Description

The present invention relates to the application of a cosmetic or care product, especially on the lips, eyelids or the rest of the face.

We have described in the French patent FR-B-2 727 608 a tip having a plurality of pins and in the center of the application surface a product outlet duct.

The end of this conduit is substantially at the same level as the free end of the adjacent pins.

The product that is lodged between the pins is likely to dry and generate soiling.

Also described in the patent FR-B-2 727 608 aforementioned tips each having several outlets opening out facing openings of a grid

The product is distributed substantially uniformly over the entire application surface through the aforementioned orifices.

We still described in the patent FR-B-2 727 608 a tip having an annular groove and in the bottom of this groove a multitude of orifices regularly distributed, so that the aforementioned groove is filled homogeneously product.

There is the risk with these known tips that the product is brought into excess on the application surface and is driven out of the latter during contact with the surface to be treated.

The invention aims to remedy all or some of the disadvantages mentioned above.

It achieves this through a packaging and application device according to claim 1.

Thanks to the invention, the product can be brought to the application surface, during the first use at least, without the entire groove or cavity in which the orifice opens is filled with product.

Thus, possibly excess product on the application surface can be housed in the region of the throat or cavity not filled with product and not be driven out of the nozzle by the surface to be treated.

In addition, the fact that the orifice opens into a groove or cavity remote from the application surface makes it easier to perform at least partial flocking of the application surface, without fear that the bristles or the adhesive used for flocking does not obstruct the orifice.

The invention thus makes it possible to perform a flocking without it being necessary to reperce the orifice in recovery or to use a removable insert introduced into the orifice during the flocking operation.

In a particular embodiment, the application surface comprises at least one beveled portion.

Thus, the tip may have a shape similar to that of a grape lipstick.

In a particular embodiment, the groove or cavity is flocked at its opening opening on the application surface.

In this way, comfort is increased in the application

Advantageously, the entire application surface is flocked.

The orifice may be eccentric on the tip.

When the application surface comprises at least one bevelled portion, the orifice may be located in the lower portion of said bevelled portion.

In order to bring the product in a preferred manner to the application surface, the groove or cavity may have, between said orifice and the application surface, paths opposing to the product different pressure losses, so that the product follow a preferential path.

Said groove or cavity may have a variable height.

Only one orifice can open into the throat or cavity.

In a preferred embodiment, the tip comprises a first portion and a second portion attached to the first, this second portion defining at least partially the application surface.

The second part can be fixed inside a housing defined by the first part, this housing having a shape complementary to that of the second part.

The groove or cavity can be made at least partially by one or more openings of the second part.

The first and second portions of the groove or cavity may communicate through a space defined between the first and second portions.

Such a space may allow recirculation of the product under the second part, so that the product is less likely to dry or degrade on the tip.

In addition, the product possibly contained in the aforesaid second portion of the groove or cavity, during the recirculation of the product, tends to be sucked by the product flowing in or towards the first portion of the groove or cavity, so that the second portion of the groove or cavity is at least partially emptied and can once again accommodate the product present in excess on the application surface

In addition, the use of two assembled parts facilitates the realization of the flocking coating since one of said parts can be flocked separately more easily, with possibly a lower risk of clogging by the flocking coating or orifice (s) used for product supply.

Preferably, one of the two parts comprises a flocking coating which extends to an edge of this part, the latter being in contact with an unfluffed edge of the other part.

Such an embodiment makes it possible to have a flocking coating having a sharp outline, which is favorable for obtaining a neat makeup.

The first part may comprise an outer annular skirt not flocked.

The two parts can be fixed one into the other by snapping, the two parts preferably comprising sealing means for obtaining a sealed attachment.

Alternatively, the two parts can be fixed to each other by welding, gluing or hot spinning.

In a preferred embodiment, the second part comprises a grid or is constituted by a grid.

The second part advantageously comprises an annular groove or a cavity extending in a closed curve, possibly other than circular.

Preferably, the groove or cavity does not have a narrowing of its section at its outer opening, so as to allow the surface of the skin or the lips to penetrate deeper inside, in order to take the product from it. optionally.

