EP1557110B1 - Device for dispensing at least two products and dispensing nozzle - Google Patents

Abstract

The device has an applicator nozzle (1) with product distribution orifices (16, 17, 24-26), where each orifice is in fluid communication with one of two compartments (3, 5) containing two hair coloring products. The nozzle has an inner distributor dividing flow of products from the compartments, so that the orifice (16) dispenses a mixture of two products in a proportion different from that of the mixer dispensed by the orifice (17).

Description

The present invention relates to an applicator tip capable of dispensing at least two products, this nozzle being particularly useful for application of hair dyes in locks on a hair. It also relates to this applicator tip operatively mounted on containers containing products to be dispensed to then form a device for packaging and application of at least two products.

In the state of the art are known sets proposing a separate packaging of two products while ensuring their joint distribution, to achieve a composition, including cosmetic, as used for example in the field of hair dye. This type of assembly makes it possible, in particular, for the extemporaneous mixing of the two products (a dye and an oxidant) which, for reasons of stability, are kept apart from one another until the moment of formation of the composition. staining.

In particular, examples of this type of assemblies described in the documents are known. US-2003-0121936 and US-2003-0019883 .

From the teaching of the document US 2446398 comb-shaped tips having an inner channel opening through a plurality of outlets are also known, these outlets being provided between teeth of said comb. The channel of such a comb is fed with products to be dispensed by mounting the nozzle on a handle comprising several reservoirs, the tanks respectively comprising said products. One channel input, upstream of all outputs, receives the product streams from each of the compartments. A mixture is then made at this inlet of the channel, and this homogeneous mixture is distributed at the outputs.

Thus, when a user wishes to make locks on her hair, it can by means of devices known in the state of the art make wicks from the same dye composition formed extemporaneously upstream or downstream of the tip of distribution, and achieve, in this case, locks of identical hue on the hair. Variations of tone of these locks can nevertheless be obtained by controlling in a very precise way the times laying respective mixture on the different locks. The creation of degraded locks on the whole of the hair then becomes very complex, especially when the user realizes her locks herself. With these known devices, it is also impossible to simultaneously produce strands of colors, not just different colors.

For such use, there are known tips having a plurality of inner channels each opening at a separate outlet. For example, document teaching US 6012462 there is known a portable assembly, for example in the form of a gun, comprising four containers each having a different coloring product. This assembly is mounted such that each container is in fluid communication with one or more channels of the comb so that each of the products contained in the containers are distributed distinctly at the level of at least one or even several separate orifices.

But with such a portable set, the user who wishes to achieve degraded locks must have purchased or prepared itself the coloring compositions contained in the containers so that these compositions are different colors but close to each other. Moreover, the portable set will not allow him to expand the palette of colors that can be made on his hair, except to change the structure of the set, the modified set would then include containers added, and as much if not more additional channels and dispensing ports.

There is a need, not satisfied by the devices of the state of the art, of a device making it possible to produce degraded wicks and of different shades without requiring the use of as many reservoirs as there are different shades. achieve. There is also a need for a device which makes it possible to easily achieve intermediate hues of wicks which can be made directly from commercially available hues.

2. ii) l'embout comporte un répartiteur intérieur divisant les flux de produits provenant respectivement des compartiments, de manière à ce qu'un premier orifice distribue un premier mélange de premier et deuxième produits dans des proportions différentes de celles d'un second mélange de ces produits distribué par un deuxième orifice.

The device for packaging and applying at least two products, in particular hair treatment products, according to the invention aims to meet these expectations by proposing a device comprising

• a first compartment adapted to contain a first product,
• a second compartment adapted to contain a second product, and
• an applicator tip comprising at least two product dispensing orifices, the nozzle being mounted in such a way that each orifice is in fluid communication with at least one of the compartments,

characterized in that

1. i) at least one of the dispensing orifices is in fluid communication with the first and second compartments, and
2. ii) the nozzle comprises an internal distributor dividing the product streams respectively from the compartments, so that a first orifice distributes a first mixture of first and second products in proportions different from those of a second mixture of these products distributed through a second orifice.

The advantage of the invention is to be able to use such a device to dispense for example two hair coloring products, and thus allow an application of a color gradient varying from a first color corresponding to the first pure product, to a second color corresponding to the second pure product. The coloration thus produced has a natural effect, and can be obtained in a minimal time from the first application of the products.

