Abstract
Described is a multiple (2-4)-compartment fluidic individually stable pre-storable composition storage and unstable mixture-forming and delivery container having separate compartments each communicating with a single mixing zone via an externally-located fluidic composition multiple delivery tube system juxtaposed with the outer surfaces of the compartment walls. These containers are well suited for storing and transporting compositions such as a cleaning agent composition, a personal care composition, an aqueous liquid detergent composition and/or a fabric softening composition and then promptly delivering the resulting unstable mixture to the desired location. The container has been advantageously found to deliver unstable mixtures which could include aqueous suspensions of microencapsulated fragrances or other ingredients.
