Abstract:
1. A device for dispensing fluid and semi-dense substances packaged in flexible sealed sachets, comprising two generally rigid valves mutually connected at one end and delimiting an interstice therebetween for housing at least one flexible sachet having an openable side protruding from the other end of said two valves in order that, when in use, mutual approaching of said two valves produces a progressive squeezing of the at least one sachet and the dispensing of the substance contained therewithin following opening of said openable side; and wherein said two valves are provided with unidirectional positioning and retaining means to prevent their mutual opening, said unidirectional positioning and retaining means including a pair of indented transverse pins carried by one of said valves in proximity to said end thereof opposite to said connecting end to the other valve, and a pair of holes correspondingly provided to the other valve for irreversible engagement of said indented pins.
