Description

[0001] This invention relates to the field of packaging and dispensing products, particularly cosmetic products.

[0002] In particular, within the meaning of this invention, "cosmetic products" should be understood as products as defined in Regulation (EC) 1223 / 2009 of the European Parliament and the Council of 30 November 2009 concerning cosmetic products.

[0003] More specifically, the present invention relates to the field of components for packaging and dispensing products, particularly cosmetic products, including: a bottle intended to contain the product and including a flow orifice; a reducer mounted on the bottle and having a dispensing orifice with a diameter smaller than that of the flow orifice; and a cap intended to close the dispensing orifice of the reducer in a closed position.

[0004] Developing ecologically responsible and environmentally friendly solutions that take environmental issues into account has become a major concern in addressing global challenges.

[0005] Therefore, it is necessary to demonstrate that products must be designed to reduce the amount of materials used and / or replace and / or use recyclable materials with more environmentally friendly ones in order to reduce the carbon footprint of the product.

[0006] In this context, it is important to develop packaging that generates less waste and is optimized, particularly for the volume of products being transported, especially by redesigning packaging and / or redefining packaging dimensions to reduce packaging volume and weight.

[0007] The aim is to propose 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 known as “packaging.”

[0008] This invention forms part of a strategy for developing refillable packaging for cosmetic products, and particularly for personal care products such as shampoos or laundry detergents.

[0009] Typically, whether in the packaging of cosmetic products or other products, adapters are usually clamped tightly to the container and cannot be removed without damaging it. Specifically, it is possible to remove the adapter from the container using a screwdriver, corkscrew, or other similar tool, but it is difficult. However, such removal damages the adapter, making it impossible to reposition it while ensuring a good seal between the adapter and the container.

[0010] See reference JP 2002 – 166958A, which proposes a reducer that is fastened to the neck of a container by a snap-fit ​​and includes a system for preventing the reducer from being removed from the container.

[0011] This solution does not allow for the removal of the reducer from the container without damaging it. Furthermore, the reducers and containers described in this document come in various shapes, which complicates the manufacture of these components and increases the amount of material used.

[0012] Therefore, the object of the present invention is to overcome the above-mentioned disadvantages and improve product packaging and dispensing components, which include: a container; and a reducer having the diameter of the dispensing orifice of the container, mounted on the container, with the aim of enabling the reducer to be removed without damaging it.

[0013] Another objective of this invention is to simplify the manufacture of product packaging and dispensing components.

[0014] The subject of this invention is an assembly for packaging and dispensing products, particularly cosmetic products, which extends axially along a vertical viewing axis and includes a reservoir or container having an opening and defining an internal volume intended to receive the product.

[0015] The component further includes a reducer that is fastened to the container and includes a dispensing orifice that is in fluid communication with the internal volume of the container when in the assembled position, the inner diameter of the dispensing orifice being smaller than the inner diameter of the container's opening.

[0016] The component further includes a cap or cover that is removably fastened to the container and configured to close the distributor orifice of the reducer in the assembled position.

[0017] The reducer is removably fastened to the container by screwing it on.

[0018] The term "tightening by screwing" should be understood as referring to the threads engaging with each other, with the aim of separating the reducer from the container solely by the relative rotational movement of the reducer relative to the container.

[0019] The container can be removably fastened to it by twisting, allowing it to be refilled when it is empty.

[0020] "Product" is understood to be a liquid, semi-liquid, or viscous product intended to flow from a reservoir under the influence of gravity. In a completely non-limiting manner, a product can be a cosmetic product, such as a hygiene product or a personal care product.

[0021] Therefore, the reducer is a component used to reduce the flow diameter of the product contained in the container.

[0022] Advantageously, the container includes a body that extends axially along a vertical viewing axis between a closed lower end forming a bottom and an open upper end opposite to the lower end, the open upper end forming a stepped neck and having an opening that allows access to an internal volume for receiving the product.

