Sprayer for fluid product in which a hand-actuated trigger forces a hollow piston mounted to move in vertical reciprocating fashion in a stationary tubular accumulator, against the compression of a spring. The product is forced upward and out through a swirl chamber adjacent the spray nozzle. Additional product is siphoned up into the accumulator by the partial vacuum created by the return of the piston to its rest position. Alternative embodiments, including both a vertically and horizontally directed sprayer, feature an annular flexible flange seating against an annular skirt below a swirl chamber, which keeps air out of the product chamber and deflects inwardly to release product under pressure. Additionally, a horizontally-directed spray-head may be attached to the vertical trigger sprayer for the purpose of converting the latter to a horizontal sprayer. Further embodiments comprise modification of the annular flexible flange including separate flange-type components which may be force-fitted into the accumulator top, and are constructed to tangentially seal against the annular skirt and deflect to release product. A dome and stopper structure may be used to replace the annular flexible flange, which acts as a diaphragm flexing under pressure to release product. Due to the flexible flange which deflects to allow the product to enter the swirl chamber, the sprayer may be used in an inverted position, provided a centrally-disposed siphon tube is removed.

A docking station and bottle system 23 including a filling head 20 and bottle 22 which have a head interconnect 86 and a bottle interconnect 90, respectively, for fastening the bottle 22 to the filling 20 head in order to prevent spillage. The bottle interconnect 90 includes a fluid port 106 and a vent port 104 which are simultaneously opened from a closed position in order to allow the filling head 20 to draw concentrated fluid from the bottle 22 and mix the concentrated fluid with a diluting fluid such as water before being dispensed from a filling head nozzle 52. The bottle 22 includes identifying indicia 158 for purposes of tracking utilization of the bottle and the concentrated fluid contained therein. An information storage system 170 is associated with the bottle and filling head in order to provide records of such concentrated fluid utilization. A wall mounted docking station 200 including one or more filling heads 20 is also provided for. A refill head is further provided for refilling bottle 22.
