Abstract

Roll-on deodorant or ballpoint pen has a ball (1) which is mounted in a flexible tube (5) so that it can rotate. A cap (8) is screwed on to it which forms a seal with the top (6) of the tube but does not contact the ball.

Description

The invention relates to an applicator for liquids, flowable formulations, pastes, Powder and the like, consisting of one storage and one in storage held, rotatable body and a protective cap and the use of a rotatable body for the application of substances to a substrate.

Devices in which a freely rotatable ball in a bearing for the application of Liquids used on a substrate have long been known in large numbers. Such ball application devices are often designed such that the ball on one ring-shaped sealing seat rests and in a holder or bearing seat included, which is located above the seal seat. The ball sticks out with part of your surface out of the holder seat, another part protruding part opposite part of the surface dips into the part to be dispensed Liquid.

If the ball is now rolled over a substrate, the ball adheres as part of the liquid thin layer on the surface and turns outwards during the rotation transported so that the wetted surface becomes the exposed spherical part. From here the liquid can now be easily applied to the substrate during the rolling motion become.

In addition to, for example, ballpoint pens in which ink is rolled onto the Such a device is used primarily for the desk pad Application of liquids in the cosmetic and dermatological area.

Such ball application devices are preferred on a bottle with the liquid to be applied, the bottle with a screw cap can be closed.

DE 11 76 802 A1 already describes a ball application device for cosmetic products and the like for a container provided with an opening with which a resilient resilient bearing piece covering the edge of the container opening is engaged, described, wherein the bearing piece is provided with a lower annular seal seat against which a ball is enclosed by the bearing piece above the seat and partially protrudes beyond the bearing piece, can be pressed in that the inner Lid part of a detachably engaged with the container and the bearing piece free overlapping cap directly on the protruding part of the bearing Ball pushes. The cap has a shoulder that is against a shoulder of the Bearing piece sets.

Such an application device is modified in DE 31 04 525 A1, this document explains a ball application device with a screw cap for a bottle for cosmetic products an annular bearing piece which can be firmly connected to the edge of the bottle and which has a has lower sealing seat and an upper bracket seat for a ball. At the Screw cap and the bearing piece are interlocking snap, snap or clamp connection parts for detachable connection between the bearing piece and Screw cap arranged.

A problem with applicators such as those described above is that the Ball can dry out: So that there is permanent liquid on the outside of the applicator can be transported, the ball must be immersed in the liquid. that such application devices do not work in all positions. When sinking Liquid level or when the device is tilted is not the wetting of the ball guaranteed and the application device is no longer functional.

The is therefore concerned with the problem of conveying the liquid under the ball DE 42 15 966 A1. A cosmetic roller with an elastic container or is presented here Container part with an application element, designed as a ball or roller and with one Bearing on which a movable, tubular conveyor is arranged, the one or is in several parts and / or provided with a mass piece at the end, with a fit insert with integrated storage space with capillaries running axially on the inside and with molded on Funding or with tubular funding either in one piece with one Fitment cosmetic roller containers manufactured together, in a separate fitment or in an extended fit is arranged.

DE 198 27 965 also deals with the solution to the problem of wetting the Allow ball regardless of the position of the ball. For this, a Ball applicator offered, consisting of a ball, a ball holder and a storage container, wherein (a) at least one of the storage chambers beneath the ball is arranged, (b) the storage chambers via openings with the liquid container are connected, (c) one of the walls of the pantries through a portion of the surface the ball is formed.

The formation of the application ball takes into account EP 0 792 635 A2, which a Claimed antiperspirant, which is packaged in a storage container, the Storage container has a ball with a diameter of at least 3 cm, and wherein the antiperspirant is composed of 10 to 70% by weight of ethanol, up to 1% Thickener, 5 to 20% by weight of an antiperspirant active ingredient and up to 5% by weight a fluidity increasing agent.

Structured applicators are used to apply hot glue (DE 298 05 517 U1) and fluid solids (GB 2 108 052 A) have already become the state of the art.

A sealing and fixing of the application body is described in US Pat. No. 4,168,128 Made of flexible materials, especially polymer foams, which are in the cover cap located and rest on the applicator body in the closed state. there but the seal is from that on the surface of the application body Substrate wetted and dirty. Especially with adhesives or substrates evaporating solvents lead to the formation of irreversible residues and Encrustations.

