Abstract
A tip seal dispenser valve for a pressurized container of a viscous product comprises a valve body, mountable with the container, which includes a hollow valve conduit that defines an outlet orifice and is in fluid communication with the interior of the container. The valve body also includes a hollow actuator channel laterally displaced from the valve conduit. A valve core, formed with a sealing tip, is mounted for axial reciprocal movement in the conduit between a closed position with the tip blocking the outlet orifice and an open position with the tip withdrawn inwardly from the orifice. A fin arrangement guides the core for proper movement in the conduit so that the tip correctly seats in the outlet orifice when closed. The valve core is operated by an actuator button, mounted for axial reciprocal movement in the actuator channel, that is linked to the core so that movement of one causes movement of the other. Further, a seal is associated with the actuator button and channel to prevent leakage thereby.
