摘要：
A scent dispenser is provided which comprises a cylinder having a cylinder chamber for receiving a hollow piston which includes a piston body that is closely fitted to the cylinder chamber and is slideable therein, upward to a fully extended position and downward to a fully compressed position. The piston body also includes a cylindrical piston chamber having an opening at a bottom end of the piston body, which body is sized and shaped to receive a scent cell therein. The piston further includes a cover attached to or integral with an upper end of the piston body. The scent cell may be in the form of a substrate of nonwoven fibrous material capable of allowing air to flow readily through the scent cell and through a volatile scented substance contained therein. The scent cell may further comprise a coating material capable of reversibly absorbing or adsorbing the volatile scented substance, while allowing air to flow readily through the scent cell. The coating material covers or coats the substrate and may comprise a substantially hydrophilic foam.