[0023] The stepped neck includes: - A first neck, which is connected to the body of the container via a first engagement portion (e.g., a shoulder), and particularly includes on its outer cylindrical surface a first external thread designed to mate with a tapped thread or a first internal thread provided on the cap; and - A second neck, which is connected to the first neck via a second engagement (e.g., a shoulder), and includes a second thread designed to mate with a corresponding thread carried by the reducer.

[0024] Typically, the thread carried by the second neck of the container mates with the corresponding thread carried by the reducer, allowing the reducer to be removably fastened to the container by screwing.

[0025] In other words, the axial fixation of the reducer on the container is achieved through the engagement of the threads.

[0026] "Shoulder" is understood as any surface that is substantially perpendicular to the vertical line of view of a cylindrical component (in this case, the vertical line of view of the container) resulting from a sudden change in diameter.

[0027] In other words, the first neck is radially recessed inward relative to the body, and the second neck is radially recessed inward relative to the first neck.

[0028] Typically, a stepped neck includes a stepped cylindrical outer surface, which includes a first outer surface of a first neck carrying a first thread and a second outer surface of a second neck carrying a second thread, the first outer surface and the second outer surface being connected by a second joint (preferably a shoulder).

[0029] As a variant, the first neck can be connected to the body of the container via a joint with an inclined ramp.

[0030] It may also provide a combination of a shoulder and a body of the container with a first neck; the second neck extends directly from the first neck along the vertical viewing axis, without any intermediate elements between the two necks.

[0031] Preferably, the first internal thread of the first neck is offset axially and radially relative to the second thread of the second neck.

[0032] In other words, the second thread is axially positioned above the first thread in the direction of the vertical viewing axis, and the second thread is positioned radially recessed relative to the first thread.

[0033] Advantageously, the reducer includes a radially upper wall provided with a dispensing orifice, the reducer including at least one mounting skirt extending from the radially upper wall and including a corresponding thread.

[0034] For example, and in a completely non-limiting manner, the reducer includes a boss that projects axially outward from the radial upper wall, and a dispensing orifice opens onto the boss.

[0035] As a variant, the dispensing orifice can be configured to open onto a flat or substantially flat radial upper wall.

[0036] In the assembled position, the radial upper wall is in axial contact with, for example, the upper end of the container.

[0037] According to one embodiment, the reducer includes an inner skirt intended to be inserted into a second neck of the container in an assembled position, and an outer skirt that is connected to the inner skirt by a radially upper wall surrounding the inner skirt, and includes an inner cylindrical surface that carries a corresponding thread intended to mate with a second thread carried by the outer cylindrical surface of the second neck.

[0038] For example, the mounting skirt (in this case, the outer skirt) has a smaller axial dimension than the inner skirt.

[0039] Typically, the axial dimension of the mounting skirt (in this case, the outer skirt) is essentially equal to the axial dimension of the second neck of the container.

[0040] Advantageously, the inner skirt includes a sealing portion whose outer surface is in radial contact with the inner surface of the second neck of the container when in the assembled position.

[0041] For example, and in a completely non-limiting manner, the inner skirt includes an insert portion that extends axially from the sealing portion on the side opposite to the radial upper wall, and whose outer diameter is smaller than that of the sealing portion, so as to facilitate the insertion of the reducer into the opening of the container.

[0042] As a variation, the inner skirt may consist of only the sealed portion.

[0043] Advantageously, the mounting skirt (in this case, the outer skirt) includes a plurality of undulations on its outer surface, which are circumferentially distributed around the periphery of the outer surface, for example, regularly distributed. These undulations allow the user to easily manipulate the reducer to position it in the container and to loosen it relative to the container.

[0044] According to another embodiment, the mounting skirt is an inner skirt designed to be inserted into the second neck of the container in the assembled position. The mounting skirt includes an outer cylindrical surface that carries a corresponding thread designed to mate with a second thread carried by the inner cylindrical surface of the second neck.

[0045] Advantageously, the mounting skirt also includes an annular sealing protrusion that extends radially outward from the outer cylindrical surface of the mounting skirt and radially contacts the inner cylindrical surface of the second neck of the container when in the assembled position.

