EP2156763B1 - Device for packaging and applying a product - Google Patents

Abstract

The applicator (1) to prepare an apply a product, especially a cosmetic skin cream, has a handle (5) with a two-part container for the product. The container parts are of different materials. The second part (20) of the container, which can be rotated around an axis (X) in relation to the first part (10), has at least one surface in contact with the product in the container, so that its rotation applies a pressure moving the product towards the applicator e.g. a foam pad. The appliance also incorporates a mirror (90).

Description

The present invention relates to devices for packaging and applying a product, in particular a cosmetic or a care product.

The German patent application DE 31 00529 A1 describes a device for packaging and dispensing a creamy product having two parts rotatable relative to each other and a chamber containing the product, formed inside the device, the rotation of one of the parts relative to the other causing a decrease in the volume of this chamber and the distribution of the product directly through an outlet port. Such a device is devoid of applicator.

We know by the patent US 3,085,281 a nail polish container comprising a paddle stirrer rotatable by the user through a knob in the lower part of the container.

The European patent application EP 1 177 741-A1 discloses a container having an agitator rotatable by the applicator shaft.

French patent FR 1 374 719 describes a similar container.

The patent application US 2002/0007839 discloses a packaging and application device comprising a piston engaged on a screw driven in rotation by the user. The pressure exerted on the product is due to the axial displacement of the piston, which must not rotate relative to the body of the container to be driven by the screw.

Also known are devices for packaging and applying mascara comprising an applicator comprising a brush mounted at the end of a rod whose other end is secured to a closure cap of the container also constituting a gripping member . The container has a generally elongated, relatively narrow shape, so that the brush can take most of the product contained in the container. With such a device, however, a certain amount of product is never removed by the brush and is lost after a chimney has formed in the product.

The invention aims to meet all or part of the above needs.

The object of the invention is, according to one of its aspects, a device for packaging and applying a product, according to claim 1.

The applicator can be loaded into product by the relative rotation of the first and second parts.

This product movement can take place in certain embodiments around and / or through the applicator, in one direction or in several directions, for example alternately in two opposite directions. Said surface is preferably configured such that substantially all the product contained in the container can be used. Product movement to the applicator can thus advantageously take place until substantially complete emptying of the container.

In non-limiting examples of implementation of the invention, the device may comprise an anti-rotation system that allows rotation of the first part relative to the second part only in one direction. This anti-rotation system may for example comprise at least one elastically deformable tab carrying a tooth moving in contact with notches.

The tab is for example made with one of the first and second parts and the notches with the other of the first and second parts.

The applicator may be removable or not. When the applicator is removable, it can be made integral with the container in the absence of use, and can advantageously contribute to the closure thereof.

The product is likely to be homogenized, if necessary, in the container by stirring caused by the rotation of the aforementioned surface.

The device may advantageously be used for packaging a product of creamy, pasty or gelled consistency, such as, for example, mascara.

The invention may allow dispensing the product on the applicator even when the device has a shape rather in width than in length. The invention can thus renew the aesthetics of the devices used for the packaging and application of mascara, for example. The invention may for example reduce the size of the device and make it more easily transportable.

The ratio of the height of the container to the largest transverse dimension of the container may be for example between 0.1 and 10, for example being close to 1.

The product may be contained in an interior space of the container and the ratio of the height of this interior space to the largest transverse dimension of the container may be for example between 0.1 and 10.

The invention makes it possible, if desired, to make the device so that it can be fixed on a mirror, which is not the case of conventional packaging and mascara application devices.

The first and the second part may for example cooperate by snapping, so as to allow their relative rotation, while preventing relative axial movement.

The first and the second part can be assembled so as to have a tight junction. For this purpose, one of the first and second parts may for example comprise a seal or a sealing lip cooperating with the other of said parts.

The first part can define an interior space containing the product. Alternatively, the first and second portions may define the interior space containing the product. The first and second parts may in particular delimit laterally such a space.

The applicator may be in the center of the container. The surface may in particular turn around the applicator, when it is arranged to be recharged product being introduced into the container.

The surface whose rotation moves product towards the center of the container may be non-planar and oriented to promote flow towards the center of the container or to any other region where the applicator is located.

Where appropriate, this surface may also be inclined upwardly or downwardly to also create a product flow up or down the container.

The second part can define, with the first part, at least two chambers inside the container, and a rotation of the second part relative to the first can cause a variation of the volume of one of the chambers and an inverse variation of the volume of the other room. In such an embodiment, the applicator may for example be substantially disposed in the path of the product flowing from one of the chambers to the other chamber.

The first and the second part can still define a variable volume chamber and the rotation of the second part can cause a decrease in the volume of this chamber and the product flow to the applicator.

The product flow can be carried out for example in a direction parallel to the axis of rotation of the second part, and in particular towards the applicator, in particular in the case where the applicator is not housed inside. of the container.

