Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
An antiseptic dental floss comprising a flexible length of floss having a first portion of thin, smooth, homogeneous conventional floss and a second portion of non-homogeneous compressible material of generally larger diameter than the first portion, wherein said material includes dental floss conbined with fluid antiseptic wherein the floss has means for retaining the antiseptic discharging said antiseptic responsive to external pressure created by drawing the second portion through ones teeth, wherein the said means comprises roughened flexible enterior floss surfaces protruding radially beyond the diameter of the first said portion creating recesses for the deposition, retention and subsequent oozing discharge of antiseptic from the second portion to the teeth surfaces responsive to compressive pressures.
Claim 2
Dependent Claim
115 words
An antiseptic dental floss comprising a flexible length of floss having a first portion of thin, smooth, homogeneous conventional floss and a second portion of non-homogeneous compressible material of generally larger diameter than the first portion, wherein said material includes dental floss conbined with fluid antiseptic wherein the floss has means for retaining the antiseptic discharging said antiseptic responsive to external pressure created by drawing the second portion through ones teeth, wherein the said means comprises roughened flexible enterior floss surfaces protruding radially beyond the diameter of the first said portion creating recesses for the deposition, retention and subsequent oozing discharge of antiseptic from the second portion to the teeth surfaces responsive to compressive pressures.
Claim 3
Dependent Claim
38 words
A dental floss as in claim 1 wherein the said means comprises a central bore in said second portion filled with antiseptic and including spaced discharge orifices for discharging the antiseptic from the bore to the floss exterior.
Claim 4
Dependent Claim
58 words
A dental floss as in claim 2 wherein said means comprises a longitudinal slot extending for a full diameter from one side of the second portion to the opposite diametral side, said slot being filled with a porous flexible material impregnated with antiseptic, whereby compressive pressure on the floss exterior squeezee the antiseptic out from the porous material.
Claim 5
Dependent Claim
15 words
A dental floss as in claim 3 wherein the slot includes an axial circular portion.
