Definitions

  • the invention relates to a paint container for coloring a printing plate according to the preamble of claim 1.
  • a paint container of the type mentioned is for example by the EP 0 571 571 B1 have become known to the applicant.
  • This ink container is for inking a printing plate, also called cliché, reciprocated on this. He has at the bottom of a resting on the pressure plate edge wedge-shaped sharpened edge. When the container is filled, this pressure is applied when the pressure plate is displaced. After the ink application, the print image is transferred to a print material by means of a tampon.
  • it is essential that the container is constantly pressed resiliently against the pressure plate. This can be done with a helical compression spring. Also known is a pressing by means of magnetic force.
  • Color containers of the type mentioned are made of plastic, steel or ceramic. Especially ceramics have proven themselves. Depending on the printing plate but a paint container made of steel or plastic is more suitable. The replacement of ink containers is relatively expensive and color containers made of ceramic are relatively expensive.
  • the US 5,806,419 A discloses a paint pot in which the doctor edge is formed by a ring made of ceramic and interchangeable.
  • the ring is according to the EP 0,568,133 A held by a sealing ring.
  • a paint pot with a removable ring also shows the DE 90 06 932 U ,
  • the ring is clipped into a dovetail groove on the front of the pot and must be loosened with a special ejection tool.
  • the ring is fastened with a threaded sleeve.
  • the invention has for its object to provide a paint container of the type mentioned, which allows a simpler and less expensive pad printing.
  • the ring can be exchanged for one made of another material.
  • the pot-shaped body always remains the same. If this ring is made of ceramic, then the corresponding ink container has the advantages of a previous container made of ceramic, but the production is much cheaper, since only the ring must be made of ceramic.
  • a particularly simple assembly and a quick replacement of the ring results from the fact that it is resiliently attached to the cup-shaped body.
  • the ring is snapped onto a lower edge of the cup-shaped body.
  • the replacement is particularly simple if, according to a development of the invention, a peripheral groove is recessed on the outside of the paint container between the ring and the cup-shaped body, into which a separating tool can be inserted.
  • the lower edge of the cup-shaped body is radially resiliently formed by a recess.
  • the replaceable ring can be placed very easily and is held reliably by the elastic force of said edge.
  • the pot-shaped body can be made particularly simple and inexpensive and still results in a secure hold of the ring on this cup-shaped body.
  • the ink container 1 has a ring 12 which has a comparatively sharp doctor blade edge 13 and which is exchangeably mounted on a bottom open and cup-shaped body 3.
  • the ink container 1 according to FIG. 3 is placed thereon, wherein the doctor edge 13 rests on the upper side 18 of the printing plate 17.
  • the ink container 1 With a merely schematically indicated piston 2 or another suitable contact pressure device, the ink container 1 is pressed against the top 18 vertically.
  • a suitable color liquid, not shown here is contained, which can be refilled after removal of a closure 10 through an opening, not shown here. If the ink container 1 is moved relative to the pressure plate 17, ink is applied to the surface 18 and scraped off through the ring 12 or the edge 13.
  • the ring 12 is made of ceramic, steel or plastic, for example. Preferably, a plurality of such rings 12 are made of different materials.
  • the ring 12 can be placed in the direction of the arrow 11 of FIG. 1 on the cup-shaped body 3 and withdrawn from this again. When placing the ring 12 on the body 3 this engages a circumferential rib 8, which is arranged according to FIG. 4 at a distance from a shoulder 6. When ratcheted ring 12, this rib is below the inner edge 18 shown in FIG. 5 at an oblique inner side 19 of the ring 12 at. This inner side 19 is arranged symmetrically to a correspondingly inclined outer side 20.
  • the angle ⁇ between the two sides 19 and 20 is preferably greater than 45 degrees and is preferably about 60 degrees.
  • the ring 12 is held by an edge 7, which on the inside has a peripheral recess 14 and on the outside likewise a recess 16.
  • a region 15 is formed, on which the rib 8 is arranged and which can resiliently yield radially inwardly upon engagement of the ring 12 and during removal.
  • the ring 12 is replaced by a resilient tension of the area 15 an exact and secure fit on the body 3.
  • a further recess 21 is provided on the outside, which is arranged according to FIG. 3 on the attached ring 12 and which for removing the ring 12 allows the insertion of a suitable tool. With such a tool, the ring 12 can be withdrawn even if it is fixed comparatively firmly on the body 3.
  • the ring 12 is in particular made of ceramic.
  • the body 3, however, can be made of a relatively inexpensive metal, for example made of plain steel.
  • a set of a plurality of rings 12 is provided, which are made of different materials.
  • the ink container 1 is then provided with the ring 12, which gives the best properties with the corresponding pressure plate 17.
  • the ring 12 can be made of very high quality materials and yet the cost of manufacturing the paint pot 1 is comparatively low. If a ring 12 is damaged or the edge 13 is blurred by long use, it can easily be replaced by a new one.
