Description

The present invention relates to devices for packaging and applying a fluid product, for example make-up of the skin, mucous membranes or integuments, for example mascara.

The invention can be applied inter alia to packaging and application devices comprising a wiper member and means for acting thereon to modify its inner section and spin more or less an applicator engaged through it.

Such devices are known for example from the patent application French FR 2 515 941 and the patent US 4,194,948 .

In the patent application French FR 2 515 941 , the container has an externally threaded neck on which is screwed a ring which can more or less compress the hourglass-shaped wringing member and thus change its inner diameter. The closure tightness of the device can be obtained by compressing the wiper member fully on the rod of the applicator.

The patent US 4,194,848 describes a device comprising a setting ring screwed into an insert inserted into the neck of the container.

There is a need to benefit from a device allowing for example to act on a dewatering member, a flow reducer or a shutter, whose components are relatively simple to manufacture and assemble, and which is moreover Reliable and easy to use.

The invention can meet this need.

• un premier élément ayant un axe, qui peut être un axe longitudinal, et comportant au moins une fente s'étendant non entièrement perpendiculairement à cet axe,
• un deuxième élément au moins partiellement engagé à l'intérieur du premier, pouvant tourner par rapport à celui-ci autour de l'axe précité et pouvant également se déplacer axialement dans le premier élément, ce deuxième élément comportant au moins un ergot engagé dans la fente, cet ergot étant visible depuis l'extérieur du dispositif, la fente et l'ergot étant configurés de telle sorte qu'un déplacement de l'ergot dans la fente lors de la rotation relative des premier et deuxième éléments provoque un déplacement axial relatif de ces deux éléments.

According to one of its aspects, the subject of the invention is a packaging and / or application device comprising:

• a first member having an axis, which may be a longitudinal axis, and having at least one slot extending not entirely perpendicular to that axis,
• a second element at least partially engaged within the first, rotatable relative thereto around the aforementioned axis and also able to move axially in the first element, this second element comprising at least one lug engaged in the slot, this lug being visible from the outside of the device, the slot and the lug being configured so that a displacement of the lug in the slot during the relative rotation of the first and second elements causes a relative axial displacement of these two elements.

• servir d'indicateur renseignant l'utilisateur sur la position relative des premier et deuxième éléments,
• retenir axialement le deuxième élément dans le premier, et
• transformer une rotation du deuxième élément en un déplacement axial de celui-ci relativement au premier élément.

Thanks to the invention, the lug can advantageously play a triple function, namely:

• serve as an indicator informing the user on the relative position of the first and second elements,
• axially retain the second element in the first, and
• transforming a rotation of the second element into an axial displacement thereof relative to the first element.

This results in a construction device relatively simple and convenient to use.

The lug may be unique, and have any shape, for example of circular section or not, being monolithic or not.

The device may comprise on its outer surface at least one apparent mark associated with a particular relative position of the first and second elements, for example several marks corresponding to different positions of the pin in the slot, each mark comprising for example at least one alphanumeric character or pictogram.

The slot extends for example angularly less than 180 °, for example about 120 °, around the aforementioned axis.

The slot may have at least one smooth or notched edge. The presence of at least one notch may facilitate, if necessary, the positioning of the second element relative to the first in at least one predefined position.

The existence of at least one notch may also form at least one hard point whose crossing by the pin is perceptible by the user and, where appropriate, may be accompanied by the emission of an audible click. .

The presence of at least one notch can further facilitate the maintenance of the lug in a predefined position during the transport of the device, in a handbag for example.

The slot may have an inclination, relative to the axis, chosen so that the axial stroke of the second element in the first, between the extreme positions of the lug in the slot, is between about 1 mm and about 10 mm, for example between 1 mm and 8 mm, for example still between 2 mm and 5 mm.

The lug may have a length that is greater than or equal to the thickness of the wall of the first element traversed by the slot, which can improve the retention of the second element in the first element and the visibility of the lug.