[0046] For example, the stepped neck of the container is connected to the body of the container via an annular collar, and the stepped neck is connected to the annular collar via a shoulder.

[0047] For example, the annular collar is connected to the body via a first joint so as to be radially offset inward relative to the body, and the neck is connected to the annular collar via a second joint (such as a shoulder) so as to be radially offset inward relative to the collar.

[0048] As a variant, the neck can be set to connect directly to the body of the container via the shoulder, without any intermediate ring.

[0049] The first joint has, for example, an inclined ramp. As a variation, the first joint can be a shoulder.

[0050] For example, the external thread carried by the first neck of the container includes a single threaded segment comprising a distal end and a proximal end, and the first neck of the container includes at least one stop on its outer surface for a screw end capped on the container.

[0051] The distal end is the end of the threaded segment of the external thread of the first neck that is closest to the far end of the container, and the proximal end is the end of the threaded segment of the external thread of the first neck that is closest to the second shoulder between the first neck and the annular collar.

[0052] The threaded segment forms a helix around the vertical line of sight on the outer surface of the first neck, between the distal end of the container and the proximal end of the first neck that connects to the second shoulder.

[0053] The external thread of the first neck has a twisting direction from the distal end of the first neck toward the proximal end.

[0054] As a variant, the neck of the container includes two pairs of screw-end stops extending radially outward from the outer surface of the first neck.

[0055] According to one embodiment, the screw-on end stop includes: a first protruding element that extends axially from a shoulder between a first neck and an annular collar toward a distal end of the container; and a second protruding element that extends axially from a proximal end of a threaded segment of an external thread of the first neck to the first protruding element.

[0056] For example, the first protruding element includes a stop surface, which is, for example, vertical, and forms a screw-on end stop or locking element for the cap.

[0057] For example, the second protruding element is in the form of an axial rib that extends axially along the vertical view axis from the first protruding element to the proximal end of the threaded segment of the external thread of the first neck. The axial rib forms a circumferential stop at the proximal end of each threaded segment of the tapped thread for the cap.

[0058] For example, the body of the container has a non-circular cross-section, while the stepped neck has a circular cross-section.

[0059] As a variation, the container body can have a circular or any other shaped cross section.

[0060] According to one embodiment, the cap includes an outer wall defined by an end and a radially upper wall, and a stepped inner wall conforming to the shape of a stepped neck of a container, the stepped inner wall being defined by an end wall provided with a sealing lip intended to contact the radially upper wall of a reducer in the assembled position. The stepped inner wall includes: a first cylindrical skirt radially surrounding a first engagement portion connecting a first neck to the body of the container; a second cylindrical skirt radially surrounding the first neck of the stepped neck of the container and including a first internal thread on its inner surface that mates with a first external thread carried by the first neck; and a third cylindrical skirt radially surrounding the second neck of the stepped neck of the container and the reducer in the assembled position. The outer diameter of the third cylindrical skirt is smaller than the inner diameter of the second cylindrical skirt of the cap's inner wall.

[0061] Therefore, a particularly compact axially compact packaging and dispensing assembly was obtained.

[0062] For example, the outer wall of the cap has a non-circular cross-section, while the inner wall of the cap has a circular cross-section. As a variation, the outer wall of the cap can have a circular or any other shaped cross-section.

[0063] Alternatively, the cap may have any other shape and include a cylindrical wall defined by an open end and a radial upper wall designed to axially contact the radial upper wall of the reducer directly or via a boss in the assembled position, the cylindrical wall including a first internal thread on its inner surface that mates with a first external thread carried by a first neck of the container. The cylindrical wall of the cap radially surrounds the entire reducer in the assembled position.

[0064] Hats can be made as a single piece or as multiple pieces that are fixed together.

[0065] For example, containers and caps can be made from any plastic material, using techniques such as injection stretch blow molding (ISBM), injection blow molding (IBM), extrusion molding (EBM), injection molding (IM), etc., especially from thermoplastic polymers such as polypropylene (PP), polyethylene (PE), or polybutylene terephthalate (PBT) or recycled plastic materials known by the abbreviation PCR or post-consumer recycled materials.

