  • Patent number: 9650739
    Abstract: Gradual-release dosing device for at least one substance in a domestic-use apparatus comprises the presence of a water based work fluid, characterized in that it comprises a casing (2) within which a plurality of doses of said substances (3) is contained, necessary for the corresponding plurality of operation cycles of said apparatus. Said casing (2) being at least partly defined by a material perrreable to said work fluid and capable of releasing at least a dose of said substance (3) at each operation cycle of the apparatus. The substance comprises at least one washing-active, dishwashing-active or cleaning-active preparation from the group consisting of surfactants, builders, water softening agents, zeolites, silicates, polymers, carbonates, carboxylates, sulphonates, bleaching agents, bleach activators, bleach stabilizers, bleach catalysts, cobuilders, alkalizing agents, acidifying agents, redeposition inhibitors, dyes, fragrances, optical is brighteners, UV filters, fabric softeners, and rinse agents.
