Description

1.

  The present invention relates to a writing instrument

  re or paint and, more particularly, an instrument for

  apply a large line of ink or paint in one stroke.

  In a writing or painting instrument, in order to obtain a wide line of ink or painting in a single gesture, in various types of conventional instruments this area is increased. of writing such as the

  tip of felt, surface which is brought into contact with the surface

  face of an object that must be painted or written on.

  In such a conventional instrument, it is necessary to increase the speed of introduction of ink or paint when

  the width of the ink or paint line is larger.

  However, in the classical writing or painting instrument -

  re, there is no way to quickly introduce a

  large amount of ink or paint in the writing area

  re of the instrument. Ink or paint is introduced mainly

  partly by gravity in the writing part of the instrument

  so there is a limit to the speed of introduction or ink or paint in the writing part of

  the instrument during a writing or painting operation.

2.

  Such a limitation results in a decrease in the lar-

  ink line, paint line speed, or speed

  bending during writing or painting operations. This ty-

  pe reduction is an inherent drawback to the conventional writing or painting apparatus. The present invention relates to a writing or painting instrument for applying a large

  ink or paint line with a single gesture.

  According to the present invention, there is provided a writing or painting apparatus which comprises: a main body having a construction resembling an aerosol can, body which is filled with an application liquid such as ink or paint and aerosol propellant; and a writing portion which is mounted on the upper part of the body

  main and can conduct an opening / closing operation

re of a main body valve.

  In the writing or painting instrument of the present invention, it is possible to conduct the operation

  opening / closing the main body valve by pushing

  the writing portion of the instrument against the main body

  cipal, so that the ink received in the main body of

  the instrument is introduced into its writing portion.

  In order to conduct the opening / closing operation

  ture of the valve of the main body, the writing portion of the instrument is mounted, being movable in the axial direction,

  on the main body of the instrument to allow movement

  of the writing portion in a direction substantially parallel to the axis of the main body. Such a moving portion

  of writing is mounted on the main body via-

  re a fixing element which can be a resembling element

  blant to a ring attached to the upper part of the main body

  pal or can be a housing allowing to receive the totali-

main body.

  Preferably, the writing portion of the instrument comprises a part having a felt-like tip 3.

  made of a breathable material, part in the-

  which is preferably provided with a through hole.

  The present invention will be well understood during the

  following description made in conjunction with the attached drawing

  3 in which: The figure is a front view, partly in section, of a

  marking pen according to the present invention.

  A mode of realization will now be described in detail.

  tion of the present invention. It is clear that this

  invention is not limited to this single embodiment.

  Reference 1 in the figure represents the main body

  cipal of the marking pen, body which has a similar construction

  similar to that of an aerosol can, this construction can

  be the same as that of a conventional aerosol can. We have replaced

  fold the main body 1 of ink and a liquefied petroleum gas

  fié (hereinafter referred to as GPL), which acts as an aerosol propellant which may be the same as that used in a conventional aerosol can, for example with freon gas, nitrogen gas, etc. to the extent that the propellant does not cause any variation in the properties of the ink or paint with which it is to be

  fill the main body of the instrument.

  At the top of the main body 1 is fixed

  an element 5 resembling a fixing ring made of synthetic resin

  aesthetic. Element 5 has an open central part

  in which is inserted by sliding a cover of liiai-

  sound 3 so as to be movable in the axial direction of the body 1 in a reciprocating movement; on an upper part

  cover 3, a writing portion 4 of the pen is mounted.

  The element 5 resembling a fixing ring may have the form of a housing in which is received the entire main body 1, and in this case, the upper part of the

  housing can have the same construction as that of the

  ment 3 resembling a fixing ring for mounting

the writing portion 4.

  At the lower end of a connection part of the 4. cover 3 to the element 5, a projecting stop 7 is provided.

  which prevents the cover 3 from coming off easily-

element 5.

  In the central part of the cover 3 there is provided a tubular projection 8 which receives an ascending pipe 2a mounted in the main body 1. The front end of the pipe 2a is inserted in the tubular projection 8 when the cover 3 is mounted on the body 1 of the pen, and abuts against a part

  with shoulder of projection 8, part with shoulder which is present

  te on the inner wall of this projection. Consequently, the ascending pipe 2a moves when the cover 3 is moved back and forth in the axial direction of the body 1 to perform the opening / closing operation of

the valve.

  At the front end of the cover 3, there is provided the door

  writing 4. The writing portion 4 consists of a sheet-like element with a double layer, comprising a

  layer 4a of sheet-shaped expanded sponge and a layer

  che 4b open cell sponge in leaf shape.

  In the assembly of the portion 4, the layer 4a is fixed to the neck.

  ring 3. A fine through hole 6 is formed in the substantially central part of the writing portion 4 comprising

  double layer construction. The diameter of the through hole

  sant 6 is preferably about 2 mm. The number of holes 6 is not limited to one. In case there are several

  holes 6, each of them has a diameter of less than about 2 mm.

  However, it is not desirable to use 6 holes

  having too small a diameter, as they could become clogged

  expensive. It is not necessary to use the double layer construction in the writing portion 4 of the pen. A

  single layer construction of an open cell sponge

  tes can be used for portion 4. In this case, the

  cre is directly introduced into portion 4, while the propellant aerosol gas is released through all of portion 4 so that it is possible to ne 5.

  not leave hole 6 in this portion.

  In addition, in this case, the portion 4 can be constituted

  killed by another material such as felt, in addition to the

spongy.

  When using the marking pen of this embodiment of the invention, the entire surface

  of the felt end of the writing portion 4 stops

  be a surface of the object to be written on or painted on, and is pressed lightly against the object for

  the writing or painting operation. During such an ac-

  thrust, the cover 3 moves towards the main body

  cipal 1, so as to exert a thrust on the pipe 2a so that the valve of the body 1 opens, from which it follows that the ink

  is ejected from the pipe 2a at the same time as the air thruster

  ground. The ink thus ejected crosses the tubular projection 8 and discharges into the empty space of the cover 3 then, via the fine through hole 6, is introduced into the

  open cell cancellous layer 4b of the writing portion

  re 4 so as to allow the user to write or paint

  dre characters, etc. As the ink is dragged

  along with the aerosol propellant, its speed of intro

  duction is significantly larger than that of a conventional writing or painting instrument in which ink or paint is applied by gravity, so there is no risk of producing fine dots when writing or painting with a single gesture of a wide line of ink or paint. In addition, it is possible to freely adjust the

  writing pressure applied to portion 4 during an operation

  writing with the marking pen of this invention

  tion. Therefore, depending on the dimensions of the ink line

  or paint, it is possible to freely adjust the speed

  introduction of ink or paint during operations

  writing or painting, which makes it very advantageous

  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.
