In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0066] Combine the following Figure 1-Figure 16 The structures of the cushioning liner, folding paperboard and product packaging provided in the embodiments of the present application are described in detail.

[0067] A certain embodiment of the present application provides a buffer liner 10, the structure of which is as follows: Figure 1-Figure 2As shown, the buffer lining 10 includes a side panel 11, a buffer component 12 and a matching component 13, wherein the side panel 11 extends along a first direction and has two first side edges 111 arranged opposite to each other in a second direction, and the first direction and the second direction are orthogonal; there is at least one buffer component 12, any one of the buffer components 12 is connected to the side panel 11 via the first side edge 111 and can be folded and moved relative to the side panel 11, and the free end of the buffer component 12 is connected to the middle part of the side panel 11 via the matching component 13 to form a buffer space between the side panel 11 and the buffer component 12.

[0068] The buffer liner 10 is made of cardboard, which can be corrugated paper or other common paper packaging materials, which is more environmentally friendly than traditional materials such as pearl cotton and bubble bags. In addition, the buffer liner 10 made of cardboard can be folded to form a three-dimensional structure under the action of the side plate 11, the buffer member 12 and the matching component 13, and a hollow buffer space is formed between the side plate 11 and the buffer member 12, so as to provide a better circumferential buffer and limit effect for the relevant products, especially the rod-shaped lamps, in the circumferential direction, so as to achieve the purpose of providing excellent buffer performance for at least one side of the product in the circumferential direction.

[0069] It should be noted that the actual distribution position, quantity, size, etc. of the above-mentioned buffer 12 can be adjusted according to the size of the product and packaging requirements. For example, when the relevant product has only one side in the circumferential direction that needs buffer packaging, the buffer 12 can be adjusted to extend only along a first side edge 111 of the side plate 11; when the relevant product has at least two sides in the circumferential direction that need buffer protection, the buffer 12 can be adjusted to be arranged toward the part of the product that needs buffer protection and the buffer 12 can be evenly or staggeredly distributed on the two first side edges 111 of the side plate 11; when the relevant product only needs buffer protection in a certain part in the axial direction, the buffer 12 can be adjusted to be distributed only in the part of the side plate 11 in the first direction (i.e., axial direction) toward the product that needs buffer protection, so as to match the shape of the product and reduce the waste of packaging materials.

[0070] In addition, the two first side edges 111 arranged opposite to each other in the second direction are mostly arranged to extend along the first direction. Figure 1 In actual processing, the actual extension direction of the first side edge 111 can be adaptively adjusted according to the size of the product and packaging requirements, and the two first side edges 111 can be set to be parallel to each other, or a certain angle can be set between the two first side edges 111. This embodiment does not limit the actual extension direction of the first side edge 111.

[0071] In some embodiments, the buffer 12 and the side panel 11 can be arranged as an integrated structure, that is, the side panel 11 extends outward through the first side edge 111 to form a plate-like buffer 12 structure that is folded and connected to the side panel 11; or, the buffer 12 can be arranged to be connected by gluing or nailing to achieve a folding connection between the buffer 12 and the side panel 11.

[0072] like Figure 1 and Figure 2 As shown, the buffer 12 can be folded relative to the side plate 11 so that its free end is close to or away from the side plate 11. When the free end of the buffer 12 is folded close to the side plate 11 and connected to the middle part of the side plate 11 (referring to the non-edge area of ​​the side plate 11) through the matching component 13, a hollow buffer structure is formed between the side plate 11 and the buffer 12. For structural stability considerations, the above-mentioned buffer space is a triangular structure in the first direction.

[0073] In order to ensure that a stable triangular buffer space can be formed after the buffer member 12 is folded and connected to the side panel 11, in some embodiments, the buffer member 12 is provided with a first bending line 121, and the buffer member 12 is divided into a connecting plate 122 and a contact plate 123 along the first bending line 121, wherein the connecting plate 122 is connected to the side panel 11 via the first side edge 111, and is used to connect the side panel 11 and the contact plate 123, and the contact plate 123 can be folded along the first bending line 121 toward one side of the connecting plate 122 and point to the side panel 11.

