Description

Technical Field

[0001] This invention belongs to the field of corrugated cardboard box technology, specifically relating to a green, environmentally friendly, biodegradable, and antibacterial corrugated cardboard box. Background Technology

[0002] Corrugated cardboard boxes, as lightweight, low-cost, and easy-to-process packaging containers, are widely used in commodity transportation and storage, and are an indispensable part of the modern logistics packaging system. However, with the increasing global awareness of environmental protection and the advancement of "dual carbon" goals, the environmental shortcomings of traditional corrugated cardboard boxes are becoming increasingly prominent. Traditional corrugated cardboard boxes often use non-degradable plastic accessories (such as waterproof tape and plastic cushioning pads) and non-environmentally friendly adhesives, making them difficult to degrade naturally after disposal, easily causing white pollution and damage to soil and water environments. At the same time, the structural design of traditional corrugated cardboard boxes is relatively simple, mostly single-layer or double-layer corrugated structures, which can only achieve basic load-bearing and protective functions, lacking antibacterial properties. When packaging food, medicine, and other products susceptible to microbial contamination, bacteria, mold, and other microorganisms easily grow on the inner walls of the boxes, leading to spoilage and damage of the packaged products, affecting product quality and safety. Therefore, there is an urgent need for a green, environmentally friendly, biodegradable, and antibacterial corrugated cardboard box to solve the above problems. Summary of the Invention

[0003] In view of the problems raised in the background art above, the purpose of this invention is to provide a green, environmentally friendly, biodegradable, antibacterial corrugated cardboard box.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: An environmentally friendly, biodegradable, antibacterial corrugated cardboard box includes a box body, which is a rectangular hollow structure. A base is installed at the bottom of the box body, and a cover is installed at the top of the box body. An antibacterial component is installed on the bottom inner side of the cover. The box body includes an outer layer of biodegradable face paperboard, a middle corrugated core paperboard, and an inner layer of antibacterial biodegradable liner paper. The middle corrugated core paperboard has a number of honeycomb holes, and biodegradable cushioning cotton is filled in the honeycomb holes.

[0005] Furthermore, the outer biodegradable paperboard is made of a blend of corn fiber and bamboo fiber, and its surface is coated with a biodegradable plant wax coating. The inner antibacterial biodegradable linerboard is made of biodegradable paper loaded with a nano-zinc oxide antibacterial agent. This structural design provides both protection and environmental friendliness, as well as load-bearing capacity.

[0006] Furthermore, the box body has reinforcing ribs on all four internal sides, the ribs being arranged in an isosceles triangular structure and evenly distributed along the height of the box body. The four corners of the box body surface are also rounded. This structural design improves the box body's resistance to pressure and deformation.

[0007] Further specifying, the base is equipped with a supporting keel, which includes several longitudinal and transverse supporting ribs. The longitudinal supporting ribs are arranged along the length of the base, and the transverse supporting ribs are arranged along the width of the base. The longitudinal and transverse supporting ribs are arranged perpendicularly to each other. Both the base and the supporting keel are made of biodegradable pulp through molding. The bottom of the base has several evenly distributed anti-slip protrusions. The base is spliced ​​and fixed to the bottom of the box body using biodegradable adhesive. This structural design improves the load-bearing capacity and stability of the base, preventing the box body from tilting due to uneven force on the bottom.

[0008] Furthermore, the cover plate has wrapping edges on all four sides, and a biodegradable sealing gasket is provided on the bottom inner side of the cover plate. The bottom of the biodegradable sealing gasket fits tightly against the top edge of the box. This structural design achieves a seal on the top of the box, effectively preventing dust, moisture, and microorganisms from entering.

[0009] Furthermore, the antibacterial component includes an antibacterial box, the top of which is attached to the bottom of a cover plate with a biodegradable adhesive. Antibacterial particles are placed inside the antibacterial box, and several evenly arranged ventilation holes are provided on its four sides. This structural design provides an antibacterial effect inside the box.

[0010] Furthermore, the antibacterial particles are made from a mixture of chitosan and plant extracts. The antibacterial box is covered with an antibacterial breathable membrane on the outside of the vents. The antibacterial breathable membrane is adhered and fixed to the side wall of the antibacterial box. The antibacterial breathable membrane is made of biodegradable non-woven fabric. This structural design prevents the antibacterial particles from scattering while ensuring the normal diffusion of antibacterial agents.

[0011] Furthermore, the interior of the enclosure is equipped with sidewall buffer layers on all four sides, and these sidewall buffer layers are arranged in a wave-like structure. This structural design can effectively absorb external impacts and achieve a cushioning effect.

[0012] Furthermore, the top two sides of the box are provided with gripping grooves. This structural design makes operation simple and labor-saving, improving handling efficiency.

[0013] Furthermore, the top of the base is covered with a sponge pad, which is located on the inner bottom of the housing. This structural design can effectively absorb the impact force generated by vibration and impact.

