Abstract
A cell system has one or multiple burstable enclosures or closed cells which contain an active composition, such as a fluid or solid (including powdered) product, preferably a liquid product, which is released therefrom when the enclosures or closed cells are ruptured. Each enclosure or cell is provided with a flow control which controls the direction and flow of the composition outwardly of the enclosure or cell when the enclosure or cell is ruptured. The flow control is formed by a film covering one side of an enclosure or cell with the film having a cut-out portion forming a flow control window. The composition can be a face cleaning lotion or cream, a disinfectant, a household cleaning composition, a perfume, a polish or a medicament.