The lug can still have a length less than the thickness of the wall of the first element through which the slot, which can facilitate its implementation.

The first and second members may be arranged to allow insertion of the lug into the slot by elastic deformation of at least one of the first and second members when the second member is moved within the first member.

The first element may have on its inner surface at least one notch that can facilitate the movement of the lug between the end of the first element for introducing the second element and the slot. This notch may for example lead to the aforementioned end.

The lug can have a free end rounded or chamfered, which can improve the aesthetics and facilitate its implementation in the slot.

The first element can be made in one piece by molding plastic material. The same can be said of the second element.

In an exemplary implementation of the invention, the second element has an end portion that extends continuously out of the first element. This end portion may include an outer skirt, which may be striated or grained to facilitate its training by the user.

The second element may also include a body that is closed at one end. When the end portion has an outer skirt, the outer skirt may be arranged to extend around the bottom of the body.

The body may contain a product, especially a cosmetic or dermatological product, for example mascara.

The device may include an applicator for applying a product contained in the device and this applicator is for example fixed on the first element.

The applicator may in particular be removably attached to the first element to be extracted from the device for the application and then reintroduced into the device to be reloaded product.

The applicator may comprise an application element arranged to be housed in the second element when the applicator is in place.

The applicator may comprise a gripping member arranged to attach to the first element, for example by screwing.

The applicator element may be connected to this gripping member by a rod, which may optionally be made in one piece by molding plastic material with the gripping member. The rod can still be provided at one end with a tip engaged in the gripping member.

The device may comprise, in embodiments of the invention, a deformable element arranged to be deformed more or less according to the relative positioning of the first and second elements. This deformable element may comprise an insert or be made monolithically with one of the first and second elements.

The deformable element is for example a wiper member arranged to be able to at least partially wring the aforementioned applicator during removal thereof.

The deformable element is for example disposed on one of the first and second elements, being for example fixed on the second element, and can be deformed by the other element according to the relative axial positioning of the two elements.

The deformable element can be arranged to deform in elongation or compression. The deformable element may be arranged to deform in spacing.

In the case of an elongation deformation and in the case where the deformable element constitutes a wringing member, the deformable element comprises for example a central portion provided with a transverse wall, for example a bottom wall, crossed. by an opening and the first element may comprise an inner extension which bears more or less on this bottom wall according to the relative positioning of the first and second elements and thus modifies the shape of the opening, for example by widening it more or less .

In the case of compression deformation, the elastically deformable element is for example made of an elastically compressible material such as a foam.

This elastically compressible material may have a hardness that depends on its degree of compression, which may allow the user to modify the characteristics of the spin, for example.

At least when the deformable element constitutes a wiper member, the deformable element may comprise a flange defining with the central portion an annular groove in which is engaged the second element.

The aforementioned transverse wall may comprise at least one slot facilitating the deformation of the wiper member by pressing against it the extension of the first element. The transverse wall may for example comprise a plurality of substantially radial slots.

The inner extension of the first element acting on the deformable element can be made in one piece by molding material with the rest of the first element. This inner extension may have a tubular shape. The inner extension can play a spin function as well, if necessary.

In an exemplary implementation of the invention, the deformable element comprises a plurality of molded tongues with one of the first and second elements and the other of the first and second elements has a surface against which these tongues can come to bear according to the relative axial positioning of the first and second elements.

The aforementioned surface is arranged so that the tabs flex more or less according to the relative axial positioning of the first and second elements.

The tabs define an opening for wringing the applicator member, and this opening may thus have a dimension that the user can vary by rotating the first member relative to the second member. The surface serving to support the tongues is for example conical, converging towards the interior of the container.

The first element may comprise a generally cylindrical outer wall, through which the slot passes, and this outer wall may have, for example, substantially the same external diameter as the end portion of the second element.