In particular, the device according to the invention makes it possible to distribute via the first orifice a first non-zero proportion of the flow of first product and a second non-zero proportion of the flow of the second product, the complementary proportions of the streams of first and second products being distributed via the second port.

For example, the proportion of one of the products of one of the two mixtures may be zero.

Advantageously, the nozzle may comprise at least three orifices such that a first orifice is in fluid communication with the first container only, a second orifice is in communication with the first and the second container respectively, and a third orifice is in communication with the first container. the second container only. There are thus three distinctly emitted tints out of the mouthpiece, while only two dyes are separately contained in the containers.

Preferably, the tip may comprise a chamber divided into at least two zones by the distributor, inputs respectively connected to the containers and feeding these zones, and outputs, each in communication with a dispensing orifice, each zone comprising at least one exit.

In this case, a first zone may comprise at least two outputs of distinct sections, each of these two outputs opening into a separate orifice. Additionally, a second zone may comprise at least two outputs of distinct sections and relative proportions different from the relative proportions of the two outputs of distinct sections of the first zone, each of these two outputs opening into a distinct orifice.

For example, the inlets may open at a lower face of the chamber, an upper face of this chamber having outlets. According to this example, the splitter can extend at least partly orthogonally to the underside. Still according to this example, and in addition, the splitter can also extend at least partly orthogonal to the upper face.

According to a particular embodiment of the invention, the chamber is parallelepipedic and the distributor extends along a diagonal of the parallelepiped.

Advantageously, the tip may comprise teeth, for example arranged so as to form a comb. In this case, one of the orifices may open into a hollow formed between two teeth. Alternatively, an orifice may open into an end portion of a tooth. And more particularly, the orifice may open laterally relative to the terminal portion of a tooth, towards a space defined between two adjacent teeth. Preferably, the compartments each have a main axis of elongation, these axes being in particular parallel to each other, so that the teeth extend either in parallel or in a secant surface, and in particular perpendicular to one another. less axes of principal elongation.

Preferably, the device may comprise an assembly within which are placed the two containers, such that the tip is retained on this assembly in communication with the containers.

Advantageously, the containers comprise means for dispensing the products they contain. For example, one of the containers may comprise manually compressible walls so as to allow the product contained in the mouthpiece to come out under the effect of a stress applied to an outer periphery of these walls. Alternatively, one of the containers may comprise a piston disposed in a bottom of the container and whose rise in the container allows the supply of the tip product. Advantageously, the two containers are equipped with a piston, which allows to distribute the products repeatedly and identically in both areas.

Preferably, the first product is a first hair dye, and the second product is a second hair dye distinct from the first, the two products being intended to be applied to the hair.

Where appropriate, the tip may comprise at least three inputs to be respectively connected to at least three containers. In this case, the chamber can be divided into three zones by the splitter, each zone being respectively fed by an input. As a variant, the mouthpiece has three inlets opening into two zones such that a first zone receives the entirety of the first product and a proportion of the second product, while the second zone receives the entirety of the third product and the complementary proportion of second product.

1. i) au moins l'un des orifices de distribution est en communication fluidique avec deux zones, et en ce que
2. ii) le répartiteur intérieur est disposé de telle sorte le flux de produits arrivant respectivement par les entrées est divisé via les sorties de manière à ce qu'un premier orifice distribue un premier mélange de premier et deuxième produits dans des proportions différentes de celles d'un second mélange de ces produits distribué par un deuxième orifice.

The subject of the invention is also an applicator tip capable of dispensing at least two products, said nozzle comprising a chamber divided into at least two zones by an internal distributor, the zones being fed with said products via supply inlets, each zone having at least one outlet, the nozzle comprising at least two dispensing orifices each in fluid communication with at least one outlet,
characterized in that

1. i) at least one of the dispensing orifices is in fluid communication with two zones, and in that
2. ii) the inner distributor is arranged in such a way that the flow of products arriving respectively through the inlets is divided via the outlets so that a first orifice distributes a first mixture of first and second products in proportions different from those of a second mixture of these products distributed by a second orifice.

For example, a first zone may have two outputs, while a second zone has an output.

Advantageously, the tip has three dispensing orifices. Alternatively, the tip may comprise a plurality of dispensing orifices.

For example, a first report of a section of a first output in communication with a first zone on a section of a second output in communication with a second zone, this first output and this second output supplying a same first distribution port , is distinct from a second ratio of a section of a third output in communication with the first zone on a section of a fourth output in communication with the second zone, this third output and this fourth output supplying a second port of separate distribution of the first dispensing orifice.

