ABSTRACT:
A two part paperboard container having adjustable vents is described and is intended for use with a sublimable composition. The container consists of an inner tubular member and an outer tubular sleeve member, both of a truncated, conical configuration. The inner tubular member, which is adapted to receive the sublimable composition, is disposed within the outer sleeve member. The outer surface of the inner member is in frictional engagement with the inner surface of the outer sleeve member which functions to seal the carton. The inner member may be rotated relative to the outer sleeve member to at least partially align apertures provided in the upper cover portions of the tubular members, thereby exposing the composition to the air enabling it to sublime. Continued relative rotation of the tubular members will reset the apertures in the upper cover portions in a nonaligned position, thereby resealing the container. A handle means connected to a lower cover portion of the inner tubular member is provided to facilitate the relative rotation of the tubular members.
