[0022] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0023] To prevent products from being damaged by bumps and collisions during transportation, the industry commonly uses cushioning materials such as pearl cotton and foam to wrap the products before placing them in a box. In practice, the thickness of the cushioning material must be precisely cut and its shape customized to ensure that the cushioning structure provides sufficient cushioning strength for the product to achieve effective protection.
[0024] However, while this packaging solution achieves the protective effect, it also has the following two problems: First, the consumption of cushioning material required for a single product is high; second, the cushioning material will significantly increase the overall packaging volume, which not only occupies more transportation space, but also indirectly increases logistics and transportation costs.
[0025] Based on the aforementioned technical problems, this application proposes an embodiment that may include a box body and a cushioning liner. The cushioning liner is located within the box body and is formed by folding an integrally molded cardboard sheet together with the box body. The folded cushioning liner has a receiving space for accommodating a product. The folded cushioning liner has a limiting groove that communicates with the receiving space to limit the position of the product within the space. Thus, by using an integrally folded cardboard sheet and box body, the required packaging strength for product placement is met while the limiting groove restricts the product's position, providing cushioning through the cavity formed between the box body and the cushioning liner. While meeting the required cushioning strength for product transportation, the amount of materials required for each product and the packaging volume can be reduced.
[0026] Reference Figure 1-7 This application provides a packaging box, which may include a box body 100 and a cushioning liner 200. The cushioning liner 200 is located inside the box body 100 and is formed by folding an integrally molded cardboard together with the box body 100. The folded cushioning liner 200 is provided with a receiving space 201 for receiving a product 300. The folded cushioning liner 200 has a limiting groove 202, which communicates with the receiving space 201 to limit the position of the product 300 located within the receiving space 201.
[0027] In this embodiment, the cushioning liner 200 and the box body 100 are formed by folding an integrally molded cardboard. This can be understood as the cushioning liner 200 and the box body 100 being a single integrated structure, obtained through an integral molding process. For example, the cardboard to be processed is cut using a die to obtain the unfolded packaging box. In other words, the unfolded box body 100 and the unfolded cushioning liner 200 are obtained. On one hand, the unfolded packaging box is a flat plate, allowing for high-density stacking in a small space, thereby reducing the storage and transportation space of the packaging box, and lowering the transportation and logistics costs. On the other hand, using an integrally molded cardboard to fold the packaging box into a folded state improves the production efficiency of the packaging box.
[0028] The folded cushioning liner 200 is located within the box body 100 and has a receiving space 201. The receiving space 201 provides a placement space for the product 300 to be packaged. The folded cushioning liner 200 provides the necessary cushioning strength for the product 300. For example, the folded cushioning liner 200 has a limiting groove 202, which communicates with the receiving space 201 and serves to limit the position of the product 300. During the folding process of the packaging box, one side of the product 300 entering the receiving space 201 can be placed in the limiting groove 202. The shape fit between the limiting groove 202 and the product 300 defines the position of the product 300 within the receiving space 201. For example, at least two limiting grooves 202 can be provided. Under the limiting effect of at least two limiting grooves 202, the product 300 can be prevented from moving within the box 100, thereby providing structural support for the product 300.
[0029] Therefore, based on the above structural design, while meeting the packaging strength required for placing product 300, the limiting groove 202 formed by folding limits the position of product 300, and the cavity formed between box body 100 and cushioning liner 200 provides cushioning for product 300. While meeting the cushioning strength required for transporting packaged product 300, the amount of materials required for each product 300 and the packaging volume of product 300 can be reduced, which is beneficial for reducing the logistics and / or express delivery costs of the product 300.
[0030] In this embodiment, the product 300 may include, but is not limited to, electronic devices such as gateways, smart switches, and smart control screens. Alternatively, other products 300 that are easily damaged during transportation are also included, without further limitation.
[0031] In one or more embodiments, refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 as well as Figure 7As shown, the box body 100 may include a first folding surface 110, two second folding surfaces 120, a third folding surface 130, a fourth folding surface 140, and a fifth folding surface 150. The first folding surface 110 in its folded state serves as the bottom surface of the box body 100. The two second folding surfaces 120 connect to the first folding surface 110 and are located opposite to the first folding surface 110, serving as the side surfaces of the box body 100 in their folded state. The third folding surface 130 connects to the first folding surface 110 and is adjacent to the second folding surfaces 120, serving as the back surface of the box body 100 in its folded state. The fourth folding surface 140 connects to the side of the third folding surface 130 away from the first folding surface 110, serving as the top surface of the box body 100 in its folded state. The fifth folding surface 150 connects to the side of the fourth folding surface 140 away from the third folding surface 130, wherein the fifth folding surface 150 in the folded state serves as the front of the box body 100. The first folding surface 110 in the folded state is inserted and fixed to the fifth folding surface 150 in the folded state.
