• a reservoir configured to contain a pre-vapor formulation, the reservoir being refillable, and the reservoir including,
• an opening, the opening including,
• a valve, the valve including a spring-loaded disk and a gasket, and
• a first interlocking ring at the opening, the first interlocking ring including a groove, a protrusion, or both a groove and a protrusion, the first interlocking ring configured to connect to a second interlocking ring attached to a refill container.

An electronic vaping device comprising:

• a housing extending in a longitudinal direction;
• a reservoir configured to contain a pre-vapor formulation, the reservoir in the housing, the reservoir being refillable, and the reservoir including,
• an opening, and
• a first interlocking ring at the opening, the first interlocking ring including a plurality of grooves, a plurality of protrusions, or both a plurality of grooves and a plurality of protrusions spaced about a circumference of the first interlocking ring, the first interlocking ring configured to connect to a second interlocking ring attached to a refill container;
• a heater in fluid communication with the reservoir;
• and
• a power supply configured to supply power to the heater.
