Description

Description Title of the invention: Device for dispensing and applying a cosmetic product in solid form Technical Field

[0001] The invention relates to the field of devices for dispensing and applying cosmetic products (also called cosmetic applicators), and more particularly products in solid form, especially in the form of sticks, such as lipsticks or deodorants. State of the art

[0002] We know of cosmetic product applicators, such as lipstick, lip product, or deodorant applicators, comprising a base and a cap, the base incorporating a mechanism operated by rotation of a part of the base and allowing the cosmetic product to be dispensed so that a user can apply it to a part of their body.

[0003] Traditionally, the materials used to manufacture such an applicator are metal and / or plastic.

[0004] However, in order to reduce the amount of plastic used, it is known to manufacture applicators at least partially from paper or cardboard. International application number WO 2023 / 247904 describes an applicator in which the base and cover are made from paper, while the mechanism itself is made of plastic.

[0005] To further reduce the amount of plastic used, it is known to manufacture applicators made entirely of cardboard without a rotating mechanism.

[0006] However, no applicator with a rotating mechanism, which allows for the preservation of an elaborate gesture appreciated by users, is known to be made entirely from a paper material.

[0007] The objective of the present invention is to meet this need by providing an applicator incorporating a rotating mechanism that can be made entirely from a paper material, and that is easy to manufacture. Description of the invention

[0008] For this purpose, the invention relates to a device for applying a cosmetic product in solid form, the application device comprising a base, a receptacle for a product and a sheath arranged around the receptacle; the sheath and the receptacle being mobile relative to each other in a helical motion around a central axis of the application device, between a first position of the receptacle relative to the sheath, or low position, and a second position of the receptacle relative to the sheath, or high position, the sheath being integral with a female threaded organ cooperating with a male threaded organ fixed in rotation relative to the base; the male threaded part and the female threaded part being made from a paper material; the application device being such that: - the male threaded organ comprises an internal structure of generally tubular shape and one or more external threaded elements attached to the internal structure, the external threaded element or elements forming at least partially an external thread; - the female threaded organ comprises an external structure of generally tubular shape and one or more internal threaded elements attached to the external structure, the internal threaded element or elements forming at least partially an internal thread.

[0009] Thus, by providing threaded elements (male and female) made of at least two parts—at least a first structural part with a simplified shape, and at least a second part forming a thread—it is possible to design the second part(s) with a reduced thickness, which simplifies their manufacture from paper material, particularly by facilitating their shaping. The invention therefore makes it possible to create a cosmetic product application device comprising a rotating mechanism made entirely from paper material.

[0010] The application device according to the invention may include one or more of the following optional features, considered alone or in all possible combinations.

[0011] According to one characteristic, the male threaded organ has a single added external threaded element, the external threaded element being configured to cover between 50% and 100% of the external circumference of the internal structure.

[0012] According to one characteristic, the female threaded organ has a single internal threaded element, the internal threaded element being configured to cover between 50% and 100% of the internal circumference of the external structure.

[0013] According to one characteristic, the male threaded organ has at least two external threaded elements attached, each external threaded element being configured to cover between 20 and 50% of the external circumference of the internal structure.

[0014] According to one characteristic, the female threaded organ has at least two internal threaded elements attached, each internal threaded element being configured to cover between 20 and 50% of the internal circumference of the external structure.

[0015] According to one characteristic, the male threaded organ has three or four external threaded elements attached, each external threaded element being configured to cover respectively between 15 and 33% or between 10 and 25% of the external circumference of the internal structure.

[0016] According to one characteristic, the female threaded organ has three or four internal threaded elements attached, each internal threaded element being configured to cover respectively between 15 and 33% or between 10 and 25% of the internal circumference of the external structure.

[0017] According to one characteristic, the external structure of the female threaded organ is fixed to the sheath.

[0018] According to one characteristic, the external structure of the female threaded organ is formed by the sheath.

[0019] According to one characteristic, the receptacle is fixed to the internal structure of the male threaded organ, preferably by gluing.

[0020] According to one characteristic, a support is integral with the internal structure of the male threaded organ, the support being integral with the base.

[0021] Depending on a characteristic, the external threaded element(s) is fixed to the internal structure by gluing.

[0022] According to a characteristic, the internal threaded element(s) is fixed to the external structure by gluing.

[0023] According to one characteristic, the receptacle is fixed relative to the base, while the sheath is mobile relative to the base.

[0024] According to one feature, the application device includes stop stops to block the rotation of the female threaded part when the receptacle reaches one of the high and low positions.

