  • Patent number: 8334034
    Abstract: A fluid reservoir for retaining a particular fluid against an environmental force is disclosed. The fluid reservoir includes a three dimensional porous body that has a plurality of reservoir capillaries formed therein and has a transport volume and effective capillarity in the force direction for the particular fluid when the porous body is oriented in a predetermined orientation. The fluid reservoir also includes at least one lateral indentation in a surface of the porous body. Each of the at least one lateral indentation defines opposing reservoir surfaces each having a lateral surface component orthogonal to the force direction. The at least one lateral indentation is configured so that at least a majority of the reservoir capillaries have a force-aligned length component that is less than the effective capillarity for the particular fluid.

  • Patent number: 8047453
    Abstract: Aspects of the invention include an air freshener device that emits fragrance through the evaporation of a fragrance-containing fluid comprising: a container, comprising a particular volume of the fragrance-containing fluid; a wick disposed partially in, and partially out of the fragrance-containing fluid, the wick having an immersion section immersed in the fluid so as to displace a displacement volume of fluid and a non-immersion section extending outward from a surface of the fluid, the immersion and non-immersion section being disposed on opposite lateral ends of the wick; the wick further comprising a displacement portion and a wicking portion, the displacement portion being configured to displace a desired first volume of fluid, the wicking portion being configured to wick a second volume of fluid; the displacement portion and the wicking portion designed to achieve a desired ratio between the displaced first volume of fluid and the wicked second volume of fluid.

  • Patent number: 7888275
    Abstract: An integrally formed multi-component structure is disclosed, the multi-component structure comprising a plurality of components, at least one of which is a three-dimensional bonded fiber fluid transmissive component comprised of a plurality of polymeric fibers bonded to each other at spaced apart contact points, the fibers collectively defining tortuous fluid flow paths, and wherein each component has an interface with at least one other component.
