Abstract: A measuring dispenser for particulate material adapted to be placed in a carton of soap or the like comprising a right-triangular receptacle with a divider panel extending from the top panel of the carton along the fold line along which one end of the top panel is pivoted between open and closed position. A closure panel extends down from the top flap to cover a fill opening in the divider panel when the top flap is opened, but pivots away from the divider panel to allow the measuring receptacle to be filled when the box is tilted with the top closure closed.
