The utility model relates to a hasp and discloses a special flat mouth hasp capable of being locked safely, which comprises a base and a rotating seat, one end of the rotating seat is connected with a child hasp, the child hasp can be buckled on a female hasp, one end of the rotating seat is rotatably connected with the base, and the base is provided with a moving hasp. When the utility model is used, the female hasp can be installed on the box cover of special equipment, the base is installed on the box body, the child hasp is buckled on the female hasp, the child hasp can be clamped together with the female hasp after the rotating seat is rotated by a set angle, the box cover and the box body cannot be separated, meanwhile, the utility model is provided with the moving hasp, the rotating seat and the base can be clamped by the moving hasp, the rotating seat and the base cannot be separated automatically, and the safety of objects in the box body can be ensured. When the rotating seat and the base are separated, the moving hasp is pushed upwards, the moving hasp cannot clamp the base, the child hasp can be separated from the female hasp after the rotating seat is rotated by a set angle, and therefore the box cover can be opened.

This utility model discloses a packaging box in the field of product packaging technology. The packaging box includes a box body with a top plate, a bottom plate, and multiple side plates. The top plate, bottom plate, and side plates together form an accommodating space for placing bottles. Adjacent side plates are connected by hinges. Only one side plate is fixedly connected to the top plate at its upper end and to the bottom plate at its lower end. The side plate fixedly connected to the top and bottom plates is a fixed side plate, while the other side plates are movable side plates, which can rotate to be coplanar with the first side plate. The box body has at least a first state and a second state. In the first state, the top plate, bottom plate, and side plates together form the accommodating space; in the second state, the multiple side plates are coplanar. The multiple side plates can be unfolded into a flat surface. When the side plates are unfolded, it is convenient to place and retrieve the bottles, and the unfolded side plates can serve as a background wall, providing more interactive display effects in conjunction with the bottles.

The present application provides an opening device for a container, the opening device comprising a base, a cap and a cap seat. The base comprises a neck defining a first rotational ascending trajectory and a second rotational ascending trajectory about an axis X. The cap is configured to be able to make a rotational ascending movement along the first ascending rotational trajectory. The cap seat is configured to be able to make a rotational ascending movement along the second rotational ascending trajectory. The cap and the cap seat are configured to be able to rotate together such that when the cap seat is rotated ascendingly from a cap seat initial position to a cap seat end position, the cap is rotated ascendingly from a cap initial position to a cap end position.

This utility model discloses a color sample storage tray, relating to the field of printing equipment technology. It includes a storage component with several storage units disposed inside. Each storage unit includes a placement base, a rotating base at one end of the placement base, and a hinged base connecting the placement base and the rotating base. A connecting base is rotatably connected to one side of the rotating base. A placement groove is formed on the upper surface of the placement base, and a limiting component is disposed inside the placement groove. A sample is slidably disposed inside the placement groove. This utility model, through its modular storage component design and the linkage design of the rotating column and the connecting base, supports the simultaneous unfolding of multiple samples, improving comparison efficiency. Furthermore, the angle of the samples can be adjusted, allowing users to compare colors from multiple angles without completely removing the samples, significantly improving operational convenience.
