Description

[0001] The invention relates to a writing, makeup and / or painting system suitable for the application of highly viscous inks and designed in the form of a pen.

[0002] Pigmented inks used in pen systems, such as free-ink systems where a capillary applicator tip extends directly into an ink reservoir, or systems with a capillary reservoir and suitable applicator, generally exhibit a low viscosity of less than or equal to 10 mPas, Newtonian behavior, and a low surface tension typically less than 40 mN / m to ensure a continuous ink flow. The ink is transported by ink feeders (ink guides in free-ink systems) or directly by the applicator (tip / reservoir system). Both ink feeders and applicators are made of porous materials, and the driving force for ink transport is capillary action.

[0003] The low viscosity of these inks makes pigment stabilization a challenging task for specialists. To prevent pigments from forming agglomerates or flocculations and also from sedimenting, the pigments are often finely ground and / or stabilized with surfactants.

[0004] Nevertheless, sedimentation cannot be completely prevented if the particles have varying surface charges, densities, or particle sizes. Experts often address this by additionally using so-called gelling agents. These can be mineral-based, plant-based, or organic. This stabilizes the particles in the ink within a gel framework. The problem, however, is that the use of gelling agents increases the viscosity to such an extent that a good and continuous ink flow within a pen system is severely impaired.

[0005] Currently, only low-viscosity inks are used in pen systems. The limits of the viscosity range are around 300 mPas for the transition between low- and medium-viscosity inks, and high-viscosity inks begin at approximately 8000 mPas.

[0006] Starting from this prior art, it is an object of the present invention to provide a writing, makeup and / or painting system which is designed in the form of a pen and is suitable for the application of highly viscous preparations.

[0007] This problem is solved by the subject matter of the independent claim. The dependent claims contain advantageous further developments and embodiments of the invention.

[0008] Accordingly, the writing, makeup and / or painting system according to the invention (hereinafter referred to as "the system") comprises a preparation with structuric or thixotropic properties and an application device for the preparation.

[0009] For the purposes of the present invention, a shear-thinning preparation is understood to be a non-Newtonian preparation characterized by shear-thinning properties. A thixotropic preparation is understood to be a preparation characterized by time-dependent flow properties, wherein the viscosity of the preparation decreases as a result of continuous external influences and only returns to its initial viscosity after the stress has ceased. Thus, when a shear force is applied to the preparation used according to the invention, its viscosity decreases. As soon as the shear force is removed, the viscosity increases again, at least partially.The preparation is not limited in detail and can be designed according to the intended use, i.e., for writing, painting or makeup, whereby not only colored preparations are suitable, but also transparent or mattifying preparations can be used, for example to cover a writing or painting result or to apply mattifying and / or nourishing makeup.

[0010] The application device comprises a storage reservoir for storing the preparation, an application element for applying the preparation to a substrate, a conveying element connecting the application element and the storage reservoir, a pump and shear element arranged at least partially in a cavity of the conveying element, which is at least partially reversibly movable into the storage reservoir in the longitudinal direction of the application device between the application element and the storage reservoir, and a conveying gap formed between an inner surface of the conveying element and an outer surface of the pump and shear element for conveying the preparation from the storage reservoir to the application element.

[0011] Depending on the application area of ​​the system, the substrate onto which the preparation is applied can be paper, plastic, wood, metal and any other non-living synthetic or natural material, but also skin, mucous membrane, semi-mucous membrane or keratinous fibers.

[0012] The components or elements of the application device are arranged longitudinally in approximately the following order: storage reservoir conveying element with pump and shearing element / conveying gap conveying element.

[0013] The storage capacity is not limited in detail and is designed in the form of a container that can hold a desired quantity of preparation in its internal volume.

