Background of the Invention The present invention relates to a device for applying writing, drawing, printing, or painting fluids etc. to a surface, whereby the device comprises a fluid container, a respective writing, drawing, printing or painting applicating tip etc., an air inlet tube that connects the interior of the fluid container to the surrounding atmosphere, and a capillary fluid reservoir.
Devices of the aforementioned kind are known in many variations and are employed in many private and commercial sectors, for example, as markers or painting utensils etc.
All of these devices have one common disadvantage: the fluid container can only hold a limited supply of writing fluid. ~hen attempting to increase the capacity of the fluid contalner for the respective writing fluid in the aforementioned known devices by increasing the size of the fluid container itself, this would result ln the leakage of the writing fluid rom the container via the applicating tip because of the weight of the f~luid itself, when the device is a vertical position usually necessary for writing.
This approach is therefore not applicable.

When attempting to prevent leakage of fluid from larger liquid containers by directly filling the liquid container, completely or partially, with a capillary reservoir means it is possible to control leakage for such larger fluid containers, but this embodiment has the unacceptable disadvantage that during the writing process a great portion of the fluid will remain in the capillary reservoir means thereby being inaccessible for the writing, drawing, painting or printing process. The result would again be a device with an accessible fluid volume that is to small.
It is therefore an obJect of the present invention to provide a device of the aforementioned kind with which, in principal, no limitation of the filling amount of the fluid is known, which is easy to operate and to handle, : which may be used for various applications of fluids~ and which is also easy to manufacture. :

Summary of the Invention The device of the present invention is primarily characterized by the capillary fluid res0rvoir being arranged within a fluid convey~ng connection between the fluLd that is contained in the fluid containar and the applicating tlp, whereby the fluid convaying connection is interrupted when the applicating tip is pointed in ~20 a downward direction.
~The advantage of the device of the present :~ : invention is that, in principal, the conveying of the 1uid to the applLcating tip is independent of the volume of the fluid container and thus from ~: :
the momentary fluid volume. When the devics is : - 5 -:

used ~or writing, drawing, printing or painting, i.e~, when the applicating tip is directed downward toward the surface, the filling process of the capillary fluid reservoir is interrupted.
The fluid reservoir is only filled when the device is in a horizontal position or is essentially positioned such that the applicating tip is pointing upward, i.e., in a vertical respectively in an upwardly directed position, which may be simply achieved with a short movement of the device into one of the described positions.
The capillary fluid reservoir is dimensioned such that, depending on the embodiment of the device, writing, painting, printing, or drawing procedures may be carried out uninterruptad by supplying a sufficient amount of fluid until the respective procedure is terminated by the user of the device.
Preferably, the capillary fluid reservoir serves as the fluid conveying connection. It is advantageous that the applicating tip and the capillary fluid reservoir are embodiad as an integral part thus forming an inexpensive unit which may be produced in a simple manner.
According to a prefsrred embodiment o~ tha :
:~ ~ ~ .. ; , : ........... . . ...... - .
: : ' -' ~ ., ' .' ' ~ : ' present invention a flow reduction means is provided between the capillary fluid reservoir and the applicating tip. The flow reduction means is provided in order to adjust a predetermined fluid flow per time unit in the manner of a reducing valve which is of special importance when, after the filling process of the capillary reservoir, the fluid contained therein is at a maximum filling level.
Advantageously, the capillary fluid reservoir is enclosed by a tube, which, on the one hand, provides mechanical stability to the fluid reservoir and, on the other hand, prevents an interaction of the fluid inside the capillary flu1d reservoir with the air-filled interior of the fluid container.
To assure that during the filling process essentially the entire fluid volume inside the fluid container is introduced into the capillary fluid reservoir, the fluid conveying connectlon extends preferably into the vicinity of the bottom ; of the flu1d container, optionally via a capillary connection to the outer wall of the device.
In principle, the device is not limited to a fixed outer or inner geometry, i.e., it may be ~ 7 ~

~}~2~
embodied in any desired shape, for example, in the form of a bottle, a ballpoint pen, a fountain pen etc, Also, the cross sectional shape of the device may be chosen as desired. Advantageously, the capillary fluid reservoir has a ring-shaped or a tube-shaped cross section whereby the boundaries of the fluid reservoir are formed by a tube. This embodiment is easy to manufacture and may be providad in small spaces. The aforementioned tube may enclose the fluid res0rvoir or may be disposed inwardly from -the fluid reservoir whereby especially an embodiment is preferable in which the capillary fluid reservoir having a ring-shaped cross section is in direct contact with the fluid container and its inner wall is limited by the tube.
According to a further advantageous embodiment of the inventive device the fluid container is provided in the form of a volume-adjustable fillable container. This is achieved in the form of a conventional fountain pen with a suctlon plunger. The filling of the device may also be achieved by providing a simple filling opening into which the fluid is introduced either by conventional cartridges or by refilling from an :

