Abstract

Abstract A container for an air treating agent such as an air freshener, deodorizer, or antibacterial agent, which may be easily placed in an air circulation system, as by attachment to an air filter customarily employed in such systems. The container includes a top and a bottom with the bottom having an upstanding peripheral wall. The top, bottom and peripheral wall are perforated to allow air flow therethrough and the bottom and the top are provided with outwardly extending portions which are adapted to embrace and sandwich opposite sides of an air filter to hold the container in place. Interengaging snap-fit connectors are provided on opposed elements to allow the same to be assembled on an air filter. Preferably the distance between the outwardly extending portions is no greater than, and preferably somewhat less, than the thickness of the air filter so that the container may be firmly mounted in place.

Claim 3
Dependent Claim 37 words
The combination of claim 1 further including a post within said cavity and secured to said containers for impaling a cake of an air treating agents and maintaining the same in a predetermined position within said cavity.
Claim 4
Dependent Claim 21 words
The combination of claim 1 wherein said releasable securing formation and said complementary releasable securing formation comprises interengaging snap fit connectors.
Claim 5
Dependent Claim 86 words
The combination of claim 3 further including a post within said cavity and secured to one part of said container for impaling a cake of an air treating agent and maintaining the same in a predetermined position within said cavity; one of said snap fit connectors being located on the end of said post opposite its point of securement to said one part of said container, the other of said snap fit connectors being located on another part of said container and aligned with said post.
Claim 6
Dependent Claim 158 words
An air treating device for use in treating air circulating in a forced air circulation system, comprising: an air filter including a layer of filtering material sandwiched between a pair of perforated backing members; an air-pervious container having an interior cavity adapted to receive an air treating agent and a selectively openable cover whereby access to said cavity may be achieved to initially place or subsequently replenish an air treating agent in said cavity; and means releasably securing said container to said air filter whereby said container may be removed from said air filter to replenish the air treating agent to be contained in said cavity and/or to permit said air filter to be disposed of without disposing of said container thereby permitting said container to be reused; said means releasably securing said container to said air filter includes at least one element engaging one of said perforated backing members; said element being on said selectively openable cover.
Claim 7
Dependent Claim 158 words
An air treating device for use in treating air circulating in a forced air circulation system, comprising: an air filter including a layer of filtering material sandwiched between a pair of perforated backing members; an air-pervious container having an interior cavity adapted to receive an air treating agent and a selectively openable cover whereby access to said cavity may be achieved to initially place or subsequently replenish an air treating agent in said cavity; and means releasably securing said container to said air filter whereby said container may be removed from said air filter to replenish the air treating agent to be contained in said cavity and/or to permit said air filter to be disposed of without disposing of said container thereby permitting said container to be reused; said means releasably securing said container to said air filter includes at least one element engaging one of said perforated backing members; said element being on said selectively openable cover.
