Definitions
- the present invention relates to a special application device for applying an application liquid to keratinic fibers, in particular a liquid dyeing preparation, based on oxidation dye precursors.
- Human hair as an example of a keratin fiber is treated today in many ways with hair cosmetic preparations. These include, for example, the cleansing of hair with shampoos, the care and regeneration with rinses and cures and the bleaching, dyeing and shaping of the hair with dyes, tinting agents, waving agents and styling preparations. In this case, means for changing or nuancing the color of the head hair play a prominent role.
- dyeing or tinting agents which contain as coloring component so-called substantive dyes. These are dye molecules that attach directly to the hair and do not require an oxidative process to form the paint. These dyes include, for example, the henna already known from antiquity for coloring body and hair. These dyeings are usually prone to shampooing, so that sometimes after a few washes an undesirable nuance shift or even a visible "discoloration" occurs.
- oxidation colorants For permanent, intensive dyeings with corresponding fastness properties, so-called oxidation colorants are used. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components. The developer components form under the influence of oxidizing agents or of atmospheric oxygen with one another or with coupling with one or more coupler components, the actual dyes.
- the oxidation stains are characterized by excellent, long lasting staining results.
- a mixture of a larger number of oxidation dye precursors must usually be used; In many cases, direct dyes are still used for shading.
- the colorants of the three categories described in the form of creams, gels or solutions are usually applied to the fibers with the aid of a brush.
- dyes that are applied to the fibers as a shampoo formulation or conditioner formulation.
- DE 199 22 092 A1 describes, for example, a cap-like application device for dyeing hair strands, which is placed on an associated container with hair dye.
- This application device comprises a plurality of outlet openings for applying the hair dye and adjacent thereto guide prongs, which are drawn during use with combing movements through the hair.
- bristles are arranged around the outlet opening in order to achieve a more uniform application of the hair dye. Nevertheless, the outlet openings with the bristles do not allow a sufficiently metered application of the hair dye. In particular, an excessive leakage of the hair dye and thus also an unwanted wetting of the scalp can not be effectively excluded. It was therefore an object of the present invention to develop a dyeing system which makes it possible to prepare dyeing agents based on oxidation dye precursors until they are used separately and still allows easy handling by the consumer. In addition, the dyeing properties of the application device should also convince.
- a first subject of the present invention is therefore an application device for applying an application liquid to keratinic fibers, in particular hair, with at least one container for receiving the application liquid, with an application head which is connected to the at least one container and has a porous application body for applying the Application liquid by sweeping the fibers, wherein the application liquid contains the application liquid at least one oxidation dye precursor and is mixed with an oxidizing agent preparation immediately before use.

- the application body preferably has a fibrous, sponge, foam, felt or sintered material-like material structure. This material structure causes the desired capillary action of the application body, so that, for example, an unwanted leakage or dripping of the application liquid from the application body is omitted, but at the same time a reliable fluid delivery is ensured by means of the application body.
- the porous application body can also have a plurality of pin-shaped projections. This increases the effective surface area of the application body and thus improves the order of the application liquid. Accordingly, by means of the coating movement of the applicator body over the keratinic fibers, in particular the hair, a better dyeing result is guaranteed both quantitatively and qualitatively.
- the application head has a plurality of possibly detachably arranged, comb teeth. These comb teeth are arranged in particular adjacent to the application body.
- the brushing motion of the entire application head during the application initially provides, by means of the comb teeth, for a disentanglement of the fibers or the hair and thus, above all, for a uniform application of the application liquid.
- the detachable arrangement of the comb teeth on the application head allows a more versatile use of the application device. It also proves to be advantageous for such an arrangement when the comb teeth protrude from the porous applicator body.
- a preferred embodiment of the application device is to arrange the comb teeth of the application head in a circle around the application body. Regardless of the respective coating movement direction, the fibers or hair are first unraveled during use in each case before the actual application of the application liquid takes place.

- correspondingly designed storage and mixing containers are required in the context of the overall device.
- the suitably designed storage and mixing containers guarantee on the one hand prior to use sufficient storage stability for the individual components of the application liquid and on the other hand ensure appropriate handling of the overall device during use.

