Definitions

  • the present invention relates to the applying and dispensing of liquid cosmetic products.
  • cosmetic products is understood to mean any composition as defined in Regulation (EC) No 1223/2009 of the European Parliament and Council of 30 November 2009 relating to cosmetic products.
  • the present invention relates to the applying and dispensing of liquid cosmetic products for which it is recommended that only a small quantity of product be applied, for example a few drops (generally between two and five to six drops of product), if appropriate in a very localized manner.
  • compositions such as cosmetic oils or active cosmetic products.
  • active cosmetic products include, among others, certain healthcare products and acne and/or spot treatments.
  • the recommended application quantity for cosmetic oils is generally less than 0.1 ml.
  • the recommended quantity is approximately 0.5 ml.
  • Pipette systems and pump systems may be mentioned, for example.
  • a pipette can traditionally contain between 0.3 and 1 ml of product. Such a volume greatly exceeds the quantity of product that is recommended or necessary for application. The consumer therefore has to concentrate on not pressing too hard on the pipette, since pressing too hard would deliver more product than is necessary or recommended for application.
  • a spray pump diffuses the product in the form of droplets. Depending on the diffuser chosen, it is thus possible to diffuse only a small quantity of product. However, it is difficult to spray in a localized manner, and it is not uncommon for the spray to be applied outside the desired zone. Thus, product can spread as far as the ground and/or onto clothing, for example. In the case of greasy products, such as cosmetic oils, it is dangerous if the product ends up on the ground, since the lost product can make the ground slippery.
  • dispensing in the form of a spray is not suitable for all products. It is thus difficult to spray viscous products.
  • a cream pump permits localized dispensing. However, the quantity dispensed is still too great, since such pumps dispense at least between 140 and 250 ⁇ .
  • the document EP 0 872 193 proposes such a device. More precisely, the document EP 0 872 193 proposes a device comprising a foam applicator immersed permanently in the cosmetic product. The applicator becomes charged with product by capillarity during a pumping phase by decompression of the foam, and it releases the product again by exerting a pressure on the surface to be treated. For this reason, there is a not inconsiderable risk of the product running.
  • the quantity of product applied depends on the consumer and on the pressure exerted by the latter on the applicator. This applied quantity is therefore still difficult to control.
  • the document EP 0 872 193 envisions the use of a foam having relatively large cells capable of storing, and therefore delivering, a considerable quantity of product.
  • the present invention aims to achieve these objects and, for this purpose, proposes a device for dispensing and applying a liquid cosmetic product, comprising, on the one hand, a body which forms a reservoir and is equipped with a removable closure member and, on the other hand, an applicator, said applicator being movable between a first position, called the collecting position, in which the application member is situated inside the reservoir and is able to be at least partially brought into contact with a product to be contained in the reservoir, and a position called the application position, in which the application member can be brought into contact with a part of the human body, the device being characterized in that the applicator comprises at least one application member (8, 80) mounted on at least one grip member, characterized in that the application member has at least one application surface made from at least one non-compressible porous material with open cells.
  • Non-compressible material is understood as a material that does not experience any major deformation when a pressure is applied. More precisely, it is understood as a material which, unlike a sponge, a non-compressed foam or a felt, does not become charged with and does not discharge a product by pumping (compression/relaxation of the applicator).
  • non-compressible materials particularly suitable for an applicator according to the present application have a 25% compression strength of greater than 40 kPa, preferably of greater than 50 kPa, more preferably of greater than 150 kPa, or even 300 kPa.
  • the compression strength will be able to be determined in particular according to the standards DIN 53577 / ISO 3386.
  • the application member has a liquid product retention capacity which, in contrast to a compressible material, is invariable and does not depend on the pressure exerted by the user.
  • the release of the product is brought about by the application surface being placed in contact on the surface of the human body to be treated. This contact causes a rupture of capillarity at the level of the pores retaining the product and permits a transfer of the product onto the surface of the human body to be treated.
  • the proposed application member is non-mechanical and has no movable parts. It is therefore simple, economical and reliable.
  • the quantity of product that is collected and applied can be adjusted, in particular, according to the quantity of porous material used, its pore volume and/or the size of the pores of said material.
  • the non-compressible porous material is at least one material chosen from among sintered materials, in particular sintered plastics, for example polyethylene, ceramics, for example tile and/or brick, heat-compressed foams, for example polyethylene or polyurethane foams, pumice stone, wood.
  • sintered materials for example sintered plastics, for example polyethylene, ceramics, for example tile and/or brick, heat-compressed foams, for example polyethylene or polyurethane foams, pumice stone, wood.
  • sintered plastics for example polyethylene, ceramics, for example tile and/or brick
  • heat-compressed foams for example polyethylene or polyurethane foams, pumice stone, wood.
  • Such materials, in particular the sintered materials and the plastics are relatively easy to shape and are economical. Their porosity is also easy to control.
  • the porous surface has an average pore size of more than 30 ⁇ . More preferably, the porous surface has an average pore size of less than 70 ⁇ . Such a pore size permits good retention of the product while permitting its release upon contact.
  • the pore volume of the material is more than 35%.
  • the application member has at least one hollow, situated in particular at a free end of said application member, said hollow being able to retain, by capillarity, a quantity of product greater than the volume of one drop, preferably greater than the volume of six to eight drops.
  • a hollow of this kind permits localized dispensing of the drop-by-drop type, without the need for extensive applicative contact and in particular without the need to spread the application member across the surface to be treated.
  • the applicator comprises a product collection member, for example a pipette, in fluidic communication with the application surface via the porous material.
  • a product collection member for example a pipette
  • the quantity of charged product may be greater.
  • the collection member makes it possible to dispense larger drops.
  • the porous material serves as a filter and ensures a limitation of the rate of dispensing.
  • the grip member is a stem, in particular a plastic stem. More preferably, the stem is a hollow stem.
  • the hollow stem forms a pipette.
  • the application member has one or more peripheral reliefs.
  • the presence of reliefs confers a massage function on the applicator. Massage can also help the product penetrate the skin.
  • the reliefs can be peripheral and/or longitudinal, continuous and/or punctiform, distributed uniformly or non-uniformly depending on the desired massage effect.
