Definitions

  • the invention relates to a liquid or pasty cosmetic product bottle, comprising a retractable applicator element, provided with an applicator which is engaged, outside the periods of application of the product, in a tubular container containing the product to be applied; it is particularly applicable to mascara or gloss bottles, that is to say fluid products, ie liquid or viscous.
  • bottles for a liquid or viscous cosmetic product have an application element.
  • This application element comprises in practice a cap that the user grasps with the fingers of one hand to apply the product on her eyelashes or lips, for example.
  • the fact that the product is fluid means that effective sealing must be performed outside the periods of product application, 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.
  • the cap is an element that forms a substantial portion of the outer surface of a mascara or gloss bottle in a closed configuration, and that combined movements or significant efforts may be required to open the front vial. a product application action.
  • Such a configuration is simple and reliable to use without significant risk of inadvertent opening, while allowing a very refined aesthetic (the mobile part retracts completely in rest configuration, telescopically), and without leading to a crippling obstruction .
  • the tank is movable between two main positions which are essentially defined by the device elastically compressible, the complementary sealing elements remaining in engagement with each other as the tank has not reached its upper position and must come axially outside the body to be able to separate.
  • the stroke of the elastically compressible device must be at least equal to the axial dimension of the cap.
  • 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 and dimensional constraints.
  • the rod comprises a protuberance comprising, in the direction of the applicator, a sealing portion and, in the direction of the cap, a transverse bearing
  • the reservoir comprises, below at its neck, a narrowing adapted to receive in axial abutment the sealing portion and, beyond its neck, a collar formed along its circumference, a plurality of rigid sectors and elastic sectors, this collar having a relaxed configuration in which it has a transverse bulk greater than the internal section of the body and a restricted configuration in which it is confined inside this body, the rigid sectors comprising, along the inner edge of this collar, flanges adapted to come into axial abutment against the transverse extent of the protuberance so as to maintain the sealing portion against shrinkage when the application element is in its rest configuration; preferably, at least the rigid sectors of the flange further comprise external flanges bearing against the inner wall of the body for maintaining the flange in its restricted configuration inside the body; advantageously, the flange is connected by a skirt
  • this document proposes that, as soon as the elastically compressible device brings the cap into a configuration where it provides a sufficient grip so that the fingers of a user can apply a pull, it is no longer required that this device elastically compressible is able to remount the tank to its upper working position, a tensile force on the cap to complete the upward movement of the tank to this high position, in which the tank can then be maintained by the presence of a hard point braking the descent from this high position.
  • the collar like the claws of the previous document, can not deviate radially and release the protuberance when the tank is sufficiently raised in the body for this collar (or these claws) is outside this body; in other words, the release of the protuberance is fixed by crossing the edge of the body in which retracts the application element.
  • the seal results from the existence of an axial component resulting from the effect of the flange on the protuberance, which amounts to saying that the axial coupling function between the applicator element and the reservoir and the sealing function are coupled.
  • the unlocking of the axial coupling between the applicator element and the reservoir can be done at any point chosen by the designer of the bottle inside the body, without it is necessary that the tank, or that the peripheral or internal parts, leave this body; this helps to maintain the aesthetics of the bottle including use configuration.
  • the frictional engagement of the portion widened rod in the upper part of the inner skirt ensures a satisfactory seal independently of locking in an axial direction provided by the movable finger.
  • the cam surface is located to cooperate with the head of the finger on the end of the tank stroke towards its maximum driving position. That is to say that the locking of the applicator element on the reservoir takes place only on a small part of the displacement of the reservoir; it can be noted that, if the raising of the tank to its upper working position (minimum driving position) is provided by the elastically compressible device, a traction of the application element by the fingers of a user In practice, this occurs only at times when this applicator element can be separated from the reservoir without the need to maintain the seal with the reservoir; the friction engagement of the enlarged portion in the upper part of the inner skirt does not need to be done with much force.
  • the cam surface is located so as to cooperate with the head of the finger over a longitudinal distance at most equal to one third of the displacement of the reservoir inside the body from the low rest configuration.
  • the flared surface of the upper part of the inner skirt of the inner part is connected to a relief, advantageously annular, intended to cooperate with the widened portion of the rod, in which is advantageously formed a hollow, possibly annular, intended to receive this relief.
  • the flared surface of this inner skirt is connected to a hollow, advantageously annular, intended to cooperate with the widened portion of the rod, which is advantageously provided with a preferably annular relief.
  • the inner skirt further comprises a lower part - the inner skirt thus forming a double skirt - and the lower part converges towards the bottom of the tank and towards the longitudinal direction.