The applicator may comprise a rod provided with a necking in a region of the rod which is positioned, when the device is closed, facing the wiper orifice. This shrinkage may extend over a length greater than or equal to the stroke of maximum displacement of the second element relative to the first. This can avoid or reduce the stresses exerted by the rod on the wiper member when the applicator is in place, regardless of the angular orientation of the first element relative to the second.

The elastically deformable member may still not serve as a wiper member but a closure member and / or flow control being configured to close at least partially a communication between the outside and inside of the body of the second element in a first relative position of the first element and the second element and less obturate this communication for a second relative position of the first and second elements, the transition from one position to the other corresponding to a displacement of the pin in the slot.

In an exemplary implementation of the invention, the first relative position corresponds to a total closure.

In another example of implementation of the invention, the first relative position corresponds to a closure which is not total.

The application element is for example a brush, in particular a brush comprising a twisted metal core and bristles clamped between turns of the core. The application element may be different, for example comprise a flocked tip, a comb, a felt, a foam or be a brush without metal core.

The device 1 shown in Figures 1 and 2 comprises a first member 10 and a second member 20 rotatable relative to the first member 10 about the longitudinal axis X of the device.

The device 1 also comprises an applicator 30 which comprises in the example under consideration a pin 31 of axis X, provided at one end with an applicator element 32 and at the other end with a gripping member 33.

The first element 10 comprises, as can be seen in FIG. 2, a generally cylindrical wall 11, of axis X, prolonged in the upper part by a neck 12 which is connected below a transverse wall 13.

The first element 10 also comprises in the illustrated example an inner extension 14 of tubular shape, defining an introduction cone 15 for the applicator member, converging towards the inside of the container, and provided at its lower end with an annular bead 16.

The second element 20 comprises, in the example considered, a generally tubular body, of X axis, closed at its lower end by a bottom 22. The lower part 23 of the body 21 is surrounded by an outer skirt 24 whose surface outer is grained, as can be seen in Figure 1. It could alternatively (not shown) be striated.

The skirt 24 joins the transverse wall 25, which is connected perpendicularly to the body 21. The wall of the latter thickens above the transverse wall 25, so as to form a cylindrical guide surface 26, of suitable outside diameter. to the inner diameter of the lower end of the wall 11. The height of the guide surface 26 is sufficient so that, regardless of the angular position of the second element 20 relative to the first element 10, the surface 26 remains substantially in contact with the the inner surface of the wall 11.

The body 21 has in the upper part, on its radially outer surface, an annular bead 27 which serves to attach a wiper member 40. The latter comprises in the upper part an annular rim 41 arranged to snap on the bead 27. This flange 41 is connected to a tubular skirt 43 extending in the annular space formed between the inner extension 14 and the upper part of the body 21.

The wiper member 40 comprises in the lower part a transverse wall 45 traversed by a central orifice 46 and by a plurality of slots 47 forming between them tongues (or fins) 48.

In the variant illustrated in Figure 14, the transverse wall 45 is traversed by a single orifice 46 of circular section, without the slots 47. This may allow to obtain, if necessary, a sealed contact of the wiper member on the rod 31 of the applicator, storage for example.

The body 21 serves as a reservoir and contains a product P, for example mascara.

The second element 20 is provided with a lug 50 and the first element 10 has a slot 51 passing through the wall 11 and whose longitudinal axis Y extends for example along a portion of a helix, over an angular extent for example of Around 120 ° around the X axis.

FIG. 9 illustrates the possibility for the slot 51 to extend differently than in a single helix portion, and in FIG. 10 the possibility for at least one of the edges of the slot 51 to include notches 80. At least one of them may for example be associated with a reference 81 useful to the user, such as a number or a letter.

The inclination of the slot 51 allows for example a maximum stroke d in the axial direction of between 2 and 3 mm when the lug 50 passes from one extreme position to the other, after rotation of the second element 20 relative to the first element. 10.

