EP2362741B1 - Telescopic vial for a liquid or pasty cosmetic product - Google Patents

Description

The invention relates to a liquid or pasty cosmetic product bottle with an extensible configuration, comprising an applicator element provided with an applicator which is partly engaged telescopically, outside the periods of use for the application of the product, in a tubular reservoir containing the product to be applied; it applies, in particular but not exclusively, to mascara bottles or even to gloss bottles.

In conventional manner, such bottles, in particular mascara bottles, comprise a wiper provided near the neck of the bottle (in practice on the reservoir) which is intended to retain the excess of product taken by the applicator during each of its dipped in the tank, in the mass of product.

The applicator element includes in practice a cap on which the user acts to manipulate the mascara applicator. The fact that the mascara is liquid or pasty means that effective sealing must be performed outside the mascara application periods, when the cap is engaged on the neck of the bottle; this sealing is in practice obtained by a closure by screwing or clipping of the cap on the neck of the bottle. As a result, the cap is an element that forms a substantial part of the outer surface of a closed-set mascara bottle, and that combined movements or significant efforts may have to be made to open the bottle prior to an action. application of mascara.

The document EP - 1,721,543 describes various containers of cosmetic product, including a bottle of mascara (or even gloss in connection with Figures 18 to 24 ) comprising:

• a body elongate in a longitudinal direction and provided with a bottom and a free edge,
• a reservoir contained in this body and movable in translation between a low stable position and a high stable position, this reservoir comprising a neck,
• an elastically compressible device with two stable recoil positions disposed between the body and the reservoir and whose two stable axial recoil positions define the two low and high stable positions of the reservoir,
• an applicator element comprising a rod terminated by an applicator adapted to be loaded with mascara, said applicator element having a rest configuration in which a portion of the rod and the applicator are contained in the reservoir so as to enable the applicator to be loaded with mascara, and able to leave this resting configuration until it is completely out of the tank and the bottle,
• a cap integral with the rod of the applicator element and adapted to engage inside the body, the stable axial recoil configurations of the elastically compressible device being such that when the applicator element is in its configuration resting in the reservoir, either the cap is retracted into the body flush with the free edge of the body, or it is at least partly projecting out of this body,
• a wiper provided at the outlet of the reservoir so as to be traversed by the applicator during its penetration into the reservoir or during its extraction from it, and
• additional sealing elements carried respectively by the stem and the neck of the tank consisting of a protuberance carried by the rod and hooking claws provided on the neck of the tank (in the upper position of the tank, the claws move out the inner volume of the body in which the tank slides, while in the lower position, these claws are maintained in close configuration by the inner wall of the body so as to remain engaged on the protuberance).

Such a configuration is simple and reliable to use without significant risk of inadvertent opening, while allowing a very clean aesthetic, and without leading to a crippling obstruction.

Indeed, the retraction of the cap in the body of the bottle allows the aesthetics of the bottle is essentially defined by this body, while the presence of the elastically compressible device with two stable recoil positions allows a simple movement of depression the cap, transmitted to the reservoir, causes the passage of this device from a recoil position to another, and causes either the retraction of this cap (there is then very little risk that this cap is released unexpectedly out of the body), or the projecting portion of this cap which is sufficient to allow the seizure of this projecting portion between the fingers of a user and its extraction from the body to proceed to the application of the product taken by the applicator (which requires the user only simple movements, with one hand).

• une position basse dans le corps (permettant que le capuchon affleure le bord libre du corps), lorsque l'élément d'application est dans sa configuration de repos, c'est-à-dire que le dispositif élastiquement compressible est dans la plus rétractée de ses configurations stables, et
• une position haute dans laquelle son col est sensiblement au niveau de ce bord libre (pour permettre la séparation des éléments complémentaires d'étanchéité), définie par la plus allongée des configurations stables du dispositif élastiquement compressible.

It should be noted that, in such a bottle, the reservoir is movable between two main positions which are essentially defined by the elastically compressible device:

• a low position in the body (allowing the cap to be flush with the free edge of the body), when the applicator element is in its rest configuration, that is to say that the elastically compressible device is in the most retracted its stable configurations, and
• a high position in which its neck is substantially at this free edge (to allow separation of complementary sealing elements), defined by the most elongated stable configurations of the elastically compressible device.

The sealing elements remain in cooperation as long as the reservoir is located between these extreme positions, even when the cap has started to come out of the body.

Thus, such a bottle is not only simple and reliable in use but also has good sealing characteristics, without requiring complex movements on the part of the user, but at the cost of a certain complexity of structure .

It should be noted that, regardless of the aesthetic effect that the retraction of the applicator element allows in the body, the fact that this applicator element can telescopically engage the body also has the advantage to allow good ergonomics to be obtained by choosing the axial dimensions of the cap of the applicator element and the body (the larger these dimensions are, the easier it is for a user to manipulate this cap and this body) without these axial dimensions determine the bulk of the bottle in rest configuration (the axial size is even lower than the telescopic engagement of the application element in the body is important).

