(57) Apparatus for dispensing of at least two different fluid compositions, said apparatus
comprising: a cartridge (37) having therein plural separate chambers (4, 6) for containing
separate fluid compositions to be dispensed; a neck portion (8) provided at a discharging
first end of said cartridge; plural separate passageways (10, 12) extending through
said neck portion, each said passageway opening into a separate respective said chamber,
the arrangement being such that the simultaneous application of pressure to the fluid
compositions in each said separate chamber causes, in cooperation with a back pressure
from the restriction of said passageways, compression of the fluid compositions, and
thus causes the fluid compositions to be extruded in a predetermined ratio through
the respective said passageways; and means for controlling the flow of the fluid compositions
through the respective said passageways, for preventing run-on of the ' fluid compositions
through said respective passageways due to decompression of the fluid compositions
upon removal of the pressure, and thereby for preventing dispensing of the fluid compositions
through said respective passageways in a ratio other than said predetermined ratio,
said controlling means comprising a valve member (18) having therethrough plural passage
portions (22, 24), said valve member being mounted within said neck portion for movement
with respect thereto between an open first position, whereat said passage portions
I are aligned with respective said passageways, thereby permitting extrusion of the
fluid compositions through said passageways in said predetermined ratio, and a closed
second position, whereat said flow portions are out of alignment with said respective
passageways and said passageways are blocked by said valve member, thereby preventing
any passage of the fluid compositions through said passageways.
