ABSTRACT:
A dispenser for solid air treating materials having a base container for the material and a displaceable cover. The base contains a socket which is adapted to receive prongs which project from the underside of the cover and to engage the prongs so as to permit the positioning of the cover in different vertically spaced positions with respect to the container and thereby to effect a corresponding release of air treating material.
