Abstract: Device for dispensing fluid and semi-dense substances in flexible sealed sachets including two valves mutually connected at one end and delimiting an interstice for housing at least one sachet in order that, in use, the mutual closure of the two valves produces the squeezing of the sachet and the dispensing of the substances contained therewithin following its opening.
