Description

Title of the invention: Assembly for packaging and distributing a product, particularly a cosmetic product.

[0001] The present invention relates to the field of packaging and distribution of a product, in particular a cosmetic product.

[0002] For the purposes of the present invention, the term “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 relating to cosmetic products.

[0003] More particularly, the present invention relates to the field of assemblies for packaging and dispensing a product, in particular a cosmetic product, comprising a bottle intended to contain the product and provided with a flow orifice, a reducer mounted on said bottle and comprising a dispensing orifice with a diameter smaller than the diameter of the flow orifice and a cover intended to close the dispensing orifice of the reducer in a closed position.

[0004] The proposal of eco-responsible, environmentally friendly solutions, the design and development of which take environmental issues into account, is becoming a major concern to help meet global challenges.

[0005] It is therefore essential to design products that reduce the quantity 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.

[0006] In this context, it is important to develop packaging that generates less waste, in particular optimized for the quantity of products transported, in particular by redesigning and / or resizing them in order to reduce the volume and weight of the quantity of packaging.

[0007] The objective is to offer reusable eco-responsible containers, particularly those that can be refilled at home or in stores, in order to reduce the carbon footprint of packaging devices.

[0008] The present invention is part of this approach to developing refillable packaging for the field of cosmetic products, and in particular care products such as shampoo or washing gel.

[0009] Conventionally, whether in the field of packaging cosmetic products or other products, the reducer is generally clipped onto the container and cannot be detached from said container without damaging it. Indeed, it is possible, using a utensil, such as a screwdriver, corkscrew or other object, to extract, albeit with difficulty, the reducer from the container. However, such extraction damages the reducer which cannot be repositioned while ensuring a good seal with the container.

[0010] Reference may be made to document JP 2002 - 166958A which proposes a reducer mounted by snap-fastening onto the neck of a container and comprising a system to prevent the reducer from being detached from the container.

[0011] Such a solution does not allow the reducer to be separated from the container without damaging it. Furthermore, the reducer and the container described in this document have a plurality of shapes, which complicates the manufacture of these elements and increases the quantity of material used.

[0012] The present invention therefore aims to overcome the above drawbacks and to improve product packaging and dispensing assemblies comprising a container and a reducer of the diameter of the dispensing orifice mounted on the container in order to allow the said reducer to be detached without damaging it.

[0013] Another objective of the invention is to simplify the manufacture of the product packaging and distribution assembly.

[0014] The subject of the invention is a packaging and distribution assembly for a product, in particular a cosmetic product, extending axially along an elevation axis and comprising: - a tank or container comprising a neck comprising an opening and delimiting an internal volume intended to receive the product, - a reducer removably attached to the container and comprising a dispensing orifice in fluid communication with the internal volume of the container in an assembled position, the dispensing orifice having an internal diameter less than the internal diameter of the opening of the container, and - a hood or cover removably attached to said container and configured to close the distribution orifice of the reducer in the assembled position.

[0015] The neck comprises a stepped outer cylindrical surface comprising: - a first external surface comprising an external thread intended to cooperate with an internal tapping or thread provided on the cover, - a second outer surface having an outer diameter less than the outer diameter of the first outer surface, and - a disengagement relief connecting the first outer surface and the second outer surface and configured to cooperate with a complementary relief carried by the reducer and to move axially along the elevation axis the reducer away from the container during a relative rotation, for example 90°, between said reducer and the container.

[0016] The complementary relief of the reducer is in conformity in shape with the relief of disengagement carried by the neck of the container.

[0017] In other words, the neck of the container is radially delimited by a stepped outer cylindrical surface and the second outer surface is offset radially inwardly relative to the first outer surface.

[0018] By "product" is meant a liquid, semi-liquid, or viscous product intended to flow out of a reservoir under the effect of gravity. The product may be, in a non-limiting manner, a cosmetic product, such as for example a hygiene product or a care product.

[0019] The reducer thus forms a member for reducing the flow diameter of the product contained in the container.

[0020] The removable attachment between the reducer and the container and the cooperation between the disengagement relief on the neck of the container and the complementary relief on the reducer makes it possible to easily detach the reducer from the container and thus to refill the container when it is empty.

[0021] Advantageously, the disengagement relief provided on the neck of the container is located axially between the external thread provided on the neck of the container, in particular the first external surface, and an open distal end of the container.

[0022] In other words, the external thread provided on the neck of the container is located axially below the disengagement relief provided on the neck of the container in the direction of the elevation axis.

