Description

The present invention relates to packaging devices and

  of application of a cosmetic product, including of care, and more particularly but not exclusively those intended for the application of a nail varnish.

  The bottles of nail polish encountered on the market have various capacities, most often between 7 and 14 ml. Associated applicators include a rod with a brush at one end and a closure cap having a threaded portion.

  For bottles of relatively large capacity, for example 12 ml or more, the height of the body of the bottle allows the use of a relatively long rod. On the other hand, for the bottles of smaller capacity, the height of the body of the bottle is less and the stem must be shorter, except to shorten the length of the bristles of the brush and lose flexibility and quality of application or increase the neck length, which is inconvenient for the aesthetics.

  However, it is desirable to have both relatively long bristles and an apparent stem length which is not too short in order to facilitate application.

  1 5 The invention aims in particular to meet this need.

  It achieves this thanks to a packaging and application device comprising: - a bottle having a threaded neck, - an applicator comprising: - a rod, - an application element disposed at a first end of the rod, - a capsule closure supporting the rod at a second end opposite the first, this closure capsule comprising a threaded portion arranged to be screwed onto the neck, this device being able, according to a first aspect of the invention, to be characterized in that the closure cap comprises a ring removably connected to the threaded part and arranged so as to remain integral with the neck when the applicator is removed.

  Thanks to the invention, it is possible to benefit from an apparent length of rod plus relatively large application element, without however detracting from the aesthetics of the bottle, thanks to the ring present at the base of the neck. In addition, the establishment of the ring can be carried out in a relatively easy and economical manner, after filling the bottle.

  It is also possible to produce the ring and the threaded part so as to give the impression of a closure capsule produced in one piece when the applicator is in place on the bottle, which may be favorable from an aesthetic point of view.

  The expression "threaded part" must be understood in a broad sense as corresponding to the part of the closure capsule which carries at least one thread, the latter being able to be produced if necessary on an insert fixed in an over-cap. In this case, the ring can be removably connected to the insert or to the overcap.

  The ring may or may not have a thread.

  In a particular embodiment, the ring comprises at least a first relief 10 allowing its fixing by snap-fastening on at least a second relief produced on the neck.

  This second relief can for example comprise an annular bead and the first relief include an annular bead or teeth projecting from the radially inner surface of the ring.

  The ring may also include at least one relief arranged to frictionally retain the ring on the neck. The ring may in particular have ribs on its inner surface.

  The ring can advantageously be produced at least partially by plastic molding with the threaded part, in particular with the overcap when the threaded part includes an insert and an overcap. The ring can be connected by bridges of breakable material to the threaded part.

  The ring can also be arranged on the threaded part by being attached thereto, the threaded part and the ring being for example made in different molds.

  The ring may for example have a relief allowing it to cooperate by interlocking with the threaded part. The ring may thus not be connected to the threaded part by bridges 25 of breakable material.

  The ring and the threaded part can also be connected to each other by other fixing means.

  The neck may comprise at least a first anti-rotation relief and the ring at least a second anti-rotation relief arranged to cooperate with the first relief so as to prevent the ring from rotating relative to the neck during unscrewing of the closure cap leading to the separation of the threaded part and the ring.

  This first relief, produced on the bottle, can be arranged to allow it to be crossed by the second relief during the initial screwing of the closure cap on the bottle. At least one of the first and second reliefs may include a ramp facilitating this crossing.

  Immobilization in rotation of the ring on the neck can also be obtained by tightening the ring on the neck, especially when the ring has ribs on its inner surface.

  The neck may have at its base a cylindrical surface or a frustoconical surface widening towards the body of the bottle, on which the ring can come to bear with a certain tightening.

The ring can be decorated.

  The bottle can be produced with various shapes and in particular with a shoulder at the base of the neck.

  The bottle can be made of glass or plastic, and in particular can be made of a transparent material.

  The capacity of the bottle can be less than or equal to 10 ml, in particular less than or equal to 8 ml, for example between about 7 ml and about 5 ml.

  The apparent length of the rod and of the application element may for example be greater than or equal to 25 mm. In the case where the application element is a brush, the apparent length of the free part of the bristles is for example greater than or equal to 12 mm.

  The bottle may for example contain a product to be applied to the nails, in particular a nail varnish. The bottle may also contain a product to be applied to the face, in particular to the lips. In this case, the bottle may in particular include a wiper member.

  The application element can be flocked, in particular for application to the skin or the lips.

  The length of the rod can be substantially equal to the height of the neck, the length of the rod being for example equal, to within 30%, to the height of the neck.

  The length of the applicator element may be substantially equal to the height of the body of the bottle, to which the neck is connected; the length of the application element can thus be equal, for example, to 30% near the height of the body.

