Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
Tray means for holding a mass of dough-like uncured silicone material in the shape of a rod bent into a U shape while forcing the upper teeth into such mass and thus forcing the inner, outer and lower surfaces into conforming contact with the whole inner trough-defining surface of such tray means, said tray means comprising two separable troughed portions, one of which has an inner surface in such contact with at least approximately one half of the total of such inner, outer and lower surface area, and the other of which includes an exposed outer surface and is separately movable away from such first portion and from such mass without disturbing such contact between said mass and said inner surface of said first portion.
Claim 2
Dependent Claim
125 words
Tray means for holding a mass of dough-like uncured silicone material in the shape of a rod bent into a U shape while forcing the upper teeth into such mass and thus forcing the inner, outer and lower surfaces into conforming contact with the whole inner trough-defining surface of such tray means, said tray means comprising two separable troughed portions, one of which has an inner surface in such contact with at least approximately one half of the total of such inner, outer and lower surface area, and the other of which includes an exposed outer surface and is separately movable away from such first portion and from such mass without disturbing such contact between said mass and said inner surface of said first portion.
Claim 3
Dependent Claim
57 words
The combination according to claim 1 wherein said one portion is limp and constitutes a liner for said other portion, and said other portion is semi-rigid to support said one portion and retain the outer shape of such material in substantially the unflexed shape of the trough during such forcing of the upper teeth into such mass.
Claim 4
Dependent Claim
33 words
The combination according to claim 1 wherein said portions are joined along a breaking line and each has an inner surface in contact with a respectively different approximate half of said total area.
Claim 5
Dependent Claim
23 words
The combination according to claim 3 wherein said breaking line is a line of weakness located along the centerline of the tray means.
Claim 6
Dependent Claim
121 words
Dental tray means for holding a generally bent sausage shaped mass of dough-like uncured silicone material during the impressing into such mass of the upper teeth of the prospective wearer of a teeth guard to be formed of such mass, said tray means comprising a trough-defining element of thin, semi-rigid plastic material, sufficiently rigid to retain substantially its unflexed shape during the impressing of upper teeth into uncured silicone putty material therein and sufficiently yielding to permit a small edge portion thereof to be pulled by a fingernail away from the putty material therein, and film means lining the inner trough-defining surface of said element and adapted and arranged to separate such uncured putty material from direct contact with said surface.
Claim 7
Dependent Claim
121 words
Dental tray means for holding a generally bent sausage shaped mass of dough-like uncured silicone material during the impressing into such mass of the upper teeth of the prospective wearer of a teeth guard to be formed of such mass, said tray means comprising a trough-defining element of thin, semi-rigid plastic material, sufficiently rigid to retain substantially its unflexed shape during the impressing of upper teeth into uncured silicone putty material therein and sufficiently yielding to permit a small edge portion thereof to be pulled by a fingernail away from the putty material therein, and film means lining the inner trough-defining surface of said element and adapted and arranged to separate such uncured putty material from direct contact with said surface.
Claim 8
Dependent Claim
28 words
The combination according to claim 5 wherein such film means is a thin film of oil effective as a release coating for the trough-defining surface of said element.
Claim 9
Dependent Claim
50 words
The combination according to claim 5 wherein such film means comprises a highly flexible and limp plastic material liner element lining said trough, said liner element being non-adherent to said tray element and peelable from such putty material when exposed upon removal of said tray element from such liner element.
