Definitions

  • the invention relates to a portable dispenser for several fluid products in parallel to constitute a mixture, for example of several cosmetic body care products, in particular facial care, makeup or perfumery, and/or several pharmaceutical products.
  • fluid products liquid products, as well as creams, gels and pasty products which are sufficiently malleable to be distributed using pumps.
  • a dispenser for one or more fluid or pasty products comprising a dispenser body, a dispensing head fixed relative to the dispenser body, comprising two dispensing orifices, and a pumping assembly comprising one two pumps, each connected to one of the distribution orifices, and each provided with a tubular nozzle defining an ejection axis passing through the associated distribution orifice, the ejection axes being parallel to a reference axis of the distributor and spaced apart 'from one another, the nozzles being movable in translation relative to the distributor body parallel to the ejection axes.
  • a rotating intermediate ring is interposed between the head and the body of the distributor.
  • the intermediate ring is guided in rotation and fixed in translation relative to the distributor body around the reference axis of the distributor.
  • a kinematic connection between the rotating intermediate ring and the two nozzles makes it possible to transform a rotational movement without translation of the rotating ring relative to the distributor body around the reference axis of the distributor into a translational movement without rotation of the nozzle.
  • the first pump and the nozzle of the second pump relative to the distributor body parallel to the reference axis of the distributor.
  • This kinematic connection comprises a pusher interposed between the pumping assembly and the rotating intermediate ring, the pusher being linked to the distributor body by a slide connection capable of guiding a translation movement without rotation of the pusher relative to the distributor body.
  • the pusher is capable of pressing on the nozzles of the two pumps when the intermediate ring rotates relative to the distributor body around the reference axis of the distributor.
  • the pusher has two parallel distribution conduits, each for channeling the fluid escaping from one of the nozzles towards the associated distribution orifice.
  • the dispensing head forms a flared cup which allows the user to mix the two fluids in order to obtain the desired final product.
  • the operation of the distributor can be considered satisfactory if neither pump requires priming, or if both pumps require a priming and pressurization cycle. We are then assured that from the first use, the distributor will distribute the two products in the desired proportion. If, on the other hand, only one of the two pumps requires priming, the first pumping cycle will not be satisfactory, insofar as only one product, that from the pump not requiring priming, will be delivered.
  • the ergonomics of using such a dispenser is not entirely satisfactory, to the extent that the user must hold the body or head of the dispenser with one hand and access the ring with the other. intermediate, which is located under the flared head.
  • the device is not suitable for the distribution of products coming from pumps not having the same volume or having different priming characteristics. It is therefore not suitable for the distribution of products with different flow characteristics, for example different viscosities, densities or surface tensions, requiring different types of pumps, or for products one of which is sensitive in contact with air and the other not.
  • the invention aims to remedy at least some of the drawbacks of the state of the art and to propose a portable dispenser with several pumps, suitable for the simultaneous distribution of products having different natures or behaviors.
  • priming cycles the two pumps prime, without distributing fluid. Priming the pump without air intake is, however, faster than priming the air intake pump which must pressurize the fluid reservoir where it immerses.
  • the volume differential between the two distribution conduits makes it possible to compensate for this difference in behavior of the two pumps, by allowing the fluid coming from the pump without air intake to fill the volume available in the first distribution conduit, without escaping. through the first distribution port while the air intake pump completes its priming over one or more cycles.
  • the number of priming cycles for the pump without air intake varies, depending on the initial state of the associated reservoir and the viscosity of the fluid, from 1 to 5.
  • the number of cycles priming of the air return pump is more important, greater than 5 and possibly reaching 10.
  • the pumps are active and distribute the products in the desired proportions.
  • the first conduit comprises an intermediate timing chamber, connected to the distribution orifice by a portion of the second conduit having at least locally a cross section less than 4 mm 2 , preferably less than 2 mm 2 .
  • the passage section is chosen so as to minimize the flow of liquid filling the intermediate timing chamber. The blocking effect is all the more effective if the product delivered by the first pump has a high surface tension or viscosity.
  • the pusher integrates at least part of the first distribution conduit to channel a first fluid escaping from the nozzle of the first pump towards the distribution orifice, and at least part of the second distribution conduit for channeling a fluid escaping from the nozzle of the second pump towards the distribution orifice.
  • the part of the first distribution conduit integrated into the pusher has a volume greater than the part of the second distribution conduit integrated into the pusher, with a difference in volume greater than or equal to the volume delivered by a pumping cycle of the spray nozzle.
