Description

Title of the invention: A refillable packaging assembly for a cosmetic product comprising a refill-forming device and an axial retention device for said refill-forming device within a casing assembly

[0001] The present invention relates to the field of refillable packaging assemblies for a product, in particular cosmetics.

[0002] For the purposes of this invention, "cosmetic product" means, in particular, a product as defined in Regulation (EC) No 1223 / 2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products.

[0003] More particularly, the invention relates to a rechargeable product packaging assembly comprising a container containing a product and a covering assembly for said container, in which the container is mounted.

[0004] The container forms a refill suitable for replacement when the product it contains is exhausted.

[0005] The proposal of eco-responsible, environmentally friendly solutions, whose design and development take into account environmental issues, is becoming a major concern in order to contribute to meeting planetary challenges.

[0006] It is therefore essential to design products that reduce the amount of materials used and / or replace them with more environmentally friendly materials and / or use recyclable materials in order to reduce the carbon footprint of the product.

[0007] In this context, it is important to develop packaging that generates less waste, in particular optimized for the quantity of products transported, notably by redesigning and / or resizing them in order to reduce the volume and weight of the amount of packaging.

[0008] The objective is to offer eco-responsible reusable containers, in particular refillable at home or in stores, in order to reduce the carbon footprint of packaging.

[0009] The present invention is part of this approach to developing refillable packaging for the field of cosmetic products, and in particular skincare or makeup products, especially keratin fibers, in particular eyelashes and / or eyebrows, such as mascara, a lip makeup product, such as lipstick or gloss, or a skin makeup product, such as a complexion corrector, applied to localized areas of the face.

[0010] In a conventional manner, whether in the field of product packaging For cosmetics or other products, refill containers come in the form of minimalist sets, suitable for being combined with packaging elements to form a ready-to-use packaging set offering the user optimal performance, particularly in terms of aesthetics and ergonomics of use.

[0011] Document JP-B2-3638756 is known, describing a refill container mounted in a housing element and held axially in said housing element by a ring rotationally fixed to the housing element. Said ring comprises two projecting portions extending radially inwards, each intended to be selectively positioned opposite a shoulder provided on the refill container in an axial holding position, thus preventing its axial extraction from the housing element, and opposite a flat surface provided on the shoulder of the container to allow its axial extraction from the housing element.

[0012] Such a solution makes it easy to replace the container forming the refill.

[0013] However, axial play may remain between the shoulder of the container forming the refill and the axial retaining ring when said container is held axially in the cladding element, which may impair the perceived quality of the assembly.

[0014] Furthermore, in the event of accidental rotation of the axial retaining ring, there is a significant risk of unexpected axial extraction of the container forming the refill outside of the housing element.

[0015] Document CN217285031 is also known, which provides an axial retaining ring for a refill container within a housing element comprising a snap button designed to engage with a notch on the refill container in an axially retained position. To detach the refill container from the housing element, the user presses the snap button radially to elastically deform the axial retaining ring and disengage the snap button from the notch on the refill container.

[0016] However, when the container forming the refill is separated from the housing element, the axial retaining ring is also separated, so there is a risk of loss of said ring.

[0017] Furthermore, in the event of accidental pressing of the pressure button, there is a significant risk of undesired axial extraction of the container forming the refill outside of the dressing element.

[0018] Although offering a refillable solution for refillable cosmetic product packaging assemblies, the design of the axial retaining rings according to these documents does not give complete satisfaction.

[0019] The present invention therefore aims to overcome the above drawbacks and to improve refillable product packaging assemblies comprising a refill container and a cover element with the aim of improving the axial retention of said refill container relative to the cover element in a product use position and facilitating the extraction of the refill container from the cover element in case of replacement of said refill container.

[0020] Another objective of the invention is to improve the user's perception of quality and to avoid any unexpected extraction of the refill container.

[0021] The invention relates to a refillable packaging assembly for a product, particularly a cosmetic product, extending axially along a longitudinal axis and comprising at least: - a refillable device comprising a container or bottle defining an internal volume intended to receive the product, and - a set of enclosures delimiting an internal space for receiving the charging device.

[0022] The refillable packaging assembly includes an axial retention device for the container relative to the casing assembly comprising: - at least one flexible tab extending axially along the longitudinal axis of the refillable packaging assembly and comprising an internal snap-on element; and - at least one additional external snap-in element carried by the container and intended to cooperate with an internal snap-in element of the flexible leg of the enclosure assembly in an axial retaining position of the container relative to the enclosure assembly.

[0023] The flexible leg is elastically deformable in the radial direction between an initial position in which said flexible leg extends axially along a first axis substantially parallel to the longitudinal axis and a deformed position in which said flexible leg extends along a second axis forming an angle with the longitudinal axis.

[0024] By "flexible" or "elastically deformable", we mean any part capable of deforming under the action of an applied stress, for example the crossing of the snap-in elements resulting from an extraction force applied to the device forming the refill and tending to extract it from the housing assembly, and of returning to its initial shape after the cessation of said stress.

[0025] The axial retention device ensures axial retention of the container of the refilling device relative to the casing assembly.

[0026] By "product" we mean a fluid or semi-fluid product, such as, for example, a skincare or makeup product, in particular lip makeup, or a skincare or makeup product for a user's epidermis.

[0027] According to one embodiment, the axial retention device of the container relative to the casing assembly comprises at least two circumferentially distributed flexible tabs, for example regularly or not, around the casing assembly.

[0028] Preferably, the two flexible legs are diametrically opposed.

[0029] The axial retention of the container of the refilling device relative to The entire housing assembly, via at least two flexible tabs, improves the stability of said axial support.

[0030] According to one embodiment, the additional external snap-on element provided on the container may be unique, for example in the form of a rib or a circumferential groove and cooperate with a single flexible leg or a plurality of flexible legs.

[0031] Generally, the complementary external snap-fit ​​element may be in the form of a continuous or discontinuous rib or groove in the circumferential direction. In the latter case, the rib or groove segments are adapted to cooperate with an internal snap-fit ​​element of a corresponding flexible leg.

[0032] Advantageously, the refillable packaging assembly further includes a locking / unlocking device for the axial retaining device of the container relative to the casing assembly.

[0033] Alternatively, the rechargeable packaging assembly could be provided for without such a locking / unlocking device.

[0034] Advantageously, the locking / unlocking device includes an axial retaining ring, axially attached to the housing assembly and comprising at least one radial projection extending radially inwards.

[0035] The axial retaining ring is movable in rotation about the longitudinal axis relative to the casing assembly between a locked position, in which the radial projection is at the rear in the radial direction of the flexible leg provided with an internal snap-in element to block the bending of said leg in the radial direction and thus prevent the manual extraction of the container from the casing assembly and an unlocked position, in which the radial projection is offset angularly from the flexible leg provided with an internal snap-in element to allow the bending of said flexible leg in the radial direction and thus allow the manual extraction of the container from the casing assembly by means of an axial extraction force applied on said container, causing the radial spreading of the flexible leg provided with an internal snap-in element.

