[0045] The present embodiment provides a cushioning inner liner for packaging a product 100, which has good cushioning performance, reduces the probability of damage to the product 100, and has high reliability.

[0046] As shown in Figures 1 to 4 The cushioning inner liner includes a bottom inner liner body 1 and a top inner liner body 2.

[0047] The bottom inner liner 1 and the top inner liner 2 are both one-piece detachable structures formed by folding corrugated paperboard, that is, the material of the bottom inner liner 1 and the material of the top inner liner 2 are both corrugated paper, so that the bottom inner liner 1 and the top inner liner 2 can be folded into a shape when in use and are detached into a sheet shape when not in use, facilitating transportation and storage.

[0048] As shown in Figure 1 and Figure 2 The bottom inner liner 1 has a bottom buffer cavity 11 and two groups of X-direction buffer cavities 12 arranged along the X-direction, and the top inner liner 2 has a top buffer cavity 21 and two groups of Y-direction buffer cavities 22 arranged along the Y-direction. The bottom inner liner 1 and the top inner liner 2 cooperate to form a containing space for containing the product 100, the product 100 is placed in the containing space, and the bottom buffer cavity 11 and the top buffer cavity 21 are used to buffer external forces received by the product 100 in the Z-direction, the two groups of X-direction buffer cavities 12 are used to buffer external forces received by the product 100 in the X-direction, and the two groups of Y-direction buffer cavities 22 are used to buffer external forces received by the product 100 in the Y-direction. It should be noted that the product 100 is located between the bottom buffer cavity 11 and the top buffer cavity 21 in the Z-direction, is located between the two groups of X-direction buffer cavities 12 in the X-direction, and is located between the two groups of Y-direction buffer cavities 22 in the Y-direction.

[0049] The bottom inner liner 1 has a bottom buffer cavity 11 and X-direction buffer cavities 12, and the top inner liner 2 has a top buffer cavity 21 and Y-direction buffer cavities 22. The product 100 is placed in the containing space formed by the cooperation of the bottom inner liner 1 and the top inner liner 2, and the bottom buffer cavity 11 is used to buffer external forces received by the bottom surface of the product 100, the top buffer cavity 21 is used to buffer external forces received by the top surface of the product 100, the two X-direction buffer cavities 12 can buffer external forces received by the two side surfaces of the product 100 in the X-direction, and the two Y-direction buffer cavities 22 can buffer external forces received by the two side surfaces of the product 100 in the Y-direction, thereby achieving all-around protection of the product 100. The design of the buffer cavities enables the bottom inner liner 1 and the top inner liner 2 to have a large deformation space, so that the protection of the product 100 by the multiple buffer cavities has a good protection effect, the probability of damage of the product 100 is reduced, and the reliability of protecting the product 100 is improved.

[0050] Optionally, the bottom inner liner 1 comprises a U-shaped main plate 13, a first bottom plate 14 and an inner liner side plate 15. The U-shaped main plate 13 is used to form a containing space. One end of the first bottom plate 14 is connected to the U-shaped main plate 13 in a fixed manner. The other end of the first bottom plate 14 is detachably connected to the U-shaped bottom 133 of the U-shaped main plate 13, and the first bottom plate 14 forms a bottom buffer cavity 11 outside the U-shaped main plate 13. Through the detachable connection between the first bottom plate 14 and the U-shaped main plate 13, the assembly and disassembly of the bottom inner liner 1 can be realized.

[0051] The U-shaped main plate 13 has two side portions 134 which are parallel to each other and perpendicular to the U-shaped bottom 133. The two side portions 134 of the U-shaped main plate 13 are respectively provided with the inner liner side plate 15. One end of the inner liner side plate 15 is connected to the corresponding side portion 134, and the other end is detachably connected to the corresponding side portion 134. The inner liner side plate 15 forms an X-direction buffer cavity 12 outside the U-shaped main plate 13. Through the detachable connection between the inner liner side plate 15 and the U-shaped main plate 13, the assembly and disassembly of the bottom inner liner 1 can be realized.

