  • the housing 10 is attached to the functional component 14, for example screwed, glued or welded to it.
  • the function of the paint pen is as follows:
  • the flange portion 32 sealingly abuts the valve seat surface 36, so that the fluid communication is interrupted from the liquid supply received in the interior of the bag 22 to the annular gap 42.
  • the annular gap 42 does not run completely around the applicator element 30, but is formed by four equally spaced axial grooves 50 of the applicator element 30.
  • the space between the application surface 41 and the surface 46 is supplied with liquid through these axial grooves 50.
  • the bag 22 When the liquid supply is full, the bag 22 initially largely fills the interior 18 of the hollow cylinder 12. If paint or liquid is increasingly consumed during use of the paint pen, the inner volume of the bag 22 decreases, with air flowing into the cavity 18, and the bag 22 would collapse in an undefined manner without the support element 24.
  • the trained as a support bracket in the example shown support member 24 biases the bag 22 further so that it only in the direction of the double arrows Fig. 1a can shrink and a coherent internal volume is maintained.

  • the squeegee 64 includes individual projecting teeth 66, the protruding end surfaces are formed convex or spherical and between which grooves 68 are formed.
  • the grooves 68 are supplied from the axial channel 26 with liquid or paint.
  • the applicator element 60 At its end facing away from the toothed blade 64, the applicator element 60 is provided with an annular flange 70, which can be urged by the spring 34 into sealing contact with the valve seat surface 36, which is formed on a step of the axial channel 26.
  • the radially outer peripheral portion of the annular flange 70 and the step in the axial channel 26 may be formed in any suitable manner, if only when mutual contact a seal or a secure closing of the valve formed between the annular flange 70 and the valve seat surface 36 is ensured.
  • Fig. 3a shows a view from below of the number squeegee 64 of the Fig. 3 .
  • the dental scraper is an elongated member, wherein the teeth 66 are spaced in the longitudinal direction of the component and advantageously extend over the entire transverse direction of the component. It is understood that the cross-sectional shape of the axial channel 26 is matched to the cross section of the toothed blade 64 and the applicator element 60.
  • the direction in which the squeegee 64 is moved during application of the paint is indicated by the arrow P in Fig. 3 indicated.
  • the teeth 60 are narrow transversely to the drawing direction or direction of the arrow P, preferably about 0.3 mm. As a result, they leave no traces when applying sufficiently flowable paint.
  • the spaces between the teeth or the width of the grooves 68 is also about 0.3 mm, for example.
  • the depth of the grooves 68 is for example 0.2 mm.
  • the crowned face or application surfaces 72 of the toothed blade 64 form an application plane directed obliquely to the axial direction of the end component 16 or the direction of relative movement between applicator element 60 and end component 16, in which they rest against a surface 46 to be painted to be brought.
  • This has ergonomic Advantages because the paint pen can be held at an angle.
  • the application element 60 could also be designed such that the envelope surface of the application surfaces 72 of the teeth 66 is directed perpendicular to the axial direction of the end component 16.
  • the function of the paint pen according to the Fig. 3 corresponds to that of the paint pen of Fig. 1 ,

  • the applicator element With the doctor blade used according to the invention as the applicator element a uniform coating application is achieved, wherein the application width of the elongate extent of the metering blade, which is perpendicular to the draw direction P, corresponds to a movement.
  • the painted surface can be precisely limited because of the well-defined dimensions of the sprocket.
  • the crowning of the end or application surfaces 72 of the teeth 66 advantageously ensures that the paint completely surrounds the contact point between the application surfaces 72 and the surface 46 and uniformly coats the surface 46.
  • the axial channel 26 forming an annular gap in the illustrated examples does not necessarily have to be formed around the entire shaft region 62; it is sufficient if the axial channel 26 in the drawing direction (arrow P of FIG. 3 ) lying circumferential portion of the shaft portion 62 is formed so that the teeth of the sprocket are supplied on its side facing the drawing direction with liquid or paint.
  • the axial channel forming the annular gap 42 can likewise be formed only on one side of the application element 30 facing the drawing direction, the drawing direction then being advantageously marked on the housing 10 of the paint pen.
  • the application surface pressed onto the surface to be coated does not necessarily have to be formed around the entire circumference of the application surface or when the application element is designed as a doctor blade of the application surfaces, but can only be crowned in the drawing direction or transversely to the drawing direction.
  • the pressure required to open the valve against the surface 46 to be painted is given by the force of the spring 34. This force must be so great that the valve is securely closed. When repainting or multi-layer application and high pressure required to open the valve there is a risk that a previously applied paint layer, which is dissolved by the new paint, is damaged or grooves occur that adversely affect the appearance.

  • An applicator element 96 is pivotably mounted about an axis 97 on the functional component 92. The applicator 96 terminates in a sprocket 98th
  • the application element 96 is biased counterclockwise by a spring, preferably a leaf spring 99, such that it closes the outlet opening of the axial channel 94 formed in the end face 95 when the paint pin is not in use.
  • Fig. 5a shows a view of the applicator in the direction of arrow A.
  • the pressing force or operating force of the paint pin is translated in use according to the lever arms and can be against a larger spring force to open the valve, which is formed by the applicator element 96 and the end face 95.
  • Fig. 5 construction shown can be varied varied.
  • the applicator element 96 is pressed by the spring, which is preferably designed as a leaf spring 99 in abutment against the end face 95 and when pressed against the surface to be coated 46 and pulling according to Fig. 5 to the right around their support point in accordance with Fig. 5 pivots the upper portion of the face.
  • the applicator element 96 could also be connected to the upper end region of the functional component via a film hinge designed as a membrane.
  • the paint pens described by way of example can be modified in many ways, wherein for the translation of a large valve closing force in a small pressing force of the embodiment according to Fig. 4 a design principle is advantageous in which the line of action of the contact force does not coincide with the line of action of the valve closing force.
  • the applicator element may have a plurality of toothed blades, which are arranged one behind the other in the drawing direction of the paint pen.
  • An embodiment of the paint pen such that at high valve closing force only a small pressure force of the applicator against the surface to be painted or coated is required, is also advantageous in paint pens in which the application surface of the applicator element is not provided from the outside with liquid, but for example through a central opening.
  • the Applicant therefore reserves the right to make further claims to an embodiment of the paint pen, in which the aforementioned force relationships are present regardless of the formation of the application element or its application surface.