The subject of the invention is a bottle of liquid or pasty cosmetic product comprising a body, an applicator element telescopically engaged in this body and a reservoir adapted to contain this product and to receive a part of the application element. when in a rest configuration, having sealing properties at least similar to those of the aforementioned bottle, which is simple and reliable to use without requiring complex movement on the part of the user, while having a simpler structure does not require the presence of an elastically compressible device.

• un corps longiligne, s'étendant selon une direction longitudinale, muni d'une zone de fond et d'un bord libre,
• un réservoir contenant ce produit et mobile en translation dans le corps entre une position basse de repos proche de la zone de fond et une position haute de travail proche du bord libre, ce réservoir comportant un col,
• un élément d'application comportant une tige solidaire d'un capuchon et terminée par un applicateur adapté à se charger en produit lorsqu'il est plongé dans le réservoir en une configuration de recharge par rapport à ce réservoir dans laquelle la tige traverse le col de ce réservoir, ce capuchon étant adapté à s'engager dans/sur le corps en enfonçant cet élément d'application dans le réservoir jusqu'à la configuration de repos et adapté à être extrait de ce corps en sorte d'extraire la tige et l'applicateur hors du réservoir et du corps, et
• des moyens complémentaires d'étanchéité, prévus respectivement sur la tige de l'élément d'application et sur le réservoir à proximité de son col, conçus en sorte d'atteler en translation la tige et le réservoir en une configuration relative d'étanchéité, depuis la position basse jusqu'à proximité de la position haute du réservoir dans le corps et inversement,

caractérisé en ce que la position haute du réservoir dans le corps est définie par des éléments complémentaires de retenue prévus entre ce corps et ce réservoir et qui forment un point dur en sorte de générer une résistance à la descente du réservoir dans le corps à partir de cette position haute, la configuration du capuchon étant telle que, lorsqu'il est attelé au réservoir alors que celui-ci est en position basse de repos, il offre une prise suffisante pour permettre à une utilisatrice de lui appliquer une traction vers l'extérieur.To this end, the invention proposes a bottle for a liquid or pasty cosmetic product, comprising:

• an elongate body, extending in a longitudinal direction, provided with a bottom zone and a free edge,
• a reservoir containing this product and movable in translation in the body between a low rest position close to the bottom zone and a high working position close to the free edge, this reservoir comprising a neck,
• an applicator element comprising a rod integral with a cap and terminated by an applicator adapted to be loaded with product when it is immersed in the reservoir in a refilling configuration with respect to this reservoir in which the rod passes through the collar; this reservoir, this cap being adapted to engage in / on the body by pressing this applicator element into the reservoir to the rest configuration and adapted to be extracted from this body so as to extract the rod and the applicator out of the tank and the body, and
• complementary sealing means, respectively provided on the rod of the applicator element and on the reservoir near its neck, designed so as to couple in translation the rod and the reservoir in a relative sealing configuration, from the low position to near the high position of the tank in the body and vice versa,

characterized in that the high position of the reservoir in the body is defined by complementary retaining elements provided between this body and this reservoir and which form a hard point so as to generate resistance to the descent of the reservoir into the body from this high position, the configuration of the cap being such that, when it is coupled to the tank while it is in the low rest position, it offers a sufficient grip to allow a user to apply a pull to the outside .

The complementary retaining elements are advantageously provided on the inner wall of the body and on the outer wall of the tank, respectively.

It will be appreciated that a bottle according to the invention has most of the advantages of a bottle such as that described in the document EP - 1,721,543 without requiring the presence of any compressible device, taking advantage of the fact that the presence of additional sealing elements between the application element and the reservoir ensures in practice an axial coupling which ensures that, as soon as the cap of this application element offers, in the rest configuration of the bottle, a sufficient grip for a user to apply a pull to the outside of the body, this extraction involves a simultaneous rise of the reservoir from its lower position in the body to 'to its high working position. The additional restraint elements of the reservoir in the upper position in the body then allow the maintenance of this reservoir in its working position after the user dissociated the complementary sealing elements; it suffices to size them taking into account the mechanical stresses to which this reservoir is likely to be subjected in high working configuration (in particular, the crossing by the applicator of the wiper that includes the reservoir, in case of mascara, and gravity).

Advantageously, the complementary retaining elements are designed so as not to hinder the arrival of the tank in the up position at the end of the climb from the low position, which confers on these complementary retaining elements a selective effect according to the direction tank displacement; they tend to resist the descent of the tank, but do not oppose resistance when the user brings the tank in this high position, and do not involve unnecessary effort on the part of this user when bringing the tank bottle in its service configuration.

Of course, the complementary retaining elements may, in a simplified configuration simply consist of a combination of a circumferential rib, continuous or discontinuous, formed on the body or the reservoir, and a circumferential groove, continuous or discontinuous, arranged on the other of these parts so as to obtain a clipping effect.

