Description

La présente invention concerne une cartouche d'encre pour un stylo à plume comprenant un corps de stylo apte à être vissé sur un bloc section pourvu d'une plume et d'un conduit d'encre, le corps de stylo et le bloc section délimitant, lorsqu'ils sont vissés l'un sur l'autre, un logement interne de longueur prédéterminée apte à recevoir la cartouche d'encre, laquelle est du type comportant un corps tubulaire en matière plastique rigide dont une première extrémité est pourvue d'un opercule susceptible d'être ouvert par le conduit d'encre lors du vissage du corps de stylo et du bloc section, et dont une seconde extrémité est fermée par un bouchon inamovible comportant une partie cylindrique externe et un fond transversal délimitant avec la partie cylindrique une cavité ayant une profondeur et un diamètre respectivement supérieurs à la longueur et au diamètre du conduit d'encre.The present invention relates to an ink cartridge for a fountain pen comprising a pen body capable of being screwed onto a section block provided with a feather and an ink conduit, the pen body and the delimiting section block , when they are screwed one on the other, an internal housing of predetermined length capable of receiving the ink cartridge, which is of the type comprising a tubular body of rigid plastic material, a first end of which is provided with a cover capable of being opened by the ink duct when the pen body and the section block are screwed on, and a second end of which is closed by a non-removable plug comprising an external cylindrical part and a transverse bottom delimiting with the cylindrical part a cavity having a depth and a diameter respectively greater than the length and the diameter of the ink conduit.

Les stylos plumes actuels comportent des logements internes dont la longueur peut varier légèrement d'un modèle à un autre, ce qui impose la fabrication de cartouches d'encre de différentes longueurs et entraîne des coûts de production et de gestion relativement importants.Current fountain pens have internal housings whose length may vary slightly from one model to another, which requires the manufacture of ink cartridges of different lengths and involves relatively high production and management costs.

Les cartouches d'encre actuelles sont par ailleurs pourvues d'un opercule de forme compliquée et qui, en raison des difficultés qu'il crée pour sa mise en place, nécessite la mise en oeuvre de procédés de montage complexes.Current ink cartridges are moreover provided with a cover of complicated shape and which, because of the difficulties it creates for its installation, requires the implementation of complex assembly methods.

La présente invention se propose plus particulièrement de remédier aux inconvénients ci-dessus et, pour ce faire, elle a pour objet une cartouche d'encre qui se caractérise en ce que sa longueur totale est supérieure à la longueur prédéterminée du logement interne du stylo plume, en ce que le bouchon est réalisé en matière plastique souple de telle sorte que la longueur totale de la cartouche devienne égale à la longueur prédéterminée lorsque le corps de stylo et le bloc section sont vissés l'un sur l'autre, en ce que son corps tubulaire est réalisé par moulage et comporte à sa première extrémité une collerette cylindrique dont le diamètre est inférieur à son propre diamètre, mais supérieur au diamètre du conduit d'encre, en ce que l'opercule est constitué par une bille obturant la collerette cylindrique et située à une distance de l'extrémité libre de cette dernière qui est inférieure à la longueur du conduit d'encre, et en ce que la profondeur de la cavité du bouchon inamovible reste supérieure à la longueur du conduit d'encre après le vissage du corps de stylo et du bloc section l'un sur l'autre.The present invention more particularly proposes to remedy the above drawbacks and, to do this, it relates to an ink cartridge which is characterized in that its total length is greater than the predetermined length of the internal housing of the fountain pen , in that the stopper is made of flexible plastic material so that the total length of the cartridge becomes equal to the predetermined length when the pen body and the section block are screwed one on the other, in that its tubular body is produced by molding and comprises at its first end a cylindrical flange whose diameter is less than its own diameter, but greater than the diameter of the ink duct, in that the cover is constituted by a ball sealing the cylindrical collar and located at a distance from the free end of the latter which is less than the length of the ink duct, and in that the depth of the cavity of the non-removable plug remains greater than the length of the ink duct after the pen body and the section block are screwed onto one another.

Cette cartouche peut être utilisée dans la très grande majorité des stylos plumes actuels. Etant donné que son bouchon est souple, il peut en effet se déformer aisément pendant le vissage du corps de stylo et du bloc section et absorber la différence de longueur entre la cartouche et le logement interne du stylo plume pour que ce vissage puisse toujours être réalisé à fond.This cartridge can be used in the vast majority of current fountain pens. Since its cap is flexible, it can indeed easily deform during the screwing of the pen body and the section block and absorb the difference in length between the cartridge and the internal housing of the fountain pen so that this screwing can always be carried out. thoroughly.