For certain embodiments of the device it may be advantageous that the end of the capillary fluid reservoir that is facing the bottom of the fluid container is provided with a valve means that is in an open position when the device is in an essentially vertical position with tha applicating tip pointing in an upward direction~
This embodiment is especially advantageous when the fluid container, in a further advantageous embodiment of the device, is provided in the form of a collapsible hose. Without the provision of such a valve means for a fluid container in the form of a collapsible hose, in which naturally the volume of air within the fluid container is limited to a minimum, fluid would be constantly flowing into the capillary fluid reservoir, evsn when the device is in its writing position. This is safely prevented by the valvs means.
20 ~ It may also be advantageous that the fluid is not directly re¢aived in the fluid container which is provided in the form of a collapsible hose, but to introduce the fluid into a collapsible hose which is dlsposed in the interior of the fluid container. Thereby a device is provided which _ g :
-2 ~ ~ 2 ~
maintains its outer unchangeable shape. This is advantagesus for the safe handling of the device, whereby, due to the collapsible hose in the interior, the advantages of such a hose are still fully provided.
Finally, it is also advantageous that the air inlet tube is equipped with a space that is filled with a capillary means. The capillary means receives fluid that is introduced into the air inlet tube, for example, due to the expansion of the air volume inside the device caused by warming, by shaking or dropping the device, without a droplet leaving the air inlet opening that is connected to the surrounding atmosphere.
Description of Preferred Embodiments The present invention will now be described in detail with the aid of several specific embodiments utilizing figures 1 through 7.
The device 10 (see Fig. 1) comprises essentially a fluid container 11 which, in the embodiment representad in Fig. 1, is bottle-shaped. From the bottle neck an application or ~ writing tip 12 extends which is attached to the ; ~ bottle neck in any suitable fashion. The end of ~ the writing tip 12 that is facing the bottle :

interior is connected to a capillary fluid reservoir 15 such that a fluid conveying connection 16, as represented schematically by the arrow in Fig. 1, from the interior 25 of the fluid container 11 to the tip 12 for conveying fluid 17 contained in the capillary fluid reservoir 15 is provided. The capillary fluid reservoir 15 extends in essentially linear form from the bottom 18 to the writing tip 12.
An air inlet tube 13 connects the atmosphere 14 to the interior 25 of the fluid container 11.
The air inlet tube 13 serves to displace the fluid 17 inside the fluid container 11, which is released during the application or writing procedure, with air.
The capillary fluid reservoir 15 is enclosed - by a tube 22 which, on the one hand~ provides a mechanical stabilizing function for the capillary fluid reservoir 15 and, on the other hand, ZO prevents the interaction between the air in the interior 25 and the fluid 17 contained in the capillary fluid ~reservoir 15 as well as the : :introduction of fluid 17 into the capillary fluid reservolr 15 when the tip 12 is in a downward position. : :

The end 19 of the capillary fluid reservoir 15 that is facing the bottom 18 of the fluid container 11 is open for the introduction of fluid 17 that is contained in the fluid container 11.
Fig. 1 shows the position of the device 10 in which the tip 12, in an essentially vertical position of the device 10 respectively the fluid container 11 r is pointing in an upward direction and the capillary fluid reservoir 15 is filled with fluid 17 that is contained in the fluid container 11. In this position the capillary fluid reservoir 15 will be filled to a maximum level with liquid 17. The position represented in Fig. 1 may, for example, be achieved when the device is placed onto a surface whereby, in -this inactive position, the capillary fluid reservoir 15 will always be filled. Fig. 2 is a schematic representation of the active or writing position whereby it can be seen that in this position tha fluid 17 may not enter the capillary fluid :~ ~ reservoir 15. In this position tha device 10 may be used until tha entire fluid 17 that is contained in the oapillary fluid reservoir 15 is used up, which, when the volume of the capillary : ~ fluid reservoir 15:is suitably selected, ensures ~ 12 -:: : : ; - :, ~,. :