[0074] like Figure 2 As shown, the first bending line 121 is parallel to the first side edge 111. When the buffer 12 is folded relative to the side plate 11 via the first side edge 111, the free end of the contact plate 123 bent via the first bending line 121 can contact the surface of the side edge through the matching component 13.

[0075] Specifically, the mating component 13 for connecting the contact plate 123 and the side plate 11 may be a strip adhesive layer formed in at least one of the corresponding area in the middle of the side plate 11 and the free end of the contact plate 123, or may be other structures disclosed in the prior art for achieving detachable connection.

[0076] like Figure 1 and Figure 2 As shown, in some embodiments, the mating member 13 includes a first plug tongue 131 and a first socket 132 that fit together, wherein the first plug tongue 131 is formed at the free end of the contact plate 123, and the first socket 132 is formed at a relevant position of the side plate 11. When the contact plate 123 is folded and points to the side plate 11, the first plug tongue 131 can be inserted into the first socket 132, thereby realizing a detachable connection between the contact plate 123 and the side plate 11.

[0077] Specifically, the first inserting tongue 131 is a limit block that at least partially protrudes outward relative to the side edge of the free end of the contact plate 123, and the first inserting opening 132 is a strip-shaped hole. The limit block can be inserted into the strip-shaped hole.

[0078] It should be noted that, in order to ensure that the contact plate 123 and the mating plate 214 can be firmly connected, in some embodiments, the size of the first plug tongue 131 can be set to be not less than the size of the first socket 132; for example, the length of the first plug tongue 131 in the first direction is greater than the length of the first socket 132 in the first direction and the first plug tongue 131 is an overflow structure, such as Figure 2 After being inserted into the first socket 132 , the first plug tongue 131 with the overflow structure can be firmly combined with the first socket 132 and is not easy to slide out or bounce off, which can effectively improve the connection firmness between the contact plate 123 and the matching plate 214 .

[0079] When the side plate 11 and the buffer have a certain length in the first direction, in order to ensure that the triangular buffer space formed by the side plate 11 and the buffer is more solid and stable, the number of the matching components 13 formed by the first tongue 131 and the first socket 132 can be multiple and arranged in sequence along the first direction.

[0080] Of course, in some other embodiments, the structure of the buffer member 12 can be adaptively adjusted, such as by providing a fold line on the contact plate 123, so that the buffer space can present a quadrilateral or other structure in the first direction, as long as the buffer space finally formed still has a good buffering effect.

[0081] The buffer liner 10 provided in this embodiment is suitable for products that require buffer protection on only one side of the circumference.

[0082] In addition to the above-mentioned method, a new buffer liner 10 structure is provided in another embodiment of the present application. The connection between the buffer member 12 of the buffer liner 10 and the side panel 11 is more firmly connected, and the buffer space formed is more stable.

[0083] Specifically, a support plate 125 may be provided outside the free end of the buffer member 12 (ie, the free end of the contact plate 123 mentioned above), such as Figure 5 The support plate 125 can be connected to the buffer member 12 via the second bending line 126 and can be folded relative to the contact plate 123 into the buffer space to achieve a close connection with the side plate 11 .

[0084] The second bending line 126 is parallel to the first bending line 121 and extends along the first direction. That is, when the side panel 11 is a rectangular sheet structure, the second bending line 126 is parallel to the first bending line 121 and the first side edge 111.

[0085] In some embodiments, a fourth tongue 1251 is formed at the free end of the support plate 125 (i.e., the end of the support plate 125 away from the side panel 11 when the buffer liner 10 is in the unfolded state), and a fourth socket 101 matching with the fourth tongue 1251 is formed on the first side edge 111 adjacent to the support plate 125, and the size of the fourth tongue 1251 is not less than the size of the fourth socket 101; when the support plate 125 is in contact with the side panel 11, the fourth tongue 1251 can be inserted into the fourth socket 101.

