A cartridge system for delivering an aqueous solution made with a mixture of an active material and a liquid medium, where the cartridge system includes a bottle-shaped container and a pump fastened to a neck of the container, where the container is filled with the liquid medium. The container includes a cartridge and an intake tube of the pump sealingly inserted in an upper side of the cartridge, where the active material is supplied to the cartridge through the intake tube. The cartridge is sealed from an exterior by a piston or a stopper, where the piston or stopper is movably arranged in a wall of the cartridge and configured to enter into an interior of the cartridge under reduced pressure produced by the pump and opens to the exterior of the cartridge so that the active material is mixable with the liquid medium.