[0014] The pump and shear element is designed to move at least partially into the reservoir and reversibly, so that it can also be moved out of the reservoir. To stabilize its direction of movement, the pump and shear element is arranged at least partially within the cavity of the conveying element. This reversible back-and-forth movement exerts a shear force on the preparation in the reservoir, as well as a pumping action. This reduces the viscosity of the preparation due to its structural viscosity or thixotropy, making it more fluid and allowing it to be "pumped" into or through the conveying gap. This back-and-forth movement can be easily achieved by shaking the dispensing device, particularly in its longitudinal direction, in which the pump and shear element also moves, guided by the conveying element.

[0015] As already indicated above, the pump and shear element exerts a certain pumping effect on the preparation in addition to its shearing action. This pumping effect is also triggered by the reciprocating movement of the pump and shear element. This means that the movement of the pump and shear element draws or pushes the preparation into the conveying gap and forces it across the gap to the application element. The conveying gap is designed to transport the shear-diluted preparation to the application element without the preparation settling within the gap.In particular, the width of the conveying gap is designed such that, by reversibly moving the pump and shear element into the storage reservoir, an end face of the pump and shear element generates an impulse on a subset of the preparation located between the pump element and the application element at a reversal point of the movement, so that the preparation is conveyed into the application element.

[0016] For this purpose, the pump and shear element is designed such that, through the longitudinal movement of the application device described above at a temperature of 25 °C, it exerts a shear force on the preparation in the conveying gap with a shear rate in the range of 10 to 10,000, and in particular 50 to 8,000. A shear rate in the range of 10 to 10,000 is required to reduce the viscosity of the preparation sufficiently to allow it to pass through the conveying gap to the application element.

[0017] The system according to the invention is characterized in that it does not include a porous preparation conductor; that is, the preparation is not guided through or stored within pore structures for storage or application, thereby reducing or even eliminating filtration effects of the preparation. Due to the thixotropic properties of the preparation, it becomes possible to combine preparations with higher viscosity with the application device and still achieve good delivery of the preparation to a substrate with consistently high intensity via the application element. The preparation conductor is not the same as the application element.

[0018] To exert the most uniform shear rate possible from the pump and shear element onto the preparation, an advantageous embodiment provides that the pump and shear element is cylindrical. This means that at least its outer circumference, through which the shear force is transmitted to the preparation, is cylindrical.

[0019] In order to exert a shear rate on the preparation in a range of 10 / s to 10000 / s by means of a particularly moderate shaking motion of the application element and thus moderate back-and-forth movement of the pump and shear element, the pump and shear element preferably has a weight of 0.3 to 5 g.

[0020] To achieve a shear rate in the range of 10 to 10,000 cycles per second, even with small geometries of the application device, the pump and shear element is advantageously made of metal, ceramic, or thermoplastics filled with ceramic or metallic materials, and especially of metal. The term "metal" here includes both pure metal and alloys of two or more metals. Furthermore, metallic pump and shear elements have proven to be largely inert to writing, drawing, and cosmetic preparations and are also mechanically stable enough to withstand the reciprocating motion without sustaining damage.

[0021] Especially with pen-shaped systems, it is advantageous if the outer diameter of the applicator is within a range that can be easily gripped by human fingers. This, however, also requires that the internal components of the applicator be appropriately sized. Advantageously, the pump and shear element has a diameter of 2.5 to 3.5 mm, particularly 3.0 to 3.3 mm. This diameter has proven especially advantageous with a metallic pump and shear element weighing 0.3 to 5 g, as it allows for the induction of very good shear dilution in the preparation.

[0022] For good transportability of a highly viscous preparation, it is advantageous if the ratio of the width of the conveying gap to the diameter of the pump and shear element is in the range of 1 : 1 to 1 : 20.

[0023] According to a further advantageous embodiment, the width of the conveying gap is 0.1 to 3 mm, and particularly 0.1 to 2 mm. This allows various preparations of a highly viscous nature, which shear thin at a rate in the range of 10 / s to 10,000 / s, to move through the conveying gap at a consistently good speed and with stable settling. Conveying gaps with a width of less than 0.1 mm have proven disadvantageous in terms of ensuring sufficient flow of the preparation through the conveying gap. Widths of less than 0.1 mm are more difficult to pass through, even for preparations with high shear viscosity, especially if the preparations contain high proportions of solids. Conversely, conveying gaps with a width of more than 3 mm are less suitable for ensuring sufficient settling stability of the preparation.

