Description

Title of the invention: A sealing device for a product packaging and dispensing assembly, and a sealing assembly comprising such a device

[0001] The present invention relates to the field of packaging and distribution of 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 the sealing organs or stoppers intended to seal an opening of a container such as a bottle, tube or flask containing a product.

[0004] By way of non-limiting example, the product may be fluid, such as for example a cosmetic product, or any other fluid product, such as for example a food product, paint, or even a non-fluid product, for example a viscous product, such as for example glue, compote or a pasty product configured to flow.

[0005] More particularly, the present invention relates to closure devices, also known as closure caps, made of synthetic material generally comprising a hollow cylindrical body intended to be attached to the open end of the bottle to be closed and a cover fixed to the body and movable relative to said body between an open position of the bottle and a closed position of said bottle.

[0006] The cover is generally hinged to the body, for example by means of one or more hinges or joints.

[0007] The present invention also relates to packaging and distribution assemblies for a product, in particular cosmetics, comprising a bottle intended to contain the product and comprising a flow orifice and a sealing member mounted on said bottle and provided with a distribution orifice of a diameter smaller than the diameter of the flow orifice.

[0008] Conventionally, the fixing of such a closure element on the neck of a bottle is ensured by the cooperation of fixing means, such as thread / tapping systems or groove and snap-on projection systems, provided on the outer surface of the neck of the bottle and the inner surface of a fixing skirt provided on the closure element and adapted to extend radially around the neck of the bottle in the position of fixing the closure element on the neck of the bottle.

[0009] However, packaging assemblies including such a sealing element cannot be stored in an inverted position with the closing element in contact with a flat surface.

[0010] It is necessary to enlarge the sealing elements in order to ensure stability in the inverted storage position.

[0011] However, the enlargement of the sealing elements requires the use of a significant amount of material, particularly plastic, for the manufacture of the closing element.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] The present invention aims to overcome the above disadvantages and to improve the sealing devices in order to reduce the material used while ensuring good stability in an inverted position.

[0016] Another objective of the invention is to ensure good restitution of the product contained in the container of the product packaging and distribution assembly.

[0017] Another objective of the invention is to avoid the accumulation of water in the sealing device.

[0018] The invention relates to a sealing or closing device for a product packaging and distribution assembly, in particular a cosmetic product, comprising a container having an opening and delimiting an internal volume intended to receive the product.

[0019] The sealing member comprises a substantially cylindrical mounting body or skirt, extending along an elevation axis and configured to be mounted around a neck of the container.

[0020] The mounting skirt is axially delimited by an open lower end and a radial upper wall provided with a distribution orifice, in particular for the passage of the product contained in the container, the mounting skirt comprising removable fixing means configured to cooperate with the neck of the container.

[0021] The sealing member comprises an external skirt radially surrounding the mounting skirt and extending axially obliquely at a first non-zero angle from a lower end connected directly or indirectly to the mounting skirt to an upper end extending axially beyond the radial upper wall.

[0022] In other words, the upper end has a larger diameter than the lower end.

[0023] By "directly", it is meant that the lower end is connected to the mounting skirt without an intermediate element.

[0024] By "indirectly", it is understood that the lower end is connected to the mounting skirt by at least one intermediate element.

[0025] For example, the mounting skirt includes on its inner surface a tapping configured to cooperate with the thread carried by the neck of the container in the assembled position of the sealing member on the container.

[0026] The term "product" means a liquid, semi-liquid, or viscous product designed to flow out of a reservoir under the effect of gravity. The product may be, but is not limited to, a cosmetic product, such as a hygiene or skincare product. Alternatively, the product may be configured to flow out of the reservoir under the effect of pressure applied to the reservoir.

[0027] In other words, the outer skirt has a conical or inverted spindle shape Therefore, the large diameter upper end ensures the stability of the assembly in an inverted storage position.

[0028] The specific shape of the outer skirt makes it possible to reduce the amount of plastic material used, while maintaining good overall stability.

