First Claim
1. A vapor dispenser comprising a rectangular housing including interconnected top and bottom walls, opposed front and back walls, opposed first and second end walls, door means in said front wall for providing an access opening which can be opened and closed, a first partition extending in spaced relation to said top wall and between said end walls and between said front and back walls to define an air intake chamber between said first partition and said top wall, air inlet means communicating with said air inlet chamber, a second partition extending in spaced relation to said bottom wall and in generally parallel relation to said first partition and between said end walls and between said front and back walls to define an air outlet chamber between said second partition and said bottom wall and to define a central chamber between said first and second partitions, air outlet means communicating with said air outlet chamber, aperture means in said first and second partitions for affording air flow from said air inlet chamber to said central chamber and from said central chamber to said air outlet chamber, at least one tray member, means on said first and second end walls for horizontally supporting said tray member in said central chamber and for facilitating at least partial withdrawal of said tray member through said front wall access opening and means on said tray member for removably holding a plurality of relatively thin rectangular envelopes which contain a vaporizable substance to be dispensed as a vapor into the flow of air and which are arranged in parallel vertical relation to each other to permit air flow past said envelopes from said air inlet chamber to said air outlet chamber.

Abstract
A dispenser comprising a rectangular housing defining an air inlet chamber between the first partition and the top wall of the housing, a valved air inlet communicating with the air inlet chamber, a second partition defining an air outlet chamber between the second partition and the bottom wall of the housing and a central chamber between the first and second partitions, a valved air outlet communicating with the air outlet chamber, apertures in the first and second partitions for affording air flow from the air inlet chamber, at least one tray member, a support on the end walls for horizontally supporting the tray member in the central chamber and for facilitating at least partial withdrawal of the tray member, a holder on the tray member for removably holding a plurality of relatively thin rectangular envelopes which contain a substance to be dispensed and which are arranged in parallel vertical relation to each other to permit air flow past the envelopes from the air inlet chamber to the air outlet chamber, and a blower in one of the air inlet and air outlet chambers for inducing air flow from the air inlet chamber to the central chamber and from the central chamber to the air outlet chamber.