  • the lower part is for example more flexible than the upper part.
  • the rod comprises a narrowed zone located longitudinally at a level such that, when the applicator element is in its closed configuration in the reservoir, a free edge of the lower part of the inner skirt of the inner part is located around this narrowed area.
  • the lower part of the inner skirt of the inner part extends, in the longitudinal direction, over a distance at most equal to half the distance over which the upper part of this inner skirt extends. .
  • the lower part of the inner skirt of the inner part has a thickness which decreases towards the bottom of the tank. This allows to give a great flexibility to this lower part near its free edge, which facilitates its role of spin lip.
  • the widened portion of the rod of the applicator element comprises a convergent portion extending from an upper edge of a flared surface of this enlarged portion towards the stem, for example towards a vertex of the rod, so as to force a spacing of the finger vis-à-vis the rod during a longitudinal movement of the applicator element out of the tank. This helps to ensure that the finger is moved away from the rod when the head is no longer applied against the cam surface.
  • the peripheral piece and the inner piece are made of moldable plastic materials. This allows a great simplicity of manufacture.
  • peripheral part and the inner part may be shaped in one piece or in two separate parts which would then, for example, resiliently nested one into the other.
  • the body comprises an outer part and an inner part in which is formed the cam surface. This allows to choose for the outer part a material providing the desired aesthetic and for the inner part a different material compatible with the desired geometry.
  • the internal surface of the body and the external surface of the reservoir comprise complementary elements constituting a hard point inducing a resistance to movements of the reservoir in the body from its high working position, in particular for example to the descent of the tank into the body from its upper working position.
  • the Figures 1 to 3 represent a bottle rated 1 as a whole. It comprises mainly a body 10, a tubular reservoir 20 movable inside the body 10, an elastically compressible assembly 30 interposed between the body and the reservoir, an application element 40 adapted to cooperate with the reservoir 20 and a cap 50 which carries the application element 40 and which is adapted to close the body 10 when the application element 40 is engaged in the reservoir 20.
  • the body 10 is elongate, elongate in a longitudinal direction ZZ, here vertical, provided with a bottom zone 11 and a free edge 12.
  • the longitudinal direction here is an axis of symmetry, the section of the body having, in the example, a square shape (see Figures 5 and 6 ), or more precisely a form of curved square, that is to say that the lateral faces of the body are bulged outwardly.
  • the section may have a rectangle shape, or a simpler geometrical shape, for example that of a circle (symmetry of revolution), or even a more complex shape, for example polygonal with a greater number of angles. four, or oval, etc.
  • this longitudinal direction is such that, in any plane passing through it, it is an axis of symmetry for the intersection of the body and this plane.
  • the body 10 may be formed in one piece, or be formed of several pieces attached to each other (for example a tube which is reported a bottom piece).
  • this body is formed of an outer metal sleeve 10A (defining the side wall and the bottom), the material and the texture of which are mainly chosen according to the appearance that one wishes to give to the vial and an inner cage 10B, for example formed of plastic.
  • the cage 10B also represented on the Figures 9 and 10 , comprises a bottom 10C and three uprights 10D, 10E, 10F which are arranged in three of the four dihedrals of the side wall of the sheath.
  • the outer contour defined by the three amounts of the cage has dimensions substantially equal to the inner dimensions of the sleeve, so that the cage can be housed in the bottom of the sleeve.
  • the inner contour defined by the three amounts of the cage has a circular envelope to allow the guiding of a reservoir 20 which will be described later.
  • the set has a height which is defined by the height of the sheath and the movement of the tank inside the body. This will be described in more detail later.
  • the three uprights can be interconnected by cross members distributed over the height of the cage. The opening of the cage which is in the dihedral devoid of amount allows the release of the part during injection and also allows the assembly of the reservoir and the elastically compressible assembly inside the cage.
  • the cage 10B is housed in the bottom of the sleeve 10A, and these elements are assembled by any appropriate means and in particular by bonding with a hot melt glue. Other means may also be suitable. As has been said above, the sheath and the cage can be monobloc.
  • the reservoir 20 contains a fluid, that is to say liquid or viscous, to be applied using the application element 40.
  • the product is represented under the reference 100 in FIG. figure 8 .

  • This reservoir comprises a bottom 21 and an edge 22; its section is shaped so as to be able to slide (by simple displacement of translation) between the amounts of the cage between two longitudinally offset configurations, one of which corresponds to a maximum depression in the body towards the bottom of the body and the other corresponds to a minimum sink in this body.
