Abstract:
1. A dispensing device comprising: a reservoir containing a fabric cleaning fluid, one or more dispensing orifices in fluid communication with the reservoir, and a movable platform movable by means of a screw mechanism, wherein the screw mechanism comprises a first threaded shaft having internal threads, and a second threaded shaft having external threads configured to engage the internal threads of the first threaded shaft, wherein the second threaded shaft is fixed to the movable platform, wherein rotation of the screw mechanism axially advances the movable platform against the stored fabric cleaning fluid thereby dispensing a metered dose of the fabric cleaning fluid from the reservoir, wherein the second threaded shaft is configured to rotate without rotating the movable platform and is configured to move in an axial direction with the axial advancement of the movable platform, and wherein the reservoir and the movable platform are non-circular in cross section to resist rotation of the platform relative to the reservoir.
