The invention relates to a packaging and/or application device for cosmetic or care products having fibers containing particles capable of absorbing a liquid or a compound in a liquid solution or soluble in a liquid.

Description

Cosmetic or care product packaging and/or coating device and method for its fiber

technical field

The present invention relates to the application of a substance, in particular a cosmetic or care product, to the skin, hair or finger or toe nails. The cosmetic product is a known product as defined in Directive 93/95/CEE of Counsel of 14.06.1993.

In particular the invention relates to fibers for coating substances or fillers in substances.

Background technique

There is a need for fibers, in particular for the construction of brushes or flocks, which are capable of absorbing relatively large quantities of substances, for example in order to enable applicators to be used continuously for long periods of time.

There is also a need for a bristle for a mascara brush that is able to grip the eyelashes, for example, so that they can remove material from the surface of the eyelashes or bend them.

There is also a need to improve the preservation of cosmetic or care products.

There is also a need to be able to create new states of coated cosmetic or care products with fibers, which are suitable for producing new cosmetic effects.

Finally, there is a need to be able to reduce the drying rate of cosmetic or care products on the applicator, especially when the applicator is not quickly reinserted into its container or needs to be kept in a humid condition under the sealed cap .

Contents of the invention

The aim of the invention is in particular to fulfill all or some of these requirements.

The invention achieves this object by a packaging and/or application device for cosmetic or care products, characterized in that it comprises fibers containing microparticles capable of absorbing liquids or compounds in liquid solutions, Or can be dissolved in liquid.

In the present invention, the term "fiber" is used to denote any ordinary elongated body, such as bristles used to make up mascara brushes, bristles in flocked coatings, bristles in oil brushes, especially for Nail varnish or powder, or indeed the fibers used to make up the filler contained in the substance intended to be applied to the eyelashes, for example in order to lengthen them. The fibers may be relatively flexible, or indeed elastically deformable, and they may be made of synthetic material.

The above-mentioned liquids may be cosmetically acceptable, for example, water or oil or aqueous ethanol or oil solutions that can be applied to the human body, but are not limited to those listed.

The liquid may be contained in the coated product.

Therefore, the object of the present invention is a device for coating a product comprising:

A plurality of fibers for use in coated products, characterized in that at least one fiber comprises a plurality of shaped particles, at least one of which is capable of absorbing one of the following:

an amount of liquid having a weight equal to the weight of the particle; and

compounds in liquid solutions; and

dissolve in liquid. The plurality of particles can be free of cotton.

At least one of said fibers may have a substantially constant cross-section, for example formed by extrusion or coextrusion from one or more thermoplastic and/or elastomeric materials. The fibers can be coextruded from two synthetic materials, one of which is filled, for example, with the above-mentioned particles. The particles may be at least on the surface of at least a portion of the fibers, and may be only on the surface or optionally dispersed throughout the plastic material.

In a particular embodiment, the particles are adapted to increase in volume when in contact with the substance to be coated, for example they are capable of swelling when in contact with a solvent contained in the substance to be coated, such as water. Such volume increase can act to create surface asperities on the surface of the fiber which can form areas for holding substances, which is useful when the fiber is used for coating purposes and impregnated with a supplied cosmetic or care product. It is advantageous when in the container of the product.

The use of microparticles that absorb liquids and can swell on contact with liquids, or dissolve on contact with liquids, can serve to create specific anchoring areas on fibers used to coat cosmetic or care products, especially since the microparticles are The affinity of a hydrophilic or lipophilic compound contained in a substance. Thus, the substance can be better attached to the fibers and the applicator can carry a larger quantity of substance.

The presence of microparticles adapted to absorb liquids and optionally to swell when in contact with such liquids can also be used to delay drying of cosmetic or care products on the surface of the fibers, since when solvents such as water contained in cosmetic or care products Upon evaporation, the particles which have absorbed the liquid then release the liquid into the material surrounding the fiber. Delaying the drying of the substance on the surface of the applicator is advantageous because it not only enables the applicator to be used for a longer period of time, but also delays its drying when it is not in use and not immersed in the substance , for example when it is only protected by a protective cap.

