A multichamber reservoir is made of plastic foils. The border area between both chambers may be broken for example by applying pressure on one of the chambers, so that both substances in the chambers contact each other. At least one pressure compensation chamber (11) is separated by a web (12) from at least one of the chambers (10). The pressure compensation chamber (11) is gas-permeable to the outside and the web (12) is designed in such a way that when a predefinable inner pressure is reached inside the adjacent chamber (10) the connection with the pressure compensation chamber (11) is opened. |
