Description

Technical Field

[0001] This invention relates to an apparatus for storing and dispensing at least two cosmetic products, the apparatus comprising:

[0002] - A container, comprising at least a first receiving portion and a second receiving portion, the first receiving portion being configured to receive a first cosmetic product and the second receiving portion being configured to receive a second cosmetic product;

[0003] - A first dispenser, the first dispenser includes a first pump, a first movable rod and a first sampling tube, the first pump extends along the first pump axis and the first sampling tube is immersed in a first receiving portion;

[0004] - A second dispenser, comprising a second pump, a second movable rod, and a second sampling tube, wherein the second pump extends along a second pump axis parallel to the axis of the first pump, and the second sampling tube is immersed in a second receiving portion;

[0005] - A dispensing nozzle, connected to a first movable rod and a second movable rod, the dispensing nozzle including at least one conduit for dispensing a first cosmetic product and a second cosmetic product, the nozzle being movable relative to the container between a rest position and a dispensing position, the nozzle including a pressing surface and a guide wall extending from the pressing surface toward the container.

[0006] The device is configured to deliver at least two cosmetic products so that a mixture of the two products is formed before the user applies them to the body surface.

[0007] A mixture of at least two cosmetic products, such as skincare products, cosmetic products, and / or hair dye products.

[0008] More generally, cosmetic products are products that involve cosmetics as defined in EU Regulation No. 1223 / 2009 issued by the European Parliament and the Commission on 30 November 2009. Background Technology

[0009] Some blends of cosmetic products (such as in the realm of 3-in-1 total care products) are unstable for a certain period of time and therefore only possess activity for a limited duration. This is, for example, when a comprehensive whitening care product is mixed with a deep whitening product, an antioxidant product, and an outer layer of color correcting and protective products.

[0010] Some mixtures have a viscosity higher than that of each cosmetic product used to prepare the mixture. The viscosity of the mixture is so high that it cannot flow properly in the dispensing channels.

[0011] In this situation, the mixture cannot be stored in a single container of the dispensing device. The cosmetic products are individually packaged, and the mixture is prepared directly in a separate accessory.

[0012] In addition, both products should typically be delivered simultaneously from a single nozzle pressed by the user in a predetermined ratio.

[0013] When only one nozzle dispenses two products, the first dispenser associated with the first receiving section and the second dispenser associated with the second receiving section are quite far apart. There is a risk of nozzle pressure imbalance, which will result in products being delivered in a different ratio than intended. Summary of the Invention

[0014] Therefore, one object of the present invention is to provide an easy-to-use device for storing two cosmetic products, which enables the efficient dispensing of the cosmetic products.

[0015] For this purpose, the subject of the present invention is a device of the type described above, characterized in that the device further includes a guide support mounted on the container between the container and the nozzle, the guide support including an inner guide portion and an outer guide portion defining an intermediate guide space, the guide wall of the nozzle being guided within the intermediate guide space by the inner guide portion and the outer guide portion, such that the nozzle is displaced parallel to the first pump axis and the second pump axis between a rest position and a dispensing position.

[0016] This guide support allows for the dispensing of two cosmetic products while preventing imbalance when the dispensing nozzle is pressed towards the container. The fit between the guide wall and the intermediate guide space allows the nozzle to move with precise height, parallel to the axes of the first and second pumps.

[0017] In one variation, the nozzle guide wall slides on the inner and outer guide portions between a rest position and a dispensing position.

[0018] The sliding of the guide wall on the inner and outer guide portions allows for smooth and precise guidance of the nozzle between the rest position and the distribution position.

[0019] In one variation, the inner guide portion includes two collars, each movable rod being guided between a rest position and a distributive position by one collar.

[0020] The two collars enable precise guidance of the first and second movable rods between the rest position and the assigned position.

[0021] In one variation, the guide support further includes a connecting portion that connects the inner guide portion and the outer guide portion, with an intermediate guide space defined between the inner guide portion, the outer guide portion, and the connecting portion.

[0022] In another variation, the inner guide portion includes at least one inner sleeve, the outer guide portion includes at least one outer sleeve, and the engagement portion includes at least one annular engagement portion connecting at least one inner sleeve and at least one outer sleeve, with an intermediate guide space defined between at least one outer sleeve, at least one inner sleeve, and at least one annular engagement portion.

[0023] The joining section enhances the stability of the guide support. The inner and outer guide sections are connected by the joining section, which simplifies the assembly of the guide support onto the container.

[0024] In one variation, the intermediate guide space complements the guide wall of the nozzle, allowing the nozzle to shift between a rest position and a distribution position according to a single degree of freedom, which corresponds to a translation component parallel to the axes of the first and second pumps.