When the second element 20 is in the lower stop position corresponding to FIG. 1, with the lug 50 bearing against the left end 53 of the slot 51, the lower end 19 of the inner extension 14 may not not deform substantially the wall 45 of the wiper member 40 and the fins 48 can extend maximally towards the inside of the circular orifice 18 defined by the lower end of the introduction cone 15, as one can be seen in Figure 5. The spin is maximum and the product load on the minimum application element.

The rod 31 may advantageously have, as illustrated in FIG. 2, an annular narrowing 35 whose diameter substantially corresponds to that of the circle C passing through the vertices of the fins 48 in the configuration of FIG. 5. Thus, the rod 31 exerts no constraints or even exerts only relatively small constraints on the wiper member, which reduces the risk of permanent deformation thereof.

When the second member is rotated in the direction of the arrow R in Figure 1, the lug 50 moves in the slot 51 and rises relative to the first member 10. The inner extension 14 bears down against the wall 45 and the fins 48 are spaced apart. The fins then extend over a smaller distance projecting inside the orifice 18, as can be seen in FIG. 6. At the end of the rotational stroke in the direction of the arrow R, the lug 50 reaches the high stop position corresponding to the half-section on the left in FIG. 2 and the fins 48 practically no longer project in the orifice 18, as can be seen in FIG.

In the example considered, the inner extension 14 does not cross the transverse wall 45. In a variant (not shown), the axial displacement stroke of the inner extension 14 is sufficiently large for it to pass entirely through the wiper member 40.

Those skilled in the art can choose the degree of deformation of the wiper member depending on the desired result, for example according to whether or not it wishes to maintain a spin regardless of the position of the pin in the slot, or to be able, for a given position, to run only on the edge of the inner extension.

For example, one can have two positions respectively corresponding to a spin on the elastically deformable wiper member and a spin on the inner extension. It is also possible to have in a variant for a position at least one absence of spin, by performing the inner extension so that it can not normally wring the application element.

Preferably, the necking 35 extends over a height h which is greater than the maximum axial stroke d of the second element relative to the first element, so that whatever the position of the lug 50 in the slot 51, c 'is always the shrinkage 35 which comes opposite the end of the fins 48. In a variant (not shown), the rod is devoid of shrinkage.

To assemble the device 1, the wiper member 40 is for example fixed on the second element 20, then the latter is introduced into the first element. To facilitate the passage through the lug 50 of the lower portion 55 of the first element 10, the wall 11 of the latter may advantageously comprise a notch 56 on its radially inner surface, opening for example at the lower end 58 of the wall 11. as shown in Figure 3.

The notch 56 may optionally have a ramp 85 which facilitates the passage of the lug, as illustrated in FIG. 12.

The lug 50 may have a rounded upper end 60, as shown in FIG. 8, in order to facilitate the crossing of this end portion 55.

In the variant illustrated in FIG. 9, the lug comprises a chamfer 61.

The notch 56 can be positioned relative to the slot 51 so that the pin 50, after the X-axis displacement in the notch 56, reaches a position adjacent to the end 53.

The length of the lug allows it, for example, to protrude slightly out of the slot 51, as can be seen in FIG. 8. In this figure, a discontinuous line illustrates the possibility, in a variant, of the pin 50 to have a reduced length to stay set back from the outer surface of the second element.

The lug may optionally be colored so as to appear more clearly, and may in this case be made for example by bi-injection of material with the remainder of the second element 20.

The rod 31 is for example engaged in a sub-capsule 70 of the gripping member, this sub-capsule 70 may comprise a mounting skirt 71 internally threaded, arranged to be screwed onto an external thread 72 of the neck 12.

The mounting skirt 71 can support an outer cover 73, for example metal.

The rod 31 may comprise, at its upper end, a series of grooves 75 allowing it to be pressed into the sub-capsule 70.

The latter can also comprise, as illustrated, a sealing lip 76 which is applied to the radially inner surface of the neck 12 at the end of the screwing of the sub-capsule 70 onto the neck 12. Of course, the gripping member could be fixed still further on the first element 10, for example by friction or snap.