[0014] The beneficial effects of this invention are as follows: This invention utilizes a dual antibacterial structure of an inner antibacterial liner and an antibacterial box to effectively inhibit the growth and reproduction of bacteria, mold, and other microorganisms inside the box. The antibacterial effect is stable and has a high inhibition rate against common pathogens. It can meet the needs of food, pharmaceutical, and fresh food industries that have high requirements for packaging antibacterial properties, and prevent the contents from deteriorating or being damaged due to microbial contamination.

[0015] This invention significantly improves the load-bearing strength and deformation resistance of the box by setting an intermediate corrugated core cardboard, reinforcing ribs and supporting keel. The combination of honeycomb corrugated structure and cushioning cotton ensures both biodegradability and load-bearing stability, which can meet the needs of stacked transportation and reduce the damage rate during transportation.

[0016] All components of this invention are made of green, environmentally friendly, and biodegradable materials, and are joined together using biodegradable adhesives. There are no non-biodegradable accessories. After disposal, it can quickly and naturally degrade without causing white pollution, meeting environmental protection requirements and the "dual carbon" target. This achieves greening of the entire life cycle of the packaging. At the same time, it can be recycled and degraded as a whole after disassembly, improving resource utilization.

[0018] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, a green, environmentally friendly, biodegradable, antibacterial corrugated cardboard box has a rectangular hollow structure 1. A base 2 is installed at the bottom of the box 1, and a cover 3 is installed at the top of the box 1. An antibacterial component 4 is installed on the bottom inner side of the cover 3. The box body 1 includes an outer layer of biodegradable face paper 5, a middle corrugated core paper 6 and an inner layer of antibacterial biodegradable liner paper 7. The middle corrugated core paper 6 has several honeycomb holes 8, and the honeycomb holes 8 are filled with biodegradable cushioning cotton 9.

[0020] In this embodiment, the box 1 adopts a three-layer composite cardboard structure. The outer layer of biodegradable cardboard 5 provides basic scratch and wear resistance protection. The honeycomb holes 8 of the middle corrugated core cardboard 6 are filled with polylactic acid biodegradable cushioning cotton 9. When the box is subjected to external impact or compression, the porous structure of the honeycomb holes can first disperse the impact force, and the cushioning cotton absorbs the remaining energy through its own deformation to achieve cushioning and prevent the contents from making hard contact with the box. The inner layer of antibacterial biodegradable liner paper 7, together with antibacterial components 4, continuously releases antibacterial factors to inhibit the growth of microorganisms in the box 1, forming a dual protection of space antibacterial and surface antibacterial.

[0021] All components of this cardboard box are made of biodegradable materials. After disposal, it can biodegrade in the natural soil environment, leaving no white pollution residue, and complies with the national green logistics packaging policy and sustainable development requirements.

[0022] Example 2, as Figure 2 and Figure 5 As shown, this embodiment adds the following structure to the basis of embodiment 1: the outer biodegradable paperboard 5 is made of a mixture of corn fiber and bamboo fiber, the surface of the outer biodegradable paperboard 5 is coated with a biodegradable plant wax coating, and the inner antibacterial biodegradable liner paper 7 is made of biodegradable paper loaded with nano zinc oxide antibacterial agent.

[0023] In this embodiment, the outer biodegradable faceboard 5 is prepared by mixing corn fiber and bamboo fiber. Both natural fibers have good biodegradability and can be decomposed into harmless substances by microorganisms in the natural environment. The biodegradable plant wax coating applied to the surface can form a dense protective film on the faceboard surface, blocking external moisture and dust from entering, while not affecting the overall biodegradability. The inner antibacterial biodegradable linerboard 7 loads nano zinc oxide antibacterial agent into the biodegradable paper material. Utilizing the antibacterial properties of nano zinc oxide, it destroys the cell membrane structure of bacteria, mold and other microorganisms in the box, inhibits their reproduction, and achieves antibacterial protection inside the box. Moreover, the nano zinc oxide is tightly bonded to the biodegradable paper material and will not fall off, and can degrade together with the paper material.

[0024] Example 3, as Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: the four sides of the interior of the box 1 are provided with reinforcing ribs 10, the reinforcing ribs 10 are arranged in an isosceles triangle structure, the reinforcing ribs 10 are evenly distributed along the height direction of the box 1, and the four corners of the surface of the box 1 are provided with arc-shaped rounded corners 11.

[0025] In this embodiment, by installing isosceles triangular reinforcing ribs 10 on the four sides inside the box 1, the pressure on the side wall of the box 1 is dispersed, preventing the box 1 from collapsing or deforming when loaded with heavy objects or subjected to external pressure, thus improving the overall pressure resistance of the box. The four corners of the box 1 are provided with arc-shaped rounded corners, changing the sharp structure at the corners into arcs, reducing stress concentration at the corners, preventing the corners from being damaged due to excessive force during handling and stacking, and reducing the risk of scratches during handling.