[0032] In this embodiment of the application, the box body 100 may include a first folding surface 110, two second folding surfaces 120, a third folding surface 130, a fourth folding surface 140, and a fifth folding surface 150. That is, the box body 100 includes six folding surfaces, and by directionally folding the six folding surfaces in the unfolded state, a closed hexahedron that can accommodate the buffer liner 200 and the product 300 can be obtained.
[0033] Correspondingly, the box body 100 in its folded state may include a bottom surface, two side surfaces, a back surface, a top surface, and a front surface. The first folding surface 110 in the folded state serves as the bottom surface of the box body 100. Two second folding surfaces 120 connect with the first folding surface 110 and are located on opposite sides of the first folding surface 110. The second folding surfaces 120 in the folded state can be obtained by folding the second folding surface 120 in its unfolded state 90 degrees towards each other along the connection point with the unfolded first folding surface 110. Thus, the two second folding surfaces 120 in the folded state can serve as the left and right sides of the box body 100 in its folded state, respectively.
[0034] The third folding surface 130 connects to the first folding surface 110 and is adjacent to the second folding surface 120. It can be understood that the third folding surface 130 is located between the two second folding surfaces 120. The folded third folding surface 130 can be obtained by folding the unfolded third folding surface 130 90 degrees along its connection with the first folding surface 110. The folded third folding surface 130 can serve as the back surface of the folded box body 100.
[0035] The fourth fold surface connects to the side of the third fold surface 130 away from the first fold surface 110. That is, the fourth fold surface 140 and the first fold surface 110 are respectively located on two opposite sides of the third fold surface 130. The fourth fold surface 140 in the folded state can be obtained by folding the fourth fold surface 140 in the unfolded state along the connection with the third fold surface 130 by 90 degrees. The fourth fold surface 140 in the folded state is parallel to the first fold surface 110 in the folded state, and the fourth fold surface 140 in the folded state can serve as the top surface of the box body 100 in the folded state.
[0036] The fifth fold surface 150 connects to the side of the fourth fold surface 140 away from the third fold surface 130, meaning that the fifth fold surface 150 and the third fold surface 130 are located on opposite sides of the fourth fold surface 140. The fifth fold surface 150 in the folded state can be obtained by folding the unfolded fifth fold surface 150 90 degrees along its connection with the fourth fold surface 140. The fifth fold surface 150 in the folded state is parallel to the third fold surface 130 in the folded state, and the fifth fold surface 150 in the folded state can serve as the front of the box body 100 in the folded state.
[0037] The first folded surface 110 in its folded state contacts the fifth folded surface 150 in its folded state and is fixed by insertion. Therefore, based on the above structural design, and with the cushioning liner 200 limiting the product 300, combined with the integrally folded box body 100, the cushioning liner 200 and the product 300 can be quickly sealed. Furthermore, the box body 100 in its folded state can be fixed without the use of tape or glue, preventing the packaging box from becoming structurally loose. This not only improves the packaging efficiency of the box but also optimizes its environmental performance.
[0038] In one or more embodiments, refer to Figure 1 , Figure 3 as well as Figure 4As shown, the cushioning liner 200 may include two first liner bodies 210 and a second liner body 220. The first liner body 210, in its folded state, is located on the inner side of the box body 100, wherein the limiting groove 202 is provided on the first liner body 210. The second liner body 220, in its folded state, is located on the inner bottom surface of the box body 100, wherein the two first liner bodies 210 and the second liner body 220, in their folded states, enclose and form the accommodating space 201.
[0039] In this embodiment, the cushioning liner 200 may include a second liner body 220 and two first liner bodies 210. The first liner body 210 in a folded state is located on the inner side of the box body 100. That is, the two folded first liner bodies 210 can respectively contact the two folded second folded surfaces 120. The limiting groove 202 is provided on the first liner body 210. During the packaging process of the product 300, the first side of the product 300 can be inserted into the limiting groove 202 of the first folded first liner body 210. Then, the second side of the product 300 is inserted into the limiting groove 202 of the second folded first liner body 210. Thus, the limiting engagement between the two limiting grooves 202 and the product 300 limits the position of the product 300 in the box body 100, preventing the product 300 from shaking.
