The outside also has a certain waterproof effect, which avoids the invasion of external rainwater, thereby effectively protecting the items inside. At the same time, under the action of internal elastic support, it can also appropriately deflect when the internal items are under pressure, so that the pressure is not easily applied to the surface of the items, which has a buffering and protective effect on the packaged and transported items, and can better ensure the safety of the goods.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] See also Figures 1 to 3 The present application provides a technical solution: a packaging carton, comprising a carton base layer 1, with a protective component 200 installed between the outer side and the inner side of the carton base layer 1 for protecting it; through the use of the protective component 200 on the outer side of the carton base layer 1, the pressure-bearing capacity and actual protective effect of the packaging carton can be further enhanced, so that it has excellent load-bearing capacity and can be suitable for long-term stacking requirements, and the outer side also has a certain waterproof effect, avoiding the invasion of external rainwater, thereby effectively protecting the internal items. At the same time, under the action of internal elastic support, it can also appropriately deflect when the internal items are under pressure, so that the pressure is not easily applied to the surface of the items, which has a buffering protection effect on the packaged and transported items and can better ensure the safety of the goods.

[0031] In this embodiment, the protection component 200 is a structure for effectively protecting the goods on the outside and inside of the carton.

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, the protective component 200 includes an inner layer 201 bonded to the inner side of the carton base layer 1, a wear-resistant layer 202 bonded to the outer side of the carton base layer 1, an elastic support layer 203 bonded to the inner bottom wall of the inner layer 201, a plurality of reinforcing ribs 204 fixed between the top of the elastic support layer 203 and the inner top wall of the inner layer 201, four corner guards 205 fixed to the outer side of the wear-resistant layer 202, and two waterproof layers 206 respectively coated on the outer side of the wear-resistant layer 202 and the inner side of the inner layer 201.

[0033] It should be noted that the carton base layer 1 is a box structure with an openable and closable top. The outer side of the elastic support layer 203 is fixedly connected to the inner side of the inner layer 201. The elastic support layer 203 includes a rubber shell 2031, a spring 2032, a rubber column 2033 and a rubber airbag 2034. The rubber shell 2031 is bonded to the inner side of the inner layer 201 and is fixedly connected to the inner bottom wall of the inner layer 201. The springs 2032 are distributed in a dotted manner on the inner side of the rubber shell 2031. The number of springs 2032 is equal to the number of rubber columns 2033. The top and bottom of the springs 2032 and the rubber columns 2033 are fixedly connected to the inner top wall and the inner bottom wall of the rubber shell 2031 respectively. The springs 2032 are located on the outer sides of the corresponding rubber columns 2033. The rubber airbags 2034 are distributed in a dotted manner. The rubber airbag 2034 is distributed on the inner side of the rubber shell 2031, and the top and bottom of the rubber airbag 2034 are fixedly connected to the inner top wall and the inner bottom wall of the rubber shell 2031 respectively. The rubber airbag 2034 and the spring 2032 are staggered, so that the spring 2032 can be stably compressed under the action of the corresponding rubber column 2033, and under the deformation action of the rubber column 2033, the reciprocating rebound elastic force of the spring 2032 can be absorbed to a certain extent, so that the spring 2032 is not prone to reciprocating rebound, and the rubber column 2033 can play the damping effect of the damper, and under the deformation action of the rubber airbag 2034, it can cooperate with the spring 2032 to absorb the pressure and store energy, so that the goods placed on the top can obtain a stable and effective elastic support effect.

[0034] In addition, the inner layer 201 is a kraft paper layer. Kraft paper has high strength, tear resistance, rupture work and dynamic strength, and can be used as a packaging material. It itself has certain waterproof and wear-resistant properties, so that it can provide excellent protection for the inside of the carton. The reinforcement ribs 204 are high-strength polypropylene rods, and several reinforcement ribs 204 are symmetrically distributed on the left and right. Polypropylene has excellent mechanical properties, including tensile strength, compressive strength and hardness, outstanding rigidity and bending fatigue resistance, and good heat resistance. It also has strong chemical stability. Except for strong oxidants, it does not react with most chemicals, so that it can provide stable and effective support for the carton.

[0035] In addition, the wear-resistant layer 202 is a honeycomb cardboard layer, which has excellent wear resistance and load-bearing capacity, so that the overall pressure-bearing capacity and load-bearing capacity of the carton can be further enhanced. The waterproof layer 206 is a polyurethane coating. The polyurethane coating has excellent water resistance and can effectively resist the corrosion of chemicals. It also has the characteristics of wear resistance, high temperature resistance, oxidation resistance and UV resistance, and can effectively protect the outside of the carton. The carton base layer 1 is made of three layers of high-strength corrugated paper bonded together, which gives it extremely strong pressure resistance and load-bearing strength, so that the carton as a whole can stably supply goods for packaging and transportation. Among them, when the goods are packaged and transported, the overall shape of the carton needs to be matched and customized with the size of the goods, and the bottom of the goods also needs to abut against the foam box that is adapted to the outside of the bottom of the goods, and be connected to the foam box through connectors such as cable ties to avoid direct contact between the goods and the inner wall of the carton, thereby further protecting the safety of the goods.

[0036] The working principle of the above embodiment is:

[0037] When packaging and transporting goods, the goods are placed inside the carton and on top of the elastic support layer 203. The reinforcing ribs 204 can greatly increase the pressure-bearing capacity of the carton, so that it can be stacked stably for a long time. Under the elastic support of the elastic support layer 203, even after the top of the carton is compressed and deformed, the pressure applied to the top of the goods will squeeze the goods downward, causing the spring 2032, rubber column 2033 and rubber airbag 2034 inside the elastic support layer 203 to further deform, so as to meet the elastic deformation when the pressure arrives, and avoid the pressure being directly applied to the top of the goods as much as possible, thereby effectively protecting the goods. Under the action of the waterproof layer 206, it can also play a certain waterproof effect, which can prevent the internal structure from being eroded. Under the action of the corner protector 205, the corners of the carton can be protected to avoid large deformation due to impact, so that the goods can be transported safely and stably.

[0038] Compared with the existing technology, this packaging carton, through the use of the protective component 200 on the outside of the carton base layer 1, can further enhance the pressure-bearing capacity and actual protective effect of the packaging carton, so that it has excellent load-bearing capacity and can be suitable for long-term stacking needs. The outside also has a certain waterproof effect, which avoids the invasion of external rainwater, thereby effectively protecting the internal items. At the same time, under the action of internal elastic support, it can also appropriately deflect when the internal items are under pressure, so that the pressure is not easily applied to the surface of the items, which has a buffering and protective effect on the packaged and transported items, can better ensure the safety of the goods, and solves the shortcomings of existing packaging cartons that are easily deformed by external pressure when stacked, thereby causing damage to the internal items.
