Definitions

  • the tubular bag will be there in the cap-like receiving part inserted so that its front side abuts against the support wall of the receiving part, and at its Glued circumference with the peripheral wall of the receiving part or otherwise fixed to this.
  • the bonding causes the contents of the tubular bag, when pressure is applied (usually by one of Rear acting piston) by means of a in the receiving part existing breaker is opened, only by the Outlet opening of the receiving part and from there to the intended Place of use (for example, the inlet of a Mixer), but not from the cap-like receiving part can flow behind.
  • Another function of the bond is the Hold the front tubular bag area so that he when applying the evacuation pressure in the region of the receiving part can not evade, but the film area, the above a recess containing the breaker lies, arching into it and breaking into it required voltage is set.
  • the timing of reaching this voltage is especially important if two or more Tubular bag in a common device and one accordingly multi-part receiving device simultaneously emptied become. For example, is it one of two components paste material to be produced, so it is desirable that the present in a smaller amount catalyst component just before the base ingredient starts to pour out, so that both components reach the mixer at the same time. To ensure this timing, comes It inter alia on the fact that the breaking up of each slide takes place at a certain application force. Also from this Reason is a proper gluing - or general fixation - Between the tubular bag and the breaker bearing receiving part of importance
  • U is another device for emptying a tubular bag known. There is at the front A ring with a sealing surface glued to the end of the tubular bag, when emptying with one in a cap-like Receiving part provided plant sealingly cooperates.
  • the invention is based on the object as possible safe and tight fixation of the tubular bag on the receiving part to ensure.
  • the dispensing piston can be advance unhindered until the tubular bag is complete compressed and completely emptied.
  • the fixing point the immediately surrounding the opening to be produced in the tubular bag, the amount of substance small that is within the fixation can collect under the tubular bag bottom, without the To get to the exit opening.
  • the design according to claim 2 has the advantage of accurate Orientation of the tubular bag on the transverse surface of the Receiving part.
  • the assumed preforming of the tubular bag end is also to achieve a level and to the Transverse surface parallel fixing surface on the tubular bag low.
  • the embodiment of the invention according to claim 4 avoids that still liquid parts of the adhesive in the exit area get the substance.
  • Claim 7 refers to a breaker, which in conjunction with the frontal end of the invention Fixation between tubular bag and receiving part especially good.
  • the tubular bag 10 made of a plastic film is generally cylindrical and closed at its ends in each case with a clip 11 .
  • the integrally molded plastic injection-molded part 12 has a transverse wall 13 , which forms a support surface for the end of the tubular bag 10 .
  • the transverse wall 13 In the direction of the tubular bag (in the drawing upwards), the transverse wall 13 is surrounded by a peripheral wall 14 .
  • the opposite direction goes from the transverse wall 13 from a recess 15 , which opens into an outlet nozzle 16 .
  • the recess 15 in plan view has approximately the shape of a circle segment, wherein its curved wall is parallel to the peripheral wall 14 of the receiving part 12 .
  • two mandrels 17 are integrally formed on both sides of the centrally arranged outlet spout 16.
  • the mandrels 17 are so dimensioned in their length that their tips are set back relative to the support surface formed by the transverse wall 13 .
  • the recess 15 is surrounded by an annular groove 18 which extends along the peripheral wall 14 and, as far as the given dimensions allow, is separated from the recess 15 by a web 19 .
  • the filled and closed with the clips 12 tubular bag 10 is preformed before its insertion into the receiving part 12 so that it receives a circumferential annular projection 20 at the corresponding end.
  • the lower bag tab with the lower clip 11 is pressed inward at the same time, so that - with the exception of the annular projection 20 - is formed substantially flat face.
  • the transverse wall 13 may be provided with a recess for receiving the lower bag lobes together with the clip 11 .
