A respiratory pressure therapy device comprising a pressure generator for supplying a flow of air at positive pressure and an apparatus for humidifying the flow of air integrated in the respiratory pressure device, the apparatus for humidifying the flow of air comprising: a dock comprising a dock cavity having a top portion and a bottom portion, the bottom portion having a heater plate located thereon; a reservoir comprising a chamber, the dock being configured to receive the reservoir, and the dock cavity being configured to retain at least a portion of reservoir, wherein, when the dock receives the reservoir, the chamber is in fluid communication with the flow of air; wherein the reservoir comprises: a base structured to hold a volume of liquid and including a conductive portion configured to be in thermal engagement with the heater plate in use; a lid pivotably connected to the base by hinges to allow the reservoir to be convertible between an open configuration and a closed configuration; a resilient portion configured to form a seal between the base and the lid when the reservoir is in the closed configuration, wherein the resilient portion is compressible; and an upper handle located on the lid and a lower handle located on the base, wherein the upper handle and the lower handle are located away from the hinges such that, when a patient holds the reservoir by the upper handle and the lower handle, the patient can impart forces onto the reservoir compressing the resilient portion, which pushes the lid and the base towards each other, wherein the height of the water reservoir when the resilient portion is compressed is slightly less than the height of the dock cavity to enable the insertion and/or removal of the water reservoir into and/or from the dock cavity, to facilitate coupling of the reservoir to the dock and/or to remove the reservoir from the dock. a dock comprising a dock cavity having a top portion and a bottom portion, the bottom portion having a heater plate located thereon; a reservoir comprising a chamber, the dock being configured to receive the reservoir, and the dock cavity being configured to retain at least a portion of reservoir, wherein, when the dock receives the reservoir, the chamber is in fluid communication with the flow of air; wherein the reservoir comprises: a base structured to hold a volume of liquid and including a conductive portion configured to be in thermal engagement with the heater plate in use; a lid pivotably connected to the base by hinges to allow the reservoir to be convertible between an open configuration and a closed configuration; a resilient portion configured to form a seal between the base and the lid when the reservoir is in the closed configuration, wherein the resilient portion is compressible; and an upper handle located on the lid and a lower handle located on the base, wherein the upper handle and the lower handle are located away from the hinges such that, when a patient holds the reservoir by the upper handle and the lower handle, the patient can impart forces onto the reservoir compressing the resilient portion, which pushes the lid and the base towards each other, wherein the height of the water reservoir when the resilient portion is compressed is slightly less than the height of the dock cavity to enable the insertion and/or removal of the water reservoir into and/or from the dock cavity, to facilitate coupling of the reservoir to the dock and/or to remove the reservoir from the dock. a base structured to hold a volume of liquid and including a conductive portion configured to be in thermal engagement with the heater plate in use; a lid pivotably connected to the base by hinges to allow the reservoir to be convertible between an open configuration and a closed configuration; a resilient portion configured to form a seal between the base and the lid when the reservoir is in the closed configuration, wherein the resilient portion is compressible; and an upper handle located on the lid and a lower handle located on the base, wherein the upper handle and the lower handle are located away from the hinges such that, when a patient holds the reservoir by the upper handle and the lower handle, the patient can impart forces onto the reservoir compressing the resilient portion, which pushes the lid and the base towards each other, wherein the height of the water reservoir when the resilient portion is compressed is slightly less than the height of the dock cavity to enable the insertion and/or removal of the water reservoir into and/or from the dock cavity, to facilitate coupling of the reservoir to the dock and/or to remove the reservoir from the dock.
