Advanced scent dispersion device
A scent delivery system includes a housing that releases a volatile substance from a porous body into the air. The housing may be part of a scent dispersion device that includes volatilization as directed by a fan and a controller within the housing.
1. A method for making a scented refill cartridge, the method comprising:
providing a wick with a central axial opening therethrough, the wick having an absorbent scent-retaining material;
placing the wick within a recess on a platform;
pouring liquid fragrance into the central opening to a level that is below a top surface of the wick to allow the liquid to be absorbed into the absorbent material;
placing the wick within a cup support, the cup having an interior, a top opening, and a bottom opening;
sealing one or more of the top opening and bottom opening with a covering to seal the wick within the interior of the cup.
2. The method of claim 1 , wherein the covering includes a removable foil or film.
3. The method of claim 1 , further comprising an act of moving the platform so that the central axial opening of the wick is directly underneath an outlet that communicates liquid fragrance.
4. The method of claim 1 , wherein the liquid fragrance is at room temperature.
5. The method of claim 1 , wherein the liquid fragrance is metered.
6. The method of claim 1 , further comprising between the pouring step and the placing step, further comprising steps of waiting for a period of time.
7. The method of claim 1 , wherein the cup includes an inner ridge for supporting the wick within the interior of the cup.
8. The method of claim 1 , wherein the recess is dimensioned such that it provides a friction fit with the wick.
9. The method of claim 1 , wherein the recess includes a circular cross-section and a depth that is less than half to half the height of the wick.
10. The method of claim 3 , wherein placing the wick within the cup further includes an act of aligning the wick on the inner ridge so that the inner ridge only partially covers a bottom surface of the wick and the bottom surface of the wick is at least partially exposed through the bottom opening of the cup, providing air pathways to communicate with the bottom surface of the wick.
11. The method of claim 1 , wherein placing the wick within the cup further includes an act of centering the cylinder between inner walls of the cup and thus defining air pathways between the inner walls of the cup and outer walls of the cylinder for air to flow from the bottom opening of the cup to the top opening of the cup.
12. The method of claim 1 , wherein pouring occurs at a pouring station and the method further comprises steps of:
moving the platform along a horizontal plane to move the wick from the pouring station and to move a second wick to the pouring station so that a second wick on the platform may receive liquid fragrance, and
pouring liquid fragrance into a central opening of the second wick.
13. The method of claim 1 , wherein placing the wick within the cup further includes an act of positioning the wick so that the wick may form a concentric configuration with a fan to communicate air through the cup.
14. The method of claim 1 , wherein the wick, when placed within the cup, rests below the top opening of the cup and above the bottom opening of the cup.
15. An apparatus for making a scent-absorbed wick comprising:
a first movable horizontal surface,
multiple recesses in the first movable surface, each recess for holding an absorbent structure with at least one hole or opening,
a pouring station, including structure for pouring liquid fragrance into the at least one hole or opening when a recess with an absorbent structure is at the pouring station,
structure for moving the recess to move successive recesses in turn into and out of the pouring station.
16. The apparatus of claim 15 , further comprising:
a second movable horizontal surface, multiple rows of holders in the second movable surface, each holder for holding the absorbent structure in a cup support stamping station, including first structures for applying pressure to seal top edges of the cup support and second structures for applying pressure to seal bottom edges of the cup support,
structure for moving the multiple rows of holders to move successive rows of holders into and out of the first structures, second structures, and stamping station.
17. The apparatus of claim 15 , wherein the first movable horizontal surface includes a belt, or a rotating disc, that is configured to transport scent-absorbed solid wicks into and out of the pouring station.
18. The apparatus of claim 16 , wherein the second movable horizontal surface includes a belt, or rotating disc, that is configured to transport rows of holders of cup supports with scent-absorbed wicks into and out of the first structures, second structures, and stamping station.
19. The apparatus of claim 16 , wherein the pressure for sealing the bottom edges and the top edges includes a first hydraulic actuator that actuates a facing to press against the bottom edges of the cup support and a second hydraulic actuator that actuates a facing to press against the top edges of the cup support.
20. The apparatus of claim 15 , further comprising:
a third horizontal surface that is configured to transport a cup support with wick and one or more coverings, the surface including multiple holders,
a labeling station, including structure for applying at least one label on the cup support or covering,
structure for moving each cup support to move successive cup supports in turn into and out of the labeling station.