The microparticles, which are for example crystalline when dry, may soften when in contact with a liquid contained in the coated product.

This makes the fibers softer after absorbing liquid. By selecting the nature of the particles and the amount added, the fiber has the desired softness.

The microparticles can absorb at least their weight in liquid, such as water.

Materials that can cause the particles to increase in volume when in contact with the substance to be coated, especially water, can be as follows, but this example is not meant to be limiting: Swelling in the presence of water or liquids Polymers; superabsorbent reticulated polyacrylates with a high coefficient of expansion in water; polyvinyl alcohol; carboxyvinyl polymers; semi-synthetics derived from cellulose; starch; Biogum; biosaccharides; scelro-dextran; casein; vegetable gums such as alginates, gelatins, gelanes, xanthan gum (Xanthan); synthetic hectorite; silica, especially colloidal silica; and the like mixture.

Superabsorbent materials can absorb at least two, ten, fifty or one hundred times their weight in liquid, for example polyacrylates can be used.

Prior to expansion, the microparticles may have a particle size, for example, in the range of 0.1 micrometer (μm) to 300 μm, or in the range of 5 micrometer (μm) to 200 μm, or in the range of 10 micrometer (μm) to 150 μm.

The particle size of these particles will be selected as a function of the desired roughness after expansion.

The dry weight concentration of the microparticles may range from 0 to 20%, preferably less than or equal to 6%, relative to the total weight of the fiber before expansion.

For the manufacture of the fibers, the material used may be chosen to expand, for example to enable a relative increase in volume of 15% when in contact with the substance to be coated.

The plastic material used to make at least one fiber can be selected from the following examples: polyamide; polyethylene terephthalate (PET); acetate, polyethylene (PE); polypropylene (PP); Vinyl chloride (PVC); amide block polyesters; plasticized ^Rilsan® ; elastomers, especially polyester elastomers, PE elastomers, silicone elastomers, nitrile elastomers; and mixtures of these materials.

In a particular embodiment, at least one of the fibers comprises particles adapted to be soluble on contact with a liquid, such as water. The microparticles can be water-soluble or fat-soluble. The dissolution of the particles renders surface roughness on the fibers, preferably even making the fibers porous. The primary particle size of these microparticles may range from 0.1 μm to 300 μm.

At least one of the fibers may comprise particles adapted to absorb liquids, such as water, with or without swelling. The advantage of using the microparticles is that it enables the delivery of one or more compounds into the fiber, for example in order to impart biocidal properties, especially bactericidal properties. In particular, the fibers may contain microparticles suitable for absorbing maintenance substances in liquid solutions, especially aqueous solutions.

The concentration of microparticles suitable for absorbing liquids or compounds in liquid solutions may be in the range of 0 to 20% by weight relative to the total weight of the fibers before the fibers come into contact with said liquid, or within 0 to 6% range.

The fiber can have many cross-sections, for example, its cross-sectional shape can be selected as follows: circular symmetry or asymmetry; circle; solid or hollow square; Solid or hollow star; U-shaped; V-shaped; I-shaped; T-shaped: Z-shaped; ---shaped; +-shaped; kidney-shaped; three-branched; hollow; or a combination of these shapes. The fibers can be twisted.

Packaging and coating equipment employing the fibers of the present invention may optionally include a wiper.

The fibers of the invention may belong to applicators suitable for absorbing substances, as described above.

The applicator may be a mascara brush, the at least one bristle of which brush consists of a fiber according to the invention.

As mentioned above, the presence of particles that absorb liquid and/or swell when in contact with liquid or are soluble in liquid can impart a degree of roughness or porosity to the bristles of the brush, thereby promoting mascara adhesion and Delay it from drying out. Especially when the microparticles are adapted to produce a film, the microparticles can also deposit a film on the surface of the eyelashes, thereby improving the stability or appearance of the eyelashes, or facilitating the sliding of the applicator.

