Description

Title of the invention: Packaging and dispensing assembly for a cosmetic product and associated manufacturing process

[0001] The present invention relates to a packaging and dispensing assembly for a cosmetic product comprising:

[0002] - a substantially tubular main body extending substantially along an axis longitudinal and delimiting a storage area for the cosmetic product;

[0003] - a cosmetic product distribution head welded to the main body and suitable for distribute the cosmetic product contained in the storage unit;

[0004] the distribution head comprising:

[0005] - a support comprising a transverse wall extending substantially perpendicular to the longitudinal axis and defining a receiving opening for a dispensing nozzle, the transverse wall comprises an internal surface oriented towards the storage enclosure and an external surface opposite the internal surface; and

[0006] - the dispensing nozzle comprising a tubular dispensing wall extending through the opening defined by the transverse wall of the support and defining a passage for the distribution of the cosmetic product.

[0007] A cosmetic product is, for example, a hair product, a hygiene product, a facial and / or body care product, a makeup product, or a sun protection product. More generally, a cosmetic product is 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.

[0008] FR 3 105 971, EP 4 291 501, US 4 934 591, EP 3 741 696 and WO 2022 / 053879 disclose product dispensing packaging assemblies.

[0009] In prior art assemblies, specific fasteners are provided for mounting the distribution head onto the main body. The addition of these fasteners increases the mass of the assembly. Furthermore, it is known that such fasteners are made of materials that are difficult to recycle.

[0010] Also, in certain known assemblies, the main body and the distribution head are adapted to cooperate with such fastening elements. In particular, additional thicknesses are added to portions of the main body and the distribution head, these portions then being suitable for cooperating by hooking, compression or otherwise with the fastening elements.

[0011] However, despite the use of such fastening elements, it is noted that the assemblies in question have areas of weakness at the level of these fastenings. When such an assembly is subjected to an impact (for example, if dropped onto a surface), the main body, the dispensing head support, and the dispensing nozzle may separate. Such separation can lead to the cosmetic product leaking out of the storage container.

[0012] The aim of the invention is therefore to propose a packaging and distribution system for a cosmetic product whose robustness is improved while limiting its mass.

[0013] To this end, the invention relates to an assembly of the aforementioned type, in which:

[0014] - the distribution head support further comprises a fixing ring defining a receiving groove for a free peripheral end of the main body, the free peripheral end of the main body being welded to the fixing ring by a first weld extending into the receiving groove; and

[0015] - the distribution nozzle of the distribution head has a peripheral rim transverse extending projecting from the tubular distribution wall substantially perpendicular to the longitudinal axis, the peripheral transverse rim being welded to the internal surface of the transverse wall of the distribution head support by a second weld.

[0016] Thanks to these features, the robustness of the cosmetic product packaging and dispensing assembly is improved. In particular, the attachment of the main body to the dispensing head support and the attachment of the dispensing nozzle to the dispensing head support are made more robust. Specifically, the receiving groove forms a dedicated space for attaching the main body to the support. Furthermore, attaching the transverse peripheral rim to the inner surface of the transverse wall increases the attachment surface of the nozzle to the support, and the interaction of the rim with the transverse wall reduces the risk of the nozzle being pulled away from the support. Finally, the use of welding eliminates the need for additional parts that would add weight to the assembly.

[0017] According to one variant, the fixing ring comprises:

[0018] - an internal peripheral skirt extending substantially parallel to the axis longitudinal;

[0019] - an external peripheral skirt extending substantially parallel to the axis longitudinal;

[0020] - an intermediate annular wall connecting the inner peripheral skirt and the skirt external device;

[0021] the receiving groove being delimited by the inner peripheral skirt, the outer peripheral skirt and the intermediate annular wall.

[0022] Thanks to these features, the rigidity of the mounting ring is improved. In addition, the receiving groove is radially delimited internally and externally by the peripheral skirts, which makes it possible to create a dedicated space for mounting the main body, in which welding can be easily carried out.

[0023] According to another variant, the first weld extends:

[0024] - between the inner peripheral skirt of the fixing crown and an internal surface of the main body; and

[0025] - between the outer peripheral skirt of the fixing crown and an external surface of the main body.

[0026] Thanks to these features, the first weld connecting the main body and the distribution head support extends over both the inner and outer surfaces of the main body. The overall robustness is further improved.

