Description

Technical Field

[0001] The invention relates to the technical field of carton packaging, in particular to a high-strength corrugated carton. Background Art

[0002] High-strength corrugated paper boxes are made of at least two flat paperboards and corrugated paper fixed between each two flat paperboards. This kind of paper box is made through specific production processes, such as paper separation, printing, creasing, slit cutting, nailing or gluing. Its structure is strong and can withstand greater weight and pressure.

[0003] The structure of high-strength corrugated boxes includes paperboard, corrugated core, glue, carton structure type, box blank construction and other aspects. The outer layer of the corrugated box is paperboard, which is generally made of high-strength, high-quality kraft paper and other cardboard materials. The middle part of the corrugated box is the corrugated core, that is, corrugated paper. Glue is the key factor in bonding the cardboard and the corrugated core together.

[0004] In the existing technical solutions, corrugated paper is an important component of the carton. Choosing high-strength corrugated paper can effectively improve the compressive strength of the carton. Most of the time, multi-layer corrugated paperboard is used to increase the load-bearing capacity of the carton. Although multi-layer corrugated paperboard increases the load-bearing capacity of the carton, the strength of the carton may still be insufficient for particularly heavy goods or scenarios that require long-term load-bearing. Summary of the invention

[0005] The purpose of the present invention is to provide a high-strength corrugated paper box, in which the support plate, support ring and load-bearing frame can enhance the supporting force of the bottom, sides and top of the paper box, making it more stable when facing external pressure. The design of this enhanced structure enables the paper box to withstand greater vertical pressure, and effectively prevents the paper box from being deformed or damaged due to pressure during transportation and storage; by enhancing the structural strength of the paper box, the support plate can better protect the items in the package from external impact and extrusion, so as to solve the problems raised in the above-mentioned background technology.

[0007] A protective support assembly is arranged on the inner side of the corrugated paperboard assembly, and the protective support assembly comprises a support plate fixedly mounted around the upper end of the corrugated paper box base, and the structure of the support plate is an X-shaped structure.

[0008] Preferably, an inner paperboard is fixedly mounted on one end of the corrugated core away from the outer paperboard, and the interior of the supporting bag strip is filled with lime desiccant.

[0009] Preferably, a first inner lining corrugated board and a second inner lining corrugated board are arranged on the inner side of the corrugated board assembly, and an assembly partition is formed between the corrugated board assembly and the first inner lining corrugated board and the second inner lining corrugated board.

[0010] Preferably, the first lining corrugated board and the second lining corrugated board are perpendicular to each other, the first lining corrugated board and the second lining corrugated board are movably fitted together, and the first lining corrugated board, the second lining corrugated board and the corrugated box base are movably fitted together.

[0011] Preferably, the protective support assembly further comprises an assembly groove provided inside the support plate, and a buffer top plate is slidably mounted inside the inner side of the assembly groove.

[0012] Preferably, a push plate is slidably mounted on the inner and outer sides of the assembly groove, and a limiting strip is fixed on the outer side of the assembly groove.

[0013] Preferably, a pointed cone is fixedly mounted on the outer side of the push plate, and a spring is fixedly mounted on the inner side of the push plate. There are a plurality of pointed cones, and the pointed cones correspond to the supporting bladder strips.

[0014] Preferably, buffer capsules are fixedly installed around the intersection of the support plates, and there are four buffer capsules. The inner end surfaces of the buffer capsules are in contact with the first inner lining corrugated board and the second inner lining corrugated board, and the outer end surfaces of the buffer capsules are in contact with the inner paperboard.

[0015] Preferably, a one-way exhaust valve tube is fixedly installed at the joint between the support plate and the buffer bag, and the buffer bag is connected with the inside of the assembly groove through the one-way exhaust valve tube. A one-way intake valve tube is fixedly installed at the middle position of the support plate, and the one-way intake valve tube is connected with the inside of the assembly groove.

[0016] Preferably, the outer sleeve of the corrugated box cover is provided with a support ring, the four corners of the bottom end of the support ring abut against the top end of the support plate, and the four corners of adjacent support plates abut against each other.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The support plate of the protective support assembly of the present invention can cooperate with the support ring and the load-bearing frame to ensure the overall strength of the corrugated paper box. The support plate, the support ring and the load-bearing frame can enhance the supporting force of the bottom, sides and top of the paper box, making it more stable when facing external pressure. The design of this enhanced structure enables the paper box to withstand greater vertical pressure, and effectively prevents the paper box from being deformed or damaged due to pressure during transportation and storage; by enhancing the structural strength of the paper box, the support plate can better protect the items in the package from external impact and extrusion, which is particularly important for transporting valuables, fragile items or goods that require special protection.

