Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a liquid application container.
[0002]
[Prior art]
Conventionally, a liquid application container is generally used as a container for applying a chemical solution to a part of the body, but recently, it is also used when applying a detergent or the like to a wall surface of a house. Many such liquid application containers have been known in the past, but the application stopper is usually fitted into the container neck and neck, and the liquid absorption material possessed by the application stopper by inversion or inclination of the container body. The liquid in the container is supplied and applied by rubbing the application surface. After the application is completed, the cap is fitted to the container neck.
[0003]
[Problems to be solved by the invention]
In the conventional liquid application container, the container body and the liquid absorption member of the application stopper that stands up with the lower part fitted to the container body neck and neck portion communicate with each other even when the cap is fitted. If the surface of the liquid-absorbing member falls down, the liquid contained in the liquid-absorbing member becomes too much. Therefore, when the rubbing surface formed on the upper surface of the liquid-absorbing member is rubbed against the surface to be coated, there is a drawback that the liquid is dripped due to too much liquid being applied.
[0004]
In the present invention, when the container body is capped, the application stopper base portion with the liquid absorbing member is pushed into the container body mouth / neck, thereby blocking the liquid passage to the liquid absorbing member and containing the liquid in the liquid absorbing member. When the cap is removed, the application plug is pushed out of the mouth and neck, and the liquid passage is opened. Is provided. The coil spring for biasing the coating plug was provided so as not to adversely affect the liquid.
