Description

The invention relates to a packaging device for a cosmetic product, in particular for a cosmetic product in solid or pasty form, that is to say which does not spread in the open air, such as lipstick or balm. lip, blush or eye shadow and foundation.

The documents US2007 / 0292344 A1 and FR 3 016 116 A1 disclose examples of packaging devices for cosmetic products.

From the state of the art, packaging devices for lipstick in particular are known, the device of which is opened by the tilting of a first part about an axis of rotation, this first part being completely interlocking. inside a second part to reveal the product in the open position of the device.

However, this type of device is often not suitable for limiting the travel of the cover during the tilting of the latter inside the base and for locking the cover in the open or closed position.

One of the objectives of the invention therefore consists in providing a solution for controlling the tilting movement of the cover when the packaging device is opened and for locking the cover both in the open position and in the closed position. .

One advantage of this invention is that it allows the consumer to use the device according to the invention without having to stop the stroke and block the cover. In other words, when the device is in the open position, the cover remains hidden in the base of the device, in a stable manner, without the cover returning to its course. The consumer can thus have access to the cosmetic product, without the inconvenience of a possible untimely return of the cover. In addition, random opening, for example in a handbag, is avoided.

Thus, the invention relates to a packaging device for a cosmetic product, in particular for a solid or pasty cosmetic product, comprising a base, an intermediate part intended to carry the cosmetic product, a cover and locking means, the intermediate part being mounted integrally. of the base and the cover being mounted articulated on the intermediate piece so that said cover occupies two positions, a first position, called the device closure, in which the base and the cover define a space substantially closed between them, said cosmetic product being housed inside the cover, and a second position, called the opening of the device, in which the cover is retracted inside the base, in which said cover is configured to be locked in the open position - conversely in the closed position - by locking means comprising at least one protuberance of material projecting from the intermediate piece.

In the remainder of the description, elements and components having an identical, analogous or similar structure or functions will be designated by the same references.

In the remainder of the description, longitudinal, vertical and transverse orientations will be adopted by convention and without limitation, with reference to the trihedron (L, V, T) shown in all of the figures. The vertical direction is used as a geometric reference unrelated to the direction of Earth's gravity. The axis (R) of rotation is horizontal in the longitudinal direction L.

By convention, the longitudinal and transverse orientations are determined in a fixed manner with respect to the base of the device so that the open or closed position of the device has no effect on said orientations.

The terms “left” and “right” will also be used without limitation with reference to the longitudinal orientation, as well as “upper” and “lower” or “top” and “bottom” with reference to the vertical orientation and finally “Front” and “rear” with reference to the transverse orientation, the front of the device having a means for gripping the cover in the closed position.

The terms “interior” or “exterior” and “internal” or “external” are respectively used in relation to the device in general and all particularly with respect to the intermediate part and to the base of the device, in particular to designate an element located either inside or outside the intermediate part or the base.

Although more particularly intended for the application of lipstick or lip balm, the invention can also be used for any other type of cosmetic product which can be packaged in solid or pasty form, that is to say which does not spread in the open air, in particular blush or eye shadow, foundation, perfume or deodorant or antiperspirant type products.

A first embodiment of a packaging device 10 according to the invention which is more particularly illustrated in FIGS. figures 1A to 7B .

The packaging device 10 is intended to be used for packaging a cosmetic product P, in particular a solid or pasty cosmetic product.

The device 10 for packaging a cosmetic product comprises a base 20, an intermediate part 30 intended to carry the cosmetic product P and a cover 40.

The intermediate piece 30 is mounted integral with the base 20 by means of fixing means. Preferably, the fixing between the intermediate piece 30 and the base 20 is obtained by cooperation of shapes, for example by elastic interlocking (or “clipping”).

As a variant, the fixing between the intermediate part 30 and the base 20 is made by screwing or gluing or any other equivalent fixing means.

The fixing means according to the first embodiment will be described in more detail later. The fixing means are able to bind axially at least, in the vertical direction, the intermediate part 30 and the base 20.

