Definitions

  • the invention relates to a reserve bottle for an ink refill of piston fountain pens or writing implements equipped with an ink tank and an ink guide system.
  • Containers for fountain pen ink are usually shaped so that a substantially bulbous base section merges into a narrower collar section with an external thread on the upper side.
  • a closure cover can be screwed onto the collar section, which receives a sealing washer on the inside, which is pressed against the end face of the collar section in a fluid-tight manner when the screw cover is put on.
  • fountain pens of high quality in most cases are designed as so-called piston fountain pens, that is to say inside have a generally cylindrical volume of liquid that can be refilled by an externally actuated piston.
  • This volume can either be integrated into the housing of the fountain pen or be formed by a piston cartridge, a so-called converter, which is inserted into the fountain pen as a unit which can be handled separately.
  • the ink supply volume is filled by moving the piston to the foremost stop so that the internal volume of the ink supply container delimited by the piston assumes a minimum value.
  • a connection to the environment is established via the pen or the front opening of the refillable cartridge.
  • the pen or the front end of the piston cartridge is immersed or immersed in the inkwell, so that writing liquid or ink is sucked in by moving the piston back and the ink reservoir is filled.
  • the invention has for its object, in particular the students a small, handy, easily u.a. Reserve bottle for writing fluid that can be carried in school cases with a content for about two to three or even more piston holder fillings with an attachment, with which it is possible to completely empty the reserve bottle except for an insignificant remaining amount and at the same time handle the reserve bottle on the one hand and the fountain pen or the refillable cartridge, on the other hand, so that the risk of getting dirty when refilled with ink is effectively contained.
  • the tightness of the reserve bottle is to be increased both in the state closed by a lid part or a closure cap and in the docked state on a writing instrument and an education is to be created with which the filling of writing implements not provided with a suction piston with an ink tank and ink guidance system as well as Ink cartridges arranged in the writing instrument are possible.
  • a suction effect can be generated by connecting a reduced-volume, compressed refill container with the docking system to an ink supply system of a writing instrument and returning it to its original shape by releasing the refill container and thereby exerting a suction effect due to the increase in internal volume can be used in particular for cleaning emptying of the ink guidance system.
  • the particular advantage is that empty ink cartridges arranged in the fountain pen can remain in the fountain pen and can be refilled with ink.
  • the attachment will preferably be locked or welded to the refill bottle, depending on whether the attachment should be detachably connected to the refill bottle or, if necessary, as a one-piece part, e.g. can be produced by injection molding.
  • Such a connection also ensures a much better seal between the attachment and the refill container instead of a screw connection between these parts.
  • a further improvement of the seal is achieved by using ring beads or ring seals as locking means with a corresponding constriction on the opposite side, i.e. created between the attachment and / or the refill container neck.
  • the cover part has a central pin, which lies in the closed state of the reserve bottle with its jacket side sealingly against the inside of the top jacket. If the attachment has a collar which only leaves a central central opening and which lies sealingly against the bottom surface of the central pin, a large-area seal can be created at several points.
  • the cover part with its inner casing will preferably lie sealingly against the outer casing of the attachment at at least one point, preferably at two points. These points can be formed on the upper neck of the docking section on the one hand and in the region of the attachment of the attachment to the refill container in the form of an annular bulge turned outwards on the other hand.
  • a further improvement in the sealing results if the docking section has a conical cylinder jacket which, after the cover part has been slipped on, bears on both sides in a sealing manner, possibly with surface pressure.
  • the invention further includes an embodiment of the reserve bottle in such a way that it has small dimensions and is intended for a content of approximately two to three piston holder fillings. Due to its dimensions, the reserve bottle is handy, can be easily carried in student cases by students and if the reserve bottle is made of plastic, it is unbreakable. It can therefore be carried easily since the reserve bottle does not take up more space than three ink cartridges due to its dimensions.
  • the shape of the reserve bottle can be any; it is designed as a molded part or as a hollow blown body and ends in the spout with a docking lock.
  • the reserve bottle is closed with a two-piece lid. The inner part of the lid to be screwed onto the reserve bottle represents an open pipette tip.
  • an attachment is created for the reserve bottle, to which the piston fountain pen or the piston cartridge can be docked in a fluid-tight manner, wherein a latching device or snap device is advantageously provided in order to position the fountain pen or the cartridge to be refilled with respect to the attachment or the cartridge in a precise position Ensure reserve bottle. If the piston is then moved forward and air is accordingly displaced from the ink reservoir into the reserve bottle, a slight overpressure is generated in the reserve bottle.
  • the reserve bottle shown in FIGS. 1 to 5 consists of a refill container 10 made of soft, elastic plastic, preferably LDPE.
  • the refill bottle 10 has dimensions which preferably have a content of two to three piston holder fillings or other writing instrument fillings ensure that the reserve bottles can be easily accommodated in school cases.