A disadvantage of all the previously described systems with a smooth application body is that limited wettability of the application ball or its quantity only limited Transportability for liquids. Another disadvantage of all systems is that one The ball for wetting the surface must first be "mechanically activated" when the Applicator of the longer was not used: due to the small amount of liquid on it the outside of the ball dries it relatively quickly, so that the ball is first has to turn over a few times so that the surface is completely back with the substrate to be applied is wetted.

It is therefore the object of the invention to offer an applicator which does the above Disadvantages of the prior art does not exist or only to a reduced extent. This Applicator should have an application system in which the liquid availability during the order process is increased. The probability of tearing off the Liquid film during the application process should be reduced as well Drying out of the applicator during phases in which the applicator is not used so there should be immediate product availability. Furthermore, the applicator have better rollability.

This task is surprisingly solved by an applicator as in the main claim is described. In this case, in particular a rotatable one is used as the application device geometric body (hereinafter referred to as the application body) into an annular Bracket (hereinafter referred to as fitment) used and with one on the fitment matched cap closed. The subclaims relate to advantageous ones Embodiments of this applicator. The use of a is still claimed such a rotatable body with a structured surface for the application of Substances on a substrate.

Accordingly, the main claim describes an applicator for liquids, flowable formulations, pastes, powders and the like (hereinafter referred to as fluid), consisting of a bearing and a rotatable one that is kept in the bearing geometric body, the rotatable geometric body having at least one Part of its surface protrudes from the storage.

The flowable formulations are preferably emulsions, Suspensions, colloids, dispersions, gels or solutions.

In a first embodiment of such an inventive applicator rotatable body is a rotationally symmetrical geometric body.

In a very advantageous further embodiment, the structuring Depressions are formed in the surface, in particular elevations in a symmetrical manner Arrangement. The application body is in a further variant of the inventive applicator structured by indentations on the surface.

The elevations in the surface of the application body are very preferably in the form of Knobs, cuboids, pyramids, trapezoids, cylinders and the like before. Without However, all increases for the inventive applicator can be restricted here Use increased functionality, for example, increases in the form of Ornaments, figures or characters and the like.

For the inventive applicator, the two variants described below are shown in inventive sense very cheap: On the one hand, the increases can be arranged and be dimensioned such that the elevations are separate from one another, for example in the trapezoids mentioned above if they are not in contact with each other ( "Open pore"). On the other hand, the increases can be related to each other, so that there is a "labyrinth system" in the macroscopic surface of the sphere ("closed-pore"; in an alternative view, this is equivalent to that above mentioned bumps on the spherical surface when the "bottom" of the channels as macroscopic surface of the sphere is viewed).

The amount of liquid transported is increased by the attached increases. In addition to the known wetting of the macroscopic surface of the The body collects the liquid in the recesses between the ridges like in small pots and is used by them, similar to the way a Paddle wheel pump, transported to the surface.

Likewise, the substance to be dispensed can be delivered through the structured application body Application to the substrate can be dosed much better.

A symmetrical arrangement of the depressions on the application body leads in comparison to an asymmetrical arrangement to a more uniform liquid distribution the surface and thus to improved order behavior.

In a further improved embodiment of the inventive applicator Application body a ball, an ellipsoid or a roller. Such forms are with macroscopically smooth surfaces known for applicators on the market. Other well-suited shapes for the rotatable application body of the inventive Applicators are, for example, cones, hyperboloids, rotating paraboloids and or cutouts or stumps of these geometric bodies as well as irregular ones geometric body. The latter can be suitable, for example, on uneven surfaces Substrates to achieve an optimized application.

The inventive applicator is particularly advantageous as part of the substance to be dispensed containing container, in particular a bottle-like container. The inventive one Applicator can then be used as an application device for liquid delivery systems use which, for example, the previously known deodorant or antiperspirant controllers equivalent.

The bearing preferably consists of a plastic fiber, consisting of a ring, whose shape essentially takes up the shape of the application body and Inner diameter is slightly larger than the outer diameter of the application body (In the case of elliptical bodies, the two semi-axes are correspondingly somewhat larger than those of the applicator).

