Abstract: Systems, methods, and computer program products for configuring and managing chemical dispensers (41). A mobile device (18) scans for and wirelessly connects to dispensers (41) within range of the wireless device (18). The wireless device (18) downloads one or more configuration files from a database (28) of dispenser configuration files for configuring the dispenser (41). In response to the user selecting a configuration file, one or more configuration parameters defined by the configuration file are uploaded into the dispenser (41). The wireless device (18) may then step the user through setup of the dispenser (41) using data in the configuration file. The mobile device (16) may further determine the location of the dispenser (41), and upload the location to the database (28). The database (28) may then associate the dispenser (41) with the location as well as keep track of how the dispenser is configured.

Abstract: A pump comprising a piston in communication with a valve chamber provided with a first valve seat and a second valve seat, and a resilient valve element comprising a first tapered portion, a second tapered portion and a flange portion extending from a periphery of the first tapered portion, in which the flange portion co-operates with the first valve seat to form an inlet valve, and the second tapered portion co-operates with the second valve seat to form an outlet valve, and in which negative pressure applied to the flange portion by the pressure means in use lifts it from the first valve seat, and positive pressure applied to the first tapered portion by the piston in use lifts the second tapered portion from the second valve seat.

Abstract: A liquid dispenser has a support (2) for a collapsible container (28) and a connector (60), including a stopper (8), to connect an actuator of the liquid dispenser to the collapsible container (28). The stopper (8) is movable from a first position to a second position in which the stopper (8) connects to the collapsible container (28), whereby operation of the actuator causes the delivery of liquid from the dispenser. The collapsible container (28) is a flexible pouch (38) having a valve (52) which, upon movement of the stopper (8) into its second position, is moved from a first position preventing loss of liquid from the pouch (38), into a second position in which the stop valve (52) allows the delivery of a quantity of liquid from the dispenser.

Abstract: A dispensing device for dispensing a measured quantity of a concentrated cleansing liquid into a spray bottle or any other suitable receptacle, is provided with means for pumping the measured quantity of the liquid from a source into a holding reservoir. The dispensing device includes inhibiting means for preventing the interruption of a priming stroke as the liquid is pumped from the source into the reservoir and for preventing the interruption of a delivery stroke as the liquid is pumped from the reservoir to the receptacle. The inhibiting means includes a pivotable lever having an arcuate rib engaged by a pair of locking members arranged to engage opposite tracks of the arcuate rib.
