Definitions

  • the present invention relates to a device for packaging and applying a cosmetic product to keratin materials, in particular to keratin fibers, notably the eyelashes and/or eyebrows and/or hair fibers.
  • a device of the“dip in” type comprising an applicator having a stem provided at one end with an application element that generally forms a brush or comb, and at the other end with a gripping part forming a closure member for closing a container of the device that contains the cosmetic product to be applied.
  • the application element soaks in the cosmetic product.
  • the applicator is separated from the container to allow the makeup to be applied.
  • Another, less common, type of device can be used to apply a cosmetic product, the application element then being permanently secured to the container, being supplied with product through the opening of the container.
  • a closure member covers the application element in order to close the container when it is not in use.
  • a device of this type is known from FR 2 956 332 or EP 2 361 846, which describe a device for applying a fluid, comprising a body surmounted by a head and a foam applicator mounted on a holder, the applicator and the holder being mounted on the head of the body.
  • This type of device is also the subject of FR 2 864 431, which describes a dispenser for a fluid cosmetic product, comprising a container surmounted by an application head that is supplied with product with the aid of a piston.
  • EP 0 513 197 discloses a unit dose of product in a tube closed by a wall and surmounted by a cap that itself comprises an applicator and perforation means. When the cap is pushed toward the container, the perforation means pierce the wall and allow the product to be dispensed through the applicator.
  • EP 1 293 448 relates to an X-axis assembly for the packaging and application of a cosmetic product, comprising a first compartment forming a reservoir containing said cosmetic product, and a second compartment, in selective or permanent communication, with the first via at least one orifice, and intended to receive an applicator member of said product, the applicator member being for example a block of foam with open cells, a closure element being able to close an opening delimited by an edge of said second compartment, the first compartment being of variable volume, the second compartment being of fixed volume, the axial height H of the assembly being able to decrease with the volume of the first compartment.
  • EP 0 872 193 discloses an assembly consisting of a container for the product, with an aperture closed and sealed by a cap, and an applicator which has one end in constant contact with the fluid and its other end forming an applicating tip.
  • the applicator is made from an absorbent material with open cells and is at least partially compressed inside the container.
  • the applicator is made at least partly from a foam material such as polyurethane, polyethylene, PVC, polyether, polyester, or natural or synthetic rubber and can also be made partly from a fritted material such as PVC, ethylene vinyl acetate or felt.
  • US 8 226 318 describes a cosmetic product dispenser comprising a container body provided with a neck designed to engage with a cap, the container being surmounted by an applicator.
  • a central duct passes through the applicator and allows the latter to be supplied with product during use.
  • the cap is provided on the inside with a protruding relief that engages in a sealed manner, when it is in place on the container, with the central duct.
  • One difficulty with devices of the“go through” type compared with devices of the“dip in” type is that the applicators of the former can dry out when not in use, the device being closed, whereas the applicators of the latter are always in contact with the fluid product contained in the container when the device is closed, and are therefore not subject to as much drying out.
  • the present invention aims to meet these needs and the subject thereof is a device for packaging and applying a cosmetic product to keratin materials, the device extending along a longitudinal axis and having:
  • an application element for applying the product which is carried by the container and surmounts the opening of the container, the application element comprising a compressible foam that at least partially defines an application surface of the application element, said application surface being longer than it is wide with respect to the longitudinal axis of the device,
  • a closure member for closing the container which is designed to cover the application element in a closed position of the device, the application surface being supplied with product in an open position of the device, the foam then being in an expanded state
  • the closure member being configured to radially compress the foam when the closure member is fitted over the application element during the closure of the device and/or when the closure member is in place over the application element in the closed position of the device.
  • the application element is elongate along the longitudinal axis of the device.
  • a device of the “go through” type is provided, limiting the risk of drying out of the product. For example, it is possible for a large part of the product present on the application element when the product is applied, in the open position of the device, to be driven into the container by the compression of the foam forming the application element during the closure of the device. It is also possible to reduce the volume of air present in the environment of the application element.
  • the product not to be able to pass through the application element during the closure of the device.
  • the greatest length of the application surface may be between 12 mm and 27 mm.
  • the greatest width of the application surface which may be a diameter, may be between 6 mm and 10 mm.
  • the closure member is configured to radially compress the foam only when the closure member is fitted over the application element during the closure of the device.
