Abstract

The dispenser is for dispensing viscous products, has an ergonomic shape, and an automatic closure. The closure opens promptly upon initiation of an actuator and before the flow of viscous product from the dispenser. Further, the closure closes the dispenser outlet at the end of the return of the actuator to its rest position. Further, an outlet valve from a pump chamber remains open as an inlet valve to the pump chamber opens. This causes a suckback of viscous product near the dispenser outlet to flow into the dispenser. The automatic closure does not close as dispenser outlet until the suckback of viscous product has occurred. The automatic closure also functions as a knife or blade to assist in cutting the viscous product to maintain cleanliness and hygiene of the package.