[0025] The intermediate guide space and guide wall complement each other, allowing for the restriction of any movement of the nozzle except for movement parallel to the axes of the first and second pumps. Therefore, each movable rod shifts simultaneously and identically between its rest position and its dispensing position.

[0026] In one variation, the outer guide portion includes two outer sleeves and an outer intermediate connecting region between the outer sleeves. The outer intermediate connecting region defines at least a portion of the intermediate guide space outward, and the outer intermediate connecting region protrudes toward a plane including the first pump axis and the second pump axis.

[0027] And / or, the inner guide portion includes two inner sleeves and an inner intermediate connecting region between the inner sleeves, the inner intermediate connecting region having a recess extending toward a plane including the first pump axis and the second pump axis, the inner intermediate connecting region defining at least a portion of an intermediate guide space inward, and the guide wall also being guided in the intermediate guide space between a rest position and a dispensing position by the inner intermediate connecting region and / or by the outer intermediate connecting region.

[0028] In another variation, the minimum width of the projection of the inner intermediate connecting region onto the projection plane is less than the maximum width of each inner sleeve, and the projection plane is perpendicular to the first pump axis and the second pump axis.

[0029] The inner and outer intermediate connecting regions allow for further improvement in nozzle guidance by further restricting the guide space. Due to the intermediate connecting regions, the geometry of the guide space is optimal for guiding the nozzle along a single degree of freedom.

[0030] In one variation, the inner guide portion includes radial fins projecting radially outward from the inner sleeve or each inner sleeve, with an intermediate guide space defined between the radial fins and the outer sleeve or each outer sleeve.

[0031] The radial fins further restrict the guide space. Therefore, the intermediate guide space extends between the fin edges and the outer sleeve. Nozzle guidance is further improved, while the structure remains lightweight.

[0032] In one variation, the inner sleeve or each inner sleeve has a generally circular cross-section projected onto a projection plane perpendicular to the first pump axis and the second pump axis, and / or the outer sleeve or each outer sleeve has a generally arcuate cross-section projected onto the projection plane.

[0033] The circular shape of the inner sleeve or each inner sleeve and / or the arcuate shape of the outer sleeve or each outer sleeve causes the intermediate guide space to bend. This enables effective nozzle guidance while optimizing the compactness of the equipment.

[0034] In one variation, the nozzle includes a first dispensing conduit for dispensing a first cosmetic product and a second dispensing conduit for dispensing a second cosmetic product, each conduit being connected to a corresponding movable rod.

[0035] In another variation, each movable rod includes an annular groove, and a first and second dispensing conduit each include a tubular wall defining a flow path, through which the corresponding cosmetic product is designed to flow, each tubular wall extending within the annular groove of the rod.

[0036] Each movable rod is securely connected to its corresponding distribution conduit. This further enhances the stability of the equipment.

[0037] The present invention also relates to a method for dispensing at least two cosmetic products, the method comprising:

[0038] - Provide the equipment as described above;

[0039] - To move the nozzle between the rest position and the dispensing position; and

[0040] - The first and second cosmetic products are delivered simultaneously through at least one conduit. The nozzle guide wall is guided by an inner guide portion and an outer guide portion within an intermediate guide space, such that the nozzle is displaced parallel to the first and second pump axes between a rest position and a dispensing position.

[0045] exist Figures 1 to 3 The image shows an apparatus 10 for storing and dispensing at least two cosmetic products designed to form a cosmetic composition.

[0046] Cosmetic compositions are, for example, compositions for treating body surfaces, compositions for applying makeup to body surfaces, or preferably compositions for coloring a user's keratin fibers (especially the user's hair).

[0047] To form a cosmetic composition, at least two cosmetic products are mixed.

[0048] Cosmetic products are those defined, for example, in EU Regulation No. 1223 / 2009 issued by the European Parliament and the Commission on 30 November 2009.

[0049] Device 10 extends along the longitudinal axis X-X', which is vertical.

[0050] The device 10 includes a container 12, a first dispenser 14, a second dispenser 16, a dispensing nozzle 18, and a guide support 20.

[0051] Container 12 is configured to contain a first cosmetic product and a second cosmetic product.

[0052] The container 12 includes at least a first receiving portion 24 and a second receiving portion 26, the first receiving portion being configured to receive a first cosmetic product and the second receiving portion being configured to receive a second cosmetic product.

[0053] The first dispenser 14 includes a first pump 30, a first movable rod 32, and a first sampling tube 34.

