Abstract
Abstract A container comprising an inner glass receptacle and a closely adhering, but not chemically bound exterior protective sheath substantially covering said receptacle. The exterior protective is comprised of a shape-retaining, preferably thermoplastic resin adapted to restrain and retain glass fragments should the glass receptacle become broken. The sheath is further provided with a plurality of outwardly protruding nodular means that minimize the container surface frictional characteristics, increase shock resistance and provide maximum non-slip characteristics to the sheath when the container is hand-held.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
A container formed as a bottle having base means, side walls and a neck portion comprising an inner glass receptacle and a closely and consistently adhered exterior protective sheath substantially covering the sides and bottom of said receptacle, said exterior protective sheath being comprised of a shaperetaining flexible thermoplastic resin adapted to restrain and retain fragments of said glass receptacle upon breakage, substantially the entirety of the exposed surface of said sheath being further characterized by a plurality of randomly positioned outwardly protruding nodes that are separated one from another by depressions of approximately like size thereto and into which portions of the material forming the nodes may flow upon impact so as to minimize the container surface frictional characteristics, increase the shock resistAnce thereof and provide maximum nonslip characteristics thereto when it is handheld.
Claim 2
Dependent Claim
135 words
A container formed as a bottle having base means, side walls and a neck portion comprising an inner glass receptacle and a closely and consistently adhered exterior protective sheath substantially covering the sides and bottom of said receptacle, said exterior protective sheath being comprised of a shaperetaining flexible thermoplastic resin adapted to restrain and retain fragments of said glass receptacle upon breakage, substantially the entirety of the exposed surface of said sheath being further characterized by a plurality of randomly positioned outwardly protruding nodes that are separated one from another by depressions of approximately like size thereto and into which portions of the material forming the nodes may flow upon impact so as to minimize the container surface frictional characteristics, increase the shock resistAnce thereof and provide maximum nonslip characteristics thereto when it is handheld.
Claim 3
Dependent Claim
15 words
The container according to claim 1 wherein said shape retaining flexible thermoplastic resin is polyethylene.
Claim 4
Dependent Claim
144 words
A container formed as a bottle having base means, side walls and a neck portion comprising an inner glass receptacle having a wall thickness of from about 0.03 to about 0.12 inches and further comprising an exterior adhered contiguous sheath of a flexible shape retaining thermoplastic resin having a thickness of from about 0.004 to about 0.018 inches that is adapted to retain and minimize glass fragmentation in the event of breakage, substantially the entirety of the outer exposed surface of said sheath being provided with a plurality of randomly positioned outwardly protruding nodes that are separated one from another by depressions of approximately like size thereto and into which portions of the material forming the nodes may flow upon impact so as to improve the surface frictional characteristics thereof, protect said receptacle from abrasion and shock, and lend good hand holding characteristics thereto.
Claim 5
Dependent Claim
144 words
A container formed as a bottle having base means, side walls and a neck portion comprising an inner glass receptacle having a wall thickness of from about 0.03 to about 0.12 inches and further comprising an exterior adhered contiguous sheath of a flexible shape retaining thermoplastic resin having a thickness of from about 0.004 to about 0.018 inches that is adapted to retain and minimize glass fragmentation in the event of breakage, substantially the entirety of the outer exposed surface of said sheath being provided with a plurality of randomly positioned outwardly protruding nodes that are separated one from another by depressions of approximately like size thereto and into which portions of the material forming the nodes may flow upon impact so as to improve the surface frictional characteristics thereof, protect said receptacle from abrasion and shock, and lend good hand holding characteristics thereto.
Claim 6
Dependent Claim
15 words
The container according to claim 3 wherein said flexible shape retaining thermoplastic resin is polyethylene.
Claim 7
Dependent Claim
13 words
The container according to claim 3 wherein said thermoplastic resin is acrylonitrile-butadiene-styrene copolymer.
Claim 8
Dependent Claim
13 words
The container according to claim 3 wherein said thermoplastic resin is impact polystyrene.
