Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
A disposable single use protective cover apparatus for a dental cure light of the type having an approximately cylindrical distal light probe, said light probe having a nominal diameter, comprising: an elongate transparent polymeric substantially tubular sheath member having an effective diameter larger than said light source nominal diameter, and having a predetermined first length; a distal cover member, having a diameter smaller than said nominal light source diameter, and having a predetermined second length, forming a tubular distal cover member; and whereby, said tubular distal cover member is deformed into conformity with said distal light source by stretching said tubular distal cover member over said distal light probe.
Claim 2
Dependent Claim
109 words
A disposable single use protective cover apparatus for a dental cure light of the type having an approximately cylindrical distal light probe, said light probe having a nominal diameter, comprising: an elongate transparent polymeric substantially tubular sheath member having an effective diameter larger than said light source nominal diameter, and having a predetermined first length; a distal cover member, having a diameter smaller than said nominal light source diameter, and having a predetermined second length, forming a tubular distal cover member; and whereby, said tubular distal cover member is deformed into conformity with said distal light source by stretching said tubular distal cover member over said distal light probe.
Claim 3
Dependent Claim
36 words
The apparatus of claim 1 wherein said tubular sheath member and tubular distal cover member form a unitary structure formed from substantially planar films joined at a seam extending along the length of said elongate sheath.
Claim 4
Dependent Claim
16 words
The apparatus of claim 1 or claim 2 wherein said polymeric material is ethylene methacrylate film.
Claim 5
Dependent Claim
141 words
A disposable single use protective cover apparatus for a dental cure light of the type having an approximately cylindrical distal light probe, said light probe having a nominal diameter, comprising: an elongate transparent polymeric substantially tubular sheath member having an effective diameter larger than said light source nominal diameter, and having a predetermined first length; a distal cover member, having a diameter smaller than said nominal light source diameter, and having a predetermined second length, forming a tubular distal cover member; and whereby, said tubular distal cover member is deformed into conformity with said distal light source by stretching said tubular distal cover member over said distal light probe, an upper release liner; a lower release liner; said upper release liner and said lower release liner together forming a sheath reception area for positioning and protecting said sheath prior to use.
Claim 6
Dependent Claim
141 words
A disposable single use protective cover apparatus for a dental cure light of the type having an approximately cylindrical distal light probe, said light probe having a nominal diameter, comprising: an elongate transparent polymeric substantially tubular sheath member having an effective diameter larger than said light source nominal diameter, and having a predetermined first length; a distal cover member, having a diameter smaller than said nominal light source diameter, and having a predetermined second length, forming a tubular distal cover member; and whereby, said tubular distal cover member is deformed into conformity with said distal light source by stretching said tubular distal cover member over said distal light probe, an upper release liner; a lower release liner; said upper release liner and said lower release liner together forming a sheath reception area for positioning and protecting said sheath prior to use.
Claim 7
Dependent Claim
48 words
The apparatus of claim 4 further comprising: an upper grip tab formed on said upper release liner; a lower grip tab formed on said lower release liner; said upper grip tab and said lower grip tab together forming means for applying said sheath to said cure light tip.
