Definitions

  • the invention relates to a writing, painting, drawing or marking device with a housing, in the interior of which a capillary device memory for an application liquid is provided, the front end portion of which is fluidly connected to a protruding porous applicator made of fiber wick or sintered material from the housing is, wherein the housing interior opens out of the housing by means of a channel in the vicinity of the applicator, a refill space for a refill quantity of the application liquid directly adjoins the rear end section of the device memory, the refill space laterally through a peripheral side wall, in which at least one ventilation opening is provided, and is delimited on the upper or rear side by an accessible closure device, the side wall is spaced from the housing wall and the at least one ventilation opening connects the refill space to the housing interior and the Refill space is temporarily accessible from outside the case.
  • a device is known with a liquid reservoir with an upper-side adapter which receives the tip or the applicator of the device and which is equipped with a capillary tube immersed in the reservoir as a buffer.
  • This refill device is therefore for refilling a device from the front, i.e. Suitable and provided in the device memory via the applicator of the device.
  • Such a refill from the front requires a not insignificant period of time.
  • the refill container known from DE 40 27 751 C2 for refilling a writing, painting or drawing device.
  • the device is refilled via its applicator, which consists of a fiber wicking material or a sintered fiber material.
  • a writing instrument with a housing which is designed with a housing opening, an application liquid being freely absorbed in the housing.
  • the application liquid is therefore not stored in a capillary device memory provided for this purpose, but is taken up in a freely movable housing volume provided for this purpose.
  • This known device has an at least partially capillary delivery line for the application liquid, which fluidly connects said liquid volume with a writing tip, ie with the applicator of the device.
  • a capillary reservoir is connected to the delivery line.
  • a fountain pen with a holder with an ink container, with a tube spring and with a removable cap is known, for example, from DE-OS 1 937 451.
  • a closed container filled with wetting liquid is arranged in the cap and has an insertion opening adapted to the tube spring in its container bottom.
  • the tube spring of the fountain pen is enclosed in the insertion opening when the cap is in place. So here it is a fountain pen with a tube nib and not a device with a porous applicator made of fiber wick or sintered fiber material.
  • a pen nib for a writing instrument which has a writing fluid leading to an ink tip and a container with an ink chamber, which is adapted to the outer surface of the pen nib, is known from DE 34 20 287 A1.
  • a throat arrangement formed as an uninterrupted channel in the outer surface of the nib core with annular throats, the front end of which is connected to an ink suction grille connected to the ink conductor.
  • An air duct is also provided there, the front end of which is connected to an air hole and the rear end of which is connected to the rear end of the throat arrangement.
  • the air duct is formed in the outer wall of the nib core without crossing the throat arrangement.
  • This known nib centerpiece can be used, for example, in a ballpoint pen, in a felt-tip pen, in a fountain pen or in a pen for recording devices. It is also not a device with a capillary device memory for an application liquid. Rather, the application liquid is also freely movable in a receiving volume of the device.
  • a device of the type mentioned is known from DE 41 04 871 A1 (see preamble of claims 1 and 2).
  • This known device has a closure body which can be at least partially removed from the shaft end for refilling liquid application medium.
  • the end of the shaft should be closed by a closing body which is permanently attached to the shaft or integrally with it this is trained.
  • the closure body is assigned a closure body, which cooperates with this forms the closure.
  • a device is known from FR 1 313 974 which is suitable both as a marking device and as a refill container for another writing or marking device.
  • the latter writing or marking device is refilled through a ventilation opening on the front. This requires a precise combination of the two devices.
  • DE 93 11 910 U1 discloses a felt-tip pen with a housing in which a tampon made of absorbent material for storing ink is arranged and to which a separate refill device is assigned, which has a chamber filled with ink.
  • the chamber of the refill device is connected to an injection needle.
  • the housing of the felt-tip pen has an area which can be pierced by means of the injection needle and which can be an elastic insert.
  • a fountain pen which can be filled from the front, i.e. by means of a refill container. is refillable through the piston of the fountain pen.
  • the refill container is designed as a pipette that can be pierced through a membrane that is provided on the back or inside of the piston.
  • WO 92/18339 discloses a writing instrument with a device housing, a writing tip and a writing material supply store, from which the writing tip is fed directly.
  • the writing material supply is in succession via a capillary flow and connecting element with a color pigment supply and a separate one Storage for a liquid in connection, which can be conveyed through the pigment supply into the writing material supply via the connecting element and thereby dissolves and absorbs the pigment and forms the liquid writing material by mixing.
  • the necessary liquid can only be filled into the liquid reservoir and also refilled if necessary.
  • the invention has for its object to provide a writing, painting, drawing or marking device of the type mentioned that is simple in construction, very time-saving, i.e. can be refilled within a very short time, preventing contamination of the device during refilling.
  • the device memory has an outer sleeve that the circumferential side wall, which laterally delimits the refill space, inside the outer sleeve on the rear end face of the device memory and fits tightly, and that the at least one ventilation opening is formed in the vicinity of the closure device.
