Definitions

  • the invention relates to an arrangement for dispensing flowable substances from film tubes, a sealing element in the form of a collar seal the safe and ensures exact delivery of the substance from the foil bag.
  • flowable pasty materials such as sealing compounds
  • dental impression materials known from a tubular bag.
  • the Application devices required for this are described, for example, in the publication EP 0492413 described.
  • the tubular bag is introduced into a cylinder space which is from one end is loaded with a piston and at the other end where the Bag is open, has an emptying opening or dispensing nozzle.
  • the pamphlets EP 0541972, EP 0663348, WO 98/06506 and WO 98/06505 describe possibilities for squeezing flowable substances out of tubular bags.
  • Great attention is always in these publications on the sealing devices between the Tubular bag opening and the discharge opening of the dispensing device.
  • a disadvantage of the in the above Printed arrangements described for pressing flowable substances is that a reliable sealing effect of the sealing elements is not guaranteed during the entire application of the flowable substance. Especially when the application process is interrupted and at a later time Substance should be applied again at the time.
  • an arrangement for sealing is desirable, the low material costs has and avoids complex and impractical mounting options. Furthermore, the sealing arrangement should be the simple removal of the film tube guarantee from one device as well as simple and quick cleaning ensure the entire arrangement.
  • the object of the invention is therefore an arrangement for dispensing flowable substances from film tubes, which specify the above Avoids disadvantages.
  • the object is achieved by the arrangement according to main claim 1.
  • the invention Arrangement includes a sealing element in the form of a collar seal that ensures the safe and exact delivery of the substance to be dispensed.
  • the invention Sealing arrangement does not act with the discharge opening of the Output device surrounding end face together, but with the discharge opening directly. The invention is described below with reference to Figures 1, 2, 3 and 4, which illustrate advantageous exemplary embodiments, explained.
  • the arrangement consists of a film tube (1), at least one closure element (2) and at least one flange (3), the flange (3) and film tube (1) being firmly connected to one another, for example by gluing.
  • the flange (3) is designed to interact with the housing (9) of a device for emptying tubular bags.
  • a piston (10) in the tubular bag (1) builds up a hydrostatic pressure which causes the substance (8) to flow out of the opening (13) on the outlet side of the tubular bag (1) .
  • the flange (3) has the task of preventing the substance (8) from flowing into the interior of the container, device (12) (FIG. 1).
  • the sealing effect is brought about by the fact that the arrangement according to the invention in the form of a collar seal (4) interacts with an opening (11) in the housing (9), which, for example, can be conically cylindrical or rounded.
  • the sealing effect is supported by an elastic deformation of the collar seal (4) and a resulting prestress. If the substance now flows from the outlet side of the film tube (13) into the opening (11) of the housing (9), due to the pressures found in such devices, part of the substance will endeavor to flow back outside of the tubular bag or flange against the desired conveying direction . In this way, the substance will hit the inside (7) of the collar seal (4) where it will be stopped.
  • the arrangement according to the invention also ensures an exact seal when the tubular bag and the flange (3) come in once when the bag is inserted a device should tilt at an angle ⁇ .
  • the sealing effect is then due to the Collar seal (4) also enables because the collar seal (4) due to its elastic Properties in a non-rotationally metric form on the housing opening (11) can put on.
  • the arrangement according to the invention works in that it is the substance it is possible to act on the entire inside of the sealing lip (7) (Figs. 3 and 4).
  • the flange (3) has a slight circumference of the inside of the housing (9, 12) falling short (5).
  • This design of the arrangement according to the invention makes a radially offset insertion of the tubular bag into an output device impossible.