Even according to this example, an output can be closed and therefore of zero section. In this case, section reports can have a finite or infinite value.

Advantageously, a first zone comprises at least two outputs of distinct sections, each of these two outlets opening into separate orifices. In this case, a second zone may comprise at least two outputs of distinct sections and of different relative proportions of the relative proportions of the two outputs of distinct sections of the first zone, each of these two outlets opening into separate orifices.

According to a particular embodiment, the inlets open at a lower face of the chamber, an upper face of this chamber having outlets. The distributor then preferably extends at least partly orthogonally to the lower face, and possibly at least partly orthogonal to the upper face. More particularly, the chamber may be parallelepipedal, and in this case, the distributor extends along a diagonal of the parallelepiped.

Alternatively, an orifice may open into an end portion of a tooth. And more particularly, the orifice may open laterally relative to the end portion of a tooth, towards a space defined between two adjacent teeth.

Alternatively, the tip may comprise at least three inputs to be respectively mounted on at least three containers, these inputs opening into a chamber divided into at least three areas by the distributor, each of the areas being respectively fed by an input.

The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are presented only as an indication and in no way limitative of the invention. The figures show:

The figure 1 shows a dispensing nozzle 1 having a first inlet 2 mounted on a first container 3, and having a second inlet 4 respectively mounted on a second container 5. The containers 3 and 5 respectively comprise openings 6 and 7, such as the first opening 6 is in fluid communication with the first inlet 2, while the second opening 7 is in fluid communication with the second inlet 4. Preferably, the nozzle 1 is sealingly mounted on these containers.

Containers 3 and 5 contain products, preferably differing from one another, which can be fed via openings 6 and 7 into endpiece 1. For example, containers have means for driving out products. to the tip 1.

According to a first variant, at least one wall of a container is flexible and can be manually depressed so as to create an overpressure in the container enclosure and thus cause the product to exit. In the example shown, the containers 3 and 5 are contiguous. In this case, and according to the first variant, the two containers are then preferably identical, and form for example two flasks with flexible side walls.

According to a second variant, a container comprises means for driving the outlet of the product it contains, for example by using a piston provided or not with a means for driving the external piston to the container.

For example, the two containers 3 and 5 may correspond to two compartments formed in the same assembly, and in this case the tip is directly mounted on said assembly.

Figure 1 the two containers 3 and 5 are identical and cylindrical and the openings 6 and 7 are orthogonal to the axis of elongation of these cylinders. The inlet 2 of the endpiece is extended by a channel of variable section to have an end 8 adapted to be sealingly mounted on the first opening 6, while the inlet 2 is defined at the opposite end of this channel , and can thus be of different section. For example, the second input 4 is connected in the same way to the second opening 7.

The inlets 2 and 4 of the mouthpiece 1 open into a chamber 9 of the mouthpiece 1. This chamber 9 has a special internal structure insofar as it makes it possible to keep separate the flows of products arriving respectively from the two receptacles via the entrances 2 and 4. Indeed, it comprises a distributor 10, Figure 2 , being in the form of a partition dividing the space of this chamber into two zones 11 and 12, and such that an inlet opens into a single zone. In this case the first inlet 2 opens into the first zone 11 and the second inlet 4 opens into the second zone 12.

According to figure 2 , the chamber 9 has a generally parallelepipedal shape, and the distributor 10 extends along a diagonal of the face having the two inputs 2 and 4. The inputs are preferably arranged near the base of the triangular section of their respective zone , partially delimited by the distributor 10. The location of this input is defined so that when the area is supplied with product, the product can flow throughout the space of this area, to chase any presence of air in the area.

Each zone has at least one exit to let the product out to the level of dispensing orifices of the nozzle. In this case, the first zone 11 has a first output 13 and a second output 14. The output 13 is connected by a first channel 15, Figure 3 at a first dispensing orifice 16, while the second outlet 14 is connected independently via a second channel 19 to a second dispensing orifice 17. Furthermore, the second zone 12 also has an outlet 18, this outlet 18 opening into the second channel 19 leading to the second dispensing orifice 17, while the same second zone 12 has no outlet allowing it to open into the first channel 15 leading to the first dispensing orifice 16. Thus, the first dispensing orifice 16 delivers the product contained in the first container 3, while the second dispensing orifice 17 delivers a mixture of the products of the two containers, the mixing of the products taking place in particular in said second channel 19.

