Abstract
Abstract A deodorizing device for use in a pet's litter box, for example. The deodorizing device has a container body having an open end, a closed end and a cylindrical side wall defining a cavity therein. Chunks of zeolite are disposed within the cavity and retained within the container body by a sealing mechanism. The cylindrical side wall of the container body has a plurality of substantially uniform-sized apertures disposed thereon to permit exposure of the retained zeolite to the odors. A sealing mechanism may be permanently or releasably attached to the container body. A securing mechanism secures the deodorizing device to a structure within the malodorous environment. The zeolite after use can be recharged by exposing to fresh air, sunlight and heat and then reused. In addition to being used in a pet's litter box, the device can be used in many environments, including animal containment areas, living areas, production areas, food storage areas, work areas and automobiles.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
209 words
A deodorizing device for deodorizing a malodorous environment comprising: a container formed by an elongated hollow body having a generally cylindrical exterior wall terminating in open ends; a plurality of through-openings penetrating said cylindrical wall and being spacedly disposed about the full circumference thereof to establish communication between the interior of said container and the environment exteriorly thereof; said container interior containing an amount of particulate zeolite, the particle sizes of which are greater than the size of said through-openings to permit retention of said zeolite within said container; end caps closing the respective ends of said container, at least one of said end caps being defined by a body having a generally cylindrical external surface and a concentric recess extending into said body from one end thereof, said recess being formed of a diameter to tightly engage the exterior wall of said container for closing at least one said end thereof; said external surface of said end caps being concentrically spaced from said exterior wall of said container by an amount sufficient to permit exposure of said container exterior wall about its entire circumference to said environment; and means on at least one of said end caps for mounting and supporting said deodorizing device in its operative position.
Claim 2
Dependent Claim

A deodorizing device for deodorizing a malodorous environment comprising: a container formed by an elongated hollow body having a generally cylindrical exterior wall terminating in open ends; a plurality of through-openings penetrating said cylindrical wall and being spacedly disposed about the full circumference thereof to establish communication between the interior of said container and the environment exteriorly thereof; said container interior containing an amount of particulate zeolite, the particle sizes of which are greater than the size of said through-openings to permit retention of said zeolite within said container; end caps closing the respective ends of said container, at least one of said end caps being defined by a body having a generally cylindrical external surface and a concentric recess extending into said body from one end thereof, said recess being formed of a diameter to tightly engage the exterior wall of said container for closing at least one said end thereof; said external surface of said end caps being concentrically spaced from said exterior wall of said container by an amount sufficient to permit exposure of said container exterior wall about its entire circumference to said environment; and means on at least one of said end caps for mounting and supporting said deodorizing device in its operative position.
Claim 3
Dependent Claim
28 words
A deodorizing device according to claim 1 in which said mounting means comprises means on said external surface of said end caps for joinder to an adjacent surface.
Claim 4
Dependent Claim
46 words
A deodorizing device according to claim 1 in which said at least one of said end caps is formed of a body whose diameter is sufficiently large with regard to the length of said container body as to support said device in a free standing disposition.