[0025] According to one characteristic, the receptacle is mobile in translation relative to the base, the sheath being mobile in rotation relative to the base.

[0026] According to one characteristic, the base comprises a generally tubular sleeve, the sleeve being interposed between the internal structure of the male threaded member and the sheath, the sleeve having at least one window extending in an axial direction, the male threaded member having a threaded element disposed opposite the window or each window, the external threaded element(s) extending at least partially through the corresponding window.

[0027] According to one characteristic, the base, the receptacle and the sheath are made from a paper material.

[0028] According to one feature, the application device includes a cover that can be removably attached to the base, the cover being made from a paper material. Brief description of the drawings

[0052] Figures 1 and 2 show an application device 1 according to the invention, viewed respectively in perspective and in section. The application device 1 is configured to contain a product P in solid form, and in particular a cosmetic product such as a deodorant, a lip product (balm, lipstick, etc.), or other.

[0053] The application device 1 comprises a base 10 and a cover 30 that can be removably attached to the base. The base 10 includes a receptacle 12 configured to support and hold the product P. In the example shown in the figures, the receptacle 12 is a cup, but it could be, for example, a tray. In this description, the terms "up" and "down" refer to the normal orientation of the application device, in which the free end of the product P is oriented upwards.

[0054] The application device 10 has a general shape that is symmetrical with respect to a central axis X, in the example a symmetrical shape of revolution.

[0055] The base 10 comprises a tubular sheath 14, arranged around the receptacle 12. The receptacle 12 and the sheath 14 are configured to allow relative movement of the receptacle 12 with respect to the sheath 14 between a low position of the receptacle 12 (with respect to the sheath 14), visible in Figure 11, and a high position of the receptacle 12 (with respect to the sheath 14), visible in Figure 2. In the low position of the receptacle 12, the product P is located partially or entirely within the sheath 14, which allows the product P to be concealed and protected. In the high position of the receptacle 12, the product P is located at least partially outside the sheath, so as to allow its application.Of course, depending on the quantity of product P remaining, the height of the product being reduced as it is used, it becomes possible to keep the product P respectively in and out of the sheath 14 in intermediate positions of the receptacle 12 relative to the sheath 14.

[0056] The relative motion of the receptacle 12 with respect to the sheath 14 is a helical motion around the central axis X. It can be achieved in several ways. In the example of Figures 1 to 11, the sheath 14 is mobile with respect to the base 10, while the receptacle 12 is fixed with respect to the base 10.

[0057] In this first example, the sheath 14 is movable relative to the base 10, and therefore relative to the receptacle 12, in a helical motion with its axis coinciding with the central axis X of the application device 1. For this purpose, a male threaded element 16 (i.e., an element having an external thread) is fixed to the receptacle 12, and therefore to the base 10. The male threaded element 16 is fixed relative to the base 10. The male threaded element 16 cooperates with a female threaded element 18 (i.e., an element having an internal thread) fixed to the sheath 14. The female threaded element 16 is fixed relative to the sheath 14.

[0058] According to the invention, each of the threaded elements 16, 18 is made of at least two assembled parts, namely a first part forming the structure of the corresponding threaded element 16, 18, and at least a second part forming a thread or a portion of a thread. Manufacturing the threaded elements 16, 18 by assembling a structural part and at least one functional part makes it possible to produce these elements entirely from a paper material. Indeed, it is possible to provide a structural part sufficiently thick to obtain the required rigidity, and to provide the second part(s) with a thinner profile, thus facilitating the manufacturing of the threading components by molding or forming.

[0059] In the example, as can be seen in particular in Figure 3, the male threaded member 16 comprises, on the one hand, an internal structure 160, of a generally symmetrical shape of revolution around the central axis X, and, on the other hand, one or more external threaded elements 162 attached to the internal structure 160. Similarly, the female threaded member 18 comprises, on the one hand, an external structure 180, of a generally symmetrical shape of revolution around the central axis X, and, on the other hand, one or more internal threaded elements 182 attached to the external structure 180 (see in particular Figures 7 and 8).

[0060] As shown in Figure 4, the internal structure 160 of the male threaded member 16 has a generally tubular shape centered around the central axis X (when the application device 1 is assembled). In the example shown in Figures 1 to 11, the male threaded member 16 has two attached external threaded elements 162. Regardless of their number, the external threaded elements 162 are preferably attached to the internal structure 160 by bonding.

