Definitions

  • tubular film bags are increasingly used due to their low use of material, each of which ends in the ends closed with a clip.
  • tubular bags For emptying, these tubular bags are inserted into rigid containers or cartridges which have a discharge opening near one of the two tubular bag ends.
  • the tubular bag In the device known from DE-A-38 26 887, the tubular bag is pierced with a mandrel which is manually inserted through a dispensing nozzle provided on a cartridge cap and then pulled out again.
  • Another arrangement is known from DE-U-91 03 038, in which the cap of a cartridge receiving the tubular bag near a lateral dispensing opening has a knife which cuts one of the folds in the region of the front bag tip when pressure is exerted on the rear tubular bag end.
  • tubular bag known from EP-A-0 620 165 in which the outermost layer of the bag film has a weakened area to achieve a predetermined breaking point, is intended for opening by means of a piercing mandrel provided in a dispensing device.
  • the invention has for its object to provide a tubular film bag that can be opened for emptying with the most expensive possible means.
  • the solution to this problem according to the invention is characterized in claim 1.
  • the fold provided in the tubular bag film afterwards, which locally abruptly reduces the bag cross-section, leads to the fact that the maximum tension in the film occurs at a point immediately next to the fold when pressure is applied. Therefore, if, as usual, the film tube is pressurized for emptying by a piston acting on its rear end, the film bursts specifically at the point of greatest tension, i.e. immediately within the crease.
  • the tubular bag according to the invention therefore does not require any additional measures such as knives or mandrels on the dispensing device; rather, it has a predetermined breaking point due to its design.
  • the measure according to the invention can be carried out easily and inexpensively.
  • the embodiment of the invention according to claims 3 to 5 is characterized in that no additional material is required.
  • the V-shaped weld seam according to claim 4 in turn ensures an exact positioning of the predetermined breaking point. If the weld seam is torn open, the desired dispensing opening is formed in the cutout according to claim 5.
  • the design of the invention according to claims 6 and 7 has the advantage of being particularly easy to manufacture, the clip being able to be attached in the same operation with the clip closing the adjacent tubular bag end. A precise positioning of the predetermined breaking point is achieved by the measure of claim 7.
  • the tubular bag shown in FIGS. 1 and 1a is closed at both ends with a metal clip 10 .
  • a fold 11 is made in the tubular bag film near one end and is fixed by a weld seam 12 .
  • the weld seam is V-shaped and has a tip 13 facing the inside of the bag. As a result, the cross-section of the bag at the point of the tip 13 is significantly reduced locally compared to the surroundings.
  • the film material is removed in the gusset area of the weld seam 12 .
  • the tension in the tubular bag film becomes maximum at the point of the tip 13 , so that the weld seam 12 begins to open at this point and the tubular bag contents can escape through the opening created there.
  • the tubular bag is used, for example, in connection with the activating device known from DE-U-91 03 038, it is inserted into the cartridge present there in such a way that the fold 11 comes to rest in the region of the dispensing opening provided in the side of the cartridge cap.
  • the cartridge cap can also be glued to the front end of the tubular bag and form a marketable unit with it.
  • the fold 11 formed near the upper closure clip 10 is fixed by a metal clip 15 .
  • the bracket 15 has two square legs that are biased against each other.
  • a triangular clip for example, which forms an inwardly directed tip, at which - as in FIG. 1 - the maximum stress occurs.
