PLUME FOR THE APPLICATION OF COLORING OR CORRECTING LIOUIDE DESCRIPTION OF THE INVENTION The invention relates to a pen for the application of coloring or correction liquid, with an outlet opening for the cuff part that presents the coloring liquid, a valve, which at least it includes a spring and a guide element, and a sphere coordinated to the outlet opening that serves as an applicator element. Under the term liquid colorante or corrector that from here on will be summarized in coloring liquid, they are to be understood not only coloring liquids but also correction liquids without coloring pigments. In suppliers of glues or paste applicator apparatuses it is known (see DE 10 01 624B or US 2 984 393 A) to apply a bar which serves as a valve member through a spring formed therein in the closed position, where it closes the exit opening of the supplier or apparatus. That supplying apparatus or applicator is only appropriate for a relatively wide inaccurate application of the material contained therein. On the contrary, it would be desirable in the application of coloring liquids or correctors an exact application, easy to trace and, if necessary, a thin line. A glue supplier has already been proposed to see
REF: 27186 (EP 331 843 A) in which a sphere serves as applicator element and valve member. This sphere receives action directly from a spring element, such as a spring spring or a spiral spring. However, the spring element can not stop or stop correctly in the application of glue, to the sphere if it is pressed back from the exit opening, as far as lateral movements are concerned. With this only an application of relatively inexact material becomes possible, which precisely in the suppliers of glues could happen, but not in the application of coloring liquids or correction fluid. This also applies to a supplying mechanism with a spring-driven sphere placed in a bottle cap according to US 1 378 016 A. In order to obtain in pens for the application of dyes for writing or correcting, especially for the application of correction fluid, for an exact application, a good mobility of the colorant applicator tip is required, by placing a sphere mounted rotatably in a sleeve part. For colors that are low in viscosity and that dry quickly, it is also important that an exit of the dye and / or the solvent is only possible during the application process of the dye. For this a solution according to EP 564 410 Al is provided (comparable solutions are presented in FR 2 665 649 A, FR 461 361 A, FR 329 628 and DE 43 04 910 A) having a sphere as an application element which it has a guide or transmission element in the form of a bar which is pressed against the sphere by a spiral spring, from the inside of the sleeve to the edge of the outlet opening. To apply on a paper, in a desired place, liquid coloring, the pen with the sphere - which may have a small diameter - is pressed against that place and if necessary moves on the paper, so that the sphere is pressed against the force of the spring, retracting from the outlet opening and the dye may come out. The spring, the bar, the sphere and the sleeve thus form a valve, which is closed when the tip of the pen is unloaded and undesirable running and / or drying of the coloring liquid is impeded. The guide element formed by the bar stops and drives the sphere in the area between the closing and opening positions. Spiral or helical metal springs are used for the necessary spring properties. These springs must be mounted on the guide element and on the boom itself with a support bracket. To be mounted on the boom, it is put into the sleeve after the ball and guide element are mounted., a mounting part. To achieve the desired valve qualities, the two supports or mounts must be at an exact distance and the spring must have the proper springing properties. Known pens have the disadvantage that the different small parts, of which at least the spring is metallic, must be exactly accommodated. The coil springs in themselves are short and can therefore only be misplaced and badly stopped. The guide element the sleeve and the support part are preferably made of synthetic material. Since the separation of the metallic spiral spring from the other parts by reason of the care is complicated, such feathers represent an undesirable fault formed of two components. The invention proposes the task of constructing dye applicator pens of that species with a sphere as a dye applicator element and a guide element, so that its manufacturing and assembly process becomes simple, in addition the removal should be simplified, and with this, no less, a precise fine application of the coloring or correction fluid must be carried out, as well as ensuring a safe closing of the valve. The pen according to the invention of the aforementioned type is characterized in that the spring means at least comprises a leaf spring, optionally a leaf spring or a cut of a leaf spring. the solution according to the present invention provides that the spring required for the valve comprises at least one leaf spring, thus an elongated spring element, especially running in the direction of the guide element, bendable under the effect of the force transversely to its longitudinal direction or that I varied its conformation. In the deformation, the shape of the individual turns will not be altered in the essential and only the distance between the turns will vary, contrary to what happens with a spiral spring. The leaf spring provided according to the invention has, compared to a coiled or helical spring with comparable elastic