Depending on the fixing means used, the intermediate part 30 and the base 20 are also likely to be blocked or not in rotation with respect to one another.

The conditioning device 10 may comprise means for locking the intermediate part 30 in rotation relative to the base 20, separate from the fixing means.

In this first embodiment, the intermediate piece 30 is mounted in the base 20, the intermediate piece 30 being in part received inside the base 20.

The cover 40 is mounted to move in rotation with respect to the intermediate part 30, integral with the base 20, by means of articulation means. The cover 40 is mounted articulated on the intermediate part 30 so that the cover 40 occupies two positions, a first position, called the closing position of the device as illustrated in figures 1A to 1C , in which the base 20 and the cover 40 define a space that is substantially closed between them and a second position, called the opening position of the device as illustrated in figures 2A to 2C , in which the cover 40 is retracted inside the base 20.

Preferably, the device 10 is of substantially spherical shape. In a variant not shown, the device according to the invention can take a substantially cylindrical shape with rounded surfaces, the shape of an egg, oval or the like.

Preferably, the base 20, illustrated on figure 3A , is made of plastic chosen in particular from the group comprising acrylonitrile butadiene styrene (ABS), polypropylene (PP) or styrene-acrylonitrile (SAN). The base is made by molding.

The base 20 has substantially the shape of a hollow hemisphere and has an outer face 21 and an inner face 22. Advantageously, the inner face 22 is smooth. The outer face 21 may be smooth or may include reliefs. The outer face 21 can also be decorated, that is to say it can include elements for personalizing the device 10.

Along the vertical axis V, the base 20 has a first upper end 23 of the base 20 which is delimited circumferentially by an edge 123. This upper end 23 of the base 20 is open vertically upwards so as to receive the intermediate piece 30.

In addition, near the upper end 23 of the base 20 and more particularly on the inner face 22 of this upper end 23 of the base 20, there is a groove 24 designed to receive the intermediate piece 30. We find this again. groove 24 forming a shoulder over substantially the entire circumference of the base 20. The width of the groove 24, along the vertical axis V, is adapted to correspond to the width of a rim 31 of the intermediate part 30.

Along the vertical axis V, the base 20 also has a second lower end 25 of the base 20 allowing the gripping of the device 10 according to the invention during the application of makeup, the lower end 25 of the base 20 further comprising a structure 26 which, forming a bottom, is designed so as to allow the stable positioning of the device 10 on a complementary surface, for example a flat surface, in particular a make-up artist, a table, a counter.

The base 20 comprises at least two hooking means 27, here male, intended to cooperate with at least two hooking means 38, here female, provided on the intermediate part 30, so that the intermediate part 30 is integral with the base 20 in the closed and open positions of the device 10.

In this first embodiment, the hooking means 27 and 38 constitute an example of fixing means for fixing the intermediate part 30 and the base 20 together, reversibly or not.

As shown in figures 3A and 3B , each of the two male hooking means 27 located on the base 20 comprises, on the one hand, a centering device 28 and, on the other hand, housings 29, lateral with respect to the centering device 28.

The two male attachment means 27 are positioned substantially at the level of the groove 24. In other words, the two male attachment means 27 are located at the level of the inner face 22 of the upper end 23 of the base 20.

The centralizer 28 is intended to be housed in a recess 38-3 cut in the material of a head 38-1 of the female hooking means 38 of the part intermediate 30 so as to ensure the positioning of the intermediate part 30 on the base 20.

The centering device 28 can take any shape complementary to the shape of the recess 38-3. Thus, the technical form of the centralizer 28 is adapted so that it can be inserted or housed in the corresponding form of the recess 38-3. Advantageously, the technical form of the centering device 28, and consequently of the recess 38-3, is not of revolution so as to avoid any rotation of the intermediate part 30 relative to the base 20.

