Abstract
Abstract This disclosure describes an inner, protective flexible linear or band which is positioned adjacent the inner radial wall of a pneumatic tire, said linear having a plurality of structural blocks sandwiched therebetween, said plyable sheets along with block structures form fluid retaining pockets whereby a selfsealing fluid composition is encased therein, said fluid being released to fill an aperture formed by a puncture to the pressurized tire.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
A flexible band positioned within a pneumatic tire and adjacent the inner radial wall thereof, having in combination and comprising: a plurality of annular flexible sheets; a plurality of block structures attaches to and sandwiched between said sheets, said blocks being contiguously arranged so as to form a multiplicity of pockets therebetween; and a fluid sealant material interposed within said pockets and wherein said sealant material may flow into an aperture produced by a puncture in said pressurized tire.
Claim 2
Dependent Claim
79 words
A flexible band positioned within a pneumatic tire and adjacent the inner radial wall thereof, having in combination and comprising: a plurality of annular flexible sheets; a plurality of block structures attaches to and sandwiched between said sheets, said blocks being contiguously arranged so as to form a multiplicity of pockets therebetween; and a fluid sealant material interposed within said pockets and wherein said sealant material may flow into an aperture produced by a puncture in said pressurized tire.
Claim 3
Dependent Claim
196 words
A flexible, annular linear positioned within a pneumatic tire and adjacent the inner wall thereof, having in combination and comprising: a first outer radial stretchable band, one face thereof being in radial contact with said inner wall of said tire; a first layer of contiguously arranged blocks secured to the opposite face of said first radial band, said blocks having outer walls defining pockets therein; a second flexible sheet seCured to the under side of said blocks and thereby defining a multiplicity of voids formed by the walls of the sandwiched-between said first and second flexible sheets; a second layer of contiguously arranged blocks secured to the opposite side of said second flexible sheet, said second layer of blocks being offset from said first layer, so that each block of said second layer is positioned under each void; a third flexible sheet secured to the under side of said second layer of blocks forming a multiplicity of enclosed voids, each of said voids being positioned under each of said blocks of said first layer; and a fluid sealant material disposed within each of said voids, whereby apertures made in said tires by punctures may be filled.
Claim 4
Dependent Claim
196 words
A flexible, annular linear positioned within a pneumatic tire and adjacent the inner wall thereof, having in combination and comprising: a first outer radial stretchable band, one face thereof being in radial contact with said inner wall of said tire; a first layer of contiguously arranged blocks secured to the opposite face of said first radial band, said blocks having outer walls defining pockets therein; a second flexible sheet seCured to the under side of said blocks and thereby defining a multiplicity of voids formed by the walls of the sandwiched-between said first and second flexible sheets; a second layer of contiguously arranged blocks secured to the opposite side of said second flexible sheet, said second layer of blocks being offset from said first layer, so that each block of said second layer is positioned under each void; a third flexible sheet secured to the under side of said second layer of blocks forming a multiplicity of enclosed voids, each of said voids being positioned under each of said blocks of said first layer; and a fluid sealant material disposed within each of said voids, whereby apertures made in said tires by punctures may be filled.
Claim 5
Dependent Claim
17 words
A flexible, annular linear as recited in claim 2 wherein said blocks are formed of solid rubber.
Claim 6
Dependent Claim
33 words
A flexible, annular linear as recited in claim 3 wherein said blocks are box shaped, and wherein said walls of one layer of blocks overlap the walls of said other layer of blocks.