[0029] The outer skirt has a larger radial dimension in a longitudinal direction than in a transverse direction.

[0030] For example, the first angle defined between the outer skirt and the mounting skirt is between 30° and 60°, preferably equal to 45° in a plane comprising the elevation axis and a longitudinal axis

[0031] Preferably, the lower end of the outer skirt is connected to the open end of the mounting skirt.

[0032] Alternatively, the lower end of the outer skirt is connected to the mounting skirt at a distance from the open end of the mounting skirt.

[0033] According to one embodiment, the lower end of the outer skirt is indirectly connected to the mounting skirt by one or more portions, for example, via a radial portion and / or an oblique portion.

[0034] According to one embodiment, the outer skirt has a convex shape. Alternatively, the outer skirt could be provided to have a straight shape.

[0035] According to one example, the distribution orifice opens into a recess that projects axially inwards from the radial upper wall. Alternatively, the distribution orifice could be provided to open into a flat or substantially flat radial upper wall.

[0036] Advantageously, the sealing member further comprises a sealing skirt extending axially from the upper wall to the open end of the mounting skirt.

[0037] The sealing skirt is radially offset inwards relative to the mounting skirt, so that in the assembled position, the neck of the container is inserted radially between said sealing skirt and the mounting skirt.

[0038] In other words, the external surface of the sealing skirt is in radial sealing contact with the internal surface of the container neck in the assembled position.

[0039] In the assembled position, the radial upper wall of the obturation member is in axial contact with the upper end of the neck of the container.

[0040] Advantageously, the sealing member further comprises a hood or cover including a sealing lug or stud projecting axially inwards from an inner surface of the cover and articulated relative to the outer skirt by means of at least one joint or hinge about a transverse pivot axis, along a longitudinal axis perpendicular to the elevation axis, between an open position, in which the distribution orifice is free and a closed position, in which the distribution orifice is sealed by the sealing lug when said cover.

[0041] The connection of the cover to the outer skirt can be achieved for example by a so-called "film" hinge or a strip whose thickness is reduced at the pivot axis in order to give the hinge bending properties.

[0042] For example, the sealing lug includes a snap-on projection, for example an annular bead, cooperating with a complementary snap-on projection provided in the recess provided on the radial upper wall. This allows the cover to be held in the closed position.

[0043] Advantageously, the cover does not extend radially between the mounting skirt and the outer skirt in the closed position, so as to leave a radial space between the mounting skirt and the outer skirt in the closed position, and thus allow the water that might be contained in this space to pass through in order to limit any accumulation of water.

[0044] Preferably, the lid is in conformity in shape with the radial upper wall.

[0045] For example, the outer skirt includes a rear recess configured to be connected to the cover via the joint.

[0046] For example, the outer skirt includes a front recess connected to the radial upper wall by a radial junction.

[0047] For example, the front recess has a concave shape towards the inside.

[0048] For example, the outer skirt comprising two skirt parts each extending circumferentially between the front recess and the rear recess.

[0049] According to one embodiment, each skirt part includes an opening made in the thickness of the outer skirt, delimited axially between the lower end of the outer skirt and the upper end and extending between 50% and 90% of the total height of the outer skirt.

[0050] Such an openwork outer skirt makes it possible to further reduce the amount of plastic material used.

[0051] For example, the outer skirt further includes at least three stability studs projecting axially from the upper end of said outer skirt.

[0052] In the storage position, the stability pads are in contact with the flat surface. The stability pads improve the stability of the assembly in the storage position and prevent the accumulation of mold between the lid and the flat surface.

[0053] Preferably, the stability studs are regularly distributed around the circumference of the upper end of the outer skirt.

[0054] In particular, the stability pads are located at the outermost ends of the outer skirt along the transverse Y direction and the horizontal direction.