However, advantageously, the complementary retaining elements comprise, on the one hand, a hollow guide track substantially disposed in the longitudinal direction of the body and, on the other hand, a follower pin adapted to circulate in this hollow guiding track. during movements of the tank between its low and high positions in the body, an elastic element being attached to this hollow track to resiliently resist the passage of the follower finger at the beginning of a displacement of the tank from its upper position. work towards its low rest position. The advantage of such a combination of a guide track and a follower pin is in particular to ensure good control of the trajectory of the reservoir inside the body; as for the presence of an elastic element, it has the advantage of ensuring the retention elastically, without risk of degradation while the fact that this part is reported makes it possible to adjust the resistance offered by these complementary elements of restraint according to the various stresses against which this restraint must be ensured (in particular with regard to the stresses applied to the reservoir during each crossing of the wiper in the case of a bottle of mascara).

Preferably, this elastic element is designed and arranged so as to deform parallel to the walls of the reservoir and the body but transversely to the longitudinal direction of the body. Such an arrangement allows, in particular, that this elastic element deforms with a magnitude that is independent of the thickness of the clearance between these walls of the reservoir and the body.

According to an advantageous example of embodiment, the elastic element reported being disposed along a side of this hollow guiding track at its end defining with the follower pin the upper working position of the reservoir, so that this blade impinges in the path of the follower finger and can be crossed by the follower finger only by elastic flexion. Such a configuration is particularly simple.

Preferably, this end of the guide track defining with the follower pin the high working position of the reservoir is a portion having the shape of a drop and whose bottom is provided with non-return steps imposing a single direction of circulation follower finger in this drop, the reported elastic element being located near a zone of this portion in which the follower finger flows at the beginning of a movement of the reservoir from its upper working position to its lower guide position. This makes it possible to obtain the aforementioned selective effect of the complementary retaining elements.

According to another advantageous example of embodiment, the hollow guide track comprises, in the bottom of its end defining with the follower pin the upper working position of the reservoir, a cavity having a ramp parallel to the longitudinal direction connecting to the bottom of the rest of the track, the follower finger is resiliently biased toward the bottom of this track and the elastic element attached is a U-shaped part engaged in the cavity so that its branches are oriented longitudinally, these branches being configured so as to form between them a space that can receive the follower finger while defining, opposite the bottom of the U with respect to this space, a constriction that can not be crossed by the follower finger from this space to the outside of the U-shaped piece, that by a spacing of these branches forced by the follower pin, these branches being further configured and arranged so that when the tank approaches its position high work, the follower finger slides on the bottom of the track then on the branches until snapping into space. Such a configuration has the advantage of obtaining the aforementioned selective effect about the complementary retaining elements, by the simple combination of a cavity and a U-shaped part, in a hollow track that can be simply straight.

According to yet another advantageous example of embodiment, the hollow guiding track has a cavity in the bottom of its end defining with the follower finger the high working position of the reservoir, the follower finger is resiliently biased towards the bottom of this track and the reported elastic member is an insert engaged in the cavity so as to allow sliding of the follower finger on this piece until a snap of the follower finger in the hollow when the reservoir approaches its upper working position, the follower finger being elastically biased towards the bottom of this cavity so as to escape by ramp effect out of this hollow. In other words, the escapement of the follower pin outside the space in which it snaps into the high position of the reservoir is obtained by a suitable configuration of the follower or support finger.

Thus, according to a first advantageous example, the follower finger is carried by an elastically flexible blade and has a flank forming a ramp allowing the follower finger out of this hollow. According to another advantageous example, the follower pin is connected to a support by a flexible connection zone, whereby this follower finger can tilt longitudinally to escape out of the hollow of the insert.

The configuration of the hollow track at its end defining, together with the follower pin, the low rest position of the tank may be a simple dead end.

However, it may be interesting to configure this track and its follower finger so as to ensure for the user a feeling that this low rest position has been achieved, for example by a latching effect. For this purpose, the hollow track advantageously comprises, at its end defining with the follower finger the low position of the reservoir, a portion at the bottom of the bag having a constriction generating resistance to the passage of the follower finger.

It may also be desired to ensure that the reservoir is lowered into the body until it reaches its low position. For this purpose, the hollow track advantageously comprises, at its end defining with the follower finger the lower position of the reservoir, a drop-shaped portion provided with non-return steps defining a single direction of circulation of the follower finger in this portion. Consequently, as soon as the tank has descended to a position where the follower finger has crossed only one of the non-return steps (in practice made in the bottom of the track), the tank will not be able to go back up as long as it will not have reached the lowest position first. In addition, this configuration also provides an effect indicating to the user if it has cleared the tank out of its low rest position; for this purpose, an elastic element is advantageously disposed near this drop-shaped portion so as to generate a resistance against the passage of the follower finger in the direction of a rise of the reservoir in the body.

