Abstract
A device for packaging and dispensing a flowable product comprises a casing comprising a nozzle for dispensing the product and a container designed to contain the product to be packaged. The casing comprises a rigid bottom, an air renewal and filtration assembly, a filter element, and an air inlet passage located in said rigid bottom. The nozzle comprises a tapered portion that defines a free end of the nozzle, an actuating portion resiliently movable between an engagement position and a rest position. A dose-defining chamber may be isolated from the air contained in the container and may have a determined volume in the rest position. The engagement position may be obtained by engaging the actuating portion against a stationary wall portion, so as to empty the chamber and expel a dose exactly corresponding to the determined volume of the chamber.
