The invention is a device for packaging and applying a product. The device includes a receptacle for containing the product and an applicator including a rod provided at one end with an application element. The receptacle further has a tubular body with a movable piston guided axially in the tubular body wherein the piston has a passage opening for the application element. The applicator includes an axial stop protruding radially relative to the rod and is capable of being in abutment against the piston. The stop can be retracted radially in order to allow it to pass through the passage opening of the piston and includes at least one orifice for the passage of air when the stop is in abutment against the piston.

1. Packaging and application device for a product, comprising: a receptacle for containing the product to be applied;an applicator comprising a rod which is provided at one end with an application element which can be introduced into the receptacle in order to remove the product, the receptacle comprising: a tubular body;a movable piston which is guided axially in the tubular body, which piston defines a passage opening for the application element and the rod, the applicator comprising, along the length of the rod, at least one axial stop which protrudes radially relative to the rod and which is capable of being in abutment against the piston along the periphery of the passage opening, wherein the stop can be retracted radially in order to allow it to pass through the passage opening of the piston and defines at least one orifice for the passage of air when the stop is in abutment against the piston. 2. Packaging and application device according to claim 1, wherein the stop comprises, along the length of the rod, a radial widening which locally increases the cross-section of the rod, and wherein the at least one air passage orifice comprises at least one recess which is provided in the radial widening. 3. Packaging and application device according to claim 2, wherein the radial widening has a plurality of separate lugs which are distributed at the periphery of the rod and which extend away from the shaft of the rod as far as radial tips in the direction of the application element, the lugs being separated by recesses which extend partially along the length of the rod. 4. Packaging and application device according to claim 3, wherein the lugs have at the outer side a surface which diverges radially relative to the shaft of the rod in the direction of the application element. 5. Packaging and application device according to claim 4, wherein the inclination of the lugs relative to the shaft of the rod is between 1 and 10 degrees. 6. Packaging and application device according to claim 5, wherein the rod comprises a tubular casing and the lugs are integral with the tubular casing in the continuation thereof. 7. Packaging and application device according to claim 5, wherein the radial tips constitute the free ends of the lugs. 8. Packaging and application device according to claim 4, wherein the rod comprises a tubular casing and the lugs are integral with the tubular casing in the continuation thereof. 9. Packaging and application device according to claim 8, wherein the radial tips constitute the free ends of the lugs. 10. Packaging and application device according to claim 4, wherein the radial tips constitute the free ends of the lugs. 11. Packaging and application device according to claim 3, wherein the inclination of the lugs relative to the shaft of the rod is between 1 and 10 degrees. 12. Packaging and application device according to claim 11, wherein the rod comprises a tubular casing and the lugs are integral with the tubular casing in the continuation thereof. 13. Packaging and application device according to claim 11, wherein the radial tips constitute the free ends of the lugs. 14. Packaging and application device according to claim 3, wherein the rod comprises a tubular casing and the lugs are integral with the tubular casing in the continuation thereof. 15. Packaging and application device according to claim 14, wherein the radial tips constitute the free ends of the lugs. 16. Packaging and application device according to claim 3, wherein the radial tips constitute the free ends of the lugs. 17. Packaging and application device according to claim 1, wherein the stop is radially resiliently deformable. 18. Packaging and application device according to claim 1, wherein the retractable stop has a resistance to passage through the opening of the piston which is greater when the applicator is introduced into the receptacle than the passage resistance of the retractable stop though the opening of the piston, when the applicator is removed from the receptacle. 19. Packaging and application device according to claim 1, wherein the piston comprises, upstream of the passage opening, when viewed in the direction in which the applicator is introduced into the receptacle, a guiding portion having a cross-section which decreases progressively as far as the passage opening, which portion forms a cam surface which is capable of providing radial retraction of the axial stop by means of co-operation with the stop when the applicator is introduced into the receptacle. 20. Packaging and application device according to claim 1, wherein the passage opening comprises, along the periphery thereof, corrugations which are capable of pressing on the rod. 21. Packaging and application device according to claim 1, wherein that the air passage orifice is able to allow the circulation of air to balance the pressures at one side and the other of piston when the retractable stop passes the piston.