[0023] The disengagement relief allows the reducer to be disengaged from the container when said reducer is rotated 90° relative to said container.

[0024] Advantageously, the disengagement relief extends over the circumference of the stepped cylindrical outer surface of the neck of the container, in particular near the distal end of the neck.

[0025] The disengagement relief preferably comprises circumferentially at least one pair of ramps and at least one rounded junction.

[0026] According to a preferred embodiment, the disengagement relief comprises at least two pairs of ramps connected to each other by a rounded junction.

[0027] Preferably, the two rounded junctions of the disengagement relief are circumferentially offset at 180° from each other and are located at the same height on the neck of the container.

[0028] “Height” means the direction in the direction of the elevation axis of an element of the assembly.

[0029] Alternatively, a number greater than two of rounded junctions and pairs of ramps could be provided, for example three rounded junctions circumferentially offset at 120° from each other.

[0030] Generally speaking, the number of rounded junctions corresponds to the number of pairs of ramps.

[0031] The disengagement relief is in the form of a recess in the material of the stepped cylindrical outer surface at the distal end of the neck of the container.

[0032] Advantageously, each pair of ramps of the disengagement relief provided on the neck of the container comprises a first ramp extending circumferentially from the first rounded junction at a slope inclined relative to a longitudinal axis towards the distal end of the neck and a second ramp extending circumferentially from the first ramp at a slope inclined relative to the longitudinal axis towards the second rounded junction.

[0033] In other words, the first ramp and the second ramp of the disengagement relief extend along two opposite slopes, the apex of which is located at the point of contact between said ramps.

[0034] Advantageously, the reducer comprises an internal skirt intended to be inserted into the neck of the container in the assembled position and an external skirt radially surrounding said internal skirt and intended to radially surround the neck of the container in the assembled position, said external skirt comprising a lower end comprising the complementary relief intended to cooperate with the disengagement relief provided on the stepped external surface of the neck in the assembled position of the reducer on the container.

[0035] The internal skirt is, for example, secured to the neck of the container by a tight assembly.

[0036] For example, the complementary relief provided on the reducer extends around the circumference of the lower end of the outer skirt and circumferentially comprises at least one pair of ramps and at least one rounded junction, said pair of ramps of the complementary relief being intended to cooperate with the pair of ramps of the relief for disengaging the container in the assembled position.

[0037] According to a preferred embodiment, the complementary relief comprises at least two pairs of ramps connected to each other by a rounded junction, said pairs of ramps of the complementary relief being intended to cooperate with the pairs of ramps of the relief for disengaging the container in the assembled position.

[0038] The two rounded junctions of the complementary relief of the reducer are preferably circumferentially offset at 180° from each other and are located at the same height on the external skirt.

[0039] Alternatively, a number greater than two of rounded junctions and pairs of ramps of the complementary relief could be provided, for example three rounded junctions circumferentially offset at 120° from each other.

[0040] Generally, the number of rounded junctions corresponds to the number of pairs of ramps.

[0041] Advantageously, each pair of ramps of the complementary relief of the reducer comprises a first ramp extending circumferentially from the first rounded junction along a slope inclined relative to the longitudinal axis towards the upper end of the external skirt and a second ramp extending circumferentially from the first ramp along a slope inclined relative to the longitudinal axis towards the second rounded junction.

[0042] In other words, the first ramp and the second ramp of the complementary relief of the reducer extend along two opposite slopes, the apex of which is located at the point of contact between said ramps.

[0043] According to one embodiment, the internal skirt of the reducer comprises on its external surface, a snap-fastening element cooperating with a complementary snap-fastening element provided on the internal surface of the neck of the container.

[0044] This results in improved axial strength of the reducer relative to the container and avoids any unexpected detachment.

[0045] For example, the snap-fastening element carried by the internal skirt of the reducer is an annular bead extending in radial projection from the external surface of the internal skirt towards the outside and the complementary snap-fastening element carried by the neck of the container is an annular groove.

[0046] Alternatively, a structural inversion could be provided in which the latching element carried by the internal skirt of the reducer is an annular groove and in which the complementary latching element carried by the neck of the container is an annular bead extending in radial projection from the internal surface of the neck of the container towards the inside.

[0047] According to another embodiment, the external skirt of the reducer comprises on its internal surface, at the end of each rounded junction of the complementary relief, at least one non-annular snap-fastening element cooperating with a corresponding non-annular complementary snap-fastening element provided on the second external surface of the neck of the container.

