Abstract
A device for introducing volatile fluid into a local environment. A volatile fluid chamber holds a quantity of volatile fluid in a solidified form to permit sustained release of volatile fluid in vapor form. A device may cause release of volatile fluid vapor into the local environment as a steady stream or intermittent puff. Gas discharge from the device may be urged by way of a vacuum pump, compressor, container of compressed gas, or by way of a gas-generating chemical reaction.
Claims20
An apparatus, comprising:
- a carrier material selected from the group consisting of styrene-based polymers, styrene-based rubbers, EPDM, butadiene-based polymers, gum rubber, cellulosic rubber, thermoplastic polyether- or polyester-based polymers and rubbers (TPE), thermoplastic urethane (TPU), high surface area ceramic, activated Alumina, activated carbon, zeolites, molecular sieves, or an adsorbent material having high-surface area greater than about 10 m2/g, an absorbent cellulose or polymer sponge, a gas-generating chemical compound, and a mixture of two or more of the foregoing elements;
- and
- a volatile fluid dispersed inside the carrier material to a weight percent of between about 3% and about 400%, where weight percent is calculated as A/B*100, and A is weight of volatile fluid and B is weight of carrier material, to result in a spill-resistant solidified form of volatile fluid and to permit sustained release of volatile fluid vapor, wherein the volatile fluid is loaded into the carrier material at ambient temperature condition.
A method, comprising:
- disposing a quantity of volatile fluid in a substrate to form solidified volatile fluid;
- and
- coupling the solidified volatile fluid to a gas-moving system for discharge of volatile vapor through a discharge orifice to a local environment.
A method, comprising:
- providing a volatile fluid distribution system comprising:
- a volatile fluid chamber;
- a volatile fluid disposed inside the volatile fluid chamber, the volatile fluid being configured and arranged in a solidified form to permit sustained release of volatile fluid vapor to mix the vapor with a gas in the volatile fluid chamber;
- a gas discharge port to communicate a mix of volatile fluid vapor and gas from the volatile fluid chamber to permit discharge of volatile fluid in vapor form into the local atmosphere;
- and
- a gas-moving system to urge motion of gas from the volatile fluid chamber through the gas discharge port;
- and
- operating the volatile fluid distribution system to discharge volatile fluid vapor through the discharge port and into the local atmosphere.
