Abstract:
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; and said coefficient of static friction having a value of greater than 0.4 at said contact interface.