[0048] This results in improved axial strength of the reducer relative to the container and avoids any unexpected detachment.

[0049] For example, each complementary snap-in element provided on the second outer surface of the container neck is located axially between an annular junction and the distal end of the container and circumferentially between a first ramp of a ramp and a second ramp of an adjacent ramp.

[0050] According to an exemplary embodiment, each snap-fastening element of the reducer is a radial, non-annular projection extending radially from the inner surface towards the inside and each complementary snap-fastening element of the container is a non-annular notch extending over a portion of the circumference of the second outer surface of the neck of the container, circumferentially between two ramps of two pairs of ramps and radially.

[0051] Alternatively, a structural inversion could be provided in which the internal surface of the external skirt of the reducer comprises at the end of each rounded junction of the complementary relief, a snap-fastening element, in the form of a non-annular notch, cooperating with a complementary snap-fastening element in the form of a non-annular radial projection extending radially from the second external surface of the neck of the container towards the outside.

[0052] For example, each snap-on projection extends circumferentially over a portion of the circumference of the second outer surface of the container neck, between two of two pairs of ramps

[0053] For example, the reducer comprises an upper wall provided with the distribution orifice, the inner skirt and the outer skirt each extending from said upper wall.

[0054] For example, the outer skirt is delimited radially by an inner surface and an outer surface and axially by the open lower end and an upper end connected to the upper wall.

[0055] For example, the dispensing orifice opens onto a boss which projects axially outwards from the upper wall.

[0056] Alternatively, it could be provided that the distribution orifice opens onto a flat or substantially flat upper wall.

[0057] In the assembled position, the upper wall is in axial contact with the upper end of the container.

[0058] For example, the outer skirt has a smaller axial dimension than the inner skirt.

[0059] Preferably, the inner skirt comprises a sealing portion comprising an outer surface in radial contact with an inner surface of the neck of the container in the assembled position.

[0060] For example, and in a non-limiting manner, the internal skirt comprises an insertion portion extending axially from the sealing portion on the side opposite the upper wall and having an outside diameter smaller than the outside diameter of the sealing portion in order to facilitate the insertion of the reducer into the opening of the container. Alternatively, the internal skirt could comprise only the sealing portion.

[0061] For example, wherein the outer skirt comprises an outer surface comprising a plurality of reliefs, for example axial ribs, circumferentially distributed around the periphery of said outer surface.

[0062] Such reliefs allow the user to easily grip the reducer in view of its positioning in the container and of its unscrewing relative to the container.

[0063] For example, the container comprises a main body extending axially along the elevation axis between a closed lower end forming a bottom and an open distal upper end, opposite the lower end, forming the neck provided with the opening allowing access to the internal volume for receiving the product, said neck, in particular the first external surface, being connected to the body of the container by means of an annular collar, said neck being connected to said annular collar by a shoulder.

[0064] By "shoulder" is meant any surface substantially normal to the elevation axis of a cylindrical part, here the elevation axis of the container, resulting from a sudden variation in diameter.

[0065] For example, the annular flange is connected to the body by a first junction so as to be offset radially inwardly relative to said body and the neck is connected to the annular flange by a second junction, such as the shoulder, so as to be offset radially inwardly relative to said flange.

[0066] Alternatively, it could be provided that the neck, in particular the first external surface, is directly connected to the body of the container by a shoulder, without an intermediate annular collar.

[0067] By “junction” is meant a portion connecting two parts together.

[0068] The first junction has, for example, an inclined slope. Alternatively, it could be provided that the first junction is a shoulder.

[0069] For example, the external thread carried by the neck of the container, in particular by the first external surface, comprises a single thread comprising a distal end and a proximal end and the neck of the container comprises on its first external surface at least one stop for the end of screwing the cap onto the container.

[0070] The distal end is the end of the thread of the external thread closest to the distal end of the neck and the proximal end is the end of the thread of the external thread closest to the second shoulder between the neck and the annular flange.

[0071] The thread forms a helix about the elevation axis on the first outer surface of the neck between the distal end of the neck and a proximal end of the neck connected to the second shoulder.

[0072] The external thread has a screwing direction going from the distal end towards the proximal end of the neck.

[0073] Alternatively, the neck of the container comprises at least one end-of-screwing stop extending radially from the outer surface of the neck towards the outside.

[0074] According to one embodiment, the end of screwing stop comprises a first projecting element extending axially from the shoulder between the neck, in particular the first outer surface, and the annular collar towards the distal end of the neck and a second projecting element extending axially from the proximal end of the thread of the external thread to the first projecting element.