  The subject of the invention is also a method of manufacturing a packaging and application device comprising the following steps: screwing onto an flask comprising a threaded neck an applicator comprising: a rod, - an application element arranged at a first end of the rod, - a closure capsule, the rod of which is integral with a second end, opposite the first, this closure capsule comprising a threaded part arranged to be screwed onto the neck, the closure capsule comprising at its base a ring removably connected to the threaded part, the neck and the ring having shapes arranged to cooperate in order to retain the ring on the neck when the threaded part is unscrewed, at the time of use.

  The neck and the ring can in particular cooperate by snap-fastening or by friction.

  A further subject of the invention is a method of manufacturing a packaging and application device, comprising the following steps: screwing a threaded insert to a bottle having a threaded neck, of which the application element is integral, add an over-cap on the insert, the over-cap being connected to a ring in a removable manner, the over-cap and the insert remaining integral when the insert is unscrewed, the neck and the ring having shapes arranged to cooperate in order to retain the ring on the collar when the insert is unscrewed.

  The invention will be better understood on reading the detailed description which follows, of nonlimiting examples of implementation of the invention, and on examining the appended drawing, in which: - Figure 1 shows in schematically elevating an example of a packaging and application device produced in accordance with the invention, - Figure 2 is a view similar to Figure 1, showing the device during the initial unscrewing of the closure cap, - Figure 3 is a view similar to FIG. 1, showing the applicator 30 completely withdrawn from the bottle, - FIG. 4 represents the bottle in isolation, without the ring or the rest of the closure cap, - FIG. 5 is a schematic axial section of the bottle of Figure 3, provided with the ring, - Figure 6 shows schematically and partially, in axial section, the closure capsule of the device of Figures 1 to 3, - Figures 7 and 8 are axial sections sc thematic and partial alternative embodiments of the closure capsule, - Figure 9 is an exploded, schematic view of another example of implementation of the invention, - Figure 10 shows the device of Figure 9 after screwing the insert 10 onto the neck of the bottle, - Figure 11 shows the device in Figure 10 after fitting the overcap and the ring, - Figure 12 shows the device in Figure 11 after removing the applicator, - Figure 13 shows in isolation and schematically an alternative embodiment of the bottle, - Figure 14 shows an applicator comprising a flocked application element, - Figure 15 is a schematic and partial axial section of a bottle 20 in accordance with an alternative embodiment, this bottle comprising a wiping member, FIGS. 16 to 18 schematically and partially, in elevation, closure capsules in accordance with variants of implementation of the invention, and - Figure 19 shows in isolation and schematically an overcap 25 having an outer non-circular cross section.

  The packaging and application device 1 shown in Figures 1 to 3 comprises a bottle 2, made for example of glass or plastic, and an applicator 3 comprising a rod 4, provided at its lower end with an element of application 5 such as for example a brush, and connected at its upper end to a closure cap 6, which has a threaded part 7 and a ring 8 in the lower part.

  The rod 4 is for example a hollow rod inside which the tuft of bristles of the brush is inserted, the apparent length I of the bristles being for example 12 mm or more.

  The rod 4 can be fixed inside the closure cap 6 in a conventional manner by means of an insert which optionally serves to further ensure a tight closure of the bottle.

  The threaded part 7 is intended to be screwed onto the neck 10 of the bottle 2, this neck 10 being provided with a thread 11.

  According to one aspect of the invention, the ring 8 is initially secured 10 to the threaded part 7 when the applicator 3 is put in place for the first time on the bottle 2.

  The ring 8 can for example be produced, as seen in FIG. 6, in one piece by molding plastic material with the threaded part 7, the two being connected by one or more bridges of breakable material 13. We see in this figure that the 15 material bridges 13 are set back from the radially outer surface 19 of the ring 8, so as not to harm the aesthetics of the capsule.

  The ring 8 also comprises in the example considered at least one first relief 15, for example a bead or teeth projecting from its radially inner surface 16, and the neck 10 of the bottle 2 has at its base at least one second 20 relief 18 arranged to allow the latching on the neck of the ring 8 at the end of the initial screwing of the closure cap 6 on the bottle 2.

  So as to allow during the unscrewing of the closure cap 6 to the ring 8 to separate from the threaded part 7, at least one anti-rotation relief 20 is produced on the radially inner surface 16 of the ring 8, so as to cooperate with at least one complementary relief 21 produced on the neck 10. The reliefs 20 and 21 are arranged so as to allow the relief 20 to cross the relief 21 during the initial screwing of the closure cap 6 and the reliefs 20 and 21 for example, have respective ramps 23 and 24 for this purpose. The latter are inclined so as to help the relief 20 to cross the relief 21 in the direction of screwing on the closure cap, the reliefs 20 and 21 preventing a new crossing. In the opposite way.

