Definitions
- the invention relates to a push button for a liquid distribution system, 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 which is returned by a dispensing system comprising a pump or a manually operated valve by means of a push button to allow the spraying of the liquid.
- Such push buttons are conventionally made in two parts: an actuating body and a liquid spray nozzle which are associated with each other to form the push button.
- the spray nozzle may be arranged to form an aerosol with the liquid, in particular by defining a so-called vortex chamber.
- the vortex chamber is arranged to rotate very quickly the liquid to give it speed.
- the swirl chamber is extended at its center by a dispensing orifice, the liquid can escape at high speed by splitting into fine droplets forming the aerosol.
- 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.
- the small droplets are the lightest and can be inhaled, which can be the goal sought in the case of drugs, but this can be an adverse 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 with a substantially conical envelope which consists of the majority of the droplets while there is little to inside the cone.
- this distribution of droplets can be harmful for dermal applications.
- 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 sections of passages 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 dispensing chamber which is provided with channels each convergent towards a dispensing orifice, said convergent channels being arranged to allow impaction of the liquid jets distributed by said orifices.
- the invention proposes a push button allowing in particular to reliably obtain identical and converging jets, and this by using a particularly simple design to achieve by allowing the use of tools and assembly machines traditional push buttons.
- the invention proposes a push button for a liquid distribution system, said push button comprising a body in which a distribution path is formed, an insert being associated in said body of so as to form a distribution chamber between said insert and said body, said chamber comprising channels each converging towards a dispensing orifice, said convergent channels being arranged to allow the impaction of the liquid jets distributed by said orifices, the insert and the body each comprising a cavity having a frustoconical geometry, said geometries, respectively male and female, being arranged so as to be nested one inside the other, forming the convergent channels between them.
- the invention proposes a liquid distribution system comprising a pump or a valve on which such a push button is mounted, the distribution path being in communication with said pump or said valve so as to allow the spraying the liquid by impinging the jets from the convergent channels.
- a push-button for a liquid dispensing system is described below, said liquid 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 in which a distribution path is formed.
- the body 1 has an annular skirt 2 that surrounds a housing 3 mounting the push button on the dispensing system.
- the push button comprises an upper zone 4 allowing the user to exert a digital support on said push button in order to move it axially.
- the dispensing system comprises a pump provided with a nozzle 5 which is inserted sealingly into the housing 3.
- the pump comprises a sleeve 6 for mounting on the neck 7 of a bottle containing the liquid, said sleeve comprising an upper bearing surface 8 in which the aspect skirt 2 of the push button is mounted in translation.
- the pump shown comprises a body 9 which is mounted in the sleeve 6, said body housing the dosing and liquid compression means which comprise a piston 10 mounted around the nozzle 5 via a spring 11.
- the body 9 also integrates the spring 12 for returning the translation of the nozzle 5 as well as the valve 13 for admitting the liquid into the body 9 via a plunger tube 14.
- the dispensing pump shown is of conventional construction for supplying the nozzle 5 and therefore the dispensing path in liquid under pressure by manual movement of the push button.
- the invention is not limited to a particular type of pump and, in the case where the liquid is packaged under pressure in the bottle, a manually operated valve may be used as a dispensing system.
- the body of the push button has an annular housing 15 of axis perpendicular to that of the mounting housing 3, the downstream end of the distribution path opening into said housing. More specifically, the distribution path is formed in the housing 3 and at least one downstream channel 16 is formed at the bottom of the annular housing 15 for communicating the housings 3, 15.
- the push button also comprises an insert 17 which is associated in the body 1 so as to form a distribution chamber 18 between said insert and said body, more precisely in the free space which is formed at the interface between said insert and said body.
- the distribution chamber 18 comprises convergent channels 19 each towards a dispensing orifice 20, said channels convergents being arranged to allow the impingement of the liquid jets distributed by said orifices to form the desired aerosol.
- the insert 17 and the body 1 each comprise an imprint which has a frustoconical geometry, said geometries, respectively male and female, being arranged so as to be nested one inside the other forming the convergent channels 19 between them.
