No matter how effective an airless container is, there is usually a degree of air contact inside the actuator, and the answer to this problem is shutoff nozzle. This innovative solution prevents air reentry and bulk exit through the actuator of an airless container. This ensures optimal formulation protection and prevents oxidation of the bulk trapped in the nozzle.
By not letting the product dry out at this end, it also avoids clogging, particularly when the pack is left on the shelf for any length of time. Functionality is deceptively simple. The pressure of the finger on the actuator opens the orifice and pushes the bulk outward. As soon as pressure on the actuator is released, the orifice immediately closes, isolating the product inside the nozzle from the outside.