As a variant, the product outlet may alternatively be carried out in another direction, for example not parallel to the axis of rotation, in particular perpendicular to it.

The first part may comprise a bottom wall comprising a first relief and the second portion a second relief cooperating with the first relief so as to pivotally guide the second portion relative to the first. The first relief is for example a recess and the second relief a lug engaged in this recess, or vice versa.

The second part may include a blade. The term "pale" should be understood in a broad sense. The blade can be made monolithically with the second part. In a variant, the blade may comprise at least one portion attached to the second portion. This portion may be made of a material different from that in which the remainder of the second part is made, for example in a more rigid or more flexible material, depending on the desired result. When the blade is attached, it is for example made with a portion for mounting fixed on the rest of the second part by snapping or friction. The portion for mounting is for example tubular and inserted by force in a neck of the second part.

The blade can be traversed by at least one opening, or even a plurality of openings, so as for example to reduce the force required to rotate the second part relative to the first part and, where appropriate, stir the product.

The second part may include an outer skirt rotatable by the user.

The second part has a neck, which can be threaded externally, so as to allow the attachment of a threaded closure cap internally.

The aforementioned surface may extend to a wall of the first portion radially outwardly defining the interior space containing the product. This may for example allow a radially outer edge of the second part to scrape the aforementioned wall and improve the emptying. The surface in question may extend at least partially parallel to the axis of rotation of the second part. Said surface may also extend at least partially along a radial plane containing the axis of rotation of the second part. Said surface may extend along at least two radii, said surface being continuous. Said surface may be secant or not to the axis of rotation. Said surface may in particular have a certain warping, and have for example a shape adapted to improve the flow of the product over the entire height of the applicator. Said surface may in particular be configured to raise the product which tends to accumulate at the bottom of the container. Said surface can thus be arranged to lift the product during its rotation and may have a portion inclined downwards and in its direction of travel.

Said surface may still have a lower edge which substantially matches the shape of a bottom wall of the container, so as to scrape the product deposited on this bottom wall. Said surface may comprise a radially inner edge which is for example curved downwards and inwards, in order to conform substantially to the shape of an applicator housed in the interior space. Said surface may have a radially outer edge which substantially matches the shape of a side wall of the container. Said surface may have a radially inner edge that substantially matches the profile of the applicator.

The device may comprise a gripping member having a longitudinal axis substantially perpendicular to the axis of rotation of the second portion. This gripping member may, where appropriate, be confused with that of the applicator.

The first part may define at least one counter-surface opposite which the above surface may come at least partially opposite, at the end of the rotation of the second part.

The counter surface or surfaces may extend substantially radially toward the center of the container. The counter surface or surfaces may be defined for example each by a partition projecting into the interior of the container containing the product.

The first part may include an outer covering part.

The second part can be made monolithically in a plastic material. Alternatively, the second part may comprise several constituent elements made separately and then assembled. In the latter case, the second portion may for example comprise an outer portion and an inner portion secured to the outer portion, the inner portion being rotatable relative to the first portion without moving axially. The inner part may for example comprise an annular sealing lip applying to the first part.

The first and second parts can be made of different materials, which can reduce the friction between the two parts and facilitate the rotation of one part relative to the other.

A blade and / or a counter surface may extend at least partially along an axis inclined relative to the axis of rotation, so as to push the product upwards or downwards of the container. In the latter case, the product can then be passed through a chimney upward or maintained at an inlet of a plunger tube communicating with a dispensing means.

The device may comprise a wiper member of the applicator.

The wiper member may be made by molding with the first and / or second part or be attached to one of them, in particular to the second part. The wiper member may in particular be made of a material different from the first and second parts

In the case of a second portion having an outer portion and an inner portion, one of the outer portion and the inner portion may carry the wiper member of the applicator. The wiper member may for example be made monolithically with the inner part.

The wiper member may be made of an injected plastic material or a foam, and the wiper member may, where appropriate, be flocked.

One of the first and second part may include a perforated chimney, which may be arranged in the center of the container or elsewhere. The applicator can be received in this chimney.

The applicator may for example extend inside the container when the closure cap is in place thereon.

The applicator may comprise a rod extending substantially parallel to the axis of rotation of the second part. Alternatively, the applicator may comprise a rod extending substantially perpendicular to the axis of rotation of the second part, or otherwise oriented. The stem can still be curved.

If necessary, the rod may have a constriction which is positioned to the right of the wiper member in the storage position, which avoids constraining the wiper member.

The applicator may be housed inside the container in a space around which the aforementioned surface rotates.

The applicator may comprise a brush, in particular a brush configured to apply the product to the keratinous fibers, for example the eyelashes and / or the eyebrows.

When the applicator comprises a rod and an applicator element, the latter may have in cross-section a maximum dimension, for example less than, equal to or greater than the diameter of the rod, depending on the nature of the applicator element.

