A rupturable portion adjoins the third compartment (C) and separates the first and second compartments (A, B), from the third compartment so that in use, when the a rupturable portion is ruptured substances from the first and second compartments (A, B) can pass to the third compartment (C). A passage (16) is provided in a wall of the third compartment (C) along an edge not shared with either of the first or second compartments.
