Abstract: This invention provides a spill-proof dispersion device for dispersing volatile liquids, comprising a receptacle for containing volatile liquid therein and having an opening, at least one wick having an end placed in contact with the volatile liquid in the receptacle and for delivering the volatile liquid, and a diffuser in firm connection to the other end of the at least one wick and having a body with a surface from which the volatile liquid delivered from the wick is dispersed into an environment. The diffuser comprises a base located at its bottom and a sheath having a screwed outer surface and is sleeved tightly on an outer surface of the base; the base and the sheath are to be inserted into the opening of the receptacle such that the diffuser is engaged with the receptacle in an air-tight manner; and the wick runs through the base and the sheath.