[0052] Further optionally, as shown in Figure 4 and Figure 5 , one of the first bottom plate 14 and the U-shaped bottom 133 of the U-shaped main plate 13 is provided with a first clamping groove 141, and the other is provided with a first clamping buckle 131 matched with the first clamping groove 141. The first clamping buckle 131 can be clamped into the first clamping groove 141 to realize the detachable connection between the other end of the first bottom plate 14 and the U-shaped bottom 133 of the U-shaped main plate 13.

[0053] Similarly, one of the inner liner side plate 15 and the side portion 134 of the U-shaped main plate 13 is provided with a second clamping groove 151, and the other is provided with a second clamping buckle 132 matched with the second clamping groove 151. The second clamping buckle 132 can be clamped into the second clamping groove 151 to realize the detachable connection between the other end of the inner liner side plate 15 and the side portion 134 of the U-shaped main plate 13. The clamping groove and the clamping buckle matched with each other have good connection effect and stability, and are easy to manufacture on corrugated paper, thereby improving the manufacturing efficiency of the bottom inner liner 1.

[0054] In some optional embodiments, as shown in Figure 5 , the first bottom plate 14 comprises a first plate portion 142, a second plate portion 143, a third plate portion 144 and a fourth plate portion 145 which are connected in sequence. The first plate portion 142 is connected to the edge of the U-shaped main plate 13 in the Y direction. The first clamping groove 141 or the first clamping buckle 131 is arranged on the fourth plate portion 145. The fourth plate portion 145 is detachably connected to the U-shaped bottom 133 of the U-shaped main plate 13 through the first clamping groove 141 or the first clamping buckle 131.

[0055] It should be noted that the first plate portion 142 and the U-shaped bottom portion 133, the first plate portion 142 and the second plate portion 143, the second plate portion 143 and the third plate portion 144, and the third plate portion 144 and the fourth plate portion 145 are provided with creases, so as to facilitate the folding assembly of the first bottom plate 14. Figure 5 The dashed lines in the figure represent creases.

[0056] It should also be noted that the U-shaped bottom portion 133 and the side portion 134 of the U-shaped main plate 13 are also provided with creases, so that the U-shaped main plate 13 can be folded.

[0057] In this embodiment, the first plate portion 142, the second plate portion 143, the third plate portion 144, and the fourth plate portion 145 are sequentially connected in a ring shape, thereby forming the bottom buffer cavity 11. In addition, the size of the second plate portion 143 in the X direction is smaller than the size of the U-shaped bottom portion 133 of the U-shaped main plate 13 in the X direction, and the two edges of the first plate portion 142 in the X direction are arc-shaped edges to connect the second plate portion 143 and the U-shaped main plate 13. By setting the size of the second plate portion 143 in the X direction to be smaller than the size of the U-shaped bottom portion 133 of the U-shaped main plate 13 in the X direction, when the buffer liner is folded from the disassembled state to the assembled state, the first bottom plate 14 and the liner side plate 15 do not interfere with each other, facilitating the folding assembly of the buffer liner.

[0058] Optionally, please continue to refer to Figure 5 The liner side plate 15 includes a fifth plate portion 152, a sixth plate portion 153, a seventh plate portion 154, and an eighth plate portion 155 connected in sequence. The fifth plate portion 152 is connected to the corresponding side portion 134 of the U-shaped main plate 13, specifically connected to the edge of the side portion 134 in the Y direction, and the second clamping groove 151 or the second buckle 132 is arranged on the eighth plate portion 155, so as to realize the detachable connection of the eighth plate portion 155 with the side portion 134 of the U-shaped main plate 13 through the second clamping groove 151 or the second buckle 132. It should be noted that the fifth plate portion 152 and the corresponding side portion 134, the fifth plate portion 152 and the sixth plate portion 153, the sixth plate portion 153 and the seventh plate portion 154, and the seventh plate portion 154 and the eighth plate portion 155 all have creases, so as to facilitate the folding assembly of the liner side plate 15.

