Flameless energized emanator

Abstract

An energized assembly to disseminate a treatment agent in vapor phase to a local environment. The assembly includes an emanator element to hold treatment agent, and a flameless energizing source to facilitate volatization of the treatment agent. Preferred embodiments operate for a period of time of between about 4 and 8 hours, and can then be discarded. Typically, a housing associates the treatment agent and the energizing source. Embodiments may sometimes include one or more of: a gas-tight boundary element, a thermal transfer element, a trigger mechanism, a safety mechanism, a termination mechanism, a time-delay mechanism, solidized treatment agent to avoid spills, and a sequestering arrangement.