[0061] As can be seen in Figures 5 and 6, each external threaded element 162 comprises a shell 164 forming a portion of a tube. Each shell 164 has an internal surface 164a, intended to be attached to an external surface 160a of the internal structure 160, and an external surface 164b, on which thread segments 166 are formed. The thread segments 166 extend helically around the central axis X, and are arranged along an axis parallel to the central axis X, such that the thread segments 166 are all arranged along the same helix with an axis coinciding with the central axis X.

[0062] When the threaded elements 162 are assembled on the internal structure 160, the thread segments 166 cooperate together to form a functional thread, i.e., one capable of cooperating with a compatible female thread, and in particular the thread of the female threaded member 18. In the example of Figures 1 to 11, each external threaded element 162 extends over 50% of the (external) circumference of the internal structure 160. However, it could be envisaged that each external threaded element 162 extends over a smaller portion of the circumference of the internal structure 160, and for example between 20% and 50%. Each threaded segment 166 preferably extends over a majority portion or over the entire contour of the external surface 164b of the shell 164 of the corresponding threaded element 162, and in particular over at least 75% of this contour, for example over 80% to 100% of this contour.

[0063] As shown in Figure 7, the external structure 180 of the female threaded member 18 has a generally tubular shape centered around the central axis X (when the application device 1 is assembled). In the example shown in Figures 1 to 11, the female threaded member 18 has two attached internal threaded elements 182. Regardless of their number, the internal threaded elements 182 are preferably attached to the external structure 180 by bonding. The external structure 180 is located within the sheath 14, at its lower end. The external structure 180 is attached to the sheath 14, and more specifically to the internal surface 14a of the sheath 14, preferably by bonding. In an unrepresented variant, the external structure 180 is formed directly by the sheath 14. In this case, the internal threaded elements 182 are attached directly to the sheath 14, and are fixed to the internal surface 14a of the sheath 14, preferably by bonding.

[0064] As shown in Figure 8, each internally threaded element 182 comprises a shell 184 forming a portion of a tube. Each shell 184 has an external surface 184a, intended to be attached to an internal surface 180a of the external structure 180 (see Figure 11), and an internal surface 184b, on which adjacent thread segments 186 are formed. The thread segments 186 extend helically around the central axis X and are arranged along an axis parallel to the central axis X, such that the thread segments 186 are all arranged along the same helix whose axis coincides with the central axis X.

[0065] When the internal threaded elements 182 are assembled on the external structure 180, the thread segments 186 cooperate together to form a functional thread, i.e., one capable of cooperating with a compatible male thread, and in particular the thread of the male threaded member 16. In the example of Figures 1 to 11, each internal threaded element 182 extends over 50% of the (internal) circumference of the external structure 180. However, it could be envisaged that each internal threaded element 182 extends over a smaller portion of the circumference of the external structure 180, for example between 20% and 50%.

[0066] When the application device 1 is assembled, as shown in Figures 1 and 11, the sheath 14 is fixed to the female threaded member 18. The sheath 14 is located within the base 10. The base 10 has, at a first end, or lower end 10a, a bottom 100. The base has a tubular casing 102 extending along the central axis X from the bottom 100, the tubular casing 102 surrounding the sheath 14 over part of its height (along the central axis X). Since the sheath 14 is movable relative to the base 10, the sheath 14 is movable relative to the tubular casing 102. In the example, the base 10 also has an external tubular casing 104 surrounding the tubular casing 102 over part of its height. The upper end 104a of the outer casing 104 forms with the tubular casing 102 a shoulder forming a stop for the arrangement of the hood 30.

[0067] The receptacle 12 is fixed to the male threaded organ 16, which is itself fixed to the base 10. The receptacle 12 is fixed relative to the male threaded organ 16 and the male threaded organ 16 is fixed relative to the base 10.

[0068] In the example shown in Figures 1 to 11, the receptacle 12 is fixed, notably by bonding, to the internal structure 160 of the male threaded member 16. For this purpose, as can be seen in Figure 9, the receptacle 12 comprises a receiving portion 120 and a fixing portion 122, both generally symmetrical in shape around the central axis X (when the application device 1 is assembled). In the example shown in the figures, the receptacle 12 being a cup, the receiving portion 120 is hollow and defines an open cavity 120a for receiving a portion of a product P. The receiving portion 120 can, however, be configured differently, for example, to form a tray. The fixing portion 122 has a shape and dimensions compatible with its insertion into the internal structure 160, at its upper end.The attachment of the receptacle 12 to the internal structure 160 is achieved in the example by gluing the attachment part 122 onto the internal surface 160b of the internal structure 160.

