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. ## Claims ### Claim 1 A device for packaging and dispensing a flowable product, comprising: a casing comprising a nozzle for dispensing the product and a container designed to contain the product to be packaged, the casing comprising a rigid bottom; an air renewal and filtration assembly for air entering the container after a dose of product had been dispensed; a filter element for filtering air entering the container; an air inlet passage located in said rigid bottom, the rigid bottom comprising an interior surface facing the inside of the container and covered by said filter element; wherein said nozzle extends around a central axis and 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, said actuating portion being axially shifted with respect to the free end; an outer contact surface defined by the actuating portion, and when pressure is applied to the actuating portion at the outer contact surface by a user, the actuating portion is capable of expelling product; a displaceable inner surface that follows movement of the actuating portion; a first valve to allow the product to pass out through the free end when pressure is applied to said actuating portion without allowing external air to enter said casing through the free end when said actuating portion is released; wherein said device further comprises: a second valve arranged in such a way as to isolate a dose-defining chamber from the air contained in the container, the dose-defining chamber having a determined volume in the rest position of the actuating portion; a rigid stopper element provided with an abutment surface that defines with said displaceable inner surface the dose-defining chamber, said engagement position being obtained by engaging the actuating portion of the nozzle against the abutment surface of the rigid stopper element; and wherein the displaceable inner surface is in contact with and entirely covers the abutment surface in said engagement position of the actuating portion, so that the dose of product dispensed when moving the actuating portion from the rest position to the engagement position corresponds to the determined volume of the dose-defining chamber. ### Claim 2 (depends on 1) The device as claimed in claim 1, wherein the nozzle comprise a stationary portion, the actuating portion being connected to the stationary portion by a resilient connecting portion, at least one of the actuating portion and the stationary portion having a greater thickness than the resilient connecting portion. ### Claim 3 (depends on 1) The device as claimed in claim 1, wherein the actuating portion is adjacent to at least one flexible hinge that is part of the nozzle, so that the actuating portion is actuated as a push button to obtain the engagement position. ### Claim 4 (depends on 3) The device as claimed in claim 3, comprising guiding means configured to guide movement of the actuating portion toward the rigid stopper element and prevent deviation with respect to a predetermined pushing direction for pushing the actuating portion. ### Claim 5 (depends on 3) The device as claimed in claim 3, wherein the flexible hinge extends at the opposite of the free end of the nozzle and the actuating portion is configured to be pushed according to a direction parallel to the central axis. ### Claim 6 (depends on 3) The device as claimed in claim 3, wherein the actuating portion is configured to be pushed according to a direction perpendicular to the central axis. ### Claim 7 (depends on 6) The device as claimed in claim 6, wherein the dose-defining chamber extends between two side faces that are hermetically connected, radially, to the rigid stopper element, said two side faces defining an angle inferior or equal to 120° at the connection to the rigid stopper element. ### Claim 8 (depends on 1) The device as claimed in claim 1, wherein the actuating portion extends between the first valve and the second valve, said second valve being arranged in the internal volume of the casing and fixed to a rigid element that is spaced from said rigid bottom. ### Claim 9 (depends on 1) The device as claimed in claim 1, further comprising a third valve designed to prevent the escape of product and air when the device is not being used, said third valve being arranged between said filter element and the internal volume of the container to prevent any contact between the product and said filter element. ### Claim 10 (depends on 2) The device as claimed in claim 2, wherein the actuating portion and the resilient connecting portion are parts of a flexible portion of the nozzle distinct from the stationary portion that is rigid, and wherein the actuating portion comprises: a first layer made of a first material and integral with the flexible portion of the nozzle; and a second layer made of a second material more rigid than the first material. ### Claim 11 (depends on 10) The device as claimed in claim 10, wherein said second layer is connected to the stationary portion by an auxiliary hinge and is configured to pull the first layer outwards when the actuating portion is released. ### Claim 12 (depends on 10) The device as claimed in claim 10, wherein said second layer defines the outer contact surface of the actuating portion. ### Claim 13 (depends on 2) The device as claimed in claim 2, wherein said container comprises a substantially rigid portion to which the stationary portion of the nozzle is directly fixed, the stationary portion comprising a rigid portion. ### Claim 14 (depends on 1) The device as claimed in claim 1, wherein said first valve is formed by at least a portion of the nozzle itself. ### Claim 15 (depends on 1) The device as claimed in claim 1, wherein the rigid bottom defines a base at the opposite end of the casing from the nozzle, the rigid bottom allowing the casing to be maintained according to a vertical position. ### Claim 16 (depends on 15) The device as claimed in claim 15, wherein the rigid bottom comprises: a central portion surrounded by a continuous annular portion; and a central recess obtained by a reduction of thickness of the central portion as compared to the thickness of the annular portion. ### Claim 17 (depends on 16) The device as claimed in claim 16, wherein the filter element extends in the central recess. ### Claim 18 (depends on 16) The device as claimed in claim 16, wherein the air inlet passage is located in the central portion of said rigid bottom. ### Claim 19 (depends on 1) The device as claimed in claim 1, further comprising a protective cap, and wherein said nozzle comprises an external thread so that said protective cap can be screwed directly on said nozzle, the protective cap covering the outer contact surface of the actuating portion. ### Claim 20 (depends on 1) The device as claimed in claim 1, wherein said actuation portion is defined in a side wall of the nozzle and is arranged to be pushed radially toward the central axis, said nozzle being arranged around a central axial seat, the first valve allowing the product to be dispensed through a non-annular channel defined along said central axial seat.