The first orifice 16 thus distributes a proportion of 100% of the first product, and zero of the second product, while the second orifice 17 distributes non-zero proportions of each of the two products. The proportion of the two products distributed by this second orifice 17 depends on the proportion in which the second channel 19 is fed with each of two products.

Considering the view of the figure 3 as a schematic, it may be considered that the apparent sections of the outlets 14 and 18 are equal to the sections of the arrival openings 20 and 21, respectively, in the second channel 19. Moreover, this situation corresponds to that shown in FIG. Figure 4 . In this case, the respective proportions of the products are directly correlated to these respective sections. The proportion of first product exiting through the second orifice 17 corresponds to the ratio of the section of the outlet 14 to the sum of the sections of the outlets 14 and 18, the complementary proportion corresponding to the second product.

But alternatively, it can be provided that an output such as 14 and 18 opens into an intermediate channel of variable section to then open into said channel 19. In this case, then, to determine the future proportion of the distributed product, it is necessary to consider the smallest of the sections of the intermediate channel, between the exit and the arrival opening.

In any case, with a nozzle according to the invention, and such an internal distributor 10, it is possible to deliver mixtures of all proportions of the two products respectively feeding the two zones 11 and 12.

Preferably, the tip 1 has more than two dispensing orifices. For example, according to Figures 1 to 4 , the tip 1 has five orifices such as orifices 16 and 17. In the example shown, an orifice is at most supplied by two orifices each coming from a distinct zone.

For example, the tip 1 comprises a plane of symmetry so that each zone has as many outputs, the outputs of one zone being symmetrical to that of the other zone. More precisely, the first zone 11 has a third output 22 and a fourth output 23. In a symmetrical manner, the second zone 12 also has four outputs, ie three outputs in addition to the output 18. These outputs are arranged in such a way that the orifices farthest from each other of the nozzle distribute only and respectively one of the products, and such that the three orifices arranged between these remote orifices distribute mixtures of these two products.

According to the example of Figures 1 to 4 , the dispensing orifice 16 has a symmetrical dispensing orifice 24, these two orifices being furthest apart from each other. The dispensing orifice 17 has a symmetrical dispensing orifice 25, and the last dispensing orifice 26 of the five orifices provided is preferably defined on said axis of symmetry. The dispensing orifice 17 distributes a proportion A of the first product and a complementary proportion of the second product. As a result, the symmetrical orifice 25 distributes a proportion A of the second product for a complementary proportion of said first product. According to the embodiment, the central dispensing port 26 dispenses a half / half mixture of first and second product.

Obviously any other internal configuration of the nozzle is also within the scope of the present invention, regardless of the number of more than two orifices provided. Furthermore, by playing with the dimensional and the number of outputs provided by zone, it is possible to achieve an infinite number of nozzle variants according to the invention. Alternatively, the position of the splitter 10 within the chamber 9 may also allow any product to be dispensed at any orifice.

Thus, it is possible to extract as many different mixtures from two products as there are distinct dispensing orifices, each orifice being fed in proper proportions, and therefore possibly different, into these two products. Optionally it can provide to close some of the dispensing orifices, if certain proportions of mixtures are not desired.

Figures 4 and 5 according to a particular embodiment, the chamber 9 is parallelepipedal, the inputs 2 and 4 are defined at a lower face 27. As can be seen from FIG. figure 4 these inlets open in such a way that the product flows arrive orthogonally at this lower face 27 inside the chamber 9. The outlets 13, 14 and 18 are defined at an upper face 28, opposite to the The distributor 10 forms a partition extending along the respective diagonals of this lower face 27 and of this upper face 28. Preferably, it extends along diagonals parallel to each other of these two faces.

In particular, the outputs of the zones are extended by intermediate channels such as 29 extending orthogonally to the upper face 28, to open into a first portion 30 of a channel such as 15 or 19. This first portion 30 extends orthogonally to the intermediate channel 29, and therefore parallel to the upper face 28. This first portion 30 is extended by a second portion 31 of said channel such as 15 or 19, at which is defined the dispensing orifice such as 16, 17 , 24, 25 or 26.

In the embodiments shown in Figures 1 to 7 channels such as 15 or 19 have an elbow. In particular, they are all bent according to the same angle so as to have their dispensing orifice respectively aligned in one or more rows. The second portion 31 then extends in particular orthogonally to the first portion 30. It is then defined in the extension of the respective principal elongation axes of the two containers.

