Definitions
- the present invention relates to a fluid application device and its uses.
- the latter is in direct or indirect contact with a fluid delivery device.
- the ink is spread on a support, in particular by means of a rotating ball located at the end of the fluid delivery device or by means of a capillary system that may, for example have a fibrous tip, porous or extruded, a foam applicator or brush type ...
- the end of the fluid application device may also include a mechanical valve, a roller ...
- the main reservoir containing the free ink has openings towards the outside of the fluid application device, which can cause leaks in the event of temperature and / or pressure variation or case of cap pumping (ie the repetitive hooding and decapping of the article).
- These devices generally incorporate a plastic element formed of baffles (baffle) whose role is to repel the risk of leakage by artificially removing the vent of the free ink contained in the tank.
- baffle baffle
- Such a device besides its cost and its real technical difficulty of molding and repeatable treatment, does not guarantee the reliability of the system. Indeed, it only postpones the expiration of an ink leak.
- the use of a waterproof cap is essential to avoid any evaporation of the fluid it contains.
- a second type of device has a mechanical valve between the free ink reservoir and the fluid delivery device.
- the purpose of this system is to seal the free ink tank and to supply the consumer with the ink during the actuation of the valve, which is sometimes stored in a secondary fibrous reservoir before supplying the fluid delivery device.
- This mechanical valve system has many problems inherent to the large number of parts: high cost of manufacture and assembly, large dimensional variability and / or imperfect molding / machining of parts of the valve that can cause functional problems in the valve (clogging mechanical blockage or ink leakage).
- these mechanical valve systems do not have a secondary reservoir, which leads to leaks or significant flow problems in the case of a writing under stress (for example during a decapping in the pressurized atmosphere of an airplane).
- a third free ink storage device is produced by a single tank compartmentalized in a minimum of two zones, connected to each other by a continuous capillary connector up to the writing device.
- This free ink tank system remains constantly open (no valve or closure membrane), and therefore requires a porous secondary reservoir that absorbs ink leakage during temperature and pressure changes.
- This system includes a large number of plastic parts to be assembled with care, and requires a perfect dimensional control in the area of passage of the capillary connector. Despite this, this type of expensive system does not perform its function during severe temperature or pressure variations, and sagging may occur under these constraints.
- GB 578 084 and US 2 053 892 describe pens using ink cartridges closed with a rubber stopper.
- the cap When the cartridge is first used, the cap is perforated by a hollow point. The pen remains in this configuration where the cap is perforated throughout the life of the cartridge, usually until it is substantially empty.
- the cap closes and thus prevents ink remaining in the cartridge from flowing.
- the cap is pierced once during the use of a full cartridge.
- a fluid application device comprising writing, comprising a valve comprising a self-healing material that meets these requirements.
- This valve is pierced during each use of the fluid application device and closes itself at the end of each use, by stopping the writing or by the action of the user and this until the tank is empty.
- the present application relates to a fluid application device comprising a reservoir for containing a free fluid and a fluid delivery device, characterized in that:
- the reservoir is closed by a valve comprising a self-healing material
- the fluid application device comprises
- Tubular means for piercing the valve and simultaneously placing the reservoir fluid in communication with the fluid delivery device
- the present application also relates to a method of writing comprising several phases of writing and rest, characterized in that
- a user proceeds to pierce the valve, by setting relative displacement of the valve to the tubular piercing means, thereby allowing the fluid outlet of the reservoir during the writing phase - and at the end of the writing corresponding to a rest phase, the tubular piercing means are removed from the valve which closes by self-healing to close the reservoir.
- the reservoir can therefore undergo pressure variations without ink leakage.
- the writing is usually done on a writing medium, for example a sheet of paper.
- valve comprises a self-healing material ⁇ , it is one or more self-healing materials.
- distal part is referred to the part of the fluid application device furthest away from a user.
- party proximal is instead referred to the closest part of a user.
- middle part is referred to a portion located between the distal portion and the proximal portion.
- fluid application device means any device for delivering a fluid contained in a reservoir to a support, by means of a fluid delivery device.

- the piercing means are preferably set in motion by the force induced by the user during the support of the fluid delivery device on a support, the fluid delivery device providing the function of actuator.
- valve is movable and the piercing means are fixed.
- the valve is moved by an actuator accessible to the user from outside said fluid application device.
- the actuator may be connected to a rod which, during a pressure exerted by the user to write, may deform the valve causing the perforation of said valve by the piercing means, which are then fixed.
- the valve returns to its natural position, in which she is no longer pierced. The self healing is done and the valve is again unscathed.
- a push button located on the proximal end of the fluid application device
- a rod which comes into contact with the valve in order to induce its displacement until it is perforated. by the piercing means.
- the actuator may also be located on a side wall of the fluid application device: the displacement of the push button during the actuation creates for example the deformation of the valve by simple lateral compression exerted by the user.
- the piercing means withdraw from the valve (or vice versa), the valve is re-plugged, preferably instantaneously, and the system returns to its position balance by finding all its fluid tightness.
- the fluid application device may further comprise a spring-filling element such as a coil spring or a resilient flexible blade.
- the spring element causes the spacing of the piercing means relative to the fixed valve and the stopping of the piercing.
- the spring element is preferably between the actuator and the fluid delivery device.
- the external forces are not applied continuously to the actuators during writing.
- the user can exert a force on the actuator of the device causing the performance of the valve by the piercing means and the flow of fluid to the fluid delivery device. Then he can relax the force while continuing to write on a support even if the fluid application device has regained its equilibrium state, that is to say, when the valve has self-repaired. Finally, the user may again exert a force on the actuator as soon as the fluid delivery device will no longer be sufficiently supplied with fluid to write.
