[0025] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0026] Please refer to Figures 1 to 3 In a preferred embodiment, the new slot-type lining of the utility model includes a bottom plate 1, both ends of the bottom plate 1 are bent to form vertical portions 2, one vertical portion 2 is bent toward the other vertical portion 2 to form a first inclined portion 3, the first inclined portion 3 is bent in the opposite direction to form a second inclined portion 4, the end of the second inclined portion 4 is bent to form a supporting portion 5, the first inclined portion 3 and the second inclined portion 4 both form an angle with the horizontal direction, the supporting portion 5 is against the bottom plate 1, and a through hole is provided at the connection between the first inclined portion 3 and the second inclined portion 4, the through hole is formed into a half groove 6 by bending, and the two half grooves 6 are relatively formed to form a positioning groove 7 for fixing the product.

[0027] For example, the novel card slot lining of the present invention can be made of existing cardboard such as single-corrugated cardboard, double-corrugated cardboard, triple-corrugated cardboard, and hardboard. The two ends of the bottom plate 1 are bent to form vertical portions 2, and the vertical portions 2 are formed to be perpendicular to the bottom plate 1. One end of the vertical portion 2 is away from the bottom plate 1 and is bent toward the other vertical portion 2 to form a first inclined portion 3 extending obliquely downward. The end of the first inclined portion 3 is bent toward the vertical portion 2 on the same side as the first inclined portion 3 to form a second inclined portion 4. The second inclined portion 4 extends obliquely downward and then bends in the opposite direction toward the vertical portion 2 on the other side to form a support portion 5. During specific production, pre-creases can be set between the bottom plate 1 and the vertical portion 2, between the vertical portion 2 and the first inclined portion 3, between the first inclined portion 3 and the second inclined portion 4, and between the second inclined portion 4 and the support portion 5 to facilitate bending during packaging.

[0028] As can be seen from the above technical solution, by bending the two ends of a single bottom plate 1, a lining structure for fixing the product can be formed, eliminating the need to splice or plug multiple cardboards, effectively simplifying the packaging operation and improving packaging efficiency. During specific packaging, the vertical portion 2, the first inclined portion 3, the second inclined portion 4, and the support portion 5 are formed in sequence by bending. The first inclined portion 3 and the second inclined portion 4 on the same side are bent to form a half groove 6, which cooperates with the half groove 6 on the other side to form a complete positioning groove 7. The product can be placed in the positioning groove 7. The first inclined portion 3, the second inclined portion 4, and the vertical portion 2 cooperate to form a triangular stable support structure to position the periphery of the product. The support portion 5 can support the bottom of the product. The overall structure is stable and has a good protective effect.

[0029] In this embodiment, the vertical portion 2, the first inclined portion 3, the second inclined portion 4, and the support portion 5 are all symmetrically arranged about the center line of the bottom plate 1. The symmetrical structure can make the overall structure more stable and further improve the protection effect of the product.

[0030] In this embodiment, bent portions 8 are formed on both sides of the half groove 6, wherein the bent portion 8 of one half groove 6 is adjacent to or abuts against the bent portion 8 of the other half groove 6. For example, after the first inclined portion 3 and the second inclined portion 4 are bent, bent portions 8 are formed at the connection points on both sides of the half groove 6 in the horizontal direction. The bent portions 8 protrude from the half groove 6 and are adjacent to or abut against the bent portion 8 of the other half groove 6, thereby reducing the movable space of the structures on both sides, improving the stability of the structure, and preventing the overall structure from being deformed by external forces.

[0031] In this embodiment, the ends of the two supporting parts 5 are adjacent to or abut against each other, and can cooperate to form a supporting surface for supporting the product, thereby protecting the bottom of the product.

[0032] The half groove 6 includes a first groove wall 9 located on the first inclined portion 3 and a second groove wall 10 located on the second inclined portion 4. The first groove wall 9 and the second groove wall 10 are respectively adapted to abut against the upper and lower ends of the product. The first groove wall 9 and the second groove wall 10 can respectively limit the upper and lower ends of the product, thereby maintaining the product's height stability and improving the protective effect.

[0033] A glue layer is provided between the support portion 5 and the bottom plate 1 . By gluing the support portion 5 and the bottom plate 1 together, the strength of the structure can be further improved, making the structure more stable.

[0034] In this embodiment, the angle between the first inclined portion 3 and the horizontal direction is equal to the angle between the second inclined portion 4 and the horizontal direction, thereby improving the stability of the structure.

[0035] The utility model also provides a packaging box, comprising a box body and the novel card slot type liner as described above, wherein the novel card slot type liner is arranged in the box body.