In an alternative embodiment, the applicator does not extend into an interior space of the container filled with product. The device may comprise for example a permeable wall between the applicator and an interior space of the container containing the product.

The applicator may also be different from a brush and comprise for example an elastomeric tip or other material, felt or foam, and flocking if necessary. The applicator may include one or more cavities for loading product. The applicator may also include a ball, like a roll-on. The applicator may comprise a grid at least partially flocked, especially when the applicator is outside the container.

The applicator can be integral with the second part at least at the time of use. The second portion may include an inner conduit arranged to supply the applicator product.

The device may include a closure cap. In this case, the device may comprise a locking system in rotation of the closure cap relative to one of the first and second parts. This can make it possible to use the closure cap to rotate one of the parts relative to the other.

The product may be chosen for example from: mascara, eye shadow, lipstick, lip gloss, eyeliner, self-tanner, care product, especially lip care, anti-acne product, anti-stain, concealer, after-sun product, hair product, dermatological product, eye contour product, foundation, deodorant, this list not being limiting.

The product can be solid or semi-solid at room temperature (20 ° C).

The product may contain, for example, at least two immiscible phases, and may then be homogenized by rotating the first part relative to the second part.

The second part may have at least two blades, which can reduce the angular travel of one of the parts relative to each other.

In exemplary embodiments, the applicator may be eccentric with respect to an axis of rotation of the second portion relative to the first. The applicator is for example rotated relative to the product when one of the parts rotates relative to the other part.

The load of the applicator can be controlled, if necessary, by acting on the amplitude of the rotation of one of the parts relative to the other part.

Although not covered by the claims, the Figures 1 to 23 , 31 to 61 , and 68 to 79 are useful for the understanding of the invention by those skilled in the art.

Representatives Figures 1 to 4 a device 1 for packaging and application not included in the invention.

This device 1 comprises a container having a first portion 10 and a second portion 20 rotatable relative to the first around a geometric axis of rotation X, coinciding with the longitudinal axis of the device 1 in the example.

The device 1 further comprises an applicator 2, the latter comprising an applicator element 3 constituted, in the example illustrated, by a brush.

The applicator element 3 is connected by a rod 4 to a gripping member 5, which also constitutes a cap for closing the container.

In the example shown, the rod 4 extends coaxially with the axis of rotation X but it could be otherwise.

The rod 4 may be made for example at least partially of plastic material and comprise at least one material such as PA, PE, PP, PS, ABS, SAN, POM or PET, this list not being limiting.

The first part 10 comprises, in the example considered, a pot 11, which can for example be engaged in an outer trim piece 12. This can extend only over a portion of the height of the pot 11 .

The covering piece 12 can be retained on the pot 11 for example by friction, gluing, welding or snapping, being for example made of a metal while the pot 11 is in a thermoplastic material.

The covering piece 12 can be made if necessary in an elastomeric material, for example a thermoplastic elastomer, and have on its surface asperities facilitating its gripping by the user.

In the example considered, the pot 11 comprises in the upper part a relief 13 and an annular sealing lip 14.

Pot 11 defines, as can be seen at figure 4 , an interior space 15 in which a product P is contained. The interior space 15 may especially correspond to the space occupied by the product before the first use. The level of the product is then maximum in the container and reaches a height h _i , measured from the outer inner surface of the container.

The pot 11 which can be made in at least one plastic material, for example PE, PP, PA, POM, PS, ABS, SAN or PET, this list not being limiting, comprises a partition 16 extending radially towards the center in the interior space 15, near the application element 3, substantially matching the shape of the latter.

The second part 20 comprises an outer skirt 21 arranged to snap on the relief 13 and made monolithically in the example under consideration with a threaded neck 22, which allows the fixing of the closure cap 5.

The relief 13 is made for example in the form of an annular bead, continuous or discontinuous, in order to axially immobilize the first portion 10 relative to the second, while allowing a relative rotation between the two.

The second portion 20 comprises a blade 23, made monolithically with the outer skirt 21 and the neck 22, in the example considered. In the variant embodiment illustrated in figure 7 , the blade 23 is attached to the rest of the second portion 20, which can make it easier to achieve the blade 23 in a different material, if desired.

Preferably, the blade 23 has a shape adapted on the one hand to the application element 3 and on the other hand to the shape of the pot 11.

In the example of the figure 3 , the blade 23 has a radially outer edge 23a whose profile allows it to come close to the radially inner surface 42 of the pot 11, so as to scrape the product.

The radially inner edge 23b of the blade 23 has a lower part curved downwards and inwards, so as to conform substantially to the shape of the application element 3.

The lower edge 23c of the blade 23 substantially matches the shape of the bottom wall 44 of the container, so as to scrape the product that is present thereon.

The second part 20 may be made of at least one plastic material, for example PE, PP, PA, POM, PS, ABS, SAN or PET, this list not being limiting.

It may be advantageous to use different materials to make the first and second parts to reduce friction between them.