[0036] The locking / unlocking device ensures reliable axial retention of the rechargeable device in the housing assembly.

[0037] The axial retention device improves the quality of axial support of the device forming a refill in the housing assembly, advantageously without play while limiting the risk of unexpected extraction of the device forming a refill in the event of accidental rotation of the axial retaining ring.

[0038] The axial retaining ring is fixed in rotation to the entire housing assembly, in particular to the bracket.

[0039] Alternatively, a different number of radial projections of the axial retaining ring could be provided.

[0040] Generally, the number of radial projections of the axial retaining ring corresponds to the number of flexible tabs equipped with an internal snap-in element.

[0041] Advantageously, the axial retaining ring is rigid, that is to say, it is not elastically deformable.

[0042] According to one embodiment, the casing assembly comprises a closed lower end forming a bottom, an open upper end, opposite the bottom, provided with a neck and allowing access to the internal receiving space of the container and a peripheral side wall extending between the bottom and the open upper end.

[0043] For example, the flexible tab is supported by the collar of the garment assembly. In the case where there are several flexible tabs, each of the flexible tabs is supported by the collar of the garment assembly.

[0044] According to one embodiment, the collar of the clothing assembly comprises two groups of three flexible tabs, said flexible tabs of each group being spaced by a first circumferential distance and the two groups being spaced from each other by a second circumferential distance.

[0045] For example, the first circumferential set is less than or equal to the second circumferential set.

[0046] For example, the second circumferential clearance is between the angular range of a flexible leg and the angular range of a flexible leg plus the first two circumferential clearances.

[0047] Alternatively, the collar of the clothing assembly could be provided to include at least three circumferentially flexible tabs, preferably regularly spaced from each other.

[0048] Advantageously, at least one flexible leg of each group of three flexible legs is provided with an internal snap-in element.

[0049] Alternatively, at least two flexible legs of each group of three flexible legs are each provided with an internal snap-locking element.

[0050] The internal snap-in element is, for example, located at the upper free end of the flexible leg.

[0051] For example, the two flexible legs located at the circumferential ends of each group of three flexible legs are each provided with an element internal snap-lock.

[0052] For example, the internal snap-on element carried by the flexible leg is an internal bead projecting radially inwards, and the complementary snap-on element carried by the container is an external bead projecting radially outwards or a groove.

[0053] Thus, in the case of a plurality of flexible legs, the neck of the dressing assembly includes a discontinuous snap-fit ​​groove in the circumferential direction, i.e. formed of a plurality of snap-fit ​​ridges separated from each other in the circumferential direction and fitting axially under a complementary snap-fit ​​ridge or in a complementary snap-fit ​​groove, carried by the container.

[0054] The additional snap-lock bead or the additional snap-lock groove may be annular or discontinuous in the circumferential direction.

[0055] Advantageously, the internal snap-in elements carried by the flexible legs are circumferentially regularly distributed.

[0056] According to one embodiment, the axial retaining ring comprises at least one radial rib and the neck of the housing assembly comprises at least one external snap-in element intended to cooperate with said radial rib to axially secure said ring to the housing assembly.

[0057] According to one embodiment, at least one flexible leg of each group of flexible legs includes an external snap-in element.

[0058] For example, the external snap-in element includes a radially outward projecting bead and a snap-in groove located axially directly under said bead and intended to cooperate with the radial rib provided on the axial retaining ring.

[0059] For example, an external snap-fit ​​element extends into each of the second circumferential sets.

[0060] Alternatively, it could be provided that the second circumferential sets are devoid of any flexible tab or internal snap-in element.

[0061] For example, the external snap-in elements are carried or not by the same flexible tabs as those carrying the internal snap-in elements.

[0062] According to one embodiment, the axial retaining ring comprises, on its inner wall, at least one axial rib extending axially at least over a portion of the height of the axial retaining ring.

[0063] According to another embodiment, the axial retaining ring comprises, on its inner wall, at least two axial ribs extending axially at least over a portion of the height of the axial retaining ring and each intended to fit between two flexible tabs in the locked position of the ring, particularly in the first set circumferential, thus forming a tactile and / or audible indication device for the positioning of the ring, particularly in the locked position.

[0064] For example, the axial ribs are located circumferentially opposite each other.

[0065] For example, an axial rib is circumferentially situated between two radial projections.

[0066] For example, the axial ribs have a semi-circular cross-section so that they can be easily crossed by the flexible tab during the rotation of the ring.

[0067] According to one embodiment, the axial retaining ring comprises, on its inner wall, at least one circumferential stop extending radially inwards and intended to bear circumferentially against the flexible tab in the locked position of the ring, thus forming a circumferential stop device in the locked position.

[0068] According to one embodiment, the axial retaining ring comprises, on its inner wall, at least two circumferential stops extending radially inwards and each intended to bear circumferentially against one of the flexible tabs in the locked position of the ring, in particular to insert into the second circumferential set.

[0069] For example, the two circumferential stops are located circumferentially opposite each other.

[0070] For example, a circumferential stop is circumferentially located between two radial projections.

[0071] Advantageously, the circumferential stops and axial ribs are arranged alternately and circumferentially, preferably regularly, spaced apart from each other.

[0072] For example, the axial retaining ring comprises an outer wall, for example of polygonal cross-section, and an inner wall of circular cross-section.

[0073] Alternatively, other cross-sectional shapes of the external wall of the axial retaining ring could be provided, such as a circular, ovoid, oblong, polygonal shape, for example square or rectangular, in particular with rounded corners, or other.

[0074] The cross-section of the outer wall of the axial retaining ring can be identical and of the same dimensions as the cross-section of the housing so as not to form radial protrusions. This limits the risk of unexpected actuation of the axial retaining ring.

[0075] Conversely, the cross-section of the outer wall of the axial retaining ring may be different and / or of different dimensions than the cross-section of the casing, in order to form one or more radial protrusions on the axial retaining ring protruding from the casing, and this in order to facilitate the gripping and actuation of the ring axial support.

[0076] According to one embodiment, the container of the refilling device comprises a main body extending along the longitudinal axis and an added element, fixed on the main body and defining a neck and a shoulder of the container.

[0077] Alternatively, it could be envisaged that the main body and the added element form a single piece of the container.

[0078] Generally, the refilling device includes a side wall extending between the bottom and the neck and connected to the latter via the shoulder.

[0079] By "shoulder" we mean any surface substantially normal to the elevation axis of a cylindrical part, here the longitudinal axis of the container, resulting from a sudden variation in diameter, or more generally in dimension in the radial direction, orthogonal to the longitudinal axis.

[0080] Advantageously, the main body of the container is provided with a closed lower end forming a bottom and an open upper end, opposite the lower end, provided with an opening allowing access to the internal volume for receiving the product.

[0081] The open end is, for example, connected to the bottom by a step extending inwards in the radial direction and a groove located axially between the step and the open end.

