Abstract: Controlled sanitizing by dispensing a germicide, such as a disinfectant, antibacterial solution or cleansing agent at intervals. A system can include a housing sized to seat an aerosol can and a control circuit that operates to momentarily open a valve on the aerosol can through action of a gear system upon an aerosol delivery tube. A sensor responds to displacement of the delivery tube to deliver state signals to the control circuit. The control circuit prevents action of the gear system in the event that the state signals fail at least one prescribed condition. A method registers at least the displacement of the delivery tube via the sensor and prevents subsequent displacements and hence subsequent sanitizing in the event that the sensor has not registered at least the displacement of the delivery tube. The method ensures that a suitable aerosol can has been properly loaded in the dispenser.

Abstract: A large size aerosol container (10?) dispensing a fluent material. A generally cylindrical can body (12?) is fabricated from a steel sheet and has a relatively thin sidewall thickness of between 0.004 inches and 0.010 inches depending upon the weight of the steel sheet from which the container is made. The can body has beads (30) formed at regular intervals substantially its length. The beading adds structural strength to the container so the container is not damaged by handling during manufacture of the container, will not collapse during vacuum filling, and cannot be crushed by hand before the container is filled. The container can withstand a vacuum of at least 23 inches of Mercury without collapsing. A valve assembly (14?) includes a spray valve (20) for dispensing the fluent material stored in the container. The container is filled with the fluent material and a propellant stored in the container under pressure.

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 burstable barrier and an extrudable (e.g. paste) plug. Upon initial activation, the pressure from inside of the container presses the burstable barrier which in turn presses the paste plug to cause at least a portion of the plug to move to a position where it is visible and provides a cue that a delay period has started. The device can be manually activated, but is designed so that thereafter it does not need to be manually held open. The user has time to leave the room before spraying begins, and does not need to be present in the room before spraying has finished.

Abstract: A gas adsorption material containing a desired quantity of gas is placed in a pressurized container along with a product to be dispensed, and as pressure in the container is depleted during use, stored gas is released into the container to maintain pressure in the container within a predetermined range. The material may be in contact with the product, or it may be isolated from the product, and is known as a pressure swing adsorption (PSA) system, wherein adsorption of gas into the material occurs at a high pressure, and desorption of gas from the material occurs at a low pressure. Such devices are capable of storing under pressure a volume of gas 18 to 20 times the volume of the material. A preferred adsorbent gas storage material is granular activated carbon, or a carbon fiber composite molecular sieve (CFCMS).