Furthermore, this fitment is based on a spherical application device (ball) explained, the shape of the fitment corresponding to that for differently shaped application bodies The shape of the order body must be adjusted and the description transferred accordingly can be.

Down this ring is through a support bed for the ball, which for Storage vessel has an opening, closed, from this side the ball wetted with the substance to be applied. This side of the fit is preferred on the Put on the substance containing substance to be applied or fitted into this. In In one variant, the fitment and the storage vessel are designed in one piece.

The ring tapers slightly towards the top, so that the diameter of the remaining opening is slightly smaller than the diameter of the ball. The ball can now be inserted into the fitment with slight pressure, "snapping" into it and does not fall out of its own accord. It protrudes from the surface with part of its surface Fitment out and is freely rotatable in all directions, so by a rolling motion like described the substance can be applied to a substrate.

In a variant of this fit, there is no complete ring, but there are at least two, preferably at least three ring cutouts are present to close the ball hold. These are shaped so that the ball after snapping does not fall out of the fitment. However, this form of fitness requires additional Effort for sealing to the storage container.

In the case of a roller-shaped application device, the storage consists of two opposite walls, which also have a support bed at the bottom an opening to the storage vessel and upwards with a taper to the other Wall to be completed. In a preferred embodiment, the two are Side walls thereby sections of a tube, the diameter of which is slightly larger than that Diameter of the roller. This tube cutout can go through to the front and back two plane-parallel walls can be closed.

Choosing the dimensions of the inventive surface-structured sphere, ellipsoid or corresponding to the roller, the structured systems can be divided into the known ones Use storage systems. This procedure allows the previous Manufacturing facilities largely continue to use what the financial expenses Manufacturing of the inventive applicators significantly reduced.

In a very preferred embodiment, the storage of the inventive applicator is these are connected to the opening of a storage vessel in such a way that the content of the Can be dispensed by pressing the applicator.

In its advantageous embodiment of the applicator, the storage vessel is thereby a lid, which when closing the opening of the storage vessel with the Applicator covered, closed. Here, the seal between the lid and the fitment instead. The fit is preferably at least on the outer side made of an elastic material, which in the closed vessel on the Bears against the inside of the lid and thereby seals. For this, the The inside of the lid and / or the outside of the fitment advantageously with one shoulder or the like, which enhances the sealing effect.

For the purposes of the invention, the fit is also pressed against the rotating body the attached lid. This will cause the product to flow out into the Lid gap prevents, which is particularly the case with non-vertical storage is. The exposed surface of the rotating body is thus only wetted during use, which greatly simplifies dosing.

The inner surface of the lid is very preferably shaped in such a way that it has the shape of the Fitments with the order body located therein, but not on this Position rests. In the closed system there is then the space between the applicator and the inside of the lid is very small. Due to the small air space, drying of the Filling greatly reduced.

In the usual embodiments of the inventive applicator, the application body is free in all spatial directions rotatably fitted in the storage, this applies in particular to the rotationally symmetrical application body. In a further advantageous embodiment the application body is additionally supported on at least one axis of rotation. This gives the Storage additional stability and further prevents the application body from the Applicator can fall. It is also possible to specify the direction of rotation of the body which enables additional possibilities in the design of the surface geometry. The surface structures can be arranged symmetrically about the axis Further optimize the transport properties of the application device.

Both the axle in its axle bearing and the one that can rotate Order body can be rotated on the axis.

With the applicator according to the invention, liquid and flowable substances can be easily and easily distributable solid substances as well as mixtures of two or more components be applied, the applicator also being excellently suited for emulsions, Suspensions, dispersions, solutions (gaseous, liquid and solid substances), colloids and the same.

The inventive applicators for applying cosmetic are very preferred or dermatological agents used on the skin, especially gels, Emulsions, Pickering emulsions, hydrodispersions, lipodispersions.

In the technical sense, gels are understood to mean: Relatively stable, light deformable disperse systems from at least two components, which usually consist of a - mostly solid - colloidally divided substance from long-chain molecular groups (e.g. Gelatin, silica, polysaccharides) as a scaffold and a liquid Dispersing agents (e.g. water) exist. The colloidally divided substance is often called thickening or Called gelling agent. It forms a spatial network in the dispersant, whereby individual colloidal particles through electrostatic interaction with each other can be more or less firmly linked. The dispersant, which is the network surrounds, is characterized by electrostatic affinity for the gelling agent, d. i.e., a predominantly polar (in particular: hydrophilic) gelling agent preferably gels polar dispersant (especially: water), whereas a predominantly non-polar one Gelling agent preferably gelled non-polar dispersing agent.