The second part, in a particular embodiment, has a variable height, so as to define a beveled application surface and create a preferential path for the product.

The second part may comprise an element cooperating with the first part to form a valve able to move under the effect of the pressure of the product.

This valve can protect the product, upstream of the nozzle, dirt or oxidation.

The first part may comprise a central part forming a jetbreaker located in or in front of a feed passage of the product. Alternatively, the second part may comprise a jet-blower part, situated opposite a feed passage of the product.

The tip application surface may include a beveled surface and a side surface extending around the beveled surface, said beveled and lateral surfaces being flocked. The application surface may be devoid of reliefs such as pimples.

Advantageously, the orifice (s) through which the product feed passage (s) open into the bottom of the at least one groove (s) are recessed from the application surface by a distance of at least 1 mm. .

The groove or grooves may be relatively wide, two opposite edges being for example more than 1 mm apart, the distance between said edges being preferably chosen so that the surface of the lips or the skin can reach the product contained inside.

The second part can be made of a flexible or rigid material.

The second part can be made in a material different from that used to make the first part. One or more plastics material (s) chosen from the following list may be used to make the first and / or second parts: EPDM elastomer, nitrile, latex, thermoplastic elastomer of PS, PET, PU, EVA, PVC, "Polynorborden" or relatively rigid thermoplastic such as PP, PE, PS, PET, PC, etc.

In a particular embodiment, the flocking coating extends to an edge having corrugations.

In a particular embodiment, the second portion comprises a central portion and a peripheral portion connected by material bridges.

These bridges of material may be non-flocked, especially if they are clearly set back from the application surface.

In a particular embodiment, the second part is off-center with respect to the first, which makes it possible, if necessary, to make a more ergonomic endpiece.

The reservoir can be formed by a body made in one piece with a portion of the tip.

The device may include a piston for exerting pressure on the product contained in the reservoir for distribution.

The reservoir may also comprise a compressible wall for dispensing the product by means of a pressure exerted on it, for example by the user.

The device may further comprise a pump.

The tank can be removable, and then constitute a refill.

When the device comprises a pump, the reservoir is advantageously displaceable relative to the rest of the device, so as to actuate the pump and to dispense a dose of product.

Advantageously, the device comprises a closure cap comprising at least one inner closure member capable of covering the outlet or openings of the product when it is in place on the tip.

The tip may be made with a flocking coating without drilling the orifice after flocking or inserting an insert into this orifice during flocking.

Thus, the manufacture of the tip is relatively simple.

Moreover, by avoiding drilling the endpiece after the flocking has been carried out, it prevents the formation of surface roughnesses or primer separation of the flocking coating, especially when the endpiece comprises a flocked portion which is flexible because made for example of elastomer.

We have shown on the figure 1 a device 10 for packaging and application comprising a tip 11 for the application of the product, a body 18 defining a reservoir 12 containing a cosmetic product P or care and a mechanism 13 for causing the dispensing of a dose of product .

The viscosity of the product P is for example between 0.6 and 17 Pa.s.

The tip 11 has a first portion or base 14 on which is reported a second portion or grid 15, as will be specified below.

The aforementioned mechanism 13 comprises a threaded rod 17 rotating in a bore of the body 18, capable of being rotated by means of a driving wheel 19 located in the lower part of the device 10.

A piston 20 meshes with the rod 17 and can move in translation in contact with the body 18, without the possibility of relative rotation relative to the latter, so that a displacement of the wheel 19 is accompanied by an axial displacement. of the piston 20 and allows to expel a dose of product through a passage 30 provided in the upper part of the body 18.

The base 14 of the nozzle 11 is made in the example described in one piece by molding plastic material with the body 18 in a relatively rigid plastic material, and comprises a tubular skirt 23 surrounding a housing 24 in which is fixed the grid 15.

It is therefore the base 14 which serves to supply the grid 15 with product.

The attachment of the grid 15 to the base 14 can be carried out in various ways without departing from the scope of the present invention.

It can in particular be carried out, as shown in the drawing, by means of a godron 26 made with the grid 15 and which snaps tightly into a corresponding annular groove formed on the inner surface of the skirt 23.

