Definitions

the invention relates to a push button for a system for dispensing a product under pressure, as well as such a distribution system.
the distribution system is intended to equip bottles used in perfumery, cosmetics or for pharmaceutical treatments.
this type of bottle contains a product which is returned by a distribution system comprising a device for taking pressure of said product, said system being actuated by a push button to allow spraying of the product.
the sampling device comprises a pump or a valve with manual actuation by means of the push button.
Such push buttons are conventionally produced in two parts: an actuating body and a product spray nozzle which are associated with each other to form a vortex assembly comprising a vortex chamber provided with a dispensing orifice and at least one supply channel for said chamber.
the feed channels open tangentially into the vortex chamber which is cylindrical in revolution to rotate the product very quickly, the dispensing orifice having a reduced diameter compared to that of said chamber so that the product in rotation s 'escapes through said orifice with sufficient speed to break up into droplets forming the aerosol.
the aerosol is made up of droplets of very varied sizes.
the aerosol is commonly found to be droplets of diameter between 5 ⁇ m and 300 ⁇ m.
the large droplets are heavier than the smallest and follow a different distribution path, which can cause permanent stains in the case of perfumes.
the small droplets are the lightest and can be inhaled, which can be the objective sought in the case of drugs, but which can be an adverse effect in the case of toxic products.
the place of application for example inside the respiratory system, depends on the size of the droplets, and the great disparity in sizes distorts the treatment.
the size of the droplets from a vortex chamber partly depends on the force and the speed with which the user actuates the pump by pressing the push button with his finger, because the induced pressure depends on it.
the aerosol tends to be hollow with a substantially conical envelope which consists of the majority of the droplets while there are few of them. inside the cone.
this distribution of droplets can be harmful for dermal applications.
a push button comprising a dispensing chamber which is provided with channels each converging towards an outlet orifice, said convergent channels being arranged to allow the jets of product dispensed by said orifices to be impacted.
Such push buttons are also known from documents EP 0 412 524 A1 and FR 2 927 551 A1 .
the supply of the converging conduits or of the vortex chamber according to the prior art does not allow a fractionation of the dose of product to be dispensed, that is to say of restoring only part of the planned dose by the pump.
the push button press stroke is carried out too quickly, in particular of the order of 0.2 seconds for 120 ⁇ l, to be able to be interrupted by the user.
the invention aims to solve the problems of the prior art by proposing in particular a push button allowing the distribution of an aerosol formed of droplets having an improved calibration and spatial distribution, and this by increasing the duration of production of said aerosol.
the invention provides a push button for a system for dispensing a product under pressure, said push button comprising a body having a mounting well on a tube for supplying the product under pressure. and a housing in communication with said well, said housing being provided with an anvil around which a spray nozzle is mounted so as to form a product distribution path between said housing and a vortex assembly comprising a vortex chamber provided with a dispensing orifice as well as at least one supply channel for said chamber, said vortex chamber being delimited by a lateral surface having a frustoconical geometry with respect to which the supply channel or channels extend in a transverse plane, said lateral surface being convergent from an upstream end into which tangentially opens the downstream end of the or supply channels to a downstream feed opening of the dispensing orifice, said dispensing orifice having an outlet dimension which is equal to the internal dimension of said downstream opening.
the invention provides a system for distributing a product under pressure, comprising a sampling device equipped with a tube for supplying the product under pressure on which the well of such a push button is mounted for allow the product to be sprayed.
a push button is described below for a system for dispensing a product, in particular a liquid under pressure, said product being able to be of any kind, in particular used in perfumery, in cosmetics or for pharmaceutical treatments.
the push button comprises a body 1 having an annular skirt 2 which surrounds a well 3 for mounting the push button on a supply tube 4 for the product under pressure. Furthermore, the push button includes an upper zone 5 allowing the user to exert a digital press on said push button in order to be able to move it axially. In the embodiment shown, the push button is equipped with an embellishment 6 of appearance which surrounds the body 1 and on which the upper support zone 5 is formed.
the distribution system comprises a withdrawal device 6 equipped with a tube 4 for supplying the pressurized product which is inserted in leaktight manner in the well 3.
the distribution system also comprises mounting means 7 on a bottle 8 containing the product and means 9 for taking the product inside said bottle which are arranged to supply the supply tube 4 with product under pressure.
the sampling device 6 can comprise a manually actuated pump or, in the case where the product is conditioned under pressure in the bottle 8, a manually actuated valve.
a manually actuated pump or, in the case where the product is conditioned under pressure in the bottle 8, a manually actuated valve.
the body 1 also has an annular housing 10 which is in communication with the well 3.
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 can 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 for the product under pressure between said housing and a vortex assembly.
the anvil 11 extends from the bottom of the housing 10, leaving a communication channel 13 between the well 3 and said housing.
the nozzle 12 has a cylindrical side wall 14 of revolution which is closed towards the front by a proximal wall 15.
the association of the nozzle 12 in the housing 10 is achieved by fitting the external face from the side wall 14, the rear edge of said external face being further provided with a radial projection 16 for anchoring the nozzle 12 in said housing.
an imprint of the vortex assembly is formed in the hollow 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 in abutment to delimit the assembly between them. swirling.
an impression of the vortex assembly can be formed directly on a wall of the housing 10, in particular for a nasal spray nozzle.
the distal wall 17 may have a convexity facing the interior of the vortex assembly.
the nozzle 12 and the body 1 are produced by molding, in particular from a different thermoplastic material.
the material forming the nozzle 12 has a rigidity which is greater than the rigidity of the material forming the body 1.
the significant stiffness of the nozzle 12 makes it possible to avoid its deformation during its mounting in the housing 10 so to guarantee the geometry of the vortex assembly.
