Humidifier reservoir

A water reservoir for an apparatus for humidifying a flow of breathable gas, comprising:

• a reservoir body forming a cavity structured to hold a volume of liquid,
• the reservoir body comprising a conductive portion provided at a lower portion of the reservoir body,
• wherein the conductive portion comprises a thermally conductive material and is adapted to thermally engage with a heater plate to allow thermal transfer of heat from the heater plate to the volume of liquid,
• wherein the conductive portion includes a peripheral interfacing portion structured and arranged to connect the conductive portion to one or more walls of the reservoir body, and
• wherein the peripheral interfacing portion includes an intermediate portion and an end portion, and the end portion is bent so as to be at least inclined with respect to the intermediate portion to reduce a risk of leakage caused by cracks within a critical area of a thickness of the one or more walls due to a presence of a sharp edge at the end portion.
