Description

Hinged applicator for a cosmetic product
and associated packaging and application assembly
The present invention relates to a cosmetic product applicator, of the type comprising: an application member extending along a first longitudinal axis, a first end of said application member comprising an application element; and a gripping member extending along a second longitudinal axis and connected by a hinge to a second end of the application member.
The term "cosmetic product", refers, according to this invention, to a product as defined in Regulation (EC) N° 1223/2009 of the European Parliament and of the Council of November 30, 2009, on cosmetic products.
The cosmetic product for which the applicator according to the invention is intended is in particular in the form of a powder, a compacted solid, or preferentially a fluid such as a liquid. The product is advantageously a product intended to be placed on the keratin fibers of a user, such as the eyelashes or the eyebrows. The product is for example a makeup product such as a mascara.
In order to benefit from improved ergonomics for applying makeup, it is known to provide applicators of the type cited above, wherein the application element can be oriented in a variable manner with respect to the gripping member. Such a hinged applicator is particularly described in the document EP1369056, held by the Applicant.
The industrial manufacture of such hinged applicators typically comprises one or a plurality of assembly and/or conveying steps, during which the gripping member can be inclined with respect to the application element. Applicators of different inclinations can as such be found mixed together on a conveying line before screwing onto an associated container. The position of the applicators on the conveyor is thus uncertain, which complicates the gripping thereof by an automaton or an operator with a view to screwing, as well as any packaging thereof after screwing. Furthermore, applicators in the inclined position take up more space on the conveyor than "straight" applicators wherein the application member is substantially aligned with the gripping member.
In order to solve this problem, it is known to use conveying platforms comprising housings which hold the applicators in the "straight" position until screwing or packaging.
The aim of the present invention is that of facilitating the industrial manufacture of such hinged applicators, particularly by doing away with the use of such conveying platforms.
For this purpose, the invention relates to an applicator of the type cited above, wherein the gripping member comprises: a supporting member forming the hinge with the second end of the application member; and a locking element, rotatable with respect to the supporting member about the second longitudinal axis, between a release position and a locking position. Advantageously, the removable locking element forms a first stop between the gripping member and the application member, so as to lock the hinge and keep the first and second longitudinal axes substantially aligned.
The locking element thereby makes it possible to keep the application member and the gripping member aligned, during the manufacture of the applicator and the assembly thereof with a container.
According to further advantageous aspects of the invention, the applicator comprises one or several of the following features taken in isolation or in any technically possible combination:
- the hinge between the gripping member and the application member is a pivot connection along a third axis of rotation substantially perpendicular to the first and second longitudinal axes, the gripping member and the application member being configured such that, in the release position of the locking element, the gripping member is movable with respect to the application member about said third axis of rotation, between a first and a second positions of the second longitudinal axis with respect to the first longitudinal axis, said first and second positions being determined respectively by a second and by a third stops formed by the gripping member against the application member;
- the first position of the second longitudinal axis with respect to the first longitudinal axis corresponds to the substantially parallel first and second longitudinal axes; such a configuration particularly makes it possible to provide "straight" applicators, particularly during storage or conveying;
- an angular clearance of the gripping member with respect to the application member, between the first and second positions, is between 30° and 60°;
- the locking element comprises a tubular cover arranged around the supporting member, one axial end of said cover being formed by a first and by a second adjacent edges, the first edge being substantially perpendicular to the second longitudinal axis, the second edge being inclined with respect to said first edge, such that, in the locking position of the locking element, said first edge is suitable for forming the first stop against the application member;
- in the release position of the locking member, the first and second edges are respectively suitable for forming the second and third stops against the application member;
- the tubular cover and the supporting member comprise a device for locking the locking element in the release position; if applicable, the applicator can thereby be held in the "straight" position; - the locking device comprises a first and a second locking elements, respectively borne by an internal surface of the tubular cover and by an external surface of the supporting member; said first and second locking elements are suitable for snap- fastening, or in other words snap-locking, with one another by rotating the tubular cover with respect to the supporting member about the second longitudinal axis, between the locking position and the release position of the locking element.
The invention further relates to an assembly for packaging and applying a cosmetic product comprising: a cosmetic product applicator as described above, and a container intended to contain said cosmetic product, the applicator and the container comprising a reversible assembly device in a storage configuration, wherein the application element of the applicator is received in an internal volume of the container.
