Abstract

The active material in the form of a solid block, or impregnated porous carrier, is surrounded by a container e.g. of polypropylene or card, in the walls of which are one or more openings which are closed by a sliding shutter or shutters. The size of the opening(s), and hence the rate at which the volatile material is released, is controlled by the position of the shutter(s). This may be pre-calibrated to give a desired concnentation programme.