[0024] To promote a shear rate in the range of 10 / s to 10,000 / s, it is further advantageously provided that the length of the movement path of the pump and shear element between the application element and the storage hopper in the longitudinal direction of the application device is 0.001 to 0.09 m and, in particular, 0.005 to 0.05 m. The movement path is determined from the end face of the pump and shear element facing the storage hopper to the stop (reversal point) of the pump and shear element in the storage hopper.

[0025] For particularly good application of the viscous or thixotropic preparation, it has proven especially advantageous if the application element is a capillary applicator, in particular a fiber tip, a brush, a capillary plastic (e.g., printed or extruded), a felt tip, a sponge, or a ball applicator. It is essential that the application element is designed such that any capillaries are large enough compared to the colloidal properties (according to the present invention, "colloidal particles" are understood to be particles with an average particle size of 1 nm to 1 µm) of the preparation that no active conveying by capillary action is required and the preparation can be adjusted so that its flow through the application element is slowed down at rest without any conveying impulse. If any capillaries were small, filtration effects of the preparation could occur.

[0026] To improve the portioning of the preparation for application, a further advantageous embodiment provides that the application device includes a meandering or lamellar compensating reservoir for the preparation. Excess preparation dispensed can be temporarily stored here. Suitable lamellar compensating reservoirs can, for example, include spiral or labyrinthine systems. In the event of pressure and / or temperature differences, a compensating volume can thus be provided via the compensating reservoir to buffer the storage air space. If the temperature rises, the pressure in the reservoir also rises. The emptier the reservoir, the more important the compensating volume provided by the compensating reservoir becomes.

[0027] To improve the consistent and reliable transport of the preparation from the storage tank, across the conveying gap, to the dispensing device, it is also advantageous if the conveying element includes a pressure equalization opening that connects the system's ambient air to the storage tank. This allows ambient air to enter the storage tank, preventing a negative pressure from building up over time during the conveying of the preparation, which would otherwise impede its flow.

[0028] Furthermore, the system advantageously includes a protector that at least partially surrounds the application element and seals against the conveying element. This allows a connection between the application element and the conveying element to be established. Additionally, a housing can be provided to give the user a good grip on the application device for applying the preparation.

[0029] To improve the shearing of the preparation in the storage reservoir, and thus also to more easily achieve a shear rate in the range of 10 to 10,000 s, it is advantageously provided that the storage reservoir comprises at least one mixing element and, in particular, a mixing sphere, wherein the diameter of the mixing sphere is preferably 1 to 20 mm and, in particular, less than 6.5 mm. The specific composition of the mixing element is not limited and, in particular, for the same reasons as specified for the pump and shear element, is made of metal, a metallic alloy, ceramic, or thermoplastics filled with ceramic or metallic materials. The mixing element is freely movable within the storage reservoir, while the pump and shear element moves exclusively in and out of the storage reservoir in the longitudinal direction of the application device.The mixing element thus reaches the entire volume of the storage reservoir, resulting in very thorough mixing of the preparation and consequently a particularly uniform reduction in viscosity. This not only improves the conveying properties of the preparation through the conveying gap, but also ultimately leads to improved dispensing of the preparation via the application element.

[0030] A further advantageous development provides that the preparation is viscoelastic, with a dynamic viscosity of more than 10 Pa·s and, in particular, more than 100 Pa·s at 25 °C and a shear rate of 1 / s. This results in very intensive delivery of the preparation via the application element while preventing blockage of the conveying gap by the preparation. An upper limit for the dynamic viscosity is not specifically defined, but is advantageously 200 Pa·s, which ensures good conveying stability.

