Definitions
- the present invention relates to a method for manufacturing a fluid product applicator comprising an outer shell defining an external application surface formed by an upper wall and intended to be placed in contact with an application surface, this outer shell defining an internal cavity delimited by a side wall capped by the upper wall, the internal cavity communicating with the external application surface through at least one through hole formed by the upper wall, the fluid applicator also comprising a piece of porous material defining an internal network of open cells through which the fluid product can pass, the piece of porous material being disposed in said internal cavity.
- the preferred fields of application of the present invention are those of perfumery, cosmetics or even pharmacy.
- US5199808 is already known which describes applicators of this type, implementing a foam placed in a cavity whose wall forms a perforated application surface. More specifically, it is an annular piece or a foam layer which is disposed in a cavity whose perforated application wall is flexible.
- This type of foam piece has a triple disadvantage, namely that the mold must be previously molded, manipulate and dispose in the cavity and hold in place in this cavity. In addition, it is inevitable that the fluid returns to the application wall passing on the periphery of the foam part bypassing it, not through. Finally, it is difficult in this configuration to obtain a mechanical locking undercut of the foam part and the cavity.
- the present invention proposes a method of manufacture in which the internal network of open cells of the piece of porous material is directly made inside the internal cavity, which thus serves as a training receptacle for the piece of material. material porous.
- the piece of porous material is created in the outer shell. This ensures an intimate contact between the piece of porous material and the outer shell, avoiding peripheral leakage. Handling and editing procedures are eliminated. Mechanical hooks are easily achievable.
- the piece of porous material may be a sintered part which is directly sintered inside the internal cavity of the outer shell.
- the outer shell and the porous material are chemically compatible, so that a chemical bond is created between them. And when the outer shell and the porous material are chemically incompatible, the porous piece and the outer shell form mechanical latching profiles to hold the porous piece in the internal cavity.
- Peripheral leakage problems are frequently encountered with rigid porous materials, such as Porex®, because their contour is irregular and thus create open cells of dimensions greater than that of the internal network. With the method of the present invention, these open-edge cells are removed. The sintering process can even be controlled so that the sintered particles or balls merge with the inner wall of the cavity or collide against it. Sufficient dress is created.
- the piece of porous material at least partially fills said at least one through hole. It is thus possible to provide that the piece of porous material comes flush with the outer surface of application. It can even protrude beyond the external surface of application to confer a relief structure, which can promote a massage action or peeling.
- the outer shell may be externally temperature controlled during sintering of the porous material in the internal cavity, in particular to not deform or deteriorate.
- the piece of porous material may also be a foam obtained from a liquid foam, which is expanded and then solidified, inside the internal cavity.
- the method may provide for removing the projecting parts. This can be particularly beneficial with foams that form on the surface a tough, watertight skin that must be removed to open the internal network of open cells. The protruding portions can simply be leveled or eroded.
- the spirit of the invention lies in creating an array of open cells directly inside the outer shell which thus serves as a crucible or formation vessel. Sintering is the preferred method, but foaming is also possible.
- FIG. 1 is a vertical cross-sectional view through a fluid dispenser made according to a first embodiment of the invention
- FIG. 3 is a top view of the applicator A1 of FIG. 2; and
- FIGS. 4 to 7b are schematic views in vertical cross section illustrating FIG. four other embodiments of the present invention.
- the fluid dispenser as shown in Figure 1, comprises a fluid reservoir R with which is associated a fluid applicator A1.
- the tank R may be made of any suitable material and have any aesthetic and / or functional form.
- the tank R may have an elongated and thin configuration so as to give the dispenser a general configuration of a pen.
- the tank R of Figure 1 may for example be made of drawn glass. It is advantageously transparent. It contains a fluid product, preferably of low viscosity, such as perfume, serum, makeup ink, a liquid foundation, an oil.
- the viscosity of the fluid product F is of the order of a few centipoises or tens of centipoises, generally less than 100 centipoises.