[0055] Advantageously, the lid further includes a gripping portion at the end opposite the hinges, extending beyond the front recess provided in the outer skirt to allow the user to handle the lid. This greater extension compared to known one-piece dispensing capsules offers greater ease of opening for the consumer while remaining protected against unintended opening, for example, during transport.

[0056] According to another aspect, the invention relates to a product packaging and dispensing assembly, particularly for cosmetics, extending axially along an axis of elevation and comprising a container having an opening and defining an internal volume for receiving the product, and a closure device as described above fixed to the container. The dispensing orifice of the closure device is in fluidic communication with the internal volume of the container in an assembled position.

[0057] The diameter of the distribution orifice of the sealing element is smaller than the diameter of the opening in the neck of the container. The sealing element thus forms a device for reducing the flow diameter of the product contained in the container.

[0058] For example, the container comprises a main hollow body extending axially along the axis of elevation between a closed lower end forming a bottom and an open upper end, opposite the lower end, forming a neck with an opening allowing access to the internal volume for receiving the product, the neck comprising a thread intended to cooperate with the thread provided on the sealing member.

[0059] Alternatively, any means of removable fixing of the sealing member in relation to the container could be provided.

[0060] The body of the container has, for example, a non-circular cross-section and the neck has a circular cross-section. Alternatively, the body of the container could have a circular cross-section or any other shape.

[0061] The product conditioning and distribution assembly is stored in an inverted position, i.e. the sealing member is in contact with a flat surface, such as for example a sanitary rim, for example a shower, a sink, a bathtub, a shower tray.

[0062] Preferably, in the storage position, the upper end and the upper surface of the lid are in contact with the flat surface.

[0063] It could also be provided that the upper end and the upper surface of the cover are offset from the flat surface along the vertical axis, to ensure support at the level of the external skirt or stability points.

[0064] If stability pads are present, in the storage position, the stability pads are in contact with the flat surface. The stability pads improve the stability of the assembly in the storage position and prevent the accumulation of mold between the lid and the flat surface.

[0065] The obturator is preferably symmetrical with respect to a median plane passing through the elevation axis.

[0066] For example, the container and the sealing member can be made of any plastic material using techniques such as stretch injection 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 polyethylene terephthalate (PET), or even of a recycled plastic material, known by the abbreviation PCR or Post Consumer Recycling in Anglo-Saxon terms.

[0067] The sealing element is preferably made in one piece, for example by injection molding of a plastic material, for example a polymer thermoplastic, such as polyethylene (PE) or recycled plastic “PCR” or high-density polyethylene (HDPE) or polypropylene (PP) or any thermoplastic elastomer.

[0080] In the following description, we consider an orthonormal basis X, Y, Z, with Z corresponding to an axis of elevation or extension representing the vertical direction in which we find:

[0081] - a longitudinal axis X, horizontal and extending from back to front on the [Fig.4];

[0082] - a horizontal transverse axis Y, perpendicular to the longitudinal axis X and extending from right to left across [Fig. 4]; and

[0083] - a vertical axis Z, orthogonal to the longitudinal axis X and transverse axis Y and extending from top to bottom on the [Fig.4].

[0084] The expressions "upper" and "lower" refer to the upper and lower parts of the figures with respect to the vertical direction Z.

[0085] The terms "interior" or "internal" and "exterior" or "external" refer to the interior of the product packaging and distribution assembly, the internal or interior parts being closer to the Z-Z' elevation axis than the external or exterior parts.

[0086] Figure 1 shows a set 1 for the conditioning and distribution of a product, in particular a cosmetic.

[0087] The term "product" means a liquid, semi-liquid, or viscous product intended to flow out of a reservoir under the effect of gravity. The product may be, but is not limited to, a cosmetic product, such as a hygiene or skincare product.

[0088] The packaging and distribution assembly 1 of a product includes a reservoir or container 10 and a sealing or closing device 20 for the neck of the container 10.

[0089] In the embodiment illustrated in the figures, the container 10 comprises a main hollow body 11 delimiting an internal volume (not visible in the figures) containing a product.

