The Foodmax Corporation manufactures a line of salad dressings. All are packaged in bottles with ordinary screw tops. Marketing studies conducted by Foodmax indicate, however, that many of Foodmax's customers would prefer bottles with shaker tops, which make it easier to dispense salad dressing in just the quantities wanted.
