特許 係属中 A device capable of controlling the dispensing of the detergent composition, upon contact with the fabric, throughout the maximum duration possible of the cleaning process. The device comprises: - an inner reservoir comprising at least an opening - an outer reservoir The surface of the outer reservoir comprises a plurality of ball retainers wherein a freely rotating ball is seated. The use of freely rotating balls to control detergent dispensing improves cleaning efficiency. This is due to the contact between the washing items and the balls, resulting in a more homogenized liquor throughout the washing machine. This leads to better stain removal and a more efficient washing process. Additionally, this method is cost and time effective as it reduces the amount of detergent, water, and time needed.
