  writing or painting device comprising a valve for controlling

  der (adjust) the quantity of ink introduced or other liquid.

  The writing instrument described below is understood to denote a felt instrument, while the painting instrument relates to an instrument for applying a liquid.

for nail care.

  Various kinds of writing or painting instruments have been proposed heretofore (hereinafter to simplify

  by writing instruments), which includes a valve for

  order / adjust the amount of ink etc. introduced.

  However,. in such a classic writing instrument

  ture, as the ink tank and the valve are separated to form separate assemblies, the number of components of a conventional writing instrument is sufficiently high

  to complicate assembly and increase assembly time

  ge, so the manufacturing costs are high.

  These are the problems that a conventional instrument can raise.

than writing.

  Furthermore, since the reservoir and the valve constitute separate assemblies, it is not proposed to

  a construction in which the tank is of the car type

  button to make it removable interchangeable.

  An object of the present invention is to solve the problems set out above by providing an instrument

  writing or painting device comprising a valve for controlling

  der / adjust the amount of ink or liquid paint intro-

  pick, valve which is integrated into a cartridge type tank

  che filled with ink or liquid paint and has a res-

  valve fate, including the support. is integrated into the tank at

inside of it.

  It is preferable that the valve components

  are assembled with the tank in one piece.

  Another object of the present invention is to pre-

  see a cartridge for ink or liquid paint, the cartridge

  che constituting a reservoir which receives ink or paint

  liquid and is integrated with a valve spring holder

  to be assembled with a valve spring, a valve rod

  ve and a valve seat integrated in the interior

of the tank.

  The cartridge has a sealing means in

  its junction part, this means possibly being an O-ring.

  Another object of the present invention is to provide a writing or painting instrument in which a support

  valve spring for controlling / adjusting the volume

  ink or liquid or paint product contained in a

  tank is integrated with the tank which constitutes a

  button for ink or liquid paint so as to form a single unit with the valve spring, the valve stem and the valve seat inside the cartridge, valve which

  has an insertion hole in which a portion of the rod

  tion of the main body of the writing instrument is inserted

  axially, while the valve stem is assembled from

  so as to removably abut against the rod part

  tion of the main body. The cartridge-shaped reservoir 3. comprises a means making it possible to seal the junction part. The joining part is fixed to a part

  inside the main body of the writing instrument

  ture which further comprises a holding means so as to maintain a junction relationship established between the cartridge-shaped reservoir and the main body of the writing instrument. It is preferable that the sealing means is

consisting of an O-ring.

  The holding means may consist of an element

  hat-shaped which is screwed onto the main body

of the writing instrument.

  The writing instrument and its cartridge can

  be constructed with conventional components.

  The present invention will be well understood during

  the following description made in conjunction with the drawings

  attached in which: Figure 1 is a longitudinal sectional view

  a writing felt fitted with a tank in the shape of a car-

  button according to the present invention; Figure 2 is a longitudinal sectional view

  a marking felt comprising a spring support se-

  the present invention; and FIG. 3 is a view in longitudinal section of another marking felt having a construction different from

  that of the felt represented in figure 1.

  In FIG. 1, the reference A represents a writing felt and the reference 1 a tubular outer handle of the felt, at the front end of which is screwed a front handle

  tubular 2. An ink inlet tube and the like and a plug

  chon 4 abutting against the outer front surface of the tube 3 are secured between the front end of the outer handle 1 and

  a stepped part provided inside the front handle 2.

  In the front side of the plug 4, the core 5 of the felt is fixed to the front handle 2 so as to be held there while being 4. covered by a support 6 and communicating with the tube 3

  through an opening 4a formed in the par-

central tie of the plug 4.

  An inner cylinder 8 resembling a cartridge is removably mounted and can move inside the outer handle 1 so that it can be animated by a

back and forth movement.

  The inner cylinder 8 comprises a storage tank

  cre 9, a one-piece valve with its front end and a rear plug 10 hermetically closing its rear end. The valve comprises a spring support 11 in one piece with the inside of the cylinder 8, a rod 12, a seat 13, a gasket 14, a fixed tube 15, and a spring 16 mounted between

the support 11 and the rod 12.

  The support 11 comprises a base portion 17 in sail-

  binds inward on the inner wall of the inner cylinder

  8 so as to substantially take the form of a bar-

  gue, and a tubular member 18 extending towards the rear of the base portion 17. In the rear end portion of

  the tubular element 18 is a stepped part 19 allows

  both to receive the spring 16. The tubular element 18 is arranged along the axis of the inner cylinder 8. In the element

  tubular 18 is inserted the valve stem 12 in the form of a colon

  ne circular which comprises a stepped portion 20 for receiving the spring 16, provided in a position close to the front end of the rod 12; and a valve part 21 having a conical front end. The valve part 21 of the rod 12

  is always stressed towards the front end of the handle ex-

  1 by the spring 16 so as to be brought into contact

  hermetic contact with the annular seat 13 which abuts against the base part 17 of the support 11. In the extreme front side of the seat 13, a ring-shaped lining 14 is

  secured between the seat 13 and the fixed tube 15 which is vis-

  s in the front end of the cylinder 8. As the ink received in the tank forming part 9 of the cylinder 8 having the 5. previous construction is prevented from flowing thanks to the rear plug 10 and the valve, the cylinder 8 can be removably attached to the outer handle 1 in the manner

a cartridge.