Various couplings can be envisaged between the application element and the reservoir.

According to an advantageous configuration, these complementary sealing elements comprise, on the rod on the one hand, a protuberance comprising, in the direction of the applicator, a sealing portion and, in the direction of the cap, a transverse bearing, and, on the reservoir, on the other hand, below its neck, a narrowing adapted to receive in axial abutment the sealing portion and, beyond its neck, a collar formed, the along its circumference, a plurality of rigid sectors and alternating elastic sectors, this collar having a relaxed configuration in which it has a bulk greater than the internal section of the body and a restricted configuration in which it is confined inside of this body, the rigid sectors comprising, along the inner edge of this flange, flanges adapted to come into axial abutment against the transverse bearing surface of the protuberance so as to maintain the sealing portion against shrinkage when the element d application is in its rest configuration.

Such a construction has similarities with the configuration proposed by the document EP - 1,721,543 (Also usable in the context of the present invention) which comprises claws coming to apply an axial force on the protrusion as they come closer.

But we understand that the existence of these claws, which participate in the definition of the opening that the rod and its applicator must cross during the penetration into the tank or extraction out of it, leaves gaps may become dirty by the product carried by the applicator, which can affect the sharpness of the neck of this tank, as well as the durability of the applicator (if it may be degraded during crossing) of these claws). In addition, the axial force that is applied to the rod due to the ball shape of the protrusion may vary with time or with the wear of these claws, so that the sealing effect is also likely to vary with time. On the other hand, thanks to the fact that the sealing is ensured thanks to the implementation, not of claws, but of a collar formed of a plurality of rigid sectors and of elastic sectors, the formation of interstices is avoided in which the product may enter at the risk of hindering the posterior use of the bottle. Moreover, the fact that this flange acts on a transverse surface that includes the protuberance, the retraction of this flange does not necessarily imply an axial force, which allows that the seal is provided regardless of the instantaneous configuration of the flange, since it began to retract from its relaxed configuration.

Advantageously, the sealing portion of the protuberance comprises an elastic portion or a seal, for example reported.

According to another advantageous configuration, simpler, therefore more economical and more robust, the complementary sealing means comprise, on the rod on the one hand, a protuberance comprising, in the direction of the applicator, a sealing portion and, in the direction of the cap, a transverse surface, and on the reservoir on the other hand, a seat-shaped narrowing adapted to receive in axial abutment the sealing portion and at least one boss formed on the inner wall of the reservoir between its neck and this narrowing and adapted to be crossed by the protuberance when the applicator element is engaged in charging configuration in the reservoir, and to maintain this protrusion against its seat as the application element remains in charging configuration.

The bottle of the figure 1 , represented by the general reference 1, mainly comprises:

• an elongated body 10 extending in a longitudinal direction, here vertical, and provided with a bottom zone 11 and a free edge 12,
• a reservoir 20 containing mascara having a bottom 21 and a neck 22, and adapted to be entirely contained in the body being movable in translation between a low rest position (close to the bottom zone of the body) and a high position working (closer to the free edge); this reservoir here comprises a flange 23 facilitating guiding and maintaining the reservoir in the body,
• an applicator element 30 comprising a rod 31 secured to a cap 40 and terminated by an applicator 32 adapted to be loaded with product when it is immersed in the reservoir in a refilling configuration with respect to this reservoir in which the rod passes through the neck 22 of this reservoir, this cap 40 being adapted to engage in, or on, the body by pressing this applicator element into the reservoir to the rest configuration and adapted to be extracted from this body by sort of extracting the rod and the applicator from the reservoir and the body, and
• complementary sealing means 35 and 80 respectively provided on the rod of the applicator element and on the reservoir near its neck, designed to couple in translation the rod and the reservoir in a relative sealing configuration, from the low position to near the high position of the tank in the body and vice versa.

• une pièce formant essoreur 70, adaptée à s'engager dans la partie haute du réservoir au travers de son col, et
• une pièce d'étanchéité 80, adaptée à s'engager sur l'extrémité du réservoir en sorte de coiffer la pièce formant essoreur, et adaptée à coopérer avec une protubérance 35 portée par la tige de l'élément d'application.

In the example of the figure 1 two pieces are intended to be mounted at the neck of the tank 20:

• a wiper part 70, adapted to engage in the upper part of the reservoir through its neck, and
• a sealing member 80, adapted to engage the end of the reservoir so as to cap the wiper member, and adapted to cooperate with a protrusion 35 carried by the rod of the applicator element.

These parts are differentiated here, which makes it possible to clearly identify the functions performed near the neck of the tank, but it should be understood that these functions can, alternatively, be provided by one and the same piece. These parts are in practice integral with the tank and therefore form an integral part.

As will be detailed below, the cooperation of the sealing member 80, integral with the reservoir, and the protrusion 35 of the rod establishes a coupling between the reservoir and the application element.