[0086] Specifically, the structure of the fourth plug tongue 1251 is substantially the same as that of the first plug tongue 131, and is a limit block structure formed by the outward protrusion of part of the side edge of the free end of the support plate 125; the structure of the fourth socket 101 is substantially the same as that of the first socket 132, and is a strip hole structure. When the fourth plug tongue 1251 and the fourth socket 101 are plugged and connected, the support plate 125 can be attached to and firmly connected to the side plate 11, so as to further improve the firmness of the buffer space, so that it can still provide a good buffering and shock-absorbing effect for the product when squeezed by external force.

[0087] In some embodiments, the buffer liner 10 may further include a bottom plate 14 , in which case the side plate 11 has a connecting side edge 112 connecting the two first side edges 111 , and the side plate 11 is connected to the bottom plate 14 via the connecting side edge 112 and can be folded and moved relative to the bottom plate 14 .

[0088] When the side plate 11 is folded relative to the bottom plate 14 , the bottom plate 14 is located at one end of the side plate 11 in the first direction, which can provide certain limiting protection for the product in the first direction (ie, the axial direction of the product).

[0089] It should be noted that the number of the bottom plate 14 can be one or two. When the number of the bottom plate 14 is one, the structure of the buffer liner 10 is as follows: Figure 3-Figure 5 As shown; when the number of the bottom plates 14 is two, the two bottom plates 14 are respectively located at both ends of the side plate 11 in the first direction, which can provide better axial limiting protection for the product in the first direction after folding.

[0090] The structure of the buffer liner 10 is described below by taking the number of the bottom plate 14 as one as an example.

[0091] In some embodiments, a second socket 141 is provided on the bottom plate 14, and the second socket 141 is a strip-shaped hole. Part of the outer edge of the buffer 12 protrudes outward and forms a second plug tongue 124 that matches the second socket 141. The size of the second plug tongue 124 is not less than the size of the second socket 141; when the side plate 11 is folded relative to the bottom plate 14 until the buffer 12 and the bottom plate 14 are connected, the second plug tongue 124 can be inserted into the second socket 141.

[0092] Specifically, the second plug tongue 124 is a stopper block protruding outward relative to the outer edge of the buffer 12, and the second socket 141 is a strip-shaped hole. The second plug tongue 124 is generally formed on the side of the contact plate 123 close to the bottom plate 14. Of course, it can also be formed on the connecting plate 122 or formed on both the connecting plate 122 and the contact plate 123.

[0093] When the second tongue 124 is inserted into the second socket 141, the buffer 12 is detachably connected to the bottom plate 14. The bottom plate 14 can position and fix the contact plate 123 through the second socket 141, thereby further fixing the buffer 12 to help improve the structural strength of the buffer liner 10.

[0094] The structure of the folding paperboard with the above-mentioned support plate 125 and bottom plate 14 is as follows Figure 5 As shown, the folded paperboard can be formed by folding as shown in Figure 3 When folding the folded paperboard, the buffer member 12 can be folded relative to the side plate 11 by the first side edge 111, the first bending line 121 and the second bending line 126, as shown in FIG. Figure 4 As shown, the side panel 11 is then folded relative to the bottom panel 14 by connecting the side edges 112, and finally the following is obtained: Figure 3 The cushioning liner 10 is shown.

[0095] Of course, the cushioning liner 10 can also be unfolded to obtain the above-mentioned folding paperboard.

[0096] The buffer liner 10 provided in this embodiment is suitable for products that require buffer protection on only one side of the circumference.

