Description

DESCRIPTION

TITLE: APPLICATION KIT INCLUDING AN APPLICATOR AND A PACKAGING DEVICE

Technical area

This disclosure relates to a packaging device, and more particularly a packaging device capable of containing a product, typically liquid, pasty or pulverulent, which can be applied by means of an applicator. Such a packaging device can in particular find its application in the field of cosmetics, which includes perfumery.

Prior art

[0002] Certain cosmetic or care products, such as mascaras, are generally applied by means of an applicator having a relatively long rod. This rod allows the applicator to be fully immersed in the container to impregnate it with product, but limits the precision of the application gesture.

[0003] It would therefore be advantageous to be able to offer a new application gesture. However, the shortening of the rod required by this new gesture is incompatible with the containers currently available. Therefore, there is a need for a new packaging device.

Disclosure of the invention

To this end, the present disclosure relates to a packaging device for a cosmetic product, comprising a body, a piston movable relative to the body and a reservoir, configured to contain the cosmetic product, housed between the body and the piston and having a bottom and an opening, the opening opening onto the outside of the body and allowing the passage of an applicator member, one among the opening and the bottom being integral with the body and the other among the opening and the bottom being integral with the piston so as to allow the opening and the bottom to be brought together, a return element being mounted between the body and the piston to assist the relative movement between the bottom and the opening at least in one direction . In the present description, bringing the opening and the bottom closer means bringing the opening closer to the bottom or the bottom of the opening, indifferently, depending on the chosen frame of reference, it being understood that a frame of reference associated with the body is generally chosen, in which the body is fixed and therefore the piston is mobile.

To say that the bottom is integral with the body or the piston so as to allow the opening and the bottom to come together means that in the relative movement of the piston with respect to the body, the body or the piston is likely to cause a movement of the bottom relative to the opening, at least in one direction, in particular in the direction allowing the opening and the bottom to be brought together.

[0007] The return element can be an elastically deformable element, mounted in tension or in compression, and used in the manner of a spring.

[0008] For example, the return element can be configured to oppose the approach of the opening and the bottom, thus assisting the movement away from the opening and the bottom. In these embodiments, the action of the user to bring the opening and the bottom closer together allows the applicator member to reach the product even if the reservoir is not full. Then, the return element moves the opening and the bottom away again so that the product does not overflow from the reservoir when the applicator member is withdrawn. Such an example is particularly suitable when the product is liquid or pasty.

[0009] According to another example, the return element can be configured to assist the bringing together of the opening and the bottom. Thus, the return element tends to ensure that the product, which a priori stagnates at the bottom of the reservoir, is always located near the opening and therefore accessible for the applicator member. Such an example is particularly suitable when the product is not at risk of overflowing, typically when the product is solid, for example in powder form.

Whatever the example, by passing the applicator member through the opening of the reservoir, the user impregnates the applicator member with product. The ability to bring together and the return element make the product more accessible for the applicator member, which offers greater freedom for the design and sizing of the applicator member. In particular, it is possible to do without a long rod, as will be seen below, which offers the user a new application gesture. In some embodiments, the piston is movable in translation relative to the body. The translation can take place along the axis of the opening of the reservoir. The body and / or the piston may be provided with a guide element to maintain the relative orientation of the body and the piston during translation.

In some embodiments, the opening is integral with the piston and the opening is oriented so that pressure from an applicator carrying the applicator member against the opening causes movement of the piston in the direction from the bottom of the tank. Said movement may be the aforementioned translation. In these embodiments, when the user presses the applicator against the opening, this exerts pressure on the piston which starts to move in a direction towards the opening and the bottom. Thus, the applicator member can be brought into contact with the product present at the bottom of the reservoir.

In certain embodiments, the conditioning device comprises locking means configured to block the movement of the piston tending to bring the opening and the bottom closer together. Thus, the approximation movement cannot be carried out in an untimely manner, which could cause the tank to overflow. The reliability of the conditioning device is therefore improved.