properties, a greater length, but needs less cross-section in the cross-section. This is advantageous for placement in an internal sleeve space, because the elongated shape d facilitates the stopping in the positioning or in the accommodation, and the small cross section does not influence the flow through the coloring liquid. In the dye-applicator penstock valve, the elastic effect of the easy folding leaf springs is applied essentially along its longitudinal direction. With this, for example, one end of the leaf spring is connected to the conductive or guiding sleeve of the dye and the other end is joined to the guide element placed on the sleeve or kept in contact but free to move. In a displacement of the guide element generated by the pressure on the sphere on an underlying layer in the sleeve, the elongate elastic element will deform by increasing its cross section and thus shortening in its longitudinal direction. The force resulting from the elastic deformation in the direction of the guide element closes the valve and thereby seals the outlet opening, if the tip of the pen is not already pressed against the underlying surface. Since the guide element is arranged rather centrally in the sleeve and also by its displaceable displacement by the elastic agent essentially along its longitudinal axis it must not come into contact with the sleeve, at least two are arranged, the case also three or four springs of sheets essentially symmetrical to the longitudinal axis of the guide element. If now a multiplicity of springs of equal leaves are guided around the guide element from this towards the sleeve, they will produce a bell-shaped structure, which essentially corresponds to a plate spring. It is therefore understandable that the plate springs or sections thereof in a broad sense are considered as leaf springs and can be used within the scope of the invention. The leaf or plate springs used can be made of synthetic material, so that especially if the sphere of the applicator element is also made of synthetic material, the pen of a single material is produced. Such pen or applicator of a single component, can after use be conducted without separation problems to a recycling. However, it also has no problem to provide a metallic sphere, since it is in contrast to the fixedly collapsible metallic spiral springs, when removing the internal parts of such a feather it will fall from the arrest offered by the shape of the exit opening and will easily be able to take off. If the spring agent and the guide element are modeled in synthetic material, then there is a possibility of constructing these two parts in one piece. According to a preferred embodiment, the spring means comprises a connection part which is connectable to the sleeve part, which can preferably be fitted therein. The spring or elastic means is thus connected to the connection part on the one hand and, on the other hand, to the guide element. The interconnected parts can be easily fabricated as a dependent injection casting part and with a minimum of expense placed on the sleeve. Here the elastic properties will depend only on the manufacture not on the assembly. In order to prevent the applicator sphere or element from being moved too far into the sleeve portion during the application of the dye or correction fluid, it will also be advantageous if the guide element has a stop surface, whereby it will be delivered. to a limitation of its displacement against the spring force of the spring in the direction away from the outlet opening, reaching an opening stop in the apparatus. Here it will be advantageous for a termination or assembly that the opening stop is connected with the spring , especially with a connecting part of the spring fixable in the sleeve part, where the guide element is connected in a first end region of the spring and the opening stop does it in a second end region of the spring. For the desired spring effect and a simultaneous reach of a guide function, it has also been found advantageous that the spring at least consists of a leaf spring with a bent section, especially in the form of an S or U, which with the movement of the Guide element away from the outlet opening is deformed in such a way that a recoil force is produced. In view of being able to make a thin line application with relatively strongly inclined feathers, it is also advantageous if between the sphere serving as the application element and the gliding element is provided at least one other sphere, where this other sphere or at least other The spheres of the guide element can be placed under the effect of the spring means against a closing stop of the sleeve part. In this way the sphere-application element can be provided small and with a weak retention, since the closing forces of the other or of the other spheres will be taken and transmitted. In particular, it is possible that the sphere serving as the application element for the other sphere disposed in the closing stop, in essence, is transportable to the closing contact with the outlet opening, free of pressure. It is also advantageous here that the diameter of the sphere serving as the applicator element is smaller than the diameter of the other or other spheres. Finally, it is favorable that the other sphere be put into rotation by the rotation movements of the sphere that serves as an applicator element, and that by the movement of rotation of the other sphere an effect or impulsion of the coloring liquid is reached in an intermediate space arranged between the two spheres. In the following, the present invention