[0031] Furthermore, it is advantageous if the preparation exhibits an elasticity within the linear viscoelastic range in the sense of storage modulus (G') > loss modulus (G''), which is temporarily destroyed under shear stress. The shear stress range for triggering this temporary destruction is 0.01 to 10 Pa, and the deformation range for triggering this temporary destruction is 0.1 to 100%. Storage modulus and loss modulus are measured as an amplitude sweep on a rheometer with air bearings, EC drive, activated direct strain oscillation control, and a plate-plate measuring system with a 1 mm measuring gap under logarithmically increasing load in the range of 0.01 to 100% deformation.

[0032] To improve flow properties through the conveying gap, it is further advantageous if the preparation at 25°C exhibits an elastic modulus in the range of 0.5 to 200 Pa within the linear viscoelastic range. The elastic modulus is also determined by means of an amplitude sweep on a rheometer with air bearings, EC drive, activated direct strain oscillation control, and a plate-plate measuring system with a 1 mm measuring gap under logarithmically increasing load in the range of 0.01 to 100 percent deformation.

[0033] To further improve the flow properties, the preparation preferably exhibits a yield strength at 25°C, characterized by the intersection of the storage modulus (G') and loss modulus (G'') in the shear stress range, of 0.01 to 100 Pa. The yield strength is determined by an amplitude sweep on a rheometer with air bearings, EC drive, activated direct strain oscillation control, and a plate-plate measuring system with a 1 mm measuring gap under logarithmically increasing load in the range of 0.01 to 10 percent deformation.

[0034] Furthermore, it has proven advantageous if the preparation at 25°C has a dynamic viscosity that, depending on the shear stress, encompasses the following ranges: - Shear rate 0.1 / s : maximum dynamic viscosity: 100,000 mPas and minimum dynamic viscosity: 100 mPas; - Shear rate 1 / s: maximum dynamic viscosity: 13000 Pa and minimum dynamic viscosity: 30 mPas; - Shear rate 10 / s: maximum dynamic viscosity: 500 Pa and minimum dynamic viscosity: 10 mPas; - Shear rate 1000 / s: maximum dynamic viscosity: 150 Pas and minimum dynamic viscosity: 3 Pas.

[0035] The dynamic viscosity is measured in the form of a viscosity curve on a rheometer with air bearing, EC drive, a plate-plate measuring system at a 1 mm measuring gap under a logarithmically increasing shear rate in the range of 0.1 to 1000 / s, each time in the dynamic equilibrium state of each shear rate specification.

[0036] To improve the shear-thinning or thixotropic properties of the preparation, the preparation comprises at least one gelling agent. According to the invention, a gelling agent is understood to be a mineral or organic substance that absorbs or adsorbs a solvent contained in the preparation and forms a type of gel network. Suitable mineral gelling agents include, for example, hectorite, bentonite, smectite, kaolin, or aluminum silicates. Suitable organic gelling agents include, for example, xanthan gum, alginates, cellulose ether, carrageenan, and carbomer, among which synthetic thickeners are also found.

[0037] To improve sufficient settling stability of the preparation in the storage tank even during storage over a longer period at different temperatures, the mass fraction of gelling agent in the preparation is preferably 0.1 to 3.5% by mass, in particular 0.3 to 2.5% by mass and in particular 0.5 to 1.8% by mass.

[0038] If a color imparted by the preparation is desired, it may be stipulated that the preparation includes at least one coloring substance. A coloring substance in this context refers to both pigments and dyes, which can be combined as desired to achieve the desired color result.

[0039] To improve the stability of the preparation on the substrate, it is advantageously provided that the preparation comprises at least one film-forming agent, wherein the film-forming agent is selected in particular from synthetic film-forming agents, especially polyurethane-based film-forming agents, acrylic acid-based film-forming agents, vinyl-based film-forming agents (e.g., PVP, PVA, PVAc), and any mixtures thereof. Such film-forming agents are known to those skilled in the art and can be selected accordingly.