Thus, in certain embodiments, the piston is movable between a free configuration in which the movement of the piston relative to the body to bring the opening and the bottom closer together is possible, and a locked configuration in which the movement of the piston relative to the body to bring the opening closer and the bottom is blocked. For example, the passage of the piston from the free configuration to the locked configuration can be effected by a movement of the piston in a plane orthogonal to the direction of approach between the opening and the bottom, for example a rotation. Alternatively or in addition, the locking of the piston can be controlled by the installation of a retractable stop which or not blocks the movement of the piston. Other forms of locking means can be envisioned by those skilled in the art.

In some embodiments, the packaging device comprises a wringer mounted on the passage of the applicator member through the opening. It is understood that the wringer can be mounted in the opening or well before or after opening, so that when the applicator member is withdrawn from the reservoir and passes through the opening, it also passes through the wiper. The wringer makes it possible to limit the quantity of product on the applicator member, in particular in order to avoid drops and clumps.

The wiper may include a conventional wiper member of the mascara wiper type, for example provided with a tubular membrane or blades, flexible or not, configured to scrape the applicator member, optionally by penetrating therein. . According to other embodiments, the wiper can also be produced via a foam, a sieve, a mesh or any other means for wringing-wiping the applicator and / or measuring the quantity of product on the applicator, which can be envisaged by the person skilled in the art.

In some embodiments, the reservoir is deformable, in particular by comprising a pocket configured to contain the product, and capable of being deformed by the movement of the piston relative to the body. Thus, the bag is relatively flexible, for example in materials such as low density polyolefins. The pouch containing the product seals the inside of the body. The deformation of the bag, or more generally of the reservoir, helps the circulation of the product in the reservoir, so that the product can be brought closer to the opening.

In some embodiments, the packaging device comprises a cover configured to adopt a closed position in which the cover covers a part of the body on which the opening opens. The cover can be provided with sealing means with the body, which are functional at least in the closed position.

Furthermore, the cover can be assembled to the body at least in the closed position. Thus, in some embodiments, the cover is hinged to the body by a hinge. In other embodiments, the cover can be connected to the body by screwing, clipping or any other removable means that can be envisaged by those skilled in the art.

[0020] In certain embodiments, the body comprises a removable base to allow the reservoir to be recharged with product other than through the opening. This results in a considerable saving of time when loading product, the achievable filling rate being much higher. In addition, the rechargeable nature of the packaging device makes it attractive both from an ecological and economic point of view for the user.

This disclosure also relates to an application assembly comprising a packaging device as described above, and an applicator comprising an application member. The applicator may also include a gripping member linked to the applicator member, the gripping member serving for the user to hold the applicator. The gripping member and the applicator member may or may not be removable from one another.

In some embodiments, the cover is configured to cooperate with the applicator so that, when the cover is in the closed position, the cover holds the applicator against the opening. The applicator held against the opening can block the opening in order to ensure, in the closed position, the complete sealing of the reservoir. Thus, sealing means can be provided between the applicator and the opening, for example around the periphery of the opening and / or on a sealing portion of the applicator.

[0023] Alternatively, the sealing at the opening may be assisted by other means for holding the applicator against the opening than the cover, for example mechanical snap-fastening means, magnetic means or any other means. another means of attachment that can be envisaged by those skilled in the art (screwing, strapping, clipping, etc.).

In certain embodiments, the cover comprises a first keying part configured to cooperate with a second keying part provided on the piston or on the applicator. Thus, when the cover is in the closed position, the keying parts cooperate to ensure that the piston or the applicator is in a certain position and / or orientation, it being understood that in the closed position, the cover can have a position and / or orientation a predefined orientation with respect to the body. The position and / or the orientation of the piston and / or of the applicator can intervene in the previously mentioned locking means. In these embodiments, closing the cover therefore guarantees locking of the piston and consequently prevents the risk of overflowing. The polarizer can be an angular polarizer. In some embodiments, the applicator member extends mainly transversely with respect to the axis of the opening. In these embodiments, the applicator member has its main dimension, that is to say its largest dimension, which extends transversely to an axis passing through the opening, said axis being for example the direction of passage of the applicator through the opening. Thus, a larger surface of the applicator member can be brought into contact with the product.

