- the invention relates to a push button for a dispensing system of a product under pressure, as well as such a dispensing system.
- the dispensing system is intended to equip bottles used in perfumery, in cosmetics or for pharmaceutical treatments.
- this type of bottle contains a product which is returned by a dispensing system comprising a device for sampling under pressure of said product, said system being actuated by a push button to allow the product to be sprayed.
- the sampling device comprises a pump or a manually operated valve via the push button.
- Such push buttons are conventionally made in two parts: an actuating body and a spray nozzle of the product which are associated with each other to form a swirl assembly comprising a vortex chamber provided with a dispensing orifice and at least one supply channel of said chamber.
- the supply channels open tangentially in the vortex chamber which is cylindrical of revolution to rotate very rapidly the product, the dispensing orifice having a reduced diameter relative to that of said chamber so that the product in rotation escapes through said orifice with a speed sufficient to split into droplets forming the aerosol.
- the aerosol is composed of droplets of very different sizes.
- the aerosol is commonly consists of droplets of diameter between 5 ⁇ and 300 pm.
- the large droplets are heavier than the smaller ones and follow a different distribution path, which can cause indelible stains in the case of perfumes.
- small droplets are the lightest and can be inhaled, which may be the goal in the case of drugs, but this can be an undesirable effect in the case of toxic products.
- the place of application for example within the respiratory system, depends on the size of the droplets, and the large disparity in size distorts the treatment.
- the size of the droplets from a vortex chamber depends in part on the force and speed with which the user actuates the pump pressing the push button with his finger, because the induced pressure depends on it.
- a push button comprising a distribution chamber which is provided with channels each converging towards an outlet orifice, said convergent channels being arranged to allow the impaction of the jets of product distributed by said orifices.
- the feeding of the convergent ducts or vortex chamber according to the prior art does not allow fractionation of the dose of product to be dispensed, that is to say, to restore only a part of the expected dose by the pump.
- the support stroke of the push button is performed too fast, in particular of the order of 0.2 seconds for 120 ⁇ , to be interrupted by the user.
- the invention aims to solve the problems of the prior art by proposing in particular a push button for the distribution of an aerosol formed droplets having improved calibration and spatial distribution, and this by increasing the production time of said aerosol.

- the push button comprises a body 1 having an annular skirt 2 surrounding a well 3 for mounting the push button on a feed tube 4 of the pressurized product. Furthermore, the push button comprises an upper zone 5 allowing the user to exert a digital support on said push button in order to move it axially. In the embodiment shown, the push button is equipped with a decorative embellisher 6 which surrounds the body 1 and on which is formed the upper support zone 5.

- the housing 10 has an axis perpendicular to that of the mounting well 3 to allow lateral spraying of the product relative to the body 1 of the push button.
- the housing 10 may be collinear with the well 3, in particular for a push button forming a nasal spray tip.
- the housing 10 is provided with an anvil 11 around which a spray nozzle 12 is mounted so as to form a distribution path of the product under pressure between said housing and a vortex assembly.
- the anvil 11 extends from the bottom of the housing 10 leaving a channel 13 for communication between the well 3 and said housing.
- the nozzle 12 has a cylindrical side wall 14 of revolution which is closed forwardly by a proximal wall 15.
- the association of the nozzle 12 in the housing 10 is formed by fitting the outer face of the side wall 14, the rear edge of said outer face being further provided with a radial projection 16 for anchoring the nozzle 12 in said housing.
- an impression of the vortex assembly is formed recess in the proximal wall 15 and the anvil 11 has a flat distal wall 17 on which the proximal wall 15 of the nozzle 12 is supported to delimit between them all vortex.
- an impression of the swirl assembly can be formed directly on a wall of the housing 10, in particular for a spray nozzle.
- the distal wall 17 may have a convexity turned towards the inside of the swirl assembly.
- the nozzle 12 and the body 1 are made by molding, in particular of a different thermoplastic material.
- the material forming the nozzle 12 has a stiffness that is greater than the stiffness of the material forming the body 1.
- the significant stiffness of the nozzle 12 prevents its deformation during its mounting in the housing 10 so to guarantee the geometry of the whirlpool assembly.
- the lower stiffness of the body 1 allows improved sealing between the mounting well 3 and the feed tube 4.
- the body 1 is made of polyolefin and the nozzle 12 is made of cycloolefinic copolymer (COC), poly (oxymethylene) or poly (butylene terephthalate).

- This embodiment therefore makes it possible to combine the advantages of the use of a vortex chamber 22 with that of the impaction of the product, without having the disadvantages thereof, especially with regard to the dispersion of droplet sizes and the risks of non-impaction of the product.
- the impaction of the swirling web allows in particular the realization of an aerosol formed of a uniform spatial distribution of droplets suspended in the air, the size of said droplets being small and uniform.
- the aerosol can then have the appearance of a smoke plume with droplet sizes of between 10 ⁇ and 60 ⁇ with an average of 35 ⁇ for an alcoholic product, and whatever the support force that the user exerts on the push button.
