<p>The present invention is directed to a cell system with at least one burstable cell (11) filled with an active composition, the cell system being characterized in that it comprises a means (15) to control the flow and direction of the cell's contents, once said at least one cell has been ruptured. More generally, the present invention is directed to an article which comprises such a cell system. Preferably, the cell system is associated with a dispersing element (12), such as for example a fibrous pad. Preferably, the force required to burst the cells is comprised within the range of 10 to 80 N. More preferably, the article is constructed so that less than 10 % product is lost per year at 35 °C/20 % RH, the barrier properties being achieved by selecting a barrier material for making either the cells, or an openable outer package hermetically closed around at least one article.</p> |