[0097] When the buffer members 12 are arranged on the outer sides of the two first side edges 111 of the side plate 11, in order to ensure that the different buffer members 12 do not interfere with each other when connected to the side plate 11, and at the same time make the buffer lining 10 have a better buffering effect, in another embodiment of the present application, a new buffer lining 10 is also provided, such as Figure 6-Figure 8 As shown, the buffer lining 10 can provide a buffer lining 10 structure with better buffering effect at multiple circumferential angles of the product.

[0098] Specifically, the buffer liner 10 has a side plate 11 and a buffer member 12, wherein the two first side edges 111 of the side plate 11 are both arranged with the buffer member 12, and at least one first plug tongue 131 is formed on the contact plate 123 of any buffer member 12, and the first plug tongues 131 are staggered in the first direction, and the first sockets 132 matched with the first plug tongues 131 are formed in the middle of the side plate 11 and are arranged in sequence along the first direction to respectively match with the first plug tongues 131 at different positions in the first direction.

[0099] It should be noted that the projections of the buffer members 12 formed on both sides of the side plate 11 in the second direction in the first direction are connected or partially overlapped, such as Figure 6 As shown, the product requiring buffering protection is prevented from directly contacting the middle of the side plate 11.

[0100] In some cases, there are two contact plates 123 connected to the same side plate 11 with different numbers of first plug tongues 131, such as Figure 7 and Figure 8 As shown. Figure 7 and Figure 8 In the embodiment, contact plates 123 are provided on both sides of the side plate 11, one of the contact plates 123 is provided with a first plug tongue 131, and the other contact plate 123 is provided with two first plug tongues 131. Accordingly, three first sockets 132 arranged at intervals along the first direction are formed in the middle of the side plate 11.

[0101] Of course, when the size of the side panel 11 in the first direction is relatively large, at this time, at least two buffer members 12 may be provided on a first side edge 111 of the side panel 11, and the numbers of the first inserting tongues 131 on the two buffer members 12 may be different. The number and distribution positions of the first inserting tongues 131 on a buffer member 12 may be adaptively adjusted according to actual packaging and transportation needs, and will not be described in detail here.

[0102] In this embodiment, a bottom plate 14 connected to the side plate 11 may be provided as required.

[0103] The buffer liner 10 provided in this embodiment can provide buffer protection for part of the side wall of the product in the circumferential direction.

[0104] In another embodiment of the present application, a buffer liner 10 is provided that can provide circumferential and all-round protection for the product.

[0105] Specifically, the buffer liner 10 comprises a side plate 11 , a buffer member 12 and a bottom plate 14 , wherein the number of the side plates 11 is at least two and they are arranged at intervals along the outer peripheral edge of the bottom plate 14 .

[0106] Taking the bottom plate 14 as a rectangular plate structure as an example, in this case, the number of the side plates 11 is two and they are arranged on two opposite sides of the bottom plate 14, respectively. Figure 9-12 If the bottom plate 14 is a regular hexagonal plate structure, then the number of the side plates 11 is three and they are arranged at intervals on the three side walls of the bottom plate 14. The number of the side plates 11 can be adaptively adjusted according to the packaging requirements and the shape of the bottom plate 14.

[0107] The structure of the buffer liner 10 provided in this embodiment is specifically described below by taking the bottom plate 14 as a rectangle as an example. Figure 9-12 shown.

[0108] The buffers 12 respectively arranged on two different side panels 11 will contact each other. In order to connect the buffers 12 and form a stable structure, in some embodiments, the buffer liner 10 further includes a plug-in component 15 for connecting two adjacent side panels 11. The plug-in component 15 includes a third plug-in tongue 151 and a third socket 152 that cooperate with each other, wherein the third plug-in tongue 151 and the third socket 152 are respectively constructed on two different buffers 12 that are folded and attached to each other, and the size of the third plug-in tongue 151 is not less than the size of the third plug-in tongue 151; when the two adjacent side panels 11 are folded relative to the bottom plate 14 to connect the two buffers 12 located on different side panels 11, the third plug-in tongue 151 is inserted into the third socket 152, thereby realizing a stable connection of the two connected buffers 12.

