ABSTRACT:
A package and dispenser for a volatile air-treating or air-freshener material includes a container open at its upper end. A first layer of a porous material is permanently secured to the open end of the container and a second layer of a non-porous material is removably secured to the container over the porous layer. When it is desired to use the container to release vaporized aif-freshener material, the second layer is removed and the remaining porous layer allows the air-freshening vapor to permeate therethrough while at the same time retaining the remaining non-volatized material within the container.
