Abstract

The apparatus comprises an absorbent fibrous mass impregnated with a volatile air sweetening substance. The fibrous mass is covered on the outside by a permeable wall consisting of macromolecular material which is chemically and physically inert to the air sweetening substance. Specif. the permeable wall of macromolecular material comprises a coating film of the fibrous mass in intimate contact with the latter's surface.