[0082] The added element is, for example, fixed at the open end of the main body.

[0083] For example, the added element comprises a sealing skirt mounted by its open end in the main body and a fixing skirt extending radially around the sealing skirt. The fixing skirt forms the side wall of the added element.

[0084] The fixing skirt is connected to the collar via the shoulder and defines, with the sealing skirt, an annular space for receiving the portion of the main body extending between the step and the open end.

[0085] The fixing and securing in translation along and in rotation around the longitudinal axis of the element attached to the main body is preferably ensured by the cooperation of the groove, in particular discontinuous in the circumferential direction, i.e. formed of a plurality of cavities separated from each other in the circumferential direction, and of a gadroon, in particular discontinuous in the circumferential direction, i.e. formed of a plurality of bosses separated from each other in the circumferential direction and received in the corresponding cavities of the groove.

[0086] The side wall of the bottle is defined by the side wall of the main body located between the bottom and the notch, and by the fixing skirt of the added element. Preferably, the recess and the fixing skirt are dimensioned so that the outer surface of the side wall of the main body located between the bottom and the recess is flush with the outer surface of the fixing skirt, when the added element is fixed to the main body.

[0087] According to one embodiment, the dressing assembly includes a dressing case and a mounting bracket or stirrup, fixed on the dressing case and defining the neck and in particular the shoulder of the dressing assembly.

[0088] Alternatively, the housing and mounting bracket could be provided for as a single piece.

[0089] For example, the dressing case has a closed lower end forming a base and an open upper end, opposite the lower end, having an opening allowing access to an internal space for receiving the container, the mounting bracket being fixed at the open end of the dressing case.

[0090] Advantageously, the open end is connected to the bottom by a peripheral wall of the housing assembly and in which said peripheral wall includes, on its internal surface, an axial groove extending axially from the open end and intended to cooperate with a radial collar provided at the lower end of the mounting bracket.

[0091] According to a particular arrangement, the peripheral wall of the casing assembly has at least one circumferential through-window or opening, allowing the user to view part of the container of the refilling device through the casing assembly when it is received inside it.

[0092] For example, the mounting bracket is fixed to the casing by any suitable means, for example, by gluing, screwing or snapping.

[0093] For example, the peripheral wall of the mounting bracket is discontinuous and includes at least one flexible tab extending axially from the radial flange.

[0094] The flexible leg extends axially from the radial collar and is flexible in the radial direction, i.e. capable of deforming radially in an elastic manner under the action of an external stress, here the crossing of a complementary snap-fit ​​element provided on the container, in particular the added element, resulting from an extraction force applied on the device forming the refill and tending to extract it from the casing assembly, and to return to its initial position after the cessation of the external stress.

[0095] According to one embodiment, the container, in particular the added element, further comprises at least one rotation-blocking element, for example in the form of two axial tabs, intended to be inserted circumferentially between two flexible tabs, or groups of flexible tabs, in particular in said second circumferential set, to block the rotation of the container relative to the casing assembly, particularly at the mounting bracket.

[0096] Thus, the fixing and securing in translation along and in rotation around the longitudinal axis of the element attached to the mounting bracket is, in the illustrated embodiment, ensured by the cooperation of the snap-in ridges, and by the cooperation of the axial tabs each with a second circumferential set.

[0097] According to one embodiment, the refilling device includes a sealing element mounted on the container and sealing access to the internal volume.

[0098] According to one embodiment, the sealing element belongs to a cosmetic product application subset, further comprising an application member extending into the internal volume of the container when the sealing element seals the container and a stem connecting the sealing element and the application member.

[0099] For example, the neck of the device forming the refill is provided with an external thread in the radial direction cooperating with an internal thread provided on the sealing element.

[0100] According to one embodiment, the packaging assembly further includes a cover for dressing and gripping the device forming the refill.

[0101] For example, the sealing element has a central axis coinciding with the longitudinal axis of the container when the sealing element seals it and includes means for securing in translation along the central axis and means for securing in rotation around the central axis to the covering and gripping hood.

[0102] According to a second aspect, the invention relates to a method for refilling a refillable cosmetic product packaging assembly as described above, comprising at least the steps of: - apply an axial extraction force outwards in order to cause the flexible tab equipped with an internal snap-in element of the housing assembly, in particular of the mounting bracket, to be separated under the effect of the additional external snap-in element provided on the container, in order to extract, preferably manually, said container of the used refilling device from the housing assembly; - provide a new charging device; and - insert and fix said new refilling device in the internal space of the casing assembly, until the axial retention device formed by the cooperation between the internal snap-in element of the casing assembly and the complementary external snap-in element provided on the container is snapped into place.

[0103] Advantageously, the refillable packaging assembly comprises an axial retaining ring axially fixed to the casing assembly and comprising at least one radial projection extending radially inwards, said ring being rotationally movable relative to the casing assembly. The refilling method This then advantageously includes, before the step of applying an axial withdrawal force, a step consisting of: - rotate the axial retaining ring in a first direction of rotation until the radial projection of said ring is angularly offset from the flexible tab equipped with the internal snap-in element of the housing assembly; and, advantageously comprising, after the step of inserting and securing a new refilling device, a step consisting of: - rotate the axial retaining ring in a second direction of rotation, opposite to the first direction of rotation, until the radial protrusion of said ring is radially behind the flexible tab provided with the internal snap-in element and thus lock the axial retaining device in the axial retaining or snap-in position.

[0104] According to a particular arrangement, the refillable assembly further comprises a cover and gripping mechanism for the refilling device. The refilling process then advantageously comprises, preferably before the step of rotating the axial retaining ring in the first direction of rotation, a step consisting of removing a cover and gripping mechanism from a sealing element belonging to the used refilling device, and then comprising, preferably after the step of rotating the axial retaining ring in the second direction of rotation, a step consisting of repositioning the cover and gripping mechanism onto the new refilling device that was fitted to the used refilling device.

[0121] In the following description, we consider an orthonormal basis X, Y, Z, with Z corresponding to an axis of elongation representing the vertical direction in which we find:

[0122] - a longitudinal axis X, horizontal and extending from left to right on the [Fig.5];

[0123] - a horizontal transverse axis Y, perpendicular to the longitudinal axis X and extending from front to back on the [Fig. 5]; and

[0124] - a vertical axis Z, orthogonal to the longitudinal axis X and transverse axis Y and extending from bottom to top on the [Fig.5].

[0125] The terms "upper" and "lower" refer to the upper and lower parts of the figures, in the assembled position of the rechargeable unit.

[0126] As illustrated in Figures 1 to 7, a rechargeable product packaging assembly 1 extends axially along an X-X' axis assumed to be vertical on the [Fig.1].

[0127] The rechargeable packaging assembly 1 of a product includes a refill-forming device 10 and a casing assembly 100 delimiting an internal space E for receiving the refill-forming device 10.