In some embodiments, the aforementioned gripping member may be in the general shape of a ring. Thus, the user can grasp the applicator by inserting her finger into the gripping member, which is an example of a new application gesture permitted by the subject of the present disclosure.

detailed description

In the present description, the terms upper, lower, top, bottom are to be understood in a relative sense only. They make it possible to distinguish two essentially opposite locations, with reference to the orientation of the figures. However, in particular, the line connecting a point "High" to a "low" point is not necessarily vertical in the usual sense of the term and may depend on the orientation of the application assembly in space.

An application assembly 100 according to a first embodiment is described with reference to Figures 1 to 3. As illustrated, the application assembly comprises an applicator 140 and a packaging device, itself comprising here a body 110 which can be closed by a cover 160. The body 110 is shown partially in transparency in FIG. 1.

The body 110 is here substantially tubular around an axis X, and more particularly cylindrical with a circular, elliptical or other base. The body 110 can be closed at one end (lower end in Figures 1-3), in this case removably. In this embodiment, the body comprises a base 112 closing off said end. The base 112 can be assembled to the rest of the body 110 in various ways, in this case by interlocking. A latching lug 112a may be provided to ensure that the base 112 is held in relation to the rest of the body 110. The base 112 is here generally flat but may have other shapes, for example a concave shape allowing the product to be brought together. cosmetic contained in the body 110 towards the center of the body 110 or any other desired region.

The conditioning device further comprises a piston 120 movable relative to the body 110. The piston 120 can be movable in translation relative to the body 110, typically along the X axis of the body. Thus, the piston 120 slides in the body 110. The outer shape of the piston 120 can be substantially complementary to the inner shape of the body 110, in particular in a plane transverse to the X axis, so that the piston 120 visually gives the impression of closing the end of the body 110 opposite to the base 112, as is apparent from FIG. 1. Furthermore, the piston 120 can be substantially undeformable, that is to say have an invisible or negligible deformation at the naked eye during normal use of the application set 100.

The packaging device also comprises a reservoir 130 configured to contain a product such as a cosmetic product (which includes perfumes or the like), in this case a liquid, pasty or powdery product such as a mascara, an eye shadow, a blush, an eyeliner, a foundation, a care cream, a serum, a moisturizer, a product anti-wrinkle, a gloss, a perfume, a self-tanning formula or any other formula which can be envisaged by a person skilled in the art in the perfume and cosmetics sector. As can be seen in Figures 2 and 3, the reservoir 130 is housed between the body 110 and the piston 120, in particular in the direction of the X axis. More precisely, the reservoir 130 is housed between the base 112 and the piston. 120.

The reservoir 130 has a bottom 131 and an opening 132. In this embodiment, the opening 132 is integral with the piston 120. More precisely, the opening 132 is made in the piston 120 and opens to the outside. of the body 110. The opening 132 is therefore movable, with the piston 120, relative to the body 110. In this embodiment, the opening 132 is non-circular, for example generally elliptical or oval.

Furthermore, in this embodiment, the bottom 131 is integral with the body 110. In this case, the bottom 131 can be placed or even fixed on the base 112 of the body 110. Thus, the base 112 serves at least stop at the bottom 131 to limit the travel of the bottom 131 when the piston 120 approaches the base 112. As a result, the translational movement of the piston 120 relative to the body 110, here towards the base 112, makes it possible to bring the bottom closer 131 and the opening 132 from each other.

In this embodiment, the reservoir 130 is deformable, typically under the influence of the movement of the piston 120 relative to the body 110. To this end, for example, the reservoir 130 comprises a pocket configured to contain the product. The pocket forms an open envelope in which the product is contained. The pocket may be of a relatively flexible material so as to be able to be elastically deformed. The bag can have a monolayer or multilayer structure, the material (s) being chosen by a person skilled in the art according to his knowledge, taking into account the desired mechanical properties and the physicochemical compatibility with the product contained inside. the pocket.

The pocket is open to the opening 132 of the reservoir 130. In this embodiment, the pocket is assembled with the piston 120, the volume of the reservoir 130 therefore being defined between the piston 120 and the pocket. For example, the piston 120 can include a skirt 128 projecting in the direction of the reservoir 130. The skirt 128, here annular, can be provided with a thread or other fastening means. A ring 134, to which the pocket is assembled, may include a complementary thread 134a configured to screw onto the skirt 128. Thus, the ring 134 secures the opening of the pocket, and therefore of the reservoir 130, to the piston 120.

