Abstract
A volume expansion feature for a fluid reservoir is provided, the volume expansion feature comprising a central recess, a plurality of channels extending from the central recess, where the central recess and the channels are positioned at least in part in a recessed surface profile. The recessed surface profile is reversibly moveable from a first inwardly directed configuration, to a second outwardly directed configuration. The central recess and the channels are configured to impart an inward bias to maintain the recessed surface profile in the first inwardly directed configuration under standard loading of the fluid reservoir. Upon increased pressure within the fluid reservoir, the recessed surface profile extends to the second outwardly directed configuration, thereby increasing the volume of the fluid reservoir.
