[0039] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below with reference to the drawings and specific embodiments.
[0040] Embodiment one
[0041] The embodiment provides a porcelain dinner plate packaging box, like Figures 1-4As shown, the device includes an outer box 10 and a partitioned and fixed inner liner 20. The outer box 10 has a receiving cavity, an opening communicating with the receiving cavity, and a cover plate 111 for closing the opening. The partitioned and fixed inner liner 20 has at least three inner liner side plates 21, each inner liner side plate 21 being distributed around the perimeter of a porcelain plate set, the porcelain plate set including at least one porcelain plate stacked vertically. The inner liner side plates 21 are provided with slots 25 for holding the sides of the porcelain plate set. The external dimensions of the partitioned and fixed inner liner 20 are consistent with the internal dimensions of the receiving cavity. The circumferential edges of the porcelain plate sets held in each slot 25 are spaced apart from the corresponding side walls of the receiving cavity. The upper and lower ends of the porcelain plate sets held in each slot 25 are also spaced apart from the corresponding upper and lower walls of the receiving cavity.
[0042] By employing the combination of the outer box 10 and the partitioning and fixing liner 20, firstly, the partitioning and fixing liner 20 located inside the outer box 10 serves as the first safety protection device for the porcelain plate set within the outer box 10. Secondly, the liner 20 uses slots 25 on its inner side plate 21 to hold the porcelain plate set around its circumference, allowing it to be placed entirely into the outer box 10. Because the partitioning and fixing liner 20 has a partitioning shape around the porcelain plate set, a certain distance is maintained between the outer perimeter of the porcelain plate set and the inner wall of the outer box 10, forming a second safety protection for the porcelain plate set. Furthermore, the external dimensions of the partitioning and fixing liner 20 are consistent with the internal dimensions of the accommodating cavity, allowing the partitioning and fixing liner 20 to be placed stably within the accommodating cavity without shaking, providing good shock resistance. In summary, this achieves effective safety protection for the porcelain plate set, reduces damage to the porcelain plates, and improves protective performance.
[0043] Specifically, a porcelain plate set can be a single porcelain plate or multiple porcelain plates stacked on top of each other. When it is multiple porcelain plates stacked on top of each other, the slot 25 is positioned to hold the side edge of the entire set, and a flexible layer is placed between two adjacent porcelain plates to reduce the risk of collision damage between them.
