Air freshener
An air freshener has two hemispherical shells joined by a ring that includes a number of openings into the interior of the air freshener. A lip of the ring protrudes into the interior region and holds a scent element in place within the air freshener.
1 . An air freshener comprising:
a first shell with a circular opening;
a second shell with a circular opening;
a ring joining the circular openings of the shells to define an interior region within the shells, and having:
(a) a lip protruding into the interior region around at least a portion of the circular opening; and
(b) at least one opening into the interior region; and
a scent element held in place within the interior region by the lip of the ring.
2 . The air freshener of claim 1 wherein at least one of the shells is generally hemispherical.
3 . The air freshener of claim 1 wherein the scent element abuts the interior surface of one of the shells.
4 . The air freshener of claim 1 wherein the joined shells and ring have a generally spherical shape.
5 . The air freshener of claim 1 wherein the openings in the ring are closable.
6 . The air freshener of claim 1 wherein the scent element comprises a pad.
7 . The air freshener of claim 1 wherein the scent element comprises a disk having circular peripheral rim abutting the lip of the ring, and a surface abutting the interior surface of one of the shells.
8 . An air freshener comprising:
a first shell with an interior surface and a circular opening;
a second shell with a circular opening;
a ring joining the circular openings of the shells to define an interior region within the shells, and having a lip protruding into the interior region around at least a portion of the circular opening;
at least one opening into the interior region; and
a generally circular scent element engaging the lip of the ring about its periphery and abutting the interior surface of the first shell.
9 . The air freshener of claim 8 wherein at least one of the shells is generally hemispherical.
10 . The air freshener of claim 8 wherein the joined shells and ring have a generally spherical shape.
11 . The air freshener of claim 8 wherein the openings into the interior region pass through the ring.
12 . The air freshener of claim 8 wherein the openings into the interior region are closable.
13 . The air freshener of claim 8 wherein the scent element comprises a pad.
14 . An air freshener comprising:
a first hemispherical shell with a hemispherical interior surface and a circular opening;
a second hemispherical shell with a hemispherical interior surface and a circular opening;
a ring joining the circular openings of the shells to define an interior region within the shells, and having:
(a) a lip protruding into the interior region around at least a portion of the circular opening; and
(b) at least one opening into the interior region;
a first generally-circular scent element engaging the lip of the ring about its periphery and abutting the interior surface of the first shell; and
a second generally-circular scent element engaging the lip of the ring about its periphery and abutting the interior surface of the second shell;
wherein the interior region between scent elements allows diffusion of scent from the scent elements through the openings in the ring.
15 . The air freshener of claim 14 wherein the openings in the ring are closable.
16 . The air freshener of claim 14 wherein the scent elements comprise pads.