According to an advantageous aspect of the invention, the reversible assembly device comprises a first and a second screwing elements, respectively borne by the applicator and by the container, enabling screwing/unscrewing of the applicator on the container by rotating about the first longitudinal axis of the application member.
The invention further relates to a method for manufacturing a cosmetic product packaging and application assembly as described above, comprising the following steps: the supporting member and the locking element are assembled in the locking position to form the gripping member; then the hinge is formed between said gripping member and the application member to form the applicator; then the first and second screwing elements are screwed to assemble the applicator with the container; then the tubular cover of the locking element is rotated with respect to the supporting member about the second longitudinal axis, so as to snap-fasten, or in other words snap-lock, the first and second elements in the release position of the locking element.
According to further advantageous aspects of the invention, the manufacturing method comprises one of the following features:
- the tubular cover is rotated with respect to the supporting member in the direction of screwing of the first screwing element of the applicator onto the second screwing element of the container; or
- the tubular cover is rotated with respect to the supporting member in the opposite direction of screwing of the first screwing element of the applicator onto the second screwing element of the container.
These two alternative embodiments make it possible to release the applicator during two different steps of the method, as described hereinafter.
The invention will be easier to understand in view of the following description, provided solely as a non-restrictive example and with reference to the drawings, wherein: - figure 1 is a longitudinal cross-section view of a packaging and application assembly according to a first embodiment of the invention, comprising an applicator and a container;
- figure 2 is an exploded perspective view of the applicator in figure 1 ;
- figure 3 is a detailed, partial cross-section view of a packaging and application assembly according to a second embodiment of the invention, in a first configuration; and
- figure 4 is a detailed, partial cross-section view of the packaging and application assembly in figure 3, in a second configuration.
Figures 1 and 2 show a cosmetic product packaging and application assembly 10 according to a first embodiment of the invention. Figures 3 and 4 show a cosmetic product packaging and application assembly 1 10 according to a second embodiment of the invention.
Apart from differences detailed hereinafter, the assemblies 10 and 1 10 are equivalent and will be described simultaneously. The elements common to the assemblies 10 and 1 10 are designated by the same reference numbers.
The assembly 10, 1 10 is particularly intended for packaging and applying mascara. The assembly 10, 1 10 particularly comprises a container 12 and an applicator 14, 1 14.
The container 12 particularly comprises a side wall 16 and a bottom 18, which define an internal volume 20 suitable for receiving a cosmetic product, in particular a liquid mascara type composition.
The container 12 further comprises a neck 22, of tubular shape, wherein an external wall comprises a thread 24.
The container 12 also comprises a squeezing member 26, also of tubular shape, inserted into the neck 22 and extending into the internal volume 20.
The applicator 14, 1 14 comprises an application member 30 and a gripping member 32, 132, hinged with respect to one another. More specifically, the application 30, 130 and gripping 32, 132 members extend respectively along a first longitudinal axis 34 and along a second longitudinal axis 36; and said application 30 and gripping 32, 132 members are connected by a pivot connection along a third axis of rotation 38, perpendicular to the first 34 and second 36 longitudinal axes.
According to an alternative embodiment not shown, the application and gripping members are connected by another type of hinge, for example a swivel connection.
Figures 1 , 3 and 4 show the applicator 14, 1 14 in a first angular configuration, wherein the first 34 and second 36 longitudinal axes are merged. The application member 30 comprises: a rod 40 extending along the first longitudinal axis 34; an application head 42, arranged at a first end of the rod; a cap 44 for closing the container 12; and a hinge element 46 with the gripping member 32, 132. The closing cap 44 and the hinge element 46 are arranged at a second end of the rod 40.
The application head 42 is typically a mascara brush or comb. More particularly, the application head 42 comprises an elongated core, as well as a plurality of reliefs such as bristles or pins, projecting laterally from said core.
The closing cap 44 is preferably formed from one piece, or in other words integral, with the second end of the rod 40. Said closing cap has substantially the shape of a ring arranged along the first longitudinal axis 34. An internal surface of said ring comprises an internal thread 48. Said internal thread is suitable for engaging with the thread 24 of the neck 22 to assemble the container 12 and the applicator 14, 1 14 in a storage configuration, represented in figures 1 , 3 and 4. In said storage configuration, the applicator 14, 1 14 closes the container 12 and the application head 42 is received in the internal volume 20.
According to alternative embodiments not shown, further known devices for assembling the closing cap 44 and the neck 22 are used, such as a snap-locking or other assembly device.