[0019] 2. The present invention inserts and fills support bag strips in the corrugated core. The addition of the support bag strips can further enhance the structural strength of the corrugated paper box, making it more stable when subjected to external forces. This structure can make the corrugated paper board more evenly distributed when subjected to external forces, avoiding damage caused by excessive local forces. The support bag strips can fill the gaps in the corrugated core, increase the overall rigidity of the carton, and prevent the carton from deforming due to uneven forces during transportation and storage. This improvement in structural stability helps to maintain the shape and size of the carton, ensuring that the items in the package will not be damaged due to deformation of the carton.

[0020] 3. The supporting bag strips of the present invention can expose the lime desiccant filled inside, so that the moisture around the carton can be absorbed by the lime desiccant. The lime desiccant has a strong moisture absorption capacity and can quickly absorb the moisture around the carton to reduce the humidity of the carton and the items inside. The poor waterproof and moisture-proof properties of corrugated carton have always been its defect. The arrangement of lime desiccant inside the carton can make up for this defect to a certain extent. By absorbing moisture, the lime desiccant helps to keep the carton in a dry state, thereby improving the strength and stability of the carton and preventing the carton from being deformed or damaged due to moisture.

[0021] 4. The present invention can provide a buffering and protective effect on the internal items through the inflation of the buffer bag in conjunction with the first inner lining corrugated board and the second inner lining corrugated board. The inflation of the buffer bag can absorb and disperse external impact forces, reduce the impact and vibration of the items during transportation, and in conjunction with the first inner lining corrugated board and the second inner lining corrugated board, a multi-level buffer system can be formed to further improve the buffering effect.

[0022] 5. The carton provided in the present invention can be composed of a three-layer structure of a corrugated cardboard component, a protective support component and an inner lining corrugated board. This can avoid the problem of local bulging of the carton during assembly. The three-layer structure design effectively reduces the local bulging phenomenon caused by external force extrusion or uneven internal stress by increasing the layering and supporting force of the carton.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention provides a technical solution:

[0036] See also Figures 1 to 4 A high-strength corrugated paper box, comprising a corrugated paper box base 7, the bottom end of the corrugated paper box base 7 is fixedly connected with a carrier frame 2, a corrugated paper board assembly 1 is arranged at the four peripheral edges of the corrugated paper box base 7, a corrugated paper board cover 3 is detachably installed on the upper end of the corrugated paper board assembly 1, the corrugated paper board assembly 1 comprises an outer paper board 101 fixed at the four peripheral edges of the corrugated paper box base 7, a corrugated core 102 is fixedly installed on the inner side wall of the outer paper board 101, a supporting bag strip 104 is fixedly installed inside the corrugated core 102, and an inner paper board 103 is fixedly installed at one end of the corrugated core 102 away from the outer paper board 101;

[0037] A protective support assembly 6 is provided on the inner side of the corrugated cardboard assembly 1, and the protective support assembly 6 includes a support plate 601 fixedly installed around the upper end of the corrugated box base 7. The structure of the support plate 601 is an X-shaped structure. A first lining corrugated board 5 and a second lining corrugated board 8 are provided on the inner side of the corrugated cardboard assembly 1. An assembly interlayer 4 is formed between the corrugated cardboard assembly 1 and the first lining corrugated board 5 and the second lining corrugated board 8. The first lining corrugated board 5 and the second lining corrugated board 8 are perpendicular to each other, and the first lining corrugated board 5 and the second lining corrugated board 8 are movably fitted. The first lining corrugated board 5, the second lining corrugated board 8 and the corrugated box base 7 are movably fitted. The outer sleeve of the corrugated box cover 3 is provided with a support ring 9, and the four corners of the bottom end of the support ring 9 are in contact with the top end of the support plate 601, and the four corners of adjacent support plates 601 are in contact with each other.

