  • Patent number: 9902926
    Abstract: This invention concerns dosage elements for a ware washing machine and a method of manufacturing such dosage elements. In embodiments of the invention a dosage element comprises first (10) and second (20) joined parts, wherein the first part (10) is a part which, prior to joining with the second part (20), comprised an open receptacle and wherein the second part (20) comprises a substrate carrying a plurality of mutually separated substances A, B, C arranged in side by side relation. The second part (20) is joined to said first part (10) so as to close said receptacle and enclose said substances within it. Dosage elements produced in the inventive method are pleasant to handle, while being surprisingly resistant to damage in handling or transit.