[0027] According to another variant, the intermediate annular wall of the fixing ring forms a bearing surface suitable for cooperating with a support surface on which the assembly is intended to rest so that the longitudinal axis extends substantially perpendicularly to said support surface.

[0028] Thanks to these characteristics, the distribution head support also forms a base for the assembly on which the main body can rest when the assembly is placed on a surface.

[0029] According to another variant, an external peripheral surface of the tubular distribution wall is applied against an internal annular surface of the distribution head support, said internal annular surface delimiting the receiving orifice of the distribution nozzle.

[0030] Thanks to these features, the sealing of the dispensing head is improved. Indeed, the risk of cosmetic product leaking through the receiving orifice of the dispensing nozzle is reduced. Furthermore, it is prevented from the cosmetic product coming into direct contact with the internal annular surface of the dispensing head support. It is therefore possible to designate internal layers of the transverse wall of the support to be made of a material with a permeability lower than that of external layers of the transverse wall of the support, which, for example, have a permeability sufficiently low to prevent the passage of the cosmetic product.

[0031] According to another variant, the main body comprises a tubular wall delimiting the storage enclosure for the cosmetic product and extending substantially along the longitudinal axis,

[0032] each of the tubular wall of the main body and of the transverse wall of the distribution head support comprising:

[0033] - an inner layer oriented towards the storage enclosure of the cosmetic product;

[0034] - an outer layer opposite to the inner layer;

[0035] - at least one layer of thermoplastic material arranged between the inner layer and the outer layer;

[0036] - at least one layer of paper arranged between the inner layer and the outer layer.

[0037] Thanks to these characteristics, the proportion of thermoplastic material in the cosmetic product packaging and dispensing assembly is reduced. The use of paper improves the recyclability of the assembly.

[0038] According to another embodiment, the free peripheral end of the main body is formed by a free peripheral end of the tubular wall of the main body,

[0039] the first weld being formed by:

[0040] - a portion of the inner layer of the tubular wall of the main body at the end free peripheral of the tubular wall of the main body;

[0041] - a portion of the outer layer of the tubular wall of the main body at the end free peripheral of the tubular wall of the main body; and / or

[0042] - a portion of the inner layer of the transverse wall of the head support distribution delimiting the receiving throat.

[0043] Thanks to these characteristics, it is easier to weld the main body to the distribution head support, since it is sufficient to weld the internal and external layers of the tubular wall of the main body onto the distribution head.

[0044] According to another variant, the dispensing nozzle is made of a thermoplastic material,

[0045] the second weld being formed by:

[0046] - a portion of the inner layer of the transverse wall of the head support distribution arranged at the periphery of the receiving orifice of the distribution nozzle;

[0047] - a portion of the transverse peripheral rim of the dispensing nozzle of the head distribution.

[0048] Thanks to these features, it is easier to weld the distribution nozzle to the distribution head support, since it is sufficient to weld the transverse peripheral rim of the distribution nozzle onto the inner layer of the transverse wall of the distribution head support.

[0049] According to another embodiment, the dispensing nozzle further comprises a movable sealing element mounted on the tubular distribution wall between:

[0050] - a closing position in which the closing element closes the passage distribution of the cosmetic product so as to prevent the passage of the cosmetic product through the distribution passage;

[0051] - a release position in which the sealing element extends away from the distribution passage of the cosmetic product so as to allow the passage of the cosmetic product through the distribution passage.

[0052] Thanks to these features, a user of the assembly can easily manipulate the dispensing head to protect the cosmetic product when not using the assembly.

[0053] According to another variant, the main body and the transverse wall of the support are formed from a cellulosic material, in particular a multilayer laminate comprising at least one paper layer and at least one fusible layer extending over a weld face.

[0054] Thanks to these characteristics, paper is used in a greater proportion for the manufacture of the assembly compared to the prior art. This notably facilitates the recycling of the assembly.

[0055] The invention further relates to a method for manufacturing a packaging and dispensing assembly for a cosmetic product as described above, the method comprising the following steps:

[0056] - supply of the main body, the dispensing head support and the nozzle distribution of the distribution head;

[0057] - making the second weld between the transverse peripheral edge of the distribution nozzle of the distribution head and the internal surface of the transverse wall of the distribution head support; and

[0058] - making the first weld between the free peripheral end of the body main and fixing crown.

[0059] Thanks to these characteristics, the manufacturing process is made easier and the assembly obtained through this process is more robust.

