ABSTRACT:
Disclosed herein is a dispenser comprising an inner member including a portion having an axis and a first end closed by a transverse wall, being resiliently displaceable in the direction of the axis between a collapsed condition and a normally extended condition, and defining an interior cavity adapted to contain a substance in the form of a vapor, an outer member movable relative to the inner member with respect to the axis and including a generally cylindrical portion in closely fitting telescopic relation to the inner member and having a first open end adjacent the transverse wall of the portion of the inner member, and a second end, and a wall closing the second end of the outer member cylindrical portion, and an aperture in at least one of the inner and outer members for affording air flow therethrough relative to the interior cavity in response to displacement of the inner member portion between the collapsed and extended conditions, whereby, the application of force in the direction of the axis causes relative axial movement in the direction affording displacement of the inner member portion to the collapsed condition with accompanying discharge of air with the substance in vapor form, and whereby release of the application of force causes axial movement of the outer member relative to the inner member in the direction affording re-extension of the inner member portion to the normally extended condition.