Strong electrostatic interactions, for example in Hydrogen bonds between gelling agent and dispersing agent, but also between Dispersant molecules are realized with each other, can also lead to strong crosslinking of the dispersant. Hydrogels can consist of almost 100% water (in addition, for example, about 0.2-1.0% of a gelling agent) and quite solid Have consistency. The water content is in ice-like structural elements.

Cosmetic and pharmaceutical galenics also include lipogels and oleogels (from waxes, fats and fatty oils) and carbogels (from paraffin or petrolatum) common. In practice, a distinction is made between oleogels, which are practically anhydrous, Hydrogels, which are practically fat-free. Most of the time, gels are transparent. In the Cosmetic or pharmaceutical galenics are generally characterized by gels semi-solid, often flowable consistency.

So-called surfactant gels are also common preparations of the prior art. This means systems that, in addition to water, have a high concentration of emulsifiers have, typically more than about 25 wt .-%, based on the Total composition. Solubilized in these surfactant gels, also in technical terms Called "surfactant gels", oil components, microemulsion gels are obtained, which also be called "ringing gels". By adding nonionic emulsifiers, For example, alkyl polyglycosides, cosmetically elegant microemulsion gels receive.

Emulsions are metastable two- or multi-phase systems in which the individual Phases are in the liquid state. The most common emulsions are O / W and W / O Emulsions. More rare forms of administration are multiple emulsions, i.e. those which are in the droplets of the dispersed (or discontinuous) phase, in turn, droplets one contain another dispersed phase, e.g. B. W / O / W emulsions and O / W / O emulsions. In simple emulsions are finely dispersed in one phase, from an emulsifier shell enclosed droplets of the second phase (water droplets in W / O or lipid vesicles in O / W emulsions). The droplet diameters of the ordinary emulsions are in the Range from approx. 1 µm to approx. 50 µm. Such "macro emulsions" are without further coloring Additives, colored milky white and opaque. Finer "macro emulsions", their Droplet diameters are in the range from approx. 101 µm to approx. 1 µm, again without coloring Additives, colored bluish white and opaque.

Micellar and molecular solutions with particle diameters smaller than approx. 10 ^-2 µm appear clear and transparent.

The droplet diameter of transparent or translucent microemulsions, however, is in the range from about 10 ^-2 µm to about 10 ^-1 µm. Such microemulsions are usually of low viscosity. The viscosity of many O / W type microemulsions is comparable to that of water.

By far the most important product type in the field of skin care products or in Cosmetic and / or dermatological preparations represent emulsions. Emulsions are disperse two- or multi-phase systems, with cosmetic emulsions from at least one fat phase (fats and mineral oils, fatty acid esters, fatty alcohols etc.) and at least one water phase (water, glycerin, glycols etc.), which with With the help of emulsifiers in the form of very fine droplets. Are the two Liquids water and oil and if there are oil droplets dispersed in water, so it acts an oil-in-water emulsion (O / W emulsion, e.g. milk). The basic character of one O / W emulsion is characterized by the water. With a water-in-oil emulsion (W / O- Emulsion, e.g. B. Butter) is the opposite principle, the Basic character here is determined by the oil.

The oil phase is advantageously selected from the group of the esters from saturated and / or unsaturated, branched and / or unbranched alkane carboxylic acids and saturated and / or unsaturated, branched and / or unbranched alcohols, from the group of Esters of aromatic carboxylic acids and saturated and / or unsaturated, branched and / or unsaturated alcohols, from the group of branched and unbranched Hydrocarbons and waxes, the silicone oils, the dialkyl ethers, the saturated group or unsaturated, branched or unbranched alcohols, and the Fatty acid triglycerides. Any mixtures of such oil and wax components are also advantageous in To use the sense of the present invention. It may also be advantageous if Waxes, for example cetyl palmitate, as the sole lipid component of the oil phase use.