[0066] The reducer is preferably made in one piece by injection molding, for example, of a plastic material (e.g., a thermoplastic polymer, such as polyethylene (PE), or “PCR” recycled plastic material, or high-density polyethylene (HDPE), or polybutylene terephthalate (PBT), or any thermoplastic elastomer).

[0067] Further objects, features, and advantages of the invention will become apparent from the following description, given only by way of non-limiting example and with reference to the accompanying drawings, in which: [ Figure 1 ] An exploded perspective view of components for packaging and dispensing products according to an embodiment of the present invention is depicted. [ Figure 2 ] yes Figure 1 The front view of the packaging and dispensing components in the assembled position, with the cap offset relative to the container axis; [ Figure 2A ] yes Figure 1 A top view of the container of the component; [ Figure 3A ]and[ Figure 3B ] yes Figure 2 Partial views of the packaging and dispensing components in two vertical axial sections; [ Figure 4 ] yes Figure 1 A partial 3D view of the packaging and dispensing components without the cap; [ Figure 5 ]and[ Figure 6 ] yes Figure 1 A perspective view of the reducer itself, which is part of the packaging and dispensing components; and [ Figure 7 ] This is a partial view of the packaging and dispensing components according to another embodiment in an axial section.

[0068] The remainder of this specification will refer to the standard orthogonal system X, Y, Z, where Z corresponds to the vertical line of view or the extension axis, from which it can be seen that: - The longitudinal axis X, which is horizontal and Figure 2 The middle extends from left to right; - The horizontal axis Y, which is horizontal and perpendicular to the vertical axis X, and... Figure 2 The middle extends from front to back; and - Vertical axis Z, which is orthogonal to the longitudinal axis X and the transverse axis Y and Figure 2 It extends from the bottom to the top.

[0069] The terms "up" and "down" refer to the upper and lower parts of the image.

[0070] The terms “inner” or “internal” and “outer” or “external” are used to refer to the inside of product packaging and dispensing components, with the inner part or internal portion being closer to the vertical line of sight Z-Z' than the outer part or external portion.

[0071] Figure 1 Component 1 is shown for packaging and dispensing products, particularly cosmetic products.

[0072] "Product" is understood to be a liquid, semi-liquid, or viscous product intended to flow from a reservoir under the influence of gravity. In a completely non-limiting manner, a product can be a cosmetic product, such as a hygiene product or a personal care product.

[0073] Component 1 for packaging and dispensing products includes: a reservoir or container 10, a reducer 20 removably fastened to the container 10, and a cap or lid 30 removably fastened to the container 10.

[0074] Container 10 defines the internal volume V that contains the product.

[0075] In the exemplary embodiment shown in the accompanying drawings, the container 10 includes a body 11 that extends along an axial line Z-Z' assumed to be vertical in the drawings, and is provided with a closed lower end forming a bottom 12 and an open upper end 13 opposite to the lower end 12, the open upper end forming a stepped neck 14 and being provided with an opening O that allows access to an internal volume V for receiving a product.

[0076] As shown, in this case, the body 11 of container 10 has a non-circular cross-section, and the stepped neck 14 has a circular cross-section. As a variation, the body 11 of container 10 may have a circular or any other shaped cross-section.

[0077] In this case, the non-circular cross-section of the body 11 of the container 10 has an oval shape defined by a major axis A1 and a minor axis A2 that is at least 20% smaller than the major axis A1. Axes A1 and A2 are in... Figure 2A It is visible in the middle.

[0078] The stepped neck 14 includes a first neck 15, which is connected to the body 11 of the container 10 via an annular collar 16.

[0079] The annular collar 16 is connected to the body 11 via a first joint 11a so as to be radially offset toward the inside relative to the body 11, and the first neck 15 is connected to the annular collar 16 via a second joint 16a so as to be radially offset toward the inside relative to the collar 16.

