Abstract
A torch has a fuel container with a reservoir and a top cover. The top cover defines a first wick passage, a first fill hole, and a guide slot. A fire bowl is positioned atop the fuel container and defines a second wick passage, a second fill hole, and a guide member. At least one open rotational position is allowed between the fuel container and fire bowl such that the first and second fill holes are aligned to allow fluid into the reservoir via the fill holes. At least one closed rotational position is allowed between the fuel container and the fire bowl such that the first and second fill holes are out of alignment substantially blocking fluid flow into or out of the reservoir via the fill holes.