The oil phase can advantageously contain cyclic or linear silicone oils, for example cyclomethicone (octamethylcyclotetrasiloxane), or have completely such oils exist, although it is preferred, except the silicone oil or Silicone oils to use an additional content of other oil phase components. The The emulsions described here and below can accordingly be found under Manufacture partial or complete use of silicone oils as silicone emulsions. The same applies to the other oil-containing preparations.

A multitude of possibilities is known to the person skilled in the art for stable O / W preparations for formulate cosmetic or dermatological application, for example in the form of creams and ointments that are spreadable from room temperature to skin temperature, or as lotions and milks, which are more fluid in this temperature range and themselves can be applied particularly cheaply with the applicator according to the invention.

The stability of emulsions depends, among other things, on their viscosity, in particular that of Viscosity of the outer phase depends. An emulsion becomes unstable when the aggregate finely dispersed particles again to form larger aggregates touching droplets flow together. This process is called coalescence. The process of coalescence is slower, the more viscous the outer phase of the Is emulsion.

Accordingly, O / W emulsions are usually thickeners, which increase the viscosity of the aqueous phase, stabilized. For example, are suitable for this Polyacrylates (carbomer) and other organic thickeners. One disadvantage of this The method of improving stability is the sensitivity of these formulations to Electrolytes. Furthermore, in this way, naturally, the viscosity is primarily higher To produce formulations (such as creams or ointments).

The applicator according to the invention is outstanding due to its special structure suitable to deliver emulsions thickened in particular evenly.

Emulsions of "liquid" (= flowable) consistency can be found in cosmetics, for example as deodorants or antiperspirants, as care, cleaning, face or hand lotion Use. They usually have a viscosity of around 2000 mPa.s up to around 10,000 mPa.s. Particular attention is paid to the stability of flowable emulsions dedicate, because the significantly greater mobility of the particles a faster coalescence promotes.

• - Das wohl bekannteste Beispiel eines anionischen Emulgators ist die Seife, als die man gewöhnlich die wasserlöslichen Natrium- oder Kaliumsalze der gesättigten und ungesättigten höheren Fettsäuren bezeichnet.
• - Wichtige Vertreter der kationischen Emulgatoren sind die quartären Ammonium-Verbindungen.
• - Der hydrophile Molekülteil nichtionischer Emulgatoren besteht häufig aus Glycerin, Polyglycerin, Sorbitanen, Kohlenhydraten bzw. Polyoxyethylenglykolen und ist meistens über Ester- und Etherbindungen mit dem lipophilen Molekülteil verknüpft. Dieser besteht üblicherweise aus Fettalkoholen, Fettsäuren oder Isofettsäuren.

Conventional emulsifiers can be divided into ionic (anionic, cationic and amphoteric) and nonionic according to their hydrophilic part of the molecule:

• - The best known example of an anionic emulsifier is the soap, which is usually referred to as the water-soluble sodium or potassium salts of the saturated and unsaturated higher fatty acids.
• - The quaternary ammonium compounds are important representatives of the cationic emulsifiers.
• - The hydrophilic part of the molecule of nonionic emulsifiers often consists of glycerin, polyglycerin, sorbitan, carbohydrates or polyoxyethylene glycols and is usually linked to the lipophilic part of the molecule via ester and ether linkages. This usually consists of fatty alcohols, fatty acids or isofatty acids.

By varying the structure and size of the polar and non-polar part of the molecule lipophilicity and hydrophilicity of emulsifiers can be changed within wide limits.

The right choice of emulsifiers is crucial for the stability of an emulsion. The characteristics of all substances contained in the system must be taken into account. Looking at z. B. skin care emulsions, lead polar oil components and, for example UV filter to instabilities. In addition to the emulsifiers, other stabilizers are therefore also used used, for example, increase the viscosity of the emulsion and / or as Protective colloid act.

The use of the usual emulsifiers in cosmetic or dermatological preparations harmless. Nevertheless, emulsifiers, like ultimately every other chemical substance, in individual cases allergic or hypersensitive to the user elicit responses. There has been no shortage of attempts, the amount of usual emulsifiers to a minimum, ideally even completely reduced.