  When the user unscrews for the first time the closure cap 6, the threaded part 7 separates from the ring 8, which remains permanently on the neck 10 and the user can benefit from an apparent length 1 ′ of rod 4 sufficient to allow proper application of the product, for example on the nails.

  Of course, the invention is not limited to the embodiment which has just been described. One can in particular make various modifications to the bottle and to the closure cap.

  For example, the closure cap can be produced with a threaded portion 7 and a ring 8 which are connected by bridges of material 13 directed substantially radially, as seen in FIG. 7, and no longer substantially axially as shown. shown in Figure 6.

  The ring 8 and the threaded part 7 can also be connected other than by bridges of breakable material before mounting the closure cap 3 on the bottle 2.

  For example, there is shown in Figure 8 an alternative embodiment in which the threaded portion 7 and the ring 8 are arranged to cooperate by interlocking, the ring 8 being for example provided with an annular rib 33 adapted to s 'Engage in a shouldered housing 24 made at the lower end of the threaded part 7.

  We will now describe with reference to Figures 9 to 12 an alternative embodiment in which the closure capsule comprises an insert 40 and an over-capsule 41 inside which the insert 40 can be fixed.

  The insert 40 has internally a thread 42 intended to allow it to be screwed onto the neck 10 and a housing 43 allowing the upper end 44 of the rod 4 to be fixed on the insert 40.

  The latter comprises a flange 45 intended to come to bear on the edge of the neck 10 at the end of the screwing of the insert 40, in order to seal the bottle 2 tightly.

  The over-cap 41 has on its radially inner surface axial ribs 48 intended to allow the clamping of the over-cap 41 to the insert 40, the two parts then being stationary relative to one another.

  The ring 8 is produced in the example considered in one piece with the overcap 41, being connected thereto by bridges of material 13 located in the extension of the ribs 48.

  The ring 8 has on its inner surface axial ribs 50 located in the extension of the ribs 48, intended to come to bear on an enlarged portion 56 at the base of the neck 10, with sufficient tightening so that the ring 8 is then immobilized in rotation relative to the bottle 2.

  After filling the bottle 2, the insert 40 and the rod 4 can be put in place so as to close the bottle, as illustrated in FIG. 10, then the assembly constituted by the overcap 41 and the ring 8 can be attached to the insert 40, until the insert 40 comes to bear against the bottom of the top wall of the overcap 41, the ribs 48 being applied with clamping to the insert 40.

  The bottle 2 provided with the closure cap has been shown in FIG. 1.

  During use, the user unscrews the threaded part 7 composed of the overcap 41 and 10 of the insert 40, the ring 8 remaining on the neck 10 of the bottle by tightening the ribs 50 on the enlarged part 56, as it can be seen in FIG. 12. It will be understood on examination of this figure that thanks to the fact that the ring 8 remains on the neck 10 of the bottle 2, it is possible to gain in apparent length of rod the equivalent of the height h of the ring 8.

  We do not depart from the present invention when the neck 10 is made with, at its base, not a cylindrical surface of revolution but a frustoconical surface. By way of example, there is shown in FIG. 13 the bottle 2 of the exemplary embodiment of FIGS. 1 to 5 with at the base of the neck 10 a frustoconical lower part 32 allowing for example to increase the tightening between the ring 8 and the bottle 2.

  The applicator element 5 may consist of something other than a brush and, by way of illustration, a flocked applicator element has been shown in FIG. 14, intended for example for application to the lips. .

  The bottle 2 can be produced by assembling one or more parts and in particular comprising a wiper member 60 as illustrated in FIG. 15. It can be seen in this figure that the bottle 2 can comprise a body 61 on which a part is attached 25 62 defining the neck 10 of the bottle and making it possible to support the wiper member 60, which can be constituted for example by a block of foam split axially in order to allow the passage of the application element 5. In this example , the bottle 2 can be filled with a product P intended for example to be applied to the lips.

  The closure cap 6 can be produced with various shapes, as can be seen in FIGS. 16 to 18, its external section possibly being circular or not, in particular prismatic.

  By way of illustration, FIG. 19 shows an overcap 41 having a substantially square outer cross section. This overcap can be produced internally with a cylindrical wall 63 of revolution, intended to allow the attachment of an insert carrying the thread of the closure cap and the rod.

  Throughout the description, including the claims, the expression "comprising a" must be understood as being synonymous with "comprising at least one", unless otherwise specified.
