Abstract
The soap solution dispenser contains a reservoir into which opens an outlet or outflow opening of a container. In the reservoir there is present a float body or float which is pivotably mounted and provided with at least one indicator flag. Conjointly with the drop of the liquid level in the soap solution reservoir the float body also descends, which causes a displacement of the indicator flag. During the lowering of the surface of the soap solution the indicator flag moves along a viewing window formed in a cover or covering hood. There is thus signalled or indicated that the content of the soap solution in the reservoir is quite small or nearly consumed, so that the container now should be exchanged. One resulting advantage of the invention is that the indicator flag moves externally of the soap solution, so that the indicator flag cannot become stuck or bind, and thus, always remains readily visible.
