Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
185 words
A device for simultaneously cleaning teeth and massaging gums, comprising: a spool-shaped member formed as a single piece of resilient, non-toxic material, said member comprising: a central body portion including a central void, said central body portion having a substantially circular outer circumference to facilitate rolling said central body portion between the teeth from tooth to tooth; and first and second substantially circular dish-shaped flange portions extending radially outward from opposite ends of said central body portion, said first flange portion having a concave surface facing said central body portion to generally conform to the labial surfaces of a user's teeth, said second flange portion having a convex surface facing said central body portion to generally conform to the lingual surfaces of a user's teeth; said central void of said body portion facilitating collapse of said central body portion which induces a closure of said flanges against the teeth and gums of a user so that said inner surfaces of said flanges contact the surfaces of the teeth and gums to thereby clean the surfaces of the teeth and gums by rubbing on said surfaces.
Claim 2
Independent Claim
185 words
A device for simultaneously cleaning teeth and massaging gums, comprising: a spool-shaped member formed as a single piece of resilient, non-toxic material, said member comprising: a central body portion including a central void, said central body portion having a substantially circular outer circumference to facilitate rolling said central body portion between the teeth from tooth to tooth; and first and second substantially circular dish-shaped flange portions extending radially outward from opposite ends of said central body portion, said first flange portion having a concave surface facing said central body portion to generally conform to the labial surfaces of a user's teeth, said second flange portion having a convex surface facing said central body portion to generally conform to the lingual surfaces of a user's teeth; said central void of said body portion facilitating collapse of said central body portion which induces a closure of said flanges against the teeth and gums of a user so that said inner surfaces of said flanges contact the surfaces of the teeth and gums to thereby clean the surfaces of the teeth and gums by rubbing on said surfaces.
Claim 3
Dependent Claim
49 words
The device as defined in claim 1, wherein at least one of the surfaces of the first and second flange portions facing the central body portion has a plurality of circumferentially spaced projections, said projections positioned to contact the surfaces of the teeth and the areas between the teeth.
Claim 4
Dependent Claim
37 words
The device as defined in claim 2, wherein the projections are thorn-shaped, said thorn-shaped projections shaped and positioned to dislodge food material from the areas between the teeth and pull the material away from the gum line.
Claim 5
Dependent Claim
12 words
The device as defined in claim 2, wherein the projections are bristles.
Claim 6
Dependent Claim
12 words
The device as defined in claim 2, wherein the projections are wipers.
Claim 7
Dependent Claim
54 words
The device as defined in claim 1, wherein at least one of the inner surfaces of the first and second flange portions has a plurality of circumferentially spaced cavities, the edges of said cavities contacting the surfaces of the teeth upon closure of the flanges to thereby provide a scraping action on the teeth.
Claim 8
Dependent Claim
22 words
The device as defined in claim 6, wherein the cavities penetrate through at least one of the first and second flange portions.
Claim 9
Dependent Claim
31 words
The device as defined in claim 6, wherein the cavities are indentations in at least one of the surfaces of the first and second flange portions facing the central body portion.
Claim 10
Dependent Claim
30 words
The device as defined in claim 1, wherein the outer surface of the central body portion has a plurality of raised portions positioned to contact the occlusal surfaces of teeth.
Claim 11
Dependent Claim
20 words
The device as defined in claim 1, wherein the inner surfaces of the first and second flange portions are textured.
Claim 12
Dependent Claim
18 words
The device as defined in claim 1, wherein the resilient, non-toxic material is a medical grade silicone rubber.
Claim 13
Dependent Claim
15 words
The device as defined in claim 1, wherein the resilient, non-toxic material is latex rubber.
Claim 14
Dependent Claim
42 words
The device as defined in claim 1, wherein the surface of said first flange portion facing away from said central body portion is convex and wherein the surface of said second flange portion facing away from said central body portion is concave.
Claim 15
Dependent Claim
22 words
The device as defined in claim 1, wherein said first flange portion has a larger outside diameter than said second flange portion.
Claim 16
Dependent Claim
31 words
The device as defined in claim 1, wherein the first and second dish-shaped flange portions are radially tapered from the root to the tip to increase the flexibility of the flanges.
Claim 17
Independent Claim
257 words
A method of cleaning teeth and massaging gums, comprising the steps of: placing a resilient spool-shaped member at a location between the upper and lower teeth of a user, said spool-shaped member having a central body portion having a substantially circular outer circumference surrounding a central void and having attached substantially circular dish-shaped first and second flange portions said first and second substantially circular dish-shaped flange portions extending radially outward from opposite ends of said central body portion, said first flange portion having a concave surface facing said central body portion to generally conform to the labial surfaces of a user's teeth, said second flange portion having a convex surface facing said central body portion to generally conform to the lingual surfaces of a user's teeth; positioning the teeth on opposite sides of said central body portion between said first and second flange portions; chewing on said central body portion to intermittently collapse said central body portion, thereby moving said concave inner surface of said first flange portion and said convex inner surface of said second flange portion to engage the labial and lingual surfaces, respectively, of said teeth and gums, to thereby clean said labial and lingual surfaces by rubbing said surfaces of said flange portions on said teeth and gums; moving said central body portion to a new location in the user's mouth by rolling said central body portion between the user's teeth without manual intervention; and repeating said chewing and moving steps at each of the locations in the user's mouth to be cleaned.
