    [0001] The present invention relates to an applicator for applying a cosmetic, makeup or care product to the eyelashes and / or the eyebrows, for example mascara. The invention also relates to devices comprising a container, containing the product to be applied and provided with a wiper member, and the applicator. EP 1 726 234 and EP 1 169 941 are known applicators comprising branches carrying application elements and leaving between them one or more openings. The application US 2008/0245382 relates to an applicator having helical branches carrying application elements, which alternate with helical sectors bearing bristles. The applications FR 2 962 015 and FR 2 943 226 also describe applicators comprising a twisted core. The application FR 2 936 691 describes an applicator comprising a twisted core carrying application elements, present prior to twisting the core. Application FR 2 958 129 discloses an applicator comprising a drive system for passing a core, carrying molded application elements, from a rest configuration, where the core is non-twisted, to a configuration where she is twisted. This applicator is relatively complex to make, and it is rather imposing because of the presence of the drive system. There is a need to further improve the applicators for the application of a product, especially mascara, on the eyelashes and / or the eyebrows, in order to improve their performance, and more particularly to promote the creation on the body of the eye. application of more product-laden areas, which allow easy makeup and a fast and abundant load of eyelashes and / or eyebrows, while allowing different makeup effects. There is also a need to circumvent the current limitations of the manufacturing processes of such applicators. According to one of its aspects, the subject of the invention is an applicator for applying a cosmetic, makeup or care product to the eyelashes and / or the eyebrows, comprising an applicator member comprising: a core extending along a longitudinal axis, and - at least one arch whose ends are connected to the core, carrying application elements, and extending in a twist around the longitudinal axis of the core, the distance between the arch and the longitudinal axis of the core, measured perpendicularly to the core, being variable along the core and passing through a maximum distance of the connection ends of the arch to the core. The invention makes it possible to obtain, on the applicator member, between the core and the hoop, thanks to the twist and the variable distance between the core and the hoop, at least one zone forming a reservoir , which provides after spin a surplus of product. The latter allows, from the first application, a large and satisfactory load of product eyelashes and / or eyebrows. These can then be easily separated using the application elements carried by the hoop. The invention further relates to a method of manufacturing an applicator according to the invention. This process may comprise steps in which: two molded portions are molded by at least one arch bearing application elements, and a rotation is applied to one of the portions relative to the other so that the The arch extends in a twist around a longitudinal axis of the applicator. This manufacturing process overcomes the delicate problem of demolding twisted parts. Indeed, the two portions and the bow are first molded without twisting, and the two portions are then rotated relative to each other. The hoop can thus take a rest configuration, where it is straight, not twisted, and a twisted configuration. The arch is advantageously initially contained in the same diametral plane as the axis of the two portions that connects after molding.
    [0002] Thanks to the step of twisting after molding, from the same mold, it is possible to make applicators with different configurations. The arches and have more or less difference with the soul, which allows to have applicators offering more or less definition to the application and different makeup effects. "Distance between the hoop and the longitudinal axis of the web" means the distance, measured along the longitudinal axis of the web and perpendicular thereto, between the longitudinal axis of the web soul and the face of the arch not carrying the application elements and facing the soul.
    [0003] By "longitudinal axis of the soul" is meant the line joining the set of centroids of the cross sections of the soul. The longitudinal axis may be a central axis or an axis of symmetry for the core, especially when the core has a circular cross section or generally polygonal regular shape. The longitudinal axis of the core may be rectilinear or curved and may be contained in a plane, which may be a plane of symmetry for some or all cross sections of the soul. Preferably, the longitudinal axis of the core is rectilinear. By "application element" is meant an individualizable projecting element intended to come into engagement with the eyelashes and / or the eyebrows.
