    The present invention relates to a wringer for a package for packaging and applying a cosmetic product.
    “Cosmetic products” means any product as defined in Regulation (EC) No. 1223/2009 of the European Parliament and of the Council of November 30, 2009, relating to cosmetic products. The packaging and application assembly according to the present application is more particularly intended for the application of a cosmetic product, such as a make-up or care product, to a keratin material and / or keratin fibers, and is especially intended for the application of mascara on eyelashes. The packaging and application assembly according to the present application may also relate to a fluid lip product such as a lip gloss or a varnish. The packaging assembly according to the present application II is also applicable to other fluid products such as eyeshadow, concealer, or liquid foundation.
    By "keratin materials" is preferably meant human keratin materials, especially the integuments, and more particularly keratin fibers.
    By “keratin fibers” is meant in particular the eyelashes and / or the eyebrows, and preferably the eyelashes. This term "keratin fibers", within the meaning of the present application also extends to synthetic false eyelashes.
    By mascara is meant a composition intended to be applied to the eyelashes. It may especially be an eyelash makeup composition, an eyelash makeup base (or "base coat"), a composition to be applied to a mascara (or "top coat"), or still a cosmetic treatment composition for eyelashes.
    The mascara is more particularly intended for the eyelashes of human beings, but also for false eyelashes. The application of mascara aims in particular to increase the intensity of the look, in particular through a more or less significant increase in the volume of the eyelashes.
    In general, the application of the cosmetic product consists in depositing a desired quantity of material on the targeted keratin surface so as to obtain the desired effect.
    The cosmetic product is applied using an applicator.
    Numerous cosmetic product applicators are known which are intended to allow the application of said product to keratin fibers, in particular mascara to eyelashes.
    In addition to the particular composition of the cosmetic product, the applicator plays an important role in the quality of the application of the cosmetic product and in the quantity of product deposited.
    In general, an applicator comprises an application member defining an application surface. The applicator member has a main body or core, generally elongated, said main body being able to carry application elements projecting from said core. The applicator member, in particular for the lip applicators, can be completely or partially covered with flock. The flock fibers help in the retention of the product and thus form application elements.
    Preferably, the application elements extend in a general direction substantially normal to the core (in particular radial).
    During application, the application member is loaded with cosmetic product and brought into contact with the fibers in order to allow the product to be deposited on said fibers. The applicator elements, spaced apart from each other, form cosmetic product reservoir zones. The applicator member is mounted at the end of a rod, generally made of plastic, secured to a gripping member. The applicator is generally intended to be used with a reservoir containing the cosmetic product to be applied and of which a free edge delimits an opening. The applicator member is introduced through the opening inside the reservoir where it takes care of cosmetic product before being extracted from said reservoir to proceed with the application.
    Thus, the applicator is movable between a first position, called the sampling position, in which the application member is located inside the reservoir and is able to be at least partially brought into contact with the cosmetic product contained in the reservoir, and a so-called application position in which the application member can be brought into contact with a part of the human body.
    This mode of use is conventionally designated by the term "dip-in" or "immersion" since it is necessary to immerse the applicator member in the cosmetic product reserve to load it with product before application.
    The reservoir is generally equipped with a closing member provided for removably closing the opening of said reservoir.
    Conventionally, the opening is located at one end of a neck of the reservoir, said neck having an external thread capable of cooperating with a corresponding internal thread of the closure member, typically a screw cap.
    According to a usual packaging method, the closing member also constitutes the gripping member of the applicator, the applicator member thus being disposed inside the reservoir when it is not in use.
    In order to eliminate excess cosmetic product and adjust the load on the applicator member, the opening of the reservoir is generally equipped with a wiper member called a wringer.
    A wringer has a generally tubular hollow structure capable of being traversed by the applicator member at least when the latter is extracted from the reservoir. The wiper comprises at least one wringing portion configured to come into contact with at least the applicator member during its extraction. Advantageously, the wringing portion is configured to also be able to come into contact with the rod on which the applicator member is mounted.
    The wiping portion is elastically deformable so as to allow adaptation of the wiper to variations in section between the rod and the applicator member as well as within the applicator member itself.
    Thus, the wiping portion is generally made from an elastomeric thermoplastic material (a nitrile rubber for example).
    By elastomeric thermoplastic materials, or TPE, is generally meant polymers or mixture of polymers which exhibit, at service temperature, properties similar to those of vulcanized rubber. These properties disappear at the processing temperature, making subsequent processing possible, but reappear when the material returns to the operating temperature (see ISO 18064: 2014 standard). For general information on elastomeric thermoplastic materials, reference may in particular be made to the Engineering Techniques guide, Plastics and Composites Treaty, AM 3 400 by Michel Biron published on July 10, 2000.
