A packaging box and its packaging carton

Abstract

This utility model discloses a packaging box and its packaging case. The packaging box includes: a box body with a first receiving portion; and a lid rotatably connected to the other side of the box body, with a second receiving portion corresponding to the first receiving portion. When the lid is rotated to the position where it closes with the box body, the first and second receiving portions together form a receiving space for housing a tire pressure sensor. Through this method, when the lid is closed on the box body, the first and second receiving portions cooperate to form a receiving space, allowing the tire pressure sensor to be stably placed within it, preventing damage to the tire pressure sensor during transportation due to shaking, collisions, or other external forces, thus improving the integrity rate of the tire pressure sensor. Simultaneously, the rotatable connection between the lid and the box body makes the opening and closing process of the packaging box simple and quick, facilitating packaging and unpacking for users.