The pocket can be assembled to the ring 134 by various means, for example welding, gluing, etc. The ring 134 may have, as illustrated, an annular groove to facilitate the attachment of the pocket. The pocket could also be pinched on the ring 134, or even between the ring 134 and the skirt 128. Also alternatively, the ring 134 could be made in one piece with the pocket, or even integral with the pocket, which can be achieved for example by a technique of injection blow molding, extrusion blow molding or co ^¬ extrusion blow molding.

The use of a product bag and a base 112 separate from the rest of the body 110 allows the bag already filled in the device to be mounted by the lower end of the body 110. It is therefore no longer necessary , as is conventionally done, to carry out the initial loading of product through the dispensing opening, which would here be equivalent to the opening 132. In other words, the base 112 removable from the body 110 allows the tank to be loaded or reloaded. 130 produces it other than through the opening 132.

In addition, thanks to the fact that the base 112 can be removed from the body 110 and that the assembly of the pocket on the piston 120, here via the ring 134, is reversible, an empty pocket can be replaced by a pocket full. More generally, the packaging device can be recharged with product.

As indicated above, the conditioning device comprises a return element mounted between the body 110 and the piston 120 to assist the relative movement between the bottom 131 and the opening 132 at least in one direction. In this case, at least one spring 136 is provided, here mounted in compression between the base 112 and the piston 120. The spring 136 is configured to oppose the approach of the opening 132 and the bottom 131, therefore to assist the movement away from the opening 132 and the bottom 131. In other words, the body 110 being assumed to be stationary, the spring 136 tends to return the piston 120 upwards. The stroke of the piston 120 in the direction away from the opening 132 of the bottom 131 can be limited by a stop 126 of the piston, projecting radially and cooperating axially with a corresponding stop 116 of the body 110 (see FIG. 3).

The position of the piston 120 illustrated in Figures 1 to 3 therefore represents the position in which the opening 132 is as far as possible from the bottom 131. When the piston 120 translates downwards, the opening 132 approaches the bottom 131 and the spring 136 compresses further to oppose this movement and return the piston 120 to its original position.

Rather than taking the form of a separate element such as the spring 136, the return element could form part of another element. For example, the pocket of the reservoir 130 could comprise a side wall in the form of an accordion or bellows, the bellows being dimensioned to exert a restoring force opposing the approach of the bottom and the opening. According to another example, the return element could be integral with the piston 120.

Despite the presence of the return element, that is to say in this case of the spring 136, in order to avoid unwanted movements of the piston 120, it can be provided locking means configured to block the movement of the piston 120 tending to bring the opening 132 and the bottom 131 closer together. In this case, the piston 120 comprises at least one protuberance, here two diametrically opposed ledges 127. In the direction of approach of the opening 132 and the bottom 131 (direction of the axis X, here, and direction of translation of the piston 120), the ledges 127 are arranged opposite the stops 126 of the piston with respect to the stops 116 of the body 110. Thus, in the configuration illustrated in FIG. 3, the ledges 127 abut axially against the stops 116. The piston 120 is then in the locked configuration.

In order to move the piston 120 in free configuration, it is possible to make it undergo a rotation, for example a quarter turn, so that the cornices 127 no longer face, axially, the stops 116 (see figure 2, which shows the absence of stops 116 on the body 110 in the plane II-II). Thus, the piston 120 becomes free to perform its translational movement along the X axis relative to the body 110. The piston 120 is however always limited in its upward stroke, for example thanks to the fact that the stop 126 is annular. and therefore still comprises, despite the rotation, a portion configured to abut against the stops 116 of the body.

As illustrated in Figures 1 to 3, the opening 132 allows the passage of an application member 150. The previously mentioned applicator 140 in fact comprises an application member 150 and a gripping member 142. The gripping member 142 and the applicator member 150 can be formed in one piece or, as shown in Figure 2, assembled to each other, here in a removable manner, for example by complementarity of shapes and interlocking (see the attachment portion 148). Thanks to this characteristic, the user can have a single gripping member 142 adapted to her body language and / or her morphology, and a plurality of application members, each producing a different application effect.

