Definitions

  • the present invention relates to a device for packaging and applying a fragranced composition.
  • Fragrances are usually packaged in bottles, with an open neck or equipped with a pump or a valve for dispensing a spray.
  • Fragrance applicator pens are known, including a felt tip which is regularly soaked with the fragrance of choice, by dipping the tip into a bottle containing said fragrance. Refilling the pen remains a relatively laborious operation, which may put certain users off.
  • the invention aims to meet this need and achieves this by means of an applicator pen including:
  • a reservoir containing a fragranced composition comprising at least 1% by weight of fragrancing substance(s) relative to the total weight of the composition, and at least one volatile silicone oil,
  • a piston drive mechanism arranged to transform an action from the user on the actuating member into an advancement of the piston.
  • the fragranced composition is sufficiently viscous that it does not drip under the effect of its own weight out of the application member, when the applicator pen is not actuated.
  • the risk of leakage is thus minimized, and it becomes easier to measure out the amount of fragranced composition by greater or lesser actuation of the actuating member.
  • the viscosity of the composition is thus between 4 and 7 Pa.s, being measured at 25°C at a pressure of 1 atm, using a Rheomat 1 TVE-05 viscometer from Lamy Rheology.
  • the user can easily and precisely apply a touch of perfume to the area of his or her choice.
  • the application member is easy to refill with composition by acting on the actuating member. The drawbacks associated with the refilling of the felt application tip of the pens of the prior art are avoided.
  • applicator pens have been proposed for applying makeup compositions such as lipsticks or lip glosses, they have never to the Applicant's knowledge been used for applying a composition having a high content of fragrance.
  • FR 3 003 465 describes devices comprising a container in which is stored a composition and comprising an application member with a porous application surface.
  • this device is proposed for applying lip compositions.
  • the actuating member is preferably present at the opposite end of the pen to the application member.
  • the actuating member is displaceable relative to a body of the pen. The user can thus easily press with the thumb on the actuating member to dispense a dose of composition.
  • the drive mechanism may be arranged such that the reduction of the internal volume of the reservoir on each actuation of the actuating member is between 0.005 and 0.02 mm 3 , for example of the order of 0.01 ml.
  • the initial capacity of the reservoir is advantageously between 1 ml and 5 ml.
  • the application member may include or may consist of a brush in the form of a fine- detail brush.
  • the application member (20) includes a fine-detail brush.
  • the applicator pen may include a dispensing cannula which emerges into the application member, recessed from its free end. The cannula emerges, for example, at a distance of between 1/4 and 3/4 of the length of the application member, from its free end, better still between 1/3 and 2/3 of this length.
  • the presence of the cannula is advantageous in that it reduces the path of the composition inside the application member up to the tip, and thus makes it possible to minimize the volume of composition that it is necessary to inject into the application member before being able to apply the composition. Furthermore, the composition may be brought in this way to the very centre of the application member. The part of the application member located recessed from the cannula may contribute towards absorbing by capillary action an excess of composition, and may give the application member flexibility, where appropriate.
  • the cannula may also make it possible to ensure a loss of pressure between the application member and the reservoir and thus reduce the risk of leakages.
  • the presence of a flap valve or of a closing member other than the cap of the pen may be avoided.
  • the viscosity of the composition is such that it remains within the cannula without flowing under the effect of its own weight, when the applicator pen is held upside down.
  • the communication between the reservoir and the application member can thus be permanently open.
  • the cannula has, for example, a cylindrical portion, notably rotationally cylindrical, with a cross-section of between 0.5 and 2 mm 2 , for example with an inside diameter of between 1 and 1.2 mm. This portion is, for example, between 5 and 15 mm long.
  • the pen may include a ring which is mounted on the application member and, for example, fixed into a neck of the pen.
  • This ring surrounds the application member over a part of its length.
  • this ring presses the application member against the abovementioned cannula.
  • the presence of the ring ensures that the bristles of the abovementioned brush are held fast, and makes it possible to maintain the precision of the application despite the mechanical stresses to which the bristles of the brush may be subjected in the course of successive uses.
  • the cannula may be borne by an insert attached inside the ring.
  • composition contained in the reservoir is preferably an anhydrous composition.
  • anhydrous refers to a composition having a water content of less than 1% by weight, or even less than 0.5% by weight, relative to the total weight of the composition. Even more preferentially, a composition according to the invention is totally free of water.
  • water that may be present is more particularly bound water, such as water of crystallization in salts, or traces of water absorbed by the starting materials used in the preparation of the compositions of the invention.
  • the composition contained in the reservoir comprises at least 1% by weight of a mixture of fragrancing substances, in particular of at least two different fragrancing substances, relative to the total weight of the composition, and preferably at least three different fragrancing substances.
  • the composition contained in the reservoir comprises between 1% and 20% by weight of fragrancing substance(s), preferably between 5% and 17% by weight and even more preferentially between 10% and 15% by weight of fragrancing substance(s), relative to the total weight of the composition.
  • a subject of the invention is also a process for fragrancing human keratin materials, notably the skin, in which the composition is applied to said materials by means of the applicator pen according to the invention, as defined above.
  • the pen may be a disposable pen, i.e. once the reservoir is empty, it ceases to be used.
  • the pen is arranged to receive a refill containing the composition.