More particularly, the centralizer 28 can take a polygonal shape, in particular a substantially square, rectangular or triangular shape. Thus, the different sides created by the many angles in these polygons allow the non-rotation of the intermediate part 30 relative to the base 20.

As for them, the side housings 29 have a shape complementary to that of the tongues 38-2 of each of the female hooking means 38 of the intermediate part 30 so that the housings 29 and the tongues 38-2 cooperate together to maintain the intermediate piece 30 in position in the base 20.

The non-rotational shape of the centering device 28 and the presence of the lateral housings 29 at the level of the base 20 make it possible - when they cooperate respectively with the recess 38-3 and the tongues 38-2 of the intermediate part 30 - to avoid any rotation of the intermediate part 30 relative to the base 20.

In this first embodiment, the device 10 advantageously comprises means for locking in rotation which are also formed by the centralizer 28.

In a variant not shown, each of the two hooking means 27 located on the base 20 is a female hooking means intended to cooperate with one of the two male hooking means provided on the intermediate piece 30, so that the intermediate piece 30 is integral with the base 20 in the closed and open positions of the device 10.

According to the trihedron (L, V, T) represented in figure 1B , the two hooking means 27 are arranged longitudinally on the left and on the right relative to the base 20 of the device 10. Thus, the two hooking means 27 are positioned opposite one another longitudinally, diametrically opposed.

As shown in figures 1B , 2A and 2B , the device 10 comprises an intermediate part 30 intended to carry the cosmetic product P, which cosmetic product P is made accessible in the open position of the device 10.

Preferably, the intermediate part 30 is made of a plastic material chosen in particular from the group comprising acrylonitrile butadiene styrene (ABS), polypropylene (PP) or styrene-acrylonitrile (SAN). The intermediate piece 30 is produced by molding.

As illustrated in figures 4A to 4D , the intermediate part 30 comprises at least one rim 31 which has an outer face 32 and an inner face 33.

In this first embodiment, the intermediate piece 30 has the overall shape of a wheel.

The intermediate part 30 comprises radially inside retaining means which are intended to be engaged with the cosmetic product P, embedded in a block of solid or pasty cosmetic product P.

The intermediate piece 30 comprises a plurality of spokes 34 which extend from a hub 35 to terminate at the inner face 33 of the rim 31.

The spokes 34 extend from the hub 35 at equal angles to connect with the inner face 33 of the rim 31, in other words the spokes 34 are distributed circumferentially in a regular manner.

The spokes 34 and the hub 35 constitute the retaining means intended to be embedded, after casting, in a block of cosmetic product P in order to form a unitary sub-assembly.

The width of the spokes 34 and the diameter of the hub 35 are chosen so as to create an appropriate zone 36 onto which the cosmetic product P is poured here. This zone 36 on which the cosmetic product P is poured, is circular when the device 10 is substantially spherical. This zone 36 thus comprises a lower face 36-1 and an upper face 36-2.

The cosmetic product P is advantageously poured upside down on the zone 36 of the intermediate part 30, that is to say it is poured from the lower face 36-1 towards the upper face 36-2 of zone 36, using a hot pouring technique.

Thus the presence of interstices 37 between the spokes 34 determines at least one opening allowing the passage of the cosmetic product P through the intermediate part 30, the spokes 34 of which then make it possible to retain the cosmetic product P integral with the intermediate part 30.

In addition, along the vertical axis V, the zone 36 delimited by the rim 31 is set back relative to the height of the rim 31. The zone 36 is located at mid-height of the rim 31. For its part, the hub 35, is raised along the vertical axis V, that is to say that in side view as illustrated on figure 4A , it protrudes beyond an upper end of the rim 31 so as to stabilize the cast cosmetic product P.

In this first exemplary embodiment, the rim 31 and the means 35 are consequently not coplanar and the spokes 34 connecting them exhibit an inclination in the vertical direction.