[0090] The container 10 extends axially along the elevation axis Z-Z' assumed to be vertical in the figures from a closed lower end forming a bottom 12 and from an open upper end 13, opposite the lower end 12, forming a neck (not visible in the figures) with an opening allowing access to the internal volume.

[0091] The body of the tank 10 can be made, for example, of rigid synthetic material.

[0092] The neck of the container 10 comprises, on its external surface, a thread (not shown) cooperating with a 22b thread provided on the sealing member 20.

[0093] Alternatively, any means of removable fixing of the sealing member 20 in relation to the container 10 could be provided.

[0094] As illustrated, the body 11 of the container 10 has, here, a non-circular cross-section and the neck has a circular cross-section. Alternatively, the body 11 of the container 10 could have a circular cross-section or any other shape.

[0095] As illustrated in figures 1 to 5, the obturator member 20 extends along the elevation axis Z-Z'.

[0096] As illustrated, the sealing member 20 comprises a substantially cylindrical body 22 or mounting skirt, extending along the elevation axis Z-Z', here shown in a vertical operating position, and configured to be mounted around the neck of the container 10.

[0097] The mounting skirt 22 is axially delimited by an open lower end 23 and a radial upper wall 24 provided with a distribution orifice 25 for the passage of the product contained in the container 10.

[0098] The mounting skirt 22 includes on its inner surface 22a a tapping 22b configured to cooperate with the thread carried by the neck of the container 10 in the assembled position of the sealing member 20 on the container 10.

[0099] The sealing member 20 further includes a sealing skirt 26 extending axially from the upper wall 24 to the open end 23 of the mounting skirt 22.

[0100] The sealing skirt 26 is radially offset inwards relative to the mounting skirt 22, so that in the assembled position, the neck of the container 10 is inserted radially between said sealing skirt 26 and the mounting skirt 22.

[0101] In other words, the external surface of the sealing skirt 26 is in radial sealing contact with the internal surface of the neck of the container 10 in the assembled position.

[0102] In the assembled position, the radial upper wall 24 of the obturation member 20 is in axial contact with the upper end of the neck of the container 10.

[0103] As illustrated, and in no way limitingly, the distribution port 25 opens into a recess 25a which projects axially inwards from the radial upper wall 24. Alternatively, the distribution port 25 could be provided to open into a flat or substantially flat radial upper wall 24.

[0104] The diameter of the distribution orifice 25 of the sealing member 20 is less than the diameter of the opening of the neck of the container 10.

[0105] The sealing element 20 thus forms a reducing element for the flow diameter of the product contained in the container 10.

[0106] As illustrated in figures 1 to 5, the sealing member 20 comprises an external skirt 27 radially surrounding the mounting skirt 22.

[0107] The outer skirt 27 extends axially from a lower end 27a connected to the open end 23 of the mounting skirt 22 to an upper end 27b extending axially beyond the radial upper wall 24.

[0108] Alternatively, as illustrated in [Fig. 4A], the outer skirt 27 extends axially from a lower end 27a connected to the mounting skirt 22 at a distance from the open end 23 of the mounting skirt 22 to an upper end 27b extending axially beyond the radial upper wall 24. In other words, the point of connection of the lower end 27a to the mounting skirt is offset axially along the extension axis Z-Z' towards the upper wall 24 by a non-zero axial distance, for example between 2% and 50% of the total axial length of the mounting skirt 22.

[0109] Generally, the outer skirt 27 extends axially from a lower end 27a connected to the mounting skirt 22.

[0110] Furthermore, as illustrated in Figures 1 to 5, the lower end 27a of the outer skirt 27 is connected directly to the mounting skirt 22.

[0111] Alternatively, it could be provided that the lower end 27a of the outer skirt 27 either connected indirectly to the mounting skirt 22, i.e. by one or more portions.