  • This tank is designed so as to be entirely contained in this body over the entire travel between these two recess configurations. The height of the tank is therefore lower than the height of the body less the amplitude of displacement of the tank between its two driving configurations.
  • the reservoir has a circular general section, as shown in FIG. figure 9 . It is possible that the wall locally has a shoulder marked by a change in the diameter of the reservoir, such as the shoulder 23 which will be described later. Internally, the tank also has a circular section. This form of section is however not limiting, it is preferred because it allows a better return of the product.
  • the elastically compressible assembly 30 interposed between the cage and the tank is designed, in a manner known per se, to give the tank two stable positions of recoil with respect to the maximum driving configuration: in the figure 1 , the reservoir is, relative to the body, in one of these stable positions which is described as “stable low recoil position", that is to say in a stable position close to the maximum recess configuration; in the figure 2 , the reservoir is, relative to the body, in the other stable recoil position, which is a "stable high recoil position" and which corresponds to the minimum recess configuration of the aforementioned tank.
  • the assembly 30 comprises in practice a spring 31 compressed longitudinally between the bottom 11 of the body and the reservoir (here between the bottom 10C of the cage and the shoulder 23 formed externally in the wall of the tank), combined with a follower pin 33 carried by the tank along a track 34, represented in particular figure 9 , dug in the amount of the middle of the cage, the amount 10E, and at least a portion is inverted heart shape.

  • the low stable recoil position of the tank is defined by the positioning of the follower pin 33 at the dead point 34A of the track.
  • the high stable position of recoil is defined by the circulation of two diametrically opposed skids protruding from the cage (only the skid 10G is visible in the figure 9 ) which circulate in two diametrically opposite grooves hollowed on the outer surface of the tank 20 (only the groove 24 is visible in the figure 9 ).
  • the pads are in abutment against the lower end of the grooves and the spring 31 is not fully relaxed, it exerts a thrust between the cage and the reservoir.
  • Other modes of construction may also be suitable for limiting the stroke of the reservoir to the free edge 12 of the body.
  • the applicator element 40 comprises a rod 41 terminated by an applicator 42 adapted to be loaded with product when it is immersed in the reservoir in a so-called "closure" configuration with respect to this reservoir. At the other end is the cap 50 through which a user holds the applicator element during use.
  • the applicator 42 is of a known type and will not be described in detail. It can be spatula, brush, brush or any other suitable type. It is attached to the end of the rod, or it can be made in one piece with the rod.

  • the cap 50 is integral with the applicator element 40, but is generally formed of a part distinct from this element.
  • the rod 41 is surmounted by a head which is force-fitted to the inside the cap but, alternatively, it may be a single piece, if the production technique allows.
  • the reservoir 20 is provided on its free edge 22 with a peripheral insert 25 in which an inner insert 26 is mounted. Because of the respective functions of these two parts, the inner part 26 is a material having a rigidity. less than that of the peripheral part 25.
  • the peripheral piece 25 comprises a lower part 25A (with reference to the direction ZZ), of generally cylindrical shape and which is forcibly engaged in the upper part of the reservoir near the free edge 22, and a top part 25B which protrudes laterally out of from the reservoir to the inner wall of the body, thus closing the space located laterally between the outer wall of the tank and the inner wall of the body while being able to slide along the inner wall during movement of the tank inside.
  • an overhanging portion 25E of this upper portion 25B whose shape and dimensions substantially correspond to those of the body at its free end 12, can be likened to a circumferential sliding lip adapted to follow the inner wall of the body.

  • the annular rib 46 is here formed around the flared portion 45.
  • This wall of the intermediate portion may comprise a hollow area such as a groove adapted to receive at least in part this annular rib.
  • the flared portion may be connected to a hollow zone adapted to cooperate with a raised zone formed on the wall of the intermediate portion.
  • the flared portion 45 of the rod and the annular rib 46 seal the reservoir when the applicator is in the closed position ( figure 1 ).
  • the flared potion 45 also acts on the finger 25C during closure of the bottle in the case where the finger has approached the ZZ axis, this will be described in more detail later.
  • the flared portion 45 is connected to a convergent upper portion 47 of the enlarged portion 44 which converges towards an upper part of the rod.
  • the convergent portion 47 which lies below the level of the finger 25C in the closed configuration ( figure 1 ), is intended to move the finger from the ZZ axis to its position of the figure 2 when the tank rises after leaving its maximum driving position.
  • the free end of the lower part of the double skirt is facing transversely of a portion 48 of the rod which locally has a reduced section.
