Definitions

  • the invention relates to a device for refilling a writing, drawing or painting device, the device comprising a capillary-promoting application element protruding from a housing, a storage chamber connected to the application element, which contains a capillary memory for holding writing fluid, and one adjacent to the application element Has air supply channel and the device consists of a container which has a storage space for the writing liquid to be refilled, a wall area movable into the storage space and a neck portion which is connected to the storage space, can be closed by a closure element and is designed such that at open neck section, the writing instrument to be refilled with its application member and with a housing section adjoining the application member can be inserted therein and the neck section can be sealed by the housing section.
  • a device of the type specified is known from DE-GM 90 16 777.
  • the known refill container consists of a tube-shaped storage space for the refill liquid, the neck portion of which is closed by a closure element when not in use.
  • the closure element is removed and the writing instrument to be refilled with its application element inserted into the neck section of the refill container until the neck section is sealed.
  • the writing instrument and refill container are then brought into the refill position, ie into a position in which the refill container is located above the application element pointing upwards.
  • a pumping effect is achieved, by means of which the refill liquid is conveyed into the storage space of the writing instrument via the application member and the air supply duct running along it.
  • the writing fluid is generally stored in a capillary memory in the writing instrument. If, as in most cases, the degree of filling of the capillary memory cannot be seen from the outside of the writing instrument, there is a risk of overfilling if the liquid is refilled too early or too much.
  • the excess liquid which can no longer be absorbed by the capillary reservoir, remains in the lower end of the storage chamber of the writing instrument in the refill position and in the area of the air supply duct along the application member. This has the consequence that the writing instrument drips in the writing position, since the liquid runs outwards along the application element.
  • the dripping and blotting of the writing instrument is intensified if the writing instrument is heated by hand warmth or lying in the sun. As a result of the heating, the air contained in the storage chamber expands, which can lead to both free ink located in the storage chamber and ink from the capillary memory being pressed outward along the application element.
  • a device for filling liquid into a storage space for example a fountain pen
  • the known device consists of a bottle-shaped container for storing liquid.
  • a container head with an upwardly open recess is inserted, into which a riser pipe protruding into the container opens.
  • the bottom of the container or the upper end of the container adjacent to the container head is designed as a flexible membrane.
  • This pressure deforms the flexible membrane of the container, creating a pressure in the container through which the liquid is conveyed via the riser pipe into the container head and from there into the reservoir of the fountain pen, the pressure in the fountain pen opening the valve.
  • the container head can additionally contain a check valve opening into the container, which is opened by the vacuum that is created in the container when the membrane returns to its starting position, so that unnecessary liquid can flow back into the container from the recess in the container head.
  • This known container is not suitable for filling a writing instrument via the air duct of the writing instrument adjacent to the application element.
  • liquid is inadvertently pressed out of the container via the riser pipe and can spray out if a pressure which is higher than atmospheric pressure occurs in the container as a result of temperature or air pressure fluctuations.
  • the object of the invention is to provide a device of the type mentioned, with which a simple and quick refilling of a writing, drawing or painting device is possible without overfilling the pantry and the associated disadvantages and that Device can be opened without inadvertently writing fluid can escape.
  • the object is achieved in that the neck section is separated from the storage space by a partition and in that one end of a riser pipe opens into the neck section, the other end of which is connected to the storage space near the bottom, that the storage space of the container has a vent hole which opens into the neck portion and that means are provided by which the vent hole is closed during the refilling process.
  • a writing instrument can be refilled in a simple manner and within a short time, without overfilling occurring.
  • the refill is inserted into the neck section of the container from above for refilling in the writing position, ie with its applicator element pointing downwards. Pressing on the movable wall area of the container and an associated reduction in the container volume increases writing fluid in the container of gravity through the riser pipe into the neck section separated from the storage space. From there, the writing fluid is pressed via the applicator and the air supply duct running along it into the storage chamber of the writing instrument, where it is taken up by the capillary memory until the capacity of the capillary memory is exhausted.
  • vent hole enables a pressure in the storage space which is higher than the atmospheric pressure, which can occur when the container is closed due to temperature or air pressure fluctuations, to degrade parallel to the riser when the closure element is opened. This prevents writing fluid from being pushed up through the riser pipe and opening unintentionally as a result of such overpressure in the container when it is opened.
  • the vent hole is closed so that the writing fluid can be pumped up through the riser pipe.
  • the vent hole can be closed in a particularly simple and inexpensive manner in that the vent hole is closed by a housing section of the writing instrument when it is inserted into the neck section.
  • the neck section is surrounded by the storage space and in that the vent hole radially penetrates the neck section, annular seals being provided on both sides of the vent hole, with which the housing section of the writing instrument can be sealed in the neck section.
  • the vent hole can also be closed according to the invention by a spring-loaded valve in the closing direction, which is held in the open position by the closure element and closes when the closure element is removed by spring force.