  • the device memory has an outer sleeve, that the sleeve-like peripheral side wall of the refill space is formed at its lower end with a radially inwardly oriented collar which is tight and tight against the outer surface of the device memory so that the Outer sleeve is formed at least on the portion projecting into the refill space with perforation holes, and that the at least one ventilation opening is formed in the vicinity of the closure device.
  • the peripheral side wall of the refill space is tight and tight against the rear end face of the device memory
  • the refill space dimension the side wall is formed at its lower end with a radially inwardly oriented collar which is tight and tight against the outer surface of the device memory.
  • the closure device can be removable from the housing of the device according to the invention, but it is expedient if the said closure device remains on the device at all times and for refilling the refill space penetrable and automatically sealed after completion of the refill process.
  • the top or rear closure device has a support base for a sealing element that can be pushed through by means of a cannula of a refill device and a rear end cap, the sealing element being arranged between the support base and the end cap and at least the support base with a through hole for the cannula of the refill device is designed.
  • a end cap which itself forms a capillary store for the stated remaining amount of the application liquid.
  • a capillary memory can be realized, for example, in that the end cap made of a suitable porous or capillary material such as a felt, a non-woven paper, a foam or the like. consists. It is preferred to produce the end cap from a dimensionally stable plastic material and to form it with a through hole that is axially aligned with the through hole in the support base and adjacent to this through hole with a capillary storage volume for the application liquid.
  • Such a design has the advantage that the remaining amount of the application liquid adhering to the cannula when the cannula of the refill device is withdrawn remains caught on the through hole of the end cap and is then immediately removed by capillary forces to the capillary storage volume adjacent to the said through hole. In this way, the end cap advantageously remains clean.
  • the closure element has, on its inside facing the sealing element, ribs running radially away from its through hole, through which a capillary storage volume for application liquid is formed. If the cannula of the refilling device is pulled out of the device again by the sealing element after the filling process has been carried out, the remaining amount of application liquid possibly remaining on the cannula is stripped off at the through hole of the closure element and moved into it by the capillary forces of the capillary storage volume adjoining this through hole . This reliably prevents contamination in the area of the through hole of the closure element with refill or application liquid and thus contamination of the device after a refill process has been carried out using simple means.
  • the inside of the closure element is formed with a circumferential collar which overlooks the ribs axially and by which the capillary storage volume is laterally limited. It is preferred if the collar is formed with a circumferential recess provided for receiving the sealing element, which is defined by a peripheral edge and a contact surface.
  • a closure element can be easily realized, for example, from a suitable plastic material in a multiple injection molding tool. The assembly of the closure element designed in this way with the sealing element is also simple and time-saving.
  • the peripheral edge of the recess is suitable on the peripheral edge of the sealing element, i.e. is adjusted with a press fit tolerance, and if the depth of the recess is smaller than the thickness of the sealing element.
  • the sealing element protrudes slightly above the closing element in the assembled state, so that the sealing element can be immovably clamped between the support base and the closing element of the closure device of the device according to the invention.
  • the radial dimensions of the peripheral edge of the recess are larger than the radial dimensions of the ribs, and if the underside of the ribs facing the sealing element and the sealing element resting on the bearing surface of the recess define a capillary gap space, because such a design enables the Capillary action for the targeted derivation of a possible remaining amount of the application liquid adhering to the cannula of the refilling device is further improved when the cannula is pulled out of the device, and thus the remaining amount is still reliably supplied to the capillary storage volume in the closure element. Since the application liquid can have volatile constituents in such devices, these volatile constituents can evaporate between successive refilling processes, so that after a corresponding period of time, an empty capillary storage volume results again in the closing element.
  • the through hole of the closing element is formed with a depression on the outside facing away from the ribs. This depression serves to center the cannula and thus for precisely positioned piercing of the sealing element, the cannula then also being pushed through the through hole in the support base and moved into the refill space so that it can be filled with the refill quantity of the application liquid within a short period of time.
  • the refill space is formed with at least one vent opening, so that the air volume displaced by the refill quantity of application liquid in the refill space can escape through said at least one ventilation opening into the housing interior, which in the vicinity of the porous, front-side applicator via at least one channel with the surroundings of the Device is fluidly connected.
  • the capillarity of the capillary storage volume for application liquid of the closure element of the closure device of the device according to the invention can be further enhanced and improved in that the surface of the capillary storage volume formed in the closure element is at least partially roughened.
  • This roughening can be achieved by an etching process or by an erosion process, with which the corresponding transfer molding tool is suitably processed to produce the closure element.
  • the sealing element arranged between the support base and the end element preferably consists of a silicone rubber material.
  • a sealing element can be used to save energy with a cannula of a refill device Refill the device are pierced, which has the advantage that the sealing element is reliably sealed by itself after pulling out the cannula.