In the example described, the grid 15 comprises a central portion 15a and a peripheral portion 15b, connected by material bridges 15c.

The parts 15a and 15b form between them an annular groove 25 in which the bridges 15c extend, the latter providing between them passages through which the product can pass through the grid 15

The grid 15 has on its outer face 27 a flocking coating 28, which covers over a certain height the lateral surfaces 25a and 25b of the grid 15 delimiting the groove 25, as can be seen on the figure 2 .

The outer face 27 is here flat and extends obliquely relative to the axis X of the rod 17, so that the tip 11 has a generally beveled shape.

In the example described, the bridges 15c are set back from the outer surface 27 and the flocking coating 28 covers the side surfaces 25a and 25b to a height less than the distance between the outer face 27 of the bridges 15c.

To achieve the flocking coating 28, the grid 15 is coated with adhesive on its outer face 27 by partial or total immersion thereof in an adhesive bath, and then hairs are deposited electrostatically on the regions of the grid 15 thus coated with adhesive.

The adhesive used is chosen to have viscosity and surface tension which prevent the formation of films at the openings of the grid 15, so as not to seal them.

The bristles may have diameters, lengths, various natures or substantially identical, depending on the product to be applied.

The bristles may be in particular polyamide, rayon, polyester, viscose or cotton.

The length of the bristles may be 0.5 mm or more, for example.

The flocking coating covers over a certain height the outer edge of the grid 15, as can be seen on the figure 3 .

The grid 15 is supplied with product by the aforementioned passage 30, which makes the housing 24 communicate with the interior of the reservoir 12.

This passage 30 opens through an orifice 30a in the bottom of the housing 24 in line with a lower region 25c of the groove 25.

As a result, when the user turns the knob 19, the product begins to exit through the lower region 25c of the annular groove 25, as illustrated in FIG. figure 4 , and this although there may be a space 33 between the grid 15 and the bottom of the housing 24.

Thus, the user can take out in a non-central location of the outer fascia 27 a drop G of product P, as shown in FIG. figure 5 .

Drop G is here at the lower region of outer face 27.

The annular groove 25 being only partially filled with product P when the latter leaves its lower region 25c, its upper region 25d is able to absorb the product during the spreading thereof on the application surface, as illustrated on the figure 6 .

The fact that the product P comes out on the outer face 27 in a localized manner allows the user to accurately control, before application, the amount of product that will be loaded on the outer face 27.

On the other hand, the risk of the product being in excess on the application surface is reduced by the product absorption capacity of the regions of the annular groove 25 away from that through which the product leaves.

The space 33 can be chosen sufficiently wide to allow some recirculation of the product under the grid 15.

The circulation of the product from the passage 30 to the region 25c of the groove 25 and in the latter tends to create, if the velocity of the product is sufficient, a drive and suction effect of the product contained in the space 33, which thus mixes with the product gaining the region 25c and causes at least partial emptying of the region 25d.

The latter can therefore at each new distribution of the product from the tank 12 accept a certain amount of product present in excess on the application surface, if appropriate.

In addition, recirculation of the product tends to prevent the product from staying too long in the mouthpiece without being used and does not degrade.

Preferably, the width of the groove 25 is chosen so that the surface of the skin or mucous membranes in contact with the tip 11 at the time of application of the product may slightly deform and plunge into the product possibly contained in the throat, as shown on the figure 7 .

It will be noted that in the example described, the flocking coating 28 extends to the peripheral edge 28a of the grid 15, this edge 28a being substantially in contact with the non-flocked upper end of the skirt 23, which allows to obtain a flocking having a net outline seen from the outside.

It will also be noted that the risk of clogging by the flocking coating of the passage which feeds the application surface is reduced, given the relatively large dimensions of the annular groove 25 and the fact that the orifice 30a is not exposed to the adhesive used to flock the grid 15.

Of course, one can achieve the tip with other configurations without departing from the scope of the present invention.

For example, there is shown on the Figures 8 to 10 a tip 40 having a support portion or base 41 and an insert or grid 42.

