  • Patent number: 7097075
    Abstract: The invention relates to a device for storing and dispensing a flowable composition. Said device comprises a first (1) and a second film (2), a dispensing zone (4), a first chamber (5), containing a first substance (A) and a second chamber (6), containing a second substance (B). Said chambers are interconnected by a transition zone (3) that can be selectively opened. At least one of the films is deep-drawn in the region of the chambers and at least one of the films is pre-formed in the region of the second chamber, in such a way that once the device has been activated by opening the transition zone, the first substance can to a great extent be completely transferred to a second chamber, increasing the volume of said chamber as a result.