[0075] For example, the first projecting element comprises a stop surface, for example vertical, and forms a stop or notch for the end of screwing for the cover.

[0076] For example, the second projecting element is in the form of an axial rib extending axially along the elevation axis from the first projecting element to the proximal end of the thread of the external thread. The axial ribs form a circumferential stop for each proximal end of the threads of the tapping of the cover.

[0077] For example, the body of the container has a non-circular cross-section and the neck of the container has a circular cross-section.

[0078] Alternatively, the body of the container could have a circular section or any other shape.

[0079] According to one embodiment, the cover comprises an external wall delimited by an end and a radial upper wall and a stepped internal wall in shape matching the neck of the container delimited by an end wall provided with a sealing lip intended to come into contact with the radial upper wall of the reducer in the assembled position.Said stepped internal wall comprises a first cylindrical skirt radially surrounding the first junction connecting the neck to the body of the container, a second cylindrical skirt radially surrounding the first external surface of the container neck and comprising on its internal surface the first internal thread cooperating with the first external thread carried by said neck, a third cylindrical skirt radially surrounding the second external surface of the neck of the container and the reducer in the assembled position, the third cylindrical skirt having an external diameter smaller than the internal diameter of the second cylindrical skirt of the internal wall of the cap.

[0080] Thus, a particularly axially compact packaging and distribution assembly is obtained.

[0081] For example, the outer wall of the hood has a non-circular cross-section and the inner wall of the hood has a circular cross-section. Alternatively, the outer wall of the hood could have a circular cross-section or any other shape.

[0082] Alternatively, the cover could have a completely different shape and comprise a cylindrical wall delimited by an open end and a radial upper wall intended to come into axial contact, directly or via the boss, with the radial upper wall of the reducer in the assembled position, the cylindrical wall comprising on its internal surface the first internal thread cooperating with the first external thread carried by the neck of the container. The cylindrical wall of the cover radially surrounds the entire reducer in the assembled position. Thus, a set of condi- particularly axially compact operation and distribution.

[0083] Alternatively, it could be provided that the hood is made of two pieces integral in rotation with each other.

[0084] The hood can be made in a single piece or in several pieces integral with each other.

[0085] For example, the container and the cover can be made of any plastic material using techniques such as injection stretch blow molding (ISBM), injection blow molding (IBM), extrusion molding (EBM), injection molding (IM), in particular of thermoplastic polymer, such as for example polypropylene (PP), polyethylene (PE), or polybutylene terephthalate (PBT), or even of a recycled plastic material, known by the abbreviation PCR or Post Consumer Recycling in Anglo-Saxon terms.

[0086] The reducer is preferably made in a single piece, for example by injection molding a plastic material, for example a thermoplastic polymer, such as for example a polyolefin material of the polyethylene and / or polypropylene (PE / PP) type or even a recycled plastic material “PCR” or high density polyethylene (HDPE).

[0100] In the remainder of the description, we consider an orthonormal base X, Y, Z, with Z corresponding to an elevation or elongation axis representing the vertical direction in which we find:

[0101] - a longitudinal axis X, horizontal and extending from left to right on [Fig.2];

[0102] - a transverse axis Y, horizontal, perpendicular to the longitudinal axis X and extending from front to back on [Fig.2]; and

[0103] - a vertical axis Z, orthogonal to the longitudinal axes X and transverse Y and extending from bottom to top on [Fig.2].

[0104] The expressions “upper” and “lower” refer to the upper part and the lower part of the figures.

[0105] The terms "interior" or "internal" and "exterior" or "external" refer to the interior of the product packaging and dispensing assembly, the internal or interior portions being closer to the elevation axis Z-Z' than the external or exterior portions.

[0106] In [Fig.l] is shown a unit 1 for packaging and distributing a product, in particular a cosmetic product.

[0107] By "product" is meant a liquid, semi-liquid, or viscous product intended to flow out of a reservoir under the effect of gravity. The product may be, in a non-limiting manner, a cosmetic product, such as for example a product hygiene or care product.

[0108] The assembly 1 for packaging and dispensing a product comprises a reservoir or container 10, a reducer 20 removably attached to the container 10 and a hood or cover 30 removably attached to the container 10.

[0109] The container 10 delimits an internal volume V containing the product.

[0110] In the embodiment illustrated in the figures, the container 10 comprises a main body 11 extending axially along the elevation axis Z-Z' assumed to be vertical in the figures and provided with a closed lower end forming a bottom 12 and an open upper end 13, opposite the lower end 12, forming a neck 14 provided with an opening O allowing access to the internal volume V for receiving the product.