  • the riser pipe opens into an opening in the partition.
  • the riser pipe is located directly below the inserted application element of the writing instrument.
  • the partition can be provided on the side facing the neck section with a funnel-shaped depression, the deepest point of which is the mouth of the riser pipe.
  • the inner contour of the neck section is adapted to the outer contour of the part of the writing instrument to be inserted into the neck section in such a way that only a small space remains.
  • Figure 1 shows a device for refilling with a container 1 made of a flexible plastic material, for example polyethylene, which is bottle-shaped and whose storage space 2 is filled with a marking liquid 3.
  • the volume of the container 1 is dimensioned such that the filled amount of marking liquid 3 is sufficient for several refilling processes.
  • the amount of marking liquid 3 required for each refilling process is indicated by marks on the container 1 in the form of dashes.
  • a neck section 5 with a bore 4 and an annular channel 41 is provided at the upper end of the container.
  • the bore 4 is separated from the storage space 2 by a partition 6.
  • one end 8 of a riser pipe 9 opens, the other end 10 of which is located at a short distance above the bottom 11 of the container 1.
  • the riser pipe 9 connects the storage space 2 with the bore 4 in the neck section 5.
  • the annular channel 41 is connected to the storage space 2 through an opening 71 in the partition 6, whereby pressure equalization between the storage space 2 and the bore 4 is made possible.
  • the neck section 5 can be closed with a cover (not shown) when not in use.
  • a marking pen 12 with the writing tip of its wick 13 and a housing section 14 adjoining the wick 13 is inserted into the bore 4 of the neck section 5 from above.
  • a capillary reservoir 16 is arranged in a storage chamber 15 of the marking pen 12 and supplies the wick 13 with marking liquid 3.
  • the capillary storage 16 does not completely fill the storage chamber, so that open cavities 17, 18 remain in the storage chamber 15.
  • the cavities 17 surround the inner part of the wick 13.
  • the cavity 18 is located between the capillary memory 16 and the wall surface of the housing section 19 of the marking pen 12.
  • an air channel 20 is provided which connects the storage chamber 15 with the bore 4 of the Neck section 5 connects.
  • the storage space 2 of the container 1 is emptied after repeated refilling, it can, although it is tightly closed, be refilled with marking liquid.
  • the container 1 with the Neck section 5 is immersed down into a liquid supply and new liquid is sucked in through the riser pipe 9 by repeated compression.
  • the lid is removed from the neck section 5 of the container 1. Then the marker pen 12 is in the writing position, i.e. with the tip of its wick 13 pointing downwards, as far as it is inserted into the bore 4 of the neck section 5, until the housing section 14 of the marking pen 12 bears against a sealing bead 21 which runs around the inner wall of the neck section 5, so that the bore 4 is sealed.
  • a second sealing bead 51 seals the annular channel 41 on the housing section 14.
  • the marking liquid 3 By pressing the flexible wall 22 of the container 1, its volume is reduced and the marking liquid 3 is pressed against gravity via the riser pipe 9 into the neck section 5 and from there via the wick 13 and the air duct 20 into the storage chamber 15 of the marking pen 12. where the marking liquid 3 is at least partially absorbed by the capillary reservoir 16. If more marking liquid 3 is pressed into the storage chamber 15 than can be taken up by the capillary storage 16, then it collects in the cavities 17 due to the force of gravity. In the event of an even greater overfill, the cavity 18 also fills with excess marking liquid 3.
  • the pressure on the wall of the container 1 is reduced when the button is released. This increases the volume in container 1 again.
  • the air compressed when filling the marking liquid 3 into the storage chamber 15 of the marking pen 12 can relax and the part of the marking liquid 3 not bound by the capillary reservoir 16 can be released via the Press air duct 20 back into bore 4 of neck section 5. From there, this part of the marking liquid 3 is sucked back into the storage space 15 of the container 1 via the riser pipe 9, so that no free liquid remains in the storage space 15
  • FIG. 2 shows another embodiment of a device for refilling with a likewise bottle-shaped, flexible container 23 with a constricted neck 24, in which a plate 25 is inserted tightly.
  • a cup-shaped neck section 27 Arranged in a central opening of the plate 25 is a cup-shaped neck section 27, which projects into the storage space 26 of the container 23 and has an opening in its base 28 in which a riser pipe 29 is tightly fastened.
  • the cylindrical part of the neck section 27 has a vent hole 30, which connects the storage space 26 with the hole 31 of the neck section 27.
  • annular sealing lips 32 are formed in the hole 31, which tightly encompass the housing section 33 of the marking pen 34 inserted into the hole 31.
  • vent hole 30 is closed by the housing section 33 during the refilling process in order to enable refilling, as described above.
  • the vent hole ensures pressure equalization on both sides of the riser pipe and thus prevents an undesired escape of marking liquid when opening a cover, not shown, which closes the neck 24.