The invention is not limited to a particular type of application element and the application element is for example other than a mascara brush, being for example a comb 90, a tip 92 flocked or not, for example elastomer, a felt 93, a foam 94 or a brush 91, as shown in Figure 13. The application element may be of greater transverse dimension smaller or larger than a diameter of the rod 31.

The wiper member may also be made differently and in particular not work in elongation but in compression, as shown in Figures 15 and 16.

In these figures, there is partially shown a device whose lower part not apparent is for example the same as that of the device of Figures 1 and 2 and whose upper part has been modified to accommodate the wiper member 40, made of an elastically deformable material.

The wiper member 40 rests on its lower face 101 against a shoulder 102 formed for example by an annular rib 103 of the body 21 and is supported by its upper face 104 against the lower edge 105 of an inner extension of the first element 10.

When the second element 20 is in the least engaged configuration in the first element 10, the wiper member 40 is only slightly or slightly compressed, so that it provides a relatively large opening 106, which is for example of a first diameter D ₁ .

When the second element 20 is angularly displaced relative to the first element 10 so as to further engage in this first element 10, the wiper member 40 is further compressed between the first element 10 and the second element 20 and the diameter of the first element 10. the opening 106 is reduced and passes to a second diameter D ₂ less than D ₁ .

If necessary, the wiper member 40 can be applied sealingly to the rod 40 when the diameter of the opening 106 is reduced, as illustrated in FIG. 17.

The wiper member may be further replaced by a flow reducer, or even by a shutter, the applicator being present or not.

By way of example, FIGS. 18 and 19 show a container 130 comprising a neck 131 provided with a lug 132. This neck 131 constitutes a second element within the meaning of the invention, the first element being constituted by a capsule 135 engaged on the neck 131 and provided with a slot 136 in which can slide the pin 132.

An elastically deformable member 140 is disposed inside the neck 131 and is supported for example by its lower face against a shoulder 137 of the neck.

The capsule 135 has an outer skirt 138 and an inner extension 139 that can bear against the elastically deformable member 140, at least when the lug 132 is in the closed position or small flow, so as to axially compress the organ deformable 140. The latter is traversed by an opening 141 whose section depends on the degree of axial compression.

When the deformable member 140 is a flow reducer, the opening 141 remains open even when the pin 132 is in the extreme position corresponding to the degree of maximum depression of the neck 131 in the capsule 135.

When the deformable member 140 is a shutter, as in the example illustrated, the opening 141 allows the passage of product only when the pin 132 has been moved in the slot 136 to the open position and that the compression force exerted axially on the member 140 is reduced.

The device may not comprise a deformable member interposed between the first and second elements but a shutter 161 carried by the neck 131, configured to close the dispensing orifice 163 of the capsule 135 for an extreme position of the lug 132 in the slot 136, as illustrated in FIG.

The wiper member may also be made at least partially monolithically with one of the first and second elements, as illustrated in FIG. 21.

The first element 10 is made in this example with an inner extension terminated by a plurality of flexible tabs 170, which are engaged in the second element and can abut against a surface 171 thereof. This surface 171 is for example conical, converging towards the bottom of the container.

The free ends of the tongues define an opening for the passage of the application element, the user can vary the diameter by changing the axial positioning of the first element relative to the second.

When the inner extension of the first element sinks into the second element, these tongues are deflected radially inwards, which decreases the diameter of the wringing orifice.

When the first element rises, the tabs tend to move apart due to their own elasticity, and the diameter of the wiper orifice increases.

When the tongues are sufficiently raised, the diameter of the wiping orifice can be defined by the radially inner edge of the surface 171.

The invention is not limited to the examples of implementations which have just been described.

The characteristics of the different embodiments described can in particular be combined with each other within non-illustrated examples.

The expression "having one" shall be understood as being synonymous with "having at least one", unless the opposite is specified.