  • the foam is advantageously not compressed radially or axially, or is only partially compressed radially or axially, notably along less than a quarter of its length, when the closure member is in place on the container.
  • the closure member is configured to also radially compress the foam when the closure member is in place over the application element in the closed position of the device.
  • the foam may in particular be compressed along at least a quarter, better still a third, even better still half or even all of its length when the closure member is in place on the container. The foam may thus be compressed radially and optionally axially.
  • the closure member has a wiping member that protrudes radially toward the inside and is configured to partially compress the foam at least as it passes through the wiping member during closure.
  • the wiping member is preferably made of an elastically deformable material, for example an elastomer.
  • the closure member and/or the wiping member may have a plurality of fins that are configured to press against the foam and constrain it, preferably elastically deformable fins, which are notably able to bend in the axial direction.
  • the fins may extend along a portion of between 1% and 10% of the length of the closure member.
  • the wiping member may have at least one wiping lip, which may make it possible to constrain the foam around its entire periphery.
  • the fins may extend along at least a quarter, better still a third, even better still half or even all of the length of the closure member.
  • the closure member may have an inner surface that does not have any reliefs protruding toward the inside for compressing the foam.
  • the inner surface is then substantially smooth.
  • the dimensions of the foam and those of an inner surface of the closure member may be provided so as to allow the compression of the foam when the closure member is fitted in the closed position of the device.
  • the internal cross section of the closure member may be less than the external cross section of the foam.
  • the closure member may thus be configured to radially compress the foam when the closure member is in place over the application element, in the closed position of the device, the foam then preferably being in a sufficiently compressed state to prevent the passage of the product, notably with respect to flow under gravity if the container is turned over.
  • the device has for example a core having at least one opening for the product to pass through, the core being fastened to the container and passing through the application element along at least a part of its length.
  • the application element may be fastened to the core, the latter being fastened to the container at the opening of the container and thus making the connection between the application element and the container.
  • the core may have a plurality of lateral openings for the product to pass through.
  • the core may be hollow along at least a part of its length in order to form a duct for the product to pass through.
  • the core may be entirely surrounded in cross section by the foam.
  • the applicator may constitute a brush.
  • the foam may also partially surround the core, over an angular extent, measured around the longitudinal axis of the core, of between 90° and 240°, better still between 120° and 200°.
  • the applicator may constitute a comb, the core then forming a holder for the foam.
  • the foam may be fastened to the core in various ways.
  • the foam is fastened to the core by welding, notably by ultrasonic welding, by adhesive bonding and/or with the aid of at least one retaining relief.
  • the container may be made of a flexible material such that, by exerting a pressure thereon, the user can cause the product to exit through the opening of the container as far as the application surface of the application member.
  • the container may be equipped, notably at the opposite axial end from the end provided with the application element, with a button for actuating a pump or, better still, with a mechanism for advancing a piston which makes it possible to force the product forward toward the application element.
  • the user actuates the button, for example by translation or rotation, causing the application surface to be loaded with product.
  • the core may be made of a rigid or semirigid plastics material that is harder than the foam.
  • the foam is advantageously an open-pore polymer foam, chosen preferably from foams made of crosslinked polymer, notably foams made of crosslinked thermoplastic polymer, in particular crosslinked polyurethane, crosslinked polyester, crosslinked polyether or crosslinked polyethylene.
  • a polymer foam should be understood as being a cellular material made from a polymer and constituted by a three-dimensional structure formed by a solid skeleton comprising solid walls and/or solid ridges, surrounding cells, with spatially random orientations.
  • the porosity which is all of the voids created by the pores, or cells, exceeds 70% of the total volume of the foam.
  • An“open-pore polymer foam” is understood to mean that the cells of this material are open to the adjacent cells and to the outside. In this case, it is only the ridges surrounding the cells that form the solid skeleton of the foam. There are no solid walls.
  • the shape of the cells may be spherical or polyhedral.
  • the open-pore polymer foam allows fluids to pass through when it is in the expanded, i.e. noncompressed, state. By contrast, when it is sufficiently compressed, the open-pore polymer foam does not allow fluids to pass through.
  • the product passes through the foam and supplies the application surface with product.
  • the foam can be compressed during closure or when the device is in the closed position, sufficiently so to prevent the product from passing through, thereby making it possible to avoid any drying out of the product.