[0109] Specifically, a third socket 152 is formed on a certain buffer 12 formed on a certain side plate 11, and the third socket 152 is a bar-shaped hole; a third plug tongue 151 that matches the third socket 152 is formed at a corresponding position of the buffer 12 formed on the other side plate 11 opposite to the buffer 12. When the two side plates 11 are folded relative to the bottom plate 14 and the two buffers 12 are in contact, the third plug tongue 151 can be inserted into the third plug block, and the two side plates 11 are connected through the third plug tongue 151 and the third socket 152.

[0110] Specifically, the third plug tongue 151 is a limit block protruding toward the side facing away from the side plate 11, and the third socket 152 is a bar-shaped hole matched with the third plug tongue 151. Fig. 9 and Fig.10 shown.

[0111] Since the two buffer members 12 are in contact with each other through the first bending line 121 when they are connected, any one of the third inserting tongue 151 and the third inserting hole 152 can be formed at the corresponding first bending line 121. Fig.11 and Fig.12 shown.

[0112] Specifically, the third tongue 151 is a limit block formed by cutting along part of the first bending line 121, and the limit block protrudes toward the side facing away from the side plate 11. The third socket 152 is a strip hole formed on part of the first bending line 121 and matched with the third tongue 151. Either the third tongue 151 or the third socket 152 is extended along the first bending line 121.

[0113] In another embodiment of the present application, a buffer liner 10 is further provided, wherein a corner of at least one support plate 125 in the buffer liner 10 can be folded toward the buffer space, thereby providing certain support to the buffer space. Fig.13 shown.

[0114] It should be noted that the buffer liner 10 provided in this embodiment does not limit the number of side panels 11 and the shape of the bottom panel 14. The number of side panels 11 and the shape of the bottom panel 14 can be adjusted according to the shape of the product to be packaged and the packaging needs. As the number of side panels 11 changes, the size of the connecting plate 122 and the contact plate 123 in the corresponding buffer member 12 also needs to be adaptively adjusted to ensure that the buffer members 12 formed on different side panels 11 can be connected after folding, so as to maintain the structural stability of the buffer liner 10 and ensure that the buffer liner 10 finally assembled can meet the packaging and transportation requirements.

[0115] Compared with the related art, the buffer lining 10 structure provided in the above embodiments is made of cardboard and is more environmentally friendly. It can achieve buffer packaging for products and provide better buffering effect while reducing or even eliminating packaging such as pearl cotton and bubble bags.

[0116] The above are only several preferred embodiments of the buffer liner 10. In practical applications, those skilled in the art can flexibly design the buffer liner 10 as needed.

[0117] The present application also provides a folding cardboard, which is used to form the buffer liner 10 described in any one of the above items; in other words, the buffer liner 10 can be folded by the folding cardboard.

[0118] According to the folding cardboard of the embodiment of the present application, the folding cardboard can be folded to form the above-mentioned buffer lining 10 which has certain buffering performance and is relatively environmentally friendly, and the folding method is simple and convenient.

[0119] See also Figure 14-16The present application also provides a product package 100, including a cushioning liner 10 and a packaging box 20, wherein the cushioning liner 10 is any of the cushioning liner 10 described above, and the packaging box 20 is provided with a receiving cavity 201 for receiving the product, and the cushioning liner 10 is inserted into the receiving cavity 201 along a first direction to provide cushioning for the product.

[0120] According to the product packaging 100 provided in the embodiment of the present application, the product packaging 100 can form a buffer structure in the receiving cavity 201 of the packaging box 20 by using the buffer liner 10, thereby providing buffering for the product placed in the receiving cavity 201. With the cooperation of the buffer liner 10 and the inner wall of the packaging box 20, the buffering packaging of the relevant product is achieved.

