ABSTRACT:
Disclosed is an evaporator for volatile active substances such as insecticides or perfumes. It has a housing containing ports through which the active substance emerges. The housing is made up of at least two housing sections which are movable about a hinge axis. At least one receiving section for an active substance container is provided and includes at least one opening device for opening the container. The operating condition is indicated, and there is a further container holding an indicator fluid which is opened when the evaporator is in use so that the indicator fluid can evaporate over the time period during which the active substance is depleted. A mounting member positions the indicator fluid container between the two housing sections, and one of the sections incorporates an opening behind which the indicator fluid container is positioned so that it can be viewed from the outside of the housing to determine the operating condition of the device, while the container holding the active substance cannot be viewed from the outside.
