Methods, apparatuses and systems are disclosed including a method of filling a container with substantially only a liquid. The method can include the removal of a gas from the container prior to, during or after the filling of the container with the liquid. According to one embodiment, the container includes an inner liner and a lid. The method includes providing a volume defined by at least the inner liner and the lid of the container. In such embodiment, the liquid can initially be contained within a first portion of the volume and a remaining portion of the volume can contain a gas. The method can include removing substantially all the gas from the volume via one or more ports that communicate with the volume while retaining substantially only the liquid within the volume.

A fluid sprayer includes a pump and an electrostatic module configured to provide an electrostatic charge to spray fluid. The electrostatic module is electrically connected to a conductive component of the fluid sprayer, such as a fluid displacement member, fitting, cylinder, or spray tip, to charge the spray fluid via the conductive component. The fluid is electrostatically charged prior to exiting the fluid sprayer.

Apparatuses for dispensing household fluids including a handheld device or wand including a pump for dispensing one or more household fluids at a rate and for a time sufficient to dispense a pre-determined or variable amount of the fluids into an appliance, and to methods for making and using same. Apparatuses for dispensing pool chemicals including pool chemical containers, pool chemical sensors, and pumps for introducing pool chemical into pool water on a periodically basis.

A dispensing system for heating and dispensing a food substance in a liquid state includes a portable dispensing unit including housing including a reservoir for holding a food substance, a heater operable to heat the substance to an operating temperature for producing a liquid, and a pump for dispensing the liquid via a dispensing tube and spray nozzle. A manually activated actuator operates to initiate the dispensing cycle. Control circuitry associated with the dispensing unit monitors the liquid temperature and controls operation of pump and unit. The dispensing unit may be powered by a rechargeable battery. A charging base provides a dock for recharging the battery of the dispensing unit. The pump may include an auto-reverse feature to draw the liquid back into reservoir when not dispensing the liquid for preventing clogs in the dispensing system.