A reduction in the amount of emulsifier required can, for. B. can be achieved if is exploited that finely divided solid particles have an additional stabilizing effect. The solid substance accumulates at the oil / water phase boundary in the form of a layer, which prevents the disperse phases from converging. It is not the chemical that is essential, but the Surface properties of the solid particles.

A relatively new technical development is cosmetic or dermatological Stabilize preparations only with finely divided solid particles. Such According to their inventor, "emulsifier-free" emulsions are also called Pickering emulsions designated. One way to stabilize a solid in a cosmetic or dermatological preparation is, according to May-Alert (pharmacy in our time, 15th year 1986, No. 1, 1-7) for example, to use emulsifier mixtures which both contain anionic as well as cationic surfactants. Because when combining anion and cationic surfactants always fail to form insoluble, electroneutral compounds through targeted precipitation of these neutral surfactants in the oil / water interface achieve additional solid stabilization in the sense of a Pickering emulsion.

Furthermore, WO publication WO-98/42301 describes emulsifier-free finely dispersed systems from Type water-in-oil, which is caused by the addition of micronized, inorganic pigments are stabilized, selected from the group of metal oxides, in particular titanium dioxide become.

Emulsifier-free preparations based on so-called hydrodispersions have been in use for some time accessible to the consumer. Hydrodispersions are dispersions of a liquid, semi-solid or solid inner (discontinuous) lipid phase in an outer aqueous (continuous) phase.

In contrast to O / W emulsions, which are characterized by a similar phase arrangement distinguish, but hydrodispersions are essentially free of emulsifiers. Like emulsions, hydrodispersions are metastable systems and are inclined to one State of two coherent discrete phases. In emulsions the choice of a suitable emulsifier prevents phase separation.

In the case of hydrodispersions of a liquid lipid phase in an outer aqueous phase, the Stability of such a system can be ensured, for example, that in the aqueous phase, a gel structure is built up in which the lipid droplets are stable are suspended.

In reverse analogy, W / O lipodispersions are finely dispersed emulsifier-free Water-in-oil preparations.

The preparations described above form the basis for cosmetic Deodorants / antiperspirants, so all common active ingredients can be used advantageously, for example odor maskers such as the common perfume ingredients, odor absorbers (for example layered silicates, also zinc salts of ricinoleic acid), germ-inhibiting agents. Furthermore, the customary antiperspirant active ingredients can advantageously be added, especially astringents, for example basic aluminum chloride hydrates. As Antiperspirant active ingredients have long been known in aluminum salts. Aluminum chloride, Aluminum chlorohydrate, nitrate, sulfate, acetate, etc. have been used for several years antiperspirant or antiperspirant active ingredients are used. In addition, zinc, Magnesium and zirconium compounds application. The state of the art described for example in: H. P. Fiedler, The Sweat, Editio Cantor, Aulendorf, 2nd edition, Pp. 303-377, Chapter K: "Agents to inhibit perspiration". Of those there as Antiperspirant active ingredients described metal compounds have been used in cosmetic and dermatological antiperspirants only the aluminum salts and - in somewhat less - the aluminum / zirconium salts prevailed. These can be found here as well as other metal and non-metal antiperspirant active ingredients.

Some examples of deodorants or antiperspirants in the form of gels and emulsions, for which the inventive applicator can be used excellently, are summarized in the following two tables.

The constituents mentioned under (a) are dispersed. Water (c) is added, allowed to swell at room temperature, a solution of the constituents mentioned under (b) is added after about 15 minutes. The resulting mixture is homogenized and can be filled.

The constituents mentioned under (a) and (c) are in each case stirred at 75 ° C. heated. Then components (a) are added to (c). The mixture is brought to 35 ° C cooled. A solution is prepared from the components (b) and heated to 35 ° C and added to the mixture of (a) and (c) with stirring.

Another antiperspirant preparation, for which the inventive applicator is particularly well suited, is composed according to the following list:

PREPARATION

For all the preparations and agents described above is the invention Applicator excellently suitable and represents a state of the art significant advantages. Particularly sensitive multiphase systems are between the increases in the applicator body of the inventive applicator less Exposed to stress than on the conventional macroscopically smooth Order bodies. Dispersions, in particular solid-in-liquid systems, can also be used Apply better with the applicator according to the invention, since the solid substances in the Wells of the application body more advantageously on the dispensing side of the applicator can be transported.