    [0004] Core and hoop The twist of the hoop results from an angular offset, around the longitudinal axis of the soul, between the connection ends of the hoop to the soul. The angular offset can be between 30 ° and 360 °, better between 30 ° and 180 °. The twist of the arch then extends over less than one complete revolution around the longitudinal axis of the soul. In a variant, the angular offset around the longitudinal axis of the core between the connection ends of the bow to the core is greater than or equal to 180 °, better than or equal to 360 °. The twisting of the hoop may go clockwise or counterclockwise as one moves from the proximal end to the distal end of the applicator member. The direction of the twist may be such that the applicator is advantageously inserted into a container, containing the product to be applied, in the direction of the twist, which facilitates its insertion. The applicator is advantageously cons extracted from the container in the opposite direction in the direction of the twist, which allows it to oppose greater rigidity to the product and allows a more efficient mixing of the latter before sampling. The distance between the arch and the longitudinal axis of the core may increase, from the distal end of the connection of the arch to the core, to reach a maximum, located substantially midway between connecting ends of the arch to the core, and then decrease again to the proximal end of the connection of the arch to the core. In twisted configuration, the greatest distance between the hoop and the longitudinal axis of the core may be between 1 mm and 5 mm, better between 2 mm and 3 mm.
    [0005] The length of the hoop, in its rest configuration, is greater than the gap along the longitudinal axis of the web between the connection ends of the hoop to the core, in the twisted configuration of the hoop. implementing body. The arch is a length at rest to obtain the desired angular offset to achieve the twist and to have the desired change in the distance between the arch and the soul. The ratio between the length of the arch and the gap along the longitudinal axis of the web between the connection ends of the arch to the core, in the twisted configuration of the applicator member, can be between 1.5 and 3, better between 1.5 and 2. The largest cross section of the arch is preferably less than the smallest cross section of the core, being in particular at least 2 times lower . The arch is thus more deformable than the soul, which is more rigid. The largest cross section of the hoop can be between 0.5 mm 2 and 1.5 mm 2, better between 0.8 mm 2 and 1.2 mm 2. The largest cross section of the core may be between 2 mm 2 and 15 9 mm 2, more preferably between 3 mm 2 and 6 mm 2. The hoop may have a cross section of circular or non-circular shape, for example polygonal, in particular hexagonal or rectangular, or elliptical. The core may have a cross section, taken perpendicular to its longitudinal axis, of circular or non-circular shape, for example polygonal, in particular hexagonal or rectangular, or elliptical, or in the form of a cross with three, four or more branches. The soul may be hollow or full. The length of the core may be between 15 mm and 30 mm. The core advantageously carries a plurality of arches, in particular between two and ten arches. This makes it possible to obtain a plurality of reservoir zones and / or a large reservoir zone, providing after extraction of the applicator member a surplus of product. In this case, the arches can be images of each other by a rotation of 360 ° / n about the longitudinal axis of the soul, where n is the number of arches. The core may carry application members extending therefrom, in particular arranged along one or more longitudinal rows. The user can access the application elements of the soul through the flexion of bow or bowels that are flexible, during application.
    [0006] The application elements of the core can be used to load the eyelashes and / or the eyebrows in product through the reservoir area, and the application elements of the or the arches can separate the eyelashes and / or the eyebrows by painting them. The soul is preferably a central soul. When the core carries a plurality of arches, the longitudinal axis of the core is advantageously equidistant from the arches over its entire length, all around its longitudinal axis. When the core carries a plurality of arches, at least two arches may have proximal, respectively distal, core-connected ends that are axially offset along the longitudinal axis of the core.
    [0007] The core may comprise two portions assembled by any means, in particular by friction, latching, welding, gluing, stapling, stamping or embedding. One of the portions of the core may comprise a non-cylindrical tip of revolution intended to fit into a complementary housing formed in the other portion. The ends of the or arches are connected to these two portions respectively. The two portions of the core are advantageously assembled after the rotation of one relative to the other to create the twist of the hoop. The assembly of the two portions of the core makes it possible to form a continuous core and to keep the applicator in the desired twisted state. In order to maintain this twisted state, the relaxation of the two portions of the core relative to one another can be prevented by any means, for example by the use of portions having non-symmetrical cross sections of revolution, or by the use of at least one portion having streaks on its part intended to come into engagement with the other portion. In a variant, the core comprises a metal insert, this insert being in particular overmolded, preferably over its entire length, by a thermoplastic material in which at least a portion of the core carrying the hoop and / or the headband. The metal insert may be of circular section, being for example cylindrical, or non-circular, for example rectangular or U-shaped or L-shaped. An insert of non-circular section makes it possible to improve the anchoring of the material on the insert. In another variant, the core comprises two metal branches intended to be twisted together, which can grip bristles, in the same way as conventional mascara brushes said twisted core. In this case, the two portions, made of thermoplastic material to which the ends of the hoop are connected, are advantageously gripped by said branches after twisting. The twisted branches maintain said portions angularly offset relative to each other, to create the twists of the arches. The two metal branches may be separate or be part of a U-shaped pin. The two portions may have any form compatible with their maintenance by the twisted branches. The core, the arch or bows and the application elements of the core and / or of the arch or bows may be molded in the same material, or alternatively may be made of at least two different materials. A part of the core, the bow or hoops and the application elements of the core and / or of the bow or hoops may for example be made in a first material, and another part of the core, of the hoops and application elements of the core and / or the arch or bars can be made in a second material, for example more flexible or harder than the first. The core and / or the one or more hoops and / or the application elements of the core and / or of the hoops or hoops may be made of an elastomeric, thermoplastic or thermosetting material. Application Elements The height of the application elements of a hoop can vary, for example in a monotonous manner, as one moves along the hoop. For example, as one moves along the hoop, the height of the applicator elements may increase between the proximal end of connection of the hoop to the core and a first abscissa, and then remain substantially constant between this first abscissa and a second abscissa, and then decrease between this second abscissa and the distal end of connection of the arch to the soul.
