Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
An extrudible visually clear gel flavored dentifrice with strengthened flavor, taste and smell sensations, containing evenly distributed therein visible bubbles of gas containing volatilized flavor material and of diameter in the 1 to 4 millimeter range and distributed uniformly throughout the dentifrice so that there are from 2 to 40 bubbles per cubic centimeter of dentifrice, which dentifrice is of attractive appearance and comprises a transparent polishing agent which is of a refractive index matching that of the rest of the dentifrice, is insoluble in the rest of the dentifrice and is in particulate form, with the particles thereof being less than 100 microns in diameter, a gelling agent which is an organic or inorganic gum or thickener which produces a clear gel in the described composition, a vehicle which includes a polyhydric alcohol having a refractive index matching that of the other constituents, and a detergent or foaming agent, and is of a viscosity sufficient to maintain positions of the bubbles suspended therein during a shelf life of 6 months.
Claim 2
Dependent Claim
171 words
An extrudible visually clear gel flavored dentifrice with strengthened flavor, taste and smell sensations, containing evenly distributed therein visible bubbles of gas containing volatilized flavor material and of diameter in the 1 to 4 millimeter range and distributed uniformly throughout the dentifrice so that there are from 2 to 40 bubbles per cubic centimeter of dentifrice, which dentifrice is of attractive appearance and comprises a transparent polishing agent which is of a refractive index matching that of the rest of the dentifrice, is insoluble in the rest of the dentifrice and is in particulate form, with the particles thereof being less than 100 microns in diameter, a gelling agent which is an organic or inorganic gum or thickener which produces a clear gel in the described composition, a vehicle which includes a polyhydric alcohol having a refractive index matching that of the other constituents, and a detergent or foaming agent, and is of a viscosity sufficient to maintain positions of the bubbles suspended therein during a shelf life of 6 months.
Claim 3
Dependent Claim
132 words
A dentifrice according to claim 1 wherein the bubbles are globular and are of air, the polishing agent is a complex aluminosilicate of an index of refraction in the range of 1.4 to 1.5 and of a particle size in the range of 1 to 65 microns, the gelling agent is an inorganic material, the vehicle includes sorbitol and the dentifrice includes a synthetic organic detergent, with the percentages of the mentioned components in the dentifrice being 5 to 50% of polishing agent, 0.5 to 5% of gelling agent, 30 to 85% of polyhydric alcohol vehicle and 0.5 to 5% of detergent, together with 5 to 30% of water, and the dentifrice made is of a viscosity greater than 100,000 centipoises at 25° C. and contains 2 to 20 bubbles per cc.
Claim 4
Dependent Claim
143 words
A dentifrice according to claim 1 wherein the bubbles are of diameters in the 2 to 3 mm. range and 5 to 10 are present per cc., the polishing agent is a sodium aluminosilicate of refractive index in the range of 1.44 to 1.48 and of particle sizes in the range of 1 to 20 microns diameter, the gelling agent is a silicated clay, the vehicle is a mixture of sorbitol and glycerol in a proportion within the range of 1:5 to 5:1 and the detergent is sodium N-lauroyl sarcoside, the percentages of the mentioned components in the dentifrice being 5 to 40% of polishing agent, 0.5 to 3% of gelling agent, 50 to 75% of polyhydric alcohol vehicle, 1 to 3% of detergent and 10 to 20% of water, and which is of a viscosity greater than 200,000 cps. at 25° C.
Claim 5
Dependent Claim
70 words
A product according to claim 1 made by a process wherein the gas-free or substantially gas-free viscous, extrudible gel dentifrice comprising polishing agent, gelling agent, vehicle and detergent or foaming agent is made and bubbles of gas of a size in the range of 1 to 4 mm. diameter of an equivalent sphere are mixed with the dentifrice, which is of a viscosity sufficient to maintain the bubbles suspended therein.
Claim 6
Dependent Claim
32 words
A product according to claim 1 made by a process which comprises degassing a gas-containing dentifrice gel and mixing with such degassed dentifrice gel, in clear state, gel-insoluble gas in bubble form.
Claim 7
Dependent Claim
50 words
A product according to claim 1 made by a process which comprises degassing a gas-containing dentifrice gel, mixing air with such degassed dentifrice gel, in clear state, at an elevated temperature and cooling the gel so as to increase the viscosity thereof sufficiently to maintain the gas bubbles suspended therein.
Claim 8
Dependent Claim
50 words
A product according to claim 2 made by a process which comprises degassing a gas-containing dentifrice gel, mixing air with such degassed dentifrice gel, in clear state, at an elevated temperature and cooling the gel so as to increase the viscosity thereof sufficiently to maintain the gas bubbles suspended therein.