[0040] The second inner lining body 220 in its folded state is located on the inner bottom surface of the box body 100, which can also be understood as the second inner lining body 220 in its folded state contacting the first folding surface 110 in its folded state. The two first inner lining bodies 210 and the second inner lining body 220 in their folded states enclose and form the accommodating space 201.
[0041] Based on the above structural design, the product 300, within the accommodating space 201 and limited by the limiting groove 202, can improve the internal structural strength of the packaging box through the first inner liner body 210 and the second inner liner body 220, and provide the required cushioning strength for the product 300 through the cavity formed between the cushioning liner 200 and the box body 100, thereby reducing the required material consumption and packaging volume of each product 300.
[0042] In one or more embodiments, refer to Figure 1 , Figure 4 as well as Figure 7 As shown, when the limiting groove 202 and the product 300 form a limiting position, the second inner liner body 220 is used to contact the product 300.
[0043] In this embodiment, the second inner liner body 220 in its folded state can come into contact with the product 300 located in the accommodating space 201, thereby providing structural support for the product 300. Based on the above structural design, the product 300 is provided with dual structural support by the limiting groove 202 and the second inner liner body 220, thereby improving the placement stability of the product 300. For example, the contact between the second inner liner body 220 and the product 300 can reduce the amplitude of shaking caused by assembly errors (also known as engagement errors) between the limiting groove 202 and the product 300.
[0044] In one or more embodiments, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 as well as Figure 7 As shown, the first inner lining body 210 may include two sixth folded surfaces 211, two seventh folded surfaces 212, and two eighth folded surfaces 213. The two sixth folded surfaces 211 are located on opposite sides of the second folded surface 120. The two seventh folded surfaces 212 are located on the side of the sixth folded surfaces 211 away from the second folded surface 120, wherein the folded seventh folded surfaces 212 are parallel to the folded second folded surface 120, and a first groove 2101 is formed on the seventh folded surfaces 212. The two eighth folded surfaces 213 are located on the side of the seventh folded surfaces 212 away from the sixth folded surfaces 211, wherein the folded eighth folded surfaces 213 are parallel to the folded sixth folded surfaces 211, and the first groove 2101 extends onto the eighth folded surfaces 213. The two first grooves 2101 in the folded state cooperate to form the limiting groove 202. The second folded surface 120, the sixth folded surface 211, the seventh folded surface 212, and the eighth folded surface 213 in the folded state form a side buffer cavity.
[0045] In this embodiment of the application, for a single inner lining body, each first inner lining body 210 may include two sixth folded surfaces 211, two seventh folded surfaces 212, and two eighth folded surfaces 213.
[0046] The two sixth fold surfaces 211 are located on opposite sides of the second fold surface 120 and are respectively connected to the second fold surface 120. For example, the sixth fold surface 211 in the folded state is the same as the sixth fold surface 211 in the unfolded state, obtained by folding it 90 degrees along the connection with the second fold surface 120.
[0047] The two seventh fold surfaces 212 are located on the side of the sixth fold surface 211 away from the second fold surface 120. That is, each seventh fold surface 212 connects to the sixth fold surface 211 and is located on opposite sides of the sixth fold surface 211, respectively, along with the second fold surface 120. The folded seventh fold surface 212 is obtained by folding the unfolded seventh fold surface 212 90 degrees along its connection with the sixth fold surface 211. The folded seventh fold surface 212 is parallel to the folded second fold surface 120, and a first groove 2101 is formed on the seventh fold surface 212.
[0048] Two eighth fold surfaces 213 are located on the side of the seventh fold surface 212 away from the sixth fold surface 211. That is, each eighth fold surface 213 connects to the seventh fold surface 212 and is located on opposite sides of the sixth fold surface 212. The folded eighth fold surface 213 is obtained by folding the unfolded eighth fold surface 213 90 degrees along its connection with the seventh fold surface 212. The folded eighth fold surface 213 is parallel to the folded sixth fold surface 211. That is, the folded eighth fold surface 213 contacts the folded second fold surface 120. The first groove 2101 extends to the eighth fold surface 213, and the two first grooves 2101 in the folded state cooperate to form the limiting groove 202. The folded eighth fold surface 213 forms reinforcing ribs along the height direction of the packaging box. This can improve the structural strength of the first inner liner body 210, enhance the overall impact resistance and load-bearing capacity of the packaging box, and thus further improve the protective performance of the product 300.
