Abstract:
A detergent mould for casting shaped, detergent articles, wherein said mould comprises at least two rigid complimentary dies each of which has a surface which, upon engagement of the dies, define a cavity corresponding to a desired shape of the cast detergent article,wherein said engaged dies further form a reservoir which on one side is open to receive cast melt and, on another side, is open to the cavity; wherein the volume ratio of the reservoir to the cavity is 5% to about 50%; wherein the reservoir forms a unit that is removable from the rest of the mould to permit removal of cast melt remaining in the reservoir away from the cast article; and wherein the shaped article which is cast in said mould is a solid article; and wherein the thickness and width of the dies in a region of engagement of at least said two dies is adapted to allow relatively faster cooling of said engagement region than elsewhere.
