Abstract
Abstract This invention relates to a miracle air freshener and in particular to one having a can which has a dried compressed sponge, several pieces of fragrance, a soft wood and a figure. When we pour water into the can, the sponge will absorb water and expand several times of its compressed size and forces the figure strectched out of the can to beautify the place.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
An air freshener system comprising a can member having an internal volume and an internally directed recess trough volume and an internally directed recess trough member, a tab member, a cover member releasably secured to an upper end of said can member, said tab member secured to an upper surface of said cover member, a dried compressed sponge layer located adjacent a bottom portion of the can member, a resilient layer positionally located on the dried compressed sponge layer, a layer of fragrance composition located on the resilient layer, and an object having a stem member inserted within the resilient layer, whereby when liquid is poured into the can member, the dried sponge layer absorbs the liquid resulting in an expression in the volume of the sponge layer for displacing the object in an upward direction.
Claim 2
Dependent Claim
136 words
An air freshener system comprising a can member having an internal volume and an internally directed recess trough volume and an internally directed recess trough member, a tab member, a cover member releasably secured to an upper end of said can member, said tab member secured to an upper surface of said cover member, a dried compressed sponge layer located adjacent a bottom portion of the can member, a resilient layer positionally located on the dried compressed sponge layer, a layer of fragrance composition located on the resilient layer, and an object having a stem member inserted within the resilient layer, whereby when liquid is poured into the can member, the dried sponge layer absorbs the liquid resulting in an expression in the volume of the sponge layer for displacing the object in an upward direction.
Claim 3
Dependent Claim
24 words
The air freshener system as recited in claim 1, wherein the cover member is removable from the can member by lifting the tab member.
Claim 4
Dependent Claim
36 words
The air freshener system as recited in claim 1 or 2, wherein said internally directed recess trough member provides a blocking stop portion to prevent the liquid impregnated sponge layer from expanding external the can member.
Claim 5
Dependent Claim
17 words
The air freshener system as recited in claim 1, wherein said object may be of varying contour.
Claim 6
Dependent Claim
25 words
The air freshener system as recited in claim 1, wherein the resilient layer may be formed of a soft wood composition or plastic material composition.
Claim 7
Dependent Claim
29 words
The air freshener system as recited in claim 1 or 5, wherein said resilient layer has a plurality of holes formed therein for permitting fragrance odors to pass therethrough.
