The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or selectively mutually exclusive embodiment with other embodiments.

[0031] Embodiment

[0032] Referring to Figures 1 to 7 , it is an embodiment of the present utility model. This embodiment provides a shock-absorbing and buffering packaging carton. As Figures 1 - 5 shown, the box body assembly 100 includes a side cardboard 101 and a top cover cardboard 102. The side cardboard 101 and the top cover cardboard 102 are made of one cardboard. The side cardboard 101 is folded to form a carton with a volume for loading goods. The shape of the volume depends on the shape of the item. The cardboard also has a sandwich structure and has a certain role in buffering and shock absorption to protect the item. The top cover cardboard 102 is used to block the top of the carton volume. A bundling depression 101a is provided on the outer surface of the side cardboard 101. According to the shape of the item, the provided bundling depression 101a can quickly bundle the item at an accurate position and can also avoid bundling the vulnerable parts of the item to prevent the item from being damaged;

[0033] As Figures 1 - 2 shown, a clamping edge 102a and a sealing edge 102a-1 are provided at the edge of the top cover cardboard 102. The clamping edge 102a and the sealing edge 102a-1 at the edge of the top cover cardboard 102 are engaged and clamped with the encapsulation clamping board 201a. While the folded encapsulation clamping board 201a is tightly clamped with the clamping edge 102a and the sealing edge 102a-1, it also acts as a cushion layer to protect the top of the item. The encapsulation clamping board 201a is arranged on the buffer cardboard 201 and is used for finally sealing the top of the carton.

[0034] The buffer assembly 200 is arranged inside the volume of the carton.

[0035] As Figure 6As shown, the buffer component 200 includes a buffer cardboard 201. The buffer cardboard 201 is folded and cooperates with the side cardboard 101 on the side facing the volume of the carton. The buffer cardboard 201 is provided with buffer paper tubes 202 at equal intervals. A buffer inflatable tube 203 is penetrated between adjacent buffer paper tubes 202. The buffer inflatable tube 203 and the buffer paper tubes 202 are located between the buffer cardboard 201 and the side cardboard 101 to form a buffer area. The distance between the buffer areas is directly proportional to the air pressure inside the buffer inflatable tube 203. Each of the buffer paper tubes 202 and the buffer inflatable tube 203 has a buffering effect. With their cooperation, when the buffer inflatable tube 203 is filled with a certain amount of gas, the gap between the item and the carton can be reduced, reducing the shaking of the item inside the carton. At the same time, the cooperation between the two will further enhance the buffer and shock absorption effect, providing a better protection effect for the item;

[0036] As Figure 3 shown, according to the size and shape of the item, the carton can be made into a corresponding shape. Similarly, the buffer cardboard 201 can also be folded several times to fit the shape of the corresponding item;

[0037] As Figure 1 、 Figures 6 - 7 shown, further, the buffer inflatable tube 203 is located inside the buffer paper tube 202. The buffer paper tube 202 includes a first outer arc surface 202-1, a second outer arc surface 202-2, and an inner arc surface 202-3. The first outer arc surface 202-1 and the second outer arc surface 202-2 form the outer layer of the buffer paper tube 202, and the inner arc surface 202-3 is the inner layer of the buffer paper tube 202. The outer layer is composed of the first outer arc surface 202-1 and the second outer arc surface 202-2, and there is an axial notch 202a between them. The axial notch 202a is located at the contact between the buffer paper tube 202 and the side cardboard 101. A thick load-bearing layer 202a-1 is formed between the second outer arc surface 202-2 and the inner arc surface 202-3;

[0038] When the item contacts the buffer cardboard 201, the buffer paper tube 202 deforms, and the first outer arc surface 202-1 sinks towards the central axial notch 202a. During this period, the second outer arc surface 202-2 continues to deform to bear the pressure, and then the thick layer of the second outer arc surface 202-2 and the inner arc surface 202-3 contacts the buffer cardboard 201 to support the entire buffer paper tube 202;

[0039] As Figure 1 、 Figures 6 - 7As shown, further, the buffer charging tube 203 includes a main arc surface 203-1 and a pressure relief expansion arc surface 203-2. The main arc surface 203-1 and the pressure relief expansion arc surface 203-2 form an integral body, jointly constituting the buffer charging tube 203 with a cavity. The pressure relief expansion arc surface 203-2 is in contact with the side cardboard 101. The thickness of the pressure relief expansion arc surface 203-2 is less than that of the side cardboard 101. The buffer charging tube 203 is in a convex shape;

[0040] When the buffer paper tube 202 deforms and squeezes the gas inside the buffer charging tube 203, the main arc surface 203-1 and the pressure relief expansion arc surface 203-2 are squeezed and deformed. Continuing to squeeze, since the expansion arc surface 203-2 is thinner than the main arc surface 203-1, the expansion arc surface 203-2 continues to expand and squeeze the thick layers of the second outer arc surface 202-2 and the inner arc surface 202-3, further forming a trend of buffer and vibration reduction. At the same time, it can also play a role in supporting the buffer paper tube 202, ensuring that the buffer paper tube 202 is not deformed by pressure and can restore its original shape after the pressure is removed;

[0041] It is worth mentioning that for the buffer charging tube 203 and the buffer paper tube 202, all their structural surfaces have arc surfaces. The arc surface itself has good shear resistance and pressure resistance characteristics, so it can better play a role in absorbing energy and buffering items when the buffer charging tube 203 is located on the buffer paper tube 202.

[0042] Importantly, it should be noted that the structures and arrangements of the present application shown in multiple different exemplary embodiments are only illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible on the premise of substantially not deviating from the novel teachings and advantages of the subject matter described in this application (for example, the dimensions, scales, structures, shapes and proportions of various components, and parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, color, orientation changes, etc.). For example, an element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature, number or position of discrete elements can be changed or altered. Therefore, all such modifications are intended to be included within the scope of the present utility model.