The support portion 41 has a lower portion 43 traversed by a central passage 44 communicating with the reservoir containing the product and an upper portion 45 defining a housing 46 in which the attached portion 42 is fixed.

This upper portion 45 is in the form of a tubular skirt of variable height, the upper end of this tubular skirt being substantially tangent to a plane inclined relative to the axis of the tip.

The insert 42 has an outer face 47 for defining an application surface and covered by a flocking coating 48.

The tip 40 has a generally beveled shape.

The attached portion 42 has a central portion 42a and a peripheral portion 42b, connected by material bridges 42c, like the grid 15 described above.

The attached portion 42 is snapped into the housing 46, as in the previous embodiment.

The central portion 42a includes the peripheral portion 42b with an annular groove 49.

The flocking coating 48 extends somewhat in the annular groove 49, coming to cover the edges of the portions 42a and 42b bordering this groove.

During the distribution of the product, the latter exits in a preferred manner from the lower region 49a of the groove 49 because of the lower height thereof, as can be seen in FIG. figure 9 .

The upper region 49b of the groove 49 makes it possible to recover excess product on the application surface 47, as illustrated in FIG. figure 10 .

The central portion 42a acts in the manner of a jetbreaker by its positioning in front of the passage 44.

The flocking coating 48 extends to a peripheral edge 48a of the insert portion 42 substantially at the non-flocked upper end contact 45a of the tubular skirt 45.

We have shown on Figures 12 to 17 various configurations of bits to show that the invention is not limited to the two configurations just described.

It has thus been represented on the figure 12 a tip 60 which has a support portion or base 61 which is here identical to the support portion 14 described above and a grid or insert 62 having a central portion 62a and a peripheral portion 62b joined by bridges 62c.

The gate 62 has lower and upper rungs 62d parallel to the bridges 62c.

The gate 62 defines a plurality of cavities 63a, 63b, 63c and 63d, the bottom of which is set back from the application surface.

The cavity 63a is formed between the peripheral portion 62b and the lower bar 62d.

The cavity 63b is formed between the peripheral portion 62b, the lower bar 62d and the central portion 62a.

The cavity 63c is formed between the central portion 62a, the upper bar 62d and the peripheral portion 62b.

The cavity 63d is formed between the upper bar 62d and the peripheral portion 62b.

An orifice 64 opens into the bottom of the housing receiving the gate 62 to supply the product application surface.

In the example described, this orifice 64 opens into the region 63a above.

All the cavities 63a to 63d communicate with each other under the gate 62.

Excess product present on the application surface may be recovered by one of regions 63b-63d, in a manner similar to what occurs in the previously described embodiments.

The grid 62 is entirely covered on its outer face by a flocking coating, which extends to the unflattened annular skirt of the base 61 which surrounds the grid 62.

We have shown on the figure 13 a tip 70 which differs mainly from that shown in FIG. figure 5 in that the central portion 15a is replaced by a central portion 75a of larger diameter, which occupies the greater part of the application surface.

The outline of the grid, at its junction with the support portion, may be other than circular.

For example, there is shown on the figure 14 a tip 80 having a grid 81 fixed on a support portion 82.

The support portion 82 has a front face 83 beveled and a housing opening on this front face to accommodate the grid 81.

We see on the figure 14 that the grid 81 comprises a central portion 81a and a peripheral portion 81b interconnected by material bridges 81c, the peripheral portion 81b having a flocking coating to an edge 84, which has corrugations and is in contact with a corresponding edge 85 of complementary non-flocked shape of the end face 83.

We have shown on the figure 15 a tip 90 having a support portion receiving a grid 91 having a central portion 91a and a peripheral portion 91b.

The peripheral portion 91b has a flocking coating to its radially outer edge 92, which is in contact with an unpouched edge 93 of the support portion 94.

The peripheral portion 91b has a corrugated edge 95 surrounding the portion 91a

We have shown on the figure 16 a tip 100 having a support portion 101 and an attached portion 102, the latter comprising a central portion 102a and a peripheral portion 102b interconnected by material bridges 102c.

