  1. The present invention relates to a felt type writing instrument, and more particularly, to a writing instrument having a felt tip which receives a material in the liquid state such as ink and the like so as to be saturated, this material being supplied between a container incorporated in the instrument and the upper end of the point, instrument characterized in that:

  an elongated ink guide hole is provided in the former

  upper end of the point, the depth of which reaches

  the middle part of the height of the point, a hole which

  receives material in a liquid state such as ink from

  from the container. In the prior art, the tip of a conventional writing instrument of the felt type does not include

  not the ink guide hole just mentioned.

  It follows that a writing instrument classi-

  that has the disadvantage of requiring relatively time

  important for its tip to be saturated with liquid medium

  such as ink, and the amount of liquid reached

  gnant the tip is weak; it also has the disadvantage of not giving an impression of regular writing, because

81932

2.

  there is a big difference in the amount of ink ne-

  stop at the cutting edge between fast writing and writing

slow ture.

  It is an object of the present invention to eliminate the above drawbacks by providing an elongated ink guide hole in the upper end surface of a felt tip of a writing instrument, the depth of which reaches the middle part. from the height of

The point.

  More specifically, an object of the present invention

  tion is a felt-like writing instrument, the

  tip receives a liquid material such as

  cre and the like to be saturated, material that is supplied

  neither between the container incorporated in the instrument and the ex-

  upper tip end, instrument characterized in that: an elongated ink guide hole is provided

  in the upper end of the point, a hole the pro-

  cross-country skier reaches the middle of the height of the point

  te and which receives the material in the liquid state such as ink

  and the like provided by the container incorporated in the ins-

  are plowing. The present invention will be well understood during the

  following description made in conjunction with the drawings below

  seals in which: Figure 1 is a longitudinal sectional view of the felt type writing instrument of the present invention; Figure 2 is an exploded perspective view of the instrument; Figure 3 is a sectional view taken along line A-A of Figure 1; Figure 4 is a sectional view of the writing instrument at the time when a pressing action has just been completed; Figure 5 is a longitudinal sectional view

  of the instrument in case the insertion is complete

  loosely released; Figure 6 is a longitudinal sectional view of the instrument in the case where the insertion is stopped halfway.

  In the embodiment of the present invention

  tion, a mouthpiece 4 is made of hard plastic material and has a thick part 1 and a thin part 2 both in the form of a sleeve, part 2 being connected to

  part 1 by a first tier 3.

  In the interior surface of part 2 are housed

  four longitudinal grooves 5 arranged in a cross, each groove extending between the upper edge of the

  part 2 and the vicinity of its lower edge.

  In addition, in the first step 3, four lateral grooves 5 ′ have been provided, each extending from

  from the longitudinal groove 5 to the vicinity of the

  outer rim of the first tier 3, an annular groove

  re 6 being provided in the inner periphery of the par-

tie 3.

  The tip of the writing instrument is made up

  of a plurality of thermoplastic filaments which are collected

  nis in a bundle to form the felt, then the end

  of the felt thus formed is subjected to an operation

  tion of fusion, so as to form a point 9 having a flange 8 in its upper and outer peripheries

acting as a mounting device.

  At this stage, an ink guide hole 7 of small diameter having the shape of an inverted cone is also formed in the central part of the tip 9 so as to extend between the upper end of the tip and

  about its middle part. The point 9 thus formed is in-

  serée in part 2 of mouth 4 leaving it there

  fall so that the flange 8 is inserted into the groove

re annular 6 of the mouth.

  4. Next, a disc-shaped plate 10, made of hard plastic material and whose outside diameter is

  the same as the inside diameter of part 1 of the em-

  mouth is placed on the first step 3 of the mouth 4. In the central part of the plate 10 there is provided a hole 11 for ink passage which communicates with the hole 7

  ink guide tip 9. In the lower surface

  lower of the plate 10 an annular groove 12 has been formed having the ink passage hole 11 at its center and

  a transverse groove 13 which is opposite the grooves

  lateral res 5 of the mouth 4 after mounting of the

  plate 10, groove 13 which is connected to the annular groove

  re 12 at its outer ends and at hole 11 for passage

  ink age at its center. In the upper surface of the plate 10, there is provided an insertion part 14 in the form of a short sleeve which has at its center the

ink passage hole 11.