[0111] As illustrated, the body 11 of the container 10 here has a non-circular cross-section and the neck 14 has a circular cross-section. Alternatively, the body 11 of the container 10 could have a circular cross-section or any other shape.

[0112] The non-circular cross-section of the body 11 of the container 10 here has an ovoid shape defined by a major axis Al and a minor axis A2 lower, for example, by at least 20% compared to the major axis AL. The axes Al, A2 are visible in [Fig.2A].

[0113] The neck 14 is connected to the body 11 of the container 10 by an annular collar 15.

[0114] The annular collar 15 is connected to the body 11 by a first junction 11a in order to be offset radially inwards relative to said body 11 and the neck 14 is connected to the annular collar 15 by a second junction 15a in order to be offset radially inwards relative to said collar 15.

[0115] Alternatively, it could be provided that the neck 14 is directly connected to the body 11 of the container 10 by a shoulder, without an intermediate annular collar.

[0116] By “junction” is meant a portion connecting two parts together.

[0117] The first junction 11a here has an inclined slope. Alternatively, it could be provided that the first junction 11a is a shoulder.

[0118] The second junction 15a is here a shoulder.

[0119] By “shoulder” is meant any surface substantially normal to the elevation axis of a cylindrical part, here the elevation axis Z-Z' of the container 10, resulting from a sudden variation in diameter.

[0120] The neck 14 extends around the elevation axis Z-Z' and is delimited radially by a stepped outer cylindrical surface 14a and an inner cylindrical surface 14b.

[0121] The stepped outer cylindrical surface 14a comprises a first outer surface 14c comprising an external thread 16 intended to cooperate with an internal tapping or thread 34 provided on the cover 30.

[0122] The external thread 16 here comprises a single thread comprising a distal end 16a and a proximal end 16b, visible in [Fig.4].

[0123] The distal end 16a is the end of the thread of the external thread 16 closest to the distal end 13 of the neck 14 and the proximal end 16b is the end of the thread of the external thread 16 closest to the second shoulder 15a between the neck 14 and the annular collar 15.

[0124] The thread 16 forms a helix around the elevation axis Z-Z' on the first outer surface 14c of the neck 14 between the distal end 13 of the neck 14 and a proximal end of the neck 14 connected to the second shoulder 15a.

[0125] The external thread 16 has a screwing direction going from the distal end 13 towards the proximal end of the neck 14.

[0126] As illustrated, the neck 14 of the container 10 further comprises a first pair 17 of two projecting elements 17a, 17b extending radially from the first outer surface 14c of the neck 14 outwardly.

[0127] The first pair 17 of projecting elements forms a stop for the end of screwing the cover 30 onto the container 10.

[0128] The first pair 17 comprises a first projecting element 17a extending axially from the second shoulder 15a towards the distal end 13 of the neck 14 and a second projecting element 17b extending axially from the proximal end 16b of the thread of the external thread 16 to the first projecting element 17a.

[0129] The first projecting element 17a comprises a stop surface (not referenced), here vertical, and forms a stop or end-of-screwing notch for the cover 30.

[0130] The second projecting element 17b is in the form of an axial rib extending axially along the elevation axis Z-Z' from the first projecting element 17a to the proximal end 16b of the thread of the external thread 16.

[0131] The axial rib 17b forms a circumferential stop for the proximal end of the thread of the tapping 36b of the cover 30.

[0132] As illustrated, the neck 14 of the container 10 further comprises a second pair 17c of projecting elements, visible in [Fig. 2], extending radially from the first outer surface 14c of the neck 14 outwards. The second pair 17c is located at 180° from the first pair 17 on said surface 14c of the neck 14. Said second pair 17c forms an axial support for the cover 30 in the position in which the container 10 is closed by the cover 30.

[0133] The stepped cylindrical outer surface 14a of the neck 14 comprises a second outer surface 14d and a disengagement relief 18 axially connecting the first outer surface 14c and the second outer surface 14d.

[0134] The first outer surface 14c has an outer diameter greater than the second outer surface 14d of the cylindrical outer surface 14a of the neck 14 of the container 10.

[0135] In other words, the second outer surface 14d is radially offset towards the inside relative to the first outer surface 14c of the neck 14.

[0136] The disengagement relief 18 makes it possible to disengage the reducer 20 relative to the container 10 when said reducer 20 is rotated at 90° relative to said container 10.