[0060] The invention will become clearer upon reading the following description, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0061] [Fig-1] [Fig.1] is a simplified schematic perspective illustration for the purpose of underside of a packaging and distribution unit for a cosmetic product, according to the invention;

[0062] [Fig.2] [Fig.2] is a simplified schematic illustration of a portion of the whole of [Fig.1], in section along the longitudinal axis;

[0063] [Fig.3] [Fig.3] is a simplified schematic cross-sectional illustration of a wall tubular of a main body or of a transverse wall of a support of a distribution head of the whole of the [Fig.l];

[0064] [Fig.4] [Fig.4] is a flowchart illustrating a manufacturing process for a cosmetic product packaging and distribution assembly, according to the invention.

[0065] With reference to figures 1 to 3, a packaging and distribution assembly 10 for a cosmetic product according to the invention is disclosed.

[0066] The assembly 10 comprises a main body 14 and a distribution head 40.

[0067] The main body 14 is substantially tubular.

[0068] The main body 14 extends substantially along a longitudinal axis A-A'.

[0069] The main body 14 delimits a storage enclosure 16 for the cosmetic product.

[0070] Advantageously, the main body 14 includes a tubular wall 18 delimiting the storage enclosure 16.

[0071] The tubular wall 18 extends substantially along the longitudinal axis A-A'.

[0072] The main body 14, in particular the tubular wall 18 of the main body 14, extends along the longitudinal axis A-A' between a free peripheral end 14A and an end 14B opposite to the free peripheral end 14A.

[0073] In the example illustrated in [Fig.1], the end 14B opposite the free peripheral end 14A is defined by a weld 20 closing the main body 14, in particular the tubular wall 18, onto itself.

[0074] In an unillustrated variant, the main body 14 includes a bottom wall defining the end 14B opposite the free end 14A and extending substantially perpendicularly to the longitudinal axis A-A' to delimit the storage enclosure 16.

[0075] The free peripheral end 14A of the main body 14, in particular of the tubular wall 18 of the main body 14, is welded to a fixing ring 54 of a support 42 of the distribution head 40 by a first weld 32 extending into a receiving groove 56.

[0076] Advantageously, the main body 14 is formed from a cellulosic material, in particular a multilayer laminate comprising at least one paper layer 22D and at least one fusible layer 22A, 22B extending over a weld face.

[0077] Advantageously, with reference to [Fig. 3], the tubular wall 18 of the main body 14 includes:

[0078] - an internal 22A fusible layer oriented towards the product storage enclosure cosmetics;

[0079] - an outer fusible layer 22B opposite to the inner layer;

[0080] - at least one layer of thermoplastic material 22C arranged between the layer internal 22A fuse and external 22B fuse layer;

[0081] - at least one layer of 22D paper arranged between the internal fusible layer 22A and the 22B fusible outer layer.

[0082] According to a particular example, the tubular wall 18 of the main body 14, in particular the multilayer laminate, comprises, from the inside out:

[0083] - the inner layer;

[0084] - a first layer of thermoplastic material;

[0085] - a first layer of paper;

[0086] - a second layer of thermoplastic material;

[0087] - a second layer of paper;

[0088] - the outer layer.

[0089] The internal fusible layer 22A is intended to preserve and protect the cosmetic product and to prevent leakage of the cosmetic product into other layers.

[0090] For example, the fusible inner layer 22A is made of thermoplastic material, for example, petroleum-based material such as polyethylene or ethylene vinyl alcohol, and / or bio-based material such as polyhydroxyalkanoate. The combination of these materials makes it possible, in particular, to improve the impermeability of the inner layer 22A to water and gas.

[0091] In particular, the internal fusible layer 22A has the following characteristics:

[0092] - a basis weight between 20 g / m2 and 100 g / m2, for example substantially equal to 70 g / m2;

[0093] - a thickness between 20 pm and 100 pm, for example substantially equal to 70 pm.

[0094] The fusible outer layer 22B is intended to ensure impermeability to water and grease.

[0095] For example, the fusible outer layer 22B is made of thermoplastic material, for example petroleum-based material, such as polyethylene, and / or bio-based material, such as polyhydroxyalkanoate. Advantageously, the fusible outer layer 22B further comprises a water-based bio-based outer coating.