- the tank R defines a collar R1 on which the fluid applicator A1 is fixedly mounted and sealingly.
- the fluid product applicator A1 comprises an outer shell 1, a piece of porous material 2 and optionally a protective cover 3. According to the invention, the piece of porous material 2 is directly made or molded inside the shell external 1.
- the outer shell 1 defines an inner cavity 10 which is here completely filled by the piece of porous material 2. It is also conceivable that the internal cavity 10 is not completely filled by the piece of 2. More specifically, the outer shell 1 comprises a side wall January 1, which here is substantially or perfectly cylindrical. This side wall January 1 is capped at its upper end by an upper wall 12 which is traversed by several holes of passages 14, which are more clearly visible in Figure 3.
- the outer surface of the application wall 12 defines a surface of application 13 which is intended to be placed in contact with an application surface, such as skin, nails or hair. It can thus be said that the external application surface 13 communicates directly with the internal cavity 10 through the through-holes 14. Referring to FIG. 3, it can be seen that the application wall 12 comprises five through-holes.
- the application surface 13 is formed between and around these through holes 14.
- the side wall joins an annular flange 15 which forms a central opening 151.
- the internal cavity 10 is delimited by the side wall January 1, the application wall 12 and the annular flange 15.
- the piece of porous material 2 extends inside the holes of passage 14 up to flush with the external application surface 13.
- the piece of porous material 2 does not extend inside the central opening 151 of the annular flange 15.
- the piece of porous material 2 does not extend inside the through holes 14, or at least not entirely.
- the outer shell 1 forms a sleeve 16 which defines two outer shoulders 18 and 19 and a fixing skirt 17 which cooperates with the neck R1 of the fluid reservoir R. It can thus be said that the interior of the tank R communicates with the internal cavity 10 through the neck R1, the sleeve 16 and the central opening 151 of the flange 15. It is not excluded to provide a valve at the neck R1, the sleeve 16 or the central opening 151.
- the piece of porous material 2 is a sintered part which is directly sintered inside the internal cavity 10.
- the sintering is obtained not a mass of fusible particles or balls which are subjected to a sufficiently high temperature to melt the surface particles or beads so as to fuse them together, thereby creating an internal network of open cells.
- the present invention recommends instead to partially or completely fill the internal cavity 10 particles or fusible beads, then sintering directly inside the internal cavity 10.
- the sintering of the particles or balls inside the internal cavity 10 makes it possible to create an intimate contact with the inner wall of the internal cavity 10.
- the piece of sintered porous material 2 can thus fill or not, or even partially, the internal cavity 10, the through holes 14 and / or the central opening 151. If a chemical bond is not possible between the sintered part and the outer shell 1, the annular flange 15, as well as the penetration of the parts 24 of the sintered part in the through holes 14, form mechanical attachment profiles that keep the sintered part 2 perfectly stable inside the internal cavity 10. Without leaving the frame of the it is also conceivable to form a part of the piece of porous material 2 inside the sleeve 16 through the central opening 151. Part of the piece of porous material 2 can even penetrate inside the neck R1.
- a sintered part it is also possible to implement a foam obtained from a liquid foam, which is expanded and then solidified, inside the internal cavity 10.
- the expansion of the liquid foam is done directly inside the internal cavity 10 and generates in situ the internal network of open cells. Again, a chemical bond or not is possible.
- Other types of porous materials may also be used in the context of the present invention.
- the outer surface of the shell forming the cavity 10 may for example be cooled, tempered or even heated, as the case may be.
- FIG. 4 a very schematic view of an applicator A2 whose outer shell 1 is summed up to a cap comprising a side wall 11 open downwards and closed at its upper end by a application wall 12a pierced by several through holes 14a.
- the outer surface of the wall 12a forms an application surface 13a.
- the piece of porous material 2a which can be sintered or foamed, occupies only the internal cavity 10, excluding the through holes 14a.
- This piece of porous material 2a can be held inside the outer shell 1a, for example because a chemical bond has been made between the piece of porous material 2a and the outer shell 1a. Indeed, we see in Figure 4 that there is no hanging profile to retain the piece of porous material 2a inside the shell 1 a.
