Abstract
Abstract A dental hygiene package comprising a container for a body of viscous material including a dental medicament, such as a topical fluoride gel or a gel including a tooth-desensitizing composition. A supply of dental floss is immersed in the body of material thereby to impregnate the floss and adhere to the strands thereof. The container has an orifice through which the medicament-carrying dental floss may be withdrawn. This orifice has a size and shape relative to that of the floss whereby a predetermined and controlled amount of medicament is supplied per length of medicament-carrying floss drawn through the orifice from the container. A cutter is secured to the container for severing the medicament-carrying floss into desired lengths.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
134 words
A dental hygiene package comprising: a container; a body of viscous material including a dental medicament in said container, said material hving a viscosity in the order of between 2,500 and 78,000 centipoises; a supply of dental floss immersed in said body of material thereby to impregnate the floss and adhere to the strands thereof; an orifice in said container through which the medicament-carrying dental floss may be withdrawn from said container, said orifice being of a size substantially larger than the cross-section of the floss and having a size and shape relative to that of the floss whereby a predetermined and controlled amount of medicament is supplied per length of medicament-carrying floss drawn through the orifice from said container; and means secured to said container for severing the medicament-carrying floss into desired lengths.
Claim 2
Dependent Claim
134 words
A dental hygiene package comprising: a container; a body of viscous material including a dental medicament in said container, said material hving a viscosity in the order of between 2,500 and 78,000 centipoises; a supply of dental floss immersed in said body of material thereby to impregnate the floss and adhere to the strands thereof; an orifice in said container through which the medicament-carrying dental floss may be withdrawn from said container, said orifice being of a size substantially larger than the cross-section of the floss and having a size and shape relative to that of the floss whereby a predetermined and controlled amount of medicament is supplied per length of medicament-carrying floss drawn through the orifice from said container; and means secured to said container for severing the medicament-carrying floss into desired lengths.
Claim 3
Dependent Claim
30 words
A package as set forth in claim 1 in which the severing means comprises a cutter blade with means for temporarily retaining the unsevered portion of the withdrawn medicament-carrying floss.
Claim 4
Dependent Claim
18 words
A package as set forth in claim 1 in which the body of viscous material is a gel.
Claim 5
Dependent Claim
29 words
A package as set forth in claim 3 in which the viscous material is a gel having a viscosity in the order of between about 25,000 and 45,000 centipoises.
Claim 6
Dependent Claim
20 words
A package as set forth in claim 3 in which the medicament is one that is soluble in the gel.
Claim 7
Dependent Claim
29 words

Claim 8
Dependent Claim
55 words
A package as set forth in claim 6 in which the concentration of the fluoride compound and the amount of material carried by the floss is such that the concentration of the fluoride ions supplied by the medicament carrying floss is between about 0.01 mg. and 0.2 mg. of fluoride ions per centimeter length dispensed.
Claim 9
Dependent Claim
45 words
A package as set forth in claim 7 in which the viscous material is a gel and in which the concentration of the fluoride compound in the gel is such that the gel will have a fluoride ion cencentration of between about 0.1 and 2%.
Claim 10
Dependent Claim
15 words
A package as set forth in claim 1 wherein the medicament is a tooth-desensitizing composition.
Claim 11
Dependent Claim
15 words

Claim 12
Dependent Claim
47 words
A package as set forth in claim 10 in which the concentration of the strontium chloride and the amount of material carried by the floss is such that the strontium chloride carried by the floss is between about 0.6 mg. and 5.5 mg. per centimeter length dispensed.
Claim 13
Dependent Claim
32 words