[0096] In particular, the outer layer 22B has the following characteristics:

[0097] - a basis weight between 5 g / m2 and 30 g / m2, for example approximately equal to 10 g / m2;

[0098] - a thickness between 5 pm and 30 pm, for example substantially equal to 11 pm.

[0099] In particular, the inner layer 22A and outer layer 22B are made of a hot-melt material which, as will be described below, is capable of melting at least partially when subjected to a temperature above a certain melting temperature threshold, in order to form welds. The melting temperature threshold is, for example, between 120°C and 200°C.

[0100] At least one layer of thermoplastic material 22C is in particular intended to form an impermeable barrier intended to prevent the passage of the cosmetic product through the tubular wall 18 of the main body 14.

[0101] For example, at least one layer of thermoplastic material 22C comprises polyethylene and / or ethylene vinyl alcohol and / or polypropylene.

[0102] At least one layer of 22D paper is intended to contribute to the rigidity of the main body, in particular as a replacement for plastics traditionally used for this purpose.

[0103] For example, at least one layer of 22D paper comprises paper pulp, or pulp, comprising plant cellulosic fibers selected in particular from wood fibers, cotton fibers, bamboo fibers, bagasse, and / or mixtures thereof.

[0104] Advantageously, at least one layer of 22D paper has the following characteristics:

[0105] - a weight between 180 g / m2 and 350 g / m2;

[0106] - a thickness between 200 qm and 450 qm.

[0107] Advantageously, the tubular wall 18 of the main body 14 comprises a mass proportion of paper greater than or equal to 70%, in particular greater than or equal to 75%.

[0108] Advantageously, the first weld 32 is formed by:

[0109] - a portion of the inner layer 22A of the tubular wall 18 of the main body 14 at the free peripheral end 14A of the tubular wall 18 of the main body 14, in particular a portion of the inner layer 22A of an annular portion of the free end 18A of the tubular wall 18;

[0110] - a portion of the outer layer 22B of the tubular wall 18 of the main body 14 at the free peripheral end 14A of the tubular wall 18 of the main body 14, in particular a portion of the outer layer 22B of the free end annular portion 18A; and / or

[0111] - a portion of the internal layer 92A of the transverse wall 44 (described below) of the support 42 of the distribution head 40 delimiting the receiving groove 56.

[0112] The distribution head 40 is welded onto the main body 14.

[0113] The distribution head 40 is suitable for distributing the cosmetic product contained in storage enclosure 16.

[0114] The distribution head 40 includes the support 42 and a distribution nozzle 70.

[0115] Advantageously, as illustrated in [Fig. 1], the distribution head 40 further comprises a sealing element 86.

[0116] Even more advantageously, the distribution head 40 further includes a hinge 90 mechanically linking the sealing element 86 and the distribution nozzle 70.

[0117] The support 42 of the distribution head 40 includes a transverse wall 44 and the fixing ring 54.

[0118] The transverse wall 44 extends substantially perpendicularly to the longitudinal axis A-A'.

[0119] As described below, the transverse wall 44 is welded to the main body 14, in particular to the tubular wall 18 of the main body 14.

[0120] The transverse wall 44 delimits an orifice 46 for receiving the dispensing nozzle 70.

[0121] In particular, the transverse wall 44 includes an internal annular surface 48 delimiting the receiving orifice 46.

[0122] The transverse wall 44 comprises an internal surface 50A oriented towards the storage enclosure 16 and an external surface 50B opposite the internal surface 50A.

[0123] Advantageously, the transverse wall 44 is formed by a cellulosic material, in particular a multilayer laminate comprising at least one layer of paper 92D and at least one fusible layer 92A, 92B extending over a weld face.

[0124] Further advantageously, with reference to [Fig. 3], the transverse wall 44, in particular the multilayer laminate, comprises:

[0125] - an internal 92A fusible layer oriented towards the product storage enclosure 16 cosmetics;

[0126] - an outer fusible layer 92B opposite to the inner layer;

[0127] - at least one layer of 92C thermoplastic material arranged between the layer internal 92A fuse and external 92B fuse layer;

[0128] - at least one layer of 92D paper arranged between the internal fusible layer 92A and the 92B fusible outer layer.

[0129] The internal fusible layer 92A of the transverse wall 44 is intended to preserve and protect the cosmetic product and to prevent leakage of the cosmetic product into other layers.

