ABSTRACT:
Disclosed are a carton having adjustable air passages and a blank for forming it. The carton is formed of slidable inner and outer tapered sleeves having complementary spaced openings. The openings are positioned to provide open air passages when the inner sleeve is slid to a first position, and to close the passages as the inner sleeve is moved toward a second position. This carton is especially adapted to hold an air freshening medium during storage and to permit controlled exposure of it to the air during use.