[0128] The refilling device 10 comprises a container 2, 3 or bottle or reservoir delimiting an internal volume V intended to contain a product, in particular a cosmetic, and a sealing element 4, illustrated in figures 4 and 5 in the sealing position of the container 2, 3.

[0129] The term “product” means a fluid or semi-fluid product, such as, for example, a skincare or makeup product, in particular lip makeup, or a skincare or makeup product for a user.

[0130] Such a refill-forming device 10 is intended to be associated with the casing assembly 100 to form the refillable cosmetic product packaging assembly 1 and to be able to be replaced at the end of its life by a new refill-forming device, as will be described in more detail later.

[0131] As illustrated, and in no way limiting, the rechargeable packaging assembly 1 of a product includes a cover 8, 9 for dressing and gripping the device forming the refill 10.

[0132] In the embodiment illustrated in the figures, the refilling device 10 comprises a main body 2 extending along the longitudinal axis X-X' and an added element 3, fixed on the main body 2 and defining a neck 30 and a shoulder 31 of the container 2, 3.

[0133] Alternatively, it could be envisaged that the main body 2 and the added element 3 form a single piece.

[0134] As illustrated in detail in Figures 1 to 7, the main body 2 of the container is provided with a closed lower end forming a bottom 20 and an open upper end 22, opposite the lower end 20, provided with an opening O allowing access to the internal volume V for receiving the product.

[0135] Furthermore, and as can be seen in particular on [Fig.2], the neck 30 of the device forming the refill 10 is provided with an external thread 32 in the radial direction.

[0136] In the illustrated embodiment, the added element 3 is fixed at the open end 22 of the main body 2.

[0137] Generally, the refilling device 10 comprises a side wall 21, 33 extending between the bottom 20 and the neck 30 and connected to the latter via the shoulder 31.

[0138] By "shoulder" we mean any surface substantially normal to the elevation axis of a cylindrical part, here the longitudinal axis X-X' of the bottle, resulting from a sudden variation in diameter, or more generally in dimension in the radial direction, orthogonal to the longitudinal axis X-X'.

[0139] The open end 22 is connected to the bottom 20 by a step 23 extending inwards in the radial direction and a groove 24 situated axially between the step 23 and the open end 22.

[0140] The added element 3 comprises a sealing skirt 34 mounted by the open end 22 in the main body 2 and a fixing skirt 36 extending radially around the sealing skirt 34. The fixing skirt 36 forms the side wall 33 of the added element 3.

[0141] The fixing skirt 36 is connected to the collar 30 via the shoulder 31 and defines with the sealing skirt 34, an annular space for receiving the portion of the main body 2 extending between the step 23 and the open end 22.

[0142] The fixing and securing in translation along and in rotation around the longitudinal axis X-X' of the added element 3 on the main body 2 are, in the illustrated embodiment, ensured by the cooperation of the groove 24, in particular discontinuous in the circumferential direction, i.e. formed of a plurality of cavities separated from each other in the circumferential direction, and of a gadroon 35, in particular discontinuous in the circumferential direction, i.e. formed of a plurality of bosses separated from each other in the circumferential direction and received in the corresponding cavities of the groove 24.

[0143] However, those skilled in the art may provide other solutions for securing the attached element 3 to the main body 2 in translation along and in rotation about the longitudinal axis X-X', such as the cooperation of a continuous groove in the circumferential direction provided on the main body 2 and a continuous groove in the circumferential direction provided on the attached element 3 to ensure axial retention of the attached element 3 on the main body 2, combined with the cooperation of at least one and preferably a plurality of axial grooves provided on the main body 2, being regularly distributed around the longitudinal axis X-X', and of at least one and preferably a plurality of axial ribs provided on the attached element 3 to ensure rotational coupling about the longitudinal axis X-X' of the added element 3 and the main body 2. Such axial grooves and axial ribs can in particular form together a grooved system enabling the rotational coupling around the longitudinal axis X-X' of the added element 3 and the main body 2.

[0144] Furthermore, in the embodiment illustrated in the figures, the side wall of the container is defined by the side wall 21 of the main body 2 located between the bottom 20 and the recess 23, and by the fixing skirt 36 of the added element 3. Preferably, the recess 23 and the fixing skirt 36 are dimensioned so that the outer surface of the side wall 21 of the main body 2 located between the bottom 20 and the recess 23 is flush with the outer surface of the fixing skirt 36, when the added element 3 is fixed on the main body 2.

[0145] As illustrated, the fastening skirt 36 includes a bead or rib external snap-fit ​​37 projecting radially from the external surface of said skirt 36 outwards.

[0146] The external snap-on bead 37 can be continuous or discontinuous and is configured to cooperate with an internal snap-on element 126 of the casing assembly 100.

[0147] The device forming a refill 10 according to the invention further includes a sealing element 4 for the container 2, 3.

[0148] As can be seen in particular in figures 2 to 7 and 9, the sealing element 4 has a plate 40 extending transversely to the opening O of the neck 30 when the sealing element 4 seals the container 2, 3, as illustrated in these figures.

[0149] The sealing element 4 also has a fixing skirt 41 erected from the plate 40, provided with an internal thread 42 in the radial direction adapted to cooperate with the external thread 32 of the neck 30 when the sealing element 4 seals the container 2, 3.

[0150] As can be seen in particular in figures 2 to 7, the fixing skirt 41 of the sealing element 4 has a front edge 43 facing the shoulder 31 along the longitudinal axis X-X' when the sealing element 4 seals the container 2, 3.

[0151] The sealing element 4 further has a sealing skirt 46 extending inside the fixing skirt 41 in the radial direction, being coaxial with it and adapted to cooperate with the inner wall of the neck 30 of the container 2, 3 to ensure the sealing of the refilling device 10 according to the invention when the sealing element 4 seals the container 2, 3.

[0152] In the embodiment illustrated in the figures, and without limitation, the sealing element 4 belongs to a cosmetic product application subassembly, also referred to as a plunge applicator, further comprising an application member 6 extending into the internal volume V of the container 2, 3 when the sealing element 4 seals the container 2, 3 and a rod 5 connecting the sealing element 4 and the application member 6. Such an application sub-assembly is particularly intended for the precise application by means of the application member 6 of a cosmetic product contained in the internal volume V of the container 2, 3 on relatively small body areas of a user, such as the application of a keratin fiber makeup product, in particular of eyelashes and / or eyebrows, such as mascara, a lip makeup product, such as lipstick or gloss, or a skin makeup product, such as a complexion corrector, applied to localized areas of the face.

[0153] In order to benefit from an optimal user experience, particularly in terms of ergonomics and application precision, the application sub-assembly 4 is removably connected to the covering and gripping hood 8, 9, as will be described in more detail below.

[0154] The sealing element 4 has a central axis coinciding with the longitudinal axis X-X' of the container 2, 3 when the sealing element 4 seals it and includes means for translational fastening along the central axis and means for rotational fastening around the central axis to a covering and gripping cover 8, 9.