As a variant, according to an embodiment not illustrated, the cosmetic product P can be poured via the upper face 36-2 of the zone 36 of the intermediate part 30. In this case, the zone 36 delimited by the rim 31 can be solid. , that is to say not to include spokes 34. To fix and stabilize the cast cosmetic product P, small notches are then present around the periphery of the inner face 33 of the rim 31.

The intermediate piece 30 further comprises at least two hooking means 38 located on the outer face 32 of the rim 31. The two hooking means 38 provided on the intermediate piece 30 are designed so as to ensure the positioning and maintaining the intermediate piece 30 in position in the base 20 on the one hand, and ensuring the tilting of the cover 40 around the axis of rotation (R) on the other hand, thus allowing the passage from the open position to the closed position of the device 10, and vice versa.

Each of the two hooking means 38 provided on the intermediate part 30 is a female hooking means. In a variant not shown, each of the two hooking means 38 provided on the intermediate part 30 can be a male hooking means.

As illustrated more particularly in figures 4B and 4D , each of the two female hooking means 38 provided on the intermediate part 30 comprises a head 38-1 and two tabs 38-2 located on either side of the head 38-1, as well as a recess 38-3 cut from the material of the head 38-1. The recess 38-3 is configured to accommodate one of the two male hooking means 27 of the base 20, and more particularly the centralizer 28 of the male hooking means 27.

The head 38-1 of the two hooking means 38 provided on the intermediate part 30 has a rounded shape. Preferably, the two hooking means 38 provided on the intermediate part 30 have the shape of an omega (Ω).

The head 38-1 of the two hooking means 38 provided on the intermediate part 30 has a thickness, measured along the longitudinal axis L, sufficient to allow passage of the cover 40.

The thickness of the cover 40 allows the latter to tilt in a rotational movement around an axis (R) of rotation defined by at least two hooking means 38 located at the level of the intermediate part 30 and forming means of hinge of the cover 40.

More particularly, the tilting by rotation takes place via the head 38-1 of the hooking means 38 so that the cover 40 can be housed in the base 20 of the device 10.

The intermediate part 30 further comprises locking means allowing the cover 40 to be retained in the open position - reciprocally in the closed position.

As shown on figures 4A to 4E as well as 6A, 6B, 7A and 7B, the locking means are provided in the form of at least one protuberance 39 of material projecting from the intermediate part 30.

Said at least one protuberance 39 of material is intended to cooperate with the cover 40, the passage from the closed position to the open position, and vice versa, taking place by a limited force exerted on the cover 40, so in unlocking the cover 40 from its position, advantageously without using an external tool.

In this first embodiment, the intermediate piece 30 comprises a protuberance 39 of material which has the overall shape of a hook as illustrated in the figure. figure 4E .

According to the trihedron (L, V, T) represented in figure 1B , the two attachment means 38 are arranged longitudinally, respectively to the left and to the right relative to the intermediate part 30 of the device 10, as are the attachment means 27 relative to the base 20. The two means of hooks 38 are thus positioned opposite each other longitudinally, diametrically opposed. For its part, the protrusion 39 of material protrudes from the outer face 32 of the rim 31, and more particularly the protrusion 39 of material is located transversely to the rear of the outer face 32 of the rim 31.

Aesthetically, the tabs 38-2 and the corresponding lateral housings 29 are invisible to the eye of the user when the cosmetic product P is used, because they are hidden in the base 20 of the device 10.

As shown in figures 1A and 2A , the device 10 comprises a cover 40 which is mounted movable in rotation on the intermediate part 30.

The cover 40 is hinged so as to occupy two positions, a first position, called device closure 10, in which the base 20 and the cover 40 define a substantially closed space between them and a second position, called the opening of the device. 10, in which the cover 40 is retracted, by a rotational movement about an axis (R) of rotation, inside the base 20.

In addition, the cover 40 is configured to be locked in the open position and vice versa in the closed position of the packaging device 10.

Preferably, the cover 40 is made of a plastic material chosen in particular from the group comprising acrylonitrile butadiene styrene (ABS), polypropylene (PP) or styrene-acrylonitrile (SAN). The cover 40 is made by molding.