    [0008] In a variant, the application elements of a hoop have the same height. The application members of the arch may differ from each other by at least one of their cross-sectional shape, thickness, maximum distance to the longitudinal axis of the core, orientation, color and / or material.
    [0009] Some application elements of the hoop or all the application elements may have a thickness measured at their base, that is to say at the connection point of the application elements to the hoop, between 0.5 and 2 mm, or between 0.9 and 1.2 mm. By "thickness of an application element" is meant the largest transverse dimension of the application element, in section, perpendicular to its axis of elongation. This is a diameter when the application element is generally cylindrical or conical. By "elongation axis of the applicator element" is meant an axis which passes through the centroids of the cross sections of the applicator element. The application elements of the arch can be of any shape. The application elements may have a cylindrical or tapered shape, in particular conical, frustoconical or pyramidal shape. At least one application element may be terminated by a rounded free end, in particular a hemispherical end. At least one applicator element may extend from the hoop along an axis of elongation perpendicular to the surface of the hoop, at the point of connection of the applicator element to the hoop. Preferably, all the application elements extend from the hoop along an axis of elongation perpendicular to the surface of the hoop, at the point of connection of the application elements to the hoop. The same applies to the application elements worn by the soul, if any. Each arch may comprise between 10 and 50 application elements, for example between 15 and 25 application elements.
    [0010] The core may comprise between 10 and 50 application elements, for example between 15 and 30 application elements. In the variant where the core of the applicator member comprises a twisted core brush, the application elements carried by the core are bristles caught between the turns of the core.
    [0011] The height of at least one element of application of the arch, measured from the arch, may be between 1 mm and 3 mm. The height of at least one application element of the core, measured from the core, can be between 1 mm and 3 mm. By "height of an application element" is meant the distance measured along the axis of elongation of the applicator element between its free end and its base by which it is connected to the hoop or to the soul.
    [0012] Applicator The applicator may comprise a rod carrying at one end the applicator member and being fixed at a second end to a gripping member. The core may be molded with a fixing tip to the applicator rod.
    [0013] The applicator member may be fixed on the rod by snapping, gluing, welding, crimping, stamping, stapling, forced insertion, cold or hot, for example by mounting in a housing of the rod. Alternatively, the rod can be received in a housing provided in the core. The rod and the applicator member may be molded in one piece, in the same thermoplastic material or not. The applicator member may comprise a mounting piece integrally molded with the core, which may optionally include one or more narrowed portions to improve applicator flexibility and flexibility. application. The core may extend along a longitudinal axis making at least one point of its length an angle with the longitudinal axis of the rod to which the core is attached. The applicator member may be bent at its connection to the rod. The rod may comprise a first portion, rigid, extended distally by a second portion, more flexible, for example elastomer, carrying the applicator member. A larger transverse dimension of the core may be smaller, greater or equal to a larger transverse dimension of the shank. The largest transverse dimension of the core may be between 2 mm and 3 mm. The apparent length of the applicator member may be between 15 mm and 30 mm. Application Device The invention further relates to a device for packaging and applying a cosmetic, makeup or care product to the eyelashes and / or the eyebrows, comprising an applicator according to the invention and a container containing the product. The gripping member of the applicator may constitute a closing cap of the container. The container may comprise a wiper member adapted to dewater the rod and the applicator member.
