  • a special feature of the known bags is to be seen in the fact that a first substance is sealed by a shell enclosed on all sides against the outside world. In the application case is by means of a Pierce attached piercing device pierce at least one envelope, so that the Substance can be emptied or empties itself due to gravity. Across from previously used glass ampoules, the bags have the advantage that when emptied no ambient air is sucked in and the substance can be emptied germ-free.
  • the object of the present invention is to provide a bag that is essential is more universally applicable and in particular adding, i.e. loosening, Suspending or mixing substances allowed immediately before use.
  • a key idea of the present invention is to be seen in the fact that one on the piercing device provided abutment designed to receive a second substance is the opposite of the interior of the bag or the first substance a release film has been cut off.

  • the second substance can in particular be in liquid, solid, powdery, gaseous or gel form Condition.
  • the first and second In principle, substance can also be the same, so that replenishment via the abutment by connecting a filling system or additional bags in the actual ones for emptying provided bag can be supplied. Will over the abutment connected second bag and lie first and second substance in the liquid state with comparable viscosity, this results in the specifically examined bag Surprisingly, a mixing ratio between the first and second substance in the Ratio 50 to 50. Via the abutment, the first substance can be tapped into Bag second substances are supplied, which only have a short shelf life in the first substance are or decay relatively quickly in the first substance. Examples of such Second substances are living microbiological cultures or sensitive substances like glutamine or enzymes.
  • An essential core idea of the invention is that between the first and second Detect substance retracted release film, which is simultaneously with piercing the Bag is perforated.

  • the recess 54 defines together with the internal thread 69 in this embodiment, a connection 57 for connecting additional bags 43, 44, 45 via connecting lines 47, 48, 49 or for connecting an emptying line 46.
  • the idea of the abutment 14 with an emptying connection 35 and / or the provision of a fluid passage 56 in the actuating piston 29 is claimed independently of the introduction of a second substance as essential to the invention.
  • the bag system shown in FIG. 7 is characterized by a high-quality bag 15, which allows a visual control option if a transparent cover 11 is provided, and from additional bags 43, 44, 45. Allow the additional bags 43, 44, 45 numerous other possible applications (mixing, staggered, completely timed spaced delivery of substance, etc.) and are also much easier constructed, both with regard to the bags 43, 44, 45 and the circuit board 30.
