(57) A cleaning chemical dispensing system comprising : a liquid chemical additive having
a predetermined viscosity; a mop bucket (2); a mop wringer (6) provided on the mop
bucket; a first indicator (2a) which indicates a first volume of cleaning liquid in
the mop bucket; and a secondary reservoir (15) for the liquid chemical additive, the
secondary reservoir (15) being at a position spaced above the first indicator (2a),
and having a base (115), one or more upstanding walls (116) continuously contiguous
with and fully surrounding the base (115), an opening (117) opposite the base (115)
for pouring the liquid chemical additive into the secondary reservoir (15), a metering
orifice (17) formed in the base (115), and a second indicator (118) indicating a second
volume for the liquid chemical additive which corresponds to the first volume of the
mop bucket (2) so as to provide a required ratio of liquid chemical additive to cleaning
liquid, the metering orifice (17) being dimensioned to correspond to the predetermined
viscosity of the liquid chemical additive, so that the liquid chemical additive can
be poured into the secondary reservoir (15), via the opening (117), up to the second
volume indicated by the second indicator (118) before any significant amount of the
liquid chemical additive passes through the metering orifice (17).