The applicator member 150 may comprise a brush or a comb, a flocked tip, a silicone tip, a foam tip or more generally a tip provided with bristles or pins 146, arranged in row (s) or not. , for the application of the cosmetic product. For example, the pins 146 may extend, when the applicator 140 is inserted into the opening 132, parallel to the X axis of the opening 132. From another point of view, the applicator member 150 may extend mainly transversely to the X axis of the opening 132, as shown in Figures 2 and 3. The shape, length, position, orientation and stiffness of the bristles or pins 146 may be adapted by those skilled in the art according to their general knowledge as a function of the desired application effect. The brush may optionally comprise bristles or spikes distributed circumferentially around an axis and extending in a radial direction around this axis, the brush being mounted to rotate with respect to this axis and driven in rotation during the application movement, typically by friction with the part of the body concerned, for example the eyelashes.

Other applicator members can comprise woven or non-woven fibers, flocking, and the like. The applicator member 150 can be mono-material or multi-material.

The gripping member 142 is, in this embodiment, in the general shape of a ring. In this case, it comprises two curved wings 144a, 144b, intended to accommodate between them a finger of a user. The wings 144a, 144b can be configured to deform elastically during the insertion of the finger, in order to ensure good retention of the gripping member 142 on the finger.

[0054] Furthermore, the gripping member 142 can offer geometric adaptability to the user, for example by being flexible and / or configured to adapt to the morphology of the user. For example, the gripping member 142 can deform plastically to adopt a rest position suitable for the user, independently of the elastic deformation. aforementioned; in this case, the wings 144a, 144b can be moved away from or brought closer to one another to define a passage having the desired area, typically corresponding to the diameter of the user's finger.

The wings 144a, 144b may have a free distal end, for example opposite the attachment portion 148. Said free distal ends may be circumferentially separated from one another by a space.

The applicator assembly can be configured to seal the reservoir 130 when the applicator member 150 passes through the opening 132. In this case, the opening 132 is provided with a seal. seal 122, here an annular seal of cross section in the general shape of a U, the interior of the U-shaped section receiving the piston 120. The interior shape of the seal 122 may correspond substantially to the exterior shape of the piston. applicator 140, here the applicator member 150. A conical contact, typically around the X axis, can be provided between the applicator member 150 and the seal 122, so as to ensure a seal increasing as the applicator 140 is inserted into the opening 132.

Furthermore, the applicator 140 may include a sealing lip 151, here projecting radially from the applicator member 150. The lip 151 may come into contact with a side branch of the U-shaped section of the seal. seal 122. Thus, the lip 151 improves the seal in a direction different from that in which the applicator member 150 cooperates with the seal 122, in this case in a plane contact perpendicular to the X axis.

In addition, as indicated above, the conditioning device may include a wringer 124 mounted on the passage of the applicator member 150 through the opening 132. The wringer 124 may, in particular, be mounted on the passage of the bristles or pins 146 in order to remove therefrom the excess of cosmetic product. In the present embodiment, as shown in FIG. 2, the wiper 124 comprises two scrapers positioned on either side of the applicator member 150 when the applicator member passes through the opening 132. In this case, the scrapers project from the seal 122 towards the interior of the reservoir 130, but other arrangements are possible. The wringer 124 can form a single piece with gasket 122, as shown, but could be a different part from gasket 122.

Although the opening 132 is shown free in this embodiment, it is possible, as a variant, to provide an interface between the inside and the outside of the reservoir 130. For example, the opening 132 can be closed by a porous interface such as a canvas, a net, a foam, etc., capable of allowing the cosmetic product to pass, or even of allowing the applicator member to penetrate into the reservoir 130. The porous interface may, in these variants, play the role of wringer 124.

The cover 160 mentioned above is configured to adopt a closed position, illustrated in Figures 2 and 3, as opposed to the open position shown in Figure 1. In the closed position, the cover 160 covers part of the body 110 on which opens the opening 132. In this embodiment, the cover 160 has a generally tubular shape in the extension of the body 110, at least in the closed position.