[0054] The first pump 30 extends along the first pump axis A-A'. The first pump axis A-A' is parallel to the longitudinal axis X-X'.

[0055] A first movable rod 32 connects a first pump 30 to a dispensing nozzle 18. The first movable rod 32 is a movable hollow rod portion that controls the actuation of the first pump 30. The first movable rod includes a first product outlet 68 located at its top end and a first annular groove 70. The outlet 68 is inserted into the nozzle 18. The first annular groove 70 extends around the first product outlet 68 at the top end of the rod 32. As will be described below, the nozzle 18 extends within the first annular groove 70 such that the nozzle 18 is connected to the rod 32. Displacement of the rod 32 parallel to the first pump axis A-A' enables the dispensing of a first cosmetic product from the first sampling tube 34 to the first product outlet 68 via the first pump 30.

[0056] The first sampling tube 34 is installed upstream of the first pump 30 and protrudes downward from the first pump 30. The first sampling tube is immersed in the first receiving portion 24 to sample the first cosmetic product in the first receiving portion 24.

[0057] The second dispenser 16 is similar to the first dispenser 14. For example, the second dispenser 16 is structurally identical to the first dispenser 14. The second dispenser 16 includes a second pump 40, a second movable rod 42, and a second sampling tube 44.

[0058] The second pump 40 extends along the second pump axis B-B'. The second pump axis B-B' is parallel to the longitudinal axis X-X' and parallel to the first pump axis A-A'.

[0059] A second movable rod 42 connects the second pump 40 to the dispensing nozzle 18. The second movable rod 42 is a movable hollow rod portion that controls the actuation of the second pump 40. The second movable rod includes a second product outlet 78 located at the top end of the rod 42 and a second annular groove 80. The outlet 78 is inserted into the nozzle 18. The second annular groove 80 extends around the second product outlet 78 at the top end of the rod 42. As will be described below, the nozzle 18 extends within the second annular groove 80 such that the nozzle 18 is connected to the rod 42. The displacement of the rod 42, substantially parallel to the axis B-B' of the second pump, allows the second cosmetic product to be dispensed from the second sampling tube 44 to the second product outlet 78 via the second pump 40.

[0060] The second sampling tube 44 is installed upstream of the second pump 40 and protrudes downward from the first pump 40. The second sampling tube is immersed in the second receiving portion 26 to sample the second cosmetic product in the second receiving portion 26.

[0061] Dispensing nozzle 18 is connected to first dispenser 14 and second dispenser 16. Specifically, dispensing nozzle 18 is connected to first movable rod 32 and second movable rod 42. The dispensing nozzle can be in a static upper position relative to container 12 (e.g., Figure 1(as shown) and the lower parting position (as shown) Figure 2 The dispensing nozzle 18 is configured to be moved by the user from a stationary position to a dispensing position to dispense the first and second cosmetic products from the container 12.

[0062] The dispensing nozzle 18 includes at least: conduits 48 and 50 for dispensing a first cosmetic product and a second cosmetic product, a top pressing surface 52, and a guide wall 54. For example, as shown in the figures, the dispensing nozzle includes a first dispensing conduit 48 and a second dispensing conduit 50. The dispensing nozzle 18 also includes at least one dispensing opening (not visible in the figures) that is fluidly connected to at least one conduit 48 or 50 and adapted to dispense the cosmetic product to the outside of the nozzle 18.

[0063] At least one conduit 48, 50 is fluidly connected to a first product outlet of a first movable rod 32 and a second product outlet of a second movable rod 42. A first dispensing conduit 48 is connected to the first movable rod 32, and a second dispensing conduit 50 is connected to the second movable rod 42. The first dispensing conduit 48 includes a tubular wall defining a flow path through which a first cosmetic product is designed to flow. The second dispensing conduit 50 includes a tubular wall defining a flow path through which a second cosmetic product is designed to flow. The first dispensing conduit 48 and the second dispensing conduit 50 are connected to a single dispensing opening. In a variant, the first dispensing conduit 48 and the second dispensing conduit 50 are each connected to a corresponding dispensing opening.

[0064] The pressing surface 52 is designed to be pressed by the user to displace the dispensing nozzle 18 from a rest position to a dispensing position. When the pressing surface 52 is pressed, the dispensing nozzle 18 is displaced along the device axis X-X' toward the container 12. For example, the device 10 also includes a spring mechanism (not shown) configured to return the dispensing nozzle 18 from the dispensing position to the rest position when the user is not pressing on the pressing surface 52.