will be explained in more detail by means of embodiments in reference to the drawings, which are merely illustrative and not limiting. Sample: Figure 1 a cut through an application tip of a pen with a sphere and a guide element, which is joined by two leaf springs with a connecting part; Figure 2 a detail of a cut through a tip of application of the feather with leaf springs weakly folded; Figure 3 a section through the applicator tip of a pen similar to that of Figure 1, but now with two spheres, according to an especially preferred embodiment, considered at the time as the best embodiment, and with a guide element, which is joined by two leaf springs with a connecting part; Figure 4 a section through the end region of a tip of that type of application with two spheres on an enlarged scale with respect to the representation of Figure 3; Figure 5 a section through the end area of an application tip similar to figure 2, but now with three spheres; Figure 1 shows a sleeve part 1 of the pen tip of a pen for the application of coloring liquid. The sleeve part 1 encloses a colorant space 2 and has an outlet opening 3 for the coloring liquid at one outlet end. To feed the colorant space 2 with dye liquid, a connection opening 12 is provided. The connection opening 12 is surrounded by a connection region, in particular a thread 13, so that the sleeve part 1 is connectable to a container of coloring. In the outlet opening 3, an application sphere 5 is pressed from the dye space 2 by means of a rod-shaped guide element 4. The guide element 4 is pressed against the outlet opening 3 by less a leaf spring, in the present example of two, possibly also several, leaf springs 6 arranged substantially symmetrically with respect to an axis 4a of the guide element 4. Thus is the first end region 6a of the leaf springs 6 next to the guide element 4 displacement-free, or preferably connected therewith. In the present exemplary embodiment, for connection of the end region 6b of the leaf springs 6 as the sleeve part 1, a connecting part 7, which is in particular ring-shaped, which is seated in an adherent seat in the upper part of the sleeve part 6, is provided. sleeve 1. An internal engagement limitation 8a in the form of a shoulder and an outer flange 8b limit the adhesion seat in the sleeve part 1. The connecting part 7 has a central guiding area 7a for the guiding element 4. This guiding area 7a is formed according to Figure 1 of projections 9 directed radially inwardly. Between the projections 9 there is provided an area of flow passage opening large enough for the coloring liquid. The leaf springs 6 shown are preferably made of plastic and S-shaped, with two opposing areas of curvature. In the movement of the guide element 4 away from the outlet opening 3 at least the radius of curvature of one of the areas of curvature decreases. This elastic deformation causes a corresponding recovery force. The protrusions or extensions 9 of the connecting part 7 additionally have the function of a guide (or, as the case may be, the function thereof) to limit the movement of the connecting element. guide 4 moving away from the outlet opening 3. With this object, the guide element 4 has a stop surface 10 in the form of a joint that rises radially outwards, which in the maximum displacement of the guide element 4 rests on the lower side of the extension 9, whereby they define an opening stop 11. In fact, such an opening stop 11 can also be connected, in particular, to the projections 9 with the sleeve part 1 and / or the part of the latter. connection 7. The length of the opening stop 11 is selected in such a way that the application element sphere 5 always protrudes sufficiently from the outlet opening 3 to ensure the application of the colorant. and. It is understood by itself that the conformation, number and arrangement of leaf springs 6 can be chosen according to the existing need. If necessary, the guide element 4 is driven sufficiently through the leaf springs 6., so that there is no guide zone 7a. The opening stop 11 is especially necessary if the application element sphere 5 does not have to be pressed completely into the sleeve part 1. If for certain applications it is not important that a strong pressure of the tip of the pen against the lower support of the edge of the outlet opening 3, in the lower support, then the opening stop 11 is not necessary. If necessary, it can also be caused by means of a sufficiently large spring force of the leaf springs , that the sphere of application 5 also with a normal pressure of writing protrudes something outwards and in this way remains rodable. Fig. 2 shows an embodiment, wherein the leaf springs 6 'only join regions of curvature weakly stamped to the guide element 4 with the connecting part 7. The shape of a preferred leaf spring must be such in the closed position (with the outlet opening 3 closed), the first end region 6a of the leaf spring 6 is movable away from the opening 3, and the displacement of the end region 6a leads to the deformation of the leaf spring 6 thus generating a recoil or recovery force. With this the leaf springs can be constructed differently. If necessary, leaf springs, which run more or less radially and thus not along the guide element 4, can be provided. In this mode, the guide element 4 will be slightly displaceable with respect to the axis, so that it can be dispensed with. a guide region and an opening stop. The guide zone and the stop area for the guide element 4 can also be constructed in accordance with Figure 2 as a ring 14 running around the guide element 4. To