In a variant, also optionally, the applicator is constituted by an oil brush type applicator, at least one bristle of which brush consists of one of said fibers.

The packaging and/or coating device can have a flocked covering in which at least one bristle is formed from one of the fibers described. The flocked covering may cover at least a part of a component selected from the following: teeth of a comb; bristles of a brush; wiper; foam; sponge; optionally perforated membrane; rigid or flexible end piece, especially elastic body end pieces; woven fibers; and nonwoven fibers.

The diameter of the fiber may for example be in the range of 0.5 μm to 500 μm, or 50 μm to 500 μm, depending on its use, and the length of the fiber may be in the range of 0.5 mm to 50 mm, for example.

Alternatively, the fibers can constitute fillers in cosmetic or care products, especially mascara, in which case the fibers help to elongate the eyelashes. Including particles in the fibers that absorb liquid and/or swell upon contact with liquid will, for example, facilitate retention of the fibers on the eyelashes.

It is also preferred that the fibers include magnetized or magnetizable particles.

Magnetized or magnetisable particles may be incorporated into fibers already containing particles capable of absorbing or swelling upon contact with a liquid, or soluble in a liquid, or in a variant, the packaging and/or coating device may contain only Certain fibers of magnetic particles, while others contain particles that absorb liquids or swell when in contact with liquids, or are soluble in liquids. The magnetic particles may be resin coated particles, such as cyanoacrylate, or they may be formed of magnetic material deposited on a non-magnetic medium, such as glass beads or wood fibers.

The magnetic properties of the fibers can facilitate the uptake of substances and improve their application to care surfaces, or can create novel cosmetic effects.

This magnetism can also facilitate the penetration of active agents by promoting microcirculation.

Fibers can be stationary or moving.

Fibers may include a plurality of particles, which may be clay-free, and silica-free.

At least one fiber is substantially untapered.

The present invention also provides a method for manufacturing fibers suitable for use in the above-mentioned packaging and/or coating device, characterized in that the steps are as follows:

extruding or coextruding fibers of plastic material containing microparticles capable of absorbing liquids or compounds in liquid solutions, or soluble in liquids; and

The fibers are brought into contact with the liquid.

In a particular embodiment of the method, microparticles adapted to swell upon contact with said liquid are used, and the particle size of the microparticles is chosen such that the fibers have a predetermined roughness after swelling of said microparticles.

In yet another particular embodiment, when the microparticles are capable of absorbing a maintenance substance in a liquid solution, the fibers are brought into contact with said liquid and cause the fibers to be filled with the maintenance substance. The liquid can be used to cool the fibers exiting the extruder.

The invention also provides fibers suitable for use as bristles in brushes, or as flocked fibers in packaging and/or application devices for cosmetic or care products, which fibers are characterized in that, in addition to synthetic materials, Also included are microparticles capable of absorbing liquids or compounds in liquid solutions, or microparticles that are soluble in liquids.

The present invention also provides porous or coarse fibers obtained by the above method, especially fibers for coating product devices, comprising:

synthetic materials; and

Particles associated with synthetic materials, the shaped plurality of particles being capable of absorbing at least one of:

liquid and

A compound in a liquid solution and dissolves in a liquid.

A plurality of particles therein are capable of absorbing an amount of liquid at least equal to their weight.

Detailed ways

Figures 1A to 9R illustrate fibers of the present invention suitable for use in packaging and/or coating devices such as those shown in any of Figures 12 to 26.

In the example described, the fibers are produced by extruding thermoplastic material 11 containing particulate fillers capable of absorbing liquids or compounds in liquid solutions, or capable of dissolving in liquids, optionally while making the particulate fillers magnetic .

