Definitions

  • Cartridge for holding a viscous mass
  • the invention relates to a cartridge for holding a viscous mass, in particular lubricating greases, the cartridge comprising a tube section, a follower piston which is displaceably guided therein, a cartridge base, a bottom-side dispensing nozzle for the mass, which is provided with an external thread, and a closure designed as a cover for the dispensing nozzle.
  • Cartridges with a threaded connection are known in various forms. They are used in connection with manually or machine-operated presses, in the press head of which they are held directly or indirectly in a press head
  • Connection element are screwed in.
  • the press When the press is actuated, the mass is pressed or sucked out of the pipe section, the piston shifting in the pipe section in accordance with the emptying of the cartridge.
  • a cartridge of the type mentioned is known essentially from DE 94 02 094 U1.
  • the cartridge is used to hold pasty masses, especially one-component adhesives and sealants.
  • the closure is molded directly onto the front end of the dispensing nozzle and in the manner of a - 2 - flat, conical elevation formed.
  • the cartridge is opened by cutting off the conical elevation.
  • the disadvantage here is that the cartridge can no longer be closed after opening, thus cutting off the closure, without using an additional closure element that does not directly belong to the cartridge.
  • This is disadvantageous if the cartridge does not remain in the press until it has been completely emptied, but must be replaced with other cartridges due to the fact that the most varied masses have to be pressed with the press. In this case, the cartridge screwed out of the press is open.
  • a cartridge for holding a pasty mass in which the dispensing nozzle can be closed by means of a stopper.
  • the stopper is permanently connected to the outer jacket of the tube section of the cartridge via a strip. Since in this cartridge the dispensing nozzle is not provided with a thread and there is also no provision for the cartridge to be screwed into a press, the permanent connection of the cap to the pipe section is not a hindrance. Such a cartridge construction is not suitable for use in a press.
  • a device for processing several components which has a cartridge, the dispensing nozzle of which is provided with an external thread. Locked - 3 - This cartridge opening is by means of a cover which has an internal thread. The lid is additionally provided with a central pin which can be inserted sealingly into the dispensing opening of the cartridge.
  • DE 30 28 080 AI describes a dispensing device for a liquid adhesive.
  • This has a dispenser tip which can be placed on the mouthpiece of a container which holds the adhesive.
  • the dispenser tip is closed by means of a stopper which, according to the conical design of the tip, has a conically tapering recess, which passes through a central pin which is inserted into the dispensing tip dispenser when the stopper is attached.
  • the device is originally closed in a position of the stopper opposite to its position of use. In this position, the stopper is homogeneously connected to the dispenser tip via a thin point.
  • a separate cap is placed over the stopper and the dispenser tip and placed on a container that receives the adhesive and in which the dispenser tip is held.
  • the purpose of the cover cap is to prevent the sealing plug from being inadvertently bent, in particular when the sealing plug is being transported, and thus the thin point between the latter and the dispenser tip being destroyed, with the result of the undesired separation of the sealing plug from the dispenser tip at this time.
  • Elastic container closures in which a tear tape is arranged between the lid and the container are generally known, for example from DE-AS 1 057 012 and DE-PS 27 35, 836.
  • the cartridge should be inexpensive to manufacture and also offer the possibility of easy refilling.
  • the problem of a cartridge of the type mentioned at the outset is achieved in that the cover is homogeneously connected to the dispensing nozzle opposite to its position of use, the connection of the cover and dispensing nozzle being designed as a thin point, which is arranged as a thin-walled, narrower one in the region of the front side of the dispensing nozzle Web is formed, as well as the lid has an axially extending ring shoulder, for play-free insertion into the dispensing nozzle after the lid and dispensing nozzle have been separated and after turning the lid into its position of use.
  • the lid is not connected to the dispensing nozzle, in particular molded onto it, in its position of use, thus with its closing area facing the dispensing nozzle, but in the opposite direction to its position of use.
  • the area that serves to close the dispensing nozzle after opening the cartridge is thus directed away from the dispensing nozzle.
  • This design makes it possible to manufacture the cartridge in a particularly simple manner in that the cartridge is in one piece except for the follower piston and this part is formed in particular by means of plastic injection molding.
  • the lid which is connected via the thin point to the dispensing nozzle in the area of its front side, ensures that the cartridge filled with the viscous mass is securely closed.
  • the thin point in the area of the circumferential end face of the dispensing nozzle ensures that the cover cannot be removed from the dispensing nozzle by kinking, but only by deliberately pulling or rotating it.
  • the lid is so stably connected to the dispensing nozzle that cartridges packed upright in a cardboard box allow various packaging boxes to be stacked one on top of the other. No additional cover caps are required which would have to protect the cover from the effects of force.
  • the cartridge can be opened in a simple way, - 5 - by gripping the lid and rotating or pulling, if necessary using an aid, the thin point tearing. With the cover removed, the cartridge can then be screwed into the press head or the connection element held in the press head. If the cartridge has to be exchanged for another cartridge before it is completely empty, the screwed-out cartridge is closed with the cover. In this case, the cover in its position of use is inserted without play, in particular under prestress, into the dispensing nozzle in order to achieve a sealing effect and hold. This connector is sufficient to prevent the viscous mass from escaping from the cartridge. When the lid is inserted into the outlet connection, for example the ring attachment connected to the inside of the lid contacts the interior of the ring attachment. A design is also conceivable in which the cover is not fixed without play in the ring shoulder, but instead grips from the outside over the dispensing nozzle, in particular over the thread of the dispensing nozzle, and is held there.

Abstract

L'invention concerne une cartouche prévue pour contenir une matière visqueuse, notamment des lubrifiants. Cette cartouche comporte une section tubulaire (2), un piston séquentiel guidé dans ladite section de manière à s'y déplacer, un fond de cartouche (4), une tubulure de sortie (6) prévue pour la matière et munie d'un filet (5), ainsi qu'un système de bouchage pour ladite tubulure de sortie, se présentant sous forme de couvercle (7). Selon l'invention, il est prévu que le couvercle soit solidarisé de manière homogène à la tubulure de sortie de manière opposée à sa position d'utilisation. La jonction entre le couvercle et la tubulure de sortie se présente sous forme de zone mince (13) sous forme d'entretoise étroite, à paroi mince, disposée dans la zone de la face d'about (12) de la tubulure de sortie (6). L'intérieur du couvercle (14) comporte une pièce rapportée annulaire (15) s'étendant dans le sens axial, à introduire sans jeu dans la tubulure de sortie (6), une fois que le couvercle (7) et la tubulure de sortie (6) ont été désolidarisés et que le couvercle (7) a été tourné en position d'utilisation. Lorsqu'elle est remplie, une cartouche de ce type peut être fermée de manière sûre avant utilisation, et peut ainsi être transportée en toute fiabilité. Elle peut en outre être ouverte aisément lors de sa première utilisation et la tubulure de sortie peut ensuite être recouverte aisément après utilisation. Ladite cartouche est de ce fait économique à produire et facile à recharger.