    The thermoplastic material used can be, for example, SEBS (Styrene-Ethylene / Butylene-Styrene), a silicone, butyl, EPDM (Ethylene Propylene Diene Monomer), a nitrile, a polyester elastomer, of polyamide, polyethylene or vinyl, but also a polyolefin such as polyethylene (PE) or polypropylene (PP).
    In addition to the wringing portion, intended to come directly into contact with the application member, a wringer may include a mounting portion intended for its assembly on the tank.
    The wiping portion has a free inner edge defining a wiping or scraping orifice of the applicator member and optionally of the rod.
    The wiping portion is generally configured so that the section of the wiping orifice at rest, that is to say in the absence of deformation caused by the passage of the applicator member and / or the applicator rod, which is less than the maximum section of the applicator member.
    Preferably, the section of the wiping orifice is substantially equal, or even slightly less, than the section of the applicator rod.
    Many wiper configurations have already been proposed with the aim of improving the wringing of the applicator member while being adapted to its shape and to that of the rod.
    It is thus advantageous to propose a wiping member which allows uniform wiping, without it being too vigorous, which would have the effect of making makeup more difficult.
    Examples of wipers are described in particular in the documents US4390298, US4617948, FR2504788 (serrated wiper), EP1561394 and EP0829211.
    A first type of wiper, the most widespread, comprises a wiping portion defined by an elastically deformable lip, essentially by bending, extending projecting from the tubular mounting portion.
    The wiping lip has a free inner edge defining the wiping or scraping orifice of the applicator member and of the rod.
    In order to be able to deform easily, the lip has a relatively reduced thickness and very small compared to the diameter of the wiping orifice, for example between 0.4 mm and 1 mm inclusive.
    When extracting and / or inserting the applicator member through the wiping orifice, the wiping lip deforms both in bending significantly in a longitudinal direction corresponding to the direction of extraction or insertion of the application member, and in a radial direction allowing it to adapt to the section of the application member at the time of passage through said lip.
    More specifically, the wiping lip is stretched both longitudinally and radially.
    Such a type of wringer is commonly called "lip wringer".
    In order to ensure optimal spinning, the elastomeric material used to make the spinning lip must not be too soft and it is known that spinning lips whose Shore hardness is too low lose their spinning efficiency, rendering thus difficult makeup. Conversely, in order not to eliminate too much product and maintain good ease of deformation, the hardness of the material must not be too high.
    Conventionally, the elastomeric material used thus has a hardness of between 20 and 70 Shore A.
    In addition, during the extraction of the applicator, the spinning lip must sometimes turn over. This results in initial resistance to extraction of the applicator which reduces the comfort of use and the ease of extraction.
    Wipers have also been proposed, the wiping portion of which is made of a block of cellular material, in particular a foam, in particular an open cell foam. Such a wringer is described in particular in document WO9731553A1.
    The foam block is split or axially hollowed out to allow the passage of the application element when the latter is removed from the container for use.
    Preferably, the foam chosen is flexible enough to allow the retraction of the applicator without the user having to exercise any particular attention or to bring the applicator member in a given orientation.
    The patent US644663 7 mentions the possibility of replacing the foam block with a block of elastomeric material. However, this document does not give any indication as to the characteristics or the nature of such a material.
    There is a need to further improve the wiping members and in particular to benefit from a wiping member capable of wringing the application member satisfactorily while improving the sensoriality of the user when removing the applicator.
    The present invention aims to achieve these objectives and proposes for this purpose a wringer for a container of cosmetic product, said wringer comprising a substantially tubular body comprising at least one wringing portion of which a free interior surface defines a wringing duct capable of being crossed by an applicator member in a wiping direction, said wiper being characterized in that the wiping portion is made of an elastomeric thermoplastic material having a hardness less than 70 Sh 00, preferably less than 45 - 50 Sh 00.
    The thermoplastic material may be a single elastomeric thermoplastic or a mixture of elastomeric thermoplastic materials, the mixture of which has the property of targeted hardness.
    Thus, by using a material having a relatively low hardness compared to the materials usually used for the production of wiping lips, it has been found that it was possible to obtain a more precise and finer wiping of the organ d 'application, the greater deformability of the spin portion allowing it to better match the contours of the application member. Spinning is generally more uniform and more homogeneous without being too vigorous.
