The invention discloses a coating liquid bottle plug for preventing backflow, and a packaging bottle. The coating liquid bottle plug is characterized in that the coating liquid bottle plug is composedof a bottle cap, a bottle plug body and a bottle body; the bottle plug is embedded into the inner wall of a bottleneck of the bottle body for tight connection, the edge of a first face plate in the bottle plug body is in covering fit with the surface of the bottleneck of the bottle body, and the bottle cap is connected to the bottleneck of the bottle body; the bottle plug body is connected with the first face plate, a connecting pipe and a second face plate from top to bottom; the surface of the first face plate is of a net-shaped face structure or is provided with one or more first through holes; the surface of the second face plate is provided with one or more second through holes; protruded backflow-preventing pipes are arranged on the positions, at the circles of the edges of the second through holes, of the face, connected with the connecting pipe, of the second face plate, and the inner diameter of the backflow-preventing pipes is equal to or smaller than the inner diameter of the second through holes; and both the backflow-preventing pipes and the connecting pipe are hollow pipes. In this way, resources are saved, waste is reduced, and the coating liquid bottle plug is simple in structure, clean, sanitary and convenient to use.
Description
technical field [0001] The present invention relates to bottle stoppers, and more particularly to bottle stoppers for the application of liquids. Background technique [0002] The existing bottle stopper is provided with a through hole on the surface, which is used to prevent the liquid from flowing out too much and to smear the liquid. The structure is simple and the use is convenient. However, the liquid after smearing easily flows back into the bottle to pollute the liquid in the bottle. Use a cotton swab to apply, the cotton on the head of the swab will absorb a large amount of liquid, resulting in waste. Contents of the invention [0003] Provide a liquid coating stopper and packaging bottle that prevents backflow. Through the double-layer panel structure, the second panel is used to drip liquid and prevent liquid backflow, and the first panel is used to apply liquid and use tension to accumulate liquid. After breaking the tension The liquid is completely released,...