La présente invention permet donc de ne fabriquer qu'un type de cartouche pour plusieurs modèles de stylos plumes, ce qui réduit les coûts de production et de gestion de façon appréciable.The present invention therefore makes it possible to manufacture only one type of cartridge for several models of fountain pens, which reduces production and management costs appreciably.

Il convient par ailleurs de préciser que l'opercule de la cartouche selon l'invention est particulièrement facile à réaliser et à mettre en place et contribue également à réduire les coûts de production.It should also be pointed out that the cover of the cartridge according to the invention is particularly easy to produce and to set up and also contributes to reducing production costs.

Un mode d'exécution de la présente invention sera décrit ci-après à titre d'exemple nullement limitatif en référence au dessin annexé dans lequel :

  • la figure 1 est une vue en coupe d'une cartouche d'encre conforme à l'invention ;
  • la figure 2 est une vue en coupe d'un stylo plume dans lequel une cartouche telle que celle visible sur la figure 1 est en position de réserve ; et
  • la figure 3 est une vue en coupe analogue à la figure 2 mais dans laquelle la cartouche est représentée en position de fonctionnement.
An embodiment of the present invention will be described below by way of nonlimiting example with reference to the attached drawing in which:
  • Figure 1 is a sectional view of an ink cartridge according to the invention;
  • Figure 2 is a sectional view of a fountain pen in which a cartridge such as that visible in Figure 1 is in the reserve position; and
  • Figure 3 is a sectional view similar to Figure 2 but in which the cartridge is shown in the operating position.

La cartouche d'encre que l'on peut voir sur le dessin comprend un corps tubulaire 1 réalisé en matière plastique rigide et dont les deux extrémités sont fermées par un opercule 2 et un bouchon 3 destinés à retenir une dose d'encre 4.The ink cartridge that can be seen in the drawing comprises a tubular body 1 made of rigid plastic material and the two ends of which are closed by a cover 2 and a stopper 3 intended to retain a dose of ink 4.

L'opercule 2 est constitué par une bille de verre maintenue en position par serrage à la base d'une collerette cylindrique 5 dont le diamètre est inférieur à celui du corps tubulaire 1 et qui se raccorde à celui-ci par une partie tronconique 6. La distance séparant la bille de l'extrémité libre de la collerette 5 est désignée par l₁.The cover 2 consists of a glass ball held in position by clamping at the base of a cylindrical collar 5 whose diameter is less than that of the tubular body 1 and which is connected to the latter by a frustoconical part 6. The distance between the ball and the free end of the flange 5 is designated by l₁.

Quant au bouchon 3, il comprend une partie cylindrique interne 7 insérée dans le corps tubulaire 1, une partie cylindrique externe 8 et un fond transversal 9 délimitant avec cette dernière une cavité ayant une profondeur désignée par l₂. Il est réalisé en matière plastique souple et est fixé sur le corps 1 de manière définitive par soudage, par exemple par ultrasons.As for the plug 3, it comprises an internal cylindrical part 7 inserted in the tubular body 1, an external cylindrical part 8 and a transverse bottom 9 delimiting with the latter a cavity having a depth designated by l₂. It is made of flexible plastic and is fixed to the body 1 definitively by welding, for example by ultrasound.

La cartouche qui vient d'être décrite, et dont la longueur totale est désignée par l₃, est destinée à être insérée dans un stylo plume tel que celui représenté sur les figures 2 et 3.The cartridge which has just been described, and the total length of which is designated by l₃, is intended to be inserted in a fountain pen such as that shown in FIGS. 2 and 3.

Comme on peut le voir sur ces figures, le stylo plume comprend d'une manière connue en soi un corps de stylo 10 comportant une surface d'appui interne 11 située à une certaine distance de son fond, ainsi qu'un bloc section 12 vissé sur le corps de stylo 10, ce bloc section comportant une plume 13, un conduit d'encre 14 et une surface d'appui interne 15 entourant le conduit d'encre 14.As can be seen in these figures, the fountain pen comprises in a manner known per se a pen body 10 having an internal bearing surface 11 located at a certain distance from its bottom, as well as a screwed section block 12 on the pen body 10, this section block comprising a nib 13, an ink duct 14 and an internal bearing surface 15 surrounding the ink duct 14.

