ABSTRACT:
New blanket cleaning liquid flows from an inverted bottle 16 inserted through a hole 7 in the upper arm 8 of a U-shaped bracket 5 to a cleaning bath 2 via a spring biased push valve 20 in the bottle, a supply pool 9 in the lower arm of the bracket beneath the pouring mouth of the installed bottle, and a three-way control valve A. The latter may selectively communicate the supply pool with the cleaning bath in a delivery mode, or communicate the bath with a used liquid storage bottle 28 in a discharge mode. The bath is vertically disposed at a position proximate that of the bracket, whereby the liquid level in the bath is automatically maintained at the same level as the new cleaning liquid in the supply pool, which in turn is maintained at the height of the pouring mouth lip of the bottle 16.
