Abstract: The invention relates to improvements in or relating to containers and in particular to a refill for an air freshening or purifying device utilizing a gel fragrance or other gel composition and to a device comprising a base container and a refill. The invention specifically comprises a refill for use with an air freshening or purifying device, said refill comprising a refill container having a gel receiving surface and an opposing rear surface, the gel receiving surface having at least one recess in which is contained a gel composition, wherein the profile of the rear surface inversely corresponds to the profile of the gel receiving surface such that it is provided with at least one projection inversely corresponding to the said recess in the gel receiving surface.

Abstract: The invention relates to improvements in or relating to air freshening or purifying devices in the form of sheets. The invention therefore provides an air freshening or purifying sheet comprising a substrate in the form of a sheet having opposing surfaces, wherein a releasable adhesive is applied to at least one region of one of said surfaces, and at least another region of one or both of said surfaces being coated with a layer of an air freshening or purifying composition in which the said composition is a gel composition resulting from the cross-linking in situ, of a homopolymer or copolymer in the presence of a perfuming, deodorising or insecticidal base.

Abstract: A fragrance emanating device for freshening atmospheric air has (i) a closed container for accommodating a liquid fragrance composition in its interior, (ii) an emanator having a surface open to the ambient air for evaporation of the liquid fragrance composition, and (iii) a conduit linking the emanator surface with the liquid fragrance composition in the interior of the container. The components of the device are so dimensioned that, in use, thermal expansion of air and/or liquid in the container, resulting from an increase in temperature, causes a portion of the fragrance composition to travel along the conduit from the container to the emanator surface, and thermal contraction of the air and/or liquid in the container, resulting from a decrease in temperature, causes air from the atmosphere to enter the container via the conduit.