The body may be formed of one or more parts integral with each other; in the example here considered this body comprises a tube of any section (circular, rectangular, polygonal or other), open at both ends; a possible insert forming a cage, not shown on this figure 1 , is advantageously provided to materialize the bottom of the body; such a bottom, when it exists, may alternatively be made in one piece with the tubular part, for example by molding.

The high position of the reservoir in the body is defined by complementary retention elements, provided on the inner wall of this body and on the outer wall of this reservoir, which are designed so as to generate resistance to the descent of the reservoir into the reservoir. body from this position high, preferably without hindering the coming up position at the end of rise from the low position.

In addition, the configuration of the cap is such that, when it is coupled to the tank while the latter is in the low rest position, it offers a sufficient grip to allow a user the application of an extraction effort out of the body; in practice, such a sufficient grip is obtained when the cap projects out of the body over a few millimeters, typically 5 millimeters, or even a little less (for example 3 millimeters); of course this minimum projecting distance depends on the surface condition of the portion of the cap which is protruding (the rougher this surface state, the more this distance can be small).

In general, the complementary restraint elements are schematized under the common reference 60 to the figure 1 .

In the examples described below, these complementary retaining elements comprise, on the one hand, a hollow guide track substantially disposed in the longitudinal direction of the body and, on the other hand, a follower pin adapted to circulate in this hollow track. during movement of the reservoir between its low and high positions in the body, an elastic element being attached to this hollow track to resiliently resist the passage of the follower finger at the beginning of a displacement of the reservoir of its position high working towards its low rest position.

The Figures 2 to 6 correspond to a first embodiment of a bottle according to the invention. The reference signs which relate to elements similar to those of the figure 1 are identical to those in this figure 1 , being assigned a "premium" index.

The structure of the additional restraining elements is apparent figures 2 and 3 .

The hollow guide track, denoted 62 ', is here carried by the body, more precisely by the insert forming cage 10B' while the follower pin, denoted 63 ', is carried by the reservoir. However, it is understood that the situations can be reversed, not shown variant.

This hollow guiding track 62 'has two end portions 62A' and 62B ', one of which, in the example described, is shaped so as to be in the form of a drop. Together with the follower pin, this portion 62B 'defines the high position of the reservoir.

The follower pin 63 'is preferably mounted at the end of an arm 63'A, generally oriented parallel to the longitudinal direction of the bottle, and the other end 63'B is articulated on the portion which carries the follower finger .

In the example considered here where the follower pin is carried by the tank, the end 63'B of the arm is bent so as to be articulated under the bottom of the tank.

The detail of the hollow guiding track 62 'appears clearly at the figure 3 .

It is understood that when the follower pin is in the lower portion 62'A, the reservoir is in its low rest position and is in principle not subject to any effort; the tank remains in this position as a user does not need to access the contents in this tank.

The other extreme portion, 62'B, is advantageously provided with non-return steps 200 guaranteeing that the finger, at the end of extraction of the reservoir to its upper position, necessarily follows a single branch of the drop form, here that of left, and necessarily reaches its extreme position B before being able to descend towards the portion 62'A.

It may be noted that the guide track has a common intermediate portion 62'C for raising the follower finger from the low position A to the high position B and the descent from B to A; alternatively not shown, there are two separate longitudinal tracks, one for the climb, the other for the descent.

Additional guiding elements are advantageously provided to ensure good control of the movement of the reservoir in the body; these elements are here schematized by a longitudinal groove 24 ', here formed on the outer wall of the reservoir, cooperating with a longitudinal rib 25', here formed in the cage 10B '.

As indicated above, additional retaining elements are provided to generate a resistance to the descent of the reservoir in the body from this high position, preferably without hindering the coming up position at the end of climb from the position low.

For this purpose, an elastic element 65 'is provided near the extreme high portion of the track, along a side thereof, so as to encroach on the path of the follower finger, when it tends to leave corner area B; therefore, a passage of the finger is possible only on the condition of applying to the cap a driving force sufficient to force a deformation of the elastic element until it can be crossed by the finger. It will be appreciated that, thanks to the drop-shaped conformation of the portion 62'B, this elastic element constitutes an obstacle that the finger must cross during the descent, but not during its ascent.

It may be noted that this elastic element is here a blade, preferably metal, which is reported, which allows to better adjust, depending on the constraints that the tank is likely to have to undergo in its upper working position, the importance of the hard point that this piece constitutes, by a suitable choice of the elastic piece that is put in place (from the point of view of material or geometry, in particular); in practice it should be ensured that, in the case of a bottle of mascara, this hard point is sufficient to hold the reservoir in place when a user plunges the applicator into the reservoir against the resistance generated by the wiper; of course, this hard point is also made so that it can withstand the simple weight of the tank.