[0137] The disengagement relief 18 is intended to cooperate with a complementary relief 27 provided on a lower end 26a of a mounting skirt 25 of the reducer 20.

[0138] The disengagement relief 18 extends around the circumference of the cylindrical outer surface 14a of the neck 14 of the container 10, close to the distal end 13 of the neck 14.

[0139] The disengagement relief 18 here comprises two pairs 19 of ramps 19a, 19b connected to each other by a rounded junction 18a, 18b.

[0140] The two rounded junctions 18a, 18b are circumferentially offset at 180° from each other and are located at the same height on the neck 14 of the container 10.

[0141] “Height” means the direction in the direction of the elevation axis Z-Z' of the container 10.

[0142] Alternatively, at least one rounded junction and at least one pair of ramps could be provided, or a number of rounded junctions greater than two and a number of pairs of ramps greater than two, for example three rounded junctions circumferentially offset at 120° from each other.

[0143] Generally, the number of rounded junctions corresponds to the number of pairs of ramps.

[0144] The disengagement relief 18 is in the form of a material recess of the cylindrical outer surface 14a at the distal end 13 of the neck 14.

[0145] Each pair 19 of ramps comprises a first ramp 19a extending circumferentially from the first rounded junction 18a at a slope inclined relative to the longitudinal axis X towards the distal end 13 of the neck 14 and a second ramp 19b extending circumferentially from the first ramp 19a at a slope inclined relative to the longitudinal axis X towards the second rounded junction 18b.

[0146] In other words, the first ramp 19a and the second ramp 19b extend along two opposite slopes, the apex of which is located at the point of contact between said ramps 19a, 19b.

[0147] As illustrated in the figures, the reducer 20 extends along the elevation axis Z-Z'.

[0148] The reducer 20 comprises an internal skirt 21 intended to be inserted into the neck 14 of the container 10 and delimited by an open lower end 22 and an upper wall 23 provided with a distribution orifice 24 for the passage of the product contained in the container 10.

[0149] The internal skirt 21 comprises a sealing portion 21a whose external surface 21b is in radial contact with the internal surface 14b of the neck 14 of the container 10 in the assembled position visible in FIG. 3.

[0150] As illustrated, and in a non-limiting manner, the internal skirt 21 comprises an insertion portion 21c extending axially from the sealing portion 21a on the side opposite the upper wall 23 and having an outside diameter smaller than the outside diameter of the sealing portion 21a in order to facilitate the insertion of the reducer 20 into the opening O of the container 10. Alternatively, the internal skirt 21 could comprise only the sealing portion 21a.

[0151] In the assembled position, the upper wall 23 is in axial contact with the upper end 13 of the container 10.

[0152] As illustrated and in a non-limiting manner, the distribution orifice 24 opens onto a boss 23a which extends in axial projection outwards from the radial upper wall 23. Alternatively, it could be provided that the distribution orifice 24 opens onto a flat or substantially flat upper wall 23.

[0153] The diameter of the distribution orifice 24 of the reducer 20 is less than the diameter of the opening O of the container 10.

[0154] The reducer 20 thus forms a member for reducing the flow diameter of the product contained in the container 10.

[0155] As illustrated in Figures 3A and 3B, the reducer 20 comprises an outer skirt 25 extending axially from a lateral end 23b of the upper wall 23 downwards and radially surrounding the inner skirt 21.

[0156] The external skirt 25 here has a smaller axial dimension than the internal skirt 21.

[0157] The external skirt 25 is delimited radially by an internal surface 25a and an external surface 25b and axially by an open lower end 26a and an upper end 26b connected to the upper wall 23.

[0158] The lower end 26a of the external skirt 25 comprises a complementary relief 27 intended to cooperate with the disengagement relief 18 provided on the external surface 14a of the neck 14 in the assembled position of the reducer 20 on the container 10.

[0159] The complementary relief 27 extends over the circumference of the lower end 26a of the external skirt 25 and here comprises two pairs 28 of ramps 28a, 28b connected to each other by a rounded junction 29a, 29b.

[0160] The two rounded junctions 29a, 29b are circumferentially offset at 180° from each other and are located at the same height on the external skirt 25.

[0161] Alternatively, a different number of pairs 28 of ramps 28a, 28b and rounded junctions 29a, 29b could be provided.

[0162] The number of pairs 28 of ramps 28a, 28b of the complementary relief 27 is dependent on the number of pairs 19 of ramps 29a, 29b of the disengagement relief 18.