As illustrated in figures 5A to 5C , the cover 40 has substantially the shape of a hollow hemisphere and has an outer face 41 and an inner face 42.

Advantageously, the inner face 42 of the cover 40 is smooth. The inner face 42 is devoid of relief so as not to damage the surface of the cosmetic product cast and housed inside in the closed position of the device 10.

However, the inner face 42 of the cover 40 has a notch 47 intended to receive at the end of the stroke of the cover 40 the protrusion 39 of material projecting from the intermediate part 30, so as to retain the cover 40 in the open position.

More particularly and as illustrated on figure 5C , the notch 47 is located on the inner face 42, transversely to the front of the cover 40 in the closed position of the device 10.

The outer face 41 can be smooth or can include reliefs. The outer face 41 can also be decorated, that is to say it can include elements for personalizing the device.

Along the vertical axis V, the cover 40 has a first end, called the upper end 43 of the cover 40. This upper end 43 of the cover 40 is closed.

Along the vertical axis V, the cover 40 has a second end, called the lower end 44 of the cover 40. This lower end 44 of the cover 40 is open so as to be able to cover and protect the cosmetic product P in the closed position of the cover. device 10.

The notch 47 is positioned in the vicinity of an edge 144 of the lower end 44 of the cover 40.

Near the lower end 44 of the cover 40 and more particularly transversely to the front on the outer face 41 of this lower end 44 of the cover 40, there is a gripping means 45 intended to allow handling of the cover 40.

The gripping means 45 is advantageously used to cause the cover 40 to pass from its open position to its closed position, and vice versa.

In this first embodiment, the gripping means 45 forming a handle here take the form of a hook, substantially in the shape of an “L”.

The gripping means 45 is able to come to bear, here on the base 20.

The gripping means 45 is intended to serve as a stopper to block the travel of the cover 40 in the closed position as in the open position, by contact with the edge 123 of the base 20.

The cover 40 is configured to tilt according to a rotational movement about an axis (R) of rotation defined by at least two hooking means 38 forming the articulation means located on the intermediate part 30.

More particularly, the tilting by rotation of the cover 40 takes place via the head 38-1 of the hooking means 38 so that the cover 40 can be housed in the base 20 of the device 10, that is to say to inside the base 20.

The cover 40 has two connection zones 46. The two connection zones 46 located on the cover 40 each have a shape complementary to that of the head 38-1 of the female hooking means 38 located at the level of the intermediate part 30, so as to ensure the articulation of the cover 40 on the intermediate part 30 and to allow the tilting of the cover 40 from the closed position to the open position, and vice versa.

Furthermore, the particular shape of the hooking means 38, that is to say the omega (Ω) shape, helps to assemble the cover 40 on the hooking means 38 of the intermediate part. 30.

The omega (Ω) shape thus reduces the risk of breaking the end of the connecting zones 46 located on the cover 40 during the insertion of the hooking means 38 in the connecting zones 46, while allowing the articulation of the cover 40 on the intermediate piece 30, thanks to the rounded shape of the head 38-1 which matches the complementary shape of said connecting zones 46 of the cover 40.

According to the trihedron (L, V, T) represented in figure 1B , the two connection zones 46 are arranged longitudinally to the left and to the right relative to the cover 40 of the device 10, as are the male attachment means 27 relative to the base 20 and the female attachment means 38 relative to to the intermediate piece 30.

Thus, the two connecting zones 46 are positioned opposite one another longitudinally, diametrically opposed. The gripping means 45 is arranged perpendicularly to one or the other of the two connection zones 46 on the cover 40, here in the middle between the two connection zones 46.

Finally, the notch 47 and the protuberance 39 of material are located opposite one another, along the transverse axis (T), in the closed position of the device 10, otherwise known as the notch 47 and protrusion 39 of material are diametrically opposed in the closed position of device 10.

As illustrated in figures 6A and 6B , in the closed position of the device, the protuberance 39 of material is in abutment with the cover 40.