    [0014] The largest transverse dimension of the envelope surface of the applicator member defined by the application elements of the hoops is advantageously greater than the diameter of the circle inscribed in the wringing orifice. The hoop deforms at the passage of the wiper member, during removal of the applicator from the container.
    [0015] The product contained in the container is preferably a mascara. Manufacturing process The two portions connected by the one or more arches can be molded, being only interconnected by the one or more arches, and then assembled after relative rotation of the portions relative to one another about the longitudinal axis of blade.
    [0016] In a variant, the two portions are molded together, then separated, in particular by cutting, and reassembled after relative rotation of the portions. In a variant, the two portions are overmolded on a metal insert, and the insert is deformed in torsion, when the two portions are rotated relative to each other.
    [0017] In a variant, the core comprises two twisted metal branches, which can grip bristles, in the same way as conventional mascara brushes called twisted core. Two portions of thermoplastic material are advantageously gripped by said branches after twisting, the ends of the hoop connecting to these portions.
    [0018] The two portions may extend along the same rectilinear longitudinal axis, or may form an angle after assembly. The characteristics stated above for the applicator apply to the device and the manufacturing process. The invention will be better understood on reading the following detailed description of nonlimiting examples of implementation thereof, and on examining the appended drawing, in which: FIG. 1 is a schematic view in elevation, with partial longitudinal section, of an exemplary packaging and application device produced in accordance with the invention; FIG. 2 represents, in perspective, the application member of FIG. FIG. 3 is a front view of the applicator member of FIG. 2; FIGS. 4A to 4C illustrate steps of manufacturing an applicator member according to the invention; FIGS. 5A and 5B illustrate steps of manufacturing an alternative embodiment of an application member according to the invention, - Figure 6 is a view similar to Figure 2 of an application member according to the invention being manufactured - Figure 7A shows, in longitudinal section, a variant of réa According to the invention, FIG. 7B shows a detail of the application member of FIG. 7A, after assembly, FIGS. 8, 9 and 11 represent embodiments of FIG. application members according to the invention, before rotation of the portions of the core on which the arches are connected, - Figure 10 is a cross-sectional view along XX of Figure 9, and - Figure 12 is an exploded view of an alternative embodiment of an applicator member according to the invention, before rotation of the portions of the core on which the arches are connected. FIG. 1 shows a device 1 for packaging and application made according to the invention, comprising an applicator 2 and an associated container 3 containing a product P to be applied to the eyelashes and / or the eyebrows, for example mascara or a care product. The container 3 comprises, in the example considered, a threaded neck 4 and the applicator 2 comprises a closure cap 5 arranged to be fixed on the neck 4 in order to close the container 3 tightly in the absence of use , the closure cap 5 also constituting a gripping member for the applicator 2. The applicator 2 comprises a rod 7 of longitudinal axis Y, which is connected at its upper end to the closure cap 5 and, at its lower end , to an applicator member 8. The latter comprises a core 10 extending along a longitudinal axis X. The container 3 also comprises a wiper member 6, for example inserted into the neck 4. This wiper member 6 , which may be arbitrary, comprises in the example in question a lip arranged to dewater the rod 7 and the applicator member 8 when the applicator 2 is removed from the container 3. The lip defines a wiping orifice 6a of diameter adapted to that of the tig e. In the example shown, the rod 7 has a circular cross section but it is not beyond the scope of the present invention when the rod 7 has a different section, the fixing of the cap 5 on the container 3 can then be performed otherwise than by screwing, if necessary. The wiper member 6 is adapted to the shape of the rod 7 and that of the applicator member 8, where appropriate. Preferably and as in the example considered, the longitudinal axis Y of the rod 7 is rectilinear and coincides with the longitudinal axis of the container 3 when the applicator 2 is in place thereon, but it does not leave the of the present invention when the rod 7 is non-rectilinear, forming for example a bend. The rod 7 may comprise, where appropriate, an annular necking on its portion which is positioned opposite the lip of the wiper member 6, so as not to mechanically stress it excessively during storage.