[0059] In this embodiment, the fifth plate portion 152, the sixth plate portion 153, the seventh plate portion 154, and the eighth plate portion 155 are sequentially connected in a ring shape, thereby forming the X-direction buffer cavity 12.

[0060] Optionally, the first buckle 131 and the second buckle 132 are arranged on the U-shaped main plate 13, more specifically, the first buckle 131 is arranged on the U-shaped bottom portion 133 of the U-shaped main plate 13, and the second buckle 132 is arranged on the side portion 134 of the U-shaped main plate 13. And, as Figure 5As shown, the first clasp 131 and the second clasp 132 are provided with a crease between the U-shaped main plate 13, that is, the first clasp 131 has a crease between the U-shaped bottom 133, so that the first clasp 131 can be folded along the crease relative to the U-shaped bottom 133; the second clasp 132 has a crease between the side portion 134, so that the second clasp 132 can be folded along the crease relative to the side portion 134. The first clamping groove 141 is arranged on the first bottom plate 14, and the second clamping groove 151 is arranged on the inner lining side plate 15.

[0061] The shapes of the first clamping groove 141, the first clasp 131, the second clamping groove 151 and the second clasp 132 can be circular, polygonal, circular, etc., which are not limited in the embodiment, and are exemplarily shown as Figure 4 and Figure 5 As shown, the shapes of the first clamping groove 141, the first clasp 131, the second clamping groove 151 and the second clasp 132 in the embodiment are circular, so as to have better clamping effect.

[0062] Optionally, as shown in Figure 2 The first bottom plate 14 is provided with two, and the two first bottom plates 14 are respectively connected to the two ends of the U-shaped main plate 13 in the Y direction, and two bottom buffer cavities 11 are formed outside the U-shaped bottom 133 of the first bottom plate 14. By providing two bottom buffer cavities 11, better buffering effect and better supporting effect can be achieved. It should be noted that the outside of the U-shaped bottom 133 is the side of the U-shaped bottom 133 away from the side portion 134. It should be further noted that the bottom buffer cavity 11 in the embodiment is in the shape of a rectangular parallelepiped and extends along the X direction. In addition, the first clasp 131 and the first clamping groove 141 are correspondingly provided with a plurality of first clamping grooves 141, and the plurality of first clamping grooves 141 are arranged on the fourth plate portion 145 of the bottom buffer cavity 11.

[0063] Please refer to Figure 4 and Figure 5 Each side portion 134 of the U-shaped main plate 13 corresponds to two inner lining side plates 15, and the two inner lining side plates 15 are respectively connected to the two ends of the side portion 134 in the Y direction, and two X-direction buffer cavities 12 are formed on the surface of the side portion 134 away from the other side portion 134. By providing two X-direction buffer cavities 12 on each side portion 134, the buffering effect and supporting effect in the X direction can be improved, thereby improving the effect of protecting the product 100. In some optional embodiments, the X-direction buffer cavity 12 is square, and more specifically, the shapes of the sixth plate portion 153 and the eighth plate portion 155 are square.

[0064] As shown in Figure 3 and Figure 12As shown, the top inner liner 2 has the same structure as the bottom inner liner 1, and the difference is that the sizes can be different. Also, the U-shaped opening of the top inner liner 2 faces the bottom inner liner 1, and the extension direction of the top inner liner 2 is perpendicular to the extension direction of the bottom inner liner 1, thereby being able to cooperate with the bottom inner liner 1 to form a containing space. By setting the structures of the top inner liner 2 and the bottom inner liner 1 to be the same, the batch manufacturing of the top inner liner 2 and the bottom inner liner 1 can be facilitated, and there is no need to redesign. Also, the top inner liner 2 is in a reverse buckle shape and opposite to the extension direction of the bottom inner liner 1, which facilitates protecting the product 100 from the top, bottom, left, right, front, and back, and has a higher protection effect.

[0065] In this embodiment, as shown in Figure 3 The at least part of the top inner liner 2 can be located in the bottom inner liner 1 to wrap the product 100 in all directions.