[0038] By adopting the above technical solution, when in use, the support ring 9 is fixedly sleeved on the outside of the corrugated box cover 3 to enhance the strength of the corrugated box cover 3. When the corrugated box cover 3 and the corrugated board assembly 1 are assembled and disassembled, they can be disassembled and connected by stapling. The outer board 101, the inner board 103 and the corrugated core 102 are fixedly connected by gluing. At the same time, the support bag strip 104 is inserted and filled in the corrugated core 102. The addition of the support bag strip 104 can further enhance the structural strength of the corrugated box, making it more stable when subjected to external force; this structure can make the corrugated board more evenly distributed when subjected to external force, avoiding damage caused by excessive local force; the support bag strip 104 can fill the gap in the corrugated core 102, increase the overall rigidity of the carton, and prevent the carton from being deformed due to uneven force during transportation and storage; the improvement of this structural stability helps to maintain the shape and size of the carton, ensuring that the items in the package will not be damaged due to deformation of the carton. It should be noted that the protective support assembly 6 is assembled in the assembly compartment 4, and the support plate 601 of the protective support assembly 6 can cooperate with the support ring 9 and the carrier frame 2 to ensure the overall strength of the corrugated box. The support plate 601, the support ring 9 and the carrier frame 2 can enhance the supporting force of the bottom, sides and top of the box, making it more stable when facing external pressure. The design of this enhanced structure enables the box to withstand greater vertical pressure and effectively prevents the box from being deformed or damaged due to pressure during transportation and storage. By enhancing the structural strength of the box, the support plate 601 can better protect the items in the package from external impact and extrusion, which is especially important for transporting valuables, fragile items or goods that require special protection.

[0039] Specifically, Figures 4 to 7 As shown, the interior of the supporting bag strip 104 is filled with lime desiccant 105, and the protective support assembly 6 also includes an assembly groove 606 opened in the support plate 601, a buffer top plate 607 is slidably installed on the inner side of the assembly groove 606, a push plate 603 is slidably installed on the inner outer side of the assembly groove 606, a limiting strip 605 is fixed on the outer side of the assembly groove 606, a pointed cone 604 is fixedly installed on the outer side of the push plate 603, and a spring 610 is fixedly installed on the inner side of the push plate 603, and a plurality of pointed cones 604 are provided, and the pointed cones 604 correspond to the supporting bag strip 104.

[0040] By adopting the above technical solution, when in use, the moisture-proof adjustment is controlled according to the use requirements of the carton. When moisture-proofing is required, the carton is filled with items, so that the first inner lining corrugated board 5 and the second inner lining corrugated board 8 can be squeezed by the pressure of the items. The first inner lining corrugated board 5 and the second inner lining corrugated board 8 can be further squeezed by being squeezed. After the buffer top plate 607 is squeezed, the buffer top plate 607 can slide inside the assembly groove 606 of the support plate 601, so that the air inside the assembly groove 606 can be squeezed. When the buffer top plate 607 is squeezed, the spring 610 can be squeezed, and the spring 610 can push the push plate 603 to move in the assembly groove 606. The movement of the push plate 603 can further push the pointed cone 604 to move. When the pointed cone 604 moves, the pointed cone 604 can pierce the inner cardboard 103, so that the support bag strip 104 on the side of the inner cardboard 103 can be squeezed. The support bag strip 104 can be exposed by the pointed cone 604. It should be noted that the inner cardboard 103 and the support bag strip 104 cannot be pierced only by the force of the spring 610. The buffer top plate 607 and the spring 610 need to cooperate with each other to achieve the piercing of the support bag strip 104. In this way, the moisture around the carton can be absorbed by the lime desiccant 105. The lime desiccant 105 has a strong moisture absorption capacity and can quickly absorb the moisture around the carton to reduce the humidity of the carton and the internal items. The poor waterproof and moisture resistance of corrugated carton has always been its defect. The lime desiccant 105 is arranged inside the carton to make up for this defect to a certain extent. By absorbing moisture, the lime desiccant 105 helps to keep the carton dry, thereby improving the strength and stability of the carton and preventing the carton from being deformed or damaged due to moisture.

[0041] Specifically, Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, buffer capsules 602 are fixedly installed around the intersection of the support plate 601, and the number of the buffer capsules 602 is four. The inner end surfaces of the buffer capsules 602 are in contact with the first inner lining corrugated board 5 and the second inner lining corrugated board 8, and the outer end surfaces of the buffer capsules 602 are in contact with the inner paperboard 103. A one-way exhaust valve tube 609 is fixedly installed at the contact point between the support plate 601 and the buffer capsule 602, and the buffer capsule 602 is communicated with the inside of the assembly groove 606 through the one-way exhaust valve tube 609. A one-way air intake valve tube 608 is fixedly installed at the middle position of the support plate 601, and the one-way air intake valve tube 608 is communicated with the inside of the assembly groove 606.

