<p>A flowable material dispenser comprising an enclosed volume casing (1b) having an upper (1c) and lower (1a) end enclosing a flowable material. There is a spigot (3) for withdrawal of the flowable material, and a pliable pouch (4) disposed within the casing. The pouch (4) is in communication with the atmosphere such that it expands to fill the void of the material dispensed from within the casing. The pouch thus isolates the flowable material remaining in the casing from the atmospheric air that enters the casing to replace the material which has been dispensed.</p> |
