Abstract
A valve for a pressurized dispensing container has one or two dispensing openings through the wall of the valve stem. A dispensing nozzle with an actuating handle has a predetermined alignment with the opening or openings in the valve stem so that actuation of the nozzle will assure that one and only one full opening is presented to the product during dispensing. This keeps the leg or wall area between openings out of the path of the product being dispensed and avoids the build up of fiber that tends to clog the opening. A small retaining wall between the valve seat.at the bottom of the valve stem and the lower edge of the opening or openings provides a wall that prevents the flexible rubber-like seal from being distorted under pressure and setting in a position where it blocks the opening when product is to be dispensed. Each of the dispensing openings in the two opening embodiment extends at least 90° around the valve stem and the single opening embodiment may extend as much as 180°.
