Abstract: Air cleaner assemblies, components therefor, and features thereof are described. Also described are methods of assembly and use. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. Methods of assembly and use are described.

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.

Abstract: A cylinder type display box is made from a single sheet of paperboard material and includes a base and two upstanding sidewalls. The display box further includes a tubular plastic sleeve member disposed over the base and sidewalls so as to form a plastic front wall, top wall, and back wall. The base and sidewalls of the box are generally prismatic in configuration, each having spaced apart panel members. The base includes a pair of substantially parallel locking slits extending from the front wall to the back wall, each of the locking slits being adjacent to one of the sidewalls. Each locking slit includes an elongated central portion and a pair of end portions, the end portions of each slit being flared toward its adjacent sidewall. Each of the sidewalls has a locking portion receivable in the locking slit adjacent thereto. Each locking portion includes a central portion integral with the respective sidewall and a pair of end tabs.