[0112] Thus, in the example illustrated in [Fig. 5A], the lower end 27a of the outer skirt 27 is indirectly connected to the mounting skirt 22 via a radial portion 27f. In this example, the outer skirt 27 has a straight shape. A convex shape could be provided for the outer skirt 27, as illustrated in [Fig. 5B].

[0113] In the example illustrated in [Fig. 5C], the lower end 27a of the outer skirt 27 is indirectly connected to the mounting skirt 22 via a radial portion 27f and an oblique portion 27g. In this example, the outer skirt 27 has a straight shape. A convex shape could be provided for the outer skirt 27.

[0114] In the example illustrated in [Fig. 5D], the lower end 27a of the outer skirt 27 is indirectly connected to the mounting skirt 22 via an oblique portion 27g. In this example, the outer skirt 27 has a straight shape. A convex shape could be provided for the outer skirt 27.

[0115] As illustrated in figures 1 to 4, 4A and 5, the outer skirt 27 has a convex shape for the outer skirt 27. Alternatively, a straight shape could be provided.

[0116] The outer skirt 27 extends obliquely relative to the mounting skirt 22 and defines a first angle al with said mounting skirt 22, visible on the [Fig.5].

[0117] The first angle al is here 45° in the XZ plane. In general, the first angle al is between 30° and 60° in the XZ plane.

[0118] The outer skirt 27 extends obliquely relative to the mounting skirt 22 and defines a second angle a2 with said mounting skirt 22, visible on the [Fig.4].

[0119] The second angle a2 is here 20° in the YZ plane. In general, the second angle a2 is between 10° and 30° in the XZ plane.

[0120] In general, the angles of inclination al, a2 of the outer skirt 27 depend on the height of the outer skirt 22 and the cross-section of the container, as well as the need for stability.

[0121] In other words, the upper end 27b has a larger diameter than the lower end 27a.

[0122] As illustrated, the outer skirt 27 includes a rear recess 28 configured to be connected to a lid 30.

[0123] As illustrated, the outer skirt 27 includes a front recess 29 connected to the wall superior radial 24 by a radial junction 29a.

[0124] The front recess 29 here has a concave shape towards the inside.

[0125] The outer skirt 27 includes skirt parts 27c extending circumferentially between the front recess 29 and the rear recess 28.

[0126] As illustrated in figures 1 to 5, the outer skirt 27 has a conical or inverted spindle shape, so the large diameter upper end 27b ensures the stability of the assembly 1 in an inverted storage position.

[0127] The specific shape of the outer skirt 27 makes it possible to reduce the amount of plastic material used, while maintaining good stability of the assembly 1.

[0128] The sealing member 20 further comprises a hood or cover 30 articulated relative to the outer skirt 27 by means of one or more joints 33 or hinges about a transverse pivot axis A0, along the longitudinal axis X, perpendicular to the elevation axis "L-TJ, between an open position, visible on [Fig.2A], in which the distribution orifice 25 is free and a closed position, visible on [Fig.2B] in which the distribution orifice 25 is closed by a lug or sealing stud 31 projecting axially inwards from an inner surface 32 of the cover 30 when said cover 30.

[0129] The sealing lug 31 includes a snap-on projection 31a, here an annular bead, cooperating with a complementary snap-on projection 25b provided in the recess 25a provided on the radial upper wall 24. This allows the cover 30 to be kept in the closed position in the storage position.

[0130] The connection of the cover 30 to the external skirt 27 can be achieved for example by a so-called "film" hinge or a strip whose thickness is reduced at the pivot axis A0 in order to give the hinge bending properties.

[0131] The cover 30 does not extend radially between the mounting skirt 22 and the outer skirt 27 in the closed position, so as to leave a radial space E between the mounting skirt 22 and the outer skirt 27 in the closed position of the cover, as seen in figures 2B and 5, and thus allow any water that might be contained in this space to pass through in order to limit any accumulation of water.

[0132] Preferably, the cover 30 is in conformity in shape with the radial upper wall 24.