[0155] As seen in particular in figures 2 to 7, in the illustrated embodiment, the means for translational fastening along the central axis include a groove 44 formed on an external surface in the radial direction of the fixing skirt 41 of the sealing element 4. This groove 44, for example continuous in the circumferential direction, is adapted to receive a groove 94, continuous or preferably discontinuous in the circumferential direction, formed on an internal surface in the radial direction of the covering and gripping cover 8, 9.

[0156] Furthermore, and as can be seen in particular in figures 4 to 7, the means for rotational locking around the central axis include a housing 45 with a non-circular cross-section formed on the plate 40 of the sealing element 4. As can be seen in Figures 2 to 7, the housing 45 has a flat surface to define a non-circular cross-section. This housing 45, with its non-circular cross-section, is adapted to receive a pin 95 with a complementary cross-section, provided on the cover and grip 8, 9.

[0157] The cover for dressing and gripping 8, 9 defines a housing L for receiving the sealing element 4.

[0158] The covering and gripping cover 8, 9 has a base 80, a peripheral wall 81 extending from the base 80, and a front edge 93 at least partially facing the shoulder 31 of the container 2, 3 along the longitudinal axis X-X' when the covering and gripping cover 8, 9 receives the element within it sealing 4 sealing container 2, 3.

[0159] The cover and gripping hood 8, 9 has means for translational fastening along the central axis of the sealing element and complementary means for rotational fastening around the central axis of the sealing element 4, adapted to cooperate with complementary means provided on the sealing element 4 to ensure rotational and translational fastening of the sealing element 4 and the cover and gripping hood 4 around the central axis.

[0160] In the embodiment illustrated in the figures, the cover for dressing and gripping is made in two parts and includes an internal element, forming here a rod holder 9, and an external element, forming here a dressing tube 8, housing the internal element 9 and attached to it.

[0161] The internal element 9 comprises an external cylindrical surface 9a in contact with an internal cylindrical surface 8a of the external element 8.

[0162] The fixing of the internal element 9 inside the external element 8 is, for example, achieved by clamping and / or by means of a layer of glue.

[0163] As illustrated in [Fig.5], and in no way limitingly, the inner cylindrical surface 8a of the outer element 8 comprises a plurality of longitudinal grooves or striations 8b parallel to each other and delimiting between each other longitudinal ribs configured to deform when the inner element 9 is inserted into the outer element 8 and to ensure the clamping of the inner element 9 relative to the outer element 8.

[0164] Alternatively, it could be provided that the outer cylindrical surface 9a of the inner element 9 comprises a plurality of longitudinal grooves or striations or that both the inner element 8 and the outer element 9 comprise such grooves.

[0165] As seen in figures 4 to 7, the internal element 9 of the cover and gripping hood has a groove 94 formed on its radially internal surface and received inside the groove 44 of the sealing element 4 to ensure axial retention along the central axis of the cover and gripping hood 8, 9 on the sealing element 4, the groove 44 and the groove 94 forming the complementary means of translational fastening along the central axis of the cover and gripping hood 8, 9 and the sealing element 4.

[0166] Furthermore, and as can be seen in Figures 4 to 7, the internal element 9 of the cover and gripping mechanism has a pin 95 with a cross-section complementary to the non-circular cross-sectional housing 45 provided on the plate 40 of the sealing element 4. When the cover and gripping mechanism 8, 9 is placed on the sealing element 4, the pin 95 is inserted inside the housing 45 and, together with it, forms the complementary means of securing it. rotation around the central axis of the cover and grip 8, 9 and the sealing element 4.

[0167] The dressing assembly 100 includes a dressing case 101 and a mounting bracket or stirrup 102, fixed to the dressing case 101 and defining a neck 103 and a shoulder 104 of the dressing assembly 100.

[0168] Alternatively, the housing 101 and the mounting bracket 102 could be provided to form a single piece.

[0169] As illustrated in detail in figures 2 to 7, the dressing case 101 is provided with a closed lower end forming a base 110 and an open upper end 112, opposite the lower end 110, provided with an opening 02 allowing access to an internal space E for receiving the container 2, 3.

[0170] The base 20 of the device forming the refill 10 is, here, axially spaced from the base 110 of the casing assembly 100.

[0171] In the illustrated embodiment, the mounting bracket 102 is fixed at the open end 112 of the dressing case 101.

[0172] Generally, the casing assembly 100 includes a peripheral side wall 111, 121 extending between the bottom 110 and the neck 103 and connected to the latter via the shoulder 104.

[0173] The open end 112 is connected to the bottom 110 by the peripheral wall 111.

[0174] The peripheral wall 111 of the case 101 includes, on its internal surface, an axial groove 113 extending axially from the open end 112 and intended to cooperate with a radial collar 122 provided at the lower end of the mounting bracket 102.

[0175] The mounting bracket 102 is fixed to the cover case 101 by any suitable means, for example, by gluing, screwing or snapping.

[0176] As seen in detail in Figures 2 to 7, the peripheral wall 121 of the mounting bracket 102 is discontinuous and comprises a plurality of flexible tabs 123 extending axially from the radial flange 122 and spaced apart from each other in the circumferential direction.

[0177] Alternatively, the peripheral wall 121 of the mounting bracket 102 could be provided to include only a flexible tab 123.

[0178] In the example illustrated in [Fig. 2A], the peripheral wall 121 of the mounting bracket 102 comprises two groups of three flexible tabs 123a, 123b, the tabs 123 of each group 123a, 123b being spaced by a first circumferential clearance J1 and the two groups being spaced from each other by a second circumferential clearance J2. The first circumferential clearance J1 is less than the second circumferential clearance J2.

[0179] For example, the second circumferential clearance J2 is between the angular range of a flexible leg and the angular range of a flexible leg plus two first circumferential games Jl.

[0180] Alternatively, the peripheral wall 121 could be provided to include at least three circumferentially, preferably regularly spaced, flexible tabs.

[0181] As illustrated, each flexible leg of each leg group includes an external snap-in element 124, here a radially outward projecting bead, defining with the radial collar 122, a snap-in groove 125 intended to cooperate with a radial rib 151 provided on an axial retaining ring 105.

[0182] Generally, at least one flexible leg 123 of the mounting bracket 102 includes an external snap-in element 124, 125 intended to cooperate with a complementary snap-in element 151, here a radial rib, discontinuous or continuous, provided on the axial retaining ring 105 to axially secure said ring 105 to the housing assembly 100.

[0183] In the illustrated example, an external snap-fit ​​element 124 extends into each of the second circumferential sets J2. Alternatively, the second circumferential sets J2 could be provided to be devoid of any flexible tab or external or internal snap-fit ​​element.

[0184] As illustrated, two of the flexible legs of each leg group include, at their upper free end, an internal snap-fit ​​element 126, here an internal bead projecting radially inwards, intended to fit into the rear of the complementary external snap-fit ​​bead or rib 37 provided on the added element 3, in particular on the fixing skirt 36.

[0185] The internal snap-in elements 126 are circumferentially regularly distributed.