the lower stiffness of the body 1 allows improved sealing between the mounting well 3 and the supply tube 4.
the body 1 is made of polyolefin and the nozzle 12 is made of cyclo olefin copolymer (COC), poly (oxymethylene) or poly (butylene terephthalate).
the distribution path supplies pressurized product with the vortex assembly which comprises a vortex chamber 22 provided with a distribution orifice 23 as well as at least one channel 24 for supplying said chamber.
the supply channels 24 communicate with the downstream annular conduit 21.
this embodiment makes it possible to limit the length of the supply channels 24 in order to reduce the induced pressure losses.
the vortex chamber 22 is delimited by a lateral surface 25 having a frustoconical geometry which extends along a distribution axis D, the distribution channels 24 extending in a plane transverse to said distribution axis.
the terms of positioning in space are defined relative to the distribution axis.
the frustoconical geometry is of revolution around the distribution axis D, an internal dimension of said geometry then corresponding to a diameter.
the frustoconical geometry can be of polygonal section, an internal dimension of said geometry then corresponding to a diameter of the envelope inscribed in said geometry.
the lateral surface 25 converges from an upstream end 26 into which the downstream end of the supply channels 24 tangentially opens to a downstream opening 27 supplying the distribution orifice 23.
the distribution orifice 23 has an outlet dimension which is equal to the internal dimension of the downstream opening 27.
the angle of convergence of the lateral surface 25 can be between 30 ° and 50 °, in particular of the order of 45 °.
the upstream end 26 has a cylindrical geometry of revolution in which the downstream end of the supply channels 24 opens tangentially.
the tangential supply of the swirl chamber 22 makes it possible to put the product in rotation in the upstream end 26 of said chamber, the product is then pressed and pushed in rotation along the lateral surface 25 of said chamber forming a sheet of product whose speed of rotation increases and which converges towards the downstream opening 27, then said convergent sheet can escape through the dispensing orifice 23 without being deformed so as to be able to impact to form the aerosol.
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, in particular relative to the dispersion of droplet sizes and to the risks of non-impaction of the product.
the impact of the swirling sheet allows in particular the production 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 plume of smoke with droplet sizes between 10 ⁇ m and 60 ⁇ m with an average of 35 ⁇ m for an alcoholic product, whatever the support force that the user exercises on the push button.
the vortex assembly has two channels 24 for supplying the vortex chamber 22, said channels being arranged symmetrically with respect to the distribution axis D.
each channel 24 has a U-shaped section which is delimited between an outer wall 28 and an inner wall 29.
the outer wall 28 is tangent to the upstream end 26 and the inner wall 29 is offset from it by a distance less than 30% of the internal dimension of the upstream end 26 so as to avoid impaction of the product in said upstream end.
the inner wall 29 is parallel to the outer wall 28.
the inner wall 29 has an angle of convergence with the outer wall 28 in the upstream-downstream direction, the offset between said said walls then being measured at the unblocking section of the channels 24 in the upstream end 26.
more than two supply channels 24 can be provided, in particular three channels 24 arranged symmetrically with respect to the distribution axis D, or a single channel 24 can be provided for tangentially supplying the vortex chamber 22.
downstream end of the feed channel 24 or all of the downstream ends of each of the feed channels 24 form a feed section of the vortex chamber 22.
this feed section it is possible to provide for this feed section to be small relative to the interior surface of the upstream end 26.
the area of the feed section may be less than 10% of the interior surface of the upstream end 26.
the surface of the feed section can be between 0.01 mm 2 and 0.03 mm 2 .
the internal dimension of the upstream end 26 is 0.6 mm, i.e. a internal surface of 0.28 mm 2
each channel 24 has a width and a depth of 0.1 mm, that is an area of 0.02 mm 2 for the supply section.
the channels 24 may have a width of 70 ⁇ m and a depth of 130 ⁇ m.
the dispensing time is increased.
the duration of dispensing can be between 0.5 and 2 seconds so as to leave the possibility for the user to interrupt the dispensing of the aerosol during actuation.
downstream opening 27 of the swirl chamber is surmounted by a distribution orifice 23 having a cylindrical geometry of revolution around the distribution axis D, the internal dimension of said orifice being equal to the internal dimension downstream opening 27.
the axial dimension of the dispensing orifice 23 is small compared to its internal dimension, so as not to disturb the convergence of the swirling sheet.
the axial dimension of the dispensing orifice 23 can be less than 50% of its internal dimension.
downstream opening 27 of the swirl chamber 22 can form a dispensing orifice 23.
the aerosol is particularly satisfactory when the internal dimension of the downstream opening 27 is small relative to the internal dimension of the upstream end 26, so that the impact of the sheet is carried out as close as possible to the distribution orifice 23.
the internal dimension of the downstream opening 27 can be less than 50% of the internal dimension of the upstream end 26, more precisely by being between 20% and 40% of said internal dimension.
the axial dimension of the vortex chamber 22 is relatively large, in particular of the order or greater than the internal dimension of the upstream end 26, so as to allow the establishment of the swirling sheet along the lateral surface 25 of said vortex chamber and to impart progressive convergence.
the axial dimension of the vortex chamber 22 is at least equal to 80% of the internal dimension of the upstream end 26, more precisely being between 90% and 200% of said internal dimension.
the internal dimension of the upstream end 26 is 0.6 mm
the internal dimension of the downstream end 27 is less than or equal to 0.24 mm, being in particular between 0.15 mm and 0.24 mm
the axial dimension of the vortex chamber 22 is at least equal to 0.55 mm
the axial dimension of the dispensing orifice 23 is less at 0.10 mm.