When the second part 20 is in place on the first part 10, as can be seen on the figure 3 , the annular sealing lip 14 is applied to the radially inner surface 25 of the outer skirt 21 to seal the assembly. Other sealing means could be used.

The device 1 may comprise, as seen on the figure 3 , a wiper member 30 which can be inserted into the neck 22 to dewater the applicator element 3 at its outlet from the container.

The wiper member 30 may be of any type and for example comprise a flexible lip 31 defining at its lower end a circular orifice 32, of diameter substantially equal to that of the rod 4. Alternatively, the orifice 32 may present a different diameter and / or a non-circular shape.

The wiper member 30 can be made of a plastic material, for example PE, PP, POM, PET, nitrile, silicone, EPDM, SIS or SEBS, a thermoplastic polyester elastomer such as for example that known under the trademark Hytrel. ^® , a thermoplastic elastomer such as for example that known under the name Santoprene ^® , this list is not limiting.

The wiper member 30 may still not be attached to the neck but molded or overmolded thereon.

As can be seen in particular on Figures 4 to 6 , the blade 23 and the partition 16 define, within the space 15, two chambers 15a and 15b which communicate with each other by a central region 15c in which the application element 3 is located when the applicator 2 is in place on the container.

Each main face of the blade 23 defines a rotary surface 40, one of which exerts a thrust on the product in the direction of rotation of the second part 20.

The partition 16 defines counter-surfaces 46. At the end of the rotation of the second portion 20 relative to the first portion 10, one of the rotary surfaces 40 is substantially superimposed on one of the counter surfaces 46 .

When the user rotates the second portion relative to the first portion in either direction, movement of the blade 23 within the gap causes a decrease in the volume of one portion. rooms 15a or 15b and a increasing the volume of the other chamber, which causes a product flow from one chamber to another in the central region 15c and the application element 3 can be loaded product.

In the example of the figure 5 it is the volume of the chamber 15a which decreases while that of the chamber 15b increases and the product flows from the chamber 15a to the chamber 15b, whereas it is the opposite in the example of the figure 6 .

When the second part 20 is rotated relative to the first part 10, the user holding for example one hand the dressing part 12 and rotating the other hand the outer skirt 21, the movement of the blade 23 in the interior space 15 causes a certain stirring of the product P, which can contribute to homogenize it.

In the illustrated example, the ratio h _e / d of the height h _e of the container formed by the first and second parts assembled to the largest transverse dimension d of the container may be between 0.1 and 10, for example 0, 1 and 2, and may especially have d > h _e / 2, which gives the device a relatively stocky silhouette, far from the highly elongated conventional appearance of the known mascara packaging and application devices.

The ratio h _i / d of the height h _i of the internal space 15 of the container to the largest transverse dimension d of the container may be between 0.1 and 10 for example, and it may in particular be d h _i .

Rod 4 of the applicator can be made with a retreint 4a, as illustrated in FIG. figure 8 . This retreint 4a can be positioned to the right of the opening 32 of the wiper member, the orifice 32 may have a diameter substantially equal to that of the rod 4 elsewhere at the retreint 4a. The presence of the retreint 4a reduces the stresses exerted by the rod 4 on the wiper member when the applicator is in place on the container. Where appropriate, as illustrated in figure 9 the application element 3 may extend along a longitudinal axis Z which forms a non-zero angle α with the longitudinal axis Y of the applicator.

In the exemplary embodiment of the figure 1 , the interior space containing the product is delimited laterally only by the pot 11.

In the variant illustrated in Figures 10 and 11 , the interior space containing the product is delimited laterally in the lower part by the pot 11 and in the upper part by the outer skirt 21 of the second part 20.

The rod 4 of the applicator can be telescopic as illustrated on the Figures 12 and 13 .

The rod 4 may comprise a first portion, for example lower 4b, engaged inside a second portion, for example upper 4c, and slidable therein parallel to the longitudinal axis Y of the 'applicator. The lower portion 4b may be made with a raised end to limit its travel displacement in the other portion 4c.

When the applicator 2 is in place in the container, the rod 4 is in its retracted position shown in FIG. figure 12 .

When the user wants to extract the application element 3 from the container, the application element 3 can bear against the wiper member 30, which makes it possible to deploy the rod 4 and leads it to take the configuration of the figure 13 .

Once the rod 4 has been deployed, the user can make the applicator element 3 pass through the wiper member 30.

When returning the applicator element 3 into the container, the rod 4 can first begin to retract and then the applicator element 3 to cross the wiper member.

The use of a telescopic rod can of course be associated with other containers than that shown in FIG. figure 1 .

Where appropriate, as illustrated in Figures 14 to 16 openings 45 may be made in the blade 23 so as to allow the product to pass through during its movement.

The blade 23 may comprise multiple openings 45, for example circular as shown in FIG. figure 14 , or in the form of horizontal slits as shown in figure 15 , or even a single opening 45, which may for example be in the form of a vertical slot, as illustrated in FIG. figure 16 .