Figure 1A shows a fiber comprising a filler of microparticles 30 of a compound capable of swelling in water, before the fiber is brought into contact with a liquid, such as water, and Figure 1B shows the same fiber after contact with a liquid.

In the example shown, the fiber is solid and has a circular cross-section, but it may also have other cross-sections, as will be described later.

For example, the fibers are produced by means of an apparatus as shown in Figure 10, which comprises an extruder 20 and a coolant tank 21 in which the fibers are submerged after leaving the extruder.

The swelling of the particles 30 serves to create a relief effect on the surface of the fibers, by means of which the fibers are able to absorb, inter alia, larger quantities of substances or to better grip the eyelashes when the fibers are used, for example, as bristles of a mascara brush .

The microparticles 30 can also be used to absorb one or more substances into the fibers, such as protectants or agents with cosmetic or skin active effects.

In particular, the tank 21 for cooling the fibers leaving the extruder may comprise one or more compounds dissolved in the tank liquid, such as protective agents, which are absorbed by the particles 30 when the fibers are immersed in this tank 21 . In this way, the fibers leaving the slots 21 are filled with compounds absorbed by the particles 30 contained in the fibres. These compounds are then released gradually, for example on contact with cosmetic or care products, in order to improve their preservation. The fibers can be dewatered after leaving the tank 21 .

Alternatively, in addition to the optional microparticles 30, the fibers may contain microparticles 40 which are soluble in a liquid, such as the water of the tank 21 used to cool the fibers leaving the extruder. These particles 40 may consist, for example, of salts, sugars which are soluble in the liquid used or, when the liquid is water, of a gel. FIG. 2A shows a fiber comprising the microparticles 40 before dissolving, ie for example just after leaving the extruder 20 , while FIG. 2B shows the same fiber after passing through the slot 21 . It can be seen that the soluble particles 40 on the surface of the fiber are dissolved by the liquid in the tank 21, thereby making the fiber surface rough and even making the fiber porous. This roughness or porosity can be used, for example, to increase the amount of substance that the fibers can absorb. The amount of roughness or porosity obtained depends on the primary particle size of the microparticles 40 . When the fibers leave the slot 21, only a portion of the particles 40 need be dissolved so that the particles continue to dissolve when they come into contact with cosmetic or care products on their surface. Microparticles 40 may consist of one or more substances having a cosmetic or skin care effect. In this case, the dissolution of the microparticles 40 upon contact with the cosmetic or care product can be accompanied by the release of said substance onto the care surface. Preferably, the fibers can be vibrated to facilitate or cause the particles 40 on the surface to escape.

Alternatively, the microparticles 40 are made of a material that is insoluble in the water of the tank 21 and that only gradually dissolves in the cosmetic or care product that comes into contact with the fibers.

It is also possible to introduce microparticles 50 into fibers which are adapted to form a gel on contact with a liquid, thereby forming a layer of gel 51 on the surface of the fibers, as shown in FIG. 3 . Such a layer of gel 51 is, for example, capable of modifying the substantivity of the fibers for cosmetic or care products in contact with it. The gel can also be deposited on the care surface, such as eyelashes, to improve its stability and appearance, or to improve the slipperiness of the applicator in contact with it.

The use of particles capable of absorbing liquids, especially water, also has the advantage that cosmetic or care ingredients can be delayed on the surface of the fibers when the liquid absorbed by the particles can be gradually released in order to compensate for the evaporation of the solvent contained in the ingredients. of dry out.

The use of microparticles 30, 40 or 50 can also serve to create specific anchoring areas on the fiber surface for the substance, for example due to the affinity of the microparticles used for lipophilic or hydrophilic compounds contained in the substance. The substance may be a water/oil emulsion, the fibers may absorb only water or only oil, or more generally they absorb a compound of the substance in a selected manner.

Preferably, the particles 30, 40 or 50 may only be present on the fiber surface, as shown in FIG. 4 .

