Abstract:
A packaged device for the delivery of products, comprising:at least one liquid reservoir for containing at least one product, said product comprising an active ingredient; and a product delivering means comprising a spray arm, at least one product dispensing opening, so that in operation, the product is conducted from said at least one liquid reservoir, through the spray arm, to the product dispensing opening from which it is dispensed, wherein said product delivering means comprises an electrically driven pump which is provided with an electrical power source, said power source comprising at least one electrical battery, the battery being housed in the package and wherein said pump is reversible so that it can either dispense said product from said at least one reservoir, or suck said product back into said at least one liquid reservoir and wherein said at least one reservoir is releasably connected to the pump through a liquid-tight vent and fluid transfer fitment, said fitment comprising: (a) a transfer check valve for allowing passage of liquid from said at least one reservoir to the pump, and (b) a transfer venting valve for allowing air to displace the liquid when said liquid exits said at least one reservoir, both valves having an inherent sealing pressure created by the static pressure of the liquid within the reservoir; and (c) a probe member in fluid communication with said pump, wherein said liquid product flows by gravity through said transfer check valve and said probe member when said probe member is inserted into said fluid transfer check valve.