The section provided for the passage of the product through the aperture (s) 45 is preferably small enough that the required amount of product flows through the central region 15c as the blade 23 is moved.

If necessary, the blade 23 may be left and have for example a lower portion curved downwards and forwards, with regard to the direction of movement of the blade in the product.

The blade 23 may comprise for example a portion 23e curved about an axis W perpendicular to the axis of rotation X, as shown in FIG. figure 14 , so as to lift the product during its movement and thus remedy the accumulation of the product at the bottom of the container under the effect of gravity.

Rather than curving the blade, it can still achieve it with a greater thickness in the lower part so that the surface 40 which is applied to the product tends to lift it.

A left blade can of course be made without the openings 45.

We illustrated on the figure 17 an alternative embodiment in which the application element 3 comprises a flocked tip.

We also showed on the figure 17 the possibility of making the first part 10 in a monolithic manner by molding plastic material, without the outer covering part 12.

We see on the figure 17 that it can realize the blade 23 with a different shape, in particular with a bent shape in the lower part, the blade 23 extending for example under the application element 3 substantially up to the axis X.

The partition 16 may also have, in the lower part, a bent inwardly and extend substantially to the X axis.

The first and second parts can be arranged in many other ways.

For example, there is shown in the figure 18 an alternative embodiment in which the bottom wall 44 is extended downwards at its periphery by a rib 50 defining a housing 51 for example to accommodate a mirror or a product sample, not shown.

In this example, the outer skirt 21 of the second part is provided with at least one relief, for example an annular bead 52, configured to engage in a corresponding groove 54 made at the base of the pot 11.

We also see on the figure 18 that the blade 23 can be made with a first relief, for example a lug 56, cooperating with a second relief, for example a recess 57, made in the first part 10. This recess 57 is for example symmetrical of revolution around the X axis, so as to provide some guidance of the lower portion of the blade 23 during the rotation of the second portion 20.

In the variant illustrated in figure 19 , the lug 56 is made integral with the bottom wall 44 and the recess 57 in one piece with the second portion.

Where appropriate, at least one of the first and second parts may be provided with a chimney within which the applicator element 3 is positioned when the applicator 2 is in place on the receptacle.

In the example of the figure 20 , the second part 20 has been made with a chimney 60 which engages in the central region 15c of the internal space 15 of the pot 11, this chimney 60 being traversed by a plurality of openings 61 allowing the circulating product of the one of the chambers 15a or 15b to the opposite chamber to cross it and to load the applicator element 3 present inside thereof.

The bottom wall 44 of the pot 11 may be made, if necessary, with a first relief 63, such as a lug, arranged to cooperate with a second relief 65, such as a recess, made in the bottom wall of the chimney 60.

In the example of the figure 21 it is the first part 10 which is made with a chimney 70 comprising, like the chimney 60 previously described, openings 71 being for example in the form of slots elongated along the axis X.

The applicator element 3 can be housed in this chimney 70 when the applicator 2 is in place on the receptacle.

The second part 20 can be made in a monolithic manner, by molding plastic material or, alternatively, by assembling at least two parts made separately and then assembled.

In the example of the figure 22 , the second part 20 has an outer part 75 cooperating with the first part 10 to ensure the axial retention of the second part 20 with a possibility of rotation about the X axis, and an inner part 76 rotating with the outer part 75.

The outer part 75 can be assembled in various ways with the inner part 76. The outer part 75 can for example comprise the neck 22 and the part inside 76 an insert 78 engaged in the neck 22, this insert 78 being for example made in one piece with a wiper member 79. The inner part 76 may also comprise, for example, a plate 80 supporting the blade 23 and provided at its periphery with an annular sealing lip 82 applied to the radially inner surface of the pot 11.

The second part 20 of the variant embodiment of the figure 23 also includes an outer portion 75 and an inner portion 76. In this example, it is the inner portion 76 that cooperates with the first portion 10 to axially retain the second portion 20 on the first portion 10. The inner portion 76 comprises, for example an outer skirt 83 having an internal groove 84 in which is engaged an outer bead 85 of the pot 11 to ensure the axial retention of the second portion 20 with a possibility of rotation about the axis X. The inner portion 76 also comprises a lip sealing ring 82 applied to the radially inner surface of the pot 11. The outer portion 75 is assembled with the inner portion 76 by friction for example. The wiper member 30 is attached to the neck 22, which is formed with the outer portion 75, and sealingly engages a chimney 86 made with the outer portion 75.

In the embodiments described above, the first part 10 comprises a partition 16 defining at least one counter-surface 46. In the device according to the invention shown in FIGS. Figures 24 and 25 the first part 10 does not have such a partition. The second portion 20 comprises a blade 23 defining two rotary surfaces 40, at least one of which has a curved shape so as to deflect the product towards the center when the blade 23 rotates in a suitable direction, for example the opposite direction of the needles. a watch for the example shown in figure 25 .

