Abstract: A carton for releasing an active material, such as an air freshener, to the atmosphere includes an outer imperforate sleeve slidably receiving in nesting relation an inner sleeve housing an air freshener cake. The inner sleeve has a plurality of openings for exposing the cake of air freshener material to the atmosphere as the openings are selectively exposed by sliding the inner sleeve relative to the outer sleeve. The inner sleeve is slidable between a first position defined by abutment with the scaled closure of the outer sleeve and a second position intermediate the end containing the sealed closure of the outer sleeve and the opposite end thereof so as to selectively expose certain ones of the openings in the inner sleeve. The inner sleeve contains a sealed closure having a panel extending outwardly beyond the side panels thereof for contact with a pair of locking tabs on the bottom edge of the outer sleeve to preclude disassembly of the first and second sleeves.

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 disk shaped air freshener includes opposed mating trays which define a cavity therebetween and which are engaged for rotation relative to each other. Windows are defined in both of the trays, and openings to the cavity are increased, decreased, or shut entirely by relative rotation of the trays to alter the alignment of the windows. One tray has an axial sleeve and the other has several cantilevered arms which fit through the sleeve and which engage a radial groove in the sleeve to the hold the trays together in relatively rotatable fashion. A scented element is confined within the cavity between the trays and is allowed to provide a freshening scent through openings defined by the aligned windows in the tray. An adhesive pad is centrally located on one of the trays at the axial center of the air freshener.

The vaporizer is preferably made of a plastic or other flexible material and may be carried out in various specific embodiments wherein the active substances, which may be toxic, are kept safely out of contact with humans and can be made available for their intended use in controlled and variable amounts. The active substances may be in a spherical or lenticular casing or housing and can be released from outside in a manner to be volatilized for insecticidal or other activity. There is a holder provided for absorption of the volatiles emerging from the casing after the latter is opened by a member actuable externally thereof for cutting the same.

Abstract: A liquid dispenser for a flush tank includes a dispensing closure in engagement with an open top container for axial movement relative thereto, the closure having discharge ports therein defining flow passages between the interior and exterior of the container and capable of being opened and closed during such axial movement. The closure includes a hollow cap having air vents therein, and a sleeve extending inwardly of the container so that liquid may flow during a tank refill operation through the ports and beneath the sleeve for thoroughly mixing with concentrated soluble material within the container before flowing into the cap while forcing the air through the vents. And, during a tank flushing operation, the mixed liquid is dispensed through the ports after it again mixes with the soluble material below the sleeve, the mixed liquid in the cap then being replaced by air through the vents during the discharge operation.

Abstract: A dispenser for vapors characterized by an upstanding enclosure made of folded flexible sheet stock and having two upstanding opposed primary dispensing walls, one or more structural members within the enclosure to provide reinforcing dimensional stability between the primary walls and releasably holding a vaporizable composition, and air flow channels from one dispensing wall to the other. Preferred embodiments relate to variations in the structural member(s), the specific materials used, a barrier used to prevent loss of vaporizable composition by wicking and an impermeable film tightly wrapped therearound. The invention can be used for dispensing air fresheners, insecticides, and other air-treating vapors.

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.
