Detailed Implementation

[0051] 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.

[0052] To provide cushioning protection for products, materials such as pearl cotton, foam, or multi-layer cardboard are typically used to fill the gaps inside the packaging box during long-term transportation. For example, pearl cotton and foam need to be custom-cut in thickness and shape according to the size of the product and the packaging box. While these materials ensure sufficient thickness to support the cushioning strength required for transporting the product, the amount of cushioning material needed for a single product is large, resulting in a large packaging volume.

[0053] Based on the aforementioned technical problems, this utility model embodiment is proposed. This utility model embodiment may include a box body 1 and a cushioning liner 2. The cushioning liner 2 is located inside the box body 1 and is formed by folding an integrally molded cardboard sheet together with the box body 1. The folded cushioning liner 2 is provided with a groove 2001 for placing the product 4. The folded cushioning liner 2 cooperates with the box body 1 to form a bottom cushioning space and a side cushioning space, which, together with the top cushioning layer 3, wraps the product 4. Thus, the cushioning liner 2 and box body 1, formed by integrally folding cardboard, can meet the packaging strength required for placing the product 4, while also providing the cushioning strength required for transporting the product 4. This reduces the amount of materials required for each product 4 and the packaging volume of the product 4.

[0054] Reference Figure 1-6 This utility model provides a packaging box, which may include a box body 1 and a cushioning liner 2. The cushioning liner 2 is located inside the box body 1 and is formed by folding an integrally molded cardboard together with the box body 1. The folded cushioning liner 2 is provided with a groove 2001 for placing a product 4. The folded cushioning liner 2 cooperates with the box body 1 to form a bottom cushioning space and a side cushioning space, which, together with the top cushioning layer 3, wraps the product 4.

[0055] In this embodiment of the invention, the box body 1 and the cushioning liner 2 are formed by folding an integrally molded cardboard. That is, the box body 1 and the cushioning liner 2 are integrally molded structures, requiring only one die-cutting mold during production, thereby reducing the production cost of the box body 1 and the cushioning liner 2. In actual production, a die-cutting mold can be used to cut the cardboard to obtain the unfolded box body 1 and the cushioning liner 2. The unfolded box body 1 and the cushioning liner 2 are then folded to obtain the folded box body 1 and the folded cushioning liner 2 located within the box body 1.

[0056] The folded buffer liner 2 is provided with a groove 2001, wherein the groove 2001 is used to place the product 4. For example, the groove wall of the groove 2001 can form an abutment with the product 4, thereby defining the placement position of the product 4. The product 4 may include electronic devices such as gateways, smart switches, and smart control panels. The product 4 may also include other products that are easily damaged during transportation, which are not further limited here.

[0057] The folded cushioning liner 2, in conjunction with the box body 1, forms a bottom cushioning space and a side cushioning space. The bottom cushioning space can be understood as a bottom cavity with a certain structural strength formed by folding the cushioning liner 2 and the box body 1. Similarly, the side cushioning spaces can be understood as side cavities with a certain structural strength formed by folding the cushioning liner 2 and the box body 1. Therefore, when an external impact force is applied to the box body 1, the deformation of the box body 1 in the bottom and side cushioning spaces reduces the impact on the product 4, thus providing cushioning protection for the product 4.

[0058] The top cushioning layer 3 can be a cushioning structure formed of foam material or pearl cotton material, so that when the product 4 is placed in the groove 2001, the top cushioning layer 3 is placed on top of the product 4, thereby providing top cushioning for the product 4. On the one hand, by folding the one-piece molded cardboard to form the outer box body 1 and the cushioning liner 2, the molding cost of the packaging box can be reduced. Furthermore, the bottom cushioning space and side cushioning space obtained by folding can improve the overall structural strength of the cushioning liner 2 and reduce the thickness required for cushioning materials, thereby reducing the amount of cushioning materials required for each product 4 and the packaging volume of the product 4, and improving the applicability of the packaging box to the product 4.

[0059] Meanwhile, the box body 1 and the cushioning liner 2 are formed by folding a single piece of cardboard, which can improve the production efficiency of the packaging box. For example, when unfolded, it is in a flat state, which can save storage and transportation space for the packaging box, and further reduce the transportation cost of product 4 by reducing the packaging volume of product 4. In addition, the single-piece cardboard can be recycled or degraded, thereby improving the environmental performance of the packaging box.

