Abstract
The present invention provides a dispenser for an air treating material from which vapors are released into the ambient air through an annular aperture from a round dished base, said dispenser comprising a round dished cover made of an elastic material the top of which curves concavely inwards by exerting pressure on its center, thereby simultaneously exposing the annular aperture, and which curves convexly outwards by exerting pressure on the periphery, thereby closing the annular aperture; a spindle in the center of the inner wall of the dished cover which spindle traverses a bracket secured to two adjacent positions of the dished base; a pad of absorbent material positioned beneath the bracket containing in the interior thereof a plastic sachet which is impermeable to liquid and which contains a volatile active product in liquid form; the exertion of pressure on the center of the cover pushing the spindle downwards so that its tip penetrates the pad beneath the elastic bracket and pierces the plastic sachet in the pad thereby permitting the active liquid product to be absorbed by the pad.
