ABSTRACT:
A product comprising a container having a closed top, side wall and open mouth bottom; a removable lid closing the container open mouth bottom; an opening in the container top; a tab removably closing the opening in the container top; and a solid detergent composition in the container having a shape conforming to the internal volume defined by the container top and a substantial height of the side wall extending downwardly from the top.
A method of washing dishes and utensils in a dishwashing machine comprising placing soiled dishes and utensils in a dishwashing machine having a washing chamber; removing the container lid and the tab closing the opening in the container top; placing the product in a dishwashing machine with the container top upright and the container and solid detergent block bottoms supported on a foraminous surface with clearance space between the block and container wall; closing the dishwashing machine and supplying washing water to the machine washing chamber as a spray so that water enters the opening in the container top and flows downwardly in the container along the side of the block thereby dissolving some of the detergent and forming a detergent solution which flows out of the container and mixes with water to form a washing solution; and recycling the washing solution into washing contact with the dishes and utensils to clean them.
