A fluid dispenser device adapted for mounting at an inner top open end of an inner container and an outer top open end of an outer container that coaxially surrounds the inner container along an axis, said fluid dispenser device comprising:
- an internal cap adapted to cover the inner and outer top open ends, and having first and second internal ports which are configured to be in fluid communication with the inner and outer open ends, respectively, and first and second valve seats which are disposed respectively on said first and second internal ports;
- a conduit unit disposed to be angularly displaceable about the axis, and configured to be axially displaceable along the axis, said conduit unit including
- a first conduit having a first communicating port which extends along the axis, and which is disposed downstream of said first internal port such that said first valve seat permits fluid communication between said first internal port and said first conduit, and a first outlet which is disposed downstream of said first communicating port,
- a second conduit having a second communicating port which is disposed radially of said first communicating port, and which is disposed downstream of said second internal port such that said second valve seat permits fluid communication between said second internal port and said second conduit, and a second outlet which is disposed downstream of said second communicating port,
- a first valve disposed on said first communicating port, and configured such that, when said conduit unit is displaced from a normal position to a dispensing position as a result of angular and axial displacement thereof, said first valve is displaced from a first engaging position, where said first valve is engaged with said first valve seat to thereby interrupt fluid communication between said first internal port and said first communicating port, to a first disengaging position, where said first valve is disengaged from said first valve seat to thereby permit fluid communication between said first internal port and said first communicating port, and
- a second valve disposed on said second communicating port, and configured such that, when said conduit unit is displaced from the normal position to the dispensing position, said second valve is displaced from a second engaging position, where said second valve is engaged with said second valve seat to thereby interrupt fluid communication between said second internal port and said second communicating port, to a second disengaging position, where said second valve is disengaged from said second valve seat to thereby permit fluid communication between said second internal port and said second communicating port;
- and
- a nozzle head including a skirt which is disposed to surround said conduit unit about the axis, and which is engaged with said conduit unit such that said skirt is angularly and axially movable with said conduit unit relative to the axis, and a head which has first and second nozzles which are disposed downstream of said first and second outlets, respectively, and which extend in a same direction.