[0163] Each pair 28 of ramps comprises a first ramp 28a extending circumferentially from the first rounded junction 29a along a slope inclined relative to the longitudinal axis X towards the upper end 26b of the external skirt 25 and a second ramp 28b extending circumferentially from the first ramp 28a along a slope inclined relative to the longitudinal axis X towards the second rounded junction 29b.

[0164] In other words, the first ramp 28a and the second ramp 28b extend along two opposite slopes, the apex of which is located at the point of contact between said ramps 28a, 28b.

[0165] The complementary relief 27 of the reducer 20 is in conformity in shape with the disengagement relief 18 of the neck 14 of the container 10.

[0166] The external skirt 25 here forms a mounting skirt for the reducer 20 on the container 10.

[0167] As illustrated and in a non-limiting manner, the external skirt 25 comprises on its external surface 25b, a plurality of axial ribs 25c circumferentially distributed around the periphery of said external surface 25b. Such axial ribs 25c allow the user to easily grip the reducer 20 for the purpose of positioning it in the container 10 and unscrewing it relative to the container 10.

[0168] Alternatively, other forms of relief could be provided on the external surface 25b of the external skirt 25 of the reducer 20.

[0169] When the reducer 20 is rotated 90° relative to the container 10, the lower end 26a of the mounting skirt 25 of the reducer 20 slides on the disengagement relief 18 provided on the neck 14 of the container 10 until each rounded junction 29a, 29b of the complementary relief 28 is axially opposite a corresponding pair 19 of ramps 19a, 19b, generating the axial displacement along the elevation axis Z-Z' of the reducer 20 relative to the container 10 upwards, as visible in [Fig.7].

[0170] The user can then grasp said reducer 20 and detach it from the container 10 by an axial force upwards according to the arrow F, visible in [Fig.8].

[0171] The reducer 20 is placed on the container 10 solely by an axial force on the reducer 20 towards the container 10 during which the internal skirt 21 of the reducer 20 comes into tight contact with the internal surface 14b of the neck 14 of the container 10.

[0172] The detachment of the reducer 20 from the container 10 is carried out exclusively by a rotational movement of the reducer 20 from the container 10 generating, as described above, an axial upward movement of said reducer 20 from the container 10.

[0173] After detaching the reducer 20 from the container 10, the container 10 can be filled and reused when its internal volume V is empty.

[0174] The cover 30 is configured to close the distribution orifice 24 of the reducer 20 in the assembled position.

[0175] As illustrated, and in no way limiting, the cover 30 is understood along an elevation axis assumed to be vertical in the figures and comprises an external wall 31, here of non-circular section, delimited by a closed lower end 32 and a radial upper wall 33 intended to come above the radial upper wall 23 of the reducer 20 in the assembled position.

[0176] The cover 30 is here made of two pieces secured to each other.

[0177] Alternatively, it could be provided that the cover 30 is made in a single piece.

[0178] Alternatively, a cylindrical hood could also be provided.

[0179] The hood further comprises an inner wall 34 connected to the lower wall 32.

[0180] The internal wall 34 of the cover 30 is in conformity in shape with the neck 14 of the container 10.

[0181] The internal wall 34 of the cover 30 successively comprises, along the extension axis Z-Z', a first cylindrical skirt 35 radially surrounding the annular collar 16 of the container 10, a second cylindrical skirt 36 radially surrounding the first external surface 14c of the neck 14 and a third cylindrical skirt 37 surrounding the second external surface 14d of the neck 14, and in particular the external skirt 25 of the reducer 30.

[0182] Said skirts 35, 36, 37 being connected by a corresponding shoulder (not referenced) so as to form a stepped skirt whose external diameter decreases in stages along the extension axis, on the side opposite the container 10.

[0183] The second cylindrical skirt 36 comprises on its internal surface 36a an internal thread or tapping 36b cooperating with the external thread 16 carried by the first external surface 14c of the neck 14 of the container 10.

[0184] In the assembled position, the internal wall 34 of the cover 30 radially surrounds the entire reducer 20.

[0185] As illustrated, the cover 30 further comprises an end wall 38 extending radially at the upper end of the third cylindrical skirt 37 and located axially above the reducer 20 in the assembled position.

[0186] Said end wall 38 comprises an annular sealing lip 38a extending from a lower surface of said end wall 38 towards the reducer 20, in an oblique direction, inclined inwards.

[0187] The sealing lip 38 is intended to come into contact with the upper wall 23 in the assembled position and ensure the sealing of the assembly 1.