[0040] To improve the spreadability of the preparation on the substrate, a further advantageous embodiment provides that the preparation has a surface tension in the range of 30 to 60 mN / m, particularly 35 to 50 mN / m. The surface tension is determined using a tensiometer, employing the Wilhelmy plate method, which utilizes a Wilhelmy plate. A Wilhelmy plate is a thin, usually rectangular plate made of platinum-iridium, a few centimeters in length and height. The material is selected for good wetting upon contact with the preparation. A lamella then forms, the shape or meniscus of which is determined by the interfacial tension of the preparation. The volume, and thus the weight, of the formed lamella also depends on the wetted length L of the Wilhelmy plate.Surface tension measurement using the Wilhelmy plate is performed by bringing the lower edge of the vertically suspended, rectangular platinum plate into contact with the preparation to be measured, thereby wetting it. The surface tension of the preparation can then be calculated from the force with which the plate is pulled out of the preparation.

[0041] Due to the excellent conveying properties of the applicator's conveying gap, the preparation is essentially a two-phase system in which a solid phase is dispersed within a liquid phase. Apart from this single liquid phase, no other liquid phase is present. The solid phase consists exclusively of solid particles, such as fillers, pigments, particulate conditioning agents, and the like.

[0042] To improve flow properties, the preparation advantageously comprises at least one solvent. The solvent(s) form the single-phase liquid phase of the preparation. Due to its ease of use, the solvent is preferably water and may optionally include solvents that are homogeneously miscible with water at 25 °C. Thus, the liquid phase of the preparation can consist of water and optionally solvents that are homogeneously miscible with water. Example

[0043] An example of a preparation that is part of the system according to the invention is given below. Example 1 Product name / INCI(International Nomenclature ofCosmetic Ingredients) function Concentration [mass%] Water solvent 60,53 Magnesium Aluminum Silicate Gelling agent 0,75 Pentylene Glycol solvent 2,50 Propanediol solvent 4,00 Polyglyceryl-10 Oleate surfactant 1,00 Sodium Polymethacrylate Dispersing agent 1,00 Phenylpropanol preservatives 0,60 Phenethyl Alcohol preservatives 0,40 Styrene / AcrylatesllAmmoniumMethacrylate Copolymer Film images 10,00 Sodium Hyaluronate Gelling agent 0,07 Citric Acid pH modifier 0,15 Titanium Dioxide / TitaniumDioxide 77891 pigment 11,00 kaolin Pigment / filler 3,00 Ferric ammonium ferrocyanide pigment 5,00 sum 100,00

[0044] To prepare the mixture, the solvents, the dispersant and the surfactant were mixed together, then the pigments were dispersed in it, and finally all other substances were added while mixing until homogeneity was achieved.

[0045] Fig.Figure 4 is the flow curve from Example 1, illustrating the shear-thinning behavior of the ink. At a minimum shear stress of 0.1 s -1 A viscosity of approximately 13,000 mPa·s is measured, which decreases to approximately 30 mPa·s under shear (measured at a shear rate of 1000 s). -1 ) falls off.

[0046] Fig. Figure 5 shows the storage modulus (G') and loss modulus (G'') of Example 1 as a function of shear stress, illustrating the elastic properties of the ink. The storage modulus is significantly larger than the loss modulus, and the gel structure is only temporarily disrupted at a shear stress of approximately 1 Pa, as evidenced by the convergence of the two curves.

[0047] Further details, advantages and features of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawing. It shows: Fig.1. A schematic diagram of an application device according to an initial training course, Fig. 2 a sectional view of an order processing device according to a second training course, Fig. 3 enlarged partial views from the application device Fig. 2 to illustrate the funding gap, Fig. 4 Flow curve of example 1 and Fig. 5. Illustration showing the storage modulus (G') and the loss modulus (G'') of Example 1.

[0048] The figures show only the essential aspects and elements of the present invention. All other aspects and elements have been omitted for the sake of clarity. Furthermore, identical reference numerals denote identical elements.

[0049] Fig. Figure 1 shows in detail the individual elements of an application device 1 according to a first advantageous further development, which can be assembled to form the application device 1.

[0050] The application device 1 is part of a writing, makeup and / or painting system 10 according to the invention, which, in addition to the application device 1, comprises a preparation with viscous properties contained in the application device 1. The preparation is applied to a substrate using the application device 1.

