Abstract
A scent sampler and air freshener has a wafer of an absorbent resilient material infused with a liquid containing a scent. The wafer is encapsulated in a chamber formed between two panels of sheet material with edges sealed together to form an envelope. An opening in one of the panels enables scent from the liquid to be emitted to the ambient atmosphere. The rate of emission can be increased by squeezing the panels to compress the wafer. The interior surfaces of the panels can be coated with a barrier film to prevent leakage of the liquid from contaminating the sheet material.
