  • the invention is particularly intended the packaging and application of cosmetic products such as bottoms liquid foundation, nail polish, lipstick, oil possibly gelled, creams, lotions, hair treatments, etc.
  • Applications in fields other than cosmetics can be also envisaged, in particular in the field of dermopharmacy or in the fields of glues, writing correctors, stain removers household products, etc.
  • Liquid products, the viscosity of which is between that of water and an oil or even a gel or gel lotion are particularly adapted to be dispensed according to the present invention.

  • the applicator pad being confined in the upper part of the neck. Loading product of it requires to return it and pressing its application surface several times on the support to be treated in order to "pump” and load it with product before applying it, pressure exerted on the applicator, causing the opening of a valve which, in closed position, isolates the applicator from the product.
  • these applicators containing usually volatile formulas, often dry out quickly during the storage period causing the crust to form on the applicator.
  • the applicator pad is isolated from the product by means of a valve, which further accelerates the drying of the applicator, the sometimes rendering it unusable after a long period of non-use, or requiring cleaning operations prior to any new use.
  • applicators in the form of a block of foam that we soak in the product to be applied then, after wringing, either on the neck of the bottle, either through an elastic wringer, which is applied to the support to be treated.
  • the applicator is generally secured to the stopper.
  • the dosage of the product to applying by impregnating the applicator is difficult to adjust from product to product the other, depending on the variable rheology of the products.
  • its use remains delicate in certain circumstances, in public transport for example, due to the independent nature of the applicator and the reservoir, which implies in these conditions of use to hold the container upright in a hand, and proceed with the application of the product with the other.

  • the application surface is axially movable between a first position in which the application surface emerges outside the neck at across said opening, for application of the product, and a second position in which said application surface is contained inside the tank. Moving from the first position to the second position of the application surface is effected by an elastic push against a sealing means, a displacement of the application surface of the second position towards the first being effected by removal of said plugging means.
  • the Applicant has found that certain materials forming the organ deteriorate, especially when exposed during period extended at said elastic thrust.

  • the application member is crossed by at least one passage, in particular in the form of one or more slots, or of a fine channel, opening out preferably on the application surface, so as to increase the capacity of dosage and flow rate of the product.
  • these can be arranged in a cross or star shape.
  • the applicator member and the support means are arranged inside a housing, partly formed inside a neck of the tank, said housing being in communication with the tank.
  • this housing is cylindrical or frustoconical, in particular flared towards outside. It can have, for example, a circular cross section, oval, rectangular or polygonal.
  • the housing is separated from the tank by through a perforated element, in particular in the form of a grid, a screen or unidirectional opening valve towards the surface of application.

  • the removable closure means may have an internal profile capable of sealing with the open end housing, said internal profile may also have a shape complementary to the shape of the application surface. So we can get a support regularly distributed over the entire application surface with a homogeneous compression of the material constituting it. During the expansion of the foam of the applicator member, there is a uniform pumping of product by the expanding foam cells. When supporting the organ of application on the support to be treated, this results in a homogeneous release of the product.
  • the sealing means comprise a element, in particular in the form of a suitable foam block, in the closed position of the reservoir, to come into engagement with the application surface.
  • This block of foam can be deformable, and can be impregnated with a suitable solvent or a conservation officer.
  • the support of said block of foam on the applicator member is carried out gently. This avoids that the application surface, especially when it is fragile, is not damaged, which may be the case when it is covered with a coating of flocking.
  • the presence of a solvent in the foam prevents drying of the product on the application surface. Presence of a preservative in the foam prevents the development of microorganisms on the surface of application or degradation by oxidation of the product.

  • at least one axial slot 33 passes through the applicator member 10, from the top of cone 17'e towards the application surface 15. The width of this slot may vary depending on the rheological properties of the product and the desired flow rate.
  • the structure of the nozzle 60 is such that the surface of the cross section of the support means 17 'is less than the cross-sectional area of the application body 10.
  • FIG. 10b illustrates a tip 62 different from the embodiment of the tip 60 shown in Figure 10a. It differs from the embodiment of FIG. 10a by the fact that the support means consist of a single part 17, comprising, in addition to the conical recess 17c, a large external annular groove 17d, so that the cross-section of the support means 17 'is significantly less than the cross-sectional area of the organ of application 10.
  • This structure gives tip 62 similar properties to the properties of the nozzle 60 of FIG. 10a.
  • FIG. 10c illustrates a tip 64 of construction similar to the construction of the tip 62 shown in FIG. 10b. It differs from the realization of the figure 10b by the fact that the support means consist of a portion frustoconical 17, the section of which decreases in the direction of the reservoir. A portion end 17f forms a heel, fixed on an openwork plate 13b provided with a multitude of passages 13a. Similar to the embodiment of Figures 4a and 4b, the perforated plate 13b is integral with a base 17a, mounted on the part lower 4b of the housing 11.
  • FIG. 10d illustrates a tip 66 similar to the embodiment of the tip 62 illustrated in FIG. 10b, shown in the storage position (in solid lines) and in the position of use (discontinuous line). It is essentially distinguished from the realization in FIG. 10b by the fact that the housing 11 has a frustoconical shape, flared outwards. We see that the compression of the part forming the organ application 10, under the effect of the compression exerted by the profile 19 of the plug 5, causes in the storage position, a tight contact between the internal wall of the housing 11 and the periphery of the application member 10.
  • FIG. 10e illustrates an end piece 68 similar to the embodiment of the end piece 66 of the Figure 10d, shown in the use position. It differs from the structure of the tip 66 described above, by the fact that the part forming the support means 17 is ends, on the tank side, with a wide heel 17f, this part being separated by an area of smaller cross section 17th of the part forming the member of application 10.

  • a wide throat annular 17th defines an area of least cross section, compressibility less than the compressibility of the applicator member 10.
  • the tip 72 shown in Figure 11b, is distinguished from the tip 71 of Figure 11a by the fact that it has an axial slot 33, making it possible to increase the flow rate of product, especially a gelled product or a viscous product.

So we can give the whole more softness during application.
  • the end piece 74 differs from the end piece 73 in FIG. 11c by the fact that the recess 17c is extended by a slot 33 leading to the application surface 15. This arrangement makes it possible to impart more softness during of the application, while increasing the product flow during the application.
