Abstract
Disclosed herein are mats for dispensing volatile materials. A mat of the present invention includes a moat on an upper surface of the mat defining a first mat portion and a second mat portion, preferably connected at the bottom of the moat. Both portions are impregnated with the same or different volatiles. The moat is formed by pressing the upper wall of the mat with a hot forming die. While pressed against the upper wall, the hot die melts the mat material leading to the close of the pores in the material and as a result, a barrier along moat walls is formed. The moat and barrier act to prevent or reduce bleeding of the volatiles between two portions of the mat. The mat provides for both instant burst of volatile and then a sustained vaporization of volatile. Methods for making and using the mat are also disclosed.
