Abstract
A re-usable aroma releasant is provided on a package of tobacco product such as cigarettes, pipe tobacco, fine cut tobacco and the like. The aroma releasant is activated to release aroma every time the package is opened. The packages comprises a tobacco product containment portion and a tobacco product containment closure portion. The closure portion is removed from the containment portion to gain access to the tobacco product. The aroma releasant may have a peel seal connecting the containment portion and the closure portion. The peel seal seals the aroma in the substrate reservoir provided on the package. The peel seal is peeled from the substrate reservoir to permit opening of the package and simultaneously releasing aroma from the reservoir. The peel seal reseals the reservoir on closure of the package. A re-usable aroma releasant is provided where every time the smoker opens the package, fresh aroma is released. Suitable aromas include, essence of tobacco, coffee, menthol or other pleasant aromas associated with tobacco smoking.