[0065] As will be described in more detail below, the guide wall 54 is guided by the guide support 20 between the rest position and the dispensing position. Specifically, the guide wall 54 of the nozzle 18 is guided within the intermediate guide space 62 by the inner guide portion 58 and the outer guide portion 60 of the guide support 20, such that the nozzle 18 translates only between the rest position and the dispensing position parallel to the first pump axis A-A' and the second pump axis B-B'. For example, the guide wall 54 of the nozzle slides between the rest position and the dispensing position on the inner guide portion 58 and the outer guide portion 60 of the guide support 20.

[0066] A guide support 20 is mounted on the container 12 between the container 12 and the nozzle 18. The guide support 20 includes an inner guide portion 58 and an outer guide portion 60. The inner guide portion 58 and the outer guide portion 60 define an intermediate guide space 62 between them.

[0067] The guide support 20 also includes a connecting portion 64 that connects the inner guide portion 58 and the outer guide portion 60. In this case, the intermediate guide space 62 is defined between the inner guide portion 58, the outer guide portion 60, and the connecting portion 64.

[0068] For example, the inner guide portion 58 includes two collars 84, each movable rod 32, 42 being guided between a rest position and a distributing position by one collar 84. Advantageously, the inner guide portion 58 also includes at least one inner sleeve 86. As shown in the figures, the inner guide portion includes two inner sleeves 86. The inner guide portion 58 also includes an inner intermediate connecting region between the inner sleeves 86. Here, the inner guide portion 58 also includes radially outwardly projecting radial fins 90 from the inner sleeve or each inner sleeve 86. For example, as... Figure 3 As shown, for each inner sleeve 86, the inner guide portion 58 includes three radial fins 90 protruding from the inner sleeve 86.

[0069] The outer guide portion 60 includes at least one outer sleeve 96. As shown in the figures, the outer guide portion 60 advantageously includes two outer sleeves 96. In this case, the outer guide portion 60 also includes an outer intermediate connecting region 98 between the outer sleeves 96. Figure 3 (See in the image). The outer guide portion 60 includes an inner surface facing the first pump axis A-A' and / or the second pump axis B-B' and an outer surface opposite the inner surface.

[0070] The joining portion 64 includes at least one annular joining portion 102. As shown in the figures, the joining portion 64 includes two annular joining portions 102.

[0071] The intermediate guide space 62 is complementary to the guide wall 54 of the nozzle 18, such that the nozzle 18 is displaced between a rest position and a dispensing position according to a single degree of freedom, corresponding to a translational component parallel to the first pump axis A-A' and the second pump axis B-B'. "Complementary" means that the shape of the intermediate guide space 62 is complementary to the shape of the guide wall 54. The outer intermediate connecting region 98 defines at least a portion of the intermediate guide space 62 outward and protrudes toward a plane including the first pump axis AA and the second pump axis B-B'. The guide wall 54 is guided within the intermediate guide space 62 by the outer intermediate connecting region 98 between the rest position and the dispensing position. For example, the intermediate guide space is defined between the radial fin 90 and the sleeve or each sleeve 96. In a variant not shown, the inner intermediate connecting region has a recess extending toward a plane including the first pump axis A-A' and the second pump axis B-B', and the inner intermediate connecting region inward defines at least a portion of the intermediate guide space 62. Therefore, the guide wall 54 is guided by the inner intermediate connecting region in the intermediate guide space 62 between the static position and the distribution position.

[0072] The annular grooves 70 and 80 of each rod 32 and 42 are centered with respect to the corresponding pump axes A-A' and B-B'. The tubular walls of each distribution conduit 48 and 50 extend within the corresponding annular grooves 70 and 80.

[0073] As shown in the attached figures, each inner sleeve 86 has a cross-section that, when projected onto a projection plane perpendicular to the first pump axis A-A' and the second pump axis B-B', has a generally circular shape. Each inner sleeve 86 has a width. The width of each inner sleeve 86 corresponds to the diameter of the inner sleeve.

[0074] As shown in the attached figure, each outer sleeve 96 has a cross-section that, when projected onto the projection plane, has a generally circular arc shape.

[0075] The inner intermediate connecting area is the joint between the two inner sleeves 86. For example, as shown... Figure 1 and Figure 2 As shown, the inner intermediate connecting region extends in the extending plane of the annular joint 102. The two inner sleeves 86 and the intermediate connecting region define a space between them. The minimum width of the inner intermediate connecting region when projected onto the projection plane is less than the maximum width of each inner sleeve 86. The minimum width of the inner intermediate connecting region corresponds to the minimum distance between the two inner sleeves 86.