An axial end of the closing cap 44, opposite the application head 42, consists of a ring-shaped surface 50. Said ring 50 is, in the embodiment illustrated, planar, perpendicular to the first longitudinal axis 34 and oriented in the opposite direction to the application head 42. Alternatively, this ring can be non-planar and/or non-perpendicular to the first axis.
The hinge element 46 extends the closing cap 44 axially from the ring 50, said hinge element 46 and closing cap 44 being formed preferably from one piece, or in other words integral.
In the embodiment illustrated, the hinge element 46 comprises a rounded body 52, having substantially the shape of a sphere portion. The hinge element 46 further comprises two circular cavities 54, suitable for forming a hinge to represent the third axis of rotation 38, as described hereinafter.
The gripping member 32, 132 comprises an internal sleeve 60, 160 and an external cover 62.
The sleeve 60, 160 comprises a side wall 63, 163, of substantially tubular shape and extending along the second longitudinal axis 36.
An external surface of the side wall 63, 163 of the sleeve 60, 160 comprises a ring
66 forming a radial projection. The ring 66 defines two portions of the side wall 63, 163, adjacent along the second longitudinal axis 36 and referred to as proximal portion 70 and distal portion 72, 172.
An internal surface of the proximal portion 70 comprises two lugs 74, in radial projection. The lugs 74 are substantially aligned along a diameter of a cross-section of the sleeve 60, 160. The lugs 74 are inserted into the circular cavities 54 of the hinge element 46 of the application member 30. The lugs 74 and the circular cavities 54 thereby form a hinge, representing the third axis of rotation 38 of the sleeve 60, 160 with respect to the application member 30.
A free end of the proximal portion 70 is formed by a first 76 and a second 78 edges, substantially arranged on either side of a plane containing the second longitudinal 36 and the third axis of rotation 38. Each of the first 76 and second 78 edges forms a substantially planar surface. The first edge 76 is substantially perpendicular to the second longitudinal axis 36.
The second edge 78 is formed by a beveled cut in the proximal portion 70. More specifically, the second edge 78 is substantially parallel with the third axis of rotation 38 and inclined by an angle a with respect to the first edge 76. The first angle a is between 5° and 90°, preferentially between 30° and 60°, more preferentially equal to approximately 45°.
The distal portion 72, 172 of the side wall 63, 163 of the sleeve 60, 160 comprises at least one surface 80, 180 for guiding and locking the cover 62. The guiding surface 80, 180 extends over an angular portion 79 of an external surface of the side wall 63, 163. A second angle β formed by the angular portion 79 is between 5° and 180°, preferentially between 20° and 165°, for example close to 90°, and more preferentially between 30° and 60°.
The guiding surface 80, 180 is defined angularly by a first 81 and a second 82 lateral stops. The term "lateral stops" denotes surfaces included in planes containing the second longitudinal axis 36. Said lateral stops are formed by an external radius of the distal portion 72, 172, smaller inside the angular portion 79 than on either side of said angular portion.
Said external radius is substantially constant along the guiding surface 80, 180, with the exception of a ramp 83 arranged in the vicinity of the second lateral stop 82. The ramp 83 comprises a curved surface 84, oriented toward the first lateral stop 81 , as well as a planar surface 86, facing the second lateral stop 82 and forming a third lateral stop. A space included between the second 82 and third 86 lateral stops forms a locking notch 88, arranged parallel with the second longitudinal axis 36. In the embodiments shown in figures 1 to 4, each sleeve 60, 160 comprises two guiding surfaces 80, 180, identical and symmetrical to one another with respect to the second longitudinal axis 36.
The sleeve 60 of the applicator 14 in figures 1 and 2 is identical to the sleeve 160 of the applicator 1 14 in figures 3 and 4, except for the distal portions 72 and 172 of the side walls 63 and 163. In particular, the distal portions 72 and 172, and particularly the guiding surfaces 80 et 180, are reflections of one another with respect to a plane passing through the second longitudinal axis 36. More specifically, a movement of the first lateral stop 81 toward the second lateral stop 82 corresponds to rotations in opposite directions for the sleeves 60 and 160.
The cover 62 comprises a side wall 90, of substantially tubular shape and extending along the second longitudinal axis 36. The sleeve 60, 160 is received inside said side wall 90.
An internal surface of the side wall 90 comprises a radial groove 91 . The ring 66 of the sleeve 60, 160 is snap-fastened, or in other words snap-locked, into the groove 91 which allows and guides a rotation of the cover 62 with respect to the sleeve 60, 160 about the second longitudinal axis 36.
