Abstract
A system for the preservation, transportation and dispensing of dyes provides for a combination of a hollow reservoir having at least one deformable wall so that its internal volume can vary from a maximum to a minimum substantially close to zero, and an opening for the connection of the reservoir to a dye-dispensing circuit; the reservoir is airtight so that its internal volume corresponds to the volume of dye contained therein in essentially any condition of use.
