Abstract
An apparatus for holding and dispensing metered doses of at least one active composition in a washing machine, a dryer or a dishwasher has at least two separate compartments for respectively receiving and dispensing an active composition and an opening mechanism for the compartments, which is operated by means which are activated by conditions prevailing in the inside of the machine. These conditions prevail solely in the course of a washing, drying or dishwashing cycle. The position of the opening mechanism and/or the compartment(s) after emptying of at least one compartment is changed relative to each other, such that the opening mechanism can then open at least one other compartment, when another activation occurs.