The cover 40 is thus locked in the closed position thanks to the protuberance 39 of material which cooperates with the cover 40 to retain it in the closed position. Note also that the notch 47 is located transversely at the front of the device 10, on the inner face 42 of the cover 40, in the vicinity of the edge 144.

Advantageously, the passage from the closed position to the open position is effected by a limited force, exerted on the cover 40, so as to unlock the cover 40 from its initial position. The user unlocks the cover 40 by means of the gripping means 45 located transversely to the front in the closed position of the device 10.

During the gradual tilting of the cover 40 inside the base 20, from the closed position to the open position, the protrusion 39 of material, projecting from the intermediate piece 30, is in continuous abutment with the face interior 42 of the cover 40.

Thus, a continuous stress is exerted between the protuberance 39 of material and the inner face 42 of the cover 40, during the tilting of the cover 40 from the closed position to the open position.

During the operation of the cover 40, between the closed and open positions, the protuberance 39 of material cooperates with the inner face 42 of the cover 40.

As shown on figure 4E , the protrusion 39 of material is constituted by a tab made integrally from the intermediate part 30. Thus during the operation of the cover 40, a stress is permanently exerted on the tab comprising the protrusion 39 of material, said constraint ceasing to be exerted when one or the other of said closed or open positions is reached by the cover 40.

Thanks to the stress and friction exerted between the protrusion 39 of material and the inner face 42 of the cover 40, the tilting movement of the cover 40 is controlled during its movement between the closed and open positions and reciprocally.

In fact, when the open position of the cover 40 is reached, for example, the protuberance 39 of material is then received in the notch 47 made recessed in the inner face 42 and ceases to be constrained.

The cover 40 is then blocked in the open position by the protuberance 39 of material when the maneuver in the opposite direction, to switch the cover 40 from the open position to the closed position, can only be carried out. 'by applying on cover 40 a sufficient force to cause the protuberance 39 of material to come out of the notch 47 by putting it again under stress against the inner face 42 of the cover 40.

Of course, what has just been described for the opening maneuver of the cover 40 of the device 10 also applies to the closing maneuver.

At the end of the stroke of a closing maneuver, the protrusion 39 of material ceases to be constrained when it crosses the edge 144 of the lower end 44 of the cover 40 and the locking of the cover 40 is then obtained.

Indeed, the user must then apply a sufficient force on the cover 40 so that the protrusion 39 of material crosses again the edge 144 of the cover 40 and that, in contact with the inner face 42, said protuberance 39 of material carried by the leg is under stress.

As illustrated in figures 7A and 7B , in the fully open position, that is to say when the cover 40 has finished its stroke and is retracted inside the base 20, the gripping means 45 determines the stopping of the stroke of the cover 40 by coming to rest at the rear of the device on the edge 123 of the base 20.

The protrusion 39 of material, which is no longer in abutment against the inner face 42 of the cover 40, is then located inside the notch 47 which allows the cover 40 to be blocked in the open position.

To effect the passage from the open position to the closed position, the user must apply a force preferably by means of the gripping means 45 to unlock the cover 40, that is to say to cause the exit of the protuberance 39 of material out of the notch 47.

The protuberance 39 of material is then again in continuous abutment with the inner face 42 of the cover 40, until the gripping means 45 comes to bear at the front of the device on the edge 123 of the base 20.

At this moment the protuberance 39 of material resumes its starting position, that is to say that it is in abutment with the cover 40, as illustrated in figures 6A and 6B , positioned under the edge 144 of the cover 40.

In this first embodiment, the cover 40 is consequently capable of occupying at least one intermediate position between said closed and open positions.

The intermediate position is a stable position, the cover 40 being held in position by friction due to the force applied by the protuberance 39 against the inner face 42 of the cover 40.

A second embodiment according to the invention of a device 10 for packaging a cosmetic product P, in particular for a solid or pasty cosmetic product, will be described below.
