A device is disclosed for containing and dispensing flowable materials contained in a material handling unit which is located at least in part within an outer container. The material handling unit includes a first, relatively rigid portion having a nozzle affixed to one end thereof and a readily reshapable bladder affixed to the other end thereof, with the nozzle having a one-way check valve permitting ejection of the contents therefrom. The outer container admits air into the space between the containers to thereby cause selective expellation of the contents of the material handling unit without direct manual contact by a user with the device.
