Description
Les stylos ou autres objets à écrire dotés d'une plume et utilisant de l'encre liquide peuvent dans certaines conditions laisser échapper cette encre, par exemple lorsque le capuchon ne protège plus l'extrémité de la plume et que celle-ci entre en contact avec une matière absorbante (une poche de vêtement par exemple). Un écoulement d'encre peut alors se prolonger dans certaines situations jusqu'à épuisement du réservoir d'encre. Le but de la présente invention concerne un dispositif destiné à éviter ces incidents.Pens or other writing objects with a nib and using ink liquid can in certain conditions let escape this ink, for example when the cap no longer protects the end of the pen and the latter comes into contact with absorbent material (a pocket of clothing per example). Ink flow may then continue in some situations until the ink tank runs out. The aim of the present invention relates to a device intended to avoid these incidents.
Suivant l'invention, le stylo ou autre objet à écrire comportant une plume présentant une fente longitudinale alimentée en encre par capillarité, est caractérisé en ce que cette fente comporte près de l'extrémité de la plume destinée à être en contact avec le papier, un orifice de section suffisante pour interrompre l'écoulement par capillarité de l'encre dans la fente, une lame étant placée en contact avec la surface de la plume de façon à pouvoir être déplacée entre une position dans laquelle, cette lame recouvre ledit orifice pour établir l'écoulement de l'encre et une position dans laquelle, la lame est dégagée de cette ouverture pour interrompre l'écoulement de l'encre.According to the invention, the pen or other writing object comprising a quill with a longitudinal slit supplied with ink by capillarity, is characterized in that this slit has near the end of the pen intended to be in contact with the paper, an orifice of sufficient section to interrupting the capillary flow of the ink into the slot, a blade being placed in contact with the pen surface so that it can be moved between a position in which this blade covers said orifice to establish the flow of ink and a position in which the blade is clear of this opening to stop the flow of ink.
Le dispositif selon l'invention consiste à utiliser les propriétés de tension de surface de l'encre pour interrompre l'écoulement dans la fente capillaire de l'extrémité de la plume en contact avec le papier. Une forme ou un orifice adapté est creusé dans la plume, dans le but de provoquer une rupture de la section du capillaire (formée par la fente de la plume) et donc d'arrêter l'écoulement de l'encre. Les dimensions de cette forme vont de 0,5 mm à 2 mm (indications non limitatives) et la distance entre la forme et le patin d'extrémité en contact avec le papier sont le plus faible possible afin d'obtenir l'arrêt de l'écriture le plus rapidement possible. Selon la géométrie de la plume, cette distance varie de 2 à 8 mm (indication non limitative). Cette forme devra être située dans une zone dégagée de tout contact non volontaire avec une pièce qui perturberait la rupture du capillaire, par exemple le support inférieur dans lequel se trouve l'amenée d'encre. Une pièce supplémentaire appelée pour la commodité : «pièce de continuité » est juxtaposée avec les deux parties de la plume pour rétablir la continuité du capillaire et donc l'écoulement de l'encre vers le patin d'écriture en contact avec le papier. La géométrie de cette pièce peut être réalisée sous la forme d'une bague, d'un patin, d'une lame ou tout autre forme nécessaire et suffisante pour assurer la continuité de l'écoulement. La surface en contact avec la forme creusée dans la plume peut présenter différents profils : sphérique, plane, incurvée, pyramidale ou autres.The device according to the invention consists in using the voltage properties of ink surface to stop flow in the capillary slot of the tip of the pen in contact with the paper. A suitable shape or orifice is dug into the pen, in order to cause a break in the section of the capillary (formed by the slit of the feather) and therefore to stop the flow of ink. The dimensions of this shape range from 0.5 mm to 2 mm (indications not limitative) and the distance between the shape and the end pad in contact with the paper are as low as possible in order to achieve the most writing stop quickly possible. Depending on the geometry of the pen, this distance varies from 2 to 8 mm (non-limiting indication). This shape should be located in an area free from any involuntary contact with a part which would disturb the rupture capillary, for example the lower support in which the supply is located ink. An additional room called for convenience: continuity ”is juxtaposed with the two parts of the pen to restore the continuity of the capillary and therefore the flow of ink towards the writing pad in contact with the paper. The geometry of this part can be produced under the shape of a ring, a skate, a blade or any other necessary shape and sufficient to ensure continuity of flow. The surface in contact with the shape dug in the pen can have different profiles: spherical, flat, curved, pyramidal or other.
Cette pièce de continuité est mise en mouvement par l'utilisateur pour interrompre l'écoulement de l'encre et / ou automatiquement lors de la fermeture du capuchon, ce qui assure une protection supplémentaire lors d'un retrait intempestif du capuchon dans un environnement absorbant ou non. La pièce de continuité peut se déplacer par rapport à la forme creusée dans la plume selon un mouvement rotatif, une translation ou un soulèvement par rapport à la plume.This continuity piece is set in motion by the user to stop ink flow and / or automatically when closing cap, which provides additional protection when removing nuisance of the cap in an absorbent environment or not. The piece of continuity can move relative to the shape dug in the pen according to a rotary movement, translation or lifting from the pen.
Cette pièce de continuité peut se situer dessous la plume si l'on ne veut pas modifier l'aspect extérieur de la plume du stylo, mais la position la plus facile à mettre en oeuvre mais non exclusive est un montage au-dessus car elle assure une protection efficace contre un contact accidentel avec la fente de la plume qui est une source potentielle de fuite importante de l'encre. L'encre résiduelle contenue dans la fente capillaire entre l'orifice de rupture et le patin d'écriture peut s'écouler, mais cette quantité étant négligeable en comparaison avec l'inconvénient précédemment cité.This piece of continuity can be located under the pen if you do not want change the external appearance of the pen nib, but the position easier to to implement but not exclusive is an assembly above because it ensures effective protection against accidental contact with the pen slot which is a potential source of significant ink leakage. Residual ink contained in the capillary slot between the rupture orifice and the writing pad can but this amount is negligible in comparison with the aforementioned drawback.
Toute utilisation de matériau modifiant les propriétés de tension de surface est envisageable pour le revêtement de la plume ou de la pièce de continuité.Any use of material modifying the surface tension properties is possible for coating the pen or the continuity piece.

permettant son déplacement entre lesdites positions.
Selon une réalisation préférée de l'invention, la lame 2 comporte des moyens

capuchon sur le stylo provoque automatiquement le déplacement de la lame 2
vers la position de recouvrement de l'orifice 5 et que le retrait du capuchon
provoque le déplacement de la lame 2 vers la position de dégagement de l'orifice

comportement de l'encre à sa surface tel que la capillarité et l'écoulement de

modifiant les propriétés de tension de surface et donc le comportement de l'encre
à sa surface, modifiant la capillarité et l'écoulement de l'encre, est appliqué à la
plume 3 et à ladite lame 2. Par ailleurs, la plume et ladite lame peuvent recevoir
