The VersaFlow jar eliminates the potential of mess caused by jars with rounded openings that lead to spills or food waste and firm said it could be commercially available in four to five months. The jar, four years' worth of development, can be adapted to a variety of shapes and sizes for the food and beverage industry. It was rolled out for testing at the end of last month by packaging a marinara sauce in a partnership with a local grocer, with customers being asked for their feedback.