Alternatively, the second portion 30 has an additional bend or a piece across this portion forming a mixing obstacle. The mixing obstacle, for example in the form of a helix, or the additional bend contribute to create turbulence in the laminar flow of the products inside the channel. This turbulence contributes to a homogeneous mixture of the two products, so that the products are intimately mixed when they exit at the dispensing orifice.

Alternatively, according to the embodiment of the Figure 8 , the channels such as 15 or 19 are rectilinear, and the first portion 30 is extended in the second portion 31 which is collinear. The second portion 31 is then secant with the respective main elongation axes of the two containers, which facilitates the handling of such a device provided with such a tip. In particular, the second portion is perpendicular to said axes of the containers.

In the example presented Figure 4 , the second portion 31 of a channel such as 19 preferably extends inside a tooth 32 extending from the outer periphery of the tip. Preferably, each channel extends within a separate tooth. Thus the tip comprises a series of teeth for example arranged to form a comb.

The teeth of such a comb form pallets at the figure 6 , while Figure 7 the teeth are in the form of tubular pins. Figure 6 , a pallet comprises a dispensing orifice such as 16 defined at a wall 33 of the outer periphery of the pallet. The dispensing orifice 16 is preferably defined at a distance from the borders of this wall, and thus opens at a space defined between two juxtaposed pallets. Indeed, the pallets are arranged parallel to each other so as to form said comb. Given the width of the pallets, when we pass such a comb in the hair, a wick is taken between two pallets and spreads out so as to form a plane. The dispensing orifice thus opens onto part of the wick taken between these two pallets. It is thus possible to make a veil of fine wicks, with an easy comb to handle.

In a variant, figure 7 , the dispensing orifices such as 16 and 17 are defined in the axis of elongation of the teeth and open respectively at an end portion 34 of the second portion 31. Optionally, each dispensing orifice is surrounded by small spikes 35 delimiting the dispensing orifice and extending along the main axis of elongation of each of the teeth such as 32. These pins 35 can be obtained injection in one piece with the tooth 32 which carries them. Preferably, they are thin so as to be flexible and thereby facilitate the spread of the product on the lock of hair taken in these pins 35. Thus fine locks can also be taken in these pins, which defines the width wicks that can be made. These pins participate in the impregnation of the product mixture distributed by the dispensing orifice on the lock taken in the pins. Altematively, according to an example not shown, the orifices may be defined in a recess 36 opening between two teeth of a comb.

According to the variant presented Figure 8 , the tip 1 comprises teeth such as 32 whose dispensing orifice is respectively delimited by an arrangement of pins such as 35, these teeth being arranged such that they define a row such that between at least two teeth consecutive, an arrangement of teeth such as 36 is presented. This arrangement of teeth such as 36 does not have a dispensing orifice, it is intended to allow the styling of the hair arranged between two locks of hair coated via the dispensing orifices.

Preferably, the free ends of the teeth such as 36 are aligned with the free ends of the pins such as 35. Thus the depth at which hair can be taken between two teeth such that 36 is greater than the depth defined between two pins. such as 35. When the tip 1 is moved along the hair, a first curtain formed wicks selected to be coated is placed in a different plane from the plane in which extends the curtain formed by the mass of hair not to be coated and taken in the teeth such as 36. The locks are thus better separated from the rest of the hair.

The spacing between the wicks produced is a function of the spacing provided between the teeth. The closer the teeth are to each other, the more tight the locks will be. For example, the teeth may be so tight that they make it possible to make wicks juxtaposed with each other without intermediate wicks not coated with product. This gives a continuous and degraded veil. Alternatively, and to obtain a more natural effect, the spacing between two consecutive teeth is not constant.

In particular, according to the example of figure 7 the chamber 9 is defined inside a cylinder. Any other structure can also be considered.

According to the example of the figure 6 , the tip can be connected to three tanks, and can thus be fed in three different products. Indeed, the tip has a third input 102. For example, the three products are then mixed in two areas, in which case one of the three products can feed the two areas, the other two each supply respectively a zone. Alternatively, the chamber can be divided into three distinct zones by a suitable shaped distributor, each product respectively supplying a zone. It is thus possible to release even more different mixtures from these three products. One can even achieve a rainbow effect by multiplying the number of zones defined in the chamber, each zone being fed at least from a product different from those supplying the adjacent zones.

Throughout the description, the expression "comprising a", and its numerical equivalents greater than one, should be understood as being synonymous with "having at least one", unless the opposite is specified.