[0049] The second fold surface 120, the sixth fold surface 211, the seventh fold surface 212, and the eighth fold surface 213 in their folded states form a side buffer cavity. When the product 300 is precisely engaged via the limiting groove 202, the side buffer cavity provides buffer space on both sides of the product 300. Furthermore, the fixed position of the product 300 within the packaging box creates a comprehensive buffer space between the product 300 and the box body 100.
[0050] Based on the above structural design, the structural strength of the packaging box can be improved, the protective performance of the packaging box for the product 300 can be improved, and the all-round buffer space can reduce the risk of collision damage to the product 300 under external impact force during transportation or storage.
[0051] In one or more embodiments, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, the two eighth folded surfaces 213 in the folded state form surface contact.
[0052] In this embodiment, the two eighth folding surfaces 213 in the folded state form a surface contact, which can improve the structural support strength of the first inner lining body 210 for the product 300, and can prevent the two eighth folding surfaces 213 in the folded state from becoming structurally loose.
[0053] In one or more embodiments, refer to Figure 5 , Figure 6 as well as Figure 7 As shown, the first inner lining body 210 may further include two ninth fold surfaces 214. The two ninth fold surfaces 214 are located on the side of the eighth fold surface 213 away from the seventh fold surface 212. The ninth fold surface 214 in the folded state forms surface contact with the second fold surface 120 in the folded state and is arranged parallel to the seventh fold surface 212 in the folded state.
[0054] In this embodiment, each first inner lining body 210 may further include two ninth folded surfaces 214. The two ninth folded surfaces 214 are located on the side of the eighth folded surface 213 away from the seventh folded surface 212. This can be understood as the two ninth folded surfaces 214 connecting to the eighth folded surface 213, and the ninth folded surfaces 214 and the seventh folded surface 212 being located on opposite sides of the eighth folded surface 213. The folded ninth folded surface 214 can be obtained by folding the unfolded ninth folded surface 214 90 degrees along its connection with the eighth folded surface 213. The folded ninth folded surface 214 forms surface contact with the folded second folded surface 120 and is arranged parallel to the folded seventh folded surface 212. On one hand, the close fit between the folded ninth folded surface 214 and the folded second folded surface 120 can improve the structural support strength of the first inner lining body 210 and prevent structural loosening of the folded first inner lining body 210. The ninth fold surface 214 in the folded state is arranged parallel to the seventh fold surface 212 in the folded state, which can improve the positional accuracy of the limiting groove 202 on the first inner liner body 210 in the folded state, realize the precise positioning of the limiting groove 202 on the product 300, and prevent the product 300 from shaking inside the box 100.
[0055] Based on the above structural design, the overall structural strength and load-bearing capacity of the packaging box can be improved, and the first inner liner body 210 can be prevented from becoming structurally loose and the product 300 can be prevented from shaking inside the packaging box.
[0056] In one or more embodiments, refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the first inner lining body 210 may further include a tenth fold surface 215 and two eleventh fold surfaces 216. The tenth fold surface 215 is located on the side of the second fold surface 120 away from the first fold surface 110. The two eleventh fold surfaces 216 are spaced apart on the side of the tenth fold surface 215 away from the second fold surface 120, and the eleventh fold surfaces 216 in the folded state form surface contact with the seventh fold surface 212 in the folded state.
[0057] In this embodiment, each of the first inner lining bodies 210 may further include a tenth fold surface 215 and two eleventh fold surfaces 216. The tenth fold surface 215 is located on the side of the second fold surface 120 away from the first fold surface 110, which can be understood as the tenth fold surface 215 connecting with the second fold surface 120, and the tenth fold surface 215 and the first fold surface 110 being located on opposite sides of the second fold surface 120 respectively. The tenth fold surface 215 in the folded state is obtained by folding the tenth fold surface 215 in the unfolded state along the connection point with the second fold surface 120 by 90 degrees. The tenth fold surface 215 in the folded state is parallel to the first fold surface 110 in the folded state and forms surface contact with the fourth fold surface 140 in the folded state.
[0058] The two eleventh fold surfaces 216 are spaced apart on the side of the tenth fold surface 215 away from the second fold surface 120. This can be understood as the two eleventh fold surfaces 216 being located on the same side of the tenth fold surface 215, with the eleventh fold surface 216 and the second fold surface 120 respectively located on opposite sides of the tenth fold surface 215. The folded eleventh fold surface 216 is obtained by folding the unfolded eleventh fold surface 216 90 degrees along its junction with the tenth fold surface 215. The folded eleventh fold surface 216 forms surface contact with the folded seventh fold surface 212.