[0060] An optional utility model embodiment, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the box body 1 may include a first folding surface 101, two second folding surfaces 102, a third folding surface 103, a fourth folding surface 104, and a fifth folding surface 105. The two second folding surfaces 102 are connected to the first folding surface 101 and are located on opposite sides of the first folding surface 101. The third folding surface 103 and the fourth folding surface 104 are connected to the first folding surface 101 and are located on opposite sides of the first folding surface 101. The fifth folding surface 105 is located on the side of the fourth folding surface 104 away from the first folding surface 101. The folded box body 1 is formed by folding the second folding surfaces 102, the third folding surface 103, the fourth folding surface 104, and the fifth folding surface 105 towards the center of the first folding surface 101. The third folding surface 103 is located at the top of the folded box body 1, and the fourth folding surface 104 is located at the bottom of the folded box body 1.

[0061] In this embodiment of the present invention, the two second folding surfaces 102 are respectively located on both sides of the first folding surface 101 and are opposite to each other. The third folding surface 103 and the fourth folding surface 104 are respectively located on the other two sides of the first folding surface 101 and are opposite to each other. The second folding surface 102, the third folding surface 103, the fourth folding surface 104, and the fifth folding surface 105 are respectively connected to the first folding surface 101. Thus, the second folding surface 102, the third folding surface 103, the fourth folding surface 104, and the fifth folding surface 105 are folded towards the center of the first folding surface 101. The folded second folding surface 102, the folded third folding surface 103, the folded fourth folding surface 104, and the folded fifth folding surface 105 are respectively arranged perpendicular to the first folding surface 101, and simultaneously form the folded box body 1. During folding, the folding is performed along the connecting edge of the two folding surfaces. For example, the second folding surface 102 is folded along the connecting edge with the first folding surface 101.

[0062] The third fold surface 103 is located at the top of the folded box body 1, which can also be understood as the top of the folded box body 1. The fourth fold surface 104 is located at the bottom of the folded box body 1, which can also be understood as the bottom of the folded box body 1. The first fold surface 101, the second fold surface 102, and the fifth fold surface 105 can be understood as the sides of the folded box body 1. Therefore, the box body 1 can be formed by folding an integrally molded cardboard, which can reduce the production process and mold opening cost of the packaging box, and improve the product packaging efficiency of the box body 1.

[0063] An optional utility model embodiment, referring to... Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, the box body 1 in its folded state has a side opening 1001. The box body 1 may also include a sixth folding surface 106 and a first latch 107. The sixth folding surface 106 is located on the side of the third folding surface 103 away from the first folding surface 101 and is connected to the third folding surface 103. In the folded state, the sixth folding surface 106 closes the side opening 1001. The first latch 107 is located on the side of the sixth folding surface 106 away from the third folding surface 103 and is connected to the sixth folding surface 106. The cushioning liner 2 includes a seventh folding surface 201, which is located on the side of the fifth folding surface 105 away from the fourth folding surface 104 and is connected to the fifth folding surface 105. The seventh folding surface 201 and the fifth folding surface 105 are connected by a first latching groove 1002, and the first latching tongue 107 is inserted into the first latching groove 1002 to fix the box body 1 in the folded state.

[0064] In this embodiment of the present invention, the box body 1 in the folded state has a side opening 1001, which is obtained by folding the first folding surface 101, the second folding surface 102, the third folding surface 103, the fourth folding surface 104, and the fifth folding surface 105. The side opening 1001 can be located on the side of the box body 1 in the folded state. The box body 1 may also include a sixth folding surface 106 and a first latch 107. The sixth folding surface 106 is located on the side of the third folding surface 103 away from the first folding surface 101, or it can be understood that the sixth folding surface 106 is located on the side of the third folding surface 103 and is opposite to the first folding surface 101. The sixth folding surface 106 connects with the third folding surface 103. The sixth folding surface 106 in the folded state can be obtained by folding the sixth folding surface 106 in the unfolded state along the connection point with the third folding surface 103 towards the fifth folding surface 105. Thus, the sixth fold surface 106 in its folded state closes the side opening 1001, thereby achieving overall closure of the box body 1.

[0065] The first latch 107 is used to fix the box body 1 after it has been folded and formed. The first latch 107 is located on the side of the sixth fold surface 106 away from the third fold surface 103. It can be understood that the first latch 107 can be located on one side of the sixth fold surface 106 and is opposite to the third fold surface 103. In one example, the first latch 107 can be located in the central area of ​​one side of the sixth fold surface 106.

