Definitions
- 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 liquid 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 as well as at least one a supply channel of said chamber.
- the feed channels can lead tangentially into the vortex chamber which is cylindrical of revolution to rotate the product very quickly, the dispensing orifice having a reduced diameter relative to that of said chamber so that the rotating product escapes through said orifice at high speed and under high pressure.
- the stream of product in rotation then passes through a transient unsteady flow phase, called “pre-spray”, then splits into droplets and forms the aerosol, also called “spray”.
- the aerosol is composed of droplets of very different sizes.
- the aerosol is commonly constituted by droplets of diameter between 5 ⁇ m and 300 ⁇ m.
- 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 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.
- the aerosol tends to be hollow, which is always the case when the product is low viscosity, especially with a viscosity of less than about 10 times that water, and that the desired spray angle is greater than 45 °.
- the envelope of the aerosol of substantially conical shape at least in its first half, consists of the majority of the droplets while there is little inside the cone. This can be seen by spraying the aerosol on a sheet of blotting paper: the wet trace is annular while it should cover a disc. In particular, this distribution of droplets can be harmful for dermal applications.
- the user can not fractionate the dose, that is to say, return only a portion of the nominal dose provided by the pump, limiting its support stroke on the push button.
- the aerosol is produced too short, in particular of the order of 0.2 seconds for 130 microns, to be interrupted by the user.
- the document FR-2 903 328 proposes to use a non-swirling nozzle which is equipped with a micro-grid to ensure the calibration and the spatial distribution of the droplets.
- this embodiment requires cross sections through the micro-grid which are extremely small, in particular of the order of 6 microns in diameter, which imposes a fine filtration of the liquid to avoid clogging problems.
- the difficulty of making and assembling in the body of these micro-grids remains high.
- a push button comprising a distribution chamber which is provided with distribution channels each converging towards an outlet orifice, said convergent channels being arranged to allow impaction of the product jets distributed by said orifices.
- This embodiment allows a better control of the average size of the droplets and a small dispersion of their size.
- the quality of the aerosol is substantially independent of the force or speed of support on the push button.
- the aim of the invention is to solve the problems of the prior art by proposing in particular a push button enabling the distribution of an aerosol formed of droplets having improved calibration and spatial distribution, and this in a particularly reliable manner with respect to the constraints of industrial manufacture. in large series.
- the invention proposes 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 feeding 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 at least two vortex chambers, each of said vortex chambers comprising at least one feed channel for rotating the product in said chamber and a distribution channel for a rotated product stream, said distribution channels each converging from an inlet port to an outlet orifice at an angle which is arranged to allow the impaction of the streams of product distributed by said anal.
- the invention proposes a system for dispensing a product under pressure, comprising a sampling device equipped with a tube for feeding the pressurized product on which the well of such a push button is mounted to allow spraying of the product.
- a push button for a dispensing system for a product in particular liquid under pressure, is described below, said product being 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 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 dispensing system comprises a sampling device 7 equipped with a feed tube 4 of the pressurized product which is sealed in the well 3.
- the dispensing system further comprises mounting means 8 on a bottle 9 containing the product and means 10 for taking the product inside said bottle which are arranged to supply the feed tube 4 with pressurized product.
- the sampling device 7 may comprise a manually operated pump or, in the case where the product is packaged under pressure in the bottle 9, a manually operated valve.
- the pump or the valve is actuated to supply the supply tube 4 with pressure product.
- the body 1 also has an annular housing 11 which is in communication with the well 3.
- the housing 11 is of 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 11 may be collinear with the well 3, in particular for a push button forming nasal spraying nozzle.
- the housing 11 is provided with an anvil 12 around which a spray nozzle 13 is mounted so as to form a distribution path of the product under pressure between said housing and a vortex assembly.
- the anvil 12 extends from the bottom of the housing 11 leaving a channel 14 for communication between the well 3 and said housing.
- the nozzle 13 has a cylindrical side wall 15 of revolution which is closed forwardly by a proximal wall 16.
- the association of the nozzle 13 in the housing 11 is formed by fitting the outer face of the side wall 15, the rear edge of said outer face being further provided with a radial projection 17 for anchoring the nozzle 13 in said housing.
- an impression of the vortex assembly is formed recess in the proximal wall 16 and the anvil 12 has a distal wall 18 forming a flat surface on which the proximal wall 16 of the nozzle 13 is supported to delimit the swirling assembly between said walls.
- an impression of the swirl assembly can be formed directly on a wall of the housing 11, in particular for a spray nozzle.
- the nozzle 13 and the body 1 are made by molding, in particular of a different thermoplastic material.
- the material forming the nozzle 13 has a stiffness that is greater than the stiffness of the material forming the body 1.
- the significant stiffness of the nozzle 13 prevents its deformation during its mounting in the housing 11 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 13 is made of cycloolefinic copolymer (COC), poly (oxymethylene) or poly (butylene terephthalate).
- the inner face of the side wall 15 of the nozzle 13 and the outer face of the anvil 12 have a cylindrical geometry of revolution which are arranged opposite to form the distribution path between them.
- the distribution path has axial ducts 19 which are each formed between two spacers 20 which extend on the internal face of the side wall 15 of the nozzle 13.
- the spacers 20 have a free wall which is arranged facing the outer face of the anvil 12 with a reduced clearance in order to ensure the centering of the nozzle 13 on the anvil 12 and thus to make reliable the tight closure of the swirling assembly between the walls 18, 16.
- the vortex assembly comprises at least two vortex chambers 21 each comprising at least one feed channel 22 to ensure the rotation of the product in said chamber and a distribution channel 23 of a stream of product rotated.
- the vortex chambers 21 have a cylindrical geometry of revolution which is fed tangentially by at least one feed channel 22, the distribution channel 23 being formed on the distal end of said geometry.
- the vortex chambers 21 comprise a single supply channel 22 which is in communication with an axial duct 19, said supply ducts extending radially to feed tangentially the vortex chambers 21. realization reduces the pressure losses induced.
- each distribution channel 23 has an inlet orifice which is off-center opposite the supply channel 22 to allow the ejection of the product rotated in the vortex chamber 21.
- the distribution channels 23 each converge from the inlet port to an outlet port at an angle which is arranged to allow the impingement of product streams dispensed by said channels.
- the distribution channels 23 can be made by laser drilling, or else by injection under pressure of rigid thermoplastic material such as polyacetal, the nozzle 13 can then be made in two parts, the proximal wall 16 and the side wall 15, so to simplify the injection mold.
- the vortex assembly comprises two chambers 21 for the impaction of two streams, but more than two vortex chambers 21 could be used, including three or four vortex chambers 21.
- the impaction of the rotated product streams is carried out during their unsteady flow transient phase to promote the formation of the aerosol A by impaction.
- the distance d between the outlet ports and the impingement point P of the product streams may be small, for example between 1 and 5 mm, to ensure the impaction of the pre-sprays.
- the nozzle 13 has a front housing 24 in which the outlet openings open, the angle of convergence of the distribution channels 23 being arranged to allow the impaction of the product streams inside said housing. .
- the formation of aerosol A is ensured by impaction and / or by fractionation in air, both with water and with products with higher surface tension, for example with perfumes.
- the aerosols are homogeneous, consisting of droplets of very similar dimensions, and are particularly suitable, for example, inhalable drugs, indoor perfumes, or makeup-fixing products.