In the example of Figures 24 and 25 , the inner space 15 has only one chamber. The product P is moved inside this chamber during the relative rotation of the second part 20.

On the figure 24 it has also been illustrated that the applicator may be made otherwise than with a brush, for example with a comb made by plastic injection.

In the examples which have just been described, the applicator is extracted from the container in a direction which is substantially parallel to the axis of rotation X.

In the embodiments which have just been described with reference to the drawing, the applicator 2 comprises an application element 3 intended to be extracted from the device during use, and mounted at the end of the rod 4. In these examples, the applicator element 3 is housed, when the closure cap 5 is in place on the container, inside the container containing the product.

The application element 3 can be permanently fixed to the device and / or may not be fully housed in the space containing the product in the absence of use.

For example, the following Figures 31 and 32 a device 100 having a first portion 110 and a second portion 120 rotatable relative to the first portion 110 about a geometric axis of rotation X coincides with the longitudinal axis of the device in the example.

The device 100 further comprises an applicator 102, the latter comprising in the example in question an application element 103 comprising for example a foam, this application element 103 being carried by an inner skirt 150 of a closure cap 105 also constituting a gripping member.

The cap 105 may comprise an annular sealing lip 151 applied on the inner wall of a neck 122, the latter being for example externally threaded and made in one piece with the second part 120.

The first part 110 comprises in the example considered a pot 111 defining an interior space 115, as can be seen in FIG. figure 32 in which the product is contained.

The pot 111 comprises a partition 116 extending radially towards the center of the interior space 115, to the vicinity of the X axis, and in the upper part an annular sealing lip 114, provided externally with a relief 113 for the attachment of the second part 120. The relief 113 is for example an annular bead.

The second portion 120 has an outer skirt 121, arranged to snap on the relief 113, and made monolithically in the example with the collar 122.

A blade 123 is also made monolithically with the outer skirt 121 and the neck 122 in the example in question.

The radially inner edge 123b of this blade 123 is located in a central region 115c of the interior space 115, preferably at a small distance from the radially inner edge of the partition 116.

The bottom wall 144 of the pot 111 comprises, in the example in question, a first relief constituted for example by a recess 124, arranged to cooperate with a second relief consisting for example of a lug 125 made on the lower edge 123c of the blade 123, so as to guide the latter in rotation.

The radially outer edge 123a of the blade 123 extends almost as far as the inner wall 142 of the pot 111, so as to scrape the product deposited on this wall 142. The device of Figures 31 and 32 works as follows.

The blade 123 defines two opposed surfaces, rotating, and the partition 116 defines two counter surfaces 146 associated.

The partition 116 defines with the blade 123 two chambers 115a and 115b. When the second portion 120 is rotated relative to the first portion 110, the blade 123 moves and its movement is accompanied by a decrease in the volume of one of the chambers 115a or 115b and a product outlet to the application element 103.

The figure 34 illustrates the possibility of interposing a permeable wall 180 comprising for example a screen or a grid and defining at least one opening 181, better a plurality of openings 181, between the application element 103 and the interior space 115.

In the example of the figure 33 the applicator 102 is secured not to the closure cap 105 but to the second portion 120.

In the illustrated example, the application element 103 comprises a foam having, for example, a recess 190, defining an internal surface 191 arranged to receive the product P during the rotation of the second part 120.

The closure cap 105 may include an annular sealing lip 151 cooperating with a wall 192 of the second portion 120 extending around the applicator element 103.

We also see on the figure 33 that the cap 105 may have various configurations and for example an upper wall whose shape is adapted to that of the application element 103.

In the example of the figure 33 , the blade 123 is made with a relief 125, constituted for example by a lug, cooperating with a second relief 124, constituted for example by a recess, the bottom wall 144 of the pot 111.

The latter can be extended downwards at its periphery by a skirt 150 defining a housing 151 allowing for example to house a mirror or a product sample. In the example shown, the bottom wall 144 has in the housing 151 a boss for forming the recess 124.

Like what has been described with regard to the figure 31 , the product P is housed in an interior space 115 in two chambers 115a and 115b of the pot 111, delimited by the blade 123 and the partition 116.

The product P is driven to the applicator element when the blade 123 is rotated in either direction by the user. A conduit 193 may be made in one piece with the second portion 120 for channeling the product P from the pot 111 to the recess 190. The product P comes into contact with the inner surface 191 of the applicator element 103 allows to feed it.

In the example of the figure 35 , the application element 103 is intended to apply product on the lips and has an upper face 103a which is inclined relative to the axis of rotation X. This upper face 103a can be supplied with product by a channel 103b passing through the Application member 103. This channel 103b can be closed, when the closure cap 105 is in place, by a pin 105a thereof.

The outer shape of the closure cap, the first part 10 or the second part 20 can be modified.

