| 1. A dispensing system for a volatile liquid, comprising:
a fan adapted to push an air stream;
a capillary member that is in fluid communication with a reservoir for the volatile liquid, the capillary member having a
body, in which a portion of the body is positioned within the air stream with the fan activated; in which the portion of the
body is impervious to passage of the air stream therethrough in a direction of the air stream and in which the air stream
passes unobstructed over opposing surfaces of the capillary member aligned generally transverse to the direction of the air
stream; and
a guide associated with the fan and defining opening, having a predetermined dimension, to selectively receive the capillary
member and to position the portion of the body such that the portion of the body is in the air stream when the fan is activated;
wherein a blade of the fan has a dimension R extending from an axis of rotation of the fan blade to an edge of the fan blade
farthest from the axis of rotation; and
the portion of the body of the capillary member in which the body of the capillary member has a width W which does not exceed
1.2 R.
