Description

Packaging and dispensing device for double content
The present invention relates to a packaging and dispensing device for fluid products, preferably cosmetic products. More specifically, the present invention relates to a packaging and dispensing device for fluid cosmetic compositions, comprising : a container extending along a main axis and comprising a first compartment, for storing a first fluid composition, and a second compartment for storing a second fluid composition isolated from the first fluid composition ; a dispensing head comprising at least one dispensing orifice, each of the first and second compartments being in fluid communication with said dispensing head ; a rotation ring configured to rotate around the main axis relative to the container ; and a first piston forming an inner wall of the first compartment and a second piston forming an inner wall of the second compartment ; each of the first and second pistons being configured to lessen an inner volume, respectively of the first and of the second compartment, by axial translation relative to an inner surface of, respectively, said first or said second compartment.
The term “cosmetic product” is understood to mean a product as defined in Council Directive 1223/2009/EEC of 30 November 2009.
Due to chemical reactions occurring in cosmetic compositions, it may be useful to provide a cosmetic product in the form of at least two distinct fluid compositions which are mixed within a short time before use. Therefore, it is possible to manufacture and store the compositions separately, without degradation of the active components.
In such cases, it is advantageous to provide a packaging and dispensing device allowing an easy mixing of the at least two distinct fluid compositions before application.
A packaging and dispensing device as described above is known from document CN112367878 in the name of the Applicant. This document describes a cosmetic container receiving a rotatable rod, said rod comprising two threaded parts with opposite directions. A different piston cooperates with each threaded part, so that the rotation of the rod allows to push two different fluid compositions out of the container.
Due to the chemical contents and reactions involved in the cosmetic composition, it may be preferable or even necessary to precisely control the relative amounts of different fluid compositions delivered out of the container. However, due to its design, such a control is difficult in the device disclosed in CN112367878.
An object of the present invention is to provide a packaging and dispensing device for dual content, with a simplified manufacturing process. In particular, an object of the present invention is to allow a precise defining of the relative amounts of different fluid compositions delivered out of the container.
To this end, the invention relates to a packaging and dispensing device for double content as described above, wherein : the packaging and dispensing device also comprises a first tubular element extending along the main axis, a first axial end of said first tubular element being fixed to the first piston, said first tubular element comprising a threaded outer surface able to cooperate with a threaded inner surface of the rotation ring, so that a rotation of said rotation ring leads to the axial translation of the first piston relative to the inner surface of the first compartment ; the second compartment is situated inside the first tubular element ; and the packaging and dispensing device also comprises a second tubular element, an open first axial end of said second tubular element being fixed to the second piston and extending across a central hole of the first piston, a second axial end of said second tubular element being fixed to the inner surface of the first compartment ; so that the axial translation of the first piston relative to the inner surface of the first compartment induces a same axial translation of the inner surface of the second compartment relative to the second piston.
Such a configuration allows to precisely control the relative amounts of first and second fluid compositions delivered out of the container.
According to advantageous embodiments, the packaging and dispensing device comprises one or more of the following feature (s) , taken in isolation or according to any technically possible combination :

- the packaging and dispensing device further comprises a cap configured for being reversibly assembled to the dispensing head so as to seal the at least one dispensing orifice, the cap preferably comprising a layer of elastomer intended to come into contact with said at least one dispensing orifice ;
- the dispensing head comprises at least a first and a second dispensing orifices ; and the first and second compartments are in fluid communication, respectively, with the first and with the second dispensing orifices ;

In the embodiment of figures 1 and 2, the packaging and dispensing device 10 also comprises a cap 16.
The container 12 extends along a main axis 20, which is considered vertical in the following description, relative to the terms “top/bottom” .
The container 12 comprises an outer body 22, forming a top part of an outer surface of the device 10. The outer body 22 has a substantially cylindrical shape.
Inside the outer body 22, the container 12 also comprises a first 24 and a second 26 compartments. The first 24 and second 26 compartments are configured for storing, respectively, a first and a second fluid compositions isolated from each other.
More specifically, the container 12 comprises an inner body 28, received in the outer body 22 in a fixed manner. The inner body 28, shown on figure 3, comprises a cylindrical wall 30, extending along the main axis 20, and a bottom wall 32. Said bottom wall is substantially perpendicular to the main axis 20 and comprises a central opening 34.
A cylindrical inner surface 35 of the cylindrical wall 30 is part of the first compartment 24.
The inner body 28 also comprises a ribbed ring 36, opposite the cylindrical wall 30 relative to the bottom wall 32. The ribbed ring 36 comprises inner ribs extending toward the main axis 20.
