Abstract
Abstract A container comprising an inner glass receptacle and a closely adhereing exterior protective sheath substantially covering said receptacle. The exterior protective is comprised of a shaperetaining, preferably thermoplastic resin adapted to restrain and retain glass fragments should the glass receptacle be broken. The sheath is further provided with a plurality of outwardly protruding nodular means that lend a roughened appearance to the sheath surface and which produce a surface elevation variance from the mean thickness of the sheath by between about 6 and 60 percent. This surface characteristic minimizes the container surface frictional resistance, increases shock resistance and provides maximum non-slip characteristics to the sheath when the container is hand-held.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
A shatter-resistant composite bottle having base means, side walls and a neck portion comprising a pressurizable inner glass envelope having a mean side wall thickness of between about 0.030 inches and 0.120 inches and a thermoplastic resin outer envelope of a mean thickness of between about 0.004 inches and 0.018 inches surrounds said inner envelope and extends over substantially the entirety thereof said outer envelope being further characterized in that its exterior surface is randomly nodularly configured and has a mean deviation value of about 12 and 18 percent above that of the outer envelope thickness and a mean deviation value of about between 8 and 12 percent below that of the outer envelope thickness.
Claim 2
Dependent Claim
115 words
A shatter-resistant composite bottle having base means, side walls and a neck portion comprising a pressurizable inner glass envelope having a mean side wall thickness of between about 0.030 inches and 0.120 inches and a thermoplastic resin outer envelope of a mean thickness of between about 0.004 inches and 0.018 inches surrounds said inner envelope and extends over substantially the entirety thereof said outer envelope being further characterized in that its exterior surface is randomly nodularly configured and has a mean deviation value of about 12 and 18 percent above that of the outer envelope thickness and a mean deviation value of about between 8 and 12 percent below that of the outer envelope thickness.
Claim 3
Dependent Claim
88 words
A shatter-resistant composite bottle comprising an inner glass envelope having a mean sidewall thickness of between about 0.030 inches and 0.120 inches and an outer envelope of a thermoplastic material having a mean thickness of between about 0.004 inches and 0.018 inches extends over substantially the entirety of said inner glass envelope excepting the finish thereof, the exterior surface of said outer envelope being further characterized in that it is nodularly configured and has a maximum elevation above said mean varying between about 6 and 60 percent thereof.
Claim 4
Dependent Claim
88 words
A shatter-resistant composite bottle comprising an inner glass envelope having a mean sidewall thickness of between about 0.030 inches and 0.120 inches and an outer envelope of a thermoplastic material having a mean thickness of between about 0.004 inches and 0.018 inches extends over substantially the entirety of said inner glass envelope excepting the finish thereof, the exterior surface of said outer envelope being further characterized in that it is nodularly configured and has a maximum elevation above said mean varying between about 6 and 60 percent thereof.
Claim 5
Dependent Claim
32 words
A shatter-resistant composite bottle according to claim 2 wherein said outer envelope is additionally characterized in that its maximum deflection below said mean thickness varies between about 20 and 40 percent thereof.