[0130] For example, the inner layer 92A of the transverse wall 44 is made of thermoplastic material, for example petroleum-based material such as polyethylene or ethylene vinyl alcohol, and / or bio-based material such as polyhydroxyalkanoate. The combination of these materials makes it possible, in particular, to improve the impermeability of the inner layer 22A to water and gas.

[0131] In particular, the inner layer 92A of the transverse wall 44 has the following characteristics:

[0132] - a weight between 20 g / m2 and 100 g / m2;

[0133] - a thickness between 20 pm and 100 pm.

[0134] The outer layer 92B of the transverse wall 44 is intended to ensure impermeability to water and grease.

[0135] For example, the outer layer 92B of the transverse wall 44 is made of thermoplastic material, for example petroleum-based material, such as polyethylene, and / or bio-based material, such as polyhydroxyalkanoate. Advantageously, the fusible outer layer 92B further comprises a water-based bio-based outer coating.

[0136] In particular, the outer layer 92B of the transverse wall 44 has the following characteristics:

[0137] - a weight between 5 g / m2 and 30 g / m2;

[0138] - a thickness between 5 pm and 30 pm.

[0139] In particular, the inner 92A and outer 92B layers of the transverse wall 44 are made of a hot-melt material which, as will be described below, is capable of melting at least partially when subjected to a temperature above the melting temperature threshold, to form welds.

[0140] At least one layer of thermoplastic material 92C of the transverse wall 44 is in particular intended to form an impermeable barrier intended to prevent the passage of the cosmetic product through the transverse wall 44.

[0141] For example, at least one layer of thermoplastic material 92C of the transverse wall 44 comprises polyethylene and / or ethylene vinyl alcohol and / or polypropylene.

[0142] At least one layer of 92D paper of the transverse wall 44 is intended to contribute to the rigidity of the main body, in particular as a replacement for plastics traditionally used for this purpose.

[0143] For example, at least one layer of 92D paper of the transverse wall 44 comprises paper pulp, or pulp, comprising plant cellulosic fibers selected in particular from wood fibers, cotton fibers, bamboo fibers, bagasse, and / or mixtures thereof.

[0144] Advantageously, at least one layer of 92D paper of the transverse wall 44 has the following characteristics:

[0145] - a weight between 180 g / m2 and 350 g / m2;

[0146] - a thickness between 200 qm and 450 qm.

[0147] Advantageously, the transverse wall 44 comprises a mass proportion of paper greater than or equal to 70%, in particular greater than or equal to 72%.

[0148] The fixing ring 54 delimits the receiving groove 56 of the free peripheral end 14A of the main body 14, in particular of the free peripheral end 14A of the tubular wall 18 of the main body 14.

[0149] Advantageously, as illustrated in [Fig. 2], the fixing ring 54 is formed by an external peripheral portion of the transverse wall 44. In other In terms, the fixing ring 54 and the transverse wall 44 form a single piece.

[0150] In particular, the fixing crown 54 includes an internal peripheral skirt 58, an external peripheral skirt 60 and an intermediate annular wall 62.

[0151] The internal peripheral skirt 58 extends substantially parallel to the longitudinal axis A-A', particularly with regard to the internal surface of the free end annular portion 18A of the tubular wall 18.

[0152] The external peripheral skirt 60 extends substantially parallel to the longitudinal axis A-A', in particular with regard to the external surface of the free end annular portion 18A of the tubular wall 18.

[0153] The intermediate annular wall 62 connects the inner peripheral skirt 58 and the outer peripheral skirt 60.

[0154] In particular, the intermediate annular wall 62 extends substantially perpendicularly to the longitudinal axis A-A' from the inner peripheral skirt 58 to the outer peripheral skirt 60.

[0155] For example, the intermediate annular wall 62 forms a bearing surface 64 suitable for cooperating with a support surface on which the assembly 10 is intended to rest so that the longitudinal axis A-A' extends substantially perpendicularly to said support surface.

[0156] In particular, the assembly 10 is able to rest in equilibrium on the bearing surface 64 when it is at rest on the support surface.

[0157] The receiving groove 56 is advantageously delimited by the inner peripheral skirt 58, the outer peripheral skirt 60 and the intermediate annular wall 62.

[0158] With reference to [Fig.2], the transverse wall 44 of the support 42 of the distribution head 40, in particular the central portion of the transverse wall 44, and the fixing ring 54, in particular the internal peripheral skirt 58 of the fixing ring 54, define a substantially cylindrical space 66 in which the distribution nozzle 70 extends.

