Dosing container for a liquid washing lye additive

The invention relates to a dosing container (1) for a liquid washing lye additive. Said container comprises a receiving chamber (2) to receive the additive, a closeable feed opening (3), and a plurality of discharge outlets (4) whereby said additive is discharged from the dosing container into the washing lye (1) during the washing process. The inventive container is especially suitable for adding a washing lye additive to the washing lye in that it also comprises a pre-mix chamber (5); the discharge outlets (4) are arranged in the wall (6) of the pre-mix chamber (5); and the receiving chamber (2) is hydraulically connected to the pre-mix chamber in such a way that a washing lye additive in the receiving chamber (2) is slowly mixed in a substantially continuous manner with the washing lye which flows through the pre-mix chamber (5). The invention especially relates to an elasticoviscous washing lye additive, especially a bleaching and disinfectant agent.