For example, the primary particle size of the microparticles 30, 40 or 50 is in the range between 1 μm and 300 μm, or between 5 μm and 200 μm, or between 10 μm and 150 μm. The concentration of microparticles 30, 40 or 50 may range from 0 to 20% by weight, alternatively from 0 to 6% by weight when dry.

The fibers may also comprise magnetic particles 12 dispersed in the plastic material 11 in a substantially uniform manner.

Alternatively, the magnetic materials 12 may be deposited only on the surface of the fibers by suitable means, such as by coating as shown in Figure 8A, or they may be confined inside the fibers, as shown in Figure 8B. The magnetic particles can also be replaced by a central core 14, as shown in FIG. 8C.

For example, the weight concentration of magnetic particles is in the range of 0.2% to 30%.

Preferably, the magnetic material used is selected from the following examples: soft magnetic materials; hard magnetic materials; ferrites, especially ferrites based on zinc, nickel or manganese; rare earths; barium sulfate; silicon alloys; Especially with molybdenum fillers; and mixtures of these materials. The magnetic particles 12 can be made by crushing a magnetic substance or by depositing a magnetic substance M on a nonmagnetic substance C, such as microbeads or wood fibers as shown in FIG. 31 . Alternatively, the magnetic particle may comprise a magnetic core M and a non-magnetic outer layer R, such as a layer of resin, especially cyanoacrylate, as shown in FIG. 32 .

Figures 5A and 5B show a fiber which, unlike the fiber in Figures 1A and 1B, has magnetic particles 12 inside it.

The fiber shown in Figures 6A and 6B is different from the fiber in Figures 2A and 2B in that it has magnetic particles 12 therein.

Figure 7 shows the fiber of Figure 3 with magnetic particles 12 dispersed throughout its volume.

Fiber cross-sections can vary widely beyond solid circular, as described below with reference to Figures 9A through 9R.

Fibers can be extruded to have a flat cross-section, as shown in Figure 9A, or a cruciform cross-section, as shown in Figure 9B, or a star-shaped cross-section with three branches, as shown in Figure 9C. The fibers can have a hollow cross-section, as shown in Figure 9D, or a solid cross-section with capillary grooves, as shown in Figure 9E. The fiber can also have a U-shaped cross-section, as shown in Figure 9F; an I-shaped cross-section, as shown in Figure 9H; a T-shaped cross-section, as shown in Figure 9I; a V-shaped cross-section, as shown in Figure 9J, and a Z-shaped cross-section, such as As shown in FIG. 9K, or a combination of the above-mentioned specific shapes, for example, as shown in FIG. 9G, a combination of shapes in FIGS. 9B and 9C. Figure 9L shows fibers with a hollow, square cross-section; Figure 9M shows fibers with a solid, square cross-section; Figure 9N shows fibers with a hollow, star-shaped cross-section; Figure 9P shows fibers with a hollow, triangular cross-section; Fibers formed with peripheral grooves; Figure 9R shows fibers with kidney-shaped cross-sections.

When the fiber contains magnetic particles, the fiber may be exposed to a magnetic field in order to be magnetized, for example in order to magnetize the fiber to a predetermined polarity. This can be done as the fibers leave slot 21, for example by means of magnetization 60, as shown in FIG. Preferably, the magnetization of the fibers is also carried out after the fibers have been loaded into the packaging and/or coating device by applying a magnetic field to the device or to a batch of such devices. The magnetization of the fibers is only to enable easier manufacture by limiting the risk of the fibers clumping together when they are arranged in place within the packaging and/or coating device.

The fiber can be used in a variety of applicators and packaging devices, as described below.

FIG. 12 shows a packaging and applicator device 100 comprising: a container 101 containing a substance P for application, such as mascara; and an applicator 102 . The container 101 has a wiper 106 which, in a variant not shown, can be covered with fleece. The applicator 102 comprises a rod 103 having at one end a handle 104 which also constitutes a sealing cap for closing the container 101 and having a brush 105 at its other end. The brush comprises a core of twisted metal wires filled with bristles of the aforementioned fibers, which optionally include magnetic particles.