  An ink conduit 16 made of hard plastic material has a closed upper end and an open lower end so that it acts as a valve stem or piston rod. In the opposite side walls of

  the upper end of the duct 16, two orifices have been provided

  ink output fices 17. The upper surface of the former

  upper end of conduit i6 has a projection 18

  in one piece. The outer periphery of the inner end

  bottom of the conduit 16 has in one piece a seat 20 having the shape of an inverted cup which comprises a

  rim 19 extending outwards.

  The ink conduit 16 thus formed is inserted into the sleeve 1 of the mouthpiece 4, dropping it there so as to rest its seat 20 on the plate 10 so that the lower part of the conduit 16 is inserted

  in part 14 of plate 10 and that its internal hole

  laugher 21 communicates with hole 11 of plate 10. A sleeve 24 forming a handle consists of a thin tube

81932

5.

  metallic and has a male thread in the surface

  outer rim of its lower part, the extremi-

  upper and lower tees of the sleeve 24 being open.

  The sleeve 24 is connected to the mouth 4 by screwing between the male thread 23 and a female thread 24 provided on the inner surface of the sleeve 1, so that the lower end edge of the sleeve 24 urges the upper surface of the flange 19 of the conduit 16 to fix the plate 10 and the conduit 16 in place, the tip 9 is held in the bottom direction by the plate 10 and the conduit 16 is directed upwards. As a result, a clearance is formed between the outer peripheral surface of

  the tip 9 and the inner peripheral surface of the man-

  chon 2 of the mouth 4. A mouth element 29 in form

  tube of plastic material has a small diameter in a conical part and a short length in the front

  and a second step 28 in the lower peripheral surface

  lower of its middle part. In the upper surface of the second step 28 of the mouth element 29, a groove 30 for the lining has been formed which is open radially and upwards and into which is inserted a torus-shaped lining 31 having a concave part 33 which forms a cavity 32 contiguous to the wall surface of the groove

  when the trim is inserted into the groove. An in-

  seems valve box / cylinder 39 in plastic material

  door: a rim 35 extending towards the outside of the perimeter

  outer sphere near its lower edge, a seat of

  valve 36 in the inner peripheral surface of its part

  middle tie, three longitudinal ink passage holes 37 in the peripheral wall of its upper half, these

  holes being spaced from each other, and a guide hole

  38 in its upper wall, respectively. In this assembly 39 is inserted a valve body / piston assembly

  42 which has an insertion hole 40 in the central part

  trale of its lower surface and a guide rod 41 in its upper surface, respectively. The set 42

81932

6.

  is in sliding contact with the peripheral surface

  the upper half of the assembly 39, in its outer peripheral surface, while it is guided by the hole 38 of the assembly 39 in its rod 41, so as to allow movement up and down of the assembly 42 in the assembly 39. A spiral spring 43 is mounted around the guide rod 41 of the assembly 42

  on the whole 39, so that it confers an ascending force

  dante to the assembly 39, to the lining 31, to the emitting element

  closure 29 and an ink bottle 45. At this point, the

  seems valve box / cylinder 39 is inserted in the element

  mouth 29 by dropping it there so as to

  be seated on the second tier 28 of the mouthpiece element

  re 29, while the ink bottle 45 which is made of a thin metal tube having a closed upper part and a male thread 44 in the outer peripheral surface

  of its open lower end and contains, for example-

  ple, a golden or silver ink, is connected to the mouthpiece element 29 by screwing between its male thread 44 and the female thread 46 of the inner surface of the element 29, so that the lower end of the bottle thus connected urges the upper surface of the rim 35 of the valve box / cylinder assembly 39 so that the lower surface of this assembly is in firm contact with the upper surface of the lining 31 inserted in the groove 30 of the upper surface of the second step 28 of the mouthpiece element 29. In addition, the ink bottle 45 thus assembled is inserted into the sleeve 24

  forming a handle so that the ink conduit 16 is inserted

  re in the lower opening of the mouthpiece element 29

  so that the outer peripheral surface of its metered part

  diane is brought into firm contact with the peripheral surface

  inner risk of the lining 31 and that the projection 18 is inserted into the hole 40 of the valve body / piston unit 42. Next, an element 47 for reinforcing the edge,