[0042] By adopting the above technical solution, when in use, when the buffer top plate 607 slides inside the assembly groove 606 of the support plate 601, the air inside the assembly groove 606 can be squeezed, and the air inside the assembly groove 606 can enter the buffer bag 602 through the one-way exhaust valve pipe 609, so that the inside of the buffer bag 602 can be inflated, and the inflation expansion of the buffer bag 602 and the cooperation of the first inner lining corrugated board 5 and the second inner lining corrugated board 8 can play a buffering and protective effect on the internal items. The inflation expansion of the buffer bag 602 It can absorb and disperse external impact forces, reduce the impact and vibration of articles during transportation, and cooperate with the first lining corrugated board 5 and the second lining corrugated board 8 to form a multi-level buffer system to further improve the buffering effect; by enhancing the buffering performance, this setting can also extend the service life of the carton, so that it can withstand more handling and transportation processes without being easily damaged. The cooperation between the buffer bag 602 and the lining corrugated board can more effectively utilize the internal space of the carton, reduce gaps and shaking, and thus improve the stability and efficiency of packaging. When the buffer top plate 607 is not squeezed, the buffer top plate 607 can be lifted up under the elastic force of the spring 610, so that the one-way air intake valve pipe 608 can absorb the outside air and introduce the outside air into the assembly groove 606. It should be noted that the connection between the buffer top plate 607 and the support plate 601 is in contact with each other to ensure the sealing effect of the buffer top plate 607 when moving, so as to avoid the problem of air leakage. The front, back, left and right sides of the carton can be composed of the corrugated cardboard component 1, the protective support component 6 The three-layer structure with the inner lining corrugated board can avoid the problem of local bulging in the carton during assembly. The three-layer structure design effectively reduces the local bulging caused by external force extrusion or uneven internal stress by increasing the layering and supporting force of the carton. The three-layer structure design makes the carton more stable in the overall structure and can withstand greater external force and pressure. The corrugated board component 1 serves as the outer layer, providing basic strength and rigidity; the protective support component 6 serves as the middle layer, playing a role of reinforcement and support; the inner lining corrugated board serves as the inner layer to protect the items and prevent internal damage.

[0043] Working principle: When in use, the support ring 9 is fixedly sleeved on the outside of the corrugated box cover 3 to enhance the strength of the corrugated box cover 3. When the corrugated box cover 3 and the corrugated board component 1 are assembled and disassembled, they can be disassembled and connected by stapling. The outer cardboard 101, the inner cardboard 103 and the corrugated core 102 are fixedly connected by gluing. At the same time, the support bag strip 104 is inserted and filled in the corrugated core 102, and the protective support component 6 is assembled in the assembly interlayer 4. The support plate 601 of the protective support component 6 can cooperate with the support ring 9 and the carrier frame 2 to ensure the overall strength of the corrugated box. The support plate 601, the support ring 9 and the carrier frame 2 can enhance the supporting force of the bottom, side and top of the carton. When moisture-proofing is required, the first inner lining corrugated board 5 and the second inner lining corrugated board 8 can be squeezed by the items filled in the carton. The first inner lining corrugated board 5 and the second inner lining corrugated board 8 are squeezed, which can further squeeze the buffer top plate 607. After the buffer top plate 607 is squeezed, the buffer top plate 607 can slide inside the assembly groove 606 of the support plate 601, so that the air inside the assembly groove 606 can be squeezed. When the buffer top plate 607 is squeezed, the spring 610 can be squeezed, and the spring 610 can push the push plate 603 to move in the assembly groove 606. The movement of the push plate 603 can further push the pointed cone 604 to move. When the pointed cone 604 moves, the pointed cone 604 can pierce the inner paperboard 103, so that the support bag strip 104 on the side of the inner paperboard 103 can be squeezed, so that the pointed cone 604 can pierce the support bag strip 104, and the support bag strip 104 can expose the lime desiccant 105 filled inside, so that the moisture around the carton can be absorbed by the lime desiccant 105.

[0044] When in use, when the buffer top plate 607 slides inside the assembly groove 606 of the support plate 601, the air inside the assembly groove 606 can be squeezed, and the air inside the assembly groove 606 can enter the buffer bag 602 through the one-way exhaust valve tube 609, so that the inside of the buffer bag 602 can be inflated, and the inflation expansion of the buffer bag 602 and the cooperation of the first inner lining corrugated board 5 and the second inner lining corrugated board 8 can play a buffering and protective effect on the internal items; when the buffer top plate 607 is not squeezed, the buffer top plate 607 can be lifted up under the elastic force recovery of the spring 610, so that the one-way air intake valve tube 608 can absorb the outside air, and the one-way air intake valve tube 608 introduces the outside air into the assembly groove 606. It should be noted here that the connection between the buffer top plate 607 and the support plate 601 fits each other, so as to ensure the sealing effect of the buffer top plate 607 when moving and avoid the problem of air leakage.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