It may be noted that such an elastic element 65 'is arranged so as to be deformable, locally, parallel to the walls of the reservoir and the body but transversely to the direction of translation of the reservoir in this body. In other words, the deformation of this elastic element can be chosen independently of the thickness of the clearance existing between these walls, which allows to freely choose the stiffness of this spring, its shape, its nature, etc.

We can note, on the figure 2 , that the retaining device constituted by these complementary retaining elements is located between the side walls of the reservoir and the body; this allows that, in the rest position, the tank can be very close to the bottom of the body, hence an optimal use of the volume of the latter.

It has been indicated that part of this device is mounted on the cage insert 10B '. An interest that the body has such an insert is that the establishment of this device between the insert and the reservoir can be done outside the tube 10A and the engagement in the body of the assembly 10B '+ 20 ', then guarantees the retention in place of the complementary elements in cooperation configuration.

For this purpose, the insert 10B 'advantageously has the shape of a sleeve having (see in particular the figure 2 ) a longitudinal slot 14 'opposite the inner zone of this sleeve where is formed the hollow guiding track; this sheath 10B 'therefore has a C-shaped section. Thus, when the elbow 63'B of the arm 63'A has been positioned in a suitable recess in the bottom of the reservoir, the transversal engagement of the reservoir through the slot , by accentuating the opening of the shape of the C, allows the positioning of the follower pin in any area of the hollow guiding track; it then suffices to axially engage the assembly in the tube to ensure the maintenance of the arrangement thus obtained.

Alternatively, the longitudinal slot 14 'may have a width identical to the width of the inner volume of this sleeve, which allows easy engagement of the reservoir in this sleeve.

Side lights 15 'may be provided in the residual wall of the sheath 10B', at a distance from the slot 14 '. Such lights allow lightening of the sheath while providing access to the inside of the sheath.

When using the bottle, when the user wants to apply mascara, she grasps the protruding portion of the cap and causes the rise to bring the reservoir into its upper working position B and remains there because of the presence of the elastic element.

It is interesting to note that removing the cap from the body causes the tank to rise as a result of the presence of elements. complementary sealing ensuring a coupling between the cap and the reservoir, via the rod which this cap is secured.

The figure 4 represents the piece 80 'assembled on the neck of the tank 20', while the figures 5 and 6 represent this piece 80 'together with the wiper piece 70'.

This wiper member 70 'is conventionally designed to control the amount of product that comes out with the applicator when the user pulls the applicator element out of the reservoir. This is typically a piece of flexible material capable of wringing, in a controlled manner, the applicator; this piece has in practice a shape defined according to the shape of the applicator. This wiper member comprises a narrowing 71 'forming a sealing surface, constituting a seat adapted to cooperate with the lower part of the protuberance 35' that comprises the rod of the applicator element; under this narrowing is located a squeezing lip 72 'of any known type suitable. It should be noted, however, that since the operation of the applicator element with respect to the reservoir does not need to include a rotation component, the shape of the applicator element, and therefore of the wiper, can be chosen freely, without necessarily being symmetrical with respect to a longitudinal axis.

More specifically, the protrusion 35 'comprises a sealing portion 35'A, optionally provided with a seal, adapted to be applied axially against the sealing surface 71'. Advantageously, the sealing surface is completed by a portion forming a plug 35'B adapted to engage in the wiper part 70, beyond the narrowing; this results in a complementary sealing effect.

The protuberance 35 'here has a generally frustoconical shape flaring towards the cap and comprises, at a distance from the sealing portion 35'A towards the cap, a transverse bearing 35'D.

The additional sealing piece 80 'comprises a flange formed, along its circumference, with a plurality of rigid sectors 81' and of flexible sectors 82 ', by virtue of which it admits a relaxed configuration in which it has a transverse bulk. superior to the internal section of the body and a restricted configuration in which, by compression of soft areas, it is confined in the internal volume of the body. In the example shown, there are rigid sectors alternating with flexible sectors.

At least the rigid sectors 81 'comprise, along the inner edge of the flange, flanges 81'B adapted to engage axially against the transverse extent of the protuberance 35'. Advantageously, flanges 82'B are also provided on the flexible sectors. In addition, these sectors advantageously comprise external flanges 81'C or 82'C, cooperating with the free edge of the body to force the passage of the flange of its relaxed configuration to its restricted configuration when the reservoir descends into the body.

In fact, the piece 80 'comprises a skirt 84' whose axial dimension makes it possible to fix the axial distance between the flanges 81'B and the constriction 71 'so that the engagement of the flanges 81'B against the span transverse of the protuberance 35 'is obtained when the sealing portion 35'A is applied against the sealing surface 71'; the engagement of the flanges against this transverse surface thus ensures the maintenance in position of these sealing elements.

Advantageously, the skirt 84 'is rigid and forms, with the rigid sectors, a single piece, while the flexible sectors are formed by overmoulding of this single piece.