An internal surface of the side wall 90 further comprises at least one longitudinal rib 92, substantially parallel with the second longitudinal axis 36 and forming an internal projection. The radial dimensions of the sleeve 60, 160 and of the cover 62 are chosen such that the rib 92 comes into contact with the guiding surface 80, 180. In particular, the rib 92 is suitable for snap-fastening, or in other words snap-locking, into the locking notch
88.
In the case of the assembly 10 in figures 1 and 2, a screwing direction of the internal thread 48 of the closing cap 44, on the thread 24 of the neck 22 corresponds to a direction of movement of the rib 92, from the first lateral stop 81 to the ramp 83 of the guiding surface 80.
On the other hand, in the case of the assembly 1 10 in figures 3 and 4, the screwing direction of the internal thread 48 on the thread 24 corresponds to a direction of movement of the rib 92 from the ramp 83 to the first lateral stop 81 of the guiding surface 180.
In the embodiments shown in figures 1 to 4, the cover 62 comprises two ribs 92, symmetrical to one another with respect to the second longitudinal axis 36, each of said ribs corresponding to a guiding surface 80, 180 of the sleeve 60, 160.
A distal end 93 of the side wall 90 is preferentially closed. A proximal end of the side wall 90 is open and defined by a third 94 and a fourth 96 edges. Each of the third 94 and fourth 96 edges forms a substantially planar surface. The third edge 94 is substantially perpendicular to the second longitudinal axis 36. The fourth edge 96 is formed by a beveled cut in the side wall 90 and is inclined by the first angle a with respect to the third edge 94.
The third 94 and fourth 96 are adjacent to one another at two ridges 97, substantially aligned along a transversal diameter of the side wall 90.
Figures 1 and 3 represent a first position, or release position, of the gripping member 32, 132. Said release position corresponds to a particular angular orientation of the cover 62 with respect to the sleeve 60, 160. Indeed, in said release position, the third 94 and fourth 96 edges of the cover 62 form continuous surfaces, respectively with the first 76 and second 78 edges of the sleeve 60, 160. Furthermore, in said release position, each of the two ribs 92 is snap-fastened, or in other words snap-locked, in the corresponding locking notch 88.
In the release position, the gripping member 32, 132 is suitable for pivoting about the third axis of rotation 38 with respect to the application member 30.
Figure 4 shows a second position, or locking position, of the gripping member 132. In said locking position, the two ridges 97 are situated on either side of the third axis of rotation 38, at a distance from said axis of rotation. The third 94 and the fourth 96 edges of the cover 62 are situated in different planes, respectively of the first 76 and of the second 78 edges of the sleeve 60, 160 and the third edge 94 of the cover 62 abuts axially against the ring 50. Furthermore, in said locking position, each of the two ribs 92 is situated between the first lateral stop 81 and the ramp 83 of the corresponding guiding surface 80, 180.
In the locking position, the third edge 94 of the cover 62 forms an axial stop against the ring 50 of the application member 30. The two ridges 97 being situated on either side of the third axis of rotation 38, said axial stop prevents the rotation of the gripping member 32, 132 with respect to the application member 30 about said third axis of rotation 38, in both directions of rotation. Said axial stop thus holds the applicator 14, 1 14 in the first angular configuration in figures 1 , 3 and 4, the first 34 and second 36 longitudinal axes being merged.
A method for manufacturing the assemblies 10 and 1 10 will now be described. Firstly, the container 12, the application member 30 and the gripping member 32, 132 are manufactured independently from one another. In particular, the rod 40, the closing cap 44 and the hinge element 46 are preferably formed from one piece, or in other words integral, by molding a plastic material. The application head 42 is then assembled with the rod 40 to form the application member 30. The sleeve 60, 160 and the cap 62 are manufactured independently from one another, preferably by molding. Then the sleeve 60, 160 is inserted into the cover 62. This insertion comprises a translation along the second longitudinal axis 36; during said translation, the sleeve 60, 160 and the cover 62 are oriented angularly such that each rib 92 of the cover is situated between the first lateral stop 81 and the ramp 83 of the corresponding guiding surface 80, 180.
The translation is continued until the snap-fastening, or in other words until the snap-locking, of the ring 66 of the sleeve 60, 160 in the groove 91 of the cover 62. The sleeve 60, 160 and the cover 62 are then fastened axially with respect to one another. The gripping member 32, 132 is thus formed.