[0026] Example 4, as Figure 2 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the base 2 is provided with a supporting keel 12, which includes several longitudinal supporting ribs 13 and transverse supporting ribs 14. The several longitudinal supporting ribs 13 are arranged along the length direction of the base 2, and the several transverse supporting ribs 14 are arranged along the width direction of the base 2. The longitudinal supporting ribs 13 and the transverse supporting ribs 14 are arranged perpendicularly to each other. The base 2 and the supporting keel 12 are both made of biodegradable pulp molding. The bottom of the base 2 is provided with several evenly distributed anti-slip protrusions 15. The base 2 is spliced ​​and fixed to the bottom of the box 1 by biodegradable adhesive.

[0027] In this embodiment, the supporting keel 12 inside the base 2 is arranged with longitudinal supporting ribs 13 and transverse supporting ribs 14 perpendicularly intersecting each other to form a mesh structure. By utilizing the synergistic effect of cross support, the weight of the box 1 and the contents inside is distributed, and the pressure is evenly transmitted to various parts of the base 2, so as to avoid the base 2 from being deformed or damaged due to excessive local stress. Moreover, the base 2 and the supporting keel are made of biodegradable pulp molding, which takes into account both biodegradability and structural strength, and can be degraded along with the whole carton. The anti-slip protrusions at the bottom of the base 2 increase the friction between the base 2 and the placement surface, preventing the carton from sliding during handling and stacking.

[0028] Example 5, as Figure 1 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 1: the four sides of the cover plate 3 are provided with wrapping edges 16, and the bottom of the inner side of the cover plate 3 is provided with a biodegradable sealing gasket 17. The bottom of the biodegradable sealing gasket 17 is tightly fitted with the top edge of the box body 1.

[0029] In this embodiment, the wrapping edges 16 on the four sides of the cover plate 3 can wrap around the four sides of the top of the box 1 when the cover plate 3 is installed on the top of the box 1, preventing the cover plate 3 from shifting. The biodegradable sealing gasket 17 on the inner side of the cover plate 3 fits tightly with the top edge of the box 1 to form a sealing structure, blocking external dust, moisture and microorganisms from entering the box.

[0030] Example 6, as Figure 2 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 1: the antibacterial component 4 includes an antibacterial box 18, the top of the antibacterial box 18 is installed on the bottom of the cover plate 3 by a biodegradable adhesive, antibacterial particles 19 are placed inside the antibacterial box 18, and several evenly arranged venting holes 20 are opened on the four sides of the antibacterial box 18.

[0031] In this embodiment, the antibacterial component 4 is fixed to the bottom of the cover plate 3 by a biodegradable adhesive. After the cover plate 3 is closed, it enters the box 1 together. During use, the antibacterial particles 19 in the antibacterial box 18 continuously release antibacterial factors. The antibacterial factors diffuse into the box 1 through the ventilation holes 20 on the four sides of the antibacterial box 18, come into contact with bacteria, mold and other microorganisms in the box 1, inhibit their growth and reproduction, and achieve antibacterial protection.

[0032] Example 7, as Figure 2 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 6: the antibacterial particles 19 are made of a mixture of chitosan and plant extracts, the antibacterial box 18 is covered with an antibacterial breathable membrane on the outside of the vent 20, the antibacterial breathable membrane is bonded and fixed to the side wall of the antibacterial box 18, and the antibacterial breathable membrane is made of biodegradable non-woven fabric.

[0033] In this embodiment, the antibacterial particles 19 are made of a mixture of chitosan and plant extracts. Chitosan itself has good antibacterial properties and can destroy the cell membrane of microorganisms. Plant extracts (such as mugwort and honeysuckle extracts) can help enhance the antibacterial effect. At the same time, both are natural materials that can be naturally degraded and have no harmful residues. The antibacterial breathable membrane set on the outside of the vent 20 of the antibacterial box 18 allows antibacterial factors to diffuse into the box 1 through the vent 20, and also prevents the antibacterial particles 19 from falling out of the vent 20 due to vibration or handling.

[0034] Example 8, as Figure 2 and Figure 5 As shown, this embodiment adds the following structure to the embodiment 1: the four sides of the inside of the box 1 are equipped with side wall buffer layers 21, and the side wall buffer layers 21 are arranged in a wave-shaped structure.

[0035] In this embodiment, when the box 1 is subjected to external impact or compression, the side wall buffer layer 21 can deform to absorb the impact force, buffer and disperse the external force, and reduce the effect of the external force on the items inside the box.

[0036] Example 9, as Figure 1 As shown, this embodiment adds the following structure to the embodiment 1: grip grooves 22 are provided on both sides of the top of the box 1.

[0037] In this embodiment, during the handling process, the grip grooves 22 on both sides of the top of the box 1 provide convenient gripping points for the operator. The operator can easily lift and move the carton through the grip grooves 22 without the need for additional tools.

[0038] Example 10, as Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: a sponge pad 23 is laid on the top of the base 2, and the sponge pad 23 is set on the bottom inner side of the box 1.

[0039] In this embodiment, when the box 1 is subjected to vibration or bumps, the sponge pad 23 can absorb the impact force through its own compression deformation, reduce the collision between the item and the base, and avoid damage to the bottom of the item.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
