ABSTRACT:
Barrier structure placeable as a projectile-disabling, anti-liquid-leakage protective shield for the outside surface of a container designed to hold liquid of a certain nature including (a) a first-type (innermost) layer formed as an expanse of high-elastomeric material which is substantially fully self-healing via elastomeric behavior with regard to a piercing projectile wound, (b) a second-type (intermediate) layer disposed adjacent one side of the first-type layer as an expanse including a body of substantially the same high-elastomeric material in which there is contained a distribution of liquid-imbiber beads which react, and expand three-dimensionally in relation, to contact with liquid of the mentioned certain nature, and (c) a third-type (outermost) layer disposed adjacent the second-type layer, and formed as an expanse of substantially the same high-elastomeric material employed in the first- and second-type layers. In one embodiment of the invention, these layers are dimensioned whereby the first- and third-type layers each possesses a thickness substantially twice that of the second-type layer, and in a second invention embodiment, no matter the thickness of the innermost layer, that of the outermost layer is substantially twice that of the intermediate layer.