[0133] The cover 30 further includes a gripping part 34 at the end opposite the hinges 33 and extending beyond the front recess 29 provided in the outer skirt 27 in order to allow the user to handle said cover 30.

[0134] The product packaging and distribution assembly 1 is stored in an inverted position, i.e. the sealing member 20 is in contact with a flat surface, such as for example a sanitary rim, for example a shower, a sink, a bathtub, a shower tray.

[0135] Preferably, in the storage position, the upper end 27b and the upper surface of the lid 30 are in contact with the flat surface.

[0136] Figures 6, 7A, 7B illustrate another embodiment of a sealing member 120 which differs only from the previous embodiment by the openwork shape of the external skirt 127 and the presence of stability studs 127e.

[0137] The references have simply been modified by adding a "1" in front.

[0138] Since assembly 1 is strictly identical to the previous embodiment, its description will not be repeated.

[0139] As illustrated in figures 6, 7A, 7B, the obturator member 120 extends along the elevation axis Z-Z'.

[0140] As illustrated, the sealing member 120 comprises a substantially cylindrical body 122 or mounting skirt, extending along the elevation axis Z-Z', here shown in a vertical operating position, and configured to be mounted around the neck of the container 10.

[0141] The mounting skirt 122 is axially delimited by an open lower end 123 and a radial upper wall 124 provided with a distribution orifice 125 for the passage of the product contained in the container 10.

[0142] The mounting skirt 122 includes on its inner surface 122a a tapping 122b configured to cooperate with the thread carried by the neck of the container 10 in the assembled position of the sealing member 120 on the container 10.

[0143] The sealing member 120 further includes a sealing skirt 126 extending axially from the upper wall 124 to the open end 123 of the mounting skirt 122.

[0144] The sealing skirt 126 is radially offset inwards relative to the mounting skirt 122, so that in the assembled position, the neck of the container 10 is inserted radially between said sealing skirt 126 and the mounting skirt 122.

[0145] In other words, the external surface of the sealing skirt 126 is in radial sealing contact with the internal surface of the neck of the container 10 in the assembled position.

[0146] As illustrated, and in no way limitingly, the distribution port 125 opens into a recess 125a which projects axially inwards from the radial upper wall 124. Alternatively, the distribution port 125 could be provided to open into a flat or substantially flat radial upper wall 124.

[0147] The diameter of the distribution orifice 125 of the sealing member 120 is less than the diameter of the opening of the neck of the container 10.

[0148] The sealing element 120 thus forms a reducing element for the flow diameter of the product contained in the container 10.

[0149] In the assembled position, the radial upper wall 124 of the obturation member 120 is in axial contact with the upper end of the neck of the container 10.

[0150] As illustrated in Figures 6, 7A, 7B, the sealing member 120 comprises an external skirt 127 radially surrounding the mounting skirt 122.

[0151] The outer skirt 127 extends axially from a lower end 127a connected to the open end 123 of the mounting skirt 122 to an upper end 127b extending axially beyond the radial upper wall 124.

[0152] The embodiment variants illustrated with reference to Figures 4A, 5A, 5B, 5C and 5D can be transposed to the embodiment illustrated in Figures 6, 7A and 7B.

[0153] The outer skirt 127 extends obliquely with respect to the mounting skirt 122 and defines a first angle (not referenced) with said mounting skirt 122.

[0154] The first angle here is 45° in the XZ plane. In general, the first angle is between 30° and 60° in the XZ plane.

[0155] The outer skirt 127 extends obliquely with respect to the mounting skirt 122 and defines a second angle (not referenced) with said mounting skirt 122.

[0156] The second angle here is 20° in the YZ plane. Generally, the second angle is between 10° and 30° in the XZ plane.

[0157] Generally, the angles of inclination of the outer skirt 127 depend on the height of the outer skirt 122 and the cross-section of the container, as well as the need for stability.

[0158] In other words, the upper end 127b has a larger diameter than the lower end 127a.

