A method of dispensing a fluid comprising generating a gas from a liquid, directing the gas to an expandable gas chamber to expand a volume of the expandable gas chamber, reducing a volume of a fluid chamber in response to expansion of the expandable gas chamber to dispense an amount of the fluid from the fluid chamber, and removing the gas from the expandable gas chamber to collapse the expandable gas chamber.

Gas generation dispenser method for on-demand fluid delivery

An apparatus for delivering a beneficial agent is disclosed in one embodiment of the invention as including a water collection chamber. A water-transporting membrane is provided to communicate with the water collection chamber. An extraction chamber receives water through the water-transporting membrane, expanding the extraction chamber. A dispensing chamber, containing a beneficial agent, is configured to contract upon expanding the extraction chamber. This causes the dispensing chamber to expel the beneficial agent through a subterranean delivery channel, such as a rigid hollow spike. In certain embodiments, a rate adjustment mechanism may control the rate that water is received through the water-transporting membrane, thereby controlling the rate the beneficial agent is expelled. The water-transporting membrane has features that repel osmagent from passing through to the water collection chamber. The apparatus features steady rate performance without refreshing the water chamber and low temperature sensitivity.

An apparatus for delivering a beneficial agent to a subterranean location is disclosed in one embodiment of the invention as including a water collection chamber having a substantially open end. A water-transporting membrane is provided to communicate with the water collection chamber. An extraction chamber receives water through the water-transporting membrane, expanding the extraction chamber. A dispensing chamber, containing a beneficial agent such as fertilizer, is configured to contract upon expanding the extraction chamber. This causes the dispensing chamber to expel the beneficial agent through a subterranean delivery channel, such as a rigid hollow spike. In certain embodiments, a rate adjustment mechanism may control the rate that water is received through the water-transporting membrane, thereby controlling the rate the beneficial agent is expelled from the subterranean delivery channel.

Apparatus and method for delivering beneficial agents to subterranean locations

A device for controllably releasing a fluid into an ambient environment. According to a particular embodiment of the present invention, the device comprises a housing having a fluid compartment and an orifice compartment disposed adjacent thereto and in fluid communication therewith via an orifice. The fluid compartment contains the fluid for release to the ambient environment. The orifice compartment includes a fluid exit opening covered by a removable sealing element and contains an initial quantity of fluid when the device is in an inactivated state. A fluid restrictor is disposed adjacent the orifice to restrict fluid flow from the fluid compartment into the orifice compartment in the inactivated state. A gas-generating cell is in selective communication with the fluid compartment such that gas generated by the cell is directed into the fluid compartment when the device is in an activated state. A fluid membrane is disposed between the gas-generating cell and the fluid compartment that allows the gas generated by the cell to pass therethrough to the fluid compartment in the activated state while preventing fluid within the fluid container from passing therethrough to the cell in the inactivated state. The device is activated by removing the sealing element to allow the initial quantity of fluid to exit out of the orifice compartment via the fluid exit opening and activating the cell to generate gas and force fluid from the fluid compartment to the orifice compartment and out the fluid exit opening in a controlled manner.

Automatic cyclic fluid delivery device and associated process

A fluid delivery apparatus includes a housing having an open end and an interior surface. The interior of the housing defines a cavity within the housing. The cavity, in combination with a piston-like member, defines a reservoir for containing a fluid (e.g. such as an aromatic or other solvent or a solvent in which has been dissolved an aromatic substance). The piston has a port, and fits in piston-like arrangement within a cylinder contained within the housing. The piston moves within the housing, and movement of the piston acts to displace fluid from the port upon contraction of the reservoir (e.g. when the annular piston is driven into the device). Preferably, a fluid tight membrane covers the housing's open end. The apparatus also preferably further includes a conduit to transport fluid from the housing of the reservoir. The conduit has, on a first end, an exterior circumference sized and shaped to interact with the port of the annular member. On the second end of the conduit is preferably associated a sponge, wick or equivalent fragrance dispenser.