[0188] Alternatively, any other shape could be provided for the cover 30.

[0189] The example illustrated in [Fig.9], in which the same elements bear the same references, the internal skirt 21 of the reducer 20 comprises on its external surface 21b, a snap-fastening element 21d cooperating with a snap-fastening element 14e comple- provided on the internal surface 14b of the neck 14 of the container 10.

[0190] As illustrated, the snap-in element 21d is an annular bead extending radially outwardly from the outer surface 21b of the inner skirt 21 and the complementary snap-in element 14e is an annular groove.

[0191] Alternatively, a structural inversion could be provided in which the snap-fastening element 21d carried by the internal skirt 21 of the reducer 20 is an annular groove and in which the complementary snap-fastening element 14e is an annular bead extending in radial projection from the internal surface 14b of the neck 14 of the container 14 towards the inside.

[0192] The example illustrated in Figures 10A and 10B, in which the same elements bear the same references, the internal surface 25a of the external skirt 25 of the reducer 20 comprises at the end of each rounded junction 29a, 29b of the complementary relief 27, a snap-fastening element 25d cooperating with a corresponding complementary snap-fastening element 14f provided on the second external surface 14d of the neck 14 of the container 10.

[0193] The two latching elements 25d are here circumferentially offset by 180° from each other and the two complementary latching elements 14f are here circumferentially offset by 180° from each other.

[0194] In the case where the disengagement relief 18 comprises three rounded junctions 18a, 18b circumferentially offset at 120° from each other, the second external surface 14d of the neck 14 of the container 10 comprises three complementary latching elements 14f circumferentially offset at 120° from each other and the external skirt 25 of the reducer 20 comprises two latching elements 25d circumferentially offset at 120° from each other.

[0195] Each complementary snap-fastening element 14f is located axially between an annular junction 18a, 18b and the distal end 13 of the container 10.

[0196] As illustrated, each snap-in element 25d is a radial, non-annular projection extending radially from the inner surface 25a inwardly and each complementary snap-in element 14f is a non-annular notch extending over a portion of the circumference of the second outer surface 14d of the neck 14 of the container 10, circumferentially between two ramps 19a, 19b of two pairs 19 of ramps and radially.

[0197] Alternatively, as visible in Figures 1 1A and 1 1B, a structural inversion could be provided in which the internal surface 25a of the external skirt 25 of the reducer 20 comprises at the end of each rounded junction 29a, 29b of the complementary relief 27, a latching element 25e, in the form of a non-annular notch, cooperating with a complementary latching element 14g in the form of a non-annular radial projection extending radially from the second outer surface 14d of the neck 14 of the container 10 towards the outside.

[0198] The two latching elements 25e are here circumferentially offset by 180° from each other and the two complementary latching elements 14g are here circumferentially offset by 180° from each other.

[0199] In the case where the disengagement relief 18 comprises three rounded junctions circumferentially offset at 120° from each other, the second external surface 14d of the neck 14 of the container 10 comprises three complementary latching elements 14g circumferentially offset at 120° from each other and the external skirt 25 of the reducer 20 comprises two latching elements 25e circumferentially offset at 120° from each other.

[0200] Each snap-on projection 14g extends circumferentially over a portion of the circumference of the second outer surface 14d of the neck 14 of the container 10, between two ramps 19a, 19b of two pairs 19 of ramps.

[0201] In all of the embodiments, the container 10 and the cover 30 can be made of any plastic material using techniques such as injection stretch blow molding (ISBM), injection blow molding (IBM), extrusion molding (EBM), injection molding (IM), in particular of thermoplastic polymer, such as for example polypropylene (PP), polyethylene (PE), or polybutylene terephthalate (PBT), or even of a recycled plastic material, known by the abbreviation PCR or Post Consumer Recycling in English terms.

[0202] The reducer 20 is made in a single piece, for example by injection molding a plastic material, for example a thermoplastic polymer, such as for example a polyolefin material of the polyethylene and / or polypropylene (PE / PP) type, or even a recycled plastic material “PCR” or high density polyethylene (HDPE).

[0203] Thanks to the various provisions of the invention, the Applicant Company is able to offer its customers a cosmetic product packaging and distribution assembly 1 comprising a removable reducer of minimalist structure while guaranteeing good axial retention and sealing, thus reducing the environmental impact resulting both from the manufacture of this assembly, in particular via a limitation of the raw materials used, its packaging and its transport, in particular via a limitation of the mass of the assembly, or its end-of-life treatment.