[0076] Each radial fin 90 extends in a plane including either the first pump axis A-A' or the second pump axis B-B'. As shown in the figures, each radial fin 90 protrudes from the portion of the corresponding inner sleeve 86 opposite the inner intermediate connection area toward the outer sleeve 96. Each radial fin 90 extends from the corresponding inner sleeve 86 to a guide edge 106. The guide edge 106 extends parallel to the corresponding pump axes A-A' and B-B'. The guide wall 54 is guided between a rest position and a dispensing position by contacting the outer sleeve 96 and the guide edge 106.

[0077] The outer intermediate connecting region 98 corresponds to the transition region between the two outer sleeves 96. The outer intermediate connecting region 98 constitutes a narrowing region between the two outer sleeves 96. The outer intermediate connecting region is a curved region including a peak oriented towards the inner intermediate connecting region. Figure 3 As shown, the intermediate guide space 62 therefore has a cross-section that, when projected onto the projection plane, is approximately figure-eight shaped. This arrangement further ensures that the displacement of the nozzle 18 is restricted to a single degree of freedom. Specifically, as Figure 3 As shown, the outer intermediate connecting region 98 is defined by the inner surface of the outer guide portion 60. The outer surface of the outer guide portion 60 has an approximately elliptical shape, but it does not necessarily match the shape of the inner surface.

[0078] The use of device 10 for dispensing cosmetic products will now be described.

[0079] When dispensing a specific amount of the first and second cosmetic products, the user moves the nozzle 18 from a rest position to a dispensing position. Advantageously, the user presses the nozzle 18 downwards onto the pressing surface 52 toward the container 12. During this movement, the guide wall 54 of the nozzle 18 is guided within the intermediate guide space 62 by the inner guide portion 58 and the outer guide portion 60, causing the nozzle 18 to move from the rest position to the dispensing position parallel to the first pump axis A-A' and the second pump axis B-B'.

[0080] During this movement, movable rods 32 and 42 move downwards and actuate pumps 30 and 40.

[0081] Then, the first cosmetic product is pumped from the first receiving portion 24 into the first sampling tube 34, through the first pump 30 to the first movable rod 32, and through the first dispensing conduit 48 to the dispensing opening.

[0082] Simultaneously, the second cosmetic product is pumped from the second receiving portion 26 into the second sampling tube 44, passes through the second pump 40 to the second movable rod 42, and passes through the second dispensing conduit 50 to the dispensing opening.

[0083] Therefore, the user can mix the two products outside the device 10 at the opening of the nozzle 18.

[0084] For example, when the user stops pressing on the pressing surface 52, the spring mechanism of the device 10 returns the dispensing nozzle 18 from the dispensing position to the resting position. The device 10 is then ready to dispense cosmetic products again.

[0085] According to a variant not shown, the outer surface of the outer guide portion 60 matches the shape of the inner surface of the outer guide portion 60. Therefore, the outer surface of the outer guide portion 60 also has a cross-section that, when projected onto a projection plane, has an approximately figure-eight shape.

[0086] According to this variant, the device 10 further includes a blocking element for blocking the dispensing nozzle 18. The blocking element includes a mating surface that matches the shape of the outer surface of the outer guide portion 60 and an adjacent surface that is substantially perpendicular to the axes A-A', B-B', with the mating surface specifically facing the narrowed region between the two outer sleeves 96. The blocking element is movable between a blocking position and a deblocking position. In the blocking position, the blocking element blocks the dispensing nozzle 18 in an upper rest position, and in the deblocking position, the blocking element allows the dispensing nozzle 18 to move from the upper rest position to a lower dispensing position.

[0087] In the blocking position, the mating surface of the blocking element is flush with the outer surface of the outer guide portion, particularly facing the narrowed area between the two outer sleeves 96. In the blocking position, the dispensing nozzle 18 rests against the adjacent surface of the blocking element and cannot move toward the lower dispensing position.

[0088] In the unblocked position, the blocking element is away from the outer guide portion. Therefore, the dispensing nozzle 18 can be moved from the upper rest position to the lower dispensing position.

[0089] Therefore, if the user wishes to block the dispensing nozzle 18, he / she sets the blocking element in its blocking position. Before using the device 10, the user sets the blocking element in its unblocking position.

[0090] Due to the fit between the dispensing nozzle 18 and the guide support 20, the nozzle 18 is precisely guided parallel to the two pump axes A-A' and B-B', causing the two pumps 30 and 40 to be actuated simultaneously and identically. This enables the delivery of approximately equal amounts of the first and second cosmetic products.

[0091] Therefore, device 10 is highly accurate in its product delivery while remaining easy to use and easy to manufacture.