[0186] It could be envisaged that the internal snap-in elements 126 may or may not be provided on the same flexible tabs as those carrying the external snap-in elements 124, 125.

[0187] Generally, at least one flexible leg 123 of the mounting bracket 102 includes an internal snap-in element 126 intended to cooperate with an additional external snap-in element 37 provided on the added element 3 to axially retain said added element 3 on the housing assembly 100.

[0188] In other words, the refillable packaging assembly 1 includes an axial retention device for the container forming the refill 2, 3 relative to the casing assembly 100, employing at least one internal snap-on element 126 carried by a flexible tab 123 of the casing assembly 100 and a complementary external snap-on element 37 carried by the container 2, 3.

[0189] Preferably, the refillable packaging assembly 1 includes an axial retention device for the refill container 2, 3 relative to the assembly 100 cladding employing at least two internal snap-fit ​​elements 126 each carried by a flexible tab 123 of the cladding assembly 100 and one or more complementary external snap-fit ​​elements 37 carried by the container 2,3.

[0190] The additional external snap-fit ​​elements 37 carried by the container 2, 3 are here snap-fit ​​ridges, circumferentially regularly distributed around the housing assembly 100 and separated by circumferential spaces.

[0191] The snap-on tabs 123 extend axially from the radial collar 122 and are flexible in the radial direction, i.e. capable of deforming radially in an elastic manner under the action of an external stress, here the crossing of a complementary snap-on element 37 provided on the added element 3 resulting from an extraction force applied on the device forming the refill 2, 3 and tending to extract it from the housing assembly 100, and to resume its initial position after the cessation of the external stress.

[0192] The axial retention device ensures axial retention of the container 2, 3 relative to the casing assembly 100.

[0193] The added element 3 further includes a rotation blocking element, here two axial tabs 38 extending axially downwards from the shoulder 31 and extending over an angular range less than or equal to the angular range of the second circumferential set J2 of the mounting bracket 102 in order to insert circumferentially into said second set J2 and to block the rotation of the added element 3 with respect to the mounting bracket 102 and thus to the housing assembly 100.

[0194] The fixing and securing in translation along and in rotation around the longitudinal axis X-X' of the added element 3 on the mounting bracket 102 is, in the illustrated embodiment, ensured by the cooperation of the external snap-in lugs 37 and internal 126, and by the cooperation of the axial tabs 38 each with the tabs 123 defining the second circumferential set J2.

[0195] In the illustrated embodiment, the packaging assembly 1 includes a locking / unlocking device for the axial retaining device of the container 2, 3 relative to the casing assembly 100.

[0196] Alternatively, it could be provided that the refillable packaging assembly 1 is devoid of such a locking / unlocking device.

[0197] The locking / unlocking device uses the axial retaining ring 105, axially attached to the housing assembly 100 and comprising, here, radial projections 152, here four in number, extending radially inwards, and circumferentially regularly spaced from each other.

[0198] Generally, the axial retaining ring 105 includes at least one radial projection 152.

[0199] The axial retaining ring 105 is rotationally movable relative to said assembly 100 between a locked position, in which each radial projection 152 is located at the rear in the radial direction of a flexible tab 126 provided with an internal snap-in element 126 to block their flexion in the radial direction and thus prevent manual extraction of the container 2, 3 from the casing assembly 100, and an unlocked position, in which the radial projections 152 are angularly offset from the flexible tabs 123 provided with an internal snap-in element 126 to allow their flexion in the radial direction and thus allow manual extraction of the container 2, 3 from the casing assembly 100 by means of an axial extraction force applied to said container 2, 3, causing the radial separation of the flexible tabs 123 equipped with an internal snap-in element 126.

[0200] Alternatively, a different number of radial projections 152 of the axial retaining ring 105 could be provided. Generally, the number of radial projections 152 of the axial retaining ring 105 corresponds to the number of flexible tabs 123 provided with an internal snap-in element 126.

[0201] As illustrated in detail in Figures 8A and 8B, the axial retaining ring 105 comprises an outer wall 153, here of polygonal cross-section, and an inner wall 154 of circular cross-section.

[0202] Alternatively, other cross-sectional shapes of the outer wall 153 of the axial retaining ring 105 could be provided, such as a circular, ovoid, oblong, polygonal shape, for example square or rectangular, in particular with rounded corners, or other.

[0203] The section of the outer wall 153 of the axial retaining ring 105 can be identical and of the same dimension as the section of the dressing case 101 so as not to form radial protrusions.

[0204] Conversely, and as illustrated, the cross-section of the outer wall 153 of the axial retaining ring 105 may be different and / or of different dimensions than the cross-section of the dressing case 101, in order to form one or more radial protrusions on the axial retaining ring 105 protruding from the dressing case 101, and this in order to facilitate the gripping and actuation of the axial retaining ring 105.

[0205] As illustrated, the axial retaining ring 105 comprises, on its inner wall 154, radial ribs 151, here four in number, extending radially inwards, and circumferentially regularly spaced from each other.

[0206] Generally, the axial retaining ring 105 includes at least one radial rib 151.

[0207] As illustrated, the axial retaining ring 105 further comprises, on its inner wall 154, two axial ribs 155 extending axially at least over a portion of the height of the axial retaining ring 105.

[0208] The two axial ribs 155 are, here, located circumferentially opposite each other.

[0209] An axial rib 155 is circumferentially situated between two radial projections 152.

[0210] Each axial rib 155 is intended to fit into the first circumferential set J1 between two flexible tabs 123 and form a tactile and / or audible indication device for the positioning of the ring 105, particularly in the locked position.

[0211] The axial ribs 155 here have a semi-circular cross-section in order to be easily crossed by the flexible tabs 123 during the rotation of the ring 105.

[0212] Generally, the axial retaining ring 105 includes, on its inner wall 154, at least one axial rib 155 extending axially at least over a part of the height of the axial retaining ring 105.

[0213] As illustrated, the axial retaining ring 105 comprises, on its inner wall 154, two circumferential stops 156 extending radially inwards.

[0214] The two circumferential stops 156 are, here, located circumferentially opposite each other.

[0215] A circumferential stop 156 is circumferentially located between two radial projections 152.

[0216] Each circumferential stop 156 is intended to be inserted into the second circumferential set J2 and to bear circumferentially against a flexible tab 123 and form a circumferential stop device in the locked position.

[0217] The circumferential stops 156 and the axial ribs 155 are arranged alternately and regularly spaced from each other.

[0218] Generally, the axial retaining ring 105 includes, on its inner wall 154, at least one circumferential stop 156 extending radially inwards.

[0219] We will now describe a disengageable anti-opening device equipping the refillable cosmetic product packaging assembly according to the invention, in particular in relation to figures 10 to 13.