  • the first pump preferably greater than twice the volume delivered by a pumping cycle of the nozzle of the first pump.
  • the pusher may be made up of several assembled parts.
  • the pusher comprises at least two parts, preferably each obtained by molding, preferably each able to be obtained by molding in a mold whose parts are movable relative to each other in translation parallel to the reference axis .
  • the desired kinematics are thus obtained with simple geometries, and therefore simple tools.
  • at least one elastomer static seal is provided positioned between the parts of the pusher to ensure the sealing of the conduits.
  • the first distribution orifice is provided with a non-return valve.
  • the non-return valve opposes the circulation of air in the first conduit, and prevents unwanted flow of the product contained in the first conduit.
  • the second distribution conduit is capable of channeling the second fluid escaping from the nozzle of the second pump towards the first distribution orifice.
  • the products distributed by the first pump and the second pump are therefore conveyed to a common distribution orifice, to flow together out of the distribution orifice.
  • the dispensing orifice may open onto a flat, concave or convex surface of the dispensing head. A concave surface forming a bowl will be preferred in particular if the product distributed is relatively fluid, or if it is desired that the user can mix the product(s) distributed before their application.
  • the distributor further comprises a distributor body in which the pumping assembly is housed, the pusher being linked to the distributor body by a slide connection capable of guiding a translation movement without rotation of the pusher relative to to the distributor body, parallel to a reference axis of the distributor, the nozzle of the first pump and the nozzle of the second pump being movable in translation relative to the distributor body parallel to the reference axis.
  • This guidance method is particularly simple. Other guidance modes can, however, be considered. In particular, it is possible to provide a pivoting movement of the pusher relative to a pivot axis perpendicular to the translation axes of the first pump and the second pump.
  • the distributor further comprises a dispensing head movable relative to the distributor body, and a kinematic connection between the dispensing head and the pusher to transform a movement of the dispensing head relative to the distributor body in a translation movement of the pusher relative to the distributor body parallel to the reference axis of the distributor.
  • the movement of the dispensing head can for example be a translation movement without rotation, or a helical movement.
  • the dispensing head is movable in rotation around the reference axis of the distributor and fixed in translation, relative to the distributor body.
  • the kinematic connection between the distribution head and the nozzle comprises an annular guide track located at a distance constant of the reference axis of the distributor and having one or more undulations in an axial direction parallel to the reference axis of the distributor and a set of one or more sliding surfaces cooperating with the annular guide track, the track of annular guide and the assembly of one or more sliding surfaces being arranged in such a way that a rotation of the distribution head around the reference axis of the distributor causes a relative translation between the annular guide track and the set of one or more sliding surfaces parallel to the reference axis of the distributor, combined with a relative rotation between the annular guide track and the set of one or more sliding surfaces around the reference axis of the distributer.
  • the annular guide track is continuous and makes it possible to make a complete revolution of the dispensing head around the reference axis of the distributor. This continuity allows the user to use the distributor without worrying about any initial position.
  • the position of the pumping assembly and of the kinematic connection between the distribution head and the nozzle reached after one revolution is identical to the starting position and corresponds to an integer number of pumping cycles, number which can be greater than or equal to one.
  • the annular guide track and all of one or more sliding surfaces are arranged in such a way that the dispensing head can rotate around the reference axis of the distributor in a direct direction and in a retrograde direction, preferably over more than one turn.
  • the desired transformation of the rotational movement without translation of the dispensing head into a translational movement without rotation of the nozzle is thus obtained in both directions of rotation of the dispensing head.
  • the exterior wall of the distributor crossed by the distribution orifice is a wall of the distribution head.
  • the distribution head therefore serves both to initiate the pumping movement and to collect the products distributed by the distributor.
  • the first distribution conduit can be provided and the second distribution conduit comprise a common chamber of variable height measured parallel to the reference axis, s extending between the pusher and the first distribution orifice.
  • This common chamber has a variable volume and allows the two products distributed by the two pumps to accumulate before they flow out of the common distribution orifice.
  • the common chamber is delimited by two cylindrical sections (67, 110) capable of sliding one into the other parallel to the reference axis of the distributor and of rotating one relative to the the other around the reference axis of the distributor, one of the two cylindrical sections being fixed relative to the dispensing head, the other of the two cylindrical sections being fixed relative to the pusher.
  • the common chamber is delimited by a deformable wall, for example an accordion wall, having a first end fixed in translation relative to the dispensing head and a second end fixed in translation relative to the pusher.
  • the common chamber is sealed by an annular seal bearing against a seal seat, and able to rotate relative to the annular seal seat when the head distribution rotates relative to the distributor body around the reference axis.