  • the refill bottle has an external thread 11 on its neck piece, onto which a correspondingly designed internal thread of a cover part 12 can be screwed. 2 and 3, the lid part 12 can overlap both the docking section and / or the attachment as an adapter piece and, if appropriate, parts of a neck piece of the refill bottle 10 in the closed state.
  • the cover part 12 is also made of plastic, which, however, does not necessarily have to be flexible.
  • the bulbous part of the refill bottle goes over a shoulder into a neck which opens into a docking section 13, the inner jacket contour of which is designed such that a piston filler introduced according to FIG the risk of ink leakage can be rotated 180 o , as shown in Fig.4.
  • the docking section 13 can be designed both on the end section of a piston fountain pen having the nib and on the end section of a refillable ink cartridge or also of another type of writing instrument according to FIG.
  • the docking section 13 can have an upper collar which corresponds to a fluid-tight closure of the cover part 12 with an annular web of this cover part such that the annular web is placed against the upper collar of the docking section in a fluid-tight manner in the closed state.
  • the docking section can be designed to be adaptable to all piston holder diameters, for example by choosing a resilient-elastic material. If the docking section 13 is not formed in one piece with the reserve bottle 10, it can be connected via an external or internal thread with a corresponding corresponding threaded part of the Refill container or its neck are releasably connected. Here too, additional sealing lips and collar pieces, which abut one another in the closed state, can ensure increased tightness.
  • the docking section 13 can also have on its inner jacket an annular bead made of rubber-elastic material, against which the piston filler 14 is pressed in the docked state.
  • the ink tank or an ink cartridge 15 of the piston filler can be filled in the position shown in FIG. 3 or in the overhead position according to FIG. 4, the piston 16 being displaced as far as possible in the direction of the nib before being filled, and then in the opposite direction retract the plunger, drawing in ink.
  • Filling in the overhead position according to FIG. 4 has the advantage that the spring is still under liquid even when the reserve container 10 is partially empty. Filling upside down, however, requires a fluid-tight connection of the filler to the docking section.
  • rollerball pens, fine linen, fiber pens, markers and comparable devices can be considered as writing devices 18. Refilling only requires that the devices have an ink tank for writing fluid and an ink supply system with a temperature and pressure compensation system. Pad stores cannot be refilled.
  • the filling process according to Fig. 5 takes place as follows: First, the writing instrument 18 is docked on the writing side to the docking side 13 of the refill bottle 10. The device is then brought into a position in which the writing tip 19 points upwards and the reserve bottle 10 sits vertically thereon. By pressing the reserve bottle 10 several times, the writing fluid contained therein is in the tank of the writing instrument 18 pumped. Since these writing instruments 18 generally have transparent tanks, it can be easily determined when the writing instrument is filled.
  • the cover part 22 In contrast to the usual, mostly cup-shaped closure part, the cover part 22 according to FIG. 6 has a central pin 122 which, in the closed state of the reserve bottle, lies sealingly with its shell side on the inside of the cap shell.
  • this central pin 122 has a closed bottom 123 which both lies tightly against the collar 132 and closes the bottom opening 24.
  • the central pin 122 and the cover part 22 thus envelop the attachment 23 in its inner and outer area above the neck 101.
  • the central pin 122 creates an externally accessible relaxation room in which an absorbent wick 25 is located, which is on its free side from the Center pin 122 protrudes. This wick is made of absorbent material for cleaning writing utensils or the like.
  • the outer jacket 22 'of the lid part 22 and the wick 25 are closed off at the end remote from the reserve bottle 20 by a closure cap 26 which has a bore 27 through which air can enter the interior.
  • the closure cap 26 is either screwed to the attachment 22 or connected via a cam-ring-bead-groove connection 28.
  • the reserve bottle is refilled from an ink glass as follows: After unscrewing the cover part, the attachment is immersed in the ink glass and the refill bottle is pressed together. Then the refill container - the refill bottle - is released and the bottle is allowed to relax. The bottle can be removed from the ink glass with an adapter and the soiled adapter can be cleaned of the writing fluid. Finally the cap is screwed on.
  • the refilling process for a piston writing instrument or another writing instrument with a refillable ink container takes place as follows: After unscrewing the cap, the writing instrument is pressed into the attachment until it locks in the area of the ring seal 133. The writing instrument with the refilled bottle is now held vertically upwards before the piston of the writing instrument is screwed forward, whereby the air in the writing instrument is pressed into the reserve bottle 20 and an excess pressure is generated. The piston is then turned back, the ink being sucked out of the reserve bottle 20 via the leakage protection into the device via the ink guide system of the writing device. In this state, the tank of the writing instrument and the ink guide and pressure compensation system of the writing instrument are now filled.