These and other cosmetic and dermatological preparations can be used together with the inventive applicator very advantageously in the form of deodorant and / or Antiperspirant sticks, lip care sticks, medical or dermatological Treatment pens for skin diseases, masking pens for blemishes, pens in the field of decorative cosmetics (for example decorative lipsticks or kohl pencils) to only to mention a few examples from the very broad field of applications.

Part of the invention is thus also the use of a rotatable geometric Body with such a structured surface that through the structuring in particular depressions are formed in the surface for the application of Substances on a substrate, preferably for the application of cosmetic or dermatological preparations, in particular deodorants and / or Antiperspirants, very preferably those containing Al and / or Al / Zr complexes Deodorants and / or antiperspirants, on the skin.

The cosmetic or dermatological preparations can advantageously be in the form of gels, emulsions, microemulsions, suspensions, dispersions, colloids, powders, Powders and / or pastes are present.

Part of the invention is also the use of the applicator described in the foregoing, which is characterized by a rotatable geometric body for Application of substances to a substrate, in particular in one or more im details described above. For this purpose, all described embodiments are of the inventive applicator excellently suitable.

Nevertheless, the use of the inventive applicator can also be used anywhere there where it can be of interest to apply liquids precisely or in lines, for example in the field of liquid adhesives, pharmaceutical agents, Detergents (e.g. for stain removers), food and the like. Also the use as an ink application ball in ballpoint pens and other pens lends itself to the inventive applicator. Especially for higher viscosity Writing fluids, for example for the paint color in paint pens, is a structured one Application body particularly well suited.

It should not go unmentioned that the inventive applicator is due to the Structuring of the application ball is particularly suitable, especially highly viscous, to transport greasy substances for the conventional applicators not or only would be very bad. An example of this is the one already mentioned above Use for decorative lipsticks, the composition of which in general Fat based.

If the inventive applicator is dimensioned accordingly, it can also be used for Use liquid films on larger areas. Here you can Example applicators in which the rotatable application body from a corresponding structured roller, for applying wall paint for decoration and Use for renovation purposes or to apply protective films. The is preferred Roll additionally from an absorbent material. An advantage over the previous ones A free axis of paint rollers made of fur-like material results from the fact that the Applicator system already brings its ink reservoir, so that much cleaner than can be worked so far. Instead of dipping the paint roller into the paint bucket again need, the applicator by a suitable adapter system, for example by a screwing device to be placed on a newly filled storage vessel.

At the same time, the application device can be designed such that the Cleaning process - compared to fur rolls, which are laboriously washed out need - is made considerably easier, for example by simply rinsing for cleaning sufficient.

The dimensions of the applicator according to the invention can each have the desired function or use can be adjusted. So for an application device for deodorant and / or antiperspirant roller particularly preferably balls with a diameter of 10 up to 50 mm, in particular from 20 to 35 mm, very preferably from 28 to 30 mm. In one of the preferred variants here are round trough-shaped depressions, each with a diameter of 2 to 5 mm.

For use as an applicator for lipsticks, one can preferably use balls with a Use a diameter of 5 to 20 mm.

In addition to the advantages already described with regard to the application properties for The applicators according to the invention have liquids in the personal care field due to the massage effect caused by the changed surface additional benefit for the user. While applying cosmetic or dermatological preparations can also have a positive effect, for example for the Skin tightening or against cellulite can be achieved.

The application body can be made of metal, glass, ceramic, porcelain or a suitable one Plastic. It is very cheap to use polypropylene as the material. Especially for the use as an applicator for adhesives offers materials that are not or badly stick, especially Teflon.

Thermoplastics, elastomers or combinations of are generally very suitable Plastics from these groups. Their properties can be determined by adding Plasticizers, fillers, stabilizers and other additives as well Vary fiber reinforcement widely. As examples of thermoplastic and elastic Plastics are mentioned: all made of linear or thermolabile cross-linked polymer molecules existing plastics, e.g. B. polyolefins, vinyl polymers, polyamides, polyesters, Polyacetals, polycarbonates, e.g. T. also Polyurethane u. ionomers; TPE-S (styrene oligoblock Copolymers), TPE-O (thermoplastic polyolefins), TPE-U (thermoplastic Polyurethanes), TPE-E (corresponding copolyesters), TPE-A (corresponding copolyamides), Natural and synthetic rubbers.