The cover 160 can be articulated relative to the body 110 by a hinge 162. However, the cover 160 could be secured to the body 110 in other ways, for example clipped, screwed, and the like. In the case of a hinge, a mechanism 166 for maintaining the cover in the closed position is shown in FIG. 3. This maintaining mechanism 166 is known per se and will not be described further. Other retention mechanisms can be considered.

As indicated above, the cover 160 comprises a first keying part configured to cooperate with a second keying part provided on the piston 120 or on the applicator 140. In this case, the first keying part is formed by a blade 164, projecting from the bottom of the cover 160 along the X axis. The blade 164 is of generally planar shape, in any case not axisymmetric around the X axis. Furthermore, the second keying part can be formed by the wings 144a, 144b of the applicator 140, and the space between them. Thus, in the closed position shown in FIG. 2, the blade 164 enters the space separating the wings 144a, 144b and prevents, by its geometry, the applicator member 140 from rotating around the X axis. This ensures that the piston 120, which carries the applicator 140, is indeed and remains in the locked configuration described above when the cover 160 is closed. Alternatively, the second keying part could be provided on the piston 120, for example in the form of a protuberance or a recess with which the blade 164, or any other part of the cover 160, could cooperate. In particular, the protrusion or the recess may be non-annular and / or eccentric.

[0064] In addition, the cover 160 is configured to cooperate with the applicator 140 so that, when the cover 160 is in the closed position, the cover 160 maintains the applicator 140 against the opening 132. In this case , the blade 164 is sized to press the applicator 140 when the cover 160 is in the closed position. Thus, in this position, the applicator 140 is sandwiched between the blade 164 and the piston 120, on which it rests for example via the sealing lip 151 and / or the conical contact with the seal 150. The seal is therefore maintained.

In this embodiment, the keying function and the sealing function are performed by the same element, namely the blade 164. However, these functions could be separated. For example, sealing does not require a blade, the cover 160 being able to be dimensioned so that the bottom of the cover 160 bears directly on the free ends of the wings 144a, 144b in order to elastically hold the applicator 140 against the piston 120. In this way, furthermore, the keying function could be achieved by the presence of a cell in the cover, able to receive part of the applicator 140, for example the free ends of the wings 144a, 144b, in the desired orientation.

The cover 160 can still have other functions. For example, there may be provided, typically on the bottom of the cover, one or more supports configured to each receive a different applicator member. Thus, different application members are available at the same time for the user, the latter being able to grasp one or the other by virtue of a common gripping member or not. The supports can take the form of cells of shape corresponding to those of the applicator members, for example in a relatively compact foam. The cells themselves can provide a certain seal to prevent the remainder of product on the applicator members from flowing. Alternatively or in addition, an additional seal can be provided around the perimeter of the cover 160. From the closed position of the cover 160 shown in Figures 2 and 3, the operation of the packaging assembly can be as follows. The user activates the holding mechanism 166 to release the cover 160, then opens the cover 160, for example by swinging it around the hinge 162. This releases the blade 164 from the applicator 140, as shown in FIG. 1. The user can then grasp the gripping member 142 or insert her finger therein, then cause the applicator 140 to make a quarter turn around the X axis, which causes the piston 120 to rotate from the locked configuration to free configuration. The user can then exert pressure on the applicator 140 against the opening 132 and the piston 120, which causes movement of the piston 120 in the direction of the bottom 131 of the reservoir 130. The applicator member 150 thus approaches. of the product and the bristles or pins 146 are impregnated with the product. This approximation may be accompanied by a crushing of the reservoir 130, in this case the bag, which has the effect of better distributing the product in the reservoir 130, in particular to spread the product contained on the sides towards the bottom. center of the reservoir 130, facing the opening 132. The quantity of accessible product is therefore increased.

When the pressure is released, the spring 136 returns the piston 120 upwards, moving the opening 132 away from the bottom 131. Thus, the user can remove the applicator 140 from the opening 132 without risk of the overflow of the reservoir 130. When passing through the opening 132, during withdrawal, the wiper 124 wrings the applicator member 150, in particular the bristles or pins 146. Having grasped the gripping member 142, the user can perform a movement of application. Thanks to the fact that the gripping member 142 is relatively short, the applicator member 150 is closer to the hand and the application gestures are both more user-friendly and more precise.