  • the writing instrument with the docked filling bottle and the adapter can be turned over so that the writing pen points vertically downwards. If the swivel foot that moves the piston is turned by one turn to the right, two to three drops of writing fluid fall off. Then the piston is turned back by turning it to the left, whereby air is drawn from the refill bottle through the compensation system and the remaining writing fluid is removed. This also empties the compensation system, so that the writing instrument is ready for writing and resilient. Any ink or writing fluid residues can be removed with the wick 25, for which purpose the closure flap 26 is removed beforehand. Opening 27 ensures that the wick dries out again gradually.
  • the reserve bottle 300 is provided with a screw cap 301, which is formed in one piece in the embodiment shown in FIG. 7 and in two parts in the embodiment shown in FIG.
  • the two cover parts are designated 301a, 301b.
  • the docking section 226 has an external thread 230 on the outside and the screw cap or the screw cap 228 has an internal thread 232, an annular web 236 projecting from the end wall 234 for the fluid-tight closure of the attachment 210, said ring web protruding against the upper collar 238 of the docking section 226 is applied in a fluid-tight manner when the screw cap 228 is screwed on.
  • the docking section 226 is adaptable to all fountain pen diameters; for this purpose, the docking section can consist of resilient, elastic material, such as plastic.
  • a sealing lip area which, when the connector for the refillable writing fluid volume, that is, for the fountain pen tip, fits snugly against the outer circumference of the connector, preferably with a latching or at least a snap connection between the docking section 226 and the fountain pen or the one to be refilled Cartridge is done. For this reason, a sealing lip ring bead 241 is used.
  • the sealing lip area 240 or the ring bead 241 is therefore preferably adapted to the geometry of the end area of the fountain pen tip facing the spring in such a way that the sealing lips snap-fit at a predetermined point on the fountain pen or the refillable cartridge kick with a corresponding outer surface area of the fountain pen or the cartridge, so that the fountain pen or the cartridge, after docking, is positioned radially on the one hand with respect to the attachment 210 and, on the other hand, is also precisely positioned in the axial direction. It is advantageous if the docking section 226 is at least partially radially elastic, which can be controlled by a suitable choice of the material for the attachment 210.
  • the screw connection of the attachment 210 to the neck 212 of the reserve bottle 300 is fluid-tight, for which purpose an annular sealing web 242 is integrally formed on the underside of the radial constriction 224 in the exemplary embodiment shown, as shown in FIG. 10, which in increasing surface contact with the attachment of the attachment the neck 212 of the reserve bottle 300.

  • the entirety of the reserve bottle 300 with the attachment 210 and the docked fountain pen can be brought upside down (FIG. 12).
  • filling in the position shown in FIG. 9 is also possible.
  • the ink contained in the reserve bottle 300 or the residual ink still contained accordingly runs into the neck 212 of the reserve bottle 300 and accumulates there, even if only a small residual ink volume remains in the reserve bottle, up to a level P which is high enough so that the entire nib 244 is flushed with ink and submerged far enough. Due to the reduced inner diameter of the docking section 226 compared to the neck 212 and the provision of the sealing web 242, the filling height HF becomes even in this case still held high enough that only the bottom of the reserve bottle 300 should be wetted with ink (FIG. 12).
  • the preferably radially elastic design of the docking section 226 ensures that the inner wall 246 of the docking section clings to the outer surface 248 of the edge region of the fountain pen tip in a fluid-tight manner, with the sealing lips 241 being able to position the fountain pen axially with respect to the docking section 226 by the lip area behind the pointed section, ie behind the outer surface, 248 snaps.
  • the upside-down position of the ink glass 214 according to FIG. 12 only the end face 250 facing the pen 244 is wetted with ink.
  • the reserve bottle 300 After using the reserve bottle 300, it can be sealed airtight by placing the screw cap 228 or 301a on the docking section 226, so that the ink in the reserve bottle does not age if it is not in use for a long time (FIGS. 11 and 12). .
  • the embodiment according to FIG. 13 does not differ in the area of the docking section 426 or in the area of the upper collar 438 from the previously described embodiment.
  • An annular bead 441 is again provided in the sealing lip area 440 in order to form a sealing snap-in or snap connection with a connector of a piston fountain pen to be docked.
  • the peculiarity of the embodiment according to FIG. 13 is that the docking section 426 receives an adapter 460, which via the annular bead 441 can be positioned and sealed in position.
  • the adapter 460 essentially has the shape of a hollow cylinder, the diameter DI of which is slightly larger than the outer diameter DA of a refillable cartridge denoted by 462, in which a filling piston 464 is also movably received.
  • the inner surface of the adapter 460 has a sealing bead 466, which is made of elastic material and, when the refillable cartridge 462 is inserted, lies snugly and thus fluid-tightly against the outer wall of the cartridge 462.