join the ring 14 with the connecting part 7 they will be provided radial connections 15 in the form of spokes. for the formation of an opening stop is the stop surface 10 of the guide element 4 coordinated to an opposite lateral surface 14a of the ring 14. Since the radial connections 15 and the ring 15 are constructed narrow, the free cross section of dye space 2 will only be a little smaller. The formation of leaf springs 6 'only impedes the flow of the coloring liquid through dye space 2 only in an insignificant manner. Figure 3 shows a pen tip of a pen for applying a coloring liquid, which is essentially constructed corresponding to the pen tip of Figure 1. The structure according to Figure 3 and in an enlarged representation according to Figure 4, encompasses a second sphere 16, which is disposed between the sphere-application element 5c and the end to this opposite of the guide element 4. Inside the sleeve part 1 there is provided for the second sphere 16 a tight closing seat or a closing stop 17, so that the second sphere 16 pressed by the element of guide 4 against the seat 17, hermetically sealing the dyeing space 2. By means of the second sphere 16 resting on the closing stop 17, the sphere of application 5c is kept essentially free of pressure in accordance with the act of closing with the exit opening 3. In the pens presented, a valve is provided very generally in the area of the tip of the pen, which only allows the exit of the coloring liquid, when the tip of the pen or applicator it is pressed against a lower support, or when the application sphere 5, 5c, is pressed somewhat against the dye space 2. The valve comprises at least one spring means 6, 6 'and a guide element 4. The exit closure it is achieved by means of a closing contact between at least one area or region of the inner edge of the sleeve part and the guide element and / or at least one sphere. In the embodiment according to the
Figure 1 serves the sphere-application element 5 as closure element, and rests in the closed position from the inside against the outlet opening 3. To prevent the exit of this application sphere 5, it must from the edge of the opening outlet 3 must be constructed sufficiently solid and with enough tightening or peripheral closing of the application area 5. This leads to the application area only slightly protruding over the relatively wide edge of the outlet opening 3 and the inclination of the pen , in which the valve by a pressure against the lower support can no longer be opened or where the application of dye is no longer possible, is relatively small. In the application form according to FIG. 3, the second sphere 16 serves as the closing element, which transfers the closing force of the valve to the closing seat 17. This also gives the possibility of providing a compact embodiment valve. Also the sphere of application 5c must not be stopped so that it can receive closing forces. In this way the edge of the thin outlet opening 3 and the application sphere 5c can be constructed only slightly more than half will be surrounded. The boom can thus be inclined around a large opening angle 19 (Figure 4) up to 70, but which for reasons of stability will be between 25a and 45, being up to the edge of the exit opening, when resting on the surface lower and prevent pressing the valve. In a movement of the pen tip pressed on the lower surface the application sphere 5c rolls on the lower surface, and with this the sphere 16 which is in contact with it in pressure will rotationally move. By the rotational movement of the second sphere 16 a good creative effect is attainable, that is a transport of the coloring liquid from the dye space 2 to an intermediate space 18 disposed between the two dials 5c, 16. By means of this arrangement by a part only as much dye mass will be applied as is really necessary, and on the other hand a sticking or adhering of the sphere of application 5c will be avoided. The diameter of the first sphere 5c is -correspondingly to the construction of the hollow space of the sleeve in the area of the outlet opening- somewhat less than the diameter of the second sphere 16. Figure 5 shows another possibility of the application of dye for the sphere of application 5d. For this purpose, there are two other spheres 16a, 16b, which, on the one hand, take charge of the transport of the coloring liquid and, on the other hand, act as closing elements. The diameter of these two spheres 16a, 16b will be different if necessary. to the internal mass of the hollow space of the sleeve; in the hollow space of the sleeve that widens towards the dye space 2, the diameters of those domains 16a, 16b are also selected. If necessary, they could increase the amount of colorant application, arrange several spheres in a plane above the sphere of application, possibly three spheres. An arrangement of that type would then be in the form of a tetrahedron, where the tip of the tetrahedron would be formed by the sphere of application. It would be interesting in the form of an example for the ballpoint pen or lacquer pen that it could present embodiments, which had at least two of the spheres disposed in the exit opening 3, and which, if appropriate, encompass other or none of the previously described shapes of a spring means. It is understood that all the features of the described embodiments can be combined at will. Thus, for example, other spheres 16 or 16a, 16b can also be provided in a boom with leaf springs 6 * according to Figure 2, and / or a ring 14 provided in spokes 15, in a boom according to the Figure 1 (or Figure 3).
