CLAIMS

What is claimed is:

1. A capsule for a volatile material distribution system comprising:

a housing that extends along a longitudinal axis between a first end and a second end, the first end defining an inlet port and the second end defining an outlet port;

a volatile substance member that includes a volatile substance, the volatile substance member contained and supported within the housing;

a seal member disposed proximate the outlet port and configured to selectively move between an unsealed position and a sealed position relative to the outlet port, the outlet seal member substantially sealing the outlet port in the sealed position, the outlet port being unsealed with the outlet seal member in the unsealed position; and

the housing, with the outlet seal member in the unsealed position, configured to receive an airflow that flows into the inlet port, past the volatile substance member, and out of the outlet port.

2. The capsule of claim 1, wherein the outlet seal member is configured to passively move from the sealed position to the unsealed position due to pressure from the airflow into the capsule.

3. The capsule of claim 1, wherein the inlet port and the outlet port are substantially centered with respect to the longitudinal axis of the capsule.

4. The capsule of claim 3, wherein inlet port and the outlet port are substantially rounded and extend about the axis.

5. The capsule of claim 3, wherein the volatile substance member includes a substrate that defines at least one throughway for passage of the air through the volatile substance member; and

wherein the at least one throughway extends along the longitudinal axis.

6. The capsule of claim 1, further comprising an inlet seal member that is supported by the housing for movement between a sealed position and an unsealed position, the inlet seal member substantially sealing off the inlet port in the sealed position, and the inlet port being open with the inlet seal member in the unsealed position.

7. The capsule of claim 1, wherein the outlet port is defined between a first seal surface and a second seal surface of the housing, the first seal surface and the second seal surface spaced apart along the longitudinal axis;

wherein the outlet seal member is configured to move along the longitudinal axis between the sealed position and the unsealed position, the first seal surface limiting movement of the outlet seal member in a first direction along the longitudinal axis, the second surface limiting movement of the outlet seal member in a second direction along the longitudinal axis.

8. The capsule of claim 7, wherein the housing of the capsule includes a plurality of scallop-shaped apertures, the second seal surface defined between adjacent pairs of the plurality of scallop-shaped apertures.

9. A volatile substance distribution system comprising:

a base unit having a base unit housing that supports a fan and that defines an air outlet configured to direct air driven by the fan away from the base unit;

a capsule configured to be removably supported on the base unit, the capsule including:

a housing that extends along a longitudinal axis between a first end and a second end, the first end defining an inlet port and the second end defining an outlet port, the housing configured to move between an engaged position and a disengaged position relative to the base unit, the housing, in the engaged position, being removably supported on the base unit with the inlet port fluidly connected to the air outlet of the base unit, the housing, in the disengaged position, being spaced apart from the base unit;

a volatile substance member that includes a volatile substance, the volatile substance member contained and supported within the housing;

an outlet seal member disposed proximate the outlet port and configured to selectively move between an unsealed position and a sealed position relative to the outlet port, the outlet seal member substantially sealing the outlet port in the sealed position, the outlet port being unsealed with the outlet seal member in the unsealed position; and

the housing, in the engaged position and with the outlet seal member in the unsealed position, configured to receive the air from the air outlet that flows into the inlet port, past the volatile substance member, and out of the outlet port.

10. The system of claim 9, wherein base unit includes a receptacle that is recessed along the longitudinal axis;

wherein the air outlet is included in the receptacle and is centered with respect to the longitudinal axis;

wherein the inlet port and the outlet port are substantially centered with respect to a longitudinal axis of the capsule when the housing is in the engaged position; and

wherein the inlet port and the outlet port are separated at a distance along the longitudinal axis.

11. The system of claim 10, wherein the capsule is nested within the receptacle when engaged with the base unit.

12. The system of claim 10, wherein inlet port and the outlet port are substantially rounded and extend about the axis.

13. The system of claim 10, wherein the volatile substance member includes a substrate that defines at least one throughway for passage of the air through the volatile substance member; and

wherein the at least one throughway extends along the longitudinal axis.

14. The system of claim 9, further comprising an inlet seal member is supported by the housing of the capsule for movement between a sealed position and an unsealed position, the inlet port being substantially sealed when the inlet seal member is in the sealed position, the inlet port being open when the inlet seal member is in the unsealed position.

15. The system of claim 14, further comprising a controller that intermittently changes the fan between an ON state and an OFF state;

wherein, with the capsule engaged with the base unit, the inlet seal member remains supported in the unsealed position with the fan in both the ON state and the OFF state; and

wherein, with the capsule engaged with the base unit, the outlet seal member is supported in the sealed position with the fan in the OFF state;

wherein, with the capsule engaged with the base unit, the outlet seal is supported in the unsealed position with the fan in the ON state.

16. The system of claim 15, wherein the inlet seal member is biased toward the sealed position; and

wherein the outlet seal member is biased toward the sealed position.

17. The system of claim 16, wherein the inlet seal is configured to

mechanically move from the sealed position to the unsealed position as a result of engaging the capsule on the base unit; and

wherein the outlet seal is configured to passively move from the sealed position to the unsealed position due to pressure from the air moved by the fan into the capsule.

18. The system of claim 9, wherein the outlet port is centered with respect to the longitudinal axis of the capsule and is defined between a first seal surface and a second seal surface, the first seal surface and the second seal surface spaced apart along the longitudinal axis;

wherein the outlet seal member is configured to move along the longitudinal axis between the sealed position and the unsealed position, the first seal surface limiting

movement of the outlet seal member in a first direction along the longitudinal axis, the second surface limiting movement of the outlet seal member in a second direction along the longitudinal axis.

19. A method of manufacturing a volatile substance distribution system comprising:

forming a housing of a capsule that extends along a longitudinal axis between a first end and a second end, the first end defining an inlet port and the second end defining an outlet port, the housing configured to move between an engaged position and a disengaged position relative to the base unit, the housing, in the engaged position, being removably supported on the base unit with the inlet port fluidly connected to the air outlet of the base unit, the housing, in the disengaged position, being spaced apart from the base unit;

providing a volatile substance member that includes a volatile substance within the housing;

supporting an outlet seal member proximate the outlet port and configured to selectively move between an unsealed position and a sealed position relative to the outlet port, the outlet seal member substantially sealing the outlet port in the sealed position, the outlet port being unsealed with the outlet seal member in the unsealed position;

the housing, in the engaged position and with the outlet seal member in the unsealed position, configured to receive the air from the air outlet that flows into the inlet port, past the volatile substance member, and out of the outlet port.

20. The method of claim 19, further comprising forming the base unit to include the projection.
