1. A water reservoir for use with a respiratory pressure therapy (RPT) device for pressurising breathable air to treat a respiratory disorder in a patient, the water reservoir comprising:
a water reservoir base configured to hold a volume of water to be used for humidification of the breathable air;
a water reservoir lid connected to the water reservoir base, the water reservoir lid including a retainer configured to engage with a corresponding portion of a water reservoir dock associated with the RPT device, thus securing the water reservoir to the water reservoir dock, the water reservoir having a spring, at least a portion of the water reservoir lid with the retainer being movable relative to the water reservoir base against the bias of the spring; and
a handle portion configured to receive a downward force applied by the patient to 1) cause relative movement between the portion of the water reservoir lid and the water reservoir base and 2) disengage the retainer against the bias of the spring, thus allowing removal of the water reservoir from the water reservoir dock.
