System for distributing volatile substance with base unit and self-sealing removable capsule

A volatile substance distribution system comprising:

• a base unit having a base unit housing that supports a fan and that defines an air opening for an airflow of air driven by the fan, the base unit including a projection that projects from the base unit housing;
• and
• a capsule configured to be removably supported on the base unit, the capsule including:
• a housing with a port, the port at least partly defined by a seal surface, 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 port fluidly connected to the air opening 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 within the housing;
• and
• a seal member that is supported by the housing for movement between a sealed position and an unsealed position, at least part of the seal member sealing against the seal surface to close the port when in the sealed position, the at least part of the seal member spaced at a distance from the seal surface to open the port when in the unsealed position;
• the seal member, when the capsule is disengaged from the base unit, being in the sealed position;
• and
• the projection of the base unit, when the capsule is engaged with the base unit, being received in the capsule to support the seal member in the unsealed position such that air moved by the fan flows through the port.

A method of manufacturing a volatile substance distribution system comprising:

• forming a housing of a capsule to have a port, the port at least partly defined by a seal surface, the housing configured to move between an engaged position and a disengaged position relative to a base unit, the housing, in the engaged position, being removably supported on the base unit with the port fluidly connected to the air opening 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;
• and
• supporting a seal member by the housing for movement between a sealed position and an unsealed position, at least part of the seal member sealing against the seal surface to close the port when in the sealed position, the at least part of the seal member spaced at a distance from the seal surface to open the port when in the unsealed position;
• the seal member, when the capsule is disengaged from the base unit, being in the sealed position;
• and
• the seal member, when the capsule is engaged with the base unit, configured to be supported in the unsealed position by a projection of the base unit that is received in the capsule such that air moved by a fan flows through the port.