  When the cylinder 8 is inserted into the outer handle 1 from its rear end, the tube 3 fixed

  inside the handle 1 passes through the fixed tube 15, the lining

  re 14 and seat 13, so the rear end of the

  tube 3 abuts against the rod 12 and is held in this posi-

  tion, while the lining 14 hermetically secures the tube 3 over its full circumferential length. So as to prevent the cylinder 8, mounted in the outer handle 1,

  accidentally fall out of this handle, a cap 22 is screwed

  dried on the rear end of the outer handle 1. In this case, when pushing an end cap, which is transferred from the front end of the instrument to its rear end, with a force greater than the elastic force exercised by the

  spring 16 so as to push the cylinder 8 outwards

  mity before the instrument, the hermetic contact established between the valve stem 12 and the valve seat 13 disappears because the stem 12 abuts against the tube 3 in order to prevent it from moving forward, while the seat 13 moves forward along with cylinder 8. As a result

  that the ink flows between the rod 12 and the seat 13 to

  trer only in the tube 3, then is introduced into the core 5 of the felt, because the lining 14 in the form of a ring prevents it from flowing forward through its

  inner periphery. When the thrust applied to the

  back of the writing instrument is removed, the cylinder

  dre 8 is moved backwards by the elastic force of the spring 16 acting on the support 11 of the cylinder, so that the seat 13 comes into contact with the part 21 of the rod

  valve 12 to prevent the passage of ink. When the cylin-

  dre 8 is removed from the rear end of the outer handle 1, the contact established between the seat 13 and the rod 12 is maintained 6. by the elastic force of the spring 16 so that there is no problem of leakage from the ink, while the ink having flowed into a space between the rod 12 and the lining 14 is practically removed from the tube 3 by the lining 14, so as to be recovered and prevented from entering

  in tube 3; there is therefore no risk of staining by the

  cre. As described above, the cylinder 8 serves

  ink tank built into the valve so that it is pos-

  likely that this cylinder has a relatively simple construction,

  while having the shape of a cartridge.

  In FIG. 2, the reference B represents a marking felt and the reference 23 a handle comprising a part to

  reservoir 24 in its hollow central part. The rear end

  The handle 23 is hermetically closed by a rear plug 10 'after insertion. In the front end of the handle 23

  forming the main body, a valve is provided which is sensitive

  similarly to that of the felt in Figure 1. In this valve, a spring support 11 ', a spring 16' and a valve stem 12 have a construction similar to that of the felt valve in Figure 1, while 'In place of the ring-shaped packing 14 which is shown in Figure 1, a spongy ring-shaped element 25 is used which is provided on the front side of the seat 14' of the valve. In addition, in the front side of the sponge element 25, a front handle 2 ′ is provided which is screwed into the handle 23 of the main body. The handle

  front 2 ′ and the spongy element 25 have a fine central hole

  tral through which the core 26 passes in the form of a circular column of felt. The core 26 is connected to the front end of the valve stem 12 '. As the valve stem 12 'is biased towards

  the front by the elastic force of the spring 16 ', the valve rod

  ve 12 'is generally in hermetic contact with the seat 14' in order to prevent the ink received in the reservoir part 24 from leaking. When the core 26 is pushed backwards with a force greater than the elastic force of the spring 16 ', the valve stem 12' is driven backwards in the support of the 7. spring 11 'so that the contact established between the rod 12 'and the seat 14' disappears to form a play between them, play through which the ink flows and is absorbed

  temporarily by the spongy element 25, via

  re from which the ink is introduced into the core 26. In this case,

  the sponge element 25 prevents the ink from flowing, and the

  cre is gradually introduced into the core 26, the element 25

  serving as a means of regulating the quantity of ink introduced

te in the soul 26.

  In Figure 3, reference C represents another

  marking felt having a construction different from that

  the felt of Figure 1, felt C which also has a different construction from that of the felt of Figure 2 in that the handle 23 'of the main body has the shape of a one-piece ink tank 24' with no rear opening, the 11 "spring support is constructed of

  extension of the side part with extreme front opening

  handle 23 'so as to form an internal hole

  for the latter, and the valve seat 14 ", the spon-

  25 'and the 2 "front handle are arranged outside

  23 'handle. However, there is no essential difference

  tielle of operation and effect between these marking instruments so that the valve also has a construction and an action substantially identical to those of the valve

  the instrument shown in Figure 2.

  As described above, according to the present in-

  Note, the spring support used in the valve is in one piece with the ink tank inside of it so that the valve does not have to be made up of elements separate from those of the ink tank to make possible simplification of construction, assembly and other steps of manufacturing the writing instrument

of the present invention.

  As it is possible to integrate the valve with the ink tank inside of it, it is possible 8. to give the ink tank the shape of a cartridge so that the tank can be fixed removably

  to the main body of the writing instrument.

  The present invention is not limited to the examples

  magpies which have just been described, it is on the contrary subject to modifications and variants which

will appear to those skilled in the art.