The container 12 also comprises a first tubular element 37, extending along the main axis 20 and received in the outer body 22. A cylindrical inner surface 38 of the first tubular element 37 is part of the second compartment 26.
As detailed below, the first tubular element 37 is mobile relative to the outer body 22.
The dispensing assembly 14 comprises : a dispensing head 40 ; a rotation body 42; a first 44 and a second 46 pistons ; and a second tubular element 48.
The dispensing head 40 forms a top end of the packaging and dispensing device 10 along the main axis 20. The dispensing head 40 comprises at least one dispensing  orifice  50, 52.
Each of the first 24 and second 26 compartments is in fluid communication with the dispensing head 40. Preferably, the dispensing head 40 comprises at least one first dispensing orifice 50, in fluid communication with the first compartment 24, and at least one second dispensing orifice 52, in fluid communication with the second compartment 26.
In the embodiment of figures 1 and 2, the dispensing head 40 comprises a group of first dispensing orifices 50 and a group of second dispensing orifices 52. The second dispensing orifices 52 are gathered close to the main axis 20 and the first dispensing orifices 50 are disposed along a circle around the second dispensing orifices 52.
In the embodiment of figures 1 and 2, a top wall of the first compartment 24 is formed by the dispensing head 40 and the first dispensing orifices 50 open on said first compartment.
In the embodiment of figures 1 and 2, the dispensing head 40 also comprises a cupped outer surface 54. The first 50 and second 52 dispensing orifices open on said cupped outer surface.
The rotation body 42, shown on figure 3, extends along the main axis 20 and comprises a rotation ring 56, a threaded inner surface 58 and a cogged crown 60.
The rotation ring 56 has a substantially cylindrical shape, with a substantially same diameter as the outer body 22. The rotation ring 56 is aligned with the outer body 22 along the main axis 20 and forms a bottom part of the outer surface of the device 10.
The threaded inner surface 58 of the rotation body 42 is received in the outer body 22, adjacent to the inner body 28 along the main axis 20. The threaded inner surface 58 is  disposed around the first tubular element 37 and is able to cooperate with outer threads 62 formed in an outer surface of said first tubular element 37.
The cogged crown 60 of the rotation body 42 is disposed around the threaded inner surface 58. As described below, the cogged crown 60 is configured for cooperating with the ribbed ring 36 of the inner body 28, so as to form an anti-rotation device. Said  anti-rotation device  36, 60 allows the rotation of the rotation ring 56 relative to the container 12 in one direction only. Preferably, a visual indictor 63 is provided on the rotation ring 56 for indicating the allowed rotation direction.
The first piston 44 is in contact with the cylindrical wall 30 of the inner body 28 and forms a bottom wall of the first compartment 24. The first piston 44 has a central hole 64 and is formed in one piece with a top end of the first tubular element 37.
As described below, the first piston 44 is able to axially slide against the inner surface 35 of the inner body 28, so as to lessen an inner volume of the first compartment 24. In the same manner, the first tubular element 37 is able to axially slide in the central opening 34 of the bottom wall of the inner body 28.
The second piston 46 is in contact with the inner surface 38 of the first tubular element 37 and forms a top wall of the second compartment 26.
The second tubular element 48 is formed in one piece with the second piston 46. A bottom end of the second tubular element 48 opens on said second piston 46 and on the second compartment 26. A top end of the second tubular element 48 is fixed to the dispensing head 40 and opens on the second dispensing orifices 52.
The inner surface 38 of the first tubular element 37 is able to axially slide against the second piston 46, so as to lessen an inner volume of the second compartment 26. In the same manner, the first piston 44 is able to axially slide along the second tubular element 48, said second tubular element being received in the central hole 64 of the first piston.
More specifically, the first tubular element 37 and the first piston 44 are blocked in rotation relative to the outer 22 and inner 28 bodies and to the dispensing head 40. For example, a friction joint 65 disposed around the second piston 46, in contact with the inner surface 38, blocks the rotation of the first tubular element 37 while allowing its axial translation.
Therefore, the cooperation of the threaded inner surface 58 of the rotation body 42 with the outer threads 62 of the first tubular element 37 induces an axial translation of said first tubular element and of the first piston 44.
Moreover, the rotation direction allowed by the  anti-rotation device  36, 60 corresponds to an axial translation of the first piston 44 in the direction of the dispensing head 40.
In the embodiment of figures 1 and 2, the dispensing assembly 14 also comprises a plug 66 inserted in a bottom end of the first tubular element 37 and forming a bottom wall of the second compartment 26.
