An apparatus and method are disclosed and pertain to a lid for use with a container having a rim and an opening where volatile esters from an aromatic compound are dispersing into the environment and for enhancing the identification of the volatile esters. The lid is comprised of a generally planar laterally stabilized gas restrictive material for decreasing the dispersion rate of the volatile esters, resulting in increased concentration of the volatile esters within the container and enhancing the identification of the volatile esters emitted from the aromatic compound. The lid includes a surface for coupling to the rim in a manner that laterally stabilizes the lid so that it remains sufficiently fixed to the rim during agitation of the container. The surface also permits the lid to be removed from the rim.

1. An apparatus for use with a container having a rim and an opening where volatile esters from an aromatic compound are dispersing into the environment and for enhancing the identification of said volatile esters, the apparatus comprising: a laterally-stabilized planar gas restrictive lid for decreasing the dispersion rate of the volatile esters, resulting in increased concentration of the volatile esters within the container and enhancing the identification of the volatile esters, said lid having a surface for coupling to the rim, said surface disposed to have a continuously flat surface;said lid further including a bottom surface that includes said surface for coupling to the rim, said bottom surface disposed to have a continuously flat surface across the entire width of said lid so that said surface for coupling to the rim does not contact the sides of the rim;said lid disposed with a coefficient of static friction at a contact interface between said surface and the rim, said coefficient of static friction providing lateral stabilization that enables said lid to remain coupled to the rim without slipping when the aromatic compound is agitated; andsaid coefficient of static friction having a value of greater than 0.4 at said contact interface. 2. The apparatus of claim 1, wherein said lid is solid and obstructs passage of volatile esters. 3. The apparatus of claim 1, wherein said lid is configured to have an approximately circular shape with a diameter between 40 and 120 mm. 4. The apparatus of claim 1, wherein said lid is comprised of vinyl sheeting having a thickness of 4 to 60 mils achieving lateral stability by virtue of the coefficient of static friction at the contact interface between said surface and said rim. 5. The apparatus of claim 1, wherein said lid is comprised of material that includes plastic. 6. The apparatus of claim 1, wherein said lid is clear and contains markings to improve the visibility and usability of said lid.
