Definitions

  • the present invention relates to an ink cartridge with a circular or oval squeegee from a hard material, such as hard metal, ceramics or plastics.
  • ink cartridges Different designs of ink cartridges are known at present, some of which show a more or less complicated structure for removably mounting the squeegee.
  • ink cartridges wherein a flexible component is mounted between the component onto which a squeegee is fixed and the actual ink reservoir.
  • An object of the invention is to provide an ink cartridge which can be used as a disposable unit and which can be designed to enable the squeegees to be exchanged in an easy and technically reliable manner.
  • the ink cartridge according to the invention consists of an ink reservoir in the form of a monolithic component from non deformable material having such properties that a circular or oval channel can be provided therein for fixing said squeegee by clicking and/or by gluing to this component.
  • said non deformable material is a synthetic material, for example a polyacetal material.
  • a detail of the invention consists in that said monolithic component is internally provided with cooling ribs.
  • channels are provided in the monolithic component for circulating a cooling fluid.
  • a first embodiment of the invention is characterised by the fact that said ink reservoir comprises at the bottom two laterally extending projections which are situated diametrically to one another and onto which the required mechanical pressure can be exerted by means of a rigid and non deformable press plate.
  • said component comprises an internal hollow chamber onto the bottom of which a downwards directed mechanical pressure can be exerted.
  • Figure 1 is a cross sectional view of an ink reservoir according to the invention, in a first possible embodiment.
  • Figure 2 is a top view on the rigid, non deformable press plate to be used with such an ink reservoir.
  • Figure 3 is a cross sectional view of a variant of the invention.
  • the ink cartridge illustrated in Figures 1 and 2, consists essentially of a monolithic component 1, which forms the actual ink reservoir. At the bottom, i.e. considered in the use position, the monolithic component shows laterally two projections 2 which extend outwardly opposite to one another and onto which a downward pressure can be exerted by means of a rigid, non deformable press plate 3.
  • the press plate 3 itself receives its downward pressure from a forklike component which pertains to the printing device itself and which therefore does essentially not pertain to the currently described invention.
  • the monolithic component 1 shows a circular or oval channel adapted to the profile of the circular or oval squeegee 4.
  • the squeegee 4 can either be clicked in the channel 5 provided in the monolithic component by a snapping or clicking operation and/or be glued therein.
  • a material which shows remarkable properties for forming the monolithic component 1 is a polyacetal.
  • cooling ribs 6 are internally provided.
  • Such cooling ribs may be useful when the monolithic component, although made of a synthetic material, would be heated up as a result of a prolonged operation of the ink cartridge.
  • the structure according to this variant has been designed in such a manner that use can also be made here of polyacetal for forming the monolithic component 10 to which the squeegee 11 is fixed, considered in the use position, at the bottom.
  • the space containing the ink is indicated with reference number 12 and is in communication with the bottom space 12" through the intermediary of a narrowing 12'.
  • a chamber 13 is provided, onto the bottom of which a downward pressure can be exerted. This pressure is of course immediately transferred to the squeegee 11. Use can be made hereto of a ball 14. The means for exerting onto this ball and thus onto the ink cartridge the required downward pressure, have not been shown.
  • an ink supply duct 15 is provided which can be connected to a non shown ink supply.
  • the cylindrical wall 16, which surrounds the chamber 13, can be cooled down by a cooling fluid which circulates for example through a schematically illustrated serpentine 17.
  • the squeegee 11 can be clicked, glued or can be joined, during a spray or moulding process, to the material the monolithic component consists of, at the bottom in a circular or oval channel, provided in the wall of the monolithic component 10.
  • the ink reservoir is enclosed both at the top and at the bottom by removable sealing films or sealing plates 18 and 19, respectively. At least on the upper side, the ink cartridge is in both cases also closed off by a cover 20.
  • the choice of the material from which the monolithic component is made allows from a technical-economical point of view to consider the ink cartridge according to the invention as a disposable entity. Thanks to the properties of the synthetic material used therefor, it is just as well possible to join the squeegees 4 and 14, respectively, to the monolithic component by snapping or clicking them therein, by gluing the squeegee thereto or by uniting them in one operation during the spray or moulding process into one entity.
