Abstract
Containers which hold a flowable composition are sealed by applying a material which in contact with the flowable composition forms a protective sealing layer in the area requiring a seal. An improved container assembly is disclosed comprising a cartridge containing a flowable composition and a piston inserted into one end of the cartridge to express the flowable composition therefrom, wherein the gap between the cartridge and the piston is sealed by a protective layer produced by reaction of the flowable composition and material applied to the surface of the flowable composition.
