摘要： A dispensing device for a vaporizable material is disclosed which has a container (1) for holding a vaporizable liquid, the container including an opening therein; and a porous wick having a first section (3a) comprised of a material with a predetermined pore size and a second section (3b) comprised of a material with a predetermined pore size that is greater than that of the first section, positioned so that a lower region of the wick will be in contact with the liquid to be held by the container and an upper region of the wick is exposed to the ambient air to dispense the vaporizable liquid. The opening in the container is substantially sealed by the wick, and the second section of the wick surrounds the portion of the wick that is exposed to the ambient air. Also disclosed is a method of dispensing a vaporizable material from a container. The method comprises positioning a porous wick in the container with a lower region in contact with the liquid in the container and an upper region extending from the container; activating the release of vaporizable material from the wick (3) to the ambient air; and deactivating the release of vaporizable material from the wick (3) to the ambient air; wherein the wick (3) has a first and a second section (3a, 3b) of different pore sizes, the pore size in the first section (3a) being smaller than the pore size in the second section (3b), such that during deactivation, due to the higher equilibrium rise within the first section of the wick than in the second section, the first section becomes saturated whereas the second section does not, and during activation, due to a lower rate of wicking in the first section than in the second section causes produces an initial "spike" effect in the emission from the wick as initially material is emitting from both first and second sections (3a, 3b) until the first section (3a) becomes depleted.

摘要： An air treatment control device has a useful life indicator of an air treatment chemical dispenser. The indicator device has a well with a volatile indicator material positioned therein. The well's cavity is configured to achieve clumping of the remaining indicator material as some volatizes due to capillary attraction. This presents a shrinking display that can be coordinated with the level of use of the air treatment chemical dispenser.
摘要翻译：空气处理控制装置具有空气处理化学品分配器的使用寿命指示器。指示器装置具有其中放置有挥发性指示剂材料的孔。井的腔被配置成实现由于毛细管吸引引起的一些挥发物而残留的指示剂材料的结块。这呈现出缩小的显示，可以与空气处理化学品分配器的使用水平相协调。