[0066] The seventh fold surface 201 of the buffer liner 2 is located on the side of the fifth fold surface 105 away from the fourth fold surface 104. This can also be understood as the seventh fold surface 201 being located on one side of the fifth fold surface 105 and being opposite to the fourth fold surface 104, with the seventh fold surface 201 connecting to the fifth fold surface 105. A first latching groove 1002 is provided at the connection point between the seventh fold surface 201 and the fifth fold surface 105. For example, the first latching groove 1002 can be located in the central area of ​​the connection edge between the fifth fold surface 105 and the seventh fold surface 201, and the first latching tongue 107 is shape-fitted to the first latching groove 1002. The sixth fold surface 106 in the folded state is coplanar with the first latching tongue 107. The first latching tongue 107 is inserted into the first latching groove 1002 to secure the folded box body 1.

[0067] During the folding process of the packaging box, the first folding surface 101, the second folding surface 102, the fourth folding surface 104, and the fifth folding surface 105 are folded in advance, so that the top of the box body 1 in the folded state is in a freely foldable state, that is, the third folding surface 103 and the sixth folding surface 106 are in a foldable state. Thus, after the product 4 is placed in the groove 2001, the top buffer layer 3 is placed on top of the product 4, then the third folding surface 103 is folded to cover the product 4, and finally the sixth folding surface 106 is folded and the first latch 107 is inserted into the first latching slot 1002, thereby completing the packaging of the product 4.

[0068] An optional utility model embodiment, referring to... Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the box body 1 further includes two second latches 108, which are respectively located on the sixth folding surface 106 and distributed on different sides of the sixth folding surface 106 from the first latch 107. The second latches 108 are inserted into the contact gap between the second folding surface 102 and the sixth folding surface 106 to cooperate with the first latch 107 and fix the box body 1 in the folded state.

[0069] In this embodiment of the invention, the two second latches 108 are respectively located on the other two sides of the sixth folding surface 106, excluding the end side where the first latch 107 is located. For example, the second latches 108 can be located in the middle region of the end side of the sixth folding surface 106. The sixth folding surface 106 in the folded state is perpendicular to the second latches 108. That is, the second latches 108 are folded along their connecting edge with the sixth folding surface 106, so that the folded second latches 108 are inserted into the contact gap between the second folding surface 102 and the sixth folding surface 106. Thus, the folded box body 1 can be fixed by the cooperation of the first latch 107 and the second latches 108, and the connection structure strength of the packaging box can be improved.

[0070] An optional utility model embodiment, referring to... Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, the buffer liner 2 may further include two eighth fold surfaces 202, two ninth fold surfaces 203, and two tenth fold surfaces 204. The eighth fold surfaces 202 are disposed on one side of the second fold surface 102, and the ninth fold surfaces 203 are disposed on the side of the eighth fold surfaces 202 away from the second fold surface 102. The two eighth fold surfaces 202 in the folded state overlap with the fourth fold surface 104 in the folded state, and the two ninth fold surfaces 203 in the folded state contact each other to form a bottom support rib 2002. The bottom support rib 2002 is horizontally disposed with the second fold surface 102 in the folded state. The tenth fold surface 204 is located in the middle region of the seventh fold surface 201. The tenth fold surface 204 in the folded state is perpendicular to the seventh fold surface 201 in the folded state, and the tenth fold surface 204 has a second snap-fit ​​groove 2003. The bottom support rib 2002 is inserted into the second snap-fit ​​groove 2003. The first fold surface 101, the second fold surface 102, the fourth fold surface 104, the fifth fold surface 105 and the seventh fold surface 201 surround and form the bottom buffer space.

[0071] In this embodiment of the invention, the buffer liner 2 may further include two eighth folded surfaces 202, two ninth folded surfaces 203, and two tenth folded surfaces 204. The second folded surface 102, the eighth folded surface 202, and the ninth folded surface 203 are sequentially connected, meaning that the eighth folded surface 202 is located between the second folded surface 102 and the ninth folded surface 203. The eighth folded surface 202 in the folded state can be the eighth folded surface 202 in the unfolded state, folded along the connecting edge with the second folded surface 102 towards the direction close to the fourth folded surface 104. Thus, the two eighth folded surfaces 202 in the folded state overlap the fourth folded surface 104 in the folded state.

[0072] The ninth fold surface 203 in the folded state can be the ninth fold surface 203 in the unfolded state, folded along the connecting edge with the eighth fold surface 202 towards the direction close to the third fold surface 103. The two ninth fold surfaces 203 in the folded state contact each other to form a bottom support rib 2002, which is horizontally arranged with the second fold surface 102 in the folded state. In other words, the bottom support rib 2002 is perpendicular to the eighth fold surface 202 in the folded state.