[0066] When folding the Figure 5 corrugated paper shown in FIG. 10A into the Figure 1 bottom inner liner 1 shown in FIG. 10B, it is necessary to fold the U-shaped main plate 13, the X-direction buffer cavity 12, and the bottom buffer cavity 11 respectively. The sequence of forming the U-shaped main plate 13, the X-direction buffer cavity 12, and the bottom buffer cavity 11 is not limited in this embodiment, and can be selected as needed. This embodiment takes the example of first forming the U-shaped bottom 133 buffer cavity, then forming the X-direction buffer cavity 12, and finally forming the U-shaped main plate 13 for description.

[0067] When forming the U-shaped bottom 133 buffer cavity, the fifth plate portion 152 is folded 90° toward the back surface of the U-shaped bottom 133 along the crease line between the fifth plate portion 152 and the U-shaped bottom 133, then the sixth plate portion 153 is folded 90° along the crease line between the fifth plate portion 152 and the sixth plate portion 153, the seventh plate portion 154 is folded 90° along the crease line between the sixth plate portion 153 and the seventh plate portion 154, and the eighth plate portion 155 is folded 90° along the crease line between the seventh plate portion 154 and the eighth plate portion 155. The folding directions of the fifth plate portion 152, the sixth plate portion 153, the seventh plate portion 154, and the eighth plate portion 155 are the same, so that the eighth plate portion 155 can be attached to the back surface of the U-shaped bottom 133 after being folded, and finally the first clasp 131 of the U-shaped bottom 133 is clamped into the first clamping groove 141 of the eighth plate portion 155 to form the bottom buffer cavity 11.

[0068] In the forming of the X-direction buffer cavity 12, the first plate portion 142 is folded 90° along the crease line between the first plate portion 142 and the side portion 134 towards the back surface of the side portion 134, then the second plate portion 143 is folded 90° along the crease line between the first plate portion 142 and the second plate portion 143, the third plate portion 144 is folded 90° along the crease line between the second plate portion 143 and the third plate portion 144, and the fourth plate portion 145 is folded 90° along the crease line between the third plate portion 144 and the fourth plate portion 145, the folding directions of the first plate portion 142, the second plate portion 143, the third plate portion 144 and the fourth plate portion 145 are the same, so that the fourth plate portion 145 can be attached to the back surface of the side portion 134 after being folded, and finally the second buckle 132 of the side portion 134 is buckled into the second buckle slot 151 of the fourth plate portion 145 to form the X-direction buffer cavity 12.

[0069] After the forming of the two bottom buffer cavities and the four X-direction buffer cavities 12, each side portion 134 is folded 90° along the crease line between the U-shaped bottom portion 133 and the side portion 134 towards the front surface of the U-shaped bottom portion 133 to form a U-shaped main plate 13, and at the same time, the bottom inner liner 1 shown in Figure 1 or Figure 2 is formed.

[0070] The folding and assembling method of the top inner liner 2 can refer to the folding and assembling method of the bottom inner liner 1, which is not described herein.

[0071] The embodiment also provides a packaging box, as shown in Figures 6 to 12 , which comprises the inner liner partition 10 for covering the product 100 and the above-mentioned buffer inner liner.

[0072] The inner liner partition 10 is arranged in the accommodation space, so that the bottom buffer cavity 11, the X-direction buffer cavity 12, the Y-direction buffer cavity 22 and the top buffer cavity 21 of the buffer inner liner can protect the inner liner partition 10 and the product 100 located therein. By arranging the inner liner partition 10, the pre-packaging of the product 100 composed of multiple components can be achieved.

[0073] In the embodiment, the outer wall of the inner liner partition 10 corresponds to and abuts against the bottom inner liner 1 and the top inner liner 2, so that there is a small gap between the inner liner partition 10 and the bottom inner liner 1 and the top inner liner 2, thereby avoiding the collision between the inner liner partition 10 and the bottom inner liner 1 or the top inner liner 2, and further reducing the probability of damaging the product 100.
