ABSTRACT:
A device for dispensing air-treating vapors having a frame, two relatively movable support members mounted in the frame, having facing, substantially parallel support surfaces and being relatively movable within the frame to adjust the spacing between the surfaces, and a flexible, generally flat dispensing pouch sandwiched between the support surfaces and having an inner storage container of flowable air-treating composition which is burstable by sandwiching pressure exerted through the support surfaces to release the composition for dispensing through apertures in the support members. The support surfaces squeeze and support the dispensing pouch to hold the released composition in contact with a good part of the inner surface of the dispensing pouch.
