US Patent No. 8,338,357 B2; Reckitt Benckiser has been awarded a patent covering a multiple dosing ware washing article that is comprised of a rack of solid dosage elements of a cleaning composition in an article that is comprised of sleeves that retains the dosage elements.
The sleeves, which are formed by a molded or thermoformed tray, have two openings at opposite ends so that water may enter one end and leave the other end carrying with it dissolved or broken away cleaning composition. There is also a gap between dosage elements in a non-nested position sufficient to allow the article to be formed into a nested position without hindrance between the dosage elements. The article is adapted to be retained as a refill within a holder, located in use in a dishwashing machine.