[0080] As a variant, the first neck 15 can be configured to connect directly to the body 11 of the container 10 via the shoulder, without any intermediate annular collar.

[0081] "Joint" should be understood as the part used to connect two parts to each other.

[0082] In this case, the first joint 11a has an inclined ramp. As a variant, the first joint 11a can be configured as a shoulder.

[0083] In this case, the second joint 16a is a shoulder.

[0084] "Shoulder" is understood as any surface that is substantially perpendicular to the vertical viewing axis of the cylindrical component (in this case, the vertical viewing axis Z-Z' of container 10) resulting from a sudden change in diameter.

[0085] The first neck 15 extends around the vertical viewing axis Z-Z' and includes a first external thread 15b on its outer cylindrical surface 15a, which is intended to mate with a tapping thread or an internal thread 36b provided on the cap 30.

[0086] In this case, the first external thread 15b includes a single thread segment, which includes... Figure 1 and Figure 4 The distal 15c and proximal 15d are visible in the middle.

[0087] The distal end 15c is the end of the threaded segment of the external thread 15b closest to the distal end 13 of the container 10, and the proximal end 15d is the end of the threaded segment of the external thread 15b closest to the second shoulder 16a between the first neck 15 and the annular collar 16.

[0088] The threaded segment 15b forms a spiral around the vertical line of sight Z-Z' on the outer surface 15a of the first neck 15 between the distal end 13 of the container 10 and the proximal end of the first neck 15 connected to the second shoulder 16a.

[0089] The external thread 15b has a turning direction from the distal end 13 of the first neck 15 toward the proximal end.

[0090] As shown, the first neck 15 of the container 10 further includes two protruding elements 17a, 17b of the first pair 17 extending radially outward from the outer surface 15a of the first neck 15.

[0091] The first pair of protruding elements 17 form a stop for the screwing end of the cap 30 on the container 10.

[0092] The first pair of protruding elements 17 includes a first protruding element 17a extending axially from the second shoulder 16a toward the distal end 13 of the container 10 and a second protruding element 17b extending axially from the proximal end 15d of the threaded segment of the external thread 15b to the first protruding element 17a.

[0093] The first protruding element 17a includes a stop surface (not marked), which is vertical in this case and forms a screw-end stop or locking element of the cap 30.

[0094] The second protruding element 17b is in the form of an axial rib that extends axially from the first protruding element 17a along the vertical viewing axis Z-Z' to the proximal end 15c of the threaded segment of the external thread 15b.

[0095] Axial rib 17b forms a circumferential stop at each proximal end of the threaded segment of the tapping thread 36b for the cap 30.

[0096] As shown, the first neck 15 of the container 10 further includes a second pair of protruding elements 17c extending radially outward from the outer surface 15a of the first neck 15. The second pair of protruding elements 17c are located at 180° to the first pair 17 on the surface 15a of the first neck 15. The second pair of protruding elements 17c forms axial support for the cap 30 in the position where the container 10 is closed by the cap 30.

[0097] The stepped neck 14 further includes a second neck 18 connected to the first neck 15 via a second shoulder 19, such that it is radially offset inward relative to the first neck 15.

[0098] As shown, the second neck 18 extends directly from the first neck 15 along the vertical viewing axis Z-Z', with no intermediate elements between the two necks 15, 18.

[0099] The second neck 18 is radially defined by an outer cylindrical surface 18a and an inner cylindrical surface 18b.

[0100] Typically, the stepped neck 14 includes a stepped outer surface, which includes an outer surface 15a of a first neck 15 and an outer surface 18a of a second neck 18, the outer surfaces 15a and 18a being connected by a second shoulder 19.

[0101] As shown, the second neck 18 includes a second thread 18c on its outer cylindrical surface 18a, which is intended to mate with a tapping thread or an internal thread 25b provided on the reducer 20, and this second thread is external in this case.

