Patent Application
20110142891
The invention relates to a cosmetic pencil with a shaft, a reservoir present therein and filled with a liquid and a capillary application element in connection with said reservoir and arranged at one end of the pencil. With such pencils it is possible to apply cosmetic liquids to the skin, for example to the lips, with high precision. Liquids suitable for capillary application systems must be relatively low-viscosity so that the capillary cavities of the application element do not become blocked. The choice and the fraction of the constituents in the liquid are thereby severely restricted. The applications that can be achieved therewith are often not optimal and still do not have the desired appearance. In order that the application produced with the help of the application element on the skin dries quickly, the liquid in most cases comprises a high fraction of readily volatile solvents, for example of alcohols. These have the tendency to withdraw sebum and moisture from the skin, meaning that it then feels dry and becomes taut.
Proceeding from this, it is the object of the invention to propose a cosmetic pencil which provides a remedy here.
This object is achieved by a cosmetic pencil according to claim 1, the use of such a pencil according to claim 9 and by a construction kit system according to claim 10 and more specifically by a supply of a cosmetic preparation having solid, pasty, creamy or gel-like consistency being arranged at one end of the shaft. The preparation can be applied in a second step to the skin, preferably to a part of the skin provided with the liquid. In this connection, all of those substances can be applied to the area of the skin which cannot be added to the liquid to be applied using the capillary application element, whether because they would make it too thick, contain particles that block the capillary channels of the application element or have to be applied subsequently for some other reason, which is the case, for example, in the case of a powder. On account of the solid, pasty, creamy or gel-like consistency of the preparation, this is subject to virtually no limitations as regards its ingredients. Furthermore, it is advantageous that no separate application element comprising for example a small sponge or a capillary active material is used, to which the composition to be applied in a second step would have to be adapted. Moreover, an additional application element would increase the production costs of the pencil.
A preparation present in the form of a solid lead ensures particularly simple handling. The application takes place here through direct contact of the lead with skin, without, as explained above, a further application element being required. Consequently, there is more space available for accommodating the preparation. Moreover, depending on the type of application to be produced, a lead can have different consistencies. If, for application of the preparation, an application element were envisaged, this and the consistency of the particular preparation would have to be matched to one another.
In a further preferred embodiment, a supply of the cosmetic preparation in the form of a paste, a cream or a gel is provided. For this, a, for example, bowl-shaped compartment in the receptacle is envisaged which is filled with the preparation in a type of cream canister. Removed using a finger, this can be applied to an area of the skin, preferably to one to which a, for example, coloring liquid has been applied beforehand with the help of the capillary application element.
Quite generally, the cosmetic liquid can comprise substances that care for and/or color the skin, primarily the lips and the eye area. The preparation for the second application comprises, for example, substances that generate a shine and/or care substances.
The invention is now illustrated in more detail by reference to the attached drawings. These show:
A cosmetic pencil of the type according to the invention comprises a sleeve-like shaft 1, a reservoir 2 present therein for a cosmetic liquid, i.e. for a liquid that colors and/or cares for the skin, a capillary application element 4, which is in fluidic connection with the reservoir 2 and also a receptacle for a solid lead 7 arranged at the rear end 5 of the shaft 1. The receptacle is closed at its rear end by a base 8. At the front side, it leads into a tubular section 10 running coaxially to the central longitudinal axis 9 of the pencil, through which the approximately lead-shaped application element 4 travels. The application element consists, for example, of fibers extending in its longitudinal direction or of a sintered material. In the reservoir 2, preferably a capillary storage material 13 is present, which e.g. likewise consists of fibers or a sintered material. The application element 4 is protected against drying out and mechanical impairment by a closure cap 14 which can be slipped or screwed onto the front end of the stick.
In the shaft section adjoining the reservoir 2 to the back, the receptacle 6 is used in an axially fixed and preferably rotationally fixed position. Axial fixing can be brought about for example by a screw connection or—as in the case of

Finally,
The cosmetic liquid contained in the reservoir serves, for example, to color the eyelids and the eyebrows. It comprises e.g. 0.1% by weight to 5% by weight of polyvinylpyrrolidone, 4% by weight to 25% by weight of an alcohol from the group consisting of ethanol, propanol, 2% by weight to 15% by weight of a humectant, 0.1% by weight to 5% by weight of polyoxyethylene glycerol fatty acid ester and/or polyether-modified polysiloxane and a colorant, where it has, in order to enable trouble-free application using the capillary application element 4, a viscosity of less than 50 mPas (Brookfield, 25° C.).
A further example of a liquid serving the same purpose comprises 3% by weight to 35% by weight of an aqueous plastics dispersion based on acrylate copolymer with a solids content of from 30% by weight to 50% by weight, 1% by weight to 20% by weight of an alcohol from the group consisting of ethanol, propanol, 2% by weight to 15% by weight of a humectant, 0.2% by weight to 5% by weight of polyoxyethylene glycerol fatty acid ester and/or polyether-modified polysiloxane and a colorant. The viscosity corresponds to that of the first-mentioned example. Very generally, care additives such as extracts from plants, for example aloe vera, collagen, pumpkin extract, ginseng, lecithin, panthenol, caffeine and hyaluronic acid are optionally present. The liquid can also exclusively serve for skincare, in which case it then does not comprise any colorants.
A lead mass suitable for the present purpose comprises, for example, 1-20% fatty acid salt, 5-40% of a lipophilic substance with a melting range below 50° C., 50-90% solids particles and up to 10% additives.
A further example which may be mentioned is a solid lead which comprises 25-65% of a saturated branched fatty alcohol, 5-35% wax and fatty acid derivative solid at 40° C., up to 12% adipic acid and/or citric acid ester, 30% 20% pigments and 2-15% additives such as thickeners, antioxidants, preservatives, emulsifiers etc.
In order to provide an application produced with the help of the capillary application element 4 with a powder layer, a lead with a powder-like consistency is envisaged. One such lead described for example in EP 1 291 399 B1 comprises a porous lead basic body, the cavities of which are filled with a solid or liquid phase. These and the aforementioned solid leads can likewise comprise colorants and/or care substances.