  • the finger 25C which is above the level of the enlarged portion 44, is retained in its position close to the axis ZZ by the lateral bearing surface 15. It retains the applicator by opposing the passage of the enlarged portion 44. Furthermore, the seal is provided by the cooperation of the outer surface of the enlarged portion 44 and the inner surface of the upper portion 26C of the double skirt of the part 26. These two functions are however independent .
  • the closure configuration is a configuration in which the inner portion of the cap is in longitudinal support against the upper part 25B of the peripheral part 25; however, the existence of such a longitudinal support could be made in another place, or even not exist, without affecting the locking and sealing effects described above.
  • the height h of the cap 50 is substantially equal to the stroke of the reservoir between its stable configuration maximum depression and its minimum recess configuration so that in the first position the cap is flush with the free edge 12 of the body, and that in the second position, the cap offers sufficient grip to be grasped between the fingers of one hand and extracted from the tank.
  • the lateral bearing surface 15 extends from the cam surface 16 to a depth in the reservoir which is greater than the stroke of the reservoir between its high stable position and its maximum driving configuration, so that, at least in the lower part of the reservoir stroke, the applicator and the reservoir are coupled to each other.
  • the position of the cam surface 16 is not critical. This position determines when the reservoir stroke the applicator and the reservoir are coupled to each other or when this coupling is released.
  • the applicator element is in its closed configuration in the reservoir, while this reservoir is in its stable low recoil configuration in the body.
  • the cap is then retracted into the body and therefore offers no grip to the fingers of a user who would like to apply traction to the outside; it is understandable that the same comment would apply if the cap came only a short distance projecting out of the body.
  • the lateral bearing surface 15 extends downwards over a distance such that the descent of the tank from its configuration of the figure 1 in its maximum driving configuration is possible without damaging the finger 25C.
  • the locking can be done by recoil of the finger inside the body has the advantage that the reservoir can remain completely inside the body in its stable configuration of minimum recoil. It has been seen that, in the example shown, the piece 25 closes the lateral space between the reservoir and the body; this closure is advantageously ensured, in the minimum recess configuration of the reservoir of the figure 2 (or the figure 3 ), at the free edge 12 of the body, that is to say that the widest part of the part 25 is then advantageously at the same level as the free edge.
  • the level at which the cam surface 16 is located can be freely selected by the designer of the bottle, but preferably this level is located rather towards the maximum driving position than towards the minimum driving position, and by For example, the cam surface is located so as to cooperate with the head of the finger at a distance at most equal to one-third of the displacement of the reservoir inside the body from the low rest configuration.
  • the convergent surface 47 pushes the finger 25C. And if by chance the finger approaches the ZZ axis while the applicator element is out of the reservoir, then it is the flared bottom portion 45 which repositions the finger in the right position at the moment when the applicator is re-introduced into the tank.
  • the distance from which the cap projects out of the body is substantially its height h (see figure 2 ).
  • the peripheral piece does not rise to the level of the free edge of the body without the operation described below being substantially modified (see figure 4 ).
  • the applicator element separates and deviates longitudinally with respect to the reservoir.
  • the lower part of the double skirt of the piece 26 is slightly elastically biased because the diameter of the rod is advantageously chosen to a value slightly greater than the diameter of the section delimited by the lower free edge of this lower part when it is not biased towards the tank wall. There is therefore a slight scraping of the product that may have attached to the stem.
  • this lower part is biased elastically by the applicator 42; since it has in practice a section greater than that of the rod, it is understood that the free edge of the lower part of the double skirt provides scraping (or spinning) of the applicator to detach the excess product which is attached to it. The user can then apply the product as she wishes, where she wishes.
  • the user When the user wants to reload the applicator product, it plunges the applicator into the tank as is done with a usual bottle.
  • the tank is kept in a high stable position by the spring thrust and does not move significantly relative to the body.
  • the locking function is dissociated from the sealing function and that these functions are activated by very moderate forces, regardless of the longitudinal position of the reservoir in the body, without any part the tank has to leave the body, longitudinally or laterally in any position of the tank.
  • the spinning effect provided by the lower part of the double skirt is obtained while this lower part extends over a short longitudinal distance; the inner piece 26 has a simple shape and is easy to manufacture; likewise the peripheral piece has a simple shape and is easy to manufacture.
  • the geometry of the enlarged portion of the stem it is also simple. The number of single pieces is only three, namely the peripheral piece 25, the associated finger 25C mounted thereon, and the inner piece 26.
  • the figure 4 represents an alternative embodiment of a bottle according to the invention.