Once the application is complete, the user can reintroduce the applicator member 150 through the opening 132, then engage the locking means, in this case by a rotation of the applicator 140 causing a rotation of the piston 120. Without this rotation, the orientation of the applicator 140 prevents the cover 160 from being closed, the blade 164 abutting against the wings 144a, 144b. Thus, the user is obliged to lock the piston 120 before closing the cover 160. Once the cover 160 is in the closed position, the cover 160 and more particularly the blade 164 holds the applicator 140 against the piston 120. Figures 4 and 5 show the application assembly in a second embodiment. In these figures, the elements corresponding or identical to those of the first embodiment will receive the same reference sign, to the nearest hundreds, and will not be described again.

In this second embodiment, the conditioning device differs from the first embodiment in particular in that the body 210 has its upper end closed by a wall 214 rigidly fixed to the rest of the body 210, and in which the body 210 is provided. 'opening 232. Thus, the opening 232 is integral with the body 210.

The piston 220 is mounted to be movable relative to the body 210, in this case movable in translation along the X axis between the base 212 and the wall 214. It is noted that the base 212 has an alternative fixing method with respect to to the rest of the body 210, here using a thread 212a.

The reservoir 230 is still provided between the body 210 and the piston 220, but here between the wall 214 and the piston 220, and no longer between the base 212 and the piston 220. Thus, in this embodiment, the bottom 231 of the reservoir 230 is integral with the piston 220, at least in translation along the X axis.

In this embodiment, the cosmetic product is provided in the form of a compact powder, for example for foundation, blush, or else in the form of cast wax, for example for gloss, eye shadow, concealer, perfume balm , care balm (for example moisturizing, anti-wrinkle or other), etc. Thus, the reservoir 230 is formed by a block of product which maintains its shape on its own, without it being necessary to provide a container of any type whatsoever. However, a reservoir 230 having a physical delimitation such as a pocket may however be provided, for example to limit exposure to air and contamination of the product.

A return element, here comprising leaf spring 236, is mounted in compression between the piston 220 and the body 210, more particularly between the pison 220 and the base 212. The leaf spring 236 may or may not be fixed to the piston 220 and / or to the base 212 and, independently, fixed or not to each other.

The leaf springs 236 assist the movement of the bottom 231 of the reservoir 230 towards the opening, so that the product contained in the reservoir is always accessible to the applicator member 250, although the opening 232 is stationary relative to the body 210. In other words, the piston 220, pushed by the spring blades 236, brings the product closer to the opening 232 - and therefore to the applicator member 250 - as said product is consumed.

In this embodiment, the stops 116, 126, the ledges 127 and the locking means are therefore not necessary, the position of the piston 220 being controlled by the remaining quantity of product in the reservoir 230. In addition, the movement of bringing together the bottom 231 and the opening 232 takes place automatically, without the user needing to actuate the piston 220 directly or indirectly via the applicator 240.

Note that the gripping member 242 has a different shape configured to fit between two fingers of the user. To do this, the gripping member has concavities 242a aimed at matching the shape of two adjacent fingers.

The bristles or pins 246 are here arranged in three rows, however, variations are possible as explained above. Depending on the nature of the formula constituting the product, the application member 250 shown can be replaced by a flocked applicator, a foam applicator, a flexible plastic spatula (typically thermoplastic-elastic) or the like.

The blade 264 is configured to cooperate with a slot provided in the gripping member 242, as explained above, although in this embodiment, the orientation of the applicator 240 relative to the body 210 is determined and invariant. As previously explained, the blade 264 could also be replaced by a contact between the inner bottom of the cover 260 and the gripping member 242.

Although the present description refers to specific embodiments, modifications can be made to these examples without departing from the general scope of the invention as defined by the claims. Further, individual characteristics of the different embodiments illustrated or mentioned may be combined in additional embodiments. Therefore, the description and the drawings should be taken in an illustrative rather than a restrictive sense.