    Preferably, the elastomeric thermoplastic material has a hardness of less than 30 Sh 00, preferably less than 20 Sh 00.
    By using a material having a very low hardness compared to usual materials, it has been found that it was possible to obtain a very precise and very fine spin of the applicator member, the very great deformability of the portion d spin allowing it to perfectly fit the contours of the applicator member.
    According to a preferred embodiment, the wiping portion has, in the absence of deformation due in particular to the passage of the applicator member, a tubular shape, preferably cylindrical, the wiping orifice having a preferably circular section .
    Preferably, the length of the wiping pipe, in the wiping direction, is greater than or equal to a diameter of the wiping pipe.
    Also preferably, the thickness of the wringing portion, in a direction perpendicular to the wringing direction and over at least the majority of the length of the wringing duct, is greater than or equal to half the diameter of the duct d 'wringing, preferably greater than the diameter of the wringing duct. The use of a block wringer, that is to say comprising a relatively thick and high wringing portion, limits the bending deformation of said wringing portion and favors a deformation in compression in a direction substantially transverse to the direction of insertion and extraction of the applicator (spin direction).
    This results in a more homogeneous spin and an absence of "hard point" felt by the user during the extraction (since there is no inversion of the lip).
    Furthermore, the use of a non-porous TPE material makes it possible to avoid the phenomenon of clogging of the foam by the cosmetic product, which, over time, can alter its properties, and also presents a risk. greater bacteriological proliferation. The use of a TPE material also limits the risks of permanent deformation of a foam as and when the applicator goes back and forth.
    Advantageously, the wiper duct has an insertion orifice and / or an extraction orifice for the application member of frustoconical shape. This helps to center the application member during its extraction / insertion. This feature also allows for a more gradual scraping at the inlet / outlet of the dewatering duct.
    According to a first alternative embodiment, the wiper comprises an attachment portion, said attachment portion preferably being made integrally with the wiping portion, in particular by molding or injection-molding, or in a different material, preferably another elastomeric thermoplastic, for example by bi-injection.
    According to a second alternative embodiment, the wiper has no attachment portion.
    Advantageously, the wiping portion comprises an external surface having an at least partially peripheral bead, preferably completely peripheral, the bead preferably having a section of rectangular profile.
    The presence of a peripheral bead makes it possible to wedge and maintain a space between the wiping portion and a possible side wall against which the wiper would be disposed, said side wall then serving as a compression stop during the passage of the member d 'application through said spin portion. The presence of a clearance with the side wall makes it possible to modify the nature of the response of the material of the wiping portion, and in particular its scraping force, during the passage of the applicator member. More specifically, in the case where the wiping portion abuts against a side wall, the wiping portion will naturally tend to work in compression since said wiping portion will be blocked against said wall when the member d 'application. On the other hand, in the case of a space provided between the wiping portion and a possible side wall (or absence of lateral stop), said wiping portion will rather tend to work in elongation. The work in elongation then makes it possible to rely essentially on the intrinsic qualities of the material of elasticity and hardness.
    Advantageously, the outer bead is located at one end, preferably a lower end, of the spin portion, taken in the spin direction.
    The directions are given relative to the orientation of the wiper as installed in the packaging and application device. Thus, the directions up and down must be understood to mean respectively, intended to be oriented towards a dispensing opening of the product and intended to be oriented toward a bottom of the reservoir situated opposite the dispensing opening.
    Advantageously, the wiping portion comprises at least one additional duct forming a vent, configured to ensure air communication between a first interior space of a tank situated on one side of the wiping portion and a second space located on an opposite side of the spin portion.
    The presence of a vent made in the wiping portion makes it possible to avoid any phenomenon of overpressure or depression during the introduction or extraction of the applicator member through said wiping portion. Indeed, the high deformability of the elastomeric material used leads to greater intimacy of the material with the application member and to increased sealing when the application member passes.
    The occurrence of an overpressure or depression can lead to a suction noise or the like which is not very attractive to the user.
    The present invention also relates to a device for packaging and applying a product, in particular a cosmetic product, comprising a body forming a reservoir intended to contain the cosmetic product to be applied and of which a free edge delimits an opening capable of allowing at least the extraction of an applicator member from inside the tank, the opening being equipped with a wringer according to the invention.
    Preferably, the opening is located at the end of a neck, the wiper preferably being arranged at least partially inside the neck, in particular by a hooking portion capable of cooperating with complementary retaining means of said hanging portion.
