Abstract
A foam dispenser comprises a plastic bottle made of a flexible plastic having a bottle opening, a closure cap which seals the bottle opening and has a dispensing opening for a foam. The foam dispenser further has a foam-generating device for foaming a solution, the device including a chamber having at least one wall and at least one porous body which is arranged in the chamber, wherein the foam-generating device is arranged in the closure cap and is at least partially formed by the closure cap. The foam dispenser can be manufactured cost-effectively, since it is composed of only a few components. The arrangement of the liquid inlet and the air inlet enables good emptying of residues. The foam-generating device also makes it possible to generate foam from alcoholic solutions.
