Definitions

  • Fountain pens are either fed from an ink supply, which is accommodated in the hollow holder shaft and gets in there by means of a pump or suction mechanism, or from an interchangeable ink reservoir, which can be interchangeably inserted into the likewise hollow holder shaft.
  • an ink supply which is accommodated in the hollow holder shaft and gets in there by means of a pump or suction mechanism, or from an interchangeable ink reservoir, which can be interchangeably inserted into the likewise hollow holder shaft.
  • there is a system of capillary channels and chambers between the ink supply and the writing tip which ensures regulated flow of the ink with adequate supply of replacement air into the ink supply space, the two being so dependent on one another that they are more uniform, but not too strong ink flow depends on the corresponding supply of replacement air.
  • Ink guidance systems of this type have long been available in large numbers and diversity.
  • Such ink cartridges are initially sealed on all sides, on the front side either by a membrane or by a closure body inserted in an annular opening in the press fit, be it in the form of a ball or another rotationally symmetrical body.
  • the cartridge is only opened when the cartridge is placed on the cartridge receptacle located in the front part of a fountain pen, namely either the closure body is pushed into the interior of the cartridge or the membrane is cut open.
  • the cartridge body is not a functional part of the regulated ink supply to the writing tip.
  • These functional parts are located exclusively in the front part of the holder as channels and capillaries for inks and replacement air and, if necessary, as overflow chambers. It is important that the front part of the cartridge and the cartridge holder in the fountain pen match each other so precisely that complete sealing takes place, so that neither secondary air into the ink cartridge nor ink can get out of it in any other way.
  • the above-mentioned interlocking parts are designed so that they only seal at the last moment of the assembly, but the task at hand here has not been solved to install a controlled system for the replacement air between the cartridge and the cartridge holder, which is used throughout the use of the concerned ink cartridge remains fully effective and causes an even flow of ink until the last drop of ink and is easy to clean.
  • This object is achieved by the invention in a simple manner in that with a separate ink and air duct in the air duct, a control path is provided for regulating the ink delivery, the interfaces of which consist of parts of the compensating device and parts of the cartridge front part after the cartridge has been inserted in the holder is formed.
  • This controlled system through which the replacement air in the form of air bubbles has to squeeze, can be parallel-walled or conical.
  • Ring bars on the ink cartridge, on the front part of the holder or on the ink guide system can ensure that the ink cartridge is correctly seated and thus always have the same cross-section.
  • the opening membrane can be arranged offset on the ink cartridge, so that one part of this membrane is pierced, while the other part remains uninjured and forms a wall of the controlled system.
  • Figures 1 a) to 1 d) show the system according to the invention, which consists in the combination of ink cartridge / fountain pen, broken down into its components: Figure 1 a) the front part of the ink cartridge, Figure 1 b) the cartridge holder in the holder, Figure 1 c) the rear part of the ink guide * system in the front part of the holder.
  • Figures 2 a) and 2 b) show the same'examples of the invention in the assembled state in longitudinal section and in cross section.
  • Figures 3 a) to 3 c) and 4 a) and 4 b) show another embodiment of the present invention in the same representation.
  • Figure 1d is a partial view of Figure 1c
  • the outer wall (1) of the ink cartridge according to FIG. 1 a) encloses the ink supply space (2), which is closed on the front side by a membrane (3) that can be cut open and is offset so much backwards relative to the closure part (5) (4), that when inserted into the cartridge fountain pen, before the membrane (3) is opened *, while the end face of the closure part (5) remains intact.
  • the cartridge itself with its ring webs (6, 7) on the front and its groove (8), is positively inserted into corresponding forms of the cartridge holder. * is already slidably sealed by assembling nozzle 12 and inner cylinder 4
  • Figure 1 b shows the cartridge receptacle in the holder front (9) with corresponding grooves (10, 11) for the ring lands on the cartridge front part and the nozzle (12) with the help of which the membrane (3) is cut open when the ink cartridge is inserted into the cartridge receptacle.
  • the channels for ink (15) and substitute air (14) with interfaces (17) of the controlled system 16 are located on the rear part of the ink guide system (13) according to FIGS. 1c and 1d in the front part of the holder.
  • control path (16) which now consists of interfaces (17) of the cartridge receptacle or the ink guidance system on the one hand and the ink cartridge front side of the closure ( 5) is formed on the other hand.
  • FIGS. 3 a) to 3 c Another type of ink cartridge is shown in FIGS. 3 a) to 3 c), namely a cartridge which is closed centrally by means of a closure body.
  • the cartridge body (31) encloses the ink chamber (32) and is closed at the end with an annular membrane (33) which contains a receptacle (34) for the closure body (35) in the center.
  • the cartridge has beads (36) on the outside for a firm fit in the fountain pen and also ring webs (37) for engaging in an annular groove on the front part of the holder.
  • the ink guidance system in the front part of the holder (38) in turn comprises, in addition to the capillary ink duct (41), the duct for the replacement air (39) with the control path (40), which in turn is formed from parts in the front part of the holder and from the front side (33) of the ink cartridge after assembly becomes.
  • This controlled system (40) is formed from the walls (42, 43), after which the ink cartridge is finally inserted in the front part of the holder.