    Advantageously, the wringing portion is located after the neck inside the reservoir, said wringing portion preferably having an upper surface coming into contact with an internal surface of a shoulder of the neck.
    According to a preferred embodiment, the wiper has no hooking portion and is disposed in a wiper holder having at least one perforated bottom wall, the wiping portion being preferably spaced over a majority of the length of the conduit d wringing of a side wall of the wiper or of the reservoir.
    In an advantageously complementary manner, a zone for holding the wiping portion, formed in particular by the shoulder of the neck and / or the lower surface of the wiper holder, may be adapted as a function of the desired flexural deformation when passing the enforcement body.
    Indeed, in the case of a holding zone extending substantially over the entire thickness of the wringing portion, the latter will be blocked in bending in the passage of the applicator member. It is possible to reduce the length of this holding zone so as to allow a more or less significant flexural deformation.
    The present invention will be better understood in the light of the detailed description which follows with reference to the appended drawing in which: - Figure 1 is a schematic representation in longitudinal section of a first packaging and application unit equipped with a wringer according to the invention devoid of attachment portion. - Figure 2 is a schematic representation in longitudinal section of an alternative embodiment of the wiper of Figure 1. - Figure 3 is a schematic representation in longitudinal section of a second set of packaging and application equipped with 'a wringer according to the invention having a hooking portion. - Figures 4 and 5 show alternative embodiments of a wringer according to the invention. - Figures 6 and 7 are photos of a spin obtained with a block wringer made respectively in a foam of hardness 20 Sh A and in an elastomeric thermoplastic of hardness 17 Sh 00.
    Unless otherwise provided, the wringer configurations are given at rest, that is to say in the absence of deformation due to the passage of the applicator member during a movement of extraction and / or insertion.
    In addition, the directions are given relative to the orientation of the wiper as installed in the packaging and application device. Thus, the directions up and down must be understood as meaning respectively, intended to be oriented towards a dispensing opening of the product and intended to be oriented towards a bottom of the reservoir situated opposite the opening of sampling / dispensing.
    FIG. 1 shows a packaging and application unit 1 comprising a body forming a reservoir 10 intended to contain the cosmetic product P to be applied and of which a free edge 11 delimits an opening 12. More precisely, the opening 12 is located at one end of a neck 13 of the reservoir 10.
    As will be described below, for assembly purposes, the neck 13 is produced in the form of a hoop 10a attached to a main part 10b of the reservoir 10, in particular by snap-fastening, clipping or screwing.
    The reservoir 10 is equipped with a detachable closure member 14 provided for removably closing the opening 12 of said reservoir 10. In this case, the closure member 14 is in the form of a cap adapted to come engaged with the neck 13 in particular by screwing.
    According to the embodiment shown, the cap 14 is screwable and for this purpose has an internal thread 14a capable of cooperating with an external thread of the neck 13a. Obviously, other closing methods can be envisaged, for example a closing of the magnetic type. The packaging and application assembly 1 comprises an applicator 20 comprising a rod 21 having a first end linked to the closure member 14 and a second end linked to an application member 22. The closure member 14 constitutes an applicator gripping member 20. The application member 22 comprises an elongated main body projecting from a set of application elements. The application elements define between them a plurality of spaces for loading and applying the cosmetic product P.
    In this case, the applicator member 22 is a mascara applicator.
    Although illustrated by an applicator member 22 made of a molded elastomeric thermoplastic material, the present application is obviously not limited thereto and the applicator member 22 can be, in particular for mascara, an organ of application called "fibers" or "twisted core" formed by the helical winding, or twisting, of two branches of a metal wire forming a core around tufts of bristles extending radially from the metal wire. The applicator member 22 can also be a hybrid or mixed applicator member.
    In addition, the applicator member 22 is not limited to a mascara applicator and can be any applicator suitable for the cosmetic product contained in the reservoir. The applicator 20, by means of the closure member 14, is movable between a first position, called the sampling position, in which said application member 22 is located inside the reservoir 10 and is capable of being at least partially brought into contact with the cosmetic product P, and a second position, called the application position, in which the application member 22 can be brought into contact with a part of the human body to be made up.
    In accordance with the present application, the reservoir 10 is equipped with a wiper member 50 disposed near the opening 12 and capable of wringing at least the applicator member 22 of the applicator 20, during the removal of said applicator 20.
    According to the embodiment, the wiper 50 is disposed inside the reservoir 10 at an entrance to the neck 13. The wiper 50 comprises a substantially tubular body comprising at least one wiping portion 51 of which a free interior surface defines a wiper duct 52 adapted to be traversed by the applicator member 22 in a wiping direction.
