Definitions

  • the invention relates to an arrangement for forming a ventilation opening with a small cross-section, in which a closure part in one pass is inserted and the ventilation opening between the closure part and the Inner wall of the passage is formed. This applies in particular to the Ventilation opening in the ink tank of an inkjet printer ink cartridge.
  • Ventilation openings on ink tanks have a relatively small cross-section, which is of the order of about 1 mm 2 , and if possible distributed over several correspondingly smaller individual openings. It is particularly important for the quality of such ink tanks to be as constant as possible that the defined passage cross-section is maintained evenly, and in particular when producing very large quantities. In view of this, it is of crucial importance on the one hand to reproduce the ventilation openings as precisely as possible and on the other hand to produce them as economically as possible, ie with little technical effort.
  • the aforementioned bubble generator has the advantage of being relatively reliable Function. However, this requires a high-precision manufacture of the housing, namely the passage with the openings required. This is particularly true for the ball inserted in it, for which therefore a highly precise glass ball is used. A simple plastic molded part is not in this arrangement usable, which of course increases labor and costs.
  • the invention proposes starting from the features mentioned above that the closure member has a cylindrical, Plug made of elastically deformable material that can be inserted into the passage has at least one axially continuous, has groove-like indentation, and its outer diameter in relaxed Condition of the inside diameter of the passage has oversize.
  • the Particularity of the arrangement according to the invention results from the Interaction of their individual parts. That the cylindrical plug relative to the Inner diameter of the passage in the wall has oversize means namely that its outside diameter is either actually a larger one Has value as the inside diameter of the passage in the wall, or at least is at least the same size, so that an interference fit is formed, in which the plug into the passage using axial pressure can be pressed in.
  • the passage is not radial is compliant, the elastically deformable material of the plug when Pressed in deformed.
  • the elastic material could only dodge axially, it will Design according to the invention radially and in the circumferential direction in the on the Squeezed outside groove-like indentations, so that their free passage cross section reduced compared to the relaxed state becomes.
  • a particular advantage of the configuration according to the invention is that that for the first time both the wall with the passage and the closure piece in the form of the stopper according to the invention with little Manufacturing and cost expenditure bare plastic injection molded parts can be trained.
  • the passage in the wall for example of the ink tank of an ink cartridge for an inkjet printer namely simply a circular cross section without ribs or additional Deformations as in the prior art, so that they are familiar Manufacturing methods reproducibly created with sufficiently high precision can be.
  • the closure piece according to the invention d. H. the one with the In principle, the same applies to plugs provided with groove-like formations. Its cylindrical.
  • the standard form is only the one on his Modified continuous axial grooves or grooves formed on the outside, what taking into account modern plastic injection molding manufacturing methods can also be accomplished with very little effort. A Sufficiently high precision and reproducibility is also in everyone Case guaranteed.
  • the indentations have namely when the Stopper get a larger open cross-section than later for the resulting formed vents is required because the setting of this Target cross section only - as explained above - when pressed into the Passage takes place in the housing.
  • the larger open cross section at the Production of the indentations simplifies production using conventional injection molding process techniques.
  • closure piece made of plastic injection molding has opposite the prior art has the further advantage that no additional parts such Glass balls and the like have to be bought in and the manufacture is therefore easier and cheaper.
  • the configuration according to the invention also has the particular advantage that that for a given diameter of the passage in the wall through the Formation of the cross section, depth, shape and number of Indentations, the amount of oversize and the choice of elastic Material the properties of the ventilation arrangement adjustable within wide limits is and thus an optimal adaptation to the respective requirements can be done.
  • the entire closure part including the stopper is used as a plastic molding, for example made of polypropylene, as an injection molded part.
  • the groove-like indentation preferably has a V-shaped cross section. This form is well manageable in terms of production technology and in terms of Deformation when pressed into the passage to form a fine Gaps with a defined cross-section are also particularly favorable. Alternatively, you can the indentation also has a U-shaped or different cross-section to have.
  • the plug is symmetrical about its plurality Provide circumferentially distributed indentations.
  • the characteristic of the ventilation opening can by the number and cross section of the individual indentations can be influenced and optimized within wide limits.
  • An advantageous development of the invention provides that axially on the Stopper is molded onto an outflow section, which has a larger diameter has than the stopper, the groove-like indentation over the outflow section passes axially.
  • This outflow section is forming a shoulder preferably integrally attached to the plug so that it has a stop forms when the plug is pressed into the passage, d. H. from the Passage protrudes. The fact that the indentations axially over the Outflow section are pulled through, is a free inflow in the direction of the outflow section is guaranteed even if this is for example is covered.
  • a head section with a larger size is expediently located axially on the stopper Molded in one piece. This serves as a shelf limit for Pressing into the passage.
  • this head section also be formed axially on the outflow section, it being in the Diameter is at least as large as this. By doing so below the Groove-like indentations ending on the underside of the head become radially outward directed outflow openings formed, which is therefore particularly reliable because their simultaneous blocking is practically impossible.
  • the invention also includes the method of making a vent with a small cross-section in a container wall, in particular an ink tank of an ink jet printer, as detailed above explained.
  • This method uses in particular the knowledge, a simple producible indentation with a larger cross-section when pressing the Producing excess plugs in a given wall passage, the indentation while reducing the cross section to the nominal size of the Cross section of the ventilation opening is squeezed.
  • the fastening of the plug which like the wall made of a thermoplastic Plastic is made particularly easy by ultrasonic welding take place, only an ultrasonic excitation of the container wall must take place, such as when placing and ultrasonic welding already given the container wall with a container is. Because of the mass ratios of wall and stopper, they get into thereby in relative movement, whereby they are permanently welded together become.
  • the ventilation arrangement according to the invention is once in disassembled state (Fig. 1) and once in the assembled state (Fig. 2) laterally or shown in section and provided with the reference number 1 as a whole. It is formed from a closure piece 2 and a passage 3 in the Wall 4 of an otherwise not shown ink tank one Ink cartridge for an inkjet printer. As in the drawings shown, the closure piece 2 is from the inside of the container in the Passage 3 pressed.
  • the passage 3, which is shown in section, is cylindrical with defined inner diameter and smooth inner wall. He is in the wall 4 molded, which is a plastic injection molded part.
  • the closure piece 2 is also a one-piece plastic injection molded part, for example made of polypropylene. It has a cylindrical plug 5 an outflow section 6 integrally formed axially in the drawing and a head portion 7 formed thereon.
  • the head 7 has a larger one Diameter than the outflow section 6, which has a larger outer diameter than the plug has 5.
  • the plug 5 is four in total, evenly over its outer circumference distributed, axially continuous, groove-like indentations 8 provided The arrangement can be seen particularly well in the axial view according to FIG. 3. This also shows the V-shaped cross-section.
  • the plug 5 has 3 oversize to the passage,. H. its diameter has that same value or can for example be up to 0.1mm or even larger than be the inside diameter of the passage 3.
  • Both the closure piece 2, and the wall 4 with the Passage 3 are easy to manufacture plastic injection molded parts.
  • the fastening of the closure piece 2 is advantageously carried out by the entire wall is set in ultrasonic vibrations.
  • Relative movement is carried out by welding the outer circumference of the plug 5 with the inner wall of the passage 3.
