  • the inner diameter y in the area between the cap 8 and the area of the flow opening 14 is not larger than the diameter x, so that (other than Fig. 10 ) the flow closure 15 rests against the inner surface of the material capsule 10 even when displaced by the gas pressure, with the gas 4 laterally forming the flow closure on the inner surface of the material capsule 10 due to the lower contact pressure (than in the closed state of the material capsule 10 or the gas container 1). 15 flows around. In the non-actuated state of the device 20 or the gas container 1, the flow closure 15 rests on a section of the material capsule 10 (in the area of the flow opening 14), which has an even smaller diameter according to. Fig. 9 has, whereby there is such a high contact pressure that the gas 4 cannot flow around the flow closure 15 laterally.
  • the flow closure 15 is made in one piece. Fig. 9 or Fig. 10 formed from a cylindrical or disk-shaped element, preferably made of rubber.
  • the flow closure 15 can also be in two parts according to the sectional view in Fig. 11 , which shows the base body 2 in the area of the material capsule 10 of a sixth embodiment of the gas container 1 according to the invention, and can be formed from a seal 16, preferably an annular seal, and a sealing element 17.
  • a seal 16 and the sealing element 17 themselves are adapted to one another or are designed to be gas-tight with one another.
  • the sealing element 17 for the material capsule 10 is also designed in such a way that (gas) tightness is guaranteed.
  • the present invention thus discloses a system for processing a liquid with gas, the system comprising the gas container 1 according to the invention and the device 20 in which the liquid can be arranged, wherein in the working state of the device 20 the gas container 1 is held in the gas container holder 22 and a fluidic connection of the gas container 1 with the device 20 is ensured by the cap 8 of the gas container 1 being pierced by means of the piercing unit 21 in order to enable the device 20 to be used for discharging the liquid enriched with gas 4, due to the piercing of the cap 8 of the gas container 1 the closure 12, 15 of the material capsule 10 is irreversibly converted from the closed state to the open state by the gas pressure in the gas container 1 and ensures that the gas 4 flows out through the material capsule 10 in order to ensure that the gas 4 is mixed with that in the material capsule 10 arranged Soff 11 to enable.