Mixing container and application container are identical in this variant and form the container. For both design variants is Below a variety of ways described to design such mixing container constructive.
- the first container contains the oxidizing agent
- the second container the dye composition
- the third container serves as a mixing container.
- Further additional storage containers are possible.
- To prepare the mixture the desired amount is added from the two storage containers in the mixing container, this closed and, for example, by subsequent shaking of the mixing container, the two components are mixed together.
- the mixing process can be accelerated by the fact that internals in the mixing vessel when shaking produce a turbulent flow (high Reynolds numbers) and thus improve and accelerate the mixing process.
- Another embodiment within the scope of the present invention is to provide one or more of the liquid soluble material reservoirs.
- These soluble storage containers are placed in the mixing container and there dissolved by the respective solvent, preferably a component of the mixture to be prepared.

- such soluble storage containers are designed as a foil bag.
- a further variant for producing mixtures according to the invention is the provision of at least two separate containers for storing the respective component, wherein at least one of the containers simultaneously acts as a mixing container.
- all the above examples of the variant with at least three containers are also conceivable within the scope of the present invention.
- means which provide pressure equalization between the two containers during the transfer operation.
- Such means are, for example, arranged within the opening of a reservoir tubes, which can act as a snorkel.
- one-way valves in the reservoir for pressure equalization are conceivable for such functionalities.
- closures which only opens upon a triggering command.
- the user can ensure that the transfer process does not start until the reservoir and mixing container are in the correct position for the mixing process.
- closures is, for example, a tear-open film which tears open due to an increased internal pressure in the storage container and thus starts the transfer process.
- the internal pressure in the reservoir can be increased for example by pumping means or by simply squeezing.
- the storage container for granules, powder or lumpy goods as a blister pack and additionally to provide auxiliaries which allow these blisters to be placed above the opening of the mixing container.
- the user of such mixing systems simply presses the component contained in the blister through the sealing film into the mixing container.
- An embodiment of such mixing containers can be, for example, a storage container whose destructible dividing wall can be destroyed by mechanical means mounted on the applicator head and projecting into the container. The destruction takes place in such a case by screwing or placing the applicator head in the application position.
- Separate devices for destroying the partition are of course conceivable within the scope of the present invention.
- a fixed partition with a one-way valve.
- a one-way valve could open, for example, by increasing the internal pressure in one of the two chambers and thus convert the component from one chamber into the other chamber.
- the increase in internal pressure can be achieved by the flexible design of the entire container and its compression by the user's hand. Also, additional pumping means are quite conceivable.
- a mixing device with a single container and different chambers separated by partitions, which serve as a reservoir, it may be advantageous to provide an empty mixing chamber in addition to the storage chambers before the start of the mixing process.
- an element for transferring the components from the individual storage chambers in the mixing chamber may, as already described above embodiments, destructible walls, but also one-way valves in the direction of the mixing chamber.

- the application body 31 consists in particular of a fibrous, sponge, foam, felt or sintered material-like material. The advantage of such a designed applicator body 31 is not only in the reliable promotion of the hair dye but also in the high fluid absorbency. Namely, the high liquid absorption capability prevents unwanted leakage or dripping of the hair dye from the application device 1.
- the application body 31 is preferably block-shaped (not shown) or designed with a plurality of pin-shaped projections 32.
- the embodiment with a plurality of pin-shaped projections 32 increases the effective surface of the application body 31, so that better coloring results are achieved when sweeping the hair.
- the comb teeth 33 which are likewise formed immediately adjacent to the application body 31 on the application head 3, are used for disentangling the hair during application of the application device 1. This disentangling of the hair results in a more uniform application of the color to the hair.
- the individual comb teeth 33 are integrally connected to at least one comb element 34 in order to simplify handling and production in general. Furthermore, it makes sense to attach the comb teeth 33 or comb elements 34 releasably to the application head 3, in order to permit an application without comb teeth 33 or comb elements 34, depending on the particular case of use.
- the comb teeth 33 protrude in the longitudinal direction of the application device 1 with respect to the application body 31 in order to prevent contact of the scalp with the application body 31 or the application fluid, especially in hair applications.
- the comb teeth 33 are arranged in a circle around the applicator body 31 lying around on the application head 3.
- the hair is first unraveled during the application of the application device 1, regardless of the respective coating movement direction, before the actual application of the hair dye takes place. This gives improved staining results. 2 application liquids
- the resulting colorant was mixed with percarbamide in the mixing ratio of colorant: developer 10: 1 immediately before use as described above. Subsequently, the application liquid was applied with the application device according to the invention on the fibers and rinsed after a contact time of 30 minutes.