[0069] At its lower end, the internal structure 160 is attached to a support 20. As shown in Figure 10, the support 20 comprises a base 200 and a fastening portion 202, both generally symmetrical in shape and of revolution around the central axis X (when the application device 1 is assembled). The fastening portion 202 has a shape and dimensions compatible with its insertion into the internal structure 160. In this example, the internal structure 160 is attached to the support 20 by bonding the fastening portion 202 to the internal surface 160b of the internal structure 160.

[0070] The support 20 is fixed to the bottom 100 of the base 10, preferably by gluing.

[0071] As can be seen in Figures 2 and 11, the sheath 14 and the receptacle 12 form a screw / nut system via the threaded members 16, 18. Since the receptacle 12 is fixed relative to the base 10, rotating the sheath 14 relative to the base 10 will cause the sheath 14 to move helically around the central axis X, and thus move the sheath 14 between the upper position (Figure 2) and the lower position (Figure 11), or vice versa.

[0072] To rotate the duct 14, the user can grasp the base 10 with one hand and rotate the duct 14 with the other. For this purpose, the application device 1 is configured so that the duct 14 remains accessible to the user even when it is in the lowered position. Specifically, the height of the duct 14 (measured along the central axis X, from the bottom 100 of the base) is greater than the height of the tubular casing 102, so that in the lowered position, the duct 14 is not completely concealed by the tubular casing 102.

[0073] Advantageously, the application device 1 includes stop stops to limit the rotation range of the duct 14. Preferably, at least one lower stop stop is provided, allowing the duct 14 to be blocked when it reaches the lower position, and at least one upper stop stop, allowing the duct 14 to be blocked when it reaches the upper position.

[0074] In the example shown in Figures 1 to 11, the application device 1 includes two upper stop stops 124 formed on the receptacle 12, and more specifically on the mounting portion 122 of the receptacle 12. The application device 1 also includes two lower stop stops 204 formed on the support 20, and more specifically on the mounting portion 202 of the support 20. As can be seen in particular in Figures 9 and 10, the stop stops 124, 204 are projections extending radially from an external surface of the corresponding mounting portion 122, 202 about the central axis X. These projections prevent the rotation of the female threaded member 18 when its threads come into contact with one of the stop stops 124, 204.Providing stop blocks 124, 204 to prevent rotation of the female threaded part 18 is preferable to an axial stop, which would only prevent axial movement of the female threaded part 18. Indeed, with an axial stop, if a user were to force the mechanism once the stop was reached, there would be a risk that this action could cause some of the components of the application device 1 to become detached. To allow the insertion of the fastening part 122, 202 equipped with the corresponding stop blocks 124, 204, additional shaped notches are provided in the male threaded part 16. In the example, notches 160c are provided at the upper and lower ends of the internal structure 160. If necessary, notches 162a are also provided on the external threaded elements 162.

[0075] Figures 12 to 20 illustrate a variant of the application device shown in Figures 1 to 11. In this example, the receptacle 12 is not fixed relative to the base 10, but is movable relative to it, between a low and a high position. More precisely, the sheath 14 is movable relative to the base 10, but only in rotation about the central axis X, while the receptacle 12 is movable relative to the base 10, but only in translation along the central axis X.

[0076] As in the example of figures 1 to 11, the receptacle 12 is integral with a male threaded organ 16 and the sheath 14 is integral with a female threaded organ 18.

[0077] The receptacle 12 is fixed to the internal structure 160 of the male threaded member 16 by means of the fixing portion 122, visible in particular in Figure 19. However, in order to allow translational movement of the receptacle 12 relative to the base 10, the base 10 has a sleeve 22 of generally tubular shape centered around the central axis X and arranged around the external structure 160 of the male threaded member 16. The sleeve 22 is fixed relative to the base 10, being, in this example, fixed to the support 20 of Figure 20. The sleeve 22 is configured so that the external structure 160 of the male threaded member 16 can slide inside the sleeve 22 along the central axis X. The sleeve 22 has at least one window 220; in this example, two diametrically opposed windows 220.Each window 220 is configured so that a part of an external threaded element 162 of the male threaded organ 160 can extend radially, from the internal structure 160, through the corresponding window 220. Thus, a portion of one or more threaded elements 162 of the male threaded member 16 extends through the corresponding window 220 to cooperate with the female threaded member 18. Furthermore, each window 220 is configured to prevent rotation of the corresponding external threaded element 162 and to allow sliding movement of the corresponding external threaded element 162 along the central axis X. Therefore, with the sleeve 22 fixed relative to the base 10, the cooperation between the window(s) 220 of the sleeve 22 and the threaded elements 162 of the male threaded member 16 prevents rotation of the receptacle 12 relative to the base 10, while allowing translational movement of the receptacle 12 along the central axis X.