For example, the following Figures 37 to 49 some examples among others of possible shapes for the cap 5, the first part 10 and the second part 20.

The possible shapes may vary along the longitudinal axis Y or along any transverse axis, for example.

The forms that are illustrated on the Figures 37 to 49 are also valid for the examples of Figures 31 to 36 , replacing the reference signs 5, 10 and 20 by 105, 110 and 120 respectively.

In the example of the figure 37 , the outer skirt of the second portion 20 radially protrudes with respect to the first portion 10.

In the example of the figure 38 it is the first part 10 which forms radially projecting with respect to the second part 20.

In the example of the figure 39 , the general shape of the device is significantly elongated, in the manner of a pen.

The figure 40 illustrates the possibility of making the closure cap 5 with a concave shape to the outside, so as to facilitate its grip.

On the figure 41 , the closure cap 5 has a truncated ogival shape and the first portion 10 has a frustoconical shape, of decreasing downward cross section.

On the figure 42 the first 10 and second 20 parts have rounded edges.

On the figure 43 , the height of the closure cap 5 is greater than that of the first 10 and second 20 assembled parts.

The first portion 10 may comprise a double wall, with an outer wall 99 and an inner wall 11 having for example different lower cross sections.

The outer wall 99 may for example have a substantially square or rectangular cross-section as illustrated in FIG. figure 44 , or another form, for example a lenticular shape, as illustrated on the figure 45 .

The second portion 20 may also include a double wall, with an outer wall 410, and the contours of the walls 99 and 410 may coincide only in certain angular positions of the first portion relative to the second portion, as shown in FIG. figure 77 .

The second part 20 may comprise an outer covering piece 95, for example an elastomer, as illustrated in FIGS. Figures 46 and 47 .

On the figure 46 , the outer trim piece 95 is in the form of a sleeve cooperating for example by friction with the outer skirt 21 not visible. This sleeve is for example in axial section concave outwards over its entire circumference.

On the figure 47 the outer part 95 is also in the form of a sleeve, which may have a generally convex shape to the outside.

Can be filmed on the outer skirt 21 of the second portion 20 reliefs, for example fins 96, as illustrated on the figure 48 .

We can still dress one and / or the other of the first portion 10 or second portion 20 with a double wall 97, as illustrated on the figure 49 , creating an impression of volume.

The cross section of the first and / or second part may have various shapes in at least one point along the Y axis, for example generally circular as illustrated on the figure 50 , substantially square, with possibly rounded corners, as illustrated on the figure 51 , substantially triangular as illustrated on the figure 52 , for example with rounded corners, or substantially oval, as illustrated on the figure 53 .

Within the same device, the cross section of the first and / or second portion may vary along the longitudinal axis X.

For example, there is shown on the figure 54 a device whose cross section passes from an oval shape at its lower end to a circular shape at the junction between the first portion 10 and the second portion 20, to then become oval again at the top of the container, under the closure cap 5.

Such a variation in the shape of the cross section of the container with a circular junction between the first and the second part, may allow to have a container of original shape without damaging the seal and may facilitate the gripping of the first and second parts to rotate them relative to each other.

On the figure 55 the first portion 10 has a generally circular cross section and the cross section at the lower end of the second portion 20 evolves to a substantially square shape at the top of the container, under the cap 5.

Whatever the shape of the container, the closure cap 5 may comprise a locking system for maintaining it substantially stationary relative to one of the first and second parts. With the locking system, the cap 5 does not unscrew when the first portion 10 rotates relative to the second portion 20. This may facilitate the user's drive of one of the rotating parts.

In the embodiment illustrated in Figures 56 and 57 , the locking system comprises a push-button 220 on the closure cap or alternatively (not shown) on one of the first and second parts, making it possible to rotate the closure cap or not, and one of the first and second parts.

When the user presses the push button 220 and rotates the second portion 20 relative to the first portion 10, the closure cap 5 remains integral with one of the parts and does not detach.

We have shown on Figures 58 and 59 another embodiment of a device according to the invention, wherein the container has large longitudinal outer ribs.

The second portion 20 has an outer portion 75 having an externally threaded collar 22 on which the closure cap 5 can be screwed.

The neck 22 is connected below a shoulder 225.

The wiper member 30 rests on the upper edge of the neck and has an annular retaining lip 230 bearing under the shoulder 225.

The wiper member 30 has an inwardly extending wiper lip 231 which, in the illustrated embodiment, is applied in the closed position of the device against the rod 4 of the applicator 2.

The outer portion 75 has a generally cylindrical portion 232 extending downwardly under the shoulder 225 in the extension of the closure cap 5.

This cylindrical portion 232 may be grooved internally so as to facilitate the holding in force of an inner portion 76 immobilized in the outer portion 75, for example by clamping in the cylindrical portion 232.

The inner portion 76 carries the blade 23 in the example.