~ , 2 ~ Z ~d ~i 2 ~3 an uninterrupted writing procedure It is understood, that in this connection for reasons of simplifying matters only a writing procedure is addressed. The writing procedure to be carried out with the device 10 encompasses also drawing, printing or painting procedures etc., whereby for these different purposes the tip 12 must be chosen accordingly.
The relatively simple embodiment of the device 10 provides a high efficiency of the device 10 and, on the other hand, assures that the device 10 may be manufactured in a simple and inexpensive manner so that the device 10 may be supplied as a mass-produced article to a wide circle of buyers and users.
In the embodiment represented in Fig. 3 the fluid 17 is received in a collapsible hose 24 that is disposed in the interior 25 of the fluid container 11 so that thereby the entire interior 25 is filled with liquid 17. At the end 19 of the capillary fluid reservoir 15 a valve means 20 is disposed which assures that the fluid 17 may only enter the capillary fluid reservoir 15 from the fluid container 11 respectlvely the 1nter1or of the hose 24;when the filllng position according to .:
: : ~ .
Figs. 1 or 3 is assumed, but not when the writing position of the device 10 according to Fig. 2 is assumed. The valve means 20 may be actuated either by gravity or by an actuating memb~r 28 which extends from the fluid container 11 and which, against the force of a return spring that is located inside the valve means, is actuatable e~ther manually or by placing it on a surface. It is noted that it is also possible to provide the fluid container 11 itself in the form of a collapsible hose 24 (Fig. 8). In Fig. la the inner bottom of the fluid container is shown. The capillaries 29 represented therein allow the filling of the capillary fluid reservoir 15 when the fluid container 11 is in a horizontal position and when the filling level of fluid 17 is low.
The embodiment according to Fig. 4 shows a manual writing device that is commonly used ~or writing or drawing. Accordingly, the diamet~r of the fluid container 11 is adjus-ted to dimensions that are commonly used for handwriting or drawing devices. The device represented in Fig. 4 dif~ers from embodiments of the device 10 according to Figures 1 through 3 in that it is provided with a capillary fluid reservoir 15 that is not embodied - . , ~ .
with a full cross-section but is provided in the form of a ring. A tube with walls 23 is inserted into the fluid container 11. The distance between the tube respectively the tube walls 23 and the inner surface of the fluid container 11 is selected such that in the space between the tube and the fluid container 11 the capillary fluid reservoir 15 is formed. Between the capillary fluid reservoir 15 and the tip 12 a flow reduction means 21 is arranged that, in the fashion of a reducing valve, provides a predetarmined amount of fluid 17 per time unit independent of the filling lavel of the capillary fluid reservoir 15.
Thereby outer influences such as warming of the surrounding atmosphere, changes in pressure and so on are eliminated. Thus a continuous flow of fluid 17 is ensured and continuously provided.
The embodiment according to Fig. 5 differs ~ from Flg. 4 in that essentially two inventive devices are arranged in series. When the device accordlng to Fig. 5 rests in a horizontal position (Fig. 5a), writing fluid flows through a first annular space 150 (a first capillary resevoir) into the space before the flow reduction means 21 so that this space functions as a pre-resevoir.
~ ' : . ~
2 ~ .
A second capillary means 151 serves to fill the actual capillary resevoir 15 with fluid 17. In Fig. 5b the inventive device is shown in its operating position, whereby the flow of fluid 17 into the resevoir 15 is interrup-ted.
The embodiment of the inventive device 10 as represented in Fig. 6 is fundamentally identical to the embodiments of the Figures 4 and 5. The device is in the form of a common fountain pen whereby the fluid container 11 is provided in tha form of a volume-adjustable container which may ba filled by a manually actuatable filling plunger.
The tip 12 of the device 10 according to Fig. 6 is not provided in the ~orm of a tubular tip but as a pen point which is known from commonly used fountain pens.
All three embodiments shown in the Figures 4 to 6 have an alr inlet tube 13 that is provided with a spaoe 27 whlch is filled with a capillary means 26. The space 27 respectively tha capillary means 26 therein serve to intsrcept fluid 17 which may enter, due to shaking or fast movements or warming of the devlce 10, the end o the air inlet tuba 13 that exten~ds into the interior 25.