It may be advantageous for the application device to have appropriate application an absorbent material or a non-absorbent core, which is surrounded by an absorbent layer. Due to the thickness of this layer, the Dose the quantity dispensed additionally: Thick absorbent layers can be large Absorb and dispense amounts of liquid per "rolling process", thin absorbent Layers are suitable for an economical application process.

Due to the application device coated with an absorbent material, one is already Given an example of application devices that consist of more than one material. Such application devices can also be used, for example, in two-component injection molding from two or more different or from two or more different colored or colored materials are produced.

Application devices, which for example have a dark "core" and a light "envelope" have, which has the depressions, have in the dry, unfilled state Appearance, which dark spots (circles or the like) there in a light Environment shows where the wells are. Do this now with a bright one Liquid, for example filled with white cream, so the filling quantity and the Visually perceive the degree of wetting of the application device. This allows the the amount to be applied can be better dosed.

Different colored decorative recesses, for example, can be used for advertising purposes erhöhnen. Decorative recesses or elevations can be shaped, for example of clovers, cartoon characters or other ornaments, with either the Indentations have a different color than the surface of the raised areas, Furthermore, the individual wells or surveys can be different be colored.

The inventive applicator is illustrated by some figures below without being restricted unnecessarily by the choice of the illustrated examples want. Show it:

Fig. 1 to 4 different embodiments of the applicator body

Fig. 5 is a schematic drawing of the applicator

Fig. 6 is a schematic drawing of the storage and sealing

Fig. 7 a view from above in an exemplary fitment

In Figs. 1 to 4 are by way of example four different embodiments of the applicator body, respectively, shown here in the form of a sphere. The spherical plane ( 1 ), which can be viewed as the macroscopic surface of the sphere, and the depressions or elevations ( 2 ) in this plane are shown in each case.

In Figs. 1 to 3 wells (2) [1 Fig. And 2, different arrangements of the depressions (2)] are separate from each other before, in the form of circular hollows or in the form of square cavities [Fig. 3]. In Fig. 3, the seam line ( 3 ) is also shown, which is formed by injection molding in a two-part mold or when building the ball from two ball halves.

Fig. 4 shows a spherical application body with a system of triangular, not connected elevations ( 2 ) in the surface ( 1 ) ["closed-pore system"]. This system can also be viewed in such a way that the (in this example triangular) regions ( 2 ) represent elevations on the sphere formed by the "channel plane" ( 1 ).

Fig. 5 shows an applicator with unstructured application body ( 1 ), which is fitted into a bearing ( 4 ) such that it protrudes about half from this. The applicator can be anchored, for example, in the opening of a storage vessel ( 9 ) with an insertion sleeve ( 7 ).

In Fig. 6 is a section through an applicator which consists of a bearing (4) and an applicator body (1) is shown. The application body ( 1 ) consists of an unstructured ball, the item number ( 3 ) again refers to a manufacturing-related interface. The bearing ( 4 ) consists of a tubular fitment ( 5 ), in which the application body ( 1 ) can be inserted, and an annular support bed ( 12 ) with stabilizing struts ( 11 ) running into the ring interior [cf. see also Fig. 7]. The fitment ( 4 ) advantageously tapers upward so that the application body ( 1 ) cannot fall out.

Through the openings ( 10 ) in the support bed, the application body is wetted with the substance to be applied from the storage vessel ( 9 ) underneath, the screw thread of which is shown schematically. The applicator can be anchored in the storage vessel ( 9 ), for example, by means of an insertion sleeve ( 7 ).

The storage vessel can be closed by a lid ( 8 ), which in a favorable embodiment takes on the shape of the application body. The space ( 13 ) between the application body and the lid is then small. If the fitment ( 5 ) is made of a sufficiently flexible or soft material, the sealed storage vessel is sealed in an excellent manner in the area of the item number ( 6 ).

FIG. 7 shows a view from above into an exemplary fitment ( 4 ) in which the support bed ( 12 ) is designed in a ring shape for the application body. In this embodiment, struts ( 11 ) are attached in a star-like manner to stabilize and better hold the ball. The openings ( 10 ) allow wetting with the substance to be applied.