  • the elements of this bottle, noted 101 as a whole, which are similar to those of Figures 1 to 3 are designated by reference signs which are deduced from the reference signs of these Figures 1 to 3 by adding the number 100.
  • This bottle 101 thus comprises, like the bottle 1, a body 110, a reservoir 120, an elastically compressible device with two stable recoil positions 130, an applicator element 140 and a cap 150.
  • the cap 150 differs slightly from the cap 50 by the geometry of its internal structure, in particular as regards the fact that it is by a peripheral part that this internal part bears against the upper surface of the piece 125, without this have an effect on the operation described above; the space between the surface external of the upper part 126C of the double skirt of the piece 126 and the inner surface of the piece 125 is larger than in the bottle 1, which has the effect of allowing greater lateral deformation of the upper part while facilitating the mounting of the inner part 126 on the peripheral piece 125.
  • the reservoir 120 of the bottle 101 does not rise until the periphery of the piece 125 is flush with the free edge 112 of the body, but remains below this edge by a distance denoted d . Accordingly, when the reservoir is in its minimum recess configuration, the cap does not come completely outside the body, but it is sufficiently high relative to the body to allow its grip.
  • the reservoir and the body have facing surfaces which are shaped so as to ensure retention of the reservoir in the upper position in the body.
  • the cage 110B that comprises the body 110 comprises, in at least one zone, here in an upper zone situated approximately at the level of the lateral bearing surface 115 under the cam surface 116, but being displaced circumferentially ( here right in the figure 4 ), a projection 117 in the direction of the rod, while the outer surface of the tank has a projection 118 adapted to come just above this projection 117 when the tank is in its minimum recess configuration.
  • At least one of these protrusions, here projection 118 is connected to an inclined surface 119 forming a contact surface for the other protrusion during a relative movement of mounting of the reservoir relative to the body.
  • the projection 117 slides on the inclined surface which gives a braking effect.
  • the rise of the tank under the thrust of the spring is slowed down this way.
  • Other construction methods may also be suitable.
  • the projection 118 crosses the hump formed by the other projection, so we have a hard point effect. This hard spot effect is also felt when the bottle is closed when the user presses on the cap 150 to retract it into the body.
  • the projection 117 is located above an area in which guiding elements may be provided to ensure a good guiding of the reservoir in the body without risk of rotation.
  • the inserts are obtained here by molding plastic materials, for example a thermoplastic material (polyamide, PVC or low-density polyethylene, in particular) or an elastomer material with high rigidity with respect to the peripheral piece and an elastomeric material for the workpiece reported internally. Alternatively they could form only one part made in mono or bi-injection.
  • plastic materials for example a thermoplastic material (polyamide, PVC or low-density polyethylene, in particular) or an elastomer material with high rigidity with respect to the peripheral piece and an elastomeric material for the workpiece reported internally.
  • a thermoplastic material polyamide, PVC or low-density polyethylene, in particular
  • an elastomer material with high rigidity with respect to the peripheral piece and an elastomeric material for the workpiece reported internally.
  • they could form only one part made in mono or bi-injection.
  • FIGs 5 and 6 represent in perspective the bottle 1 in the retracted configuration of the figure 1 , or in the extension configuration of the figure 2 , respectively. It will be appreciated that the section of the body and the cap is square with slightly curved edges; since the movement of the application element can be engaged by simple translation in the tank it is indeed possible to give the body any desired section (polygonal, oval, or clover-shaped, etc.).
  • the tank a similar shape (for example slightly smaller than that of the body) or on the contrary a different shape, for example a circular section, leaving, laterally, between the inner surface of the body and the external surface of the tank a space having a maximum width facing the edges of the body, which accommodates guide elements, or a portion of the elastically compressible device to two stable positions of recoil.
  • the cap offers the outside (to the fingers of a user or to an object that would come into contact with the bottle, for example in a bag) insufficient intake to extract the application element out of the body, or to push on this cap until the tank is in its maximum sink configuration.
  • the face of the cap which is accessible to the outside is curved, resulting in a slight protrusion of e .
  • FIGS 9 and 10 showing perspective views, allow to better appreciate the constitution of the cage 10B, the spring 31, the follower pin 33, and the reservoir 20. It is particularly easier to observe that the cage 10B has three uprights positioned here to three of its four corners, with the middle amount, the amount 10E which has no amount opposite, which includes the track 34, and the amount 10F which is extended by the enhancement which ends with the inclined surface 16 and the lateral bearing surface 15.
  • the invention is not limited to the modes of construction that have been described. It applies generally to any cosmetic product dispenser where the liquid or pasty product is applied using an applicator.