81932

  7. ring shape is fixed in the upper opening of the sleeve 24 to prevent removal of the bottle 45

  of the sleeve 24. A cap 49 of plastic material intended

  born to cover the tip 9 has dimensions and a contour such that one can insert part 2 in the form of a sleeve

  from mouth 4 and that itself can be inserted

  removable in the upper part of the sleeve 24.

  A tail plug 50 which is removed during use is inserted into the upper end of the sleeve 24 so that its inner end abuts against

  the upper end of the bottle 45.

  More specifically, when using the ins-

  writing tool, first remove the plug 50 and the cap 49 attached to the mouth 4, then insert the cap 49

  in a concave part 51 of the upper end of the man-

  chon 24 so the bottom end of this hat

  is on the upper end of the bottle 45.

  When the user depresses the cap 49, the bottle

  ink 45, the valve box / cylinder 39 assembly, the

  niture 31 and the mouthpiece 29 are driven downwards against the upward force which is due to them

  conferred by the spiral spring 43. At the beginning of this movement-

  descending from the cap 49, the outside air is introduced into the space below the lower surface of

  the valve body / piston 42 assembly under the effect of

  ration of this set through the 9 'game,

  longitudinal grooves 5, lateral grooves 5 ', of the spoke

  annular groove 12, transverse groove 13, ink duct 16 and ink outlet orifices 17. When this downward movement of the cap 49 is continued, the space below the lower surface of the valve body / piston 42 increases again in volume to finally communicate with the interior space of the bottle 45 when the ink outlet orifices 17

  open into the interior space of the bottle

  above seat 36, so some of the ink from the

81932

  8. bottle 45 is replaced by outside air as well

  enters and flows down to enter the space

  this located below the bottom surface of the assembly

  42 through the holes 37 for ink passage.

  At the end of the insertion of the cap 49, the bottle 45, the valve box / cylinder assembly 39, the lining 31 and the mouthpiece element 29 are moved upward under the effect of the force directed into the upward direction which their

  is imparted by the spring 43. In such an upward movement

  dant, when the lower end of the hole 37 for ink passage is at the same level as the lower surface of the valve body / piston assembly 42, the ink being

  in the space below this set is trans-

  to the ink duct 16 via the ports

  these 17 ink output. More specifically, when the ope-

  sinking ration and the slackening operation of the

  skin 49 are alternately repeated, the ink that contains

  the bottle 45 is gradually replaced by the air ex-

  to be introduced into point 9 via the

  middle of the ink duct 16 and the guide hole 7 of

  creates this point, so that the point is moistened

with the ink thus introduced.

  As described above, the writing instrument has a point which receives the material in the liquid state such as ink to be saturated, material

  which is supplied by the container incorporated at the upper end

  lower tip, the instrument being characterized in that: the elongated ink guide hole is formed in the upper end of the tip; the depth of the hole reaches the middle part of the height of the point, this hole receiving the material in the liquid state supplied by the container. Therefore, the liquid material that receives

  the ink guide hole allows the tip to be sufficient

  healthily saturated in a short time, while this

  ink supply provides the tip with more

81932

9.

  liquid. In addition to the above benefits, given

  born that it is possible to supply the tip with the material in the liquid state from the ink guide hole over a very short distance, the difference in the quantity of ink that the tip needs between a quick write -

  de and slow writing is not a drawback

  deny for the instrument of the present invention.

  The present invention is not limited to the examples

  ples of realization which have just been described, it is on the contrary susceptible of modifications and variants

  which will appear to those skilled in the art.
