Dispenser for air treating material Abstract The present invention provides a dispenser for an air treating material from which vapours 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 centre, thereby simultaneously exposing the annular aperture, and which curves convexly outwards by exerting pressure on the periphery, thereby closing the annular aperture again. The dished cover is provided with a spindle in the centre of the inner wall thereof, which spindle traverses a bracket which is made of elastic material and which is secured to two adjacent positions of the dished base, there being present beneath said bracket a pad of absorbent material containing in the interior thereof a plastic sachet which is imperme- able to liquid and which contains a volatile active product in liquid form. For first time use of the dispenser, pressure is exerted on the centre of the cover so that the spindle is pushed downwards and its tip penetrates the pad beneath the elastic bracket. The plastic sachet in the pad is pierced and the active liquid product is absorbed by the pad.