[0102] The first thread 15b is axially and radially offset relative to the second thread 18c. In other words, the second thread 18c is axially located above the first thread 15b in the direction of the vertical viewing axis Z-Z', and the second thread 18c is positioned radially offset relative to the first thread 15b.

[0103] As a variant, such as Figure 5 As shown, the second neck 18 includes a second internal thread 18d on its inner cylindrical surface 18b, which is intended to mate with the external thread 21d provided on the reducer 20.

[0104] Typically, the threads 18c and 18d carried by the second neck 18 of the container 10 mate with the corresponding threads 25b and 21d carried by the mounting skirts 25 and 21 of the reducer 20, allowing the reducer 20 to be removably fastened to the container 10 by screwing. In other words, the axial retention of the reducer 20 on the container 10 is achieved through the engagement of the threads 18c, 18d, 25b, and 21d.

[0105] exist Figures 1 to 6 In the illustrated embodiment, the mounting skirt is the outer skirt 25, and... Figure 7 In the illustrated embodiment, the mounting skirt is an inner skirt 21.

[0106] As shown in the attached figure, the reducer 20 extends along the vertical line of sight Z-Z'.

[0107] The reducer 20 includes an inner skirt 21 intended to be inserted into a second neck 18 of the container 10 and defined by an open lower end 22, and a radial upper wall 23 provided with a dispensing orifice 24 for receiving products in the container 10.

[0108] The inner skirt 21 includes a sealing portion 21a, the outer surface 21b of which is... Figure 3A and Figure 3BThe visible assembly position is in radial contact with the inner surface 18b of the second neck 18 of the container 10. As shown, and in a completely non-limiting manner, the inner skirt 21 includes an insertion portion 21c that extends axially from the sealing portion 21a on the side opposite to the radial upper wall 23, and whose outer diameter is smaller than that of the sealing portion 21a, so as to facilitate the insertion of the reducer 20 into the opening O of the container 10. As a variation, the inner skirt 21 may include only the sealing portion 21a.

[0109] In the assembled position, the radial upper wall 23 is in axial contact with the upper end 13 of the container 10.

[0110] As shown, and in a completely non-limiting manner, the dispensing orifice 24 extends into the boss 23a, which projects axially outward from the radial upper wall 23. As a variation, the dispensing orifice 24 may be configured to extend into a flat or substantially flat radial upper wall 23.

[0111] The diameter of the distribution orifice 24 of the reducer 20 is smaller than the diameter of the opening O of the container 10.

[0112] Therefore, the reducer 20 is formed as a component for reducing the flow diameter of the product contained in the container 10.

[0113] like Figures 1 to 4 As shown, the reducer 20 includes an outer skirt 25 that extends axially downward from the lateral end of the radial upper wall 23 and radially surrounds the inner skirt 21.

[0114] In this configuration, the outer skirt 25 has a smaller axial dimension than the inner skirt 21. Typically, the axial dimension of the outer skirt 25 is substantially equal to the axial dimension of the second neck 18 of the container 10.

[0115] The outer skirt 25 includes an internal thread or tapping thread 25b on its inner surface (not marked) that mates with a thread 18c provided on the second neck 18 of the container 10.

[0116] In this case, the outer skirt 25 forms a skirt for mounting the reducer 20 on the container 10.

[0117] As shown, and in a completely non-limiting manner, the outer skirt 25 includes a plurality of undulations 26 (in this case, axial recesses) on its outer surface 25a, which are regularly distributed circumferentially around the periphery of the outer surface 25a. These undulations 26 allow the user to easily manipulate the reducer 20 to position it within the container 10 and to loosen it relative to the container 10. Other forms of undulations may be provided, such as multiple axial ribs.

[0118] The reducer 20 is placed on the container 10 by a twisting force or by an axial force on the reducer 20 toward the container 10, during which the threaded section of the internal thread 25b is snapped onto the threaded section of the external thread 18c of the second neck 18 of the container 10.

[0119] The reducer 20 is disassembled relative to the container 10 only by the rotational movement of the reducer 20 relative to the container 10, thereby loosening the reducer 20 relative to the container 10.