It will be understood that the cooperation between flanges 81'B and span 35'D ensures an axial coupling between the reservoir and the application element as long as the flange (and the skirt) are kept in their restricted configurations, which allows that an extraction movement applied by a user on the cap, thus on the applicator element is transferred to the reservoir, which ensures that the follower finger is indeed brought to its position B.

The figure 5 represents a configuration where a user has partially engaged the applicator element in the reservoir, i.e. the rod 31 'has already passed through the parts 70' and 80 ', and the protuberance is about to engage in room 80 '. The collar is in its relaxed configuration.

When crossing the parts 70 'and 80', the applicator 32 does not drive the reservoir 20; this reservoir 20 is in fact retained relative to the body 10 by the element 65 'which has a greater resistance than that generated by the parts 70' and 80 '.

Continued driving movement brings the sealing portion of the protuberance against the sealing surface 71 'while the skirt of the workpiece 80' engages the body, which has the effect of starting the effect. containment of the collar; the inner flanges 81'B are axially at the rear transverse scope of the protuberance. The skirt has a ramping effect, amplified by the presence of external flanges 81'C, or 82'C, to cause, with the free edge of the body, the deformation of the flange into its restricted configuration. The penetration of the flange into the body causes the approximation of the flanges 81'B and therefore the engagement thereof against the transverse range 35'D: the flange is therefore in its restricted configuration.

This movement continues until the reservoir reaches its maximum sink configuration, corresponding here to a partial retraction of the cap in the body, about half of its height ( figure 6 ). As a variant not shown, this portion of the cap which remains projecting may be larger or on the contrary lower, depending on the needs as well as the surface condition of the cap.

The figure 7 represents another embodiment of a bottle according to the invention, which has with respect to that which has just been described two differences which are in practice independent of one another.

The elements of this other bottle which are similar to those of Figures 2 to 6 are indicated by signs which are deduced from those used on these Figures 2 to 6 by replacing the "prime" index with the "second" index.

One of the differences is the way in which the seal, and thus the coupling, is achieved.

It is thus observed that in this example of the figure 7 , the collar has been replaced by bosses 81 "B formed on the inner wall of the tank above the seat portion for the sealing surface 35 "A. Moreover, the protrusion here has a shape not frustoconical but more rounded, the bosses cooperating on the portion of this protrusion which has the maximum section.

In fact, the implementation of such bosses, provided they are sufficiently sized, has appeared to provide a seal and sufficient coupling for a bottle of mascara, especially when the protrusion comprises the portion 35 "B forming a cap.

Another difference lies in the fact that, in the example of this figure 7 , the cap 40 "has an outer skirt 40" A which runs along the outside of the body during its telescopic engagement in the body.

The Figures 8 to 16 represent another example of a retaining device capable of delimiting the high position of the reservoir in the body. The elements similar to those of the preceding figures are designated by figures which are deduced from those used in these previous figures by the addition of the number 100 and the suppression of the indices.

The figure 8 represents a piece 110B adapted to be inserted longitudinally into the body, similarly to the piece 10B 'of the figures 2 and 3 . This piece is elongated and is adapted to be secured to this body by any appropriate means, for example by gluing.

This elongate piece 110B comprises a longitudinal guide track 162 adapted to cooperate with a follower pin formed of a lug 163 intended to be coupled longitudinally to the outer wall of the tank. This lug is here an integral part of a resilient curved piece, advantageously metallic, provided with elastic arms 163A; indeed, this lug is intended to be biased elastically towards the part 110B. This track has a blind end A and, at a distance from this blind end, a cavity 162B adapted to receive a U-shaped piece 165, forming a retaining clip, having its concavity turned towards the blind end. Between the branches 165A and 165B of this U-shaped piece, the cavity comprises a longitudinal ramp 162C going from the level of the bottom of the cavity to the level of the bottom of the track. In their rest configuration, the arms of the U-shaped part are, by their flanks, in the extension of the track. This U-shaped piece is shaped, near the junction of the arms with the base of this U, so as to define together with the bottom of the cavity, a housing B adapted to receive the lug 163.

The U-shaped piece has, at the outlet of this housing, a throat 165C formed jointly by enlargements of the arms. This constriction has a width less than the width of the lug 163.

Beyond this constriction, the arms have facing edges which gradually move apart from each other, on either side of the ramp, while having a spacing which remains smaller than the width of the rail. ergot.

Advantageously, the track 162 comprises, near the blind end A a protrusion 162D, here lateral (it is more precisely a pair of two projections), defining a local restriction of the track.

The retaining clip is advantageously secured to the part 110B, for example by means of a transverse pin, or by partial bonding, leaving the arms free to move inside the cavity.

The engagement of the reservoir in the body is easily done, after coupling the pin 163 to this reservoir, by sliding thereof in the portion of the track which is beyond the cavity 162B (see figure 11 ).

The high position of the tank is defined by the cooperation of the elements 110B and 163 in a configuration in which the lug 163 is in the housing B ( figure 12 ), while the low position is defined by these same elements in a configuration where the lug 163 is in the blind end A ( figure 13 ).