- the convergent channels 19 are obtained by cooperation of shapes that are simple to perform by molding, in particular by not including any groove.
- the identity and the perfect convergence of the channels 19 are provided geometrically, as well as the convergence angle that corresponds to that of the frustoconical geometries.
- the section of convergent channels 19 may be sufficiently large, for example more than 10 000 microns 2 , to exclude any risk of clogging.
- the frustoconical geometries can be respectively polygonal base for one of the footprints and revolution for the other footprint.
- the convergent channels 19 are formed by providing that the geometry of revolution has a radius adapted to come into contact on the faces 21 of the polygonal geometry by forming liquid passages along each of the edges 22 of said polygonal geometry.
- the frustoconical geometries have a similar convergence angle so as to form convergent channels 19 of substantially constant section.
- the female geometry can be frustoconical polygonal base, the male geometry being frustoconical of revolution, although the reverse construction can be considered.
- the female geometry is frustoconical with a four-sided base to form four convergent channels 19.
- the convergence angle of the frustoconical geometries is such that the channels 19 converge at an angle C of the order of 70 °, so as to produce the aerosol A in the immediate vicinity of the dispensing orifices 20.
- the aerosol A consists of droplets in the air whose size is very uniform and small.
- the section of the envelope of aerosol A is approximately square in shape, however, depending on the nature of the liquid and / or the position of the impingement point, this shape may be more rounded.
- the insert 17 may be arranged to form the dispensing orifices 20 recessed relative to the front face 23 of the push button, so as to bring the impaction point p of said face.
- the insert 17 may be arranged to form the dispensing orifices 20 recessed relative to the front face 23 of the push button, so as to bring the impaction point p of said face.
- the polygonal base may comprise a different number of sides 22 knowing that the number of convergent channels 19 formed will be equal to said number of sides 22.
- six sides can be used to form a substantially round aerosol or two sides to form a substantially flat aerosol.
- the distribution chamber 18 also comprises an upstream annular duct 24 which is in communication with the downstream channel 16 of the distribution path.
- the housing 15 comprises a central stud 25 which extends from the rear wall of said housing having an opposite end 26.
- the insert 17 has a chimney 27 for mounting which is delimited by a front wall 28 , said insert being mounted in the housing 15 around the stud 25 so as to form the annular conduit 24 between the inner wall of the chimney 27 and the outer wall of the stud 25.
- the chimney 27 has an internal geometry which is cylindrical of revolution, the insert 17 being arranged collinearly with the axis of the housing 15 to allow lateral spraying of the liquid relative to the body 1 of the push button.
- the outer face of the rear edge of the chimney 27 is provided with a radial projection 29 anchoring in the housing 15.
- the distribution chamber 18 shown also comprises radial supply channels 30 which are in communication on the one hand with the upstream annular duct 24 and on the other hand respectively with a convergent channel 19.
- the inner face of the front wall 28 is provided with a circumferential alternation of recesses 31 and complementary projections 32 which, by sealing the projections 32 on the front end 26 of the stud 25, is arranged to form a supply channel 30 in each of said recesses .
- an insert 17 in which a frustoconical female geometry with a square base is formed, said geometry having a central opening 33 in which the distribution orifices 20 of the convergent channels 19 are formed. More specifically, the front wall 28 of the insert 17 is provided with the opening 33 in which the female geometry is formed, the front end 26 of the stud having a projection 34 forming the male geometry being nested in said opening forming the convergent channels 19 ( figure 2 ).
- a supply channel 30 communicates with a convergent channel 19 through an opening 35 which is formed in the female geometry, said supply channels converging from the annular duct 24 towards the opening 35.
- the opening 35 has a radius r1 junction between the supply channel 30 and the convergent channel 19.
- the male projection 34 is formed on the end before 26 of the stud 25 having a junction radius r2.
- the female geometry thus formed thus comprises four faces 21 on which the male geometry comes into tight abutment, said faces being connected by edges 22 along each of which a convergent channel 19 is formed and on each of which an opening 35 opens.
