Its unfolded structure is as follows: Figure 2 As shown, the structure includes a lower buffer plate 1-1, a lower horizontal support plate 1-2, a lower side plate 1-3, a lower positioning plate 1-4, and a lower side plate 1-9, which are folded and connected in sequence. After folding, the lower horizontal support plate 1-2 lies flat on top of the lower buffer plate 1-1. The bottle body fixing cavity is formed by folding the lower horizontal support plate 1-2, the lower side plate 1-3, the lower positioning plate 1-4, and the lower side plate 1-9 to form a cuboid structure. The lower horizontal support plate 1-2 forms the bottom surface, the lower side plate 1-3 and the lower side plate 1-9 form two opposite sides, and the lower positioning plate 1-4 forms the top surface. The lower positioning plate 1-4 has several upper limit holes 1-5, which are adapted to fit the bottle body and are used to fix the bottle body. After the bottle body is placed into the bottle body fixing cavity through the upper limit holes 1-5, the bottom of the bottle contacts the lower horizontal support plate 1-2, thereby limiting the position of the bottle body.

[0038] The upper pad 2 is formed by folding a piece of paper. The fold lines of the upper pad 2 are all aligned with the corrugated direction. Its unfolded structure is as follows: Figure 4 As shown, it includes an upper buffer plate 2-1, an upper horizontal support plate 2-2, and an upper positioning plate 2-3 connected in sequence by folding. After folding, the upper buffer plate 2-1 is laid flat on the upper horizontal support plate 2-2. The neck fixing cavity is formed by folding the upper horizontal support plate 2-2 and the upper positioning plate 2-3. The upper positioning plate 2-3 has a folding line along the corrugated direction, which allows it to be folded into a V-shaped structure. The upper horizontal support plate 2-2 is located at the top of the V-shaped structure. Several elliptical openings are also provided in the V-shaped groove to form an upper limit hole 2-4. The shape and size of the upper limit hole 2-4 must be adapted to the shape of the bottle being held, so as to lock the upper part of the bottle and the shoulder of the bottle and prevent the upper part of the bottle from shaking.

The side of the lower buffer plate 1-1 away from the lower horizontal support plate 1-2 is provided with a tongue two 1-72.

[0046] In use, the lower buffer plate 1-1 is folded into a zigzag shape along the folding line to form a buffer layer, and the tongue two 1-72 is inserted into the tongue hole two 1-82. At this time, the lower horizontal support plate 1-2 is folded and laid on the buffer layer along the folding line, and then the lower side plate one 1-3, the lower positioning plate 1-4 and the lower side plate two 1-9 are folded along the folding line with the lower horizontal support plate 1-2 as the bottom surface of a cuboid. After folding, a cuboid structure is formed above the lower horizontal support plate 1-2, and the tongue one 1-71 is inserted into the tongue hole one 1-81 to fix the cuboid structure. The tongue can be inserted from the long ladder-shaped opening first, and then locked through the short ladder-shaped opening, so that the lower buffer plate 1-1, the lower horizontal support plate 1-2 and the lower positioning plate 1-4 are firmly combined into the lower gasket 1, as shown in Figure 3 .

[0047] The folding line connection between the upper horizontal support plate 2-2 and the upper buffer plate 2-1 is provided with a tongue hole four 2-62, and the folding line connection between the upper horizontal support plate 2-2 and the upper positioning plate 2-3 is provided with a tongue hole three 2-61. The tongue hole four 2-62 and the tongue hole three 2-61 are both ladder-shaped and have different lengths. The side of the upper buffer plate 2-1 away from the upper horizontal support plate 2-2 is provided with a tongue three 2-51 matched with the tongue hole three 2-61. The side of the upper positioning plate 2-3 away from the upper horizontal support plate 2-2 is provided with a tongue four 2-52 matched with the tongue hole four 2-62.

[0048] In use, the upper buffer plate 2-1 is folded into a zigzag shape along the folding line to form a buffer layer, and the plug tongue three 2-51 is inserted into the plug hole three 2-61. At this time, the upper horizontal support plate 2-2 is folded and laid flat under the buffer layer along the folding line, and then the upper positioning plate 2-3 is folded into a V shape under the upper horizontal support plate 2-2. The plug tongue four 2-52 is inserted into the plug hole four 2-62. The plug tongue can be inserted from the long ladder-shaped opening first, and then locked through the short ladder-shaped opening, so that the upper buffer plate 2-1, the upper horizontal support plate 2-2 and the upper positioning plate 2-3 are firmly combined into the upper gasket 2, as shown in Figure 5

[0049] Example 5

[0050] On the basis of example 4, in this embodiment, a plurality of diamond-shaped openings are formed in the folding line connection between the lower positioning plate 1-4 and the lower side plate one 1-3 and the lower side plate two 1-9, forming an upper gasket positioning groove 1-6. In the unfolded structure of the lower gasket 1, the upper gasket positioning groove 1-6 is arranged in a column, and the number of the upper gasket positioning groove 1-6 is the same as the number of the lower limiting hole 1-5 in the V-shaped structure of the lower positioning plate 1-4. The line of each column of the upper gasket positioning groove 1-6 is perpendicular to the folding line, and at the same time, passes through the center of the lower limiting hole 1-5. In use, the V-shaped groove of the upper gasket 2 is embedded in the upper gasket positioning groove 1-6, which can prevent the relative displacement of the upper gasket 2 and the lower gasket.

[0051] In actual use, the side with the buffer layer of the lower gasket 1 faces downward, and the side with the buffer layer of the upper gasket 2 faces upward. First, the lower gasket 1 is placed in the express box, then the fragile bottle is placed in the bottle body fixing cavity through the lower limiting hole 1-5, the bottle bottom falls on the lower horizontal support plate 1-2, and the bottle body is clamped in the lower limiting hole 1-5. Subsequently, the upper gasket 2 is positioned by aligning the upper limiting hole 2-4 with the bottle neck, so that the upper half of the bottle is clamped in the upper limiting hole 2-4, and the V-shaped groove of the upper positioning plate 2-3 is embedded in the upper gasket positioning groove 1-6, which can avoid the relative sliding and displacement of the upper and lower gaskets during transportation. At the same time, the bottle mouth is pressed against the upper horizontal support plate 2-2 of the upper gasket 2, so that the bottle is stably placed between the upper and lower gaskets. After the upper and lower gaskets are placed, the folding line direction of the lower gasket 1 is perpendicular to the folding line direction of the upper gasket 2. This cross support structure can better resist the impact force from the four sides of the box, improving the stability of the overall structure. Due to its stable structure and good pressure resistance, it can be safely stacked in multiple layers during transportation and storage. This not only improves the space utilization, but also further optimizes the efficiency and safety of express transportation, reducing the risk of damage to goods caused by improper stacking.
