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.

An integrally formed multi-component structure comprising a plurality of fluid transmissive 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, wherein the three dimensional bonded fiber fluid transmissive component has a predetermined cross-sectional shape that is substantially constant along at least one axis of the multi-component structure and wherein each fluid transmissive component has an interface with at least one other fluid transmissive component.
An integrally formed multi-component structure comprising a plurality of three-dimensional bonded fiber fluid transmissive components, each comprising a plurality of polymeric fibers bonded to each other at spaced apart contact points, the fibers collectively defining tortuous fluid flow paths, wherein a first three-dimensional bonded fiber fluid transmissive component has a first predetermined cross-sectional shape that is substantially constant along at least one axis of the multi-component structure and a first set of fluid flow characteristics and a second three-dimensional bonded fiber fluid transmissive component has a second predetermined cross-sectional shape that is substantially constant along at least one axis of the multi-component structure and a second set of fluid flow characteristics that is different from the first set of fluid flow characteristics, and wherein the first three-dimensional bonded fiber fluid transmissive component has an interface with the second three-dimensional bonded fiber fluid transmissive component.
A method of forming an ink jet printer cartridge, the method comprising:
- providing an exterior case defining a reservoir cavity;
- providing an integrally formed multi-component structure comprising a plurality of fluid transmissive 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, the three dimensional bonded fiber fluid transmissive component having a predetermined cross-sectional shape that is substantially constant along at least one axis of the multi-component structure, and each fluid transmissive component having an interface with at least one other fluid transmissive component;
- and
- disposing the multi-component structure within the reservoir cavity to form the ink jet printer cartridge.
A method of forming an air freshener, the method comprising:
- providing an exterior case defining a reservoir cavity;
- providing a wick comprising a multi-component structure comprising a plurality of fluid transmissive 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, the three dimensional bonded fiber fluid transmissive component having a predetermined cross-sectional shape that is substantially constant along at least one axis of the multi-component structure, and each fluid transmissive component having an interface with at least one other fluid transmissive component, the wick having first and second wick ends;
- and
- disposing at least a portion of the wick within the reservoir cavity so that the first wick end would be in fluid communication with liquid introduced into the reservoir cavity.
