Description

- 1 - Domaine technique La présente invention concerne le domaine des cartouches amovibles contenant de la graisse et plus particulièrement les cartouches de graisse utilisable dans des pompes ou pistolets à graisse. La cartouche selon l'invention comprend un tube remarquable en ce qu'au moins une des extrémités dudit tube est obturée par un film thermocollé sur ledit tube.TECHNICAL FIELD The present invention relates to the field of removable cartridges containing grease and more particularly to grease cartridges that can be used in pumps or grease guns. The cartridge according to the invention comprises a remarkable tube in that at least one of the ends of said tube is closed by a heat-sealed film on said tube.

Technique antérieure La lubrification des pièces mécaniques est couramment mise en oeuvre grâce à des pompes à graisse également appelées pistolets à graisse. Ces pompes comprennent un réservoir à graisse cylindrique destiné à recevoir de la graisse en vrac ou des cartouches amovibles contenant de la graisse. L'utilisation des cartouches de graisse permet d'éviter à l'utilisateur de manipuler la graisse lors du remplissage du réservoir de la pompe. Le remplissage du réservoir peut s'effectuer rapidement et proprement sans contaminer l'extérieur de la pompe et les mains de l'utilisateur. Les cartouches amovibles utilisables dans les pompes à graisse se présentent sous la forme d'un tube cylindrique, en plastique ou en aluminium, bouché à une de ses deux extrémités par une membrane circulaire rigide moulée concomitamment avec le dit tube et à l'autre extrémité par un bouchon amovible coiffant ou rentrant. Ces pièces sont complexes à produire car elles doivent comprendre en outre les moyens permettant leur retrait avant la mise en place de la cartouche à l'intérieur du réservoir de la pompe. -2 Ces moyens se présentent habituellement sous la forme d'un anneau à ouverture facile, associé à ladite membrane, permettant à l'utilisateur d'exercer une traction sur la pièce cylindrique pour provoquer l'ouverture de la cartouche. Afin de faciliter ladite ouverture, la pièce cylindrique est avantageusement pourvue d'un amincissement à sa circonférence. La pose de cet anneau et la présence de l'amincissement entraine une augmentation du coût de la 10 production des cartouches de graisses ainsi que l'utilisation d'une quantité de matière importante. Exposé de l'invention La présente invention propose une cartouche destinée 15 à recevoir de la graisse comportant un nouveau mode d'obturation plus facile à mettre en place et plus économique que ceux utilisés dans les modèles de l'art antérieur. Plus particulièrement, la présente invention concerne 20 une cartouche destinée à contenir de la graisse comprenant un tube remarquable en ce qu'au moins une des extrémités dudit tube est obturée par un film thermocollé sur ledit tube. Selon un mode de réalisation préféré le thermocollage 25 du film est obtenu par l'application sous pression d'une enclume chauffée sur le film placé à une extrémité dudit tube. Selon un mode de réalisation préféré de l'invention, ledit film est en plastique ou en aluminium et encore plus 30 préférentiellement en polyester. Selon un autre mode de réalisation préféré ledit film est un film multicouche comprenant une couche de polyester et une couche de rayopeel.® -3 - Selon un mode de réalisation préféré ledit film à une épaisseur comprise entre 100 et 200 pm et de façon encore plus préféré entre 100 et 150 pm. Selon un autre mode de réalisation, ledit film est en 5 aluminium. Ledit film a préférentiellement une épaisseur comprise entre 0.10 et 0.15 mm. Selon un mode de réalisation préféré, ledit tube est en matière plastique et de façon tout à fait préféré en 10 polyéthylène haute densité ou en polypropylène Selon un mode de réalisation préféré, ledit tube comprend un bord libre plat, destiné à venir en appui contre ledit film, s'étendant perpendiculairement à l'axe longitudinal dudit tube.Prior Art Lubrication of mechanical parts is commonly carried out by means of grease pumps also called grease guns. These pumps include a cylindrical grease tank for receiving bulk grease or removable cartridges containing grease. The use of grease cartridges prevents the user from handling grease when filling the pump tank. The filling of the tank can be carried out quickly and cleanly without contaminating the outside of the pump and the hands of the user. The removable cartridges used in the grease pumps are in the form of a cylindrical tube, plastic or aluminum, plugged at one of its two ends by a rigid circular membrane molded concomitantly with said tube and at the other end by a removable cap styling or re-entering. These parts are complex to produce because they must further include the means for their removal before the introduction of the cartridge inside the pump tank. These means are usually in the form of an easy opening ring, associated with said membrane, allowing the user to exert traction on the cylindrical piece to cause the opening of the cartridge. In order to facilitate said opening, the cylindrical piece is advantageously provided with a thinning around its circumference. The installation of this ring and the presence of thinning results in an increase in the cost of producing the fat cartridges as well as the use of a large quantity of material. DESCRIPTION OF THE INVENTION The present invention proposes a cartridge intended to receive grease comprising a new closure mode that is easier to put in place and more economical than those used in the models of the prior art. More particularly, the present invention relates to a cartridge for containing grease comprising a tube which is remarkable in that at least one of the ends of said tube is closed by a heat-sealed film on said tube. According to a preferred embodiment, the heat-sealing of the film is obtained by applying under pressure a heated anvil to the film placed at one end of said tube. According to a preferred embodiment of the invention, said film is made of plastic or aluminum and even more preferably of polyester. According to another preferred embodiment, said film is a multilayer film comprising a polyester layer and a layer of rayope. According to one preferred embodiment, said film has a thickness of between 100 and 200 μm and even more so. preferred between 100 and 150 pm. According to another embodiment, said film is made of aluminum. Said film preferably has a thickness of between 0.10 and 0.15 mm. According to a preferred embodiment, said tube is made of plastic and quite preferably made of high-density polyethylene or polypropylene. According to a preferred embodiment, said tube comprises a flat free edge intended to bear against said film, extending perpendicularly to the longitudinal axis of said tube.