The support portion 101 has a tubular skirt 103 whose upper edge 104 has corrugations.

The insert 102 also comprises a tubular skirt 105, whose lower edge 106 has a shape complementary to that of the edge 104, so that the two edges 104 and 106 come in full contact with one another, as shown on the figure 16 .

The insert 102 has a flock coating on both its end face 108 and its side surface 109.

This flocking coating extends to the edge 106 and contacts the non-flocked edge 104 of the support portion.

Other shapes can be given to the mouthpiece.

The lateral surface of the tip may be non-symmetrical of revolution.

By way of example, there is shown on the figure 17 a tip 110 which has a support portion 111 and an attached portion 112, the latter comprising a lower portion 112a which comes into contact with the support portion 111 and a remote portion 112b, eccentric with respect to the axis of the portion of support 111.

The attached portion 112 has an upper face 113 forming a bevel. The entire outer surface of the insert 112 has a flock coating.

This flocking coating extends to the upper non-flocked edge of the support portion 111.

Various means can be provided for conditioning the product and supplying the application surface with product.

Thus, the piston reservoir and drive screw of the figure 1 can be replaced by the tank with deformable wall shown at figure 18 .

In this figure, there is shown a packaging and application device 120 which comprises a nozzle 121 identical to the nozzle 11 described above and a reservoir consisting of a compressible tube 122.

The base of the nozzle 121 is here made in one piece with the tube but could, alternatively, be constituted by an element attached to the tube.

We can still use, as illustrated on the figure 19 , a pump for supplying the application surface with product.

In this figure, there is shown a device 130 which comprises a body 134 surmounted by a tip 131 carrying a gate 132 similar to the gate 42 described with reference to Figures 8 to 10 , comprising an annular groove 153, and a support portion 133 attached to the body 134.

The body 134 is open at its lower end 135 to receive a refill 136 comprising a reservoir 137 containing product and a pump 138 having a hollow control rod 139

The rod 139 is inserted by force into a housing 140 located in the upper part of the body 134.

This housing 140 communicates through a passage 141 with the bottom of the housing 142 of the support portion 133 in which is fixed the gate 132.

When the pump 138 is at rest, the refill 136 overflows down the body 134.

The user can, by pressing the bottom 144 of the reservoir 137, push the refill 136 towards the upper portion 145 of the body 134 and cause the actuation of the rod 139 and the dispensing of a dose of product.

The product exiting through the upper end of the rod 139 feeds the application surface in a manner similar to that described with reference to the Figures 8 to 10 .

Advantageously, as illustrated on the figure 20 , the device 130 comprises a closure cap 151 which is adapted to be fixed sealingly on the body 134 by snapping for example and which comprises an inner skirt 148, the lower edge 150 is adapted to engage in the annular groove 153 , so as to prevent the exit of the product and to protect from ambient air the product possibly present under the gate 132 and in the groove 153.

Although it is preferable that the surface used for the application of the product be beveled to facilitate the application of the product and the achievement of a neat makeup, it is not beyond the scope of the present invention when the surface of application extends perpendicularly to the axis of the support portion.

The support portion and the grid can be made in many ways without departing from the scope of the present invention.

In particular, it is possible to produce a single-piece jetbreaker with the support part.

The mouthpiece can also be made with a grid having an outwardly convex outer face, as illustrated in FIG. figure 21 , or concave outwards, as illustrated on the figure 22 .

It is also possible to make the end piece with a completely flocked grid, as illustrated in FIG. 11. It can be seen in this figure that the flocking coating extends, on the outer face of the end piece, up to the peripheral upper edge. 155 of the grid, and that this edge is substantially in contact with the corresponding unbroken edge 156 of the support portion receiving the grid.

We can still achieve the tip with a grid not flocked or flocked on only part of its outer surface.

Of course, the invention is not limited to the embodiments which have just been described.

In particular, it is possible to modify the shape of the base or support part and that of the insert or grid part without departing from the scope of the present invention.

In particular, it is possible to combine the various characteristics of the embodiments which have just been described.

The second part of the tip can be made of a flocked foam, for example.