[0159] The first weld 32 extends into the receiving groove 56 in order to mechanically connect the main body 14 and the support 42, in particular the tubular wall 18 of the main body 14 and the fixing ring 54 of the support 42.

[0160] Advantageously, the first weld 32 extends between the inner peripheral skirt 58 of the fixing ring 54 and an inner surface 15A of the main body 14 of the assembly 10. In particular, the first weld 32 extends between the inner peripheral skirt 58 and the inner surface of the free end annular portion 18A of the tube wall 18 in order to mechanically connect the inner peripheral skirt 58 and the inner surface of the free end annular portion 18A of the tube wall 18.

[0161] Advantageously, the first weld 32 further extends between the outer peripheral skirt 60 of the fixing ring 54 and an external surface 15B of the main body 14 of the assembly 10. In particular, the first weld 32 extends between the outer peripheral skirt 60 and the external surface of the free end annular portion 18A of the tube wall 18 in order to mechanically connect the outer peripheral skirt 60 and the external surface of the free end annular portion 18A of the tube wall 18.

[0162] Even more advantageously, the first weld 32 extends further between the intermediate annular wall 62 and the free end 14A of the tubular wall 18.

[0163] The dispensing nozzle 70 comprises a tubular dispensing wall 72 and a transverse peripheral rim 78.

[0164] The dispensing nozzle 70 is made of a thermoplastic material, for example polyethylene, polypropylene, a mixture of polyethylene and polypropylene, polyethylene terephthalate.

[0165] In particular, the material of the dispensing nozzle 70 is a hot-melt material which, as will be described below, is capable of melting at least partially when subjected to a temperature above the melting temperature threshold, to form welds.

[0166] The tubular distribution wall 72 extends through the orifice 46 delimited by the transverse wall 44 of the support 42.

[0167] The tubular distribution wall 72 delimits a passage 74 for the distribution of the cosmetic product.

[0168] In particular, as seen in [Fig.2], an external peripheral surface 72A of the tubular distribution wall 72 is applied against the internal annular surface 48 of the support 42 of the distribution head 40.

[0169] The transverse peripheral rim 78 extends projecting from the tubular distribution wall 72 substantially perpendicular to the longitudinal axis A-A'.

[0170] The transverse peripheral rim 78 is welded to the internal surface 50A of the transverse wall 44 of the support 42 of the distribution head 40 by a second weld 82.

[0171] The second weld 82 is, for example, formed by:

[0172] - a portion of the inner layer of the transverse wall 44 of the support 42 of the head distribution 40 arranged at the periphery of the receiving orifice 46 of the distribution nozzle 70;

[0173] - a portion of the transverse peripheral rim 78 of the dispensing nozzle 70 of the distribution head 40.

[0174] The sealing element 86 is movably mounted on the tubular distribution wall 72, in particular movable in rotation on the hinge 90, between a sealing position and a release position.

[0175] In the sealing position, the sealing element 86 seals the cosmetic product distribution passage 74 so as to prevent the cosmetic product from passing through the distribution passage 74.

[0176] In the release position (visible in Figures 1 and 2), the sealing element 86 extends away from the cosmetic product distribution passage 74 so as to allow the cosmetic product to pass through the distribution passage 74.

[0177] In what follows, with reference to [Fig.4], a method 100 for manufacturing assembly 10 is described.

[0178] The process 100 includes a step 110 of supplying the main body 14, the support 42 of the distribution head 40 and the distribution nozzle 70 of the distribution head 40.

[0179] Advantageously, the method 100 then includes a step 120 of arranging the dispensing nozzle 70 through the receiving orifice 46, in particular so that the transverse peripheral rim 78 of the dispensing nozzle 70 is applied against the internal surface 50A of the transverse wall 44 of the support 42 of the dispensing head 40.

[0180] The process 100 further comprises a step 130 of carrying out the second weld 82 between the transverse peripheral rim 78 of the distribution tip 70 of the distribution head 40 and the internal surface 50A of the transverse wall 44 of the support 42 of the distribution head 40.

[0181] For example, the second weld 82 is made by hot air welding or by ultrasonic welding.

[0182] Advantageously, the method 100 then includes a step 140 of arranging the main body 14 relative to the support 42 of the distribution head 40, in particular so that the free peripheral end 14A of the main body 14A extends into the receiving groove 56.
