Device for packaging and dispensing a product, with vial and dispensing mouthpiece equipped with a filter

A device for packaging and dispensing a product, generally a liquid or gel product, comprising:

• a container delimiting an internal volume and intended to contain the product,
• a dispensing head, provided with a dispensing end and an actuating part, to dispense a portion or dose of the product;
• a mounting interface belonging to the dispensing head and adapted to be fixed onto the container by a fixing portion;
• an assembly for refilling and filtering air, said assembly comprising an outer air intake orifice and a check valve allowing air entering through the outer orifice to penetrate the internal volume after a product dispensing;
• wherein the outer orifice is formed at a distance from a bottom of the container, the assembly for refilling and filtering air comprising a filter element which is:
• mounted in the dispensing head;
• placed in an air circulation duct which extends between the outer orifice and the check valve;
• and
• at a distance and offset inwardly from both of the container and said fixing portion,
• wherein the outer orifice forms a lateral outlet of the air circulation duct through an outer wall of the dispensing head, so that an entry section of the air circulation duct extends radially toward the filter element.

• wherein the air circulation duct comprises an entry section which extends axially between:
• the outer orifice;
• and a duct widening area located upstream of the filter element in the inflow direction of the circulation of air, and
• wherein the outer orifice forms an axial inlet of the air circulation duct through the dispensing end, the duct being formed by a rigid tubular element formed in one piece.
