A combined container and dispenser for dispensing a volatile product such as air freshener or insecticide by volatilization of the product from within the container includes an annular cup having a threaded axial hub and a peripheral flange defining a seal surface. A spheroidal cap has a threaded axial stem arranged for progressive threaded coupling with the hub and an annular seal ring disposed at the outer edge of the cap and arranged to sealingly engage the seal surface of the cup to form a sealed container therewith. A cellulose pad impregnated with a volatile product is disposed on ribs provided on the hub in interference relationship therewith and has its outer edge supported by vane-like support members on the outer portion of the cup. A flange is provided on the distal end of the stem within a counterbore formed in the bottom of the cup and hub to limit the extent to which the container may be opened by unscrewing of the cap from the cup. The flange may be provided by heat forming, spin welding or insertion of a flanged plug into the stem.