- This embodiment is particularly suitable when the fluid application device comprises a buffer tank since the buffer tank makes it possible to deliver the fluid over a longer period of time.
- the actuator allows removal of the piercing means of the self-healing ⁇ valve, which is in the normal closed position. Any action of an external force on the actuator then has the effect of removing the piercing means from the self-repairing valve and thus cutting the flow of fluid from the reservoir to the fluid delivery device.
- this actuator can be engaged during the recapping of the fluid application device. For example, the withdrawal of the cap from the fluid delivery device by the user drives the piercing means to pierce the valve. When the user stops using the fluid delivery device, he then returns the cap which produces the removal of the piercing means of the valve. The latter repairs and effectively closes the fluid reservoir.
- the fluid application device of the present invention is capable of delivering a fluid contained in a reservoir on demand to a fluid delivery device. In some embodiments, it also closes the reservoir containing the free fluid once the device is no longer used. This shutter can intervene very quickly and very effectively by the self-healing nature of the valve.
- the fluid delivery device is not in constant contact with the free fluid during writing and outside of writing phases.
- the use of a free ink tank sealingly closed by a self-healing valve during the rest phases effectively avoids any risk of leakage in the event of a change in temperature or pressure, even if this variation is important.
- the ink flow rate remains constant, regardless of the conditions of use when the fluid application device comprises a secondary porous reservoir.
- the transfer of ink between the free ink reservoir and the porous secondary reservoir occurs only during a short-duration perforation of the self-healing valve, the risk of leakage is also eliminated. This system does not delay leaks like conventional systems: it avoids them simply and reliably.
- the present application also relates to the use of the fluid application device described above for writing, marking, coloring, highlighting, correcting, painting, and in particular the writing method defined above, the writing term including the variants indicated above: marking coloring highlighting etc.
- the use of the fluid application device is intended for multiple uses.
- the present application also relates to a method for delivering a fluid from a reservoir on demand to a fluid delivery device comprising the following steps: (i) providing a fluid application device comprising a reservoir for holding a free fluid and a fluid delivery device, characterized in that
- the valve comprises a self-healing material
- the fluid application device comprises tubular means for piercing the valve and for placing in fluid communication between the reservoir and the fluid delivery device and means for moving the valve relative to the tubular means of the valve. Therefore, the tubular piercing means can release fluid from the reservoir to the fluid delivery device.
- this last stage includes in particular the two following modalities:
- a modality in which during the writing the user exerts a force (for example by pressing a leaf the tip of a pen) and when he stops exercising this force the closure of the valve intervenes a modality in which, for writing, a user for example removes a cap or presses a lateral actuator at the gripping area of the writing article. This action produces a reaction force on the valve that moves to a position where it is pierced by the tubular piercing means, and when the user returns the cap or releases the pressure exerted on the lateral actuator, the valve moves to a position where it closes by self repair.
- the force to produce the piercing of the valve is opposed to a force produced by an element filling the spring function now spaced from the valve the tubular means for piercing the valve. valve.
- the force for producing the piercing of the valve by the tubular piercing means is produced by the user pressing the fluid delivery device on a valve. area.

- Figures 1 and 2 show a fibrous point marker type fluid application device (1; 11) comprising a free ink reservoir (6; 16) closed off by a valve (5; an outlet port of said reservoir (8; 18).
- the valve (5; 15) is made of a self-healing material.
- the fluid application device (1; 11) comprises, as piercing means, two tubular needles (3; 13) of the hypodermic injection needle type, having in FIGS. 1 and 2 an identical length, an identical internal diameter and a identical outer diameter.
- the ends for perforating the valve (5; 15) are tapered.
- the two pairs of needles (3; 13) are connected to a fluid delivery device (2; 12) via a buffer tank (4; 14).
- the non-tapered portions (distal portions) of the needles (3; 13) are inserted into the proximal portion of the buffer reservoir (4; 14) and the proximal portion of the fluid delivery device (2; 12) is inserted into the distal portion. buffer tank (4; 14).
- each of the devices shown in FIGS. 1 and 2 comprises an actuator.
- the actuator is a push button 7a.
- the actuator is in the form of a conical cap whose tip is directed outwards. It is made of resilient plastic material.
- a pressure for example with the thumb, causes the depression of the cone (see dashed position) which comes out when the pressure of the thumb stops.
- the device 1 is provided with a spring 7c.
- the conical pushbutton 7a is connected by its center to a rod 7b which moves the valve 5 towards the tapered portions of the needles 3.
- the valve 5, like the push button 7a are each installed in force in a circular groove defined by a proximal lip and a distal lip.
- the actuator is the fluid delivery device 12.
- the device comprises a spring 17 installed between the distal portion of the valve 15 and the proximal portion of the delivery device of the fluid 12.
- the spring 17 can bear on the valve 15 as shown here or not.
- the spring 17 can then bear on the inner wall of the fluid application device (1; 11), for example on the distal lip of the holding groove of the valve 15.
- a pressure exerted on the actuator 7 has the effect of moving the center of the valve 5 to cause the perforation of said valve 5 by the needles 3.
- the ink flows by gravity or capillarity through said needles to feed the fluid delivery device 2 via the buffer tank 4.
- the actuator 7 is no longer stressed by an external force, the withdrawal of each needle 3 from the valve 5 is effected by the spring 7c.
- the valve repairs almost instantly and regains all its fluid sealing properties. The system returns to its state of equilibrium.
- the pressure caused by the support of the fluid delivery device 12 on a support has the effect of pushing the needles 13 inwardly.