  • the nozzles of the two pumps preferably have an identical useful stroke.
  • one of the two pumps has a shorter useful stroke than the other, in which case we can provide a dead stroke of the pusher before the pusher comes to rest on the nozzle of the pump whose useful stroke is the shortest.
  • the distributor body comprises a wall delimiting a peripheral reservoir into which a pump body of the second pump opens, the pump body of the first pump diving into another variable volume tank preferably housed inside the peripheral tank.
  • the wall of the peripheral reservoir can be opaque or transparent.
  • the inner tank can be opaque or transparent. The transparency of the walls makes it possible to visualize the levels of fluids contained in the tanks.
  • the two ejection axes are offset relative to the reference axis.
  • the three axes can be coplanar to optimize the direction of the resulting force on the pusher, or not.
  • the pumping assembly comprises at least a third pump, comprising a tubular nozzle defining a third ejection axis fixed relative to the distributor body and parallel to the first ejection axis, the nozzle of the third pump being movable in translation relative to the distributor body parallel to the third ejection axis, the pusher being able to press on the nozzle of the third pump when the distribution head rotates relative to the distributor body around the reference axis of the distributor, and comprising a third distribution conduit for channeling a fluid escaping from the nozzle of the third pump towards the distribution orifice.
  • the three ejection axes can be coplanar, or form an isosceles triangle, or even equilateral, to minimize space requirements.
  • the three pumps can immerse in three separate enclosures to pump three distinct fluids corresponding, where applicable, to three distinct products to be mixed.
  • two of the three pumps can immerse in a common enclosure, which allows, for a given stroke of the pusher, to obtain very different proportions for the fluid delivered by a single pump and for the fluid delivered by two pumps in parallel.

  • the descent of the pusher 82 is accompanied by an enlargement of the volume of the chamber 118, which fills with the products ejected through the outlet orifices of the lights 114A, 114B.
  • the rise of the pusher in the residual part of the rotation to the final indexed position is accompanied by a reduction in the volume of the chamber 118 and an ejection of the mixture of products contained in the chamber 118 by the anti-valve. -return 104.
  • the user can then collect the dose of the two mixed products at the level of the cup 64.
  • the volume VA of the timing chamber 122A and the volume VB of the common conduit 122B should be dimensioned in such a way that the difference in volume VA-VB between these two volumes is equal to the volume delivered by a 16A pump pumping cycle.
  • variable volume chamber 118 it is advantageous for the maximum volume of the variable volume chamber 118 to be greater than or equal to the sum of the volumes delivered by the three pumps 16A, 16B, 16C during a pumping cycle. This ensures that the ejection of the contents of the chamber 118 by the non-return valve 104 only begins in the second part of the pumping cycle, when the pusher 82 rises.
  • a pumping cycle over a half-turn is preferably independent of the direction of rotation of the distribution head 22, which can be either direct or retrograde.
  • appropriate symmetries are provided for the guide tracks 80 and 88.
  • nothing prevents the user to turn the dispensing head 22 always in the same direction, therefore over more than one turn, each half-turn corresponding to a pumping cycle.
  • the number of pumps and tanks may vary. For example, there may be only one air return pump and one pump without air return. We can also consider three pumps immersed in three different tanks, including at least one air intake pump and one pump without air intake. We can also consider embodiments with three pumps whose axes 200A, 200B, 200C are coplanar. Providing more than one pump for a given reservoir makes it possible on the one hand to increase the dose delivered for a given translation stroke of the pusher 82, and on the other hand to balance the forces on the pusher 82.
  • the useful strokes of the pumps can be identical, or different.
  • the pusher it is possible, for example, for the pusher to be integral with the nozzle having the greatest useful stroke, and for the nozzles of the other pumps to be mounted sliding in the tubular sleeves 94A, 94B, 94C of the pusher.
  • the fixing of the pump(s ) 16A, 16B, 16C to the body 12 of the distributor 10 can be carried out by any appropriate means.
  • the general shape of the body 12 of the distributor may vary.
  • the dispensing head 22 is preferably cylindrical, but other choices can be made, in particular a dispensing head having a revolution symmetry of order N around the reference axis 100, N a number integer for example equal to the number of pumping cycles obtained on one revolution of the distribution head 22.
  • the deformable pocket 156 can be replaced by a piston sliding on the walls of the barrel 32 and separating a variable volume into which the pump 16A immerses from an environment outside atmospheric pressure, as illustrated for example in the application
