Systems and methods for delivering a composition

A cartridge assembly, comprising:

• a container including a container body and an elastomeric member disposed within the container body to retain a composition within the container;
• a cartridge chassis having a plurality of coupling members distributed about a perimeter of the cartridge chassis, each coupling member of the plurality of coupling members is positioned to be received by a coupling interface of a delivery device, the cartridge chassis including a container clip at least partially surrounding the container body to secure the container in a fixed position relative to the cartridge chassis, a first coupling member of the plurality of coupling members including a longitudinal positioning feature positioned to engage a first corresponding feature of the coupling interface of the delivery device to prevent longitudinal movement of the cartridge chassis relative to the coupling interface;
• and
• the first coupling member is formed at a distal perimeter portion of the cartridge chassis and includes a living hinge, the first coupling member having an extended position when the cartridge chassis is separated from the delivery device and a compressed position when received by the coupling interface, the living hinge being oriented to exert a force on the delivery device when received by the coupling interface.