[0059] Based on the above structural design, on the one hand, the eleventh fold surface 216 is folded and inserted into the side buffer cavity, which can prevent the first inner liner body 210 from becoming structurally loose in the folded state, thereby improving the structural support strength of the first inner liner body 210 and the buffering strength of the side buffer cavity. On the other hand, the tenth fold surface 215 fits snugly against the top surface of the box body 100, and the tenth fold surface 215 in the folded state can provide structural support to the top surface of the box body 100, thereby improving the impact resistance of the packaging box.
[0060] In one or more embodiments, refer to Figure 1-7 As shown, the second inner lining body 220 may include a twelfth fold surface 221, a thirteenth fold surface 222, and a fourteenth fold surface 223. The twelfth fold surface 221 is connected to the first fold surface 110. The thirteenth fold surface 222 is located on the side of the twelfth fold surface 221 away from the first fold surface 110, wherein the folded thirteenth fold surface 222 is parallel to the folded first fold surface 110. The fourteenth fold surface 223 is located on the side of the thirteenth fold surface 222 away from the twelfth fold surface 221, and the folded fourteenth fold surface 223 is parallel to the folded twelfth fold surface 221. The folded first fold surface 110, the folded twelfth fold surface 221, the folded thirteenth fold surface 222, and the folded fourteenth fold surface 223 form a bottom buffer cavity.
[0061] In this embodiment of the application, the second inner lining body 220 may include a twelfth fold surface 221, a thirteenth fold surface 222, and a fourteenth fold surface 223.
[0062] The twelfth fold surface 221 connects with the first fold surface 110. For example, the twelfth fold surface 221 and the third fold surface 130 are located on opposite sides of the first fold surface 110. The folded twelfth fold surface 221 is obtained by folding the unfolded twelfth fold surface 221 90 degrees along the connection point with the first fold surface 110. The folded twelfth fold surface 221 and the folded third fold surface 130 are arranged parallel to each other.
[0063] The thirteenth fold surface 222 is located on the side of the twelfth fold surface 221 away from the first fold surface 110, wherein the thirteenth fold surface 222 and the first fold surface 110 are respectively located on two opposite sides of the twelfth fold surface 221. The folded thirteenth fold surface 222 is obtained by folding the unfolded thirteenth fold surface 222 at a 90-degree angle along the junction with the twelfth fold surface 221. The folded thirteenth fold surface 222 is arranged parallel to the folded first fold surface 110.
[0064] The fourteenth fold surface 223 is located on the side of the thirteenth fold surface 222 away from the twelfth fold surface 221. The fourteenth fold surface 223 and the twelfth fold surface 221 are respectively located on opposite sides of the thirteenth fold surface 222. The fourteenth fold surface 223 in the folded state is obtained by folding the fourteenth fold surface 223 in the unfolded state along the junction with the thirteenth fold surface 222 by 90 degrees. The fourteenth fold surface 223 in the folded state and the twelfth fold surface 221 in the folded state are arranged in parallel. Thus, the first fold surface 110 in the folded state, the twelfth fold surface 221 in the folded state, the thirteenth fold surface 222 in the folded state, and the fourteenth fold surface 223 in the folded state form a bottom buffer cavity.
[0065] Based on the above structural design, the second inner liner body 220 can improve the structural strength of the bottom buffer cavity of the box body 100, effectively offset the tension of the cardboard and stably support the bottom tray of the product 300, thereby improving the impact resistance and cushioning strength of the packaging box. This reduces the risk of collision damage to the product 300 under bottom impact forces during transportation or storage.
[0066] In one or more embodiments, refer to Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, the fourteenth fold surface 223 in the folded state forms surface contact with the third fold surface 130 in the folded state.
[0067] In this embodiment, the mutual contact between the fourteenth fold surface 223 and the third fold surface 130 in the folded state can improve the structural locking strength of the second inner lining body 220, preventing the second inner lining body 220 from opening and becoming structurally loose when the product 300 is placed on it. This also improves the structural support of the second inner lining body 220 for the back of the box 100, and enhances the structural strength and cushioning strength of the packaging box.
[0068] In one or more embodiments, refer to Figure 1 , Figure 3 , Figure 4 as well as Figure 7 As shown, the two sides of the thirteenth fold surface 222 in the folded state respectively form surface contact with the two first inner lining bodies 210.