  • the fragranced composition is dispensed by means of a packaging and application device 1 which is in the form of an applicator pen.
  • This device 1 includes a body 10 of elongated shape along a longitudinal axis X, which dresses the pen and houses a tubular part 18 of elongated shape, forming a reservoir 11, having a neck 12 at its distal end.
  • the tubular part 18 is, for example, made of thermoplastic material, for example a polyolefin, for example polypropylene (PP).

  • the ring 15 is applied onto the brush substantially at the distal end 24 of the cannula 17 as illustrated in figure 2.
  • the bristles of the brush can thus be gripped between the ring 15 and the cannula 17.
  • the cannula 17 emerges, for example, at a distance w from the distal end of the application member, which represents between 1/3 and 2/3 of the total length L of the application member, namely the length of the bristles in the application under consideration.
  • L is, for example, between 15 mm and 25 mm, and is for example equal to 20 mm.
  • the cannula 17 may have a rotationally cylindrical portion l7a of length r between 0.5 and 1.5 cm, the inside diameter t of which is, for example, between 1 and 1.2 mm.
  • the length n of the application member 20 surrounded by the ring 15 is, for example, between 1/3 and 2/3 of the total length L, and is, for example, about 1 cm.
  • the device 1 may include a closing cap 30, arranged to be fixed onto the neck 12, for example by click-fastening, so as to obtain leaktight closure.
  • An actuating member 40 makes it possible to act on a mechanism 50 arranged to move the piston 13 in the direction of the outlet of the reservoir 11.
  • This mechanism 50 includes a driving shaft 51 which extends along the longitudinal axis X of the pen, attached to the piston 13 at its distal end 52.
  • This shaft 51 is externally threaded, has a flattened cross section, as shown in figure 3, and has two diametrically opposite grooves 54, emerging on the threaded surface.

  • the bearing part 80 fits into the distal part of the transmission part 71, as may be seen in figure 1.
  • the bearing part 80 has internal ribs 83 which are engaged in the grooves 54 of the shaft 51. Thus, the bearing part 80 can move along the shaft 51 without turning relative thereto.
  • the transmission part 70, the bearing part 80 and the retainer 90 have cooperating reliefs to transform a bearing on the actuating member 40 into a rotation of the shaft 51 by a certain angle, which is accompanied by a corresponding forward movement of the piston 13.

  • an essential oil is an odorous product, generally of complex composition, obtained from a botanically defined plant starting material, either by steam distillation, or by dry distillation, or by an appropriate mechanical process without heating (cold pressing).
  • the essential oil is usually separated from the aqueous phase via a physical process that does not result in any significant change in the composition.
  • the choice of the method for obtaining essential oils depends mainly on the starting material: its original state and its characteristics, its intrinsic nature.
  • The“essential oil/plant starting material” yield may be extremely variable depending on the plants: 15 ppm to more than 20%. This choice determines the characteristics of the essential oil, in particular viscosity, colour, solubility, volatility, and richness or poorness in certain constituents.
  • Steam distillation corresponds to vaporization, in the presence of steam, of a substance with low water miscibility.
  • the raw material is placed in contact with boiling water or steam in an alambic.

  • the aqueous distillate that remains after the steam distillation, once the separation of the essential oil has been performed, is known as the“aromatic water” or“hydrolate” or“distilled floral water”.
  • Production by dry distillation consists in obtaining the essential oil by distillation of woods, barks or roots, without addition of water or steam, in a closed chamber designed so that the liquid is recovered at the bottom.
  • Cade oil is the best known example of a product obtained in this way.
  • the method of production by cold pressing applies only to citrus fruits (Citrus spp.) via mechanical processes at room temperature.

  • the majority of industrial installations allow simultaneous or sequential recovery of the fruit juices and of the essential oil.
  • Essential oils are generally volatile and liquid at room temperature, which distinguishes them from“set” oils.