[0220] As can be seen in particular in Figures 10 to 13, the shoulder 31 of the container 2, 3, and here of the added element 3, also has a stop surface 314, and preferably two diametrically opposed stop surfaces 314 exhibiting central symmetry with respect to the longitudinal axis X-X', extending in a plane containing the longitudinal axis X-X'. As will be explained later, this or these stop surfaces 314 are adapted to cooperate with one or more stop surfaces 450 provided on the sealing element 4 to define a screwing limit of the sealing element 4 on the neck 30 of the container 2, 3, corresponding to the position in which the sealing element 4 seals the container 2, 3.

[0221] As can be seen in these figures, the disengageable anti-opening device is arranged between the neck 30 of the container 2, 3 and the sealing element 4 and is adapted to block the rotation of the sealing element 4 relative to the neck 30 of the container 2, 3 in an SD unscrewing direction, when the sealing element is in the sealing position of the container 2, 3.

[0222] More specifically, the disengageable anti-opening device comprises a tab 310, and preferably two diametrically opposed tabs 310 exhibiting central symmetry with respect to the longitudinal axis X-X', each having a first end 311 integral with the shoulder 31 of the container 2, 3 and a second free end 312.

[0223] The tab(s) 310 extend in the circumferential direction, with their second free end 312 located downstream of their first end 311 connected to the shoulder, in the screwing direction SV of the sealing element 4 on the neck 30 of the container 2, 3, and have a capacity to flex in the direction defined by the longitudinal axis X-X'; in other words, the tab(s) 310 are flexible in the axial direction.

[0224] The disengageable anti-opening device equipping the cosmetic product refill packaging assembly according to the invention further comprises one and preferably two diametrically opposed anti-unscrewing stop surfaces 440 having a central symmetry with respect to the longitudinal axis X-X', provided on the sealing element 4. These anti-unscrewing stop surfaces 440 provided on the sealing element 4 are provided to cooperate with the tabs 310 provided on the neck 30 of the container 2, 3 to block the rotation of the sealing element 4 with respect to the neck 30 of the container 2, 3 in an unscrewing direction, when the sealing element 4 is in the sealing position of the container 2, 3, as illustrated in Figures 9 and 13.

[0225] In the embodiment illustrated in the figures, the anti-unscrewing stop surface(s) 440 provided on the sealing element 4 are defined by a respective notch 44 formed in the front edge 43 of the sealing element 4.

[0226] Furthermore, the stop surface(s) provided on the sealing element 4 are defined by a respective cutout 47 formed in the front edge 43 of the sealing element 4.

[0227] The rechargeable device 10 forming a refill is intended to be marketed with the sealing element 4 in the sealing position of the container 2, 3, as illustrated in figures 9 and 13.

[0228] The installation by screwing the sealing element 4 onto the neck 30 of the container 2, 3 to seal it, illustrated in figures 10 to 12, is carried out in the factory or in the packaging center, after filling the internal volume V of the container 2, 3 with a cosmetic product.

[0229] More specifically, and as can be seen in Figures 10 to 12, when screwing the sealing element 4 onto the neck 30 of the container 2, 3, carried out by rotating the sealing element 4 relative to the neck 30 of the container 2, 3 in a screwing direction SV, the tabs 310 are adapted to flex in the axial direction towards the bottom 20 of the container 2, 3 by contact with the front edge 43 of the sealing element 4.

[0230] Fig. 10 illustrates a first position of the sealing element 4, in which the internal thread 42 begins to engage with the external thread 32 of the neck 30 of the container 2, 3.

[0231] Starting from the position illustrated in [Fig.10], a torque is applied for example to the sealing element 4 to rotate it relative to the neck 30 of the container 2, 3 in a screwing direction SV.

[0232] During this screwing movement of the sealing element 4 onto the neck 30 of the bottle 2, 3 in the screwing direction SV, the front edge 43 of the sealing element 4, being opposite in the axial direction of the tab 310, comes into contact with the second end 312 of each tab 310 and exerts on them an axial force towards the bottom 20 of the container 2, 3 tending to elastically flex the tabs 310 in this same direction, as illustrated in figures 11 and 12. During this screwing movement of the sealing element 4 onto the neck 30 of the container 2, 3 in the screwing direction SV, the free ends 312 of the tabs slide against the front edge 43 of the sealing element 4 in the circumferential direction.

[0233] By continuing this screwing movement of the sealing element 4 onto the neck 30 of the container 2, 3 in the screwing direction SV, the notches 44 defining the anti-unscrewing stop surfaces 440 are brought progressively into alignment in the circumferential direction of the free end 312 of the tabs 310, presenting an anti-unscrewing stop surface 313, as seen in [Fig.13].

[0234] When the sealing element 4 approaches the end of the screwing stroke on the neck 30 of the container 2, 3, for example when stop surfaces 314, 450 provided respectively on the shoulder 31 of the container 2, 3 and on the sealing element 4 are separated from each other in the circumferential direction by an angle between 0.5° and 10°, the free end 312 of each tab 310 is brought into contact with the respective notch 44 and the contact of the free end 312 of each tab 310 with the front edge 43 of the sealing element 4 is broken.The tabs 310 then move into a locking position, by elastic return in the axial direction, so that the anti-unscrewing stop surface 313 provided on the free end 312 of each tab 310 is opposite in the circumferential direction the complementary anti-unscrewing stop surface 440 provided on the sealing element 4, in order to block the rotation of the sealing element 4 relative to the neck 30 of the container 2, 3 in an unscrewing direction SD when the element. the sealing action reaches the end of the screwing stroke on the neck of the bottle, as illustrated in figures 9 and 13.

[0235] For the aforementioned purposes, a person skilled in the art will be able to adapt the design and in particular dimension and position, in particular in the circumferential direction, the external thread 32 of the neck 30 of container 2, 3, the internal thread 42 of the fixing skirt 41 of the sealing element 4, the stop surfaces 314, 450 defining the end of the screwing stroke of the sealing element 4 on the neck 30 of container 2, 3, as well as the anti-unscrewing stop surfaces 313, 440 provided on the shoulder 31 of container 2, 3 and on the sealing element 4.

[0236] The refill-forming device 10 according to the invention is then in the configuration in which it will be marketed, with the sealing element 4 in the position of sealing the container 2, 3, and with the tabs 310 in the locking position prohibiting the rotation of the sealing element 4 relative to the neck 30 of the container 2, 3 in an unscrewing direction SD, so as to prevent a user from using the refill-forming device 10 alone.

[0237] Thus, it is only when the sealing element 4 is associated with a covering and gripping cover 8, 9 that the tabs 310 are placed in the unlocking position and that the unscrewing of the sealing element 4 from the neck 30 of the container 2, 3 is permitted.

[0238] In the embodiment illustrated in figures 2 to 13, the refill container 10 is in the form of a bottle, typically intended to contain the cosmetic product and whose closure element 4 is associated with a stem 5 whose end is provided with an application member 6.

[0239] The embodiment illustrated in [Fig. 14], in which the same elements bear the same references, differs from the previous embodiment only in that the sealing element 4 is devoid of an application member 6 and forms a simple sealing plug of the opening O of the device forming the refill 10.