[0073] The two tenth fold surfaces 204 are located in the middle region of the seventh fold surface 201. The folded tenth fold surface 204 can be obtained by folding the unfolded tenth fold surface 204 along its connecting edge with the seventh fold surface 201 towards the direction close to the folded fourth fold surface 104. The folded tenth fold surface 204 is perpendicular to the folded seventh fold surface 201, and a second snap-fit ​​groove 2003 is formed on the tenth fold surface 204 near the bottom support rib 2002. The second snap-fit ​​groove 2003 is shaped to fit the bottom support rib 2002, so that the bottom support rib 2002 can be inserted into the second snap-fit ​​groove 2003. For example, the bottom support rib 2002 is perpendicular to the folded tenth fold surface 204. Thus, the first fold surface 101, the second fold surface 102, the fourth fold surface 104, the fifth fold surface 105, and the seventh fold surface 201 enclose and form the bottom buffer space. Furthermore, the two second snap-fit ​​slots 2003 engage with the bottom support rib 2002, which can improve the strength of the support structure at the bottom buffer space while forming the bottom buffer space.

[0074] An optional utility model embodiment, referring to... Figure 1 As shown, a limiting groove 2004 is also provided on the seventh fold surface 201, and the two tenth fold surfaces 204 are respectively located on both sides of the limiting groove 2004, so that a part of the product 4 is inserted into the limiting groove 2004 to form a limiting position.

[0075] In this embodiment of the invention, a limiting groove 2004 is also formed on the seventh folded surface 201, and the two tenth folded surfaces 204 are respectively located on both sides of the limiting groove 2004. In other words, the limiting groove 2004 can be formed on the seventh folded surface 201 after the tenth folded surface 204 in its unfolded state is folded. In another embodiment, the limiting groove 2004 can also be formed on the seventh folded surface 201. A portion of the product 4 is inserted into the limiting groove 2004 to form a limiting position. For example, the limiting groove 2004 can be used to place the protruding part of the product 4, thereby preventing the product 4 from shaking in the groove 2001. Furthermore, the two folded tenth folded surfaces 204 respectively engage with the bottom support rib 2002 and are respectively located on both sides of the limiting groove 2004. This improves the structural support strength on both sides of the limiting groove 2004 and the support strength of the product 4 placed in the limiting groove 2004.

[0076] Furthermore, under the limiting action of the limiting groove 2004, when the product 4 is packaged in the box body 1, a certain gap is reserved between the folded sixth fold surface 106 and the product 4, thereby forming a buffer space for the product 4 through the gap. Alternatively, buffer material can be filled into the gap to provide a buffering effect.

[0077] An optional utility model embodiment, referring to... Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the buffer liner 2 may further include two eleventh fold surfaces 205, two twelfth fold surfaces 206, and a third latch 207. The eleventh fold surface 205 is located on the side of the second fold surface 102 closest to the third fold surface 103 and is connected to the second fold surface 102. The twelfth fold surface 206 is located on the side of the eleventh fold surface 205 away from the second fold surface 102 and is connected to the eleventh fold surface 205. In the folded state, the eleventh fold surface 205 and the folded twelfth fold surface 206 are perpendicularly arranged, and parallel to the folded seventh fold surface 201. The third latch 207 is located on the side of the twelfth fold surface 206 away from the eleventh fold surface 205 and is connected to the twelfth fold surface 206. A third latching groove 2005 is provided on the seventh folding surface 201, and the third latching tongue 207 is inserted into the third latching groove 2005 to form a fixed connection between the seventh folding surface 201 and the twelfth folding surface 206. The second folding surface 102, the seventh folding surface 201, the eleventh folding surface 205 and the twelfth folding surface 206 cooperate to form a first side buffer space.

[0078] In this embodiment of the present invention, the buffer liner 2 may further include two eleventh fold surfaces 205, two twelfth fold surfaces 206, and a third latch 207. The second fold surface 102, the eleventh fold surface 205, and the twelfth fold surface 206 are sequentially connected, and the eleventh fold surface 205 is located between the second fold surface 102 and the twelfth fold surface 206. The eleventh fold surface 205 in the folded state can be obtained by folding the eleventh fold surface 205 in the unfolded state along the connecting edge with the second fold surface 102 towards the direction close to the third fold surface 103, wherein the eleventh fold surface in the folded state overlaps with the third fold surface 103 in the folded state. The twelfth fold surface 206 in the folded state can be obtained by folding the twelfth fold surface 206 in the unfolded state along the connecting edge with the eleventh fold surface 205 towards the fourth fold surface 104. The twelfth fold surface 206 in the folded state is perpendicular to the eleventh fold surface 205 in the folded state and parallel to the second fold surface 102 in the folded state.

