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.

Abstract: A dispensing pump coupled with a container has a pump body having an end coupled with a button cap. The button cap has a spray nozzle and a pump chamber that contains fluid to be dispensed through the spray nozzle. Inside the pump body is a plunger, a stationary tube with fingers, a biasing member, and a duckbill valve with a slit. When the plunger is in an extended position, the fingers act against the plunger to close the slit of the duckbill valve. As the button cap is depressed, the plunger translates to a depressed position thereby allowing the fingers to spread apart from the duckbill valve and open up the slit such that fluid from the container can fill up the pump chamber. The biasing member urges the plunger back to the extended position, thereby urging the opposed fingers to return to the closed position.
