Abstract
A liquid dispensing device, system and method are disclosed. The liquid dispensing device includes a one-way liquid metering device, comprising a bellows, an inlet valve, and an outlet valve; and a housing, comprising a cavity. The outlet valve is recessed within the cavity and liquid is dispensed from the one-way metering device into the cavity when a proximal portion of a receptacle is inserted into the cavity. Liquid within the bellows is dispensed from the outlet valve when the bellows is compressed, and liquid is drawn into the bellows through the inlet valve when the bellows returns to an expanded state. The system can include a receptacle with a neck extending from a shoulder at the proximal end of the receptacle. The shoulder engages with the at least one surface.