The generally cylindrical portion 232 is connected below a hemispherical portion 311 having a cylindrical surface of revolution 310 against which a sealing lip 14 of the first portion 10 can be applied.

The portion 311 may comprise, as illustrated, an inner annular groove 312 on which the first portion 10 can snap.

The first part 10 is made in one piece in the illustrated example, for example by molding plastic material.

The application element 3 is for example a mascara brush but can be of any other type.

The application element 3 may for example be a tip having a larger transverse dimension smaller than the diameter of the rod, as shown in FIG. figure 60 .

The wiper member 30 may comprise, as illustrated in FIG. figure 61 , a wiper lip made in one piece with the neck 22 and extending inside thereof to perform its spin function.

Any suitable device described above or in the following may be accompanied, as illustrated in FIG. figure 71 , in a set 300, a tube 250 or other container comprising at least one additional compound, for example a solvent, to be added for example at the moment of use to the product contained in the device.

The rotation of the first portion 10 relative to the second portion 20 then allows the product to be mixed with the compound thus introduced and to homogenize the mixture.

For example, an oil can be added to a hot-cast lipstick when filling the device. This oil can give, for example, more shine to lipstick.

It is not beyond the scope of the present invention when the blade 23 and / or the partition 16 has (s) a different shape. In particular, the thickness of the blade 23 and / or the partition 16 may be different. For example, the blade 23 and / or the partition 16 may have in cross section a generally triangular, rectangular or other shape.

It is not beyond the scope of the present invention when the application element is in a different form, for example brush, comb or other.

For example, the following Figures 72 to 76 other examples of application elements.

For example, the application element may be hollow, which is the case with the examples of Figures 72 to 73 .

On the figure 72 , there is shown a comb for eyelashes or eyebrows which comprises for example two sets of teeth 400, 401 interlocking and connecting at their base to a frame 402.

The application element 3 of the figure 72 is for example made according to the patent application US 2002/0005209 whose contents are incorporated herein by reference.

On the figure 73 , the application element 3 comprises a central cavity 403. The latter can be loaded in product when the first and second parts of the container are rotated relative to each other.

On the Figures 74 and 75 , there is shown an application element 3 which has a generally flattened shape, of thickness for example less than the diameter of the rod 4, so that the product can be present on each of the main faces of the element of application 3 after removal thereof and through a wiper member.

The application element 3 represented at figure 76 has no through cavity but at least one cavity 406 on one of its main faces, in this case two cavities 406 opposite. The applicator element 3 comprises an enlarged distal end 407, the largest transverse dimension of which corresponds for example substantially to the diameter of the rod 4. The product can accumulate in each of the cavities 406, even in the event of the passage through the application member 3 of a wiper member of diameter substantially adapted to that of the rod 4.

One of the parts 10 and 20 may comprise several blades 23, for example two diametrically opposed blades 23, as illustrated in FIG. figure 78 and the other part may comprise several partitions 16, for example two partitions 16 diametrically opposed. The shape of the blades and partitions can be any, with for example one or more openings, and be flat or not.

We have shown figure 79 a device which differs from that shown in figure 59 in particular by the fact that it comprises an application element 3 composed of a tip intended for application to the lips or the skin, which can be coated with a flocking 413.

A space 414 is formed around the application element 3 in such a way that after rotation of one of the parts relative to the other, a film of product remains around the application element 3. can be relatively thick.

The neck may include a wiper lip 415. The latter may be made in one piece with the blade 23 or alternatively be formed of an insert.

Spin lip 415 can still be removed. Whatever the device, and especially in the case of the device in question, it may comprise several phases of a product to be mixed before use.

The characteristics of the various examples of implementation of the invention can be combined with each other within non-illustrated variants.

All types of materials may be used to produce the different parts of the device, in particular the first and second parts and the cap, in particular glass, metal, wood, plastics, alone or as a mixture, so as to obtain the conservation of the necessary product.

The products contained in the device can be adapted to care, makeup, dermatology or hairdressing, among others.

The invention makes it possible to mix immiscible or traditionally unused products for such applications because bi or triphasic.

The device allows homogenization of the mixture, by relative rotation of the first and second parts. Thus, new products are usable, for example for makeup, bringing new makeup effects, or better holding or other new or improved properties.

A pasty or even solid product may for example be cast hot or cold in the device during its initial filling and then added with another product, as mentioned above, in particular a liquid product, for example a silicone gum, a silicone oil or polybutylene, the whole being mixed by the device to deliver a homogeneous final product.

Several unstable and / or incompatible ingredients may be introduced hot or cold into the device during its initial filling or later, which makes it possible to obtain products delivered by the device having rheologies or properties that are difficult to obtain otherwise.

The product contained in the device can be heated, for example in a microwave oven, before use, to improve the holding of the product, for example. The relative displacement of the two parts of the container can make it possible to homogenize the temperature before application.

The expression "having one" shall be understood as being synonymous with "having at least one", unless the opposite is specified.
