Abstract
A nozzle head for dispensing sealant within a gap is provided. The nozzle head includes, but is not limited to, a body section and a port connected with the body section. The body section forms a primary channel through which sealant is dispensed. The primary channel forms an entrance through which sealant enters the body section and an exit through which sealant is dispensed from the nozzle. The port is connected with the body section and surrounds the exit. The port forms a chamber having a tip portion opposed to a rear opening. The chamber forms an angled path from the tip portion to the rear opening to trap and guide excess sealant within the chamber to the rear opening.
