Abstract: An insecticidal evaporator is described which comprisesI a liquid composition containingA. 40 to 90% by weight approximately calculated on the total weight of the composition of a volatile insecticidal ester of phosphoric acid the vapor pressure of which is at least 10.sup..sup.-3 Torr at 20.degree.C;b. at least one first additional organic liquid compound having a vapor pressure less than or equal to that of the volatile insecticidal ester;C. at least a second additional organic compound miscible or soluble in the mixture of the volatile insecticidal ester and of the first additional compound;Ii. a fibrous mass absorbent for the said composition I, and impregnated by the same; andIii a diffusion layer covering at least a part of the surface of the said fibrous mass, the remainder of the surface of the fibrous mass being covered by an envelope impermeable to the said composition.

Abstract: A container and hanging device therefor is disclosed wherein the container has a support wall having the hanging device mounted thereon and a contiguous side wall extending from the support wall. The container is adapted to be supported on a support member, for example the inside of a toilet flush tank, by the hanging device, which consists of a generally U-shaped clip having a bight portion and a pair of spaced legs, which clip is pivotally mounted on the support wall of the container for movement between a storage position, wherein the bight portion of the clip is adjacent and parallel to the side wall of the container, and a support position, wherein the bight portion of the clip extends parallel to the support wall and at least a part of the bight portion extends beyond the container so that one of the legs of the clip is in spaced relation to the side wall of the container for receiving therebetween the support member or wall of the flush tank so as to suspend the container therefrom.