[0159] As illustrated, the outer skirt 127 includes a rear recess 128 configured to be connected to a cover 130 and a front recess 129 connected to the radial upper wall 124 by a radial junction 129a.

[0160] The recess before 129 here has a concave shape towards the inside.

[0161] The outer skirt 127 includes skirt parts 127c extending circumferentially between the front recess 129 and the rear recess 128.

[0162] Each skirt part 127c is here openwork, that is to say that each skirt part 127c includes an opening 127d made in the thickness of the outer skirt 127.

[0163] The opening 127d is axially delimited by the lower end 127a of the outer skirt 127 and the upper end 127b.

[0164] The opening 127d of each skirt part 127c preferably extends between 50% and 90% of the total height of the outer skirt 127.

[0165] The openwork outer skirt 127 allows for a further reduction in the amount of plastic material used.

[0166] The outer skirt 127 further includes a plurality of stability studs 127e projecting axially from the upper end 127b of said outer skirt 127.

[0167] The stability studs 127e are here regularly distributed around the circumference of the upper end 127b of the outer skirt 127.

[0168] As illustrated, the outer skirt 127 comprises three stability pads 127e per part skirt size 127c.

[0169] Alternatively, the outer skirt 127 could be provided to include at least three stability studs 127e.

[0170] It could be foreseen that in the previous embodiments described with reference to Figures 1 to 5, 4A, 5A, 5B, 5C, 5D, the outer skirt 27 also includes a plurality of stability studs.

[0171] As illustrated in the figures, the outer skirt 127 has a conical or inverted spindle shape, so the large diameter upper end 127b ensures the stability of the assembly 1 in an inverted storage position.

[0172] The specific shape of the outer skirt 127 makes it possible to reduce the amount of plastic material used, while maintaining good stability of the assembly 1.

[0173] The sealing member 120 further comprises a hood or cover 130 articulated relative to the outer skirt 127 by means of one or more joints 133 or hinges about a transverse pivot axis A0, along the longitudinal axis X, perpendicular to the elevation axis "L-TJ, between an open position, visible on [Fig.7A], in which the distribution orifice 125 is free and a closed position, visible on [Fig.7B], in which the distribution orifice 125 is sealed by a sealing lug or stud 131 projecting axially inwards from an inner surface 132 of the cover 130 when said cover 130.

[0174] The sealing lug 131 includes a snap-on projection 131a, here an annular bead, cooperating with a complementary snap-on projection 125b provided in the recess 125a provided on the radial upper wall 124. This allows the cover 130 to be kept in the closed position in the storage position.

[0175] The connection of the cover 130 to the external skirt 127 can be achieved for example by a so-called "film" hinge or a strip whose thickness is reduced at the pivot axis AO in order to give the hinge bending properties.

[0176] The cover 130 does not extend radially between the mounting skirt 122 and the outer skirt 127 in the closed position, so as to leave a radial space E between the mounting skirt 122 and the outer skirt 127 in the closed position of the cover, as seen in Figures 7B, and thus allow the water that might be contained in this space to pass through in order to limit any accumulation of water.

[0177] Preferably, the cover 130 is in conformity in shape with the radial upper wall 124.

[0178] The cover 130 further includes a gripping part 134 at the end opposite the hinges 133 and extending beyond the front recess 129 provided in the outer skirt 127 in order to allow the user to handle said cover 130.

[0179] The product packaging and distribution assembly 1 is stored in an inverted position, i.e. the sealing member 120 is in contact with a flat surface, such as for example a sanitary rim, for example a shower, a sink, a bathtub, a shower tray.

[0180] Preferably, in the storage position, the stability pads 127e are in contact with the flat surface.

[0181] Thanks to the various features of the invention, the Applicant Company is able to offer its customers a cosmetic product packaging and distribution unit comprising a removable sealing element with a minimalist structure while ensuring good stability in a storage position and the absence of water retention, thus reducing the environmental impact resulting from both the manufacture of this unit, 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 unit, or its treatment at the end of its life.
