Abstract
A volatile substance delivery system includes a volatile substance container to contain a volatile substance, an optional absorbent and collapsible element disposed within the container to reduce presence of undesired air during manufacture of the device, an outlet to deliver a volume of the volatile substance from the volatile substance container to an ambient environment, and a manual screw pump to reduce volume (or sometimes, just increase pressure) within the volatile substance container and promote the delivery of the volatile substance from the volatile substance container.
Claims20
A no-drip volatile substance delivery system comprising:
- a volatile substance container to contain a volatile substance;
- an absorbent element disposed inside the volatile substance container, the absorbent element being sized in agreement with an initial total volume of the volatile substance container and structured to absorb the volatile substance and consequently displace substantially all air from the initial total volume of the container to resist a gas-expansion caused change in pressure or volume inside the volatile substance container responsive to an increase in temperature, the absorbent element being collapsible to permit displacement of the volatile substance from confinement in the absorbent element;
- an outlet to deliver a volume of the volatile substance from the volatile substance container to an ambient environment;
- and
- a manual screw pump to increase pressure within the volatile substance container and promote the delivery of the volatile substance from the volatile substance container, wherein:
- the volatile substance delivery system is structured such that a successively-reduced volume is defined in the volatile fluid chamber subsequent to each discharge of volatile fluid and the collapsible element is continuously reduced in volume.
A method for manufacturing a no-drip volatile substance delivery system, the method comprising:
- providing a volatile fluid delivery device comprising a volatile fluid chamber to hold a volatile fluid and a manual screw pump operable to displace volatile fluid from the volatile fluid chamber;
- disposing a collapsible and absorbent element within the volatile substance container, wherein the absorbent element is structured such that an initial total volume of the volatile substance container is substantially occupied by the absorbent element when saturated by a volatile substance to displace undesired air in the volatile substance container, the absorbent element being collapsible under operation of the screw pump to discharge volatile fluid from the volatile fluid chamber, the volatile fluid delivery device being structured to maintain a successively-reduced volume in the volatile fluid chamber subsequent to each discharge of volatile fluid;
- and
- charging the volatile fluid chamber with a quantity of volatile fluid effective to displace substantially all air in the collapsible element and consequently in the volatile fluid chamber.
A method for operating a no-drip volatile substance delivery system, the method comprising:
- twisting a manual screw pump;
- collapsing an absorbent element disposed within a volatile substance container in response to twisting the manual screw pump, wherein an initial total volume of the volatile substance container is occupied by the absorbent element saturated by a volatile substance to displace undesired air in the volatile substance container;
- and
- delivering a volume of the volatile substance from an outlet of the volatile substance container to an ambient environment in response to collapsing the absorbent element within the volatile substance container.
