Various embodiments are generally directed to devices and methods for multi-liquid storage and mixing, such as with a medical liquid packaging device (MLPD), for instance. Some embodiments are particularly directed to an MLPD that includes first and second reservoirs that store separate liquids that may be selectively combined prior to administration to a patient. In one or more embodiments, for example, a device for medical liquid packaging may include a first reservoir and a dispensing port with a second reservoir. In a first state, a flow preventer separates the liquid in the first reservoir from the liquid in the second reservoir. Actuation of an actuator, such as by depression of the actuator, dislodges the flow preventer, allowing fluid communication between the first reservoir and the second reservoir.