[0078] We have seen that the receptacle 12 is movable relative to the base 10 only in translation along the X-axis, while the sheath 14 is movable relative to the base 10 only in rotation. As in the example of Figures 1 to 11, the sheath 14 and the receptacle 12 form a screw / nut system via the threaded members 16 and 18. However, in the example of Figures 12 to 20, since the receptacle 12 is movable in translation relative to the base 10, rotating the sheath 14 relative to the base 10 will cause the receptacle 12 to move in translation along the central X-axis, and thus move the receptacle 12 relative to the base 10, and therefore relative to the sheath 14, between the lower and upper positions, or vice versa.

[0079] As can be seen in Figures 12, 13, 17, and 18, the male threaded member 16 has an internal structure 160 similar to that described previously, and, in the example, two external threaded elements 162 similar to those described above. Each external threaded element 162 thus comprises a shell 164 forming a portion of a tube and thread segments 166 formed on the external surface 164a of the shell 164. Unlike the external threaded elements 162 described previously, the thread segments 166 are here formed on a boss 164c formed on the external surface 164a of the shell 164. The boss 164c forms a protrusion intended to contact and bear against the edge of the corresponding window 220 of the sleeve 22. Preferably, the thickness of the boss 164c is greater than or equal to the thickness of the sleeve 22.

[0080] As can be seen in Figures 12, 13, 15 and 16, the external structure 180 of the female threaded member 18 is identical to the sheath 14. The internal threaded elements 182, which are similar to those described above, are therefore attached directly to the internal surface 14a of the sheath 14. Advantageously, in order to facilitate the positioning of each internal threaded element 182 during the assembly of the application device 1, each shell 184 has a tab 184c intended to bear against the lower end of the sheath 14.

[0081] In the example shown in Figures 12 to 20, the translational movement of the receptacle 12 is limited in the upper position by the upper end of the windows 220, which restrict the travel of the corresponding external threaded elements 162. The translational movement of the receptacle 12 is limited in the lower position by the support 20, whose base 200 forms an axial stop that blocks the threaded elements 162. Alternatively, stops could be provided to block the rotation of the threaded elements 162 in the lower position of the receptacle 12, for example, stops extending radially inward from the threaded elements 182, or from the external structure 180, or from the sheath 14.

[0082] In the example, the sleeve 22 has at its upper end a rim 222. The rim 222 extends radially outwards and is configured to form a stop preventing any axial movement of the internal threaded elements 182.

[0083] The components of the application device 1 according to the invention are preferably all made from a paper material and, where appropriate, assembled by gluing. In particular, the components having a generally tubular shape, such as the cover 30, the outer casing 104, the tubular casing 102, the sheath 14, the sleeve 22, the internal structure 160, and the external structure 180, can be made by shaping sheets of cardboard or paper. The paper sheets can have a surface mass of between 70 g / m² 2 and at 200 g / m 2 Cardboard sheets can have a surface mass of between 200 g / m² 2 and 500 g / m 2 .

[0084] Elements with complex shapes, such as the receptacle 12, the support 20, the external threaded elements 162 and the internal threaded elements 182, can be made by molding or forming a paper material, for example from paper pulp.

[0085] With regard to the external threaded elements 162 and internal threaded elements 182, as shown in Figure 21, which represents a partial radial cross-sectional view of an external threaded element 162, the shape and dimensions of the thread segments 166, 186 forming the thread are preferably designed to facilitate manufacturing, and in particular the demolding of the external threaded elements 162 and internal threaded elements 182. For example, the thread pitch p is preferably greater than or equal to 2 mm, and for example greater than or equal to 3 mm. The thread height h is for example less than or equal to 1.5 mm, preferably less than or equal to 1 mm, and for example equal to approximately 0.8 mm. Furthermore, the radius of curvature R of the crests is greater than or equal to 0.5 mm, and preferably greater than or equal to 0.7 mm, and for example equal to approximately 0.8 mm.

[0086] Figures 22 and 23 show examples of embodiments of the male threaded organ 16.
