A delivery system comprising a first container (24) in which a first material is to be held; a second container (66) in which a second material is to be held, the second container being capable of being put into fluid communication with the first container to enable the second material to be added to the first material to form a flowable composition in the first container, and user-actuable means (72) for mechanically generating a pressure differential to allow all of the flowable composition which is discharged to be discharged from the first container (24) at any orientation.

1. A delivery system comprising:(a) a first container in which a first material is to be held; (b) a second container in which a second material is to be held, the second container being capable of being put into fluid communication with the first container to enable the second material to be added to the first material to form a flowable composition in the first container; and (c) user-actuable means for mechanically generating a pressure differential to allow all of the flowable composition which is discharged to be discharged from the first container at any orientation wherein the first container includes a reservoir and an orifice in fluid communication with the reservoir, the orifice acting initially as an inlet for the second material and acting subsequently as an outlet for,the flowable composition; wherein the reservoir comprises an inner collapsible layer distinct from an outer deformable layer of the first container; wherein an applicator is secured to the first container to facilitate the discharge of tic flowable composition from the first container; wherein the applicator includes a valve member of unitary construction operable to control both entry of air into the first container to a position outside the inner collapsible layer and exit of flowable composition from the first container from a position inside the first collapsible layer.
