ABSTRACT:
A passive dispenser of volatile liquid fragrance composition from a container thereof. The container has an orifice at its bottommost point and an isotatic hydrophobic polypropylene membrane covering the orifice. The membrane permits passage of the liquid fragrance composition therethrough in the liquid phase in order to enable the composition of the liquid transmitted through the membrane to be substantially the same as that of the liquid within the container.