[0079] The third latch 207 is located on the side of the twelfth fold surface 206 away from the eleventh fold surface 205. For example, the third latch 207 can be located in the central area of ​​one side of the twelfth fold surface 206. A third latching groove 2005 is provided on the seventh fold surface 201. After the twelfth fold surface 206 is folded, the third latch 207 on the twelfth fold surface 206 is coplanar with the folded twelfth fold surface 206. The latching of the third latch 207 and the third latching groove 2005 forms a fixed connection between the seventh fold surface 201 and the twelfth fold surface 206. That is, the folded state of the twelfth fold surface 206 can be maintained by the latching of the third latch 207 and the third latching groove 2005. The second fold surface 102, the seventh fold surface 201, the eleventh fold surface 205, and the twelfth fold surface 206 fold together to form a first side buffer space. Therefore, when product 4 is placed above the seventh fold surface 201, sufficient structural strength support and cushioning strength can be provided to both sides of product 4 through the two first side buffer spaces. This greatly reduces the amount of cushioning materials used and significantly reduces the packaging volume of product 4.

[0080] An optional utility model embodiment, referring to... Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, the cushioning liner 2 may further include a thirteenth fold surface 208, a fourteenth fold surface 209, and a fifteenth fold surface 210. The thirteenth fold surface 208 is located on the side of the seventh fold surface 201 away from the fifth fold surface 105, and is connected to the seventh fold surface 201. The folded thirteenth fold surface 208 is perpendicular to the folded seventh fold surface 201. The fourteenth fold surface 209 is located on the side of the thirteenth fold surface 208 away from the seventh fold surface 201, and is connected to the thirteenth fold surface 208. The folded fourteenth fold surface 209 is parallel to the folded seventh fold surface 201. The fifteenth fold surface 210 is located on the side of the fourteenth fold surface 209 away from the thirteenth fold surface 208, and is connected to the fourteenth fold surface 209. The fifteenth fold surface 210 in the folded state is arranged parallel to the thirteenth fold surface 208 in the folded state. The thirteenth fold surface 208, the fourteenth fold surface 209, and the fifteenth fold surface 210 cooperate to form a second side buffer space.

[0081] In this embodiment of the invention, the buffer liner 2 may further include a thirteenth fold surface 208, a fourteenth fold surface 209, and a fifteenth fold surface 210. The seventh fold surface 201 is also present. The thirteenth fold surface 208, fourteenth fold surface 209, and fifteenth fold surface 210 are sequentially connected. That is, the thirteenth fold surface 208 is located between the seventh fold surface 201 and the fourteenth fold surface 209, and the fourteenth fold surface 209 is located between the thirteenth fold surface 208 and the fifteenth fold surface 210.

[0082] The thirteenth fold surface 208 in the folded state is obtained by folding the unfolded thirteenth fold surface 208 along its connecting edge with the seventh fold surface 201 towards the direction closer to the third fold surface 103. The fourteenth fold surface 209 in the folded state is obtained by folding the unfolded fourteenth fold surface 209 along its connecting edge with the thirteenth fold surface 208 towards the direction closer to the first fold surface 101. The fifteenth fold surface 210 in the folded state is obtained by folding the unfolded fifteenth fold surface 210 along its connecting edge with the fourteenth fold surface 209 towards the direction closer to the third fold surface 103. The thirteenth fold surface 208 and the fifteenth fold surface 210 in the folded state are arranged parallel to each other, and the thirteenth fold surface 208 and the fourteenth fold surface 209 in the folded state are arranged perpendicular to each other.

[0083] The thirteenth folding surface 208, the fourteenth folding surface 209, and the fifteenth folding surface 210 cooperate to form a second side buffer space. Thus, when the product 4 is placed above the seventh folding surface 201, the combination of the second side buffer space and the two first side buffer spaces can provide sufficient structural strength support and buffer strength for three sides of the product 4, thereby greatly reducing the usage amount of buffer consumables and greatly reducing the packaging volume of the product 4.

[0084] An optional embodiment of the utility model, referring to Figure 2 and Figure 3 As shown, a fourth clamping groove 2006 is formed on the fifteenth folding surface 210, and the bottom support rib 2002 is inserted into the fourth clamping groove 2006.

