Abstract
The invention is a single use container having an outer enclosure and an inner compartment isolated therefrom and is advantageous for the machine washing of laundry using detergent compositions having mutually incompatible constituents. Through an opening, the inner compartment receives a constituent of a detergent composition, such as a peroxidic additive. The outer enclosure receives another constituent of the detergent composition through a separate opening. For storage and for sale, a hood crowns the upper part of the container sealing the openings of the enclosure and compartment, thereby isolating the constituents of the enclosure and compartment. With the hood removed, the container is inserted into the drum of a washing machine. Simultaneous and gradual release of the constituents within the enclosure and compartment occurs during the washing operation.