[0069] In this embodiment, the two sides of the thirteenth fold surface 222 in the folded state are respectively abutted against the two first inner lining bodies 210. This improves the structural locking strength of the second inner lining body 220, preventing the folded second inner lining body 220 from opening and becoming structurally loose when the product 300 is placed on it. This also improves the structural support strength between the first inner lining body 210 and the second inner lining body 220, and further enhances the structural strength and cushioning strength of the packaging box.
[0070] In one or more embodiments, refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 as well as Figure 7 As shown, the box body 100 also includes a first latch 160, which is connected to the fifth folding surface 150. A first snap-fit groove 101 is provided at the connection between the second inner liner body 220 and the first folding surface 110. The first latch 160 is inserted into the first snap-fit groove 101 to fix the first folding surface 110 and the fifth folding surface 150 in the folded state.
[0071] In this embodiment, the box body 100 may further include a first latch 160, which connects to the fifth folding surface 150. For example, the first latch 160 and the fourth folding surface 140 are respectively located on two opposite sides of the fifth folding surface 150. A first locking groove 101 is provided at the connection between the second inner liner body 220 and the first folding surface 110. For example, when the product 300 is placed in the accommodating space 201 to close the box body 100, the first latch 160 in its unfolded state can be folded 90 degrees along the connection with the fifth folding surface 150 and inserted into the first locking groove 101. Thus, the first folding surface 110 and the fifth folding surface 150 in their folded state can be fixed by the insertion between the first latch 160 and the first locking groove 101, thereby forming a structural lock for the box body in its folded state.
[0072] Based on the above structural design, the folded box 100 can be secured without the use of tape or glue, preventing the packaging box from becoming structurally loose during folding. This not only improves the packaging efficiency of the box but also optimizes its environmental performance.
[0073] In one or more embodiments, refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 as well as Figure 7 As shown, the box body 100 also includes a second latch 170, which is connected to the first folding surface 110 and located in the first latching groove 101. A second latching groove 102 is provided at the connection between the fifth folding surface 150 and the first latch 160. The second latch 170 is inserted into the second latching groove 102 to fix the first folding surface 110 and the fifth folding surface 150 in the folded state for a second time.
[0074] In this embodiment of the application, the box body 100 may further include a second latch 170, which is connected to the first folding surface 110. That is, the second latch 170 and the third folding surface 130 are respectively located on two opposite sides of the first folding surface 110.
[0075] The second latch 170 is located in the first latching groove 101, and a second latching groove 102 is provided at the connection between the fifth folding surface 150 and the first latch 160. When the product 300 is placed in the accommodating space 201 to close the box 100, the first latch 160 in the unfolded state can be folded 90 degrees along the connection with the fifth folding surface 150 and inserted into the first latching groove 101. Thus, the first folding surface 110 and the fifth folding surface 150 in the folded state are fixed by the insertion between the first latch 160 and the first latching groove 101, thereby forming the first structural lock of the box in the folded state. At this time, the second latch 170 can be located on the outer surface of the box.
[0076] Then, the second latch 170 in the unfolded state is folded 90 degrees along the connection with the first folding surface 110 and inserted into the second latching groove 102. Thus, the first folding surface 110 and the fifth folding surface 150 in the folded state are fixed by the insertion between the second latch 170 and the second latching groove 102, thereby forming a second structural lock of the box in the folded state.
[0077] Based on the above structural design, when the product 300 is placed in the buffer liner 200 and the packaging box is closed, the double-layer latch locking structure can prevent the packaging box from becoming loose during transportation or storage, thereby improving the structural strength of the packaging box.
[0078] In summary, this application discloses a packaging box, which may include a box body 100 and a cushioning liner 200. The cushioning liner 200 is located inside the box body 100 and is formed by folding an integrally molded cardboard together with the box body 100. The folded cushioning liner 200 has a receiving space 201 for accommodating a product 300. The folded cushioning liner 200 has a limiting groove 202 that communicates with the receiving space 201 to limit the position of the product 300 within the receiving space 201. Thus, the integrally folded cardboard cushioning liner 200 and box body 100 can simultaneously meet the packaging strength requirements for placing the product 300, while the limiting groove 202 restricts the position of the product 300, thereby providing cushioning for the product 300 through the cavity formed between the box body 100 and the cushioning liner 200. While meeting the cushioning strength requirements for transporting product 300, the amount of materials required for each product 300 and the packaging volume of product 300 can be reduced.