At this stage, the cover 62 is in the position in figure 4, or locking position, with respect to the sleeve 60, 160. More specifically, the third 94 and the fourth 96 edges of the cover 62 are offset with respect, respectively, to the first 76 and second 78 edges of the sleeve 60, 160.
The gripping member 32, 132 is then assembled with the application member 30.
More specifically, the proximal portion 70 of the sleeve 60, 160 is assembled with the hinge element 46, so as to snap-fasten, or in other words to snap-lock, each of the two lugs 74 in a circular cavity 54. The applicator 14, 1 14 is thus formed.
At this stage, the first longitudinal axis 34 of the application member 30 and the second longitudinal axis 36 of the gripping member 32, 132 are merged. Furthermore, the third edge 94 of the cover 62 abuts axially against the ring 50. Said stop prevents the rotation of the gripping member 32, 132 with respect to the application member 30 about the third axis of rotation 38 in both directions of rotation, as described above.
During the conveying or handling of the applicator 14, 1 14 by automatons, on an assembly line, it is advantageous for the first 34 and second 36 longitudinal axes to be kept merged. The applicator 14, 1 14 is thereby less bulky and is easier for the automaton to pick up and handle.
The closing cap 44 of the applicator 14, 1 14 is then screwed onto the neck 22 of a container 12 filled with cosmetic product, so as to form the assembly 10, 1 10. During said screwing step, the applicator 14, 1 14 is particularly gripped by the cover 62.
The step for screwing the closing cap 44 onto the neck 22 will not be detailed for the assembly 10 in figures 1 and 2:
At the start of screwing, the torque applied to the applicator 14 is relatively low. Each rib 92 is kept in contact with the curved surface 84 of the ramp 83 of the corresponding guiding surface 80. When the closing cap 44 is fully screwed on the neck 22, the torque increases and the rib 92 moves along the curved surface 84, until it is snap-fastened, or in other words snap-locked, into the locking notch 88. The cover 62 is thereby locked with respect to the sleeve 60, in the release position of the gripping member 32 shown in figure 1 .
Then, the assembly 10 is optionally packaged, and marketed, with the gripping member 32 in the release position.
The step for screwing the closing cap 44 onto the neck 22, as well as the remainder of the manufacturing method, will now be detailed for the assembly 1 10 in figures 3 and 4. For the purpose of clarity in these figures 3 and 4, the cover 62 has been illustrated transparently and illustrated with mixed lines.
During screwing, each rib 92 is kept in contact with the first lateral stop 81 of the corresponding guiding surface 180. The screwing step thus holds the applicator 14, 1 14 in the position for locking the gripping member 132, shown in figure 4.
Then, the assembly 1 10 is optionally packaged, and marketed, with the gripping member 132 in the locking position.
During the first use of the assembly 1 10, a user takes hold of the cover 62 with one hand and of the closing cap 44 with the other. The user then turns said cover in the unscrewing direction of the applicator 14, 1 14 with respect to the container 12. Each rib 92 moves toward the ramp 83 of the corresponding guiding surface 180, then along the curved surface 84, until it is snap-fastened, or in other words snap-locked, into the locking notch 88. The cover 62 is thereby locked with respect to the sleeve 160, in the release position of the gripping member 132 shown in figure 3.
Continuing to hold the cover 62, the user picks up the container 12 with the other hand to continue the unscrewing movement, so as to separate the closing cap 44 from the neck 22.
A method for using the assembly 10, 1 10 will now be described. When the mascara is being applied, the application member 30 and the gripping member 32, 132 in the release position can be inclined with respect to one another, by means of the hinge formed by the lugs 74 and the circular cavities 54.
Said inclination can vary between a first and second angular configurations of the gripping member 32, 132 with respect to the application member 30. The first angular configuration, shown in figures 1 and 3, corresponds to the first 76 and third 94 edges, respectively of the sleeve 60, 160 and of the cover 62, abutting against the ring 50 of one side of the third axis of rotation 38. The second angular configuration, not shown, corresponds to the second 78 and fourth 96 edges, respectively of the sleeve 60, 160 and of the cover 62, abutting against the ring 50 of the other side of the third axis of rotation 38. The respective positions of the second longitudinal axis 36 in the first and second angular configurations are separated by the first angle a.
The first and second angular configurations described above thus define the set of possible angular configurations of the gripping member 32, 132 with respect to the application member 30. The user chooses and modifies the inclination of the first 34 and second 36 longitudinal axes according to the makeup operations performed using the assembly 10, 1 10.
