The burner assembly include a container having a neck with a central opening through which a liquid fuel is introduced into the container and a one-piece cap removably mounted on the container neck. The cap has a crowned central portion with a central opening through which a tubular wick holder made from a crimpable material extends. The wick holder has an outer end through which the exposed outer end of a wick extends and an inner end including a radially outwardly extending flange which engages a first seating portion on the inner surface of the cap and surrounding the cap opening. The wick holder also has an intermediate portion including a crimped area which engages a second seating portion of the outer surface of the cap and surrounding the cap opening. This crimped area cooperates with the inner flange on the wick holder to hold the wick holder in place on the cap.