On précisera ici que la longueur 15 du conduit d'encre 14 est supérieure à la distance l₁ séparant la bille 2 de l'extrémité libre de la collerette 5 de la cartouche, mais inférieure à la profondeur l₂ de la cavité du bouchon 3 de ladite cartouche.It will be specified here that the length 15 of the ink conduit 14 is greater than the distance l₁ separating the ball 2 from the free end of the collar 5 of the cartridge, but less than the depth l₂ of the cavity of the plug 3 of said cartridge. cartridge.

On précisera également que le corps de stylo 10 et le bloc section 12 délimitent entre eux, lorsqu'ils sont vissés à fond (comme représenté sur les figures 2 et 3) un logement interne 16 dont la longueur 14 est légèrement inférieure à la longueur l₃ de la cartouche.It will also be noted that the pen body 10 and the section block 12 delimit between them, when they are fully screwed (as shown in FIGS. 2 and 3) an internal housing 16 whose length 14 is slightly less than the length l₃ cartridge.

Sur la figure 2, la cartouche est représentée en position de réserve. Dans ce cas, l'extrémité libre de la collerette 5 est appliquée contre la surface d'appui 11 du corps de stylo 10 tandis que l'extrémité libre de la partie externe 8 du bouchon 3 est appliquée contre la surface d'appui 15 du bloc section 12, le conduit d'encre 14 s'avançant dans la cavité du bouchon 3 sans atteindre le fond 9.In Figure 2, the cartridge is shown in the reserve position. In this case, the free end of the flange 5 is applied against the support surface 11 of the pen body 10 while the free end of the external part 8 of the cap 3 is applied against the support surface 15 of the block section 12, the ink duct 14 advancing in the cavity of the plug 3 without reaching the bottom 9.

Lorsque l'on a vissé à fond le corps de stylo 10 et le bloc section 12 l'un sur l'autre, le bouchon 3 s'est déformé sans résistance en raison de sa souplesse, ce qui a permis de réduire la longueur de la cartouche de la valeur 13 à la valeur 14 sans que le conduit d'encre 14 atteigne le fond 9.When the pen body 10 and the block have been fully screwed section 12 one on the other, the plug 3 deformed without resistance due to its flexibility, which made it possible to reduce the length of the cartridge from the value 13 to the value 14 without the conduit ink 14 reaches bottom 9.

Sur la figure 3, la cartouche est représentée en position d'utilisation. Dans ce cas, l'extrémité libre de la partie externe 8 du bouchon 3 est appliquée contre la surface d'appui 11 du corps de stylo 10 tandis que l'extrémité libre de la collerette 5 est appliquée contre la surface d'appui 15 du bloc section 12, le conduit d'encre 14 ayant poussé la bille 2 à l'intérieur de la cartouche et permettant à l'encre 4 de parvenir jusqu'à la plume 13.In Figure 3, the cartridge is shown in the use position. In this case, the free end of the external part 8 of the plug 3 is applied against the bearing surface 11 of the pen body 10 while the free end of the flange 5 is applied against the bearing surface 15 of the block section 12, the ink duct 14 having pushed the ball 2 inside the cartridge and allowing the ink 4 to reach the pen 13.

Lorsque l'on a vissé à fond le corps de stylo 10 et le bloc section 12 l'un sur l'autre, le bouchon 3 s'est à nouveau déformé sans résistance pour réduire encore la longueur de la cartouche de la valeur 13 à la valeur 14.When the pen body 10 and the section block 12 were screwed in all the way, the plug 3 again deformed without resistance to further reduce the length of the cartridge from the value 13 to the value 14.

La présente invention permet d'utiliser une même cartouche dans des stylos plumes de différents modèles. Il suffit en effet que la longueur 13 de la cartouche conforme à l'invention soit légèrement supérieure à la longueur 14 du logement interne 16 de ces stylos plumes.The present invention makes it possible to use the same cartridge in fountain pens of different models. It suffices that the length 13 of the cartridge according to the invention is slightly greater than the length 14 of the internal housing 16 of these fountain pens.

Pour être complet, on précisera enfin que la bille 2 constitue un opercule bon marché et facile à mettre en place, et qu'elle peut être poussée sans effort dans la cartouche par le conduit d'encre 14 lors du vissage du corps de stylo 10 et du bloc section 12.To be complete, it will finally be specified that the ball 2 constitutes a cheap and easy-to-install cover, and that it can be pushed effortlessly into the cartridge by the ink conduit 14 when the pen body 10 is screwed and block section 12.