[0085] In the embodiment of the utility model, a fourth clamping groove 2006 is formed on the fifteenth folding surface 210 in the direction close to the bottom support rib 2002, and the bottom support rib 2002 is inserted into the fourth clamping groove 2006, that is, the fourth clamping groove 2006 is in clamping cooperation with the bottom support rib 2002, and the fifteenth folding surface 210 is vertically arranged with respect to the bottom support rib 2002. Thereby, the structural support strength and buffer strength at the second side buffer space can be improved.

[0086] In one or more embodiments, the clamping cooperation between the two second clamping grooves 2003 and the bottom support rib 2002, and the clamping cooperation between the fourth clamping groove 2006 and the bottom support rib 2002 can form a cross shape, which can greatly improve the structural support strength and buffer strength at the bottom buffer space and improve the buffer effect of the packaging box for transporting the product 4.

[0087] An optional embodiment of the utility model, referring to Figure 3 and Figure 4 As shown, two extension parts 2011 are arranged on the seventh folding surface 201, and the two extension parts 2011 are arranged on both sides of the thirteenth folding surface 208 and are in abutment with the third folding surface 103. Among them, being arranged on both sides of the thirteenth folding surface 208 can be understood as at both ends of the connection edge between the seventh folding surface 201 and the thirteenth folding surface 208. The extension parts 2011 are arranged coplanarly with the seventh folding surface 201 in the unfolded state. Thus, the extension parts 2011 are in abutment with the third folding surface 103, so that the buffer strength of the second side buffer space and the structural support strength of the seventh folding surface 201 in the folded state for the product 4 can be improved.

[0088] In one optional embodiment of the utility model, the seventh fold surface 201, the twelfth fold surface 206, and the thirteenth fold surface 208 cooperate to form the groove 2001. This allows the product 4 to be placed through the groove 2001. For example, when the product 4 is placed in the groove 2001, the sides of the product 4 can respectively abut against the seventh fold surface 201, the twelfth fold surface 206, and the thirteenth fold surface 208.

[0089] This utility model discloses a packaging box, which may include a box body 1 and a cushioning liner 2. The cushioning liner 2 is located inside the box body 1 and is formed by folding an integrally molded cardboard together with the box body 1. The folded cushioning liner 2 is provided with a groove 2001 for placing a product 4. The folded cushioning liner 2 cooperates with the box body 1 to form a bottom cushioning space and a side cushioning space, which, together with the top cushioning layer 3, wraps the product 4. Thus, the integrally folded cardboard liner 2 and box body 1 can provide the necessary packaging strength for placing the product 4, while also providing the cushioning strength required for transporting the product 4, thereby reducing the amount of materials required for each product 4 and the packaging volume of the product 4.

[0090] Reference Figure 6 As shown, this utility model embodiment also discloses a packaging component, which includes a top buffer layer 3 and a packaging box as described in any of the above utility model embodiments, wherein the top buffer layer 3 is located in the groove 2001 and above the product 4, so as to cooperate with the buffer liner 2 to wrap the product 4.

[0091] In this embodiment of the present invention, the top buffer layer 3 can be a buffer structure formed of foam material or pearl cotton material. During use, when the packaging assembly including any of the above embodiments of the present invention is placed in the groove 2001, the top buffer layer 3 can be placed above the product 4, thereby providing top buffering for the product 4. On one hand, by simultaneously folding the integrally molded cardboard to form the outer box body 1 and the buffer liner 2, the molding cost of the packaging box can be reduced. Furthermore, the bottom buffer space and side buffer space obtained through folding can improve the overall structural strength of the buffer liner 2 and reduce the thickness required for buffering materials, thereby reducing the amount of buffering materials required for each product 4 and the packaging volume of the product 4, and improving the applicability of the packaging assembly to the product 4.

[0092] In summary, this utility model discloses a packaging component. The packaging box may include a box body 1 and a cushioning liner 2. The cushioning liner 2 is located inside the box body 1 and is formed by folding an integrally molded cardboard together with the box body 1. The folded cushioning liner 2 is provided with a groove 2001 for placing a product 4. The folded cushioning liner 2 cooperates with the box body 1 to form a bottom cushioning space and a side cushioning space, which, together with the top cushioning layer 3, wraps the product 4. Therefore, the integrally folded cardboard cushioning liner 2 and box body 1 can provide the necessary packaging strength for placing the product 4, while also providing the cushioning strength required for transporting the product 4. This reduces the amount of materials required for each product 4 and the packaging volume of the product 4.