[0121] It should be noted that before placing the product into the packaging box 20, it is necessary to select a cushioning liner 10 that meets the requirements based on the product's requirements for cushioning protection, and ensure that the cushioning liner 10 is facing the side of the product that requires cushioning protection.

[0122] In some embodiments, at least one end of the packaging box 20 in the first direction is provided with a limiting member 21 extending outward and capable of being folded and moved relative to the accommodating cavity 201, such as Fig.15 When the limiting member 21 is folded outward relative to the accommodating cavity 201, the accommodating cavity 201 can be relatively exposed, which facilitates the taking and placing of the buffer liner 10 and related products in the packaging box 20; when the limiting member 21 is folded inward relative to the accommodating cavity 201 to cover the accommodating cavity 201, the product placed in the packaging box 20 can be provided with axial limitation to prevent the product from moving relative to the packaging box 20 along the first direction (i.e., the axial direction of the product), thereby giving the product packaging 100 a better buffering and limiting effect.

[0123] In some embodiments, the limiting member 21 includes a limiting plate 211, an assembly plate 212 and an abutting plate 213. Fig.16 As shown, the assembly plate 212 is used to connect the limiting plate 211 and the packaging box 20, and the two abutment plates 213 are connected to the limiting plate 211 and are respectively located on both sides of the limiting plate 211 and are symmetrically arranged relative to the assembly plate 212. The abutment plates 213 and the assembly plate 212 are folded toward the same side of the limiting plate 211, so that when the limiting member 21 is folded into the accommodating cavity 201, the abutment plates 213 can abut against the side wall of the accommodating cavity 201.

[0124] The limiting member 21 can provide a certain horizontal support to the accommodating cavity 201 through the abutment plate 213, thereby improving the firmness of the combination between the limiting plate 211 and the side wall of the accommodating cavity 201, which can not only help improve the stability of the limiting member 21 in the packaging box 20, but also help improve the strength of the packaging box 20.

[0125] In order to facilitate the user to open the limit member 21 and take the product, in some embodiments, the end of the limit plate 211 away from the assembly plate 212 is at least partially recessed inward to form a yield portion 2111. When the limit member 21 is folded into the accommodating cavity 201, a yield space 202 is formed between the yield portion 2111 and the side wall of the accommodating cavity 201. The user can insert the hand into the above-mentioned yield space 202 and conveniently fold the limit member through the yield space 202 to take the product located in the accommodating cavity 201.

[0126] In some embodiments, the stopper 21 further includes a matching plate 214 connected to the stopper plate 211 by a yielding portion 2111, and the matching plate 214 is arranged opposite to the assembly plate 212. The matching plate 214 can be folded toward the same side of the stopper plate 211 as the assembly plate 212. When the stopper 21 is located in the accommodating cavity 201, the user can conveniently pull the stopper plate 211 to fold through the matching plate 214 to take out the product located in the accommodating cavity 201.

[0127] In some embodiments, the matching plate 214 is folded and connected to a side edge of the limiting plate 211 and its size is slightly smaller than the side edge, so that there is a gap between the matching plate 214 and the adjacent abutting plate 213. The gap exists when the limiting member 21 is in the unfolded state and the folded state.

[0128] In the folded state, the above gap can prevent the matching plate 214 from directly contacting the abutting plate 213 to avoid friction resistance between the two, so that the matching plate 214 can easily drive the limiting plate 211 to fold relative to the accommodating cavity 201 when pulled by external force.

[0129] Compared with the related art, the product packaging 100 provided in this embodiment can provide circumferential and axial buffering protection and limiting effects for the product inserted therein, avoid or reduce displacement of the product in the first direction, and improve the buffering protection and limiting effects for the product.

[0130] The above is only a preferred embodiment of the product packaging 100. In actual applications, those skilled in the art can flexibly design the packaging box 20 and the buffer liner 10 as needed.

[0131] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