    The spin direction corresponds substantially to a longitudinal direction of the neck 13 and of the reservoir 10.
    More particularly, the wiper 50 has no attachment portion and only includes the wiping portion 51 which is in the form of a block of elastomeric thermoplastic material.
    In accordance with the present application, the elastomeric thermoplastic material has a hardness of less than 70 Sh 00, preferably less than 45 - 50 Sh 00.
    In this case, the elastomeric thermoplastic material has a hardness of less than 30 Sh 00, preferably less than 20 Sh 00.
    The elastomeric thermoplastic material used is a TPS or TPES, preferably a SEBS. The thermoplastic material used can also belong to the family of TPE gel, allowing very low hardness to be obtained.
    As indicated above, the thermoplastic material may be a single elastomeric thermoplastic or a mixture of elastomeric thermoplastic materials, the mixture of which has the property of targeted hardness. By way of example of usable materials, mention may be made of the PolyOne® materials sold under the references GLS 454-115 (18 Sh 00) and GLS 458-083 (20 Sh A).
    Advantageously, the material used may be a mixture, for example 70/30 by mass or 50/50 by mass depending on the materials used, of elastomeric thermoplastic materials having different hardnesses. The use of a mixture to obtain the desired hardness can in particular make it possible to reduce the total cost of the material by using a high proportion of a harder but less expensive material or vice versa.
    Thanks to the use of an elastomeric thermoplastic material, the wiper can be simply produced according to an injection molding process and makes it possible to avoid any subsequent cutting step unlike the use of a foam block. For all practical purposes, it is also possible to add fillers to the TPE material having certain specific functionalities and for example a bactericidal function (zinc charge, activated carbon, silver or copper for example). The wiper 50 has a wiping portion 51 of cylindrical shape.
    The wiper duct 52 has a length in the wiping direction greater than or equal to a diameter of the wiper duct 52.
    Thus, the length of the wiper duct 52 can conventionally be around 5 to 6 mm.
    As indicated above, the diameter of the wiper duct 52 is determined so as to be less than the maximum diameter of the application member 22.
    Preferably, the diameter of the wiping pipe 52 is less than the minimum diameter of the application member 22 so that the entire application member 22 can be wrung out.
    Thus, the diameter of the wiper duct 52 may conventionally be less than 5 mm.
    Also preferably, the diameter of the wiper duct 52 is substantially equal to or even slightly less than the diameter of the rod 21 so as to also be able to wipe the rod 21 during extraction of the applicator.
    Such a characteristic makes it possible to produce an effective seal at the level of the rod 21 between said rod 21 and the wiping portion. Advantageously, it will be ensured that the tightening, that is to say the difference between the diameter of the wiping duct and the diameter of the rod 21 is at least 0.1 mm, preferably at least 0.2 mm.
    Thus, the diameter of the wiper duct 52 can be conventionally less than or equal to 2 mm. The thickness of the wiping portion 51, in a direction perpendicular to the wiping direction, is greater than or equal to half the diameter of the wiping duct 52, in this case about 0.75 times the diameter of the wiper 52.
    Thus, the thickness of the spin portion can be conventionally between 2 and 6 mm. The wiper 50 is disposed inside the tank 10 at the base of the neck 13 in a wiper holder 17 in the form of a basket attached to a rim of the tank 10 before the hoop 10a forming the col 13.
    The wiper holder 17 has a central orifice 17a coinciding with the wiper duct 52 so as to allow the passage of the applicator member 22.
    As explained above, the size of the orifice can be adjusted as a function of the desired retention of the wiping portion and in particular of the flexural deformation in passing of the application member which is desired.
    Thus, the wiping portion 51 is between a lower shoulder of the neck 13 and the wiper holder 17, an upper surface of said wiping portion 51 coming into contact with an internal surface of a shoulder of the neck.
    In general, the holding zone of the wiping portion 51, here by the shoulder of the neck 13 and the lower surface of the wiper holder 17, can be adapted as a function of the desired flexural deformation when the member passes application.
    Indeed, in the case of a holding zone extending substantially over the entire thickness of the wringing portion, the latter will be blocked in bending in the passage of the applicator member. It is possible to adjust the length of this holding zone so as to allow more or less significant flexural deformation.
    FIG. 2 shows a variant 55 of the wiper 50 comprising, independently of one another, a wiping duct 52 having an upper orifice 53 for insertion of frustoconical section, and a peripheral bead 54 located at a lower end of the spin portion.