[0051] Specifically, the application device 1 comprises a storage reservoir 2 for storing the preparation, an application element 3 for applying the preparation to the substrate, a conveying element 4 connecting the application element 3 and the storage reservoir 2, and a pump and shear element 5 arranged at least partially in a cavity of the conveying element 4, which is at least partially reversibly movable into the storage reservoir 2 in the longitudinal direction L of the application device 1. The application element 3 is protected by a guard 7, which is removed during normal use to release the application element 3.

[0052] The storage reservoir 2 has an internal volume for storing the preparation, from which the preparation is dispensed. To dispense the preparation, the dispensing device 1 is preferably shaken in the longitudinal direction L. This back-and-forth movement partially and reversibly moves the pump and shear element 5, which is movably arranged in the cavity of the conveying element 4, out of the conveying element 4 and into the internal volume of the storage reservoir 2 containing the preparation.

[0053] A conveying gap 6 is formed between an inner surface of the conveying element 4 and an outer surface of the pump and shearing element 5 for conveying the preparation from the storage tank 2 to the application element 3.

[0054] The reversible back-and-forth movement of the pump and shear element 5 exerts a shear force and a pumping action on the preparation in the storage reservoir 2 such that the preparation is moved into the conveying gap 6. There, the shear force reduces its viscosity, enabling the preparation to be conveyed through the conveying gap 6 to the application element 3. For this to work, the pump and shear element 5 must be designed such that, when moved longitudinally L along the application device 1 at a temperature of 25 °C, the movement of the pump and shear element 5 exerts a shear force on the preparation in the conveying gap 6 with a shear rate in the range of 10 to 10,000 sec. This shear force ensures sufficient flowability of the preparation so that it can pass completely through the conveying gap 6 to the application element 3 and be applied to a substrate via the application element 3.

[0055] The thixotropic or shear-thinning preparation is characterized in particular by the fact that it is stabilized by one or more gelling agents, so that neither substances such as pigments or fillers separate from the preparation nor does the preparation decompose. The preparation can be designed as in the preceding example. However, the essential feature of the invention is solely its shear-thinning property, which is advantageously achieved by the addition of at least one gelling agent.

[0056] Fig. Figure 2 shows a cross-sectional view of an application device 1 according to a second embodiment. The application device 1 additionally has a meandering compensating reservoir 8 for preparation.

[0057] The conveying gap 6, located between the inner surface 12 of the conveying element 4 and the outer surface 11 of the pump and shear element 5, is particularly visible here. The width of the conveying gap 6 is, in particular, 0.1 to 3 mm. Furthermore, the conveying element 4 also includes a pressure equalization opening 9, which connects the ambient air of the system to the storage reservoir 2 and thus prevents a negative pressure in the storage reservoir 2 that would impede the conveying of the preparation to the application element 3.

[0058] Advantageously, as shown here, the ratio of the width of the conveying gap 6 to the diameter of the pump and shear element 5 is in the range of 1:1 to 1:20. The pump and shear element 5 is cylindrical and made of a metal or a metallic alloy and has a weight of 0.3 to 5 g. This allows for shearing with a shear rate in the range of 10 / s to 10,000 / s by very slight back-and-forth movement of the pump and shear element 5, so that the preparation is moved very efficiently through the conveying gap 6.

[0059] Advantageously, the diameter of the pump and shear element is 2.5 to 3.5 mm.

[0060] The application element 3 is designed in particular as a fiber tip, brush, capillary plastic, felt tip, sponge or ball applicator, so that the preparation can be applied evenly with good line thickness.

[0061] Fig.Figure 3 shows sections Y and Z from Fig. Figure 2 shows an enlarged view. Here, the conveying gap 6 is shown in detail in the front area, i.e., towards the application element 2, and in the rear area of ​​the application device 1, i.e., towards the storage hopper 2. The width B1 in the front area and the width B2 in the rear area are approximately 0.5 mm.
