Abstract
The burner assembly includes a canister molded from a synthetic thermoplastic or thermosetting material and having a neck portion defining an opening for introducing a combustible liquid into the canister and a metal cap member for covering the canister opening and holding a wick. The cap member has an annular, inner flange which extends downwardly through the canister opening and fits in sealing engagement with the inner wall of the canister neck portion and an annular, peripheral outer collar which fits over and is crimped onto a laterally outward extending annular lip on the upper rim of the canister neck portion to sandwich or capture the upper rim between the inner flange and the outer collar.
