Abstract:
1. 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 top open ends, respectively, and first and second valve seats which are disposed respectively on said first and second internal ports; a conduit unit which is configured to be axially displaceable relative to said internal cap between a normal position and a raised position, said conduit unit including an inner shell including upper and lower surrounding walls which are opposite to each other along the axis, said upper surrounding wall having an internally threaded segment which is in threaded engagement with said conduit unit to permit threaded movement of said inner shell relative to said conduit unit, said lower surrounding wall being configured to be retainingly slidable relative to said internal cap; and a spline mechanism disposed between said conduit unit and said internal cap such that, when said inner shell is turned about the axis for threaded movement relative to said conduit unit, said conduit unit is permitted to be displaced only axially between the normal and raised positions so as to move each of said first and second valves between a respective one of the first and second engaging positions and a respective one of the first and second disengaging positions.