When the fibers comprise magnetic particles, the magnetic poles of the brush can be oriented eg along the axis of the rod 103 or perpendicular to the axis of the rod 103 . The twisted core may be made of a non-magnetic material, such as non-magnetic stainless steel, or in a variant it may be made of a magnetic material. In this way, the core interacts magnetically with the bristles. The bristles of the brush 105 may be magnetized, such that the magnetization of the brush bristles acts on adjacent bristles, and the magnetic interaction between the bristles, for example, serves for proper positioning of the bristles. Depending on the orientation of the brush poles, the effect on bristle orientation can vary. For example, Figures 28A and 28B illustrate the lateral deflection effect on the bristles of a brush as the magnetic field extends laterally. Optionally, the bristles are used alone when applying the substance to the eyelashes in order to apply a beneficial magnetic field to the eyelashes or to a part of the face, such as the eyelids. The magnetic field applied by the bristles of the brush tends to change over time, especially when the structure of the brush changes, for example when the applicator is withdrawn or when a substance is applied. The substance P may be magnetic, for example it may contain magnetizable or magnetized particles. When the substance P is magnetic, the brush bristles which are also magnetic may enhance the brush's ability to pick up the substance, for example by magnetic attraction between the substance and the brush bristles. Alternatively, the substance may contain magnetic fibers or flakes, and the applicator may magnetically interact with these flakes in order to align them in a particular direction when applied, eg to facilitate sliding of the applicator.

Figure 13 has shown the device 110 that is used for packaging and coating nail polish, and this device comprises a container 111 and an applicator 112, and this applicator comprises a rod 113, and this rod 113 has handle assembly 114 at its one end, and this The handle assembly 114 also forms the cap for closing the container, and the rod 113 has at its other end an oil brush 115 comprising bristle tufts that are relatively tightly packed together. The bristles are made using the fibers of the present invention and they can optionally be magnetic which can be used to orient the bristles of the brush 115 in use, thereby making it easier for the brush 115 to pick up substances or act on the care surface . When there is a magnetic interaction between the bristles of the brush, this magnetic interaction can facilitate bunching the bristles together or, conversely, spreading them apart, depending on the magnetic field polarity of each bristle. For example, Figures 29A and 29B show very schematically the effect of the bristles being splayed due to the magnetic interaction between them. Substance P can be chosen to have its own magnetic properties.

Fig. 14 has shown a kind of packaging and coating device 120, and this packaging and coating device 120 comprises a container 121, and this container 121 is equipped with material P, for example liquid lipstick, and this device 120 also has a applicator 122, and this coating Device 122 comprises a rod 123, and this rod 123 has cap body 124 at one end, is used for closing container 121 and as handle, and has an applicator end piece 124 at the other end of this rod, and this applicator end piece 124 Covered by flocking made from fibers of the invention, which may optionally be magnetic. The device 120 also has a wiper consisting of a block 125 of foam material. The foam block can optionally also be magnetic. In particular, the block of foam material 125 may be magnetized to a certain extent by including magnetic particles therein. The magnetization of the wiper element can, for example, magnetize the flocking on the end piece 124 when the applicator 122 is withdrawn.

Figure 15 shows a device 130 for packaging and applying a substance P, in particular a liquid lipstick, comprising an end piece 131 covered by a flock 132 made of fibers according to the invention , the fibers can optionally be magnetic.

Figure 16 shows an oil brush 140 for powder application, the bristles of which are made of fibers according to the invention, which fibers may optionally be magnetic.

Figure 17 shows an applicator 150 comprising a foam 151 whose surface is covered by a flock 152 made of fibers according to the invention, optionally magnetic. The applicator can be used, for example, to apply blush to the skin.