    [0019] Fixing the applicator member 8 on the rod 7 can be done by any means and in particular be done by force fitting, latching, gluing, welding stapling or crimping, in a corresponding housing provided at the end of the rod 7. The applicator member 8 may comprise, as shown in Figure 2, a nozzle 9 for fixing it in a corresponding housing of the rod 7, possibly in a marked manner. A shoulder may be provided between the core 10 and the fastening tip 9. The length / of the tip 9 may be between 6 mm and 9 mm. Alternatively, the rod 7 can be inserted into a housing provided in the core 10. The core 10 can also be made in one piece by molding material with the rod 7.
    [0020] Referring to Figure 2, we see that the core 10 is of elongate shape along the longitudinal axis X, which is rectilinear in the example described. As in the example, the core 10 may have a circular cross-section over most of its length. The longitudinal axis X may be central, as illustrated. Other forms in section are however possible.
    [0021] The length of the core may be between 15 mm and 30 mm. The apparent length H of the applicator member 8 can be between 15 mm and 30 mm, being equal to about 23 mm in the illustrated example.
    [0022] The rod 7 to which is attached the applicator member 8 may be at least partially, especially entirely flexible, in particular near the applicator member. As illustrated in FIG. 2, the applicator member 8 comprises a plurality of arches 13 whose ends are connected to the core 10 and which each extend in a twist around the longitudinal axis X of the core 10. The arches 13 carry application elements 18. The core 10 can bear between two and ten arches 13, for example 9 arches in the examples of Figures 1 to 3 and 6, two arches in the examples of 4A to 4C, 7A and 7B, 9 and 11, and three arches 13 in the example of Figure 8. In the variant shown in Figures 5A and 5B, the core 10 carries a single arch 13. The distance D between each arch 13 and the longitudinal axis of the core 10 is variable along this axis and passes through a maximum, for example halfway between the connection ends of the hoops to the core.
    [0023] The method of manufacturing an applicator 2 according to the invention comprises the steps according to which two portions 14 and 15 of the core 10, connected by arches 13, as shown in FIG. 4A, are molded and rotation to one of the portions relative to each other so that the arches 13 are deformed and each extend in a twist around the longitudinal axis X, as shown in Figures 4B and 6. The two portions 14 and then are assembled after this relative rotation. In the examples of FIGS. 4B, 5A or 6, the portion 15 comprises a tip 22 intended to be fixed in a complementary, non-visible housing formed in the portion 14, for example by welding or gluing. The end piece 22 and the complementary housing may be non-cylindrical of revolution, the end piece 22 being intended to fit into said complementary housing. In the example of FIGS. 7A and 7B, the portion 14 has a protruding relief 24 intended to snap into a recessed relief 25 of the portion 15 to assemble said portions by snapping.
    [0024] In the example of FIG. 8, the portion 14 is assembled by stapling at the portion 15.
    [0025] The twisting of the arches 13 results from an angular offset angle α around the longitudinal axis X of the core 10, between the connecting ends 11 and 12 of the arches 13 to the core 10. The angle may be between 30 ° and 360 °, being for example equal to 180 ° in the example of Figures 4A to 4C. In the variant shown in FIG. 5B, the angular offset a is greater than or equal to 180 °, for example greater than or equal to 360 °. The direction of the twisting of the arches 13 is, in the examples illustrated, in the clockwise direction, starting from the distal end of connection 11 towards the proximal end of connection 12. As can be seen in particular in FIG. 2, the distance D between the arches 13 and the web 10 increases, from the distal end of connection 11, to reach a maximum Dm, located, in the example in question, substantially halfway between the connection ends 11 and 12 of the arches 13 to the core 10, then decreases again to the proximal end of connection 12. In the twisted configuration of the applicator member 8, the greatest distance Dm between the hoop 13 and the the longitudinal axis X of the core 10 may be between 1 mm and 5 mm. As shown in FIG. 2, an assembly 20 of hoops 13 may have distal ends 11 and proximal ends 12 connected to the core 10 offset axially relative to those of another set 21 of hoops 13. The length La of the arch 13 in its rest configuration, shown in Figure 5A, is greater than the distance Lp between the connecting ends 11 and 12 of the arch 13 to the core 10, in the twisted configuration.
    [0026] The ratio La / Lp can be between 1.5 and 3. In the examples described, the largest cross section of each arch 13 is smaller than the smallest cross section of the core 10, being in particular at least twice lower. The largest cross section of each arch 13 may be between 0.5 mm 2 and 1.5 mm 2. The largest cross section of the core 10 may be between 2 mm 2 and 9 mm 2.