  • the number of cells per unit length characterizes the polymer foam. It corresponds to the number of pores, or cells, intercepted in a length of 1 inch (2.54 cm).
  • the foam preferably has a number of cells per unit length (PPI) of between 10 and 80 PPI, better still between 20 and 50 PPI, even better still equal to around 30 PPI.
  • 10 PPI thus corresponds to 10 cells per inch, i.e. to 10 cells per 2.54 cm.
  • Figure 4 illustrates six foams disposed one after another, along the ruler, exhibiting different PPI values of 8, 10, 15, 20, 25 and 30 PPI respectively, with the PPI value increasing down the figure.
  • the foam may moreover have a density of between 10 kg/m 3 and 60 kg/m 3 , better still between 20 kg/m and 40 kg/m , even better still equal to around 30 kg/m .
  • Such ranges of the number of foam cells per unit length (PPI) and/or foam densities are particularly advantageous in the context of use of the application element according to the invention for applying a cosmetic product such as a mascara composition or a coloring product and/or a care product for hair fibers.
  • the foam may have, on the application surface, free strands formed by all or some ridges of cells cut by machining the foam.
  • the ends formed by the free strands allow the eyelashes, eyebrows and/or hair fibers to be combed, separated and/or lengthened gently. This makes it possible to avoid damaging and/or pulling out the eyelashes, eyebrows and/or hair fibers, while at the same time obtaining a result that is satisfactory in terms of combing, separation and opening out of the eyelashes in particular.
  • the length of the free strands may be between around 0.1 mm and 4 mm, preferably between 0.5 mm and 2 mm. It should be noted that, for one and the same application element, the length of the free strands will not generally be constant, given that they are obtained by machining the foam.
  • Some strands will be short, for example with a length equal to around 0.1 mm, while other strands will be longer, up to a length equal to the length of a cell ridge of the foam, for example 4 mm.
  • the mean length of the free strands may be between 0.5 mm and 2 mm.
  • the foam is, for example, machined by stamping-out, laser, milling and/or waterjet cutting. Machining by milling is preferred, since such a machining method makes it possible to easily produce an application element having an envelope surface of complex shape.
  • the machining of the foam makes it possible to create, on the outer surface of the foam, the free strands which will comb the eyelashes, eyebrows and/or hair fibers.
  • the cells of the foam will, for their part, make it possible to constitute reserves of product in the immediate vicinity of the combing strands.
  • the product is advantageously a mascara for the eyelashes or eyebrows.
  • a mascara composition conventionally has a viscosity at 25°C of greater than 5 Pa.s, notably between 5 Pa.s and 50 Pa.s, in particular measured with the aid of a Rheomat RM100® machine.
  • Such a mascara composition conventionally comprises a solids content, generally in an amount greater than or equal to 35% by weight relative to the total weight of the composition, a pulverulent colorant, in particular one or more pigments, notably one or more metal oxides, for example one or more iron oxides, and advantageously a film forming polymer.
  • a mascara composition may also conventionally comprise one or more waxes, in a total amount of in particular between 5 and 40% by weight relative to the total weight of the composition.
  • the ranges proposed above for the number of foam cells per unit length (PPI) and/or foam density make it possible to have an application element that demonstrates a good compromise between its capability to retain and to release a cosmetic product having a viscosity of between 5 Pa.s and 50 Pa.s, notably between 9 Pa.s and 25 Pa.s.
  • the product retention capability of an application element of a device according to the invention makes it possible in particular to prevent the cosmetic product held within the foam of the application element from flowing through the latter under gravity and thus to improve the cleanliness and autonomy of such an application element.
  • the retention of the cosmetic product within the foam of the application element is achieved in particular by surface tension of the product held inside the cells present in the foam.
  • the product-release capability of an application element of the device according to the invention makes it possible in particular for the product held within the foam of the application element to be loaded onto the eyelashes/eyebrows and/or the hair fibers when these are brought into contact with the application element.
  • the cosmetic product held within the foam of the application element is released in particular by the eyelashes, eyebrows and/or hair fibers being brought into contact with the cells of the foam, this contact breaking the surface tension that exists between the product and the cells of the foam, the product then being deposited on the eyelashes, eyebrows and/or hair fibers.