15 Selon un mode de réalisation encore plus préféré, ledit bord libre plat se prolonge perpendiculairement à l'axe longitudinal dudit tube et vers l'extérieur dudit tube. La présente invention concerne également une 20 cartouche selon l'invention remarquable en ce que ledit tube contient de la graisse. Description sommaire des figures La figure 1 présente une vue de coupe d'un mode de 25 réalisation d'une cartouche de graisse selon l'invention. Description des modes de réalisation La cartouche 1 présentée à la figure 1 est constituée par un tube 2 creux en plastique, et préférentiellement en 30 PP ou PEHD, dont l'une des extrémités 3 est obturée par un film 4 en PE thermocollé et à l'autre extrémité par un bouchon coiffant ou rentrant. Le film en polyéthylène 4 comprend préférentiellement une languette 5 s'étendant vers l'extérieur du tube 2 et -4 qui permet à l'utilisateur d'exercer une traction sur le film 4 est ainsi pouvoir ouvrir la cartouche. Le film 4 repose sur les bords libres 6 du tube 2.5According to an even more preferred embodiment, said flat free edge extends perpendicularly to the longitudinal axis of said tube and towards the outside of said tube. The present invention also relates to a cartridge according to the invention which is remarkable in that said tube contains grease. Brief Description of the Figures Figure 1 shows a sectional view of an embodiment of a grease cartridge according to the invention. DESCRIPTION OF THE EMBODIMENTS The cartridge 1 shown in FIG. 1 consists of a hollow tube 2 made of plastic, and preferably made of PP or HDPE, one of its ends 3 being closed by a film 4 made of thermally bonded PE and other end by a styling or retracting cap. The polyethylene film 4 preferably comprises a tongue 5 extending towards the outside of the tube 2 and -4 which allows the user to exert a pull on the film 4 is thus able to open the cartridge. The film 4 rests on the free edges 6 of the tube 2.5
