Improvements in or relating to articles

An article for the release of a plurality of vapors, containing article: a first phase (12), liquid or solid, comprising a first vaporisable agent; a second phase (14), liquid or solid, comprising a second vaporisable agent; and a third phase (10), which constitutes a barrier between the first (12) and second (14) phases; wherein the first (12) and second (14) phases are such that if positioned in contact with each other one phase or one or more components thereof would mix with the other phase or migrate to it, in wherein the article comprises a cover (2) with a partition (8) between the first phase (12) and the second phase (14) at the beginning of use of the article, ending the partition above the bottom wall of the cover (2), being the third phase (10) in the bottom of the cover, wherein the lower edge of the partition extends in the third phase at the beginning of use of the article; wherein the onset of vaporization of the second phase is delayed thanks to the third phase and wherein when the first phase has issued from the article, in use, the third phase is exposed to air and can shrink, so the second phase can flow around the third phase and then evaporate from the article.