The end 19 of the capillary fluid reservoir 15 that is facing the bottom 18 of the fluid container 11 is open for the introduction of fluid 17 that is contained in the fluid container 11.
Fig. 1 shows the position of the device 10 in which the tip 12, in an essentially vertical position of the device 10 respectively the fluid container 11 r is pointing in an upward direction and the capillary fluid reservoir 15 is filled with fluid 17 that is contained in the fluid container 11. In this position the capillary fluid reservoir 15 will be filled to a maximum level with liquid 17. The position represented in Fig. 1 may, for example, be achieved when the device is placed onto a surface whereby, in -this inactive position, the capillary fluid reservoir 15 will always be filled. Fig. 2 is a schematic representation of the active or writing position whereby it can be seen that in this position tha fluid 17 may not enter the capillary fluid :~ ~ reservoir 15. In this position tha device 10 may be used until tha entire fluid 17 that is contained in the oapillary fluid reservoir 15 is used up, which, when the volume of the capillary : ~ fluid reservoir 15:is suitably selected, ensures ~ 12 -:: : : ; - :, ~,. :

~ , 2 ~ Z ~d ~i 2 ~3 an uninterrupted writing procedure It is understood, that in this connection for reasons of simplifying matters only a writing procedure is addressed. The writing procedure to be carried out with the device 10 encompasses also drawing, printing or painting procedures etc., whereby for these different purposes the tip 12 must be chosen accordingly.
The relatively simple embodiment of the device 10 provides a high efficiency of the device 10 and, on the other hand, assures that the device 10 may be manufactured in a simple and inexpensive manner so that the device 10 may be supplied as a mass-produced article to a wide circle of buyers and users.
In the embodiment represented in Fig. 3 the fluid 17 is received in a collapsible hose 24 that is disposed in the interior 25 of the fluid container 11 so that thereby the entire interior 25 is filled with liquid 17. At the end 19 of the capillary fluid reservoir 15 a valve means 20 is disposed which assures that the fluid 17 may only enter the capillary fluid reservoir 15 from the fluid container 11 respectlvely the 1nter1or of the hose 24;when the filllng position according to .:

Figs. 1 or 3 is assumed, but not when the writing position of the device 10 according to Fig. 2 is assumed. The valve means 20 may be actuated either by gravity or by an actuating memb~r 28 which extends from the fluid container 11 and which, against the force of a return spring that is located inside the valve means, is actuatable e~ther manually or by placing it on a surface. It is noted that it is also possible to provide the fluid container 11 itself in the form of a collapsible hose 24 (Fig. 8). In Fig. la the inner bottom of the fluid container is shown. The capillaries 29 represented therein allow the filling of the capillary fluid reservoir 15 when the fluid container 11 is in a horizontal position and when the filling level of fluid 17 is low.
The embodiment according to Fig. 4 shows a manual writing device that is commonly used ~or writing or drawing. Accordingly, the diamet~r of the fluid container 11 is adjus-ted to dimensions that are commonly used for handwriting or drawing devices. The device represented in Fig. 4 dif~ers from embodiments of the device 10 according to Figures 1 through 3 in that it is provided with a capillary fluid reservoir 15 that is not embodied - . , ~ .
with a full cross-section but is provided in the form of a ring. A tube with walls 23 is inserted into the fluid container 11. The distance between the tube respectively the tube walls 23 and the inner surface of the fluid container 11 is selected such that in the space between the tube and the fluid container 11 the capillary fluid reservoir 15 is formed. Between the capillary fluid reservoir 15 and the tip 12 a flow reduction means 21 is arranged that, in the fashion of a reducing valve, provides a predetarmined amount of fluid 17 per time unit independent of the filling lavel of the capillary fluid reservoir 15.
Thereby outer influences such as warming of the surrounding atmosphere, changes in pressure and so on are eliminated. Thus a continuous flow of fluid 17 is ensured and continuously provided.
The embodiment according to Fig. 5 differs ~ from Flg. 4 in that essentially two inventive devices are arranged in series. When the device accordlng to Fig. 5 rests in a horizontal position (Fig. 5a), writing fluid flows through a first annular space 150 (a first capillary resevoir) into the space before the flow reduction means 21 so that this space functions as a pre-resevoir.

A second capillary means 151 serves to fill the actual capillary resevoir 15 with fluid 17. In Fig. 5b the inventive device is shown in its operating position, whereby the flow of fluid 17 into the resevoir 15 is interrup-ted.
The embodiment of the inventive device 10 as represented in Fig. 6 is fundamentally identical to the embodiments of the Figures 4 and 5. The device is in the form of a common fountain pen whereby the fluid container 11 is provided in tha form of a volume-adjustable container which may ba filled by a manually actuatable filling plunger.
The tip 12 of the device 10 according to Fig. 6 is not provided in the ~orm of a tubular tip but as a pen point which is known from commonly used fountain pens.
All three embodiments shown in the Figures 4 to 6 have an alr inlet tube 13 that is provided with a spaoe 27 whlch is filled with a capillary means 26. The space 27 respectively tha capillary means 26 therein serve to intsrcept fluid 17 which may enter, due to shaking or fast movements or warming of the devlce 10, the end o the air inlet tuba 13 that exten~ds into the interior 25.