The plug 66 comprises a pusher 68 extending in the second compartment 26. The pusher 68 has a substantially cylindrical shape, with a diameter smaller than an inner diameter of the second tubular element 48. As described below, the pusher 68 is able to axially move in the second tubular element 48.
The cap 16 comprises a domed inner surface 70, substantially complementary with the cupped outer surface 54 of the dispensing head 40.
The cap 16 is configured for being reversibly assembled to a top end of the outer body 22 and to the dispensing head 40, for example by means of threads 72. In an assembled configuration, shown on figure 2, the domed inner surface 70 is in contact with the cupped outer surface 54 and seals the dispensing  orifices  50, 52. In a dissociated configuration, shown on figure 1, the dispensing  orifices  50, 52 and the cupped outer surface 54 are accessible to a user.
Preferably, the domed inner surface 70 is formed by a layer of elastomer for a better sealing of the dispensing  orifices  50, 52 in the assembled configuration.
A method for the use of the packaging and dispensing device 10 will now be described. The manufacturing of the device 10 includes the filling of the first compartment 24 with a first fluid cosmetic composition, and the filling of the second compartment 26 with a second fluid cosmetic composition. The first and second fluid compositions are preferably chosen with cream or gel textures.
The first and second fluid compositions are intended to be mixed immediately before use, in specified proportions, so as to form a cosmetic product ready to be applied on the body of a user.
Preferably, the filling of the first 24 and second 26 compartments occurs with the dispensing assembly 14 in an initial configuration, shown on figure 2, wherein the first piston 44 is axially in contact with the bottom wall 32 of the inner body 28. More preferably, the first 24 and second 26 compartments are filled so that an inner volume of said compartments, in the initial configuration, is substantially completely occupied by the first or second fluid composition.
When a user wishes to use the device 10, he/she unscrews the cap 16 and rotates the rotation ring 56 according to the visual indictor 63. Therefore, the first piston 44 is translated in the direction of the dispensing head 40, thereby lessening the inner volume of the first compartment 24. The first fluid composition is pushed out of said first compartment by the first dispensing orifices 50.
Simultaneously, the first tubular element is translated in the same direction as the first piston. The plug 66 gets closer to the second piston 46, thereby lessening the inner volume of the second compartment 26.
The second fluid composition is pushed from the second compartment 26 to the second tubular element 48 and to the second dispensing orifices 52 of the dispensing head 40.
Therefore, a first amount of the first fluid composition and a second amount of the second fluid composition are united in the cupped outer surface 54 of the dispensing head 40. The user is then able to collect the resulting composition and to apply it on his/her body, after optionally completing the mixing of the composition between his/her fingers.
The axial translation of the first piston 44 relative to the inner body 28 is the same as the axial translation of the first tubular element 37/plug 66 relative to the second piston 46. Therefore, the volume lessening of the first 24 and of the second 26 compartments is coordinated.
As a consequence, the ratio between the diameters of the  inner surfaces  35, 38 of the first 24 and second 26 compartments, as well as the ratio between the diameters of the first 44 and second 46 pistons, determines the relative proportions of first and second fluid compositions simultaneously delivered by the first 50 and second 52 dispensing orifices.
Therefore, the contents of the composition formed in the cupped outer surface 54 is controlled by the design of the packaging and dispensing device 10. For example, in the embodiment of figures 1 and 2, the ratio between the delivered amounts of first and second fluid compositions is 3/1.
Due to the  anti-rotation device  36, 60, an unwished increasing of the inner volumes of the  compartments  24, 26 is prevented, for example between two uses of the device 10. Therefore, the relative proportions of the first and second fluid compositions are maintained as long as the device 10 is able to dispense product out of the first 50 and the second 52 dispensing orifices.
During the course of the first piston 44/first tubular element 37, the pusher 68 is introduced in the second tubular element 48. A space between said pusher and said second tubular element 48 allows the second fluid composition to be pushed around the pusher 68 toward the dispensing head 40. However, the volume occupied by the pusher 68 in the second tubular element 48 allows the release of a corresponding volume of second fluid composition, which would otherwise be trapped inside said second tubular element at the end of the course of the first tubular element. In other terms, the pusher 68 contributes to reduce residual bulk of second fluid composition.
Therefore, the packaging and dispensing device 10 described above allows the storage of two fluid compositions isolated from each other, and the further delivery of an amount of each composition so as to form a mixture with controlled proportions.
The design of the device, especially the diameter ratio between the compartments and between the pistons, determines the proportions of the two fluid compositions in the resulting mixtures. Such a design is easy to adapt to a specified cosmetic product.
Preferred features, such as the anti-rotation device and the pusher, provide a better security and a more economical design.