Fig. 18 A has shown a kind of liquid lipstick applicator 160, and this liquid lipstick applicator 160 comprises a flocking elastomer end piece 161, and Fig. 18 B has shown eyeliner 160 ', and this eyeliner 160 ' also comprises a planting The end piece 161' of fleece elastic body. In both cases, the bristles used for the flocking are made from fibers according to the invention, which may optionally be magnetic.

The fibers of the present invention can also be used to flock a powder puff 170 as shown in FIG. 19 , or a makeup remover sponge 180 as shown in FIG. 20 .

The flocked coating may also extend onto a membrane 191 secured to a block of foam material 192 , in which case an applicator 190 is shown in FIG. 21 .

It is also possible to use the fibers of the present invention in a disc 200 or towelette, which may optionally be magnetic, and which comprises at least one layer 201 of nonwoven or woven fibers comprising said fibers, as shown in Figure 22 shown.

Figure 23 shows a comb 210 having flocked teeth 211 for applying a substance to the eyelashes. The flocked bristles can be made from fibers according to the invention, which fibers can optionally be magnetic.

In addition to the fibers being magnetic, the applicator may optionally include one or more single-piece magnets.

For example, Figure 24 shows an applicator 220 that includes a handle 221 with a magnet 222 secured thereto. The magnet is covered by a block of foam material 223 which itself is covered on the outside by a flock 224 consisting of magnetic fibers. The presence of magnets 222 is effected by the bristles of flocking 224 being subjected to a magnetic field. In particular, the flocked bristles of the bottom dielectric connection extend along the magnetic field lines M substantially perpendicularly, as shown in FIG. 27 . The bristles will stand upright on the surface of the applicator assembly, or protrude in other directions depending on their position relative to the magnet 222, allowing the applicator to absorb a larger amount of material or allowing the applicator to absorb a larger amount of material. Cloth is softer. Furthermore, when the substance is a powder that will come into contact with the applicator, and when the applicator is magnetic, particles of the powder will be deposited on the applicator, especially on its fibers, thereby reducing the chances of the powder spreading. Blowing and sneezing hazard.

In the device 230 shown in Figure 25, the substance is contained in a flexible bag 231 and a pump 232 is mounted on top of the flexible bag. The applicator includes a foam material 234 , the surface of the foam material 234 is covered by flocking 235 , and the foam material 234 is fixed on the cap body 236 . Magnet 237 is encased in foam material 234 and mounted on cap 236 . The bristles of the flock 235 are made using the fibers of the present invention, the fibers are magnetic, and the bristles are affected by the magnetic field of the magnet 237, as described in the previous embodiments.

Figure 30 shows a portion of applicator 280 which includes a flocked end piece 282 which fits within cap body 281 when not in use. By using fibers containing agents that absorb water or swell in the presence of water, it is possible to keep it damp within the cap body, thereby delaying the drying of the end piece, which can also be replaced by other applicator components, such as a brush .

Naturally, the present invention is not limited to the above-described embodiments.

In particular, there is a screen 240 between the applicator and the contents of the container, as shown in FIG. 26 . In this case, the substance P can contain magnetic particles 241 and the applicator can be magnetic, for example consisting of an end piece with a flocked coating made of magnetic fibers according to the invention. The end piece 242 can absorb the magnetic particles 241 contained in the substance. By properly selecting the aperture of the screen 240, it can be ensured that the magnetic particles 241 attracted by the end piece 242 cannot pass through the screen 240, but play a role in causing the substance P to move towards the end piece 242, thereby improving the tail end. The ability of member 242 to absorb the substance. In a variant, the substance P is itself magnetic, for example containing coated magnetic particles, and this substance P is able to pass through the pores of the screen 240 .

The fiber may be magnetized only over part of its length.

The packaging and coating devices described above may comprise magnetic fibers mixed with non-magnetic fibers filled with microparticles of a compound capable of absorbing liquid and/or adapted to swell when in contact with a liquid, or capable of To dissolve, the liquid may be, for example, water.