- the fluid product applicator A3 comprises an outer shell 1b comprising a side wall 1 1b forming internally a fastening profile 1 12.
- the application wall 12b is pierced with a single through hole 14b which is filled by a portion 24b of the piece of porous material 2b. It can be specified that the portion 24b comes flush with the application surface 13b.
- the piece of porous material 2b need not be chemically bonded with the outer shell 1b, because it can simply be kept inside the internal cavity 10 by the attachment profile 1 12
- the portion 24b can also promote or complete the mechanical attachment of the piece of porous material 2b in the outer shell 1b.
- the fluid product applicator A4 comprises an outer shell 1c, which may advantageously be made of a resilient flexible material, which may in particular be easily deformed by crushing.
- This shell 1c comprises a side wall 11c which is closed at its upper end by an application wall 12c pierced with a plurality of through holes which are partially filled by the piece of porous material 2c. It can be seen in particular that parts 24c of the piece of porous material 2c partially fill the through holes 14c. Thus, the piece of porous material 2c remains set back from the application surface 13c.
- the outer shell is made of a crushable flexible material, it is possible to bring the parts 24c into contact with the application surface (skin, nails, hair) by depressing or crushing the application wall. 13c.
- the piece of porous material 2c can be held inside the internal cavity 10 by a chemical bond, or by mechanical attachment means (not shown).
- FIGS. 7a and 7b describe a last embodiment of the invention, in which the piece of porous material 2d is a foam, obtained by expansion of a liquid foam, then solidification.
- the piece of porous material 2d is a foam, obtained by expansion of a liquid foam, then solidification.
- an outer shell 1 d comprising a side wall 1 1 d and an application wall 12d pierced by through holes.
- Liquid foam was deposited inside the outer shell 1 d, before it expands, then solidifies.
- Figure 7a shows the result after expansion and solidification.
- the foam 2 'd completely fills the internal cavity 10 and the through holes, and projects outwardly beyond the application surface 13d at 25. Similarly, the foam projects below the outer shell 1 d in 26.
- Some foamed foams have the property of forming a tight and resistant outer skin which closes the internal network of open cells.
- this skin is formed on the surface of parts 25 and 26 of Figure 7a.
- these projections 25 and 26 are removed, for example by shaving or abrasion, so as to achieve a fluid product applicator A5 as shown in Figure 7b. It can be seen that the portions 24d are now located flush with the application surface 13d and that the piece of porous material 2d no longer protrudes out of the outer shell 1d at its lower end. By this operation of removing the protruding parts 25 and 26, the internal network of open cells is again open to the outside, so that a fluid product can pass through.
- the outer shell can be made by plastic injection or metal stamping. It can even be made of glass or ceramic.
- the application wall can confer a cold effect on contact with the skin. Its thickness can range from a few tenths of a millimeter to several millimeters.
- the wall of the inner cavity may be treated or coated with a film or a layer to improve the adhesion of the piece of porous material in the cavity.
- Passage holes may represent a particular logo or pattern. In some cases, the through holes will define a cumulative passage section that may be greater than the application surface of the shell application wall defined between and around the through holes.
- the cumulative area the piece of porous material at the passage holes may be greater than the application surface defined by the shell around the through holes. In other cases, the holes will define a cumulative passage section smaller than the application surface.
- Solidified expanded foam can be used in place of a sintered part.
- the outer shell 1 may be rigid, transparent, opaque, deformable, crushable.
- the piece of porous material can penetrate partially or completely inside the passage holes, or not at all. It can even protrude beyond the application surface 13c to come into contact with the application surface, for example to impart a massaging or abrasive effect.
- a soft foam will provide a soft contact, while a sintered piece, for example of the Porex® type, will confer an abrasive effect.
- a fluid product applicator is obtained, the piece of porous material intimately or even adhering to the inner wall of the internal cavity of the outer shell.