    [0027] The arches 13 have in the examples of Figures 1 to 4C and 6 a cross section, taken perpendicular to the axis of the twist, of rectangular shape. In the example of FIGS. 5A and 5B, the arch 13 has a circular cross section. The core 10 has, in the examples described, a cross section, taken perpendicularly to its longitudinal axis X, of circular shape. The invention is however not limited to a particular form of cross section of core and arch. In the examples shown, the application elements 18 of the arches 13 extend from the latter each along an axis of elongation perpendicular to the surface of the corresponding arch, at the connection point of the application element. 18 to the hoop 13. In a variant not shown, the axis of elongation of at least one application element 18 forms an angle different from 90 ° with the surface of the hoop 13 at the connection point of the hinge 13. element of application to the arch. The height of the application elements 18 of a hoop 13 may be constant over the entire length of the hoop and may be identical from one hoop to the other. In a variant not shown, the height of the application elements 18 may vary within a hoop and / or hoop to another. The height of the application elements 18 of the arches 13 is for example between 1 mm and 3 mm. The thickness ep of the application elements 18, measured at their base, visible in FIG. 6, is for example between 0.5 mm and 2 mm. The application elements 18 carried by the arches 13 may have various shapes. In the examples of FIGS. 1 to 4C, 6 and 8, the application elements 18 are of pyramidal shape. In the examples of FIGS. 5A, 5B and 9 to 11, the applicator elements 18 are of tapered shape. The invention is however not limited to a particular form of application elements 18. An arch 13 may comprise between 10 and 50 application elements 18, for example around 20 application elements. As shown in particular in FIGS. 5A and 5B, the core 10 can carry application elements 19 extending from it in several longitudinal rows 30, 31.
    [0028] In the examples shown, the application elements 19 of the core 10 extend from the latter each along an axis of elongation perpendicular to the surface of the core 10, at the connection point of the element d application 19 to the latter. In a variant not shown, the axis of elongation of the application elements 19 forms an angle different from 90 ° with the surface of the core 10 at the point of connection of the application elements to the core. In the examples considered, the height of the application elements 19 is constant over the entire length of the core, within a longitudinal row and from one row to another. In a variant not shown, the height of the application elements 19 may vary within a row and / or from one row to another. The height of the application elements 19 is for example between 1 mm and 3 mm. The application elements 19 of the core 10 may have various shapes. In the examples considered, the application elements 19 are of tapered shape. The invention is however not limited to a particular form of application elements 19 carried by the core 10. The core 10 may comprise between 10 and 50 application elements 19, for example around 15 elements of application. 'application. In the example of Figures 9 and 10, the core 10 comprises a metal insert 23, which is overmolded by a thermoplastic material in which is formed a portion 26 of the core 10 and the arches 13. The insert 23 then undergoes a twisting to angularly offset the connection ends of the arches to the portion 26 and create the twist of the arches 13. The cross section of the insert 23 is preferably non-circular, so as to improve its anchoring within the part 26 which surrounds. In the variant shown in Figure 11, the core 10 comprises two branches 27, 28 twisted with a U-shaped wire gripping bristles 19, in the same way as conventional mascara brushes said twisted core. As shown in Figure 12, two portions 14, 15 of thermoplastic material are intended to be gripped by the branches 27 and 28 after twisting. The arches 13 are connected to these portions. The branches 27, 28 maintain the portions 14, 15 angularly offset relative to each other, to create the twists of the arches 13.
    [0029] In the examples just described, the portions 14 and 15 of the core 10 extend along the same rectilinear axis. In a variant not shown, the two portions of the core 10 form a non-zero angle after assembly. Any thermoplastic material, relatively rigid or not, for example SEBS, silicone, latex, reinforced slip material, butyl, EPDM, nitrile, thermoplastic elastomer, a polyester, polyamide, polyethylene or vinyl elastomer, a polyolefin such as PE or PP, PVC, EVA, PS, SEBS, SIS, PET, POM, PU, SAM, PA, PMMA. The hardnesses of these materials can be between 50 Shore and 90 Shore. In particular, the materials known under the trade names Teflon®, Hytrel®, Cariflex®, Alixine®, Santoprene®, Pebax®, Pollobas® can be used, this list not being limiting.
