ABSTRACT:
A fragrance emitting unit which when hand actuated expels into the atmosphere a pulse of fragrance. Included in the unit is an air-filled container provided with a small jet opening, the container having a flexible wall which when depressed subjects the air in the container to pressure to cause a pulse of air to be expelled through the opening. Interposed between the jet opening and the interior of the container is an air-permeable, porous member impregnated with liquid fragrance whereby when the unit is first actuated, a pulse of air is forced through the member to extract fragrance therefrom to produce a fragrance mist that is discharged through the opening. When the wall is then released and seeks to resume its normal state, the resultant vacuum created within the container causes air to be drawn into the jet opening and to be forced through the member into the interior so that the charge of air in the container is now laden with fragrance. As a consequence, when the unit is again actuated, the mist expelled therefrom carries a high concentration of fragrance.
