  • the lid 3 is with a Circlip 24 secured for transport.
  • the two foil bags 16, 16a which are connected to the first or the second lid adapter 1, 1a and which are mounted together in an interior 37 of the container 20, can be parallel on a conventional filling system for canisters via the respective lid adapter 1, 1a or be filled sequentially with a filling material, as in Fig. 12a for the first film bag 16 is shown.
  • the two lid adapters 1, 1a are closed with a respective rotary closure 6, 6a. This in Fig.
  • container 1 is particularly suitable for multi-component applications. It is also possible to replace typical canister applications by a container 25 with a container 20 of rectangular basic shape and a lid 3, which is fixedly connected to a lid adapter 1, and to fill conventional canister filling plants.
  • Fig. 13a, b show a container 25, which is similar to in Fig. 12a, b two lid adapters 1, 1a inserted in a respective cover opening 2, 2a, of which the first lid adapter 1 shown on the right has a spout opening 5 whose diameter is larger than the diameter of the spout opening 5a of the second lid adapter 1a shown on the left.
  • a filling nozzle 38 of a filling device not shown, is used, via which a gas, in the example shown in the form of compressed air, is introduced into the second film bag 16a to form a pressure pad and in this way a compressive force on the first in the interior 37 of the container 20 mounted foil bag 16 to apply.
  • the second film bag 16a which serves as a pressure bag or for forming a pressure pad, from pinching off the film bag 16 to be emptied during expansion, the second film bag 16a has a bottle neck-shaped in an area adjacent to the socket 4a of the second lid adapter 1a Constriction 41 , which widens to a farther from the neck 4a of the second cover adapter 1a, wider filling area 42 .
  • the foil bag 16a of the second lid adapter 1a expands during filling substantially starting from the bottom 21 of the container 20, so that there is no constriction of the bag 16 to be emptied.
  • This in Fig. 13a, b shown, with a locking ring 24 secured for transport container 25 can be used for example for filling goods such as ketchup, mustard, etc., which are emptied via the tap 40.
  • the material of the container 20, the lid 3, the lid adapter 1, 1a and the securing ring 24 are preferably plastic, in particular polyethylene, polypropylene, polyamides, PET or polyolefins.
  • the retaining ring 24 may also be wholly or partially formed from another, for example metallic material.
