Abstract
An actuator assembly is disclosed which can dispense chemicals, such as insect control ingredients, from an aerosol container. The actuator assembly is mountable to the aerosol container and includes a solid plug that, upon initial activation, will be caused by the pressure of the chemical in the aerosol container to move to an unsealed position. Movement of the plug is retarded by a frictional engagement of the plug with an associated passage/conduit. The device can be manually activated, but is designed so that thereafter it does not need to be manually held open. The consumer has time to leave the room before spraying begins, and does not need to be present in the room before spraying has finished.
