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 in turn 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 die cuts, provided in the walls 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 die cuts in a nonaligned position thereby resealing the container. A portion of the inner member which projects above the upper edge of the outer sleeve member may be readily grasped to facilitate the relative rotation of the tubular members.