    Optionally the lower opening may also have a frustoconical section.
    The presence of a peripheral bead 54 allows, when the wiper 50 is in place in the wiper holder 17, to position it correctly in said wiper holder 17 while keeping the wiping portion 51 spaced from a side wall of the door wringer 17 or tank 10 if applicable.
    The presence of such a clearance relative to a side wall makes it possible to improve the initial deformation of the wiping portion 51 when the applicator member 22 passes before said wiping portion is compressed against the side wall. of the wiper 17 or of the reservoir which holds it.
    According to one embodiment, the height of the peripheral bead 54 is less than or equal to 20% of the height of the wiping portion. Thus, for a wringer having a height of 6mm, the height of the peripheral bead 54 may be approximately 1mm. The thickness of the peripheral bead 54 will depend on the compression delay and the desired elongation work. For example, the thickness of the peripheral bead may be less than or equal to 20% of the thickness of the wiping portion 51 (excluding the thickness of the bead 54). Preferably, the thickness of the peripheral bead will be less than 15%. Thus, for a wringing portion having a thickness of approximately 5mm, the thickness of the peripheral bead will be approximately 0.5mm.
    FIG. 3 shows a packaging and distribution unit 100 which differs from the unit 1 essentially in that it is equipped with a wiper 150 having, in addition to a wiping portion 151 as described above, a attachment portion 152.
    Thus, the wiper 150 is not disposed in a wiper holder 17 but is directly attached to the neck 13 via its hooking portion 152.
    The attachment portion 152 is produced integrally with the spinning portion 151.
    The hooking portion 152 can be produced in the manner of the hooking portions of conventional lip wringers.
    The attachment portion 152 can be made of the same material as the wiping portion or preferably in a more rigid elastomeric thermoplastic material (conventionally having a hardness greater than 20 Shore A) facilitating its attachment and its holding. The use of a different material can be implemented by a bi-injection or overmolding process.
    It will further be noted that the wiping portion 151 also includes an additional duct forming a vent 155, configured to allow air communication between a first interior space of a tank located on one side of the wiping portion and a second space located on an opposite side of the spin portion. The vent 155 extends substantially in a direction transverse to the spin axis, in particular radial.
    The presence of the vent 155 makes it possible to avoid any phenomenon of overpressure or depression (piston effect) during the introduction or extraction of the application member 22 through said wiping portion 152.
    FIG. 4 shows a packaging and distribution assembly 200 differing from assembly 1 essentially by the fact that it is equipped with a wiper 250 having a wiping portion 251 and a coupling portion 252.
    The wiping portion 251 is similar to the wiping portion 50 with the difference that it comprises a frustoconical upper orifice 53 similar to that of the wiper 55.
    Furthermore, the wringing portion 251 is also supported in a wringer holder 17.
    The attachment portion 252 is produced in a single piece with the hoop 10b forming a neck 13.
    Thus, the wiper 150 is not disposed in a wiper holder 17 but is directly attached to the neck 13 via its hooking portion 152.
    Preferably, the attachment portion is made of a material having sufficient rigidity to ensure the good performance of the assembly on the tank 10. The wiper 250 can in particular be produced according to a bi-injection or overmolding process. If necessary, it will be advantageous to provide raised zones making it possible to increase the mechanical strength of the materials between them (cf. for example EP 2 574 252).
    Depending on the rigidity of the material used to make the attachment portion, it is also possible to overmold it at the neck 13.
    FIG. 5 shows a hoop 310b forming a neck 13 and intended to be attached to a corresponding main part of a reservoir of a packaging and distribution assembly.
    The neck 13 is equipped with a wiper 350 according to the present application comprising a wiping portion 351, similar to the wiping portion 251, and a hooking portion 252 configured to cooperate with the neck 13 and ensure the holding of the wringer 350.
    To do this, the hooking portion 252 has an upper peripheral radial rim 253 and a lower peripheral radial rim 254, the flanges 253 and 254 respectively engaging with the free edge 11 of the neck 13 and an internal lower shoulder of the same neck. 13.
    As before, depending on the hardness of the material used, it is possible to overmold the attachment portion to the neck 13, the neck then ensuring the mechanical strength.
    Figures 6 and 7 are photos showing the result of a spin using a foam block wringer according to the prior art (Figure 6) and using a block wringer comprising a wringing portion made in a TPE of hardness 18 Shore 00.
    The difference in spin accuracy is obvious.
