging materials, improving the environmental friendliness of the corrugated carton body 1, effectively reducing transportation costs, and reducing energy consumption.

[0087] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
