System for dispensing a fluid product
A system for dispensing a fluid product, including a device for taking the product off under pressure that is equipped with an outlet tube, the system also including a push button actuating the device in which a chamber is formed for dispensing the product that is in communication with a well for mounting the push button, the well being arranged to be associated sealingly around an area for mounting the outlet tube so as to allow supply to the chamber dispensing product under pressure emerging from the tube, the outlet tube including a vent recess having at least one opening that is formed in the mounting area and that emerges inside the tube, the opening being located on the mounting area so as to be covered sealingly by the mounting well and to open the inside of the outlet tube to open air when it is not covered.
1. System for dispensing a fluid product, comprising a device for taking off said product under pressure that is equipped with an outlet tube, said system also comprising a push button actuating said device in which a chamber is formed for dispensing the product that is in communication with a well for mounting said push button, said well being arranged so as to be associated sealingly around an area for mounting the outlet tube so as allow supply to the chamber dispensing product under pressure emerging from said tube, said system being characterized in that the outlet tube comprises a vent recess having at least one opening that is formed in the mounting area and emerges inside said tube, said opening being located on the mounting area so as to be covered sealingly by the mounting well and to open the inside of the outlet tube to open air when it is not covered.
2. The dispensing system according to claim 1 , wherein the vent recess has at least one groove that extends radially from the mounting area, said groove being formed on the top end of the outlet tube.
3. The dispensing system according to claim 2 , wherein the radial groove emerges in an annular groove that is in peripheral communication with the inside of the outlet tube.
4. The dispensing system according to claim 2 , wherein a radial groove is extended by an axial groove that is formed on the mounting area.
5. The dispensing system according to claim 4 , wherein the mounting area has an annular throat, the axial groove emerging in said throat.
6. The dispensing system according to claim 1 , wherein the mounting area has a top part with a frustoconical geometry.
7. The dispensing system according to claim 1 , wherein the vent recess has at least one radial channel that passes through a wall of the outlet tube.
8. The dispensing system according to claim 1 , wherein the outlet tube has a central tube around which there is mounted an insert on which the mounting area is formed, said central tube having at least one groove that is in communication with the opening in order to put said opening in communication with the inside of said central tube.
9. The dispensing system according to claim 1 , wherein the outlet tube has an external shoulder above which the mounting area extends.
10. A bottle for dispensing a fluid product, comprising a reservoir for packaging said product and the dispensing system according to claim 1 that is mounted on the reservoir as to enable said product to be dispensed by actuation of the push button.