[0120] After loosening the reducer 20, the container 10 can be filled and reused when its internal volume V is empty.

[0121] The cap 30 is configured to close the distribution port 24 of the reducer 20 when in the assembled position.

[0122] As shown, in a completely non-limiting manner, the cap 30 extends along a vertical viewing axis assumed to be vertical in the figures and includes an outer wall 31 (in this case, a non-circular cross-section) defined by a closed lower end 32 and a radial upper wall 33 intended to be above the radial upper wall 23 of the reducer 20 in the assembled position.

[0123] In this case, the cap 30 is made of two pieces that are fixed to each other.

[0124] As a variant, the cap 30 can be made as a single piece.

[0125] As a variation, a cylindrical cap can also be provided.

[0126] The cap further includes an inner wall 34 connected to the lower wall 32.

[0127] The inner wall 34 of the cap 30 is shaped to match the stepped neck 14 of the container 10.

[0128] The inner wall 34 of the cap 30 includes, along the extending axis Z-Z', the following in sequence: a first cylindrical skirt 35 that radially surrounds the annular collar 16 of the container 10; a second cylindrical skirt 36 that radially surrounds the first neck 15 of the stepped neck 14; and a third cylindrical skirt 37 that surrounds the second neck 18 of the stepped neck 14, particularly the outer skirt 25 of the reducer 30.

[0129] The skirts 35, 36, and 37 are connected by corresponding shoulders (not marked) to form a stepped skirt on the side opposite to the container 10, the outer diameter of which gradually decreases along the extension axis.

[0130] The second cylindrical skirt 36 includes an internal thread or tapping thread 36b on its inner surface 36a that mates with the external thread 15b carried by the first neck 15 of the container 10.

[0131] When in the assembled position, the inner wall 34 of the cap 30 radially surrounds the entire reducer 20.

[0132] As shown, the cap 30 further includes an end wall 38 that extends radially at the upper end of the third cylindrical skirt 37 and is axially positioned above the reducer 20 in the assembled position.

[0133] The end wall 38 includes an annular sealing lip 38a that extends from the lower surface of the end wall 38 toward the reducer 20 in an inwardly inclined direction.

[0134] The sealing lip 38 is designed to contact the upper wall 23 in the assembled position and ensure a seal of component 1.

[0135] The same elements have the same reference numerals. Figure 7 In the example shown, the reducer 20 includes a single skirt 21 extending between the opening 22 and the radial upper wall 23.

[0136] The skirt 21 includes an external thread 21d on its outer cylindrical surface 21b, which is intended to mate with a second thread 18d provided on the inner cylindrical surface 18b of the second neck 18 of the container 10.

[0137] The skirt 21 further includes an annular sealing protrusion 21e that extends radially outward from the outer cylindrical surface 21b of the skirt 21 and, in the assembled position, radially contacts the inner cylindrical surface 18b of the second neck 18 of the container 10.

[0138] In this embodiment, the inner skirt 21 forms a skirt for mounting the reducer 20 onto the container 10.

[0139] In all embodiments, container 10 and cap 30 may be made of plastic materials, particularly thermoplastic polymers such as polypropylene (PP), polyethylene (PE) or polybutylene terephthalate (PBT) or recycled plastic materials known as abbreviated PCR or post-consumer recycled materials.

[0140] The reducer 20 is made in one piece, for example, by injection molding of a plastic material, such as a thermoplastic polymer, like polyethylene (PE), or “PCR” recycled plastic material, or high-density polyethylene (HDPE), or polybutylene terephthalate (PBT), or any thermoplastic elastomer.

[0141] With the various arrangements of the present invention, the Company is able to provide its customers with cosmetic product packaging and dispensing components 1, which include a removable reducer with a minimal structure, while ensuring good axial retention and sealing, thereby reducing the environmental impact of the manufacture of such components (in particular by limiting the raw materials used), the impact of their packaging and transportation (in particular by limiting the quality of the components), or the impact of their end-of-life disposal.