The figure 14 is a sectional view showing the cooperation of the various elements represented in Figures 8 to 10 . It can thus be noted that the lug 163 is engaged in a cavity 120E of small dimensions of the outer wall of the tank 120, pushed by its arms towards the bottom of the cavity 162B. The longitudinal dimension of the cavity 120E is just sufficient for the arms of the elastic support of the lug can come to be housed between its edges while being able to deform so as to allow the lug to retract at least part inside this cavity 120E, when this lug is facing the track.

In this second embodiment, the reservoir and the application element comprise complementary sealing and coupling elements similar to those of the Figures 2 to 7 , capable of ensuring, when they cooperate, a coupling of this reservoir and this application element.

When the reservoir is in its high position in the body, the lug is engaged in the housing B, between the arms of the retaining clip 165. This lug is held in this position by the fact that the throat 165C formed on the arms does not allow the release of this lug without spacing arms by elastic deformation, bending, these arms. It is therefore necessary to apply a significant effort to force the arms to deviate (see figure 15 ). When the arms are sufficiently apart, the lug slides by its front portion on the ramp, which forces the arms 163A to deform to allow a retraction of the lug in the cavity 120E, which also helps to resist any inadvertent movement of descent of the tank into the body. While the lug retracts into the tank cavity out of that of the part 10B ", it emerges from the arms of the retaining clip and its end comes to the level of the bottom of the track; the lug can then follow the track 162 towards the low point, to cross the throttle 162D (if it exists) and reach the low position defined by the zone A of the figure 13 .

When a user wishes to apply the product, it pulls on the cap, so on the application element, and therefore on the tank to which this element is coupled. This results in an effort tending to raise the lug along the track. The force applied must overcome the hard point constituted by the constriction formed by the protrusions 162D.

When the lug reaches the cavity 162B, the fact that the flanks of the arms of the retaining clip are, in their rest configuration, in the continuation of the track, has the consequence that the lug slides on these flanks without coming between these arms ( figure 16 ); it follows that this retaining clip offers no resistance to the movement of this lug until it snaps into housing B. The tank is in its upper position, as in the figure 12 .

The Figures 17 and 18 represent an alternative embodiment of the complementary retaining elements of the aforementioned bottle. In these figures, elements similar to those of Figures 8 to 16 are designated by signs that are deduced from those used in these figures by adding the number 100.

This is how this figure 17 represents a part 210B, corresponding to the sheath 10B 'of the figure 3 , on the inner wall of which is formed the longitudinal track 262 with a low extreme portion similar to that of the figure 3 , and an extreme high portion similar to that of Figures 10 to 16 .

The cavity 262B in which is engaged the U-shaped piece 265 is here formed in the thickness of the wall of this piece 210B and no longer transversely to this thickness from the inner surface; this facilitates the establishment of this piece 265, while avoiding that this part can escape outside the cavity during the movements of the follower finger.

This follower finger 263 is here analogous to the follower finger of Figures 2 to 7 , being carried by an arm 263A connected to a hinge portion 263B at the bottom of the tank.

The cooperation between this piece 265 and follower finger 263 is shown in FIG. figure 18 ; it is analogous to that described for Figures 8 to 16 , the arm 263A having an elastic flexibility sufficient to urge the finger towards the bottom of the cavity, while allowing a recoil thereof when the follower pin is out of the cavity, by spreading the branches of the part 265, as in the figure 15 .

The figure 19 is a variant of the figure 17 in which the analogous elements are designated by reference signs which are deduced from those of this figure by the addition of the number 100.

This variant differs from the embodiment of the figure 17 in that the U-shaped piece 365 comprises a bridge between its branches so as to completely close the contour of the space in which the follower pin snaps into the high position of the reservoir; in this way, this U-shaped piece is plus a piece elastic, in the sense indicated above, since the branches of this room can not deviate.

The escape of the follower finger from the hollow formed in this insert 365 can then be ensured by inclination of the follower pin parallel to the track as shown in FIG. figure 20 for example by bending a connection zone of this finger to the arm 363A which carries it.

Alternatively, this follower pin 363 can be replaced by a lug 463, carried by a curved elastic blade having resilient arms 465 as shown in FIG. figure 8 but having an inclined flank 464 adapted to allow, by a ramping effect all the more marked that this flank is inclined significantly towards the longitudinal axis of the bottle, the escape of the follower finger from the hollow of the piece 365 during a sufficient effort applied to the cap to make it go down along the body.

It is understood that in the examples of Figures 19 to 21 the ramp provided in the cavity containing the insert may be omitted; however, when present, it may have the advantage of facilitating the good guidance of the end of the follower pin to the bottom of the track outside the cavity.

We understand that figures 18 and 20 , the representation of the dashed follower finger corresponds to a configuration where the follower finger is flowing along the hollow track.
