Definitions

  • the dentist uses so-called dental materials, which are mixed shortly before use and are made up of several components. In this state, they are malleable and harden after application.
  • So-called mixing capsules are used for mixing, which can be clamped in vibration mixing devices to mix the components contained therein. If the mass is amalgam, this is taken out after the capsule has been mixed and is applied at the point of use with a dispenser. This is a tube, in the free end of which the amalgam is taken up and then applied by moving a piston at the point of use.
  • the functions of the mixing capsule and the dispenser can be combined with one another by attaching an application tube to the mixing capsule and providing a piston inside the mixing capsule, with the aid of which the mixed mass passes through the application tube is expelled (DE-C
  • the invention aims to create a mixing and application capsule that does not have the disadvantages explained above.
  • the solution according to the invention consists in the characterizing features of claim 1.
  • the invention is based on the knowledge that, contrary to the teaching of the valve capsule, it is not necessary by means of SET BLADE of a closure member to ensure that the mixture can first take place in the capsule space. Rather, by omitting the closure member, the invention allows the components to be mixed to be admitted to the application tube from the start. Although it must be assumed that the components enter the application tube largely unmixed, it was surprisingly found that a satisfactory mixing result is achieved.
  • the use of the known “floating pillow” principle (DE-C-28 31 005) is particularly advantageous, according to which at least one component is contained in the mixing space of the capsule in a film bag that opens under the mixing vibration. It has been shown that, in contrast to the dental mass, the bag remnants are not forced into the application tube by the vibration forces if they are sufficiently larger than the clear diameter of the inlet opening of the application tube. This is probably related to the fact that the comparatively large remnants of the bag find greater resistance to movement in the surrounding air and on the walls of the capsule space and therefore do not assume as high speeds as the dental mass and therefore also when it hits the opening area of the application - tubes are not subjected to such high forces that they could be forced into the narrower opening.
  • REPLACEMENT LEAF or an interruption of the mixing process for the purpose of opening a closure member can be dispensed with by hand.
  • the knowledge of the valve capsule principle is used that the mixed mass is completely in the application tube after the vibration process.
  • the application tube is separated from the capsule, as in the case of the valve capsule, and inserted into a dispenser device.
  • the application tube is expediently connected to the capsule in one piece, whereby according to a particular feature of the invention, a predetermined breaking point for separating the tube from the capsule is provided between a coupling device provided on the application tube for connecting the same to a dispenser device on the one hand and the capsule on the other hand can.
  • the predetermined breaking point is located between the coupling device and the mouth opening of the interior of the application tube in the capsule space, so that in the event that bag remnants should happen to be at the mouth opening after mixing, they still cannot get into the dispenser device with the application tube. Rather, they are safely held back in the capsule space.
  • REPLACEMENT LEAF can be drastically reduced.
  • the entire device including the application tube then consists of only two capsule parts to be welded together after the components have been filled in.
  • the actual capsule 1 is a hollow cylinder closed at both ends, which is formed from the capsule part 2 and the cover part 3 welded to it. Within its capsule space 4, it contains the components for the dental material, namely a liquid component (mercury) in the foil pouch 5 and a powdery component (silver filing) 6.
  • the capsule part 2 On one end wall, the capsule part 2 is connected in one piece to the application tube 7, the interior 8 of which has a diameter of a few millimeters (preferably 2 to 3 mm). It is connected to the capsule part 2 via a predetermined breaking point 9.
  • a thread 10 adjoins the predetermined breaking point and is provided for coupling the application tube 7 separated from the capsule 1 to a dispenser device.
  • the application tube is closed in one piece by the closure part 11, which can be separated from the latter via a predetermined breaking point 12 for opening the application tube.
  • a stopper or a cap can also be provided as a closure.
  • the interior 8 of the application tube 7 opens at 13 into the capsule space 4.
  • the predetermined breaking point 9 is located at a certain distance from it to the side of the application tube 7. If a part of the film bag 5 is in the mouth opening 13 after the mixing process, it is securely held in the capsule 1 when the application tube 7 is broken off and cannot get into the dispenser with the application tube 7.
  • the figure shows the device in the state in which it is used. In this state, it is completely hermetically sealed from the atmosphere so that no toxic vapors can escape to the outside during storage or mixing. For use, it is clamped in a conventional vibration mixer.
  • the capsule 1 is located between the clamping arms of the mixing device and is moved essentially in its longitudinal direction, preferably in a wobbling manner.
  • the bag 5 opens, leaving the liquid component that mixes with the powder 6 free.
  • the mixture takes place both in the capsule space 4 and in the interior 8 of the application tube 7.
  • the mixed mass is completely inside the interior 8 of the application tube 7. Only the empty film bag 5 remains in the capsule space 4.
  • the application tube 7 is now separated from the capsule at the predetermined breaking point 9.
  • its closure end 11 is severed via the predetermined breaking point 12.
  • the dispenser device contains a piston penetrating into the interior 8 of the application tube 7, through which the mass is expelled from the free end of the tube and applied at the point of use.

Abstract

Dispositif pour le mélange et l'application d'une masse dentaire, notamment un amalgame, présentant une capsule de mélange (1) associée à un tube d'application (7). Dans la capsule de mélange (1) sont placés les composants de la masse dentaire, dont l'un est contenu dans un sachet en feuille mince (5) qui s'ouvre sous l'effet des vibrations de mélange. Le diamètre intérieur du tube d'application (7) est inférieur aux dimensions du sachet (5). Le tube d'application (7) est raccordé en une seule pièce avec la capsule (1), mais peut en être séparé par l'intermédiaire d'une zone de rupture (9). Une fois le mélange effectué, la totalité de la masse dentaire mélangée se trouve à l'intérieur du tube d'application (7). Il ne reste dans la capsule (1) que le sachet (5) vidé de son contenu. Le tube d'application (7) séparé de la capsule peut être utilisé dans un distributeur en vue de l'application directe de la masse dentaire.