[0240] The embodiment illustrated in Figures 15 to 17, in which the same elements bear the same reference numerals, differs from the embodiment illustrated in Figures 1 to 13 only in the general shape of the packaging assembly 1, in which the refill-forming device 10 has a hemispherical base 20 and the casing assembly 100 has a cylindrical shape, and in that the casing assembly 100 does not comprise a separate casing and mounting bracket, but forms a single piece. The sealing element 4 here forms a simple cylindrical cap.

[0241] As illustrated, the rechargeable assembly 1 further comprises a cover ring 200 intended to radially surround the axial retaining ring 105 so as to be flush with both the outer wall of the obturator member 4 and the outer wall of the assembly 100 dressing.

[0242] As illustrated in detail in figures 15 to 17, the casing assembly 100 is provided with a closed lower end forming a base 110 and an open upper end 103, opposite the lower end 110, forming a neck and provided with an opening 02 allowing access to an internal space E for receiving the device forming a refill 10.

[0243] The casing assembly 100 includes a peripheral side wall 121 extending between the bottom 110 and the neck 103 and connected to the latter via a radial collar 122 forming a shoulder 104.

[0244] The base 20 of the device forming the refill 10 is, here, axially spaced from the base 110 of the casing assembly 100.

[0245] As seen in detail in [Fig.16], the peripheral wall 121 of the neck 103 is discontinuous and comprises a plurality of flexible legs 123 extending axially from the radial collar 122 and spaced apart from each other in the circumferential direction.

[0246] In the example illustrated in [Fig. 16], the peripheral wall 121 of the neck 103 comprises two groups of three flexible legs 123a, 123b, the legs 123 of each group 123a, 123b being spaced by a first circumferential gap J1 and the two groups being spaced from each other by a second circumferential gap J2. The first circumferential gap J1 is smaller than the second circumferential gap J2.

[0247] As illustrated, each flexible leg of each leg group includes an external snap-in element 124, here a radially outward projecting bead, defining with the radial collar 122, a snap-in groove 125 intended to cooperate with a radial rib 151 provided on an axial retaining ring 105.

[0248] As illustrated, two of the flexible legs of each leg group include, at their upper free end, an internal snap-fit ​​element 126, here an internal bead projecting radially inwards, intended to fit into the rear of the complementary external snap-fit ​​bead or rib 37 provided on the added element 3, in particular on the fixing skirt 36.

[0249] As illustrated in Figures 15 and 16 and in no way limiting, the peripheral wall 121 of the casing assembly 100 has two circumferential through-opening windows or openings 127, allowing the user to view part of the container of the device 10 forming a refill through the casing assembly 100 when it is received within it.

[0250] The two circumferential windows 127 are, here, located radially opposite each other.

[0251] Alternatively, it could be envisaged that a single circumferential window 127 extending over an angular range between 10° and 90°, for example equal to 45°.

[0252] The present invention further proposes a method for recharging a refillable assembly 1 of cosmetic product packaging according to one or the other of the embodiments.

[0253] In this refilling process, the user has a refillable cosmetic product packaging assembly 1 whose refillable device 10 forming a refill is worn out, i.e. substantially emptied of its contents, and must be replaced by a new refillable device 10'.

[0254] Thus, in a first phase of this reloading process, visible in [Fig.18A], the user removes, detaches the cover for dressing and gripping 8, 9 from the sealing element belonging to the device 10 forming the used refill.

[0255] The removal of the cover and gripping hood 8, 9 from the sealing element 4 is carried out by relative separation of these two elements in the axial direction causing the groove 94 carried by the cover and gripping hood 8, 9 to come out of the groove 44 provided on the sealing element 4.

[0256] However, the prior step of removing the cover and gripping 8, 9 is not necessary to be able to place the ring 105 in the unlocking position of the device 10 forming a refill.

[0257] The user then rotates the axial retaining ring 105 in a first direction of rotation RI, as seen in [Fig. 18B], until the radial projections 152 of said ring 105 are angularly offset from the flexible tabs 123 provided with internal snap-fit ​​elements 126 of the mounting bracket 102.

[0258] The user then takes hold of the used refill device 10 and applies an axial extraction force outwards in order to cause the flexible tabs 123 equipped with internal snap-in elements 126 of the mounting bracket 102 to spread apart under the effect of the corresponding complementary external snap-in elements 37 provided on the container 2, 3, in order to manually extract the container 2, 3 of the used refill device 10 from the housing assembly 100, as seen in [Fig.18C].

[0259] The user then takes a new refill device 10', the internal volume V of which is filled with product, and inserts it into the space E of the housing assembly 100, visible on [Fig. 18D], until the axial retaining device formed by the cooperation between the internal snap-in elements 126 of the mounting bracket 102 and corresponding complementary external snap-in elements 37 provided on the container 2, 3 of the new refill device 10' is clicked into place.

[0260] The user rotates the axial retaining ring 105 in a second direction of rotation R2, opposite to the first direction of rotation RI, as shown in [Fig. 18E], until the radial projections 152 of said ring 105 are located behind the flexible legs 123 provided with internal snap-in elements 126 of the mounting bracket 102 and thus lock the axial retaining device in the snap-in position.

[0261] The user positions and fixes the cover for dressing and gripping 8, 9 on the new refilling device 10' which was fitted to the used refilling device 10.

[0262] However, this step of putting the cover back in place and gripping 8, 9 after placing the ring 105 in the locking position of the device 10' forming new refill is not necessarily required.

[0263] In all embodiments, the cover and grip 8, 9, and the cover assembly 100 are, for example, made of plastic, in particular a thermoplastic polymer, such as polypropylene (PP), polyethylene (PET), or polybutylene terephthalate (PBT), or even a recycled plastic. The cover and grip 8, 9, and the cover assembly 100 are preferably made of the same plastic material.

[0264] For example, the main body 2 and the added element 3 of the refillable container are made of plastic, advantageously of the same material.

[0265] According to another variant, the main body 2 of the refillable container is made of drawn glass.

[0266] The axial retaining ring 105 can be made of plastic material, in particular thermoplastic polymer, such as polypropylene (PP) or of metallic material, in particular aluminium.

[0267] In all embodiments, the axial retaining ring 105 is not removable and remains axially attached to the casing assembly 100 even when the container 2, 3 is removed from the refilling device 10.

[0268] Thanks to the various provisions of the invention, the Applicant Company is able to offer its customers a cosmetic product packaging set 1 comprising a refill-forming device with improved axial retention functionality and a minimalist structure, thus reducing the environmental impact resulting from both the manufacture of this refillable set, through in particular a limitation of the raw materials used, its packaging and its transport, through in particular a limitation of the mass of the refill-forming device, or its end-of-life treatment.

[0269] Furthermore, with a packaging assembly according to the invention, the Applicant Company is also able to preserve and guarantee an optimal user experience by locking or unlocking the axial retention of the container forming the refill on the casing assembly.
